I have a love/hate rela­tion­ship against the hello mes­sages shown in all the world lan­guages on flickr. That’s why this morn­ing I was talk­ing with a friend on IRC about this and a bad idea jumped in my mind: do an IRC bot that says hello in many lan­guages when some­one joins a channel.

It’s from sev­eral years that I don’t do any­thing IRC related, but this time I had two spe­cial weapons in my back­pack: python and twisted. The final bot is ~90 lines of code, half of the which are for the hello list and the entire coding process took less than 20 minutes.

Here fol­lows the bot source code; note that this is in ital­ian but could be easily trans­lated in your lan­guage:

#!/usr/bin/env python
# vim: set fileencoding=utf-8 :

from twisted.words.protocols import irc
from twisted.internet import reactor, protocol

import random

class HelloBot(irc.IRCClient):
    nickname = "Hola"
    channel = "channel"
