xdotool getactivewindow getwindowpid

I tried this. But it's not working on Wayland. As far as i know. There is no focus window concept on Wayland. So can I get it from Mutter or GNOME-Shell?

I wish that ability too. My current best is using Looking Glass. "[Alt+F2] lg [Enter]" to open it. It does not tell pid but it shows app name, which I can then search in System Monitor and not have to look through tens of processes. There you can get PID or kill the app directly. I hope this helps.

The following works with Gnome 43:

Install https://extensions.gnome.org/extension/4974/window-calls-extended/
Run gdbus call --session --dest org.gnome.Shell --object-path /org/gnome/Shell/Extensions/WindowsExt --method org.gnome.Shell.Extensions.WindowsExt.FocusPID | sed -E "s/\('(.*)',\)/\1/g" to get the PID of the focussed window or use a different method.
