package Plugins::ActionTrigger;

# purpose: provides interface to set/remove/modify regular expression triggers
|

# to execute a command.
|

#
|
||||
# Examples:
|
||||
#
|
||||
# actiontrigger add #channel 0 0 ^(?i)([^!]+)![^\s]+.JOIN echo Hi $1, welcome to $channel!
|
||||
# actiontrigger add global 0 0 ^(?i)([^!]+)![^\s]+.PRIVMSG.*bad_word kick $1 That's a naughty word!
|
||||
# etc
|
||||
#
|
||||
# These are basic examples; more complex examples can be crafted.
