# ocd-waybar-ctl: send a command to the ocd-waybar daemon.
# Usage: ocd-waybar-ctl {advance|lock|poll|quit}
# Wired into the waybar custom/ocd module as on-click / on-click-right.
#
# This must never hang: waybar runs it on a click and stops updating the
# module until it returns. socat's UNIX-SENDTO relay can block waiting on
# the datagram socket, so we use a small python sendto with a hard timeout
# instead. python3 is guaranteed present because the daemon itself needs it.
