Check availability of yabai

[24unix]

What is the method with the least overhead to query if yabai is running?

Currently I fire a timer with this args:

		let yabaiArgs = ["-m", "query", "--displays"]

I guess it's not optimal?

PID and Socket can be leftovers when eg WindowManager crashed, can't they?

The socket and pid file can indeed be leftovers from a previous session. I’m not sure what the fastest command to run would be, but I’d probably just run:

yabai -m config window_shadow

Most commands take similar amount of time to run when it fails to open a connection to the socket because yabai is not running, however this command requires less processing from yabai in cases where it is running (and gets a response). The command above returns the current value of the shadow_setting and you can just discard the response as you already do with the query command in your sample.

Thanks for the reply, I tried it:

time yabai -m query --displays 0.01s user 0.00s system 49% cpu 0.019 total
time yabai -m config window_shadow 0.00s user 0.00s system 84% cpu 0.010 total

Seems to be the better solution.

I will adapt my code.
