Yi, the haskell editor

My latest shinything fascination is with Yi, an emacs-like editor written in Haskell. State! GUIs! Monads! What fun. It is entirely made of awesome.

It’s not the easiest program to start playing with, so I’ve written up some installation instructions and a beginner guide here. If you want to see what a real-world Haskell application looks like, yi is a great example.
