# Addons can register to bashbot events at statup
# by providing their name and a callback per event
#
# If an event occours each registered event function is called.
#
# Events run in the same context as the main bashbot event loop
# so variables set here are persistent as long bashbot is running.
#
# Note: For the same reason event function MUST return imideatly!
# compute intensive tasks must be run in a nonblocking subshell,
# e.g. "(long running) &"
#  

# Availible events:
# on events startbot and init, this file is sourced
#
# BASBOT_EVENT_INLINE	inline query received
# BASBOT_EVENT_MESSAGE	any type of message received
# BASBOT_EVENT_REPLYTO	reply to message received
# BASBOT_EVENT_FORWARD	forwarded message received
# BASBOT_EVENT_CONTACT	contact received
# BASBOT_EVENT_LOCATION	location or venue received
# BASBOT_EVENT_FILE	file received

# all global variables and functions can be used in registered functions.
