This gem is a try at writing a simple Ruby debugger detailed on my blog http://akash.im/2012/05/12/home-made-debugger-in-ruby.html
gem install take-a-look
When you want to debug some program, just drop the following line in the place you want to inspect.
That will start a REPL in which you can play with the constants and values of variables set in the program.
If you feel that it's a lengthy method name,
- It's all less than 10 lines + a test case.
- This gem was written in 13 minutes (not that I'm proud of it).
