Quick and dirty alternative to mouse jump feature from Microsoft PowerToys.
pipe=${XDG_RUNTIME_DIR:-$HOME/.local}/mouse-trampoline.pipe
# or wherever you want to put this file
# start the daemon
mouse-trampoline $pipe
# show the window
echo > $pipe- Tkinter
- Pillow
- python-xlib
Should run as daemon for quicker response times. If you're a suckless.org fanatic and rather concerned about saving as much free PIDs as possible, git checkout v1.0.
This uses 3 (yes, three) connections to X server: one for Tk, one for python-xlib (to get/set cursor position), one for Pillow to take screenshot of the screen. Theoretically it's possible to reduce this number to 2 without complete rewrite, but blt::winop query yields X Error of failed request: BadWindow (invalid Window parameter) for some reason.
Not tested with multiple monitors.
Good luck writing similar thing for bazillion of Wayland compositors.
