Set border options per space

[benallan]

I tried setting border options for specific spaces but it seems like the settings were applied globally to all spaces.

yabai -m config --space 2 window_border_width 4
yabai -m config --space 2 window_border off

Maybe this isn't supported?

What I'd really like to do is disable borders for spaces where I always use fullscreen windows since I think it looks better, but keep borders on spaces where I have a bsp layout with mutliple windows.

This is not supported as can be seen below.

$ yabai -m config window_border off
$ yabai -m config --space 1 window_border on
$ yabai -m config --space 1 window_border
on
$ yabai -m config --space 2 window_border
on

You can, however, quite easily work around this: Create signals for the application_launched, window_created and space_changed events.

• In the action for event=application_launched, query for all windows whose border is enabled, whose space index is one of the target spaces and whose PID is $YABAI_PROCESS_ID and toggle their border.
• In the action for event=window_created, query for the window whose window id is $YABAI_WINDOW_ID and if its space index is one of the target spaces and its border is enabled, toggle its border.
• In the action for event=space_changed, if the index of the space whose space id is$YABAI_SPACE_ID is one of the target spaces, query for all windows on that space whose border is enabled and toggle their border.

Thanks a lot for the suggestions. I installed from HEAD to get the $YABAI_ env variables, and then realised that could I probably use a much simpler set up (avoiding any spaces logic), triggering on the window_resized signal:

• If a window is zoom-fullscreen, then turn the border off.
• If a window is not full screen, turn the border on.

The border toggle logic works fine, but it seems to cause a weird side effect:

• Press zoom-fullscreen shortcut to fullscreen window: works ok.
• Press shortcut again to disable fullscreen: works ok.
• Press shortcut again to try to fullscreen window: fails. The window flickers and briefly changes to fullscreen size but immediately returns to normal size (not fullscreen). I inspect the window properties I see that zoom-fullscreen is set to 1.
• Toggle twice more (-> normal -> fullscreen) and full screen works the next time.

So every second attempt to fullscreen the window fails while I'm using my signal settings. I wonder what might cause this?

yabairc:

yabai -m signal --add event=window_resized action="$HOME/bin/yabai_borders.sh"

yabai_borders.sh:

#!/bin/bash

is_fullscreen=$(yabai -m query --windows --window "$YABAI_WINDOW_ID" | jq -re '.["zoom-fullscreen"]')
has_border=$(yabai -m query --windows --window "$YABAI_WINDOW_ID" | jq -re '.["border"]')

if [[ "$is_fullscreen" -eq "1" ]]; then
  if [[ "$has_border" -eq "1" ]]; then
    yabai -m window "$YABAI_WINDOW_ID" --toggle border
  fi
else
  if [[ "$has_border" -eq "0" ]]; then
    yabai -m window "$YABAI_WINDOW_ID" --toggle border
  fi
fi

Toggling border would cancel the windows zoom. Fixed on master.

Works great now, thanks a lot!
