#Description:
|
|
# This script defines just a mode for rofi instead of being a self-contained
|
|
# executable that launches rofi by itself. This makes it more flexible than
|
|
# running rofi inside this script as now the user can call rofi as one pleases.
|
|
# For instance:
|
|
#
|
|
# rofi -show powermenu -config ~/.config/rofi/powermenu.rasi
|
|
#
|
|
#Dependencies:
|
|
# <None>
|
|
#
|
|
# shellcheck disable=all
