This is a simple IRC recent changes bot that works perfectly on all wikimedia wikis. You can change «print data» with another command to begin scanning the change.

As it is configured now, it will work with en.wikipedia, en.wiktionary and meta.wikimedia; of course you can change these values by changing the variable channels. 

######## IRC CONFIGURATION ########
server = 'irc.wikimedia.org'
port = 6667
nickname = 'rc'
channels = ['en.wikipedia', 'en.wiktionary', 'meta.wikimedia']
