# Script to show current keyboard layout in i3status bar
# Requires https://github.com/nonpop/xkblayout-state
# Inspiration from https://github.com/vzaliva/scripts_and_configs/blob/master/scripts/i3status.sh

# set your keymap as you wish
# ex: setxkbmap -layout 'us,us,fr' -variant 'mac,colemak,oss' -option grp:ctrls_toggle -option caps:escape
