commands and their arguments (much like *nix command line programs) use the

Privmsg class; for offering callbacks based on regular expressions, use the

PrivmsgRegexp class. Read their respective docstrings for more information on

|
Much more primitive, but more flexible than the 'normal' method of using
|
|
the Privmsg class and its lexer, PrivmsgRegexp allows you to write
|
|
callbacks that aren't addressed to the bot, for instance. There are, of
|
|
course, several other possibilities. Callbacks are registered with a
|
|
string (the regular expression) and a function to be called (with the Irc
|
|
object, the IrcMsg object, and the match object) when the regular
|
|
expression matches. Callbacks must have the signature (self, irc, msg,
|
|
match) to be counted as such.
|
|
|
|
A class-level flags attribute is used to determine what regexp flags to
|
|
compile the regular expressions with. By default, it's re.I, which means
|
|
regular expressions are by default case-insensitive.
|
|
|
|
If you have a standard command-type callback, though, Privmsg is a much
|
|
better class to use, at the very least for consistency's sake, but also
|
|
because it's much more easily coded and maintained.
