# 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]

# I reccomend using al-polyzen to set up a session for each wm
# then ditching this method and adding the following line to your autostart
#                   sleep 1; al-polybar-session &


# Enter your bar names here (seperated by spaces)           eg. BARS=(bar1 bar2...)
# This will be combined with window manager from WMS below  eg. openbox-bar1, openbox-bar2...
# by default it is set up in WM-BAR naming format           eg. i3-bar, openbox-bar, bspwm-bar....
BARS=(bar)
CONFIG=$HOME/.config/polybar/config
WMS=(bspwm i3 openbox xfce awesome)
