You've heard of Pry right? It's a full-featured alternative to the classic IRB shell that we use in Ruby, and it's awesomesauce. If you've ever felt like you wanted a crowbar to pry open your code during runtime... well, Pry is your answer.

Pry is essentially a REPL (read–eval–print loop) tool that you can use to examine and debug your code. One of the best features is that local variables are available to Pry, saving you from recreating them as you normally would in an IRB session.
