A new test release of TL is available from ftp.es.ele.tue.nl as
`/pub/tiggr/tl-0.08.2.tar.gz'.
libtl is rather usable: I've written a special purpose httpd in TLisp. The
available features of libtl, the performance and time-to-implement of this
program rather surpassed my expectations.
STATUS
This is a test release of TL. It is by no means a complete library
(yet). Lost of things are still missing, see the file TODO (in the
TL distribution) for more information.
DESCRIPTION
TL is a basic Objective-C library, which happens to incorporate a
Lisp interpreter, which provides a seamless integration between
Objective-C and Lisp. (It is neither common lisp nor emacs lisp; it
is probably best described by the name tiggr's lisp.) TL provides
mark & sweep garbage collection to instances of TLObject or a
subclass thereof.
TL provides the following classes: The `root' object TLObject, a
patch for existing root objects (like TLPatchObject), TLString (and
TLMutableString), TLRange, TLDictionary plus enumerators
(TLDictionaryEnumerator, TLDictionaryDictEnumerator,
TLDictionaryKeyEnumerator, TLDictionaryValueEnumerator), basic
streams (TLFDStream, TLFILEStream), TLSocketStream
(TLInetSocketStream, TLUnixSocketStream) plus addresses
(TLInetAddress, TLUnixAddress), TLStringStream
(TLConstantStringStream, TLMutableStringStream), TLBase64Stream
(TLBase64InputStream, TLBase64OutputStream), various other streams
(TLBufferedStream, TLHTTPStream, TLSneakStream, TLStreamStream,
TLSyslogStream, TLTelnetStream, TLWrapStream), lisp specific classes
(TLCons, TLConsEnumerator, TLLDelegate, TLLInvocation, TLLLambda,
TLLLex, TLLSubroutine, TLLTag, TLNil, TLSymbol, TLSymbolValue) and
various others: TLDate, TLMimeItem, TLNumber, TLRunLoop, TLURL,
TLVector and TLVectorEnumerator. Furthermore, it includes a host of
Lisp invokable (but C written and thus also C invokable) functions.
If reference counting is not provided by another library, TL
provides reference counting and an NSAutoreleasePool.
TL has been tested on HP9000/735 HP-UX 9.05 with the GNU runtime,
and on a NeXTstation Mono Turbo NS3.3 with the NeXT runtime.
TL is distributed under the GNU General Public License. TL comes
WITHOUT ANY WARRANTY. See the file LICENSE in the TL distribution
for details.
TL is available through anonymous FTP at
HREF="ftp://ftp.es.ele.tue.nl/pub/tiggr/tl-0.08.2.tar.gz"
Changes in version 0.08.2
New classes: TLConsEnumerator, TLDate, TLRunLoop, TLStreamStream,
TLSneakStream, TLTelnetStream, TLVectorEnumerator.
Removed classes: TLLStringConstant.
Initial support for BSD ttys in Ftcgetattr and Ftcsetattr.
Changed TLEnumerator protocol to be able to handle NIL objects
contained in the object being enumerated.
Split `-flush' stream method into `-flushInput' and `-flushOutput'.
Fixed numerous bugs and mis-features.

In modern computer graphics the method often used is to create your
"world" using as generic a system as possible, which is then mapped
to the computers' own graphical coordinate system. Although incurring
a slight performance penalty, this approach has several advantages,
not least of all portability, between both machines and situations.
In general I would recommend going with a mathematically intuitive
approach for choosing your coordinate system as this helps a great
deal when applying transformations to the objects within. I generally
use (0,0,0) as the "true" centre of world space, where x=0 and y=0
are mapped to the centre of the screen in "display space", and z=0
denotes the position of the screen on the z axis. Most often used
directions are X increasing from left to right, Y increasing from
bottom to top, and Z decreasing as it gets further away from "you".

In FoundationKit, the NSScanner object has a method which converts
string objects containing the printed representation of a long long
into a long long data type:
- (BOOL)scanLongLong:(long long *)value
Scans a long long int into value if possible. Returns YES if a valid
integer expression was scanned, NO otherwise. LONG_LONG_MAX or
LONG_LONG_MIN is put in value on overflow.
(The *_MIN and *_MAX constants are defined in limits.h header file for
your particular architecture.) The NSValue class in FoundationKit also
seems to be long long savy.
Alternatively, the g++ libraries on the NeXT appear to know a little
about long long as well and the declaration of the iostream operators
istream & ostream indicate that they can read and write them, both
signed and unsigned.
The /usr/include/architecture/byte_order.h file has routines it in to
byte swap long long types if needed.

Hi!
I want to draw a line in a view to show the actually position. I choose
instance drawing.
The problem is that nothing is visible until the scrollview begins
scrolling. Now it works fine.
Ive tried DSPFlush(), -flushWindow and other things to display the instance
drawing. nothing.
The following code I used:
PSsetinstance (YES);
PSnewinstance ();
PSnewpath ();
PSsetlinewidth (0.0);
PSmoveto (displayPosition, 0.0);
PSrlineto (0.0, height);
PSclosepath ();
PSsetgray (NX_DKGRAY);
PSstroke ();
PSsetinstance (NO);
HOW CAN INFORM THE WINDOW SERVER TO DISPLAY THE INSTANCE DRAWING WITHOUT
DISPLAYING THE WHOLE VIEW?
Thanx for any help, Gerald

The answer to this question is in NextAnswer 1861, attached.
Q: My application is a simple paint program. The user opens a TIFF image,
then scribbles into it, and finally saves the new image as a TIFF file.
However, the changes made by the user aren't saved into the TIFF file˜it
contains the original image. Why?
A: This occurs if you open the TIFF file like this:
image = [[NXImage alloc] initFromFile:fileName];
NXImage will have two representations˜the file, and the cache. NXImage
will treat the cache as a transitory image, and the file as its "best
representation." The cache is the off-screen window to which the user's
scribbles are drawn. When asked to write out the image, NXImage writes out
its best representation of the image˜which is the actual TIFF file residing
on disk˜thus ignoring completely the changes made to the image. To get
around this you must fake out NXImage by forcing the cache to be the best
representation of the image.
The following code snippet illustrates what you must do:
/* When the user opens the image */
rep = [[NXBitmapImageRep alloc] initFromFile:fileName];
[rep getSize:&imageSize];
image = [[NXImage alloc] initSize:&imageSize];
if ([image useCacheWithDepth:d] && [image lockFocus]) {
[rep draw];
[image unlockFocus];
}
[rep free];
This code sample initialized an NXBitmapImageRep from the file containing
the opened image. The NXImage is initialized from this representation.
Now the NXImage does not have a file which can serve as its best
representation˜it only has the cache. Thus when you tell NXImage to
writeTIFF: the cache with all of the user's scribbles is written out
properly.

Edit's listener (see the docs on the Speaker and Listener classes in the
appkit (especially Speaker under Sending Remote Messages)) responds to a
method:
- openFile:(char *)file onHost:(char *)host atTrueLine:(int)line;
To use the current host, the host parameter should be an empty string:"".

-respondsTo: will be forwarded to the real object and return *it's* answer, so
things should work transparently. Have you tested your assertion at all?
Besides, you shouldn't implement delegation by providing a default method in
Object. Did NeXT do that anywhere (declarations don't imply implementation)? I
don't think so! The reason is that delegation (NeXT's use of this term, which
is quite distinct from delegation in a language like Self where it replaces
inheritance itself) is quite crude: an object typically supports only one
delegate, yet different messages can be handled either by that delegate or by
the object itself (if a subclass implements the delegate method). Combined with
the concept of (dis)allowing an operation by returning self or nil for certain
...Will... messages, you would need three values to distinguish between:
- delegate doesn't implement this (doesn't override from Object), so try the
delegating object itself
- delegate doesn't allow the operation
- delegate allows the operation
Which values will you use? self, nil, and anything else? Will every other NeXT
programmer use the same convention?
So avoid the confusion and use respondsTo: in all cases. Of course, NeXT should
really document all of this, because it conceived this protocol (general
meaning).

Gerald,
I must admit I have not actually tried this out, but I think that all you
need is an NXPing() after the PSstroke().
Not that it matters, I think the PSnewpath and PSclosepath are not necessary
in this case.
As a possible alternative, I have a ruler for a Text object that supports
right, centre and decimal tabs. As the ruler tokens are dragged across the
ruler, I use NXHighlightRect() to draw a vertical line down the Text as the
token is dragged. I find this superior to instance drawing. If you try using
NXHighlightRect, you will need a flushWindow in the loop.
Let me know if NXPing() doesn't work and I'll work out an example that does
work and send it to you.

Well, theoretically, you can compile for POSIX by using dirent instead of
direct, using the appropriate headers, and so forth.
Practically, of course, the readdir() function in libposix.a is buggy (it can
fail to read all entries in a directory--work around by writing your own
readdir() or swiping code for readdir() from another POSIX system).

I seem to remember netpbm tools allow for this.
The netpbm tools is a superset of pbmplus set of cmd-line-tools.

Message-ID: <9507021807.AA00231@localhost>
I have seen somebody posting about this topic, but unfortunately I
haven't caught his email then. So I post my proposal here; sorry for
this pollution.
Since ObjC does a objc_msgSend call for each message sent and goes
through a lookup loop ("virtually as quick as a C-call would be" ;-)
there is some overhead.
Look at the output of the program - added to the end of the article
for those who want to reproduce (NeXTStation mono -O2):
Seconds elapsed:1.640625
Seconds elapsed:1.640625
Seconds elapsed:1.625000
Seconds elapsed:0.625000
The first 3 are ObjC the last is C.
A factor of something above 2.5 seems not bad even since further
subclassing is cached effectivly (1st compared with the 2nd).
But if you really build the Data Model of your application on ObjC
(for which EOF is an example) this effectivly means that messages
will dominate function calls even in computational tasks.
So how to improv?
Another jumptable may help. For each message call with a !static!
selector (which dominates at 99.53% from my totally arbitrary
assumption) an entry in the jumptable would contain the receiving
object's id and the address of the method machine code (as obtained
by methodFor:). Then the assembly (m68k) could look like this
(yielding performance like C++-virtual functions:
; assumed things are right on the stack
lea jmptableaddr,a0 ; jmptableaddr points at a the
entry ; of the jumptable corresponding to
; this message (a0) is the object
; (4,a0) is the method's address
cmp (sp),(a0) ; (sp) is the receiving object
beq jumpAway ; has the object changed?
pea (a0)
jsr correctJmpTable
addq #4,sp
lea jmptableaddr,a0 ; a0 may be destructed
jumpAway:
jsr ([4,a0],X0,0) ; we can directly call the code now
; (where X0 is the dummy register)
retAddress:
; things go their way
...
correctJmpTable: ; this occures only once in the
; program
; find_out_new_method_address something similar objc_msgSend
rts
This should not require many changes to gcc and should be fully
architecture independend. However codesize would increase here by 26
bytes a message plus 8 bytes for lookup.

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>

I'm polishing up my base modifications to the SoundBlaster8 driver to
support Jazz16 chipset based sound boards. Specifically, I've got a
Mediavision Deluxe Sound card in my Pentium. These modifications are based
off of the VoxWare 3.0 beta sound drivers for Linux and were rather
straightforward and simple. I've only concentrated on playback and have
not tested recording yet.
For the most part, it works - no clicking or dropouts with 22khz stereo or
44.1khz mono playback. 44.1khz stereo playback works flawlessly most of
the time. I've even played "Vision in Black" without any glitches from
CD-ROM. What does not work are: 16 bit DMA transfers (I think this is a
hardware problem) and therefore 16 bit DMA channels and NEXTIME movie
playback. Specifically, if I install the NEXTIME sound driver, I don't get
any hardware interrupts anymore! If I don't install that driver, the
sounds play just fine but the video isn't synchronized to the sound. A
ProAudio Spectrum 16 in the same machine plays back NEXTIME with sound
without this problem (it's got tons of other problems).
Anyone out there can help?
Thanks!
..Bill Chin
p.s. Also, if you are interested in beta testing this driver, please e-mail
me. People willing to dig into DriverKit and debug a driver only at this
point! Thanks!

OK, I don't know what to do and am certain that it is stupid.
I cannot get my internal Gateway/2000 FAX modem to work.
I have retrieved the latest serial drivers from NeXT and successfully
installed them.
However, if I

I hear the dial, hear the ring, hear the search for matchup, get a "connect"
and then nothing.
If I
tip a9600 (or cufa9600 or any similar from the std etc/remote)

No modem directives work, ATDT, ATH, etc.
When I boot DOS/Windows I can dial out just fine, as I have done just now

That s right, I made a mistake and wrote a wrong thing. Sorry. I
made a test : I sent respondsTo(@selector(takeFloatValueFrom:) to a proxy

Hi all:
I need an easy way to generate images from postscript files. I
figured that I could use the pstopnm program that's part of netpbm,
but it requires ghostscript. I've compiled ghostscript 2.6.2, and it
works like a champ, but I can't seem to get it to recognize the fonts
I have installed.
Does anyone know how to do either of the following: (1) get
ghostscript to recognize the fonts I already have installed, or (2)
get pft to work with the ps2ppm.ps file that's included with the
ghostscript distribution?
Thanks in advance....

Forget ``crude''. There are limitations, of course; Foundation Kit

In its simplest form what I am looking for a mechanism for entering

Does anyone have the source code to one of these Auth code encryption

It is a shameful, shameful, shameful bug in the Text object. NeXT never
programmed it for color, and any color support in it is a graceless
hack. Will they ever fix it? Depends on whether or not it generates a
new 1000 seat order or not for MCCA seats.
I'll bet on Sun's working right though.

I have seen somebody posting about this topic, but unfortunately I
haven't caught his email then. So I post my proposal here; sorry for
this pollution.
Since ObjC does a objc_msgSend call for each message sent and goes
through a lookup loop ("virtually as quick as a C-call would be" ;-)
there is some overhead.
Look at the output of the program - added to the end of the article
for those who want to reproduce (NeXTStation mono -O2):
Seconds elapsed:1.640625
Seconds elapsed:1.640625
Seconds elapsed:1.625000
Seconds elapsed:0.625000
The first 3 are ObjC the last is C.
A factor of something above 2.5 seems not bad even since further
subclassing is cached effectivly (1st compared with the 2nd).
But if you really build the Data Model of your application on ObjC
(for which EOF is an example) this effectivly means that messages
will dominate function calls even in computational tasks.
So how to improv?
Another jumptable may help. For each message call with a !static!
selector (which dominates at 99.53% from my totally arbitrary
assumption) an entry in the jumptable would contain the receiving
object's id and the address of the method machine code (as obtained
by methodFor:). Then the assembly (m68k) could look like this
(yielding performance like C++-virtual functions:
; assumed things are right on the stack
lea jmptableaddr,a0 ; jmptableaddr points at a the
entry ; of the jumptable corresponding to
; this message (a0) is the object
; (4,a0) is the method's address
cmp (sp),(a0) ; (sp) is the receiving object
beq jumpAway ; has the object changed?
pea (a0)
jsr correctJmpTable
addq #4,sp
lea jmptableaddr,a0 ; a0 may be destructed
jumpAway:
jsr ([4,a0],X0,0) ; we can directly call the code now
; (where X0 is the dummy register)
retAddress:
; things go their way
...
correctJmpTable: ; this occures only once in the
; program
; find_out_new_method_address something similar objc_msgSend
rts
This should not require many changes to gcc and should be fully
architecture independend. However codesize would increase here by 26
bytes a message plus 8 bytes for lookup.

Subject: PLEA: Help with 'performv'
Date: Sun, 02 Jul 1995 14:22:48 -0400
Organization: Tudhope Associates Inc.
Distribution: world
Message-ID: <dcell-0207951422480001@tudhope.tor.hookup.net>
A simple question, I hope: Does 'performv' give an object a chance to
forward a message? It doesn't appear so...
I want to be able to add methods to Application without the restrictions
of a category or '+poseAs' (i.e. no new instance variables). Actually,
what I REALLY want is a global object (like NXApp). I know this goes
against all OO tenets, but it seems to be an extremely efficient way to
implement a custom preferences function without having to pass around a
prefs object ad nauseum. If there's a simple way to do this, I would ask
that someone enlighten me. Otherwise, though I may be waaaaaaay off,
here's my approach:
I have defined a category of Application that consists only of a forward
method. This method forwards messages it can't handle to Application's
delegate (my code). To avoid having to put all preference functionality in
my main class (the one that handles menu choices, etc.), I have it forward
*those* messages to my Preferences object.
Ok. All fine and good. Everything trundles along properly, everyone
responds properly to respondsTo. Everyone's happy... until NXApp (in the
Forward category I defined) sends a performv to my code. An error results,
because my code can't actually respond to the message. I was counting on
being able to forward the message to my preferences object, but 'forward'
is never executed. The error results instead.
I could just put all the preferences methods in my main class and all
would be well with the world... but that's admitting defeat. I want it to
work the way I want it to work, dammit!
If anyone has any ideas, or can tell me of a better way of handling the
situation (and please don't say "use NXDefaults" - I don't like that
mechanism) please let me know either here or in Email (dcell@tudhope.com).
Thanks in advance!

I haven't been watching this list for a while - so if I'm asking already heavy
discussed stuff, please be patient...:
Has anybody the slightest idea of how NeXT is going to deal with the problem of
cyclic references in their reference-counting mechanism in OpenStep
(retain/release)?
----- if this is stuff from yesterday stop reading here...
A short outline of the situation:
- A new document is to be created in a standard OpenStep-app
- An instance of class 'DocumentController' gets allocated
- The object that allocated it (e.g. NXApp) holds _one_ reference to this
DocumentController
- The DocumentControllers nib-file gets loaded
- DocumentController has an outlet 'window' which gets set to reference a
window loaded from the nib-file
- The window references (over some subviews) a button
- This button has an outlet 'target' which gets set to reference the
DocumentController
Question:
Does the button have to retain the DocumentController?
Actually it has an instance variable of type id pointing to it, so it would
have to retain it.
But if it does, the DocumentController is then referenced by _two_ objects!
If the object (e.g. NXApp) who allocated him, releases him, he won't be
deallocated and the whole chain DocumentController->Window->..views..->Button
is hanging in the air.
So how is the programmer supposed to know, if he may/has_to retain an object to
which he holds a reference (has a variable of type id pointing to it)?

Well, you could define a Preferences class and design it to create a
single shared instance similar to OpenPanel. E.g., you define a local
global variable (a.k.a., an Objective-C class variable :-) in your
Preferences class that points to the shared instance: sharedInstance.
Define a class method named "sharedInstance". If sharedInstance is nil
when sharedInstance is invoked, a new Preferences object is allocated,
initialized, and assigned to sharedInstance. sharedInstance is returned.
Using this approach, you can always access your Preferences instance
without using a global variable of your own (of course, class names are
global variables in a sense):
#import "Preferences.h"
Preferences *preferences = [Preferences sharedInstance];

Don't be so sure, having unretained references can easily cause objects to be
deallocated while other objects still have dangling references to their old
addresses. If those references are ever dereferenced, it can crash an app
instantly.

I agree its an improvement, but still not a particularly well documented one.

Although this whole issue of cyclic references is tricky, I don't
believe that the creation of cyclic references can result in unretained
references that could be deallocated. The problem is just the opposite:
objects involved in cyclic references can't be deallocated but their
pointer variables are usually gone resulting in memory leaks.
Please correct me if I'm wrong.

Is there any simple way to unload all of the objects loaded by a NIB file when the owner is
deallocated? Is this done automagically, or can it be done at all?
In my program, many objects have there own NIB files. These provide inspectors,
miscellaneous panels and supporting objects. When I no longer need an object, I would
like to be able to free the whole shebang with one simple message.
I have hunted through all the documentation, but I can't find any reference to freeing
NIBs.

Why not define a "well-known" method to access the Preferences object
and use that to access it? You can do something like:
- preferencesObject { return _preferencesObject; }
in NXApp's delegate, and always have access to it via:
id prefsObject = [[NXApp delegate] preferencesObject];
You have the added advantage of being able to lazily create the
object in the delegate, i.e.,:
- preferencesObject
{
if(!_preferencesObject) {
_preferencesObject = [[Preferences alloc] init];
}
return _preferencesObject;
}
This gives you a globally accessible Preferences object without
having to maintain a pointer to the instance everywhere you want
to refer to it.

This is an equally good, probably more elegant, solution (to the
NXApp delegate method) as long as you are aware of the issues with
shared instances and subclassing (a discussion that appeared here
a while back...).

Thanks for the help, Art! Also, Thanks to Scott Hess and Allan Noordvyk
for your Email responses.
Putting all the ideas together, I decided to do the following:
I did define the category of Application that consists only of a forward
method. In this category I defined a local global variable similar to what
Art (and Allan) outlined: "static Preferences *prefs = nil;". When this
forward method is first invoked, it checks to see if the 'prefs' variable
is nil, allocating and initializing as necessary. It then forwards the
unknown message to 'prefs' - if it can handle it, of course.
This works quite well, actually. Because it's being initialized from the
forward method, it's completely transparent to my application. It's as if
NXApp has gained a complete preferences functionality - without the
restrictions of a category or '+poseAs'. I just have to be careful that
all my method names are unique to my class. The only catch is that the
prefs object must be specifically freed by my application. Because
Application already has a 'free' method, it never gets forwarded to my
prefs object. No big deal, but if there's a way around that, please let me
know.
Again, thanks for the help!

Usually the files-owner should have access to all objects in the NIB-file
directly or indirectly over one of it's instance variables. If this is the
case, freeing the files-owner should automatically free all objects included in
the NIB-file.
An example:
4 objects in the NIB-file-window:
files-owner
a document window
instance of FooInspector
an inspector panel
The files-owner should have an outlet to the document window _and_ the
FooInspector instance. The FooInspector instance should have an outlet to the
inspector panel. In the -free method of the files-owner, there should also be
sent a -free message to the document window _and_ the inspector, which should
then also free the inspector panel. As -free of Window also frees its content
view and all its subviews there shouldn't be anything left then (unless you're
using OpenStep an have a cyclic reference problem :-)
Hope it helps.

You're right with what you said.
What I meant to say was that programmers are forced to rely on less safe
mechanisms if they need to reclaim memory, such as not retaining some
references in order to prevent cycles. Though manageable in certain
circumstances, having unretained references can lead to crashes.
Since the alternative may be a (minor or major) memory leak, we may be forced
into that situation

nibs are just containers that store archived objects.
Thinking of loading a nib as roughly a shortcut for allocing, initing and
configuring a network of objects. Except for a few extra messages sent
during the unarchiving process, the end result is the same as if you created
the network of objects by custom objC code.
From this point of view, you should use the same techniques for releasing all
or part of a network of objectss that you use with any objects. The fact
that the objects were unarchived from a nib rather allocated and initialized
isn't really relevant when it comes time to destroy them.

Actually, the solution I used (see my message
<dcell-0507951432120001@tudhope.tor.hookup.net>) seems to avoid the shared
instance problem. If I'm wrong please let me know; I didn't see the
discussion that appeared here a while back.
I am having a discussion in Email with Robert Nicholson
<robert.nicholson@mccaw.com> about using my method as opposed to
subclassing Application (this having the advantage of retaining the super
function). I see a few advantages to my method over subclassing.
First, it requires less effort on the programmer's part to use the module.
No extra steps are necessary in Interface Builder. This is much better
when you consider object reusability.
Second, it's relatively transparent to the programmer. NXApp simply gains
preferences functionality.
Third (and this may be somewhat controversial in OO circles), my method
could conceivably be expanded to provide a kind of clearing-house for
global objects. The category of Application could initialize any number of
objects, then offer messages to them in turn.
How does this last point fit in with OO concepts? Does it break any rules?
Is it defeating the purpose of OO programming? It just seems to make
certain things considerably easier and more elegant.
Thoughts, anyone?

I've no idea how to take it from an "OO" point of view. I would
argue against your idea more because it breaks "The rule of least
surprise/confusion". Saying:
[[NXApp delegate] doSomething];
or
[[Preferences sharedInstance] doSomething];
is much more clear than:
[NXApp doSomething];
My reasoning is that the NeXTSTEP programmer with a reasonable
amount of experience is going to see this and say "Hmm, I didn't
know Application implemented -doSomething", at which point they'll
have to go off and look up where the functionality resides. There's
your confusion. In the first two instances, it is self-evident
where the functionality is implemented.
On the surprise side, what if two of these things which latch onto
NXApp somehow manage to use the same method? Then one of them may
no longer work, and it is unlikely to be obvious to the programmer
_why_. There's your surprise.
In any case, the whole idea goes against a practical rule I've
developed over the past couple years, which is "Say what you mean, and
mean what you say." A very simple example of this is something like:
id obj=[self getObject];
if( obj) {
[obj doSomething];
}
The code "if( obj)" is _really_ a shorthand for "if( obj!=nil)".
What the programmer really meant was "if( obj!=nil)", so my argument
is that that's what the programmer should have said in the first
place.
Drawing that out to the presented example, "[NXApp doSomething]"
is _really_ a shorthand for "[[NXApp findSomeoneToDo:@selector(
doSomething)] doSomething]". In other words, it's certainly a
slick trick, but are you going to remember how it worked in 3 (6,
9, 12, 24) months? After working on 2 (4, 6, 12) other projects?

sorry if this has been asked before, but...
i have a window containing many TextFields, each of which
has its textDelegate pointing to the same object.
when this object receives a textDidChange:sender method, is it possible
to determine which TextField object has been changed ?
all i want is the TextField's tag! why do they make it so difficult to do this ?
why doesn't TextField forward its delegate methods with a little bit
more information - e.g. [textDelegate textDidChange:textobj inTextField:self] ?
IMHO, all objects should support subclassing in IB in the same way that Window
subclasses do. This would make an _enormous_ difference to the flexibility of IB!
to summarise, what i want is something like :
- textDidChange:sender
{
int sender_tag = [[sender sendingObject] tag];
....
cheers for any help,

Well, there is a legal, supported way to find out what objects are in
a nib when in IB. The IBDocuments protocol getObjects: method will fill a
list with all non-connector objects in the nib. Sending each object a
legal, supported listConnectors:forDestination: message would show which
objects aren't connected to any other nib object including the File's
Owner. These connections become pointers to the object when a nib is
loaded. So I would think that any object that doesn't have a connection
to it in IB will end up as a memory leak when loaded (correct me if I've
missed something obvious because I'm thinking off the top of my head :-)
Implementing this test in the IBDocumentControllers protocol
willSaveDocument: method will cause this test to be run whenever a nib is
saved. I currently use a similar approach to check that all required
connections in our complex nibs have been made, that they've been made to
objects of the proper class, etc. I print warnings about missing or bad
connections to a small text panel so that the nib builder can read them.
It would be easy to flag objects that might become memory leaks so the nib
builder can either remove them or connect some other object to them.
This all could be implemented in a simple little palette whose
IBPalette subclass is made a document controller. So even nibs not
created by you could be run through this test to alert you about the
possibility of rogue objects.
So while there's lots of stuff about nibs that is undocumented, NeXT
has provided quite a few peepholes into nibs from within IB via the
various IB protocol methods. I encourage all nib builders to become
familiar with these methods and take advantage of them whenever possible.

Hi -
Yes, I did cringe a little at your glomming behavior on the beloved
and sacred Application class :-)
Here's something to think about - what if you want Preferences
behavior in a non-appkit program (i.e., a command-line tool)?
There is no NXApp in this case...
Putting the behavior in the Preferences class (e.g, via a shared
instance) makes the implementation very portable (it is embodied
completely by the Preferences class itself). Adding it to some
other class means it can only go along with that class.

Hi all.
I'm having troubles with installing NeXTSTEP Developer 3.2 from
my Academic bundle. I don't know if the CD-ROM is corrupt or
the CD-ROM player is malfunctioning but I get a checksum error
on both the DeveloperLibs and the Developertools package.
I copied all files from the CD-ROM to my harddisk and I FTP'd
the latest cc. However I can't compile a single source.
The error-message I get is:
cc: Internal compiler error: program cpp-precomp got fatal signal 11 not found
Any advice would be welcome. I have been waiting for 5 months to start
with NeXTSTEP now. I am getting a little frustrated. (Non-certified hardware,
no money, broken-down SCSI-Disks, the works...)

^1.]
ifFalse: [

^i ].
^0
And actually have it work.
But there are a few caveats.
o If you do certain things wroing it will crash for no apparent reason and
you might need gdb to figure out what went wrong.
o It doesn't seem to work on motorolla and I can't figure out why.
Since I only have limited access to NeXT hardware I am hoping
someone else will be willing to figure this out with my help.

socket number is zero which is a non-socket.
Server Client
socket socket
bind
listen
accept =>

The server assigns a port number to the client and knows the client's family and
address. The client knows the server's port and address and thinks it has a good
connection. The server receives a zero socket number from the accept which stops any
further communication with the client.
What is going on with the Accept that it would return a zero socket?

I've been using the following socket code (for the most part yanked out
of TCP/IP and Network Programming, the bible for socket stuff). It works
quite well under NS--if this code is giving bad answers back too, then
it's probably not a programming thing you've done but some stupid OS
thing. At any rate, it'd be the first place to check. Good luck.
Your main() would run something along these lines:
1. Set global_server_port (an int) to the socket port you're using
(7000-9000 _should_ be fine)
2. Set global_server_addr (a char[256]) to the NUMERICAL TCP address
of the server.
3. set global_server_defined to 1.
4. If you want your server to be multi-forked instead of serial,
set server_type (an int) to SERVER_TYPE_PARALLEL, else to
SERVER_TYPE_SERIAL.
5. If you're a client program,
connect_to_socket(); < here it shouldn't return 0!
6. Else if you're the server program,
wait_on_socket(); < here it shouldn't return 0!
6.5 Use readn(), writen(), and readline() to transfer information,
or roll your own read/write routines.
7. If you're a client program and you need to close, use close()
8. If you're a server program and you need to close and re-loop,
If you're multi-forked, use close(), followed by exit(0)!!!
If you're serial, use close(), then re-loop to, oh, #6.

Fellow cyberstrollers,
I am developing my first major NeXT app and am having a couple of problems
which I cannot seem to solve. I therefore beseech any NeXT whizzkids out
there to help me over these humps. I am using EOF1.1 with a Sybase 4.x
back-end. My problems are:
1. I have MONEY fields in the database (MONEY is float(15,2)) which EOF
translates to float or double. Unfortunately, when the data is displayed
the values are converted to scientific notation e.g. 9.9e7. Not only do my
users not want this, they actually want the data to be formatted with 2
decimal places and with commas every third significant digit i.e. as real
people format it. I have tried forcing the data to integer format
(successfully) but this solved neither of these problems. Does anyone out
there know how I can force an NSNumber field to format as required here or
do I need to sub-class NSValue to do this?
2. When I fetch the table view - which has columns which stretch beyond
the visible width of the view - the horizontal scroll bars seem to align
to the middle of the view. I want these bars to move all the way to the
left when the table view has been populated but I cannot seem to get this
to happen. I am sure that there is a simple solution to thsi one, but it
sure beats me!
3. I have several fields on my windows. Ideally I would like the tab key
to navigate between fields and the return key to performClick on the
default button but I currently have the tab and return key navigating. The
return key only does the performClick: when it is on the last field of the
window. Please don't 'rtm' me on this one - I have read the manual over
and over and it is still not something I have got to work successfully.
Please help...
Regards,
Richard

Wow - encoding whole functions, sending them over the network and recreating
the code on the other side again - possibly for another processor...quite a lot
to ask, isn't it.
If you really want to transfer 'code' over the network there would be 2
possibilities:
1) If you also need resources for the code (NIB, TIFF, Sound, ...):
Create a bundle with the code and all resources in it.
Either load that bundle into the receiver from an NFS-mounted dir
or (I've really done that too) pack the bundle into a tar.Z and push
it over the network-connection. Unpack it at the receiver side and
load it.
2) If you just need code:
Unfortunately the rld library isn't part of OpenStep, but if you
want to do it in NEXTSTEP, you could send the fat-object file with
the code in it over the network connection and load the functions
directly out of the received data-block into the app with all symbols.
See the man page of rld for details.

The HPDJ, the HP Desk- and Laser-Jet PrinterDriver, is available in source code
and should be quite easy to change for another printer.
I don't know an URL for it, but in compressed form it's about 20k, so I could
send it via NeXTMail to you.

What's going on? I $^#&#@* don't know!! I've been wasting days on this problem
and finally had to use a "solution" I really hate to use:
ignore it
Actually the program doing so works for about a year now without error.
What I've done is:
If the select() call says, that there's a connect pending on the main-socket
-> call accept().
If accept() returns an FD of 0 - simply ignore it and try again with
select()...
I _think_ that it has to do with interrupted system calls (as my app has about
40-90 threads, most of them using TCP-sockets through my lib and I often catch
the SIG_PIPE signal), but errno doesn't say anything about that.
If anybody knows better...(sigh)

both [sender superview] and [sender delegate] work, but the delegate approach
is documented (and thus presumably more safe)
Of course, OPENSTEP changes the way works anyway.

Subject: Re: Cyclic references in retain/release-mechanism
Here are a few thoughts for your consideration (be sceptical, most of them are
just *my* thoughts).
The issue is resource management. There is one special branch of that called
memory management, also known as garbage collection (but this is also a
possible technique, so memory management seems more appropriate). Another
branch, currently under attention, would be object management. The difference
would be that an object might stand in for another resource that would be in an
inconsistent state until its stand-in is deallocated (a file, a port, ...), so
that deallocation may have to be synchronous.
How long must the resource exist?
- Lower limit: references exist with the privilege of keeping the resource
alive (important point!).
- Upper limit: all resources must be freed in due time to avoid blocking
machine resources, and some of them must be freed synchronously.
As for the lower limit, there are several sets which can be considered garbage
(and the complement would be the live resources):
- resources which will never be used again (fundamentally unpredictable)
- resources which can never be used again as determined by data flow analysis
- resources which cannot be reached by reference traversal from a set of root
resources
- resources which have no references to them
>From the perspective of resource management, these are strictly shrinking sets
of ever less efficient conservative estimates. Efficient: resources which are
not freed because the system doesn't know any better have a cost in machine
resources. Conservative estimate: any subset of the first set is a conservative
estimate of it from the perspective of resource management (conservativeness is
relative to the current purpose). I don't know about the second set, but the
third is the target of several algorithms. The fourth set is the one obtained
through reference counting, and is the only one of those mentioned here which
is not effective anymore, in the sense that if only resources in this set are
freed, some others may be leaked for eternity (or until the task is terminated,
of course), due to referential cycles (should be obvious by now). A benefit is
that the garbage it detects is detected synchronously.
Now, NeXT has provided a reference counting scheme. This is a conservative
estimate of liveness which has to be complemented with either a policy to avoid
referential cycles, or another, effective, resource management scheme, to have
an effective system. The second alternative seems strange: why then not forget
about reference counting and only use the ``backup'' system? Well, in the right
circumstances, reference counting is cheaper, and may avoid wasting CPU
resources to the backup system; it also provides synchronous freeing where
desired.
Let's consider the policy first. It is clear that such a policy is completely
absent from the current specification. Further investigation shows that part of
the retain/release mechanism is safe: there is a stack of autorelease pools (or
rather, a comb, if multiple threads are allowed), which is fundamentally
acyclic. Any autorelease is immune from leakage (which does not imply that any
other references may not cause leaks to occur), and guaranteed to be really
released when the current autorelease scope exits (the programmer should know
if that is acceptable, which it is in most cases).
It is the other references which cause trouble. How could cycles be avoided
here? Well, one of the goals, rather explicitly stated in the concepts, was to
do away with the concept of transferring ownership, because this is confusing.
Now, the owner of an object is considered to be its creator, which has the
responsibility to free it; others can only retain it for a while longer; I find
this rather strange, as if the reasoning has not settled down. But it is more
useful to consider the original concept of ownership.
Ownership is already present in the context of archiving/encoding objects. Some
references are traversed for this purpose, some are only recorded if the
destination is accessed through another route. The former would be the owned
objects (such as subviews), the latter are not owned. So this concept of
ownership should be familiar anyway, and can therefore be used in resource
management as well. There is one addition: ownership need not be unique, there
can be shared ownership. And what now is a very desirable property of
ownership? It is acyclic! Well, if it is properly thought through, it is; there
is room for human error here, but if you want to mess up a program anyway, you
have other means at your proposal. It should always be clearly documented what
the expectations about ownership are, and transfers of ownership should follow
logically from these basic rules.
Finally, a proposed compatible alternative to retain/release. Firstly,
autorelease can be retained (little joke), although it would be clearer to do
[p autoretain] rather than [[p retain] autorelease]; this could be an NSObject
category. But instead of doing -retain indiscriminately, there would be
separate messages -retainForOwner: and -retainForNonOwner:. The former would be
for instance variables which are considered part of that object (subviews,
image representations, ...), the latter would be only for references (control
targets, delegates, ...). As for implementation, there would be a direct
subclass of NSObject which would pose as NSObject to add these methods and
redefine -dealloc and such. Or rather, several of them: one for production
versions, one for debugging, for example. For -retainForNonOwner:, that
non-owner would be registered for notification of the destination object's
death (through -dealloc in the posing NSObject subclass, possibly): a funeral
list mechanism. For -retainForOwner:, a production version might just use
reference counting, and a debugging version might maintain a list of references
which can be traversed by a debugger. If the retain count instance variable can
contain a pointer, its role might be redefined to contain more information,
such as a list of owners.
As for a backup resource manager, this would also benefit from the explicit
reference graph information inherent to -retainForOwner: messaging. But it may
not even be necessary anymore.
I *might* implement such a scheme someday (for free?); to have it sooner, send
an HP NEXTSTEP system, ``full options''. :-)
Hope this is useful,

The worst thing about the 'double' storage of Money is that it internally

and that's what you see in the text field, which could easily give anyone
in a bean-counting job a heart attack.
I had one of our other programmers write me a Money class that handles money
objects as two integers, and does the right thing for adding and
subtracting, and scalar multiplication. It adopts the EO<Something>Coding
(I forget the name) protocol, so the EOF mechanisms can correctly
instantiate a money object and initialize it.

I don't think that [sender superview] works reliably. Try it when
you've configured a scrollable textField, a very common configuration. In
this case, superview is a clipView which isn't what you want and will
likely crash your app.
How many times have you dragged out a matrix of textFieldCells in IB
and then decided you only needed a single one? Looks like any other
textField, but it remains a matrix of one textFieldCell for which [sender
delegate] will return the matrix which isn't usually what you want.
[[sender delegate] selectedCell] should work in general for both a
textField and a matrix of textFieldCells so is a pretty general solution
(as I now await a flood of exceptions to this assertion :-)

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different

an fd of 0 is perfectly valid - it will return this if the standard
input has been closed. (some shells do this when backgrounding their
processes).
-1 is the only error return from any of the socket related system calls.
use perror(), errno or strerror(errno)

SIGPIPE happens when you're writing down a socket to a process which
has died. The system call will give an indication of this by returning
-1 with errno set to EINTR (interrupted system call). (you only get the indication
if you are catching the signal)

Believe it or not, NXTableView will make visible the column to which you made
your last association. If you simply disconnect and reconnect the first column
of the table view, it should behave as you want.

In my experience both of these languages have significant pros and cons.
One `Pro' of Obj. C is the dynamic binding facility. All member
functions are bound at run-time (unless explicitly instructed otherwise). This
combined with the ability of the system to load code dynamically makes a
powerful, flexible, and _extensible_ development environment far superior to
any other that I know.
A con of Obj. C is... the dynamic binding facility! It is often slower than
the C++ method call. All is not lost however. It is possible to disable this
binding technique under the right circumstances.
A `Pro' of C++, and one that is widely exploited, also happens to violate one
of the basic tenets of object oriented programming, namely the ability to
examine public data members from outside an object. While this is a carry
over from C structures and can be very useful...it violates the principle of
data hiding. Another feature is templates, though I am not sure there is not a
way of implementing similar structures in ObjC.
C++ has some capabilities that (I wish) Objective C provided, such as operator
overloading.
I am sure your question will spur heated debate, but before it gets too hot
I would like to suggest using _both_! NEXTSTEP provides a flexible compiler
that can handle both ObjC and 90% of C++. You can mix and match structures
in ObjC and C++ as well as function (pardon me) method calls.In my most
recent experience, I have mixed C++ numerical methods with ObjC Appkit
methods with satisfying results.

True, this is not possible. The idea is that NSNumbers are simple,
atomic, data-bearing objects, each of which represents a single
number. Situations are rare where it is really critical to be able to
modify the numbers.
If they were mutable, there would have to be several mutable classes,
one for each existing mutable class, and there would be a lot of
redundant API. I guess they decided that this was too high of a price
to pay for the unusual cases where it would be used.
You can use scalar variables (i.e. int, unsigned, float, etc) to hold
intermediate values that change a lot and finish up by storing them in
an NSNumber instance. This would be faster than a mutable NSNumber
class anyways.
Hope this helps,

Its not stupid.
NSNumber instances are by design, IMMUTABLE, just like NSString, NSArray and
NSDictionary.
There are lots of advantages to using immutable objects when applicable -
copies are ultra cheap for one thing. storage can be optimized for another.
If you really need a MUTABLE subclass NSNumber. By all means go ahead and
write one. Or flame NeXT for not creating one. But don't flame them for
making the distinction between mutable and immutable objects in the new class
designs. That in itself is a good move.

Wow, I guess beauty really is in the eye of the beholder, because if there
is one single "feature" in C++ that I hate (and I dislike many of its
"features") it is the ability to do operator overloading. Operator
overloading is the best way I can think of to obscure the meaning of code.

That's absolutely true in many ways; powerful, but very, very easy to
abuse. And once it's abused, you're completely screwed. :/ Also
leads to lots of strange problems.
As for the best features of Objective-C, it would be the extremely
late binding ( :D ) and the run-time system. As for C++'s templates,
static binding, and strong typing, you can get -most- of that with
extra work; whereas C++ defaults, and has a hard time getting away
from, the static binding and hard typing, you have to do some extra
work in Objective-C to static/strong type. Mind you, it can be done,
and if it's your thing, you can always use C++ inside of Objective-C
under NS; they attack at different angles to a similar problem.
Personally, like many, I feel that C++ is hideous. Unfortunately, not
like so many, I don't feel it's a necessary evil. If it's ugly, you
don't kiss it, folks. C++ won't be a prince in any future I can
predict.

Message-ID: <3tuf09$me2@news.CNRI.Reston.Va.US>
I'm using EOF 1.1 on NS 3.3 and have a question about qualified
fetches using the data source. I set up a simple EOQualifier such that my
adaptor generates the following SQL expression...
SELECT t0.CUI, t0.DES FROM umls141 t0 WHERE t0.DES = 'alzheimers'
...when I send the fetchObjects message to the data source.
So far so good. I notice that my adaptor returns two rows when data
Sources fetch loop calls my AdaptorChannel's fetchAttributes:withZone
method...
-fetchAttributes:withZone, returning row = {CUI = C0051532; DES =
alzheimers; }
-fetchAttributes:withZone, returning row = {CUI = C0105775; DES =
alzheimers; }
...notice the two CUI fields are in fact different. The
strangness occurs when I print the description of what's returned by the
data sources fetchObjects method... It returns the right number of
objects, but the objects all seems to be copies of the row returned by the
last call to fetchAttributes:withZone method...
Jul 11 13:52:54 [3855] keyRecs = (
{
entity = umls141;
self = "<EOGenericRecord: 0x13e474>";
values = {CUI = C0105775; DES = alzheimers; };
},
{
entity = umls141;
self = "<EOGenericRecord: 0x13e474>";
values = {CUI = C0105775; DES = alzheimers; };
}
)
...Any clues? Or should I work at the database level and set up
my own fetch loop since I know the adaptors returning all the right stuff?

Date: 11 Jul 1995 22:38:07 GMT
Organization: University of Illinois at Urbana
Message-ID: <3tuugf$4di@vixen.cso.uiuc.edu>
I'm attempting to write a SEGV signal handler under NS 3.0 (black) which
needs to be aware of 3 things:
1) The address that caused the fault
2) The type of operation (read or write)
3) The data and size of access
Also, it appears to me that when the SEGV handler exits, read operations will
re-start, but writes will not.
So here are my questions:
1) Can I get all of the above info inside the handler, or will I
have to intall my own fault handler in the process' Access
Fault vector?
2) How can I make write operations re-start from the SEGV handler
without doing something hackish like modifying the PC?
3) If I do have to install my own Access Fault routine, how do I do
this, and can anybody provide me with sample 68040 code?
4) Am I even on the right track?
GDB has to be able to do this, because it gets the access address right every
time. If anybody could help me with this, I would be most grateful.
E-mail responses would be best for me, I'll summarize if there is interest.

While people debate the merits of ObjectiveC vs C++, I'd
like to concentrate on the GUI-builder question for a bit.
First thing to realize is that InterfaceBuilder is *not* a GUI
builder. That happens to be it's most popular use, but the key to
InterfaceBuilder is that it's not just another program to create
code that implements GUI elements.
The interface builder archives and manipulates objects. It does
not produce code. Most GUI builders I've seen just spit out code
-- and usually that's code which you would go on to modify. The
problem comes up when you then go back to make some changes to the
GUI itself. You can't feed your current code back into the GUI
builder and modify it. You either modify your code (by hand,
dumping the GUI builder), or you use the GUI builder to punch out
a new chunk of code (which you then try to merge with your earlier
code).
The fact that InterfaceBuilder is for archiving and manipulating
objects is really the key to the whole debate. Once you grasp
that, you realize that it could be used to manipulate *any* kind
of object -- it's not limited to GUI-related things.
It's my guess that ObjectiveC makes it easier to write something
like InterfaceBuilder than C++ would make it, so maybe one could
approach that debate from the standpoint of "what language makes
InterfaceBuilder easy?". Me, I just don't like C++, so that debate
doesn't interest me. Most the programmers I know regularly refer
to it as C--, to give you an idea of how "highly" it's valued.
The problem with debating languages is that it often boils down to
one person saying "Oh yeah? Well I wrote a 100,000 line program
in this language and eventually got it working, so the language
must be good". And since every language has someone who can say
that, the debate just goes round and round.

If you mean static analysis for purposes of generating optimized code, then I
suppose you are correct.
If instead, you mean static analysis for purposes of detecting programming
errors during compilation, then I think you unfairly malign Objective-C.
If you carefully assign types to arguments and return values in Objective-C,
then the compiler can and will detect most mismatches at compile time. If
instead you let them default to id, the compiler does little to check what
you type.
Its quite analogous to C IMHO. If you invest the time to define the types in
function prototypes, the compiler will catch many type mismatches. If you
don't make proper protypes (or just type things to void *), you get no help
from the compiler. The choice is yours.
Unfortunately, quite a lot of Objective-C code takes the second approach -
such as the appkit. Fortunately, OPENSTEP corrects that error.

I don't really know about Intel NextStep systems (I use black hardware :) but I heard

misconfigured system and/or was the reason. The same happened to me for a while.
I found out it was caused by a malfunctioning SIMM.
Better check your RAM/cache configuration.

This is a little off point, but my guess, and I think I've seen this
hammered to death elsewhere, is that C++ is so prevelent because it was
free. You had to pay for Objective-C so no one wanted to use it and C++
became the standard. But like most things, you get what you pay for :)

Operator overloading is easy to abuse, but there are cases where the
alternative can obscure meaning as well.
If I write some objects for complex number arithmetic for instance, it's
nicer to write:
z3 = (z1 + z2)*z4;
Than something more ghastly like:
[[[z3 addTo:z1] addTo: z2] timesBy:z4];
For arithmetic and other naturally formulaic expressions, overloading can save
considerable annoyance. When overloading goes wrong is when some buttwipe
starts writing things like:
Screen += (Window += Button);
To create a new Window and the like. But operators that are inherently
arithmetic, I don't mind overloading, as long as the overloaded meanings
correspond to sensibly arithmetic things.
It's almost as trendy to bash C++ and everything about it as it is trendy
to fall prostrate before it, sluicing out sycophantic praise for it and
everything about it. Recognizing that it sucks, but realizing that there
are occasional aspects of it that aren't totally ill-conceived seems to
be worth doing.

the problem is that using types (i.e. class names) effectively takes you
back to the static binding given by C++.
IMHO, object protocols are severely underused in Objective C. the
compiler should check protocol conformance more rigourously; anywhere
an object is used, it should be declared with a protocol matching its
usage.
this still allows strong type checking, but also retains the
flexibility that true dynamic binding gives you, because it doesn't
force the use of certain classes. it enhances modularity by keeping
knowledge of class information within the classes themselves, so one is
free to alter the class hierarchy without affecting the type checking.
a protocol also acts as a much better documentation of the interface
between objects than a class name, because it only contains those
methods which are essential to the objects' interaction. unlike a
class, which often implements (along with its superclasses) hundreds of
methods, only a few of which are relevant.
class based type checking is an anachronism in a dynamically binding
language.

No. Indicating the type of an object, whether by `id <SomeProtocol>' or by
`SomeClass *' only confines the search space of the compiler when it looks
for typing information of the arguments and the return value of a method.
In NeXT and GNU Objective-C, _all_ _method_ _invocations_ _are_
_dynamically_ _bound_ _period_.
IMHO, object protocols are severely underused in Objective C. the
compiler should check protocol conformance more rigourously;
The problem with protocols is that the compiler is too dumb for less obvious
use of protocols. For instance, how'd you declare a method which accepts as
an argument a class object which implements the class methods as declared in
a certain protocol? You can't. --Tiggr

It may be "nicer" but the meaning of the C++ statement is not necessarily
clear to me. The ObjC version may involve a bit more typing but it's
meaning is crystal clear (as defined by the manual).

Not exactly correct. It is possible to do method invocations that are
not dynamically bound in the sense we're talking about. If you'll be
calling the same method over and over in a tight loop, grab its
@selector, then call the function directly inside the loop. Since the
Obj-C runtime is "standardized" (whatever that means), this is usually
acceptable code. Pretty nasty, tho. 100,000 calls, but only one dynamic
lookup, translates into a lot of non-dynamically bound calls.

Here's the plain vanilla unix stuff. Up to you to wrap in an object.
struct passwd *pwd;

It's the only thing in the pw_gecos field of a passwd struct.
So:
const char *realNameForUsername(const char *username)
{
struct passwd *user = getpwnam((char *)username);
if (user) return user->pw_gecos;
return NULL; // if username was invalid
}
Hope this helps...

Date: 12 Jul 1995 22:06:18 GMT
Organization: University of Wisconsin, Madison
Message-ID: <3u1h0q$1hpe@news.doit.wisc.edu>
I posted recently about my problems interacting with a Unix SubProcess.
Since no one responded to it I thought I would add a bit more info and ask
an other question also. (Thanks much for all the help with the text field
to those that responded.)
I am trying to make a little front end for a telnet session, send it some
commands/strings when it gets connected, and then send further commands as
strings from a panel and text field box.
Hopeful series of events.
Invokes "/bin/sh" with the init: message in the class and with pty support.
Get connected.
Sends terminal type, VT100 in this case.
Sends a password.
Send further commands via Panel buttons.
I am using the Subprocess class documented in NextDeveloper/Examples/UNIX/.
I get connected but only partially. When it connects it seems that the
connection gets dropped due to "lack of input" because I get the
"Connection dropped by foreign host message". If I go through Terminal I
get connected and get the text that asks me for the Terminal type and
passwd string. Everything then goes as smooth as it normally does.
I have tried different shells, sourcing startup files, and tn3270 instead
of telnet. I then tried telnetting to my own machine when I noticed that
things didn't work as well in the terminal window.
What is the difference? I know that is a big thing to ask but by starting
sh in a scrollview, the one enclosed with the subprocess for instance,
instead of the terminal is what seems to be throwing me off. Either that or
the subprocess is not doing exactly what Terminal does.
I could scrap all of this if there was a way to send commands to a terminal
window from a panel. Like the GDB panel invoked via Project Builder.app.
You click debug, it chucks up a terminal, sends it a command, and then
looks to the panel for more input. Any one know how to pull that one off?
Thanks for any help or even starting places to look.

Probably I am missng something here, but this really isn't an issue of
'cyclic references', is it? It seems to me the problem is that NeXT has
introduced a good new low tech paradigm for dealing with garbage collection.
Unfortunately, not all their classes make use of this. If the button, in
the above example, did retain the DocumentController (as I suspect it
should) and then released it (and all other relevant instance variables)
when it, itself, was freed/released, then this situation would not be bad.
Thus: I don't think it is circularity, it is having two memory
allocation/deallocation schemes coexisting (the older one not knowing about
retain and release as it should).
Agreements or Disagreements?

I believe this is a potential problem, because the terminal produced with

Again, the terminal produced by the subprocess example does not recognize

Ah, you want magic. Luckily, with UNIX there usually is a way. You can
have your app launch a UNIX tool to act as a frontend (usign pty's) for
your UNIX process and simultaneously have it act as a rearend for a
Terminal.app shell window. You can then avail and control this tool from
your app through the distributed objects mechanism or Mach RPC.
Simple huh?
In case you are wondering. I have written the above which is a
Multi-tasked, Multi-threaded tool which acts as frontend to both sides of
tip and which acts as a rearend to Terminal.app. I must, however, warn
you that although this tool is not very big it is a rather tricky piece of
code. If you are interested let me know and I will send you a Beta source
version of my app.
It would be nice if their was a simpler interface to Terminal.app (there
may be), but the nice thing about the UNIX way is it's inherent
portability

Not exactly correct. It is possible to do method invocations that are
not dynamically bound in the sense we're talking about. If you'll be

Yes, you can get a function pointer by a runtime lookup (i.e. dynamic
binding). And then you invoke functions. Which are not methods. And thus
the following statement remains correct: In NeXT and GNU Objective-C, _all_
_method_ _invocations_ _are_ _dynamically_ _bound_ _period_. --Tiggr

Well, one thing C++ tried to do was add ideas taken from a variety
of sources. This was done precisely to make it attractive to as
many people as possible. It explains both why it's so popular,
and why it's so full of "unclear on the concept". It's not a
concept-driven design, so there is no clear concept.
Given a language with a clear and focused concept, programmers
have to adapt to it. C++ tried to adapt itself to the pool of
potential programmers.

I have to second that.
Operator overloading causes C++ to be a complete nightmare - you _don't_ get
the benefit of dynamic binding, but you pay the penalty of not being able to
do good static analysis of the code!
As for dynamic binding vs. performance - is it really that hard to do
@selector before entering a tight loop? Because if you cover those cases,
the extra time spent for the dynamic binding in the rest of the code is
mostly noise. It's certainly small enough to be easily made up by having a
better code optimizer.
Naw, C++ is so full of "unclear on the concept" or language design that it's
stunning that it's made it as far as it has.

As for dynamic binding vs. performance - is it really that hard to do
@selector before entering a tight loop? Because if you cover those cases,
the extra time spent for the dynamic binding in the rest of the code is
mostly noise. It's certainly small enough to be easily made up by having a
better code optimizer.
Naw, C++ is so full of "unclear on the concept" of language design that it's
stunning that it's made it as far as it has.

I agree - 0 _would_ be a valid fd if stdin has been closed. But if you try to

I know. I got this ERRNO and it's ok. But this 0-fd usually just occurred when
lots of threads ran and lots of ports died - so I assumed these facts

I think you come pretty far by adding '-posix' to CFLAGS and LDFLAGS (sp?). Nevertheless there still remain some minor pitfalls in the compilation (have to look them up).
On the other hand, I'm not sure if it makes sense to use '-posix' for
ncurses. I think this means that you have to use '-posix' for any
application that you'll compile with ncurses, and this may result in
some trouble. It may be a better way to implement the changes that are
necessary to compile ncurses for NEXTSTEP without '-posix'.

You can load the nib file in a special NXZone and free the zone when your
are over with the nib content.
This almost work, the only problem is when you have pointers to objet in
the nib. The classic case is the application windowList that contains
pointers to Windows within the list. Beware of the fact that popup are
windows and so can be present in the windowList (I had the problem once).
So you can have your file owner free the window that are present in the
nib and after deallocate the whole nib.
Hope that helps.

I have an ISDN/PPP internet connection via an Ascend Pipeline 50 with an
IP address of 198.3.189.1
My goal is to have every other NeXT machine (198.3.189.xxx) on the
network see the Pipe 50 and point to 198.3.189.1 when looking for a
connection upon invoking a WWW browser or such.
How do I do this?
I thought I simply needed to set the default gateway in SNMP to be
198.3.189.1 for each NeXT machine on the network. However, even when I
do this, each time I startup OmniWeb it cannot find the connection.
What am I doing wrong?
I did not see anywhere from within the OmniWeb app to point to the
gateway. I believe OmniWeb assumes the connection has already been
established.
Also, since the PPP is running on the Pipe 50 only, is there anyway I can
establish the Pipe 50's PPP connection from one of my workstations
instead of having to do it from the Pipe 50 itself?

That is exactly what I meant. Is it not a pity? Why cannot IB be smart enough to correctly modify the appropriate
header and implementation files? This to me would be the natural way to go.
And since we are at it: let IB offer the implementation/modification of the code for a selected method in a TextView
(or your favourite editor). What do I care if/whether I cross file boundaries or how else things are organized
internally?
I work with objects - thanks to the hype. So give me true object manipulation facilities, not some editing crap which
balks on modifications i.e. chews up my work. SmallTalk implementations do allow for method code modification in their
browsers.
Should not be impossible to do for NEXT with a little help from find/grep/cut/patch/diff etc.

If you enjoy beating your head against brick walls, you might enjoy
freeing nib objects by freeing their zone :-) I've *NEVER* gotten this to
work with any real nibs (maybe with some toy examples). And forget it if
you've got any DBModules in the nib. You can *NEVER* free a DBModule
without your app subsequently crashing.
Because so many classes need to do proper cleanup that's implemented
in their free methods, just blowing away their memory by freeing their
zone deprives them of the opportunity for proper cleanup. This results in
all sorts of mysterious problems.
So since you must free objects so they can clean up properly, you
don't really need to blow away their zone. All nib objects are accessible
in some way (you wouldn't be creating unaccessible nib objects, would
you?), so just accesss and free them when no longer needed.

Not to mention that this trick won't work in OpenStep, there is no
NSDestroyZone, instead NSRecycleZone, which just moves the zone's memory
back into the default zone.

I don't think that switch works anymore. Anyway, someone should give
NeXT a good boot in the head and have them do their BFD backend for
MachO. It would make life easy for the rest of us... just imagine, up to
date gdb binaries as you need them, etc.
As is, NeXT's MachO support in the GNU bin tools is a horrible kludge.
And, the source that they ship on the CD-ROM doesn't even compile. What
a waste... you should just skip using NEXTSTEP now and go straight to
Linux.

Summary: gdb on i486 doesn't print floats properly
Keywords: gdb
GDB won't print proper results for messages or functions that return
double or float on i486 boxes.
Example
main.c:
double foo(int x)
{
return (double)x*5.0;
}
int main() {
double a;
printf ("%g\n",foo(5.0));
return 0;
}
When you compile and run this code it works fine. But if you debug it in
gdb and explicitly call foo, you won't get the correct value returned to you.
(gdb) p a = foo(10.0)
a will not be equal to 50.00.
In the cc Man page there are several options for i486 floating point
arithmetic.
These `-m' options are defined for the Intel 80386 family of
computers:
-m486
-mno-486
Control whether or not code is optimized for a 486 in-
stead of an 386. Code generated for a 486 will run on
a 386 and vice versa.
-msoft-float
Generate output containing library calls for floating
point. Warning: the requisite libraries are not part
of the GNU C compiler. Normally the facilities of the
machine's usual C compiler are used, but this can't be
done directly in cross-compilation. You must make your
own arrangements to provide suitable library functions
for cross-compilation.
On machines where a function returns floating point
results in the 80387 register stack, some floating
point opcodes may be emitted even if `-msoft-float' is
used.
-mno-fp-ret-in-387
Do not use the FPU registers for return values of func-
tions.
The usual calling convention has functions return
values of types float and double in an FPU register,
even if there is no FPU. The idea is that the operat-
ing system should emulate an FPU.
The option `-mno-fp-ret-in-387' causes such values to
be returned in ordinary CPU registers instead.
I've tried debugging code with the the option, `-mno-fp-ret-in-387'. But
this does not seem to help. Does anyone know of a workaround for this
problem?
Thanks,

Although I agree with you for most intents and purposes, there are circumstances
where it is _necessary_ to use IB to add actions or outlets. This arises when the
object in question doesn't actually implement the actions or outlets, but passes
unrecognized messages on to a delegate. Thus the action (or outlet, assuming
-setFoo: is implemented somewhere) can be linked to other objects even though it
doesn't appear in the object's .h file.

I've never understood why IB insists on outlets being typeless. It would be simple to
parse the type in the .h file and require that any links to the outlets meet the type
requirements.

subprocess and piping the input and output to and fro a ScrollView?
Any help appreciated.
Torrey McMahon
P.S.
For those interested:
I have posted a bit about my problem with this before. Look for
"Subprocess" in the header or my name even!
But to sum up....
I have tried stty settings. And they are both the same in each. I have
tried sourcing the shell startup files and the .login files. But something
is blocking my attempts at programming this bugger. The same thing happens
when I use the Telnet.app found on the archives so it is doing the same
thing I am and having the same problem. I am using the Subprocess example
from NeXT for a framework.

Point default at the P50; that should do it nicely. If the unit is set up
with the proper SPIDs and all, it will call by itself when there is traffic
for it.
Note that your provider must know about the P50 and where it is supposed
to be address-wise.

Is the P50 pointing default at the other end of the connection?

The P50 should come online automatically when there is traffic for the
network link. There is no need to manually connect it.

Hrm. I'm afraid I don't quite follow what you're saying here.
While I agree that IB isn't as smart as it could be, I still say
it's a lot better than traditional GUI-builders I've seen. If I
understand the problem you're talking about, I still don't see how
it could possibly be considered "the exact same thing" as the
lameness of standard GUI builders. I realize you can't "unparse"
in IB after you've made changes to your header files, but at
least you can make changes to the header files and keep IB in
sync via "parse".

I believe you mean "UnParse" there. Parse works fine. I agree
that UnParse is only useful for the very initial stage of making
an object (or a class, really).

Most of my NeXTSTEP programming is pretty simple stuff, so there
are a lot of things I haven't really used much. I still think IB
is *significant* because it's archiving and manipulating objects,
and not just spitting out code for some compiler. Whether people
take advantage of that is another question...
The first half of the Objective-C book by Brad Cox is sort of the
philosophical underpinnings of what he expects from Object Oriented
programming. Namely, "software IC"s. While the hardware side of
the computer industry continues to progress at a rapid rate, the
software side is (relatively speaking) going nowhere. We're all
sitting around rewriting the same damn thing we were writing 20
years ago. As long as we're always writing everything from scratch,
it's always going to be the hardware guys who are making us look
good, because we'll be do damn stupid to make any significant
progress ourselves.
It is my guess that for software IC's to *really* work, you need
something like InterfaceBuilder. Something where you can manipulate
an object without any religious affilation to the language it
happens to be written in. Standard GUI builders do *nothing* to
divorce objects from a language. IB does something, although it
doesn't do as much as I'd like. Still, you have to start somewhere,
and I'd rather start with InterfaceBuilder which is dealing at the
object level, than some lame GUI-builder which is really just a
pretty layer on top of the same old programming languages.
Now, I should admit here that IB isn't the only tool that's
trying to divorce programming from the standard programming
language paradigm. It's just the one that interests me the most.

My main reason for commenting (even though I haven't done a lot
of in-depth NeXTSTEP programming) is that I thought your question
on IB vs GUI-builders was a lot more interesting than another
age-old debate over which language is more macho than the other.
As long as all objects have to be written in any one single
language, we're going to continue to rewrite the same old crap
over and over, without really making any progress.

Sadly, I feel the goal of maintaining references cannot be correctly
achieved.
Silly example:
Should an browser retain it delegate ?
NO: A browser cannot live without its delegate. The delegate can be
thought as a Controller, and have the total control of the browser. So the
delegate is responsible of freeing the browser.
YES: A browser is the main interface element, and I have a lightweight
delegate (ie a NSArray of string) that fills the delegate. When the window
which own the browser is freed, the NSArray should be deallocated with the
browser.
(Note that I consider the two paradigm beeing equally valid, and
argumentation for one or the other could last quite long - If anybody
choose to say that only one is valid, I'll fight to death defending the
alternative :-) )
The problem is that we have to find a partial order through the 'pointers'
graph, and use that order to affect ownership. Can we say that a
browser<delegate or the opposite ?
I'm afraid that depends of the class of the delegate. If the delegate is a
NSArray, we have browser > delegate, but if the delegate is the main
controller of the app, I want to have delegate > browser. (Think of '>' to
be 'more important' and impling 'should retain')
So, what happends if you use two objects that comes from two different
vendors that to not agree about the partial ordering ?
Imagine I give you a nice interface object that retains its delegate and
you want to have your appController be its delegate ?
Imagine I give you a nice interface object that could work nicely with a
NSDictionary for delegate, but don't retain it ?
Do you really want to use a '- setDelegate:aDelegate
andRetain:(BOOL)retainFlag' mnethod ?
The solution was named Garbage Collection and was missed.
Dead End.

Of course -init is not invoked. -init sets up a default state, but archived
objects file are individually configuerd in IB (Inspector panel).
Exception: instantiated objects are initialized using -init when the ".nib"
file is loaded.
If you drag an object from a palette it is written on a stream an read back
after dropping somewhere.
By the way, why didn't you just insert some printf() in your -init method and
test it yourself?

IB merely parses the interface file looking for "id" and "sender" and
considers the "id" variables to be outlets and methods with a "sender"
argument to be actions.
So the above approach keeps IB happy yet uses static typing at
run-time when __STDC__ (a standard ANSI C macro) is defined.

Suleman,
I used to work for CitiBank and I can tell you that there is no consistent
algorithm. Different banks use different "check digit" algorithms. Even
CitiBank had different algorithms for MasterCard and VISA and different
algorithms for different version of the MasterCard (initially 12 digits,
then 16 digits). Also, this is supposed to be "secret" and I can not tell
you what I used when I was there (or they could sue me for breach of
contract).

Oh, piffle. For all the credit cards that my company deals with (MasterCard,
Visa, Discover, and our private label card), you simply do a mod-10 sum over
all digits and compare it to the last (check) digit. Nothing secret about it.
It's possible that there are more sophisticated algorithms out there, but I
don't think that's what he wants. Our production code is enclosed below.

There may not be a "consistent" one, but there certainly is either a "weak"

definitely refuses to dial if the number entered doesn't seem valid to it.
Once it believes in validity, then it dials to check reality and chargeability.

I've discovered a bug when I compile programs Quad fat under
3.3/Dev3.3. It doesn't cause a problem in the m68k binary, but it does
in the i386 (don't know about hppa or sparc).
The contents of the memory that self points to are getting set to zero
after I enter a loop.
defaultRun = malloc(sizeof(NXRun));
defaultRun->font = aFont;
defaultRun->chars = 0;
style = malloc(sizeof(NXTextStyle));
style->indent1st = 0;
style->indent2nd = 0;
style->lineHt = [defaultRun->font pointSize] + 1;
style->descentLine = 2;
style->alignment = NX_LEFTALIGNED;
style->numTabs = 10;
style->tabs = malloc((style->numTabs * 2) * sizeof(NXTabStop));
/* Things are fine here
(gdb) print *self
$7 = {
isa = 0x625a0,
theText = 0x0,
theRuns = 0x0,
runStack = 0x0,
defaultRun = 0x470ea0
}
*/
width = [defaultRun->font getWidthOf:TABWIDTH];
for (i = 0; i < style->numTabs; i++) {
style->tabs[i].kind = NX_LEFTTAB;
style->tabs[i].x = (int) (width * (i + 1));
/* Self is wiped right here after the first time through
(gdb) print *self
$8 = {
isa = 0x0,
theText = 0x0,
theRuns = 0x0,
runStack = 0x0,
defaultRun = 0x0
}
*/
}
I haven't seen this problem when compiling for only i386 and m68k, but
when I throw in the hppa and sparc, this problem occurs.

I'm trying to generate an editable form on the screen. I'm using Text
objects rather than TextFields because some of the fields span
multiple lines. Everything has to be transparent so that the
background of the form shows through the Text objects.
The problem is that when I call something like:
[[fooText setText: "new text here"] display];
to change the contents of the Text, the Text object just overwrites
whatever was on the screen before. I want it to undraw itself before
redrawing the new text. Anyone have any ideas about this?

Is there any need to use __STDC__? Using any undefined macro definition
works fine for this purpose. Parsing the header-files Interface Builder
ignores any preprocessor directives anyway. So you can write interface
definitions like this:
#undef __INTERFACE_BUILDER__ // usually this macro is undef'ed
@interface MyObject:Object
{
#ifdef __INTERFACE_BUILDER__
id textField;
#else
TextField * textField;
#endif
}
@end

Hi
I am beginning developing with EOF and mSQL as DataBase. I take a look
on the NeXT examples, especially AccessLayer.
I choose the Database level approach to connect and select objects.
My question is :
How can we access the values inside the EOGenericRecord once you have
the objects.
For example I would like to get values for the following fields :
Name, address...
The only thing I can do is printing the object description with :
printf("%s\n",[[(NSString*)object description]cString]);
(object is a EOGenericRecord).
My program fetchs values and computes, it does not use UI objects.
Perhaps the solution is trivial, but I didn't find (YET) a pointer to
the right documentation or an example performing what I need.
If you have pieces of code, examples or pointers I will be very
grateful.
Thanks in advance :-)

Hmm. But if you do this, doesn't that mean that IB's image of
that class no longer matches the real class definition? Isn't
this a "Bad Thing"? Is there some change that should be made
to interface builder which would allow you to do things like
this, but which wouldn't result in you setting up IB to use a
false definition for the class?

Organization: Humboldt University Berlin, Department of Computer Science
Message-ID: <3ulrd5$ora@hahn.informatik.hu-berlin.de>
I want to create temporary rectangles in a view. For this reason I
have done the following:
1. create an NXImage with an appropriate size by
image = [ [NXImage alloc] init];
[image setSize: &aSize];
[image setFlipped: YES]; // because my view is flipped
[image setBackgroundColor: NX_COLORCLEAR];
2. draw a rectangle by
[image lockFocus];
PSnewpath();
PSmoveto(0.0, 0.0);
PSlineto(...); // and so on
PSsetgray(NX_BLACK);
PSstroke();
[image unlockFocus];
3. composite the image by
[view lockFocus];
[image composite: NX_XOR toPoint: &aPoint];
[view unlockFocus];
Step 3 has to be executed multiple times. Unfortunately, all I get
the first time is a completely black rectangle (and all odd times too).
All even times my drawn rectangle (black lines on a white background)
appears.
The former contents in the part of the view is lost.
Does anyone have any solutions for this problem?
Thanks, Oliver

one of the things i find minorly annoying is that IB has no way of
distinguishing between normal instance variables and outlets when
parsing a header file. which means that if you parse the header
file every time you add a new outlet or action, it adds all the
non-outlet instance variables as outlets.
i like to be able to check that all my connections are made my
just looking at the connections inspector and making sure all the
outlets have their round dots attached.
why couldn't NeXT have defined an 'Outlet' type
(typedef id Outlet) and then parse for these ? This would make
it explicit both to IB and to people reading the header file
which instance variables are outlets (i.e. pre-initialised) and which
are not (need initialisation in code).
e.g.
@interface MyObject : Object
{
Outlet outlet1;
Outlet outlet2;
id current_selection;
}
it also bugs me that they couldn't be bothered to write a decent C
parser - it doesn't even understand syntax like :
id x, y, z;
let alone
id fields[5];
which is a pity as there are many occasions when there are several
outlets that the code wishes to access homogenously rather than individually.
on an unrelated note, does anyone know of a decent way of setting the
typeface of a load of textfields contained in separate boxes ?
currently it seems _extremely_ laborious (select the field, find the
font and fontsize, set it, select another field (losing the font you've
just found), find the font again, etc, etc)
it works fine for a multiple selection of fields on the same level -
but there doesn't seem to be a way of selecting multiple objects within
multiple boxes.

I'm *sure* I'm missing something really obvious here, but I can't
figure it out, so I turn to you folks. I appreciate any help you can
give me on this.
I have a two column browser displaying 2 levels (only) of heirarchical
data. I have top-level objects that I can create and display in
column zero of my NXBrowser. When I create and destroy these objects
I update my browser by sending a -reloadColumn:0 to the browser. Fine
and dandy.
However, some of the top-level objects may have zero or many secondary
objects associated with them, and I'd like to list these objects in
column 1 of the browser. If I create a top-level object with zero
secondary objects, I set the cell in column zero to be a Leaf, thus it
gets no arrow and nothing shows up in column one.
The problem comes when I add the first secondary object to a top-level
object (i.e. the selected cell in column 0 of the browser). I cannot
figure out how to get column 1 updated when the first object in that
column is added. I can set the column zero selected cell to non-leaf,
and I see the arrow show up, but there doesn't seem to be a what to
programmatically get column 1 loaded. I can re-click the mouse on the
column zero selected cell, and watch as my (normal) delegate receives
a -[browser:fillMatrix:inColumn:] message (where I load column one as
expected). But I just can't find a way to get
-[browser:fillMatrix:inColumn:] to be called programmatically. It
seems that I'm not allowed to call -[NXBrowser addColumn], which I
tried ;), but that caused all sorts of badness. I tried calling
-[Matrix selectCell:] on the matrix in column zero, but that didn't do
the trick. I tried various combinations of displayColumn: and
friends, again with no luck.
Does anybody know how to do this?
Oh and in a related topic, what are the NXBrowser delegate methods
browser:columnIsValid: and browser:selectCell:inColumn: typically used
for?
Thanks in advance.

Since working a little with C++ I have developed the habit of beginning
private instance variables with an underscore, i.e.,
id _foo;
IB will not add _foo as an outlet when parsing the header file.

What's the relationship (if any) between a NXStream and a
"C" FILE * type. Given one, is there anyway to convert to
the other.
Actually, for portability reasons the functionality I'm really
looking for is something like a log window. Basically a ScollView

Hi. I'm running 3.3 and I have this problem. Drag and drop

have a subclass of view in whihc I over-ride the dragging

a file is dragged over the view, verything works perfectly.
The secon (and third and ...) times, prepareForDragOperation
gets called, I return a YES (in fact, that's what the method
does-- it's very very simple) and then performDragOperation
is never called (verified through debugger and printf's).
This, of course, directly contradicts the manuals.
Has this ever happened to anyone ? Does anybody have

I had a similar problem when using the NXBrowser object and found
that I could force the Browser to update on demand by using the
-setPath: method whenever I added a new secondary object (i.e., made
a new path...)
The documentation describes how to use the -setPath: method pretty
well. However, it doesn't indicate that it's useful for forcing updates
although the last paragraph in the description hints at it:
Your code should never try to set a path or select items by
sending Cell selection messages to the Matrices in the
NXBrowser's columns. This bypasses every mechanism that allows
the NXBrowser to update its display and load columns and
Cells properly.
Hope that helps.

I am in the process of setting up a WWW server under NS 3.3 on black
hardware. I would like to set up the Apache server to serve multiple
domains. In order for this to work however, ifconfig must support
the alias option. NS 3.3 does not appear to do this.
Does anyone have the source code for ifconfig with the alias option
available or even compiled for the NeXT. I know that bsdi v2.0 supports
the alias option. It strikes me that the source should be available
from someone and that it would be fairly straightforward to compile.
I would appreciate any help on this and I will post the results and/or
a copy of ifconfig with the alias option if I can come up with it.I
have to believe that others are having the same problem. Certainly
anyone wanting to put up a web site under NS is going to confront
this problem.

I have an EOF application that has RTF description fields in many of the
tables. I'm storing them as BLOBs in my QuickBase database, and the
EOModel brings them in as NSStrings.
The Window has both the contents of a record, and a table of all the
records. I have connected both the TextFields/ScrollViews and the
NXTableVectors to the same EOController, so that clicking on a record in
the table auto-updates the text boxes.
The problem is with the RTF fields; they look fine in a ScrollView, but
not in the NXTableView, which doesn't understand RTF. So, the user is
treated to the guts of the RTF code.
Is there an easy/efficient way of having the Table interpret the RTF? Or,
alternatively, is there an easy way of having the table ASCII-ize the
field before displaying it?
It's EOF 1.1, with NSDev 3.3.

It isn't really _necessary_ to use IB for this purpose as long as you
rely on its "feature" to ignore any preprocessor directives. So it is
possible to write a method-definition in your header file, that allows
you to drag connections within IB after parsing the header file, but
doesn't lead to any 'incomplete implementation'-warning when you are
compiling your class. For example:
#if 0
- setFoo:sender;
#endif

Since one of the reasons to *have* credit card verification

banks wouldn't want to give that info out. Certainly not
posting the information all over usenet.

Why not do it yourself, or the inverse of it that is. Do a
typedef id internalID
and then use "internalID" to define all the non-outlets?
Or define non-outlets as specific types, instead of generic
ID's (ie, "Window *myWindow;" instead of "id myWindow").

Hmm. Does "command-3" and "command-4" work for copying font

Sorry, I meant to say I was referring to your prior statement that IB is good to begin with but is of no/less use when
it comes to modifying because 'UnParse' is not intelligent. Like you stated, you have to edit the source files, add
things there and 'Parse' the modifications in IB.
This I consider bad:
using IB to design your object space with its classes, instances, actions and outlets together with the visible parts
of the GUI is great. But once you need to alter an app (which is the natural way in most cases) you loose the initial
advantage of dealing with your objects in IB, because it cannot properly UnParse-Merge! Instead you are forced to '70s
technology of adding things with an editor - remember, the same things IB allows to enter and for which it was
designed.
This forces on me an inconsistent developmewnt scheme :
start with IB, from then on, you are on your own.
Considering this, I find the media hype NeXT got for its sophisticated development tools unjustified.

Brian,
Thanks very much, setting the path did indeed make it all work! I
knew it had to be something I'd overlooked. I appreciate the tip.
To NeXT, if you're listening. It seems kind of bogus and obscure that
the only way to get subsequent columns loaded is by doing a setPath:.
For example, it seems to imply that I have to reserve a character in
the cell stringValues for the pathSeparator (haven't tried a
non-printable character, so maybe that will work?). Still, while I
understand that NXBrowsers may have been primarily used for file
system path displays, a more general API would be better. NXBrowsers
are useful things! :-)

I usually call addColumn after having selected ONE non-leaf cell in the

do this on many levels without any problems.

One way would be to install a custom NXTextFormatter subclass in the
tableVectors that need to display RTF. This textFormatter would enlist
that aid of an unbordered textFieldCell to interpret and draw the RTF text
at the proper coordinates of the tableVector. This involves overriding

Message-ID: <3up4l7$8hg@nntp.crl.com>
I've been using an i860 vector accelerator on a Concurrent system (68030)
for some power spectra computations. This mahine is a data acq machine
and is no always available. That VA came with SAL (Scientific Algorithm
Library). We've had a NeXT cube (black 68040) sitting around for a
while, mainly acting as a print/dialin server. I just came across the
fact that it contains a Motorola 56k (is it a 56001?) chip and some
routines for accessing it. I set about converting the the SAL calls to
the 60 or so calls that were in the 56k's array processing library. I
thought I could make do with that limited set of calls but no go. Some
calls are missing, but more importantly the FFT function provided won't
seem to handle more than 1024 points. I need to do FFTs with 16k
(possibly 32k) points (real to complex).
Is there a version of SAL available for the NeXT040/56k combination? Do
I have some other options, short of compiling up my own routines? (I
think the compiling might go OK, but the interfacing to the calls from
the host CPU scares me a bit). I'm just a C programmer and though I have
the current56k FFT routine (fftr2a) source I can't immediately see where
to tweak it to up the allowed number of points.
Thanks for any tips/pointers,

Well, the code you posted is a bit more complex than that, but the
code seems to work and the "simple mod-10 sum" doesn't, so perhaps the
code should be better explained. Here's what I'm seeing:
The code is doing a sum across all digits *except* the last one, which
serves as a check digit. The 2nd, 4th, 6th, ... (even positioned)
digits are passed into the sum unchanged, whereas the odd positioned
digits are instead passed in according to the mapping:
0 -> 0 5 -> 1
1 -> 2 6 -> 3
2 -> 4 7 -> 5
3 -> 6 8 -> 7
4 -> 8 9 -> 9
(this is effectively what you get by doubling the digit and then
adding the digits in the sum of the result).
At this point, you then do a modulo-10 sum, and subtract the result
from 10 to get the final check digit.
So, if you had the credit card number 1234 5678 2315 8393 (and yes,
I'm making this number up), you'd add together the digits
2+2+6+4 + 1+6+5+8 + 4+3+2+5 + 7+3+9 = 7 (mod 10)
If you then subtract this result from 10, you get 3, which is the
value of the check digit.
The interesting thing is that this algorithm returns a 1 (check is
good) for most of the cards in my wallet, including all credit cards,
as well as my bank card, a cafeteria credit card used by my workplace,
and a department store card. Of course, some of these may just be a
coincidence (after all, 10% of all random numbers will pass this
check), but it is intriguing...

I suspect you've exceeded the default stack size. I don't know what
that size is and I'll be late for dinner if I try to find it :-)
If you malloc heap space for large arrays, the seg fault may not
occur.

Subject: HELP! Sound will not record except from CODEC
Date: 22 Jul 1995 02:43:09 GMT
Organization: Express Access Online Communications, USA
Message-ID: <3upojt$jta@news4.digex.net>
I cannot get sound to record from anything other than the CODEC. :-( I
cannot figure out what is wrong. I've tried both the Sound class and the
sound functions to no avail.
However, if I simply substitute the data_format/sampling_rates for the
CODEC instead of the higher quality settings for the DSP, then my routines
work. BTW, I am using this on a NeXTdimension (even though I eventually
will use Intel with an i56 card) so I should be able to record at the
higher rates!?!
I have 3 methods (if you can call them that, they are really just a few
lines of code) and everything seems to work fine UNTIL I try to convert the
sound from DSP format into LINEAR (so I will be able to play it).
As soon as the convertToFormat line gets executed, the program bombs! Any
ideas will be greatly appreciated; I didn't think this would present such
problems and find myself in a tight bind confronting an upcoming
deadline... Below are the three methods that should do all the work. I
just want to record at 22khz @ 16bit, stop the recording and them play...
//I defined myNewSound as type id in the header...
- myRecord:sender
{
myNewSound = [Sound new];
[myNewSound setDelegate:self];
[myNewSound setDataSize:1000000
dataFormat: SND_FORMAT_DSP_DATA_16
//if I make these 8bit mulaw, and codec sample
//rate, everything works fine...
//of course if I sample from the codec I don't
//need to do the dataFormat conversion below in
//the myStop method...
samplingRate: SND_RATE_LOW
channelCount:1
infoSize:0 ];
[myNewSound record];
return self;
}
- myStop:sender
{
[myNewSound stop:self];
[myNewSound convertToFormat:SND_FORMAT_LINEAR_16]; //bombs here???
return self;
}
- myPlay:sender
{
[myNewSound play:self];
return self;
}

No, this is a hardware limitation: you won't be able to record anything
other than mu-law encoded sounds at CODEC sampling rate with NeXT hardware
unless you add on an expernal A/D box (such as the Singular Solutions AD64x
or DigitalEars).

This is wrong: you shouldn't be recording as DSP data... you should specify
a SND format, e.g. SND_FORMAT_MULAW_8
To do this sort of thing "as well as possible", you should find out what
formats and sampling rates are supported by your hardware, something along
the lines of:
sd = [[NXSoundIn alloc] init];
if ([sd acceptsContinuousStreamSamplingRates])
{
float lowRate, highRate;
[sd getStreamSamplingRatesLow:&lowRate high:&highRate];
if ((highRate >= ABBOT_SAMP_RATE) && (lowRate <= ABBOT_SAMP_RATE))
{
}
else
{
sstruct.samplingRate = highRate;
}
}
else
{
const float *rates;
float rate;
unsigned int numRate, i;
[sd getStreamSamplingRates:&rates count:&numRate];
rate = rates[0];
if (rate != ABBOT_SAMP_RATE)
{
for (i = 1; i < numRate; i++)
{
if (rates[i] > rate)
{
rate = rates[i];
}
if (rates[i] == ABBOT_SAMP_RATE)
{
break;
}
}
}
sstruct.samplingRate = rate;
// This check's here as otherwise CODEC rate
// isn't recognised... <sigh>
if ((rate >= SND_RATE_CODEC -1) &&
(rate <= SND_RATE_CODEC +1))
{
sstruct.samplingRate = SND_RATE_CODEC;
sstruct.dataFormat = SND_FORMAT_MULAW_8;
}
}
I'm sure there's a more elegant way of doing this, but I hope you get the
idea.
Have fun,

Okay, I admit I glossed over the details of the algorithm; perhaps it should
be "mod-10 sum over mangled sum of all significant card digits" (The check
digit and prefixes for private labels aren't significant). Stephen's
detailed analysis of the algorithm is correct. There is also some more
checking that can be done (such as the verifying that the starting digit of
all VISA cards is 4, and MC cards start in the range is 501 or 51-55, etc).
Sean is right as well - the purpose of this algorithm is really to catch
transposed digits, typos, or obvious fakes. Once it passes this simple check,
_then_ we pass card number, amount and expiration date to our authorizer who
checks the customer's credit limit, and gives us an approval or decline
response. It's faster to catch typos at the POS and tell the salesperson that
the number is invalid rather than waiting for a "DECLINE" from the bank.

This is mostly OK (actually the last digit is also summed up :-), but
both this descriptions and originally posted C code are somewhat too
complicated in their description of this simple task. Below is
attached re-implementation in Perl. The whole algorithm consists
really from "while(length) {...}" loop plus one folowing statement.
This program is happy with all credits cards which I have here handy

The lesson here is, of course, that one shouldn't be using this algorithm
to determine if a card number is _semantically_valid_, just
_syntactically_correct_. Just makin' sure the card-number data probably
got through correctly, etc. Unfortunately, we've got a lot of firms out
there that are using this as a "checker" of "goodness" of these cards. I
call that an invitation to fraud. Maybe this should go to comp.risks...

I've been trying to write a tablet driver for my old black NeXTstation. As
there's absolutely no documentation on what InstallTablet.app or the driver it
installs does, I've tried to use DPS stuff (sendevent, setmouse, ...) and
managed to get it to do nearly what it should - the only thing I couldn't get
to work is mouse-clicks!
So my Questions:
a) Has anybody some idea on how to simulate a mouse-click via DisplayPostScript
or Journaler, etc.?
b) Has anybody any documentation on how to build a tablet driver like the one
InstallTablet.app uses?
Thanx in advance

I received the first issue of NeXT's replacement to NXApp - OpenStep journal
on Friday, and I am most impressed by it's content. The articles are well
written, and in sufficient depth that they are self contained articles rather
than pointers to existing documentation.
Despite receiving the Spring issue in late July, the journal is timely since
it details those important differences between developing for NEXTSTEP 3 and
OpenStep which we will all face when NEXTSTEP 4.0 is released. It's good news
for those who, like myself, didn't realise the extent to which the interface
has been rationalised for OpenStep - truely NEXTSTEP is maturing into a very
elegant development environment.
If the editor Cynthia Closkey can maintain the range and depth of articles in
subsequent issues (and now it's Summer I hope to get my next issue shortly),
then the subscription will be money well spent!

Does anybody know how to get hold of a list of all application objects of

If you're using the new IB, just create a dynamic palette containing a
textField with the desired font and then use it to create new textFields.
Or you could do something similar with the old IB by creating a nib
containing a window with one of these textFields which you'll copy and
paste into your new window.
Of course, neither approach will help for setting the fonts on
existing textFields. If changing nibs will require a lot of work, I
either make the changes programmatically at run-time or write a simple
IBMole client that opens all nibs that need to be modified and do the
modifications programmatically within IB.

Hello,
I believe that the kernel would also have to support the alias
option as well. We moved our WWW server to a different platform
because of this. We also got pre-compiled binaries for the other
platforms. (Besides, I would rather be compiling on the next

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.

Forget anything you've ever heard about uniform operation within
GUI's! You are right, usually "command-3" and "command-4" can be
used for copying and pasting font settings. In IB you can't,
because those shortcuts are used elsewhere to bring up the inspector
panels for size- and help-inspection. Ok. Lets try the menu. Select
the button you'd like to copy the font settings from. Hmm, doesn't
work, the menu item is disabled. Try to edit the buttons title
double clicking it. Great, it works, the menu item becomes enabled,
and you can copy the font settings. Now lets select the button to
which you want to paste the font settings. Oops, forgotten to double
click, otherwise the "Paste Font" menu item keeps disabled too.
But now: Click "Paste Font", and ...
... PING, sorry, doesn't work.
You can not copy/paste fonts within IB. You can't. :-(
But don't worry, on other platforms you can't either ... :-)

In the first article, page 15, it mentions that under OpenStep,

This is a GOOD thing ... by using declarations of the form '(SomeClass *) var'
instead of 'id var', all you do is provide the compiler, at compile time, with
enough info to notice any bad parameters. It also is a little 'self
documenting', since it clearly indicates which class matches to which
parameter. Again, this improves the compiler's ability to figure out whats
wrong, it is simply policy & discipline, not a change to Objective-C.

This technique is known as "double-add-double-mod-10" and it is also used
to compute the check digit on CUSIP numbers (the standard number assigned
to almost all financial securities). This algorithm is superior to the
simpler mod-10 approach because it catches both "off by one" and digit
transposition errors.
As someone else pointed out, this algorithm only catches syntacial errors,
but as al of us programmers know, those are the most common kinds. 8^) I
know our credit card submission machine is programmed to reject such "bad"
numbers before it will call the bank to confirm that the account is in
good standing, which is a separate matter.

Thank you. This is part of what was worrying me We are not moving
to C++ style static-typing at all. It's just that the compiler is
(potentiallyntially) going to generate lots of warnings (especially on
ported code).
How extensive is this ? Is it just the OpenStep classes that have
statically typed methods ? Or all all classes required to be statically
typed ?

It's quite possible that I'm being muddle-headed. But suppose I write
an app that uses many threads. And it occasionally becomes necessary
for one of the threads to create an object and pass it to another
thread. For example, if one thread is a front-end and one thread is
an engine. We could encapsulate messages in subclasses of NXData.
Now, the front-end might actually care what the object is. But, to
the back-end, all that is important is that it respond to some
protocol.
The point of the question was this: Will I have to make a subclass of
NXData that responds to the protocol (and let the back-end know about
it) in order to avoid compiler warnings ?
Note that I'm not taking a position on whether this is good or bad.
I'm just wondering what is the case ?

Andy

I'm not sure you answered my question. The point of my
query is illustrated by the following example:
Classes C1, C2, ... C47 are subclasses of Class B14
Classes B1, B2, .... B106 are subclasses of class A2
Classes A1,A2,A3 are subclasses of some primordial class.
Now, all these are (to some extent) polymorphed. But the B and C classes
add in a few more protocols (which the calling code can check using
conformsTo if necessary).
If I have an id, and I have to declare it, I might, conceivably,
have to delare it as a pointer to class A2. Liek follows:
A2 * pointerToSomething;
Now what happens later on in the code, when I use methods from the subclass.
Do I actually get methods from the subclass (in which case, I could
conceivably just decare all my ids as NSObject * and be done with it).
Or else, at some level, I am using the wrong methods.
What happens when we message the object pointed to A2 and ask it
what it's class is ? Who answers the conformsTo questions ?
Etcetera.
Another issue is that my code might not know, in advance, what
the object is (just that it obeys some protocol). Do I actually
have to create a "virtual object" (e.g. one that reponds stupidly
to the protocol methods) to avoid compiler errors ?
And so on...I'm just not reassured by a blanket statementthat
"this is a GOOD thing."

This is Objective-C. You *always* get the method implementation
for the class itself. Type declaration has *nothing* to do with
what happens at run time. The reason to avoid declaring all objects
as id or (NSObject *) is so that the compiler can warn you when
you pass an object that really shouldn't be passed. You can still
do it, and at run time the message will still be sent, and if the
object doesn't respond to it your program will crash. But at
least if you statically typed the method you can have the warning.

I can't quite make sense of this question. It's fine for your
code not to know what class the object is, as long as the object
actually responds to the methods your code thinks it does. If
you type things as:
- (void)setDelegate:(id <SomeProtocol>)myObject;
and pass in an object *not* declared as conforming to SomeProtocol
or of a class conforming to it, the compiler will warn you. You
don't have to do anything "virtual" (whatever that means). It all
just works.
If you mean, "My code wants to use pointerToSomething as an
object conforming to a protocol rather than as an instance of
class A2"...well, then, your code should declare it as an
object conforming to the protocol instead of an instance of class
A2.

Hi -
Give this a try:

You can remove/add architectures as appropriate. Another idea is
to put a target in your Makefile.postamble that will do the build

fat ::
make $(MFLAGS) "TARGET_ARCHS = i386 m68k hppa sparc"

This is an API change, not a language change, so OpenStep classes
(and protocols) have statically typed methods, and you are free to
do whatever you want with yours. Since statically typing helps
catch bugs, though, I encourage its use. :-)

Well, you have to make a subclass of NSData to implement your
scenario at all.... However, since you define the front end,
the back end, and all of your API, no, you don't have to declare
the types in your methods. If you were to pass the object to
some (hypothetical) OpenStep method that required a protocol
declaration, then you either have to declare the variable you
pass as conforming to the protocol or do a type-cast to avoid
a compiler warning. I hope that clarifies things....

This is a GOOD thing ... by using declarations of the form '(SomeClass *) var'
instead of 'id var', all you do is provide the compiler, at compile time, with
enough info to notice any bad parameters. It also is a little 'self
documenting', since it clearly indicates which class matches to which
parameter. Again, this improves the compiler's ability to figure out whats
wrong, it is simply policy & discipline, not a change to Objective-C.
Will that be (SomeClass *) or id<SomeProtocol> ?

Subject: Resizing within SplitView
Date: 24 Jul 1995 15:48:19 GMT
Organization: Swiss Bank Corporation, Swiss Bank Center, Zurich Airport
Distribution: world
Message-ID: <3v0fc3$rks@op1d56cmp.il.us.swissbank.com>
Hi all,
I am developing an application using a SplitView for the first time, and I
am having problems with the resizing. I have no problems with the bottom
half of the split view, but the top half really screws up.
I the top half of have my SplitView, and in it are three main objects. At
the top there is a 1x5 text matrix at the top, which act as titles. Next,
below this, there is a ScrollView, into which I put a large matrix. At the
bottom, there is another 1x5 text matrix. Each object is the same width -
they are stacked on top of one another
No matter how I set the springs, I can never get the re-sizing to behave
properly. I want the title matrix to stick to the top of this half of the
view. Likewise, I want the text matrix at the bottom, to stick to the
bottom. I then want the ScrollView to stretch in between these.
I can get the two matrices to stay where I want them, but then the problem
comes with the ScrollView. It always seems to work properly with the
bottom matrix, but then it always moves over the top of the top matrix. If
I completely close up the SplitView, then the ScrollView sticks to the top
of the SplitView, and the top text matrix is never seen again!
I can get them to work together, but that means not having the ScrollView
vertically expandable, and that would not be very good. Does anybody have
any ideas what I am doing wrong (if anything). I have tried EVERYTHING
with the springs, and the scenario explained above is the BEST case I can
find. These re-sizing problems are really screwing up an otherwise good
application.
Cheers

Message-ID: <TIGGR.95Jul26154336@cobra.es.ele.tue.nl>
Available as ftp://ftp.es.ele.tue.nl/pub/tiggr/tl-0.09.tar.gz is a new test
version of libtl. For more information on libtl and other sw by me, see
http://www.es.ele.tue.nl/tiggr/sw/index.html#libtl. --Tiggr
STATUS
This is a test release of TL. It is by no means a complete library
(yet). Lost of things are still missing, see the file TODO (in the
TL distribution) for more information.
NEWS
Changes in version 0.09
Provide elapsed time constrained incremental garbage collection.
Allocate objects from chunks the size of the virtual memory page
size. Detect and re-use empty chunks.
New classes: TLSet, TLStack.
Documented, at least partially, garbage collection, its use and its
parameters.
Fixed numerous bugs and mis-features.
DESCRIPTION
TL is a basic Objective-C library, which happens to incorporate a
Lisp interpreter, which provides a seamless integration between
Objective-C and Lisp. (It is neither common lisp nor emacs lisp; it
is probably best described by the name tiggr's lisp.) TL provides
elapsed time constrained garbage collection to instances of TLObject
or a subclass thereof.
TL provides the following classes: The `root' object TLObject, a
patch for existing root objects (like TLPatchObject), TLString (and
TLMutableString), TLRange, TLDictionary plus enumerators
(TLDictionaryEnumerator, TLDictionaryDictEnumerator,
TLDictionaryKeyEnumerator, TLDictionaryValueEnumerator), basic
streams (TLFDStream, TLFILEStream), TLSocketStream
(TLInetSocketStream, TLUnixSocketStream) plus addresses
(TLInetAddress, TLUnixAddress), TLStringStream
(TLConstantStringStream, TLMutableStringStream), TLBase64Stream
(TLBase64InputStream, TLBase64OutputStream), various other streams
(TLBufferedStream, TLHTTPStream, TLSneakStream, TLStreamStream,
TLSyslogStream, TLTelnetStream, TLWrapStream), lisp specific classes
(TLCons, TLConsEnumerator, TLLDelegate, TLLInvocation, TLLLambda,
TLLLex, TLLSubroutine, TLLTag, TLNil, TLSymbol, TLSymbolValue) and
various others: TLDate, TLMimeItem, TLNumber, TLRunLoop, TLSet,
TLStack, TLURL, TLVector and TLVectorEnumerator. Furthermore, it
includes a host of Lisp invokable (but C written and thus also C
invokable) functions.
If reference counting is not provided by another library, TL
provides reference counting and an NSAutoreleasePool.
TL has been tested on HP9000/735 HP-UX 9.05 with the GNU 2.6.3 and
2.7.0 runtime, and on a NeXTstation Mono Turbo NS3.3 with the NeXT
runtime.
TL is distributed under the GNU General Public License. TL comes
WITHOUT ANY WARRANTY. See the file LICENSE in the TL distribution
for details.

make debug 'OTHER_CFLAGS=-arch i386 -arch m68k'
...seems to do the trick under NEXTSTEP 3.3. You might have to use
'ALL_CFLAGS', or possibly even just 'CFLAGS', depending on just how you

From the NS 3.3 Developer Release Notes:
Reference: 42975
Problem: Bitfields may not work properly with -O2 optimization.
Description: If you use -O2 optimization, the compiler may return a
wrong value in a bitfield.
Workaround: Don't use -O2 optimization.
Since NeXT still specifies -O optimization in their system Makefiles,
I think I won't risk stepping beyond to -O2 or -O4.

Excuse the previous partial post.
We are trying to port some software from SunOS4.1 to the NeXT. This software
uses a library, dlfcn, available on the Sun but which we cannot find on the
NeXT. This library has the following brief discriptions of its functions
dlopen( ) /* open and map a shared object */
dlsym( ) /* obtain address of symbol */
dlclose( ) /* remove a shared object */
dlerror( ) /* string representing last error */
Does anyone know
1. Where we could obtain this library for the NeXT?
2. How to accomplish equivalent operations with a NeXT library, for
example, rdl?
We also have some HPs running NEXTSTEP so a similar question would apply there.

I have a program that repeatedly reads part of a large file and then closes

I have noticed that the program loses HD space each time thru the loop and I
cannot regain the lost space untill I actually shut down the computer and
restart Because of this problem I can only run the loop about three times, at
which point I've eaten up the 64MB free on the HD before I start.
The program is really simple, using fgetc to read the file, fopen to open and
fclose to close the file.
Can any kind soul tell me if this is a known problem in either UNIX or
NeXTStep programming and if there is a simple cure. My local experts think
this is not a UNIX problem but I don't know myself.
I'm using Release 3.2 on a NeXTStation(Motorola).

The correct way to do this (for a ProjectBuilder Makefile) is:
make "TARGET_ARCHS=m68k i386 hppa sparc"
You can list any number of target architectures, you don't necessarily need
to list them all...

Eval.app is not an ObjC interpreter. It's more like an incremental compiler of sorts. That feature of it isn't particularly usefull thouygh.
I've heard that Richard Stallman and/or some GNU folks are working on a free C interpreter that will be extended to support Objective-C though.

Date: 27 Jul 1995 15:23:34 GMT
Organization: University of Cambridge, England
Message-ID: <3v8b1m$46n@lyra.csx.cam.ac.uk>
After some experimentation I have discovered how to find out which font applies
to an embedded cell in a Text object. This is useful if the purpose of the
embedded cell is to represent a variable (like a page number), and then in some
cases you need to render the actual page number in the correct font. My
earlier posting passed on a suggestion I got from somebody else, asking why it
doesn't seem to to work. I now know the suggestion turns out to be incorrect:
apparently, the cached curRun always refers to the LAST lay of the current line
by the time the cell is messaged.
Instead, a method that seems to work is to look at all the lays in the current
layarray, and then to find the lay that the embedded object is in. Embedded
cells seem to be put in their own lay. (Dangers: the Text documentation is
incorrect for getLocation, and the cell's x's and the lay's x's disagree by
around 2 pixels anyway). Fortunately, a safe comparison is by upper bounds.
Ignoring the last lay (which seems to be blank), scan back from the penultimate
lay, comparing its x with the location of the cell in the Text object. The
first lay encountered for which the cell's x >= the lay's x is the lay for the
embedded cell. Return its font. This is illustrated as follows, for a method
that is defined for the embedded cell class, and to be called by calcCellSize
and DrawSelf:inView:
- (Font *) getFont: (Text *) t
{
NXLayArray *la;
NXLay *lay;
NXPoint pt;
NXRect fr;
int k;
float x;
struct textDef { @defs(Text) } *td; /* standard trick to break protection */
td = (struct textDef *) t;
la = ((NXLayInfo *)(td->_info))->lays;
k = la->chunk.used / sizeof(NXLay);
if (k > 1) k -= 1; /* just in case only 1 lay (shouldn't happen) */
[t getLocation: &pt ofCell: self];
[t getBounds: &fr]; /* the Text docs imply this is
x = pt.x - fr.origin.x; /* not necessary, but it is. */
while (k--)
{
lay = &(la->lays[k]);
if (x >= lay->x) return lay->font;
}
return /* your default font here: this shouldn't happen */;
}
Can somebody say whether there is an easier way? I don't like having to do
this sort of thing with appkit objects (i.e. breaking their protection, not
believing the documentation, having to experiment with their internal
datastructures, etc). In particular, it would be good to have a comment from
somebody at NeXT.

libposix.a and libsys_s.a because of duplicate symbols. We are porting code
which requires the Posix libraries.

Help!!
I've stumbled across a very strange behavior on NS 3.3 Sparc. An app I'm
working on runs fine on a Sparc 5; when I run it on a Sparc 20 running the
same version of OS (with the same patches), it starts up but soon goes
berserk.
Essentially, the process loses connection with the message server for the
event queue. The weird part is that if I run the binary from a terminal
window (like " $ xxx.app/xxx ") instead of double-clicking the app icon
(or running " $ open xxx.app ") it works fine.
Can somebody enlighten me as to what might be going on within the app
wrapper that doesn't happen when running the program from the command
line?

Hi,
as far as I know this does not work at all. It's either POSIX or AppKit.
I found a hint in the release notes that you cannot use POSIX and the
AppKit at the same time and that is probably what you would need.
This is what the developer release notes for NS 3.2 say:
Building POSIX applications is now supported. To compile POSIX 1003.1 conforming
source, specify the -posix flag to cc. Note that POSIX kernel interfaces are not
supported for NEXTSTEP applications.
Hope that helps (although this is probably not what you wanted to hear :-)

We are running a program on a NeXTBox with NeXTStep 3.2. From time to

this is an interactive program, we can't really repeat the error since
we are not sure what sequence of events have to occurs to trigger the
error. We are now trying to find a memory watcher program that will
write to a log more information when a memory access violation occurs

unsafe usage of dynamic allocated memory in the program and where.
That Mallocate... program didn't help much. I read about some program

concern it might not work right on NeXTStep. Any suggestion ?

The correct way to do this (for a ProjectBuilder Makefile) is:
make "TARGET_ARCHS=m68k i386 hppa sparc"
You can list any number of target architectures, you don't necessarily need

Hi unix lovers,
I'm writing a non Appkit daemon and have the following problem:
There is a function void foo(){..} and I want to call this function say every 5
seconds. I know how to do it using DPS, but have trouble to implement it for
plane unix.
I tried the following ...
main () {
signal(SIGALRM,foocaller);
alarm(5);
pause();
}
void foocaller (int data) {
foo(the right arguments for foo);
signal(SIGALRM,foocaller);
alarm(5);
}
.. but foocaller gets executed only once and then the process stops?!?!
Is it something wrong with signal() and/or alarm() implementation or I'm
missing something important here?
Thanks

I read in the PPP documentation a comment saying some of the POSIX is
broken in NS 3.2. To be more specific, the new chat program can only be
compiled properly using NS 3.3 which has fixed the POSIX problems that chat
notices during compiling.

Simple? - NO!
The RenderMan interface provides no functions to insert text into graphics.
That's why all programms doing so have to implement a conversion between
some font format (e.g. PostScript) to RenderMan commands.
For this use I've converted 2 fonts (Helvetica and Times) from PostScript to
RenderMan format. What you get by this is a RenderMan definition of the
extruded characters as CSGs consisting of bilinear patch-meshes with
polygons in the front and back embedded in two subclasses of N3DShape -
CharacterShape and TextShape.
If you're interested - mail me.

William,
We have invested considerable effort into understanding the Text's inner
workings in order to use the Text object to display fully justified text,
kerning, right, centre and decimal tabs, etc.
Hence, I can reveal that the point that your code is missing is that the
NXLayArray contains the id of the embedded cell. This saves messing around
with cell locations.
I have included an alternative to your solution, but bear in mind that this
simple approach only works in the same case as your solution; when the
current LayInfo represents the line containing the embedded cell.
@interface Text(CedarSystemsCellFont)
- (Font *)fontForEmbeddedCellInCurrentLayArray:eCell;
@end
@implementation Text(CedarSystemsCellFont)
- (Font *)fontForEmbeddedCellInCurrentLayArray:eCell
{
NXLayArray *la;
NXLay *currLay, *lastLay;
la = ((NXLayInfo *)_info)->lays;
lastLay = la->lays + ((la->chunk.used / sizeof(NXLay)) - 1);
for (currLay = la->lays; currLay <= lastLay; currLay++)
if (currLay->run->info == eCell)
return currLay->font;
return nil;
}
@end
Personally, I prefer to add a category like the above to the Text object
rather than use @defs in other object's code.
Good luck,
Paul Heffernan, Product Development Manager.

The typing has no effect on the compiled code. It's just to get clearer
source codes both for the compiler and the programmers. The old untyped
declarations works just as before if you prefer that.

Hi,
I have the following problem:
I use the POSIX sigsetjmp function.
When I try to compile I get the error:
cc -g -pipe -O -DDEBUG -DNEXT -I/home/Dominik/Unix/include -I. -I../modules -c tester.c -o tester.o
tester.c: In function `main':
tester.c:215: too many arguments to function `setjmp'
This is sigsetjmp is obviously just a wrapper for setjmp, but it does not discard the 2nd argument.
Ok, it's posix, therefore I tried:
cc -g -pipe -O -posix -DDEBUG -DNEXT -I/home/Dominik/Unix/include -I. -I../modules -c tester.c -o tester.o
tester.c: In function `main':
tester.c:215: too many arguments to function `setjmp'
Is this due to NeXT's incomplete POSIX Implementation or am I just too stupid to solve this ????
(No answers needed for the second case :-)
Any help is welcome.
thanks
Dominik

A couple of days ago I asked for any experienced advantages using IB+ObjC
vs. any more traditional GUIbuilders+C/C++. While the tenor was clearly biased
towards IB+ObjC with its dynamic features there was also a strong emphasis
on the non-usability of IB for any 'real-world' large application development.
The mentioned reason is IB's inability to cope with existing classes .[hm]
files and correctly patch such files when it comes to a later 'Unparse'.
Instead people may use IB for a first approach but later switch to their
editor to alter outlets and action methods, which they succesfully 'Parse'
in IB. Hey, this is stone age technology.
Again and again NeXTstep is quoted to have a -if not the - sophisticated
development environment. But it seems in reality it is merely useless! Ib does
have the outlet/action manipulation facilities. It just screws existing source
files.
I cannot truly believe this yet - and surely I do not want to. So, has not
someone come up with some diff/patch combination to circumvent this hassle? Or
do you professional users really forsake IB when it comes to true work?
If I remember correcly I saw Delphi handle this very well during a demo at
Cebit.
Is NeXTstep loosing another race?

OTHER_CFLAGS seems to work on the command line since at least NEXTSTEP 3.0.
At least I've been using it to control the build environment from automated
scripts to do several builds (with different flags during each build) for
the products I work on. But YMMV.
> What about OTHER_LDFLAGS?
No good. It wouldn't build the .o files FAT.
It's good that NeXT makes the "OTHER_XXX" Makefile flag hooks available for
developer use. It's too bad that they didn't use CFLAGS and LDFLAGS
instead of the OTHER_XXX versions, though. No one except PB-based projects
knows what that is, or knows what TARGET_ARCHES is either, for that matter.
If one builds projects which use source off the net, being able to simply
specify CFLAGS on the command line and control all compiler flags for all
of the source would be easier to deal with.
---------------------
Opinion: NeXT should've read the FSF programming standards document and the
Makefile info pages more carefully; these give good advice on how and why
to set up different levels of command-line flag specifications for
Makefiles. NeXT should've also started with GNU make, rather than using
their own incompatible version.

Tell me about it! :-(
I've had to modify Makefiles and use the unsupported library.make and a
modified ProjectBuilder.app which understands library projects under
pre-3.3 NEXTSTEP releases. I suppose this means that I can't be considered
to have a stock configuration.
I'd encourage the curious to experiment with "make -n" (which does not
execute the commands, it just shows you what would happen) and see for
yourself what happens when you specify various flags on the command line.
If you understand Makefiles well, then you can make your world happier by
doing such things as adding "-pipe" or "-Wno-precomp" (essential for doing
a -posix build!) to /NextDeveloper/Makefiles/app/common.make. Changing the
optimize flags to "-O3 -fno-omit-frame-pointer -ffast-math" may be
appropriate for many purposes. Switch to "-fomit-frame-pointer" for
non-debuggable but better performing production release builds.

Hello:
I am trying to install the OmniImage graphics filter as a
service so that my internet browser (Omniweb, I think) can
properly display graphics. I am running NeXTSTEP v3.3 on a
Pentium system. Documentation from OmniImage refers to the
NeXTSTEP Developer Library for the procedure for installing
the graphics filter as a service, but this approach looks too
daunting for a non-NeXTSTEP programmer like me. Isn't there an
easier way to add services?
Even if I use the method described in the Developer Library, don't
I need to know alot of technical details about the filter before I
can install it as a service? Where can I get all the required
information? Do I have to go back to the publisher for this data?
Any help is greatly appreciated.
Thanks in advance,
John

My specific question is: the Text object's method "defaultParaStyle"
returns a pointer to a NXTextStyle structure. I'm guessing that that
structure is being dynamically allocated. If it is, am I responsible
for freeing it when I'm done with the structure?
The more general question is: when the appkit returns a pointer to
some structure, is that structure dynamically allocated and if so,
who's responsible for freeing it.

Since you have to switch to your stone-age editor to make your new
actions actually do anything, why bother using unparse even if it didn't
overwrite what is already there? How do you propose unparse should work?
I want to place my outlets and actions in certain places in my source
files, so I don't want some GUI app placing them in some arbitrary
location. Unparse is just a cute demo feature. Real [wo]men don't use
unparse :-)
You're mired in the code-generator paradigm so common with UI
builders. IB isn't a code generator; it's an object editor and archiver.
This is a much more powerful than the code-generator paradigm. If you'd
quit trying to mold IB into a code generator and use it as an object
editor and archiver, you'd get a lot of useful work done.
> Again and again NeXTstep is quoted to have a -if not the - sophisticated

Well, it's certainly useless for those who merely whine about it. For
the rest of us, it's been an incredible development tool. Our domain
experts used to have to write UI specs for programmers to implement.
After several cycles of implementation, review, reimplementation, etc.,
the UI was done.
With IB, these non-programmer domain experts now write the UI
specification using IB and then programmers add their nibs to the project.
Not only does this save a tremendous amount of time, but it results in a
much nicer UI because the domain experts are very close to the end-users
and know what they need and like in a UI.
Our programmers have created custom palettes that allow our
non-programmer domain experts to "graphically program" by making
connections in IB to and from our custom palette objects, so their nibs
"just work" once done. They're not merely screen paintings, but they
unarchive fully functional windows at run-time.
If you consider this to be "stone-age", then I'm a happy caveman, I
guess :-)

I haven't used UnParse on any of my projects (except for, of course,
the initial .hm creation) since I first wiped out some work in the
2.0 days :( But, I think, if my memory isn't playing trix on me,
that in 3.3, after you have started work and after the initial
unparse, unparse becomes disabled in IB, so you have no choice but
to say no :)
They should probably rename the unparse function to something like,
initial .hm files creation. The [un]parse paradigm implies that
unparse should be used frequently (when it really makes no sense
to do so). DragnDrop of the .hm files over the IB .nib windows is
what you really want...actually you want PB to do that update for
you automatically...maybe in 4.0?
Gosh, I feel so un-lucid after way too much programming and tea
%-)

Hi all of you,
I use heavily the FK with the autorelease mechanism. As I don't use
EOF, I use the PoolApplication application class (from some
NextAnswer, I cannot just now remember the number), which releases
the autorelease pool in the sendEvent: method.
The problem is here: when the application runs on background,
driven either by DO or 'internally' using the
perform:with:afterDelay:cancelPrevious:, the sendEvent: method is
not used, thus all autoreleased objects are kept in memory.
I can imagine some solutions, but all of them are dirty. I'd like
to change the PoolApplication class such way that the _releasePool
method gets called not only in the sendEvent: method, but after any
DO event and perform:with:afterDelay:... event as well. Is it
possible? How? (Or would it be a bad solution? Why?)
Thanx,

This is the free TabMatrixPalette that should be at ftp.cs.orst.edu.
It's modeled after the control NeXT uses in the new IB, but doesn't
include a swappable view. There are several of these available including
UHSelectView. It would be nice if a swappable view were integrated into
the TabMatrixPalette, and the source for all of these is available, so
wouldn't this make a nice little programming project for someone ?-)

This sounds like the {DB,NX}TableView that NeXT includes in the DBKit
and EOF palettes. These can be used without a database.

newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>

Check out the source code for the MiscKit MiscSavePanel class... it demonstrates
how to overide the hidden _validateNames:checkBrowser: method of the save panel
class. This may not be very clean or legal but it should allow you to obtain

Are you building a version of pgplot for NeXTSTEP DPS window (not X)? If
so, I am quite interested in seeing the results.
I use pgplot (not on NeXT) to produce a PS file, but it produces
upside-down images if viewed with Preview.app on the screen. (It's of
course not a problem if printed on paper) It would be nice if you add
NeXTSTEP driver for that.

"conio" is a library used on MS-DOS computers to do "console input /
output" on a PC's text screen. UNIX computers are terminal-oriented and
have no text screen in that sense. You can look for the UNIX library
"curses" which has some of the functionality of "conio" but you have to
rewrite your program to use it. Search for "curses" in the man pages to get
more information.

I'm a bit confused by the listener class. Tried reading the ducumentation
but I'm not much better off. I want to access ALL the methods in an
application via command-line calls, so decided that a speaker/listener
combination would work well. I'm trying to get the system working first on
the demo app "Lines". A simple task should be to toggle the on/off state
of the display with the toggleRun method.
I have created the appDidInit:sender method in MyApp.m, and entered the
following code (pretty much as in the documentation):
=====================start code=================================
- appWillInit:sender
{
myListener = [[Listener alloc] init];
[myListener setDelegate:self]; //send incoming messages to self
[myListener checkInAs:"myPort"]; //name the new port
[myListener addPort]; //register it
[NXApp setAppListener: myListener]; //set it as the default port
// for application?
return self;
}
- toggleMe:sender
{
NXRunAlertPanel (NULL, "This will toggle me!", "goodbye", NULL,
NULL);
return self;
}
=======================end code===============================
I access this through a wee spot of code in Eval3.3 (gleaned from
Message.app), with which I send a "toggleMe" message to "myPort". Nothing
happens. If I send a "unhide" message this makes it through. How do I go
about making it respond to other messages? How does this all relate to
msgwrap which I don't understand at all?
At a guess, do I have to subclass Listener using code produced by msgwrap
(how do I do this?) then use this as my listener?
TIA (this is probably very simple but I've wasted too much time on it
already)

I got several email answers on my post and they said (as I already found

suited for business graphics.
The NX3dPlot app (on the archives) does a pretty good job at it though
using some neet tricks and I recommend having a look at it.

1. Be sure to have the complete sources of gcc 2.6.3 and gpc 1.1 and the
two gpc 1.1 patches available so far.
2. Compile gcc. Use something like
./configure --build=next --prefix=/foo
(/foo is an example for the installation directory in which gcc and gpc
will be placed.)
WARNING: You cannot move the compilers to another directory later.
3. Make stages 1 and 2 and install the C compiler as described in the
install documentation. Leave all the .o-files in place!
4. Mske a backup copy of the configure shell script of gcc.
5. Now copy the gpc files JUST OVER the files of gcc in the gcc source
directory. This seems to be the easiest way to avoid some of the problems
one might have when compiling gpc. (If you want to keep an "untainted"
version of the gcc sources, you should make a backup copy of the whole
source directory).
6. There seems to be an error in the gpc makefile. Edit "Makefile.in" and
change the line
RTS_GCC=../$(gccdir)/xgcc -B../$(gccdir)/ $(RTS_WARN)
to
RTS_GCC=$(gccdir)/xgcc -B$(gccdir)/ $(RTS_WARN)
7. Make a subdirectory gpcbin in the gcc source directory.
8. cd to this directory and configure gpc as described in the gpc install
documentation. As arguments for "gccsrc" AND "gccdir" specify the gcc
source directory.
9. VERY IMPORTANT: erase the files
dbxout.o
expr.o and
function.o
in the gcc source directory.
10. Set a search path to your newly created gcc compiler. In my example
this would be
setenv PATH $PATH\:/foo/bin
11. Now compile and install gpc as described in the documentation.
Well, this worked in my case, I hope it'll do in your case, too.
Good luck!

I now moseDown on my subview I get a memory exception. Further
inspection in gdb reveals that the contents of the C++ instance used
in the first mouseDown have changed to meaningless values, hence the
memory exception as these values are pointers. Why should clicking
out and back into my App do this? What have I done wrong?

Typically, what you need to do is run fsck (first without making changes,
so to see that how much it can recover). Because the master block of the
file system has with 99.9% probablility been overwritten, you would have
to specify the -b option to specify an alternate master block (you were
given a list of alternate master blocks when you first newfs'd the disk,
you of course printed those out, didn't you?). On NeXTstep, block 16 is
always an alternate master block, but I'd think it highly likely it was
also overwritten (one way to find out the alternate master blocks would
be to take an identical hard disk and partition/newfs it identically).
Refer to "man fsck" for further details.
If all else fails and the disk is really of great value, local hard disk
dealers can probably direct you to data recovery companies who deal with
this kind of stuff almost daily.
PS. Which installer package was this, so I can avoid it?

Try: "nidump hosts / | grep hostname"

198.4.126.11 hypnos

Using execve(), you can run nidump from your program and
read its output by creating a pipe() and reading it.

I am involved with a software project that needs to act on exception codes
(relating to debugging and breakpoints) returned by Mach.
The problem is these codes are available for all architectures except for
Motorola ('m68k).
More specifically the codes are available in:
'NextDeveloper/Headers/mach/'aaaa'/exception.h
where 'aaaa' is one of 'i386', 'hppa', 'sparc' or 'm68k' for the
various architectures supported by Next.
The problem is the 'exception.h' file for the 'm68k' architecture contains
the simple comment '/* fixme */' while the others contain a complete list of
codes.
A call to NEXT technical support confirmed that this is a problem, yet at
this point, I do not want to pay $150 US (cost per support hour) or more
they want to charge for this.
Does anyone have any suggestions as to how to find these 'm68k' (a
reference, etc.) mach exception codes?
If so, please email me at 'rsmallwo@islandnet.com'

Hello,
This spring I installed the 2.6.3 version of gcc on my Station
(NS3.2), since the original one produced some coredumps on a file
generated by NAG's F90 compiler.
NAG F90 and gcc are cooperating well now, but:
the new compiler is unable to compile Objective-C programs. I get a
long listing of compiler errors (Parse error before ... ).
All these errors occur in the new appkit- (and objc, dpsclient, ...)
header files.
Does anyone know how to cure the problems (I guess it should be quite
simple, just maybe some wrong entry in some header).
I can manage to compile the NextStep-related programs with the old
version, but it's nasty; and I need the new version to compile my
Fortran programs.
Thanks for any inputs.
Alois

I believe "conio.h" is a MsDOS file. There's no exact equivalent in Unix.

This is all that I can tell you from the information you've provided:
sh (the bourne shell) or a subprogram invoked by sh has run into a
problem, and the PID (process id) for the program that died was 2819.
That's why the number changes every time: it's a new process every time.
You need to narrow down on where in your build your problem is occurring.
Project Builder will invoke make many times; and each time, make will
invoke cc and other programs many times; and each time, cc will invoke
sh many times, and... you get the picture.
I believe that both make and cc have command-line options that will
cause them to emit verbose logs of what they are doing. I don't know
what they are, but you can look them up. Capture that log info into a
file. Then, after the crash, you can tell exactly (or approximately,
at least) what file was being compiled (or linked, or whatever) when
the problem occurred. Then you can try compiling that by hand, or in
other ways try and further narrow down on the problem.

Distribution: world
Message-ID: <3vj63c$j1a@stc06.ctd.ornl.gov>
For some time I've been messing with adding a zoom ability to Draw. I
have gotten the ScrollViewDeluxe object from the archives and found it
does just about everything I needed by setting up a very simple app
based on the Demo "little.m" and extending it a bit so I could be sure
I understood the ScrollViewDeluxe class before I tried it in the Draw
app. I can get my simple app to zoom in and out fine, but when I try
the same thing in the Draw app, it either doesn't do anything OR it
gives a "broken up" image when scrolling.
I have found that part of the problem is related to the caching of
images and off-screen drawing done in the Draw app.
1) Is there a way to use ScrollViewDeluxe with the Draw app and retain
the caching?
2) How do I scale a TIFF image?
Suggestions and/or examples of ways to zoom in the Draw app would be
appreciated.
Thanks,

Hello,
I'm now writing a driver for a fast communication board we are currently developping at our
school.
It's the first time I write a driver for NEXTSTEP (and that I have to programm something for
NEXTSTEP), and I have some problems getting used with the driver kit. My problem is now the
following:
I would like to frok a new thread (not an I/O thread) and I used the c-treads functions
declared in the file <mach/cthreads.h> (cthread_fork, cthread_fork, ...). Then I tried to
compile the whole thing and I got the following messages:
Making TNIDriver_reloc.tproj

....
and a lot of more!!!
In my file, I included the following files:
#import <sys/time.h>
#import <driverkit/return.h>
#import <driverkit/interruptMsg.h>
#import <driverkit/generalFuncs.h>
#import <mach/cthreads.h>
#import <mach/mach.h>
#import <kernserv/prototypes.h>
I tried not to include the files <mach/cthreads.h> and <mach/mach.h> and then these errors
didn't appear any more, but the types any_t and cthread_t are not known.
In NEXT's documentation, I found nothing about this problem, and I don't what I should do. Do
I have to use the driverKit function IOForkThread, but as I understood, this function is
intended to be used to fork a new I/O thread and not something else.
Does anybody already had such problems or does anybody know a solution ?
Thank you in advance.

Well, I personally would prefer slightly another paradigm:
The IB would be project master (instead of the PB). It will store
all the @interfaces in its own, encoded form (of course including
the documentation :))), and it will open the editor windows to enter
only method implementation for objects, prepared in the IB.
Then it would be possible to do many cool tricks - eg. click to
object might enter to source the name of the outlet assigned to it
and so on.
Moreover, multi language programming will be much easier: there
should be only templates which tell IB how to export '@interfaces'
for diverse languages; then you might _easily_ write each method
using another language (should you really want to do such a
perversion). Integrating smart make feature we will got _really_
incremental compiler. The IB's 'test' feature starts to be _really_
usable not only to test a UI, but to test whole thing...
Surely there _are_ drawbacks; but, I would bet with a proper design
this paradigm might be as a great step as is today's IB+ObjC
compared with traditional environments.

Correct, but the answer is to run "/usr/etc/arp -a" and it will show you

I never said IB was useless in general.

IB has the add outlet/ add action functionality.
Now I do not want to refrain from using it on second and later code iterations.
Is this unjustified cause?
It is somewhat inconsistent to use IB to create classes and their .[hm]

I can see you have adapted to the state as it is.
Using strong words does not better IB's functionality.
I as a user want more functionality and rightly so.
You at least have solely given me a mere 'real {wo}women don't do it'.
If you are glad the way IB works now, I say lucky you.
Your example of IB usage is not a counter example to what I proposed.
Therfore it does not make my proposal invalid or leave it irrational.
It might be you found my words too harsh. They were meant that way.
Criticizing does not mean to condemn. I am far from that. But NeXtstep as well
as any other development environment I know does lack some functionality for
my taste.

You need to zoom the cache as well. When you get a zoom message, you
need to adjust the size of the cache for the stated zoom factor,
and scale the cache. When you composite either from the cache or an image,
you also need to temporarily do a PSscale by the zoom factor, since
compositing doesn't take view transforms into account. So, to sum up:
o resize the cache window
o scale the cache window
o scale when compositing

You're picking and choosing the articles you wish to consider in your
decision. I've followed the thread, and have seen no real bias for or
against IB in terms of large projects. Personally, I've used IB for a
number of large projects, and had no particular problems with it. The
Parse/Unparse "problem" is quite simply a straw-man, and is trivially
easy to work around. It's pointless to condemn IB for costing you ten
minutes on a four month project due to the Parse/Unparse "problem",
especially when it probably saved you another four months in the
bargain.
This is not to say that I don't think this minor annoyance shouldn't
be fixed. It should. I'm just annoyed by the extreme you're taking
it to (note the subject line).

Try adding -lMiscKit and possibly -all_load to the linker flags (either LDFLAGS or

I have an NXTableView where I want to be able to toggle the column header

table view is scrolled to the far right and the column header is toggled
on, it is drawn as if the table view is scrolled to the far left. As soon
as the horiz. scroller is moved, the column header is drawn correctly.
Anyone that knows how to do programmatically? I have tried with
setFloatValue to the horiz. scroller object, but it does not work.

This is almost certainly more easily done using Distrubuted Objects; it's
awhile since I did this, but...
Set up an NXConnection for the app in the NXApp's delegate when it starts
up:
---
- appDidInit:sender
{
[super appDidInit:self];
if (!(ourServer = [NXConnection registerRoot: self
withName:REGISTERED_NAME])) {
NXRunAlertPanel("Error in startup; could not register root",
REGISTERED_NAME,
"OK",
NULL,
NULL);
return nil;
}
[ourServer registerForInvalidationNotification:self];
[ourServer runFromAppKit];
return self;
}
---
then in the commandline programme you can make a connection to the app in
the following way:
---
if (![[Application workspace] launchApplication:APP_NAME]) {
fprintf(stderr, "Could not find or launch %s\n", APP_NAME);
fprintf(stderr, "Sorry, exiting\n");
exit(1);
}
/* Get the connection for the app on host machine */
n = 0;
while (!(rApp = [NXConnection connectToName:REGISTERED_NAME])) {
if (n > 5) {
fprintf(stderr, "no response after %d seconds - exiting\n", n);
exit(1);
}
sleep(1);
n++;
}
if (!(ourServer = [rApp connectionForProxy])) {
fprintf(stderr, "no connectionForProxy\n");
exit(1);
}
/* not strictly necessary */
[rApp setProtocolForProxy:@protocol(NeXTSpectMethods)];
[ourServer runFromAppKit];
/* now you can send commands to the app like this: */
[rApp newFromData:theNXData withTitle:windowTitle];
---
There may well be more elegant ways of doing this, however, in which case
I'd be pleased to hear of them!

- run the Configure program. At the question for cc flags, use "-O -DSHOW_UTT"
- run "make"
- and to install, run "make install" as root. To allow any user to run top
without being root, use setuid. "chmod u+s /usr/local/bin/top"

Hello, all.
I'm trying to ferret my way through the world of Distributed Objects. I
thought to build myself a nifty little CHAT facility, consisting of a client
app which would (a) show a list of currently logged individuals, (b) display
the conversational thread so far, and (c) take input to be posted; and a
server app which would (a) track login/logout events and (b) broadcast text
received from any one client to all clients on its list (including the
sender).
It seemed straightforward to me that, when a client sends the server a new
message to post, the server walks a list of known clients and hands the
message back to them. However, in browsing through the release notes (I'm
using 3.2 on Intel), I hit this statement:
After the client call completes, the server may wish to call
the client back (send a message to an object on the client).
In general, this won't work, unless the client is in the
middle of sending another message to the server. This is
because there has to be a thread of execution waiting to
serve incoming requests.
As I read this, by default there is no way for a server to arouse
the interest of a dormant client.
My first and most important troll for information is, what's the workaround?
If I grab the NXConnection and do a runFromAppKit on BOTH the server and
client sides, does that allow the server to tap sleepyhead clients on the
shoulder?
I guess my second question is more one of strategy (by now, you've no-doubt
figured out that I'm just past beginner stage with this stuff). When it comes
time for a client to send the contents of a scrollable textview to the server
for broadcast, it seems necessary to prep for the transfer by writing the view
contents onto an instance of NXStream. Should the stream be passed to the
server by a standard NXProxy arrangement, or is it somehow better to convince
the stream to pass itself over the wire?
Finally (assuming the problem of getting server messages to dormant clients is
solvable), I'm not sure how to completely close the window of vulnerability
for a client death in the middle of a server broadcast. Whether the server
sends its client list an iterator or does the
ct = [ clientList count ];
for ( i = 0; i < ct; i++ )
[[ clientList objectAt: i ]
postMessageFromStream: aStream ];
bit, what happens if a client dies in mid-loop right before its turn comes up?
I don't see how the invalidation mechanism can help in such a worst-possible-
case scenario, and I don't know how to code for that tiny little bit of
potential bad luck.
Any comments on any or all of these questions would be greatly appreciated.
Pls. note I'm posting from my home (non-NEXT) account...if you choose to
reply by NEXTmail, it should be sent to:
tappd@copernicus.sccsi.com
Otherwise, I'll check for comments here.
Thanks!

When I set the desired "autosizing" behavior of a TextField in Interface
Builder (with the "Size" inspector), the text in the TextField is
re-wrapped correctly when I resize the window.
Perhaps you did a "setWrap:NO" or so ?
You also have to be careful with setting alignment. If I recall
correctly, some combinations of *right* alignment and
setEditable:/setSelectable: cause the text not to rewrap.

Thanks for telling me how you took my post.
I thought I had made clear what I was criticizing but the responses seem to correct me.
As stated in the subject line I have found that particular misfunction of IB an annoyance.
I truly wanted to know how others live with that, how you work around or if you have found ways to fix this youself,
unbeknownst to me.
I consider this particular misfunction not neccessary to exist as it could be fixed. I am quite sure as I did just that
for a code generating button pusher.
But I still feel it is a small but inconvenient inconsistency in the object world of development tools.
In no way have I ever intended to say for IB to be useless in general. I do not think so, having used IB+ObjC to some
extent myself. But we can certainly do without another praise of NeXTstep here.
Sorry, if you feel I was not precise enough. I thought I was but I will keep this in mind.

I am new to NS programming. I want to write a program to keep some
records. Since it is for personal use, I guess I don't need the expensive
DB server (I found that its impossible to learn DBKit programming without
those server(s)). So I tried the IX Kit. But I found that the supplied
documentation from NeXT assume an expert knowing details of DataBase
concept and the philosophy behind the IX Kit. I read though the
/NextDeveloper/Examples/IndexingKit/Ledger and found it hard to learn
for a novice.
Learning NS programming with the documentation from NeXT, is something
like try to learn digital computer hardware by reading through a TTL
data book + some sample circuits (the Ledger).
I had nearly finished reading the 2 NS books from Garf + Maho & Alex.
The books have never touched any about IX (or other Kits).
Is there any better tutorial on the net ?
Further, is there free/shareware that can be used to browse through
IX objects; because there is no way to verify whether the structure of an
created XXX.store is what I intended to or not. Better yet, since I am
new, I need to keep on modify the structure, everytime I changed the
structure, I must either purge the already input data or write another
program to port the old data to new format; is there tools that can help
to move (merge) old IX.store to new one.
Thank you in advance.

NCSA Mosaic Common Client Interface (CCI)
version 1.1
March 31, 1995
NOTE: The Common Client Interface is a new, experimental feature. The CCI
specification and Application Programmer's Interface (API) will very
likely change in the near future.
The Common Client Interface (CCI) allows external applications to
communicate with running sessions of NCSA Mosaic via TCP/IP. The CCI
Application Programmer's Interface (API) supplies programmers with a
library of routines to communicate with Mosaic. Applications can use
Mosaic to fetch URLs or ask Mosaic to report the URLs selected by the
user. Applications can also pull in data from the web to the local program
space, essentially turning the client program into a potential browser
itself.
Currently, only NCSA Mosaic for X supports the CCI. With version 2.5, use
the CCI option under the File menu to instruct Mosaic to listen for CCI
communication on a specified port number. A port number may be any number
1024 through 65535. All client programs that communicate with Mosaic via
the CCI should have their own mechanism for specifying a communication
port number.

----------------------------
I have had exactly the same experience as this!
I was building a DOS partition on my boot drive about one month ago. I created
the DOS partition and then rebooted the computer with the DOS floppy disk.
The setup program started and offered to format my disk and install dos.
MS-DOS 6.22 formatted my 100 meg dos partition, and then begain immediately
formatting my 1 gig NEXTSTEP partition. I saw this and stopped it after
about 2-3%. I was livid, and made some phone calls to Microsoft demanding that
they pay to recover my lost data.
I finally got connected to someone at tech support at Microsoft who made the
brilliant suggestion "can't you just run unformat on the partition?". I had
to pay $25.00 to hear this and other similar calibre suggestions.
It turns out that Microsoft says that my dos 6.22 disks were an OEM product
with the company that I bought my computer from (Packard Bell), and
Microsoft said that Packard Bell had modified the boot floppy for dos. They
also said that THEIR dos disk would not automatically format a second hard
drive. I didn't believe it, and when I talked to Packard Bell, their tech
support said that they really don't make any big changes to dos setup - just
change some parameters. They said it must be a problem with Microsoft. At
that point, their only suggestion was to write a letter to Packard Bell
explaining what happened. Packard Bell said that for most people, this would
not be a problem since they only have one drive, and they use the entire drive
for DOS.
I tried many things to recover my data. I tried building another disk with
NEXTSTEP, and then manually mounting my damaged disk. It could not mount the
disk. I then deleted the DOS partition and remade the NEXTSTEP partition using
fdisk. I still could not mount the disk. I tried running the "disk" utility
with the raw SCSI device and searching for backup boot blocks and running fsck
with the alternate boot blocks. Nothing worked, and eventually I had to
reformat the disk.
I did lose some important data from the drive, and I'm being much more careful
since then with my data. I now have my main NEXTSTEP files on a disk with
1024 byte sectors, so it isn't even recognised by DOS! The setup program is a
very poorly handled install program by Microsoft, with total ignorance of any
other operating system. It's disgraceful that a company with such an inferior
product has become such a dominating position in the computer world.

I moved earlier this month, and found out at least one good reason
to get rid of back-issues of magazines (they are _heavy_). But,
before throwing everything out, or at least going through them with
a razorblade to save the good articles, I decided to look into the
CD-ROM archives that Miller Freeman offers. I'm interested in the
Dr. Dobb's, Computer Language/Software Development, and BYTE CD-ROMS.
Question #1: Anyone have feedback on the CD-ROMS? Good, bad,
neutral.
Question #2: Are these things usable on anything other than a
Windows system? Obviously I'd rather run this from NeXTSTEP, but
so far as I can tell from talking to the vendor's phone reps, "You
have to have Windows". Of course, I don't expect phone reps to
have a holistic knowledge of the field, either, which is why I ask
here.

There is a trully efficient:
#define ID id
@interface MyObject:Object
{ TextField * textField;
ID anIdNotForIB;
#if 0 /* I HATE IB PARSER */
id textField;
#endif
}
@end
Note that the comment is not neccessary :-)
Anyway, I now found useful to separate the IB defintion from the normal
definition by adding a
project-ib.h
in projects
This is mainly because if you have a hierarchy of classes to parse, you
have to parse each of the headers in the good order (Dragging multiple
files from the workspace give a random order)
In this file I give the IB vision of the classes, in the good order.

Archived objects - wether they are read from a nib file or another

I'd prefer a collection of true Objective C objects for building new,
customized WorldWideWeb apps from scratch. With an inter-application API,
you can only control an existing app, with all of the limitations.
I recall ZippyTech (?) had (has?) Telnet and Ftp objects, I'd like to see
something along those lines... And perhaps a HyperText view ?
(I wonder why all browsers seem to implement their HyperText view as a
subclass of Text. I think this will not make it any easier to implement
features such as tables etc.)

I need some help with "archiving". My objects already use the typed stream archive
mechanism to save to the disk the necessary data so as to read it in with a subsequent
execution of the app. This includes the NXWriteObject, write method, NXReadObject,
read method. It works great!!
Now I need to create a time-tagged archive of changing objects for replay at a later
time. I found that only on the first NXWriteObject for any object did a write method call is
generated. But on replay, for every NXWriteObject, there was a corresponding
time-tagged object that could be read by a NXReadObject except the data did not change;
it was the same as the one write method data.
Can I save the same object with different data over time with typed stream data or do I
have to setup my own data cruncher method using a stream? Tell me NeXT is not that
way!

First, the alarm() and pause() combination is doing what you told
it to do. pause() blocks until the *first* signal is received.
After the signal handler has been called, pause returns. So you
would need a loop around what you have now in order to get it to
work but your timing will be more accurate since the time it takes
to doo actual work will not perturb the 5 second frequency of signal
delivery.
A better approach is to use setitimer(). This causes a SIGALRM
signal to be delivered periodically (e.g. every 5 seconds). You
still need some sort of event loop around a pause or other
{
signal ();
setitimer();
while(1) {
do stuff;
if (need_to_quit_now)
break, return, or exit;
pause(), select() or something that will block periodically;
}
}

Archived objects also receive awakeFromNib messages, which are useful for

I figured it out; actually there is a minor problem with the configure
program. It correctly determines that I have an i386-next-nextstep3, but
it does not place this correctly in one portion of the Makefile,
specifically there is a line:
target= ... `configure' will replace with actual target
This line needs to be manually changed to
target=i386-next-nextstep3
Then everything is kosher. I would patch the configure program if I had
an inkling about how it works :(

As most know, NS User 3.3 came out before NS Dev 3.3. So there was a time
when IP multicast support was in the OS, but you couldn't write any apps
because the developer package didn't know about multicasting.
In the interim, NeXT posted a header file (mcast.h? multicast.h?) on
NeXTAnswers which appeared to allow one to write IP multicast apps with
Dev 3.2. Now that Dev 3.3 is out, this header file is no where to be
found.
I know that NS Dev 3.3 has multicast support scattered throughout various
header files, but since I don't have access to Dev 3.3, I am looking for
this multicast header file (designed for Dev 3.2/User 3.3). I want play
around a bit. Has anyone seen it lately, or have a copy lying around on
their machine?

Hi,
New to the Objective-C language, I've come across the following problem

The C++ class has as one of its instance variables a function of type
char *foo(int). I couldn't figure out how to declare this as a Objective-
C instace variable.
Does anyone know how to do this?

Hi,
the fix is relatively simple. Just have a look at the fragment of the configure
script below. You just have to swap the two first echo lines and exchange the
> and >> directives.
[...]
# Remove all formfeeds, since some Makes get confused by them.
# Also arrange to give the variables `target', `host_xmake_file',
# `tmake_file', `prefix', `local_prefix', `exec_prefix', `FIXINCLUDES'
# `out_file', `out_object', `md_file', `lang_specs_files',
# `lang_options_files', and `INSTALL_HEADERS_DIR' values in the
# Makefile from the values they have in this script.
rm -f Makefile.xx
rm -f aux-output.c aux-output.o md
echo "s|^target=.*$|target=${target}|" > Makefile.sed
echo 's| ||' >> Makefile.sed
[...]
This fix was suggested by someone else. (Sorry, can't remember the name.)
I have no idea why it is necessary nor why it works. Just use it.

The WorkSpace manager does not run until someone logs into the console of

What flags did you give to the compiler (or did the Makefile give) when
building? If it's POSIX source-code, then you want to give -posix always,
and -lposix when linking.
We just went through all this stupidity of POSIX when building SLiRP. My
first builds of SLiRP, which used -lposix, but NOT -posix gave EXACTLY
the same errors that you cite. The intuitive "Floating Exception", and
this NXCreateZone stuff when debugged.
The autoconf-generated "./configure" script in SLiRP ran POSIX source through
cc without -posix, so it couldn't get proper values for sizeof(),
couldn't tell if certain header files were POSIX-compliant, didn't know
if the machine was big-endian or not, etc, etc, etc...
I don't know anything about ssh, but if it uses a GNU autoconf-generated
configure script, it's probably filled the configure output with lies.

Yep, it probably means you are using the latest version of
the MiniSQLAdaptor and EOF 1.0. You will need EOF 1.1 to
use the latest adaptor. Otherwise you will need to find
an older adaptor,good luck, and compile and older version
of the msql database.

'one of its instance variables is a function'?
It's not quite clear, what you mean by this.
In C++ methods of a class are declared like it's IVars:
class Bar
{
int a, b;
double f;
public:
char* foo(int a);
};
char* Bar::foo(int a)
{
// do something
}
But methods and IVars are two different things in ObjectiveC. To get a
corresponding class in ObjectiveC, you would use:
@interface Bar:Object
{
int a, b;
double f;
}
- (char*)foo(int a);
@end
@implementation Bar
- (char*)foo(int a)
{
// do something
}
@end
If what you mean is, that one of the IVars of your class is a
function_pointer_, then you would use something like this:
@interface Bar:Object
{
int a, b;
double f;
char* (*theFunction)(int a);
}
- (void)setTheFunction:(char*(*)(int a))f;
- (void)useTheFunction;
@end
@implementation Bar
- (void)setTheFunction:(char*(*)(int a))f
{
theFunction = f;
}
- (void)useTheFunction
{
printf("%s\n", theFunction(100));
}
@end

as a C++ const? The former defaults to external linkage and its name is
available to the global scope, and the latter defaults to internal linkage
and its name is available only to file scope.
Is there freedom to chose one of the two, or is the compiler strictly
following only one of the two?

I suggest you look at alternative solutions. The IX kit in it's current
form will be discontinued and replaced by some foundation classes. If you
have EOF I suggest using it and a free SQL DB such as MiniSQL (on the
archives). For small quantities of data the simple NSDictionary should be
sufficient.

I have the impression that you are trying to archive a single object to
the typed stream, while changing its "value" during the process of
archiving. This will not work, as the archiver needs access to all
objects being written to the stream, to find back-pointers and so.
You can not, for example, free an object just after it has received a
-write: message. You can only free or change the object after the entire
operation of passivation has ended.
If this is an option for you, you might want to use a List of *distinct*
instances of objects of your class, each object with its own particular
value, then archive the list towards the stream.
Or you could archive just one object with "min","max" and "step" values,
so that the activated object is able to "replay" the situation as it was
before archiving.

Perhaps you don't need so much low-level access. Perhaps you could
override some method of a View or Window that handles keyboard input, then
incorporating a call to *super*.
The NextStep "Calculator" example (MinusPanel object) does so for the
method -(BOOL)commandKey:(NXEvent *)theEvent.

as an instance variable :
@interface Foo : Bar
{
char *(*foopt)(int); /* same as in C++ */
}
as a return type from a method :
- (char *(*)(int))getFoo
{ return foopt; }

- setFoo:(char *(*)(int))newfoo
{ foopt = newfoo; return self; }
read a good C ref. manual - it's all just the vanilla C type system really.

I agree that it's not a wise idea to build applications on top of the
Indexing Kit, but I disagree with the NSDictionary alternative that you
are suggesting.
It seems to me that the "maturity index" of NextStep objects is measured
by their prefix : objects without a prefix (View, Application, Window) are
very well thought out, brilliant stuff, can be relied upon. Objects with
the NX prefix (NXBrowser for example) kind of work, but can sometimes be
difficult to master. Foundation Kit objects (the ones with the NS prefix)
are not compatible with standard Objective C objects...
If you consider using an NSMutableDictionaryClassCluster (argh!), don't
forget to take a look at HashTable too.

For this kind of thing, it would be nice to have an Objective C
preprocessor at hand, in addition to NeXT's compiler (that is easier to
use during development). The NextStep program, once debugged, could be
translated to regular C, and then be compiled, together with your library
and the Objective C runtime, by an optimizing PA-RISC compiler.
There is no such preprocessor. Stepstone's is available for HP-UX but it
cannot compile non-portable constructs like:
@class NXImage, View;
@protocol NXWorkspaceRequestProtocol
(taken from appkit/workspaceRequest.h)

Organization: University of Alaska Computer Network
Message-ID: <408b29$43m@news.alaska.edu>
Keywords: fax modem driver mgetty NXFax
How does NeXTStep faxing work?
NeXTStep appears to support sending and receiving faxes.
There is a FaxReader application, and the Print panel has a
fax button. PrintManager allows you to create entries for fax
modems. However, NextAnswers say that, in order to send and
receive faxes, you need a special driver for your particular
fax modem. They give a couple of commercial vendors for such
a driver. One of these, Black and White Software (NXFax), has
a demo on the archives that supports sending single pages,
but not receiving--you need a license key to find out if
your modem/system combo will receive. Anyhow, I prefer not to
have third-party software watching my modem port if I don't
have the source code.
There are several freely available examples of fax software,
notably am (NeXT answering machine for ZyXEL fax/voice modems
which receives, but does not send, faxes), mgetty and sendfax
(generic UNIX). These seem to provide a solid foundation for
a freely available "driver" to work with the NeXTStep
software. But, I cannot find any documentation describing how
such a driver should be organized and linked, how it is
called by the Print panel, how (or if) it monitors the serial
port, and how it should format faxes for FaxReader.
If anyone could point me to the relevant documentation or how
to get it from NeXT, I would appreciate it.
Thanks

Hi -
You should download a copy of the "NormalBrowser" MiniExample
(available from ftp.next.com). It shows how to display rows
of data using the NXBrowser. The key elements are to become
the NXBrowser's delegate (a connection in IB) and implement the
method -browser:fillMatrix:inColumn:
> and get a selected (only one needed) row back.
>
There are a few ways to do this, depending on when you need
to know about the selectioin. You can find out right when
the user clicks on an entry by making your object the "target"
of the browser (settable in IB) and implementing an "action"
method to respond to the single-click.
>Please be as detailed as possible

Well, you're in luck (I suppose...). The NeXT programming environment
is based on ObjectiveC, not C++...

Please do no E-mail only.
Our institute is "desperately seeking" the best cross-platform
builder. XVT seems great , Galaxy looks better yet but expensive,
Wind/U is good but has not MOTIF look and feel.
Yes, I have PIGUI faq but what we need is real world experiences.
Good and bad.

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.

This sounds like VisualBasic or Delphi to me. Whenever I have to do
some work with VB, I hate it that there's no easy way to look at *all*
your code. I always wonder "where's this?" and "where's that?", so I
somehow don't like the paradigm that each and every function/method/whatever
is located in a different 'file' (quotes here, because on low-level all
those functions are still in a single text file, only the editor doesn't
display them as such).

Hi everyone. I've recently been getting into DBKit and have played with
the functionality that can be achieved within the Interface Builder.
However, I'd like some functional examples of programs which use the other
DB objects as well such as the DBQualifier and DBRecordList and so on so
that I can get an idea as to how they're supposed to be used.
That said, would anyone know of a site where I might be able to get some
sample code, or some information that would help me get started ? The
online document provides me of a good overview, but I'd really like a
functional program to look at.
Thanks for any help.

Or, you could link using the -ansi flag, which allows access to the ANSI-C

My answer, stated above, is totally out to lunch!! What must I have been thinging??
I thought that strdup was included with NeXTStep, but alas, it isn't.
I thought that I had better correct myself, before someone else did!! ]-)
Here's an example of another way to duplicate a string:
#include <stdio.h>
main()
{
char *string1, *string2;
string1="This is a test";
string2=string1;
printf ("String1 is: '%s'\n",string1);
printf ("String2 is: '%s'\n",string2);
}
As this shows, strings can be simply assigned to create the desired result.

You can use the NXBrowser object. You have to implement a delegate object
to fill the browser with data. I find the "lazy" delegates to be easier
to implement than the "normal" one. This is also mentioned in the
documentation, but I still had the reflex to choose for the "normal"
delegate first (thinking that the default choice would be the easiest to
implement).
Suppose you have an outlet (set in IB) to "aBrowser" with the delegate set
to an object of your own fabrication, with the "target" set to the same
object and action set to a method, called for example, "-browserClick:".
From initialization, e.g. -appDidInit, I call -setUpBrowser
- setUpBrowser
{
assert([aBrowser delegate] == self && [aBrowser target] == self);
[aBrowser getTitleFromPreviousColumn:NO];
[aBrowser setMinColumnWidth:1];
[aBrowser setMaxVisibleColumns:3];
[aBrowser setMinColumnWidth:50];
[aBrowser loadColumnZero];
return self;
}
If you call -getTitleFromPreviousColumn: then you will receive
-browser:titleOfColumn: messages.
- (const char *)browser:sender titleOfColumn:(int)column
{
assert(sender == aBrowser);
switch(column) {
case 0 : return "Chapter";
case 1 : return "Category";
case 2 : return "Section";
default : return "";
}
}
Sometimes "column" seems to be set to -1, so I implement a default value
in the switch.
Then you also implement the method,
- (int)browser:sender getNumRowsInColumn:(int)column
{
assert(sender == aBrowser);
switch(column) {
...
}
}
to return the number of rows in a given column. You probably want to find
out what row was selected in the *previous* column, you can use [[aBrowser
matrixInColumn:column - 1] selectedRow] for that.
Finally, you implement
- browser:sender loadCell:aCell atRow:(int)row inColumn:(int)column
{
}
to set the attributes of "aCell". If your "data" array contains string
values you can use [aCell setStringValue:] or [aCell
setStringValueNoCopy:]. You also use -setLoaded: and -setLeaf: and
perhaps -setEnabled:.
If you want some other "action" to be performed when the user is clicking
in the browser, then implement
- browserClick:sender
{
}
to do whatever is needed. You find the selected row and column again by
[aBrowser selectedColumn] and [[aBrowser matrixInColumn:aColumn]
selectedRow]. The column might be -1.

Hi there.
I have a problem with NXImage and Distributed Objects. Well, my
goal is to display the same NXImage in two views: the server's one and the
client's one.
I tried to access NXImages via proxies but even though the
client's view was "lockFocused" , the image appears in the server's view.
I tried something else by using NXBitmapImageRep. I tried to make a
copy of the NXBitmapImageRep on the client side. The NXBitmapImageRep was
encapsulated in an NXData object and then send to the client through the
method: - (oneway void) useABitmapImage:(bycopy in id)aBitmapImageData. The
image is indeed copied but it seems like I have no access to the bitmap
data.
Did I forget to do something? Can someone help? It would be great.

1) The NeXT compiler is able to translate C++ programs. I have
never used C++, so I cannot be more precise; but you should be able
to port your sources directly using C++, with no or only minor
changes.
2) Should you want to really transfer the source to 'pure'
Objective C, I would recommend to replace such functions by objects.
If not appropriate, you have to use plain C feature - the function
pointer. For example:
#import <stdio.h>
#import <stdlib.h>
#import <objc/Object.h>
static char *fnc(int i)
{
static char test[]="0123456789";
return test+i;
}
@interface Foo:Object
{
char *(*foo)(int); // type (*id)() is function ptr
}
-(char*)foo:(int)i;
@end
@implementation Foo
-init // set the function ptr
{
[super init];
foo=fnc; // <----
return self;
}
-(char*)foo:(int)i // use the function
{
return foo(i); // <----
}
@end
void main(int argc,char **argv)
{
id foo=[[Foo alloc] init];
printf("%d => %s\n",atoi(argv[1]),[foo foo:atoi(argv[1])]);
}

You have to be very, very careful of the circumstances under which you
do this. I spent hours and hours on a programming assignment tracking
down the weirdest bug, which was due to doing string assignment instead
of strdup(). The problem with this technique is that since string2 just
points to string1, changing the contents of one string will change the
contents of the other. Very frequently this is _not_ a desired effect.

I've had a bit of trouble compiling a C program with -posix on my NS3.2 box,
both when using cc and gcc 2.7.0. I'm not doing anything extraordinary; here
is a test program that illustrates the problem:
#include <stdio.h>
#include <time.h>
int main()
{
char foo[512];
strftime(foo, sizeof(foo), "%m/%d/%y", localtime(NULL));
printf("%s\n", foo);
return 0;
}
The commandline essentially looks like this:
gcc -g -Wall -D__USE_FIXED_PROTOTYPES__ -posix -o myprog myprog.c
At link time:
ld: Undefined symbols:
_objc_msgSend
_NXGetDefaultValue
_NXRegisterDefaults
.objc_class_name_NXStringTable
.objc_class_name_NXBundle
Since my program contains no Objective C code, the problem must be with a
library. It is easy to verify (via nm) that the offending function is
strftime() in libposix.a.
I can grab an implementation of strftime() from somewhere else, but--urk--I'd
rather like to be able to compile POSIX programs on my NeXT without
modification.

strdup is not an ANSI-C standard function, only an example (according to my
Kernighan&Richie 2nd. ed.). And even if it were ANSI, it would be available
without the -ansi flag as well.
Pick up your K&R manual and copy the example (p. 143, I think). Rod Ragner's
solution lacks a test for the value returned by malloc, although that would
only fail if virtual memory (of which there is only a few GB) is exhausted.
Stephen MacDougall's second advice (simple assignment) has limited
applicability: the original string must be guaranteed to continue to exist, and
any changes to it also affect the ``copy'', which is really an alias.

Sven,
We had a similar problem some time ago when we were putting together a find
panel. We could not find the source of the problem and assumed it must be a
Text bug. We did, however, get a work around - and it was connected with
ensuring a selection had been made in a Text object prior to invoking the
method.
Sorry I don't have the source to hand to give you exact details of the
workaround.

for( s=0; s< 6;s++)
printf("%x%c", addr[s]&0xff, (s==5?'\n':':'));
}
static char * ether_addr( name)
char *name;

static char ret[6];
struct arpreq a;

Of course, there are other systems that are missing strdup(), such as
Ultrix, so you might just want to include your own implementation.
I remember that when I wrote one under Ultrix, I had to hack it so it
would always malloc() at least 4 bytes (I was working w/ really short
strings), because of word alignment issues with the RISC processor.
A truly robust and portable implementation would have do the same.

Load your file into any drawing program that lets you export a graphic

Hello,
I have set up in IB 3 chained (through EOQualifiedAssociation) EOControllers
which display data in an NXTableView. Each controller displays data in one
column of that table view.
The first controller has a relationship to the second one and the second one to
the third one.
Now when I fetch the data from the database the first column is filled up
properly but the second column only shows one item and then an AlertPanel comes
up telling me that -[EOExpressionArray objectAtIndex:] tries to get an item of
an array that is out of bounds. This happens deeply into EOF code and INMHO is
not my repsonsibility.
Has anybody experienced this before and solved it?
I tried to find it in the ReleaseNotes but couldn't find any mention of it.

The form was most probably not written in postscritp - so check the original and see if the application
used to create it (it is listed at the beginning of the postcript file as "%%Creator ....", or, if
generated from the print command, you will find some other hint) can generate an eps.
If not, you can try hacking the ps file with a text editor. An EPS file will need a bounding box around
the whole thing.
%%BoundingBox: 14 74 813 563
where the figures are: the x and y position of the lower left corner, the delta x and delta y sizes of
the clipping frame around the item.
Furthermore, the header must be changed to
%!PS_adobe-2.0 EPSF-1.2 or something similar.

Hello everybody,
running NeXTStep 3.3 on Intel Architecture I met the following problem:
what is it for an obscure instance to decide which Application Icon
is assigned to a particular document type in the Workspace Manager ?
All my html Documents appear under the Icon of an appication that left
my computer already long ago; the html documents are opened correctly
by OmniWeb, but they always appear with the Icon of eText, I installed
some month before. The problem is not to link document types and
applications, but only the stubborness of some former icons in the WM.
Does anyone know how to fix this ?
Help would be greatly appreciated.

Does anybody have an idea why this happens ? I have a simple DO app, and my
client prints out this message and receives a timeout exception shortly
after.
Now the client isn't a appkit app but a deamon running in the background,
and I started the connection with a [con runInNewThread]. The server did
the same.
All they are trynig to do is to exchange a couple of integers in the

Message-ID: <40g0ut$a75@noc.tor.hookup.net>
There may be a simple solution/explanation to the problem I will describe below. If so,
could some kind soul please enlighten me?
The problem is this: I want to be able to continuously update a miniwindowImage to
display the passage of time. In other words, I want to be able to start a timer in a window,
miniaturize that window, and see the elapsed time in the miniwindow. I know this is
frowned upon in NeXT documentation, but it's an extremely useful ability to be able to
provide.
In my Timer class, I composite the elapsed time on top of a template image, then assign
that image to the appropriate button in the window, at the same time assigning the image
as the miniwindowImage of the window. Now, according to the documentation, if the
miniwindow is on the screen, it should update. Well, it does - the first time. From that point
on it stays frozen showing the elapsed time when it was minimized. The time passes
properly in the window's button. The timer _is_ updating the miniwindowImage (I did a
variety of tests), but the miniwindow somehow doesn't believe that the image has
changed, and continues to display the original image.
I was able to get around the problem by creating TWO images, toggling between them on
alternate seconds. This convinces the miniwindow to change its image. But I shouldn't
have to resort to this messy solution. Does anyone know of a reason for this behaviour?
The NeXT documentation for miniwindows is extremely sparse.
An interesting aside: as the miniwindow is updating, it sometimes "flashes" - probably
about half the time. Though not life-threatening, it _is_ aesthetically annoying. If anyone
can suggest a solution to this annoyance (somehow synching with the vertical refresh?
heh...) I'd appreciate it.
Please respond here, as my email address is not functioning at the moment.
Thanks in advance!

There doesn't seem to be any apparent way to initialize an NXBrowser with
multiple cells highlit. If you setMultipleSelectionEnabled to YES, a selectAll
will work, however, multiple calls to setPath are ignored and the only one
highlit will be the cell for the last call to setPath. There doesn't seem to
be any way to turn off selected ones, and the doc states
"Your code should never try to set a path or select items by sending Cell
selection messages to the Matrices in the NXBrowser's columns."
This doesn't work anyway, since a Matrix selectCell will also only highlight
the last cell referenced.
Can this be done any other way, or is it impossible to initialize a NXBrowser
with multiple entries selected?

I think that when you don't specify _any_ architechture with -arch, it
compiles a truly "thin" binary for the compiling platform.
If you give it "-arch m68k", it probably creates a FAT binary with only
one architecture in it. The overhead of the MAB structure probably
accounts for the extra size.

Actually, I thought that the calling conventions between the two compilers
are different especially with respect to small structs. I know at least, that
this was true for the first beta release of PDO3.0/HPUX and is probably true
for NS3.3.
Also, I thought that the stack grew the opposite direction in NS/HP than
it did in HPUX. Perhaps I'm thinking of Sparc?

Organization: Union Bank of Switzerland, New York site
Message-ID: <40im00$p0n@ns2.ny.ubs.com>
It's been a very long time since I have posted anything to csn.*.
There are a number of reasons for that, but that might be the subject
for another post ...
Anyway, for the past year I have been Beta Testing Objective-Tcl
(ObjTcl) from TipTop Software, in its various incarnations. Due to my
complete belief in the honor code of non-disclosure, I was not able to
share my thoughts on this product with *anybody* for the entire year
:-(. Now that it has been officially released, I would like to make
some very strong statements about this product. I am *not* affiliated
with TipTop Software in *any* way, and in fact, have never even spoken
to Pedja Bogdonavich other than via 100's (if not 1000's) of emails. I
am also an extremely happy customer of their TipTop (modem and
terminal) product.
To my mind, this is the single most important advancement to the
development process on NEXTSTEP (NS) since the MiscKit (MK). The MK
was (and is) fantastic on many levels, possibly the most important one
being the standardization of many very common tasks, e.g.
multi-windowed doc management (actually thanks to Mike Ferris and
MOKit for this abstraction). As wonderful as MK is, it is really
mostly a major (really major!) time saver, rather than a new paradigm
for developing software on NS.
ObjTcl is (or certainly can be if we use it creatively!) a new
paradigm for creating software on NS. For those who missed the
announcement, most briefly, ObjTcl is both a full blown Objective-C
(ObjC) style interpreter, and, an embeddable interpreter (within ObjC
programs) which allows 100% transparency between ObjC and ObjTcl via
the ObjC runtime. In other words, one can not tell whether classes,
methods, etc., are written in ObjC or ObjTcl.
I believe that it is a paradigm shift for NS developers, and as such,
a very few will see it and instantly think "Unbelievable, I can think
of 100's of things I can use this for ...", while most will think
"Cute, an interpreter ... now let's get back to work!". I mean no
disrespect to the second group of folks in making that statement. I
think that most of us are busy trying to get our jobs done, and if a
new "tool" does not strike us as immediately useful in our current
assignment, we tend to dismiss it. This is natural. This is why I am
taking the time to expound upon some of the virtues of ObjTcl, so that
some of you (hopefully more than just some :-)) will stop and take a
little more time to look at it than you might have otherwise.
First, let's start out with the licensing. The package (unlicensed)
will allow you to do everything you could do with a licensed version,
though it might get annoying (with prompts and reminders, etc.) after
a while. This, therefore, leaves no one with an excuse for not trying
it out (except for the other excuses that is :-)).
OK, Hadar, enough *background*, what's so special about it? Well, I
mentioned two strong points above (there are more, like IB
integration, etc., but let's ignore them for this post!!!), and I will
deal with them each in turn.
1) An ObjC style interpreter.
What I mean by "ObjC style" is that it is not 100% the same syntax as
ObjC, though there are tremendous similarities. It would have been
nice to have the syntax be identical, but the fact that the
interpreter is TCL, actually gives it enough advantages over normal
ObjC stuff, that net net, I really think that the advantages outweigh
the disadvantage of having a slightly different syntax.
First, a trivial example, then a slightly more interesting one:
a) Here's a simple session from the objtclsh (command line ObjTcl
shell). It is a little long, and I don't want to interrupt the flow
with commentary, so I will make a few comments *now* and you can
follow along below. First, I create a new instance of Object. I then
ask that instance if it is a kind of Object (and it responds TRUE). I ask
it if it is a kind of Window, and it responds FALSE. I then ask it if
it is a kind of Hadar, and the debugger intercepts, telling me that
there is no class with the name Hadar defined, and it gives me a
chance to CORRECT that problem right now. I choose not to, so I
continue, and the error is returned to me. (You can enable or disable
debugging.) I then CREATE the definition of a class Hadar
interactively, with one instance variable, and two methods. I then ask
again if the instance of Object is a kind of Hadar, and this time,
instead of being an error, the answer is simply FALSE. Lastly, I
instantiate a new Hadar object, and send it the name method (and it
behaves as expected). Pretty simple, and yet powerful. Here it is:

OK. You say this is cool, but how do I get anything *real* done like
this? Two quick answers, a) obviously anything you can type
interactively, you can also put in a file so that you can build up
complex programs rather easily while testing them along the way, and
b) you can include complete libraries in the interpreter as well, so
you can test (and or develop) significantly more *real* things than
the above trivial example.
There are two ways (other than adding your own custom classes as we
just saw) to extend the interpreter. You can create a *custom
interpreter* by simply linking the 5 line example main program with
*any* libs you want to be automatically included in your interpreter,
*or*, you can *dynamically load* any libs that you would like. I will
give a complete example of the latter, which can be used, for example,
to test out the functionality of a Kit! In this example, I will show
you everything you need to do to interactively test the MiscKit! I
will leave the commentary out as it should be self-explanatory:

The above example is *complete*. There is some line wrapping going on
from my paste in the terminal (TipTop :-)), sorry, but that is where I
actually turn the libMiscKit.a into a dynamically loadable file,
misckit.O (obviously the name is arbitrary). The warning messages for
Couldn't find default font are due to the fact that there is no
Application Object in this interpreter (though there could have
been!!!). Clearly, while this is a *very* powerful tool for learning
things like the MiscKit (or any kit), it is particularly useful to us
at UBS for doing things like verifying that new apps are using our
analytic libraries correctly. When results don't appear to be correct
in the UI of a new app, one can fire up an objtclsh (with our libs
pre-linked, or simply dynamically loaded) and test the results with no
UI and known parameters to see if the results are correct at the
library level. Most often they are :-), and the developer can
concentrate on how he/she mismatched the user's desired inputs with
the actual calling syntax of our models :-)
2) The interpreter can be embedded in any ObjC program. I will not
give any direct examples of this, and I will further muddy the waters
by telling you that this is the conceptually harder part (though the
much bigger win part as well!).
This is much harder because there are too numerous ways for you to
decide exactly how/when/why you will give access to ObjTcl. For
example, in some of our apps, we include *one* line of source (and one
header file :-)), and all we accomplish with this is that we embed an
interpreter, and *ask it to publish itself as a Distributed Object
Server!!!*. The remainder of the app is untouched. Now, when the app
is running, we can use a different command line program, dosh, which
is essentially an "objtclsh" with no interpreter in it. It merely
connects (via D.O.) to an already running interpreter (across networks
if desired, *of course, it's real D.O.!!!*) and can now be used to
"examine" the running app (ala gdb, but the app is actually running,
not frozen at the breakpoint!!!), and/or *change* the app, via
Category definitions, new classes, etc.
We have apps that range in ObjC-ObjTcl mixture from 20 lines of ObjC
plus 1000 lines of ObjTcl, to an app which is 44,000 lines of ObjC
plus 100 lines of ObjTcl. Again, the hardest problem is determining
exactly what level of control you wish to give the user, whether you
wish to "call" ObjTcl to perform very specific functions, or whether
you wish to permit a completely open design where it is unknown and
transparent whether something is written in ObjC or ObjTcl.
Lastly (I promise), the seperate product Objective-Browser (OB) is so
amazing (and extensible!!!) that it alone justifies purchasing ObjTcl,
just to run the Browser!
I can not stress enough that if you are building NS Apps, and do not
take a look (a serious one at that!) at this product, then you are
doing yourself a serious disservice! If this were a product that we
developed in house, we would be guarding it so jealously that I wonder
at times why I was busting at the seems to discuss this with
people outside of UBS for the past year. However, we did *not* develop
it, and we *do* use it heavily, so I would rather see it thrive, have
others deliver software to *UBS* that uses it, and have it continue to
evolve. Hence, the evangelism. Enjoy it!
If there is enough traffic warranting further examples, etc., then I
will consider putting out some more stuff.

I had exactly the same problem. This is obviously something, that NeXT didn't think about.
Unfortunatley, in OpenStep it's the same.
When you read the documentation, you will find two methods (in Matrix), that deal with selecting
cells.
- selectCell: and friends. These select a specific cell, but deselect all previously selected cells.
Well, I thought. the Matrix is probably in RADIO_MODE. But no, it's the same in LISTMODE and all the
other modes :-(
- selectAll: Selects all cells. Not what I wanted.
After I while, I found a third method, setSelectionFrom:to:anchor:lit: and voila, when using that one,
the previous cells are NOT deselected. Strange, eh ? It's definitely not in the documentation.
Oh, before I forget, instead of using setSelectionFrom:to:anchor:lit: multiple times to set your
cells, you could also use the MiscSelectionMatrix in MiscKit. It does exactly what you want.
Did anyone Bug_NeXT about this ? If not, should we ?
so long,

This is a good question. For one, the Objective-Browser, which requires
the ObjTcl from TipTop :-), is something that really needs to be used to
be appreciated. Second, and I admit that I stopped looking at the free
stuff (of which there were at least two if I recall) a *long* time ago,
there were things that they simply could not do that this one can.
When I last looked, you could *instantiate* objects, but could not *define*
them (in other words, create classes, create categories, etc.) on the fly.
That may indeed have changed since I last looked.
Another factor is the seemless support for Distributed Objects (something
that we use heavily, but others might not find as useful). Built in
"interactor" support, so that you may give your users access to ObjTcl
without writing any UI for that piece (not a big deal, but every little
bit helps). IB support (which I don't think is in any of the PD stuff).
You can do some pretty amazing things in IB with ObjTcl, and in fact can
control IB through the D.O. support, which is pretty hot stuff. It permits
you to *automate* a lot of mundane IB tasks (I purposely left out the IB
stuff from my last post, and maybe I shouldn't have :-). As far as IB
automation is concerned, one of the examples, Examples/ObjTcl/EOF-IB
came from UBS directly. It shows how easy it is to automatically
connect an EOController to an NXTableView with *no* ctrl-dragging for
each association!
I could probably go on, but your question is a valid one, and if the
only thing that ObjTcl does is excite people to the possibilities, and
then the PD versions get better, then so be it (sorry Pedja :-). I for
one, would rather use them *now*, have them from a vendor who has
demonstrated high quality software for a number of years, coupled with
high quality support, and at the prices he's offering the product at,
I consider the investment as close to PD as commercially possible
:-).

Hello everyone,
I have just had the unfortunate pleasure of crashing my hard drive
beyond, or seemingly beyond, repair. First of all, I am running NeXTStep
3.3 on a Pentium 90. I crashed after ejecting a Macintosh disk from my
machine. Some idiot marketer at NeXT decided not to CLEARLY notify users
of this problem. The worst is that I bombed the machine once, called tech
support to tell them exactly what happened (ejected Macintosh disk), and
asked if this was a known problem because I had it happen once before. I
was told that there were no known problems. I was able to restart the
machine after this crash and proceeded to try this again, ejecting a Mac
disk, on the advice of the tech support department. This time, the
machine crashed so hard it could not recover. Now I call tech support and
get someone else who tells me that this IS a known problem. Too fuckin'
late folks. Now, I can't even reinstall NeXTStep because it appears that
the boot blocks and labels have been wiped from the drive. However, I'm
not entirely certain if my problem is only software related. The drive
and the machine are only a couple of weeks old, so my initial assumption
is that I have a software problem. I am able to boot up in a single user
mode from a floppy and CD-ROM and get to the '#' sign. From here, I can
execute all commands with root priviledges. I am definitely not familiar
with most of the disk utility commands built into unix. All of my
information has come from the man pages. My first reading of the man
pages led me to attempt a 'scan' of the disk using the interactive mode of
the 'disk' command. I executed the following command 'disk -l mydisk
/dev/rsd0a. The hard drive failed to respond on 7 or 8 successive tries
to access it. Finally, the process aborted itself with 'FATAL ERROR'.
This left me at the 'disk>' prompt from which I attempted a 'scan'. This
returned 'get label: Invalid Argument'. I've attempted to use 'fsck',
again without luck, and a few other commands which are not worthy of
note. At this point, as I have mentioned, I cannot even reinstall my
software. I have a full days worth of work and some other important files
which were not backed up and would really like to recover anything that is
still available. If anyone has any suggestions, I would greatly
appreciate your help.
Thanks,
Paul

I'm replacing my getty program with my own version. The problem is that
when I replace the getty process with the login process (via execv)
the login program screws up.
More precisely, when the login program runs it prompts the terminal user
with 'password: ' (the users name has already been passed to the login
program as a parameter when the getty called login). If the user types in
their password here the password is echoed to them. What is more is that
all of there input is being ignored and echoed back to them. Further
investigation showed that login was not taking input for the password from
the terminal user, but rather, it was taking it from the terminal in which
getty was originally run.
Essentially, when login prepares to receive the password it should simply
receive the characters from the terminal user and not echo them. But, what
is happening is that the login program switches from receiving input from
the users terminal to receiving input locally from the terminal in which
getty was originally executed.
ThanX in advance guys (non-gender specific here) !

Why can't you just setState; the cells when you load them. The above
method assumes you have a continuous selection in mind.

But I can't rsh to the cube from the sparc, but I can from the

cube since I can't rsh from the cube to itself either.
Permission denied is the reply. I've scoured /etc/ and netinfo,

As a budding NS'er, I got some much-needed help from this group a week or so
ago on a DO problem I was having. I thought I'd troll again for some
comments/opinions:
I've seen the "MiscKit" mentioned here a couple of times. How can I find out
more about it? Also, are there any more must-haves (or just nice-to-haves)
for someone who's trying to build a good NS generalist's toolbox? Classes, ,
neat IB controls, etc...shareware would be great, but decently-priced stuff
counts, too.
I appreciate everyone's thoughts (and, as a beginner, their patience :-))

easiest is the following:
index string framebuffer name slot unit romid x y width height maxdepth
^^^^^^^^^^^
index is obtained by countframebuffers.
another one gives you the screenlist (i.e. array of windows) where the backmost
is the workspace window (?):
currentcontext
countscreenlist % find out how many windows
array % create array to hold them
currentcontext screenlist % fill it in
or as a shortcut:
workspaceWindow currentwindowbounds
(but this is very Next specific)
hope this helps,
George

Because Matrix doesn't know about it. Try it, and then ask Matrix
getSelectedCells: and it will return nothing.

Subject: [EOF] Q: creating/updating/accessing objects
Date: 13 Aug 1995 16:52:53 GMT
Organization: Institut fuer Informatik der Universitaet Muenchen
Message-ID: <40lal5$jvv@arcadia.informatik.uni-muenchen.de>
Hi everybody,
here are some things about EOF, that I don't understand.
First, how do you correctly create a new object ?
Well, I tell my dataSource to createObject, set the primary ID of the new object, and insert it
into the dataSource. But when I change the data of the object, and want to update it later, I get
all kind of errors.
I figured out, that all attributes are set to NULL by [dataSource createObject]. Now when the
object is saved, and reloaded, all these NULL's change to [EONull null]'s. But the low level EOF
routines, that unique objects don't consider NULL and [EONull null] the same, so they don't
recognize the object they just fetched from the database as the one, they still have in memory.
So I made a category of DataSource (I just LOVE categories, have dozens of them :) called
smartCreate, which set's all properties of the new object to [EONull null]. Problem is, that it
only knows the class of the new object, but it needs the model, where this class is used, in
order to find out which properties this object has.
Next problem. How get relations and flattened attributes updated ?
I have an object A:
{
int ID, // my primary key
int B_ID, // id of some object B
id to_B // 1-1 relation to B, using "A:B_ID = B:ID"
}
and object B
{
int ID
}
When I access to_B for the first time, it is still a EOFault, so it uses B_ID to fetch the real
object from the database. After that, to_B is simply a object of class B.
Now I change B_ID. But how do I tell the system, that to_B is now obsolete, and needs to be
refetched ?? I couldn't figure out how to do this in general. I tried updateObject, saveObjects,
saveToDataSource, refetchObject, forgetAllObjects, etc.....
At sometime, I got it to work in a specific routine, using the right combination of the above
calls. It didn't work at other places in my progem :) I simply decided to never touch it again
:)))
Little bit more difficult problem. Assume I have a 1-n relation instead of the 1-1. Now to_B is
an NSArray, and instead of B_ID in class A I have A_ID in class B. easy.
Now I fetch to_B and get an array of 5 B's. Then I change the A_ID of a sixth B to match my A
object. This new object now should show up in the Array.
- How do I do this at all ? which of the various controllers and datasources do I have to
update/save ?
- How do I know that I need to do the above ? I mean, somebody is changing this A_ID behind me
back (let's assume this somebody is me. Bu it could be another user). How do I know that I need
to trigger that refetch ?
It seems to me, that the only way to achieve the second, is to use delegates of EOControllers all
over the place, which control all update/fetch/delete/insert operations, and update all the other
controllers according to what their own controller just did. This doesn't sound very easy to do.
And it soehow seems to be in the wrong place. All the information, that is needed to do this is
already there, in the model. Putting it again in the controller delegates doubles the work.
Third:
Accessing data using EOGenericValue or using objects.
When using GenericValue's, you use setObject:forKey and objectForKey: to access the data. When
using objects, you can't use these anymore, you have to use the accessor methods.
Why isn't this already there ?
@implementation NSObject (EOKeyValueCoding_singleProperty)
- objectForKey:(NSString *)aKey;
{
return [[self valuesForKeys:[NSArray arrayWithObject:aKey]] objectForKey:aKey];
}
- (void)setObject:anObject forKey:(NSString *)aKey;
{
[self takeValuesFromDictionary:[NSDictionary dictionaryWithObjects: &anObject
forKeys:&aKey count:1]];
return;
}
@end
Well, I think I have written enough, I should get back to regular programming....
Thanks for any ideas on this.

Check out Tiggr's FAQ for comp.lang.objc. As to the MiscKit, well, it's
the biggest piece of junk ever created. [Ha ha! Just a little joke,
everyone, so I could see Don's eyes pop out of his head] No, actually the
MiscKit is a must-have for the budding NeXTSTEP developer. It's got a
lot of great objects and tools [especially sound objects--hint, hint], but
most important, it provides access to a community which can give you a
lot of relief from the frustration of developing, even in as nice an
environment as NeXTSTEP. Point your www browser to

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

[from the document ftp://ftp.next.com/pub/NeXTanswers/1000_Help]
Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.

I experienced this problem with SGI's and NEXTSTEP Intel. I think it went
away when making .rhosts readable/writable by owner only, which NEXTSTEP
seemed to require, for security reasons.
Please correct me if I'm wrong, as I only *think* the problem was solved
after this change... It might very well be something else because at the
same time, there was an upgrade from NEXTSTEP 3.2 to 3.3 at that site.

The examples for parser are very rare (I found no examples at all)....
Now I'm hanging :-(
[cursor setKey:myKey andLength:strlen(myKey)] will find no key in a

What do I have to initialize before the query?
Are there any examples around?

The new versions of the MiscKit will use the Foundation Kit, and not
duplicate the effort anymore. All MiscKit classes that are Foundation
Kit like will probably be used for GNUStep.
/ Is going with MiscKit a good decision?
Yes, there are many useful classes.

The only way you will correctly build POSIX compliant programs under NEXTSTEP is
to use:
cc -posix -g -Wall -o myprog myprog.c
You cannot build gcc and use it for POSIX builds unless you understand the
difference between /lib/crt0.o and /lib/posixcrt0.o, and you are familiar with
the different link environments which result.
BTW, you cannot combine "-posix" with any AppKit stuff anyway, since the AppKit
makes assumptions about its environment which conflict with POSIX....

Message-ID: <40nq3l$pk0@shelob.afs.com>
Pay no attention to those awful people in c.s.n.advocacy who say the
NEXTSTEP market is history. AFS has two immediate openings for project
extensions at existing customer sites. Both are portfolio management
companies; one primarily equities, the other equities and arbitrage.
Experience in these areas is a plus, but not a requirement. We expect
to do some training, so "smarts" is just as important as knowledge.
These are not senior positions -- we already have project leaders -- so
the main requirement is an enthusiasm for NEXTSTEP programming and at
least a year of broad exposure to the environment. Also, you must be
willing to relocate to suburban Philadelphia as a permanent full-time
employee. Consultants will NOT be considered for these positions.
Recent graduates looking for their first big break WILL be.
For consideration, please send a resume with a brief summary of your
relevant experience and salary requirements to <greg@afs.com>. These
projects are ready to roll, so don't delay!
ABOUT ANDERSON FINANCIAL SYSTEMS
Anderson Financial Systems Inc. is a privately held software development
company based in Springhouse, Pennsylvania (suburban Philadelphia).
Founded in 1982, the company's primary business has been designing
customized trading software for more than 60 Wall Street firms on MSDOS
and NEXTSTEP platforms. Representative clients include First National
Bank of Chicago, PaineWebber, Dean Witter, Soros Fund Management, Delaware
Management Company, Oppenheimer Management Corp. and Texas Commerce Bank.
Since adding NeXT to its roster in 1991, AFS has made a substantial
commitment to building applications that leverage the unique capabilities
of the NEXTSTEP operating environment. In addition to trading systems, AFS
also produces WriteUp(tm) and PasteUp(tm) -- the leading word processing
and page layout applications for NEXTSTEP -- and distributes TIFFany, the
leading image manipulation program.

actually, it *is* in the Matrix documentation...
setSelectionFrom:to:anchor:lit:
-- begin quote --
- setSelectionFrom:(int)startPos
to:(int)endPos
anchor:(int)anchorPos
lit:(BOOL)flag
Programmatically selects a range of Cells. startPos, endPos, and anchorPos are Cell positions, counting from 0 at the upper left Cell of the Matrix, rows before columns. For example, the third Cell in the top row would be number 2.
startPos and endPos are used to mark where the user would have pressed the mouse button and released it, respectively. anchorPos locates the ªlast selected Cellº with regard to extending the selection by Shift- or Alternate-clicking. Finally, lit determines whether Cells selected by this method are highlighted.

Hi,
I just started using the MiscKit. I used IB to put together a simple app with
no code just some of the MK pallette objects in a window to see how they
worked. Anyway, When I try to build the app with PB I get errors, and I'm
not sure what I am doing wrong. Here is the error.
ld: can't locate file for -lMiscArrowButton
***Exit 1
Stop
***Exit 1
Stop
Now, I have placed the libMisc...a files in the project and made the headers
available but maybe I did it worng??
Thanks in advance

I guess, you have only NS partition on the disk. I that case use 'disk
/dev/rsd0h' instead of 'disk -l mydisk /dev/rsd0a' and than try 'scan'.
If scan finds the backed-up boot block, use it with -b option to fsck.
If you need more help, please, let me know.

does anyone know how to forward-declare classes in objective-c?
I know I can use 'id,' but am looking for a better solution.
Your help would be greatly appreciated.

Simply use the @class directive, e.g.: @class someClass;

Systematically using "id" *is* the better solution. If you know in advance
"what type a certain object is", you can express that using an "assert"
statement (together with more important assertions).
Using "id" makes your Objective C code elegant and concise. You will not
have to worry about the portability of @class and other directives.
In my Computer Algebra Kit software (http://www.can.nl), I'm using "id"
only (after a few years of struggling with static typing, categories and
protocols).

But be careful: There might be a paradigm change in the near future. If you
are using "id" only, it will be more difficult to upgrade your application
to OpenStep or NEXTSTEP 4.0. Static typing is one of the "new" concepts of
the OpenStep API.

And the NeXT-step is using C++ as the language of choice.... *no thanks*.
Part of the power of obj-c comes from the fact that it is no static typed language.
Of course the API will change. Does that mean we all must change our way we
think about programming...?

Did you actually try this on my sample program? For me, at least, it choked
in the same way gcc 2.7.0 did:
titan: ~/tmp% cat myprog.c
#include <stdio.h>
#include <time.h>
int main()
{
char foo[512];
strftime(foo, sizeof(foo), "%m/%d/%y", localtime(NULL));
printf("%s\n", foo);
return 0;
}
titan: ~/tmp% which cc
/bin/cc
titan: ~/tmp% cc -posix -g -Wall -o myprog myprog.c
ld: Undefined symbols:
_objc_msgSend
_NXGetDefaultValue
_NXRegisterDefaults
.objc_class_name_NXStringTable
.objc_class_name_NXBundle

I must admit that I've paid no attention to such issues. Other than
strftime(), things seem to work properly. Trying:
titan: cc -posix -g -Wall -o myprog myprog.c -nostdlib -lposix
resulted in _environ (as well as the items mentioned previously) being listed
as undefined. Is is sufficient just to link with /lib/posixcrt0.o, and not
link with any system libraries other than libposix.a?
> BTW, you cannot combine "-posix" with any AppKit stuff anyway, since the

That makes sense; but why would NeXT's POSIX strftime() implementation rely on
NXBundle and NXStringTable?

Now ObjTCL seems to be a very good product it still
raises the question what language an integrated interpreter
(embedded in IB) should use.
There was a discussion on gnu.misc.discussion in 1994 about
the choice of the gnu extension language and they choose a
different kind of language (Scheme, IMHO a good choice).
See http://minsky.med.virginia.edu/sdm7g/LangCrit/Tcl/ for
more information about the 1994 language war.
Please try to understand my point, I really don't want to bash on
ObjTCL, as Pedja has undoubtedly made it a good product. I just
want to raise the question "Why using TCL for this?"
Why not using an objective-c interpreter (or ... )?

This is an ideal introduction for a major flamewar, one I'll dodge.
I will say, though, why I'm using Tcl as a scripting language for a
non-NeXTstep Objective C system I'm developing. Tcl works. It's a
mature, functional product. Given the current lack of alternatives,
this makes sense. Now, when Guile comes out I'll be all for shifting
to it.
But the real reason I'm posting is to see if anyone out there is using
libtclobjc. If so, could you drop me a note? I'm in the process of
producing a minor revision of libtclobjc, and want to hear from other
users of the library. Changes I've made are a new configure script,
minor change for Tcl 7.4, and a couple of extra methods to Tk.m to get
access to Tk data structures.

KBNS.33.1.009_o3.2o How to programmatically select multiple cells, or a cell
which is not the first with that name in its column?
Description: See title. The only methods which allows one to set a selection
are -setPath:, which does not allow for the cases specified in the title, and
-selectAll:, which does just that.
How to verify: Read the documentation, especially for -setPath:.
Urgency: Does no damage, is rather obvious (the problem is!), easy workaround.
Confirmed: Raf_Schietekat (o3.2o, reported)
Workaround: Use -[Matrix setSelectionFrom:to:anchor:lit:] on the matrix
obtained for the desired column (using -matrixInColumn:).
Cure (for NeXT): Document this in a prominent location in the NXBrowser
documentation, including why it works (reassuring the programmer that NXBrowser
indeed relies on Matrix to remember this---if that is the case).
Report history: Discussion on c.s.n.p in 1995-08.
Comment: Is the selectedCell ivar actually a List of them (not tested)? If not,
where is the information stored? And what about delegate methods, or are they
only invoked for GUI-initiated selection setting (and -selectAll:, setPath:?)?

Also not to get into a flame war, even if GUILE were mature, stable,
well received, etc., do you have a version that *is* integrated with the
runtime?, that *is* integrated with IB?
Again, I do *not* want to flame, but I *do* want to get *work* done *today*!
ObjTcl let's me do that better *today* than I could *yesterday* without it
(OK, that's a lie, I have been using ObjTcl for quite a while, and therefore
it has been helping me for longer than just yesterday :-)).
Oh oh, and I *really* do mean it when I say that I don't want to start a
flame war here ... but:
While I understand the religious ferver that people ascribe to Perl vs Tcl
wars, Scheme vs Tcl, etc., I will point out that ObjTcl does not suffer
from *all* of the normal "one language vs another language" problems. We
must keep in mind that ObjTcl has full ObjC standing behind it, and Tcl is
merely *glue*. In other words, you do not have to write 10000 line ObjTcl
programs that are pure Tcl! You might have 10000 lines of ObjTcl (possibly
with zero Objective-C behind it!), but you have the richness of *types*,
a *runtime*, with *instances*, etc., so it isn't exactly Tcl either ...
Please forgive me, and don't explain to me why GUILE is better anyway,
unless you also show me how to leverage my current ObjC libraries with it
:-).

Hi all!
I am trying to display floats in a NXTableView. They display
all right, but I want to format them so they are exact in two digits.
So when I have a float value of 3.3333333 I want the NXTableView to
display it as 3.33 and if I have a float value of 3 I want it to be
displayed as 3.00. How Do I go about it? I don't have any idea how to do
it so I would appreciate very much any help.
Thanx
Chris

Hello,
Does anyone know of any good examples out there using DPSAddPort / msg_receive(). I am
writing some client code that wants to receive data from an image processing server when the data
is available, and be free to do other things while waiting for data. I am assuming that
DPSAddPort() is the proper way to do such a thing, but can be persuaded to accept better methods.
Thanks.

What is libguileobjc?
=====================
I have implemented glue that lets you send messages to Objective-C
objects from GUILE. It can pass and return long, int, short, char,
float, double, and Objective-C objects.
This is an early release---far from polished or complete.
It adds the following new primitives to GUILE:
(objc-lookup-class class-string) ; returns class object
(objc-id? any)
(objc-classnames) ; returns a list of class names
(objc-msg-send receiver method [args]...)
and a macro the handles the quoting of method names:
(objc-send receiver method [args]...)
It uses the functions in libobjects' mframe.m to construct method
calls on the fly (the same mechanism as used by distributed objects).
For example, you can do things like:
(define foo (objc-send List new))
(objc-send foo addObject: (objc-send Object new))
(objc-send foo addObject: (objc-send Object new))
(objc-send foo addObject: (objc-send Object new))
(define bar (objc-send foo objectAt: 1))
(define count (objc-send foo count))
(objc-send foo replaceObjectAt:with: 1 (objc-send Object new))
What's new?
===========
Libguileobjc version 0.2 compiles with guile-ii. Version 0.1 was
based on guile-i.
Where can you get it?

Essentially, what Tomas has done here is fix up my code a bit. In my
haste to write an example, I used the incorrect line:
+ strftime(foo, sizeof(foo), "%m/%d/%y", localtime(NULL));
Nonetheless, the error that I'm having is not a runtime error involving
localtime(), it's a link error involving strftime().

Jesus... is it _so_ difficult to understand the Objective C static
typing is _utterly_ different from the C++ one?
- in ObjC, you have late binding everywhere, even with static typed
expressions;
- the only consequence of static typing is improved _compile time_
warning list;
- so, should you replace _any_ 'SomeClass*' by 'id', the compiled
program will remain _unchanged_; only there might be less warnings
when you compile it.
An example for clarity: give a declarations
id v=[View new];
View *vv=[View new];
ScrollView *sv=[ScrollView new];
id h=[HashTable new];
HashTable *hash=[HashTable new];
[v display]; // this is compiled _EXACTLY_ same way...
[vv display]; // ... as this! So, in the next sample...
[sv display]; // ... will be used ScrollView's implementation!
// here's the _ONLY_ difference:
[h display]; // NO warning, runtime error
[hash display]; // _COMPILE TIME WARNING_ (if ignored, runtime error)
And once more: if you know the variable should be, say, _some_
Control, declare it as such: Control *foo! It might be Control
instance, Button instance, Slider instance, Form instance - all
right, _NO_ C++ static typing occur, polymorphism and late binding
works as usual. Actually, the variable _CAN_ contain even
non-Control object, but the compiler gives you a warning (if
possible) to remind you this probably was not intended.
On the other hand, should you use a variable for really unknown
object, use an id; this will work perfectly even with statically
typed methods (eg in OpenStep). Give a declarations
-aMethod:(SomeClass*)p;
id o;
[x aMethod:o]; // is _PERFECTLY_ valid...
Sorry to all - probably it is absolutely clear and I am only
repeating something anybody understand... But the quoted article was
not the first one which messed up the Objective C static typing
with the C++.

I am having trouble with the following code:
- revert: sender

const char *enableState;
const char *appName = [NXApp appName];
[remoteHostName
setStringValue: NXGetDefaultValue(appName, "RemoteHost")];
enableState = NXGetDefaultValue(appName, "Enable");

const char *machineName = [remoteHostName stringValue];

NXWriteDefault([NXApp appName], "RemoteHost", machineName);
NXUpdateDefault([NXApp appName], "Enable");
NXUpdateDefault([NXApp appName], "RemoteHost");
return self;
}
The trouble I am having is that the enable is being set fine in the database,
but the remotehost variable is not being set properly. I have tried placing
the [remoteHostName stringValue] in the NXWrite statement but that still doesn't
work right. This code is in a preference nib with dynamic view loading. I
extracted this code from the Developing NeXTStep Applications book by Gene
Backlin. I have checked the remoteHostName link in the nib quite a few times.
I am totally stumped on this because it is so basic and yet half of it works
and the other doesn't. Any help would be greatly appreciated.

[crunch]
Three things:
First: malloc use several bytes before the pointer to do
housekeeping, so if the request are less than a page-size, all the pages
are going to be flagged dirty, and the malloc should fail before
exausthing VM (unless, of course, you have several GB of swap avalaible)
Second: the malloc test will never fail under NEXTSTEP, *with
normal limits*
/* This program will never stop */
#import <stdio.h>
#import <stdlib.h>
main()
{ int i=0;
while (1)
{ if (!malloc(1000))
exit(0); // Success :-)
if (!(i++%1000))
{ printf( "%d\r", i-1 );
fflush( stdout );
}
}
}
/* The machine will have to be rebooted */
Warning: Do not try that on a machine with less than 2GB of swap space...
(Don't even try it on a machine with 2GB of swap space....)
Third: it is a bad idea (tm) to name the replacement function
strdup, first: because this is likely to cause link failure on future
release of NS (unless it is a #define, but this is equally dangerous if
you include system headers after your declaration (unless NeXT #undef
strdup before declaration)), second: because all functions beginning with
'str' are reserved by C standard (if I remember good), so non-standard
strdup could become standard with differents arguments (althought this is
really unlikely).

No, the war is over. No need to reheat it, as you and everybody are
free to choose whatever language seems fit for the problem at hand.
I do not deny the fact that TCL is stable, mature and avaiable. All I
do is deny TCL the right to be declared as the final solution for all
situations and problems. I have not worked with ObjTCL yet, it is
quite possible that in this context TCL is a good solution.
I just liked to hear your opinions. Having now a working product
based on TCL does IMHO not imply to stay with TCL for all times.

I have to apologize, guess some hours bugsearch in someone

Can you see why login screws up in this code?
I have here a test program of my problem.
When login prompts for the password it stops receiving input from the
intended terminal and reads it from the terminal in which this program
was executed. Can your see why?!

If you can find the source, please send me a copy! I think, however, you
are referring to /NextDeveloper/Demos/ShowAndTell.app that shipped in 2.0.
We used it at Lotus for creating demos of Improv. We even tried using it
as a front-end test tool (which is probably what you are looking for.)
On that note, I've contacted both Bill Tschumy (Otherwise Software) and
Doug McClure (Thoughtful Software) about doing such an app. I'd really love
to see one though it's unclear whether it would generate any revenue.

What is the difference between static typing and using assertions? Obviously
static typing is not required as in C++, which cannot work without it (even if
only using virtual methods). So static typing is merely doing specific kinds of
assertions that are visible to the compiler, which can then test them at
compile time, saving cycles, and embarrassment, at run time. A very important
benefit is shortcutting the turnaround time, if bugs are found at compile time
rather than test time. It seems to me that the aversion to static typing is
because they are not as precise as assertions, which can do any test one likes
to perform, even testing for things as -respondsTo: and conformsTo:. Even that
last one has no equivalent in static typing: id <theProtocol> objects conform
*only* to theProtocol, and understand no other messages, as far as the compiler
is concerned, you have to add a class to that (but should it be Object
<theProtocol> * or NSObject <theProtocol> *, etc.). Furthermore, static typing
does not easily interface with run-time assertions, causing the software to
acquire the brittleness that most Objective-C programmers dislike about C++:
you are invited to statically type *everything, everywhere* and spend the
intellectual effort and time doing that even if you want to test only some
things, and if assumptions change, you might have to do a lot of work to get
the whole system going again (I'm not referring to the fragile-base-class
problem here, which is about assigning slots for instance variables, and, in
C++, virtual methods).
The reason for that is the crude simplifications that occur. For the compiler
to predict, statically, whether certain assertions will be met, data flow
analysis, and in this case, assertion flow analysis as well, are required. But
this is not what compilers do at debugging time, where the desired rapid
turnaround precludes this costly analysis. You really have to simplify things
by doing assertions at the entry and exit points, but by doing that, you might
exclude several scenarios which would not violate the original assertions, and
really give the desired result, just because your entry-and-exit assertions
cannot be rich enough. On the other hand, such assertions might also make the
code easier to understand, so they are not all bad.
Other examples:
- A subclass accepts more specific things than its superclass, and assigns it
to the same instance variable. This is statically known, but how do you tell
the compiler to allow for more methods to be sent other than by total
permissiveness (id), and doing run-time assertions?
- If you give an object to a List, or a Bag, and then take it out again, the
compiler will have forgotten its type (C++ uses templates here).
- The compiler could reverse-analyse assumptions about messages an object
should respond to, to the point where that object enters the code (like a
method argument), and do a check there, or even a run-time assertion.
Currently, the program will fail only when the message is sent, unless the
effort is spent to write a start assertion.
And also, of course, doing compile-time checking (compile time/link time is
more a technical distinction which I don't make here) requires coordination
between all the relevant sources, with parsing and stuff, because there is at
present no predigested format to make this cheap to do. It would be interesting
to see future systems that do this analysis while you're writing that code.
Of course, using id throughout, and assertions to detect problems as soon as
possible, are a very good way of implementing DIRTNT systems (Do It Right The
Next Time), which you can just stop, have cured (no sweat, let's go out for a
break or do something else first), and start up again. But if I want to fly in
a plane that depends very much on computers for its operation, I would prefer a
DIRTFT system (Do It Right The First Time); maybe traders might not appreciate
any downtime either. I realise that this is an elusive concept, but checking
things before run time certainly helps. And I also think it's better to design
other programs that way, following sound engineering principles of quality
control (has a good ring to it, hasn't it?). And, of course, it might improve
productivity by short-cutting the development cycle.
There already are languages that do simple compile-time assertions. It's called
programming by contract.
Just a few thoughts here, which might or might not be valid. I hope they will
cause an interesting discussion, where the authorities can argue their case,
and from which I can learn! It will certainly be interesting to hear David Stes
elaborate before a public of critical experts on what at first sight seems like
a dogmatic statement (just challenging...).

I'm afraid that even that won't work, unless you are unconcerned about
precision. Most EOF discussion takes place on the EOF mailing list,
and in fact this horse has been flogged on that forum-- see the thread
entitled NSNumber precision with Money.
To get to the mailing list:
http://www.omnigroup.com/MailArchive/eof/
In a nutshell: using floats or doubles (or NSNumber formatted for double)
to represent fixed precision
values (like money) leads to apparent weird rounding errors
during operations. This is because
floating point representations of numbers are only guaranteed to
be accurate to a certain precision-- beyond that precision
anything goes. So a literal of 2.40 assigned to a float variable,
can be represented in the float as 2.3999999999999. When the float
value is formatted for output, it is truncated at some arbitrary
point, so that the final string value displayed could appear as
"2.39", if you were to use %.2f for output format.
To avoid this problem you must represent these fixed precision numbers
internally with integers, and perform input and output conversions
yourself. In EOF the proper way to do this is to write a custom class
that conforms to EOCustomValues protocol.
Hope this helps.

Excellent post!
Using static typing (in Objective-C) saves all kinds of time by having the
compiler catch a whole class of common errors (sending messages to objects
that don't understand them). NeXT is right to use typing much more in
OpenStep.
That doesn't mean you shouldn't use id, when you really don't have any idea
what class is involved.
If you prefer finding such errors by linking, testing, hoping to execute the
problem statement under the right conditions, and then poking around in the
debugger - instead of getting a compiler warning right away, go ahead.
But I'd rather save that effort for the more insidious bugs.

Hello all,
I want to prevent the generation of default copy constructors for a bunch
of classes all derived from the same base class. I thought that by putting
a declaration of a private copy constructor in the base class, I would
tell the compiler not to generate copy constructors for any of the derived
classes.
I tried this under GNU C++ 2.5.8. (I know 2.5.8 is old, but I'm depending
on the changes Next made to it to support the NextStep environment and
Next doesn't seem to supply any newer versions of the compiler).
Here's a small example program:
class Base { private: Base(const Base&); public : Base() { } };
class Derived : public Base { public : Derived() { } };
class DDerived : public Derived { public : DDerived() { } };
main() { }
When I try to make this program, the machine says:
> cc tryMe.c
ld: Undefined symbols:
Base::Base(Base const &)
In other words, somewhere in my program there's a call to the private copy
constructor of my base class, presumably in a *generated* copy constructor
in one of the derived classes. As generated copy constructors are public,
this would be a disaster because the real-life classes I'm building may
not have decent copy semantics or I may have defined the copy constructor
for private use by Base's members only.
Does anyone know:
[1] Who's right, GNU C++ or me?
[2] If I'm right, has this bug been fixed in versions of GNU C++ > 2.5.8?
If so, in which version? Does anyone know of a working implementation of
this version supporting NextStep?
[3] Again if I'm right, does anyone know of a workaround?
Thanks!

It is quite acceptable. Again, depends on what you are doing. If ObjTcl
is the glue, the scripting code, the interpreter, but the heavy work
(whatever that means!) is in your objects (ObjC), then it is fantastic.
I have entire apps that are written in 100% ObjTcl, but they are NOT
analytical, just Data Gathering and dissemination, and they are fine
(if they are slower, it is not enough for me to notice or care ...).

The place where I work has a NeXTstation (yes, a real 680x0 NeXTstation --
but not color) running NeXTstep OS. We've found a bug in the scanf()
function in the standard C library, that improperly reads and stores floating
point numbers. The company writes software that's heavily-dependent on this
functionality, and this bug is, to say the least, irritating.
We've consulted with NeXT, and found out that: (a) their tech support,
and perhaps the whole company itself, is a LOT worse than it used to be;
and (b) NeXT wants an insanely huge amount of money to fix this little
bugger.
I had an idea last night, though. It seems that NeXTstep is based havily on
GNU stuff -- the compiler reports "GNU cc version 1.something" as its
version, and (though I have no way of checking) I bet the libraries are based
on GNU libc as well.
Would it be possible to grab the latest source for gcc, g++, and glibc off
the Net, and install them? Would that fix the scanf() problem? Can this be
done? Or, if I do it, will it erase some NeXT-specific customizations,
custom functions, etc. that the system is dependent upon?

Metrosoft has a program called MetroKeys that is a record and playback
tool for NEXTSTEP. Try emailing info@metrosoft.com.
In terms of test tools there is scant little that I have seen. Eastern
Systems in Westboro, MA has a test tool that runs on Windows, but connects
to a Intel machine running NEXTSTEP and captures all of the video events
and is then able to perform as an Automated Test Tool for NEXTSTEP apps.
Their number is 508.366.3223. The product is called Evaluator FT.

When you ask NeXT to have documentation about loadable FS they say all you need is in some .h in /headers directory and in already given executable in /usr/filesystems/* (MAC, DOS, CD... just use Edit to view them or try to run them manually from a shell).
Request for info about loadable fs is not new. NeXT's answer about this not too.
Good luck.

I think static typing is the wrong solution to these problems. One of the
great things about Objective-C is that as long as your object responds to
the right messages other objects don't care about what that object is.
Now NeXT is trying to force us to pass specific objects around. Which
means that if I want to pass in a NSViewString (a subclass of view that
implements the NSString methods) to a method that takes a NSString, I'm
going to be stuck with a warning, or type casting the NSViewString to a
NSString, which defeats the whole purpose of static typing (since instead
of type casting a NSViewString I might have accidentally typed cast
some other object).
This brings me to what I think would be a slightly better solution, why
not use protocols to avoid sending messages to objects that don't respond
to them. Basically instead of having
- aMethod:(String *)aString
lets have
- aMethod:(@protocol(NSStringExtensionMethods))aString
this would provide as much compile time error catching as static typing
with the advantage that aString could be any object.
Comments?

That should solve your linker problem (the copy constructor
was not defined in your example). There is nothing wrong
with what you are doing (I tested this example with Gnu 2.xx?
and with Microsoft C++ (Visual C++ 2.0)).

Hi everyone,
I am looking at writing a device driver for a touch screen - either ISA

pointing device drivers, but there are headers for event protocols.
Can someone point me in the right direction for some help, source of a
similar driver (e.g. Talus's Waccom driver) would be wonderful.

My favorite highlights in addition to OPENSTEP on Windows NT, D'OLE,
WebObjects, etc, etc, are the following:
1. Flat Panel display with HPPA RISC workstation inside
2. Tadpole laptop with 135MHz Pentium, color 800x600 with screen panning
3. Lighthouse Design announced ObjectPlan case tool
4. Teknekron's ObjectBus -- True broadcast, publish & subscribe and
guaranteed delivery
5. Objective-TCL
6. A SPARC laptop running NEXTSTEP in color at 1024x768, first laptop to
do this. Unfortunately I did not get to see this one. Anyone saw it?
7. Miscellaneous: EOF 2.0, PDO 4.0, etc.
__________________
* A PixelVision 3-inch deep flat panel display with an HPPA RISC computer
inside. I did not realize this until I asked, okay this looks really
nice, but where is the computer? It turned out that it was inside the
monitor. It had a 1.? GB hard disk, 64MB of memory, etc, etc. You could
even connect a second flat panel display. It was a multiheaded system.
And best of all, it was running NEXTSTEP and it supports the multiheaded
graphics subsystem.
* They also had a Tadpole laptop with a 135MHz Pentium running NEXTSTEP in
color at 800x600 but with a true screen resolution of 1024x768 with screen
panning. You move the mouse beyond the edge of the screen and it scrolls
using hardware screen panning. You can connect an external display to
view the whole 1024x768 without having to reboot. Really nice!
They also had an NEC flat panel LCD color display running 16-bit color at
1280x1024.
* Lighthouse Design announced ObjectPlan but it won't be available soon.
This tool complements their awesome Diagram product and it is basically a
CASE tool for design and analysis that works with Objective-C and C++ and
it has hooks so that you can use it with other languages. It can also be
used to reverse-engineer foreign source code libraries and they have plans
to integrate it with NeXT's Project Builder and SUNSOFT's DOE environment.
* Teknekron Software Systems at the Sun booth was demoing a CORBA 2.0
compliant product running on NEXTSTEP/SPARC. The product runs also on
Windows NT, plain Windows, UNIX and VAX/VMS operating systems. The demo
consisted an implementation of the application that comes with NEXTSTEP
that demonstrates distributed objects. You drag a dot in a window and all
the other instances of the app update the same dot to the new location.
This app used point-to-point messaging. Then for the demo, Teknekron
implemented the same app using their ObjectBus product which was using a
true broadcast from what I was told. He had two workstations and you
could tell the difference. He said that this was scalable to a large
number of workstations, e.g. 1000 workstations. It also supports publish
and subscribe. In addition to all this, he said that it had guaranteed
delivery for transaction support. For example, if the process where the
targe object was not running when a message was sent with guaranteed
delivery, then the object would eventually get the message later when the
process it lives on was launched. This product is CORBA 2.0 compliant.
* Objective-TCL was being demoed and I liked it. They had a palette and
the most impressive one is the one that allows you to enter code and
execute it without having to recompile. They executed code in Interface
Builder without recompiling. It has Objective-C-like syntax, but for
declaring a class, they use a slightly different syntax. Also, variables
are typeless. Overall, it looked really nice.
* BlackSmith announced DataSmith. The description hints that it will have
a feature I've been wanting for a while, which is being able to load
custom written EO's to pull data from them. For example, we should be
able to ask a CustomerOrder object for the total instead of having to
write a script that computes it as in other report tools.
Also it seems like NEXTSTEP 4.0 will have shared library support, PPP
bundled and improvements in the GUI. Too bad they did not demo it, I
really wanted to see it.
Also, it seems like EOF 2.0 will have some nice improvements regarding the
saving of EO's and some of the subtle problems in the EOController to UI
layer. From what I understood, you won't need the EOController in order
to save your EO's, making it nicer for those developing PDO applications
where you can't use EOController objects.
OPENSTEP for Windows NT and Windows 95 will have the Windows look and
feel. This should look really nice with the Windows 95 GUI. The Windows
NT look is "ugly" but Windows NT will be getting the Windows 95 look soon.
Steve Jobs said that they were optimizing it for the Windows 95 GUI since
the current look is going away.
PDO 4.0 will incorporate CORBA. I'm suspecting they will be using the
Dynamic Invocation Interface (DII) part of CORBA which is similar to OLE
Automation which is what they used to integrate OLE with Objective-C.
Visual BASIC and the Visual-BASIC-like language in most Microsoft apps
such as Excel have the ability to do OLE Automation which means, being
able to message an OLE/COM object. Given, Objective-C's ability to go
from a string containing a method name to a selector used to message an
Objective-C object, this should be no problem for Objective-C. Do this in
C++.... I guess that's why Visual BASIC is still so popular for OLE
objects.

Ricardo

Declare a private copy constructor in each of the derived classes?
Find where the copy constructor is getting called and fix it. After
all, without the compiler bug, your program wouldn't have compiled.
(As a start, try using nm to find which module has the undefined.)

Has anyone else found a problem with (16-bit or larger) sound files

I assume the problem is that 16-bit integers are different on these two
machines...big vs small endedness...
There doesn't seem to be any direct way a program can tell which form a
sound is...so that I somehow seem to need to remember where I generated
the sound...before I try to play or process it.
Any solutions?

I would love to have the response to, as I hitted it a week ago (and I

Due to what I was trying, it smell like a kind of 're-entrancy' problem,
but I didn't had time to track it down enough.

Hi,
I'm writting a network driver derived from the class IODirectDevice. I need
to implement the outputPacket method from the protocol
IONetworkDeviceMethods. My question is:
Does the parameter represent the IP address ? I think it is but I'm not
sure. Could somebody say me if I'm right or not ?
Thank you for your help.

In the NXReference protocol documentation (Dev 3.3), it is stated that:
=========== quote begin
A typical implementation for a reference counted object that is vended
over a Distributed Objects connection might look like this:
- free
{
refs--;
if (refs > 0) return self;
[NXConnection removeObject:self];
return [super free];
}
=========== quote end
I'm not a DO expert, but if the client performs a free on an object vended
by some server, its proxy is freed and the method above is called. Buf if
the refs counter does not reach zero, the function above returns the
server object again to the client which creates a new proxy on the client
and thus cause the method addReference to be called on the server.
The client then thinks that it is not connected to the server any more and
will not call a free again on this object. This cause the server refs
counter to never reach zero. Returning nil instead of self in this case
should fix this problem.
Any opinion on this subject ?
Nicolas.

I disagree.
Original problem is not in the linker error, and your advice will not solve
it. Compiler for some reason (due to a bug, I think) requires copy-ctor for
given example, so your advise will lead to a compile-time error instead of
linker error.
IMHO, private copy-ctor in base cannot help in given problem,
at least not in all cases. It only can indicate, that some code calls it -
usually, with a compile-time error.

Except for this:
When you static type parameters, you blow away some of the concepts of
ploymorphism. Yes, I understand protocols, and yes, they're a big hack.
The problem is this:
You write all kinds of code to use a particular object. Say
NSMutableGarbage. Once you decide that NSMutableGarbage isn't the class
for you, and you write your own MyMutableGem class to replace it, you're
looking at changing a million declarations and associated methods which
also static type their parameters. Do this a couple times, and you have
a hellish mess on your hands.
Yes, you can save some pain by static typing to protocols, but you can
get similar problems, *and* most people aren't going to do that anyway.
I wish that people would just stop rushing to one side or the other of
the boat, because the NEXTSTEP programming boat is continually listing
to one side or another.
Static types are a tool. They are noting more than that. Use them
judiciously, but not to the exclusion of the id type. The id type can
make for an elegant clean chunk of code which is easily maintainable.
Static types can give more bulletproof explicit code, but can be a pain
in the ass to change.
>That doesn't mean you shouldn't use id, when you really don't have any idea

Or, when you want your code to be dynamic, as well as the program.

The amount of time we spend trying to track down respondsTo: errors is
negligable in the larger scale of things.
Also, this:
- takeThis:this andThis:somethingElse andMakeThis:product;
Looks oh so cleaner than:
- (NSMutableGarbage *)takeThis:(NSGarbage *)this
andThis:(NSMutableGarbage *) somethingElse
andMakeThis:(NSMutableGarbage *)product;
Is it more expressive or less expressive? I dunno... too much noise for
me sometimes. The oter thing that ticks me off is the reverse C was of
looking at const and mutable. I wish the default way was this:
NSConstGarbage
NSGarbage
Rather than:
NSMutableGarbage
NSGarbage
It's reverse to the way you think using the standard C types. I'm sure
they have an argument that it makes more sense in a class heirarchy way
(and I think I've been told it) but that doesn't stop it from being ugly
and inelegant. Anyway, it doesn't matter all that much to me since I'm
doing most of my stuff in ANSI C anyway ;-).

True, but I'd say the warning is appropriate in this case. The method may
send any NSString message to your object. There's no guarantee that you
implemented each and every one of those methods in your subclass. If you
pass in a kind of NSString, you're guaranteed to respond to those messages.
The warning reminds you of that potential danger. Your caste informs the
compiler and future maintainers that you have taken care of the situation.

This is a better solution in many cases, and the language already supports
it. But the syntax is:
- aMethod:(id <NSStringExtensionMethods>)aString

By how much did it increase? If by about 10 bytes, then I would guess
(depending on the compiler options you used), that it is embedding your
compile command line in the binary, and that the binary's size increased
because the length of the compile line string increased. By the way, trying
this on an Intel machine resulted in no increase in binary size for me.
BTW, this should not, by itself, result in the formation of a fat file, as
another respondant suggests.

Seriously, I am *not* sure what you are asking (or implying?). I think
that you either had a typo or a grammatic error? Anyway, I will answer
as *if* you were asking a question as to whether ObjTcl supports
autorelease, etc. (hope that was what you were getting at :-)):
ObjTcl is fully FoundationKit compliant (and aware). As such, there are
a number of convenience procs for handling NSStrings, NSDictionaries,
and NSArrays. Of course, having seen this simple yet extremely useful
procs, one realizes just how easy it is to extend that to anything else
(Foundation or otherwise).
Anyway, there *are* autorelease semantics built in (via procs) to ObjTcl.
As one example, in certain circumstances, you will use rrset rather than
set (rrset = retain/release set!). Hope this helps ... (someone, if not
you Robert :-)).

James Kanze responded that you are right, but I think GNU C++ is. You
declared, but did not define a private ctor, Base(const Base&), so a
linker error referring to the _private_ one is to be expected. Using
your example on gcc-2.5.8 on an hppa, I get your same error. But if I
make the change,
< class Base { private: Base(const Base&); public : Base() { } };
---
> class Base { private: Base(const Base&) { } public : Base() { } };
it compiles and links without error.
On the other hand, if after making the above correction, I go on to
test the copy inhibiting mechanism by,
main()
{
Base b;
Derived d;
DDerived dd;
Base cb = b;
Derived cd = d;
DDerived cdd = dd;
}
I find that gcc-2.5.8 gives an error message for the `Base cb' line,
as it should but not for the next two lines. In fact, if the `Base
cb' line is commented out, the program will compile and link although
it should be ill-formed according the the C++ draft standard of April
95 which says,
Section 12.8
7 An implicitly-declared copy constructor is implicitly defined if it is
used to copy an object of its class type, even if the implementation
elided its use (_class.temporary_). A program is ill-formed if the
class for which a copy constructor is implicitly defined has:
--a nonstatic data member of class type (or array thereof) with an
inaccessible or ambiguous copy constructor, or
--a base class with an inaccessible or ambiguous copy constructor.
So it looks like gcc-2.5.8 is wrong in a more extended example.
|> [2] If I'm right, has this bug been fixed in versions of GNU C++ > 2.5.8?

With gcc-2.6.0 or later (on a Sparc) I get the following error
messages for the `Derived cd' and `DDerived cdd' lines:
pctor.cc: In function `int main()':
pctor.cc:13: too many arguments for constructor `Derived::Derived()'
pctor.cc:14: too many arguments for constructor `DDerived::DDerived()'
which is a rather confusing message in our context, but not an
unreasonable one. Apparently the compiler has been inhibited from
defining a copy ctor is complaining that the only ctor it has does not
have the right arguments.

That would be my conclusion as well. Thanks for taking a look at that.

Well, yes. But - at least in my code - it is _extremely_ improbable
I'll write a source which suppose it will use (any subclass of)
SomeFunnyClass, deciding later it will cooperate with some other,
unrelated class. Surely there _are_ programs I am not sure I won't
do such a switch in future; but then I use id instead of static
typing.
And - IMHO, of course - the annoyance of (most improbable) changing
of SomeFunnyClass* to OtherFunnyClass* in whole project (in fact,
using awk even this is _very_ easy) is absolutely unimportant
compared with static typing benefits (ie more compile time
checking).

Surely - in my personal opinion, the NeXT's decision to use the
longest possible names was not particularly smart :(((
On the other hand, we might to help us using better indentation:
-(NSMutableGarbage*)takeThis:(NSGarbage*)this
andThis:(NSMutableGarbage*)somethingElse
andMakeThis:(NSMutableGarbage*)product;
seems to me only _slightly_ less readable as the original untyped stuff.

Well, you have to find the smaller evil... It would not be
particularly consistent to have a inheritance tree of
@interface Xxxx:YyyyXxxx
which is exactly you would get:
@interface NSString:NSMutableString
It is a good practice to use class names the way of 'adding text
and functionality as well' - ie, if you have two class named Xxxx
and YyyyXxxx, then the latter isKindOf: the former, adding the Yyyy
feature.
IMHO the decision to omit the plain C consistency for the sake of
object consistency was good.

It has to be boring to implement your own NSArrays, NSDictionaries,

Subject: compositing large nximages
Date: 20 Aug 1995 14:43:54 GMT
Organization: (null pointer)
Message-ID: <417hna$875@nic.wat.hookup.net>
When compositing a large nximage into a view during a drawself, I get a very
small version of what should be a 1024x1024 image. The window shows
up at the proper size, but the image is a very small one down in the
lower left corner. I don't get this anomaly for smaller iamges.
Here is the drawself:
- drawSelf:(const NXRect *) rects :(int) rectCount
{
NXPoint point = { 0.0, 0.0 };
[image composite:NX_SOVER toPoint:&point];
[self drawRegionSelection];
return self;
}
If I switch the composite: message for a drawIn: message, then the
image shows up as it's proper size. However, later on I composite
region selection cursors onto the view and erase them by compositing
little bits of the original image. So it would be useful to get
the compositing to work.
Here is how the image is built from a TIFF:
- loadTIFFImage:(const char *) filename
{
id newImage;
char *filenamePtr;
NXSize size;
// allocate a bitmap image rep,
// and have it read in the TIFF image
imageRep = [NXBitmapImageRep alloc];
// initfromfile will free the bitmapimagerep
// if it can't find the file
if( [imageRep initFromFile:filename] != nil ) {
size.width = [imageRep pixelsWide];
size.height = [imageRep pixelsHigh];
[imageRep setSize:&size];
newImage = [[NXImage alloc] init];
[newImage setDataRetained:YES];
[newImage useRepresentation:imageRep];
// setup window for new image and save
// image internal to this object
[self setImage:newImage];
// save file name
strcpy( imageFilename, filename );
// set window title to file name
filenamePtr = rindex( imageFilename, '/' ) + 1;
[[self window] setTitle:filenamePtr];
return newImage;
}
else
return nil;
}
Any assistance on this problem would be greatly appreciated!!!
Regards,
Jim.

Shouldn't be: the sound should be big-endian in either case.
If you're creating sounds on Intel, you should use the NXSwapHostToSound()
(or somesuch) function before you use the data.

If the thing is swapped throughout, the magic number should be swapped too:
there's a NS constant defined appropriately to check.

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

[from the document ftp://ftp.next.com/pub/NeXTanswers/1000_Help]
Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.
USING NEXTANSWERS BY FAX
To use NeXTanswers by fax, call (415) 780-3990 from a touch-tone phone and
follow the instructions. You'll be asked for your fax number, a number to
identify your fax (like your phone extension or office number), and the ID
numbers of the files you want. You can also request a list of available
files. When you finish entering the file numbers, end the call and the
files will be faxed to you.
If you have problems using this fax system, please call Technical Support
at 1-800-848-6398. You cannot use the fax system outside the U.S & Canada.

Only if the function is used. It is not an error to not provide a
function that is not used.
So: who is using the copy constructor? If it is not being used, then
there should be no linker error. If it is being used, there should be
a compiler error (unless the use is inside a member function).
(Formally: the linker error message can be considered a diagnostic in
the sense of the standard, so the compiler can be considered
conforming. However, it is certainly not the ``diagnostic'' one would
expect, and I think that the people at Cygnus would, in fact, consider
this an error.)

From the 3.1 Release notes for Sound:
New Features
Š Two new ƒsound-porting functions have been added to the sound
library and declared in <sound/utilsound.h>:
SNDSwapSoundToHost(void *dest, void *src, int sampleCount,
int channelCount, int dataFormat)
SNDSwapHostToSound(void *dest, void *src, int sampleCount,
int channelCount, int dataFormat)
These functions read the data pointed to by src, swap the order of the
bytes that comprise each sample (if necessary) and write the swapped data
to dest (src and dest can be the same pointer). The other arguments
describe the sound data buffer; cumulatively, they tell a function how many
samples are in the buffer, and the size of each sample. The functions
return error codes that report their success or failure.
The ƒSound and ƒHost terms in these names have these meanings:
Š To play a sound, the sound data must be in ƒSound format.
Š To examine sound data, it must be in ƒHost format.
When you read a soundfile or record a sound, the sound data is guaranteed
to be in ƒSound format; if all you want to do is play the soundfile or
write the recorded sound to a file˜in other words, if you don't want to
examine the data˜then you don't need to call these functions.
However, if, for example, you read a soundfile in order to look at the
value at each sample, you must first call SNDSwapSoundToHost() to convert
the sound data to ƒHost format. If you modify samples in a converted
sound, you must re-convert to ƒSound format, through SNDSwapHostToSound(),
before the sound can be played or written to a file.
Note that you don't have to convert entire soundfiles (or SNDSoundStruct
data buffers) at a time.
These functions are built upon the general NXSwap... functions that are
described in /NextLibrary/Documentation/NextDev/Concepts/PortabilityGuide.
The primary difference between the sound swapping functions and the general
swapping functions is that the sound functions let you convert buffers of
data, whereas a single call to a general function can convert only one
datum. If you wish, you can call the general functions (iteratively)
rather than the sound functions. The correspondences between the
functions are:
Sound function Analogous general function
SNDSwapSoundToHost() NXSwapBigShortToHost()
SNDSwapHostToSound() NXSwapHostShortToBig()

Sound is always big-ended as a file, the swap routines will get it into a
format suitable for processing in the program but it is written out again
as big-endian. I just finished porting the sndutil routines to Intel
available from CCRMA, where Julius Smith (Gosh, that's three different
Smith's all in computer music... :-) is giving them a going over before
inflicting them on the rest of the world. They are short examples of the
approach if you wait for them to appear, or for the foolhardy, I can email
some code.

According to NeXT, NEXTSTEP/HP uses the same calling conventions as HP/UX,
as documented in the "PA_RISC Calling Conventions Reference Manual".
According to me, NeXT has (or had) some bugs in their stack layout with
regard to character and short arguments. NeXT's marg_ functions also
return improperly aligned values for double arguments which'll cause fatal
program errors (unless you manually rewrite the marg_ functions yourself).
Consult Bug_NeXT reference #60250.
-Chuck
PS: The stack on the PA_RISC systems does grow upwards, unlike the m68k or
i386 architectures, although the argument list within a given stack frame
grows downwards.

If you look at a NeXTmail message, it's pretty straightforward.
Take a message, uudecode it
uncompress it
untar it (using gnutar)
(well, actually, using safetar inside of
Mail.app, but I don't know if you'll be
on a NeXTSTEP box when generating these
files...).
You'll get a directory of files. Note that the key file is an RTF
file, so you'ld need to know how to generate an RTF file which
points to all the other files you want to include. Take a look
at some NeXTmail files sent to you to see how this works (which
is to say, "Don't take my word for it..." :-) ).
It's doable. Some of my friends wrote scripts of some sort
to send NeXTmail to me. I'm not sure if they still have
those scripts around. It's reasonably straightforward.

It depends: if you are using .snd or .aiff or .wav files, it is defined
wether the data is big or little endian, and any Player (like Resound.app)
knows how to handle it properly.
If you have raw PCM 16-bit data, you can use sox or sndconvert to make a
sound file with the appropiate header.

Look closely:
- every one of those three functions is included in /usr/shlib/libsys_s.B.shlib
(with the leading underscore, e.g., _NXIsDigit),
- NXIsDigit is *also* present in /usr/shlib/libNeXT_s.C.shlib as
__libNeXT_NXIsDigit.
The first item is normal: all those functions are defined for every program
that links with the implicit library sys_s (I won't speak for posix stuff). The
second probably merely means that the function is *referenced* by some code in
the NeXT_s shlib (a shlib wizard will be able to tell you what's happening
exactly); you'll still want the sys_s library to link with.
This is for my NEXTSTEP_3.2 system. I haven't really checked the .a libraries,
but I suppose they match their shlib counterparts.
Conclusion: Not a bug.

On a local (bay area) TV station last night during their occasional focus on

that OpenStep was highly regarded at this year's ObjectWorld, and they showed
an excerpt of Steve Jobs talking about it. (Looked like it might've been
from a panel session or something rather than a keynote.) I wish I could
tell more details but I was actually in another room when shouts of "Come

this so they can report further?

I believe it is just a "Services" definition with the following--

I'm beginning to think that the new Foundation memory management
scheme is just trading one problem (object ownership) with another
(avoiding cylic retain references) with little net gain. Or maybe I just
don't get it :-)
I seem to be spending an inordinate amount of time trying to figure
out how to break cyclic references. In general, I've followed NeXT's
example of retaining objects passed into "setIvarName:" methods as
arguments to prevent them from being released while still needed.
A simple, obvious example is a delegate which, according to NeXT's
docs, is documented as retained in most cases (but not EOController!).
What does one assume when no mention is made of whether an object is
retained in a "setIvarName:" method? Frequently, the delegate refers back
to the object whose delegate it is by storing it in an ivar. This
"setIvarName:" method obviously can't retain its argument or a retain
cycle will result preventing either object from ever being released.
But what I'm experiencing are retain cycles that include 3 or more
objects. These can be difficult to detect and prevent :-(
What I'm looking for are general guidelines about which ivar shouldn't
be retained in order to prevent cyclic references. I've heard a
distinction made between intrinsic and extrinsic objects, but this seems
like a gray area to me in many cases. Anyone have any clever approach
that they'd like to share? This is really bugging me.

ethernet card (3C509B-TP), but neglected to enter Configure.app for the

fine (or so I thought) and then I restarted and got the following

Waiting for RDP connection (type 'c' to continue)
at which point, nothing can save the bootup (hitting 'c' gets the same
last three lines).
What I need ideally is a way to get the NeXT to boot so I can
deinstall the uShare and the EtherLink III driver and try it all over
again (correctly this time). Can I start up NeXT with "extensions off"
as with a Mac? Otherwise, I assume that I'll need to reinstall NeXT ...
can I install NeXT without losing other data files on the disk?

Message-ID: <paulrs-2208951125210001@lgs-systems.buf.servtech.com>
Hello,
I am creating an addresses database in which I would like to allow the
user the ability to drag and drops links into a comments text area. I am
aware that the text area needs to accept graphics in order for the user to
be able to drag and drop items into the field. I've created my address
book and the scrollable text area for comments and the user can drag and
drop links without difficulty into the comments field. Further, the links
are saved to the database and can be retrieved without a problem.
However, when the user double-clicks on the icon for the link nothing
happens. If I try the same thing in say an 'Edit' document, the link, if
it's a directory, will open up a window in the Workspace Manager when
double-clicked. I want the same sort of behaviour in my database.
Thinking that my problem might be app specific, I created a dummy
project with one window and a scrollable text area. When I compiled and
ran this app, I experienced the exact same behaviour as in my database.
My question then is, do I need to subclass Text in order for this to
work? Or is there some delegate method which I need to handle? Or can I
override some method in a category? Any help would be greatly
appreciated.
Thanks,
Paul

The person who comes in after you, be they a programmer, consultant, or
whomever, might have different ideas. Or, you might "switch kits" or
NeXT might drop a kit and replace it with something else. All of these
happen all the time.

When you've got a 1 million line project, upon which people's *lives*
depend (this is really mission critical stuff), are you going to run awk
over the source code? I think not.

I didn't say you did. The policy of NeXT, however, now looks to be
"never use id" and that's really what I'm attacking.

Well, official emacs indentation is:
-(NSMutableGarbage*)takeThis:(NSGarbage*)this
andThis:(NSMutableGarbage*)somethingElse
andMakeThis:(NSMutableGarbage*)product;
And is an improvement again, but it's still god awfully ugly and
inelegant. Of course, as you've pointed out, the long names coming out
of NeXT these days make some things absolutely ridiculous.

Oh great. So, you're telling me that if I have five parent's in my class
tree, then I should incorporate text from each of them. That's
brain-dead. There's nothing that says that class names should abide by
any set of rules. Moreover, this is one of those cases in which
following the rules which commonly give you good results, gives you bad.
Yes, it makes plenty of academic sense, but from a practical point of
view it's a stupid decision.
const int <- a constant number
int <- a mutable number
NSNumber <- a constant number
NSMutableInteger <- a mutable number
Stupid, stupid, stupid.

Well, you're wrong ;-). ObjC is a superset of C. They destroyed the
consistency of the *ObjC* language for the sake of following a couple
silly rules that don't really make much sense. You can argue that a
class tree using "const" can be made just as "elegantly" as one using
Mutable. So what if you don't inherit their names? Big bloody deal.

Quite to the contrary. When my data structures outperform NeXT's by
factors of 5, while taking up less space, and are portable to 5
operating systems and provide the core functionality for object wrappers
in three OO languages, I get *excited*. You want code reuse? *That* is
code reuse. My stuff blows away NeXT's even after you put the ObjC
wrapper around it. That's fun, and cool. And, you know it's going to
work fine in other languages too.
Check it out... these are standard array data structures. They all have
the same interface in ObjC:

Message-ID: <41d8eh$ib7@medusa.is.com>
Hi,
I need to send an Objective-C from a C environment. Target, selector,
arguments and there types as well as the return argument are known during
runtime.
I tried building a marg_list from the arguments, and used objc_msgSendv,
and that kind of works, if the return value has a size of four bytes.
Here are my problems/questions:
How do I get to a return value, that has a different size than four bytes,
eg a double (8 bytes)?
The brute force attempt does not work:
double d;
d=(double)objc_msgSendv(...
results in a compiler error.
This is also not exactly what I need, I would more need something that
would work for any number of returned bytes.
The second question:
I would rather like use objc_msgSend than objc_msgSendv, especially since
there is no objc_msgSendSuperv...
Is it possible to do something like
pushInt(i);
pushDouble(d);
erg=objc_msgSend(theReceiver,theSelector);
Of course I need to stay portable, so please no assembler code...
I hope somebody can help.
Please answer via EMail, our newsfeed is usually 24 hours late. I will
summarize.

Agreed. These timings are impressive and important gains as well.
For Foundation stuff now, and for 4.0 (OpenStep) in general, do you
just cast these to NSArray (etc.) to remove the warnings, and do you
convert what you get from AppKit back to *your* cannonical classes (
for example, if you had an NKString, when a TextField gave you back an
NSString, would you convert it)?
Also, and please no one flame me (really!), if they are truly plug and
play alternatives (protocol-wise) to NeXT's, and are so much faster,
did you "offer" the code back to NeXT so that we could all gain?

Maybe it's due to the images resolution! If the image is e.g. 300 DPI it
will show up on screen in about a quater the size that pixelsWide/pixelsHigh

But unfortunately I have no idea of how you could change the images

Hullo,
is it possible somehow to obtain the current keyboard state? I'd
need to know at least the current state of the Shift, Alternate,
Control and Command keys (it will be nice to be able to test other
keys as well, but the ability to test the modifiers is much more
important). I need to get the state in regular intervals, regardless
the application state (fore- or background), so I cannot use the
modifier state recorded in the event.
I had found the PSbuttondown etc. services which do this for the
mouse, but I had found nothing for the keyboard. Can somebody help

Here is a short example that does this. (all of the code assumes that

self is a subclass of list.

Hope this all helps.

aSelector = [self getSelectorForIdentifer:(const char*)identifier];

I got this freed id problem, which drive me crazy. In NeXT ObjC runtime,
objc_msgSend, I guess, detects the receiver of a message is freed, so it
calls _freedHandler, which ends up calling abort(). In BSD 4.3, abort()
sends signal 6, which cannot be caught or blocked. So even if I had
ObjectError in place, I still cannot get a back trace. The message sent to
the freed ID is respondsTo:, which I only used once surrounded by my own
freed id check. So the message is likely from code in Appkit. The problem
is a headache since I cannot reproduce it when running under GDB, but occurs
again and again running on user machines with no development tools.
Is there any better way to handle the freed object, such as an undocumented
call to set your own freed handler, or to force it to call [Object error:...]
instead of abort().
Many thanks.

Does anyone know how to get the NXPrinter to recognize the PPD keywords
JCLResolution and JCLEconoMode? I've been messing around with a couple of
PPD files and can't get PrintInfo to recognize tons of PageSizes. It's
almost as if the popup list for Page Layout only has a small set of
options. Unfortunately, none of those option include envelopes!
The problem also bubles to NXPrint, where the keyword *JCLResolution does
not effect the Resolution popup, but *Resolution does. I guess I'll have
to dig in more on the PPD spec to figure out how to have both in the file,
the *Resolution just calling the *JCLResolution.
As far as I can tell in the PPD spec, constraints can be made within the
PPD file to handle all sorts of options. Like only allowing the paper size
for an envelope to feed from a tray that can handle envelopes - to making a
definition for Transparencies that enforces the output bin.
Lots of options!

I've used setTitleFont: and setFont: to change the font in a DBTableVector

row, the table view uses the height of the "old" font (normally 12pt) to
do the highlighting. I must need to set the "row height" somewhere, but
can't figure out how. (You would think the table would be smart enough
to detect this itself!) I noted that the Inspector for DBTableView in IB has
a Row Height field; if I trace thru the assembler in gdb I see that it is
sending setMinSize: to some table vector, but I can't figure out which
vector; it must be the global one for all dynamic rows in the table. The
Inspector used the method "uniVector" to find this puppy, but I lost the
scent at that point. Can anybody help me figure this one out? Thanks...

(giving the MutableString / String example)
Don't do this. Rather, declare a string object, and the mutability (?) of
the string as some sort of attribute :
@interface String : Object {}
- setMutable:(BOOL)flag;
- (BOOL)isMutable;
@end
A good example is Window (retained/non-retained/buffered), you don't have
an NSRetainedWindow etc. ! If you try to "catch" the attributes of the
class at compile time, you'll end up with a large number of classes, and
the application programmer has to read all the documentation to find what
object is suited for him. Bad design like this will also make you think
that the language is lacking features (protocols, multiple inheritance
etc.), while it's a design problem in reality.
You have to try to deliver as few classes to the application programmer as
possible. An object kit is not "more" object-oriented if you have "more"
classes (with a lot of nonsense classes).
Taking time to design a small, clean and concise API really pays off.
And if you think NSRetainedWindow is a good idea, keep it internal, make
Window the only public interface. And _please_ don't use "class
clusters", but rather simply use an instance variable that points to the
internal object.

Yes, there is. Here is some sample code (I hope this isn't too long to post).
Some of the comments are stale, and this code depends on some other additions
to Object, but you can figure that out. The key is that the method
message:sentToFreed:inClass: prints out the name of the method and the class
of the object it was sent to, which 90% of the time is enough to figure it
out. Note also that this code can be circumvented if a subsequent alloc
reuses the storage; in this case, comment out the object_dispose (and watch
your vm skyrocket) to locate the problem.
Normally I leave this code disabled, and only turn it on if I have FREED
problem. I can't WAIT to run via OpenStep so I can use Purify...

NeXTites,
I created all of the Help files for one of our application we
sell at Lynn-Arthur Associates, and when a user searches on a word the
system bombs if the word is not found and say there are three instances
the word in the current doc, it finds all three but if you Find again it
kills the whole application, not just help. Is this a know bug or am I
doing something wrong? I have created the index and I have markers on
almost every page....any help would be appreciated.

This is normal. You call objc_msgSend wich in turn call an implementation
that returns a double. You take the return value AS IF IT WAS AN ID (type
of objc_msgSend) and you try to cast an id to a double.

Much simplier, (but less generic ?) : look at the definition of
objc_msgSend...
objc_msgSend(theReceiver,theSelector,i,d)
/* i and d HAVE TO BE CORRECTLY DECLARED ! */
The return of a double, now. You have to understand that the return of a
type is a 'hard-coded' by the way the compiler generates the code.
To return a non-id type, the declaration have to be non-id.
But, you'll say objc_msgSend is declared id, and the compiler uses it for
non-ids ? How possible ?
Easy answer: The compiler cheat.
Explanation of steps for calling a method:
The compiler pushes the arguments, as for the calling of a function
defined like your method. (But with two more arguments. In fact it is for
calling the implementation (IMP) of the method)
Instead of calling your method, the compiler call objc_msgSend (which is
not declared as returning the good type, but it does not matter, as you'll
see)
objc_msgSend, finds the implementation, based on the class of your object,
restore everything and JUMPS to the implementation.
When the implementation if finished, the return values are passed via
whatever convention is ok for the return type.
You see that in fact the caller and the receiver have agreed on the way to
pass arguments, and objc_msgSend was called transparently.
So you need to do the same thing. (It is called a hack)
Last, the example:
#import <objc/objc.h>
#import <objc/objc-runtime.h>
#import <objc/Object.h>
@interface Foo:Object
{
}
- (double)test:(int)a :(double)b;
@end
@implementation Foo
- (double)test:(int)a :(double)b
{ printf( "TEST\n" );
return b*a;
}
@end
/* This is the type Function to a dispatcher that would return a
double
Any call made via such type force the compiler to use the
convention
used for returning doubles */
typedef double (*double_objc_sgSendType)(id,SEL,...);
/* Cheat: Oh, Mr compiler, the address of that function is exacly
the std dispatcher (which in fact returns nothing as it jumps
to the implementation...which returns double)
*/
double_objc_sgSendType double_objc_sgSend =
(double_objc_sgSendType)objc_msgSend;
main()
{ id f = [[Foo alloc] init];
double d;
/* Ready, set, gooo */
d = (*double_objc_sgSend)(f,@selector(test::),2,(double)3.14151 );
/* ^ This is vital
*/
printf( "%g\n", d );
return 0;
}

Hey,
I write a library for matrices and vectors. During test phase (at runtime) I
need to check if every index is correct and so on. During calculation phase
these checks are superfluos because the cost time. The most common strategie is
to use define statements. OK, then I have to hold two different libraries. But
what If I want the user of the library to take the decision which check to do?
Now I want to expand the concept to message handling (controll output during
runtime). In C++ a idea is to use error/message template classes (which could
adapted to Objective C).
My question: does Objective C support another (more natural/flexible/efficent)
strategie?
Thanx

Hutchison Avenue Software Corp. has enhanced ObjectError to include
trapping messages to freed objects. Their enhancement was (is?) freely
available. The class name is HKCrashTrap which is included in a demo app
named CrashTrap. Not sure whether it's available on NeXT archive sites,
but it's worth looking.

Hi all,
after adding some -posix here and there in the makefiles, I managed to
get freeWAIS-sf-1.1 to what seems up and running on NextStep 3.3.
Unfortunately it does not have an html type. freeWAIS-0.3 has that, but
I did not get that one to compile correctly :-(
I tried to incorporate the relevant parts of freeWAIS-0.3 into
freeWAIS-sf-1.1, which did at least compile, and after reindexing with
-t html I get document types of "html", but the headlines still show
the filename instead of the title!
So, what I would like to know is:
- what freeWAIS compiles on NS 3.3 and has an html type?
(or what do I have to do to get it compiling?)
- how do I pose queries that give me the title as well as the filename
of the .html files found?
Maybe I just gave the wrong arguments to waisindex and waisq, so please
anyone tell me what to do there.
This is really urgent, so any help is highly appreciated.
Thank you, Joerg.
P.S.
if there are any examples on how to incorporate results of wais queries into
html code with a perl script or something like that, please let me know.

Hi,
I can't quite seem to get continuous messages from a matrix in the form I desire. Here is
the behavior I am trying to get:
- On the first mouse down, an action should be sent.
- As the mouse is dragged and subsequently enters another
cell, the action should be sent (basically on a mouse entered.)
I have a matrix of cells which correspond to a visual slider. The visual slider is a visual
representation of the cells of the matrix. As the mouse is moved around from cell to cell in the
matrix, A pointer in the slider while slide back and forth to corespond to the current cell the
mouse is over. Currently, I can only get the action to be properly sent on the mouse up of the
matrix. Any twiddling I have tried seems to cause unexpected results.
Thanks in advance.

Date: 23 Aug 1995 18:37:06 GMT
Organization: Sun Microsystems Inc., Mountain View, CA
Message-ID: <41fsgi$mdq@engnews2.Eng.Sun.COM>
I've been looking through a fair number of examples of NEXTSTEP
programs recently to get some idea of how to handle errors. Most of
the examples either came with the system or were found in NeXTAnswers.
One of the things that I've noticed is that few, if any, of the programs
check to see if the allocation failed. Everywhere I look I see things
like
myObject = [[MyObject alloc] init];
[myObject doSomething];
not
myObject = [[MyObject alloc] init];
if (!myObject) {
// Take corrective action
} else
[myObject doSomething];
The first version, which the examples use, is clearer and easier to code
of course. But what happens when the memory allocation fails? Wouldn't
the alloc return nil and the program have some kind of failure later?
I think I must be missing something since good programming practice
usually calls for making sure that you notice errors like allocation
failure. Why don't NEXTSTEP programs?
How do you handle memory allocation failure. Any insights would be
appreciated since I'm somewhat new to NEXTSTEP programming.

Are you the same person arguing in comp.sys.next.advocacy that

Here you are spouting crap about how Objective-C sould be more

There your are talking how Distributed Smalltalk kicks

Sounds Great. Why not make NKQueue a concrete subclass of NSArray...

I guess the best answer to your question is: Why do it? Since NS is
(currently anyway) running on a virtual memory system, if +alloc returns
nil, you probably have much bigger problems than just an allocation
failure. For instance, if you've run out of swap, your workstation is
about to halt anyway...In fact, it most probably halted before +alloc ever
got a chance to return nil. Also, since sending a message to nil doesn't
cause an error, it's not going to crash the program (I know, not a big
consolation prize).
Basically, people don't do it cause it ain't worth it!

Well, you already answered the question : by checking the return value of
the methods. +new would perhaps return *nil* if it would fail (and -free
would return a non-nil value). That's why it's always a good idea to
assign the return value of -free to the variable.
myObject = [MyClass new];
myObject = [myObject free];
And as to why nobody checks for the return value of +new : (1) it's not
likely to happen and (2) you'll get some other error messages, due to the
failure of the underlying vm_allocate.
If your question is more generally "How does one deal with exceptions in
Objective C ?" There's NX_RAISE, based on longjmp(), and people have also
argued to add Smalltalk-like "Blocks" to Objective C for powerful
exception handling, but I believe the most down-to-earth solution of
checking return values, or using some auxiliary method to check the
validity of an operation, is to be recommended :
[aRecord setAddress:anAddress];
if (![aRecord isAddressValid]) { /* handler */ }
One could imagine that blocks were used as "default" handlers for
exceptions like this, and that you could substitute your own handler
instead of using the default. One could do that.

Message-ID: <41hkgr$be0@sun0.urz.uni-heidelberg.de>
Hi NS gurus,
I got very strange problem. I wrote a daemon, implementing a run method which
basically is an event timer:
- (void)run
{
struct sigvec v;
struct itimerval t;
// Set the time entry (for removing the Autorelease pool
t.it_interval.tv_sec = ST_ATORELEASE_POOL_DESTROY_PERIOD; // 5 sec.
t.it_interval.tv_usec = 0;
t.it_value.tv_sec = 1;
t.it_value.tv_usec = 0;
v.sv_handler = __timeHandler;
v.sv_mask = 0;
v.sv_flags = 0;
sigvec(SIGALRM, &v, 0); // set the handler
setitimer(ITIMER_REAL, &t, 0); // start the timer
sigpause(0); // pause till SIGALRM
return;
}
The reason why I'm doing this is to use the autorelease pool. The time handler
is implemented as follows:
void __timeHandler(int dummy)
{
if (__autoreleasePool) {
[__autoreleasePool release];
__autoreleasePool = nil;
}
__autoreleasePool = [[NSAutoreleasePool alloc] init];
sigpause(0);
return;
}
The daemons runs for a while (say an hour or two) and then dies with
segmentation fault:
Program generated(1): Memory access exception on address 0xbc080000 (invalid
address).
0x784d238 in +[NSThread currentThread] ()
(gdb) where
Reading in symbols for STDaemonController.m...done.
#0 0x784d238 in +[NSThread currentThread] ()
#1 0x780da74 in +[NSAutoreleasePool topPool:] ()
#2 0x780dcf8 in -[NSAutoreleasePool dealloc] ()
#3 0x7832110 in -[NSObject release] ()
#4 0x744c in __timeHandler (dummy=126881376) at STDaemonController.m:69
#5 0x5008888 in _sigtramp ()
#6 0x7480 in __timeHandler (dummy=126881376) at STDaemonController.m:73
#7 0x5008888 in _sigtramp ()
So here are my questions:
1) Is the NSThread class really implemented, or just a hack?
2) Do you have any idea why the daemon dies? Well, I see the [NSThread
currentThread] tries to access a nil pointer, but why after this method was
called already hundreds of times?
3) Does anybody has better idea how to use the autorelease pool in a daemon
(DPS or AppKit should not be used).
Thanks

Here's the scoop:
The C Kit is a core of tight ANSI C code, which we've compiled and
run under DOS, Windows, Windows NT, NEXTSTEP, Solaris, and SunOS. It
should
work fine under HPUX too, but I don't have that on hand.
It forms a basis for most of our work. The NewKit (bad name ;-) is
the ObjC wrapper for the C Kit. So a CHashTable is wrapped by an
NKHashTable. A CList wrapped by an NKList, a CString by an NKString,
etc. There are lots of goodies in the CKit which you get under all
operating systems (unique strings, etc.).
On top of the CKit, we've also built the P-Kit (a very cool object
persistence kit, ask herve@hasc.ca about it) on top of this ANSI
C core, and have then wrapped the Eiffel and ObjC versions of the
P-Kit around the ANSI C core. This gives us code reuse over operating
systems *and* languages. Then, we have an additional HASC Kit,
which stands aside from the CKit as an appkit extender.
+------------+--------------+-------------------+------------------+
| P-Kit Objc | P-Kit Eiffel | | |
+------------+--------------+ NK | HK |
| P-Kit C | | |
+-----------------------------------------------+------------------+
| C Kit |
+-----------------------------------------------+
We sell the whole thing as source code, since we believe in our clients
getting source. God knows we've had to go through hassles with third
party libraries in the past, and we know that having source helps a
whole ton.
Now, that's the background. We've built the API to most of our objects
similar to the old NS API, with some smarter additions. For instance,
it's no problem to an NKQueue if you want to hold ints, void *'s,
char *'s or objects in it. It'll even act properly if you give it
FK objects to retain/release, or char *'s that you insert and want
it to free. The container objects will all do the right thing for you.
We didn't force you into any particular paradigm.
For compatibility with the new FK API's, we've built it as we need it.
There's no big rush until they get everything standardized... but we
do do most of the important things. For instance, you can pass an
NKString to NSString, and it'll work as needed. However, NeXT welds
you into using their objects, since they hardcode it all into their
kits (ie. everything returns an NSString these days, so you can *never*
escape it entirely).
But, it's all available as source as a product. We've sold it, and
it's being used by clients and they seem to like it. The docs
aren't everything they could be, but that's OK ;-).
So, NeXT could always license these objects from us for pretty cheap,
or at least the core stuff, and put it into their object guts.
The NKQueue could drop-in to the NSArray immediately giving huge
performance gains to things like EOF, or whatever, that are
filling and emptying arrays all day. Nobody has ever asked us though,
and they are aware of the performance disparity.
I'm pretty happy though, because I can go over to a Windows program
and use the CKit who's API is so similar to the ObjC API under
NEXTSTEP that I don't have to paradigm-shift my thinking. I think
something like: give me a new list, empty it, add a string object,
and hand it back. I then write:
CList *list = list_new();
CString * string = cs_new("This is a string.");
...
list_empty(list);
list_addElement(list,string);
return list;
-or-
NKList * list = [[NKList alloc] init];
NKString * string = [[NKString alloc] initWithCString:"This is a
string."]];
[list empty];
[list addElement:string];
return list;
And, I always know that it works... no matter what my current language
is, because I'm experiencing code reuse across language barriers.
Anyway, you get the idea.

Yes, it is still free. You can get it from:
ftp://ftp.hasc.ca/pub/next/CrashTrap*
It's one of the objects in the HASC Kit, but we continue to make it
freely available, and post enhancements from time to time. It will
always be free since we want as many people as possible to use it.
One of the good features is to be able to catch the crash, and run an
alert panel telling the user that the application is going down. It's
much nicer than just having your app disappear when it dies.
I think quite a few people are using it these days... I can't think of a
reason why you wouldn't want to, seeing as it's free and you can get the
source, and there's an example for it.

I am trying to add some custom behavior to Preferences. Chapter 14 of

"Building a module is easy, especially since you're provided with a
template (in /NextApps/Preferences.app/Template.bproj) to be modified."
Likewise, notes specific to NS release 3.0 said:
"For an example look at the directory named Template.bproj in
/NextApps/Preferences."
Well, for some reason on my system that file does not exist. I tried
unsuccessfully to hack a Preferences bundle w/o it. If anyone has that
Template.bproj lying around, please send a copy this way. Programming
hints also welcome.
Thanks!!!

This seems to indicate a GET method? yes?
WRONG! This method resets the Text object's frame to the minimum
possible.
Don't call this method if you want to GET anything. This is a SET
method, and the side-effect should be documented as such. I sent a bug
report to NeXT, and we all know how much good that'll do ;)

I believe you can say

Yes, but what if you really really really have to _enfore_
immutability? and it also clearly defines the interface to methods
that take either a mutable or immutable string. Correct?

That's a generalization. Why don't we just have one big class that
does everything then? (Retorical folks)

The retainenous of a Window is a little less important than the

Using the serial port driver that comes with 3.3, two. Using the updated
driver from NeXT, at least 4, but they cannot share interrupts. I'm currently
using 3 this way. Using MUX you can get 8 or more with the correct boards, but
it isn't as easy to use as the new NeXT one. Also, if you're using a serial
mouse, MUX won't support it. The updated driver from NeXT makes serial mice
very usable (they were jerky with the old version).

Message-ID: <41kmoi$198@lastactionhero.rs.itd.umich.edu>
I am having trouble with the following two programming topics:
1. Preventing the NXHelpPanel from crashing on a not availiable find.
I have ran "ixbuild -v" on all of the help files to create the
.index.store. What I can't figure out is why when you search in
the Find section of the help panel on say "flowers", well it doesn't
exist so the help panel crashes the WHOLE APP. Why, am I doing
something wrong?
2. I have a popup button I wish to programmically go to say the 4th
choice on the list, this is the code I have to do this:
[[osServiceType itemList] selectCellAt: [myDelegate _serviceType] : 0];
[[osServiceType itemList]
scrollCellToVisible: [myDelegate _serviceType] : 0];
[[osServiceType itemList] display];
Putting programming style aside, osServiceType is an id pointing to
the popuplist in the NIB. The _serviceType method returns the number of
the item that is to be selected. Am I going about this problem wrong, or
is this really that hard?
I would appreciate ANY and ALL help anyone can provide on these problems.
I have posted them to these groups before, but noone replied.
Thanks in advance....

(gdb) help handle
Specify how to handle a signal.
Args are signal numbers and actions to apply to those signals.
Signal numbers may be numeric (ex. 11) or symbolic (ex. SIGSEGV).
Numeric ranges may be specified with the form LOW-HIGH (ex. 14-21).
The special arg "all" is recognized to mean all signals except those
used by the debugger, typically SIGTRAP and SIGINT.
Recognized actions include "stop", "nostop", "print", "noprint",
"pass", "nopass", "ignore", or "noignore".
Stop means reenter debugger if this signal happens (implies print).
Print means print a message if this signal happens.
Pass means let program see this signal; otherwise program doesn't know.
Ignore is a synonym for nopass and noignore is a synonym for pass.
Pass and Stop may be combined.

What They Need are 30 To 300 % Productivity Gains From People
Getting newer, better computer technology is great, but if the people aren't
highly motivated, highly committed and creative, the $$ investment won't
return what it should. Computer consultants have all learned this the hard
way, but so have consultants on TQM and Reengineering.
What you may not know is that there is a book that really explains all of
this. It is also full of easy to learn and use HOWS to create these highly
motivated people. And it also tells why these hows are the right ones and
why other ways are wrong. The book was written by a boss with 35 years of
in-the-trench experience and it's amazing how what he says makes sense --
like why didn't I think of that? I've seen it in use and the promised 30 to

the card is configured ISA by default and my Dynex has EISA slots, I
went to the section entitled "Using an ISA or EISA adapter in an EISA

The problem is, how can I run 3C509.EXE ... where is it? I believe it

Objects that conformsTo:@protocol(NXReference) won't return nil even if they
were successfully freed as far as their current user is concerned (a design

What error, even if virtual memory would be exhausted before the machine
crashes because the swapfile overflows the hard disk? I think the answer is
just (1), unless it might happen that the object can't be initialised because
any arguments are invalid, or something like that, but not because of memory
issues.
BTW, question to Mike: did you (Sun) talk NeXT into using static typing for
OpenStep, or did NeXT do that to itself?

My thanks to everyone who responded to my question, either via
this newsgroup or via email.
Almost every response I got indicated that nobody checks for allocation
failure because:
1) It almost never happens
2) When it does, your computer usually is in deep trouble anyway.
I did try an experiment and found that my computer (an intel box) does
indeed hang when large amounts of memory are allocated. It gets so
dead that I have to push the reset button.
There was one interesting side note to the responses I got. Every
response from an NEXTSTEP/ObjC programmer said not to worry about failure.
On the other hand, every Unix/C programmer I asked said they always
check every memory allocation for failure. I wonder if this is just
a cultural difference.

If NeXT had a functional setrlimit() command (and proper support for it
built in their window manager and shells) NEXTSTEP application writers
would probably pay a lot more attention to this. I have always been
disappointed with this aspect of the NeXT OS; it makes the thing
extremely vulnerable in that any application (either system or user) can
cause the entire machine to crash, if the application has memory
leaks/bugs. I discovered the setrlimit() problem when a buggy rnews
program was repeatedly bringing a NeXT server down.
Will NeXT fix system resource management in 4.0?

Anyway, go and check out KeyDownBrowser... it overrides Matrix's

Subject: Does Windows 95 really work?
Date: Sun, 27 Aug 1995 15:44:28 GMT
Organization: Netcom
Message-ID: <41q099$m1t@ixnews2.ix.netcom.com>
It's been working great for me (in test versions)
since May.
Because WINDOWS 95 seems to be of almost universal
interest, I'm posting to a wide variety of computer
users.
Take the advice of someone at a lonely computer
terminal who's been around the block a few times.
[E-mail helpme-95@zoom.com for even more info.]
>>>>>Into scifi? Take a look four paragraphs down!
I'm tired. I wanted it easier. WINDOWS 95 has made
it that way. No, the four horsemen didn't make
an appearance when I started using WINDOWS 95, and
it wasn't as important as a Beatles reunion or a Pearl
Jam up-close-and-personal visit or winning a marathon
(or the lottery). I haven't yet felt the aura of
Bill Gates floating about my monitor. (I didn't
notice a halo around his head, anyway.)
WINDOWS 95 does have lots of advantages, though. And
it is important that you make the best possible use
of WINDOWS 95 should you decide to fork over your hard-
earned bucks to get the second coming of WINDOWS.
I have an informative and fun newsletter about the new
stuff--and thought you might like to see it. Free,
of course. I'm cheap, too! Forgive me, I mean
FRUGAL! E-mail me at helpme-95@zoom.com for the
newsletter, and I will be most happy to rush it back
to you.
From one computer user to another--we all try to do this
better and faster whether it's our livelihood or our
hobby. Try me!
C'mon, people, lighten up. It's WINDOWS 95...
Have fun!!!

"The truth is out there." Moldier sighed as he
looked up to the stars in the dark night sky. "Yeah,
sure," replied Scuzzy, "you keep sayin' that but we
never go anywhere except those dark buildings where we
get to use our flashlights." "Trust me." "Yeah,
sure--like I trusted you with my car and you got it
all banged up and then left me in the clutches of that
alien? I don't trust nobody no more." Moldier begged,
"Ah, come on, please let me drive just once more? I
promise no more aliens for this week." Scuzzy mumbled
under her breath something about red shoes and diaries
and handed him the keys.
At that moment, the sky above them came alive with
lights flashing and weird soundss. "What the @#%?><&???",
yelled Moldier as he dove to the ground, grabbing
Scuzzy. It was huge and white and was disc shaped with
two side rockets. It tried to strafe them with bolts
of energy, but luckily missed them. The car, however,
got a toasted paint job and the tires melted.
Meanwhile, above in the spacecraft, a strange being
with pointed ears and his friend were arguing. "Look
at that--you MISSED them! I can't believe this!" The
friend was having trouble. "I don't know what it is--
I know I programmed this scenario okay." "The pointy-
eared fellow laughed and said, "You don't have that
new program from Microsoft, do you? How many times did
I tell you that it'll make your calculations easier and
more accurate? But would you listen to me? Noooooooo!"
Church turned around to take a swipe at Speck,
but Speck was too fast for him and did a tuck-and-
roll out of they way. Church turned again to his
computer screen, but Speck stopped him. "Let's try
this on my computer," he said. Church gave in
grudgingly and Speck set up the run.
Down below, Scuzzy and Moldier were zig-zagging
through the field, trying to evade the alien ship.
I'll get you for this, Moldier," panted Scuzzy, as she
dodged another energy bolt. Moldier was too busy to
reply, since he was sprinting faster than an Olympic-
class runner.
Seconds later, after a particularly nasty surge
of energy, all that lay in the field were two piles
of ash and some melted rubber.
"Got em!", yelled Speck. "I told you that
program was easier to set up!" Church stood by and
glumly replied, "Yeah, but I bet I can beat you the
next system we're in. Let's go someplace we've
never been before." Speck turned to Church and asked,
"Boldly, sir?" "But of course", laughed Church. As
the ship turned and soared away, the two friends
looked out the window up at the stars in the dark
night sky.

Following several replies from USA, I will clarify that the recording is in
PAL format. I believe NTSC is common in USA, and conversion may be expensive.
However, if enough people wanted NTSC I may get a discount for the conversion -
I will find out the cost later this week and post a follow-up.
I had not expected so many would like a copy, so I have not done my homework
on cost of postage to USA - however I expect to be able to provide copies for
15 or at most 20 pounds in PAL format (about 23-30 dollars).
If you are interested, let me know - preferably with NTSC or PAL in subject
header to make it easier to calculate numbers for conversion if it is
financially reasonable.

Paul Heffernan.

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>

You can borrow a DOS boot floppy: Insert it into your computer and reboot
the system. After DOS has booted you can insert the 3Com driver disk and
start the 3C509 diag programs.
But you might also consider not to use the 3C509 at all: This card is known
to have many problems when running NEXTSTEP. Due to very small hardware
buffers this card looses ethernet packets which results in very poor
performance. For further information read NeXT Answers document 1482.

Hi there,
I've got two little questions:
1. Is it possible to access shell-environment-variables inside a
NeXT-programm (developed with Project Builder / Interface Builder) ?
The question is: where do I have to do the proper assignments?
(.login and .cshrc seem not to be the right places ...)
After starting a programm bei clicking into the Workspace-Manager
or via open, the only variables defined are HOME, SHELL, TERM, USER
and PATH.
(The answer I found: Don't use open !
Instead "open <application>.app" use "<application>.app/<application>")
2. How can I access commandline-arguments?
The common way via argc and argv is not very useful, because the
file <application>_main.m is maintained by Project Builder. I should
not change it.
For any advises I'm very grateful,
Oliver

I am wanting to hop between several database backends as I

It would be nice to have a tool which generates a diagram or
even a nice listing from the eomodel files so that I can re-connect
all the relationships and such that I made in EOModeler. Does
such a tool exist? This seems quite laborious otherwise.

How do you subclass NSString and NSMutableString into MyString and MutableMyString without
multiple inheritance (which you don‚t have anyway), or tricks like forwarding to simulate multiple
inheritance?
I think this separation is dumb. And I don‚t care if copy can be implemented with a simple, cheap, retain
for immutable things, because I don‚t use copy anyway (or so rarely...).
I also rarely subclass, so I don‚t care that much about this Mutable stuff but still...

I posted a few weeks ago about an interface between GNU smalltalk and
NeXT's objective-c and received about 20 or 30 responses. I believe
I answered most if not all of them but so far I have not recieved one
god damn response. Hello? If you were or were not able to get it working
let me know, I spent a few month working on it and I would like to know
what people think of it.
For those that didn't get my response, I had a few emails bounce, the
package can be picked up at blackbox.cl.ee.vt.edu. The files to
get are README.rtfd.tar.gz and smalltalk-1.2alpha3.ns.tar.gz. You must
use regular command line ftp and its 'ls' command to see the files, don't
try and get it with a web browser because it won't see the files.
Open the readme and follow the instructions for building it. It should
work on NS 3.2 for intel or moto hardware. If you get it working on
any other platform/version let me know or don't bother to get it.

I am afraid you use copy _very_ often, at least if you use FK
and/or EOF. For example, if you use NSDictionary, you copy _each_
added key.

.cshrc (/etc/zshrc for me) seems to be the right place. At least,

You definitely should *NOT* use command line arguments in NEXTSTEP

Date: 29 Aug 1995 01:23:45 GMT
Organization: The Eye Research Institute of Canada
Message-ID: <41tq72$h03@sator.eric.on.ca>
I would like to use a View subclass I have written to programmatically generate a postscript or tiff
file. Normally this is easy enough using View or NXImage methods, but there is a catch: I want to
do this in a command line program that can be invoked without being logged in at a console.
Is there any way to do drawing with Postscript or with NXfunctions without a connection to the
windowServer which makes the program unable to run as a remote process?
I'd like to be able to do something like this:
NXSize aSize = {300,200};
NXRect frame = {0,0,300,200};
id myImage = [[NXImage alloc] initSize:&aSize];
[myImage lockFocus];
[myCoolView drawself: &frame:1];
[myImage unlockFocus];
// write image to tiff file using NXImage methods
The intended application is a program that would create images dynamically for use in a web page.
Any replies would be greatly appreciated.
Thanks;

Well, *you* don't necessarily use copy very often, Foundation does.
But that's really beside the point. :-)
The reason NeXT's engineers chose to implement immutable base
classes (I'm quite confident) is that for nearly all nonvolatile
operations you gain *HUGE* performance and storage benefits. The
copy-as-retain convenience also saves you from duplicating memory
unnecessarily. If you implemented mutability as a switch in a
single class, you really couldn't make the optimizations.
And those optimizations are needed for something as ubiquitous as
strings. Having an oo interface to strings is a very good thing,
in my opinion, but the price at today's hardware performance is
still almost too steep. Note that the NSValue and NSNumber classes
aren't mutable and don't have mutable subclasses. The performance
*difference* is just too high.

Hi,
I am trying to make an application that uses a PCMCIA Flash RAM as a
simple memory extension.
Thus I have the following questions:
- Are drivers shipped with a PCMCIA board, that will allow me to see my
card as a RAM extension? The reason why I ask this question is that I only
hear about Ethernet and hard drive applications for these boards, but
never memory extensions.
- Is it a big deal to program these cards?
- If no drivers are shipped, is there someone around that has some
solutions to my problem (advice, references, drivers, etc.)
Thanks a lot.

Take a look at this piece of code please. Nothing magic.

const char *fileName;
const char *const fileTypes[2] = {"map", NULL};
char *c;

fileName = [openPanel filename];
if ((c = strrchr(fileName, '/'))) *c = '\0';
strcpy(currentPath, fileName);
[self openDocument];
return self;
}
Every thing looks fine, hmm ??
The ".map" files are of NXTypedStream type and used by no other program.
The problem is that when the user double clicks on a file selection in the OpenPanel the
modal loop "[openPanel runModalForTypes:fileTypes]" is stoped with return value NX_OKTAG and
the system beep is played !!!
Can someone tell what is happening and how can I stop the system beep ?

Nope. NXGetNamedObject returns an object given a specific name, set either via
NXNameObject() or the "Name Object" menu item in IB. You might not care one way or
the other, but the NXGetNamedObject set of APIs isn't part of openstep.
I don't think you can get a list of all the objects created from a nib file. One
alternative solution would be to create a new NSZone into which to load the nib
file, and then when you're done with the nib file, destroy the zone.
Best,
Pete

The original poster is correct (for the most part).
The -copy method will often optimize by simply sending self a retain message
instead of making another physical copy. One of the keys seems to be whether
the receiver is itself mutable or not. Immutable strings do implement copy
using retain.
If you don't believe me, (why should you?), write a simple test program and
see for yourself.
I don't claim that the whole memory management system in foundation is
perfect. Its still unclear in too many situations whether copies are by
reference or by copy, and if by copy whether they are deep or shallow (when
they are containers for example). The reference count scheme breaks down a
bit in the presence of cycles. And there are several inconsistencies in the
implementation of the copy details for example. (no simple rule to apply
throughout)
On the whole though, it is a definite improvement over what came before.

Hi!
Did you ever changed from one Computer with a max ScreenRes of 1024x768 to
a Computer with 1600x1200 and back and forth ....
WorkspaceManager is aware of the Resolution and depending on it you have
different Apps on your Dock! Great....but what's with all other Apps...
And Menu.. I mostly always hide the menu from the screen by dragging it
with its left upper corner to the low right corner of the screen, so that I
could almost see nothing of it but a little black square...and there's
popup on my right mouse button...
All Apps seems to remember that position of the menu or is it WSManager
handling it.
And I drag the menu on that 1024x768 Screen to the lower right, go to the
1600x1200 screen and the menu is also as less seen as on the little screen.
WSManager must be aware of what I'm trying to do.
Now wouldn't it be fine, if any application is aware of the screen res and
would (depending on it) store different defaultbase entries?
If you type in a Terminal:
dread -l | grep DockOnTop here you can see:
Workspace DockOnTopForHt768 0
Workspace DockOnTopForHt1200 0
Workspace DockOnTopForHt600 0
Workspace DockOnTopForHt480 0
Similar thing exist for DockLunchFlagForHt...., DockPathsForHt... ,
DockOriginXForHt (wonder what's that for??) and DockOriginYForHt...
all under Workspace entries of Default Database
Think about TeXview.app:
Every time I start it, the View-window comes up the same place as the last
time it was, when I choosed 'Save' in the Preferences. But every time I go
to that 1600x1200 Screen I have to resize it to a useful size (and what's
big on 1024x768 is small on 1600x1200).
And the zoom and unzoom dpi Setting should be other, too.
There are other topic beside Default-Size and -Position of windows..
Fonts you can read good on a 17" Monitor with 1024x768 are nearly
unreadable on a 21" with 1600x1200...
Do you see an elegant way to handle with this...
Think of Version (I):
I think it is a common problem for every programmer and it could be elegant
if NS would have different Databases for _resolution_dependent_
DataBaseEntries:
1. Each user has a _Resolutioin_Dependant_Default_Data_Base, let's say
RDDDB1600x1200 and RDDDB1024x768 and so on, for each resolution he uses.
So for Edit.app there would be entry:
RDDDB1024x768 Edit NXFixedPitchFontSize 10
RDDDB1600x1200 Edit NXFixedPitchFontSize 14
2. Now I go to that Super Plasma Flat Screen with 2400x1600 pixels
resolution and log in for the first time.. Wow...:-)
With my first login a new RDDDB with name RDDDB2400x1600 is created and all
Values are copied from the RDDDB that is closest to the new ResValues:
RDDDB2400x1600 Edit NXFixedPitchFontSize 14
is created..
I think you got what I mean.
After all there has to be a Resolution INDependant DataBase for things like
Edit AutoIndent YES
Edit PagesPerSheet 1
Edit RichText NO ......
The Problem is, that on some topics the User should have a choice if
Entries are Dependent or Independent like in
Edit HeightInChars 25
Edit WidthInChars 80
(I'd prefer Dependent but other won't...)
Ok, and now Version (II).
The Resolution Dependance could be dependent from
Pixel_X, Pixel_Y and MonitorSize (say Pixels_per_inch_X/Y).
So if the user loggs into a new Resolution WorkSpace Manager could guess
the Values for the new RDDDBnnnn where nnnn is now something like
1600x1200x21 or 1600x1200x17
You can see, that it would be a difference to have 1600x1200 on a 21" or a
17" Monitor, because the dots_per_inch is different and so you would have
to choose different font sizes in Edit to have the same REAL font size.
So what do you think about this new concept of DataBases...
There shouldn't be a Problem for NeXT to handle this from DefaultDatabase
Manager....
Or is there a way to integrate a FILTER between the Database Mechanism and
the Application asking for a Entry... Filter (with a loginhook) could do
the job, but I'm not that firm in FILTERs that I could see, if you can
cover a Database with it:

Hi,
I would like to archive some objects using NSArchiver and NSCoder.
By the Object class there are functions like NXWriteObject() and
NXWriteObjectReference(). Does encodeObject: automaticaly encode by
reference or there is another function for that purpose ?

I want to save screenshots as eps files, not for saving disk

If I convert Grab's tiffs back to eps, files take approx. 1.5 mb,
while the ps information sent to DPS takes about 15k, which ist quite
a difference.
Is there a way, to send something like copyPSCodeInside: to a view,
which is not part of my own application?
step one: figure out, whichs view ist beyond the mouse
step two: get its eps info...
any ideas? I just can't make students download a 200mb file for easy

While this approach will certainly destroy all memory used by the nib
objects, my experience indicates that it will likely cause problems
because many classes depend on their free/dealloc method to clean up
properly, etc.
Most nibs contain mainly UI objects which can be released by merely
releasing their window (note the glaring exception of popUpLists which
aren't views and must be released explicitly - this will change in
OpenStep, I believe). So the real work involves releasing non-view
objects which must be released in the same manner as objects not created
from a nib - by following references and releasing explicitly.
Of course, you could use a shortcut and in each custom nib object's
awakeFromNib, add self to an array accessible via a well-known object like
NXApp's delegate. Then at the proper time, you could release the array's
contents.

Cheques (checks), euro-cheques, sterling bankers draft are acceptable -
preferably in sterling, otherwise use current bank exchange rates and add four
percent to allow for bank charges when I convert to sterling.
I can accept 24 dollars for PAL format and 39 dollars for NTSC format from USA.

It's perfectly fine to access command line arguments in NEXTSTEP
apps, and you don't have to modify the _main file to do it...the
command line arguments argc and argv are assigned to the global

Is it possible to get the sender of a method, even if there's not an
argument like 'sender'?
I want to override the method 'cellAt::' of the matrix class to have a
special behaviour. But this method is used extensively from the matrix
class itself in its drawSelf:: method and I'm too lazy to override this
method too. So if there would be a way to get the sender of a method, then
my cellAt:: method could perform its special behaviour only if its not
invoked from the matrix class.
But I guess its not possible, so I also have to override the drawSelf::
Or?

The compilation produces one warning:
However, many tests involving files (exec, file, glob, source, pid, open)
fail with error messages:
couldn't create error file "" for command: File exists
or
couldn't create input file "" for command: File exists
However all "real" tcl scripts I run until now, do not show these
problems.
In a previous posting in c.l.t, Hadar Pedhazur <ubs!hadar@uunet.uu.net>,

Perhaps /lib/posixcrt0.o in NS3.2 developer does not define these.
In 3.3 Developer they are defined there.

I suggest that you run nm on both /lib/crt0.o and /lib/posixcrt0.o
and compare the output.
To work around this, you might try reversing the order of your library
seaches. You search libsys_s before libposix. Try reversing that.

GNUStep`s Foundation Kit is going to be part of libobjects, and some
classes are already implemented, but unfortunately, it won`t work on
NEXTSTEP. Sorry.

Upps! Not very true! One can use the both NXArgc and NXArgv global variables
(they have the same scope as NXApp).
If you already are using the Foundation kit, than the best way is to use the
NSProcessInfo. I wrote one free implementation for the GNUStep's libobjects,
but the class can be used separately too. This will solve the problem for
accessing the environment vars either. BTW, GNUStep's NSUserDefaults is also on
the way....

I've seen this before. As far as I can remember, it's a strange bug. From time
to time it works for me fine, but sometimes it beeps ;-)
I think Art Isabel had a solution or comment on that same subject, but I can
really not remember the work around ... may be you can ask him

I reported this behavior as a bug to NeXT for certain of their apps
(e.g., ProjectBuilder). Later, someone posted what causes this, and I
can't recall the details :-) But I believe it's a programming "bug" that
can be avoided by the way one writes OpenPanel code.

This is basically what we are doing, in lieu of not being able to get the list
of objects for a nib. We are creating subclasses of EOController
and Object (which poseAs these respective objects), that
implement awakeFromNib and register the object with a subclass of EOApplication. The EOApplication subclass overrides the loadNibSection: methods to
create a list of instance objects for each nib. We then ask the
applciation to close the nib for the file owner when it is
dealloc'ed. This releases the list of instance objects.

Organization: Erindale College, University of Toronto, Canada
Message-ID: <424luo$bg1@tuzo.erin>
I have been creating TIFF images with 16 bits per sample. Unfortunately none of the image viewing programs on the NeXT which I have used will display these. OmniImage, PiXel, FastView all accept the image but display nothing. Image Viewer displays a message indicating it can't read the file. In all these cases the console displays the following error message...
TIFF Error: Image parameters not acceptable: w=100 h=100 bps=16 spp=1 alpha=0 photometric=1.
I suspect that the TIFF routines provided with the operating system barf on 16 bit TIFF's. However can't find any mention of this restriction. Does anybody know of this restriction ? Is there any way around this, i.e., are there any programs which can display 16 bit TIFF's on the NeXT (Intel Hardware) ?

This would be useful. Of course, it should build on the GMT time based

Greetings,
I am using the Indexing Kit to query my IX DB.
Example of what I want to do:
Class 'Dog' has method
- (integer) age;
that returns age of dog to nearest year.
I have an IX file containing instances of class Dog. I want to get all
instances where age is 5. Currently, I would have to write a hack function
- (char *) ageAsString, and use this key. I want to use the function that
returns an integer. Has something to do with Comparitors? Unable to grok
documentation.
Any ideas, please, I am at a loss. Thanks.

Hmm. Those errors relate more to precision testing errors. The error
messages that the original poster posted don't suggest those kind of
errors.

That's right. These errors break the test script, such that it is
necessary to comment them out to run the following tests. If someone

yes, there is a foundation kit included in libobjects (ftp://prep.ai.mit.edu)
but it will not work on NS for HP and it's not a replacement for the
Foundation, coming with 3.3 because the GNU runtime is different

# Hello,
#
# I am trying to get the test suite completed for tcl7.4p1 on a
# NextStation running NS3.3 Developer.
#
# The compilation produces one warning:
#
# However, many tests involving files (exec, file, glob, source,
# pid, open) fail with error messages:
#
# couldn't create error file "" for command: File exists or couldn't
# create input file "" for command: File exists
Could be a tmpnam() problem [described below] or could be a direct * vs.
dirent * problem...
This was one of the problems I had to fix when compiling the Definitive Tcl
7.3 release for NS [I have since abandoned Tcl due to serious performance
flaws inherent to its current design-- hopefully, Sun will be fixing these
problems in the next release].
Basically, the tmpnam() routine supplied by NeXT is broken. Specifically,
tmpnam() can only be called TMP_MAX times [which is hardwired to 25!!] --
after that, the behaviour is *undefined*.
mktemp() works, however.
I placed the following in compat/tmpnam.c:
#define P_tmpdir "/tmp"
char *
tmpnamTcl(s)
char *s;
{
static char name[50];
char *mktemp();
if (!s)
s = name;
(void)sprintf(s, "%s/XXXXXX", P_tmpdir);
return(mktemp(s));
}
Notice that the function name is changed to tmpnamTcl-- this avoids
namespace collisions when linking (and is a good idea for ALL compatibility
functions). I then changed all references to tmpnam to tmpnamTcl.

Does Grail use any Tcl-- I don't think it does... isn't a Tk on Python
environment?

It IS very likely that it will fail. Since it works at all, it is likely
not the direct * vs. dirent * problem-- but the tmpnam() problem instead.
Also, when performing the tests, make sure you are doing so on a local
directory (not an nfs mounted directory). The .nfs files will prevent Tcl
from unlinking certain test directories and will produce spurious errors.

Thanks Bill! Having never actually "looked" at the code for the
Tkinter stuff in python, I don't really know. However, from
reading the newsgroup relatively religously, I got the impression
that while there was a native interface to Tk, one could use Tcl
stuff "within" the Tk portion. In other words, python can call
Tk directly, and requires zero Tcl, but while in Tk routines, Tcl
would be supported.
Of course, I could have misunderstood completely :-)

Hi,

Does anyone have a simple client/server application to illustrate how
DO works. I have tried on my own, but I am not sure what I am doing
wrong or right for that matter:
//Client:
I am decalring a protocol for the client
I make the client comply with the protocol
I define the methods in client.m
then I creat a proxy, and attempt to send a message to the
server by name.
//Server
I am declaring a protocol for the server
I make the server comply with the protocol
I define the methods
I vend the server as Root get the NXConnection object and let it run.
it does not work.
I am missing any steps here?
Thanks in advance for your help.

I'm very new to the NeXT dev environment and am using it as a student.
Writing anything usually involves l.lists of course and I really want a
linked list for my little application. So I thought to myself this
can't be too different to other projects under other environments and I
made a header with the approximate structure:
/* blah blah blah */
typedef struct __list *plist;
typedef struct __list
{
id pageScrollView;
id pageView;
id Window;
plist next;
} LIST;
/* blah blah blah */
@interface...
Well I was surprised to find that didn't work because I need the typedef
2 B the type for an instance variable. I read the appropriate librarian
file on objectC and couldn't fathom it out and couldn't easily find an
example anywhere - can somebody shed some light on this problem?

I am pretty happy with my Courier V.E/V.34 external modem. It works fine for PPP. I have
not found a working FAX software yet. (Jollys Fax Class 2.0 does not work with it). Your
mileage may vary, as it depends what modem is on the other side of the line. If your
Internet provider has Couriers this modem is IMHO the best way to connect.
Maybe we should redirect this thread to c.s.n.hardware?

Read the Concepts/ObjectiveC section of the NextDev documentation to get
an
introduction to ObjectiveC. The '@interface' construct in you code is used
to define an ObjectiveC class. You really don't want to define a linked
list
struct, you want to define a linked list class:
#import <objc/Object.h>
// Define the LIST class instance variable and interface(methods)
@interface LIST : Object
{
id pageScrollView;
id pageView;
id Window;
LIST *next;
}
- init;
..
@end
// Define the LIST class methods
@implementation LIST
- init
{
..
}
..
@end
This introduces a user defined class of type LIST *. To use such a class
you
would do something like:
LIST *aList;
aList = [[LIST alloc] init];
// Now add some items to the list
[aList addItem: someItem];
...
You would only use a 'typedef struct ...' in ObjectiveC to introduce an
aggregate data type that you don't want to assocation any
behavior(methods)
with. Otherwise, you want to use an ObjectiveC class.

{
char *ribCode;
RtToken ribCodeResource, ribMacro;
}
- (void)loadRIB:(const char*)filename
// should be called after the shape was added to the shape-hierarchy

ribCode = malloc(...allocte space for the rib-file....);
read(... read the rib-file....)

ribCodeResource = RiResource(resourceName, RI_ARCHIVE, RI_ADDRESS,
&ribCode, RI_NULL);
ribMacro = RiMacroBegin(resourceName, RI_NULL);
RiReadArchive(ribCodeResource, NULL, RI_NULL);
RiMacroEnd();
}
- free
{
RiFreeHandle(ribMacro, RI_MACRO);
RiFreeResource(RI_ARCHIVE, ribCodeResource);
}
- renderSelf:(N3DCamera *)theCamera
{
RiAttributeBegin();
RiMacroInstance(ribMacro, RI_NULL);

return self;

Try using 'whole' instead of 'eq' - and don't let'em fool you! Not half of

In my application I'm loading several .nibs, each containing a menu.
I include the nibs menus in my main menu as submenus.
But after loading (or while loading the nibs) each of the nibs menus
overrides my main menu.
So at the end of loading all the nibs I set the old main menu again as
menu for the application.
This seems to work, but the menu isn't visible anymore. Only after I select
another running application with a menu and then switch back to my application
my old main menu with the new submenus appears on the screen.
Is there a way to let it appear immediately?
I tried the following stuff.
..
loading the nibs with [NXApp loadNibFile:"..." owner:self withNames:NO];
..
including the nib menus into the main menu:
[mainMenu setSubMenu:nibMenu forItem:nibMenuCell];
..
now trying to redisplay it:

[mainMenu sizeToFit];
[mainMenu display];
[NXApp setMainMenu:mainMenu];

Date: 3 Sep 1995 20:39:23 GMT
Organization: University of Otago, Dunedin, NZ
Message-ID: <42d3pr$32o@celebrian.otago.ac.nz>
A few days ago, someone suggested that it would be a good idea to have
menus that could be dragged off to create custom menus for the menu items
you find useful. I thought this would be a good idea, so I set about
implementing it. I'll be making the source publicly available when I have
worked out the last couple of bugs.
So far, I have got the creation of the custom menus working (you just
alt-drag a menu item off), the addition of items on to the custom menus
(alt-drag the menu item onto the custom menu), and the deletion of custom
menu items (by control-clicking on them).
Now for my problems:
1. The main one at the moment is archiving and unarchiving the menu items
I have added. What I tried to do was to use a NXWriteRootObject() for each
of my main menu menucells which had a custom menu attached to it, and thus
wrote the cells and their submenus to my file. When I reload the menu
cells from the file and put them in my main menu, they appear ok, and have
their submenus, but there are a few odd things start happening. You
sometimes have to click twice on the item to make the submenu
appear/disappear. The submenu items don't display their hotkeys any more
(although the items still work). When I try to remove a custom menu item
from the main menu, it gives me postscript errors and falls over. And
other weird behaviour.
2. I don't know how to get rid of a submenu cleanly. When you
control-click on the last menu item in a custom menu, I want to remove the
supermenu's item controlling this menu (this works), and then free myself
(the submenu). This doesn't work (even using perform:with:afterDelay:),
and when I next go to use the main menu, it says I'm trying to talk to a
freed object. As a work around, I just close the menu, and as you have no
way of reopening it, it is effectively gone, and it is not archived and
reloaded. NeXT must have a solution to this as they do it in edit when you
close your GDB windows.
3. Just a question or two - how would I go about getting Workspace to load
something like this as a bundle? Would it be possible to make all
applications have this feature automatically (I use poseAs to become the
Menu class)? I guess I could just alter it a bit so that it was a palette
object that you could put in any application's nib file. It would then
make that application custom menu aware.
If anyone would like to help me on this, please send me suggestions, or if
you would like to have a look at my code with a view to helping, I can
nextmail you my trial project.
When it's finished, I intend putting the source on the archives and
submitting it to MiskKit.

news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs

[from the document ftp://ftp.next.com/pub/NeXTanswers/1000_Help]
Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.
USING NEXTANSWERS BY FAX
To use NeXTanswers by fax, call (415) 780-3990 from a touch-tone phone and
follow the instructions. You'll be asked for your fax number, a number to
identify your fax (like your phone extension or office number), and the ID
numbers of the files you want. You can also request a list of available
files. When you finish entering the file numbers, end the call and the
files will be faxed to you.
If you have problems using this fax system, please call Technical Support
at 1-800-848-6398. You cannot use the fax system outside the U.S & Canada.

I've got a menu item which sets off a method in my program that can
(potentialy) run for rather a long time. While the method is running its
peeking the event queue, and will take appropriate action to handle any
incoming events, so it looks to the user as if the main event loop is
still running.
This all works fine, except that the action sent from the main menu
still hasn't returned, and hence the menuCell is still highlighted. This
is very distracting for the user - particularly as its perfectly
reasonable to retriger the highlighted cell (yes - this works, but don't
try it at home kids!).
I've tried every obvious was I can think of to switch the highlighting
off, but the cell will simply not unhighlight!
I've tried all variations of:
[sender setState:0 at:[sender selectedRow]:[sender selectedCol]]
[sender setState:1 at:[sender selectedRow]:[sender selectedCol]]
(sender is a Matrix)
temp=[sender selectedCell];
[temp setState:0];
[temp setState:1];
[temp setIntVal:0];
[temp setIntVal:1];
(temp is a menuCell)
with various displays afterwards, and none has any affect.
Has anyone had any succsess in doing this?
I'm sure it must be obvious, but I've tried everything I can think of...
Thanks,

Not easily, no.
If you wanted to go crazy about this, it is theoretically possible to unwind
the stack from your current stack frame and determine what the sender of the
current method is. This might even work reliably on the Intel and Motorola
platforms, but this may not be possible to do reliably on the SPARC, and it's
definitely not possible to do this in all cases on the HP.

The bug is in the openpanel; it's not yours to fix. What is actually

attempt to deliver an event to a window that no longer exists, and

Thats quite simple. Use the preprocessor directives #warning and #error,
e.g.
#warning This is a warning

[stuff deleted];
I don't know how to unhighlight the button cell other way that you use,
but I suggest you to use different approach. I would use the
perform:with:afterDelay:cancelPrevious: method to call your method working
the event queue.
- your_old_action_method_running_for_a_long_time:sender
{
......
}
- new_action_method:sender
{
[self perform:
@selector(your_old_action_method_running_for_a_long_time:)
with:sender afterDelay:0 cancelPrevious:YES];
return self;
}
This way the action method returns and the menu will be unhighlighted
automatically. Your old method will be called from the main event loop.
I hope it helps you.
Best regards,

Hi everybody,
We've a small problem on EOFModeler with ORACLE.
When we've same table names on different user spaces,
we get "something like a merge" of all the tables with EOFModeler.
I guess this is a problem with our NeXT environment database concerning
the Oracle7Adaptor variable.
We've defined Oracle7Adaptor like this :
Oracle7Adaptor OracleTableNamesSQL "SELECT OBJECT_NAME FROM USER_OBJECTS
WHERE OBJECT_TYPE = \'TABLE\' OR OBJECT_TYPE = \'VIEW\' ORDER BY 1"
Could you help us ?
Thanks.
Example of our problem:
-----------------------
$ sqlplus zob/zob
SQL> describe solde
Name Null? Type
------------------------------- -------- ----
EXR_EXER NOT NULL VARCHAR2(2)
GES_CODE NOT NULL VARCHAR2(3)
PCO_NUM NOT NULL VARCHAR2(6)
SLD_SOLD NOT NULL NUMBER(12,2)
SLD_DATE DATE
$ sqlplus foo/foo
SQL> describe solde
Name Null? Type
------------------------------- -------- ----
SLD_EXER VARCHAR2(2)
SLD_IMPUT VARCHAR2(6)
SLD_GEST VARCHAR2(3)
SLD_SOLD NUMBER(12,2)
SLD_DATE DATE
SLD_STAT VARCHAR2(1)
But on EOFModeler (both with zob and foo user)
we have the following properties :
EXR_EXER
GES_CODE
PCO_NUM
SLD_DATE
SLD_EXER
SLD_GEST
SLD_IMPUT
SLD_SOLD

We are looking for a Documentation Generator that will split out
definitions for multiple classes declared within the same file. We
would like the output to be exactly like that generated by docgen.
Currently we have used a separate program to parse the multiple
definitions into separate files, one for each class, and then call
docgen on the working directory. The problem is that docgen then read
the path to the temporary files and lists that in the Declared In:
line.
We know it is possible to use -e to specify a string for Declared In:
but there is now way to do this with multiple files being parsed from
a temp directory.

Hmmm... sorry if my question wasn't clear. I meant how to output messages

Message-ID: <42jqj7$9ic@styx.uwa.edu.au>
Hi all,
I upgraded to 3.3 recently (Intel) and have encountered a problem with an
app which compiled properly under 3.2.
Using MiscKit 1.5, I had added the MiscKit and MiscValueField libraries
and modified the OTHER_LIBRARIES = -L/LocalDeveloper/Libraries.
There are several other libraries added into Project Builder. The project
consists of a sub project also. This app now compiles as before but
generates a LIBRARY_PATHS = -L in the main Makefile. This causes cc to
bomb out when linking reporting a -L on it's own:
ld: -L: directory name missing
This is directly followed by the -L/LocalDeveloper/Libraries parameter.
make clean, and removing the Makefile (as it's generated by Project
Builder) still causes the same problem, changing the project and resaving
also repeats the problem.
Anyone discovered this one before? :-(
I've yet to upgrade MiscKit to 1.6.1, perhaps that's it?

I am trying to get the list of fonts that would appear in the Font Panel.
If I use FontManager's -availableFonts method, it returns all the fonts that
I require, but also Lexi. Lexi appears to be a pseudo-font - containing many
nonprinting characters and a few symbols.
I could compare the familyNames of fonts returned by availableFonts for Lexi,
and exclude it that way, but that would not help if there are other such fonts
on other machines.
Is there some other way of getting the list of fonts that would appear in the
Panel or some way to identify those fonts returned by availableFonts that are
not displayed in Font Panel?
Many thanks,

I tried compiling the program without these libraries but the linker

Hi,
it's probably a FAQ, but...
There is a package, util.c, which comes with NCSA's httpd. Included in
util.c is a function that decodes characters encoded by the web-browser. The
function is:
char x2c(char *what) {
register char digit;
digit = (what[0] >= 'A' ? ((what[0] & 0xdf) - 'A')+10 : (what[0] - '0'));
digit *= 16;
digit += (what[1] >= 'A' ? ((what[1] & 0xdf) - 'A')+10 : (what[1] - '0'));
return(digit);
}
But the function returns bad digits for charakters like " and so on. It's
clear that this problem comes from Next's own caracter-table.
The question is: how can one solve this problem? The best were a modified
function, of course.
Thanks,
Rainer

Yes. Mike Paquette, who's *the* NEXTIME developer at NeXT (yup, there's
only one!), told us at the Object World Multimedia BOF that "2.0" would
ship as part of NS 4.0, and include headers, classes, some documentation,
and an example app.

I'm not yet very familiar with the NS3.3 makefiles but I think if you are
setting variables in a Makefile.preamble, I suspect they should be
something like:
OTHER_LIBRARIES = -llibMiscKit.a
LIBRARY_PATHS = -L/LocalDeveloper/Libraries

Hi Rainer,
Looks to me like this is a function to convert a two digit hexadecimal
string (e.g. "8F") into an 8-bit number -> so a character such as '"'
would be invalid input for the function. Since it shouldn't be passed
such stuff, the problem must be before this. I don't know in what context
this function occurs, but might it be the result of a badly formatted
web page ?
Cheers,

As an Inexperienced NeXTSTEP programmer i need some help with getting my
Custom View to display itself quickly. I am tring to build an app which
simulates the game 'Life.' Basically, I have a custom view, LifeView, which
among other things holds a two-dimensional(NxN) array of boolean values. I display
the view so that each array element represents a square of one of two colors
and fill out the view with these squares (NxN). currently I do these by having
the LifeView's drawSelf:: method invoke a pswraps function(which draws a
single square, in the appropriate place) for each elememt of the array.
Well... this doesn't work very quickly. The actual code of calling the
pswraps function NxN times is executed, of course, rather speedily, but the
displaying of the LifeView is NOT, esp. as N gets large. I know that this has something to do
with the DPostScript interpreter, but even if I only draw one square out of the
NxN squares/array elements, it takes just as long. I've tried working with
multiple threads, but i'm not really doing anything else simultaneously, so
fundamentally, i don't see any advantage there... Anyway, if anyone has a vague
idea of what i'm tring to explain and/or any suggestions....thanks.

Organization: U of Wisconsin CS Dept
Message-ID: <42ljah$svf@spool.cs.wisc.edu>
Does anyone want to be able to kill apps with a mouse click (ie without
activating them)? Here it is! I should warn you that this will just kill
the app -- it will not give you a chance to save files, nor will it bring
up a nice panel asking if you really meant to do that.
To use it, simple hold down alternate and right click on any window owned
by the application or its icon on the dock. This will not kill some apps
like Terminal because they run as root.
In order to install it, you will have to edit
/usr/lib/NextStep/windowpackage.ps. Make sure that you make a backup of
this file before editing it! It is owned by root, so not just anyone
can do this. Below are the lines that should be inserted (somewhere around
line 1319 on 3.3 systems). You end up replacing rmdownEvProc, the procedure
that gets executed when a normal window receives a right mouse down. The
commented out procedure at the bottom shows what the original looks like.
Disclaimer: you should not attempt this if you do not know what you are
doing. You may be unable to log in (you will have to boot single user to
restore the windowpackage.ps) if you mess it up. You can kill apps that
you did not mean to kill. I cannot be responsible for what happens!

sorry for my repeating this request: really there is no way to get

keys)? Something like the PSbuttondown() function, but for the
keyboard and not the mouse...
The events are good for nothing - the NX_FLAGSCHANGEDMASK event is
sent only to the active application :( (BTW - and this is IMHO
really a bug - if you deactivate an application with the
NX_FLAGSCHANGEDMASK bit in the event mask, then change the modifiers
state and then activate the application, it is *NOT* sent the
event!)

James: You _must_ get the Adobe purple book. There's a function
specifically for displaying arrays of rectangles. I can't recall the
exact usage, as I don't have the book in front of me, but that'll be what
you want.
Essentially, you'll have all rectangles with the same attributes (color)
in separate arrays, then display them using this function.
I just looked, there are NX functions to do the same:
NXRectFillList() fills a list of count rectangles with the current color.
Both work through the rectfill operator.
NXRectFillListWithGrays() takes a list of count rectangles and a matching
list of count gray values. The first rectangle is filled with the first
gray, the second rectangle with the second gray, and so on. There must be
an equal number of rectangles and gray values. The rectangles should not
overlap; the order in which they'll be filled can't be guaranteed. This
function alters the current color of the current graphics state, setting
it unpredictably to one of the values passed in grays.
Hope this helps,
Dave

Message-ID: <810467300snz@cedar.demon.co.uk>
The NEXTSTEP supplied spellchecker (as used with edit) gives some strange
guesses for English words. e.g. when encountering 'wordcount' it suggests
'wosdcount'; when encountering 'spellchecker' it suggests 'spellchecnker'.
Is it possible that I have some localisation problems with my installation?
Does anyone have any idea if this is my problem or is it just a poor spell
checking routine?
If it is the routine, are there any alternatives available, or any work-
arounds.
Thanks,

Also you may try [NXImage composite...]. Check the window depth. 24bit
composition on a 8 bit screen wastes time. In general,
Concepts/Performance/C_ImprovingDrawingPerformance.rtf is the right docu.

Subject: Unix System Calls on NS 3.2

Organization: I DID NOT CONFIGURE MY ORGANIZATION IN MY NEWSREADER
Distribution: world
Message-ID: <42mtnq$e7i@eurybia.rz.uni-konstanz.de>
Hello,
A friend of mine has encountered the following problem, when he tried to access
the unix system call "chdir" on his NS 3.2 machine.
Consider the following short program:
int main()
{
char *name;
name = "/somePath";
chdir(name);
return(0);
}
The main point is the call to "chdir". The right declaration reads
int chdir(const char *path);
It is possible to compile the program without declaration, and as expected you
get the warning "implicit declaration of chdir", but it works. Because we are
not satisfied with this, we tried to find the right header file to include. The
two candidates we found were "libc.h" and "unistd.h".
Wether on of the two possibilities works or not depends on
1. the compiler we use
cc (which is gcc 2.2.2 in NS 3.2)
gcc 2.6.3
2. wether we name the program
test.c (which means it is a C program)
test.cc (which means it is a C++ program)
3. and it depends on preprocessor flags we set
-posix
-ansi
-traditional
no flag
So we looked closer at the files and we found, that there are actually two
versions of "libc.h" and "unistd.h". The second versions seem to be created
when "gcc" was compiled and should be "fixed". They reside in
"/usr/local/lib/gcc-lib/i386-next-nextstep3/2.6.3/include"
Because for "gcc" this path occurs in front of the usual system search path for
header files and so "gcc" finds this versions, but "cc" doesn't know anything
about them.
The question is now, which is the right header file to include at the top of
the above program?
What are the right flags to use?
Are there general guidelines?
This is a rather lengthy post, but we have found out a lot about the problem
and cannot not solve it.
Thank you in advance

To reduce the performance penalty of the actual rectangle drawing, I would use an NXImage that was
the size of a single pixel and appropriate color. You can then lock focus on your view and
compostite it to each point that is currently populated. Another performance penalty that you may
be paying comes from rapid calls to the main views display, or atleast the lockFocus. You would
like to have this lockFocus be done once of course, and as fast as possible. Try using gstates
(I've think this help, althought I know nothing of how to use them), and instance drawing (although
it may cause you too much flicker).
Finally, I would keep track of 2 extra bitmaps. One for squares that need to be turned off, and
one for squares that need to be turned on. This way you don't draw every pixel every time. If 2
extra bitmaps takes up too much space, use them as true bitmaps and have fun with bit - twidling!

I have also experience the reverse stack-frame problem. I was told by someone that it is possible
to grab some pieces of gdb from 3.2, put it in place of some of the 3.3 stuff, recompile and go.
Only problem is, I don't know what piece that is? Any one who knows the answer, please let us
know.

DevMan is an awesome package! Get it, use it, be happy!
I find that the user interface leaves a little bit to be desired, but the
command line tools are extremely intuitive, provide all of the power of the
UI (plus a lot more), and are a joy to use.
As well, once you grok the zen of map files, managing complex projects that
contain many subprojects is a breeze!
BTW: I have written a set of html tutorials of how to:
- set up your environment for effective use of the command line
- how to create repositories/work areas from the command line
- how to create/install/use map files
- how to automatically create change logs in your code
- how to automatically stamp binaries with version #s for ALL classes
If there is enough interest, it might motivate me to actually publish the

The only thing I'll add to bbum's recommendation is this: ProjectBuilder
builds apps fine, but it does not scale to large systems. With DevMan's

I would suggest using a NXBitmapImageRep directly. Allocate it and initialize
it to the dimensions of your data. Then use [... data] to get a pointer the the data array. Then all you have to do is modify the bits. If you use 8 bit
greyscale, it will still be fast, and you'll have 1 byte per box. Then use
[... drawIn:] to display it. This should be quite fast and easy!

In ProjectBuilder go to Builder and then klick the "Options..." button.
Then in the scroll view above the three buttons make sure that there
is _no_ blank line. If a line highlights, then there's a blank line
and this generates the "LIBRARY_PATHS = -L" with no arguments in the
Makefile which causes cc to bomb.
I do think that this is a bug because if there's nothing to see in this
view then PB shouldn't generate this "LIBRARY_PATHS" line.

Assuming you are drawing the whole LifeView every iteration, an interesting
technique could be to use a NXBitmapImageRep in which you twiddle pixels on
and off, then use drawInRect: to draw it magnified. This should be fairly fast
if your magnification factor is an even integer (which is probably what
you want anyway).
For instance, displaying a 160 x 160 12-bit color life game in a 640 x 640
color view takes about 150ms on a pentium 60. If you choose not to scale,
then the same operation (160x160) takes about 17ms and 640x640 takes
about 200ms. Not too bad.
Note that although it might be nice to use a 1-bit deep NXBitmapImageRep,
that won't necessarily give you the best performance. You will get the
best performance when the depth of the bitmap matches that of the window.
(You can assure this by asking the window what it's depthLimit is, or if you
don't need color at all, you can just go ahead and always use a 2-bit
grayscale bitmap...)
Twiddling pixels on and off requires using methods in NXBitmapImageRep
to find the right byte number in its bitmap array and then or'ing your
pixel in. If you've dealt with bitmaps before this should be fairly
straightforward.
One decision you have to make it whether to simulate the game in your array
of BOOLs and then recreate the contents of the whole bitmap, or simulate the
game in the NXBitmapImageRep...
There are several other approaches (userpaths, actually creating a font,
compositing), some of which are detailed in the "purple book" from Adobe:
"Programming the Display PostScript System with NeXTstep".
If you have one handy you might want to browse through it... I don't
know how fast the approach of using an NXBitmapImageRep is compared to
the various other solutions, but it might be fun finding out.

For an example of a pretty fast implementation of Life, you might
check out the SparseLife BackSpace screen saver.
You can use archie to find out the ftp site (its probably on
oregon and peanuts)
I wrote a moderately speedy version that used NXRectFillList
to output a bunch of rectangles quickly. Someone (I forgot
who, sorry!) modified it to use a sparse algorithm so it doesn't
have to compute or flush unchanging areas. Very smart and fast!
The implementation is neat too because cells change color as they
age. The filename is SparseLifeView.

Hi, netter,
I want to implement a primitive terminal emulator on NeXTSTEP. There is an examples called
"Subprocess"
by Charles L. Oei
pty support by Joe Freeman
Subprocess Example, Release 2.0
NeXT Computer, Inc.
(It is normally installed under the directory: /NextDeveloper/Examples/UNIX/Subprocess, Further
descrition can be found in read.rtf) The Subprocess object facilitates the management of concurrent,
asynchronous UNIX processes within a NeXTstep application. Methods are provided for the creation,
termination and communication with the underlying UNIX process. I compile this example without
changing and start MyShell, as they call it. It seems working but a main flaw is :
- If I work on the local machine (the machine where I start MyShell), everything is OK, but if I
login on another machine, the echo comes twice.
- How can I do if I want to make the the password invisible in my terminal emulator?
If any one has the similar problem, please send me your sugguestion. If you have already implement
that, it would be very kind of you to send me the code. What I need is a primitive terminal emulator.
Thanks in advance for your help.
Niandong

I found two ways. A ugly one, using nlist and reading directly in kernel
memory. I can send you the source if you ask (and if I find it back)
As there are many limitations with that (you have to 'busy' test cause you
have only the current event state, and it is non-portable, even between
different flavour of NEXTSTEP), I went to another solution, at least as
ugly, that patch the windowPackage.ps to send a signal to a determined
process when a certain flag combination arise. This one is a bit more
portable, but you have to patch the windowPackage of each machine you want
your a run on.
So, question:
Does anybody know how to patch the windowPackage from a running app ?
It should involve something like true setshared followed by eeehh, well I
think there is a permission problem at that point...

Hi All,
I have a few TextFields grouped together in the ScrollView. When I put the
cursor in (for example) the first TextField and than I scroll the field
out and in, the text in that field is corrupted. If I group the TextFields
in the Matrix and than to the ScrollView everything works fine.
Does anybody notice this problem? Is this a known bug or I am missing

Yes, you can do a lot of stuff that way:
currentshared
true setshared
windowPackage begin
% do stuff here -- you can mess around with a lot of things at this point.
% hwoever, I think your mod requires changes to the event handlers for
% each window, which is a bit harder to do.

setshared

I am trying to compile bison-1.24. The configure program sets it up for

CPPFLAGS = -ansi. All goes well until the link stage when I get an
error on an undefined symbol -- _alloca.
I grepped for _alloca in all the *.[ch] files and it does not seem to be

Hi, all. Hope this isn't too obvious...
I have a simple subclass of View that does some stuff; I've written a couple

app when my initFrame: frameRect method is called, frameRect is NULL. Happens
every time.
I've done the layour using IB and set the CustomView type appropriately; the
current version of the .h file has been parsed as well. Is the NULL value
trying to tell me something?

Hi all.
I have the need to record some CD-ROMs from my intel based
NS 3.3 box.
I dug of the source for mkisofs by Eric Youngblood and gave
compiling it a quick shot.
However, it seems to want some header files that I have
no idea about. (Not that I have any idea about any header
files, but...) The first one it pukes on is "sysmacros.h" in the
following bit of code:
#ifndef __QNX__
#include <sys/sysmacros.h>
...
Now, I'm not sure why this ifndef is being executed (QNX?) but
if I remove it it dies anyway, with an undefined type...
Are there any portmasters out there who have some idea
what might be involved in porting this thing? Should I give up?
(I know only a very little bit about C...)

I would like to get into programming etc., but am unsure
which operating system/language etc. to go with...
* What is the market share for NextStep?
* Could a person make a living developing for NextStep?
* Is it true that NextStep is a couple of years ahead of
something like NT or 95 ?
* Is NextStep going to fade away in the years to come,
or is it something a person could "stick with" (say five
or ten years from now).
* (If you are a consultant), what would be the going rate
for a Next programmer?
I may not have the proper names of some of the programs/languages
etc. down correctly, and am primarily interested in a broad overview.
I would like to develop a thread, or we could move to private email
if this is not the appropriate forum.

Subject: Problems with the write-method of the object "Storage"
Date: 11 Sep 1995 14:03:00 GMT
Organization: GMD, Sankt Augustin, Germany
Message-ID: <431fik$h9l@omega.gmd.de>
Hello NS-Programers!
My problem:
I have a structure called "Entry"
typedef struct _Entry {
char *name;
char *cname;
} Entry;
and a "storage"-object "Adressen" /*sorry, the source code is german */
Adressen = [Storage alloc];
[Adressen initCount:0 elementSize:512 description:"{**}"];
which should contain structures of type "Entry".
I put a structure in the stroage "Adressen" using
...
Entry AdrEntry;
....
AdrEntry.name = "Name";
AdrEntry.cname = "cName";
...
[Adressen insertElement:&AdrEntry at:i];
Problem: When I want to save the content of the storage "Adressen" in an
file using
NXTypedStream *tpdStream;
tpdStream = NXOpenTypedStreamForFile(myfilename, NX_WRITEONLY);
NXWriteObject(tpdStream, Adressen);
NXCloseTypedStream(tpdStream);
in the file appears only the first element of the storage AND some NULL
POINTERS (as many as other objects contained by the storage)
Is there a known problem with the "write"-method of the storage object?
First I thought, that the problem is, that I store only pointers to the
storage object "Adressen". But if I try to use
[Adressen insertElement:AdrEntry at:i]
(without the "&"), the I got a comiler-failure
incompatible type for argument 1 of `insertElement:at:'
Any ideas :-(((

Contact the maker of your P-90 motherboard and ask them. The call you used
normally consults values determined by the hardware manufacturer for the
particular system type in use. You'd probably get correct results if you
ran it on black hardware, and maybe even if you ran it on HP or Sun
machines.
However, I don't believe there's any way for the OS to determine which PC
motherboard and quartz clock you're using, so there's no way for the system
to give you a valid response.

I'm not altogether positive (and hoping someone else is and will tell me)
but it appears that 'const' in ANSI C (and ObjC) behaves differently from
the 'const' in C++. This may be compiler specific but that's what I'm
trying to find out.
I noticed that for 'const' in C++, the so-qualified names/variables were
allocated memory in the global space for the program, whereas the C
'const' could be allocated memory if the number was a value too big to be
included in the instruction itself (some kind of MOVE immediate or AND
immediate or whatever). You'd think that C++ would do the same thing but
my compiler always allocates memory for the number and references that.
Is this the right way to do things or should I tell the compiler vendor
they have a bug? Sorry for the non-ObjC'ness of the question.
thanks,
stephen

Organization: Institute of Molecular Biology and Biochemistry, SFU
Message-ID: <432fic$nif@morgoth.sfu.ca>
Hi. The application I am working on consists of a number of tasks
that a user has to get done, mostly data entry. You could imagine
the app as a inventory control system where the user adds
and deletes suppliers, customers, products, etc (the actual app is
unrelated but hard to explain in a short space). I am trying to
figure out what user interface paridigm is best for this kind of app.
Right now the way it works is each task is handled by a seperate
controller and a seperate .nib, all hooked into the main menu. The
user selects a task from the main menu, and up pops the appropriate
data entry screen.
Early on it was decided that we would allow the user to work on only
one task at a time, hence the data entry panels are brought up as modal,
forcing the user to close one task before opening another. I omit
the reasoning for this due to space, but I can explain in a follow
up if it helps.
Anyway, this "feels" strange when you actually run the thing. Really
what makes more sense to me is what Preferences.app does: one big
screen with a horizontal "menu" across the top, and a common view
that changes as you choose tasks.
Sooooo... The question is: how does one program this? I still want
to be able to arrange the various browsers and forms in this common
view with IB, as I do currently with the various data entry panels.
I am vaguely aware of the Palette available to create a "file folder look,"
like in the new IB that comes with EOF.
Any other insights on how I might present this kind of application to
the user would be very appreciated.
Thanks,
- Ken

Because the dictionary entries are organized internally (to support fast
access) based upon their keys (which are assumed to remain unchanged).
If dictionaries retained their keys instead of copying them, you could change
the key of an entry after it had been stored, thus breaking the dictionary
(table lookups could fail to find entries or return the wrong entries for
example).
More formally, key immutability is an invariant of the dictionary data
structure.
If you need to change a key, your only choice is to remove the entry and
reinsert it with the new key.
Without this restriction, the only possibible implementation for a dictionary
would be to use some sort of data structure with a linear (instead of
constant) access time. why?
The nice thing about NSStrings are that, since they are immutable, this copy
can be implemented as efficiently as retain. Thus you get the safety of a
reliable data structure and the efficiency of a hash table, without placing a
difficult burden upon the programmer.

I don't believe the language definitions for ANSI-C, Obj-C, or C++ mandate
whether storage has to be allocated for a const variable. So long as it does
not change the meaning of the program, the compiler is free to optimize local
variables in various ways. For example, this:
int fun(int x)
{
const int y = 1;
return (x + y);
}
...can be turned into...
int fun(int x)
{
return (x + 1);
}
...without changing the meaning of the program. There are issues with code
being arranged in "basic blocks" around "sequence points" for optimization and
debuggability considerations with regard to variable and/or dead code removal,
but I don't want to get too involved.
If you wish to guarantee that storage is never allocated and the 'variable' is
always used as an immediate constant, use a #define. If you wish to guarantee
that storage is always allocated, take the address of the variable via the "&"
operator, or use the "volatile" qualifier.

Well, what are you trying to do in which the distinction matters?

Oops. What I meant was that I was wondering why keeping the keys was
necessary, which is obvious (for instance to enumerate the keys). And if
you want to keep them around, you have to copy them, of course. You don't
need to copy or retain the keys only if you limit yourself to address
computation. Sorry for the bandwith.

I just checked and found it as

utar.gz
All the NeXT stuff seems to be gone at ftp.et.byu.edu (the primary site
for MiscKit). If all else fails, you can try
ftp://ftp.eecs.umich.edu/pub/nextmusic/
I keep a copy of MiscKit there because it has some sound objects.

The MiscKit stuff at BYU has been removed--as several folks
have already noticed. A new archive site has been found and
the items that were on ftp.et.byu.edu will be placed on the
new site as soon as possible. Note that the MiscKit mailing
list is also temporarily out of commission due to this
change.
When the ftp area and the mailing lists are again functional
I will send an announcement to comp.sys.next.announce that
details the changes. The affected mailing lists will also
be sent a message describing the change. The affected lists
are: misckit, miscdoc, miscstring, gamekit, nextinterpreter,
and na2sig. (The gamekit and na2sig may not be reinstated
right away since they have been dead for a while.)
Until this is fixed, used the orst or peanuts ftp sites to
get at the current release of the MiscKit (1.6.1). The next
MiscKit release--1.6.2--will happen when the new ftp site
is fully operational, for those who care.
If you have any further questions, feel free to contact me
as necessary. Sorry for any inconvenience!
Later,

Hi,
while writing a loadable kernel server, I came across this
one. I don't know if this is really a bug, but I suppose...
When forking a thread in a loadable kernel server using
kernel_thread the newly created thread does not have a default
reply port. If the new thread subsequently issues a mach
call, the reply port gets created by a call to mig_get_reply_port.
This is correct as the new thread needs its own communication
backchannel as it might be that serveral threads issue interleaved
msg_rpc's.
If the thread terminates itself later, this newly allocated
port stays allocated. If you do this about 22000 times, all
ports are in use and the kernel panics.
I suspect the problem lies in the code which is responsible
for terminating a thread. It should release the reply port
but doesn't. I tried to get rid of the reply port in the
thread itself, but as port_deallocate is a mach rpc call, it
needs the reply port until it returns - so a call to
port_deallocate results in a kernel panic as well. What is
the right way around this obstacle (besides forking a thread
only for deallocating all unneeded reply ports on behalf of
the soon to be terminated threads)?
Anyone dare to comment?

Sorry for following up on my own post, but I forgot to
mention another curious fact:
In <mach/mach_user_internal.h> there's the following define
#define thread_terminate thread_terminate_EXTERNAL
thread_terminate_EXTERNAL does not exist in the kernel, but
the kernel server linker does not complain about this symbol
not being found on load of the kernel server and the kernel
panics when I try to do the call.
If I undef thread_terminate before I use it, it works as
advertised. Hmmm....

Why, add a category to NSObject of course :-)
e.g.:
#import <objc/objc-runtime.h>
@implementation NSObject (YetAnotherHybridWorldCompatibilityFix)
- (BOOL)isKindOfClassNamed:(const char *)aClassName
{
return [self isKindOfClass:objc_getClass(aClassName)];
}
- (BOOL)isMemberOfClassNamed:(const char *)aClassName
{
return [self isMemberOfClass:objc_getClass(aClassName)];
}
@end
should do the trick.

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

[from the document ftp://ftp.next.com/pub/NeXTanswers/1000_Help]
Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.
USING NEXTANSWERS BY FAX
To use NeXTanswers by fax, call (415) 780-3990 from a touch-tone phone and
follow the instructions. You'll be asked for your fax number, a number to

And a hash-table cannot be built without keeping the keys, because those
are needed to solve hash-collisions.
I am personally not sure that NSDictionary copying keys in all the cases
is a GoodThing, but this is another story... :-)

I'm sure he means the OpenGL work-alike called Mesa written by Brian Paul.
Given the existence of an X library on NEXTSTEP, I see no reason why
it wouldn't work fine. I'm actually planning on giving it a try when
I get the latest version of Cub'X-Window.

Another option is VOGL, which does compile for NextStep (at least,
it did when I last tried it a couple of years ago), and has a postscript
output option.

Mesa is another implementation similar to OpenGL. See:
http://www.ssec.wisc.edu/~brianp/Mesa.html
I does not look like it has been ported to NextStep, although
(obviously) it would probably work with one of the X servers running atop
NextStep.

Hi all,
Has anyone built a multi-architecture binary on NS/FIP 3.3.
I think I have left something out because I have tried and I get a
mismatch from the linker relating to cputype on /usr/lib/libIndexing.
Sure the precompiled headers fail but the system seems to cope. It's the
linker that doesn't seem to cope.
Are there different libraries used for multi-architecture binaries?
Do I just tick every architecture in Project Builder that I want to build
and it does the rest or must I do something by hand?
I am pretty sure I installed everything necessary for Multi-Architecture
Binaries but are there any gotchas people can tell me about?
I have tried searching for 'MAB' and 'architecture' in the Librarian but
to no avail.
Any assistance appreciated.
Cheers,
Greg Shaw.

There's an article in one of the OpenStep Journal's on some
of the changes with OpenStep, and I believe a new way of
handling defaults is one of them. I don't believe it has
any connection to using netinfo, but I'm too tired right now
to track down the article and reread it. Maybe it does.
Okay, I'll track it down a little. It's mentioned on pages
13 and 14 of Volume 1, Issue 1 of OpenStep Journal.

The OpenStep defaults strategy, as I remember it, was supposed
to address these kinds of issues.

I don't think the new defaults strategy directly addresses these
screen-size issues, but it looks like it would be flexible enough
to handle them. Application writers would have to be consistent
(across apps) on what defaults database would be the one(s) for
resolution-dependent defaults.
> Now wouldn't it be fine, if any application is aware of the

> defaultbase entries?
For the applications that I write, I do that. So, for instance,
my mCD application has written defaults of
mCD ControlFrame-1024x768 "738 153 219 446 0 0 956 768 "
mCD ControlFrame-1408x1024 "1119 292 216 733 0 0 1340 1024 "
mCD ControlFrame-1280x1024 "997 305 215 592 0 0 1212 1024 "
mCD ControlFrame-1152x864 "869 149 220 502 0 0 1084 864 "
for when I'm running it on my NS/Intel box. Hmm. I think
there's supposed to be a "ControlFrame" there too (one that
doesn't include the resolution), so that the *default* for
some new screen resolution is based on the last thing I've
set for the location on some other screen resolution.
The next trick is to do something special for systems with multiple
monitors on them. I do that for CheckMail, and I think I do that
for mCD too (by having another distinctive name for the default
when multiple screens are active). I'd have to look at the source
code to remember what I do in that case...
Now if you really wanted to do the "perfect thing", you'd have to
answer the question "which monitor does the user really want when
saving a default for multiple monitors?". For instance, I might
position my mCD and CheckMail windows to be on the *greyscale*
monitor, no matter what combination of monitors I might have on
different machines. Answering this question gets tricky...
Of course, I only do this for window locations. I didn't think
to do this for things like font sizes.

Something like this would be nicer than what I'm doing. OpenStep
does allow for searching thru multiple defaults databases, and for
defining new databases in addition to the ones that NeXT plans on
using by default (which is to say, their default list of defaults
databases).
The article isn't detailed enough to say how this list of defaults
databases would be coordinated between multiple applications.

Hi!
We're developping some vertical applications that use the DBKit heavily.
One of these applications need to access a table in a database regularly.
We discovered that each fetch to the database result in an increase in the
memory used by the application. We did a test application that only do a
fetch every minute. The result is an increase of ~100K after every fetch.
The number of records in the table is always the same, and we don't modify
any record, just browsing them. Here is the method that do the fetch:
- fetchLesMesures:sender
{
/* Assume testsDBModule is a DBModule, for the entity 'Tests', */
/* loaded from the nib file. */
/* Table 'Tests' has a one to many relation to table 'Measures' */
id testsFetchGroup = [testsDBModule rootFetchGroup];
unsigned int c, nombreMesures;
nombreMesures = 0;
[testsDBModule fetchAllRecords:self];
for (c = 0; c < [testsFetchGroup recordCount]; c++)
{
/* To activate the related records in table 'Measures' */
[testsFetchGroup setCurrentRecord:c];
}
return self;
}
Any idea, comment, info, pointer gladly accepted!
-Laurent.

FX-80 as a NEXTSTEP printing device. And it works just fine. But I
encountered this problem while doing it:
"epsonfilt < blah.ps > /dev/pp0" doesn't work; part of the data
gets to the printer, but part of it is lost, so the image works okay
for the first line or so but then is completely screwed up.
But when I create a printer entry, and give it "epsonfilt" for the
filter program and /dev/pp0 for the device, it works without flaw
every time.
What does the print subsystem know about sending things to /dev/pp0
that I don't?
Thanks in advance ...

DBKit leaks memory. There's little (if anything) you can do to
prevent it. And you can't free any DBModule without causing memory
problems that will crash your app. All of this should be strong incentive
to migrate to EOF which will be supported in the future unlike DBKit.

Hi Jeremy,
We have also written an RTF reader/writer, which we use in a word processor
application we are writing, but I have not seen a \nextcolortbl directive
generated by Text.
However, I did a scan on our disk for that directive and found it in some
files generated by a demo version of an accounts package called SUMERIS.
The files that the directive appeared in are not RTF files, although they do
contain blocks of rtf definitions.
A valid RTF reader can ignore the \nextcolortbl and \nextcolor1 directives,
but the string of characters following \nextcolor1 will appear in the current
destination as plain text.
Any RTF writer produced after 1989 should make use of the \# directive
definition that instructs RTF readers to ignore the current group if it doesn't
recognise the directive. Hence a \#nextcolortbl would in the above case allow
all RTF readers not to display the garbage following \nextcolor1.
As RTF is an extensible language, your reader can't be expected to recognise
all RTF directives. The SUMERIS files contain valid \colortbl definitions that
all RTF readers can recognise.
The only other next specific directives that I have seen Text generate are
\smartcopy which is used to indicate whether the selection was made by double
clicking or not; and \NeXTGraphic, \NeXTHelpMarker etc that are used for
embedded graphics in RTFD files.
Regards,
Paul Heffernan.

: Mesa is another implementation similar to OpenGL. See:

There's a project working on a GNUstep 3DKit to replace NeXT's 3DKit
(which will be obviously withdrawn in the future). It is planned to
port Mesa to NEXTSTEP, and replace Renderman with OpenGL for GNUstep 3DKit
(http://wwwcip.informatik.uni-erlangen.de/user/tsengel/G3DKit/G3DKit.html).
The Mesa port should be quite straighforward.

These are generated for "special" colors (colors which are richer than
just RGB). These include CMYK and Pantone. The RGB version of the color
is still written out, allowing non-NEXTSTEP readers to get a close enough

Hi everyone. I'm not sure whether I'm missing the point by pondering about
this ... so if I am someone please tell me.
I am trying to display a pixel on the screen. By that I mean that, given a
coordinate (x,y), I want to be able to light up the pixel in a view that
is nearest to that point. Some sample uses I can think of are to process
images, ray tracing, rendering, etc... I realize that NXImage can handle
images, but putting a pixel on a screen is what I'm trying to do right
now.
Is this unrealistic under NeXTSTEP ? If so .. how are the above things
done under NeXT ? How does, for example, id Software's DOOM manage to draw
in a window ?
Thanks for any help. Please forward any replies to my email address.

You could get the source code for Alexandra.app and modify it so that the

No such program exists; natural language translation is a very tough
problem that does not have very good solutions available. Even attempts to
move from closely related languages, such as from French to Italian, say,
simply don't work that well (especially for technical material).

The problem seems to be that these non-standard directives are not
proceeded by \*, which, according to the RTF specification, should be used
to signal a directive that should be ignored (including any text
associated with the directive) if the directive is not recognized by the
RTF reader. According to this spec, the reader should go ahead and insert
the text for unrecognized directives that DO NOT use \*. Here is a sample
of the RTF generated by the Text object running under NS 3.2:
...{\colortbl;\red255\green255\blue255;\red0\green123\blue185;\red0\green0\
blue0;}
{\nextcolortbl{\nextcolor1
040b73747265616d747970656481a20384016341840173fe93fe}
{\nextcolor2
040b73747265616d747970656481a203840163c4840373737300817b7b81b8b984012584067
f411b312d33}
}
\cb1\pard...
Since there is no \* preceding \nextcolortbl or \nextcolor1, etc, that
would mean the following text would be inserted into the output:
040b73747265616d747970656481a20384016341840173fe93fe040b73747265616d7479706

Somehow I do not think that this is the intended behavior.
Here is the text from the Microsoft RTF spec to which I have been
referring:
---
Certain groups, referred to as "destinations," mark the beginning of a
collection of related text. An example of this is the \footnote group,
where the footnote text follows the control word. Destinations added
after the RTF specification published in the March 1987 Microsoft Systems
Journal may be preceded by the control symbol \*. This control symbol
identifies destinations whose related text should be ignored if the RTF
reader does not recognize the destination. RTF writers should follow this
convention when adding new control word. Destinations whose related text
should be inserted into the document even if the destination is not
recognized should not use \*. In this chapter, all destinations that use
\* will be shown with \* as part of the control word.

Subject: 3DKit, N3DShape, and N3DShapeName
Date: 19 Sep 1995 03:31:45 GMT
Organization: Purdue University
Message-ID: <43ldj1$rk8@mozo.cc.purdue.edu>
Anybody know what 'id' is in this struct? I don't understand the comment
about "encoded to 6 non-0 bytes". What is being encoded and how is it
encoded? The struct is defined in N3DShape.h in the 3DKit.
typedef struct {
char id[6]; /* self, encoded to 6 non-0 bytes */
char name; /* optional visible name */
} N3DShapeName;
The reason I ask is that N3DShape doesn't seem to properly unarchive the
member data
N3DShapeName *shapeName;
That is, shapeName is nil after a shape is unarchived with the standard
N3DShape method 'read:'. (But shapeName does seem to have a valid value
when my N3DShape is created with 'init'.)
If I override the read method and artificially create a shapeName struct,
then no problem. But I don't know whether shapeName has to have a valid
value in order for the N3DShape to behave properly.
Any help would be appreciated.
Thanks,
Greg

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Greetings,
I got a question regarding the object naming under PDO. Back to 3.0, when
DO was first introduced, NXConnection's connectToName: used the mach name
server to resolve the registered object name, which bore a limitation that
the naming could not cross the subnet boundaries. My question is that does
PDO resolves this problem? If so, suppose that I am using DO on NextStep to
talk to objects running on both NextStep and non-NextStep platforms (like
HP-UX, or Solaris), both in the same subnet and across WAN, do I need to
specify that which name server to use, MACH's network name server or PDO's?
and in what level do I have to concern myself with the name conflicts?
Thanks.

Subject: Crash when dragging an image

Hi,
I found a problem which causes crash under both 3.2 and 3.3 when dragging
an image. The reason for this problem is that when the drag listener is
created, it sets the instance variable _delegate2 to be the delegate of
NXApp, which is the delegate of the drag listener created. The problem is
that when later you set NXApp's delegate to another object and free the
first one, the drag listener won't reset its _delegate2 instance variable,
so it crashes with the error "message sent to a freed object" when an image
is dragged.
Ever since I found the cause of the problem, I tried to work around the
problem by setting NXApp's delegate to be nil at the possible places where
the drag listener might be created (like the first time an open panel is
created, or the first time the document which is opened by this application
is double-clicked) (BTW, I need this delegate of NXApp for the first responder
thing). It resolved less crashes, but this _delegate2 of drag listener still
causes problem from time to time. I called NeXT technical support, they
acknowledged it is a bug, the only thing they can do is to submit a full
bug report, but I have to pay like $150 an hour to talk to some guy to find
a work around, which I find it hard to swallow to pay for their bug.
Has anyone experienced the same problem? If you have, how did you solve it?
Thanks.

Summary: weird stuff
Hi, I'm having a real problem with (I belive) some options
code for a program I'm trying to port to NS. This isn't one
of those blatently obvious things, as the code is in C, and
it compiled fine on a whole slew of other platforms, but
not on NEXTSTEP. (This is the story of my life I think... grumble)
Anyway, I am not quite good enough to figure out what the hell
is wrong with the code, so I'm asking for some help with it.
Here's the deal:
cmkdir -3 foobar
Segmentation fault
Ok, from gdb:
iStarting program: /Users/tfs/tmp/cfs/cmkdir -3 foobar
Program generated(1): Memory access exception on address 0x3f7f2b8 (invalid address).
Reading in symbols for cmkdir.c...done.
0x24cc in main (argc=3, argv=0x3fffb30) at cmkdir.c:39
39 {
(gdb)
From the source. Ok, one thing here, I can't post much beyond this file
because if I did, I'd be exporting a cryptosystem. This file doesn't
actually do any encryption, only sets things up a bit, I'm fairly
sure it's not a problem. (Of course if you've got a sphincter that
turns pencil lead to coal because you're so uptight, even mentioning
crypto is a bad thing. I on the other hand prefer security & privacy,
and want to get this damned thing to work. As you can guess, I live
in the USA, which is more intrested in listening to it's citizens
than safguarding thier privacy.) ranting aside, I really can not
figure out why the hell this is such a problem. Then again, I do
spend literaly hours often working on other programs that work
fine on 8 diffrent Unixes but not on these puppies...
ANY help I could get on this would earn my undying thanks.
This is part of Matt Blazes cryptographic file system program,
if you're in the US you can get it from him, if you're outside,
you can probably get it, but *I* don't know where for the record. :/
(allthough I've heard rumors if you really want it.) If you get intrested
and want to fix it keep me posted is all i ask.. My "working"
version is old and crufty and has bugs that this version fixes.

You also need:

I'm having a problem getting an application that works correctly by
clicking on the app icon and then opening a file, to start correctly
when I dbl-click on the a file of the type recognized by the app.
I have a subclass of Application where I have acceptsAnotherFile

as well as:
- (int)openFile:(const char *)filename ok:(int *)flag
The File's Owner specifies that the sublass is the Owner. Another
class has appDidInit in it and it is the delegate of the File's Owner.
Now when I double click on the files icon, The app launches, but I
never see appDidInit, openFile:ok: getting messaged. AND the data
doesn't get read into the app as it should.
What pieces are the minimum necessary and where do they go in order for
dbl-clicking on the file's icon to cause the app to launch AND the
filename to be presented for reading?

You can't - the other (non-shared) part of the libary is only
distributed to specific developers who demonstrate that they need it,
and will use it responsibly.
I've used it, and agree with this policy - its not that Interceptor is
hard to program, but it is fiddley. Releasing it publically would
encourage its use, and produce a large number of hardware dependant
programs.
You have to write you code to handle all possible depths and formats of
display hardware, and for most applications its simply not worth the
trouble.You would also need the resources to test an interceptor program
on each of the different screen types - it doesn't "just work" in the
way most NeXT stuff does.
(it also has a couple of bugs that are driving me nuts!!)

Cc: samschap@merle.acns.nwu.edu
# I'm trying to build runtime access to arbitrary Objective-C

It is a lot easier than constructing the stack frames by hand...
basically, you need to:
1. check to make sure the target object/class responds to the selector
(-respondsTo:)
2. use class_getInstanceMethod() or class_getClassMethod() to obtain the
runtime's information in regards to argument and return types
3. use method_getNumberOfArguments() to determine the number of arguments
4. use method_getSizeOfArguments() to determine the frame size
5. use marg_malloc() to allocate a stack frame
6. iterate across the arguments, use method_getArgumentInfo() to obtain arg
type and marg_setValue to set the value of a particular argument within the
list
7. repeat 6 for all arguments
8. call objc_msgSendV()
9. convert return type
---
The above will take care of a large percentage of the API encountered
within ObjectiveC, but it is not a generic solution. For that matter, it is
impossible to build a generic solution using JUST the information found in
the Objective-C runtime.
Specifically:
- how do you tell the difference between a BOOL and a CHAR?
- how do you deal with a (void *), such as HashTable, that may mean any of
a number of things?
- how do you tell if the address or the contents of a (char *) is the
significant piece of information?
- structures passed by value? (or, parsing structures passed by reference)?
- how do you deal with cases where some idiot developer is misusing an
object (such as by storing (char *)s in a List)?
[if i offended anyone with that last statement-- you deserve to be
offended... as always, my opinions are opinions and you are welcome to
present evidence to the contrary... in this case, you'll lose (but not
because my mind is closed!)]
Also, there is some evidence that the various marg_get and marg_set macros
do not work correctly for certain data types on the HP. Since I have an HP
and I'm likely to be working with a generic ObjC to Python interface, it is
likely that I will run across some of these bugs and will post if I do....

Message-ID: <43n8ht$22f@stc06.ctd.ornl.gov>
I've installed MiscKit and attempting to use the MiscDragViews.palette
I place the palette in my palettes, drag the text well to a window,
make a subclass of object called DragController and make it the
delegate of the file's owner. I add a method to the DragController
called dropped:sender and have it do the following:
- dropped:sender
{
[theText setStringValue:[theWell filename]];
return self;
}
Now theText is the id of a textfield in the window and theWell is the
id of the Drag Well (both connected via IB).
I connect the target of the DragWell to dropped.
I added the -L/LocalDeveloper/Libraries etc to the Makefile.preamble
and it compiles and loads. For some reason it worked fine also FOR a
WHILE! I then changed the Well to NOT allow Source Dragging and did a
remake and BOOM, I get
Program generated(1): Memory access exception on address 0xbead0389
(invalid address).
0x50069cc in objc_msgSend ()
when I try to drag into the well. My code is not called here, this is
happening all in the Drag stuff.
I changed back via IB to allow Source Dragging and recompiled, etc.
Now I still get the message and can't locate why.
Any ideas? How should one set this up to experiment with it?

Hi,
Should ROWIDs be designated DBModeler primary keys? The ROWIDs dont show
up as a property of the entity under DBModeler, so how should you access it?
Does using ROWIDs for relationship keys result in zippier joins?
Any insights appreciated. Thanks.

In my own 3DKit app I set and read a shape's name with the N3DShape
"setShapeName:" and "shapeName" methods which take and return char *. My
app explicitly creates name-strings for each shape it makes.
I've never accessed or modified the N3DShapeName struct but have nevertheless
created, archived and unarchived named shapes successfully using the
above two methods. My app's lack of knowledge about the state of the
N3DShapeName struct doesn't seem to be relevant to the correct functioning of
the program.
I'm not sure exactly where my shape names are stored if not in the
N3DShapeName structure. My guess is that the "id" component is the
instantiated shape object's id value encoded into 6 character values.
The N3DShapeName struct is described in the 3DKit's Types & Constants
document as representing "The name and id of the shape as character
strings (used for picking shapes)".

The tool build option for PB uses a crippled make facility. For example, it
doesn't support Subprojects, etc...
To build a non Application application, just use the Application build
from PB, but turn off the generate main on save feature. That way you get
all the goodies of an app build without it clobbering your main.c file
that you'll right yourself to get your NXConnection run loop going, among
other things. Leave the app wrapper in tact -- it's a good place to tuck
those bundles you'll like to drop into your server.

I think, NXImage does not use representations that are deeper than the
window server's deepest window. One solution to get a 24 bit image is to
open an offscreen-window, force a window-depth promotion, and then recreate
an image rep out of this window. You should try something like that:
NXBitmapImageRep *image24Bit;
Window *imageCache;
View *cacheView;
NXRect imageRect;
// sourceImage is your own image
[sourceImage getSize: &imageRect.size];
imageRect.origin.x = 0.0; imageRect.origin.y = 0.0;
imageCache = [[Window allocFromZone: [self zone]]
initContent: &imageRect
style: NX_PLAINSTYLE
backing: NX_RETAINED
buttonMask: 0
defer: NO];
// trick: we draw a red pixel to force a window-depth promotion :-)
[imageCache setDepthLimit: NX_TwentyFourBitRGBDepth];
cacheView = [imageCache contentView];
[cacheView lockFocus];
PSsetrgbcolor(1.0, 0.0, 0.0);
PSmoveto(0.0, 0.0);
PSlineto(0.0, 0.0);
PSstroke();
// no draw your own image in the window. If it is an NXImage, use:
[sourceImage composite: NX_SOVER toPoint: &imageRect.origin];
// if it is an NXBitmapImageRep, use:
// [sourceImage draw];
// grab the image as 24 bit representation
image24Bit = [[NXBitmapImageRep alloc]
initData: NULL fromRect: &imageRect];
[cacheView unlockFocus];
[imageCache free];
// this should create the 24 bit TIFF file
stream = NXOpenMemory(NULL, 0, NX_WRITEONLY);
[image24Bit writeTIFF: stream];
NXSaveToFile(stream, someFilename);
NXCloseMemory(stream, NX_FREEBUFFER);
[image24Bit free];
I hope it works...

You have to use the option -posix when compiling and linking in order to be

how can i determine a sensible margin to leave beyond the boundaries of

i am programming under NeXTStep, which provides a default set of

any input appreciated (but please email if possible because our news

Kieran,
Thank you *very* much for the reply! Since it works for you, I concluded
that it must be something in my code. Sure enough, the problem was mine.
For one of my N3DShape subclasses, I had overridden the awake method as
- awake
{
return self;
}
instead of
- awake
{
return [super awake];
}
It seems that the N3DShapeName struct is allocated and initialized in the
N3DShape awake method. Since I was circumventing the super's awake
method, I wasn't getting the structure.

I don't know how they are storing the shape name in a 6-byte char string,
but when I use setShapeName as you suggested, the name does indeed seem to
be stored in 'shapeName->id', starting at byte 7. I don't understand
that, but as long as it works, I'm content.
Thanks again, Kieran!

Subject: howto do "writeTIFF" with 24bit pictures
Date: 18 Sep 1995 01:05:25 GMT
Organization: Nanyang Technological University
Message-ID: <43igkl$2r7@ntuix.ntu.ac.sg>
Hi,
I have a problem with creating TIFF files with different bit-depths from
those the system it is running on. So as an example, when I want to create
a 24-bit imageRep with a picture that is created by my application, I do
the following (lots of code left out):
imageRep = [[NXBitmapImageRep alloc]
initData:NULL
pixelsWide:width pixelsHigh:height
bitsPerSample:8 samplesPerPixel:3
hasAlpha:NO isPlanar:NO colorSpace:NX_RGBColorSpace
bytesPerRow:3*width bitsPerPixel:24];
Then I create the picture with:
dataArray = [imageRep data];
fillBitmap (dataArray); /* my own procedure */
image = [[NXImage alloc] initSize:&bounds.size];
[image useRepresentation:imageRep];
So far so good, I can display the picture in a View, but now I want to
save the picture in a TIFF file:
stream = NXOpenFile (fd, NX_WRITEONLY);
[image writeTIFF:stream allRepresentations:YES];
This creates the TIFF file with the picture, but it uses the screen-type
for bitsPerSample, resulting in a 12-bit TIFF file instead of a 24-bit
one. If I use:
[image writeTIFF:stream];
the same happens.
WHAT AM I DOING WRONG ????

Hi all,
We've just received a Tektronix 340 colour printer. We have the following
problem: When we print anything to it, our whites don't come out white! We
see a small amount of cyan ink on the 'white' areas. When I send
PostScript direct to the printer with a 1.0 setgray it does appear white,
but when I print something from NS, I get the small amount of cyan.
I assume there is something in the NS encoding that transforms colours to
something other than white - what can I do to fix this! I can't use
documents where white areas are speckled!

Distribution: world
Message-ID: <43rmg3$9lu@stc06.ctd.ornl.gov>
I've set up a very simple Demo application to show how
the MiscDragViews.palette can be used to create a window
wherein there is an icon well and a ScrollView with a matrix of
textfields for filenames. As files are dragged and dropped into the
icon well, the filenames appear in the scrolling matrix of textfields
in the ScrollView. The point is so that then, by clicking on the
filename in the ScrollView the proper icon will appear back in the well
and then by double clicking on the icon, that document will be opened
to read.
Everything works, except the cursor is always indicating that the
ScrollView (or something in it) is editable and the clicks are not
received. I've enabled everything I could find so that it could
receive mouse clicks, and made everything uneditable and unselectable,
but I still get the edit cursor over the ScrollView. Is there a
content view or documentview that is causing this behavior?
Thanks for any information.

I'm not sure why your question was posted to comp.sys.next.programmer and
not comp.sys.next.sysadmin but...
The problem is that you have a CMYK (Cyan, Magenta, Yellow, Black) printer and
your PPD is probably configured incorrectly or has a bug. Remember that CMY=K
so instead of using the black ink, NS is probably using the CMY inks in
combination to produce black. Since white is 1-CMY, you are probably getting
some sort of error. Look at your PPD (PostScript Printer Definition) file
and/or try setting the color directly using 0.0 0.0 0.0 0.0 setcmykcolor. The
PPD is located in /NextLibrary/PrinterTypes/English.lproj

Actually you can do
[image setCacheDepthBounded:NO]
to cause an instance of NXImage to use caches that are not bounded to the

You are using NXImage. Use NXBitmapImageRep instead and things

look through its representation list for the Bitmap.

It may be due to a similar problem we had with an early HP LaserJet
4M/PS with density plot that uses shades of grays (it may still be
there). White was not coming out as pure white. It may have to
do with some mismatch of Calibrated Color space in PS level-2. Try
the following calib chart, and try disabling level-2 flag in the
code with line:
% /_NXLevel2 false __NXdef % This, when enabled, forces PS Level-1
I don't know what you should do specifically for your case, but I
had to hack /usr/lib/NextStep/printPackage.ps and put some code to
fix the HP LJ problem (to make direct printing from various apps come
out right via a /DecodeLMN entry). I can e-mail or post a diff if you want
it.

Just curious: when I use a Text object and load it using
[textObj readText:stream];
it could takes literal years for it to load a big file with long
lines (no cr). Now if I use Edit.app to load just the same file
it works much faster.
I have found that setting the Text object to no wraping using
[textObj setNoWrap];
is speeding the operation up for the price that sometimes, if a
line is too long the Text objects just goes to never-never land...
(Bus error)
So what is Edit.app doing differently? I guess it is using
the same (b&b (big&bad)) Text object as everyone else, or?
Any ideas?

My problem with the Tektronix printer is solved.
For those interested, NEXTSTEP is clever with colour rendering. When you
print something, it attempts to make what comes out the printer look at
close to what is on screen as possible (logical, right). We'll, on-screen
white is actually a little blue compared to paper white based on the
white-points NeXT and Tektronix uses. So, sensibly enough, the printer
tries to print the white with a little blue. The amount is usually so
small that printers that use conventional half-toning can't produce that
amount of cyan/magenta. For better or worse the Tektronix 340 uses Floyd
Steinberg random dot ditheing rather than angled screens The result looks
great, but it also allows it to reproduce the very small amount of blue by
printing fairly widely spaced dots of cyan and magenta.....
OK, so what to do. After comment from Marcel Weiher
<marcel@spock.system.de> I had a closer look at the PostScript sent to the
printer. It includes the new operators nxsetgray and nxsetrgbcolor. These
apply a transformation to the base colour into the calibrated colour
system that NeXT uses.
The solution (after some hours of RTFMing, is to do a
dwrite GLOBAL NXUseCalibratedColor NO. This allows the printer itself to
do the colour calibration (since it provides assorted simulations
including display, process printing, SWOp and others).
This default only affects printing since display to the screen is done
using device colour for speed.
All in all, logical enough, but a bit startling when you see it!

^^^^^^^^^^
I forgot to mention in my earlier post on the topic that this is the most
artful synonym for "bonehead bug" I have ever seen. I thought the whole
point of regression testing was to make sure you _didn't_ break old stuff
when you add new features.

Oh, very nice. "We screwed up the debugger in a way that makes it almost
completely unusable, but you have to pay even more money to get back to
the same degree of functionality you had before you bought the upgrade."
For new interim functionality, I'm willing to pay Premium Support prices.
I'll even pay for the new-and-improved lookupd, although NeXT had plenty
of opportunities to fix that in time for 3.3, too. But I will NOT pay for
patches to fix an upgrade that BROKE fundamental tools which were working
in every prior release.
This is unconscionable. Is it any wonder that we brave remaining souls
grow lonelier by the day? "Please bend over just a _little_ farther, Mr.
Anderson, I think I can fit one more finger in." What's to stop NeXT from
INTENTIONALLY breaking old stuff in new releases, so there is NO CHOICE
but to get Premium Support to keep your system running?
Word to the wise in RWC: When you barely have any friends left, it
doesn't pay to p*** off those who continue to stand by you. This might
be a good time to consider the expectations of those 1000's of eager
suckers over in WindowsLand who will come to visit OpenStepLand, then
flee when they learn what constitutes "product support" around here.
You only get one chance to lose those folks, because they have other
choices. Why not start practicing good customer service now? Thanks!

I'd like to know what is necessary to be able to set break points on
code loaded from bundles when attaching to a process in gdb.
Imagine you were debugging an app that was launched from the workspace
and you fired up gdb and attached to the app. Is there anything
special that has to be in place to allow you to set and break on
breakpoints in gdb? Currently when I've done this I can set the
breakpoints no problem but they will _not_ break.
I don't think this is related to future-break as I said I can set the
breakpoints after I know the code is loaded they just don't break.
I stress that running that app within gdb rather than attaching
results in breaking properly.

I have a project which requires that my NeXT (NeXTstation, NeXTStep 3.2)

brand new to NeXT programming, but it looks like this has to be done with
a loadable kernal module. My system doesn't seem to have the source for
any of the modules that are already there, so I have nothing to use as an
example to work on writing one. Can anyone point me toward some source
for this sort of thing, or maybe someone who's already written a module
like this?

We experienced the same problem. As a result the Objective C compiler
couldn't compile the RTF source. Obviously the preprocessor didn't know
that special phrase either (and didn't filter it out). The same goes for
/NextDeveloper/Demos/FileMerge.app/convertRichTextToAscii, which we use
sometimes to convert our RTF source files back to Ascii when needed.
This began happening now and then when we started to mark some comments
with a special color. Below you find a short RTF document. If you copy the
font (and color) of the comment line into another RTF file (using Copy Font
/ Paste Font aka Cmd-3 and Cmd-4), the bogus directive will appear. But, if
you try to copy the color only (with Edit's Color panel: grab the color
with the magnifying glass, mark the text to become colored, drag the color
from the panel's well), this will not happen.
That's all I know so far. I sent a bug report to NeXT, because the C
preprocessor can't handle these files (though generated with Edit), but
received only the usual automatic registration reply yet (log number
73303).
Now we just remove these two lines with vi when they appear, and that's it.
The color of the comment line doesn't seem to change after that operation.
Maybe this kind of a hack could work for you, too. We didn't encounter any
side effects so far.

I'm just wondering if anyone out there has added anything to MiscTabMatrix.
More specifically I was thinking of adding a transparent background, and
the ability to display the tabs on the left or right side (with the text

I just didn't want to duplicate someone else's efforts, but if no one gets

>Really? Thus, a MutableSpecialString should contain two strings? --Tiggr
Well, no. In C++ one would use virtual inheritance at the first level,
thus guaranteeing that any subclasses only had ONE String part. For
example:
class String { /* string stuff here */ };
class MutableString : public virtual String { /* MutableString stuff here */ };
class SpecialString : public virtual String { /* SpecialString stuff here */ };
class MutableSpecialString : public MutableString, public SpecialString
{
};
This hierarchy guarantees that the MutableString & SpecialString parts
of MutableSpecialString SHARE a common String part.
Thus, the problem you bring up with MI can be solved with this language
"feature". However, there are more problems with it, such as the fact
that there must be a priori anticipation of the fact that somebody MIGHT
multiply-inherit from one of the subclasses of String and the virtual
must go there. There are, of course, other problems.
I make my living doing C++, but it's far too "carved in stone" to be the
nirvana that everyone seems to think it is. I wish ObjC++ would catch on,
so we could use the best features of each language.

Well, I just programmed this (the TIFF part) without any problems. I
just use an NXImage, and I were able to set it with or without alpha
with no problem what-soever. You only must be careful, that the
the output-ed TIFF is not limited to 4-bits color (or 2-bits gray).
Use [image setCacheDepthBounded:NO] to prevent that.
If you want some example-code (I'm now not at my NeXT), send me

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>

i received several useful replies (which i'm not posting because
forgot to mention that i'd summarise to the net)
the best solution was to use the PPD file for the
printer in question, which contains a field *ImageableArea
containing the printable rectangle for that printer.
luckily NeXT provide an object interface to PPD files
on their system (only from release 3.3 though, i think)
my final code looks like :
void get_paper_rect(NXRect *prect)
{
id printinfo = [NXApp printInfo];
id pr = [printinfo printer];
if (pr)
{
*prect = [pr imageRectForPaper:[printinfo paperType]];
/* returns zero width if can't find image rect */
if (prect->size.width <= 0.001)
pr = nil;
}
if (pr == nil) /* if no printer, or couldn't get image rect */
{
NXCoord l, r, t, b;
*prect = *[printinfo paperRect];
[printinfo getMarginLeft:&l right:&r top:&t bottom:&b];
prect->size.width -= l + r;
prect->size.height -= t + b;
prect->origin.x = l;
prect->origin.y = b;
}
return self;
}
obviously this is only valid under NeXTStep!

fact, you will find that even with the NeXT compiler, a constant may be
allocated storage on one architecture but not another.
In answer to the larger question, 'const' does have a different meaning under
C++ (where the qualifier originated) than under C (which adopted a less strict
meaning for the qualifier). For example, the default linkage is different.

More generally, compilers can do anything internally so long as they do not
"change the meaning of the program."

Even this may not be enough in some instances with the NeXT compiler (e.g.,
floating point constants for some architectures and structures). For integer
constants, you may also wish to consider using an enum (handier for debugging).

Taking the address works in most situations. Another alternative is explicitly
declaring the variable "extern".

There are many valid TIFF files NeXT's libraries do not read properly. In
fact, as I recall, the TIFF standard admits that it is so complicated that
probably no reader has ever been written that will read all TIFF files. NeXT
does not fully document which flavors of TIFF files they read, and the
acceptable versions depend upon exactly which OS release you are running.
As for a way around this, the easiest way is probably to write your own viewer.
You may also be able to find converters to change your file to a 12 or 8-bit
TIFF, if that is acceptable.

For Pentiums and some 486 chips, the OS could query the chip for its ID
information and time its on-chip cycle counter. Access to the on-chip counter
is not prohibited by NEXTSTEP, so any programmer can compare it to the system
clock to find the chip speed and use the on-chip counter for profiling.

That's not generally correct. The system clock may be updated
continuously, as the manpage indicates. A quick purusual of an incoming
news feed which does millisecond-level timestamps shows that NEXTSTEP/Intel
updates the clock with greater resolution than (1 / HZ).

Yes, but that doesn't tell you the accuracy and resolution of the system
clock itself, which presumably was asked for the purposes of configuring an
XNTP time server.

To quote from the NS documentation for Object:
# isKindOf:
# - (BOOL)isKindOf:aClassObject
#
# Returns YES if the receiver is an instance of aClassObject or an
# instance of any class that inherits from aClassObject. Otherwise, it

So this should do what you want. If you want to exclude the class itself
and only accept actual subclasses of the base class, you could use
([foo isKindOf:aClassObject] && ![foo isMemberOf:aClassObject])

No, this won't work. You can't send class objects instance ("-") methods.
Class objects only respond to class ("+") methods.
You should send the Class object a "+superclass" message to find it's
superclass.

Spam as many groups as you want with one command. Can post same message
to 14,000 groups in just a few hours.
Must have UNIX shell account, the attached script, and create two ascii
text files called groups.txt and message.txt. The file groups.txt should
contain a list of all groups you want to spam, one per line. If you want
to hit everything, you can just copy your .newsrc file, but you'll have to
remove all index numbers and end of line punctuation. The message.txt
file is the actual message you want to spam. It must contain the subject
header on the first line, ie: Subject: Spamming is Fun.
You may add in other headers, such as Organization, Paths, Reply to, etc,
but none are required. Do NOT put in a newsgroup header. The script does
that automatically. There must be a blank line between the last header
and the start of the actual message.
Then, download those two files plus the following script (call it
spamming.fun) to your home directory on the Unix shell account, type "perl
spamming.fun", and sit back to watch the fireworks.

Hi -
It turns out that *root* class objects implement the instance methods
they define. That means that Object implements the method +isKindOf:
along with -isKindOf:. Here is the relevant excerpt from the Object
class description:
-----
Instance and Class Methods
Every object requires an interface to the run-time system, whether it's an instance object or a class object. For example, it should be possible to ask either an instance or a class about its position in the inheritance hierarchy or whether it can respond to a particular message.
So that this won't mean implementing every Object method twice, once as an instance method and again as a class method, the run-time system treats methods defined in the root class in a special way:
Instance methods defined in the root class can be performed both by instances
and by class objects.

Keywords: EOF primary key
I have a project that currently uses DBKit and QuickBase. This allowed me
to do a naughty thing. Instead of bothering with generating my own unique
primary keys I used "id" from the QuickBase table.
These arbitrary keys are entirely fine by me. I prefer not to store
critical information in the key any way.
Enterprise Objects now hides this "id" from view. It is still being used
it just can't be seen in EOModeller so I need to create me own primary
key. I have tables without sufficiently unique rows to build a key from
or at least not in an economical fashion. E.g. An Address table shared
from various other tables. This table has no unique "id" of consequence
and no way of building a compound key efficiently. I have other tables
with similar characteristics.
The key used and now hidden by QuickBase was 8 characters wide giving
62**8 keys. This is an ideal number. Does anyone have a way of
generating such an arbitrary key within EOF or NeXT? I cannot find a
function for generating such a key and I do not want to trap myself again
by using a proprietary QuickBase function call. Any ideas.

Hi -
I assume you are looking for an answer besides "remove one of the definitions"?
You can use the following compile flag in your Makefile.preamble to allow
multiple symbols to be treated as warnings instead of errors. Beware that
the first symbol found takes precedence...
OTHER_LDFLAGS = -Xlinker -m
This is discussed in the "Compiler Tools" release notes for the linker.
I have only used this on NEXTSTEP Developer 3.3 so I'm not sure if it works
as specified on other versions.

Hi. I am developing a LKS using the DriverKit.
The overall picture is a scanner connected to a bit

the machine.
I provide 4k aligned blocks wired down for
the hardware to use. I obtain these using
IOMalloc and then use IOPhysicalFromVirtual to get
the real address for each 8k page.
I then send the data back one 4k block at
a time using MiG with the data inline.
No problem so far, everything works.
Now I want to speed it up. I would like
to use the VM routines to map the data into an
area where the application calling it can get it
and copy it into the pixmap that I am using.
So I have tried using the out of line data.
I have met with extremely limited success.
All of the examples use task_self(), in order to
find where they should vm_allocate the memory before
vm_reading to it.
But I can't use task_self at that level(??)
I have tried almost everything I can think of. I have
used vm_read(kern_serv_kernel_task_port(),...,)
and this seems to work, but I cannot get the data back
on the other side.
I would appreciate any help!! Example code, etc.

Hi all,
Does anyone know how to create a custom event loop to be used
in place of [NXApp Run]?
More specifically, I need to "select()" on a number of ports for
incoming messages from a remote process and to be able to distinguish
between the events from the Window Manager and the ones from the other souce.
Further, once I get an event or message from the Window Manager, how do I
generate an approriate Next event? I assume this would involve doing
"sendEvent:" but don't have any more ideas.
Your help would be greatly appreciated and look forward to hearing
from you soon.

That should have been something to the effect that all classes ``are kind of''

Watch out: some compilers will _NOT_ work with the following code:
void f()
{
int a;
int pa = &a;
// ...
}
My Amiga's compiler, for example, will sometimes complain that you cannot
take the address of a register variable (I say "sometimes" because it
depends on what level of optimization I set the compiler to). The
standard (and defined) way of handling the above problem is to use the
"volatile" keyword.

This is compiler specific.

This can also cause problems. For example, my Amiga's compiler, and some
of my PC compilers, complain at link-time that the said variable cannot be
found.
Again...the only way to solve the problem portably is to use the keyword
"volatile."

OK. The time reported by gettimeofday is _meaningfully_ advanced HZ times per
second.
Doing a quick test on one of my machines showed that the system clock advances
1us per ms (i.e., 1000 times too slowly) between interrupts on that machine.
Is NeXT trying to use the cycle counter to provide greater accuracy but made an
off by 1000 error? Or is the gettimeofday() value advancing according to some
other criteria (like incrementing every N system calls)? I don't know.

True, unless you have a reliable external NTP source to which to synch. I've
toyed with the idea occasionally of writing a NeXT NTP pseudoclock based upon
the TSC--in my experience, it is far more steady than the system clock when the
machine is running. Of course, I have ample free time. :-)
An unmoderated Intel clock is quite bad, generally drifting several seconds a
day. The amount of the drift is about 100 ticks (in XNTPD v3 terms), which
makes me suspect a bug in the kernel. (SunOS used to have a kernel bug which
produced an almost equal but opposite time discrepancy. 100 ticks = being off
by 1 us every time the timer interrupt is serviced.)

What's strange about that?
"const" is ANSI-C. C++ derives in very large part from ANSI-C.

Your compiler's optimizer has bugs with the local variable code in that it
allocates such variables in registers instead of in the current stack frame.

In ANSI C, yes. In K&R C, the defined mechanism was to use the "&" operator
(which also works under ANSI C).

Given a non-buggy compiler, in what situation(s) does using "&" not work?
[ ... ]

If you wish to assume ANSI-C, agreed. However, "volatile" is not defined in
K&R C, so the "&" is the most widely portable solution.

I believe that when the kernel is servicing a higher-priority interrupt,
the clock timer interrupt is discarded, so the system loses a clock tick
every so often.

Organization: University of Michigan EECS Dept.
Message-ID: <44agh7$mao@news.eecs.umich.edu>
Hi NeXTSTEP Gurus,
I'm trying to simulate [NXApp run] by creating my own event loop. The
following is what I got so far (it's not much):
==============
void main(int argc, char *argv[]) {
NXEvent *anEvent;
[Application new];
if ([NXApp loadNibSection:"TestEventLoop.nib" owner:NXApp withNames:NO])
{
while (1)
{
anEvent = [NXApp getNextEvent:NX_ALLEVENTS
waitFor:1
threshold:NX_BASETHRESHOLD];
if (anEvent != NULL)
[NXApp sendEvent:anEvent];
}
}
exit(0);
}
==========
The above main allows the application to run; it can do the target-action
thing. The problem is that the application doesn't seem to "init"; the
application icon remains "blurry" and the delegate of NXApp doesn't
receive the appDidInit: message.
What's missing?
Your help would be greatly appreciated, and I look
forward to hearing from you all soon.
Thank you very much.

Hi again everyone,
thanks a lot for having responded. It has helped me a lot.
I finaly found that my first idea was right: this "isn't" possible
to ask a class if it is a subclass of another class (to my actual knowledge),
neither it is possible to ask an object if it is a class or an instance.
let me explain:
the method -(BOOL)isKindOf: (Class)aClass won't do what I want.
This method asks an instance object if it has been instanciated
by a class object which is a sublcass of another class object.
As a class object is an object - instanciated by its meta-class,
the Class class which inherits from the Object class -, it can be
sent the instance messages defined in the Object class.
A class object receiving the -isKindOf: will try to look if its
class (hence the meta-class) is a subclass of aClass (the class
passed in argument to the -isKindOf: message) which is allways
false, except if aClass is the Object class.
From Object.rtf in Librarian:
"Returns YES if the receiver is an instance of aClassObject
or an instance of any class that inherits from aClassObject.
Otherwise, it returns NO.
When the receiver is a class object, this method returns YES if
aClassObject is the Object class, and NO otherwise."
all this comes from the object organization in objc:
isa = is a = meta level
ako = a kind of = super class
instances classes meta-classes
|-------------------------|
<--| <----| |
------- --------- --------- | |
| isa | ----------> | isa | ------------> | isa |---| |
------- --------- --------- |
| | | ako | ---|(nil) | ako |------
------- --------- ---------
an instance | | <-- | | <------
of Object class --------- | --------- <--| |
the Object | the Class | |
class | class | |
| | |
| | |
------- --------- | --------- | |
| isa | -----------> | isa | ------------> | isa |---| |
------- --------- | --------- |
| | | ako | --| | ako |------|
------- --------- ---------
| | | |
an instance --------- ---------
of Foo class the Foo the Foo
class meta-class
An amazing thing is that the isKindOfClassNamed is apparently bugged:
Object.rtf says:
"Returns YES if the receiver is an instance of aClassName or an
instance of any class that inherits from aClassName. This method
is the same as isKindOf: , except it takes the class name,
rather than the class id , as its argument."
but it justs reacts as I wanted, not as documented (like isKindOf: ) ,
that's to say that if I send isKindOfClassNamed: to a class abject,
it will answer me if it is a subclass of the className passed in arguement.
Try to understand ...
Another thing is there is no isInstance and isClass messages like
in the GNU ObjC.
So I have written a category for the Object class that implements
isSubclassOf: and isInstance and isClass methods.
Any comments and suggestions are wellcome. E-mail me at odp@epita.fr

SUNSOFT INTRODUCES NEO, THE INDUSTRY'S FIRST COMPLETE NETWORKED
OBJECT COMPUTING ENVIRONMENT
SunSoft NEO Debuts; Java-Enabled Web Access To NEO Applications
Previewed; NEO OpenStep Available To Beta Users
New York, NY -- September 20, 1995 -- SunSoft(TM), Inc. today
introduced its NEO(TM) product family, the first complete
development, operating and management environment for object-oriented
networked applications. NEO software (formerly Project DOE) allows
companies to react more quickly to business change by making enterprise
computing more flexible, and more adaptive to business needs.
Available in October 1995, the initial release of the NEO product
family will provide all the necessary elements to immediately begin
building NEO applications based on networked objects. Networked objects
are modular application components or services that are distributed
across a network and shared by numerous applications. These services
are designed to be accessed by other services, as well as by a variety
of clients: including workstations, PCs and even Internet browsers.
NEO products include Solaris(TM) NEO, which is binary-compatible with
Solaris2.4, SunSoft's networked operating environment; WorkShop NEO(TM),
which extends SunSoft's award-winning WorkShop development environment;
and Solstice(TM) NEO tools for administering the object network and NEO
applications. In addition, the NEO product family supports Microsoft
Windows(TM) client interoperability, legacy application and database
integration, and a powerful OpenStep(TM)-compliant desktop and development
environment for graphically constructing and deploying networked
object-based applications. All OpenStep desktop and development
functionality for NEO is included in a follow-on release available
for beta testing Q4 calendar 1995.
Internet access to the NEO environment, via Web browsers using Sun
Microsystem's recently-introduced Javatm (object-oriented programming
language, was also previewed. By providing Web users access to the same
robust computational services employed by internal users, SunSoft opens
the door for true business applications on the Internet, including
electronic commerce and home banking.
First Complete Environment
"NEO provides the first complete standards-based environment for a
new class of more flexible applications," said Bud Tribble, SunSoft
general manager of Object Products. "The result of several years of
development and two years of field testing, only NEO has all the necessary
components for developers to begin creating, running, managing and
integrating true networked object applications into enterprise
environments -- from a robust and scalable object network infrastructure
to a comprehensive development environment to a full suite of object
administration tools."
Solaris NEO -- High Performance Operating Environment
Solaris NEO is the runtime environment for NEO applications, adding
networked object technology to the standard Solaris operating environment
and leveraging such Solaris strengths as scalability and multi-threading
for high performance on an enterprise-wide scale. All new Solaris NEO
applications run side-by-side with existing Solaris applications.
Solaris NEO includes:
OpenStep -- a powerful runtime environment for graphical front-end
applications based on OpenStep specifications. OpenStep is a
market-leading object-oriented application environment and is supported
on multiple platforms.
NEOdesktop(TM) -- a complete, easy-to-use desktop user environment based
on the OpenStep standard. Includes graphical applications such as
Windows Manager, Workspace Manager, Edit, Multimedia Mail and User
Preference.
NEOnet(TM) -- a Common Object Request Broker Architecture
(CORBA)-compliant networked object infrastructure, encompassing an
object request broker (ORB) and set of object services.
NEOshare(TM) -- an advanced networking environment that automatically
finds, manages, and shares services over the network.
For administration, Solstice NEO object administration tools are
bundled with Solaris NEO, supporting enterprise-wide system management
of the object network and of the objects themselves. Administrators
monitor application performance and status, as well as re-deploy resources
without disrupting applications or users.
SunSoft has also licensed object data base technology from Object
Design, Inc. (ODI) and embedded it within Solaris NEO to provide support
for persistence, thus transparently preserving and recovering data that
must persist between object requests.
WorkShop NEO -- Custom Applications For Competitive Advantage
WorkShop NEO, based on CORBA and OpenStep standards, provides an
integrated suite of powerful object-oriented tools for programming a
network. WorkShop NEO includes:
OpenStep Developer -- easy-to-use, object-oriented tools for graphically
assembling three-tiered applications from pre-built, re-usable objects.
OpenStep Developer includes the well-known Interface Builder and Project
Builder.
NEOworks(TM) -- a comprehensive set of tools to develop CORBA-compliant,
networked object applications. NEOworks includes a Network Object
Constructor, OMG-compliant IDL compiler, Networked Object Debugger,
and NEOshare Development Framework.
SPARCworks(TM) -- a suite of intuitive software productivity tools
designed to increase developer productivity and software quality.
SPARCworks includes such tools as source browser, software
configuration management tools, and tools for multithreaded development.
Interoperability Partnerships
As a vehicle for enterprise-wide solutions, the Solaris NEO operating
environment supports software connectivity to relational databases and
Windows clients. Through a partnership with Persistence Software, Inc.(TM),
NEOapplications can automatically access databases from such vendors as
Oracle, Sybase, Informix and Ingres by mapping objects to relational
tables for integration with NEO networked applications.
Interoperability between Windows desktop applications and Solaris NEO
applications is provided through a partnership with IONA Technologies.
IONA's Orbix product provides network access to powerful NEO applications
for Windows applications that use Microsoft OLE.

THE WEB GETS DOWN TO BUSINESS
WITH SUNSOFT'S NEO TECHNOLOGY
Powerful Network Object Environment Spans
Corporate Networks and Internet
New York--September 20, 1995--SunSofttm today announced a
breakthrough technology which enables companies to quickly build
applications that run on both the corporate network and the Internet.
The product line, called NEO(tm), enables the same functions provided by
"in-house" mission critical applications like order entry, financial
services or on-line retail to be delivered directly to customers using
the World Wide Web. NEO will allow companies to get new services and
products to market more rapidly.
Applications developed for the NEO environment provide powerful
computational services which can be accessed from many of the popular
desktop application environments, including SunSoft's Solaris(tm),
Microsoft Windows(tm), and Java(tm)-enabled WEB browsers such as Sun's
HotJava(tm) or Netscape's Navigator(tm). Together with Java, Sun's
revolutionary language for developing interactive Web applications,
NEO extends the client-server computing model to the World Wide Web.
"Our aim is to turn the Web into an interactive and ubiquitous
access point to a world of computing resources," said Janpieter Scheerder,
SunSoft President. "While the Web has emerged as the on-ramp to the
information superhighway, it has provided only limited utility for
real business applications. Now, with NEO, the Web can finally provide
a real opportunity for doing commerce on the Internet."
Java-NEO Combination Expands Web Capability
Rather than using the Internet as a simple bulletin board for
posting and browsing content, NEO(tm) enables Javatm applications to
serve as the flexible desktop "front-end" to powerful computational
resources available on servers spread throughout the Internet. As
a result, Java applications can now access "intelligent" services.
For example a customers can use their home PCs to go beyond viewing
text or images while browsing their bank's Internet home page. With
the Java-NEO combination, the customers see a highly interactive
banking service application. As the customers evaluate a variety of
"what-if" scenarios for a home mortgage, the banking service can provide
real-time information on interest rates, breaking promotional
information or credit criteria.
These services that are delivered to customers are versions of
the same ones accessed by the banks loan office through powerful internal
systems. Bringing these services closer to the customer via the
information superhighway will be a key competitive advantage for companies
in any business.
SunSoft's NEO Transforms Enterprise Computing
SunSoft's NEO object computing environment allows companies to
construct applications from reusable software building blocks, or
"networked objects," dramatically increasing the speed of development
of network applications. High end mission critical applications deployed
in the NEO environment on a corporate network can easily export some or
all of their services to the Internet using Java. Corporate information
managers can now view the Web as an extension of their corporate computing
architecture.
NEO extends the Solaris(tm) operating system with open interfaces based
on OMG (Object Management Group) standards and the benchmark OpenStep(tm)
object application environment specification based on technology from
NeXT Computers, Inc(tm). These open interfaces provide the customer with
high levels of interoperability and maximum industry support.
The SunSoft NEO family consists of three products: Solaris NEO, the
operating environment; WorkShop NEOtm, the development environment; and
Solsticetm NEO, the network and systems management environment. All
three products will be available in October.
SunSoft, Inc., headquartered in Mountain View, Calif. is a subsidiary
of Sun Microsystems, Inc., with offices worldwide. SunSoft's charter
is to design, market, sell and support the industry's highest-quality
software environment for enabling businesses to gain a competitive
advantage through information systems. The products are licensed by
SunSoft and distributed through major computer manufacturers and resellers

NEO BUSINESS ALLIANCE EXTENDING
KNOWLEDGE BASE FOR NETWORKED OBJECTS COMPUTING
New York, NY -- September 20, 1995 -- SunSoft(tm), Inc. today
announced the NEO(tm) Business Alliance, a comprehensive set of Solaris(tm)
NEO programs for system integrators (SIs), value-added resellers (VARs)
and independent software vendors (ISVs). Designed to extend to the
marketplace SunSoft's expertise in networked objects, the NEO Business
Alliance will provide a full range of programs specifically to assist
partners to address such issues as networked object fundamentals,
three-tier client/server architectures, NEO product family training,
design and analysis consulting and implementation of specific solutions.
Already, under the auspices of the Object Alliance, partner Sun
Microsystems Computer Company (SMCC) is moving rapidly with SunSoft
and other qualified partners to set up Object Reality Centers to provide
training, consultation and implementation services for early adopters
developing and deploying financial and telecommunications applications.
Foundation For Success
"SunSoft understands that you can't just throw an advanced
networked object environment over the wall to customers," said Jim
Stikeleather, Partner of Technology, Technology Resource Connection.
"For users to be successful in addressing real-life business problems,
they need knowledge as much as they need products. I have seen many
companies fail with objects because the vendor did not lay a
knowledge-based foundation for success."
"Our goal with the NEO(tm) Business Alliance is to allow customers
to enjoy ready access to qualified expertise as they embrace networked
objects computing," said Bud Tribble, SunSoft's general manager of
object products. "In addition, it will help our channel partners take
full advantage of the opportunities presented by this powerful new
enterprise model as they develop and support networked object-based
systems."
Programs For Systems Integrators and Value-Added Resellers
The NEO Business Alliance provides SIs and VARs with programs
through SunSoft channels worldwide, including access to SunSoft NEO
software and training, the opportunity to work with SunSoft and SMCC
sales channels and the ability to provide expanded service offerings
to NEO users. SIs and VARs can also participate in the NEO Business
Alliance Certification program. Certified partners will also be eligible
to participate in Sun integration projects that require networked object
expertise.
Sun Microsystems Computer Company is the first NEO Business Alliance
partner to implement a program to bring networked object technology and
solutions to customers in the telecommunications and financial industries.
The program has been built in collaboration with SunSoft to certify key
partners that are well versed in working with NEO software.
More than a dozen companies are planning to provide services and
access to NEO technology as part of the NEO Business Alliance, including
AdNovum Informatik AG, Advanced Information Systems, Control Data Systems,
Lockheed-Martin IS&T, NovaDyne Computer Systems, Siemens Nixdorf
Informationssysteme AG, Technical Resource Connection and VALBECC Object
Technology Ltd.
Programs For Independent Software Vendors
Having a large base of third party software tools available early
on to customers has been an priority for SunSoft. "It's important that
our customers be able to harness the power of Solaris NEO right from the
start," said Mary Anderson, SunSoft's director of corporate marketing.
"We've been aggressive in helping leading ISVs grow their object tool
offerings."
To assist ISVs and other developers tap the opportunities
presented by the NEO environment, SunSoft's on-going Catalyst Program
is also participating in the NEOtm Business Alliance. A new Catalyst
Object Program has been launched specifically for NEO developers and
represents complete object development environment, encompassing developer
tools and engineering-level technical support.
More than 75 companies have expressed support for the Catalyst
Object Program. Early members include Cadre Technologies, CenterLine
Software, GemStone Systems, ILOG, MICRAM Object Technology GmbH,
Object Design, Rational Software, Rogue Wave Software, and Tower
Technology. The following companies are now porting their offerings
to the NEO product family include: BLaCKSMITH, C.ATS Software,
Conextions, GS Corporation, Lighthouse Design, Ocean Software,
ObjectLink Technologies, Pangea, Persistence Software, Schema Research,
and YRRID.
"NEO's CORBA and OpenStep interfaces, along with Solaris
multithreading, gives us tremendous leverage delivering high performance,
enterprise-ready frameworks and object applications, said Jonathan
Schwartz, president of Lighthouse Design, Ltd. "Just as important,
the Solaris installed base provides us with a very large market for our
family of products and services."

Hello,
The following announcement (was) made Wednesday, September
20, 1995 at Unix Expo in New York. This announcement, along with
SunSoft's announcement of the NEO Business Object Alliance (a program
to extend SunSoft's networked object expertise into the market) will be
part of a press breakfast being hosted by Sun CEO Scott McNealy.
Key messages:
Sun establishes the Object Reality Program to help customers
move to distributed object technology
* The Object Reality Program is the industry's most comprehensive
effort to help customers create distributed object applications
* Sun's initial focus will be to help the financial services and
telecommunications industries to produce distributed object
applications using SunSoft's recently announced NEO(TM) product family
and other third-party products.
* Object Reality Program includes partnerships with ISVs and Object
Reality Centers, which will help customers build and manage distributed
object applications for the enterprise
SUN LAUNCHES NEW PROGRAM FOR DEVELOPERS OF
DISTRIBUTED OBJECT APPLICATIONS
Object Reality Program to Help Finance and Telecommunication
Industries Move to Distributed Object Technology Quickly
NEW YORK, NY. - September 20, 1995 - Sun Microsystems Computer Company
today announced the Object Reality Program, the industry's most
comprehensive effort to help customers create distributed object
applications. Under the program, Sun will initially assist corporations
in two key industries -- financial services and telecommunications --
to produce distributed object applications using SunSoft's recently
announced NEO(TM) product family and other third-party products.
Based on SunSoft's NEO Business Object Alliance, a program to extend to
the marketplace SunSoft's expertise in networked objects, Sun's Object
Reality Program focuses on taking finance and telecommunications
customers from concept to reality quickly. Included are Object Reality
Centers to provide training, consulting and implementation services for
early adopters. Sun has committed more than $4 million in equipment,
sales and technical support, given its partners access to key strategic
customers, and mounted an extensive certification effort.
"Our goal is to move distributed objects from experimentation to
implementation," said Mark Tolliver, Sun's vice president of market
development. "Doing so means demonstrating the potential for this
technology through working prototypes and pilot projects that meet
specific business needs. The only sure way to succeed is to roll up
your sleeves, assemble the right combination of tools and people, and
build a working application."
Sun's strategy focuses on implementation in a few key industries where
the Object Reality Program can pay the biggest dividends. Financial
services and telecommunications companies are perfect candidates for
distributed object technology. These are industries in which Sun has
already established a strong development base, and in which software is
critical for maintaining a competitive edge. And the business
challenges -- financial risk management and telecommunications network
management -- are made to order for distributed object technology.
Bank of Boston, working with Sun partner Fusion Systems Group, Inc.
provides a vivid demonstration of how the Object Reality Program works.
The bank's new risk management system is one of the first distributed
object applications developed for the financial sector.
"This market moves with the speed of light, and distributed object
technology allows us to change our products on a daily basis to meet
our customers' needs," said Steve Scullen, Bank of Boston's director of
treasury systems. "But there's a real learning curve for this
technology, and you need someone like Sun and Fusion who have the
technical and industry expertise in our market to take you through
every step of the way. The program's biggest benefit is the center's
mentoring approach to what is, in fact, a radically different way of
developing applications."
The Object Reality Program includes partnerships with ISVs who build
three kinds of products needed to create a complete distributed object
environment:
* Software development tools for building distributed object applications;
* Pre-fabricated software objects that can be connected like building
blocks into completed applications;
* And object request brokers that transport these objects over a
network.
The initial tools vendors in the program include NeXT
(NEXTSTEP/OpenStep), ParcPlace - Digitalk, Inc. (VisualWorks), and
SunSoft(TM) (WorkShop(TM) NEO(TM)). Components vendors include several
NEXTSTEP/Openstep ISVs, as well as Rogue Wave Software (Tools.h++).
Object request broker services include Teknekron Software Systems',
Inc. (ObjectBus).
These vendors of application development tools have extended their
products so that distributed object applications can be created and run
under the NEO and other software environments. As a result, customers
can choose from a variety of languages and tools that best meets their
application needs.
CENTERS TAKE HANDS-ON APPROACH
Sun has formed the first three Object Reality Centers, which will help
customers build and manage distributed object applications for the
enterprise. The centers will not just train and educate, but work with
customers to build prototypes, create proofs of concept, and deliver
finished applications. The centers, which are now accepting clients,
will each be operated by a partner with a strong track record in
building telecommunications and financial applications, as well as
experience using SunSoft's NEO product family and other leading object
technologies.
Sun leveraged SunSoft's NEO Business Object Alliance Program to train
and certify each partner. The partners have committed senior consulting
engineers, dedicated facility space, and executive-level support to the
program. The core group of partners can certify other partners to
create a global network of regional development centers.
The Object Reality Centers include:
Fusion Systems Group, Inc. (New York) is a long time Sun partner with
more than five years experience building distributed and object
applications for the financial services market. The company has
expertise in risk-management and derivatives trading, and is expanding
into the telecommunications market.
Strategic Technology Resources (Chicago) is a pioneer in distributed
object technology with more than four years of experience advising
Fortune 1000 companies on optimizing emerging technology. Specializing
in telecommunications and finance, STR is distinguished by its
multiphased project process and unique approach to technology
transfer.
Lighthouse Design, Ltd. (San Mateo, Calif.) with more than seven years
experience in object technology, the company specializes in
NEXTSTEP/OpenStep technology migration. Through the center, Lighthouse
will provide strategic consulting services for financial services and
telecommunications customers ready to move to distributed object
technology.
Sun Microsystems Computer Company is a world leader in the design,
manufacture and sale of network computing systems and is a division of
Sun Microsystems, Inc. Recognized for quality and innovation, the
company's SPARCstation(TM) desktops and multiprocessing servers each hold
the No. 1 UNIX(R) marketshare position. These systems are used primarily

Hi,
IB in 3.3 unparses header files that try to import foundation classes
from local directories (eg. #import "NSObject.h"). From the examples
in the docs it should be getting the foundation headers from
<foundation/foundation.h> but that doesn't seem to exist.
Instead I have been rewriting it as
#import <foundation/NSObject.h>
Is there something that I missed?
Thanks in advance.

I can imagine that the compiler issues a `pointer assigned to int' warning, but

Your compiler's optimization is broken. Unless you explicitly declare a variable as
`register' it should _always_ be legal to take the address of a variable.

That may be so, but the semantics may be different from your human point of
view. -isKindOf: takes an isa step and zero or more superclass steps until it
finds its argument or until it makes no further progress (I presume). For class
objects, one isa step takes you to the meta level, so the argument to
-isKindOf: should be a meta class if you don't want the trivial answer that
only the root class (which is its own meta class) isKindOf: anything (itself).
The documentation for Object in NEXTSTEP simply states this effect, not its
underlying cause.
I suppose you'll need a runtime function to access the meta-class object
(-class has been redefined as +class to return the class itself, for class
objects). Perhaps something like this:
printf("Menu does%s inherit from Window.\n",
[Menu isKindOf:objc_getMetaClass("Window")]?"":"n't");
The rest should be fairly obvious.
Hope this helps (haven't tested it),

Hi,
I'm looking for a table view object as it is used in Mail.app in the preferences, NetInfoManager.app in
the domain viewers, or in Alexandra.app. I have checked all objects in the appkit and EOF, but could not
find such a thing. I know that this kind of view can be done witht the EOF, but I would prefere not to use
EOF objects for this case.
If Alexandra can use it without requiring EOF, it must be around somewhere else.
Many thanks for any pointers.

Hi,
more out of curiosity than for real use, I'd just like to know how applications such as Terminal.app handle user and program
output.
The demo program in the Developer Examples will work fine when using a local shell. As soon as I do a remote login, though, the
remote process will echo the characters sent, and, as the text object also 'echos' the characters, will display all characters
twice.
There must be a way of connecting to a local shell such that this does the character echoing and such that the text object will not
display the characters input.
Many of you out there have written smaller or lager terminal emulators (Stuart, TeXmenu, GatorFTP+, etc) - are you willing to share
this 'secret'?
Thanks for your time, Robert

It's part of the Database Kit, look for DBTableView. The NeXTAnswers document
#1639 provides a good introduction on how to use DBTableView to view non-RDBMS
data:
---
Discovering the DBTableView Object
written by Mai Nguyen
Even though DBTableView is part of the Database Kit(TM) palette, it can be used
separately from the rest of the Database Kit to display tabular data with more
flexibility than the Matrix object offers. This article explores how to use
DBTableView independently from the Database Kit, and gives tips on avoiding
problems with this object.

Whoa Nellie!
I suspect you haven't delved deeply enough into the NeXT documentation...
there is no need to replace the event loop to accomplish said task; NeXT
provided some easy-to-use API for just this purpose.
See:
DPSAddPort() and DPSAddFD().
In general, it is wise to avoid completely re-inventing the wheel! you
will open cans of worms larger and more slimy than you could ever possibly
imagine! While the AppKit has a couple of obvious holes (Text?), it is an
extremely flexible object framework that will often provide most of the
architecture for a particular solution-- but you have to learn to play by
its rules [which are generally pretty reasonable].

See Section 3.8, "Constants" of D&E for a long discussion of how "const" came
into being in C and C++.
A short summary is that Bjarne Stroustrup proposed a "readonly" variables idea
in Jan 1981 for use in his C with Classes "language." Bjarne and Dennis
Ritchie discussed the idea and made some changes. The Bell Labs C standards
group voted to adopt the change in C if "readonly" was changed to "const" but
never implemented the change. Bjarne implemented "const" in C with Classes and
made some changes based upon his experience with it. C with Classes
transmogrified into C++ (Dec 1983). Finally, ANSI X3J11 adopted the original
Stroustrup to Bell Labs C standards group proposal (which had been modified by
Ritchie but not by experience) in the 1989 ANSI C standard.

Using "&" is legal. That is not an issue. However, it may not force the
addressed memory to be allocated space, either on the stack or where
global/static variables go.
As you pointed out in a previous article,

In fact, the standards don't deal with implementational details like "what is a
stack?" or "how are global variables stored?" at all. For example, since C can
be implemented without using a stack, there is no way to force a variable to
occupy space on the stack. (For example, a person reading a C program to
figure out what it does is acting as a C implementation with no stack or global
storage in the traditional computer sense. :^)
Second, if a compiler detects that taking the address seems to serve no purpose
(as defined by the respective standards), it is free to optimize the operation
away, even for non-automatic variables! For example, gcc 2.7.0 will compile
the following C++ module
const int bar = 0;
void foo() {&bar;}
into this (Intel i386 architecture, -O9 -fomit-frame-pointer optimizations):
.text
.align 2
.globl foo(void)
foo(void):
ret
.constructor
.destructor
.align 1
Note that no storage is allocated for "bar." The currently shipping NeXT
compiler cannot do this optimization, but I would think the chances are pretty
good that it will adopt the 2.7.0 revisions by NEXTSTEP 4.0 or 4.1.
Third, "&" can be overloaded to do arbitrary things for C++ classes.
Finally, there is the "as-if" rule: so long as a C implementation produces the
correct output at the correct time and handles volatile objects properly, it
can do anything it wants internally to get these results (my paraphrase, see
5.1.2.3 in the current C standard for the exact language).
To sum up, the "&" operator, practically speaking, will force storage to be
allocated most of the time, but it is not guaranteed to do this all the time.
In fact, there is no portable way to guarantee allocation of storage.

I have been having problems with c++ class definitions broken up over

functions in DLL.cc, I get an error about #include directive being nested
too deep, it bails out. Anyone know about this and how to deal with it?

Thanks to all those people who helped me with how to make lists out of
linked object instances a while ago - works marvellously!
------------------------------------------------------------------------------
Problem (1)
I'm making paths by building them out of a series of clicks into
bezier/line segments. I use instance drawing (which is jolly useful) to
do the following:
{initialise an instance}
{draw the new bit of the path}
{stop the instance drawing}
However now I've finished and written the bit to select the path(s) and
drag the selection the drags with the instance drawing is getting a bit
flickery with the redraws. I use a similar structure to the above method,
but with mouseDragged event as opposed to mouseMoved event and I get
*REALLY* flickery pictures out of the dragged paths when trying to follow
the mouse.
So what I would like to know is - what are some of the usual methods of
avoiding this problem with DPS/AppKit? If you can direct me to a part of
the online 3.0 manual that would be marvellous.
------------------------------------------------------------------------------
Problem (2)
So the user is happily drawing lines in the image and then when he/she
comes to change to the bezier tool to add a bezier segment (moves mouse
outside window and clicks in the tools panel) the panel takes on the role
of first responder and drawing that *SHOULD* be in the document view
proceeds in the tools panel over all my lovely icons and buttons.
How can I stop the panel from getting the first responder?

If you are using the value that results from dereferencing the address of
variable in question in a globally-detectable fashion, the compiler will
guarantee that storage is allocated in dereferencible address space for
that variable.

This is known as "liveness analysis", and code that performs actions on
"dead" variables is "dead code" and can be eliminated in optimization.
Note that this applies to the operations in question; it does not allow the
compiler system to not generate an externally linkable area of storage for
the variable in question if the variable is declared external.
> For example, gcc 2.7.0 will compile the following C++ module [ ... ]
Try declaring the variable as "extern", or have a non-static function which
returns the address of the variable via "&".
In your example, the compiler is simply optimizing away a dead variable
that's local to the "translation unit", or source file. Used
appropriately, "&" will prevent that from occuring.
> Third, "&" can be overloaded to do arbitrary things for C++ classes.
That's true, but so what? You can use #define's to change what everything
means as well.

That's true. Since you can't tell how and where an external variable is
going to be used (for example, let's say you're building a library that
contains this external variable), you can guarantee that an external
variable will have storage allocated for it.

This is not correct. You just have to understand what you need to do.

See above.

Hiho !
Yesterday I tried a DO performance test I'd written six months
ago on an Intel P100.I was surprised about the performance.
Got about 8000 kBytes/s on the loopback.
Today I tested that same program on my 712/80 and got just
3800 kBytes/s maximum. But with 3.2 I had 7900 kBytes/s.
Did anybody encounter the same performance degration since
upgrading to 3.3 ?
Btw. at least NeXT fixed some memorylags wich crashed the
machine using the same program with NS3.2.

Hi,
In Obj-C *all* messages that can be send to a instance of Object can
also be send to a class.
So, you can use "isKindOf" etc.
Good luck.

Hi. I am using a NXBrowser to display a list of objects. The objects
have a string label among their properties. I subclass NCBrowserCell and
store a pointer to the object.
My problem is that Interface Builder won't let me specify what cell
class to use for the browser. During a LoadNibSection, my delegate gets a
browser:fillMatrix:inColumn. But the browser's matrix is of the wrong
cell class, so I can't addRow without getting the wrong cell class.
I know that in browser:fillMatrix:inColumn I could do a
if (![browser cellPrototype])
[browser setCellPrototype:MyBrowserCell];
but this seems like a really bad hack. Shouldn't the cell class be set up
once upon init?
I feel like I am missing something really obvious; please help if you
know.
Thanks,

Is there any special requirements for C programs to print in NEXTSTEP?
Sometime I wrote very short C utility programs which 'fopen' and
'fprintf' datafiles, but I could neither open and write the output
files nor fprintf the output to the console. However, if I run the
utilities in 'gdb', they would fopen and fprintf just fine. I tested
them in sunos, there is no problem with the programs at all. Is there
any trick to make my C programs behaving normally in NEXTSTEP?

That will certainly work for the gcc family of compilers existing today and for
the forseeable future. I tried to find an example relevant to NEXTSTEP since
this is a NeXT group--if you're interest is only in writing NeXT code, use this
technique and it'll do what you want. Frankly, I use it myself.
If you have an interest in other platforms or a theoretical interest, read
on. :-)
Basically, where the "extern" technique fails is when you have a
compiler/linker capable of doing cross-module optimizations such as the
dead-code analysis which Mr. Swiger mentioned. If you declare that a variable
shoud have external linkage but your compiler/linker can determine that the
variable is never actually used, is it legal to optimize it away and not
allocated storage for it? Yes. Do compiler/linker systems exist that can do
this cross-module analysis? I'm not aware of any under NEXTSTEP, but I know of
one (1) on another platform.
Suppose we go further and return the address of the variable via "&" in a
non-static function. Can it still be eliminated? Well, yes, if we can
determine that that function is never used in your program or that at least the
return value is never used. Can NeXT's gcc compiler do this? No, but
compilers do exist which can do this (although they are very rare). In fact,
the compiler to which I referred above is capable of doing inlining and some
dead-code analysis between compiled "object" files, including "object" files
sitting in libraries. That means that storage may or may not be allocated
depending upon the behavior of the other files making up the program.
As far as I can tell from the C standard, all one can say more-or-less
absolutely about whether or not addressable storage exists is that if you
assign the address to a volatile variable, then that address will act is if it
points to addressable storage at sequence points where the volatile variable is
used (in a non-eliminatable fashion) to refer to the storage.
Practically, C compilers are capable of far less. Practically, the "extern"
and "&" hacks almost always work to guarantee allocation of storage. In
particular, they work quite well under NEXTSTEP if you take into account
Mr. Swiger's well-taken proviso about the possibility of dead-code removal.
Practically, even with a very, very smart compiler, a human can always find
some way into tricking the compiler into thinking the address is significant so
as to inhibit dead-code removal. But simply using "extern" or the address
operator doesn't work in _all_ cases; and, theoretically, these common and
useful hacks cannot be guaranteed to work for all compliant C/C++ compilers.

Rather than testing if the prototype has been set each time
browser:fillMatrix:inColumn: is called, set it once, perhaps inside of your
delegate's init method. Other than that, I'd say you're on the right track.
You can also use:
[browser setCellClass:[NCBrowserCell class]];

Look at the _instance method_ setCellClass of NXBrowser.
So you probably want to set the cell class in the nibs FileOwner's
awakeFromNib.

You have not been paying attention. Yes you can. All instances of the
Object object, are also class methods. This is because the the Object class
is it's own meta class or something.
So there is a +init method, it is just not very useful. But this does mean
that if -isKindOf: is implemented by the Object class, than so is +isKindOf:.
Where you have to be careful is where the method doesn't check to see if it
has been called as an instance method or a class method and does the wrong
thing in one case. (Doesn't happen often)

I believe this is an attempt to say that you cannot get at an intances
state via a class object.
BTW:
#import <objc/Object.h>
#import <objc/HashTable.h>
main()
{
id obj1, obj2, obj3;
obj1 = [Object class];
obj2 = [Object class];
obj3 = [HashTable class];
printf("%d\n",[obj1 isEqual:obj2]);
printf("%d\n",[obj1 isEqual:obj3]);
printf("%d\n",[obj1 hash]);
printf("%d\n",[obj1 isKindOf:[Object class]]);
printf("%d\n",[obj1 isMemberOf:[Object class]]);
printf("%s\n",[obj1 name]);
printf("%s\n",[[obj1 class] name]);
printf("%s\n",[[[obj1 class] class] name]);

NSarray retains things added to it, and, when the NSArray is finally
deallocated, releases it's contents. There is no need to do a
removeAllObjects: before releasing the array.

No. Only the names have been changed, to implement OPENSTEP...
NSZone and NXZone are currently interchangable, to ease conversion

First the bad news...
Shared libraries under Release 3.3 and earlier can't be built by people
outside of NeXT itself. Heck, they can't even be built or updated by
people inside NeXT Engineering without serious amounts of burnt offerings,
chicken entrails, and invoking the intervention of Kev the ShlibMiester.
In other words, they were way too hard to configure, and almost impossible
to update.
The Good News...
In the next NEXTSTEP release, 4.0, constructing shared libraries is as
easy as building conventional libraries. Kev and the rest of the Devtools
gang have been seriously busy...

I am afraid I cannot be of much help regarding tools to produce
SGML results. However, some ambitious programer might want to
check out http://www.jclark.com/sp.html
SP (formally known as sgmls) is a free SGML-compliant parser. A
number of pre-compiled versions are on Clark's web site, but I
didn't see one for NEXTSTEP. You will have to take the source
code and recompile it (it is in C++).
I have not looked at it myself; I started reading about SGML and
HTML only last week.
Hope someone takes it and runs with it.

Subject: Workaround for POSIX append bug ?
Date: 1 Oct 1995 22:14:58 GMT
Organization: University of Heidelberg, Germany
Message-ID: <44n3t2$9ab@sun0.urz.uni-heidelberg.de>
Well, there is this nice, well-known append bug with POSIX support in
NEXTSTEP 3.x, which Eric Scott describes as follows:
If you use POSIX at all on the NeXT, there's a nasty bug you should
know about. There is a fundamental bug in the way IO buffering is
handled on the NeXT when using POSIX. Essentially, if you append to a
file with a posix application, null bytes will be written to the file
instead of the correct data. To reproduce the bug, just create a
posix hello-world program and append it's output to an existing file.
The file's size will be right, but it's contents will be null bytes.
This has been a bug since 3.1 on all platforms. It isn't fixed in 3.2
and (I'm told) isn't fixed in 3.3 either.
Is there any workaround if I really need POSIX support for a program ?
mgetty doesn't like BSD sgtty, but POSIX termios is ok. The bad thing
is that the log-file is useless, since it's garbled once you've read
it.

Subject: Compiling GCC on Cube running 3.2

Message-ID: <44n9jo$o3t@elaine6.Stanford.EDU>
Hi,
I've been trying to compile gcc 2.6.0 on a NeXT Cube running the 3.2 OS.
I get a lot of missing files errors when I try to make it. My guess for
what's wrong is that this NeXT used to be on an AFS network, and I believe
they used common include and library files on a remote machine connected
through AFS. So my question is, should I download a new copy of cc for
the NeXT and install it, so I can compile gcc? If so which version should
I get and will I be able to install it without having to compile it, cc
that is? Or is there a way to install gcc without having to compile it?
Thanks,
Patrick

Date: 2 Oct 1995 03:33:55 GMT
Organization: University of Michigan EECS Dept.
Message-ID: <44nmj3$eec@news.eecs.umich.edu>
Hi,
While writing an object to a stream, I encountered a very strange
behavior in "- write:(NXTypedStream *)stream." The first statement in the
method is "[super write:stream]," and the problem is that the execution
suddenly gets out of NXWriteRootObject () while executing this statement.
"super" is the Window class.
The application seems to behave normally otherwise; it just wouldn't
do [super write:stream]. The funny thing is that I very often use the
read: and write: methods in my applications and that this is the very first
time that I encountered this problem.
Any help on this matter would be greatly appreciated. I eagerly
look forward to hearing from you all.

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

The corresponding code should be somewhere as Edit.app uses

I also searched under InterfaceBuilder.app where a table for

Hi All,
We are currently developing a Next app using Sybase 10. We are using the Sybase 4.6 client lib as supplied in Nextdeveloper 3.2. We are encountering a memory error and wish to see if anyone else has a similar problem. We think the error only happens when accessing Sybase and after a number of successful Sybase calls.
We have tried the malloc debugger and this prevents the error from arising so we cannot debug the error!!
Does anyone have any suggestions?
Many thanks in advance

I am trying to use an NXConnection for the first time. I am trying
to create something that will run 24x7 on a machine, have no interrface,
accept connections from other processes and do all of the work for them.
Thanks to the help of others before, I have this almost working. My
current problem is that the program accepts a connection, processes
everything, then exits. This leads me to the speculation, from what
I've been able to find and read, that running a connection is good for
1 and only one connection. I can't figure out how the connecting program
should gracefully release the connection so that some other program can
get it.
Is this a correct assumption? Is there something to connecting process
should do so that the server does not get the connection invalidation?
Thanks for any help

Several of my top clients across the country are ramping up for major NeXT
development projects that will be rolled out in 96/97, on several
different hardware platforms.
A common feature in these new development efforts is the use of new
development and OO products such as NeXTStep 4.0, OpenStep, Hot Java, EOF,
Windows NT, Solaris and Webtools. Which will run on NeXT, Intel and/or Sun
I would like to hear from NeXT development professionals with experience
in any environment (software vendor, banking, insurance, consulting,
Fortune 500).
You must have a minimum of 12 months NeXT experience (exposure to Sybase
or Oracle would be a plus), and live or want to live in the following
areas:
New York City, Washington DC/Virginia, Florida, Chicago, or Colorado.
Salaries are excellent, as well as the per diem and project rates.
New York and Colorado are very hot right now!!!!. Call me for more

Subject: How can I temporarily exclude mouse-moved events?
Hello,
Our application accepts mouse-moved events to keep track of the mouse
location. This works fine, but if you move the mouse around during
long operations when the program is busy (even if you've switched
your focus to a different application) the mouse-moved events pile up
and overflow the event queue, resulting in a *huge* stream of "Event
Discarded" messages in the console.
I've tried setting the window's event mask to NOT accept mouse-moved
events during these lengthy operations, and then set the event mask
back again, but this didn't seem to work. So I'm wondering if
somehow the app needs to return to the event loop for the mask change
to take effect, or what? Or maybe there is a secret application-wide
event mask separate from the window's event mask?
Does anyone know anything more about how events are processed and at
what level the masking of events occurs?
I suppose I could try clearing out all mouse-moved events from the
queue periodically during my long operation, but that seems like a
very inefficient approach. Setting an event mask seems to prevent
the unwanted events from ever getting put in the queue which would be
much better.
Thanks for any help.

Subject: Driver for DeskJet 600C for ghostscript
Hello,
I am trying to use GhostScript to print to a DeskJet 600C on an Intel NeXT.
(parallel)
When I print, the print head makes noises, but never does put anything on the paper.
I have been trying to use the DeskJet 550C driver (cdj550c) (the 550C driver
under Windows 95 works for the 600C as well), but I guess it doesn't work on
NeXT.
So, does anyone know if there is a GhostScript driver for the HP DeskJet 600C?

NEXTSTEP uses different start-up code posixcrt0.o instead of normal crt0.o
if you compile posix source. The problem you are referring to, happen when
you link the NEXTSTEP start-up code with posix library. Add -posix flag to
you your compiler flags to tell the compiler to compile correctly the
posix source and link it with the posix start-up code.

You can set an event filter function for your application that can filter out
the unwanted events. Use a global variable in the function's source file and an
access function to set and clear the flag. The filter function will remove the
unwanted events and they will never get to the queue. Look at the function
documentation for DPSSetEventFunc(). You will know your way from there..

Do The Euphoria Tape alone the first time, and then
with a lover. It's a phenomenon you will feel within
the first 3 minutes of use -- what you feel the rest of
the time is unbelievable.
The Euphoria Tape.
It was first whispered about on college campuses, and
only experimented with in seclusion, or among close
friends in private settings, but it has now become a
cult rush and is considered the next passion of our
Cyber lifestyles.
The Euphoria Tape.
Not a drug, not a chemical, but an audio stimulation of
brain centers controlling pleasure. And agony. And ecstacy.
The buzz. An audio mesmer signal strokes the base of the
mind, choking out pain sensations and producing the violent
flow of... euphoria.
The Euphoria Tape.
Copies have changed hands from friends to friends to other
friends. It is not regulated, there are no laws yet restricting
use of The Euphoria Tape.
The Euphoria Tape is rushing the masses.

Date: 4 Oct 1995 19:36:28 GMT
Organization: University of Otago, Dunedin, NZ
Message-ID: <44unns$k54@celebrian.otago.ac.nz>
Keywords: Text
I am wanting to create a subclass (or category - I haven't decided which
yet) of Text to do fully justified text (hopefully taking into account
kerning too). From reading the documentation, it seems that the main thing
I'm going to have to do is to write my own drawFunc and scanFunc and set
them as the function at the appropriate place.
I have several questions about this:
First of all, has anyone else tried this before? Successfully? The
documentation on the functions seems very skimpy - any help would be
appreciated.
Do my functions have to handle all the justification modes for redraws to
work etc, or can I use different functions for different parts of the text
- something like:
- setAlignment:(int)mode
{
if (mode == NX_JUSTIFIED)
{
[self setDrawFunc:&justifiedDrawFunc];
[self setScanFunc:&justifiedScanFunc];
}
else
{
[self setDrawFunc:&NXDrawALine];
[self setScanFunc:&NXScanALine];
}
return [super setAlignment:mode];
}
Do I need to change the setSelProp:to: method too, or does this just call
setAlignment:?
When I get the layInfo in the scan function, does that tell me where I am
in the text object? Has calcLine already done its job?
I would like to make a generic text object subclass/category which will
fully justify test, but if need be, I could work at a lower level for this
job (probably using Font objects because they have the kerning tables
built in). Is it reasonable to do what I am proposing with the text
object, or would it be better for me to work at a lower level?

In my opinion, you can't instantiate own subclasses of NSObject in

I didn't find a way and didn't hear of anything. Now I declare all
classes that I want to instantiate in IB as subclasses of Object.

Hi,
I'm having link errors when I try compiling on my NeXT Cube running 3.2.
cc compiles everything fine, but when ld tries to link the object files I
get the following error.
ld: Can't locate file for: -lcrt0.o
This NeXT had many of it's libraries on a common AFS server, but I've
managed to copy most of them over (and even get AFS running, sort of), but
does anyone have any idea what I'm missing?
I'd really appreciate any feedback on this.
Thanks,
Patrick

Gideon,
We have been working with the NeXT Text object over the last 18 months on
various projects, and we are currently preparing to release a native RTF word
processor that uses our subclasses of the NeXT Text object.
The good news is that yes, we have proven that it is possible to produce a
fast, elegant subclass to the Text object that not only handles justified text
and kerning, but also right, decimal and centre tabs, scaled text and graphics,
pagination, .....
The bad news is the cost in time and effort to do this. As you have found, the
documentation is very sparse in this area, and although the original author of
the Text object did an extremely good job, it is a complex implementation that
has taken us a long time to completely understand.
Once we have released the word processor, we will palettise our Text subclasses
and make them commercially available to other developers.
NeXT have also been doing a lot of work on a new Text object which includes
kerning and I believe will be released with NEXTSTEP 4.0 next Summer.
I shall try and answer some of your questions:
> Do my functions have to handle all the justification modes for redraws to

> [self setScanFunc:&NXScanALine];
> }
> return [super setAlignment:mode];
> }
The scanFunc is called whenever any part of the Text needs to be drawn or
recalculated. Hence, assuming your text would include a mix of justified and
non justified paragraphs, you could check if the particular line is justified
and if not call the NXScanALine function otherwise call your own.
However, you did mention doing kerning - in which case you will want to handle
all forms of alignment.
> When I get the layInfo in the scan function, does that tell me where I am

The calcLine method calls the scanFunc to do it's job.

You will need to work at the Text level, but of course that will involve a lot
of low level very efficient C, as well as working closely with the Font class.
I would recommend you look at what we have done with CedarWord when it is
released to see how much can be achieved with the NeXT Text class.
Best of luck,
Paul Heffernan, Product Development Manager.

Hello,
Is there any easy way of preveinting a text object from beeping at me when I enter an invalid key?
I'd like to suppress the beep for certain keystrokes.
I have installed a filter which will grabthe keys, send them elsewhere and return 0 instead of the key
pressed. Returning 0 will cause the text object to beep.
Thanks for any pointers,

There is one, but when I asked Informix if they had a port to NeXTSTEP
they asked me what is NeXTSTEP. Okay it was the UK office but I got no

Subject: HELP: Can't remove empty directory
I'm having a problem removing an empty directory which has an erroneous
size (of 74670080 bytes) after an system crash.
A system crash (a Window Server death) seems to have garbled the
'/usr/lib/NextStep/Workspace.app/WM.app/English.lproj' directory leading to
an 'please logout' message just after loging into the Workspace. After
reboot 'fsck' paniced and requested an manual 'fsck'. This time 'fsck'
complained that this directory formed an extraneous link to somewhere into
the colorpicker nib-files (I don't remember the exact directory/file) and
suggested to remove it, which I permitted. This left me with an garbled
directory.
Afterwards I could list the content but 'pwd' en 'cd' gave an error
concerning the inode and the size is also weird. After another 'fsck'
(which listen no errors), I tried to remove the directory (with 'rm -r')
which succeded for the contents but now I still get the message that it's
not empty while 'ls -al' won't list any files (beside '.' and '..' of
cause). After a rename with 'mv' the problems with 'pwd' and 'cd' are gone
but I still can't remove the directory.
So I'am lost. Any suggestion before I have to format the disk just to
reinstall '/usr/lib/NextStep/Workspace/WM.app'.
Please reply by mail, I only get the daily digest of this newsgroup (and
I'am hoping to solve this evening (localtime=GMT+1)).
Thanks in advance.
Wiro.

Some good adventure games for Nextstep would be nice. Nextstep is starting to have some
very serious, competitive programs. But something on the lighter side, like a adventure game,
would be very welcome. :-)

Hi,
Before there are any more uncertainty and misguided thoughts on this
thread, I thought I should post the answer (since I started it in the
first place).
I have had several responses to this and here is how to fix it. You
need to add a category to NSObject to support 6 additional methods.
Clip the following lines between the dashes and save it as
NSObject-IBFixes.m
Add this file to your classes folder in PB and recompile. You are
now on your way to dynamically instantiating NSObject subclasses in
IB.
..Mike.

You can just link against libg++.a (i.e. put -lg++ on your link line).
strdup is really just the equivalent of the following, though:
char *strdup(char *str)
{
if (str)
{ char *str2 = (char *)malloc(1 + strlen(str));
if (str2)
{ return strcpy(str2, str);
}
}
return NULL;

hello,
i am really getting annoyed with this ILLOGICAL and
scandalous lack of FULL text-editing possibilities (ie Edit.app
-like) within IB :
- using standard palettes you have apparently the following
choices:
* use TextField and you have no possibilities of editing
individual subparts and no sub/superscripting
* use ScrollView and you get the above but you keep the
scroll bar!
- i didn't find anything within MiscKit...
- AND i don't want to program the stuff: if IB can't let you
input some plain scientific text with minimal decorations
what's its use? (I am not talking about full formula
capabilities, I've got EquationBuilder for that!).
If anybody knows a workaround, please let me know...
(i am under NS 3.2 - if 3.3 is any better, let me know!)
thanx everybody!

#define strdup NXCopyStringBuffer

I've heard of it already several months ago. I'm still trying to get
Informix or our Next-reseller to tell me how much it will cost and how to
get it. However no one seems to know???
I heard that the EOF-adapter has already been develop by Informix Germany
(they live nextdoor to Next-Germany), as was the DBKit-adapter we're
currently using with official no support and constant changes in the policy
of this adapter becoming an official Informix-product. I'm very eager to
switch from DBKit to EOF and Foundation-kit as I'm now constantly
handcoding how to map objects to tables efficiently. This spring our
Next-reseller offered us to develop this adaptor but we've declined because
we we're promised that the EOF-adapter would be an official
Informix-product Q2'95.
My last information from our previous accountmanager at Informix (we get a
new one every month, must be a nice company to work for :^) was that
Informix was negotiating with Next and HP about which company should
support it. I think that Informix would like Next to deliver the adapter
free with NextDeveloper like the ones from Oracle and Sybase but let Next
also handle the support.
I personally also suspect Informix from stalling supporting the
Next-platform because of their own object-oriented development environment
NewEra.
Although I'm technical content with our Informix online database, I regret
we've choosen Informix instead of Oracle. At least on the Next-side it
would have saved us a lot of trouble.
But I can't image that the 'largest unix-database supplier' would want to
leave all those Next-developer to Oracle, Sybase or Interbase.
Maybe we can start a signaturelist to convince Informix that there are
Next-developers who want to talk to a Informix database out there.
Wiro.

If I understand the question right, just make a matrix of browsers. Then set an ID to point to the
active browser(could even have a mouse action that handels that, goes to the browser that the mouse
in currently in), and send the messages to the active browser id. Hope that is what you were

What do you seem to think is missing (there are things that aren't bundled
with NEXTSTEP that come with Pixar's PhotoRealistic RenderMan Toolkit, but
the two main parts - the renderer and the shader compiler are there).
Pixar sells PhotoRealistic RenderMan for a variety of platforms - let
me know which you're interested in, I'll be happy to pass it on to
the sales folks.

"OpenStep allows businesses to build, deploy, and maintain object-oriented,
three-tier client/server applications for environments from a variety of
vendors: NeXT, Sun, Hewlett-Packard, Digital, and Microsoft. OpenStep-
compliant objects and applications communicate transparently with each
other, regardless of the underlying operating system."
THE OPENSTEP INITIATIVE
In November 1993, NeXT decided to "open" NEXTSTEP and publish OpenStep, an
API to an object layer standard based on NeXT's advanced object technology.
The OpenStep specification is available on the ftp server: ftp. next. com.
OpenStep-compliant environments will provide a distributed, object-oriented
application environment, allowing objects and applications which use the
OpenStep APIs to be portable across multiple implementations regardless of
the underlying operating system. A preliminary version of the OpenStep
specification was published June 30, 1994 and the final version was
published on September 30, 1994.
OpenStep applications will be portable to the entire range of OpenStep and
NEXTSTEP platforms and will interoperate with NeXT's PDO and EOF object
server and object persistence / database products.
Versions of OpenStep have been announced for NeXT's MachOS, Sun's Solaris,
Digital's UNIX, Microsoft's Windows NT and Windows 95.

I'm trying to get the very cool looking MiniSQLAdaptor for EOF running, but I'm

compiler warns me:
MiniSQLAdaptorChannel.m:667: warning: `MiniSQLAdaptorChannel' does not respond

And sure enough, when I try to do anything with it, I crash with the same error at

I'm using what I found on cs.orst.edu the other day, and the patched msql that is kept at
StepWise. Is there anything obvious that I'm doing wrong?
One other question: does one pronounce MiniSQL as MiniSequel, MiniSeekle, or
Miniscule?

Maybe it works in single-user mode. Did you use chmod? Or try

I need to try out a animation/testing tool on some typical NextStep apps
preferably in the telecommunication (ie. customer care, billing, rating,
etc.) and financial app (ie. trading, customer care, risk management, etc)
area.
At the very least, I need a description of the app's features and its
analysis and design info (the more the better) in order to build a prototype
of it. Even better would be if the source code is available on a server
somewhere that I can download.
Obviously, I am presuming the commercially developed products will not want
to provide any of this info, so I am hoping there is an 'educational' site
containing such info.
Any ideas on assisting my search for these app types would be appreciated.
Please respond to 'rsmallwo@islandnet.com'.

Organization: University of Maryland, Chesapeake Biological Lab.
Message-ID: <459tng$7kb@gamera.cbl.cees.edu>
Keywords: floating exception
Basically, some of the applications (GNU utilities, tcsh, etc) we have
compiled off the net either die outright all the time with the aforementioned
exception or do it "sometimes." This is highly irritating. The hardware we
know works fine, it's a TRITON motherboard 100Mhz Pentium system with 256K
cache, 32MB fast page mode RAM, DPT 2024/PCI SCSI controller, COGENT 960 PCI
ethernet, and ATI GUP 64. I have the NextDeveloper 3.2 CD loaded but we
have tried coimpiling with a freshly built GNU 2.7 compiler as well.
When compiling we tend to use libposix as it is the only way it seems
we can get most things to compile (and that can be problematic at times
on some apps yielding ld errors during link for duplicate symbols).
I'm wondering if we are going about compiling these utilities the wrong
way. Any advice?

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be

REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different

About compiling GNU utilties, tcsh etc under nextstep.
You mentioned using libposix as the only way to get things to work.
This shouldn't be necessary, i have tons of gnu stuff installed on my
Sparc running 3.3 and it was all compiled without using the posix
junk.
all it should take for the gnu stuff is typing configure then make.

Greetings,
We're having some major difficulties with EOF. We can't seem to talk
to more than one database at a time. In the following code example,
I've tried to create two EODatabaseDataSources, connected to two
different databases, and fetch objects from each. When I try each
section of code separately, they work fine. But if I try to use both,
the second one fails during the fetch, with the following console
output:
** otto> EOFTest
** Got 2 objects from data source 1
** Oct 9 15:09:38 [578] Sybase Server:unknown Procedure:none Line:1
** Message:Invalid object name 'CustodianInfo'.
** No array returned from data source 2
** otto>
'CustodianInfo' is a valid object, since access to data source 2 works
perfectly by itself.
Both of these databases live on a Sybase server. I have run the same
experiment with two QuickBase databases, with the same results.
We are running NS3.3, and EOF 1.1.
Any suggestions on what we can do to fix this will be most appreciated.
Many thanks in advance,
Brian Baker.

I think that there will be a 3DKit clone available for OpenStep,
based upon OpenGL as the underlying renderer (for "real time" stuff
at any rate). But I have heard rumors here and elsewhere about
the possibility of the 3DKit being dropped. If it is, I'll do
what I can to see that it isn't lost forever, as I have done with
the PhoneKit/IndexingKit petition. (The "petition" may be found
in ftp://ftp.thoughtport.com/pub/next/misckit/ )
I know that not much news has been forthcoming on the results of
that, and I can't say what the final results will be until they
become final, but the petition has gone to NeXT and the response
so far has been very positive. I feel that if they were to
unbundle the 3D Kit then NeXT's response would be similar to what
I've seen with respect to the other two kits... And at least some
of the people at NeXT seem very happy to work with me on this, if
for no other reason than the fact that it is a win-win for NeXT
and it's customers.
> How about an update of QuickRenderman? Am I asking for too much?
Probably, yes.
I'd suspect that if 3DKit were moved out of NEXTSTEP/OpenStep, then
you'd have to hook in your own renderer, perhaps based upon OpenGL
or some other such beast.

I started writing an adventure system around 5 years ago on an Acorn
Archimedes System (any of you people in USA ever heard of it - it had
the faster RISC processor you could buy for less than $2000 - it was cool!).
Anyway, when I upgraded to a NeXT system I ported the system to that but then
forgot about it for a long time. Last year I recoded the whole thing in C++
(most of it) and have recently started reworking the Adventure description
parser. Right now - its not usable, but it is on my list of tasks for later
this year. I would like to hear from anybody wishing to provide encouragement,
ideas or testing (by writing some adventures).

This has been pointed out 1,000,000 times before in this forum, but why not
make it 1,000,001 ? Maybe this time somebody will remember it.
First of all, don't compile posix, unless you have to. Posix support
under NS is still not entirely stable and tends to bloat the size of even
the smallest executables. Most programs on the net using posix features
can be compiled posix-free, possibly after munging the configuration
slightly.
Second, if you do have to compile posix, do _NOT_ (!) -D_POSIX_SOURCE or
'#define _POSIX_<FOOBAR>' or -lposix. The effect will be to compile in an
environment which has been only partially posixified with entirely
unpredictable effects. The correct way to compile posix is to add the
'-posix' switch to all invocations of cc. The most simple and reliable
way to do that is to define 'CC' in the makefile to be 'cc -posix' (and
you may want to throw in the -pipe switch at the same place).
And, yes, ncftp 2.x will work just fine when compiled in this manner.

The open panel is going to begin at your current working directory which,
in the case of a debug session, is the app-wrapper. However, when you
double-click on an app to run it, it is your home directory. I wonder
if you are accessing other files using a relative path and not the
complete path to your application? To create an application-relative
path, use NXBundle to find out where the .app (or .debug) lives:
[[NXBundle mainBundle] directory];

You need to install your application where the WorkspaceManager will
see it, and therefore, know about your icons. You can do this by:
using workspace to copy it to /LocalApps
using workspace to copy it to ~/Apps
dragging the application to the dock

I posted this a week ago and haven't gotten any helpful answers. I am
still having the same problem and nothing I have tried has worked.
I am trying to use an NXConnection for the first time. I am trying
to create something that will run 24x7 on a machine, have no interrface,
accept connections from other processes and do all of the work for them.
Thanks to the help of others before, I have this almost working. My
current problem is that the program accepts a connection, processes
everything, then exits. This leads me to the speculation, from what
I've been able to find and read, that running a connection is good for
1 and only one connection. I can't figure out how the connecting program
should gracefully release the connection so that some other program can
get it.
Is this a correct assumption? Is there something to connecting process
should do so that the server does not get the connection invalidation?
Thanks for any help

I've been using
if ([savepanel runModalForDirectory:directory file:name])
which I thought returned the directory and file. I then build a
complete path to the file and use
ts = NXOpenTypedStreamForFile(openFile, NX_READONLY);
The char str openFile contains a correct complete user path,
e.g. /Users/woo/projects/scipuff/file1.dom
It then says it can't open it (i.e. ts is returned as nil when app is
run , but works when run in debugger).

Please, please, dear NeXT Inc, make this happen (along with an SGI port for
the whole OS)...
The 3DKit is too vital an extension to the concept of NS to drop it. The
rule "PS for 2D, RIB for 3D" should hold, even if the main OS customers
like banks etc. don't need it. Besides, keeping it would be a chance to
define something like an object-oriented standard for off-the-shelf (i.e.
general purpose) 3D programming. Just improve the 3DKit that tiny little
bit to make it really worthwhile...

I have a NeXT Dimension System running NS3.3. At one time it was networked
to a NeXT Cube. Subsequently, I did a complete, including disk formatting,
installation of NS3.3. However, I find that about 50% of the time upon
powering up and rebooting, the system hangs waiting for a network connection.
Usually, I can do a hard reset (Alt-Cmd *) and, after a long-long time, it
finishes fsck on my 1.3 GB HD and sucessfully completes the boot process.
To the best of my knowledge, no network configuration files have been altered
to accomodate a net connection. Question: what am I doing wrong? Is this
a hardware problem? Is this a bug in NS3.3?
Thanks for your help,

Just to second Carl. I got ncftp working without any posix support at all.
The problem with ncftp is all of the termio stuff that the configure script

In a search for NS compatible notebooks, I've been noticing that the Chips &

a driver for this. However, such a driver would open up the possibility of
using all sorts of generic Notebook systems with NS in color.
This has left me wondering how hard it is to write a video driver for NS
3.3? Not that I have time to do it, but I am curious. . . .
(hint: anyone else out there have time and want to write a driver?)
I really am curious about this. NeXT claims driver kit makes writing
drivers much easier (than what?) How easy is it (for a simple, working,

Message-ID: <45gtf7$q2j@fnnews.fnal.gov>
I've installed NextStep for Intel release 3.2 on my 486 VLB system and it
all works well in Normal VGA mode. However, when I try to use the system
at SVGA resolutions using my Hercules Dynamite Power VLB 2 meg DRAM card, I
can't get the system to display things properly. The system boots up but
the screen usually is just a shade of grey. It does not work at any resolution
that is supported by the driver. I've tried with different multisync and SVGA
monitors and the same problem results, so I think it is a problem with the
driver or the card. My card has an acumos ADAC1 and I've noticed that the
supported ramdacs in the ET4000w32p driver are the ATT20cxxx and the STG1702
so this may be the problem. I've also noticed that this driver has different
configuration files for different resolutions. It seems that one can program
the cards registers for different setting and resolutions but I have no idea
how to do this. So I'm wondering if there is a fix or update for this driver
or is my card not supported at all even though I have the necessary chipset.
Also, is there any info on how to program different card registers using
the driver configuration (*.vc) files?
Here's what a configuration file looks like. Can anyone make any sense out of
it?

Gerd has a point, and arguably the largest name in visualization, SGI, dove into
the financial market software business back in June with this press release:
NEW YORK, June 27 /PRNewswire/ via First! -- In conjunction with the
opening of the Securities Industries Association Information Management
Conference, Silicon Graphics, Inc. (NYSE: SGI) today unveiled the
Silicon Exchange(TM) initiative, an integrated solution set of software
and hardware for financial service institutions. Silicon Exchange
combines third-party graphical software and innovative financial risk
management technologies with Silicon Graphics'(R) visual computing
systems, database servers and advanced software tools. The Silicon
Exchange initiative builds upon Silicon Graphics' long-standing
leadership in interactive 3D graphics and digital media technologies to
offer the financial services industry breakthrough tools for competing
in today's global economy.
A friend of mine from Wall Street (who if he's reading this, should send me his new

I also think some of the NS ISVs and SIs have done some interesting work with

Ask again. Maybe ask Informix, US. Or ask NeXT, Inc. for who you have to

Hello experts,
It's Stupid Question time again (really, and about such a trivial---yet
central---issue).
Can anyone give me a reasonable explanation of why -[View
displayFromOpaqueAncestor:::] is the exception? Why doesn't -[View display:::]
do all that? Isn't it a View's task to know whether it is opaque, rather than
that of whatever asks it to display itself? Or to update itself? Now, those
nice abbreviations/update machinery are out of reach for those Views which
correspond to the default (not being opaque). What display::: now does would
then be called incrementalDisplay::: or something, and would not be of much
use, except perhaps internally.
Am I blind, or is the emperor indeed without clothes? And how to handle this:
let an imposter redefine display::: as displayFromOpaqueAncestor::: and poseAs
View, or just redefine implementations of display and display::?

That's a good question and one that I've wondered about myself for a long
time. I find myself writing the following code whenever I write a View
subclass that is always transparent (i.e. that doesn't do a NXRectFill or
somesuch in drawSelf::):
-display
{
return [self displayFromOpaqueAncestor:NULL :0 :NO];
}
Every time I copy/paste that code in, I say to myself "why isn't that
in the base class method?" The only plausible answer I can come up
with is that, for this code to be in View, the view would have to ask
itself if it was opaque, using [self isOpaque], in order to know whether
to call displayFromOpaqueAncestor. I have found that [self isOpaque]
isn't always answered correctly by all the view classes contained in
the AppKit (in particular false negatives) so the above logic couldn't
be handled correctly in the base class if isOpaque wasn't reliable.
Conjecture, pure conjecture.
By the way, yes, I could make a simple View subclass called TransparentView
that contains just the above -display method, thus avoiding copy/paste of
that display method in other classes; however, with single inheritance,
you're stuck if you aren't subclassing from View, am I frequently am not.

Subject: Implementing Inspectors - please help
Date: 12 Oct 1995 18:54:29 GMT
Organization: Global Election Systems
Message-ID: <45jo95$anq@grid.Direct.CA>
Hi. I am looking for pointers on the Right Way(tm) to implement inspectors.
I have a browser of objects and want the user to (optionally) look at
the attributes of the object. I have a browser controller to handle
the browser window and an inspector controller to handle the inspector
panel. My app basically has multiple browsers for different object
types and a single inspector panel for looking at the objects and
modifying their attributes (kinda like IB). There seem to be two schools:
(1) Keep the inspector controller object around even if the inspector is
not requested by the user. OrderFront the inspector panel when the user
requests the inspector. I don't like this option because updating the
inspector in my app is expensive (the attributes take considerable resources
to compute and a non trivial memory overhead), and the "usual" case will
be that it is not displayed.
(2) Create the inspector controller when the user requests an inspector. I
don't like this option because (a) I can't hook up the target of the
NXBrowser in IB to anything since the inspector controler object doesn't
exist yet (the browser window also has new and delete buttons, etc);
(b) the browser controller then needs to be notified when the
inspector closes (or another browser gains control of the inspector), so
that the browser controller can free the inspector controller and unlink
the target of the NXBrowser.
I have tried (2) because my gut tells me (1) is a solution of the
"easier to program but less efficient" variety. (2) however seems to
bog down in the details when it actually comes down to keeping track
of multiple inspector types for multiple active browsers, so I am stuck.
Any hints from those who have "been there done that" are very appreciated.

Interesting. Where did you hear this? One would think I would have

Don't hold your breath.
I am working very hard to get the prman that ship with NS to be
current for the 4.0 release, but it's really not on anyone who
matters short list (mine included), so...
As for qrman, while it's clearly the right thing, other than a few
folks like Guido (solidThinking) and that wacko academic wave (WavesWorld)
no one has done anything to justify the continued existence of the 3DKit.
Sad, but true.
If you want the 3DKit to survive 4.0, use it.
If you want qrman to prosper, use it.
Things die for many reasons, but the many reasons for the 3DKit to
(potentially) die are not political, they're pragmatic. How many seats
does it sell? Do you use it? Do you care? If you do, use it and tell
NeXT about it.
Tell NeXT it matters, and be able to show them why. If you can,
I honestly believe it will survive, but it has to sell seats, it
has to be important. It is to me, but I'm a mutant... :-)

Subject: Compromise
Hello,
I have been programming with NextStep since '91 and I'm an advocate
of object-technology in my own particular domain (Computer Algebra).
I'm really worried about the NeXT statements about OpenStep, especially
by the fact that it will supposedly replace the "old" (but, stable and
proven) appkit and that NextStep 4.0 will only provide binary (not source)
compatibility with previous versions of NextStep.
To me, (personal opinion !) the decrease in quality of the OpenStep software
(including the related Foundation Kit, EOF etc.) compared to the "old" NextStep
is so obvious, that I can't understand why NeXT is even thinking about doing
this, but I admit that I have met people that sincerely believe that the "new",
complete rewrite (with more static typing, with more protocols, more additions
to the objc language etc, with new allocation conventions, and with the use of
objects "throughout", even where C functions did the job just fine), will
improve quality and portability of the system.
So, rather than starting a flame war about it, I'd like to suggest something of
a compromise. Isn't it possible in 4.0 (and beyond?) to keep source
compatibility and to add OpenStep as an "option" for those that like OpenStep
and want to start developing OpenStep software using NextStep 4.0 ? For example,
the NSWindow header file could be placed in <openstep/NSWindow.h> and the Window
header would just stay where it is right now <appkit/Window.h>. I mean: let's
keep the good old NextStep around for a while, and also give us a possibility to
"try out" or evaluate OpenStep (by importing <openstep/openstep.h> !), and
please give us a choice on whether to convert NextStep software or not.
I have the impression that the OpenStep people would prefer a complete removal
of the "old" appkit, even before we have had a chance to evaluate the
replacement, and would like to deliver a few tools to semi-automatically convert
source code towards the "new" API, probably hoping of course that this would
spur the development of more OpenStep compatible software. That's a dangereous
bet. If I'd be forced into this kind of position where I have to choose between
converting (not to mention rewriting) my software, or just quit, I'd myself be
more likely to quit and drop OpenStep at all. On the other hand, there's
definitely a lot of potential in OpenStep, and I'm very willing to take a look
at it, but on a voluntary basis of course. So why not just bundling it as an
extra or option with 4.0 ? If OpenStep is good, there's nothing to be feared,
we'll all migrate towards OpenStep. If it doesn't work out as planned, there's
still a way back at least.
Anyhow, let's see what happens to the WebObjects project, because that's where
there's an opportunity on some really innovative, object-oriented software !
It would be awesome to have an IB-like application (based upon a kit of portable
objects perhaps like HyperServer, HyperDocument etc. instead of Application,View
and so on) that you could use to build interactive web-servers, and where you
could "plug in" custom Objective C "target/action methods" as easily as in IB...

My image is a palettized image.
Questions:
a) Are there quick ways to get a palettized image to the screen?
b) If not, what is the quickest way to get an image which has been formatted
to the destination window depth to the screen? (I can write a routine which
will convert the palette into true color...).
I seem to remember that there were some issues of what type of format the
data should be (planar or not?), on what memory boundaries it should be
(quad boundary?), and what the number of bytes per row should be. Also,
wasn't there something about what pixel you should start writing to?
This is all hazy in my memory, and I'd appreciate some pointers to the

I think the original design decision was performance motivated. There are a
lot of non-opaque views, and having them all display from ancestor and having
it be efficient is a lot of extra work.

In OpenStep this is the way it works.

If (2) is bogged down in the details, look at possible ways to
improve (1). The only problem with (1) is that you don't want to
update the inspector if it's not visible. That's easy to solve
with two methods.
-[Window isVisible]
You can use this method to tell whether the inspector window is open. Code Snippet:
-updateInspector;
{
if (![[someUIObject window] isVisible) return self;
[someUIObject setStringValue:blah];
return self;
}
Also, if your inspector is multi-pane, you probably want to only
update the visible inspector. Only when the user changes to another
pane should you update the non-visible pane.
If that's not possible, you could code using the second method:
-[View getVisibleRect:]
This method takes a passed reference to a rectangle, and fills it
with the amount of the view that is visible. It also returns NO
if the element is outside the bounds of the window.

HI,
I am trying to check for a change of display values of a textField. So
I created a delegate for that, and I have used the textDidChange:textfield
method. This only works if there is a user interactio; that is if I change
the value in the textField manually. The value itself changes dynamically by
another process that writes to thextfield.
Any ideas on how to accomplish that will be greatly appreciated.
Thank you.

Carl,
I have done this and now, NcFTP does not give me the "floating
exception", but compiles without warning, and even executes. But upon
execution, I cannot page files and itr craps out on me suddenly. If you
have it, please upload it to ftp.orst.edu or any of the other NeXT archives.

This is from the original documentation:
******** Disclaimer ********
The General Cartographic Transformation Package (GCTP) is a system of
software
routines designed to permit the transformation of coordinate pairs from one
map projection to another. The GCTP is the standard computer software used
by
the National Mapping Division for map projection computations.
Because of requirements internal to the EROS Data Center, the GCTP software
was converted from FORTRAN to the C programming language, and several new
projections were added. During the conversion process, the software was
tested on Data General, SUN, and Silicon Graphics UNIX systems. In
addition,
the software has also been verified against the current National Mapping
Division (NMD) GCTP software. This new version, GCTPc, is being made
available informally on a 'user-beware' basis. EDC assumes no
responsibility
for the accuracy of the routines in this package.
Because of decreasing budgets and impacts on software development staff,
EDC will not be responsible for supporting this software package. The
user is responsible for using the package correctly. A set of validation
data is provided so that each user/facility may perform its' own testing
of the programs. A description of this data set and instructions for its
use are in the test/README file. EDC will welcome any questions, comments,
or suggestions, and will respond on a time-available basis based on our
interests and requirements. Communications concerning the GCTPc package
may be directed to this email address:
gctpc@edcserver1.cr.usgs.gov
The GCTPc Directory Structure is as follows:
gctpc
- README
- Announce.txt contains information on retrieving and installing
GCTPc
gctpc/doc:
- Documentation for GCTPc
gctpc/source:
- Code for the GCTPc library. A Makefile exists that has been
tested on Data General, SUN, and Silicon Graphics systems.
gctpc/test:
- Test procedures
Note: README files contain more information on each individual
directory.
Periodic updates and corrections will be put in this directory for access
by the science community. Descriptions of these updates will be added to
this file.

This is a complete printout of my stty manual page.
I am starting to not trust my man pages :-(
I did a 3.2 to 3.3 upgrade and I will check on the 3.3 CDRom.

NAME
stty - set terminal options
SYNOPSIS
stty [ option ... ]
DESCRIPTION
Stty sets certain I/O options on the current output termi-
nal, placing its output on the diagnostic output. With no
argument, it reports the speed of the terminal and the set-
tings of the options which are different from their
defaults. Use of one of the following options modifies the
output as described:
all All normally used option settings are reported.
everything
Everything stty knows about is printed.
speed The terminal speed alone is printed on the stan-
dard output.
size The terminal (window) sizes are printed on the
standard output, first rows and then columns.
The option strings are selected from the following
set:
even allow even parity input
-even disallow even parity input
odd allow odd parity input
-odd disallow odd parity input
raw raw mode input (no input processing (erase, kill,
interrupt, ...); parity bit passed back)
-raw negate raw mode
cooked same as `-raw'
cbreak make each character available to read(2) as
received; no erase and kill processing, but all
other processing (interrupt, suspend, ...) is per-
formed
-cbreak make characters available to read only when new-
line is received
-nl allow carriage return for new-line, and output
CR-LF for carriage return or new-line
nl accept only new-line to end lines
echo echo back every character typed
-echo do not echo characters
lcase map upper case to lower case
-lcase do not map case
tandem enable flow control, so that the system sends out
the stop character when its internal queue is in
danger of overflowing on input, and sends the
start character when it is ready to accept further
input
-tandem disable flow control
-tabs replace tabs by spaces when printing
tabs preserve tabs
ek set erase and kill characters to # and @
For the following commands which take a character argument
c, you may also specify c as the ``u'' or ``undef'', to set
the value to be undefined. A value of ``^x'', a 2 character
sequence, is also interpreted as a control character, with
``^?'' representing delete.
erase c set erase character to c (default `#', but often
reset to ^H.)
kill c set kill character to c (default `@', but often
reset to ^U.)
intr c set interrupt character to c (default DEL or ^?
(delete), but often reset to ^C.)
quit c set quit character to c (default control \.)
start c set start character to c (default control Q.)
stop c set stop character to c (default control S.)
eof c set end of file character to c (default control
D.)
brk c set break character to c (default undefined.) This
character is an additional character causing
wakeup.
cr0 cr1 cr2 cr3
select style of delay for carriage return (see
ioctl(2))
nl0 nl1 nl2 nl3
select style of delay for linefeed
tab0 tab1 tab2 tab3
select style of delay for tab
ff0 ff1 select style of delay for form feed
bs0 bs1 select style of delay for backspace
tty33 set all modes suitable for the Teletype Corpora-
tion Model 33 terminal.
tty37 set all modes suitable for the Teletype Corpora-
tion Model 37 terminal.
vt05 set all modes suitable for Digital Equipment Corp.
VT05 terminal
dec set all modes suitable for Digital Equipment Corp.
operating systems users; (erase, kill, and inter-
rupt characters to ^?, ^U, and ^C, decctlq and
``newcrt''.)
tn300 set all modes suitable for a General Electric Ter-
miNet 300
ti700 set all modes suitable for Texas Instruments 700
series terminal
tek set all modes suitable for Tektronix 4014 terminal
0 hang up phone line immediately
50 75 110 134 150 200 300 600 1200 1800 2400 4800 9600 exta extb
Set terminal baud rate to the number given, if
possible. (These are the speeds supported by the
DH-11 interface).
rows n The terminal size is recorded as having n rows.
columns n The terminal size is recorded as having n columns.
cols n is an alias for columns.
A teletype driver which supports the job control processing
of csh(1) and more functionality than the basic driver is
fully described in tty(4). The following options apply only
to it.
new Use new driver (switching flushes typeahead).
crt Set options for a CRT (crtbs, ctlecho and, if >=
1200 baud, crterase and crtkill.)
crtbs Echo backspaces on erase characters.
prterase For printing terminal echo erased characters back-
wards within ``\'' and ``/''.
crterase Wipe out erased characters with ``backspace-
space-backspace.''
-crterase Leave erased characters visible; just backspace.
crtkill Wipe out input on like kill ala crterase.
-crtkill Just echo line kill character and a newline on
line kill.
ctlecho Echo control characters as ``^x'' (and delete as
``^?''.) Print two backspaces following the EOT
character (control D).
-ctlecho Control characters echo as themselves; in cooked
mode EOT (control-D) is not echoed.
decctlq After output is suspended (normally by ^S), only a
start character (normally ^Q) will restart it.
This is compatible with DEC's vendor supplied sys-
tems.
-decctlq After output is suspended, any character typed
will restart it; the start character will restart
output without providing any input. (This is the
default.)
tostop Background jobs stop if they attempt terminal out-
put.
-tostop Output from background jobs to the terminal is
allowed.
tilde Convert ``~'' to ```'' on output (for Hazeltine
terminals).
-tilde Leave poor ``~'' alone.
flusho Output is being discarded usually because user hit
control O (internal state bit).
-flusho Output is not being discarded.
pendin Input is pending after a switch from cbreak to
cooked and will be re-input when a read becomes
pending or more input arrives (internal state
bit).
-pendin Input is not pending.
pass8 Passes all 8 bits through on input, in any mode.
-pass8 Strips the 0200 bit on input except in raw mode.
mdmbuf Start/stop output on carrier transitions (not
implemented).
-mdmbuf Return error if write attempted after carrier
drops.
litout Send output characters without any processing.
-litout Do normal output processing, inserting delays,
etc.
nohang Don't send hangup signal if carrier drops.
-nohang Send hangup signal to control process group when
carrier drops.
etxack Diablo style etx/ack handshaking (not imple-
mented).
The following special characters are applicable only to the
new teletype driver and are not normally changed.
susp c set suspend process character to c (default
control Z).
dsusp c set delayed suspend process character to c
(default control Y).
rprnt c set reprint line character to c (default control
R).
flush c set flush output character to c (default control
O).
werase c set word erase character to c (default control W).
lnext c set literal next character to c (default control
V).

Yesterday, I finaly got a message from our account-manager at informix that
the EOF-adapter is available. We will get one asap to test it out. He did
not yet know how much it will cost.
He also told me that version 2.0 of the adaptor will be released by Next
itself in Q1'96. Also other stuff of Informix (like E/SQL) will be ported
to Nextstep. So it seems Informix finaly accepted the Next-platform.

Subject: [HELP] How do I make my new(used) NeXT work?

Message-ID: <colen-1310951404320001@ip-pdx09-27.teleport.com>
Anyone who can help,
Please forgive my ignorance. Any help would be _extremely_ appreciated.
I've just aquired a Color NeXTstation.
When I boot, it says "Testing system...", opens a NeXT ROM monitor
2.4 (v65) window. Testings some more stuff (all the tests pass). Then
gives me a "NeXT>" prompt.
I figured "b sd" was the only intelligent option at this point. It
boots me into unix, in a "NeXT Mach Operating System" window. It tries to
set up network access, but fails (it's not connection to one yet). It
gives me a "#" prompt, from which I can list files. I can execute basic
unix commands. But I can't see to get any programs working.
How do I boot into the NeXT OS?
How do I get anything to display in color?
Why, whenever I try to execute most of the programs, does it just
access the HD, then freeze up? How can I make the programs run properly?
The person I bought this from said he has tried to install the latest
update to the NeXT OS, but wasn't able to get it working properly. I'm
not sure what he's done, or at what stage he left off.
What software should I have installed to make things work properly?
(I'm trapped in a well! PLEASE HELP ME!)

-display(::) could use -displayFromOpaqueAncestor::: directly, regardless. That
method would then do all the testing, and if the view was itself opaque, only a
few machine instructions would be ``wasted'', in any case a negligible amount
compared to the effort of drawing anything.

False negatives are harmless to display integrity, and if performance is
perceived to be problematic, the bit of each View can easily be set correctly.

I don't quite understand what you are saying here. Any object acting like a
View surely must subclass from View even if indirectly... Both a category, or a
poseAs view subclass will do the trick.

How odd. Why do you think any custom code written by the user (necessary to
circumvent the display integrity problems) will be more performant than a
general good solution?
Well, I've done some further testing. I switched off my solution described
below, and now not only was garbage left behind non-opaque Views (the problem
being discussed here), but subling Views were overwritten even without -[Window
useOptimizedDrawing:YES].
Question to Ali Ozer: What explanation can you give for that?
I've written a KBNS entry about this, which I've included below. If you're
interested, the currently published version of KBNS (``Known Bugs in NeXT
Software'') is 33.0, and can be found at:
ftp://ftp.cs.orst.edu/software/NeXT/documents/KBNS.33.0.rtf
Note that this must be a very controversial beast, because it's boycotted by
Mr. comp.sys.next.announce (Scott Anguish).

>>>>>
KBNS.33.1.032_o3.2o Specification bug for -display(FromOpaqueAncestor):::
Description: It is obvious from selector string length, and from the behaviour
of -display(::) and -update, that display::: is uniquely favoured among both
methods in the title. Yet it is also obvious that -display::: is not the right
method for non-opaque views (which is, unless a View declares itself opaque,
the default!): garbage can be left behind. It would have been better if
-display::: and -displayFromOpaqueAncestor::: would have been called
-incrementalDisplay::: (or somesuch) and -display::: (sic), respectively.
How to verify: I have verified by disassembling the m68k NS_3.2 NeXT_s code
that -display and -display:: are implemented exactly as documented:
-display{
return [self display:NULL :0 :NO];
}
-display:(const NXRect*)rects :(int)rectCount{
return [self display:rects :rectCount :NO];
}
Send any non-opaque View an -update or -display message (after it has changed),
to see what's the problem.
Urgency: Does no damage, immediately obvious, workaround possible.
Specification bug.
Confirmed: Raf_Schietekat (o3.2o, reported)
Workaround: Use an imposter that will poseAs View and redefine the following
methods:
@interface View_KBNS_33_1_032:View{}
-display;
-display:(const NXRect*)rects :(int)rectCount;
@end
@implementation View_KBNS_33_1_032
-display{
return [self displayFromOpaqueAncestor:NULL :0 :NO];
}
-display:(const NXRect*)rects :(int)rectCount{
return [self displayFromOpaqueAncestor:rects :rectCount :NO];
}
@end
That means only -display::: will do the non-obvious thing, but it is probably
important not to change it (if only for any internal use by the View
machinery).
Cure (for NeXT): See workaround (I don't think it will do any harm to make this
change?).
Report history: c.s.n.programmer 1995-10-11
Comment: Note that -displayFromOpaqueAncestor::: (I have not tested display:::)
seems also to preserve sibling Views that are in front of self (...even if
Window was sent -useOptimizedDrawing:YES!). That's nice... (Would be even
better if all this were clearly documented.) XXX But display::: does not
preserve sibling Views, even without [theWindow useOptimizedDrawing:YES]!: a
bug?

I'd say that you need to wire some notification mechanism into

That's my guess.

Does flock work under NS 3.2 and 3.3?
Is there any magic in flock that causes an implicit LOCK_UN when the
file descriptors are closed by an exit?
So far somebody on 3.3 is reporting that with an NFS mounted file
flock is unlocking ie. removing the lockfile implicitly... Where as
under NS 3.2 with a non-NFS mounted file it's not going that.
What's the scoop?

I had the same problem before the Foundation kit was introduced. Now I'm using the
NSNotifcationCenter class.
If you still have no access to the Foundation kit, MiscKit and IconKit both provide
classes (MiscAnnouncer and IKAnnouncer) partially capturing the Notification center
functionality.

Yes, you do. If you compile posix code and you are linking with posix
library you must specify the '-posix' flag in addition to -lposix.
Moreover the posix implementation under 3.2 is not good. Upgrade to 3.3 or
avoid compiling posix code at all.
I hope it helps you.

Message-ID: <45racm$s3b@sun0.urz.uni-heidelberg.de>
Hi, These are my top two strange problems for today ;-)
1) Somewhere in NeXT Answers (or Docs, or OpenStep Journal) there is a category:
@interface NSObject (NXConnectionDebugFix)
+ (const char *)name;
@end
@implementation NSObject (NXConnectionDebugFix)
+ (const char *)name
{
NSString *str = NSStringFromClass(self);
return [str cString];
}
@end
Well, NSStringFromClass is defined somewhere in Foundation, but the linker cannot
find the symbol for that function (this happens on my HP, and on SPARC). On another
HP it seams to work (the software versions are identical ... believe me!).
I implemented the function:
NSString *NSStringFromClass(Class aClass)
{
return [NSString stringWithCString:object_getClassName(aClass)];
}
.. and now the program runs happily on all three boxes (no redefined symbol!!!!).
Any explanations?
2)
I just got the following link warning on SPARC:
libtool: warning same member name (FoundationExtens) in output file used for input
files: sparc_obj/FoundationExtensions.o and: sparc_obj/FoundationExtensionsPrivate.o
(due to use of basename, truncation, blank padding or duplicate input files)
I was naive to think, that the SPARC and HP versions are identical ;-)

Add in the MiscKit (which has a simple file viewer example app) and
combine the two and it should be a breeze. The MiscKit handles the
file side of things nicely; the IconKit for the GUI side.
The MiscKit is at:

Message-ID: <45t0fu$pi@bsdi002.britain.eu.net>
I can't find ANY wysywyg html editors which handle full html2, let alone
the html3 draft. So I thought, perhaps I should try to write my own.
Looking at the text class as a starting place, I find I need to do several
things it can't handle -
1. Images with text wrapping round them.
2. Tiled graphics as a background to a document.
3. html3 figures - require text and images to overlay previous ones.
Reading the documentation, it looks like I would need to replace
NXScanALine() and NXDrawALine() in order to have any hope of implementing
the three features above. This does not look like a trivial task.
The class gives us the ability to change these functions, suggesting that
we might want to re-write thenm to re-position graphics, but then hides all
the paragraph formatting information from us behind a pointer to void, and
calls it i mplementation dependent. Should I even attempt it? Is there a
better approach?
Does anyone perhaps have source for a reference implementation of these
functions that I could work from?
Any help would be greatly appreciated (even if its "you'd be mad to try
because ...").

Hi all,
I have a
- NeXTstation Color runnning NS 3.2
- HP JetDirect Ex
- HP 850 C
and try to print but nothin happend.
I did the following:
1. Connect the computer and the HP JetDirect Ex via
BNC, T-connectors and termination resistances.
2. Connect the HP JetDirect Ex and the printer via parallel cabel
3. Add a new host with HostManager.app called "hp850c".
4. Delete all properties in NetInfoDomain "/hp850c" except
name -> hp850c
ip_address -> 131.234.172.201
en_address -> 8:0:9:62:2b:da
bootfile -> nothing.needed
5. Turn off and turn on computer, HP JetDirect Ex and printer
After that I am able to establish a "ping" connection from the computer
to the HP JetDirect Ex.
I am also able to print a statuspage on the printer by pressing the
"TEST"-button on the front side of the HP JetDircet Ex.
This page shows:
HOST NAME: 131.234.172.201
CONFIG BY: BOOTP
IP ADDRESS 131.234.172.201
SUBNET MASK: NOT SPECIFIED
DEF. GATEWAY: 0.0.0.0

SNMP GET CMTY NAME: ALL
SNMP SET CMTY NAME: NONE
BOOTP SERVER: 131.234.172.200
CONFIG FILE:
==============================
ETHERTALK STATUS: READY
So, I am sure form the "ping"-command that the connection from the
computer to the HP JetDirect EX is established, and I am sure from
the statuspage that the connection from the HP JetDirect Ex to the
printer is established.
Next I installed "JetPilot" and with the PrintManger.app a new printer
of type "JP HP DeskJet 850 C" with communication via "seriell port A"
(remember this is NS 3.2).
Afterwards I installed "JetDirectDriver.0.92" following the instructions
in the "INSTALLATION"-file.
Even if power is cycled to all components absolutely nothing happend if I
try to print testpages or other staff. No prints, no error messages, no
sparkle of a LED, no print job occur in the PrintManager panel.
Any help is welcome,
Alfred.

Well, yes, I do. I hate uploading binaries for generic UN*X packages, but
as a lot of people seem to have problems with this... The only problem is
that my local version uses ncurses and for some addled reason I forgot to
compile my libncurses fat, so I can currently only create NS/FIP binaries
of ncftp. And uploading thin binaries is not comme il faut. But the
next time I build ncurses and ncftp here, I'll be sure to upload binaries
for both to the archives.

Hiho !
I have a program using multiple threads. At one time I want to quit the
program and start another one using the UNIX exec(2) ( in this case execle )
system call. At that point I have all other remaining threads waiting in a :
thread_switch(THREAD_NULL,SWITCH_OPTION_WAIT,sometime);
mach call.
The exec just works fine, but the new program context has still the threads
waiting and whenever one of them awakes the program exits ( without getting a
unix signal(3C) ). So I finally found out about that behaviour and killed the
other threads in prior to the exec call.
My question now is, if that's the right behaviour or shouldn't a new program
begin with just one thread, cause it doesn't make any sense to me to keep them
running.
Btw. I killed the threads using the following hack ( knowing that running
threads don't fork ):
{
int i;
thread_array_t thread_list;
unsigned int thread_count;
task_threads(task_self(),&thread_list,&thread_count);
for(i=0;i<thread_count;i++)
{
if(thread_list[i]!=thread_self())
{
thread_suspend(thread_list[i]);
thread_abort(thread_list[i]);
thread_terminate(thread_list[i]);
}
}
}
what happens when a thread exit's before it get's aborted ? Do I just get a
!kern_success ?
Thanx for you time.

There's no quick way to get a palettized image directly to the display.
There are, however, ways to pump bitmaps in display format to the screen
quickly.
You'll want to use interleaved data, not planar. The data should match
the display format if possible. The two canonical 'good formats' for
doing this are 16 BPP RGBA and 32 BPP RGBA, with the alpha channel set to
be opaque, or all ones. Red data goes in the most significant nybble or
byte of each pixel as represented in a register, followed by green, then
blue, then all ones (0xF or 0xFF).
You'll want to put the data in a buffer with each scanline starting on a
quadword (64 bit) boundry, and padded to have a rowBytes count that is a
quadword multiple. Note that you don't actually have to have a quadword
multiple of pixels in each line. Padding is OK.
Construct an NXBitmapImageRep object pointing to your buffer, and put it
on the display using COPY or SOVER compositing as appropriate. (COPY is
faster, but you have to promise to set those alpha bits to be opaque!)
Assuming you already had the pixels in one of the formats described above,
just doing the quadword padding can get you a 30 speedup over unpadded
data on a 68040 NextStation Color.

I can't find ANY wysywyg html editors which handle full html2, let alone the html3 draft. So I thought, perhaps I should try to write my own.
Looking at the text class as a starting place, I find I need to do several things it can't handle -
1. Images with text wrapping round them.
2. Tiled graphics as a background to a document.
3. html3 figures - require text and images to overlay previous ones.
Reading the documentation, it looks like I would need to replace NXScanALine() and NXDrawALine() in order to have any hope of implementing the three features above. This does not look like a trivial task.
The class gives us the ability to change these functions, suggesting that we might want to re-write thenm to re-position graphics, but then hides all the paragraph formatting information from us behind a pointer to void, and calls it i mplementation dependent. Should I even attempt it? Is there a better approach?
Does anyone perhaps have source for a reference implementation of these functions that I could work from?
Any help would be greatly appreciated (even if its "you'd be mad to try because ...").

Subject: How to render images on NXBitmapImageRep
Hi, steppers.
I'm developping application that will be used for specific printer. So,
I can't use NEXTSTEP's original printing mechanism. Communication with
printer is based on ESC/Page which some printer maker specified
specification. Since the specification uses bitmap image, I must
convert EPS image into bitmap image for printing. But, I don't know how
to render Display PostScript image on NXBitmapImageRep. I wrote some
code for proving my thought, but all my efforts are in vain.
some code like this:
View *aView; // assume this exists.
NXBitmapImageRep *imRep; // assume this exists.
NXStream *epsStream = NXOpenMemory( NULL, 0, NX_READWRITE );
NXImage *epsImage;
NXPoint origin = { 0.0, 0.0 };
[aView getBounds:&bounds];
[aView copyPSCodeInside:&bounds to:epsStream];
epsImage = [[NXImage alloc] initFromStream:epsStream];
[epsImage lockFocusOn:imRep];
[epsImage composite:NX_SOVER to:&origin];
[epsImage unlockFocus];
NXCloseMemory( epsStream, NX_FREEBUFFER );
// here, imRep vapored!!
Perhaps, NXCacheImageRep will be candidated for imaging use, but I
don't know how to make NXCacheImageRep into NXBitmapImageRep. Or, I
make a totally misunderstanding about rendering DPS.

termination get "floating exeception" before returning to the shell or

the PD package 'SLiRP' (a freeware redoing of the TIA program that
does psuedo IP SLIP dynamically) which seems to make great use of
the POSIX routines (only way it will compile). Here is a 'gdb'

or management skills.
You must have a very strong NeXT development background, preferably in a
medium to large development environment. The group is planning to go with
OPENSTEP in the next six months, so some exposure to Windows NT would be a
big plus.
You must also have some management experience, preferably with 4 to 10
people reporting to you or under your supervision.
The renumeration package consists of an excellent base salary, plus bonus,

EPUBLISHER: your manual writer
Advanced Control Data introduces EPUBLISHER, your electronic manual writer
for Windows.
The idea:
EPUBLISHER, a professional editor/drawer/painter program for Windows
(like CorelDRAW,Pagemaker, Ventura Publisher, QuarkXPRESS), allows you
to create documents with fonts, drawings, colors, but unlike conventional
desktop publishing packages, Epublisher generates a very special output:
a very short ASCII command set. The length of a full color screen
is less than 1000 Bytes, so a full 1000 screen size manual with jumps,
graphics, and fonts is less than 1MByte.
On the client side, (WWW browsers, or your program manual on disk, etc.)
users use a free viewer, EPUBVIEW, to execute the commands generated by
EPUBLISHER.
In programming terms: EPUBVIEW is a graphical interpreter.
This unique technology allows you to generate many documents with full
desktop publishing features and allows you to send them over the wires within
seconds or if you write a manual, it occupies only a few kilobytes on your
floppy disk that you distribute.
The screen oriented output offers you new features:
* inserting buttons and icons into your document where readers can click and
jump,just like in an online service
Your manual is practically a small BBS engine on a floppy disk.
* using colors for coding text in your document is a new feature that has
just been introduced and that has never been possible before.
Example for color coding: you can build up your document in red color
for main text, blue for comments to go along with the document, and green for
headings and titles. users can extract text of any color from your document
and save it in a new file.

Sorry if this an extremely simple question but as I am just starting

I'm writing a small program that will take a selection from OmniWeb,
do a bit of processing on it and depending upon the result get OmniWeb
to load a new URL. So what I need to do is to get the selection - for
which I presume I use one of the NS pasteboards - then I need to get
the current URL from OmniWeb.
So how do i get the current URL out of OmniWeb, is there some object
that I can just have a look at, a function that can be called, or is

Well, to add to this topic: ncftp 2.x has two modes, a 'visual',
full-screen mode, and the normal line mode, as known from ncftp
1.9x. If you configure and compile ncftp in the usual manner on
NEXTSTEP, it's unable to use visual mode (AFAIK), since you need a
decent curses package for visual mode (which NEXTSTEP lacks).
Then, you could try and get ncurses (1.9.5 is the most recent). Sadly,
ncurses 1.9.x compiles for NEXTSTEP only with -posix. Therefore any
application which will be linked against libncurses.a has to be
compiled with -posix, too. Therefore you have to compile ncftp with
-posix if you want visual mode.
IMHO the best would be to port ncurses 1.9.x over to generic NEXTSTEP
(i.e. without posix), as the old ncurses 1.8 on orst and peanuts was.
Or am I wrong ?

Greetings,
We are moving some of our products to PDO, and are having some trouble
building libraries. After changing 'libtool' to 'ar' in library.make,
the libraries will build, but each subproject gets built multiple
times, the number of builds of each increasing with the total number
of subprojects.
If anyone has worked around this problem, we'd very much like to hear
from you.
Thanks in advance,

Create a custom printcap entry for the printer, and add a filter to the
printcap.
The filter can be as simple as:
#!/bin/csh
echo your-escape sequence here
cat -

Greetings,
Does anyone have an etags (ctags for emacs) that works for Objective C.
The etags that shipped with emacs 19.28 works partially, but has no
explicit support for Objective C, so it can not handle methods that do
not have parentheses. I would be partially satisfied if etags would
index only up to the first colon in methods that take arguments, since
it might be hard to parse the remainder of the method.

In the past I have been using a function called realpath. There used to be a
manpage, but that seems to have vanished with 3.3. There was never a prototype,
so you would have to write one yourself:
// the following prototyp is missing in <sys/param.h>:
char *realpath(char *file_name,char *resolved_name);
Has been working from 2.1 to 3.3.

And add in the free source for some free dock extender (e.g. Fiend.1.0)

I really love the MiscKit and the IconKit.

I would suggest that you take a look at the MiscKit. The File classes
might either already include that feature (does it Todd ?) or it should be
a good place to include it.
The filesystem tells you...and by checking those inode entries you should
be able to compare them for identity. With softlinks you should get an
entry in on of those strange UNIX-C strucutres (don't we ?)
OPENSTEP 4.0 will (as we have been told at ObjectWorld) include NeXTs
currently private Filesystem classes. Those seem to know how to deal with
sym-links etc.pp. (You find out if you open a file from ProjectBuilder;
every file will be opened by the absolute path...and not by the one you
would extect it to)

Yeap.. I was wondering about that too. Since the view know if it is opaque
or not (at least we can tell him).
I played with that and found it strange too. The docu gives no clue why
display should work differently.

Not only ISV seem to have used the 3DKit quitely...but different
scientific applications use it too.
But we have to agree on the one side:
- slow realtime 3D is not very useful -> 3D hardware necessary when
we come to a really professional level.
- NeXT won't sell too many new releases because of incredible fast
3D...at least not at the moment. And 3D optimization takes a lot
of work...especially if they want to get QuickRM with a hardware
driver layer etc.
I (we) hope that NeXT will continue to at least keep the 3DKit at the
current level..and will really move it to OPENSTEP 4.0.
Its nice to see that Wave takes the time to work on prman.
No matter what happens. The GNU 3DKit will be developed in parallel
anyway. You should get OpenGL for NeXTSTEP...and the 3DKit for all the
other OPENSTEP platforms. The RenderMan spec is an interesting 3D
Postscript an we want to keep it alive.
If NeXT decides to drop the 3DKit then we would like to see a
"MusicKit"solution.
Wave was completely right...tell NeXT that you care about the
3DKit/RenderMan.

We will get it from our accountmanager at Informix Netherlands. He went all
the way to the top executives of Informix Europe and Informix USA to get
the adapter.
As I assume the adapter will not be free, your best bet will be to talk to
your own
contact at Informix France and press hard!
I understand that from release 2.0 of the Informix EOF-adapter, Next will
do the sales.
The adapter was originaly developed by Informix Germany by the way. No
wonder the people at Informix get confused themselves.
Good luck,

Hi!
I compiled NCFTP "2.2.1".
But when I start it, I get this error:

Has someone got ncftp 2.2.1 or newer running on NEXTSTEP?
If yes, how?

(Note that my mail relay was down---full file system---during the weekend, so
any mail in or out may have been lost, possibly without a trace. My
c.s.n.programmer digests were lost that way, and therefore any message anyone
posted in this thread. My previous contribution was a reply to Steve James and
Ali Ozer, which may or may not have got through, I don't know: tell me if it
didn't.)
I want to correct something I said. If you send a View
-displayFromOpaqueAncestor:::, the sibling Views are *not* automatically
displayed as needed. This is just if the receiving View does not declare itself
opaque (the default is not opaque), so that the first opaque ancestor View does
a -display::: (I presume), and it has nothing to do with -[Window
useOptimizedDrawing:] until that -display::: (again, I presume).
My problem is now that -useOptimizedDrawing: state (no method for querying) is
apparently fixed to YES, even if you send -useOptimizedDrawing:NO. I mean, the
documentation says that this is about displaying sibling Views in the correct
order, but there is no difference (display::: never respects sibling Views).
Surely this can't be just for a display of the whole Window (what optimisation
would come from a reorganisation of which View is displayed first?)? Has anyone
ever seen any difference when setting this state in a particular way?
Is this a bug? I don't feel like disassembling that much of the AppKit to find
out what's going on. Ali Ozer?

Message-ID: <463ins$se7@fnnews.fnal.gov>
I know that NeXTStep SCSI disk performance is pretty bad since it does not
use Synchronous operation of todays controller cards and drives. I was wondering
if IDE or EIDE disk performance under NextStep is any better. I know that (E)IDE
is bad for having multiple devices being accessed but if you just have one
hard drive and a SCSI CDROM then you won't be experinceing these problems. I
also know that SCSI can do multiple commands at once while IDE cannot so in
that respect SCSI is better but I think asynchronous only operation under
NextStep cancles that benefit out with respect to IDE. So I'm wondering if
anyone has done any disk performance testing with DriverPerformance.app or
nwbench.app and what kind of results they have gotton for (E)IDE and SCSI.
I'm using an Adaptec 154x compatible VLB controller and since Next has released
the driver source for this controller, I was wondering if it would be
possible to modify it to work synchronously and and perform better. Or is
this a kernel level/file system problem and there really isn't much hope.
As a reference, I have a 500 meg Seagate ST3600N drive and can do about
500K/sec reads and writes to it using my controller. I've done other tests
on the driver under DOS and have gotton scores ranging from 1 to 2 megabytes/sec
under various sequential and random tests.
Thanks for any info or ideas..

When using CVS in team projects how do people keep both the PB.project
and Makefile in sync? Unfortunately, you get people who decide to edit
the Makefile but forget to check in the PB.project which reflects the
changes or sometimes visa versa.
I'm wondering how feasible it is to .cvsignore Makefiles altogether
and devise a tool that generates Makefiles from PB.projects when each
release is built both final and on going.
A serious problem can arise when these two files are out of
sync. Particularly when the Makefile is correct and the PB.project
isn't. The next developer to add resources to a project is going to
generate a new Makefile from the old incorrectly configured
PB.project. The point being that an out of sync PB.project can go
undetected for quite some time whilst the Makefile is correct. Let's
assume that everybody is generating new Makefiles when the Project is
saved in PB but in some cases builders build from the command line
rather than via Project Builder. It's inconvientent to require that
builders go through the project sub-project at a time and save in PB.
Of course this won't trap incorrectly configured PB.projects but the
aim here is the become aware of problems as soon as they are
introduced rather than later in the life of the project.
I believe this is a common problem when using version control systems
and I'd like to hear about how you've solved it or at least minimized
the risk involved.

Organization: Organization Resources Counselors, Inc.
Date: Thu, 19 Oct 1995 14:30:54 GMT
We have a problem with controlling a remote printer here. The current
setup is analogous to the NEXTSTEP boxes printing to a printer hanging off
a non-NEXTSTEP machine (I'll describe the exact setup at the posts end if
details are what you want). We have a PPD file for the printer and it
allows us to select cool things like double sided printing etc. Setting
these options and printing does nothing. I would guess the PPD was bogus
but if you use the Print Panel's save "PostScript For Chosen Printer"
option and then print that file all the options work.
In the NEXTSTEP 3.2 release notes there is a comment that addresses this:
Reference 30117
Problem Process PostScript comments at host
Description Device-specific PostScript for setting resolution,
page size, etc. is included in a job at print time based on
information contained in a PPD file. This inclusion is normally
handled by the NeXT machine to which the printer is directly
connected (the print server).
In Release 3.1, if you put a property called "_finalform" in the
printer entry, the PostScript inclusion process is handled by the
machine submitting the print job for spooling.
Reading this I added the "_finalform" property but this made no
difference. Has this option gone away since 3.1? Any ideas? Anybody doing
this?
EXACT SETUP
The printer is actually a rather spastic printer and doesn't support any
UNIX style of queuing. You can FTP jobs to it however and query its ready
status so the vendor provided a program that submits a job and waits for
its completion to return. So we use this as the input filter in a local
printcap entry and remote entries refer to that machine. So the remote
printer entry is identical to any normal remote entry. Here are the two
printcap entries:
# Remote entry in NetInfo's / domain
Lionheart: \
:sd=/usr/spool/NeXT/Lionheart:rm=seaside:_finalform: \
:rp=Local_Lionheart:lp=:ty=KODAK 1392 Model 44: \
:note=KODAK lionheart in Printer Room:lo=lock:
# Local entry on machine seaside in its Netinfo
Local_Lionheart: \
:lp=/dev/null:if=/usr/local/etc/iprsend.if: \
:sd=/usr/spool/NeXT/Local_Lionheart:lo=lock: \
:ty=KODAK 1392 Model 44: \
:note=Postscript Printer in Printing Room: \
:mx#0:_finalform:
I put the _finalform in both places in desperation it really based on
NeXT's note should only be in the remote entry. Note the local entry uses
the input filter to fire off "iprsend.if" which is a script calling a
program that actually ships off the PostScript and waits on completion.

I think one way to minimize the risk with this is to use commitinfo to
ensure whenever PB.project is committed that Makefile is too and
vica-versa. If you make a change to a PB.project then a change should
occur to the Makefile when you save in Project Builder (I say should
implying that that's the way PB should be configured in Preferences)
So you could just reject any commits that attempt to commit only one
of these files.

Umm, the "ScrollView" you get from the TextViews pallette is a Text object
within a ScrollView, not a ScrollView. If you want to put something in a
ScrollView in InterfaceBuilder you must use the
Format->Group->Group in ScrollView
menu entry.
You can then set which Scrollers are visible in the application
initialisation with
[scrollView setVertScrollerRequired:NO];

Subject: Re: -[View displayFromOpaqueAncestor:::]
Cc: Ali_Ozer@NeXT.com
Well, let's tame this beast.
Start of digression:
Part of the charm of NEXTSTEP is the intellectual challenges that it poses. You
see something that seems strange, you think a bit about it, you come up with
something better, and hey! there is that gratifying feeling of ``I can do this
too!''.
Well, actually, you think a lot about it. You think that there must be
something wrong with your judgement, because surely NeXT has designed this from
rich expertise and experience? You start looking at the big picture, trying to
find the architectural lines, the invariants that were observed, because surely
NeXT hasn't just created some small and manageable core of beauty, only to
paste some incoherent extras on top of that? The documentation doesn't help you
here. And anyhow, once you come up with an idea that seems beneficial, NeXT is
going to ignore it completely. (How nice if NeXT would now try to prove I'm
mistaken about this.)
End of digression, back to the beast.
So, -display::: is actually -incrementalDisplay::: of sorts, and good for
internal use by the AppKit or for wizzards with special purposes (from TeX, a
``wizzard'' is someone who understands the code, except that NeXT's code is
proprietary). -display(::) should use -displayFromOpaqueAncestor::: instead
(the real display:::). That much we've got.
But this method isn't implemented correctly either, because it forgets about
sibling Views that may be in front of that opaque ancestor. In computer science
parlance, the View hierarchy is a tree, that is displayed in pre-order
(recursively, first self is drawn, then the subviews). Just draw a small tree
and label its nodes in preorder. Pick a node (the View being -update'd), go up
one or two steps (finding the opaque ancestor), and look where the nodes are
with a higher ordinal. Those are the tree rooted at the opaque ancestor, plus
the trees rooted in the right-hand siblings of that opaque ancestor. But
-displayFromOpaqueAncestor::: only -display:::'s its own subtree. Surely, the
``From'' in ``displayFromOpaqueAncestor'' should mean in the back-to-front
ordering of all the Views in a Window? The direct chain to self would also make
linguistic (not functional) sense, but not just that tree.
So, Ali Ozer, would you please tell us what -displayFromOpaqueAncestor::: now
does, so we can devise a nice cure? Off-hand, I would just do something like
this:
>>>>>
-displayFromOpaqueAncestor:(const NXRect *)rects :(int)rectCount :(BOOL)flag{
/*var*/
pView_t pView; /*opaque ancestor (searched once, then held constant)*/
id *ptr; unsigned num; /*opaque ancestor and its right-hand siblings*/
int i; /*used to step through rects and through a derived array*/
NXRect rects1[3],rects2[3]; /*see below*/
/*todo should consult Window's useOptimizedDrawing: status,
or better yet, maintain a flag that records whether there are any
right-hand siblings that intersect self's bounds (even if only one pixel)*/
for(pView=(pView_t)self;
(NULL!=pView)&&(!pView->vFlags.opaque);
pView=(pView_t)pView->superview);
if((NULL==pView)||(NULL==pView->superview)){
/*pView is now the opaque superview, if any. It should also have a
superview, to get access to siblings. If any of this is not available,
just give up.
todo Or maybe do [window display]?*/
return [super displayFromOpaqueAncestor:rects :rectCount :flag];
}
for(ptr =((List*)((pView_t)pView->superview)->subviews)->dataPtr,
num=((List*)((pView_t)pView->superview)->subviews)->numElements;
(0<num)&&(*ptr!=(id)pView);
++ptr,--num);
/*now ptr and num describe the array of Views that should be display:::'ed:
the opaque ancestor and its right-hand siblings*/
if(0<rectCount && (NULL!=rects)){
for(i=0;i<rectCount;++i) rects1[i]=rects[i];
}else{
rectCount=1;
rects1[0]=bounds;
}
for(i=0;i<rectCount;++i){
[pView->superview convertRect:&rects1[i] fromView:self];
}
[window disableFlushWindow];
/*NeXT could recycle -display:::'s code
and remove the flushWindow's from it instead of doing these things*/
for(;0<num;++ptr,--num){
/* Why is this test required, i.e., why doesn't -display::: test
itself whether it should draw anything at all?
(Evidence: Look at a non-Buffered Window, with clip flag NO.
Perhaps it does this if the clip flag is YES, but then
only source code inspection can indicate whether performance
is wasted.)

if(NXIntersectsRect(&((pView_t)(*ptr))->frame,&rects1[0])){
for(i=0;i<rectCount;++i){

}
[*ptr display:rects2 :(int)rectCount :YES];
/*todo the clips should not be distributed over the siblings*/
}
}
[window reenableFlushWindow];
[window flushWindowIfNeeded];
return self;
}
<<<<<
That seems to work, although there is still room for improvement (too much
clipping going on, and maybe replace opaque sibling displays with clips
instead).
Updating Nonretained windows (a different story altogether, I have a
KBNS.33.1.035 ready about that) is slightly improved now, but still has display
integrity problems, probably because it uses display::, which uses NO for the
clipFlag.
If a View is moved to a different position in the View hierarchy, the old
superview is not updated. Why is that not documented?
A fine mess. Seems someone should take a close look at that AppKit. Any
comments?

emacs for NS is good, but I have the following problem. When I set
the screen resolution to 1280 by 1024 and then start emacs I get the
following error 'Screen has an unknown visual class' and my .emacs file is
not read. This does not happen when I set the screen resolution to 1152

Does anyone know why this is happening?

Hi all.
Now NeXTSTEP 4.0 will have an intersting shelf where you can drop many
differnt Pasteboard types.
NS 4.0 will have some classes to work with users and hosts.
But will it have a generic pasteboardtype for addresses ?
Taligent has pushed the idea of people, things and places. Its not new.
Apple has introduced business card "drag-GUI-objects" some time ago.
Since NeXT is so much focues on big customers I just can't understand why
there is no generic "basic" pasteboard type for people-bussiness cards
etc.
One could just take a NSDictionary and stuff all the know entries into it
and let it archive on the pastboard. Then one only has to specify some
keys for the required or recommended data.
Some general icon for that would be cool too (I really like the taligent
idea....but Taligent will take 2 Years until it runs fast enough to really
use it..and then its C++...I don't wnat to use it)
If NeXT can't decide to kick out such a structure (IMHO they could....the
dilemma of all those different address formats which are used by the
system itself, does not reflect the eleganc of NeXTSTEP)
...why don't those programmers (PencilMeIn, SBook, Phone, Email apps,
etc.) get together and define a defacto standard ? It worked with the
WebURL stuff...why not with addresses and busines cards.
I know I asked that question about a year ago too....but nothing has
happened since then. I just can't give up that idea.

Why don't you post the code so we can take a look? For example, how are
you declaring your matrices, and what's in them (are they integers,
doubles, structures, etc)...?

NeXT's aready 90% of the way there. Look at Library/Addresses/-
Example.addresses. It contains a file called Addresses.table, which
seems to contain an array of dictionary-like things. If you
open Example.addresses as a Folder, you get a 'fake' File Viewer
which displays each entry as a rolodex card. If you drag a card onto
a Mail or Edit window, the person's information gets pasted in.
All NeXT has to do is break Addresses.table into separate files
for each record. OR make the pseudo-viewer capable of writing
the information into a file, which would be drag & droppable anywhere.

Does anyone know of a reasonable way to make the Text object draw
lines of text closer together? The lineHeight can be used to increase
the distance between lines, but it doesn't seem to work for decreasing
that distance. I'm looking for something simpler than subclassing and
overriding drawFunc, though if someone is willing to share some
example code I could make a run at it.

NS supports synchronous SCSI on selected drivers. Try the Adaptec 2940 which
comes in both VLB and PCI. However, if performance is what you are seeking,
you should be using PCI and not VESA local bus.

I know that NeXTStep SCSI disk performance is pretty bad since it does not
use Synchronous operation of todays controller cards and drives. I was wondering
if IDE or EIDE disk performance under NextStep is any better. I know that (E)IDE
is bad for having multiple devices being accessed but if you just have one
hard drive and a SCSI CDROM then you won't be experinceing these problems. I
also know that SCSI can do multiple commands at once while IDE cannot so in
that respect SCSI is better but I think asynchronous only operation under
NextStep cancles that benefit out with respect to IDE. So I'm wondering if
anyone has done any disk performance testing with DriverPerformance.app or
nwbench.app and what kind of results they have gotton for (E)IDE and SCSI.
I'm using an Adaptec 154x compatible VLB controller and since Next has released
the driver source for this controller, I was wondering if it would be
possible to modify it to work synchronously and and perform better. Or is
this a kernel level/file system problem and there really isn't much hope.
As a reference, I have a 500 meg Seagate ST3600N drive and can do about
500K/sec reads and writes to it using my controller. I've done other tests
on the driver under DOS and have gotton scores ranging from 1 to 2 megabytes/sec
under various sequential and random tests.
Thanks for any info or ideas..

#define NSDATE_TO_TIMET(NSDATE) \
((time_t)(floor([(NSDATE) timeIntervalSince1970])))
#define TIMET_TO_NSDATE(TIMET) \
[NSDate dateWithTimeIntervalSince1970:(NSTimeInterval)(TIMET)]
Or, if your Foundation is an older one that doesn't have those methods:
#define TimeIntervalSince1970 978307200.0L
#define NSDATE_TO_TIMET(NSDATE) \
((time_t)(floor([(NSDATE) timeIntervalSinceReferenceDate] +
TimeIntervalSince1970)))
#define TIMET_TO_NSDATE(TIMET) \
[NSDate dateWithTimeIntervalSinceReferenceDate: \
((NSTimeInterval)(TIMET) - TimeIntervalSince1970)]
Those floor()s are optional. Dates before 1970 produce negative time_t
which may produce incorrect results in some functions (or, might not).

The problem is not 1280x1024 resolution. The problem is that you are
running in 8-bit mode which didn't exist when Emacs.app 4.0 was released
years ago and hence confuses it. This (and many, many other problems)
was fixed in 4.1 which was released half a year ago. For that reason I
encourage everybody to upgrade to 4.1 as soon as possible. I really
don't want to hear that "unknown visual class" bug another time, if it
can at all be helped. :)

Hello,
Some time ago, I saw a version of the "Draw" app (in
/NextDeveloper/Demo/AppKit/Draw) that can be used by multiple users.
Does any of you know where I can get it? Is it still available?
Thanks for your help.

hello
I'm have begun to work with NS 3.3 and want to start programming small
apps. I know what's programming in C quite well and also of unix. But
I don't know how apps are managed under NS, as well as how the builder
works. NeXT and Addition Wesley have some books about it.
Any advices what to buy ???
thanks in advance

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

[from the document ftp://ftp.next.com/pub/NeXTanswers/1000_Help]
Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.
USING NEXTANSWERS BY FAX
To use NeXTanswers by fax, call (415) 780-3990 from a touch-tone phone and
follow the instructions. You'll be asked for your fax number, a number to
identify your fax (like your phone extension or office number), and the ID
numbers of the files you want. You can also request a list of available
files. When you finish entering the file numbers, end the call and the
files will be faxed to you.

Hi folX,
I try to bycopy an object (like a window) across a connection
but the econding/decoding scheme fails. The problem is that
a window knows its views and a view knows its window.
If the window encodes the view with a
[portal encodeObjectBycopy:view]
an the view also encode the window with a
[portal encodeObjectBycopy:window]
I get a loop, the portal is not recognizing that window is
an object (the root object) just being encoded. Why? I think
this should work like typedstreams. What's the right way to
bycopy an object with such nested objects?
ThanX in advance Timo

Date: 23 Oct 1995 19:03:07 GMT
Organization: University of Wisconsin, Madison
Message-ID: <46gotb$kqi@news.doit.wisc.edu>
I'm interested in properly using some of the envelope sizes defined in various
printer PPD files. How do I go about adding new entries into the PageLayout
panel so that the various envelope types are properly handled between the
program and various printers.
For example an HP_laserJet_4_plus has these paperTypes defined in it's ppd but
they do not show up in the PageLayoutPanel
*PaperDimension Comm10/Env Com-10: "297 684"
*PaperDimension Monarch/Env Monarch: "279 540"
*PaperDimension DL/Env DL: "312 624"
*PaperDimension C5/Env C5: "459 649"
*PaperDimension B5/Env ISO B5: "499 708"
I know I can get this kind of information about the printer through the
NXPrinter object, but I don't know how to make thes PaperTypes show up in the
PageLayout panel. I don't want to just set the type to other and just enter in
the proper page size, because other information like ImageableArea and where
the envelope is (center, left edge, right edge) is lost.
Thank You

Subject: setstrokeadjust and fill
Hello experts,
Suppose I have a diamond or ellipse that is to be filled with a light colour
(say, white) and to have a black border. That would be done as follows:
(construct path)
gsave
(set light colour)
fill
grestore
0 setgray
stroke
The result is to be shown on an NX_LTGRAY background. Now, for both
1-pixel-wide setstrokeadjust-true strokes (the default in NEXTSTEP), and 0-wide
setstrokeadjust-false strokes, some, or even many, white pixels are visible
outside the black border (quite conspicuously for someone with good vision and
on a MegaPixel).
The workaround is to switch setstrokeadjust to false, and to use
0.01-pixel-wide strokes. This gives a stroke whose blocks of pixels slightly
overlap instead of touching only diagonally, and surely, the escaped white
pixels are now covered completely. Of course, now it becomes necessary to draw
conditionally depending on the state of NXDrawingStatus, because such a fine
stroke on a printer would not look right.
Did I overlook anything? Have you encountered this as well? Can this be called
a (specification) bug, that fill's are not appropriately affected by
setstrokeadjust-true (but what about the 0-wide case)?

Message-ID: <46h8mj$onq@elaine19.Stanford.EDU>
Hi,
I'm running a NeXT Cube with the 3.2 OS, and I seem to be missing some
critical link libraries for ld. The libraries I seemed to be missing from
my /lib directory were crt0.o, gcr0.o, libsys_s.a, libsys_p.a. Another
computer here running 3.0 had the files I was looking for and I copied
them into my /lib directory. However, when I try to compile, I get errors
saying the .a files are out of date (which I figured might happen), and to
run ranlib to update it.
When I run ranlib on it, I get all these errors saying that "cputype is
zero (reserved value)".
So three questions,
first, is there something I should know about running ranlib, or is it
just not going to work with the 3.0 libraries.
second, if I can't get ranlib to update the 3.0 libraries, is there
ANYWHERE that I can get the 3.2 versions? (the people using this NeXT
before me aren't sure where I can it, or what happened to the libraries
(former administrator may have taken off))
Finally, I might be able to get a hold of the 3.3 libraries, would those
work on 3.2?
Thanks,
Patrick

Hello!
I wrote a program that using "rexec" to execute other hosts'

I can't get much more manuals about this call !! I used it
only with one page unix online manual!! I also read the STEVENS'
UNIX network programming, but not much more than the online manual.
When using, I always got "segmentation fault" after 5 hosts
spawned. Do you know what's the matter ?? Or where can I get
the detail manual. And I don't know why the first argument is a
double pointer? what is the format of the string set (or string)?
May it be my program's problem...

about Help not being available. Yeah, I already knew that :-) But what
does pressing a key equivalent (other than Command-?) have to do with
Help?
I thought I had broken something, but before delving into the problem,
I merely moved an old Help.store file into English.lproj, and now the
popUpMenu key equivalents work correctly!!
Can anyone explain this?

My Multi Billion $, Fortune 50 client, is currently searching for 10 NeXT
developers for a huge new project in the Chicago area.
You will be part of a new project team, responsible for the development of
new financial applications for company wide roll-out across America. These
mission critical applications will be built in a NeXTSTEP/OpenStep/Sybase
environment, and will include use of state-of-the-art object
methodologies, NeXT based tools, and run on 3 major platforms (Intel,
SunSparc/Solaris, WindowsNT).
Candidates must have a strong background in NeXTSTEP development, with
exposure to AppKit, Objective-C, EOF, Sybase/Oracle and any other NeXT
tools.
I would like to talk to candidates with a strong background in NeXT
development projects, who are also looking for a career opportunity in
NeXT development as a senior programmer or project leader.
Salaries are excellent, as well as, great benefits, a bonus, and
relocation if necessary.
Note: This client has only recently established a NeXT development group
in the Chicago area, and is not a bank or financial institution currently
known as a NeXT site in the Chicago area.

I have looking for a spreadsheet object that would be somewhat similar to

something like a table viewer. It would allow me to show text and tiff

Now the problem? I looked up some vendors from the Stepstone WEB page
and tried to contact them. It seems that the ones that claimed to have
something like this are out of business! Is NEXTSTEP third party business
that bad?
Any guru out there who can help in pointing out a vendor, or a public

I have a Next box running 3.0.

I think there is a general problem in NeXT's pipelining concept, too!
Ever tried this:
dump 0f /dev/rst0 vs. dump 0f - | compress >/dev/rst0
My P90 doesn't get much load by the compress tool (you even might try
cat!) but the output drops from 10MB to 2MB per minute for me!
dump internally works with threads, but I see no way to enlarge the
pipeline buffer.
Mybe I'm completely wrong, but as far as I remember redirecting the
output is implemented using the same pipelining mechanisms.

Boerny.

Every object in the hierarchy to be moved over the connection must
implement the NXTransport protocol. Every object that is not a leaf node
in the hierarchy must, in it's
encodeRemotelyFor:freeAfterEncoding:isBycopy: method, invoke this method
of subsidiary objects.
The 3.x AppKit doesn't implement NXTransport for it's Window and View
classes and subclasses, and in many cases, the classes won't work properly
when referring to proxy objects instead of actual View subclasses. (Think
about things like connections to the Window Server, and state kept in the
Window Server, outside of the object.)
Yes, it should work just like typed streams, but... The typed stream and
AppKit API predates distributed objects by a few years. D.O. is a more
recent addition to NEXTSTEP.

Add menu items dynamically at runtime without having to bother removing

Subject: Synchronous workspace file operations? How?
Hello,
I believe there was some discussion of the "options:" argument to the
NXWorkspaceRequestProtocol's "performFileOperation:..." method
recently, but I can't find it. I also have some related questions:
Basically, is there any way to get the workspace to perform an
operation _synchronously_ ?
The documentation hints that some operations are synchronous -- is
this just a characteristic of certain operations, or can I control
it?
I'd like to use the Workspace to perform file operations, in order to
start getting away from operating-system dependencies, but having
operations performed asynchronously is not always helpful.
In my case, I want to copy file X to directory Y. I first check
whether Y/X already exists and ask the user if they want to replace
it. If so, I ask workspace to delete the old X. Then I ask
workspace to copy X to directory Y. Finally, I open file Y/X for my
own processing.
Specific questions I need answers to:
1. Does anyone have a good solution for doing an ordered sequence of
file operations?
The only ideas I have at the moment are (a) to wait for a couple of
seconds after each operation (obviously a lousy approach) or (b) to
follow each operation by a loop which repeatedly examines the file
system to see if files exist or not (at least this should work, but
doesn't thrill me), or (c) to somehow wait for the
"app:fileOperationCompleted:" message from the Workspace, but I don't
see any good way to do this in the middle of a procedural operation.
Any ideas?
2. For planning toward the future, does anyone know if this sort of
thing is better-supported under OpenStep? How can I best shape my
code in order to make a smooth transition in the (relatively near)
future?
Thanks in advance,
Doug

Programatically add items to it? For example, one menu item per bundle in

Populate them at run-time, of course.
I have the same problem with DBTableView. As a convenience, I'd like to
drop one on a window in IB, and set it up for size, autosizing, etc., but
not have any vectors in it until I populate them at run-time.
Unfortunately, IB (or something) forces at least one vector to be present,
which makes for an (admittedly mildly) annoying special case when building
the vectors at run-time.

What a *patronising* attitude! Don't you think anyone deleting the last command
in a menu does so intentionally and for a purpose that is his/her good business
(maybe generating those commands programmatically, say, from a file that an
ordinary user can edit)?!
Why don't you throw out this misfeature and devote your attention and resources
to Software Quality Assurance instead. For starters, fetch KBNS (see
c.s.n.announce) for a list of InterfaceBuilder.app bugs (and suggestions).

If you're going to add menu items dynamically at runtime, why not just
add a submenu when you need to add the first menuCell? Seems
unnecessarily confusing to have an empty submenu for users to try to grok.

Well, they *appear* to work correctly, but in fact, the first time a
key equivalent is pressed, Help.store is read into memory, but no Help
panel is displayed, just a fair amount of disk activity and delay before
the popUpList is activated!!
Maybe this is a feature to accelerate the opening of the Help panel
when it is actually requested :-)

Try the following:
- appendText:(const char *)aString to:(Text *)theText
{
int endOfText = [theText textLength];
[theText setSel:endOfText :endOfText];
[theText replaceSel:aString];
[theText scrollSelToVisible];
return self;
}

It sounds like the problem is with your program.
The first argument is defined as 'char **ahost;' because the rexec
function may need to store the canonical hostname of the host
to which you are connecting. Here is a code fragment showing
the proper use of this command. You must make sure, that you
pass the address of a buffer that is not only writable, but is
large enough to store the longest name that the gethostbyname
function can handle.
#include <sys/param.h> /* MAXHOSTNAMELEN defined in here. */
. . .
. . .
char ahost[MAXHOSTNAMELEN+1];
strcpy(ahost, "host");
sockfd = rexec(&ahost, inport, user, passwd, cmd, fd2p);
If you look in the ahost buffer after the call, the hostname 'host'
may have been replace with the string 'host.foo.com' the standard
(canonical) hostname returned by the gethostbyname lookup.
Here's another
strcpy(ahost, "127.0.0.1");
sockfd = rexec(&ahost, inport, user, passwd, cmd, fd2p);
In this example the gethostbyname was passed a dotted IP address
rather than a name. The contents of the buffer ahost has now been
overwritten by the name 'localhost' which is the name of the loopback
address 127.0.0.1.
Does the man page for rexec make more sense to you now?

Keywords: next apm power management bios portable computer advanced
Ok, so Next claims to have power management in NS 3.3. Some of the glossy
type documents (e.g. "What's new in 3.3") say so, and the little battery
monitor and preferences module running on the portable here seem to back up
this claim. And, while booting, the portable even says "Power Management
Enabled". Nifty.
However, I cannot find ANY technical documentation on this anywhere. I
would really like to improve the power management functions of NS on the
Thinkpad I have running here (like having a working suspend and hibernate
mode). In fact, if I accomplished this, it might benefit everyone else out
using the thinkpad as well. I have even gone so far as to order IBM's
technical specifications book (red-book) for the Thinkpad.
But all this does me little good right now because I have no idea how to
interface with NeXT's implementation of power management. I don't even know
if it's at the kernel level (it probably is), or in some driver that gets
loaded early on. I would guess that there are some classes somewhere
dealing with power management.
Adding to the mystery, in /NextDeveloper/Examples/DriverKit/AMDPCSCSIDriver,
I found references to a type called PMPowerManagementState, and an include
for aheader file <driverkit/IOPower.h>. However, I cannot locate any such
header file on my system.
If anyone has any clue as to the details of NS 3.3's power management, or
where I could find this mysterious header file (IOPower.h) your help would
be appreciated.

I have a class that other classes in the subdirectories
inherit from. When I change the superclass I'ld like for the
classes that inherit from it to recompile. I did a make depend
and it properly created the Makefile.dependencies in the bundles
as it should, but they don't work. Touching a file will not
cause the dependents to recompile. Has anyone else experienced
this problem? Any idea how to get it work properly?
Here is an example of a Makefile.dependencies in one of the
bundles:
blah.o : ../fred.h
Changing fred.h does not cause blah to recompile:(

Hi,
Does any body know where I could find an example of how to write a

which I have and on a couple of Net Archive CDs but can find only
examples about 'loadable kernel servers' - as drivers.
This area does not appear to be documented in NeXTdeveloper at all.
There is 1 header file with some info about loadable_fs but would
still like an example to see how it all goes together.

I, too, would like some more information on this. On my laptop, the power
management option is started, but the battery indicator icon doesn't
operate. It is also not clear what else it should do, apart from display
"Power Management enabled" at startup (which may be its sole function :-).

Because I might know that there _will_ be menu items there when the
application is running (like actions loaded from bundles... ;-)
Of course it's just plain laziness, but then again that's what IB's
there for (avoiding unnecessary work...)

Do the guts of rexec require this buffer to hang around until the remote

Does this mean I don't get to flame you? Darn. :-)
In any case, I'd like to clarify what I said earlier, so there won't be
any (more) misunderstanding.
I understand that someone might want to add menu items to a menu at run
time, but I'm not quite sure I see that as a good reason to have an empty
menu in the nib file. A menu with no items in it is something the user
should *never* have to deal with. It just plain looks bad, and it's
rather confusing.
You're going to have to to enable/disable the main menu item that calls up
that submenu, so you have to special-case the first addition to the
submenu anyway. What's the problem with simply creating the submenu at
that point, or changing the title/target of the first menucell when you
enable the menu?
Or am I missing something? Maybe I should just go write an app that does
this, and see what issues come up...
p.s. Thanks to everybody who sent me mail explaining the other side of the
argument.

Hello,
I've been working with tapes a bit lately, on a mess-o-platforms
(SUN,HP,IBM,DEC,NeXT,and more),
and I'd like to get a reality check on an idea I have. I realize that
tapes, like modems, were surely created by the devil, causing endless
suffering. Still, I can't help but wonder how tapes could be integrated
into the NEXTSTEP/OpenStep desktop. Could the device files associated
with a SCSI tape unit be symbolically linked to some file in, say, a /tape
directory, that had names describing the device files characteristics, and
a suffix that would be associated with a tape icon? When a tape mount was
sensed, a tape icon would appear in the workspace. The information in the
file name might be used by any utility or application using tape, which
could also be associated with the suffix.
A tape mount would need to be auto-detected, like SCSI CD's. Volume
management is always a sticky issue, best left to the utility/application
software. It would be nice to display any tape label with the icon on the
workspace, though.
I'm sure there are plenty of things I haven't thought of, but is there a
reason something like this can't or shouldn't be done?

Alan Frabutt (amf@ntt.com)

Some sort of direct interface to a tar archive in the tape? The former would
be super-painfully-slow ("damn....clicked on the tape...guess I might as well
go get lunch"), but the latter might be interresting.

Yes, I actually have held, in my hands, one of the infamous HP reverse
wound 1/4" cartridge tapes. Value Added indeed :) .
Still, the most evil tape related thing I'm dealing with now is trying to
read a tar tape from an IBM AIX box. I can read it on an exabyte attached
to a NeXTStation, but the customer can't read it on _their_ IBM AIX
box...!?

The idea, such as it is, is to have some kind of interface object, like a
workspace icon, showing a tape has been mounted. I can't see treating it
as a filesystem, wouldn't the entire tape have to be read and interpreted
(and any subsequent tapes if files spanned volumes) to present it so?
An inspector panel bundle might interrogate the device file to provide
some kind of information... the file symbolically linked to {/dev/rst0}
with the (.tape ?) suffix whose icon would appear in the workspace could
be double clicked, and an application associated with ".tape" file types
would launch and try to figure out what was on the tape. The complicated
and annoying issues of dealing with tape blocksizes, densities, etc. kick
in about now...
It just seems to me that something should happen in the interface when a
tape is loaded. A scheme to at least wedge the tape into the interface
could provide enough of a framework to also integrate all the clever tools
many people have written to deal with tapes.

There was a posting in comp.sources.misc (or .unix my memory is a bit vague) from a guy
who did a NFS Server on top of the tapedriver on a SYSV machine. The whole thing was
posted as wormdat.shar. The autor was jhpb@sarto.gaithersburg.md.us (Joseph H
Buehler) posted Sat, 10 Dec 1994.
Please note that this does not work on NeXTSTEP yet, I post it only to point out a possible
working solution for accessing the Tape device without much hazzle. Needless to say that
using a similar solution one could access a remove drive just as normal NFS exported
filesystem.
Here a bit from the readme, sorry for the bad formatting but lazy as I am I took this out of
the shar file:
-------
wormdat - NFS mountable filesystem using RAM or WangDAT 2000 tape drive
SYNOPSIS
wormdat [-d <string>] [-p <int>] [-r] [-D <string>] [-R] [-T]
DESCRIPTION
The wormdat program is an NFS server daemon that supports two
different filesystem implementations. One is a RAM filesystem, the
other is a WangDAT 2000 tape drive filesystem. Both have semantics
similar to the UFS filesystem, including symbolic links and long file
names.
Both filesystems allocate their internal data structures dynamically,
so maximum filesystem size is not set when the filesystem is created,
unlike typical disk filesystems.
The RAM filesystem can be loaded from and unloaded to disk. A
user-supplied shell script (F<@WORMDATUNLOADDIR@/load_unload.sh>) can
be executed at various points in the load or unload process to perform
operations like compression or encryption on the data to be loaded or
unloaded.
The DAT filesystem uses a DAT tape formatted in two partitions. The
primary partition is used to store file data blocks, the secondary
partition is used to store all other data, including directory
information, indirect blocks and inodes. The secondary partition is
only accessed during mount/unmount operations. Tape blocks cannot be
randomly rewritten, so a block mapping scheme is used to allow file
blocks to be rewritten; modified and newly-created blocks are written
to the end of the tape. However, a side-effect of this is that the
tape can eventually fill up. Inode and directory information is
stored in the daemon's memory space during normal operation and
changes to these items do not cause tape accesses. A sophisticated
cache is used to minimize tape motion and ensure that blocks are
written to tape in optimal sequential read access order.
The load and unload formats for both filesystems use DR to ensure
machine independent load/unload data.
When a RAM filesystem is provided by the daemon, the load/unload shell
script F<@WORMDATUNLOADDIR@/load_unload.sh>, if it exists, is executed
by the wormdat daemon just before and just after a mount or unmount
operation. The first argument to the script is B<preload>,
B<preunload>, B<postload> or B<postunload>, depending on the phase of
the operation in progress. The second argument is the name of the
data file (no directory part) used in the mount/unmount operation.
The current directory is the F<@WORMDATUNLOADDIR@> directory when the
script runs. The preload code in the script should result in the
creation of a file named as per the second argument, so the daemon can
load it. The postload code should do any cleanup required after the
daemon completes the mount operation. The preunload code should do
any preparation required before the daemon unmounts the RAM
filesystem. The postunload code should perform any processing desired
on the file (named according to the second argument) the daemon
created during the unmount operation.
....
BUGS
While running the daemon in DAT mode, SCSI check conditions cause the
pass-through driver to hang, requiring a reboot to regain access to
the tape drive. This is generally only a problem if an unrecoverable
tape read or write error is encountered, or if the daemon is started
without a tape in the drive, or the tape is changed while the daemon
is running.
-----
I think something similar could be done in NeXTSTEP too. If anyone has interest in
bringing this to NeXTSTEP please let me know.
Bye

NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc

by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.
USING NEXTANSWERS BY FAX
To use NeXTanswers by fax, call (415) 780-3990 from a touch-tone phone and
follow the instructions. You'll be asked for your fax number, a number to
identify your fax (like your phone extension or office number), and the ID
numbers of the files you want. You can also request a list of available
files. When you finish entering the file numbers, end the call and the
files will be faxed to you.

Agreed - I already saw a potential problem using NK as a prefix (taken from my
company name, NiKA Software - luckily I already saw NS coming) and a public
domain kit that someone was referring to on the net which also used NK as a
prefix.

I know that NeXT keeps (kept?) a registry of file extensions for file packages,
which are more like to pose a problem since they effect all users of any given
combination of two apps, rather than developers who are sharing classes
(unfortunately). I never heard of any such registry of class name prefixes.

It appears that there is a trade-off to be made between using the common
convention of 2 char prefixes for brevity, and more characters (eg: "Misc") to
make uniqueness more likely moving forward (assuming we are going forward ;-).
Oh, well, that's one of the cons of a global class namespace. I'll stick with
two char's for my stuff and deal with collisions if they occur.

Take a look at the source for Opener.app. It's available from
ftp.cs.orst.edu in
/software/NeXT/sources/util/Opener_3.3_MAB_source.tar.gz. The binary
(quad-fat) is in /software/NeXT/binaries/util/Opener_3.3_MAB.tar.gz.
BTW, Opener understands .gz and all sorts of other filename extensions which
represent compressed/archived/encoded files. Perhaps Opener is what
you're looking for in the first place.

I started a little thread on 1995-02-18 (``Is anyone managing identifier
prefixes?'), but this didn't lead to much. In particular, in an off-Usenet
exchange with NeXT I offered to do the administration myself, to have the
database published through NeXTanswers. But NeXT was not interested; they
merely ``reserved all two and three letter uppercase prefixes'' (sic) for
themselves. To be completely honest, they wrote to me they would discuss the
problem. But then they went silent and did not reply to my subsequent messages.
And I wasn't even being unpolite... ;-) maybe a little too complicated with
regular expressions and what all. Perhaps my contact had left NeXT?
My offer stands. Just send me your requests.
As for Alex' CS and CX, those would be too greedy (bad style), but might be
allowed if the company is large enough and the code of sufficient volume
already. I would suggest two letters at least per company, to subdivide
internally ad libitum. Individuals and small companies should provide at least
three letters, preferably three initials. For example, I will use RJS for
myself, even though I ordinarily don't follow the (Anglo-Saxon?) custom of
mentioning a middle initial (and I have three of those, haha). If/when
conflicts arise, added digits will resolve them (the first character after the
prefix should not be a digit). Of course, this is just a workaround for a
fundamental problem, but we're stuck with that for the time being, so...
I should probably make the database available via ftp. Now what name should I
give it? Would Registering_Identifier_Prefixes.rtf be too long? What would be a
clear acronym (RIP, IP won't do)?

As I'm sure everyone knows, NeXTSTEP and NeXTSTEP related hiring
is at an all time high, due primarily to OpenStep and NeXTSTEP for
Windows/NT. Currently it's a programmers market, with more open
positions than qualified people to fill them. Many of these
positions are with companies just starting to get their feet wet
with NeXTSTEP for MCCA.
In the past, many NeXTSTEP related job announcements were sent to
comp.sys.next.announce, comp.sys.next.programmer, or one of several
NeXTSTEP mailing lists. However many of the new companies are
sending their postings to misc.jobs, or advertising in mainstream
print publications.
To help spread the word about such positions, I have created a scan
profile that scans all jobs groups, and other sources, to create
a daily digest of NeXTSTEP related positions. This includes jobs
that involve NeXTSTEP, OpenStep, Objective-C, NeXT Computer Inc.,
or Display Postscript. This scan profile currently averages about
75 hits per month. Each days hits are bundled into a digest and
sent via email to the entire list. On days without any hits, no
digest is sent.

Message-ID: <475tr4$73b@spool.cs.wisc.edu>
I'm working on an app which has two subdirectories, one for IB-type
files, and the other for some associated LISP files.
I want the app to be able to function wherever the user decides to
drop it. How will it know the path to its LISP directory? I don't
want to use a hard-coded path, because then the user can't decide
where to install the app. Instead, I want the app to know from
which directory it was launched, and use that to produce a relative
path to its LISP subdirectory.
I tried using the getwd function, but it only gave me my home
directory, even though all the files including the executable
were in a subdirectory.
I'm hoping someone can tell me what function to use so the app can
get the directory it's contained in. Thanks in advance!

David,
Take a look at NXBundle - you can use [[NXBundle mainBundle] directory] to get
the location of the app wrapper, if that's what you're looing for.

Install Opener.App available at

This is a great app which will open/decode vertually any file

sending bytes/streams
receiving bytes/streams through delegate-methods
FUFTP
sending/receiving files
receiving directory-lists
FUTelnet
creating connections to arbitrary services (TELNET, POP, SMTP, ...)
sending strings
receiving strings through delegate-methods
and am currently incorporating them into our class library, thereby giving them
an OpenStep compatible interface ('const char*' -> NSString, streams -> NSData,

Under 3.3, you can use this:
#import <foundation/NSBundle.h>
NSString *appPath = [[NSBundle mainBundle] bundlePath];
Under < 3.3, you can use this:
#import <objc/NXBundleh.h>
const char *appPath = [[NXBundle mainBundle] directory];

It's a good issue to bring up, and your suggestion is already somewhat in
place, For example, the OTI StringKit had "OTI" as it's abbreviation,
CrashCatcher uses "CC_", and so forth.
What would be better than a semi-formal convention among developers for who
gets which two or three letter combination would be a solution to the
problem-- multiple namespaces instead of a single, finite namespace.
If, for example, you had a hierarchy of namespaces, this problem would
pretty much disappear.
Let's say you have a top-level namespace equivalent to the current single
namespace (which contains a reference to the first of any multiply-defined
symbols), and then every linker unit (such as a library, say) would have a
namespace of its' own below the "root" namespace, with possible children
below that (say the individual .o files in the library).
With a way to specify a particular namespace, such as
"/lib/libsys_s.a:bcopy" perhaps, you could refer to other versions of the
"same" symbol in a different namespace.
Opinions? Flames? :-)
-Chuck
PS: I wonder whether the dynamic loader stuff will have any solutions for
the finite namespace problem?

Wierd, I have g77, smalltalk, and gpc. But no gcl2.2-lisp...
I used the 2.6.3 version of the gcc compiler.

My client is currently establishing a new development group in the Chicago
area.
The company already has a successful documented history of NeXT
development, with major development groups around the country.
Due to the companies growth in the Central and North Eastern USA, my
client is putting together a top group of NeXT developers for exciting new
development projects that will be developed in their new Chicago office.
My client is looking for experienced NeXT developers with an excellent
track record in NeXTSTEP. The group will initially develop in NeXTSTEP and
Sybase, but in the near future also utilize OpenStep and WindowsNT.
Candidates must possess strong hands-on NeXT development skills with
experience in Objective-C, any RDBMS (Sybase prefered), and some exposure
to EOF or PDO.
In order to come up to speed on existing object libraries and code,
candidates will commute (fully expensed), to other development groups in
the Western USA for a short period.
My client is offering an excellent salary package, benefits, bonus, visa
sponsorship and relocation.
This is a financial related group, but is not a National or International
Bank in Chicago.

for experienced NeXTSTEP developers.
You will develop a new generation of O-O systems using state-of-the-art
technology from NeXT (OpenStep/PDO/EOF/WebObjects).
You must have a strong hands-on background in NeXTSTEP, any RDBMS and
Objective-C.
Successful candidates will receive an excellent salary, bonus, relocation
and visa sponsorship.
I need Developers, Senior Developers and O-O Architects.

Recently I installed NeXT's latest serial port server and related driver.
When I open a connection to this device using TeleComm modem software, the
modem init strings and dial strings are sent to the open connection and
echo'd back, but nothing happens. If I copy and paste the command again,
same thing. But, if I type the exact command manually, it works! It also
works fine for NEXTSTEP 3.3 on NeXT computers, and worked fine under 3.2
and maybe 3.3 with a different serial solution...
I've tried lowering the communication speed between the modem and the
system from 19200 to 9600 but this doesn't help.
Any ideas on this? Anyone else have similar trouble with your
communications app?

You will have to be more specific, here. Typically ptroff (or
troff, nroff, etc) is used in conjunction with a macro library.
Naked troff is a black art whose practitioners are rumored to engage
in ritual sacrafice either during the full moon (or at boot time).
8^)
But seriously, what macro package are you using? (or if you do not
know, what program is producing your troff input stream.) Each
macro package has different names and calling conventions for
headers, footers, page breaks, etc. It would be easiest to implement
page numbering using the macro package rather than in raw troff.
In fact, in some trivial cases it is easier to use ptroff on a pipe
and modify the raw postscript stream, than it is to mess with the
troff directly.
Also specify whether you are on moto or intel, as there are a couple
of bugs on the intel side which you will need to work around to
get ptroff to do the right thing.

Unfortunately, the global name space issues are not just limited to class
names, but involve all symbols (typedefs, enum literals, functions, etc).
To do it right, you need to be able to disambiguate when necessary when
names collide, and the name searching rules need to be integrated with the
language rules concerning scope, module definitions etc.
I think it would be extremely difficult to introduce hierarchical name
spaces to Objective-C due to the flat global name space C roots. The change
would be just too drastic.
Though the need is still there :-(

Which is exactly what Ada95 provides (with several other useful features)
This is getting off topic, but if you're really interested how a
hierarchical name space affects a language, take a glance at the Ada95

Hi all,
we are embarking on an examination of Next prograaming
and can see a requirement, in the future, for a
system/application testing tool. Basically we want to be able to
submit a series of test data cases to an environment and examine
the results in a reasonable manner. The test cases should be
able to be captured readily and cloned, to enable us to capture
one case and make modifications without re-capturing the whole
thing.
Secondly we need a way of examining the interaction of
objects with one another, this should record what message was
sent when and from whom to whom. Hopefully we will avoid having
to place multiple breakpoint in our object,
please could someone give us some pointers. I am also
interest in feedback from developers who have used tools that
have proved to be invalueable in the past. Thanks in advance.

It seems to me that the real solution is to extend to Objective-C runtime
to provide a unique identifier for each object as its loaded/instatiated
similar to how Unix provides a pid.If I reacall correctly this is alraedy
the case for instances just needs to be done for class objects. If its
done once at load time then the performance hit would be small.
Realistically the minimum denominater in a Object oriented system is the
Object thus it must be garunteed to be uniqe, a program is somewhat of a
archic though useful if restrictive concept. Since there not a one word
synonym for object devloper and interfacer programmer will have to do : )

You'll still have the problem of avoiding conflicts between the names of
libraries. And how would you fit this into the current development environment?

When linking, on my NS 3.3 Intel box, I recently noticed /bin/ld complains
when a symbol (such as _dup2) is defined in one of your .o's and in
/lib/libsys_s.a. I get an error like:
ld: multiple definitions of symbol _dup2
./Python/libPython.a(dup2.o) definition of _dup2 in section
(__TEXT,__text)
/lib/libsys_s.a(dup2.o) definition of absolute _dup2 (value 0x500231f)
Is there any way to configure the linker to use the first symbol it
encounters from the files ordered on the command line? Thanks in advance.

Hi!
I'm currently working on a programming project which would require a
_working_ GDBM or flat-file adaptor for DBKit (yes, I'm stuck with
that for the moment, don't tell me to use EOF, please). I've tried a
bit of software called the GDBMAdaptor, but it doesn't seem to work on
my system.
If you know a working adaptor like this (a working msql adaptor would
do as well), please let me know. Please also let me know whether this
adaptor supports links (one-to-one, one-to-many, many-to-many).
Thank you very much in advance.
So long,
Joe

You might also want to be aware that rexecd is a gaping security hole. I
would suggest never enabling it if possible, or to use something like the
tcp_wrapper software which will detect IP spoofing attacks....

Yes, multiple namespaces should be a feature of any large scale software
modern development environment. Turbo Pacal/Delphi solves this problem with
"units" which were also used for constructing libraries.
Of course, there are a lot of technical details to be worked out. I'll
leave that to more capable hands! :)

Newsgroups: comp.sys.next.programmer
Distribution: world
Dear experts,
I want mouse-entered and mouse-exited events for a View for purposes not
related to cursor management.
-[Window setTrackingRect:inside:owner:tag:left:right:] is, well, not quite
fabulous, compared to cursor support (how can I ensure a unique tag if I don't
know where my View will be used, see KBNS.00.0.044?).
I tried riding piggyback on the cursor mechanism, which kinda worked, using
polling to determine whether my cursor is still the current one (not in KBNS,
also because it's not generally applicable). But this does not always work:
sometimes I move the mouse pointer over a different View and the arrangement
still believes the mouse pointer is over the old View. And it only works in the
key window.
Does anyone know whether mouse pointer tracking is rock solid (then I can
eliminate NEXTSTEP (which I now suspect more than my own code) as a possible
cause for this bug)?
Has anyone made an in-depth analysis of tracking issues, with perhaps a general
workaround for -[Window setTrackingRect:inside:owner:tag:left:right:]'s
limitations? Well, most programmers will only use this for cursor management...

Well, typedefs and enumerations are conveniences for programmers that don't
really exist at the linker and machine code level.
I agree that you'd need to be able to handle all of the (global) symbol
types which occur-- check /usr/include/mach-o/stab.h for details.

Yes. I didn't claim it was easy, mind you, but it would be pretty darn

Good pointer. In fact, I was thinking of both ADA and SML when I suggested

advance.
The linker does use the first symbol that it encounters from the files on
the command line. However, the second module (from the library) will
still be added to the link if it contains ANY symbol that is needed to
satisfy some other undefined reference. This means that if you are going
to replace one of the symbols from a library module (such as dup2), you
have to replace ALL of the symbols from that module.

Hi, I need some help with something a bit odd, in that I've never
seen it discussed in the 6 or so years I've been working with NS.
It's entirely possible I may have missed it, but it's not like
it's a documented thing either...
What I'm trying to do is to replace some of the routines in
/lib/libsys_s.a with ones that are a bit more up to date etc.
This is under 3.3.
So far I have sucessfully ripped out the arch specific files
& gottten them dumped into a lib via lipo. From there I've
broken out all the individual object files & replaced what
I've needed to, and used libtool to reassemble the thing.
When I do get this far though, & try to use the subsequent
lib that I've built, it works fine - up until I hit the
routine that I've replaced. At that point it gives me an
error and a reference to the shared libraries in /usr/shlib.
It seems to me that I'm missing something relativly straightforward
about this, but damned if I know what it is, & there's not exactly a
wealth of documentation around about shared libraries & NS.
The only thing I can come up with is that I am not doing something
when creating the origional object that I want to include as far
as creating a proper link edit section. Honestly I am not real
sure.
Anyway, if anyone can help me out with this via some sort of
description etc. or tell me what I'm missing, I'd very much
appreciate it. I realize this whole thing isn't exactly commonly
done, & is somewhat non-trivial, but on the other hand it
hasn't been too beastly up until I hit this snag. And now I
am well and truely stumped.
Thanks,
Tim Scanlon

Newsgroups: comp.sys.next.programmer
Distribution: world
Hello everybody,
Sorry, but I'm an eof beginner.
I've a small question about textDidEnd:endChar:
I want to check the validity of a field with the contents of a table.
So, I tried to do something like this :
- textDidEnd: sender endChar: (unsigned short) whyEnd {
EOQualifier *aQualifier;
EOEntity *anEntity;
EODatabaseDataSource *databaseSource;
int nbr;
NSLog(@"in destin\n");
databaseSource = [destinControler dataSource];
anEntity = [databaseSource entity];
aQualifier = [[[EOQualifier alloc]
initWithEntity: anEntity
qualifierFormat:@"DST_CODE like '%s\\%'",
[(TextField *)destin stringValue]] autorelease];
[databaseSource setQualifier:aQualifier];
[destinControler fetch];
nbr=[[destinControler allObjects] count];
NSLog(@"nbr=%d\n",nbr);
return self;
}
The problem is that there is an infinite loop due to the use of the fetch
method (which invokes endEditing).
Is there some solution to avoid this problem ?
There is one if I make a link from my TextField to a special method in my
interface. But this solution does not allow me to use TABULATION.
Thanks for your answer.

Oh well, if a small company insists to be registered with two letters, or even
registers individual projects with their own prefixes, who's going to check all
that. It's only a guideline for good style (you know, being considerate and all

Just register. Or wait an eternity until isolated namespaces become available.
Or ignore the problem; nearly everyone does so, anyway.

Anyone knows what could explain the following,
I found I couldn't read those binary data files produced on other unix
platforms by my intel Next workstation. To test this, I wrote one code to
produce the data, the other reading the data.
#include <stdlib.h>
#include <stdio.h>
int main()
{
FILE *fp;
int i;
float x;
double z;
i=10;
x=1.234567;
z=1.23456789101112131415161718;
fp=fopen("bytetest.dat", "w");
fwrite(&i, sizeof(int), 1, fp);
fwrite(&x, sizeof(float), 1, fp);
fwrite(&z, sizeof(double), 1, fp);
fclose(fp);
return 0;
}
#include <stdlib.h>
#include <stdio.h>
int main()
{
FILE *fp;
int i;
float x;
double z;
fp=fopen("bytetest.dat", "r");
fread(&i, sizeof(int), 1, fp);
fread(&x, sizeof(float), 1, fp);
fread(&z, sizeof(double), 1, fp);
printf("i=%d\n", i);
printf("x=%f\n", x);
printf("z=%g\n", z);
fclose(fp);
return 0;
}
if you excecute them both on the same machine or any other unix platform,
they work properly.
output===>i=10
x=1.234567
z=1.23457
However, if you separate compilation of them and read the data by your
intel Next workstation, the results are screwed up.

What exactly do you mean by 'replacing all symbols from that module'?
From 'man ld':
-m Don't treat multiply defined symbols as a hard error;
instead, simply print a warning. The first such symbol
is used for linking; its value is used for the symbol
in the symbol table. The other symbols by the same
name may be used in the resulting output file through
local references. This can still produce a resulting
output file that is in error. This flag's use is
strongly discouraged!

DBModeller , not EOModeller, is used with DBKit. You should absolutely
not be starting a new DBKit project unless you have a very good reason to.
DBKit was "broken", in many different ways, on the day it was born. NeXT
never bothered to "fix" it, instead focusing their energies on a new,
rebuild from scratch, product-- EOF. DBKit is no longer supported and
you are in for major headaches if you insist on using it. EOF is a
vastly more productive animal.

May I hazard, that the diffrence is due to the architecture of the
machines.
One is big endian (Motorola) and the other is little endian (Intel).
Forgive me
if they are reversed. But that is exactly what happens to the bytes
representing
the numbers. Take a look at the bit patterns of the numbers, and compare
the two.

Announcements of general interest to the NeXT community (new products,

Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.
USING NEXTANSWERS BY FAX
To use NeXTanswers by fax, call (415) 780-3990 from a touch-tone phone and
follow the instructions. You'll be asked for your fax number, a number to

Subject: Adjusting height of DBTableView row elements?
Date: 6 Nov 1995 07:26:40 GMT
Organization: WolfWare
Message-ID: <47kdbg$qcu@shellx.best.com>
I'm using a custom subclass of DBTableView displaying data with a custom subclass
DBTextFormatter and have been trying to find a way to adjust the height of the row
elements in the table-view so that a larger font can be used. I believe there was
some discussion of this issue several months ago on this forum and that a solution
was eventually proposed but I have been unable to either find my archive of that
discussion or rediscover the "trick" on my own.
(Yes, I know that I should be using EOF and that there is a method to adjust the row
height in EOF but for legacy and distribution reasons for the moment I need to stick
with EOF.)
Thanks!

I quite agree.
The only thing you should need to do is make sure that you have oraserv

Needs language-level support, I'd think, particularly since a
single object might be referencing objects from two (conflicting)
libraries. The language called Eiffel has support for this, but
I don't know what one would need to do to Objective-C to get it
to work. It might not be too bad, with a little clever thought
put into it.
Not that I know what that thought would be, but I'd welcome it
if someone else has it... :-)

DBTableView. OK setRowHeight: doesn't exist in that do you have to do
something like.
[[table rowAt:0] sizeTo: and setMinSize and setMaxSize too I think.
Here's what I had to do way back when. You _should_ not need to go
this far though. I believe rowAt:0 should work ie. it should return
what uniVector is here.
object_getInstanceVariable(tableView,"rowLayout",(void **)&rowLayout);
object_getInstanceVariable(rowLayout,"uniVector",(void **)&uniVector);
[(DBTableVector *)uniVector setMinSize:fontHeight+adjust];
[(DBTableVector *)uniVector sizeTo:fontHeight+adjust];

Message-ID: <47lbt9$4ff@cisun2000.unil.ch>
I'm wondering if anyone knows if there will be any revisions to the OpenStep
spec from its current state.
Also, does NeXT really expect that someone would be able to implement an
NSCStringText object from their description? Including properly using their
freakish (sorry) internal structures? It seems like parts of the OpenStep
spec were really designed for those with source code from NeXT.
How about an object for file access?
Also there are things cited by the specification which are missing, i.e.
various file formats, archiving streams, and constants.
If the current specification is _the_ final which anybody would have to
implement I can't see that OpenStep will be terribly compatible across
implementations. That is, unless everyone writing an implementation agrees
to fill in the holes together.
Thanks for any info.

Message-ID: <47lo70$5gi@Venus.mcs.com>
Let me appologize in advance for this. I am trying to make use of
NXConnections for the first time and nobody else that I work with has
ever used them either. So I keep asking dumb questions in my quest
to get this thing to work.
That said, HELP again. I can't seem to get the server program to
return data. To this point, the server has done all the work, based
on information sent from the client. Now I need to get it back. The
server program creates a file (code for this has not been included)
I wanted to have the server create a temp file name and send that name
back to the client so that the client could then request the file
that it wanted by name. I could not get the string with the file name
to pass back. I gave up and let the client tell the server the name of
the file, and moved on. This is not good, and I expect that the answer
to the current question will lead to fixing this correctly.
The current problem is that I am trying to transfer the file back to
the client over a connection. The 2 programs run on different hosts,
that don't trust each other and the server runs as root so can't write
to the client machines file system. Also, the file should be owned by
the user running the client. I tried to write a little function to
transfer the data back to the client in small chunks. I get the the
correct number of bytes of data, but it is all blank. (I know the file
is correct on the server side)
What am I doing wrong in sending back the data?
Thanks for help

Yes, the OPENSTEP specification will undoubtedly be revised as time goes
by: OPENSTEP 1.0, 2.0, etc...I'd also expect that the current spec will be
re-released, minus the typos and errors, after a few more details are
worked out (see below).

Actually, NeXT doesn't expect anyone to duplicate any of the classes in
OPENSTEP from the specification alone. That's why we will provide a
reference platform (NEXTSTEP 4.0), and a compliance test suite.
I hope that eventually the published spec will be sufficient to implement
OPENSTEP, but we're many man-months worth of effort away from that, and at
this point, implementing the specification is a much higher priority than
documenting it.
> It seems like parts of the OpenStep spec were really designed for those

That's *exactly* who it was written for (i.e. Sun). The current
specification document is more of a guide to the OPENSTEP API than a
comprehensive Specification. I believe that the idea was to have the spec
available, in some form, before the implementations were.
> How about an object for file access?
I believe NeXT's version of OPENSTEP will contain an extension
(NSFileManager?) for dealing with files. Unfortunately, this probably
won't be available in Sun's OPENSTEP (at least in the first version).
> Also there are things cited by the specification which are missing, i.e.

This is a known issue. NeXT is working with Sun to ensure a high degree
of interoperability in these areas. I expect they'll eventually get added
into the spec.

Any implementation of OPENSTEP has to pass the compliance tests before it
can use the OPENSTEP trademark. This should weed out most of the gross
incompatibilities.

That's the current plan. You can, of course, count on a high degree of
compatibility between NeXT's OPENSTEP products (OPENSTEP/Mach and
OPENSTEP/NT).

Careful!! This assumes that a float is 4 bytes in size which isn't
necessarily true on all systems. And according to the on-line Portability
Guide:
"Some processors modify the value of a floating-point number if that value is
invalid, so the swap functions for floating-point values can't simply return
float or double."
NeXT has provided all sorts of byte-swapping functions which are
discussed in the Portability Guide.

Summary: recieve send time out

Hi,
I'm using a PDO server running on a sun (SunOS Release 4.1.4) and
am currently having many problems. It seems that after a certain
amount of time clients can't connect. The not connecting is on a per
machine basis. One person may be able to connect, and another may
not. What happens is that I send NXConnection a
connectionToName:onHost: message and it returns a valid connection
(isValid even returns TRUE), at any point after that if I try to
message the returned proxy with anything, it raises with errno 11012,
send timed out...Again, this only happens to some machines after
they've been running for a while, it doesn't happen to all machines
and is never consistent as to when it will happen. If I reset the
machine the problem is happening on, it'll go away. To me, it seems
that the problem may lie with nmserver, and that for some reason both
sides are maintaining bogus connection information. Any suggestions,
help, would be great.

Extensions !?
Good idea to move forward, but does this mean, for the OPENSTEP developer
using the "reference platform (NEXTSTEP 4.0)", a choice between using nice,
powerful extensions, or being OPENSTEP compatible? And what about the first
version of OPENSTEP for NT?
Will these extensions be available as a separate product? There are
already nice parts of NS (the 3DKit for instance) not part of OPENSTEP. The
more there is, the more difficult it will be to write OPENSTEP compatible
apps. Please make extensions from NeXT, Sun and others available to
OPENSTEP. Isn't it what ObjectWare is all about?

Hi!
The problem is: even if you get hold of a gcc for NSfIP, you still don't have
the include files, which are (at least a good lot of them) commercial.

Yes, but:
If I own NS Dev 3.2 and want to use the new gcc from 3.3 , where can I
get it? And by the way, I never was able to use ObjectiveC on another
platform than NeXT! Wasn't there a deal that NeXT was allowed to use
gcc and GNU got the ObjectiveC stuff (ok, you can compile it, but you
don't have the runtime library available, do you? Please point me to a
source!
Thanks in advance,

Is anyone out there using a recent version of Prolog on NEXTSTEP? I've had
a search around the archives and there was some info from way back in 1989
on CProlog1.5, SBProlog and Quintus. I get the impression that these are
probably extremely out of date now. We're needing to run Prolog for a
course starting next year.
Any hints, patches, binaries, source, info or anything welcome.

I'm dealing with somewhat the same problem. I do know that the byte
order is reversed on different platforms. I have a dataset produced on
a PC in binary format that contains integer and real*4 data. I have
been able to decode the integer part by using
int swapLH(i)
unsigned i;
{
unsigned bytes[4], ret_val;
bytes[0] = (i & 0xff);
bytes[1] = (i & 0xff00) << 8;
bytes[2] = (i & 0xff0000) >> 8;
bytes[3] = (i & 0xff000000) >> 24;
ret_val = bytes[3] ^ bytes[2] ^ bytes[1] ^ bytes[0];
}
I then call
i = swapLH(j);
to convert the readin j to an integer on my NeXT.
I'm still having problems on the floating point however.

Ok ObjC Guru,
Does anyone know hoe this might be done??
I have a window with some buttons in it. When the user clicks on a certain
buton, I want to drop the window down to un-cover a row of hidden buttons that
are previously not visible because they are below the bottom border of the
window. I do the following::
NX_HEIGHT ( &newWindowFrame ) += offset; // Number of pixels needed
[myWindow placeWindowAndDisplay: &newWindowFrame ];
This code causes the window to grow from the top, and if I set all of the
buttons to stretch from the bottom, then they are all pulled up ok but this
does not work for two reasons.
1. When I try to return the window to its original size, the internal
buttons do not return to there original locations, so i get a mess.
2. I dont want the window to grow from the top and have all of it's
internal buttons move up. I want it to "Drop Down" and then when the user is
done, to close back up to the original size.
Any ideas??

Actually, though, I think even a bigger problem than class name clashes is
the issue of category method name clashes. For example, person X adds
a category to Object that has a method called Foo, but in another category
of Object, in some other kit I'd like to use, Foo is ALSO used for a
completely different method function. It's a nightmare.

The "-m" option to ld will do the trick.
However, you'd be better off removing the local redefinition or adding
something like a "#define dup2 my_dup2" some place global to your source
code.

-invalidate:: just recursively distributes itself over its subviews, clipping
the rectangles in its NXRect array argument, and skipping subviews that
obviously don't intersect with those rectangles.
Some comments:
1. The documentation says ``Invalidates the View and its subviews for later
display.'', but this is not true: it does absolutamente nothing at all, other
than distributing itself over its subviews.
2. The documentation does not prohibit you from sending this message yourself,
but then you ought to know that it probably can only handle either 1 or 3
rectangles, not more (which the documentation doesn't specify).
3. The documentation does not specify that you should invoke [super
invalidate::] (to distribute those rectangles over the subviews), and that you
should only record what areas of the drawSelf:: stuff are affected (otherwise
there will be O(n^2) -drawSelf:: messages instead of just O(n)).
4. A related issue is that the documentation of -[Clipview setDisplayOnScroll:]
(-[ScrollView's setDisplayOnScroll:] merely invokes its equivalent in the
content view, which is a ClipView) says ``If flag is NO, the ClipView is marked
as invalid but isn't displayed.''. But I've tested what happens if the
ScrollView is sent a -displayIfNeeded message (which recursively descends the
View hierarchy), and this does not do anything.
Criticism:
Even if all these things were documented, there is still the question of what a
poor programmer is supposed to do (let's assume a sensible programmer, who does
not follow the hack-away-until-no-bugs-appear style). Does this situation make
sense to anyone (I thought I should ask before letting the axe fall),
preferably with a programming example?

Organization: Communications Vir, Internet Access Montreal.
Message-ID: <47oka0$43k@Vir.com>
Hi,
I'm having trouble initializing a NXStringTable programatically.
Basically this is what I do. I open a memory stream, put the data
(formated for a string table) into it, with NXPutc(), then reposition the
pointer with NXSeek(), and finally send the message readFromStream: to the
NXStringTable object. (NS3.2 DEV, NS3.3 USER, INTEL )
Here's some sample code strBfr is memory buffer allocated with
malloc() and strBfrSize is the size in bytes.
-------------------------------------------------------------------
NXStream *aStream;
NXStringTable *aStringTable;
int byteCount;
aStringTable = [[NXStringTable alloc] init];
aStream = NXOpenMemory( NULL, 0, NX_READWRITE);
/*----------------------------------------------------------------------
Copy data into the stream.
----------------------------------------------------------------------*/
for( byteCount=0 ; byteCount < strBfrSize; byteCount++ )
NXPutc( aStream, strBfr[byteCount] );
NXSeek( aStream, 0, NX_FROMSTART );
[aSrtingTable readFromStream: aStream];
NXCloseMemory( aStream, NX_FREEBUFFER );
----------------------------------------------------------------------
What am I doing wrong? How else could I initialize the NXStringObject
without reading a file? Any pointers to example code will be appreciated.
Thank you in advance,

If anyone has experience with EOF for PDO, or better yet, would be

It might be better to try looking at the delegate methods for validation in
EOController (I assume you are associating your field with a controller.)
A useful method (from memory, so don't count on the exact name)
controller: willSaveEdits: toObject:
I use this method to do most of my minor-entity validation.

What's wrong with using the read:/write: methods? For example:
NXTypedStream *stream;
NXStringTable *aStringTable;
aStringTable = [[NXStringTable alloc] init];
stream = NXOpenTypedStreamForFile("stringTableArchive", NX_READONLY);
if (stream) {
[aStringTable read:stream];
NXCloseTypedStream(stream);
}

All:
Has anyone heard of a problem with the NSIntel3.3 compiler generating the wrong
code where registers are concerned? I have been trying to solve a problem with a library
where one of the methods within a class is being compiled wrong. One of the local
variables in a method is being assigned to the same register as the argument to the method.
The two variables are not even remotely used together in the code itself, but no matter what
I try to do, the argument (being of type id) gets corrupted by the operation of the method.
This is not the code itself, but it illustrates what is going on:
- foo:anObject
{
id bar ;
int x ;
int y ;
bar = [[List alloc] init] ;
x = [anObject doSomethingWith:y] ;
}
Although the method is more complicated than this, I can assure you that the
interaction between the anObject argument and the bar variable is nowhere to be found
and yet the compiler is merging the two of them. Now when bar gets assigned to the new
instance of the List class, anObject is corrupted because they reside in the same
register.
Has anyone seen this or does anyone know about a problem like this?
Thanks in advance for any light shed on this one...
Cheers,
Chris

Hi Bernhard!
I you've got the NS3.2 Developer, you can compile anything for Intel and 68k.
Just grab the sources of gcc somewhere (you might use an even newer version
than
NeXT itself does. I once had compiled a gcc 2.6.3 and it worked just fine.)
BEWARE: Compiling gcc on a slow machine (486 or 040/25) takes quite some time.

Message-ID: <47qkvo$qa9@cisun2000.unil.ch>
I am trying to make a subclass of NSData which would contain its own NSData
object as described in the Class Cluster section of Introduction to
Foundation. However I run into a strange problem with the archiving.
Everything else seems to work fine.
Essentially it seems I can't stop NSData from writing the bytes in it's own
format (archived chars). Since in my subclass of NSData all the data is of a
specific type I would like to write it out using a machine independent and
compact data format.
I get both an archived NSData and my own array encoding in the resulting
archive.
Since I need to encode super I do the following:
- (void)encodeWithCoder:(NSCoder *)coder
{
unsigned int count = [self count];
unsigned int length = [self length];
[super encodeWithCoder:coder];
[coder encodeObject:c_type];
[coder encodeValueOfObjCType:@encode(unsigned int) at:&count];
[coder encodeValueOfObjCType:@encode(unsigned int) at:&length];
[coder encodeArrayOfObjCType:[c_type cString] count:[self count]
at:[valueData bytes]];
}
- (id)initWithCoder:(NSCoder *)coder
{
void *bytes;
unsigned int count;
unsigned int length;
self = [super initWithCoder:coder];
c_type = [[coder decodeObject] retain];
size = math_aligned_size([c_type cString]);
[coder decodeValueOfObjCType:@encode(unsigned int) at:&count];
[coder decodeValueOfObjCType:@encode(unsigned int) at:&length];
bytes = malloc(length);
[coder decodeArrayOfObjCType:[c_type cString] count:count at:bytes];
valueData = [[NSData dataWithBytes:bytes length:length] retain];
free(bytes);
return self;
}
Thanks for any info. BTW This is for an OpenStep replacement of Storage
which I will give away.

Andy,
I have successfully modified several of our applications to create, edit
and print WriteUp documents using the API.
Did you set your default database to use the API? You must set the
following default for each user using the Terminal application.
dwrite WriteUp API_Enabled 1
To simplify my life I added the following code to the main controller of
all of my applications which does the aforementioned dwrite everytime a
user runs an application which uses the API. This was so that I never
forget to do it when creating a new user (will not matter now).
// Use a UNIX system call to enable the WriteUp Application Programming
// Interface for the CaseLetter and SlantLetter subprojects. If the user
// does not have the following default set, then selecting the Save button
// in either a Case Letter or Slant Letter window will result in a
// "spinning multi-color cursor from hell", requiring that the CaseView
// application be killed!
system("dwrite WriteUp API_Enabled 1");
I hope this helps.
Please note that you should have a valid license to use most of the
features that the API provides! [sure, you can create a new document, but
if you can not save or print it, then why bother] If you do not have one,
but are evaluating whether to purchase a license, then you might contact
greg@afs.com and ask him if you could have a short-term evaluation license
string (I did this then bought the product since it works so well). If
you need further help, then jack@afs.com might be able to help you - he
sure has been helpful to me!

Hey everyone, I was wondering if someone can help me. I'm currently working on a small NeXTStep application to get familiar with NeXTStep programming, I know ObjectiveC, and am using NeXTStep Developer 3.3. I was wondering, after using INterface builder to build the interface, how can I implement all the "functions" I have put into the interface? I.E. For the function "List Names" for example <a button in the interface>, how do I go about connecting "List Names" with the object function "List Names"? Does
anyone
have any sample code or know anyplace I can get it that shows how to link all the functions in the interface with actual functions in the code so that the functions in the itnerface work properly? I hope this message is understandable, if you still have problems understanding, please ask. Please try to send email to me with an answer if possible, seeing I dont frequenet the newsgroups too much. Thank you very much

The XSB prolog system is available for free from SUNY-Stony Brook in

This is a reasonably full and recent extension of Edinburgh syntax

indeed, among other systems). Whether it will suit the needs of your

Message-ID: <47qvkc$q2e@csugrad.cs.vt.edu>
I want to develop an application that is able to display (and
preferably input) Japanese text, and I am trying to look into the
feasibility of this. I don't have the Japanized version of NEXTSTEP.
The two main problems I see for NEXTSTEP are lack of Unicode and lack
of fonts. The first problem will be solved with OpenStep. I'm not
sure how you would work around that in regular NEXTSTEP, or if it's
even possible.
Even if I do wait until NS 4.0, there is still the font problem.
I don't think that there are any free PostScript fonts for Japanese.
I have seen some bitmap fonts out there. Is it possible to convert
bitmaps fonts into NS PostScript fonts? I would normally expect it to
look pretty cheesy, but I seem to recall reading that DPS uses ordinary
bitmap fonts for normal point sizes anyway. Printing would be another
matter.. but I have some software under Windows that uses 48x48 bitmap
fonts, and they look suprisingly good on my laser printer. So maybe the
font problem is solvable.
So, any suggestions? (No, I don't want to involve X, either.) It seems
that it would be pretty tough to display Japanese with a normal text
object, because there are far more kanji than there are ASCII codes.
Would it be necessary to resort to drawing bitmaps to a window? I
assume this problem would go away with NS 4.0, and it would only be
necessary to find a font.
(P.S. Any pointers to Japanese-related software that runs under regular
NEXTSTEP would also be welcome. I ran across an edict interface called
NXJisho, but it was binary-only for M68K, and the author's e-mail
address doesn't work..)

I have NS 3.0 running on black hardware. All I really want is to be able to
compile *something*! I have been working at this for the past 3 months. I ftp a
prebuilt compiler, install it, and it yields a "Floating exception" if I simply
execute it without supplying a file for compilation. If I do give it a file it
usually just cats the #include files to the screen with the source code, and
dies. I have tried three different builds of gcc from various places on the
net. I don't have a Next Dev CD, or else I'd use that. If someone either knows
where a 3.0 compatible compiler can be found, or if someone has a copy of gcc
that is covered by the FSF License then maybe you could send it to me. I have
all the includes, the assembler (as), the archiver (ar), and as far as I know
they work.
Do I have to have the linker to compile properly? If so, where is one, I know
it's "ld" but I need a binary that runs under 3.0? I hate these chicken/egg
compiler problems. I have the source for almost the full gnu system, but no
compiler to build any of it with.
What I ultimately need is to build a FORTRAN compiler, but I had hoped that by
getting a functioning C compiler I could build FSF's "g77" (that's a F77
compiler, right?).
Thanks for any help.
PS I'm a college student (read non-profit), so any help in the way of NSDev 3.0
CDs will be greatly valued and appreciated, and not used for any monetary gain.

I've come across the following situation whilst fixing a bug in Resound
(a sound app). It's a common situation in many apps, so even if you're
not familiar with the SoundKit, perhaps you can still help me. A user in
Resound can often close Sound windows and open new ones at will, so the
following situation crops up:
1) I'll cut a sound from a NeXT SoundView. Either the SoundView or its
associated Sound puts the information on the pasteboard and declares
itself as the owner of the pasteboard.
2) I'll free the SoundView and its Sound.
3) I'll create a new sound and SoundView with some data.
4) I'll cut something from that SoundView.
What happens now seems to be: the Pasteboard attempts to tell the old
owner that a new owner is changing the data on the Pasteboard
(pasteboardChangedOwner:) but the old Sound/SoundView pair has been
freed. BANG! Resound keels over (message to a freed object).
Surely there must be a mechanism for cutting and pasting without having
to keep around all the objects that did the cutting and pasting
throughout the life of the application! What am I doing wrong here?

Description of Contents
Object Currents accepts articles in the following classifications:
Articles (3 - 5 pages)
All submitted articles must satisfy some genuine need in the software
community with respect to object-oriented development, be highly
informative and lucid, and be appropriate to the intended Object Currents
audience. Articles containing new and advanced technology or method, with
an "eye on the future" perspective, and making best use of hypermedia will
receive highest priority.
Article sections should be numbered. Articles must have a brief one or two
paragraph abstract/summary. Recommended are sections on
introduction/background, goals and audience, unique contribution,
problems, benefits, issues and related works, conclusion, and
acknowledgements and references, as appropriate. Diagrams and examples,
including code fragments and complete programs, should be plentiful to
exemplify concepts.
Series (3-5 pages, 2-8 installments)
A series is a collection of articles offering the author an opportunity to
address a topic in great depth. The series may run from two to eight
installments. Series should be clearly partitioned into subtopics.
Column (2-3 pages)
Columns are designed to provide an ongoing discussion of a topic area,
offering the columnist an opportunity to cover a topic in great breadth over
an extended period of time, and to track changes and trends in the topic
area as the technology matures. Over time, the readers of a column should
gain an appreciation for the approach and style of the columnist and be
able to identify the people, companies, and products involved. Editorial
comments by both the author and readers are encouraged.
Newsgroup Dialog
The editor will take a thread or threads from the comp.object newsgroup
and provide commentary. Such threads may be started by the Editor and
may be related to the current issue.
Fun and Games
Puzzles to be picked up from the C++ Report and the net. Puzzles can
include obfuscated programming code, preferably from a well-known
language, or any other sort.
Questionnaire
A questionnaire will appear in each issue raising questions of importance
to the object community, typically concerning the issues raised by that
issue. The results from the last questionnaire will appear in the next issue
of Object Currents.
SIGS Bookshelf (2-3 pages)
Reviews of books, videos, and conferences. These should have the "eye on
the future" perspective of Object Currents. A review should describe the
purpose, content, and intended audience of the item and make critical
comments on its accuracy and success in fulfilling its purpose. If
appropriate, the author should comment on the suitability of the item for
educational purposes.
Movers & Shakers
Interview or profile of object industry VIPs. An interview or profile should
discuss the "movers" background, such as research interests, current line of
work and primary contributions, primary work today, object of interview or
profile, and conclusion. An "eye on the future" perspective should be
maintained, including a discussion on where the "movers" contribution
will bring the object community in the near future.
Code Watch
Source code will be provided at the SIGS site, possibly mirrored from
another. This code may come from SIGS journals or anywhere, such as on
the net.
Editorial Comments
Comments on the previous Object Currents issue, including other editorial
comments, provides a means of feedback and interaction for both author
and reader.
Potential topic areas are enumerated below; this list is not exhaustive and
creativity is encouraged. Topics should be drawn from new and advanced
areas of object technology. SIGS topics are very similar, but Object Current
articles emphasize the latest and most advanced technology, how it should
be incorporated today, and where it is leading tomorrow.
Applications
Authors should discuss how advanced object technology should be used to
improve current practice. Successes and failures can provide valuable
feedback on future directions and what to follow and what to avoid. How
new or advanced techniques improve quality, productivity, or problem
solving should be reported. Learning curves, obstacles and their removal,
required support, metrics optimization, and other issues where
improvement is needed in the software industry today should be addressed.
Transitioning from old to new technology can be addressed.
Example Topic Areas:
- Commercial, engineering, and scientific applications.
- Systems support and impediments
- GUIs, visual programming, hypermedia
- Application frameworks and patterns
- Purchased class libraries
- New class library ideas
- Application portability
- New standards
Hypermedia
The World Wide Web has been described as object-oriented. New approaches
to hypermedia, especially the World Wide Web, are desired. New and
innovative use of the Web and/or hypermedia by object-oriented applications.
Example Topic Areas:
- The object-oriented WWW
- Better approaches to hypermedia with object technology
- Innovative use of hypermedia and the WWW by object-oriented applications
Idioms, Languages, Environments, and CASE
More powerful and expressive idioms and techniques in object-oriented
programming are desired. New languages and environments can be
discussed, including research languages. New paradigms in OO, such as
delegation, and new environments, such as metacase, are of importance
today. Compare different approaches and implementations. Issues of
expressiveness, flexibility, orthogonality, power, correctness,
portability, availability, suitability, and style are of interest.
Subjectivity is a factor in the choice and acceptance of languages and
environments, and should be kept in mind.
Example Topic Areas:
- New constructs in OO
- Best use of new language or environment - Is it for the reader?
- New CASE and why it should be used in real development
- New Idioms or advanced programming techniques to follow
- Reflective systems and extensibility
- Metasystems
- Advanced use of polymorphism
- Advanced uses of inheritance: multiple, dynamic, shared, etc.
- Designing for reuse
- Utilizing reuse
- Prototyping
- Migration and coexistence
- Efficiency/optimization vs. power expressiveness
- New Standards
Databases
New developments and advanced topics in OODBs can be addressed.
Where, when, and why a new technology is required. Reasons for
transition to and acceptance of object databases including advantages (over
older and/or other approaches) and new ideas should be presented.
Example Topic Areas:
- New OODB technology
- New and novel uses of OODBs, such as for business objects
- Distribution, concurrency, reliability, security
- Advanced Languages support
- Uses and Integration with other object systems - E.g. languages, CASE,
business objects
- New object query languages and use and 4GLs
- Schema evolution and its importance
- Superiority of new OODB approaches over others
- New standards and ideas
Analysis And Design Methodology
New techniques in analysis and design are always being devised. Older
methods are evolving and fusing into newer methods. The need to utilize
the new methodologies and how to best achieve their acceptance is of real
importance today. Identifying future trends is of interest to readers.
Comparisons between the new methodologies and what they imply, or at
least why the new technique is superior.
Example Topic Areas:
- New and better methodologies and their use
- Best or creative uses of OOA/D, perhaps in new application domains, such as
business.
- Most relevant domains of use, strengths and weaknesses
- New techniques proven to be effective
- CASE/METACASE support
- Extensibility and reuse
- Prototyping
- Use in processes
- New ways to perform reviews and walkthroughs
- Improved cost drivers, moving effort upstream
- Standards, including new fusion efforts
Process
Software engineering processes are a hot topic today. The SEI's CMM
level 1.0/2.0, ISO SPICE and the modern management practice of process
improvement are of great relevance to today's software development.
Discuss how object methodologies and technologies fit in with and better
support modern software engineering processes, such as Boehm's Spiral
Model of development.
Example Topic Areas:
- New and better development processes - how they relate to OO
- OO's basis in modern and flexible processes, especially in analysis and
design
- Experience with modern process and OO
- Handling the transition to modern from legacy processes, such as the
waterfall model
- Novel use of analysis models
- Metrics and process
- Process optimization
- Process and methodology, suitability of various methods to various processes
of development
- Process specialization and generalization - what should be tailored and what
should be standardized intra- and inter- organizationally.
- Standards - ISO/SPICE, SEI, etc.
Management - OD - Project Management - Testing
Nontechnical issues affecting OO transition and operationalization include
how developers, managers and users, respond to and are affected by the
introduction of object technology. Psychology of transition and change,
organizational improvement, individual, team, and organizational
learning, and other "people" issues can be addressed. Also how new
object-oriented technologies can affect project management: planning and
estimating, SCM, quality, and testing.
Example Topic Areas:
- Reduced cycle time, reduced time to market
- Improved metrics
- Applying ISO 9000, TQM, CMM, ISO/SPICE with object development
- Improved business measures, e.g. ROI
- Introduction of new techniques, innovative approaches
- New management techniques for object development and integration
- Better individual, team, and enterprise-wide learning, coordination, and
integration
- For developers, successfully managing upwards. Bringing improvement to
your organization.
- For managers, successfully managing the development staff.
- Obstacles of resistance to new object technology and overcoming them
- Pitfalls and errors to avoid
- Organizational support during the learning period, and minimizing the
learning curve.
- Quelling overanticipation of reuse or the "silver bullet" syndrome with OO.
- Benefits and drawbacks of empowerment to object development
- Staffing for OO development - e.g. Boehm's 5 principles
- Corporate object management
- Strategic object modeling: enterprise-wide objects
- Enterprise modeling and design
- Objects as a corporate resource
- The changing role of developers in shops in which the product is not
technology
- Project resourcing: changes in developers roles
- Benefits, drawbacks, management of prototyping
- Managing, controlling development, discovering/sharing of reusable
components
- Dealing with user needs and expectations
- Standards
- How do object-oriented systems call for a new testing paradigm?
Education and Training
How the new OO techniques are best taught and how training should be
provided is of real importance today. One Level 5 organization provides
45 days training to all developers before starting, is this best? What are
the alternatives? The need for improved education and training in both
academia and industry, especially with regards to real-world development,
is of importance. How should new OO techniques be taught or used in
initial development efforts?
Example Topic Areas:
- Application of new learning techniques to object education; such as learning
tools
- Teaching/learning object technology
- Experience reports
- Making the transition from procedural to object environments
- Transitioning from programming to object-oriented analysis, design, and
programming
- Learning curves. How long does it take to reach proficiency, or various
levels of expertise?
- How can the learning curve be optimized?
- Humphrey's PSP

Subject: Get signal on parallel port of NS/intel
Hi, Steppers.
I'm developing a program which uses parallel port of NS/intel to print
large number of characters. When paper is out, printer notifies it by
some signal line and program get notified it by ioctl() functions. To
build this program, I referred to header file placed at
/usr/include/bsd/dev/i386/pp_extern.h. But, values returned by ioctl()
function seems to differ from the descriptions in the header file.
Therefore, when paper is out, my program misses to catch the event and
prints garbage. So, I'd like to know where can I get exact information
about parallel port.
Thanks in advance.

You wanna know why!!!!
Because if I put 2000 NSValues into an array and I have a hundred of these
arrays the amount of memory starts to really add up. That adds up to 12.8M
just for the objects! The storage is inefficient and the whole thing takes
up a lot of memory. If I have some typed data that I have sticking around I
should have a means to store it efficiently (without the overhead of an
object) and to archive it in an architecture independent fashion. This is
easy to do with an NSMutableData that knows what type of data it's storing.
Thanks for any responses to the first question. Actually as long as I have
the object be a subclass of NSObject and not NSData everything works fine. I
just have to reimplement some chunks.

Message-ID: <47t95h$olh@hippo.shef.ac.uk>
Hi there,
I am new in NeXTSTEP programming. Currently, I am studying the source codes
of a kit called iconkit. In the kit, there is a class called "IKCell" which
works in conjunction with another class "IKIconPath" to provide support on
drag-and-drop, and displaying of icons to represent files or directories.
What I don't understand is, there is an instant method "drawInside" in the
IKCell class which seems do not get invoked anywhere in the kit, but if I
remove it from the source, the result is all the icons on the directories path
disappeared. I think there must have some methods which implicitly invoke
this method without my notice.
If you know which method has invoked it implicitly, please kindly
tell me. If you can tell me the theory behind, then it is even better.
Thank you very much.

More like person-years.
Also, the tighter the spec, the more constrained the implementation,
which may constrain things like performance optimization or
semantic improvement. (Or optionally, the faster the 'spec' gets
out of date.) Plus, there are several errata in the document.

NeXT's first version of OpenStep will contain at least one object
for dealing with files, NSFileManager. But that class has been
around for quite a while (internally) and it exhibits several
weaknesses, so we may be providing something (hopefully) better
additionally.

And OpenStep/Win95. Well, at least to the degree with which
WIN32 as implemented on NT and WIN32 as implemented on Win95
allow for compatibility (which depends on what any particular
individual is thinking when they say 'compatibility').

Yes, a choice. Extensions are a fairly small part of NeXT's
OpenStep, however, although some extension bits are fairly nice.
We haven't rampantly added extensions, either, in deference to
OpenStep.
Except for a few arcane bits which are simply not implementable
on the NT/Win95 (or vice versa, under MACH) operating systems
(unless someone out there has written a public domain
implementation of fork() for WIN32??), the Foundation on Windows
is functionally equivalent to the Foundation on NEXTSTEP. Ditto
with the AppKit I believe, but I'm just less familiar with the
AppKit on Windows. The implementations of a few things are
different, obviously, to better play in each world.

The extensions to OpenStep will be available in our OpenStep
implementations, not as a separate product. The 3DKit is not
an extension to OpenStep.

Hello I'm intrested in learning how to write drivers for Nextstep and Unix
in general. I't seems that a second computer is practically mandatory to
do remote debugging. My question is can a Linux or minix box be used with
GDB to debug a Next driver. I assume linux drivers can be debugged from
Nextstep? Anyway I was thinking of buying a cheap 386 and loading linux so
I could use it as a remote debugger for my intel machine. The other more
expensive option is to buy a cheap Next box like a old mono station. Can
the debugger be upgraded without upgrading the OS. For example can I get
and old mono station with say 2.1 on it and add the latest version of
Next's GDB ??
And last but not least since Nexts driver kit is significantly different
from generic unix drivers is there another source of help on it besides
what's avialable on line. Something simialar to the several good books on
using the application kit?
There's all kind's of neat hardware out there that doesn't have Nextstep
drivers I want to learn how to write them to be free of waiting for
Nextstep to support all the possible hardware configurations. For example
I have a MiroCrystal Video card it doesn't look like Next is going to
support it and Miro's dropped Nextstep support. So to heck with them I'll
do it myself.

Hi -
It sounds (heh) like you are using the lazy data provision of the pasteboard
(i.e., calling declareTypes:num:owner: and not writing the data immediately
afterwards). The Pasteboard expects that it can message "owner" any time
later. One thing you can do is keep track of whether you have promised but
not delivered data to the pasteboard and be sure to write it (if needed)
in your -free method. Another solution is to manage the Sound instances
separately from the windows - then you can keep track of sounds with pending
pastes and "retain" them until they are no longer needed (the pasteboard
changes owner).
Good luck!

This thread caused me to resurrect an idea I had awhile back.
Instead of having an NSArray filled with NSValue objects, I thought
it would be nice to have an NSValueArray. NSValueArray instances
would work like a Storage instance in that they would store things
as an internally allocated array of raw values. On the other hand,
it would work like an NSArray by wrapping values in NSValue instances
as necessary for methods like -objectAtIndex:.
I had the same problem Sean had, but managed to use a very hacky
workaround to fix it (see the -encodeWithCoder: methods). In
general, it seems that class clusters (at least NSArray and NSData)
use their API to encode things. For NSArray this means that
NSArray's -encodeWithCoder: calls -count to get the number of
objects and -objectAtIndex: for each object, which is then encoded.
In the above-described implementation, that is suicide (_think_ of
all the autoreleased NSValue objects created for no good reason!).
The source code is included below as a uuencoded .tar.gz file. If
you can't read the source code, you shouldn't be using this. [And
that is _not_ saracasm. _I'm_ certainly not going to support it.]

Hi Andy!!
I've used the WriteUp API a little bit, and I can give the following advice
concerning your problem:
1) ensure that you have done the following:
DWRITE WriteUp API_Enabled 1
2) The WriteUp API comes with a test program, Remote.app. If that program
works on your machines, just use the connection method inside it (Remote.app
comes with source).
Good luck!!
(Now, if only they'd get enthusiastic about DOCUMENTING the bloody thing!)

Is there a C-function available or a hack to do this? (The name should be

Have fun!
Driver development is a hard business. Besides remote debugging you could
resort to some kind of printf-debugging. DDM is also an alternative. It
becomes a bit annoying having to reboot the machine several times during a
session, though.

Wolfgang:
This is really just a C question and in the future I would suggest
posting such questions to a C group.
But, here is a quick answer to your question: use the argv[0] value.
Within a C program, argv[0] stores the name of the executable.
example code:
#include <stdio.h>
void main(int argc, char *argv[])
{
printf ("We are running: %s\n", argv[0]);
exit(0);
}
I suggest that you pick up the book "The C Programming Language" by
Kernighan & Ritchie. It will answer most of your questions.

L.S.
We're building an application in which we have a main view with several =
subviews acting as layers. These layers each consists of line-drawings =
and/or textfields.
Because we want to be able to speed up the redrawing of main view, we =
would like to buffer the layerviews into images and use these images =
for the redrawing.
We first tried to do a [self copyPSToStream:] inside the drawself of =
each layer view. We tried to use [image loadFromStream:] but that =
didn't work so we used the stream to initialize a NXEPSImageRep which =
we added to a NXImage with useRepresentation. Then composited the image =
to the screen. That worked brilliantly.=20
But then we want to zoom in en out without blowing up the image itself. =
The zooming has been implemented by changing the coordinatesystems =
(through setDrawOrigin:, setDrawSize: and setDrawRotation:). This =
worked as long as the rotation was 0. But with nonzero rotation we =
would get deformed images.=20
We also tried to use a NXCachedImageRep but the NXImage failed to add a =
NXCachedImageRep when called with useCachewithDepth:NX_DefaultDepth as =
stated in the General Reference Manual.
=20
After a couple of days of trial and error we have a couple of questions =
to you all:
1. Is the idea of caching views in NXImages at all wise or should we be =
doing it=20
completely different.
=20
2. Why won't an NXImage create an NXEPSImageRep (or any other for that =
matter) from=20
an loadFromStream with a stream filled with ordinary eps-data (using=20=
copyPsToStream), which when drawn directly on the screen causes no =
problems at=20
all.
3. Why doesn't useCacheWithDepth works like advertised in the manuals.
4. Why don't we get rotated eps-code into an image (we know we can't =
rotate the=20
image itself).
We use NSFIP Developer 3.2, User 3.3.
If anybody has some example code, we would be very gratefull.

P.S. Responses will be summarized to the news-group.

Hi -
I think you are looking for argv[0]. e.g.,
void main(int argc, char **argv)
{
printf("I am program: %s\n", argv[0]);
}

No, you would need another machine running NS with specific networking drivers.
But don't let this dishearten you. Writing display drivers is relatively
straighforward as long as you have decent hardware documentation. There is some
on-line documentation and also example source code (see QVision example).

This question is often asked and is answered in either the comp.lang.c or
comp.unix.programmer FAQ, as I recall. The general answer is that, no,
there is no foolproof way to do this in all conforming C implementations,
and, no, there is no foolproof way to do this in most UNIXes. The FAQ
suggests methods you may pursue if you only need an algorithm which works
most of the time.
Under NEXTSTEP, you can ask the main bundle for its name. I do not know if
this method is foolproof.
Add to all this the possibility of programs modifying themselves
dynamically or a dynamic filesystem (e.g., deleting the program in
question), and you can see that a general solution is quite difficult.

Thanks for the responses I have read both but I will make a generic reply
basically you need another computer of the same type with the appropriate
ethernet cards to use Nexts remote debugging facilities. To bad with the
price of old Nextstations there use is remote debuggers would be nice.
This is the way I understand it according to Rakesh Dubey from Next.
Considering what I spent on my first machine this is not and option for a
student hacker :(
Is there anyway to fix the file system when you crash the kernel
This is the most troublsome problem since whith a kernel crash I need too
fix the file system which takes a long long time on only a 2 gig drive
making the already unpleasent task of rebooting a Unix system onerous :(
I can live with the reboot but not the disk fixing.
Can I trap a unix signal in the kernel and synch the disk??
I really have no idea what the kernel does when it catches a signal from
kernel code. Catching Unix signals from user code I understand what goes
on in the Mach kernel when theirs a problem I don't. I probably need to
read more books : (
Second Axel Haberman suggested the use of printf() can I use a lot of
print()'s and when the ROM monitor comes up they are displayed there or
should I watch the console till the driver crashes. Basically I need more
info on the ROM monitor. And the limits of is capabilities. For one even
thoug its called the ROM monitor its certianly noot in ROM on a Intel
machine ? Thus it would seem to me a very nasty pointer could crash the
kernel and take out the ROM monitor in the process ? I don't quite
understand memory protection in the kernel I do know that inside a single
user program a wild pointer or overun array bounds does not crash the
program as long as it points to memory already in the program or
unallocated (I think) leading to the classic nasy pointer bug. Which
considering I did numerical programs I became used to seeing. Talk about
strange unsolved bugs run over and array bound.
Agian thanks for the replies I think I'm about ready to do some crashing
just stay away from SCSI disk drivers to begin with : )
Especially if it's possible to synch the disk before rebooting.

Robert, this took some while to work out who it might be directed at, as
you didn't include a References header, or quote the original article.
Here's the key line from my response:
> stream = NXOpenTypedStreamForFile("stringTableArchive", NX_READONLY);
NXTypedStream is required for use with the read:/write: methods; as
implemented by any NeXT supplied class. This is the quickest and easiest
way to create an archive copy or load an archive copy of any object (with
3.2 Developer).
NXStringTable also supports readFromFile:/readFromStream:, which puts the
object out in a readable format. If you want to use that, then:
NXStringTable *aStringTable;
aStringTable = [[NXStringTable alloc] init];
[aStringTable readFromFile:"filename"];
So long as you have sent:
[aStringTable writeToFile:"filename"];
Somewhere else.

Last week I wrote a small app, implementing a very simple sound view. If you push
the button, the window grows and you can see it,... pushing the button back shrinks
the window. This is the action method that implements that behavior:
- toggleSoundView:sender
{
NXRect newWindowFrame;
[noteWindow getFrame:&newWindowFrame];
if (largeWindow) { // Make smaller
NX_HEIGHT(&newWindowFrame) -= NX_HEIGHT(&soundViewFrame);
NX_Y(&newWindowFrame) += NX_HEIGHT(&soundViewFrame);
[[noteWindow contentView] setDrawOrigin:0.0 :
NX_Y(&originalViewSize)];
[noteWindow placeWindowAndDisplay:&newWindowFrame];
largeWindow = NO;
}
else { // Make bigger
NX_HEIGHT(&newWindowFrame) += NX_HEIGHT(&soundViewFrame);
NX_Y(&newWindowFrame) -= NX_HEIGHT(&soundViewFrame);
[[noteWindow contentView] setDrawOrigin:0.0 :
NX_Y(&originalViewSize) - NX_HEIGHT(&soundViewFrame)];
[noteWindow placeWindowAndDisplay:&newWindowFrame];
largeWindow = YES;
}
return self;
}
and this is the relevant part of awakeFromNib:
- awakeFromNib
{
// Get the original window size
[soundView getFrame:&soundViewFrame];
[[noteWindow contentView] getFrame:&originalViewSize];
largeWindow = NO;
....
I hope this will help.

As far as I know, on all implementations of cc that I have used, argv[0] is
supposed to return the name of the program. For example:
myName.c:
#include <stdio.h>
main(int argc, char * argv[])
{
printf("Hello, my name is %s.\n\n",argv[0]);
}
When this program is run, it will output the following:
Hello, my name is myName.
Hope this is what you were looking for.

The main problem is that you would need a way to access to current list of
registrated filetypes or class extensions.
Having them in a secret filearchive is nice...but not as helpful as having
them on the web.
If Scott (stepwise) is not interested then I could suggest making it part
of the developers corner on EduStep.

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME

REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different

Chicago NeXT developers - to 80k + Sign-On Bonus+ Bonus
My client is currently establishing a new office in Chicago, and is
aggresively hiring NeXTSTEP developers for a large NeXT based project.
This billion dollar company needs to hire at least 12 NeXT professionals
to assume lead roles in the development of a new financial based system.
You will develop applications in a state-of-the-art NeXT environment that
includes NeXTSTEP 3.3, Sybase, EOF, PDO and AppKit, and will include
OpenStep and WindowsNT.
Due to the current market demands for good NeXT developers, my client will
pay up to 80k or more, for top developers, as well as, a sign on-bonus, a
1996 bonus and excellent benefits.
I would particularly like to talk to NeXT developers who are currently
working for banking and finance companies in Chicago, as the renumeration
package available is specifically aimed at that type of candidate.
If you feel you have the necessary background, contact me today.
If you were considering looking for a new position after the New Year,
this may be the right opportunity for you, as my client will arrange start
dates in January.

because the detection of uninitialized variables is frequently done only in
the optimization phase of the compiler. it has to do with flow diagrams of
compiled code for optimization. you don't need these diagrams if you're not
doing the opt, so you don't get the warning.

mouse pointer tracking is not at all rock solid, as far as i can gather.
i don't think i'm alone in occasionally getting pointer anomalies
(text cursor outside a Text view; normal cursor in a text view) from
various unrelated applications.
i was trying to debug a similar annoying bug in my own
application. occasionally it would temporarily lose track of the
current cursor type. i eventually gave up, because the app seemed
to be doing everything it should be; something was being lost
somewhere in the system layer.
i'd blame NEXTSTEP.

Subject: Big PC problems - can't log in, many crashes, help! *URGENT*
Date: 13 Nov 1995 17:28:02 +0100
Organization: University of Bergen
Message-ID: <487rmi$bkq@alf.uib.no>
Hi. I really need help to get my machine into some sort of
useable condition - this is driving me crazy.
Symptom: I cannot log in to my normal user account.
Background: see below...
In the 1 or 2 weeks I've had the new machine, the system has crashed
on average once every 24 hours. I thought I had finally localized
the problem to excessive dps errors, but this morning something new
happenned. When I logged in, most of my docked autostart programs
didn't start. They tried and failed (no message in console or in
/private/adm/messages). Most programs would not work at all -
they started to launch and then died without any warning. A few
did work - Preferences, WorkspaceMangler and Edit. Terminal
would not work. No commercial/3rd party apps worked. When I
tried logging in as root everything worked (I'm here as root now).
I tried rebooting, exiting the windowserver, etc etc, nothing helps.
The only change I made in the system was to install Calliope.font
in ~/Library/Fonts last night. I tried building the afmdir without
affecting anything. I tried removing the font (the only 3rd party
font on the machine) but no change. I checked all permissions,
ownerships, etc in the entire system - no problems. I still can't
start apps as myself, only as root. As root I su'ed to my own home
account and fired up gdb to try a few apps. Opener and FrameMaker
both gave similar errors:
Opener:
Memory Access exception on address 0x60155 (protection failure)
0x5095cdb in dbSwapInLeaf ()
FrameMaker:
Memory Access exception on address 0x1e171d (invalid address)
0x5095cd2 in dbSwapInLeaf ()
Trying to start them from a terminal (su'd to my home account)
gave a segmentation fault and a bus error, respectively.
The worst is, after trying this I was _completely_ unable to log
into my home account (i.e. my regular user account, not root).
I get the background colour and then I get a new login screen.
No error messages.
I'm really getting upset at this constant failure and crashing
of NSfIP - this PC has crashed/paniced/shown "weird" behaviour
more times in two weeks than all the years I've used a NeXT
computer. I wondered if it was hardware, but then the root account
would also be flakey, no? I'm ready to return the entire machine
and get something else (what, Dell? Sun? HP? DEC?) before it
makes me crazy. All of you with PC's - is this _normal_ behaviour???
Here's my config, hard and software (I tried booting with default
config, no change - still can't login):
Intel Endeavor mainboard, Triton Chipset, PCI 2.2 controller,
AMI BIOS, ISA/PCI bus (10MHz/60MHz), 256kb pipeline burst cache,
16MB RAM (2x8MB SIMM), on board floppy, 2x on board EIDE/ATA/ATAPI,
on board parallell, Matrox MGA Millenium 2MB WRAM. Not sure where
the serial controller is - probably on the mainboard, Quantum
Fireball 1.0GB EIDE hardisk (512 block size, multiple (8) sector
transfers enabled).
Wait - /private/adm/messages reports PCI controller version 2.10,
not 2.2 (that's what technical support reported they use...)
I have (in Config.app) configured the folowing:
Display: MatroxMGA2064W 1024x1280/75Hz, RGB:256/8
Mouse: Serial Mouse (v3.33)
Network: none
SCSI: none
Sound: System Beep Driver (v3.30)
Other Devices: Serial port 1&2 (v3.33); ISA/EISA Bus (v3.30);
PCI Bus (v3.30); PS/2 Keyboard (v3.30) (actually its a Winlose keyb);
TTY Port server (v3.33); On board Paralell port (v3.30)
There are no config conflicts. I have enabled (in BIOS and in
NeXTSTEP) power saving (sleep/suspend after 30 minutes inactivity)
for both system and monitor. I have ppp2.2 as a loadable kernel
driver to run ppp, otherwise there's nothing strange. I've
installed MiscKit and "productivity" software I use daily (between
crashes :-), not much else. I'm really wondering what this might be.
I've installed the 3.3 patch1 package several days ago, but it didn't
seem to affect the systems reliability or speed (I hear others find
the system faster after patch?), it kept crashing. I have not (yet)
run the post-install script (don't know which is appropriate - should I
go into every executable on the machine to find what uses posix
libs??? This is crazy. Do I need the new posix lib to replace
the 3.2 version I have? probably not.) I have English, Swedish and
French installed as language packages on the system.
As far as I understand NeXTstep, the login program starts the
windowserver and Workspace - all from one central copy - I
don't understand why it works as root but not as myself - the
permissions seem correct and this is something that just
"happned" - the only thing I've done is surf a bit on the
Web, download Calliope and install it in ~/Apps and the Calliope
font in ~/Library/Fonts. I tried the app but it quit because
I haven't installed Sonata.font yet. Could this be some sort of
virus (I'm guessing wildly now...)
Any/all suggesstion are more than welcomed - please e-mail me
directly, I haven't time to wade through news.

The login problem I've solved - something corrupt in ~/.NeXT
was enough to cause a lot of headache - why it didn't allow
login with missing or standard values is beyond me. As
for being buggy, several have indicated that this is often
hardware glitches and that NSfIP is very stable, given
that the latform its run on is also stable. I'd still
appreciate advice to keep crashes to a minimum, and am
considering having a new mainboard installed while it's
still under garantee (at the least I'll get PCI 2.2 controller
instead of 2.1...) Tips/hints/ideas as always are welcome via e-mail.

I see and I understand, but on the other hand I think that this is very
useful warning and in most cases this warining indicates an error, so it
will be very useful to detect it regardless of the optimization.

The compiler can only detect those types of situations when you turn on the
optimizer becuase those warnings depend on "variable liveness" information
which is generated by one of the earlier phases of optimization.
This hopefully was mentioned in the documentation....

Hello Folks!
I am attempting to query a IXRecordManager using IXAttributeQuery.
From the documentation that I have, it seems that IXAttributeQuery
will accept queries in the form of (const char *)'s that are valid
Indexing Kit Query Language statements.
My application manages to generate this query:
and(eq(word "louse"))
from the Indexing Kit Query Language specification, it seems to be
a valid statement.
gdb manages to indicate that the query is null-terminated:
(gdb) display queryString
2: queryString = {"and(eq(word \"louse\"))", '\000' <repeats 7882 times>"}
BUT, my code...
if ( (query = [[IXAttributeQuery alloc] initQueryString:
(const char *)queryString andAttributeParser:nil]) == nil ) {
fprintf(stderr,"Error accepting queryString\n");
exit(-1);
}
exits due to a returned nil. This seemingly indicates that
IXAttributeQuery has found a syntactical flaw in my expression.
Is there some syntactical arcana that I am missing?
Thanks for any help!

Take a look at /usr/gnu/bin, Filemerge uses _this_diff and diff3. If they are lost,
just make a link to the directory where your favorite GNU diffutils reside.

Tomas,
In case of NOT using optimization, variables will be initialized when
declared, typically with a ZERO value.
So it is a proof of intelligence of cc, to NOT warn you.
But i don't know, where is the sense of this initialization in case of
not using -O.

You should verify that gnu diff is in the place where FileMerge
expects it:
/usr/gnu/bin/diff
I know of a case where this was removed and caused similar (DPS)
messages in the console. Out of the (3.3) box, GNU cmp, diff3, sdiff
and sort get installed there too, but I don't know if FileMerge
needs those too. Unfortunately the path (/usr/gnu/bin) is
hardwired into FileMerge, so they _must_ reside there.

hello,
I would like to define a menu cell with a title which is not
a plain string (it has greek letters inside). My first idea
was to use an icon (using the "initiconCell" method) for the cell
title. However the documentation says that "you should never set
a MenuCell's icon".
Is there a workaround?

This is just a guess from the error message presented, but it's
possible that ixbuild does some sort of checksum on EPS files that it
indexes and it expects them to come up with unique sums. The two EPS
files that you have may have the same checksum.
Try opening one of them in Edit and adding a space somewhere,
or perhaps changing a comment. Then try the build again.
Just a guess. Please repost the results of trying this.

In order to have the information required to provide those warnings, the
compiler has to perform some fairly expensive (in both space and time)
preliminaries in the optimizer. It doesn't really make sense to compute
this information in order to provide warnings but not use it to also
perform code optimization.
If you want those warnings, compile with "-O -g -Wall".
What's the problem with that?

With an app of mine that does mouse tracking, I have observed that
mouseExited events sometimes fail to be processed by the app when the mouse
leaves the tracking rectangle. I spent a lot of time trying to figure out
why, and eventually gave up, putting it down to flakiness in the tracking
mechanism.
Missing mouseExited events could account for the behavior we sometimes get in
many apps where the cursor changes when entering a certain area of an app,
but fails to change back when leaving the area.

AACCKKK!!! NO! NO! NO! NO!
This is *not*, I repeat, *NOT* true!
Variables that are neither `static' nor `extern' have no defined value

Joe,
You might find the Integer object of the Computer Algebra Kit useful.
Feel free to ftp a copy of the software from the web in my signature and
see whether it can do something for you. I'll continue to provide
versions of the Computer Algebra Kit for the former (it seems, from NeXT's
web) NextStep operating system, in addition to versions for other OS-es.
I've been told by aficionados of OpenStep marketing that my objects are
not "OpenStep compliant", and after working a while with the Foundation
Kit, I think we'll keep it that way, which might or might not be an issue
for you as a NeXTStep/OpenStep developer.

Message-ID: <48aofm$6m2@opal.southwind.net>
I am wondering if there is a freely available version of the Mathematica
Notebook Interface for Nextstep.
Specifically I am interested in there block structure with its cut and
paste methods. Their notebook interface is not standard to the Appkit but
I find it a very powerful interface and would like to incorporate it into
other projects. I like how the copy method just highlights the block bar
and the nesting of code blocks etc. For interpreted block structured
languages this "editor" feature can make writing/debugging code much
easier. I find it one of the joys of writng Mathematica code.
It would also be convenient for page design programs ala TeX. Which has a
inherent block structure. Also one thing not directly available in
Mathematica would be to to allow the linking of a block to a wide variety
of services. Thus one could seclect a block and if its on the receiving
end of a gui button show the link to the gui button ala IB. Thus instead
of links to no GUI objects disappearing in to formless object in IB it
will follow the link to the actual code. This linking can also be extended
to include links similar to thos in HTML. This would allow the follwoing
of dependencies in code in the same manner that one would search the web
for a given topic. Another possibility would be a powerful interface that
replaces the current Unix shell CLI programs and scripting languages.
If there is not one I will write Wolfram Research concerning this and see
what they will do. I have already called them and was given the correct
email address to make the request.
If its already available please send me information on how to obtain it.
If not if other people are interested in using this interface or would
preferably like it in the MiscKit then please email me and I will tell
Wolfram Research that there are several interested parties.

Let me know when you get this working. I'm trying to get perl5.001m
installed for the same reason on both m68k (3.2) and Intel (4.0alpha).
Can't get a configuration that will actually make correctly. I get
duplicate names in the linker, omitted information in doio.c, sigh!
I would really like to find a configure.h file set up for these for
next. Or a tarred compressed fat binary?

[bla addSupplement:"SupHelp" inPath:path];
Where SupHelp is the directory name in the appropriate language wrapper
path is the path name of the directory name
ie. directory name will be SupHelp
and path will the the parent of where SupHelp lies.

Anyways I've used NXAttachPopUpList to hook up my Button subclass to the

I think this has something to do with the IBEditor being set to the

I took a look at this out of curiosity. All it seems to say is don't try
running a version of an app built with a Foundation library newer than the
one installed on your machine. This is true for any shared libraries -
even when I was writing shlibs on VAX/VMS. So what's the problem ?

Keywords: indexing kit, handles
Hullo!
I have some question regarding the NeXTstep Indexing Kit, particularly
the IXPostingExchange protocol compliant classes.
First of all, the NeXTstep documentation is very vague regarding
handles and postings. I am trying to create a posting set with
through cursoring a searchKey into a IXRecordManager. After obtaining
this set, I'd like to be able to create a new set that has all of these
postings in it, but indexed by a different attribute (which is present
in each of these objects).
I am trying to do some like this:
/* allocate posting set */
wordset = [[IXPostingSet alloc] init];
/* allocate and localize cursor on word attribute */
cursor = [[control recMan] cursorForAttributeNamed:WRASTRWORD];
/* enter key and length into cursor object */
[cursor setKey:(void *)searchKey andLength:STRINGLEN(searchKey)];
/* put all matching postings (by handle) in posting set */
[wordset formUnionWithPostingsIn:cursor];
/* allocate posting list for access to complete stored objects */
postingList = [[IXPostingList alloc] initWithSource:[control recMan]
andPostingsIn:wordset];
/* free current cursor */
[cursor free];
/* free current posting set */
[wordset free];
/* allocate and localize cursor on aLink attribute */
cursor = [[control recMan] cursorForAttributeNamed:WRAINTLINK];
/* allocate posting set for aLink searches */
linkset = [[IXPostingSet alloc] init];
/* put all aLink attribute handles into posting set */
[linkset formUnionWithPostingsIn:cursor];
/* intersect these postings with keySearch posting list */
[linkset formIntersectionWithPostingsIn:postingList];
I am not sure that this code is working in the way that I had intended
it.
I have another question regarding the IXPostingSet
formIntersectionWithPostingsIn: method. This method seems to be very
powerful, but it is perhaps not as general a tool as I would like. I
would like to take two IXPostingSets that each have WRAINTLINK
attribute handles in them, and I would like to remove all WRAINTLINK
*values* that are not present in both sets. I thought that
formIntersectionWithPostingsIn: would work initially, but it doesn't
seem to operate on values but strictly on handles.

I've put a code segment below to show you how to do this, but remember
that there is a bug for bundles with NXHelpPanel - it can't make use of
Help.store files (generated by compresshelp) - this was reported in V3.2.
So you must copy in the entire (uncompressed) Help directory to the
bundle's .lproj, before the below will work:
- help:sender
{
id bundle = nil;
id helpPanel = [NXHelpPanel new];
char path[MAXPATHLEN+1] = "\0";
bundle = [NXBundle bundleForClass:[self class]];
if (![bundle getPath:path forResource:"English" ofType:"lproj"]) {
return nil;
}
[helpPanel addSupplement:"Help" inPath:path];
[helpPanel makeKeyAndOrderFront:self];
return self;
}
Best things,

[ Posting to international and national german newsgroups as a
crosspost. Sorry for the language...
]
I am using a Linux system as my ISDN gateway. This system is
running isdn4linux, but has no useable display or keyboard. I am
working at my Nextstation running Nextstep 3.2.
isdn4linux has an informational device /dev/isdninfo that can be
queried for the current status of the ISDN lines managed by
isdn4linux. I have written a RPC service isdn_svc, that reads
input from /dev/isdninfo and informs the caller about the
current line status. At the nextstation, an ISDN monitor
application polls isdn_svc and plays a sound at status changes.
This is backwards for two reasons: Firstly /dev/isdninfo became
a blocking device with the latest update. Reads from
/dev/isdninfo will block until the state of any line changes.
Secondly polling the Linux system creates a small, albeit
unnecessary base load on my network. This does not scale well.
I would like the Nextstation to be a RPC server with the Linux
system (possible more than one) sending RPC updates to the
server whenever the line status changes. I would like the RPC
server to the integral part of the Nextstep application, but I
have not the slightest idea if this is feasible or a good
design.
Since the RPC server as well as the application kit have ready
made event loops, I cannot easily merge them both.
-> Will I have to roll my own [ NXapp run ]?
-> Or how do I integrate a RPC server into my application?
-> Is there ONC RPC support in some ObjC library? Has anyone
written some interface class for ONC RPC handling
authentication, calls and the like?

A couple of days ago I posted an article reporting the problems I was having
getting Autodoc working. Thanks to a number of people I now have a working
Autodoc.
Step 1.
Get the sources for perl5.001m and unpack them.
Step 2.
Run `Configure'.
When asked for a `hints' file, specify `next_3'.
From then on, just type <return> to accept all defaults.
(Don't worry about some `WHOA' messages -- just type <return>).
Step 3.
Make, test and install perl. On my NS3.3/FIP machine, all the
tests succeeded.
Step 4.
Follow the Autodoc installation instructions.
And that's it!
I don't know what the changes are between perl5.001 and perl5.001m, but
I do know that Autodoc didn't work with the 5.001, and does work with 5.001m.

Under 3.2, I edited the Makefile by hand in the src directory and did a build all in that

There is a SMALL non-feature... strftime under NEXTSTEP doesn't understand %T,
so you need to search for %T in the source and replace it with %H:%M:%S
There are two, perhaps three occurances...

Emacs_for_NeXTstep.4.1 is 19.28.2 and it's full GUI :-)
It's on Peanuts as:
<long path or just cd next>Emacs_for_NeXTstep.4.1.NIHS.b.tar.gz

It does this automatically if you manage to fry the disk and it has to

During the coding and debugging phases, building with -O requires more
time which is significant for large projects.
Debugging optimized code can be confusing and difficult because of what
optimization can do.
So it's much nicer to avoid optimization until the code is stable and
testing is about to begin, but then you discover the initialized variables
which would have been nice to discover during the earlier debugging phase.
But we can't have it both ways, it seems :-(

Maybe you could be a little more specific - It seems pretty
straightforward to me. Each more recent version of Foundation is backward
compatible with applications developed with the previous versions.
Applications using Foundation can only run on systems using a version of
Foundation greater than or equal to the version they were developed under.
What were you expecting? And what do you mean by "OPENSTEP hell"?

(Somebody replied to my previous message in this thread, saying that he
wanted public explication/justification on my cursing of the
OpenStep/FoundationKit guys in this thread, because "what's wrong with
that NeXTanswer?".)
I posted a follow-up to a discussion between two NeXT employees in the
"OpenStep spec changes" thread about OpenStep changes or incompatibilities
between various implementations. I referred to a NeXTanswer that shows
you the complicated situation already for a relatively small product like
Foundation Kit, meaning that you can expect something in OpenStep.
The cursing (sorry, nothing personal) was inspired by the statements "I'm
not sure what's going on" of the one person, and "has anyone perchance a
public domain implementation of fork() for Windows" of the other one.
But there's more to it. I'm sort of pissed off by Foundation Kit, which
is why I did that reply in a fit of anger. They don't care about compatibility
*at all*, "we're gonna redo everything" seems to be the motto. You can put
my own Computer Algebra Kit objects nicely in a List or HashTable, archive them,
or print them in a debugger, or send them over the net with PDO, or add them to
a Stepstone Dictionary, SortedCltn,etc. for that matter. But making it work
with the Foundation Kit ? I think that's not the concept of Objective C. When
I started developing my objects - and the idea goes back to '90-91 - I
was sort of enthused (actually, I'm still) by the idea of *mutually*
compatible software components.
All this rewriting is no good. The idea of Objective C is to *insulate you*
from massive code source modifications, like having to run a script over
your source that converts the whole thing. (that's why I think the poster's
comparison "even on the VAX/VMS it was the same" is *correct*, but
object-technology was exactly supposed to *do* something about it
(and it does !))
I guess all this means is: no Computer Algebra Kit objects in OpenStep.
Well, supposedly my objects are not compatible, but me thinks THEY ought
to conform to the standard (as defined in Stepstone's and NeXT's *SPEC*
sheets - don't these documents have any authority?) +new, -copy, -free,

That's fine if you are only supporting one language but Bundle's are

My experience correlates 100%.
I tried taking NX_MOUSEMOVED events, but true to the docs this flooded
the event queue making performance unacceptable.
What I ended up doing was setting up DPSAddTimer with an interval
of oh, say, 0.25 seconds, and doing a [window getMouseLocation:&loc]
in the timer routine. This is gross but seemed to work well for
what I was trying to do (similar to Netscape auto-displaying the
URL of the link under the cursor).

And I explained that I don't see what's so complicated about that
situation: All newer versions of Foundation are backward-compatible
with previous versions.

Well, not _quite_ everything. But the changes that were made going
from Object->NSObject were made for a reason. Using Foundation lets
you write code that is (IMHO):
Easier to understand
More robust
Simpler
Unfortunately, the mechanics of the new autorelease memory management
(among other things) require some fairly low-level changes in object
implementation. And, all the objects have to follow the same policy.
Hence the changes from List->NSArray, for example.

And, once you convert them to inherit from NSObject and implement the
NSCoding protocol (fairly trivial), they'll be fully compatible with
FoundationKit.

I guess he wasn't responding to my post - I don't remember mentioning
VMS. Oh well, charge ahead anyway:
The design of Objective-C had some serious problems in terms of
managing object deallocation, object distribution, and exception
handling. Foundation represents the first re-thinking of Objective-C
in _years_. By comparison, the rate of change of other languages (C++
in particular) has been staggering. And how many C++ vendors provided
a tool to help you migrate your code from C++ 1.0 to 2.0?

Well, I'm sorry that you feel that way. One goal of Foundation is to
increase the overall quality of the Objective-C programming experience.
I do hope you'll try it before you brush it off. It's actually not
that hard to make the transition, and the benefits are real.

This one:
[From DevTools/11_Compiler/Compiler.rtf]
Unlike most other C compilers, GNU CC allows you to use -g with
-O. The shortcuts taken by optimized code may occasionally
produce surprising results: some variables you declared may not
exist at all; flow of control may briefly move where you did not
expect it; some statements may not be executed because they
compute constant results or their values were already at hand;
some statements may execute in different places because they were
moved out of loops.
I know, this does not happen frequently. I saw it only once so far, but it
took me a while to find out that the strange gdb behavior was due to use
-g and -O together.

I'm not 100% sure what comes with what distributions and what's been
installed on your machine, so this might not help.
You should have a directory called /NextApps which contains an application
called Librarian (everybody has this). Run the app.
At the top of the window is a bookshelf of on-line manuals. If there's
something called NeXTAdmin just click on it, and in the text area below,
enter a topic and search. There's also a way to view all titles, then
browse through the manual on your own.
If there is NOT a NeXTAdmin manual in the bookshelf, you'll need to find
it and add it. Leave Librarian running (move the window off to the side,
you'll need it visible later) and switch back to your directory listings.
Look in the directory /NeXTLibrary/Documentation. You should (hopefully)
see a directory named NextAdmin. If you do, highlight this, then drag the
icon (just above the list) onto the bookshelf of the Librarian window
(you'll see a ghost image appear in the Librarian when you've hit the
right spot). Then, continue with the searching/viewing as above.
OK - if you don't have NeXTAdmin in your /NeXTLibrary/Documentation
directory, then you hopefully have the NeXTStep CD for your machine. Put
it in your CD ROM Drive - it will appear in your browser window. On this
disk, you should find a /NeXTLibrary/Documentation directory with the
Admin manual. You can drag it directly onto the Librarian window as
above, it'll just be slower cause it's on CD.
As far as the Internet NeXTStep sites, there are a few. Probably the best
starting point is http://www.next.com
If any of the above advice sounds unreliable it's because I used to own a
NextStation (sold it about 18 months ago) and I'm only just now getting
back into working with one so I'm relearning most everything about them.
I've received enough help from people on USENET that I'm always happy to
help.
Good luck!

So, has anyone sucessfully compiled gnu's new fortran compiler, g77 under
NeXTStep? Several people in our group would like to have a fortran compiler
available, and I've heard that g77 works, even if it's not terribly well
optimized yet.
Anyway, if somebody has gone through the effort, could they upload a binary to
Peanuts or orst ??? I'd really prefer not to install the whole gcc source tree
if I don't have to ... Thanks!

Yep;-) It's taking an address of a typecast expression that's not allowed in
ANSI C -- you can only take the address of an `lvalue' and a typecast
expression is defined as an `rvalue'. The new compiler is a little more
stringent in its syntax checking than the old 3.0 compiler, which was based
on a pre-2.0 version of gcc.
Rewriting it to "(void **)&" should make it syntactically valid C.
[interestingly enough the 3.3 compiler (based on gcc 2.5.8) still allows
--admittedly sometimes useful-- constructs like
char *cp;
((int *)cp)++;
without a beep. Unless you turn on `-ansi -pedantic', that is.]

Message-ID: <48j82s$6bm@news4.digex.net>
Hi all :)
Well, I got the 'fix' to record from the DSP... It is weird...It
is included int the little app I included below...
In short this is it:
SNDStartRecording(originalSoundz, 1, 1, 0, SND_NULL_FUN,
SND_NULL_FUN);
//this part makes DSP recording work
originalSoundz->dataFormat=SND_FORMAT_LINEAR_16;
That originalSoundz...guess that properly does what sndConvert does
not...
Welp, I still have a problem...
Although I can now record from the DSP, what I need to do is 1)
record from the DSP, 2) play a snd file, and 3) manipulate what is
being recorded... all at the same time.
Now this used to worked just fine when I recorded from the codec
instead of the DSP. But now I cannot get all 3 things working at
the same time.
To record and play at the same time I must use a SNDWait(0); but
this doesn't let my program to continue executing so I can keep
manipulating the incoming data.
However, if I get rid of the SNDWait, then a sound will play, but
no sound will record...
Is there a way to get all three things happening?
//TestProgram
#import <sound/sound.h>
#import <stdio.h>
#define SECONDS 10.0
main (int argc, char *argv[])
{
int err,cntr;
char answer='y';
SNDSoundStruct *originalSoundz;
SNDSoundStruct *newFormatSoundz;
if (argc != 2)
{
printf("usage : recordfiletest file\n");
exit(1);
}
/* 1)
this is normally a long sound that goes for minutes and is
used for biofeedback...I.E. replace moo.snd with
the path to a sound more than 10seconds long to see
the problem
*/
SNDPlaySoundfile("moo.snd",0);
err = SNDAlloc(&originalSoundz,2*SECONDS*SND_RATE_LOW,
SND_FORMAT_DSP_DATA_16, SND_RATE_LOW,1,0);
printf(SNDSoundError(err));
printf(", SNDAlloc originalFormat...\n");
/* 2)
usually this would be recorded for several minutes until
the user stops recording
*/
SNDStartRecording(originalSoundz, 1, 1, 0, SND_NULL_FUN,
SND_NULL_FUN);
//***************this part makes DSP recording work
originalSoundz->dataFormat=SND_FORMAT_LINEAR_16;
if (err) fprintf(stderr,"recordfiletest : cannot allocate
buffer\n");
printf("recording...\n\n");
/*
will wait for all play/recording sounds to finish before
executing further down...
*/
/*
SNDWait(0);
printf(SNDSoundError(err));
printf(", SNDWait...\n");
*/
// 3) Here I would be doing manipulations on the data being
// recorded...but this getchar illustrates the
// problem more simply. The problem is that if I dont use
// the above SNDWait, nothing records...and if I do, I
// cannot do manipulations I need while recording and

while (answer!='n')
{
printf("If you want to do work while recording dont hit
N...\n");
answer=getchar();
if (answer!='n')
for(cntr=0;cntr<10;cntr++)
printf("While recording&playing I've done
%d other things\n",cntr);
}
err = SNDWriteSoundfile(argv[1], originalSoundz);
printf(SNDSoundError(err));
printf(", SNDWrite originalFormat...\n");
if (err) fprintf(stderr,"recordfiletest : cannot start

Hi,
We're looking to assemble a document imaging system, which we would like
to integrate tightly with an EOF app. We need the following components,
as separate pieces, or an integrated solution.
Scanner software/scann objects-- Software to drive the scanner.
Image processing /Image filtering-- All the standard image processing tricks.
CoDecs-- compressors/decompressors that perform popular compression algorithms.
should work either on popular file formats or on NXImages.
OCR-- If a standalone app, should integrate tightly with previous components,
but preferably available as NS objects.
Image Database-- Since EOF is how we will access the images, a standard
Oracle or Sybase RDBMS is preferable. But it has to deal well with
images, work well with some type of storage media that is capable
of storing 10-100 GBs of data, depending on compression, and serve
up the images very fast.
We would prefer to have all of the above pieces live in the NS world, but
we will also look at Solaris or NT solutions having APIs that are easily
accesible from the NS side.
Information pertaining to any of the above pieces appreciated.
Thanks.

I haven't done this for a while, but I think a good, (stolen from
code above...) simple example is this:
defineps GetWin(|int *win)
currentwindow win
endps
I *think* currentwindow takes zero parameters and pushes its
result on the stack. By putting the name "win" after it, it
associates the name "win" with the return value.
Similary,
defineps Multiply(int x,y | int *z)
x y mul z
endps
would multiply x and y and return the result in z.
I hope this helps,
Steve

Well, you compile with "-g -O -Wall" until you've fixed all of the
warnings, and then you can compile with just "-g" if you have problems
debugging the optimized code "-g -O -Wall" produces.
It's never bothered me much, but then I'm familiar with what a compiler
does when optimizing. I normally pay enough attention when writing code in
loops that the compiler doesn't have to move a lot of invariant expressions
out of the loop, which is typically something that throws people who aren't
expecting it...

You could try running the RPC server code in a thread, or in
a seperate process. Then communicate with your App using other
more Appkit friendly means such as DO ([NXConnection runFromAppKit]),
file descriptors (DPSAddFD()), or shared (and locked) data.
I hope this gives you some ideas!

Hello,
I have a question about initialization of an object which returns
another object.
According to the documentation
"Beacuse an init... method might return an object other than the newly
allocated receiver, or even return a nil, it's important that programs
use the value returned by the initialization method ...."
Now, what if a have two objects ObjA and ObjB ( hierarchy of objects
ObjB:ObjA:Object ), and the init method of object ObjA returns another
object. In object ObjB i have the following code for init.
- init
{
self = [super init];
...
code to initialize this object
...
return self;
}
How does ObjA (which is messaged by [super init] )know to return
an ObjB rather than an ObjA?
Any help would be appreciated. Thank you in advance.

Does anyone have an idea on how to correct this ? If I launch IB through

Hello,
I was just wondering, wether this is a bug, or wether I'm just to
ignorant to get this done:
I'm using a font which features some of the symbols described in the
NEXTSTEP Symbol Encoding Scheme (positioned correctly) and I want to use
them, but:
NeXT's symbol encoding scheme seems to map everything to the Symbol Font!
E.g. If I type a <trademark> character, the Symbol.font is used instead
of my custom font. I can' even remap this. The only solution seems to me
not type <trademark> but <icircumflex> and remap this to my symbol font.
Unusable to me. This all prevents you from using other symbol fonts,
doesn't it?
Why shouldn't it be possible to use a font, which lacks e.g. the
<icircumflex> character but features the definition for <trademark> and
use the <trademark> charakter when I type <trademark> ond does nothing
when I type <icircumflex>.
The point is: I know that the Adobe encoding scheme only features 256
different characters, but why can't these characters be used? If a font
lacks one of the characters NeXT wants in its encoding scheme, and
features another which NeXT wants in its symbol encoding schema, it isn't
used, because NeXT switches automatically to the Symbol.font. (Even if
the character is mapped correctly!)
Am I doing something wrong with my handcreated Adobe fonts, or is this a
standard behaviour?
Best regards,
Boerny (hoping that the encoding scheme is better in NS4.0).

comp.sys.next.* newsgroups
==========================
news:comp.sys.next.advocacy
This is the "why NEXTSTEP is better (or worse) than anything else in
the known universe" forum. It was created specifically to divert lengthy
flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at
ftp://ftp.stepwise.com/pub/Next_Announce_Archives
Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be

REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different

I'm currently looking at the different classes of the NeXT system (just for

available (so, my knowledge is not very deep so far). Right know I'm playing
around with typed streams.
According to the documentation the following line should be correct :
NXTypedStream *stream;
stream=NXOpenTypedStreamForFile(aFileWIthPath, NX_READWRITE);
Unfortunatly, after running the prog in a shell NeXT returns the following
error message :
Untrapped arror #8000
Could somebody please give me a hint what this errormessage could mean ? Or
how to make the above line work correctly ?
Thanks in advance for any help ...

more specifically, i'm working with the "Renderman Companion". i'd
like to know how to take the examples (even the simple ones) and use
them more or less as is (i.e. w/ri.h and the NeXT interface/appkit)
instead of hacking them into the N3D libraries (which does seem to
work, but since it's a hack, i'm not exactly sure what i'm doing).
for example, the simple 'display a polygon' example on p.18 refuses to
compile on my machine if i just enter it and compile using cc. i get
'Symbols not found' (or something like that) for all the Renderman
stuff after the RtPoint (RiBeing, RI_P, RiWorldBegin, RiSurface,
RiPolygon, RiWorldEnd, RiEnd) and i'm not sure why.
since some of the Renderman library does not appear to have been
N3Dized (e.g. Constructive Solid Geometry), i'd like find a means to
get this to work.
thx

My understanding was that parts of it were going to wind up
in the foundation kit, and the rest of it (the higher levels)
were going to quietly fade away.
That's based on ancient info, though. I too would like to
have a more up-to-date (and more specific) idea of it's fate.

Date: 20 Nov 1995 16:43:58 GMT
Organization: UMass-Lowell Computer Science
Message-ID: <48qb8e$ne6@ulowell.uml.edu>
Hello -
Finally got an older cartridge tape drive running on an '030 cube.
Most of the supplied utilites work and a couple of little things I've
written work fine. However, I have one little problem..
I would like to use dump(1) and restore(1) with it.
This particular tape system uses a SCSI<-->QIC interface and can only
deal with fixed length blocks, specifically 512 bytes. This seems to
breaks dump and restore.
Before trying to write Yet Another Version of dump and restore, does
anyone have a pointer to source for an existing version that could be
used as a starting point?
Please, use e-mail. If there is interest, I'll summarize back to the
group.
Regards,
Mark

Currently that's not happening. I'm only getting an initialize when I
explicitly message the class.
I'd like to have something that's messaged upon that classes loading

Date: Tue, 21 Nov 1995 09:40:22 GMT
Organization: High Performance Sports Ltd.
Message-ID: <489629906wnr@hps1.demon.co.uk>
I've been programming in NextStep for the last few months
and so far I've adhered as closely as I can to the MVC
paradigm. I understand the reasons behind it when dealing
with something that offers multiple views of complex data,
but I'm wondering if I'd be better to just bin it.
I'm mostly building database front-ends which need to do
quite a bit of validation, and whose main function is to
get information with some fairly tight constraints from the
user. In other words, there is a lot of 'business logic'
which I feel ought to be in the 'business objects' and not
in the 'user interface objects' (practically, various
delegate methods in my controller files).
It occurs to me that the most natural way to go
ahead would be to have my 'business objects' linked quite
tightly to UI objects. Thus, for example, if I have a
(non-UI) object called a 'Customer', I
could send it messages like '[myCustomer runDialog:self]
and it would pop up the appropiate kind of panel for
setting its attributes etc. This would then let me build
fairly sophisticated views where a double-click on a line
of text representing an object would result in a panel
being run, without the UI needing to know what kind of
object it was being sent to.
There are lots of other cases where this might be
useful - messages for validation, objects asking
the user for missing information they needed at various
points, informing the user beforehand about changes to
related objects.
Are there any problems in such an approach?
And what is the cleanest way to give my business objects
access to the IB objects it needs? #import myController.h
and make sure they are there? Multiple, reused nib files?
Palettized inspectors? I've not done any of these yet, and
I'll want to put my business objects in a whole family of
apps with the maximum reusability.
Could anyone gice me some guidelines on how they deal
with this sort of thing?

This is the exception TYPEDSTREAM_CALLER_ERROR; meaning that it wants mode
to be either NX_READONLY or NX_WRITEONLY. See the Librarian page for more
details, and other error returns.

Organization: University of Houston
Message-ID: <48t3ai$5u5@masala.cc.uh.edu>
Keywords: Next postscript instead of ghostscript?
For LaTeX users, there is a very nice utility on the net called psfrag.
See, e.g., on the usual CTAN server at
ftp://ftp.shsu.edu/tex-archive/macros/latex/contrib/supported/psfrag/
The main purpose of psfrag is to embed full latex constructs
(including math equations) in a previously created eps file. This is
very convenient, for example, if say an eps file of a plot or a diagram is
created as usual in Nextstep and then one wants to add a complicated math
expression at a particular location on the figure. Or if you want the
fonts on your plots to match the math fonts used in the LateX document.
psfrag is nice but its use requires a full installation of ghostscript.
"gs" is called from a perl script to perform the necessary changes in the
eps file.
Can a kind Nextstep savvy soul help all us NextTeX users by looking at
this perl script and checking if the builtin postscript in Nextstep can be
used instead of ghostscript? I very much prefer to avoid installing
ghostscript if I can help it.
Thanks a lot.

Umm, sorry, I don't *think* you can what you're wanting with the "standard"

- What is the correct way of capturing and displaying the TIFF file generated

camera:(etc, etc) method but cannot figure out the right way to call it. It
starts the renderer, finishes, and then the image is lost.

This seemingly strange compiler behavior (no set-use checks when
optimization supressed) makes sense when you look at it from the compiler
writers perspective.
The flow graph analysis necessary to do the set-use checks is a central part
of an optimization pass, and unecessary just to generate unoptimized code.
So it makes sense to skip this check rather than repeat the expense of flow
graph analysis to check for a single kind of warning.
I'd love to know the rationale for initializing automatic variables to zero.
Is there any way to turn off that behavior?

The switch from Object to NSObject and from the "old" way of memory
allocation to the "new" way (enforced reference counting; object
responsibility) is certainly quite a jump ... but if, like us, you were
working on a very large project (several projects, in fact) you _might_
have found that you had come to the same conclusion as NeXT - that
something fairly radical was needed.
I see their move as very positive as (from our perspective) the choice is
to rewrite everything anyway, rewrite in SmallTalk or C++ (no thanks), or
suffer from the after-effects of bad memory management. The fact that we
are getting a "free" port to Windows (in some form) is quite a plus ...

At some point in time, any design breaks down. Either you admit it and fix
it, and go through the pain then, or you persist with the same design (and
shortcomings) until it catches up on you. I respect NeXT for admitting
they didn't quite get it right the first time and making a very good
attempt at curing the problem without leaving their clients in the dirt

All I can say in defence of NeXT on this basis is that their OpenStep
standard has been accepted by Sun and GNU, and as such has wider "market"
support than Stepstone. Your code will still work on NeXT's OpenStep
implementation - the shlibs are still there from 3.3.
Hopefully we will see a computer algebra kit on OpenStep - I personally
would think it a missed opportunity.

Excuse me for such a stupid question, but I must ask.
I used a stripped binary of this program as 'eject' which would eject a

thought it worked under 3.2, but now when I run it Fiend crashes with a

I need to have a Text object which has a slightly differently
idea of what constitutes a word for purposes of double click

need the characters '[', ']', '<', '>' and '/' to be dealt with
as standard alphabetic characters rather than as punctuation.
Thus, double-clicking on any character of [EXAMPLE] would select
the entire word plus the brackets. As near as I can tell from
the documentation, I need to reset the Text objects click NXFSM,
and everything should work. However, the only function
for creating one of these finite state machine has a dozen arguments
and no documentation to speak of. Does anyone know of any example

setting fixed length block does not require sources to dump/restore but is an

Sorry, but the NeXTdimension hardware predates your 'power saving' monitor
design by several years. Activating the power-saving features on newer
monitors requires switching off combinations of the vertical and
horizontal sync signals. After flipping through my old hardware notes, it
looks like there's no way to safely do this on the ND board (e.g., the
hardware hooks simply aren't there) without breaking something else.
I'd be suprised if it could be made to work anyway, as the power-saver
features in the monitor are normally tied into the TTL level HSYNC and
VSYNC inputs. These aren't used with the NeXTdimension, which generates a
composite video signal.

I am doing a build on NEXTSTEP for a tool. Since I have many subprojects I
have a top level common header directory in my project called include. In
the Makefile.preamble I add a -I$(PRODUCT_ROOT)/include, and this works
beautifully.
However when I move this to PDO, even though it seems like the same symbol is
defined in NeXT's makefiles, this fails to create the correct -I argument.
It only inserts a single ./ instead of the long ../../ necessary.
Is there another symbol for the top of the source directory that can be used
in a Makefile? Is there a better way to do this? I know I can put in the
hard path, but it's so inflexible.

When I read this "allegation", I was skeptical because I have been caught
too often by uninitialized local variables containing "garbage", not 0 :-)
So I wrote a small test program and confirmed that there's no obvious
initialization of local variables either with or without optimization.

Wait and see. I also think you're unfair to Stepstone here. They
may not have had the money to build a factory and manufacture
workstations, then decide that's not the market, then build an OS and
then decide there are already too many OSes.
They had a vision and ideas, and these ideas are withstanding time. As
a matter of fact NeXT is trying to do now what Stepstone said back then.
I'll take any bet that the Stepstone concepts will continue to exist LONG after
autorelease, retain etc. disappeared with the company that is now
aggressively forcing their developers to adopt it (and will not succeed).
>Hopefully we will see a computer algebra kit on OpenStep - I personally

I'm not asking for much. Please don't remove Object from the "Industry
Standard Object Layer", you could say I'm begging.
"But then we will have two hierarchies of objects !" Well, you should have
anticipated that... I have a feeling this "transitional" period is going to
last for a while :-)
All this autorelease pool stuff might be exactly what your domain
needs, but it's not what I need in a domain like symbolic computation
that is notorious for its memory management requirements. So if they
want to give their business customers objects for bigint, bigfloat, fixed
size integer arithmetic, polynomials, matrices etc., well don't act like
an elephant in a shop of china, and tell me I have to rewrite a
complex 45,000 line system. And if you don't want these objects, well some
other "standard" might emerge, acceptable for people from all sort of domains.
I suggest making NSObject a subclass of Object. Let's see whether they
will listen, and let's see who's unreasonable here.

Date: 23 Nov 1995 00:27:12 +0100
Organization: University of Bergen
Message-ID: <490bkg$2o2@alf.uib.no>
I know that Adobe supports a larger character set than NeXT, and
have had problems getting certain letters (mostly composites,
zcaron, scaron, etc). A friend had tried recoding to put the
special letters in question within the 255 range for use on NeXT,
and it works. The problem is that the keyboard has to be completely
reprogrammed because of the displacement caused in the coding.
My question is: is it possible to recode a part/subset of
standardencoding to enable use of special letters (by removing
others seldomly/never used) without messing up the entire
keyboard? I looked a bit in Thinking in PostScript but
I'm not too good at the technical/programming side of things.
Please e-mail replies.

The problem wasn't the code, but Fiend. Version 1.4 doesn't crash.

If the bundle doesn't load (rld_ errors), you've stripped too many symbols
from it and/or the main executable, and the dynamic loader can't resolve
everything. Make sure you've set APP_STRIP_OPTS to $(DYLD_APP_STRIP_OPTS)
in Makefile.postamble.
If the bundle loads but crashes, you've likely got a problem with
uninitialized variables or something similar. Make sure you get zero
warnings when compiling with "-g -O -Wall".

Hi All,
While writing the NEXTSTEP driver for the data acquisition ISA card I
discovered the bug in the DriverKit IODirectDevice class. The return value
of the currentCountForChannel: method was always '1', regardless the
actual value of the DMA word count register. This is valid for the 16-bit
DMA channels and probably also for 8-bit DMA channels. This bug also
affects the method isDMADone:, which does not work too.
The only work around is to read the value directly from the DMA word count
register.
I have NEXTSTEP 3.3/Intel (of course) with the latest 3.3 User patch
installed.
I sent report about this bug to bug_next@next.com too.
Best regards,

while the correct transformation is
Page=0x0
Addr MSB=0xc0
Addr LSB=0x00
The problem in the NEXTSTEP code is that only lower 16 bits (up to A15)
are shifted right. The correct approach is to shift right lower 17 bits
(up to A16). Therefore the transformation is done wrong if the bit A16 in
the physical address is one.
The same error is in reading the DMA address, so if you read and write DMA
address via DriverKit methods everything looks good, but the data goes to
the different place than your driver expect.
The only work around is to set/read the DMA address for 16-bit channels
manually using direct access to the DMA registers.
I would like to thank to Eric Norum <eric@skatter.USask.Ca> for checking
my conclusions.

Date: 24 Nov 1995 09:19:57 GMT

Message-ID: <4942nt$5jq@cisun2000.unil.ch>
I am trying to use a NotificationCenter to get messages from my remote
server. I know about the example with EO and distributed objects; I'm trying
to do something a little differently.
The main problem is that NSNotificationCenter doesn't recognize my server
which is posting notifications as the same server I registered to send
notifications.
I register the client on the server end essentially like this:
<caution pseudo-real code>
- (oneway)registerClient:client
{
myMutableArray = [clientArray addObject:client];
}
When I register the client with the server it's via the proxy so I do:
- registerWithServer
{
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(displayStatus:)
notificationName:SIMUpdateStatus
object:remoteServer]; <---- IMPORTANT
[server registerClient:self];
}
Then in the server it does this:
[clients postNotificationName:SIMUpdateStatus object:self]
I have to make remoteServer be nil in order to receive any notifications. It
seems that remoteServer != [notification notificationObject]. Why not?
Thanks for any info, known bugs, etc. Should I override isEqual? Shouldn't
this work in a transparent distributed environment?

The bundle actually loads fine in both instances - zero compile errors, no
rld_ errors, no missing symbols. ALL variables have default values.
Globals are declared "volatile", it's just the Intel version compiled with
-O mostly crashes at a random point ...
It's been suggested to me that this is a byte-alignment problem, which I
tend to agree with - as, *sometimes* the bundle will load fine (say after
I've added something new to the code) - is seems totally 50-50 as to
whether a bundle compiled under Intel with -O will load. It's also
extremely difficult to debug this sort of thing.
Even more strange is that the same bundle compiled for HP-PA or SPARC with
-O runs just fine.
Me thinks it's an Intel specific issue ... that'll teach me 8-)
Thanks anyway.

I don't know of any software which attempts to perform generalized Mach
exception handling. I've done some work towards that for the beta release
of CrashCatcher 2.0. However, since I've had zero customers ask for that
functionality, there isn't any demand to justify the development costs.
There are several choices for handling Unix signals. There's the original
ObjectError.m and CrashTrap which are freely available on the FTP archives,
and CrashCatcher, a commercial product of ITS. If you're interested, feel
free to contact me via email.
------------------
By the way, if by "stack over flow", you're referring to something like:
void
bad_function()
{
int a[10];
a[123] = 0; // very bad idea!
}
Nothing will detect or help with that type of error, because you've
corrupted the stack in an undetectible fashion. A debugger will often be
unable to perform a backtrace. That type of code causes the most difficult
and unreproducable bugs to occur, so avoid large automatic arrays or
alloca() if you can.

The Foundation doesn't use fork() for any public API, so we don't
need fork() on NT, but customers may have use for it, so it'd be
nice to make it available. We know how to implement it to get
80-90% of the functionality you expect out of fork(), but it's
non-trivial and we don't have time. fork()+exec() functionality
they have, but fork() alone is sometimes useful, as for, say, a
test execution tool which forks off a child for each test so as
to not dirty the execution tool's memory with the test (and each
test runs in a "pristine" environment).

You don't say what kind of compatibility you want...
It was decided to "redo everything" (like List -> NSArray) so
that it was quite clear when you were using old stuff and when
you were using new stuff (and could take advantage of new behaviors).
The old classes couldn't be retrofitted to get all the new
functionality, and even if possible, that may have changed some
subtle behavior you (or anybody else) were unknowningly depending
on.

You can still do all of that. List, HashTable, Storage, continue
to exist. I can add HashTables to an NSArray, and archive it and
unarchive it, send it over new DO, or old DO to a limited extent
(limitations due to old DO, which we cannot change).
(I'm talking about the Foundation in OpenStep 4.0 here; I'm not
familiar with the 3.3 foundation.)

Object-oriented programming does not insulate you from changes
in the API, and doesn't claim to. It does help to insulate from
changes *and choices made* in an underlying implementation, but
often fails to do that, too (I'm thinking of examples in Eiffel
and C++, as well as Objective C here).

Well, that's a choice you can make. The term "spec sheets"
is a bit of a misnomer. Even the OpenStep "spec" is not a
specification in the (stricter) software engineering sense.

I need to display actually hundreds of strings in a camera view and can live

So an approach ala Hershey Fonts done with Ri* qrman calls would be fine.
This most definitely has been done before, I am unwilling to repeat the effort.

If you just want to compile the examples from "The RenderMan Comapanion" pretty
much as is (that is ignore 3D Kit and anything else NeXT specific), then get
Larry Gritz' BMRT (which will give you the ri.h and a library for the RenderMan
API (which will build the RIBs from the C source).

That is not the behavior, maybe you are thinking of static variables?
Check this out:
#include <stdio.h>
void test1()
{
int j;
j = 10;
printf("%8.8x %d\n", &j, j);
}
void test2()
{
int j;
printf("%8.8x %d\n", &j, j);
}
int main()
{
test1();
test2();
}
pizza% a.out
bffff908 10
bffff908 10
So j has the old value from test1() -- thus autos are not initialized to
anything.

Here is my recipe:
first I have a small script which I run:
------------------------
if (-f $1'.c') then
cc -o $1 $1.c -lMedia_s -lNeXT_s
strip $1
$1
/usr/prman/prman $1.rib
/NextApps/Preview.app/Preview $1.tiff
else
echo 'file '$1'.c not found'
endif
-----------------------
Then my C-progarm looks like:
-----------------------
#include <ri/ri.h>
RtPoint Square [4] = {{.6, .6, 0}, {.6, -.6, 0}, {-.6, -.6, 0}, {-.6, .6,

Hmm. The Intel architecture has the least-restrictive alignment requirements
of any of the architectures that NEXTSTEP runs under, with the HP being the
most restrictive. (If I remember correctly.) Therefore, I would be surprised
to find that this was an alignment problem.
On the other hand, the Intel is little-endian...byte ordering is more likely to
be an issue.

Hi,
I have a version of Simple.app compiled (probably from NS3.0 days) and it
displays the torus with some light.
However, when I compile a copy of the sources, the new app displays the torus,
but no noticable light in the scene, and the torus is hardly noticable. The
saved rib file still contains lightsource reference, though.
So it seems like something has changed. Do you have any pointers for me to
investigate? I try this under NS/N 3.2.
Btw, is there a more appropriate newsgroup for 3dkit/renderman?
Thanks, Juergen

Thanks for all the info about font conversion - the best thing
I found was FontConvert, a free conversion tool with a bit of
font-debugging capeabilities, very nice.
I've been reading the tutorial/cookbook (Adobe) trying to
find out the best way to get the few extra letters supported
by PS but missing in NeXTs vision of standardEncoding...
I've found many good tips, but have no idea how to make them work.
I do notice that NeXTs fonts include several of these letters
already (scaron, zcaron, eth, etc) encoded as .notdef (-1).
However, NeXTs Keyboard.app (somehow) allows the use of these
unencoded characters...! How is this done? Could I simply
substitute (f.x.) zcaron for currency and have zcaron
automatically useable at the same encoding vector as currency?
What about non existant (but possible) lettters like ccaron
or cacute - could I simply define them in the afm file and
include a definition in the composites secition at the end
of the afm file? How do the font files and afm files
encodings interact - which takes precedence, and how does
Keyboard.app manage to change this without changing the
fonts?
Lastly, it looks like program 18 in cookbook would work
for me if I knew how to use it - I get the example to work but
have no idea how to apply it to actually modify an
installed font file to enable these extra letters. I know
that there must be an elegant and simple way, but not
enough to know what that is :-)
Before you start sending RTFM type comments, I _have_ RTFM
and all the on-line docs. That doesn't mean I understand them :-)
BTW - there doesn't seem to be any table (3.3 Intel) in the
on line docs describing NeXTs StandardEncoding. Keyboard.app
has some info, unortunatley everything is in hexadecimal
and Adobe font encoding vectors are in decimal... Where
did I leave my calculator...?
Please e-mail replies, when I _finally_ get this to work
I'll make some nice flashy package/document explaining
how to customize font encodings. With all the international
NeXT users I'm surprised noone has done this before...

Hello,
I am having a very strange problem. Within a factory method, I use
system( "rm -r ..." ) to delete a directory, then check the return
value to see if the deletion was successful (0 is success, non-zero is
failure). For testing, I created a directory in /tmp owned by root
that I cannot delete. The absolute path is given to system(),
i.e. system( "rm -r /tmp/dirname" ).
The problem is this. It works fine when I run the application under
GDB, it returns non-zero to indicate that the "rm" command failed.
But when not running GDB, system() would return 0, even though the
directory is not removed!!! I am stumped since I can't use GDB to
debug this. :-(
Help?

Software development provides some of business's most lurid horror

double or triple their budgets are common. So are stories of projects
that were outrageously late and those that never work at all. There are
many views to this problem.

Natural perhaps if you're abandoning MVC, otherwise not.
The more tightly bound (coupled) _any_ classes are, the less reusable
they are, since the coupling makes one class difficult to use without
the other.

Better to have a controller class named <EOClassName>Controller (e.g.
CustomerController). When the user clicks the text, use
NSClassFromString (or objc_getClass) to get the Controller class, then
tell the Controller class to inspect (or whatever) the object.

You might want to implement EOF's prepareForDataSource method in your
EOs. This only covers validating the whole object before saving it
though; in the more general case, you need something else. The best
solution to general (attribute level) validation is unfortunately
quite complicated with EOF, but worth doing. I can send you more
details if you like, but basically you need to do 2 things:
1. Subclass TextFieldCell and override isEntryAcceptable:, to return
YES or NO according as whether the EO considers itself valid, then
have your subclass poseAs:TextFieldCell.
2. In the set methods for your EO attributes, implement the
appropriate validation logic. If invalid, the reason is stored as a
string in an ivar, and can be requested for display in an NXAlertPanel
by your isEntryAcceptable: method.

Stick with MVC. Sometimes the going gets tough, but it's worth it in

I have it compiled ok on NS3.3, all I did was ensure that -ansi and -posix

Subject: f2c? Why not use g77?
Date: 27 Nov 1995 01:36:45 GMT
Organization: University of Saskatchewan
Message-ID: <49b4nd$hrv@tribune.usask.ca>
I've been using f2c on the NeXTSTEP machines here for the last couple
of years. I can send the shell scripts I use for unpacking,
compiling and installing f2c to those who are interested.
Now, though, I'm switching over to a `real' compiler - g77
Getting g77 working under NeXTstep is pretty easy -- at least if
you're used to working with GNU software distributions......
1. Get the source for the latest versions of gcc and g77. As far
as I know, the latest versions are g77-0.5.17 and gcc-2.7.1. These
are the versions I worked with.
2.Unpack the gcc sources:
tar xf gcc-2.7.1.tar
This will leave all the sources in the directory gcc-2.7.1
3. Make a symbolic link (you must do this *before* unpacking the
g77 stuff)
ln -s gcc-2.7.1 g77-0.5.17
This makes unpacking the g77 sources easier.
4. Unpack the g77 sources:
tar xf g77-0.5.17.tar
Because of the symbolic link, this puts the g77 sources in with the
gcc sources -- which is where they have to go.
5. Change to the gcc source directory:
cd gcc-2.7.1
6. Decision time! If you've got f2c installed, you might want to:
rm -f f2c-install-ok
touch f2c-exists-ok
If you don't have f2c installed, you can skip this step. If you do
have f2c installed, you really ought to have a look at the README
that comes with g77.
7. Configure the compiler:
./configure
8. Build and install the compiler:
make LANGUAGES=f77 g77 install
9. Wait, and wait, and wait. There will be a whole bunch of
messages printed (when installing headers, the compiler complains about
*every single* NeXT header file that contains `#import'), but things
should finally end up in the right places.
10. Try compiling your fortran programs!

news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.
USING NEXTANSWERS BY FAX
To use NeXTanswers by fax, call (415) 780-3990 from a touch-tone phone and
follow the instructions. You'll be asked for your fax number, a number to
identify your fax (like your phone extension or office number), and the ID
numbers of the files you want. You can also request a list of available
files. When you finish entering the file numbers, end the call and the
files will be faxed to you.
If you have problems using this fax system, please call Technical Support
at 1-800-848-6398. You cannot use the fax system outside the U.S & Canada.

Steve, What Fentek (my company) does is to sit down with the clients hash
out their conserns and write it up. After both side have an understanding
THEN send it to your lawyers! And yes you had better send it to your layers
to make sure that everything is phrased correctly or if something happens
you will be hung out to dry unless you have built up good will and your
client wants to work with you again. There really is no secret about
contracts only about building good will and an understanding with your
clients and subcontracters.

There's one thing about g77: It doesn't work neither with

doesn't work for NEXTSTEP/HP-PA and Sparc.

Andy:
I would suggest that you use the rmdir() and unlink() system calls
when removing directories or files. This is a more direct route
than using the system() system call.
I don't have the time so I can't go into the major details as to why
this is better but here is a "quick and dirty" excerpt of how you may
want to work your problem. Give it a try:
#include <stdio.h>
void main(int argc, char *argv[])
{
int errno = 0;
char errorstr[BUFSIZ];
if ((errno = rmdir("/tmp/dirname")))
{
fprintf(stderr, "We have errno %d\n", errno);
perror(errorstr);
}
exit(0);
}

While I appreciate the instructions on how to compile g77, I'm afraid I
don't agree with the description, 'pretty easy'. I have had some
experience compiling GNU software, and I still have not been successful in
compiling either gcc-2.7.1 or g77 on my HP running NEXTSTEP, nor was I
able to find any one else who had had any better luck, when I asked the
Net for help here in comp.sys.next.programmer. The problem is, that
unless things have changed, the GNU software configure scripts don't know
about HP machines that run NEXTSTEP, and I am not a sufficient guru to
explain to them what to do.
Until then, I am sticking with f2c - at least it compiles.

Date: 27 Nov 1995 16:28:35 GMT
Organization: University of Saskatchewan
Message-ID: <49covj$k8b@tribune.usask.ca>
I installed the 3.3Patch on all the NEXTSTEP machines here a couple of
weeks ago. This morning I tried using MallocDebug on one of my application
(which uses the Foundation Kit).
Every time I clicked on one of the MallocDebug display buttons (New/All) the
MallocDebug application would quit and the MallocDebug window would disapper.
To try and see what was going on, I ran:
gdb /NextDeveloper/Apps/MallocDebug.app/MallocDebug
Here's what I got:
Reading symbols from /NextDeveloper/Apps/MallocDebug.app/MallocDebug...(no
debugging symbols found)...done.

Reading symbols from /usr/shlib/libsys_s.B.shlib...done.

So, what's happening here? Does MallocDebug not work after the 3.3Patch
is installed? Does MallocDebug not work with applications which use the
foundation kit?

It's indeed a problem. And, just cheating configure doesn't help. One
had to create a bunch of files in ./config/ that define how the
compiler had to work on the specific platform with the specific
OS. From my layman point of view, this had to be more or less a merge
between the according files for HP-UX/PA and NEXTSTEP/Moto or Intel.
Anyway, I can't do it, NeXT won't do it yet, and the FSF has no
interest, too. Therefore, no NS/HP or Sparc user will ever get g77 or
gpc ;-).

Local variables get placed on the stack, so what was already on the stack
determines the default value. When you first run the program, there's a
reasonable chance that your automatic variables will receive a 0
hexadecimal value (which will be the number zero for integral variable
types).
Compiling without optimization means that more temporary spill areas and
possibly unneeded local variables will be created (instead of being
overlapped togther), so you typically are a lot more likely to see more
variables start at 0.
Of course, depending on any of this is why programs have bugs with
automatic variables!

Subject: DPSAddTimedEntry doesn't trigger autorelease
Date: 27 Nov 1995 19:38:30 GMT
Organization: University of Saskatchewan
Message-ID: <49d43m$1i0@tribune.usask.ca>
For the past day or so I've being trying to track down what I thought was
a memory leak in one of my applications. The application displays, in
real time, some data acquired via distributed objects from a server talking
to an IEEE-488 digital oscilloscope. The objects returned from the server
have NSObject as their ancestor, and use autorelease.
The heart of the application is a method called from a DPSTimedEntryProc
function. The method gets a couple of autoreleased waveforms from the
digital oscilloscope server and displays them.
The problem I was having was that the application would grow, and grow, and
grow, then occasionally shrink again (as shown by the VSIZE column of
ps alx).
After some poking around, I found that the problem is that the DPS time
entry events don't seem to trigger
the autorelease cleanup -- the cleanup would occur only when I pressed
some button, or selected some menu item in my application.
Maybe this is a well-known problem, but it was new to me!
The fix is simple -- just add an autorelease subpool to the timed-entry
method:
===================================================================
- tickHandler
{
NSAutoreleasePool *subpool = [[NSAutoreleasePool alloc] init];
if (xyMonitorViewX != nil)
[xyMonitorViewX acquireDataFrom:scope channels:@"C1":@"C2"];
if (xyMonitorViewY != nil)
[xyMonitorViewY acquireDataFrom:scope channels:@"C3":@"C4"];
[scope armTrigger];
if ((xyMonitorViewX != nil) && [[xyMonitorViewX window] isVisible])
[xyMonitorViewX display];
if ((xyMonitorViewY != nil) && [[xyMonitorViewY window] isVisible])
[xyMonitorViewY display];
[subpool release];
return self;
}
static void
tickHandler (DPSTimedEntry tag, double now, char *userData)
{
[(ScopeController *)userData tickHandler];
}

*sigh*
Well, I hereby eat my words. I posted some code, and asked why it was
causing a panic. Someone suggested that I get Fiend 1.4 and see if it
still happened. I did, and when the program didn't crash and my machine
didn't panic, I ASSUMED that Fiend 1.3 had been the problem.
Today, my code crashed (paniced) my machine again today (why I still
don't know). At any rate, my apologies to David Lambert for blaming Fiend.

Hi,
why didn't you ask this question on comp.lang.ada? It would have
been much more likely to get a satisfactory answer there. But anyway
you are lucky and I am reading comp.sys.next.programmer too. I am the
one who ported the GNU Ada compiler (GNAT) to NeXTSTEP. You can find
the binary distribution on our ftp server:
ftp.uni-stuttgart.de in
pub/programming/Ada/GNAT/gnat-2.07-i386-next-nextstep3-bin.tar.gz
GNAT is based on the GCC backend technology but does not produce any
intermediate C code if that is what you meant with native.
The distribution contains a readme file and if you follow the instructions
carefully there should not be any problem with the installation. Others
than me were able to get it right, so it should not be too difficult.

Ok, well I think this has finally been fixed. My thanks to David Lambert
for helping me fix the code, even after I had mistakenly accused Fiend of
being the reason for the panics.
Anyway, the revised code for eject.m is beneath the .sig. it hasn't
crashed once, and David figured out why the other code was (something
about not releasing the memory it was using).

YES, there are serious problems with such a approach.
This is the voice of bloodied experience in this case.
If your business objects are tightly tied to the GUI, they cannot be reused
in several other contexts. For instance, in a batch or command line program
or a back end server app. Or in a batch test driver. Or in an app that has
a different kind of GUI.
Do you really want to repeat all your testing by hand each time?
For instance, if your model objects can stand alone, untied to any
particular type of interface, you can build multiple front ends, say one for
WebObjects, one for OpenStep, even X, curses, or command line ones. You
can also reuse your business objects in other contexts and other apps more
easily.
Don't mix them up. Your business objects shouldn't even know their
controller's exist.
Another warning sign is putting up alert panels inside model objects to
report errors.
Don't do it. Use exceptions or another way to report the error to the caller
and let the caller decide what to do about it (put up a panel, beep, log to
a file etc)
Its a little more work, but much more flexible (and thus reusable).

If you think about it, you can get the same effects without violating the
"separation of concerns" principle. For instance, you can use protocols,
categories, delegation, exceptions and notification in several different
ways to add object specific UI behavior, but still keep the model objects
separable from a specific UI.
> And what is the cleanest way to give my business objects
> access to the IB objects it needs?
Don't give them direct access to the GUI. just don't. Use a controller of
some sort.
Good luck.

I was replying to a previous poster who claimed that gcc had that behavior

gcc doesn't initialize automatic variables.

Interest from me, but no money - we're a very small leisure company saddled

I am working on a General Ledger object and a generic 'business modelling'
framework for building detailed forecasts of cash flows, balance sheets etc.
This would let the businessman build models very simply and take care of all
the accounting side, so you could concentrate on the model of your sales,
customer behaviour, workflow or whatever.
I'd be very happy to chat about any possible overlap.
I'm kicking off in Python as that is portable between my windows system at home
and Next at work, but I hope to cover objC once it is prototyped.

And this sounds like a good enough reason to have a gcc flag which forces
initialization of automatic variables to unlikely values such as MAXINT etc.

Does anyone know if the '040 NeXT machines implement the M68040FPSP
floating point software package as provided by motorola.
This is a package that is run after a reset on a 68040 to provide support
for unimplemented floating point instructions through the '040 exception
handling. See the 68040 databook for more details.
I am wondering if these routines are implemented in the ROM, or in
the mach kernel, and also, if NeXT has made any changes from the motorola
version. Any and all details concerning implementation on the NeXT '040
systems would help me.
Also, do the '040 machines use the NMI for anything other than breaking
into the rom monitor??
Does anyone know if NeXTStep uses the MMU status register or the PTEST
instruction?
And, where is the ROM mapped in memory? I want to take a look at it!
These questions are rather technical, and require information that NeXT may
have never made public. If you are a engineer with NeXT, or know one you can
forward my questions to, it may help!

I found the easiest way to accept DO messages while doing long

the request in a fifo. Perodically in the loop, check the queue.
This gives you more control over the mechanism, so you don't have to

You can also use Portable Distributed Objects, whereby you can with little
pain vend an object from one application for use by others, anywhere on the
network.
There's also the user-visible object linking stuff, but I can't recall how
that works (I've never used it in any of my programs, and haven't had a need
for it as a user in many months.)

NeXTSTEP was designed with this in mind. Services are one of the ways
to advertise capabilities of your program to other programs.
Communication is done via the pasteboard, distributed objects or mach
ports. The latter won't work under OpenStep as they are
NeXTSTEP-dependent.

I am pretty sure they aren't in the ROM. My justification for this lies in
the library of "improved" 040 math routines that was floating about in the 2.x
days (it's still on Peanuts somewhere). It advertized that the improvements in
the library would be included in 3.0.

Thanks Chuck. You were correct, alignment wasn't the culprit - it seems
to be a rather nasty struct with some horrid little bit-fields, I believe
it's the way they are initialized that is causing the compiler flags -O or
-O2 to screw up ... (many thanks to Art for pointing this one out).

Matija,
The readRTFDFrom: method is used to replace the contents of the Text object
with text and images that were saved in a file using writeRTFDTo:.
writeRTFDTo: serialises the contents of the Text into one file - NeXT's Text
object does not provide support for creating .rtfd files.
If you need to replace the contents of the Text object from an .rtfd file,
use openRTFDFrom: instead.
Should you need to be able to create .rtfd files using Text, please email me
directly as we have done this in our word processor CedarWord.
Regards,
Paul Heffernan, Product Development Manager.

I cannot see any reason why you do not place each print request in a separate
thread. That would leave the normal event queue free to receive further
requests, provided your DO object uses oneway messages to implement the
printing. The misckit already has support for such threading (?).
But maybe I am out of my depth here.

Depends on the "one archecture", of course.
In the case of the base arch being NeXT hardware:
df #
Kbytes
used
------
293523 NeXTSTEP 3.3, Quad-fat developer libraries
311494 NeXTSTEP 3.3, Quad-fat dev-lib, plus EOF
350800 NeXTSTEP 3.3 patch 1, Quad-fat dev-lib, plus EOF
That's how much is used up. Add on whatever extra you want.
I believe the above numbers include about 1meg used up by
the swapfile, and you'll probably want more than that...

Organization: Psychology, Carnegie Mellon, Pittsburgh, PA
Message-ID: <wkjQwSe00iWP82Su1c@andrew.cmu.edu>
I have recently started using MouseX and seem to be encountering some problems.
- I'm running MouseX on a 3.2 mono slab.
- I installed the complete basic and developer archives.
- I EXACTLY followed the installation instructions.
- Xfe is currently using ALL default preference settings.
- I am currently able to build/develop (I've built emacs, xfilemanager,
ctwm, xpm, etc.).
The problem that concerns me the most is that I can't use the
Cmd+Cmd+Delete or Cmd+Cmd+* key combinations to return to NEXTSTEP.
Every time I try this the Workspace Manager asks me to try to save files
then reboots.
Because I am uable to use Cmd+Cmd+Delete to return to NEXTSTEP, I have
had to exit X in other ways. This requirement is the source of other
problems. When I exit the last xterm, the screen goes black. Under
these circumstances, all I can do is use Cmd+Cmd+Delete, quit the
workspace, logout, and hope that I can see the loginwindow. Each time I
quit X, I'm uncertain if my filespace is clean. Sometimes after an
apparently regular shutdown and reboot, I'll have to run fsck from the
monitor as root to complete the reboot! If this is the price of
MouseX...
If you've been using MouseX, could you answer these questions? (In your
responses you can assume I use X11R5 on Sun5 and DECStations on a daily
basis.)
- What do I need to do to get Cmd+Cmd+Delete and/or Cmd+Cmd+* to work
properly?
- How do I avoid the black screen after quitting X?
- Basically, what do I have to do to safely quit MouseX and return to
NEXTSTEP?
- Can I get "xterm -C" or "xconsole" working under MouseX?
- What should my .xinitrc look like? All my .xinitrc files from SPARC and
DEC machines either fail to start all the clients or cause bus errors (as
seen by "cat /tmp/console.log").
- Would you be willing to send me a copy of your MouseX-friendly .xinitrc?
- Have you been able to get either Tk or STk to work under MouseX (when I
use either, button actions immediately kill all X related processes and
return me to NEXTSTEP).
Please let me know what I'm doing wrong.

When building, PB forks off a make subprocess as in (ps auxww output):
chuck 413 0.0 1.1 1.68M 352K ? SW 0:00 csh -f -c setenv
MAKEPORT MakeError-412-0xaa77c;setenv RECEIVERNAME
MessageReceiver-412-0xaa77c; cd
"/User/chuck/Developer/WorkAreas/CrashCatcher/Examples/CrashDummy";
/bin/make debug
...for "Build debug" in PB. It looks like there's a pair of Mach message
ports being registered for the subprocesses to communicate back to PB with.
For remote builds, I believe that /bin/make then rsh'es the compiler and
linker commands to the remote machine and redirects the output from "rsh"
back through the port to PB.
PB is smart enough to interpret the output from the various parts of the
compiler system and display the messages it does. So, if you set up
Makefile scripts to support your "'compiler' of sorts" and call them from
the standard PB targets, and your 'compiler' outputs messages which parse
the same as those output by /bin/cc, PB should do what you're asking for.

A full install of NS User, Developer, and EOF quad-FAT, including all
optional packages and the GNU sources, takes up ~470 MB. Go down to ~400
MB if you don't include EOF. Of course, you probably don't need to install
*everything* if you're tight on space; you can cut down to 300 MB or so
without losing anything very important.
So don't get anything smaller than a 500 MB drive (you want to have some
space to swap in and 100 MB for user stuff, right?), but I'd recommend a 1
GB, which'll run about $400 US dollars for a good drive today.

something like Quickbase (over $1000). I just want NS Developer to do
what my $84 Visual Basic does, in about 4 minutes flat.
The guy at NeXT was suprised by my question, as if creating a database
with NeXTSTEP was an oddity. He said "Most people use it to access a
database on a Sun running an Oracle database or something". Sorry, I like
NeXTSTEP and IB, but I'm not buying a Sun and Oracle servers so I can
track customers. If I can't get it done with NeXTSTEP, I'll just have to
use VB :(
So what's the solution? Is it really true that nowhere buried in NeXTSTEP
developer is a way to create even the simplest database? And, even more
staggering.. that nothing NeXT sells can do it either? That DBKit and now
EOF do nothing but model data (in a very cool way, no argument there) but
that they are incapable of creating even the simplest 1 table database?
I'm kinda frustrated at this point, as I really want to do some database
programming with NeXTSTEP and would later like to use NeXTSTEP in my
business.. I'm starting to wonder what I have to do.
So in short, if I can't do it with the software I have, what is the best
solution or combination of software to get? (I'll probably be getting EOF
soon, as it seems to be the hot ticket). I didn't think this was a very
demanding task.

I've been following this thread including the response of Alex Blakemore and
Karl Harbour. I often like to put the following methods with my model
objects:
- (int)fillMatrix:aMatrix;
- (void)formatCell:aCell;
I consider this analogous to:
- fprint:(FILE *)aFile;
The file routines don't know how to print all the objects in the universe.
Instead each object knows how to print itself.
As far as separation goes, it seems to me that there are two easy ways to do
this. [1] Subclassing. CustomerGUI inherits from Customer. [2] My preferred
method is Objective-C categories kept in separate modules (i.e., .h and .m
files). For example:
//
// Customer.h
//
@interface Customer : NSObject { // ivars // }
- methods;
@end
//
// CustomerGUI.h
//
#import "Customer.h"
@interface Customer(GUI)
- (int)fillMatrix:aMatrix;
- (void)formatCell:aCell;
@end
Then if I want to reuse Customer in a non-GUI setting I simply leave out the
CustomerGUI module with no ill effects.
Has anyone used this approach? Any comments?

Hello,
I was wondering how to change the target build arch from i386 to i486. When
ever I use PB, the arch is always i386. It seem kind of stupid to me to build for i386
when you can build using i486 and NS will NOT even run on an i386 machine. I
found that when I build using 'make', it is no problem to use the i486 and the
executable runs faster.
Thanks
Charles

Try mSQL at Orst. It is not what you would expect of a commercial SQL
database but it may be enough.

Well I've created a number of DBKit/Indexing Kit databases for custom
purposes, but they do not have the flexibility of what NeXT envisioned
with EOF.

Well if you plan to use your database commercially you probably will want
to use a commercial server such as Oracle/Sybase or Quickbase and use
NeXTStep only as a frontend.

#define strdup NXCopyStringBuffer
is one approach that works. I expect there are others, and probably

Your friend has:
- probable the portable ppp package, where he is trying to port the linux
version to NEXTSTEP (under linux you have to recompile). This ppp version
is already ported and available on severl NEXTSTEP ftp sites.
- and no, there is no way to recompile the kernel, because there are

i have a custom view that i want to contain a slider and a text field.
here is the code i am trying (SliderText.h declares SliderText as a
subclass of View and contains the declaration of initFrame:):
#import "SliderText.h"
@implementation SliderTextt
- initFrame:(NXRect *)frameRect
{
NXRect myBounds;
[self getBounds:&myBounds];
// init viewl
[super initFrame:frameRect];
// create the sliderr
theSlider = [[Slider alloc] initFrame:&myBounds];
[super addSubview:theSlider];
[self display];
return self;
@end
when i run this, i get no sllider in my view (which is in a window -
very simple nib file). if i change SliderText so that it subclasses
Slider (and remove the unnecessary slider initing), everything is cool
- i get a slider.
any suggestions? (i'm going to play some more tonight, not expecting

You gotta configure your server properly. What is Novel 7 database?
Is it Oracle 7 run on Novel? If this is the case please refer to
NeXTAnswer 1897.
I have similar problem (behavior) connecting to Oracle 7 on
NetWare. Server is configured allright. I can connect to in from
Windoza and telnet from NeXT. But when I use EOModeler nothing
happens. I checked with netstat, EOModeler doesn't even create
socket. What's going wrong? Could somebody help?
Thanks,

yes, it was the same code. I though i later posted the code correctly,
but in case it didn't make it out, here it is again:
---- eject.m begins next line ---
#import <stdio.h>
#import <appkit/Application.h>
#import <appkit/workspaceRequest.h>
char *path;
@interface MyObj : Object
{
}
- appDidInit:sender;
@end
@implementation dnt rc;
printf("App did init path=%s\n", path);
[[Application workspace] unmountAndEjectDeviceAt:path];
[NXApp perform:@selector(terminate:) with:self
afterDelay:1000.0 cancelPrevious:NO];
return self;
}
@end
main(int argc, char **argv)
{
id obj;
obj = [[MyObj alloc] init];
if (argc != 2)
{
fprintf(stderr, "Usage: %s path\n", argv[0]);
exit(1);
}
path = a; ("Ejecting %s\n", path);
[Application new];
[NXApp setDelegate:obj];
[NXApp run];
[NXApp free];
}
--eject.m ends previous line --
I compiled this as "cc -o eject eject.m -lNeXT_s -arch m68k" and it works
fine for me. David Lambert pointed out that the previous version was
quitting too soon, so he added a delay to the code, and it has worked
FINE since then.
Also note that the code seemed to only cause problems on MY NeXT, David
tried it on several machines without incident, I believe.
The new version of the code, along with a /bin/sh script I wrote which
does this (ejects disks from the command like) can be found on
ftp://ftp.cs.orst.edu/pub/next/binaries/util/eject.1.1.NI.bs.tar.gz

If you need to use a flag to force that kind of initialization to
occur, then why not just use -O -Wall. Any reference to an
uninitialized variable will be reported. Just having a value put
in by default may mask problems which will bite you when port to
a non gcc environment.
If your code compiles under -Wall with no warnings, it is clean.

I seem to remember that NeXT hacked the compiler driver to handle this kind
of communication with Project Builder over a Mach port. I don't have the
details handy, but if you're really interested in the grit you can check the
source of the compiler driver in /NextDeveloper/Source/GNU/cc/gcc.c and take
it from there (assuming you installed the GNUSource.pkg that came with NS
Developer.)

I have implemented a class called mActionCell, which is actually a Matrix of
actionCell. Since a Matrix is also a View, therefore, in IB, I move a
"custom view" from the palette and rename it to "mActionCell" on my main window,
I have also implemented a menu which can actually add new cells on my window.
It looks something like this
------------
| myMenu |
------------ --------------------------------------------------
| Info | | my window |
----------- |-------------------------------------------------
| Edit | | |
----------- | \ \ / / |
| Add Cell | | ------- ------- |
------------ | | | \| |/ |
| | | | | |
| | | | | |
| ------- ------- |
| icon 1 icon 2
In the diagram, icon 2 is highlighted. When I click the menu item "Add Cell"
again. I will get another icon, "icon 3" and it will become highlighted,
"icon 2" will be back to normal like "icon 1".
What I want to achieve now is when I click "icon 1", I want "icon 1" to be
highlighted and "icon 2" and "icon3" should disappear from the window and leave
"icon 1" only. I have achieved to make "icon 1" to be highlighted, but have spent two days thinking how to remove "icon 2" and "icon 3".
I have tried to use "reenableFlushWindow" and "flushWindow" methods on my
window, but the two icons are still there, although, clicking on them nothing
will happen (not even highlighted anymore).
Can anyone tell me how to remove unused icons image from the screen ?
Thank You very much.

And you may dynamically load kernel modules which is what the NS version
of PPP does. For those of us who'd rather not be compiling kernels all the
time like other UNIX sysadmins seem to frequently do, loadable kernel modules
are a nice feature (yes, I realize they can't do everything that recompiling
the kernel can do).

Problem is that you are getting bounds before the view has been initialised.
The call [super initFrame:frameRect] will set the bounds, so call getBounds:
after. Better still, since you have subclassed the view, you can use the
bounds instance rectangle to initialise the slider - i.e.
theSlider = [[Slider alloc] initFrame:&bounds];
Good luck,
Paul.
P.S. I would not normally put [self display] in an init method - rather call
display, if necessary, in method that calls init.

Message-ID: <49pqks$b3o@ntuix.ntu.ac.sg>
Hi,
I am the developer of PingPong, which is a viewer of PNG pictures
for black and white NS, and available from orst and peanuts. So
far so good. Recently I got complaints from a user, that it
appears to work fine under NS3.2, but not with NS3.3. Lot's of
DPS errors, written to the console, are what I was told.
My question is, did anyone have the same problem or could anyone
else test this for me? I would be very much surprised when a program,
that as far as I know isn't doing anything special, when developed
under 3.2 would not run under 3.3. Sounds weird...

PB uses "make", so if you want to build an i486 target, just add "-arch
i486" to OTHER_CFLAGS in Makefile.preamble. There should be no difference in
the executable produced by PB or by "make" from a shell. If "-arch" isn't
specified, "make" apparently uses what the "arch" shell command returns which
must be "i386" on Intel hardware.
But I'm surprised that this makes any difference at all. How did you
determine that an i486 executable is faster than an i386 version? If the
i486 version really is faster, I don't understand why NeXT wouldn't be using
it instead. Can anyone clarify this?

is it possible in Objective-C to create classes at runtime without

Message-ID: <49rd4s$rcv@news.halcyon.com>
another new NeXT programmer question (boy, getting stated generates
lots of huh?'s).
i have two nib files, one that has lots of controls and the other my
view - is there a way to send messages directly from a control in one
nib file to the view in the other nib file?
since they're in different nib files, i can't connect them directly.
since one end of the connection is a view, i can't instantiate it in
the control nib. right now i'm using a common Controller object in
both nib files and passing the messages through that, but that seems
really cumbersome (have to update in both files every time i make a
change) (and since i'm new at this, i suspect, but don't know, there
is an easier way).

You can't connect them directly, as you noticed, but... rather
than using an ad-hoc controller to go between the files, I
recommend checking out the MiscKit's MiscDistributor object. It
is made for the express purpose of making connections between two
different .nib files, and is on an InterfaceBuilder palette--so it
works in test mode! More information on the MiscKit may be had
from this URL:
http://www.misckit.com/index.html
Note that the MiscKit is pretty useful for lots of other things,
too, so if you haven't looked at it yet, you may find it worth
the effort (and huge download time :-) ).

Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.
Archives are available by ftp at

Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.

For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.
(The original comp.sys.next no longer exists--do not attempt to post to
it.)
Exception to the crossposting restrictions: announcements of usenet RFDs
or CFVs, when made by the news.announce.newgroups moderator, may be
simultaneously crossposted to all c.s.n.* newsgroups.

This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be

To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different

Yes, it can be done. However, it requires you to get very, very intimate
with the runtime system, and then it still is messy. All the necessary
documentation is online or can be extracted from the header files.

Subject: Physical address of NVRAM in black hardware - anyone?
Message-ID: <DJ2vKA.52G@sounds.wa.com>
Organization: Sound Consulting, Bellevue, WA, USA
Date: Mon, 4 Dec 1995 20:00:09 GMT
I would like to know what the physical address is of the NVRAM in my
NeXTdimension. I am referring to the memory which remembers your boot command,
clock time, etc. It would also be helpful to know how large the NVRAM is (in
bytes) and whether it is accessed as linear memory, or if there are some
intermediate address and data registers which must be manipulated to read and
write the NVRAM.
I assume that the information that I want to change is stored in this NVRAM
because it is available before the drive is online. I have a two-headed
NeXTdimension, and I have noticed that right after power-up, the graphical
icons used for network or disk boot are displayed either on the NeXTdimension
output or the MegaPixel output, depending upon which screen was most recently
chosen for the login panel in the Multiple Screen Layout Preferences. The
reason that this is important to me is because the ROM monitor uses this
setting to pick a screen for its window, and scrolling is incredibly slow on
the NeXTdimension output when using the ROM monitor. This tends to make me
want the MegaPixel as the login screen so that single-user operation during
backup procedures will not be slowed down by the inefficient scrolling. But
the full color features of NEXTSTEP are not realized when booting from the
MegaPixel, because that forces the Dock and all other programs to default to
the monochrome monitor instead of the color NeXTdimension. Selecting the
NeXTdimension as the login screen allows NEXTSTEP to look its best, but every
time I make a backup I have to deal with the slow scrolling.
I have devised an elaborate workaround, but I would prefer to have direct
control over this setting which is stored in NVRAM. For any of you who might
want to use the workaround, I have found that the Window Server always displays
the login panel at a fixed offset from the coordinate origin for the screen(s)
as set in the NetInfo database. The ROM monitor does not have access to
NetInfo, so it uses the NVRAM setting. I can trick the two systems into using
different monitors if I make changes in a particular order. Since the Multiple
Screen Layout Preferences code is currently my only way to write this NVRAM
setting, I first choose the MegaPixel for login and the reboot to force the
setting to be written out (restarting the Window Server does not seem to be
sufficient). At this point, the /localconfig/screens/MegaPixel/bounds has the
Display PostScript origin and
/localconfig/screens/NeXTdimension/bounds is set to locate the color monitor
relative to its physical position from the MegaPixel (usually). If I manually
change these NetInfo properties to place the NeXTdimension at the origin, and
flip the relative coordinates to keep the MegaPixel properly located (something
that the Multiple Screen Layout Preferences is usually in charge of computing,
based upon mouse input), then I can exit the Window Server and regain full
color NEXTSTEP operation.
This is a somewhat fragile workaround, because any time you touch the screen
settings through the normal NeXT utilities, the two settings are reset to match
each other, and I have to go through the extra reboot cycle to get them back to
the most efficient settings. A program which could independently make the
NVRAM setting would make this much easier.
In addition, I would need to know what sort of program would be necessary to
access this physical memory. Is it sufficient to run a program as root, make
some Mach system call to remove virtual mapping on a particular pointer or
memory range, and then read and write this NVRAM? Or is this a privilege
level reserved for the kernel and loadable kernel services. I hope that the
former is true, but I am willing to write whatever is necessary.
Once I have access to the NVRAM, it should be a simple to hack the location
in the NVRAM that is used for this particular setting by saving a copy of the
entire NVRAM both before and after a change which only affects this one value.
Of course, if someone already knows the offset, I would welcome the
information.
It would probably make sense to reply to me directly, since this information
is somewhat esoteric.

No--sender isn't a keyword, but a convention in how the Target/Action model
is implemented. Often you'll have an action such as:
- doStuff:sender
{
do_my_thing;
return self;
}
and then you'll call it (let's say in an object called "bezerkView") using
something like
[bezerkView doStuff:self];
So the calling object passes a pointer to itself to the called object, thus
allowing two-way communication.
Files produced by InterfaceBuilder's Unparse have this framework.

I keep getting an error when linking against a library. The error says that

its getting to be a pain.
Also, is there a way to specify the -posix flag to cc in the actual c source?
For a project I am working on some of the code requires the -posix argument
to cc and some does not leaving me running between a shell and Project

Neither of these are real problems just major annoyances. Any help would be
great.

The power saving features vary from somewhat from monitor to monitor. My

after it detects a BLACK screen. I use the BackSpace black screen saver and it
works fine.

Due to the success of several NeXTSTEP based mission critical systems, my
Chicago based clients are currently searching for experienced NeXT
professionals for new and existing projects in their top systems groups.
Candidates must possess a strong background in NeXTSTEP development,
Objective-C, EOF and/or Appkit/DBKit, coupled with good experience in
utilizing a RDBMS( Sybase/Informix/Oracle), and have successfully brought
a project no matter how big or small to a successful completion.
You will be responsible for developing a wide range of systems from
banking and finance to telecommunications and the entertainment industry.
These positions will be based in and around downtown Chicago, and are not
all with clients that are well known NeXT users.
As expected salary and benefits are excellent.

Date: 5 Dec 1995 09:57:01 GMT
Organization: University of Lausanne CH (Switzerland)
Message-ID: <4a151d$57n@cisun2000.unil.ch>
I'm trying to return NSDictionaries from my server either by reference or by
copying. I'm using EOF 1.1 and NS3.3. I have the example with EOF and
distributed objects, and I am using the FoundationExtentions which implement
the NXTransport protocol on NSArray and NSDictionary.
I have no problem getting the NSDictionary over the wire from the client to
the server. But when I try to return an NSDictionary (without any special
objects i.e. only NSStrings and NSDictioaries in it) from the server to the
client, the connection times out. When I converted the NSDictionary into an
NSString it seemed to work fine.
I have also tried changing the timeouts up to as long as infinity with no
help.
The dictionaries are the same size in each case, approx. 2k.
Thank you for any ideas, suggestions...

Just a little expansion on this. Usually, the sender is the IB object that
the connection was drawn from, like the text item or button. However if
you have a matrix of items (checkboxes, buttons...) and you draw the
connection from each different item in the matrix, the sender is the Matrix
not the Item.
The importance of the use of sender is that it is a standard for defining
those methods that the IB will be able to call. IB can only call methods
that take a single parameter, the "sender"

hello,
i've spent half a day already on a maddening problem with
tiff images dissapearing from a project bundle:
-- i have a project of type bundle, with several nib files
and a number of .tiff files included in the project under
"Images"
-- when viewing, under IB, the Images suitcase of the file
window, for all my nibs, I can see all my tiff files there OK
-- the problem starts when i build the project under PB:
-- when checking the resulting myBundle.bundle directory and
the .nib files underneath, using IB, i can no longer see
my .tiff files!!
BUT: 1) they are included under the myBundle.bundle
directory
2) they cannot be added to the Images suitcase of the
nibs' file windows (i get the message "image already exists"
3) when examining with the IB inspector the buttons
whose icons are tiff images, the names of the tiff files are
there, but they do not show!!
4) i compared, with "diff" all the unix files under the
nib directories, to see whether any differences exist within
the myBundle.bundle/*.lproj/*.nib/* files: no difference!
.. thanks for ANY cues.

The example
[stream deactivate];
[stream setParameter: NX_SoundStreamSamplingRate toInt: newRate];
[stream activate];
Clears all internal stream buffers but I don't want it! :-(
Any better ideas? Thanx for any resond, Gerald

I generally use the "sender" standard in my own code as well; I don't always

I have successfully compiled libscheme on NS Intel 3.3. With libscheme
you can interpret scheme code from within your own C or Objective-C
programs, which makes it a very nice extension language.
From the README:
libscheme is a C library implementing Scheme as described in the
Revised^4 Report on the Algorithmic Language Scheme. It is easily
integrated into a C program as a command interpreter or extension
langauge, and is easily extended in C with new primitive types,
primitve functions and syntax.

Authors' Guidelines
Object Currents presents the first significant hypermedia journal to provide
developers and managers of object-oriented systems with a full range of
articles covering the entire spectrum of object technology. Object Currents
articles are accompanied by several articles from SIGS' journals, but are set
apart by their "eye on the future" perspective. First priority is given to
new and advanced topics of real importance to the object community, including
applied research and development and new techniques and systems.
Advanced topics and techniques include but are not limited to delegation
languages, advanced programming techniques and idioms, advanced use of
methodologies, reflective meta-systems, new visual systems, GUI and
hypermedia, and new methods, processes, and metrics. New systems and
their use include but are not limited to programming languages, CASE and
meta-CASE, databases, operating systems, and distributed systems. All
articles should have emphasis on new technology and their use, but can
include the full range of traditional topics in object technology from
analysis to design and implementation, research and theory to practical
applications advice for real engineering and commercial environments, all
relevant object-oriented programming languages, including but not limited
to C++ and Smalltalk, and other relevant areas including interoperability
to X Windows and GUI.
Authors should capitalize on the unique multimedia and hypermedia
nature of Object Currents, as Object Currents is the first significant WWW
journal for software development. Hypermedia provides a unique
opportunity for the innovation of superior articles and information
systems technology.
All forms of hypermedia links and multimedia are strongly encouraged in

Articles (3 - 5 pages)
All submitted articles must satisfy some genuine need in the software
community with respect to object-oriented development, be highly
informative and lucid, and be appropriate to the intended Object Currents
audience. Articles containing new and advanced technology or method, with
an "eye on the future" perspective, and making best use of hypermedia will
receive highest priority.
Article sections should be numbered. Articles must have a brief one or two
paragraph abstract/summary. Recommended are sections on
introduction/background, goals and audience, unique contribution,
problems, benefits, issues and related works, conclusion, and
acknowledgements and references, as appropriate. Diagrams and examples,
including code fragments and complete programs, should be plentiful to
exemplify concepts.
Series (3-5 pages, 2-8 installments)
A series is a collection of articles offering the author an opportunity to
address a topic in great depth. The series may run from two to eight
installments. Series should be clearly partitioned into subtopics.
Column (2-3 pages)
Columns are designed to provide an ongoing discussion of a topic area,
offering the columnist an opportunity to cover a topic in great breadth over
an extended period of time, and to track changes and trends in the topic
area as the technology matures. Over time, the readers of a column should
gain an appreciation for the approach and style of the columnist and be
able to identify the people, companies, and products involved. Editorial
comments by both the author and readers are encouraged.
Newsgroup Dialog
The editor will take a thread or threads from the comp.object newsgroup
and provide commentary. Such threads may be started by the Editor and
may be related to the current issue.
Fun and Games
Puzzles to be picked up from the C++ Report and the net. Puzzles can
include obfuscated programming code, preferably from a well-known
language, or any other sort.
Questionnaire
A questionnaire will appear in each issue raising questions of importance
to the object community, typically concerning the issues raised by that
issue. The results from the last questionnaire will appear in the next issue
of Object Currents.
SIGS Bookshelf (2-3 pages)
Reviews of books, videos, and conferences. These should have the "eye on
the future" perspective of Object Currents. A review should describe the
purpose, content, and intended audience of the item and make critical
comments on its accuracy and success in fulfilling its purpose. If
appropriate, the author should comment on the suitability of the item for
educational purposes.
Movers & Shakers
Interview or profile of object industry VIPs. An interview or profile should
discuss the "movers" background, such as research interests, current line of
work and primary contributions, primary work today, object of interview or
profile, and conclusion. An "eye on the future" perspective should be
maintained, including a discussion on where the "movers" contribution
will bring the object community in the near future.
Code Watch
Source code will be provided at the SIGS site, possibly mirrored from
another. This code may come from SIGS journals or anywhere, such as on
the net.
Editorial Comments
Comments on the previous Object Currents issue, including other editorial
comments, provides a means of feedback and interaction for both author
and reader.
Potential topic areas are enumerated below; this list is not exhaustive and
creativity is encouraged. Topics should be drawn from new and advanced
areas of object technology. SIGS topics are very similar, but Object
Currents articles emphasize the latest and most advanced technology, how
it should be incorporated today, and where it is leading tomorrow.
Applications
Authors should discuss how advanced object technology should be used to
improve current practice. Successes and failures can provide valuable
feedback on future directions and what to follow and what to avoid. How
new or advanced techniques improve quality, productivity, or problem
solving should be reported. Learning curves, obstacles and their removal,
required support, metrics optimization, and other issues where
improvement is needed in the software industry today should be addressed.
Transitioning from old to new technology can be addressed.
Example Topic Areas:
- Advanced Applications
- Modern Systems support
- Visual programming, hypermedia, Java, VRML
- Advanced OO frameworks, patterns, APIs, Libraries
- Application portability, open systems, new standards
Hypermedia
The World Wide Web has been described as object-oriented. New approaches
to hypermedia, especially the World Wide Web, are desired. Java, VRML,
Python, and other new languages and systems are of interest. New and
innovative use of the Web and/or hypermedia by object-oriented applications.
Example Topic Areas:
- The object-oriented WWW
- Better approaches to hypermedia with object technology
- Innovative use of hypermedia and the WWW by object-oriented applications
- Innovative or novel use of new approaches, such as Java, Python, VRML.
- Exemplary use of graphics, animation, or video.
- New Standards
- New Tool Support
- OO VR, development, use
- Integration with the Web, e.g. OODB, Systems, interfacing
Idioms, Languages, Environments, and CASE
More powerful and expressive idioms and techniques in object-oriented
programming are desired. New languages and environments can be
discussed, including research languages. New paradigms in OO, such as
delegation, and new environments, such as metacase, are of importance
today. Perhaps examine issues of power, flexibility, orthogonality,
expressiveness, correctness, portability, availability, suitability, and
style with an emphasis on modern use.
Example Topic Areas:
- New constructs in OO
- Better approach or technology
- New CASE and why it should be used in real development
- New Idioms or advanced programming techniques to follow
- Reflective systems and extensibility
- Metasystems
- Advanced use of polymorphism
- Advanced uses of inheritance: multiple, dynamic, shared, etc.
- Advanced reuse - theory and practice:
- Efficiency/optimization vs. power expressiveness
- New Standards
Databases
New developments and advanced topics in OODBs can be addressed.
Where, when, and why a new technology is required. Reasons for
transition to and acceptance of object databases including advantages
(over older and/or other approaches) and new ideas should be presented.
Example Topic Areas:
- New OODB technology
- New and novel uses of OODBs, such as for business objects
- Distribution, concurrency, reliability, security - And WWW?
- Advanced Languages Interfacing
- Uses and Integration with other object systems - E.g. languages, CASE,
business objects
- New object query languages and use and 4GLs
- Schema evolution and its importance/relationship to OOD.
- Superiority of new OODB approaches over others
- New standards and ideas
Analysis And Design Methodology
New techniques in analysis and design are always being devised. Older
methods are evolving and fusing into newer methods. The need to utilize
the new methodologies and how to best achieve their acceptance is of real
importance today. Identifying future trends is of interest to readers.
Comparisons between the new methodologies and what they imply, or at
least why the new technique is superior.
Example Topic Areas:
- New and better methodologies and their use
- Best or creative uses of OOA/D, perhaps in new application domains, such
as business.
- Most relevant domains of use, strengths and weaknesses
- New techniques proven to be effective
- CASE/METACASE support
- Extensibility and reuse
- Use in process
- CMM/SPICE/Other approaches: standards, reviews, walkthroughs, JAD,
RAD, Spiral Model, and etc. Modern practice and experience.
- Improved cost drivers, moving effort upstream
- New fusion efforts
Process
Software engineering processes are a hot topic today. The SEI's CMM
level 1.0/2.0, ISO SPICE and the modern management practice of process
improvement are of great relevance to today's software development.
Discuss how object methodologies and technologies fit in with and better
support modern software engineering processes, such as Boehm's Spiral
Model of development.
Example Topic Areas:
- New and better development processes - how they relate to OO
- OO's basis in modern and flexible processes, especially in analysis and
design
- Experience with modern process and OO
- Handling the transition to modern from legacy processes, such as the
waterfall model
- Novel use of analysis models
- Metrics and process
- Process optimization
- Process and methodology, suitability of various methods to various processes
of development
- Process specialization and generalization - what should be tailored and what
should be standardized intra- and inter- organizationally.
- Standards - ISO/SPICE, SEI, etc.
Management - OD - Project Management - Testing
Modern management theory and its application to OO development. TQM, CMM
2.0, SPICE, Baldridge, Deming and their relevance in todays markets. Best
practices, world class standards, and productivity. Statistical control
and process improvement. How do these relate to object technology and
methodology? Modern learning theory and its application in education (at
all levels) and practice. How OO affects or improves project management,
planning and estimating, SCM, quality, and system evolution.
Example Topic Areas:
- TQM/CMM 2.0/SPICE/Baldridge/Deming applied to OO development.
- Improved metrics: e.g., reduced cycle time, time to market, ROI, quality
of life.
- Effects of improvement efforts, including OO.
- Introduction of new techniques and technologies, innovative approaches
- Grass roots efforts at quality (stealth quality and SE?)
- Instituting change with very modern technology and technique.
- Staffing for new OO technology development - e.g. Boehm's 5 principles
- Enterprise modeling and design, hypermodern techniques.
- Dealing with user needs and expectations, early analysis.
- New standards, Baldridge, ISO, etc.
Education and Training
How the new OO techniques are best taught and how training should be
provided is of real importance today. One Level 5 organization provides
45 days training to all developers before starting, is this best? What are
the alternatives? The need for improved education and training in both
academia and industry, especially with regards to real-world development,
is of importance. How should new OO techniques be taught or used in
initial development efforts?
Example Topic Areas:
- Application of new learning techniques to object education; such as
learning tools
- Teaching/learning object technology
- Experience reports
- Transitioning from programming to object-oriented analysis, design, and
programming
- Learning curves. How long does it take to reach proficiency, or various
levels of expertise at very modern techniques? Optimizing the learning
curve.

Hi there!
Anyone of you know how to make a window that was created using the PSwindow

I want to get keystrokes using the DPSGetEvent command, but all keyboard input
goes to another window on the screen (the key window, that is).
PS: I am not using the appkit. So makeKey... isn't possible!

I tried IB's Group in ScrollView function, and now have the following
problems:
1) It's not possible to ctl-drag connect my custom view up to anything.
(This can be worked around by connecting first and then grouping)
2), and more serious, my view (a subclass of MiscDragView) now is
pathologically unable to receive events (mouse entered, moved, etc).
Yes, I have implemented the responder methods (mouseEntered: etc...) ;-)
I've tried [window makeFirstResponder:self], [window addToEventMask:NX...]
and so on, to no effect.
Telling the superview (ClipView) to set the doc cursor works, but that's
all....
What extremely obvious thing have I overlooked? :-)

Hi All...
I've been trying to build some code using the tools provided with PDO PR2 for
Windows NT and have experienced a problem I hope you can help with.
In some source directories I have no problem performing a make. In others I
receive the following error:
$make
failed to spawn subshell [C://NextLibrary/Executables/sh] Invalid argument;
errno=22
make[1]: *** [build_tools] Error 2
make: *** [library] Error 2
$
I'm using the Bourne Shell delivered in the PR2 release and have verified that
sh is in the C:/NextLibrary/Executables directory. Since this is the same in
the directories that I'm able to "make" properly, I'm at a real loss as to why
I'm getting this problem.
Can anyone help me on this one?
Thanks a million in advance!
Sincerely,
Mark Ferguson

I am wondering where the adapter for Microsoft's SQL Server is in the EOF

They say they have one specifically for MS SQL, but I only have one
for Sybase and Oracle. Is there a package I havn't installed or
do I need to just use SYBASE which I have been using, but it
doesn't seem 100% right.

You should ask this to the guys/girls at NeXT. Besides the handfull
of alpha-testers outside of NeXT are they the only ones that can answer
your question. The rest of us has to wait until the PR1 in Q1.

Message-ID: <4a549f$peu@nntp.interaccess.com>
I've been trying to use a NXTableView from EOF to store information that the
user can edit directly through the table view. The NXEditableFormatter class is
supposedly responsible for the editing of a cells information. I want to be
able to control the information that is being put in the cell, like no blank
cells. NXEditableFormatter has three delegate methods that I want to use:
formatterWillChangeValueFor:at:sender:
formatterWillChangeValueFor:at:to:sender:
formatterDidChangeValueFor:at:to:sender:
Theoretically, these methods should allow me to make sure that the cells
information is the way I want it before it is actually saved.
However, I can't get any of these methods to be called. I setup the delegate
for each formmatter for each column in the table view, and checked it in gdb.
All the connections look fine, however, they just never get called. Maybe these
methods aren't called when I think they are, but that doesn't make sense. From
what I've read, they should be called once the user has entered information into
a cell and typed return.
Has anyone worked with this view enough to know how to get these methods to
work?

Need Help with EOF Server 1.1 on HP-UNIX.
Scenario:
We have installed PDO and EOF Server on HP-UNIX; Tto test
EOF Server, I generated a Project file using Project Builder
on a NextStep system running on Intel Machine; The Project was
generated in as Tool.
I have copied the code on to the HP-UNIX Machine and set the
CC as gcc and added the path variable to look for gcc which comes
with PDO, and EOF Server.
I also make use of the gcc-make (/NextDeveloper/bin/make) on HP-UNIX
while I make my project; and I get the following link error.
This same example compiles fine in NextStep by adding the
NeXT_p lib, but I don't have the same lib on HP NextDeveloper.

Because the object you are sending the 'endEditing' method to is of type
'id' (so you can hook it up in IB), and the compiler finds multiple
objects that have that method, it just picks one that it thinks you
mean. It is easy to fix. Just type cast the object when you use it.
Like so:
[(NXTableView *)myTableView endEditing];
Then it will know what object you mean, and the warning will go away.
This is a good way to do things anyway, so that the compiler can tell you
if you screw something up. But, then I'm the type that makes sure my
compiles have no warnings so that when one shows up, it catches my attention.
Good luck,

Message-ID: <4a65lu$kvr@ubszh.fh.zh.ubs.com>
I'm stucked with the following 3 problems :
1) Where does the InterfaceBuilder has his preferences saved ? I have
installed some Palettes (from the MiscKit) and one of them has screwed up
the prog. (it reports something like "NXStringReadOnly: does not respond to
- replaceWith" and then quits).
2) Is there an EASY way to give a subprocess access to a view in a main
window without confusing DPS ? So far, I tried the usual cthread stuff, but,
without creating an new view within the thread I was unable to write in an
already existing view.
3) Just for learning purposes I want to use the DBKit and the DBModeler but
I don't have a fullfledge Oracle or Sybase database system (.. for what
anyway ? I have a standalone pc). I tried mSQL (which seems to be a very
good prog) but there was no Adaptor around. Because I just started to
investigate the NeXT system a little bit more in detail, I'm not the guy
(yet) who is able to develop all the needed drivers or whatever one needs
for such stuff. Therefore I'm looking for some Freeware/Shareware or very
cheap commercial database (relational or object-oriented) packages which can
be used for building small applications (with corresponding Adaptor and so
on).
I very appreciate any help, which can lead me somehow through the jungle of
NeXTstep programming.

Stop.
The orst archive contains an updated midi driver and libs, but even these
appear to be for motorola only (using otool.app to check).
Am I missing something? Do these exist for Intel? Or has this library been
superceded in some way by something... ?
Thanks for any help (I know I could cut the MIDI part of csound out
altogether, but I would rather solve the problem).

well, i'm back, having found the answer finally...
so, for the benefit of other beginners:
- the images not LOCAL to a nib file within a
project of type bundle are not automatically accessible
from an application importing the bundle. I am using these
images as boutons' icons to get them without coding within
windows.
-- the solution: import (drop) these images within the Images
suitcase (I am under NS3.2) of a nib's file window and
choose "create LOCAL image" when asked by the "Deposit image"
alert panel.
- also to note: when viewing the images in a nib's file
window, you cannot immediately know whether an image is local
to the nib: you have to check the corresponding PB's images
suitcase - if it's not there, then it is local to the nib.

Hi all,
I have some friends who are writting a pin-ball game on NS. They came to me with a problem
and I can't seem to find the answer (although I can make some HACKS around their problem). The
problem is as follows:
- The movement of the flippers is controlled by the mouse. There is a nasty initial delay
in the key-repeat rate which is determined by Preferences.app. Is there a way to programmatically
set the repeat rate a certain responder wishes to use, or do you just have to fake continuous
actions by mucking around with - peekAndGetNextEvent.
Anyone who has tackled this problem before, I would appreciate some insight.
Thank you,

basically the I need to track the mouse and change the editing procdures

The standard Sybase EOF Adaptor shipped with EOF 1.1 workes with MS SQL Server 6.0. I didn't tested all functionality, but I hadn't any problems fetching, inserting, updating or deleting records.

Hi,
I am using a horizontal NXTableView in my App and configure it following
these steps:
. [nxTableView setRowHeadingVisible:YES]
. [nxTableView setColumnHeadingVisible:NO]
. and some addRow:withTitle:
The NXTableView looks right in the gui, but his behaviour remains like a
vertical NXTableView:
When i click on a cell, a row highlights not the column, and the tab key
shifts the selected cell horizontally not vertically.
Are there some workarounds to reverse his behaviour?
Thanks.

The sender is just an id that 'points' to the object that called it.
Example:
object A calls object B, and passes self as the parameter.
object B then has an id that references object A.
[objA callit:self];
-callit:sender
{
[sender updateScreen:... etc...];
return self;

Once you have an id that references the object that called it,
you can do a lot of useful things.
Example:
A button calls a method when it get pressed, and sends self as
the parameter. The method then can access the button through
the sender id, and tell the button to change the text on itself.
Just a top of the head example, I'm sure that you could come up with many
other ways of using the sender id.

Hi,
I just wanted to give you the chance to earn some money in a very easy
way.A friend of mine turned me on a company called Intercall
Marketing, which
offers a nice, uncomplicated way to get some more cash, just by
callingthem and advertising a bit.
The number of the company is
011-24-831-831
(if you're calling from the USA, in other countries it's (i think)
++248-313131).
The call has a fee of $1.50, so I think (hope) this isn't to expensive
for the possibility to get some more money.
Now I'll try to explain how it works:
After calling the number a recording gives you deatiled informationon
what to to next. After a brief description you will be asked to enter
a six digit account number of the person that gave you this number,
and this should be my account number.
It is -3 8 0 4 9 9- (this one is mine)
and then you can start to earn big money for nearly doing nothing. To
explain a little how it works, when you type in my account number, the
computer will give you you're own account number and a personal PIN
Number for your use only. Then it will record name and address for
future accounting needs, i.e. payments.
Here is where the money comes from:
For every call made to this number, intercall receives $1.50. 50 Cents
go to the account number you first typed in. But of course, now as
you've got you're own account, you'll want people to call and type in
your account number right away ! And I think, with the help of all the
networking systems around, it won't be a problem to reach many people.
Up to now its nothing special,
BUT IT GETS EVEN BETTER. You not only make 50 cents from the first
people who call using your number but also when they get people to
call using their number you get another 25 Cents from them, plus
another 25 cents from the people they get to call. So that means you
get paid 3 Levels deep, which could amount to some serious $$$.
An example:
If you get 100 people to call (by advertising in the net, or in the
local news papers), then you get 50$. If these people, let's say get
another 50 people to call, it's already $1,250. But the third Level
is the most important one(so you should perhaps hurry a bit), because
if these people get 25 people each, that means that you'll get exactly
$31,250 (just imagine, if every Level would get 100 people, you would
get $ 250.000). Some good cash for nearly doing nothing, isn't it ?
If you're wondering why Intercall does this, realize that they get 50
Cents for every call. 1st Level=$0.50, 2nd Level=$0.25, 3rd
Level=$0.25 => $1.00. Remember that they'll get $1.50 for each call,
so that leaves 50 cents per call.
I normally dont try this things out. But it's (IMHO) not possible to
loose much money, and just paying $1.50 for calling, and then perhaps
getting much more cash, it's not too bad ?
But now I stop trying to convince you. You have to decide if this
possibility of earning cash is worth $1.50. Thank you very much for
reading, i hope it didn'T bother you.

Date: 8 Dec 1995 16:57:10 GMT

Message-ID: <4a9qp6$r4f@hippo.shef.ac.uk>
I have asked the same question before, i.e., I have a matrix of action cell
class called "matrixCell" which cannot remove some of the unused icons from screen. I have implemented some of the suggestions given by many people
(thank you) and it still don't work, this time I wish to show the code, and hope that someone can spot my mistake.
/*
File : Controller.m --- inherit from "Object" class
Instant variable id window -- connect to the main window
id matrixCell -- connected to the matrixCell class, however
-- I did't use "group scrollview" to group
-- that matrix view.
int lastSelectedCol -- the selected column number before
-- user select the next one
*/
- appDidInit
{
......
lastSelectedCol = 0;
......
}
- renewMatrixCell
{
int cells;
if (autoSynchronize)
{
cells = lastSelectedCol + 1;
[matrixCell renewRows: 1 cols : cells];
[matrixCell sizeToCells];
[matrixCell selectCellAt: 0 :cells - 1];
[matrixcell update];
}
return self;
}
- setAutoSynchronize: (BOOL) flag
{
autoSynchronize = flag;
return self;
}
- iconSelected: sender // sender - from matrixCell class's mouseDown method
{
[self setAutoSynchronize: NO];
[window disableFlushWindow];
[matrixCell setAutodisplay: NO];
[self setLastColumn];
[self setAutoSynchronize: YES];
[self renewMatrixCell];
[[matrixCell setAutodisplay: YES] displayIfNeeded] ;
[[window reenableFlushWindow] flushWindow];
return self;
}
- setLastColumn
{
id iconCells = [[List alloc] init];
int i = ([matrixCell selectedCol]); // user newly selected column
while (i++ < lastSelectedCol)
[iconCells addObject: [matrixCell cellAt: 0 :i]];
lastSelectedCol = [matrixCell selectedCol];
i = [iconCells count];
while (i--)
[[iconCells objectAt: i] setDelegate: nil];
[iconCells free];
return self;
}
What my problem is, supposing we have 4 icons on the main window now, and the
4th icon is highlighted, if I clicks on the 2nd icon, I want
the 2nd icon to be highlighted and the 3rd and 4th icon to be removed from the
main window. Unfortunally, everytime when I do this, the 3rd and 4th icons
are still appear on the screen, however, if I "RESIZE" the main window, they
gone immediately and this proves that I have successfully remove 3rd & 4th
icon's delegate away, but for some reason, they are still there. I think
I did not "flush" the window properly, because "window" here is not the
instance variable "window" of matrixCell. I did try
[[matrixCell window] disableFlushWindow];
[[[matrixCell window] reenableFlushWindow] flushWindow];
and
[[[[matrixCell window] makeFirstResponder] reenableFlushWindow]
flushWindow];
but still cannot remove the 3rd and 4th icon.
Your help will be much appreciated. Thanks
Cheers,

The problem I am experiencing is that the Adapter does not recognize

I got NS 3.3 for my Pentium system about a week ago mainly so I
could get some basic experience in C programming in a UNIX
environment and I was also interested in doing some advanced 3D
graphic design (all of this without spending TOO much money). But,
I assumed that NeXTStep (like all the other UNIX OS's) came with a
basic C compiler like 'cc' on the R/S 6000. Am I just too new to
NeXTStep to FIND the C compiler (I'd feel REALLY stupid if this were
the case) or is it really true that the only way I can do C
programming on NeXTStep is to get NeXT's Developer Upgrade (and pay
$5000???)? I tried to download and use gcc v2.6 but I have to have
a C compiler in the first place to compile gcc before I use it,
right? HELP, I feel like I'm running around in circles! :-(

Has anyone else had reason to attempt to use "hideOtherApplications"
from the Workspace request protocol? I'm trying to use it, and it
flat out doesn't seem to work. I got as simple as a small window
with a button, the button sending a message to my controller object,
which consists of nothing other than one method. Looks like:
- hideOthers:sender
{
[[Application workspace] hideOtherApplications];
return self;
}
I build, run, and press the button, but nothing happens. I've
confirmed that I get the Workspace object (an
NXWorkspaceRequestProxy), and I send it the "hideOtherApplications"
message with no problems. (Void return value, so that doesn't
provide any clues.)
Any ideas? Can anyone confirm either that it truly is broken or that
I'm somehow overlooking something seriously obvious?
This is on black hardware running 3.3, and on white hardware running
3.2.

Has anyone successfully compiled the lib's? I'm using gcc2.7.2, and I am

What do you mean saying "subprocess"? But in general, AppKit is NOT thread safe and
it's a real pain (but possible) to focus the drawing operations from different

The base 'cc' compiler that some Unix systems used to ship with was
normally a deliberately crippled version that was only intended was use
when building a new kernel.

It's really true that the only way you can do C programming under NEXTSTEP
is to purchase NS/Developer.

Actually, you can even get some pre-compiled versions of the compiler from
various FTP sites, but just the compiler won't get you anywhere without the
header files and libraries (and documentation).

flame wars from .misc.
news:comp.sys.next.announce
Announcements of general interest to the NeXT community (new products,
FTP submissions, user group meetings, commercial announcements etc.)
This is a moderated newsgroup, meaning that you can't post to it
directly. Submissions should be e-mailed to next-announce@digifix.com
where the moderator (Scott Anguish) will screen them for suitability.

Messages posted to announce should NOT be posted or crossposted
to any other comp.sys.next groups.
news:comp.sys.next.bugs
A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used
NeXTs--that's what .marketplace is for.
news:comp.sys.next.marketplace
NeXT stuff for sale/wanted. Material posted here must not be
crossposted to any other c.s.n.* newsgroup, but may be crossposted to
misc.forsale.computers.workstation or appropriate regional newsgroups.
news:comp.sys.next.misc
For stuff that doesn't fit anywhere else. Anything you post here
by definition doesn't belong anywhere else in c.s.n.*--i.e. no
crossposting!!!
news:comp.sys.next.programmer
Questions and discussions of interest to NEXTSTEP programmers. This is
primarily a forum for advanced technical material.
Generic UNIX questions belong elsewhere (comp.unix.questions), although
specific questions about NeXT's implementation or porting issues are
appropriate here. Note that there are several other more "horizontal"
newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach,
comp.protocols.tcp-ip, etc.) that may also be of interest.
news:comp.sys.next.software
This is a place to talk about [third party] software products that run
on NEXTSTEP systems.
news:comp.sys.next.sysadmin
Stuff relating to NeXT system administration issues; in rare cases this
will spill over into .programmer or .software.
Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command

Subject: sound: listening with zero priority
Organization: OCSoftware
Hullo,
is there somebody who understand the SoundKit well? So as to
prepare my voice control system I'd need to record continually,
while allowing other tasks to play - even on PC's with the stupid
one-DMA cards. Help please!
I had prepared the receiving subproject using standard
NXRecordStream, but it locks the sound device so that nobody can
play anything (understandably, with only one DMA). IMHO there should
be a way to automatically interrupt the recording when _any_ task
wants to play, and resume it as soon as the playing is done. Is it?
In this particular case my software don't need even be informed
that the recording is temporarily suppressed; it would be perfecly
sufficient if simply the soundStream:didRecordData:size:forBuffer:
meesage (or its equivalent at other software level) is not sent
while somebody is playing.

I currently separate my objects as follows:
The main object encompasses all the behaviour of what I am trying to
model. This is where you have to be careful and ask yourself is anything
I put in here other than what the object essentially is? Try to be a
minimalist and leave in only what is required to get basic functionality
out of it.
Then I have a parallel object called the controller object. This is used
to set the attributes of my object and call it to do certain tasks, etc.
In most cases this object is created specifically for the main object but
can be used for several sub/super classes of that object. This object
knows how your main object works and knows the types of view objects that
will be used to access your main object. I also subclass this object in
parallel with my main object
The other end is a view object and this is what the user sees, and
interacts with. This is where the appkit classes focus on. Using
Nextstep you probably won't have to write any of your own custom view
objects. These objects, through the services of your control object, are
used to view your main object and also change it.
Note that in some cases objects will only sometimes need a controller and
view. Put yourself in the thinking that it won't need a controller or
view and create it with this assumption. Then add the other stuff as a
separate object as you need it. Your control object takes values from
your main object and updates the view object (as in the case of REVERT or
SHOW VALUES). Your control object can also take values from the view
object and update your main object (as in the case of OK or ACCEPT
VALUES). Keep this in mind and you will be on your way to creating
objects with model-view-control paradigm with fewer obstacles along the
way.
..Mike.

Message-ID: <4ahcmk$jb3@rznews.rrze.uni-erlangen.de>
I am using this program :
"Djgpp is a DOS port of gcc, it is hosted under DOS (actually under a DOS
extender) and produces executables that run under DOS (well, the extender
again). This is simply a "port" of djgpp that hosts it under NeXTSTEP
(m68k
or i386) and yet still produces executables that run under DOS."
I am using it to port relatively small c programs. My problem is that the
exe program crashes the PC when it returns to DOS. This happens with
different programs checked with purify on a Sun.
Has anyone similar problem and eventually a solution ?
Thanks,
Bruno

Yes to both questions. The low level interface is controlled by functions
like objc_addClass(), objc_getMetaClass(), and so forth.
However, it's easier to work at a higher level and dynamicly load bundles.
If you wish to add new classes to the runtime, and you should examine
Categories (or even class_poseAs() or [class1 poseAs:class2]; if you wish
to change the way certain classes behave.
If you wanted to go truly crazy, you could even have your program spit out
source code to soemwhere in /tmp or some such, fork() and run the compiler
on this dynamicly generated source code, and then dynamicly load in these
new classes.

Software development provides some of business's most lurid horror

double or triple their budgets are common. So are stories of projects
that were outrageously late and those that never work at all. There are
many views to this problem.
"The major problems of our work are not so much technological
as sociological in nature. Most managers are willing to
concede the idea that they've got more people worries than
technical worries. But they seldom manage that way."

their work holds no meaning to them... [They] stay on the

To the best of my knowledge there is no general publicly available
documentation of the interface. To write EnhanceMail I had to
reverse-engineer Mail.app (for which class-dump and gdb were
invaluable). If you want to write a bundle today it would probably be
easier to start from EnhanceMail rather than doing all the work from
scratch. In particular if you only want one small feature added, this
can often be done by adding just a few lines to EnhanceMail and I'd be
happy to include those in future releases of EnhanceMail.

Thank you for everyone who has help me on this issue. I have solved the

instead of sending
[window flushWindow]
Just a conceptual question, can anyone tell me what are the differences between
"display" and "flushWindow" method ? It seems like "flushWindow" method
does not cause those "dirty" views to redraw themselves, especially when those
views are made of a matrix of cells. Although I have solved the problem but
I am still a little bit confused. Thank you.

My idea. Pose a new Class YourNXPlayStream with a modified playData method.
This method checks if SoundKit is recording und stops this action. But how to
start it again? Hmm ..... difficult.

Subject: New i386 NEXTSTEP Sound solution needs Sound System Driver sources
Message-ID: <DJHvHJ.Mut@sounds.wa.com>
Organization: Sound Consulting, Bellevue, WA, USA
Date: Tue, 12 Dec 1995 22:22:31 GMT
I would like to write a NEXTSTEP driver for the Ensoniq Soundscape multimedia
card. I have just finished writing the Windows NT driver for Ensoniq which
supports all (five or so) revisions of their hardware and firmware. This
card has either an AD1848 or AD1845 CODEC, and is thus very similar to the
Microsoft Windows Sound System card - with the addition of MPU-401 MIDI and a
great deal of custom hardware. Gateway is shipping these cards in a probably
all of their new machines.
Since I understand that the Microsoft Sound System card is the best performer
for NEXTSTEP, and since that card is no longer in production, it seems to me
that the Ensoniq Soundscape could become very popular for NEXTSTEP users who
need a solid sound solution.
I would like to start with the Sound System Driver sources, merge any
additions necessary for MPU401 support, and then add Soundscape-specific
capabilities. There really is not any documentation of the Soundscape
hardware outside of Ensoniq, so I am the prime candidate for writing this
NEXTSTEP driver.
Can anyone tell me where to find the Sound System Driver sources for
NEXTSTEP's DriverKit? If anyone at NeXT is listening, I believe that this is
an important opportunity which would warrant releasing the sources, under
non-disclosure if need be. Of course, this supposes that they are not
already available. I will attempt to call NeXT this week, although I have no
idea who I should be talking to there.
The card has SoundBlaster emulation capabilities, but since the Ensoniq
engineers required the NT driver to work in native mode, I doubt that using
the NEXTSTEP SoundBlaster driver would perform very well (not to mention the
fact that the Soundscape would have to be set into SoundBlaster emulation
mode somehow).

I'm really lost on this. Here is my understanding. In fact, I have
build my own EOAssociations and a bunch of other gobbledeegook just
to get around this. Have I done all this work for naught?
1. We can't use IB to instantiate subclasses of EOController.
2. EOAssociations take over the target action paradigm, and cause
you all kinds of trouble when you attempt to intervene
(which I do, in fact).
3. For textfields, they also take over the text delegate role.
4. EOController delegate methods can tell you when a textfield
is edited, but not how the field is exited. Hence
we don't know when return was pressed (ie. when the
target's action is activated).
Please set me straight.

I am wondering if the problem is also due to strong typing or not. Would
it be possible to make a NeXTSTEP with a more dynamic language like e.g.,
Java, which has also strong typing ?

I can confirm that this method is completely non-functional.

Someone at Sun decided to pick the same magic number for Java's .class
files as our MAB files (some ex-NeXT folks worked on the early Java
implementation). I sent mail to the Java group at Sun a while back
regarding this as a potential conflict, but got no response.
Too late now.

Hello everybody,
Could you please email me your experience working with different
DBMS using EOF.
I'll summarize for the group or better put the summary on WWW.
Generally, I'm interested in the following information
How good does it handle large ( about 10GB and more ) data sets?
How easy is it integrated with EOF?
How good is the SQL support?
Where could I find adaptor for it and how much does it cost?
Any other information are greatly welcome.
I recall posts about mSQL recently, but I haven't archive them.
Could somebody repost them to me.
Thanks,

Absolutely. I use this approach everywhere. A class such as "Customer"
should, IMHO, be totally free of anything having to do with a GUI. Consider
this: I recently finished working on a Human Resources system, where
one of the central classes was (you guessed it) an Employee class. The
first thing I did was create an app for creating and editing employees,
using
EOF of course. But, I also needed to create a handful of daemons to perform
various processing nightly. The last thing in the world I want to do is
have references to interface stuff, since it has no meaning in this context,
and it would mean that I have to link against the appkit, etc (actually,
I still do, since the eoaccess library has appkit references in it (mumble,
groan) but that's beside the point).
Categories, I think, are such a nice solution. As Chuck mentioned, you can
add the category in the apps where you need it, and leave it out where you
don't. Incidentally, I use categories for separating all sorts of
functionality, not simply for separating GUI from non-GUI code. Any object
that has different, definable sets of behaviour in different contexts,
can be nicely broken down into categories. This also keeps your source
files
from being huge and jumbled, an added bonus.
Just my $0.02, of course!
Later,

Message-ID: <4an7iv$plj@opal.southwind.net>
I'm wanting to reltae the Postcript contex to a Unix pid.
Nextstep has the display postcript functions currentactiveapp and
setactiveapp
which provides sets the context number for and application.
The way I understand it each application gets a postscript context for
drawing (right wrong ?) It can fork of more drawwing contexts but all
contexts are owned by one appp otherwise the currentactiveapp would fail
with a fork context. (It doesn't seem to)
This leads to the propelm that a context is not and shouldn't be a unique
identifier for a app. No problem I have Unix pids for that.
If so I should be able to find the Unix pid's of all application that have
a current context and thus find out who's printing to the screen how many
windows etc from the window server.
The probelm I have is currentactiveapp/setactiveapp are the only poscript
operator I can find that returns the context assosiated with a app.
On the poscript side I have:
screenlist
array context screenlist subarray
Fills the array with the window numbers of all windows in the screen list
that are owned by the PostScript context specified by context. It returns
the subarray containing those window numbers, in order from front to back.
If array isn't large enough to hold them all, this operator will return
the frontmost windows that fit in the array.
If context is 0, all windows in the screen list are returned.
currentowner
window currentowner context
Returns a number identifying the PostScript context that currently owns
the specified window. By default, this is the PostScript context that
created the window.
From these two I get all current poscript contexes.
What I want is to do is find the application that owns a context and from
there since contex's arn't uniqe get the pid for the application.
For example a poscript operator
context ownerapp int string
Were ownerapp returns the pid and name of the app. In a system independent
way this would just return a string.
Is there such a beastie?
Or does anybody know of any way to get it that not the terrible hack I'm
contemplating? I don't want to do the obvious and given the context
setactiveapp and the get its pid. This will run through every application
making it active ugh.

Subject: Programmatically setting an NXSplitView??
Nextmail_Accepted: Certainly!!!
I am trying to institute an NXDefault in my app which will allow me
to bring up my window with the NXSplitView placed where the user
left it the last time they used the app.
I've figured out how to force the split view to a certain position
using "splitView:getMinY:maxY:ofSubviewAt:". What I can't figure
out is what message to send to the NXSplitView to make it invoke
that delegate message.
I have tried resetting its frame and its size but that didn't seem
to do the trick. It would appear that only the user dragging the
divider sends the message.
If any of you have solved this problem before, I would appreciate
any clues you can pass on.

There seems to be no support in the postscript language to call C

In fact I can't even faind a generic "sytem" type call.

The problem with Pswrap is that its not dynamic. You can not PSWrap

Also, does anyone know of a way to find the end of the paragraph that you

The splitView:getMinY:maxY:ofSubviewAt: will allow you to constrain the
positioning when a user drags the divider bar but is not useful for
establishing the initial position of the divider bar as you discovered.
I use the following code snippet to establish the initial split view
position.... assumes that splitView is the entire split view and upperView
and lowerView are the upper and lower views of the splitView respectively.
...
NXRect splitViewFrame, upperViewFrame, lowerViewFrame;
[upperView getFrame: &upperViewFrame];
[lowerView getFrame: &lowerViewFrame];
[splitView getFrame: &splitViewFrame];
upperViewFrame.size.height = DESIRED_SPLIT_VALUE;
lowerViewFrame.size.height =
splitViewFrame.size.height - upperViewFrame.size.height -
[splitView dividerHeight];
lowerViewFrame.origin.y =
upperViewFrame.size.height + [splitView dividerHeight];
[upperView setFrame: &upperViewFrame];
[lowerView setFrame: &lowerViewFrame];
[window display];
...
One other note about split view positioning is that if the splitview itself
scales when the window is resized you might have to implement the -
splitView:resizeSubviews: if you want better control over the final size of
the various views comprising the splitview after a resize. (i.e. default
behavior is to scale all views proportionately but what I desired for
example was for the lower view to shrink as much as possible before
beginning to change the size of the upper view when the window was made
smaller.)
Good luck.

Hi,
I am fairly new to NS programming (2 month or so) and just started to
enter the EO-world. Of course now I have to deal with the NSObject
hirarchy as opposed to the appkit/Object one that had been sufficient
up to now. My problem now is : How does one debug (with gdb) NSObjects ?
They don't have any instance variables besides 'isa', so how do I, for
example, find out what text is contained in a NSString object? Another
problem is, gdb doesn't seem to be able to step through List/NSArray
objects, is there a workaround for this ? I have heard of a 'printFor
Debugger:' method implemented by 'normal' Objects, which is changed to
'description' by NSObject. Can I access this one somehow ? Do I have to do
any setting up of the debugger (like changing 'print-object' so it calls
'description' instead of 'printForDebugger:'. Can gdb display the NSString
object 'description' hands back ? Should I add any categories to the
NSObject structure to facilitate debugging? Any help with this would be
appreciated, as I am doing my diploma work and need to use EO.

[... all providing thoughtful comments on why NeXT isn't as successful

Let me offer a slightly different >OPINION< on why NeXT isn't
the winner I had once thought it would be.
When the NeXT machine came out, it was, quite simply, an order
of magnitude more powerful than anything else on the market at
the time. It was easier to program, easier to use, cleaner,
prettier, faster, more robust, more flexible, and it could do
windows (smirk).
But you couldn't buy it.
Only college students and universities could buy it. And, to
boot, if Steve Jobs thought you were buying a "server configuration,"
he'd cancel your order, because according to the Book of Jobs,
NeXT machines weren't intended to be servers, but peers on a
network. This kind of thinking also promoted the boot-from-CD
philosophy that performance-crippled many of the machines.
When NeXT finally stooped to selling machines to the unwashed
masses, they chose Computerland as their sole supplier. You can
imagine how clueful the ComputerLand salespeople were WRT a
complex system (Mach kernel, UNIX capabilities, OO technologies,
all sorts of nifty (complex) software, etc. ad nauseum) like
that. They had a hard time figuring out how to sell PCs. They
put the NeXT machine in a corner and hid it, for fear that
someone might ask them a question about what it was.
In short, they made this neat thing, and then made it
impossible for anyone to buy it. They shut out the
people that could afford it. They killed their own product.
Damn shame, that. I still think it's the most powerful
box out there, bar none.
There are other reasons why NeXTStep hasn't succeeded as an
"open" operating system (it isn't open, only people like
IBM can afford to license it, etc.), but that can wait
for another day, and another discussion, if anyone's inclined.

Assuming you have NS/Developer installed:
ln -s /bin/cc /bin/gcc
...will let programs that try to autoconfigure themselves for gcc know that
the system 'cc' compiler is actually gcc.
If you don't have NS/Developer installed, getting gcc won't do anything

Dave,
The approach that we have taken with NXSplitView is to invoke the
resizeSubviews: method to initiate setting the NXSplitView's subviews to
particular positions.
If you implement the delegate method splitView:resizeSubviews:, that will
then be invoked for you to adjust the sizes of the subviews as appropriate.
If the documentation for these two methods is not enough, I can send you
example code.
Good luck,
Paul Heffernan, Product Development Manager.

Hi there,
Just an enqury of a possibility of an implementation.
Supposing I have a main window and a matrix of action cell. I would want
to implement sets of "dynamic" bottons. These set of buttons are dynamic
in the sense that, when I click on different action cell in the matrix,
different set of buttons will appear.
_______________________________________________________________________

This is how it works, when the user clicks on "icon 1", the first set of
buttons i.e., "Button 1", "Button 2" & "Button 3" will appear and from there
user can click on any of the button to perform some tasks. If users
clicks on "icon 2", another set of buttons says "Button 4", "Button 5" and
"Button 6" will appear and repalce the first set of buttons on the screen.
All the buttons have different funcitons to perform, depending on which icon
the user is currently selected.
I would want to know the possibility of such implementation, if you think
it is possible, and you know how to do it, can you please tell me, or even
better, if you know somewhere have similar examples, please kindly tell me.
Thanks in advance.

Date: 15 Dec 1995 19:39:33 GMT
Organization: my own
Message-ID: <4asitm$25b@gate.seicom.net>
Howdy,
I am trying to get elk 3.0 (a scheme implementation) running on NS. From the readme it
says that dynamic loading on NeXTSTEP 3.x is not reliable because rld_load sometimes
does not load the symbols. For what I have tried this seems to be true, however I found a
way to get it running. The following code fragment from rld_load.c shows how (The
UPPERCASE comments shows the differences to the original):
....
Disable_Interrupts;
/* Construct a stream for error logging: */
if ((err_stream = NXOpenFile (fileno (stderr), NX_WRITEONLY)) == 0)
Primitive_Error ("NXOpenFile failed");
retval = rld_load (err_stream, /* report error messages here */
&hdr, /* return header address here */
filenames, /* load this */
"/tmp/eload"); /* doesn't work if NULL?!
CHANGED FROM: "/dev/null" */
NXClose (err_stream);
if (retval != 1) Primitive_Error ("rld_load() failed");
/* ADDED TO GET SYMBOLS */
elfd=open("/tmp/eload",O_RDONLY,0);
fstat(elfd,&statbuf);
retval = map_fd(elfd,0,&memfile,TRUE, statbuf.st_size);
close(elfd);
/* END ADDED TO GET SYMBOLS, 'retval' not evaluated yet */
/* Grab the symbol table from the just-loaded file: */
if (The_Symbols) Free_Symbols (The_Symbols);
The_Symbols = Snarf_Symbols (memfile);
/* CHANGED FROM: The_Symbols = Snarf_Symbols (hdr); */
Call_Initializers (The_Symbols, 0, PR_CONSTRUCTOR);
Call_Initializers (The_Symbols, 0, PR_EXTENSION);
Enable_Interrupts;
Alloca_End;
...
In short I take the outfile from the rld_load call (it does not work if the parameter is NULL,
but 'man rld_load' tells me it does...?), map it into memory and feed this to the Mach-O
parser to get at the symbols. If I only use the 'hdr' as set by the rld_load call this does not
work reliable... For some .o files it will for others it won't.
Has anyone deeper knowledge why rld_load does not load the complete thing and if the
above workaround is a valid one (it seems to run all examples and tests ok!)? Or are there
better solutions for this (Remember this is no obj-c code and I have to use rld_load)?
What happens to a mapped file if the original is deleted or overwritten?

The above sounds just like an inspector...but w/o a popup, just using
buttons. The short answer is yes. The easiest route for you?
Probably using the tools in the MiscKit that aid in doing inspector
type work (which isn't all that hard to do even from scratch. The
Garfinkle (sp?) book has some very straight forward examples on this).

All pswrap is doing is constructing binary object sequences. That's just an

I'm trying to do exactly this with the Tools panel of my imagemapping

Last I heard they were going to be separate products, and indeed
products on separate time-lines. I remember that at some point
Jobs was saying OpenStep/WinNT would go beta in December, and that
there "was no reason to expect any problems" with having a Win95
version available sometime in 1996.

The original NeXT (the cube) was not faster than anything else
on the market at the time. To the user, it wasn't faster than
a mid-range Mac, never mind the most expensive Unix boxes that
were available back then.
The original wasn't fast enough for the people with deep
pockets, and it was too expensive for people who were
looking to buy PC's.
It wasn't really until the 68040-based Macs and NeXTSTEP 2.0
that NeXT was a really good buy compared to the competition.
By then, NeXT was selling to anyone interested in buying.

There was never a boot-from-CD philosophy. There was a magento-
optical philosophy which did hurt performance, even though it was
a neat idea in many ways. Just now the technology for MO drives
is getting to the point that NeXT needed to have it for their idea
to work.
If they could have had the Apex drive on the original NeXTstations,
for instance, it could have been a great matchup. They still would
have needed a floppy or a CD-ROM drive, of course!

The January 1989 issue of MACWORLD offers some data that would
indicate that the NeXT really was a good buy even in the 030 days.
Granted it was too expensive for most people looking to buy a PC, and
you couldn't get one if you weren't in academia, but according to the
price comparision given in the "What's Next?" article, it cost $18,375
(list) and $11,045 (consortium price) to bring a comparable Mac system
up to the level of the $6500 NeXT.

I would like to write a NEXTSTEP driver for the Ensoniq Soundscape multimedia
card. I have just finished writing the Windows NT driver for Ensoniq which
supports all (five or so) revisions of their hardware and firmware. This
card has either an AD1848 or AD1845 CODEC, and is thus very similar to the
Microsoft Windows Sound System card - with the addition of MPU-401 MIDI and a
great deal of custom hardware. Gateway is shipping these cards in a probably
all of their new machines.
Since I understand that the Microsoft Sound System card is the best performer
for NEXTSTEP, and since that card is no longer in production, it seems to me
that the Ensoniq Soundscape could become very popular for NEXTSTEP users who
need a solid sound solution.
I would like to start with the Sound System Driver sources, merge any
additions necessary for MPU401 support, and then add Soundscape-specific
capabilities. There really is not any documentation of the Soundscape
hardware outside of Ensoniq, so I am the prime candidate for writing this
NEXTSTEP driver.
Can anyone tell me where to find the Sound System Driver sources for
NEXTSTEP's DriverKit? If anyone at NeXT is listening, I believe that this is
an important opportunity which would warrant releasing the sources, under
non-disclosure if need be. Of course, this supposes that they are not
already available. I will attempt to call NeXT this week, although I have no
idea who I should be talking to there.
The card has SoundBlaster emulation capabilities, but since the Ensoniq
engineers required the NT driver to work in native mode, I doubt that using
the NEXTSTEP SoundBlaster driver would perform very well (not to mention the
fact that the Soundscape would have to be set into SoundBlaster emulation
mode somehow).

This is related to my poscrtipt question since RTFM failed me.
Its directed to Next but I think its good for anyone with public domain
programs and it may get rid of a lot of Usenet traffic esp form me :)
I wish they would put all there docs on the web. Hint Hint.
Another neat idea would be to give people the option of providing there
email adresses to otheres who hit certian doc pages. This gets rid of the
fluff : )
Thus I could search the web for Next's info on DPS find the best man pages
if they don't solve it publish my email adrees and maybe a short
explnation of my problem.
Also maybe a button that I can acces once I register that I can click from
unsolved to solved.
These link could have and expration date etc and a "me to" link for peole
with similar problems.
If somebody else comes a long that is RTFMing they can email me to see if
I solved it, remind me to change my question to solved etc.
This provides a dynamic connection for people working on similar problems.
If a problem is common say 50% of the people acces the page to solve the
same problem Next could link it in as a FAQ to the man page.
I think this would be a hell of a lot better demo for the power and
dynamics of webobjects than looking at stupid cars I can't afford : )

This comment seems inconsistent with what NeXT is saying on its Web site.
There NeXT states that OpenStep for Windows will support the development of
apps under both Windows 95 and NT. It also shows screen shots of IB running
under both Windows 95 and NT.
I don't doubt that OpenStep for Windows 95 and NT are 2 different
products and that the development of OpenStep for Windows NT is farther along
because NT has been available and stable much longer than 95, but if no
OpenStep for Windows 95 product is in the works, is the IB screen shot on
NeXT's Web site a fake?
We have potential customers who have chosen Windows 3.1 as their desktop
standard and plan to move to Windows 95 when it's stable. Moving to Windows
NT would be much more expensive for them because of its greater hardware
resource requirements and cost. We have assured them that our product will
be available as an OpenStep for Windows 95 app based on what NeXT has been
saying publicly.
If NeXT no longer has definite plans to produce OpenStep for Windows 95,
it needs to reflect this fact on its Web site. In addition, a public
announcement needs to be made so that we and others don't lose credibility
with potential customers.

According to NeXT, and Steve Jobs at Object World, OPENSTEP for NT will be
released Q1'96, and OPENSTEP for Win95 will be aimed for later in the year,
as it is currently in the works. They just have to do some GUI work to the
interface, as the Win95 interface is going to become the MS standard, even
on NT.
If for some reason, OS for Win95 is later than that, don't quote me. I am
not a representative of NeXT, and they are perfectly able to change their
itinerary without notifying me!! ]-) ]-)
( Though, if they should wish to keep me up to date with OS for Win95, I
will not get upset!! ]-) ]-) )

2. I am plotting multiple polygons using multiple calls to the method

I need to use compositing to achieve this effect, and what's the

Subject: DO nice trick
Organization: OCSoftware
Hi all the Distributed Objects users,
Are you aware that no method in multi client server is guaranted to
be processed mutually exclusive with any other method?
More specifically, should some method inside multi client server
communicate with a client by a proxy, _any_ other server method can
be called there:
-server_method_1 { ... }
-server_method_2:aProxy
{
...
[aProxy something]; // HERE might be called server_method_1!
...
}
In fact, this very strange behavior is indirectly documented: the
connection (used to communicate with the proxy) can serve other
client's DO request, which in turm might trigger any other server
method. Sorry to bore you if you had known this, but I guess almost
nobody understand till his/her program start crashing irreguralry
due to some critical section violation.
Here is a working example:
#import <appkit/appkit.h>
#import <remote/NXProxy.h>
#import <sys/types.h>
#define NAME "Nice trick, huh?!?"
@interface Proxy:Object @end
@implementation Proxy -(int)client {return getpid();} @end
@interface Server:Object
{
int mutex;
}
-(void)mutex:proxy;
@end
@implementation Server
-(void)mutex:proxy
{
int i;
mutex++;
// well, we don't use threads, so this method should
// be uninterruptible, shouldn't it? And the "mutex"
// part of the following printout should be always 1.
for (i=0;i<5;i++) {
printf("%d: mutex=%d (client %d)\n",i,mutex,[proxy
client]);
sleep(1);
}
mutex--;
}
@end
void main(void)
{
id main;
if ((main=[NXConnection connectToName:NAME])==NULL)
[[NXConnection registerRoot:[Server new]
withName:NAME] run];
else [main mutex:[Proxy new]];
}
simply make this program, run it for the first time as server and
then concurrently several times as clients - you'll get something
like
0: mutex=1 (client 9921)
1: mutex=1 (client 9921)
2: mutex=1 (client 9921)
0: mutex=3 (client 9923)
1: mutex=3 (client 9923)
2: mutex=3 (client 9923)
3: mutex=3 (client 9923)
4: mutex=3 (client 9923)
0: mutex=2 (client 9922)
1: mutex=2 (client 9922)
2: mutex=2 (client 9922)
3: mutex=2 (client 9922)
4: mutex=2 (client 9922)
3: mutex=1 (client 9921)
4: mutex=1 (client 9921)

It's more like Q2, last I heard. Probably just betas in Q1. They do
have a drop-dead date then, however, due to customer requirements.

A place to report verifiable bugs in NeXT-supplied software. Material
e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for
the net community find out about problems when they're discovered. This
newsgroup has a very poor signal/noise ratio--all too often bozos post
stuff here that really belongs someplace else. It rarely makes sense
to crosspost between this and other c.s.n.* newsgroups, but individual
reports may be germane to certain non-NeXT- specific groups as well.
news:comp.sys.next.hardware
Discussions about NeXT-label hardware and compatible peripherals,
and non-NeXT-produced hardware (e.g. Intel) that is compatible with
NEXTSTEP. In most cases, questions about Intel hardware are better
asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices
belong in comp.periphs.scsi. This isn't the place to buy or sell used

Related Newsgroups
==================
news:comp.soft-sys.nextstep
Like comp.sys.next.software and comp.sys.next.misc combined. Exists
because NeXT is a software-only company now, and comp.soft-sys is for
discussion of software systems with scope similar to NEXTSTEP.
news:comp.lang.objective-c
Technical talk about the Objective-C language. Implemetations discussed
include NeXT, Gnu, Stepstone, etc.
news:comp.object
Technical talk about OOP in general. Lots of C++ discussion, but NeXT
and Objective-C get quite a bit of attention. At times gets almost
philosophical about objects, but then again OOP allows one to be a
programmer/philosopher.

Welcome to the NeXTanswers information retrieval system!
This system allows you to request online technical documents, drivers, and
other software, which are then sent to you automatically. You can request
documents by fax or Internet electronic mail, read them on the world-wide
web, transfer them by anonymous ftp, or download them from the BBS.
NeXTanswers is an automated retrieval system. Requests sent to it are
answered electronically, and are not read or handled by a human being.
NeXTanswers does not answer your questions or forward your requests.
USING NEXTANSWERS BY E-MAIL
To use NeXTanswers by Internet e-mail, send requests to nextanswers@next.com.
Files are sent as NeXTmail attachments by default; you can request they be
sent as ASCII text files instead.
To request a file, include that file's ID number in the Subject line or the
body of the message. You can request several files in a single message.
You can also include commands in the Subject line or the body of the message.
These commands affect the way that files you request are sent:
ASCII causes the requested files to be sent as ASCII text
SPLIT splits large files into 95KB chunks, using the MIME
Message/Partial specification
REPLY-TO address sets the e-mail address NeXTanswers uses
These commands return information about the NeXTanswers system:
HELP returns this help file
INDEX returns the list of all available files
INDEX BY DATE returns the list of files, sorted newest to oldest
SEARCH keywords lists all files that contain all the keywords you list
(ignoring capitalization)
For example, a message with the following Subject line requests
three files:
Subject: 2101 2234 1109
A message with this body requests the same three files be
sent as ASCII text files:
2101 2234 1109 ascii
This message requests two lists of files, one for each search:
Subject:
SEARCH Dell SCSI
SEARCH NetInfo domain
NeXTanswers will reply to the address in your From: line. To use a different
address either set your Reply-To: line, or use the NeXTanswers command
REPLY-TO <your-address>
If you have any problem with the system or suggestions for improvement,
please send mail to nextanswers-request@next.com.

This is actually an essential feature in (P)DO which allows for
callbacks during synchronous method calls.
If you want to ensure that you don't get
interrupted from other clients, you have to use an
asynchronous protocol instead (which you probably want to
do if you get serious about using (P)DO anyway).
Our experience has been that it's a Very Good Idea (tm) to
do the majority of (P)DO calls asynchronous..
(avoiding interrupts as this as well as (especially) improving
throughput in the (P)DO system).

Well heres a partial answer I recived from Roger Peppe
<rog@ohm.york.ac.uk>
It seems there is a nicely undocumented function
DPSPrintf()
He used the example
DPSPrintf(DPSGetCurrentContext(), "postscript goes here...")
Now does Next document this function anywhere?
The only thing I could find in digital librarian was in
List.rtf - GeneralRef/03_Common/Classes
were it seems somebody at Next goofed and acutally mentioned it.
Maybe some simple things like does it perform a gsave grerestore
what is it's return values?
I'm pissed this little gem is so well hidden : (
It works the reverse of the way I asked my question but if I had asked
about calling arbitary postscript from C, which is what I really wanted
I felt I would get tons of uneeded info on PSWrap.
I figure other people might be intrested in the existance of this
undocumented function.
I wonder what other neat DPS functions Next has that it refuses to share?

(Sorry, I stumbled over this thread just today...)
Quite a lot.... not refusing to share but refusing to document right! Maybe they think mere
mortals should not dive too deep into this... but use the higher level methodes.
Now, can you say: 'To boldly go where only a few has gone before...'
BTW DPSPrintf is partly documented - just look in the header file dpsclient/dpsclient.h.
Others calls that could be of some value are DPSWriteData and DPSWritePostScript.
I use quite a lot of these functions in my PostScript debugger BeYAP.
A way to do some animations in a info view or similar using DPS functions is:
- drawSelf:(NXRect *)rects :(int)rectCount
{
% neglecting the rects above, remember this is only of educational value
PSgsave();
while (....postscript_data_available...) {
...read_a_single_line_of_data...
NX_DURING {
DPSPrintf(DPSGetCurrentContext()," %s ",the_single_line_of_data);
NXPing();
} NX_HANDLER {
fprintf(stderr,"Errors during display of Info Panel... (%s) !\n",
the_single_line_of_data);
} NX_ENDHANDLER
}
PSgrestore();
return self;
}
in a subclass of View. Every line is interpreted and drawn. You have the animation script
(in postscript) separate from the application, so you can change it quite easily.
BTW The real problem is not getting PS data into the interpreter but to get arbitary data
back to the application without waiting for it (say without a pswrap, but async)...

Subject: Re: text manipulation
Hello experts,
I'm doing some text manipulation using flex and bison ((better) GNU equivalents
of lex and yacc), but there are still occasions that I want to match things
from C code.
(For instance, I've matched a string, and then I want to detect substrings
according to a particular pattern. I could do that by first hackishly
commanding a sc_detect_format start condition in flex from bison, returning a
token indicating the precise format, and then I could direct the scanning of
the substrings from bison, using several more start conditions in flex. This
becomes a bit tedious after a while, however.)
Therefore my question: are there tools/libraries on the NEXTSTEP platform to
enrich the strcmp-and-such family of functions, allowing regular expressions,
but avoiding flex? E.g. (if object-oriented),
la=[LexicalAnalyser new];
[la useRESyntax:"lex"];
[la addRE:"re_isupper" meaning:"[A-Z]"];
[la addRE:"re_islower" meaning:"[a-z]"];
[la addRE:"re_isalpha" meaning:"{re_isupper}|{re_islower}"];
[la addRE:"re_isdigit" meaning:"[0-9]"];
[la addRE:"re_isxdigit" meaning:"{re_isdigit}|[A-F]|[a-f]"];
[la addRE:"re_isalnum" meaning:"{re_isdigit}|{re_isalpha}"];
[la addRE:"re_isspace" meaning:"[\\t\\n\\v\\f\\r\\ ]"];
[la addRE:"re_ispunct" meaning:"[\\ -\\/]|[\\:-\\@]|[\\[-\\`]|[\\{-\\~]"];
[la addRE:"re_isgraph" meaning:"[\\!-\\~]"];
[la addRE:"re_isprint" meaning:"\" \"|{re_isgraph}"];
[la addRE:"re_iscntrl" meaning:"[\\x00-\\x1f]|\\x7f"];
/*...*/
if([la check:str againstRE:"{re_isdigit}+\\\\. " matchLength:&length]){
/*...*/
}
More down-to-earth is welcome too. I specifically need to work with strings,
not files.

Hi,
Sorry for the cross post but I really need some help with this one. A few
years ago I bought an unopened version of Sybase Server (rel. ver. 4.1) for
NeXT hardware . I have only just installed it to do some work with EOF and
have found that bcp and bcptrans are missing and are not part of the package
reported by Install.app. Anyhow this is what is in my /usr/sybase/bin
directory, anyone know what's missing?:
buildmaster*
console*
dataserver*
isql*
probe*
syman*
upgrade4*
Also, if you do have the missing programs I would really appreciate a copy
of them. I don't think that would violate the copyright since I own a copy
of the server software and I'm quite sure bcp etc. are supposed to part of
it (according to NeXT answers).
Thanks for any help you can give.

Yes. It is documented in volume titled "Supplemental Documentation"

1990. It also is documented in "Programming the Display PostScript

Subject: DO nice trick
Organization: OCSoftware
Hi all the Distributed Objects users,
Are you aware that no method in multi client server is guaranted to
be processed mutually exclusive with any other method?
More specifically, should some method inside multi client server
communicate with a client by a proxy, _any_ other server method can
be called there:
-server_method_1 { ... }
-server_method_2:aProxy
{
...
[aProxy something]; // HERE might be called server_method_1!
...
}
In fact, this very strange behavior is indirectly documented: the
connection (used to communicate with the proxy) can serve other
client's DO request, which in turm might trigger any other server
method. Sorry to bore you if you had known this, but I guess almost
nobody understand till his/her program start crashing irreguralry
due to some critical section violation.
Here is a working example:
#import <appkit/appkit.h>
#import <remote/NXProxy.h>
#import <sys/types.h>
#define NAME "Nice trick, huh?!?"
@interface Proxy:Object @end
@implementation Proxy -(int)client {return getpid();} @end
@interface Server:Object
{
int mutex;
}
-(void)mutex:proxy;
@end
@implementation Server
-(void)mutex:proxy
{
int i;
mutex++;
// well, we don't use threads, so this method should
// be uninterruptible, shouldn't it? And the "mutex"
// part of the following printout should be always 1.
for (i=0;i<5;i++) {
printf("%d: mutex=%d (client %d)\n",i,mutex,[proxy
client]);
sleep(1);
}
mutex--;
}
@end
void main(void)
{
id main;
if ((main=[NXConnection connectToName:NAME])==NULL)
[[NXConnection registerRoot:[Server new]
withName:NAME] run];
else [main mutex:[Proxy new]];
}
simply make this program, run it for the first time as server and
then concurrently several times as clients - you'll get something
like
0: mutex=1 (client 9921)
1: mutex=1 (client 9921)
2: mutex=1 (client 9921)
0: mutex=3 (client 9923)
1: mutex=3 (client 9923)
2: mutex=3 (client 9923)
3: mutex=3 (client 9923)
4: mutex=3 (client 9923)
0: mutex=2 (client 9922)
1: mutex=2 (client 9922)
2: mutex=2 (client 9922)
3: mutex=2 (client 9922)
4: mutex=2 (client 9922)
3: mutex=1 (client 9921)

Hi,
I have experienced problems with Distributed Objects and
NextStep 3.3. We have upgraded a few machines to 3.3 lately
and suddenly applications using DOs started to break.
In order to find the problem, I built a small DO application
where the client connects to the server, sends a message
that gets printed on the server side and disconnects. The
server and client does not use EOF and Foundation Kit and
they are not being ran under the AppKit.
As said before, my server object has only one public method
which prints a message and returns an integer.
Now, if I run the client several times in a row, I get different
problems depending on the OS version the server and the client
is running.
Server Client Problem
3.2 3.2 No problem, works like a charm
3.2 3.3 After 128 connections, I get timeout on receiving (11013)
and the connection cannot be established. The server
is still available.
3.3 3.2 After 128 connections, the server cannot handle more
connections. The message "handleRequestOnPortal:
id <target> not available" appears on the server side
while the exception 11007(NX_objectNotAvailableException)
is raised on the client side.
3.3 3.3 Same problems as the third setup + problems of the second
setup.
Now the most interesting thing is by changing the server
method to be "oneway void" instead of returning an integer,
the previous problems described above disappear. But they
seem to reappear later, after establishing and freeing
1500 to 2000 connections on 3.3. No more messages can't
be sent and no errors are generated (the usual exception
is not even raised).
My tiny distributed application is compiled under 3.3,
and I get the same problems when it's compiled under 3.2.
I would like to know if anyone of you have had similar
problems. It looks like that connections are not being freed
and the maximum number of connections which is 128 is reached.
Also, there is a new feature under 3.3 which automatically
closes connections that are idle for more than 2.5 minutes.
So if run the client every 1 or 2 seconds, you will be
able to establish more than 128 connections.
Thanks,

It doesn't. This is the process in-memory size, but this does
count in all shared libraries mapped into the address space of
this process. While these libraries take up real memory (once),
they do already are in memory when you log in. So starting your
minimal up does not really cost you 1.5 MB extra memory.
Take /NextDeveloper/Apps/ProcessMonitor.app for a more detailed
view at your applications memory.

This is especially very dangerous when combining DO with autoreleasing
used in EOF. [NSAutoreleasePool release] on the server side must be called
only from the server main event loop. Otherwise, due to the DO behavior
mentioned above, [NSAutoreleasePool release] can be called inside any
server method, which communicates with the client.

At my non-profit, we got started with a small pilot grant from a
foundation, to digitize collections and make them available online. I had
been with Macintosh since 1984, but I knew from firsthand experience that
Mac sucked when it came to databases--big ones, I mean.
When I walked into a store in SF and seeing black hardware, I asked "what
about NeXT?" This guy got a very excited look on his face and said, "It
can do this, and this and this and that and this..."
Bottom line: a Mac Quadra with 1/2 gig drive and 16 megs of memory cost
$15,000 while a similarly outfitted NeXT cost only $10,500. And the NeXT
truly could "do this, and this and this and that and this..." We had to
buy used '030 Cubes to get the project off the ground and prove the
concept, but now we have 14 machines and work accomplished.
It has been worth it to be productive for the past four years. I would
have been shrill and would have been pulling my hair out all this time if
I was using some other platform.
I would have preferred a more bouyant outcome for the regular end-user,
but you pays your money and you takes your chance.

Date: 19 Dec 1995 09:23:02 GMT
Organization: Vienna University of Technology, Austria
Message-ID: <4b609m$lob@news.tuwien.ac.at>
Hello!
NeXTanswers 1810 states that the Soundblaster 16 Mixer supports CD-in,
line-in and microphone-in.
I couldn't test the other two inputs, but when I connect a source to the
external line-in, I can't hear anything (though recording works fine).
My questions are:
- Does the driver have a bug or is it simply that the mixer is initialized
to zero?
- If it is initialized to zero, is there any application to change the
mixer's
settings? (Sound preferences doesn't support the mixer).
- Or how can one program such an application? NXSound doesn't provide an
interface to the mixer.
It surely isn't a hardware problem, since it works fine with Windows95
(which even has a built-in front-end for the mixer).
Many thanks,
Willi

The book I have from Adobe is the Poscript Language Reference Manual for

suggests (I can't find the pages) That one look at the documentation
provided by the vendor. The additional documentation "The Display
Postscript Sytem Refernce Manual" is prominently mentioned. It's next on

will certainly call Adobe and find out about this book. I think I just got

Wow that's excellent documentation from Next. Easy to find since I din't
know the name of the function I was looking for just knew that there
should be one with the functionality I wanted.
Now does this function perform a /gsave /grestore on entry exit?
Seems that Nexts "documentation" doesn't mention that.

I will continue to stand by the fact that this function is not well
documented by Next I know its mentioned but considering its utility I
think it deserves far more than that. And in the private email I've
recieved Nobody else is happy about how Next's has documented it. Theres
nothing to suggest that a function like this is avialable in Next
documents one has to stumble upon it. In my case once someone told me the
name I found it. If you think this function is well documented than I
hope your not writing documentation for Next.
I will continue to make the accusation that Next's documentation has some
serious holes in it. And I think that many people have found that critical
or useful info is not present in Nexts documentation. I'm sure if we
started recording various "bugs" in the documentation and work arounds one
would be able to publish a book that would be a bestseller among Nextstep
Programmers.

Those that I've seen have only a concept overview. I was looking
for more in-depth. I understand the basic concept, I'm looking for subtleties.
e.g. I've seen some MVC implementations where the model broadcasts
specific change notices, like:
-attributeFooDidChange
-attributeBarGotBigger
-attributeGlobWasDeleted
I've seen other MVC implementations that only broadcast a generic change
notice and make the view figure out what.
-somethingAboutMeChangedAndYouHaveToFigureOutWhat
I've seen other MVC implementations that don't broadcast change notices
at all, only increment a statecode value (each change bumps the statecode),
and the view decides when to refresh itself by checking if the statecode
changed.
I've seen MVC's that offer to send custom messages when something happens
(e.g. target/action in NextStep), and MVC's that only send their own
notification messages (e.g. "-textDidChange").
I was hoping to find a book that would compare/contrast the stengths and
weaknesses of each of these, among other things.

Java is by no means a more "dynamic" language than Objective-C in the OO sense.
Java has no concept of selectors - that is, no - perform: functionality as
Objective-C and SmallTalk do. This makes it impossible to implement interface
builders and distributed or persistant objects without writing your own runtime.
Java and C++ share this lack of functionality.

Being in the software game for too long, I've learned to take
predicted release dates with a grain of salt. I would just be
terribly surprised to see OpenStep ship on anything other than
Solaris first. Anyone out there have any comments on this? Anyone
know what big customer is pushing the Windows release? Has NeXT
diverted much effort away from OpenStep/Solaris? (If you can't
tell, I am very eagerly awaiting OpenStep/Solaris)

Everyone I know who has switched to Windows 95 (not many, I admit) have
upgraded their hardware; more disk, more memory, one even upgraded their
CPU. Add in the extra overhead of running OpenStep on Windows 95, and
I have a hard time believing that your customers won't have to upgrade
their hardware.

Speaking of NeXT success stories, apparently IBM was recently running
a series of object technology seminars, centered on Smalltalk.
At one session (if not more) their success story was MCI's Friends
and Family. A NeXTStep project.
Naturally, they didn't bother to mention that.

****************************************************************
From the Supplemental Documentation volume which was part of the NeXT
Developer Library. (page 52)
void DPSPrintf(xtxt, fmt, [, arg ...]);
DPSContext ctxt;
char *fmt
sends string 'fmt' to 'ctxt' with the optional arguments converted,
formatted, and logically inserted into the string in a manner identical to the
Standard C Library routine printf. It is useful for sending formatted data or
a short PostScript language program to a context.

That's a specific example of a more general construct
called "Observer" in the fine book _Design Patterns_. As the
authors put it, you use it when you want a number of objects
to cooperate, but you don't want the design of the objects
to be tightly coupled.
They list the applicability as:
-When an abstraction has two aspects, one dependent on the other.
Encapsulating these aspects in separate objects lets you vary
and reuse them independently.
- When a change to one object requries changing others, and you don't
know how many objects need to be changed.
- When an object should be able to notify other objects without
making assumptions about who these objects are. In other words, you
don't want these objects tightly coupled.

Except for simple usage I think Windows 95 does/will require about
the same hardware investment as NT. Further, NT will acquire the
updated GUI sometime next year. NT should offer by far the best
chance of OPENSTEP working reasonably on a Microsoft OS platform.

Hi,
Sorry for the cross post but I really need some help with this one. A few
years ago I bought an unopened version of Sybase Server (rel. ver. 4.1) for
NeXT hardware . I have only just installed it to do some work with EOF and
have found that bcp and bcptrans are missing and are not part of the package
reported by Install.app. Anyhow this is what is in my /usr/sybase/bin
directory, anyone know what's missing?:
buildmaster*
console*
dataserver*
isql*
probe*
syman*
upgrade4*
Also, if you do have the missing programs I would really appreciate a copy
of them. I don't think that would violate the copyright since I own a copy
of the server software and I'm quite sure bcp etc. are supposed to part of
it (according to NeXT answers).
Thanks for any help you can give.

Give the right name of your MS SQL-Server in the DB-Login-Panel. Apart from that you need to add/create a line, describing your MS SQL-Server in the file /usr/sybase/interfaces. Like this:

If you link the MallocDebug library to your minimal app and
check, you'll see that the app probably allocates a total of
around 40k. Even this isn't totally accurate since it doesn't
take into account the impact the app has on system resources.
Try also using ProcessMonitor and AppInspector.
The ps -aux listing is an interpretation of the actual Mach
information. It appears to also factor in shared libraries
and memory that might be shared with other processes.

next don't seem to consider functions worth documenting.
classes are fine (they're `object oriented' and therefore fit in
with their intended direction)
unix had one man page for each related group of functions.
(finding the description for a particular function is merely
a matter of typing `man functionname'.)
next do not index their function definitions. it is quite laborious to
find the definition of a particular function under nextstep
because all functions for a particular section are documented in
the same file (17 files document approx. 650 functions!)
and it is impossible to look for the definition of a function
without finding all references to it as well.
this is quite apart from the fact that many functions have little
or no documentation at all. (a declaration in a header is _not_ adequate,
particularly when example NeXT code uses the function!)
oh that HeaderViewer was not so crippled with respect to documentation!
rog.
p.s. my views only, of course.

these lookups were global lookups, i.e. not restricted to the current

Software development provides some of business's most lurid horror
stories. Stories of projects only one-third finished but already costing
double or triple their budgets are common. So are stories of projects
that were outrageously late and those that never work at all. There are
many views to this problem.

as sociological in nature. Most managers are willing to
concede the idea that they've got more people worries than
technical worries. But they seldom manage that way."

Hi there,
I would like to ask question on iconbuilder about icon's white background,
not white christmas :)
Currently, I have happily used iconbuilder to build some 48x48 icons
(tiff file). However, when I use these icons in my matrix of action cell,
all icons have a square boundary and white background. I wish to build icons
that look like the folder icon in the file viewer or shelf. The folder icon
seems to have a transparent background, can I know how to do it, also if I do
not wish to do "alpha", is it possible to build icon with transparent background
?
Thank you very much and I wish everybody a merry christmas and happy new year.

I can't find it on my 3.3 devlopers CD ??
Ohh now it wasn't included and there's and obtuse reference on page 112 of
the General Reference?
I have had two books metioned too me now one by Adobe "Programming the
Display Postscript Sytem with Nextstep" and this one. Strangly enough I
ran across a reference to the book by Adobe it was in the corner of a mail
in post card in the back of the "red" book. Maybe Next could point out the
avialability of this book and the Supplemental Documentation? In a readily
aseccible place that most people would read.
Maybe with a line in the general documentation stating that these
functions are documented in the supplemental documentation?
I guess I was under the mistaken impression that Next had "all" of there
doc's on the devloper CD rom.
I am pissed about this, but mainly because I am completely alone in
programming Nextstep I have no other resouces but what is avialable
through the doc's and usenet. Thank you for pointing out this source of
info I will call Next and get the price/ISBN for this documentation.
I have written papers for the scientic journals and have spent quit a bit
of time searching for papers/references. Compare the documentation found
in the Journals with that avialable in computer science and I think you
will see why I think computer the computer docs are completly inadequate.
Hell the scietific reference is the equivlent of todays http and was
avialable in a good library say 200-5000 years ago. Cruzing the Journals
following links is not nearly as pleasent and experience it requires a
strong back and a bunch of nickels but a least you find what your looking
for : )
I don't want to argue this anymore I fell that the function was not
documented in a decent manner and there were no clues as to were I could
find out about it. (Remember I just had a gut feeling it must exist I did
not know it's name) I have found the answer to my question on the usnet
and the names of two intresting books I was unaware of.
Thank You

This question seems to be asked often enough...
This is what you can do to compile irc 2.8.2 on NS3.2:
Run configure, edit things in include/config.h, then make these changes
in include/defs.h:
#undef HAVE_SETSID
#define NEED_GETCWD 1
#undef HAVE_UNAME
#undef HAVE_DIRENT_H
#undef HAVE_MEMORY_H
#define HAVE_SYS_DIR_H 1
#undef USE_SIGACTION
#define BSDWAIT 1
#define HAVE_SYS_WAIT_H 1
also, add this line to defs.h:
#define WSTOPSIG(s) (s).w_stopsig
in the Makefile, make these changes: (get rid of all posix stuff)
CFLAGS = -O2 -fomit-frame-pointer
LIBS = -ltermcap
[I'm not sure if -fomit-frame-pointer will give you that extra register,
but it can't hurt. :) ]

Hi Chih Nam(?)
The only thing you can do is (as far as I know) USING alpha.
I never heared of a transparent color without alpha.

A very small success story:
Eight weeks ago, we opened an indoor rock-climbing centre
in London.
In five months of VERY part-time work, despite
being totally new to Next, I was able to knock up the
systems I needed (with invaluable help from Paul Lynch -
thanks). We're only tracking users' details so far, and
I'm sure my coding is atrocious, but the development
environment is a joy to work with.
We have about ten employees. One or two have used PC
applications, most are totally new. We are open seven
days a week until late, so it is kind of 'mission critical'.
Since opening, I have had just two phone calls at home with
problems. In both cases someone had switched off (and
rebooted) the server, and I told them how to restart the
database. Not one network problem. Not one General
Protection Fault.
We had some hiccups configuring the first couple of
machines, but then P&L Systems brought us a fresh one,
plugged it in, and It Just Worked.
My staff (really new to computers) all understand file
systems, networks and email thanks to the wonderful User
Interface.
When the people on reception want to run off another 200
registration forms, they can do it. When the printer in
the office is out of paper, it tells them. Never a hitch.
Lots of customers have come in and said 'Wow! Next!' and
seriously lost interest in climbing...
It was also cheaper than doing it with Windows....
Count your blessings. This is the best platform in the
world.
Merry Christmas.

Michael, I wouldn't feel bad about not being able to find this
documentation. I think Chuck Fleming is showing his longevity as a
NeXT developer -- the "Supplemental Documentation" is the last volume
of the "NeXT Developer's Library" from around 2.0 days, I think (the
date on my copy is 12/90 !).
That set of documentation became obsolete when the "new" (3.0) books
were published by Addison Wesley in November 1992. I doubt that NeXT
will sell you a copy now.
BTW, the "Supplemental Documentation" is just a collection of
reprints of various documents from Adobe, plus a mangled RTF spec
from Microsoft. It contains two page 52's (and about ten page 10's)
since each section is numbered separately.
Cheers,
Doug

Hi folks,
I encountered the following problem concerning the use of
categories within InterfaceBuilder:
There are several cases to consider:
1) Category for a custom class myclass inheriting from Object:
This works fine. I can drag any header file which contains
a category interface and the method will show up for myclass.
2) Category for a NeXT class inheriting from Object:
This does not work properly. The method does NOT show up in
the classes view for the class.
WORKAROUND:
Before dragging the category header file into InterfaceBuilder,
define it as follows:
@interface Application:Responder (Test)
- test: sender;
@end
then remove ":Responder" (This is not valid ObjectiveC).
NOTE: Sometimes the other action methods defined in the class
disapear.
3) Category for a custom class myclass inheriting from NSObject:
This is the same as 2).
4) Category for a NeXT class inheriting from NSObject:
This is the same as 2) but the NOTE seems to always hold in this
case.
Valid for Release 3.3 (v460)
Is there any proper workaround for the cases 2) - 4)???
Is this a known problem?
Am I making something wrong?
Thanks and a Happy New Year.

You can use IconBuilder to create (partly) transparent icons. The easiest
way is to make the transparent-to-be area some "strange" color, let's say
red. Then check the Format that you have alpha enabled (I'm not having
my NeXT at hand, so the names are a bit roughly).
Then in the color-panel, select white, 0% opaque = 100% transparent and
deselect the draw-in-overlay (???) button. Then use the fill function
to replace the red area with the transaparent white. Save the icon and
do Update-Viewer in the file-viewer, else the old icon remains used.
Success, couple of years ago I too had a big fight with this topic.

Is not the total number of pages (among other things) kept in the
accompanying .ctl file in /usr/spool/NeXTFaxes/<fax-name>/<user>/read ?
If the doc was received or converted into a 'true' fax corresponding to
Next's FaxReader.app, the control file should be present.

As Donald McGregor mentioned, the Design Patterns book is a good place to
start.
Though even the very general observer pattern has drawbacks as far as
maintenance goes.
(its hard to see the subtle dependencies between objects)
Another place you might start looking is in the extensive faqs for
comp.object
There is a lot of information in that enormous faq.

For those of you who remember Cassandra, I've got a somewhat newer
version available. The source has been changed a bit to get rid
of a lot of compile-time warnings, and I've fixed a few minor
bugs. I also removed it's screen-saver feature, because I've
always thought that Backspace did a better job and the Cassandra
screen-saver support never quite worked right anyway.
It is compiled quad-fat now, too. It probably requires that
you're running NeXTSTEP 3.0 or better.
I haven't done all that much to the source (although I did get
all the latest source, which isn't true of most source-archives
of it that I've found on the FTP sites), and what I've done is
not all that pretty. However, it seems to work fine for me,
running on m68k and Intel hardware over the past few months.
Consider it alpha software, seeing that I'm sure I haven't tested
all of it's features. I don't make any promises of future support,
although I wouldn't mind getting email of any problems you find in
it. I am also releasing the source that I've got, so you can fix
things if you're annoyed about something that I'm not getting to.
For now it's only available at:
ftp://eclipse.its.rpi.edu/NeXT/apps/Cassandra_f/
which is a folder that has four single-architecture binaries, as
well as a quad-fat version. The source for it is also there, in
a separate archive.
Merry christmas.

Subject: Developing for NEXTSTEP vs OPENSTEP---a critical business decision
Message-ID: <1995Dec27.234416.4569@heinz.com>
Sender: usenet@heinz.com
Organization: F. HEINZ Consultora
Date: Wed, 27 Dec 1995 23:44:16 GMT
With the impending release of OPENSTEP/Mach (aka NEXTSTEP
4.0) and of the OPENSTEP-compliant version of Solaris (I
keep forgetting the version number), we independent software
developers face a rather difficult decision, with very
little hard data on which to base it. Eventually, we will
all be talking OPENSTEP, but what should we be doing right
now?
The technical point is the following: on one hand, NEXTSTEP
4.0 will run NEXTSTEP 3.3 applications (at least NeXT
promised us it would), but of course it won't work the other
way around. On the other hand, NEXTSTEP 3.3 applications
will neither run nor _compile_ under OPENSTEP/Solaris
(NEXTSTEP 4.0 apps will run under OPENSTEP/Solaris, but it
requires a recompile). Now suppose you have, or are in the
process of creating an app, should you stick with NEXTSTEP
3.3 for the time being, or just jump to the OPENSTEP
bandwagon?
These are the available options:
1) You keep maintaining your code under 3.3 for the time being.
ADVANTAGES
- You are independent of NeXT and/or SunSoft meeting or
missing any deadlines
- You cover the whole NEXTSTEP 3.x and 4.x market
DISADVANTAGES
- You keep adding lines of NEXTSTEP to your code base, which
will have to be ported to OPENSTEP sooner or later. This
means that the more you do now, the more you will need to
do later.
- You fail to cover the OPENSTEP/Solaris market!
2) You move to OPENSTEP as soon as possible, and forget
about NEXTSTEP 3.x
ADVANTAGES
- Minimum porting effort. It will still take you some manpower
to do, but the sooner you do it, the less it will take.
- You cover the NEXTSTEP 4.x and OPENSTEP/Solaris markets
- You are all of a sudden serving a market other than
pure-NEXTSTEP
DISADVANTAGES
- You fail to serve all current NEXTSTEP users that won't
upgrade to 4.0 (I hear there are even people who still use
NEXTSTEP 2.1, and are happy at that)
- You may meet your deadlines, but will NeXT and SunSoft do
the same? You won't be able to ship _anything_ until at least
one of them actually releases the corresponding system software
- OPENSTEP is not shipping. We know it's there, we know it's cool,
but as long as it's not shipping, it's vapor. And developing
for vapor is dangerous
POTENTIAL DISADVANTAGE
- since the nib file format is not (repeat, _not_) part of the
OPENSTEP spec, there is no guarantee that nibs created under
OPENSTEP/Mach will be compatible with OPENSTEP/Solaris, or the
other way around. Of course, it is not altogether out of the
question either, but I have been unable to get an authoritative
answer on this issue. NEXTSTEP has other undocumented areas
(such as the NXTypedStream format) that may present similar
problems.
3) You move your code to OPENSTEP, but still maintain a
NEXTSTEP 3.3 branch
ADVANTAGES
- You cover the whole market
DISADVANTAGES
- Costly and cumbersome. Merging bug fixes and enhancements must
be done entirely by hand, and is probably even impossible---the
result being that you must multiply all your development efforts
by two. Keeping versions in sync becomes a nightmare for everyone
involved.
4) You give up programming altogether, and start a career as a tattoo
artist :-)
I for one think that alternative 3 above is at or beyond
the brink of being impracticable. Keeping two different code
bases for the same app means basically having two apps, to
care for, no matter how similar they may seem to the user.
It's true that only the development effort must be
duplicated (user docs, marketing, etc. may remain common to
both versions), but it still is too big a burden for the
typical NEXTSTEP ISV.
Alternative 2 is tempting. Programming for NEXTSTEP always
was fun, except for the bits of C drudgery that still
remained, and in OPENSTEP most of those have been removed.
OPENSTEP is technically superior to NEXTSTEP, there's no
doubt about it, but the most compelling advantage of going
OPENSTEP to serve a market other than the one dominated by
NeXT. Don't get me wrong, I don't want to get rid of NeXT,
they do really great stuff, but I do think they need serious
competition on their own field.
The really troubling aspect of alternative 2 is leaving out
all those who don't upgrade to 4.0. Maybe it's just my
naturally good disposition, but I don't expect neither NeXT
nor SunSoft to significantly slip the release dates.
However, there's no way of telling how much of the installed
base will stay with 3.x, and while this market may not be
huge, at least it exists. The OPENSTEP market, however
promising it may be, has still to be born.
I'm still wavering. Where are _you_ putting your money?

Just think about what NeXT themselves have had to do:
- They have literally millions of lines of code to convert to OpenStep
- They have had to port it in a very short time scale
- They have produced tools to make the porting as painless as possible
- They have said that they will be making these tools available to all
developers
This means that you will get porting tools that have been tested on
millions of lines of code. I would say that given this situation, it is
best to continue developing under 3.3 (possibly with some use of the new
foundation classes if your customers have access to the libraries), and do
the conversion when openstep arrives. NeXT have said that the tools will
do most of the work for you, but there are one or two things you have to
do manually. Apparently they are flagged for you, so it's pretty easy.
Does anyone at NeXT want to give us more details?

NeXT appears to have done a VERY thorough job producing automated code
conversion scripts that will do most of the NS-to-OpenStep (OS) code
conversion. Andrew Stone, Stone Design, has produced a nice guide that
chronicles his experiences with the OS 4.0 PR1 conversion process with an
extensive problem/solution section.
But neither NeXT nor Andrew dwell much on nib conversion which is a major
concern for me because our app has over 500 nibs containing many custom
objects including about 10,000 commercial palette objects. These custom
objects are all Objects now, but will be converted to NSObjects by IB 4.0, I
presume. Apparently, the IB API has changed so that IBPalette, IBInspector,
etc. will need to be converted and the palette rebuilt before it will load in
IB 4.0. Does this mean that we will need 3 versions of every palette we use?
- the current version that can be loaded by the current IB
- a version with the IB API converted, but still containing Objects so
existing nibs can be loaded
- a version with Objects converted to NSObjects.
Before any nib conversion can proceed, all nib objects will need to exist
in Object and NSObject versions, I presume. This could be a significant
coordination problem, especially for nibs that contain commercial objects,
especially if the original vendor has vanished and source isn't available :-(
I'd appreciate any comments about how you envision the nib conversion
process to proceed.

I have been working on a syntax highlighter for NEXT for a couple of weeks
now. It is very, very alpha right now. I am hoping to develope it along
the lines of CodeWright or WinEdit, etc. I don't know how much interest
there is in making it public, let me know if anyone is interested.
I know Emacs.app supports color, but a lightweight editor is what I hope to
achieve, without the bloat of such a large system.

Evidently, there is a group in MCI using and pushing Smalltalk, just as
there is a group betting on NEXTSTEP. So its possible that both NeXT and
IBM/Smalltalk can claim some fame from MCI's Friends and Family program.

Maybe you can do it from the shell:
----
#! /bin/sh
where='someDirectory'
ls -t | tail -10 | sed -e 's#[@/*]$##' -e "s#.*#mv & $where#" | sh
----
#! /bin/csh
set where='someDirectory'
ls -t | tail -10 | sed -e 's#[@/*]$##' -e "s#.*#mv & $where#" | sh
----
Hope that helps,
Stephan

I'm not very sure if I understand your problem, but I did something
similar in one of my own apps. Basically, I have a matrix of two
columns and variable number of rows. When the matrix is (re-)built
from an internal list, that list invokes the following method:
- fillMatrix
{
int i, n;
VocabEntry *item;
Matrix *matrix = [controller vocabMatrix];
[matrix setAutodisplay: NO];
// finish editing
[[[matrix window] firstResponder] resignFirstResponder];
[matrix clearSelectedCell];
[matrix renewRows: 0 cols: 2];
for( i = 0, n = [self count]; i < n; i++ )
{
item = [self objectAt: i];
[item appendToMatrix: matrix]; // which calls [matrix addRow];
} // for i
[[[matrix sizeToCells] setAutodisplay: YES] update];
return self;
} // fillMatrix:
The only significant difference between your code and mine is that you
invoke [matrixCell update] (in renewMatrixCell) _before_
[matrixCell setAutodisplay: YES] (in iconSelected:).
Hope that helps,
Stephan

Hi,
Have you experienced problems using distributed objects
under 3.2 and/or 3.3 or porting your applications from
3.2 to 3.3 that makes use of DOs?
If so, please let me know. I have experienced a few
problems with them lately and I'd like to know if I'm
the only having problems. They are essentially related
to the new feature in NS 3.3 where connections are closed
if they are idle for more than 2.5 minutes. I have also
some workarounds.
Thanks,

Subject: Re: text manipulation
Hello,
I received answers from "Erik M. Buck" <embuck@cca.rockwell.com> and Art Isbell
<aisbell@cubicsol.com> (thanks!).
Erik suggested any free regular expression library, in particular regex from
the university of Toronto, Canada. ``It is also available in several packages
on ftp.cs.orst.edu. (See the CVS sources there. It is used in many many
things, comes with ansi-C source, etc.)'' I didn't check this out, yet.
Art suggested the MiscKit's MiscString. Well, I've got an extra disk now, so I
went ahead and built it (version 1.6.2). The source shows that this is derived
from (or inspired by) the Toronto sources and from GNU. There are some
problems, however (briefly, and only the tough ones):
- no regex syntax documentation,
- no reliable longest-match matching.
Furthermore, keeping a string in one contiguous block of memory does not bode
well for the performance of search-and-replace operations on little stringies
of a quarter meg or so (I could be mistaken).
So I'm not entirely happy. (Ask me for details if you want them.)
But I really need something to split up a string into parts according to a
regular expression the (s)ed way (with \( and \) matching by \1, \2 etc.). This
is something that (f)lex does not do in a straightforward way (one needs to
hack around with / and several start conditions to make several passes, at
least, that is how I did it once). MiscString's -grep:before:middle:after:
methods are not smart enough. Can the Toronto regex do this?
And of course, I need it last week. :-)
Thanks,

Hi,
Someone earlier asked for a color-caple editor to highlight
keywords. Some followups suggested emacs. How do I highlight
keywords in Emacs 4.1 in NS for c, obj c , or scheme? Help
appreciated.
Thanks.
