Trace the code in Ruby? [closed]

Question

Is there a good way to run a script and see all the steps:

• Which code is executed
• Which file the code is in
• What it returns
• The error messages

This would be a good way to learn how an open source project is working.

Aren't there solutions like this for Ruby?

Eg.

require "httparty"
HTTParty.get "http://www.google.se"

Then it would run the code and show me all the code it is executing, in which file and line, returned objects, error messages etc.

Tracer might do it for you http://en.wikibooks.org/wiki/Ruby_Programming/Standard_Library/Tracer

if you want to just see exceptions raised, then run ruby -d (or use ruby-debug and "Catch" Exception)
