Puppeteer for i3
Shamelessly stolen from [1]. Author of the original script also wrote very nice
blogpost [2] that is very much worth reading as well.
I ended up converting some of my bash magic scripts and moved them here.
Needs (Gentoo):
- dev-python/i3ipc
- dev-python/xcffib
- dev-python/python-evdev
- dev-python/dbussy::zyrenth
> eselect repository enable zyrenth
Configuration is loaded from config file ~/.config/i3master.conf with
syntax from Pythons ConfigParser.
