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

Ruby-debug 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.
