This file collects methods to handle ‘stream filters’, a generic mechanism to transform text+attributes into other text+attributes
Giuseppe “Oblomov” Bilotta <gmail at giuseppe.bilotta.com>
These routines read a string and return the number of seconds they represent.
This module takes care of language handling for rbot: setting the core.language value, loading the appropriate .lang file etc.
The move of everything rbot-related to the Irc::Bot::* namespace from Irc::* would cause off-repo plugins to fail if they register any configuration key, so we have to handle this case.
Giuseppe Bilotta (gmail at giuseppe.bilotta.com)
This module defines the Irc::Client class, a class that can handle and dispatch messages based on RFC 2821 (Internet Relay Chat: Client Protocol)
This would be a good idea if it was failproof, but the truth is that other methods can indirectly modify the hash. sigh
class AuthNotifyingHash < Hash
%w(clear default= delete delete_if replace invert merge! update rehash reject! replace shift []= store).each { |m| class_eval { define_method(m) { |*a| r = super(*a) Irc::Bot::Auth.manager.set_changed r } } }
end
The Irc module is used to keep all IRC-related classes in the same namespace
Define standard IRC attriubtes (not so standard actually, but the closest thing we have …)
