Feature Request: Don't draw border for specific apps

[ghost]

Can we exclude certain apps while drawing the border? Yabai had that option and it is crucial for some apps to function in my setup.

For e.g. slack has a had time with huddle when border is on

I think some kind of blacklist feature would be a good idea and should be easy to implement.

I.e. here we already have the application pid: https://github.com/FelixKratz/JankyBorders/blob/ab4d6fce4b8fda3ae32c997dcab9e50118b5d864/src/windows.c#L14-L16 and could use it to get the process name and check a blacklist. If the blacklist hits, we simply return early (just as we do if the window belonge to our pid).

Pull requests are welcome.

If you just want to exclude a single app, this patch has been working for me to exclude the bloated mess Adobe Illustrator. Just need to change to Slack and it should work:

The blacklist functionality has been added on master, it works to following way:

borders blacklist="System Settings,Safari,kitty"

where a comma separated list of application names can be supplied. These are excluded from being bordered.

Thanks a lot @FelixKratz for this; it was a swift implementation :D

@FelixKratz I just installed with --HEAD and borders blacklist="Sublime Text" doesn't work. Am I missing something? Thanks for the awesome tool!

~It would be great if we can have a whitelist as well 😁~

Edit: there is a whitelist arg

@diocletiann Sublime's executable is named sublime_text instead. You can check this using the top command in the terminal
