An IPython-Like Shell Environment for Ruby

Whenever I use Python, I always install IPython. Without it, things like tab completion are missing and the workflow becomes much less comfortable. The other day I wanted to experiment a bit with Ruby, so I looked for something similar and found a tool called Pry. You can install it with the following commands.

$ sudo apt-get install ruby rubygems
$ sudo gem install pry pry-doc
$ pry

It adds syntax coloring and tab completion, which makes it very convenient.
