Re: kill session using hook and session_name variable
I don't think my tmux does support multiline quotes :( however i have it
working with this:
set -g remain-on-exit on
set-hook -g pane-died {
if -F "#{&&:#{==:#{window_name},netkit-vm},#{==:#{pane_index},0}}" {
run-shell "tmux -L netkit has-session -t '=#{session_name}-dead' &&
tmux kill-session -t '=#{session_name}-dead'; tmux -L netkit rename-session
-t '=#{session_name}' '#{session_name}-dead'"
} {
run-shell "tmux -L netkit kill-pane -t
#{session_name}:#{window_name}.#{pane_index}"
}
}
Thanks for your help!!

Re: kill session using hook and session_name variable
if-shell does not expand formats in its command arguments for some reason.
Also this will not work if the old session does not exist, because the
kill-session will fail so the rename-session will not run.
You need to wrap it in run-shell which does expand formats, and run them as
separate commands:
set -g remain-on-exit on
set-hook -g pane-died {
if -F "#{&&:#{==:#{window_name},netkit-vm},#{==:#{pane_index},0}}" {
run-shell "
tmux kill-session -t '=#{session_name}-dead'
tmux rename-session -t '=#{session_name}' '#{session_name}-dead'
"
}
}
If your tmux is too old for multiline "s, then you will have to do "tmux
kill-session ...; tmux rename-session ...".
If you are using a tmux which is older and does not support {}, quoting
will be quite annoying. Personally I would probably put the whole hook in a
shell script and just pass in #{session_name} #{window_name} and
#{pane_index} as arguments:
set-hook -g pane-died 'run-shell "/path/to/my/script \"#{q:session_name}\"
\"#{q:window_name}\" #{pane_index}"'
Then you can do whatever you like in the script (but be careful of races
with multiple separate tmux commands).

kill session using hook and session_name variable
Hi,
I think I've got the wrong syntax for this, any pointers would be
appreciated!
```
# If pane 0 dies, kill any previous MACHINE-dead sessions, and rename this
session
# from MACHINE to MACHINE-dead
set-hook -g pane-died 'if -F
"#{&&:#{==:#{window_name},netkit-vm},#{==:#{pane_index},0}}" "kill-session
-t #{session_name}-dead; rename-session #{session_name}-dead" "kill-pane"'
```
I'm trying to make it so that if the process in window netkit-vm, pane 0
dies, then the session gets renamed to append '-dead' to the current name
(session a > session a-dead), however it needs to kill the -dead sessions
of the same name before, otherwise rename-session would fail as it would be
a duplicate session.
The if statement seems to be working fine but kill session is failing (i
get a message in the status bar showing the correct usage of kill-session).
Are there some escape characters I'm missing for the variables?
Thanks,
Billy
