Interactive editor

cf. my blog post: Integrating vim and irb.

Usage

$ gem install interactive_editor

Put the following in your .irbrc:

require 'rubygems'
require 'interactive_editor'

Then, from within irb:

$ irb
> vi
> vi 'filename.rb'
> [emacs|vim|nano|mate] ...

To try it out without installing the gem:

$ git clone git://github.com/jberkel/interactive_editor.git
$ cd interactive_editor
$ rake console
