explicit ghostty support in termsdesc.c

[dankamongmen]

we'll probably want an entry for ghostty by @mitchellh et al. let's get the latest built with the latest zig (i'm trying to package zig for debian right now, see https://lists.debian.org/debian-devel/2025/01/msg00098.html) and see what manner of thing we have here.

[dankamongmen]

hope you're not on fire, @mitchellh

[mitchellh]

Thanks. My family is presently safe. A lot of friends are impacted though and it’s just overall a tragedy.

Regarding this issue, let me know if there’s any help you need from me to smooth the process. Or if there’s anything extremely stupid I did I should correct, it’s still early innings and can get that in without burdening society with mistakes.

[dankamongmen]

from everything i've seen ghostty has moved immediately to the front of the line. once i've got it packaged in debian, i'll be using it more often (kitty remains my mainline for the time being, with foot on wayland, but i'm rarely in wayland). glad to hear you're not in danger. i hope 340 main street is likewise safe; i ate several delicious sandwiches there back in 2015, and later got unexpectedly laid at the Gjelina. LA >> SF forever

hack on!

[dankamongmen]

alright, after code updates pulled into ghostty this morning, i finally have a working one!

a very nice initial performance on notcurses-info. looks like we're detecting most stuff, wonderful. let's check whether it's doing quadrants/sextants/octants itself, or relying on the font...

[dankamongmen]

Box.zig suggests quadrants and sextants from a quick visual inspection. doesn't look like we have octants yet.

[dankamongmen]

we're generating some unimplemented OSCs, some ignoring CSI 22/23 with extra parameters, and a few other things, probably all fine but let's investigate them:

[dankamongmen]

looks like ghostty prefers TERM=xterm-ghostty

[dankamongmen]

good response to XTVERSION: ghostty 1.0.2-main+5cb2fa6f

[dankamongmen]

yeah sexblitter and quadblitter in keller both look great, plot looks great throughout notcurses-demo. whiteout looks perfect. some bleed on the right of mojibake. some weird underbleed in xray. some strange color interaction in zoo -- look at the right minibox (the one with the empty checkboxen). overall a bit slower than i'd like, but nothing unacceptable in peacetime. notcurses-demo output on 97x57 geometry with 11x24px cells on a 1368x1067 canvas:

[dankamongmen]

note that we're properly using kitty protocol, as indicated in the notcurses-info output

[dankamongmen]

either way, we're done here for now. welcome to the family ghostty!

[dankamongmen]

@mitchellh 's code looks pretty clean; if you're not planning on adding font-independent octants (see Unicode 16) in the immediate future, i might take a stab at doing so. holla at your boy!

We plan on it but not sure if anyone is working on it right now. Pretty easy to add via src/font/sprite. We even generate a bitmap for unit tests to detect pixel changes so you can't fuck up anything else (or, positively verify your new stuff is good).

awesome, i'll try to get this done this week. btw i just uploaded zig0.13 to debian's NEW queue, which will allow me to go ahead and start on packaging ghostty for debian. not sure if it'll make trixie, but we'll see.

[mitchellh]

Awesome. See this: https://github.com/ghostty-org/ghostty/blob/main/PACKAGING.md

If anything is bullshit in that let me know and I'll fix it up, but so far other packagers have had success.

[dankamongmen]

yep, i've seen it. i've currently got an MR out on salsa to add minisign support to uscan, which required touching perl =[.

i'm using -Doptimize=ReleaseFast. i'm not using the fetch-zig-cache.sh business nor zig build --fetch; that shit won't fly.

things look reasonable:
