# Polybar launcher script written by Nathaniel Maia for use in ArchLabs
# Will launch bars depending on WM 
# Can also be used to reload openbox session with [--reload] or [-r]


# Enter your bar names here (seperated by spaces) eg. BARS=(bar bar1 my-bar)
# This will be combined with CUR_WM in WMS below  eg. openbox-bar, bspwm-bar1, i3-my-bar etc.
# by default it is set up in WM-BAR naming format
BARS=(bar)
