Episode #561
Building a REPL

If you're anything like me you use a read-eval-print-loop such as IRB or Pry as a daily assistant to your Ruby development process. But how do these tools work, anyway? In today's episode, guest chef Adam Fernung is going to show you how to build a simple REPL of your own. In the process, you'll learn more about how Ruby's dynamic variable reflection works---which will give you a better idea of how to debug Ruby code and create development tools of your own. Enjoy!
