4 # This script is a simple wrapper which prefixes each i3status line with custom
5 # information. It is based on:
6 # https://github.com/i3/i3status/blob/master/contrib/wrapper.py
7 #
8 # In ~/.i3status.conf, add the following line:
9 # output_format = "i3bar"
10 # in the 'general' section.
11 # Then, in ~/.config/i3/config or ~/.config/sway/config add:
12 # status_command i3status | my-i3status.py
13 # in the 'bar' section. Make sure my-i3status.py is in $PATH.
