# Script: bspc-subtract-presel
# Author: Henrik Lissner (w/ credit to @Chrysostomus)
# Usage:
# bspc-resize-to-presel
#
# (Adapted from Chrysostomus/bspwm-scripts/bin/resizetopresel.sh)
#
# This script resizes the current window by "subtracting" the bspwm preselection
# on the current node. In English, that means this will reduce the window's
# width by 20%:
#
# bspc node -p east -o 0.2 && bspc-subtract-presel
#
# NOTE: We use zsh for this because bash chokes on float arithmetic.
