Slava Pestov, the creator of Factor, has a post on FUEL — Factor’s Ultimate Emacs Library, an emacs major mode for writing Factor code. Patterned after SLIME (for Common Lisp), FUEL includes goodness like (Factor)word completion, code and documentation browsing and even some refactoring support!. Checkout the screencast linked in the above post to see the features in action.

As an emacs fan, I’m thrilled that Slava is now an emacs user and I also enjoy his anti-Java rants (most of them I agree with). jEdit though is a nice editor especially the remote editing interface.

I’ve been writing Smalltalk code since last year and I think I’m now accustomed to image based programming environments. Factor is at the top of the pile of programming languages to learn this year and I expect FUEL to make it an enjoyable experience.
