Writing xchat scripts in Python (to play sound alerts)

I use xchat as my IRC client. Mostly I like it, but its sound alerts aren't quite as configurable as I'd like. I have a few channels, like my Bitlbee Twitter feed, where I want a much more subtle alert, or no alert at all. And I want an easy way of turning sounds on and off, in case I get busy with something and need to minimize distractions.

Years ago I grabbed a perl xchat plug-in called "Smet's NickSound" that did something close to what I wanted. I've hacked a few things into it. But every time I try to customize it any further, I'm hit with the pain of write-only Perl. I've written Perl scripts, honest. But I always have a really hard time reading anyone else's Perl code and figuring out what it's doing. When I dove in again recently to try to figure out why I was getting so many alerts when first starting up xchat, I finally decided: learning how to write a Python xchat script couldn't be any harder than reverse engineering a Perl one.

First, of course, I looked for an existing nick sound Python script ... and totally struck out. In fact, mostly I struck out on finding any xchat Python scripts at all. I know there are Python bindings for xchat, because there's documentation for them. But sample plug-ins? Nope. For some reason, nobody's writing xchat plug-ins in Python.

I eventually found two minimal examples: this very simple example and the more elaborate utf8decoder. I was able to put them together and cobble up a working nick sound plug-in. It's easy once you have an example to work from to help you figure out the event hook arguments.

So here's my own little example, which may help the next person trying to learn xchat Python scripting: chatsounds.py on github.
