Needless to say, we can't live without irb. Although it is already incredibly useful, I had a desire to improve it...

like this:

This is the irb_rocket that I've made. It makes irb into being as follows

• Result follows blue #=> after your input.
• It also be colored by Wirble.
• Output of stderr is colored to red.

INSTALL

You must install Wirble and ruby-terminfo in advance. And then, you can install the plugin like this:

   1  % sudo gem install irb_rocket --source http://merbi.st

After that, the last task is append 2 lines below to your ~/.irbrc

   1  require 'rubygems'
   2  require 'irb_rocket'

Completed! Now you can use new irb as always.
