A short tiling script. Goals include minimal dependencies and few LOC, as it is to run in qubes os dom0.

tiling.py

#!/usr/bin/python2.7

# tiling.py
# Simple tiling for GTK
#
# NB: most of this was cribbed from some poor dev who isn't going to get
# the credit until I find his blog post again. Hopefully will update with
# the source shortly :-|
#
# `tiling.py width height x y -d 1`
# All dimensions and coordinates are given as percentages of the screen,
# so `tiling.py 50 50 25 25 -d 1` would give you a window that's 50% of your
# screen's height and width, and positioned in the center of your screen.
# The `-d` argument indicates the presence (1) or absence (0) of window
# decorations. Remember to give the script executing right with
# `chmod +x tiling`.
#
# Warning: This solution is not particularly beautiful, and of course has
# no warranty express or implied, and may break the universe, set your dog
# on fire, or make a politician into a real human being.
