Pico IRC Bot using circuits in 24 Lines of Code.

pbot.py

from circuits import Component
from circuits.net.sockets import TCPClient, connect
from circuits.net.protocols.irc import IRC, PRIVMSG, USER, NICK, JOIN, RPL_ENDOFMOTD, ERR_NOMOTD  # noqa


class PBot(Component):

    def init(self, host, port=6667):
        self.target = (host, port)
        self += (TCPClient() + IRC())

    def ready(self, *args):
        self.fire(connect(*self.target))

    def connected(self, host, port):
        self.fire(USER("pbot", self.target[0], self.target[1], "pbot"))
        self.fire(NICK("pbot"))

    def numeric(self, source, target, numeric, args, message):
        if numeric in (RPL_ENDOFMOTD, ERR_NOMOTD):
            self.fire(JOIN("#circuits"))
            self.fire(PRIVMSG("#circuits", "Hello World!"))

PBot("irc.freenode.net").run()

This is in response to Python: IRC client in 19 lines which I can't beat in circuits but nevertheless 24 Lines of Code is still pretty good for a framework like circuits.

Enjoy!

Upon further review of the article this gist is challenging, I notice that there are a few bugs off the bat.

• connected is never set to True
• The 19 loc bot will fail miserably on imperfect server responses.
• The 19 loc bot will likely not succeed in connecting or joining the channel due to various edge cases.

Note: The pbot.py example above is based on the circuits framework and the ircbot.py example.
