Ruby - irb tricks

In IRB, we can use vim to type a block of code easily. To do this imposible, all you need to do is create a file ~/.irbrc with content:

require 'rubygems'
require 'interactive_editor'

Don’t forget to run gem install interractive_editor before you do this. Now, in irb terminal, just call vi or vim, enter the block code and save it, this code will be run on irb.

Be nice with IRB and VIM. :)
