Suggestion: Red color when pane is dead

[tzachshabtay]

We run xpanes with a lot of micro-services and sometimes it's hard to see when a service dies. It would be nice if the Pane is dead message was colored red, or even better, it the pane name label background changed from green to red when that happens.

Great idea!
I think I can add new shell variable to change the format of the default message.
And it might be better to make the default message have red background.

I will work on it next release.
But it may take much time due to my another work.
Stay tuned.
Or, pull requests are always welcome if you hope :)

even better, it the pane name label background changed from green to red when that happens.

Executing tmux select-pane -T "#[bg=red,fg=black] #T #[default]" is the workaround as of xpanes v4.1.0

$ xpanes -tsc 'YOUR_COMMAND; tmux select-pane -T "#[bg=red,fg=black] #T #[default]"' _

Default message can be changed by TMUX_XPANES_PANE_DEAD_MESSAGE variable.
See https://github.com/greymd/tmux-xpanes#tmux_xpanes_pane_dead_message

This feature was released at v4.1.1.

Great, thanks!
When are you going to upload to brew?

[greymd]

After this PR is merged, you'll be able to use it. (Many thanks @bepsvpt !).
Homebrew/homebrew-core#39580

Have a ☕️ and wait.

While waiting I tried using the select-pane as you described but it doesn't seem to work correctly -> it sometimes marks the wrong panes in red.
From looking at man tmux I didn't see what's the behavior for select-pane when you don't provide a target pane with -t, but I guess it doesn't do what we want it to do (i.e to use the pane we're running from).
I didn't see a built-in way in tmux to get the pane id from which we're running, is there maybe a variable that xpanes provides for this?

As you pointed out, my workaround does not work as expected, sorry.

We can get index number of pane like this.

tmux display -pt "${TMUX_PANE}" "#{pane_index}"

And, this workaround works in my environment.

$ xpanes -tsc 'INDEX=`tmux display -pt "${TMUX_PANE}" "#{pane_index}"`; sleep {}; tmux select-pane -t $INDEX -T "#[bg=red,fg=black] #T #[default]"' 1 2 3 4 5 6 7

To register the alias of xpanes command might be helpful for you.
