Need help with destroy space when empty script

[tbsmn]

I guess I have something wrong here but I can't see it. Maybe someone here could help me.

Objective: Empty spaces should be destroyed when switched to another space. (To cleanup unused spaces)

Here is my code for achieving this:
yabai -m signal --add event=space_changed action='if [ $(yabai -m query --spaces --space $YABAI_RECENT_SPACE_ID | jq -re '.windows') = "[]" ]; then yabai -m space $YABAI_RECENT_SPACE_ID --destroy ; fi'
This actually destroys empty spaces but it seems to trigger randomly.

Any Ideas?

I finaly figured it out myself. The problem was that spaces have an "id" and an independent "index":
If anyone is interessted here is the code that works:

yabai -m signal --add event=space_changed action='RSINDEX=$(yabai -m query --spaces | jq ".[] | select (.id == $YABAI_RECENT_SPACE_ID) | .index") && if [ "$(yabai -m query --spaces --space $RSINDEX | jq -re '.windows')" = "[]" ] ; then yabai -m space $RSINDEX --destroy ; fi'

Thanks for posting the solution as well. I converted this to discussions and marked this as the correct answer.

Hmm, suddenly stopped working

jq: error: syntax error, unexpected ')' (Unix shell quoting issues?) at <top-level>, line 1:
.[] | select (.id == ) | .index                     
jq: 1 compile error

I just looked it up. It seems like I have changed the script a while ago. But I can't remember why.

I now use this in my .yabairc:

yabai -m signal --add event=space_changed action='~/scripts/destroy_empty_space.sh $YABAI_RECENT_SPACE_ID'

And destroy_empty_space.sh looks like this:

#!/usr/bin/env bash

RSINDEX=$(yabai -m query --spaces | jq ".[] | select (.id == $1) | .index")
SPACEISEMPTY=$(yabai -m query --spaces --space $RSINDEX | jq -re '."first-window"')

if [[ $SPACEISEMPTY = 0 ]] ; then
    yabai -m space $RSINDEX --destroy
fi

Maybe this will work for you too.
