This module contains the basic callbacks for handling PRIVMSGs. Both Privmsg
|
|
and PrivmsgRegexp classes are provided; for offering callbacks based on
|
|
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
|
|
how to use them.

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.
