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 ;-) 

Sharing links from Konqueror, including to IRC

I follow the main feeds of a couple social news sites (namely Digg, Reddit and Muti). When I find an article which I like, I go back and vote it up on the site. However, when I come across good articles via other sources, I don't submit them to these news sites (or try to find out if they've already been submitted) simply because it's too much effort.

When I started aggregating my activity on these sites on my blog and on FriendFeed, I needed a way to share pages that I didn't get to via one of these social news sites. I ended up setting up Delicious because I found a plugin for Konqueror which made it easy to bookmark pages.

I still wanted to solve the original problem though, and so started looking for an easy way to submit links to these sites from Konqueror. Konqueror has a feature called service menus which allows you to add entries to the context menu of files. I then needed to work out how to submit links to these services, which turned out to simply involve loading a URL with a query parameter specifying the link you want to share.

I created entries for Reddit, Digg, Muti, Delicious, Facebook and Google Bookmarks. These take you to the submission page of the service where you can fill in the title1. Digg and Reddit will show existing submissions if the link has already been submitted.

I often share links on IRC, and wondered if I could integrate that with my menu. It turns out that WeeChat has a control socket, and I could send messages by piping them to the socket. I therefore wrote a script which prompted me for a headline or excerpt using kdialog, and then sent the link to the specified channel. My menu now looks like this:


If you want to set this up yourself, download share.desktop and put it in ~/.kde/share/apps/konqueror/servicemenus. If you want the icons, download shareicons.tar.gz, extract them somewhere, and fix the paths in social.desktop2. To setup the IRC feature (assuming you're using WeeChat), download and save it in ~/bin/. You will need to change the commands in social.desktop depending on the servers and channels you wish to use.

  1. One shortcoming is that the title of the page is not automatically filled in. 

  2. I couldn't work out how to use relative paths, or ~. 

Vim syntax highlighting for irssi IRC logs

When I occasionally read [IRC][] logs saved by [irssi][], I find the lack of colouring rather annoying and find that I can't read them very quickly. I finally got round to writing a syntax highlighting plugin for [Vim][] in order to correct this. The colours could probably do with some improvement, but it's much better than before.

In case anyone else finds this useful, I have attached the plugin to this post. To use it, save [irssilog.vim][irssilog.vim] in ~/.vim/syntax/ and enter the following command to use it with the current file.

:set syntax=irssilog

If you want Vim to automatically detect the file type, add the following to ~/.vim/ftdetect/irssilog.vim1.

au BufRead,BufNewFile */irclogs*.log    set filetype=irssilog

  1. This relies on the logs being stored in the default location of ~/irclogs/
