bug in gdb lisp interface, or line numbering, or where? 25 years

Emmanuel Michon

Hi, I don't know who should be held responsible for the following bug (and if it's the right place to discuss about that) but: transform the line ends of the file given at the end into dos style ^M^J (I have to edit maintain compile and debug dos style source code). I'm using xemacs 21.2 beta 26 with mule enabled so that I can edit such files: the modeline shows ISO8:T. This file can be compiled with gcc-2.95 (older gcc's will not accept the \^M^J as a macro continuation). When you try to debug it with Meta-gdb the highlighted line is just not the good one (the line shift is the number of macro continuations). One more question: which variable should I tweak to change the color of this highlighting? Thanks a lot badlinenumbering.c ----------------------------------- #define MULTILINEMACRO doing \ absolutely \ nothing \ but \ confusing \ line \ numbering int main() { int x=0; int y=0; x=2; y=2; exit(0); } ---------------------------------------------------- -- Emmanuel Michon Ingénieur en développement logiciel REALmagic France Mobile: 0662834836 GPGkeyID: 8782772B

Note that some libc implementations also have a user-callable doprnt() function used by some unclean programs. Olivier might have thought on that one when he questioned its Mule integrity.

Use consistently the syntax #ifdef FEATURE, not #if FEATURE. 25 years

Stephen J. Turnbull

What's wrong with #if defined(FEATURE)? In the stuff I'm doing to encapsulate UTF-2000, I have a lot of #if defined(UTF2000) /* handle UTF-8 bufbytes and UCS-4 emchars */ #elif defined(MULE) /* handle leading byte representation */ #else /* --wthout-mule case */ #endif I'm not terribly happy with it, but it's the most readable idiom I've come up with. I use #ifdef for two-way branches; that helps to visually distinguish the multibranch case.

Hey... I like that idea. We could call it 'XEmacs＠Home' and say that we are harnessing your CPU power to find the biggest geeks in the world, who happen to be hiding behind beautifully rendered XEmacs screens. :) -bp

gtk status update.... 25 years

William M. Perry

I got tired of writing spec documents and started hacking some code for the really basic integration, and I've got a (tty-only right now) XEmacs that is using the Gtk / Gdk event loop to drive it. I didn't trust it quite enough to write this email message, but it does appear to work. There is something weird with the QUIT macro stuff, but... baby steps. :) -Bill P.

When I decided to switch to customize many months ago, I tried to convert everything at that time to customize. If more things have customize interfaces now, then I haven't made that change yet. I also haven't migrated all of my hooks to customize yet. Ray

But this is supposed to be for apps that are not in a buffer. Adding all the layout managers and things to widget would be kind of... icky. :) And not readily doable in text mode. Although if someone ever wrote a text version of this, I'd have to buy them lots of beer (and probably sedatives). -bp

You can't, customize only handles a subset of the things you would want to customize. Symbol properties and specifiers aren't handled (except though kludges) nor are something as basic ot an editor as key bindings. And of course, a developer will want to add new functionality, which is outside the scope of what customize _should_ do.
