Set window name through a shell script

[JDuffe]

I had an idea to customize my tmux, but am not sure if this would even be possible:

I wrote a little bash script that truncates the current path to get only the first 3 letters of each "level" (i.e. ~/projects/abcdef gets converted to ~/pro/abc). This script alone works great and echo's out the shortened path.

I was wondering if there is a way to set the tmux window name through the output of a script, sth. like set -g @catppuccin_window_text "#(~/bin/my_script.sh)" (this obviously doesn't work, it's just to get the general idea).

Maybe this is also just really unnecessary and there is a built-in function in tmux/catppuccin to truncate a path like this, but I haven't found anything.

Any help is greatly appreciated!

What shell are you using?

Btw this plugin really doesn't do much, all the functionally you're thinking of exists in tmux itself.

I'm using zsh.

I figured that there probably exists something built in, but I didn't find anything. Can you provide a link to documentation about this?

tl;dr this is the job of your shell, do not change anything in your tmux config

zsh makes this hard, here's a function to set the terminal title:

 function set_terminal_title() {
  echo -en "\e]2;$@\a"
}

You'd call that in a hook every time you change directory with the output of your script.

Fish supports this natively: https://fishshell.com/docs/current/cmds/fish_title.html

Ok, I'll look into this. Thanks @kjnsn!
