The purpose of a debugger ruby-debug is to allow you to see what is going on “inside” a Ruby program while it executes.

It can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act:

  • Start your script, specifying anything that might affect its behavior.
  • Make your script stop on specified conditions.
  • Examine what has happened, when your script has stopped.
  • Change things in your script, so you can experiment with correcting the effects of one bug and go on to learn about another.
