My Google Wave Client

Google released a reference implementation of a Wave client and server in July, written in Java, that you can download and experiment with. When Mickaël Rémond wrote about using the reference implementation with ejabberd, I decided that it was time to get my hands dirty.

I got the reference implementation working, and I could chat with multiple participants in the console clients. However, I wanted to know more about what was happening behind the scenes in the client, and more importantly, the server (and how operation tranforms work).

So I decided to write my own client in Erlang that communicates with the reference server. This way I could investigate what was happening in the client and the server, and gain more knowledge about Wave. It required a bit of reverse engineering, and messing around with protocol buffers (the client communicates with the server using these), but it works nicely.

I've created a video to demonstrate it. Happy watching!

P.S. I used ngerakines's implementation of Erlang prototocol buffers, and the Nitrogen Web Framework.

P.P.S. I'm going on holiday for 2 weeks, so if I don't reply to comments, please be patient. I will do so when I get back...
