# Project: Agnostic scratchpad/dropdown terminal that works on most window managers
# Dependencies: wmctrl, xprop, xdo, xdotool
# NOTE: Ensure script is included in system's path and can therefore be invoked with the command 'scratchpad'.
# Furthermore make sure the terminal is using x11 as a backend in wayland to allow this to work.
# Example: wezterm.lua: enable_wayland = false,
# kitty.conf: linux_display_server x11
# Set the environment variables to x11 to allow working in Wayland
#export GDK_BACKEND=x11
#export QT_QPA_PLATFORM=xcb
#export WAYLAND_DISPLAY=""
#export WINIT_UNIX_BACKEND=x11
#export WAYLAND_DISPLAY=wayland-0
