However, 21.2 happens to be quite stable, so xemacs-beta regulars should not hesitate to try it out.

I've seen this sort of thing also. C-c C-c, and it hangs for a long time, flashing the gc cursor now and again.

Shell trouble - third post (was Shell trouble - second post, please read) 25 years, 4 months

Rodney Stromlund

Surely someone somewhere has had this problem. I am on a HP-UX 10.20 PA2.0. I have tried switching my stty settings to just about everything possible and I always have the same problem. I have not gotten a single email on this. Please just email me and tell me to shut up! Please read on : ** Previous post ** When I enter shell mode (I'm using ksh) if I start a program that has lots of output, I can't break it or move my cursor around until the program ends. Its almost like xemacs is waiting for the shell to take a breath before it will interrupt it. ie. If I pull a Homer and do "tar x" instead of a "tar t", I can press ^C^C and the screen freezes and I won't see anything until the find command finishes. But, when the screen finally refreshes, the find command was allowed to run to completion. Depending on the tarball, this could be a very bad thing! Then the ^C^C goes thru and I see a two command lines. That's just a little too late! This is happens with the latest release xemacs (21.1) and all betas I've used. This never happened on 20.4. Or: If I do a "tar t" and I want to start scrolling thru the output before the command finishes; as soon as I press a key the output freezes until the find finishes. And (say I pressed page up) the page up takes place from the bottom of the output and not where I actually pressed the key. This problem isn't there in telnet or rsh. It is there in rlogin and shell. If this is a FAQ or documented somewhere, just let me know. Otherwise HELP!!!!!!!!!!!!!!!! Thx in advance, ================================ Rodney Stromlund Southwest Airlines Co.

Here is the patch for it to work with itimers. It could probably be coded better (e.g. using the RESTART feature of itimers), but this should do for starters. The feature could probably be improved (more about that later), but it's quite nice even as it is. --- isearch-mode.el.orig Wed Jul 28 04:15:59 1999 +++ isearch-mode.el Wed Jul 28 04:16:03 1999 ＠＠ -1677,8 +1677,6 ＠＠ ;;; - the variable `isearch-invalid-regexp' is expected to be true ;;; iff `isearch-string' is an invalid regexp. -(require 'timer) - (defgroup isearch-lazy-highlight nil "Lazy highlighting feature for incremental search." :prefix "isearch-lazy-highlight-" ＠＠ -1731,7 +1729,7 ＠＠ (isearch-lazy-highlight-remove-extents)) (if isearch-lazy-highlight-timer (progn - (cancel-timer isearch-lazy-highlight-timer) + (delete-itimer isearch-lazy-highlight-timer) (setq isearch-lazy-highlight-timer nil)))) (defun isearch-lazy-highlight-remove-extents () ＠＠ -1759,8 +1757,10 ＠＠ isearch-lazy-highlight-last-string isearch-string isearch-lazy-highlight-wrapped nil) (setq isearch-lazy-highlight-timer - (run-with-idle-timer isearch-lazy-highlight-initial-delay nil - 'isearch-lazy-highlight-update))))) + (start-itimer "Lazy highlight" + 'isearch-lazy-highlight-update + isearch-lazy-highlight-initial-delay + nil t))))) (defun isearch-lazy-highlight-search () "Search ahead for the next or previous match, for lazy highlighting. ＠＠ -1805,8 +1805,10 ＠＠ (setq isearch-lazy-highlight-extents (cons ext isearch-lazy-highlight-extents)) (setq isearch-lazy-highlight-timer - (run-at-time isearch-lazy-highlight-interval nil - 'isearch-lazy-highlight-update)) + (start-itimer "Lazy highlight" + 'isearch-lazy-highlight-update + isearch-lazy-highlight-interval + nil t)) (if isearch-forward (setq isearch-lazy-highlight-end (point)) (setq isearch-lazy-highlight-start (point)))) ＠＠ -1815,8 +1817,10 ＠＠ ;; let's try wrapping around the end of the buffer (setq isearch-lazy-highlight-wrapped t) (setq isearch-lazy-highlight-timer - (run-at-time isearch-lazy-highlight-interval nil - 'isearch-lazy-highlight-update)) + (start-itimer "Lazy highlight" + 'isearch-lazy-highlight-update + isearch-lazy-highlight-interval + nil t)) (if isearch-forward (setq isearch-lazy-highlight-end (point-min)) (setq isearch-lazy-highlight-start (point-max))))))))))

Maybe we should just write somewhere that we have nothing against unified interface graphics libraries, but until one gets written that doesn't suck we roll our own.

Speaking of isearch-mode.el... 25 years, 4 months

Charles Hines

Since there seems to be an interest in isearch-mode.el right now, I'll ask a question I asked a long time ago - anybody know why using history with isearch is broken? For example, try this: run xemacs -q clear scratch buffer with C-_ enter 'a b c a b c a b c <RET>' isearch for a from beginning of buffer (M-< C-s a) stop isearch, then isearch for b (M-< C-s b) stop isearch, then isearch for c (M-< C-s c) stop isearch, then isearch for c again, using M-p to recall it, search for it twice, second time it starts looking for b instead of c (M-< C-s M-p M-p M-p C-s C-s) I've tried a couple of times (half-heartedly, I admit) to debug it, but haven't had much success other than it looks like the search-ring and search-ring-yank-pointer get out of sync at some point... The vanilla Emacs 20.4 isearch.el doesn't suffer from this, I noted, but they were enough different that it didn't really help me figure it out. Anyone have any ideas? Chuck -- Charles K.
