# purpose: provides interface to set/remove/modify regular expression triggers
|
|
# to execute a command.
|
|
#
|
|
# Usage: actiontrigger add <#channel or global> <capability> <repeat delay (in seconds)> <regex trigger> <command>
|
|
#
|
|
# Examples:
|
|
#
|
|
# Greet a nick when they join the channel:
|
|
# actiontrigger add #channel none 0 ^(?i)([^!]+)![^\s]+.JOIN echo Hi $1, welcome to $channel!
|
|
#
|
|
# Same, but via private message (set capability to "admin" to use `msg` admin command):
|
|
# actiontrigger add #channel admin 0 ^(?i)([^!]+)![^\s]+.JOIN msg Hi $1, welcome to $channel!
|
|
#
|
|
# Kick a nick if they say a naughty thing. Set capability to "can-kick" to use `kick` admin command.
|
|
# actiontrigger add global can-kick 0 "^(?i)([^!]+)![^\s]+.PRIVMSG.*bad phrase" kick $1 Do you talk to your mother with that mouth?
|
|
#
|
|
# Say something when a keyword is seen, but only once every 5 minutes:
|
|
# actiontrigger add global none 300 "some phrase" echo Something!
|
|
#
|
|
# Capture a part of somebody's message.
|
|
# actiontrigger add #channel none 0 "(?i)how is the weather (?:in|for) (.*) today" weather $1
|
|
#
|
|
# These are basic examples; more complex examples can be crafted.
