tmux.conf: use brackets for if-shell commands

[crpb]

• it's easier to read \ó/

Nice idea, thanks! Not sure how backwards compatible this is (you've confirmed with bullseye according to IRC), basically LGTM, leaving the +2 to @jkirk :)

From IRC: we seem to have issues with tmate, to be clarified :-/

[crpb]

Sadly it seems (fooding old) tmate isn't liking any of those {}

test@obelix:~$ grep '[{}]' /etc/tmux.conf
bind-key B if-shell '! tmux has-session -t bg' {
...
}
test@obelix:~$ tmate
lost server

ant it already complains about this new thing

grml-etc-core/etc/tmux.conf

Line 65 in d891ce5

if-shell "command -v hostname && hostname --help | grep -q -- -I" { set -g status-right "#[fg=green](net: #(hostname -I | sed -e 's/ [^ ]*:.*$//;s/ / | /g;s/ | $//')) #[fg=yellow]%Y-%m-%d %H:%M" } { set -g status-right '#[fg=yellow]%Y-%m-%d %H:%M' }

Maybe tmate needs to unlearn about /etc/tmux.conf 🙈

This needs at least a rebase, and also the tmate issue needs to be sorted out.

thougts? https://salsa.debian.org/cb/tmate/-/commit/0dae773b26e929bb448f29a60aeb8fe0b45c42a0

did that land in forky?

i'd be ok with it being broken on trixie (if it works in forky), duno about the others.

on second thought, doing this for grml-etc-core would be bad. users expect better backwards compat.

[crpb]

did that land in forky?

no, i only created that here for me today to see if it works and it does.
but yeah, it would break even trixie if send in and then even accepted with this /etc/tmux.con

I'd love to have https://salsa.debian.org/cb/tmate/-/commit/0dae773b26e929bb448f29a60aeb8fe0b45c42a0 available, but I agree, we shouldn't break backwards compatibility. :-/
