Ibid finally released!

After over a year of development, we have finally released Ibid. Ibid is a general purpose chat bot written in Python. We've suffered from a bit of feature creep, so despite being a 0.1 release it can talk 7 messaging protocols and has over 100 features provided by plugins. I think we also have an excellent architecture and very developer friendly plugin API. The 0.1.0 release can be downloaded from Launchpad or installed from our PPA.

Playing with Python and IRC

I wrote three IRC bots in [Python][] this last week (although one was a rewrite). They probably aren't very useful to most people, but I'm going to share them anyway in case someone finds them interesting.

The first one was prompted by [Adrian][], who is maintaining a [countdown][] until his wedding as a factoid in [Spinach][]. Since [Knab][] doesn't actually support countdowns, it has to be updated manually. This clearly isn't the Right Way to do this, and so I hacked together a [script][irccountdown] which connects to IRC and teaches Spinach the updated factoid. I run this as a daily [cronjob][] to keep the countdown up to date.

As is usually the case with Python, there was already a library for accessing IRC, namely [irclib][]. It isn't documented very well, but has a couple example scripts which are fairly easy to follow. It follows an event based model, so you write functions which will be called when certain events occur (such as receiving a message).

The final of the [Currie Cup][] was held on Saturday (which my team (the [Sharks][]) won), and I followed the match online using [SuperSport's][] live score site1. I then thought that it would be cool to have the score announced on IRC when it changed, and since I was bored I wrote a simple [bot][rugby] to do this. It worked well, but was very simple in that it only supported one hardcoded channel and one hardcoded game.

Since I was also bored on Sunday I [rewrote][rugbybot] this bot properly. I added a subscription mechanism so that channels and users can subscribe and unsubscribe to games by sending the bot a command. It's mostly working except for listing the available games (since there aren't any rugby games coming up which means that I can't test it ;-) ). Games are specified by the ID used by SuperSport's site, and finding the right ID is currently a manual process.

  1. I'm not really a sports fan — I just enjoy bragging when we do win ;-)
