i3-get-window-criteria

	#!/bin/sh

	# i3-get-window-criteria - Get criteria for use with i3 config commands

	# To use, run this script, then click on a window.
	# Output is in the format: [<name>=<value> <name>=<value> ...]

	# Known problem: when WM_NAME is used as fallback for the 'title="<string>"' criterion,
	# quotes in "<string>" are not escaped properly. This is a problem with the output of `xprop`,
	# reported upstream: https://bugs.freedesktop.org/show_bug.cgi?id=66807
