+=begin rdoc
+ BotModule is the base class for the modules that enhance the rbot
+ functionality. Rather than subclassing BotModule, however, one should
+ subclass either CoreBotModule (reserved for system modules) or Plugin
+ (for user plugins).
+
+ A BotModule interacts with Irc events by defining one or more of the following
+ methods, which get called as appropriate when the corresponding Irc event
+ happens.
map(template, options)::
map!(template, options)::
- map is the new, cleaner way to respond to specific message formats
- without littering your plugin code with regexps. The difference
- between map and map! is that map! will not register the new command
- as an alternative name for the plugin.
+ map is the new, cleaner way to respond to specific message formats without
+ littering your plugin code with regexps, and should be used instead of
+ #register() and #privmsg() (see below) when possible.
+
+ The difference between map and map! is that map! will not register the new
+ command as an alternative name for the plugin.
Examples:
plugin.map 'karmastats', :auth => 'karma'
# maps can be restricted to public or private message:
- plugin.map 'karmastats', :private false,
- plugin.map 'karmastats', :public false,
- end
+ plugin.map 'karmastats', :private => false
+ plugin.map 'karmastats', :public => false
+
+ See MessageMapper#map for more information on the template format and the
+ allowed options.
listen(UserMessage)::
Called for all messages of any type. To
privmsg(PrivMessage)::
Called for a PRIVMSG if the first word matches one
- the plugin register()d for. Use m.plugin to get
+ the plugin #register()ed for. Use m.plugin to get
that word and m.params for the rest of the message,
if applicable.
Called when a user (or the bot) changes a channel
topic
- connect():: Called when a server is joined successfully, but

before autojoin channels are joined (no params)
