# Script designed to work with i3blocks to return battery status to i3bar.
#
# This python  script  uses  acpi to get battery status and requires FontAwesome
# to be installed on your system.
#
# [*] see https://fortawesome.github.io/Font-Awesome/
# [*] key value  for "markup" has to be "pango" in  i3blocks config file.
