# Addons can register to bashbot events at startup
# by providing their name and a callback per event
#
#### $$VERSION$$ v0.98-dev-70-g694ee61
#
# If an event occurs 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) &"
#
# Available events:
# on events startbot and init, this file is sourced
#
# BASHBOT_EVENT_INLINE inline query received
# BASHBOT_EVENT_MESSAGE any type of message received
# BASHBOT_EVENT_TEXT message containing message text received
# BASHBOT_EVENT_CMD a command is received
# BASHBOT_EVENT_REPLYTO reply to message received
# BASHBOT_EVENT_FORWARD forwarded message received
# BASHBOT_EVENT_CONTACT contact received
# BASHBOT_EVENT_LOCATION location or venue received
# BASHBOT_EVENT_FILE file received
#
# BAHSBOT_EVENT_TIMER this event is a bit special as it fires every Minute
# and has 3 meanings: oneshot, every time, every X minutes.
#
# all global variables and functions can be used in registered functions.
#
# parameters when loaded
# $1 event: init, startbot ...
# $2 debug: use "[[ "$2" = *"debug"* ]]" if you want to output extra diagnostic
#
# parameters on events
# $1 event: inline, message, ..., file
# $2 key: key of array BASHBOT_EVENT_xxx
# $3 debug: use "[[ "$2" = *"debug"* ]]" if you want to output extra diagnostic
#
