2021-10-23 00:00:07 +0000 <L29Ah> how do you ppl set and revert terminal emulator window titles?
2021-10-23 00:00:24 +0000 <L29Ah> vim does that somehow, but i couldn't understand what's going on after reading its and urxvt's source code
2021-10-23 00:01:41 +0000 <liskin> L29Ah: vim cheats, it reads it by looking at the WINDOWID env var and then going through X
2021-10-23 00:02:35 +0000 <liskin> there isn't any better way, really. xterm has escapes for that but these are by default disabled presumably for security reasons, and urxvt doesn't have that at all
2021-10-23 00:03:32 +0000 <geekosaur> interestingly those escapes are not disabled in the mate and gnome terminal emulators
2021-10-23 00:03:42 +0000 <geekosaur> (but what they accept is sanitized)
2021-10-23 00:04:41 +0000 <geekosaur> so my prompt+etc. setup sends a bunch of escapes to set the window and icon titles (the latter is often used by taskbars/pagers)
2021-10-23 00:05:18 +0000 <liskin> hm, sanitizing probably helps, but it's still risky
2021-10-23 00:05:45 +0000 <liskin> if you're in a root shell, you don't want anything asking the terminal to dump the title to the pty input
2021-10-23 00:06:17 +0000 <geekosaur> that's a different set of escapes though
2021-10-23 00:08:50 +0000 <L29Ah> liskin: i see some code that supposedly should output the title in urxvt but it doesn't for me
2021-10-23 00:09:29 +0000 <L29Ah> ahh it's disabled for security's sake
2021-10-23 00:10:36 +0000 <liskin> well vim does weird shit
2021-10-23 00:11:12 +0000 <geekosaur> one thing that gets me about all this is $WINDOWID is as much of a security violation as the others, possibly more so
2021-10-23 00:11:13 +0000 <liskin> like I had to hack the terminfo entry to contain the word "xterm" otherwise some stuff wouldn't work: https://github.com/liskin/dotfiles/blob/home/.terminfo/terminfo.src#L1
2021-10-23 00:11:25 +0000 <L29Ah> http://www.shelldorado.com/scripts/cmds/xtitle great i found some $WINDOWID kludges
2021-10-23 00:15:21 +0000 <liskin> note that vim only uses WINDOWID for reading, it uses \033]0;…\007 to set the title as any other terminal program should
2021-10-23 00:15:26 +0000 <liskin> it wouldn't work in tmux otherwise
2021-10-23 00:16:11 +0000 <liskin> (it's still crazy to use WINDOWID in tmux but it usually works)
2021-10-23 00:18:10 +0000 <geekosaur> oh. yeh, I only ever set it
2021-10-23 00:18:30 +0000 <geekosaur> use wrappers around commands that change the title themselves to restore it
2021-10-23 00:19:06 +0000 <geekosaur> also wrappers around things that change state I show in the prompt and/or titlebar
2021-10-23 00:19:56 +0000 <liskin> well it's a bit silly that vim will only set the title if it thinks it can restore it, as many people configure their shell to just reset it in PROMPT_COMMAND
2021-10-23 00:20:25 +0000 <liskin> (although it quite likely can be overridden somehow, I haven't had to go that deep fortunately)
2021-10-23 00:21:23 +0000 <geekosaur> I'd use that but it actually takes a while to generate all the information I stuff in there so I optimize to only regen it when needed

2021-10-23 06:12:55 +0000 <Solid> 08:05 <liskin> [01:52:14] so I guess I'll leave this bit for Solid to tackle as he originally suggested that :-) << fair enough :)
2021-10-23 06:13:17 +0000 <Solid> though I'd hope that most changes (like the XDG handling) are backwards compatible and thus wouldn't necessarily be "breaking changes" as such
2021-10-23 06:15:08 +0000 <Solid> some things are _technically_ breaking changes (like changing `data T = T { a :: !A }` to `newtype T = T { a :: A }` ostensibly changes the strictness behaviour slightly) but I'd hope no one relies on these
2021-10-23 06:22:42 +0000 <Solid> as for the email I'd go for a proper plain text version of that markdown file (possibly shortened, but not necessarily)

2021-10-23 11:56:37 +0000 <liskin> hm, the Virtual Haskell Cohack is today: https://www.meetup.com/NY-Haskell/events/280998863
2021-10-23 11:56:58 +0000 <liskin> but writing a release announcement isn't exactly an exciting thing for a hackathon, is it?
2021-10-23 12:00:42 +0000 <geekosaur> not really. and it's somewhat badly timed wrt the release
2021-10-23 12:00:50 +0000 <geekosaur> unless we want a headstart on 0.18
2021-10-23 12:15:57 +0000 <liskin> it's just me still thinking that these events are something that I should enjoy, and every time I try it's a bit of a disaster :-)
2021-10-23 12:16:40 +0000 <liskin> like zurihac, I couldn't focus on a thing and it took me days to catch up with the talks I wanted to see, I have no idea how anyone manages to actually hack on something as well
2021-10-23 12:17:18 +0000 <liskin> on the other hand zurihac have us the sublayouts window swallowing contribution which I enabled a couple days ago and it's awesome
2021-10-23 12:17:35 +0000 <liskin> so here I am again thinking what to do to make the most of the cohack :-/
2021-10-23 12:17:43 +0000 <liskin> s/have us/gave us/
2021-10-23 12:20:16 +0000 <geekosaur> sounds like my life tbh
2021-10-23 12:32:14 +0000 <Solid> last time that cohack thing relied on using proprietary video conferencing software :/
2021-10-23 12:32:41 +0000Solidis busy for the rest of the day anyways, though
