My favorite was Football/Golf -- sink your putt and race to the tee before you get tackled ... :-)

patch very preliminary support for /dev/pts/ 25 years, 4 months

Neal D. Becker

Here is a very quick patch that seems to work to support the new /dev/pts on linux glibc2.1. Obviously, better integration is needed. I suppose HAVE_GETPT needs to be added to autoconf. retrieving revision 1.11.2.5 diff -u -r1.11.2.5 process-unix.c --- process-unix.c 1998/12/29 10:54:27 1.11.2.5 +++ process-unix.c 1999/07/26 02:39:07 ＠＠ -216,6 +216,23 ＠＠ int fd; int c; +#ifdef LINUX +#define HAVE_GETPT +#endif + +#ifdef HAVE_GETPT +#define PTY_ITERATION +#define PTY_OPEN \ + { \ + int e; \ + fd = getpt(); \ + if (fd < 0) return fd; \ + if ((e = grantpt (fd)) < 0) return e; \ + if ((e = unlockpt (fd)) < 0) return e; \ + } +#define PTY_TTY_NAME_SPRINTF ptsname_r (fd, pty_name, sizeof (pty_name)); +#endif + #ifdef PTY_ITERATION PTY_ITERATION #else ＠＠ -265,7 +282,7 ＠＠ if (access (pty_name, 6) != 0) { close (fd); -#if !defined(IRIS) && !defined(__sgi) +#if !defined(IRIS) && !defined(__sgi) && !defined (HAVE_GETPT) continue; #else return -1;

Shouldn't Japanese be treated the > same as anything else? It's not the same thing. Under normal settings, Japanese characters display twice as wide as Latin characters. This means that using a computation like (- (point) (point-at-bol)) to determine indentation is broken.

Re: pgnus commandeers emacs to check mail 25 years, 4 months

Kyle Jones <kyle_jones(a)wonderworks.com> writes: [threads in emacs] > :) There is still the question for which I still have not heard > a good answer--- Why do this? As this discussion came from the ding list, I take the natural example. Emacs lock up for a long time when Gnus enters a huge folder. If there were support at the language level to start a truly asynchronous thread Gnus could build the summary buffer in background and present it to the user when it's finished. Using callbacks in the "asynchronous" process filters a'la M-x man as has been suggested won't buy us nothing -- the elisp interpreter is still synchronous. I also agree with the opinion that adding thread support at the language level is easier than making applications take advantage of threads. But that's a poor excuse for not implementing threads at the language level. > I agree that we could save some memory with threading vs. multiple > processes, but memory is much cheaper than man hours. We'd have to > overhaul the Lisp system and all the applications to make them > mt-safe, and all without funding? I can't imagine it happening. Neither do I. The only chance I see this happening is a project re-targeting Emacs under Guile or some other language that already have thread support. I think thread support in itself has to little momentum to gather enough interest.

vc-revert-buffer1 sacrifices fontification preserving minor modes 25 years, 4 months

Adrian Aichner

Both for RCS and CVS I use vc.el to perform version-control from within source buffers directly. Whenever I RCS-checkin or CVS-commit a file using C-x v v (vc-next-action) I loose fontification of that buffer. This also happens for C-x v u (vc-revert-buffer) I have (emacs-version) "XEmacs 21.1 (patch 4) \"Arches\" [Lucid] (i386-pc-win32) of Thu Jul 08 1999 on ZJ75T" and vc 1.18 Version Control for Free systems. I tracked this down to a specific argument `vc-revert-buffer1' supplies in its call to `revert-buffer'. It is true that it preserves minor modes (like footnote-mode) that way, but fontification is lost, although the modeline still says font-lock-mode is on. Only newly entered text is fontified. I tried calling (revert-buffer arg no-confirm nil) instead and this restores the fontification but looses the minor mode. To me this still seems the better alternative. --------------------------------- What is the correct fix for this? --------------------------------- Thanks, Adrian (defun vc-revert-buffer1 (&optional arg no-confirm) ;; Revert buffer, try to keep point and mark where user expects them in spite ;; of changes because of expanded version-control key words. ;; This is quite important since otherwise typeahead won't work as expected. (interactive "P") (widen) (let ((context (vc-buffer-context))) ;; t means don't call normal-mode; that's to preserve various minor modes. (revert-buffer arg no-confirm t) (vc-restore-buffer-context context))) -- NON DISPERDERE IL VETRO NELL'AMBIENTE
