There is a ruby-debugger gem which is very handy for trouble shooting problems in a ruby script. The built in debugging is quite powerful and worth learning to use.

First off, install ruby-debug:

# If using ruby1.8
$ gem install ruby-debug

# If using ruby 1.9.1
$ gem install ruby-debug19

Next: Watch this video….

The big thing to remember is help is your friend.

Finally: A handy ~/.rdebugrc file:

# rdebugrc
set autolist   on
set autoeval   on
set autoreload on
# EOF

Ciao!
