debugger-pry

This gem adds a pry command to the debugger gem enabling you to bring up a pry console during your session. It is similar to debugger's built-in irb command.

To see it in action, run ruby examples/foo.rb and type "pry" at the debug prompt.

To use it in a project, add this to your Gemfile:

gem "debugger-pry", :require => "debugger/pry"
