Hello!

I’m still using X11, and one of the things that’s keeping me there is that I make heavy use of a launch-or-focus script, so that I hit a certain hotkey and no matter what a browser/chat/editor/terminal/file-manager/etc. shows up focused on my current desktop.

In the world of Wayland, this isn’t so easy. If this can be recreated at all, I think it’ll have to be made to rely on some sort of interface to Kwin.

I don’t think it’s possible now, but might it be in the future?

Here’s my script, let’s see if the lemmy interface mangles it (EDIT: yes, the last character should be an ampersand, not &):

#!/bin/zsh -ex

# -- Usage --
# ./toggle_window.zsh LAUNCH_CMD [ WM_CLASS [ CHECK_CMD ] ]

# -- Defaults --
# WM_CLASS and CHECK_CMD each default to the value of LAUNCH_CMD

# -- Examples --
# ./toggle_window.zsh dolphin
# ./toggle_window.zsh wezterm-gui org.wezfurlong.wezterm
# ./toggle_window.zsh firefox firefox firefox-bin
# ./toggle_window.zsh \
#   'flatpak run --branch=stable --arch=x86_64 --command=telegram-desktop --file-forwarding org.telegram.desktop' \
#   telegram-desktop telegram-deskto
# Yes, "telegram-deskto" without a final p. Hmm.

# -- Dependencies --
# - procps (pgrep)
# - wmctrl
# - x11-utils (xprop)
# - xdotool

# -- TODO --
# - wayland

launch_cmd=(${(z)1})
wm_class=${2:-$1}
check_cmd=${3:-$1}

if [[ $(xprop -id $(xdotool getactivewindow) WM_CLASS) =~ \"$wm_class\" ]] {
  xdotool getactivewindow windowminimize
} else {
  wmctrl -xR $wm_class || true
}

pgrep -u $USER -x $check_cmd || exec $launch_cmd &

    What’s the idea behind installing, uninstalling, reinstalling, uninstalling… all the time?

      It was the best way I found to do it, because I couldn’t find a proper way to run a kwin script with an argument (the program name and class), so I decided to just modify the script and then install and run it, and uninstall at the end. “Install” only takes a blink, although it may be made faster, for example implementing a sort of “caching” of the last used script in order to avoid removing and reinstalling the same script, perhaps one day I’ll try to implement it. My first attempt at it was done using KWindowSystem api, but something didn’t work so I had to give up and just install the scripts. perhaps I can try again with PlasmaWindowManagement, I may be luckier
