Using irb with your Ruby? Yeah, I thought so.
If you want syntax coloring, ri inside irb and a shorter prompt, get Wirble:
sudo gem install wirble
And add an .irbrc file to your home directory, following Wirble’s advice on what to put there.
Oh, and when you have one of those, you could add Ben Bleything’s command history [...]
