Including "vc-fossil.el" in vc? 5 years, 7 months

Hauke Fath

Hi, I nave been banging a bit on vc-fossil.el from <http://chiselapp.com/user/venks/repository/emacs-fossil/doc/tip/doc/index...>, and got it to work with Xemacses "slightly-older vc. Provided there is interest: What would be the procedure to include the fuke with the XEmacs vc?

is speed a concern? 5 years, 10 months

Julian Bradfield

Another possibly silly question arising from perusal of the great Mule merge... Is speed (or small linear factors in memory) ever actually a concern nowadays? The whole deal of supporting multiple internal buffer formats seems to be justified by speed for multi-lingual processing, and there are various tricky things scattered around the rest of the code to improve speed. The last time I can remember being disturbed by XEmacs' slowness was sometime in the mid 90s when I was running Lucid Emacs 19 on a 68040. (The days when a full compile was a go-out-for-long-dinner job rather than a you-may-just-have-time-to-make-coffee job.) On the other hand, I don't do extensive non-English processing. Do people find XEmacs noticeably slow in any normal usage pattern? -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336. _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta

Xft dpi font scaling 6 years, 9 months

René Rebe

Hi there, since years I use xemacs-beta, currently 21.5.34: https://t2sde.org/packages/xemacs-beta Except the lack of updates I am quite happy with that setup, however one details drives me increasingly crazy. Namely HiDPI font scaling when I switch between old displays and newer, 4k+ HiDPI, 192++ dpi screens. I have this font selection in my .xemacs/init.el (set-face-font 'default "Source Code Pro-13") ; or -22 for HiDPI Ideally I want this -13 to be pt, so that I do not have to edit the file each time I switch my desk or continue coding on the road. Googling around suggest others alternative forms which either do not work in xemacs-beta, or do not prove the situation. I tried to read the lisp files, but could not find anything that would help me there either. Is there anything "pt" like so that a 13pt would result in say 13 pixels on a low resolution display, and 26 (or whatever) pixels on a HiDPI screen with the X server dpi set accordingly? PS: Surprisingly the Xemacs menus and such sale automatically, just not this most important, main edit buffer, ..?

Building on GTK2 and GTK3 work with warnings but without problems for me. Please give details if it doesn’t work for you. I have undone Jeff’s change to config.h.in, and now WORS_BIGENDIAN is available again.

gdk_events_pending vs. gdk_event_peek 6 years, 10 months

Stephen J. Turnbull

Hi, I did a little spelunking with negative results. 0. Installed current macports sources for gtk3 (includes gdk3) and glib2. 1. There's nothing obvious in the implementation of gdk_events_pending, which first looks at event queues, I think, then goes and examines the "events pending" flag on each open display. If there's a bug, since peek doesn't find any events, I guess it's because somehow that flag doesn't get cleared even though the queue is drained, but I didn't feel like going after that yet. 2. There are no bugs on GNOME.org that look like this. Ditto trac.macports.org. 3. GNU Emacs doesn't use the toolkit event loop at all, but rather invokes event dispatch itself at the glib level. 4. glib also basically just checks "events pending" flags. 5. Thank god for grep. GNU keeps all of its events and command loops in "keyboard.c", and its handling of window system events in "xgselect.c", exactly where you'd expect to find them. <sigh/> I'll push on #1 later, and if that doesn't get anywhere I'll file a bug on GNOME.org.

GTK3 event loop broken on Mac OS X 6 years, 10 months

Stephen J. Turnbull

Jeff Sparkes, Aidan: If you're listening, I'd appreciate an ACK even if you have nothing to say. (Otherwise I'll eventually spam you personally ....) All, On Mac OS X "High Sierra" I'm having trouble with the recently committed GTK3 port (thanks Jeff and Aidan!) Lots of things are less than copacetic, but the first problem I ran into is an infloop if I even mouseover the toolbar. Turns out that gdk_events_pending can return non-zero even when gdk_event_peek returns NULL. So I wrote the attached patch to use the latter to test for no more events. This isn't great, but it seems to work. I think I got the GdkEvent cleanup right, but I suppose it's possible this leaks GdkEvents, so be warned. Steve

We could disable the charsets-in-region tests on the Unicode builds. Or have a defined order we expect depending on the current language environment; but to be honest, with unicode-internal, the output of charsets-in-region isn’t something the user is going to care about, I would lean more towards the former. > Footnotes: > [1] By the way, why does the Unicode build have a 2^30 repertoire? > ISO 10646 has a 2^31 repertoire IIRC (maybe 2^32?), but Unicode only > has 2^21 (precisely, 2^20+2^16). Ben’s choice. We do need more than 2^21, for our invalid sequence characters, but we certainly don’t need the full 2^30. -- ‘As I sat looking up at the Guinness ad, I could never figure out / How your man stayed up on the surfboard after forty pints of stout’ (C.

Test of all characters 6 years, 11 months

Stephen J. Turnbull

Hi, I got tired of having "make check" stall on mule-tests. Something I don't understand is going on, because Skip-Test-Unless is failing the char-code-limit condition, but doing the test anyway. The only thing I can think of is that Skip-Test-Unless is a macro but for some reason evaluates its condition anyway, which is a bug, but I'm not sure whether it's in XEmacs or in Skip-Test-Unless. Currently I'm dealing with it with the attached patch. If nobody has an idea about the underlying bug, I'll apply it in January. -- Associate Professor Division of Policy and Planning Science http://turnbull/sk.tsukuba.ac.jp/ Faculty of Systems and Information Email: turnbull(a)sk.tsukuba.ac.jp University of Tsukuba Tel: 029-853-5175 Tennodai 1-1-1, Tsukuba 305-8573 JAPAN

GTK 1 support has been removed from the trunk. 6 years, 11 months

Aidan Kehoe

I’ve just merged Jeff Sparkes’ GTK-2-and-greater branch into the trunk code, and imported the branch wholesale into the trunk. I intended to develop for GTK-2-with-pango by default from here on in, though of course I will support X11. I will be keeping an eye on the buildbot and will trigger a package rebuild in the next few days to see what provokes, but please get in touch if that provokes any issues. -- ‘As I sat looking up at the Guinness ad, I could never figure out / How your man stayed up on the surfboard after forty pints of stout’ (C.
