Doesn't work if sxhkd is run as a systemd service. about pidswallow HOT 3 CLOSED

I don't think its a problem with sxhkd. your pstree output looks what it should be. Launch a gui app from terminal (Eg: mpv). And then provide the verbose output. If it works perfectly launching from term let me know. (As i intend to make the installation more simple).

Alright here's me starting Alacritty from a sxhkd shortcut, and running mpv.

systemd (sxhkd.service):

$ bspc subscribe node_add node_remove | grep -o --line-buffered '0x[0-9A-F]\+$' | xargs -n1 ./pidswallow
systemd(727)---alacritty(3425)---zsh(3430)
systemd(727)---alacritty(3425)---zsh(3430)---mpv(3535)

bspwmrc autostart (sxhkd &):

$ bspc subscribe node_add node_remove | grep -o --line-buffered '0x[0-9A-F]\+$' | xargs -n1 ./pidswallow
alacritty(6485)---zsh(6493)
alacritty(6485)---zsh(6493)---mpv(6570)
mpv(0x06A00002) swallowed alacritty(100663300)
0x06A00002 vomited 100663300

As you can see, it works if sxhkd is not a systemd service.

Ok, I finally understand the script completely haha. So yeah, the problem here is indeed systemd is in the way. But more importantly, the problem is we're not swallowing the immediate parents.

This problem can also be reproduced by running a terminal process inside another terminal process. The first terminal is gonna get swallowed, while it should be the second one.

I found this. I think this is a great way to implement it, since it doesn't rely on pstree output. I'll play around with it and if it works I'll create a pull request.
