Drop in Single Breakpoint in Ruby Code

Question

I am trying to find ruby code that has commensurate functionality to these lines in python:

import code
code.interact(local=locals())

These lines essentially insert a single breakpoint into my code and open up a console where I can interact with any variables.

Any thoughts on how to do this in Ruby?

For those that know Ruby but not Python, please explain what those lines do. — Phrogz, Dec 01 '11 at 20:16
You should describe this code in plain english, in case we don't speak python — Damien, Dec 01 '11 at 20:17

You want the Pry library:

require 'pry' # gem install pry
binding.pry   # Drop into the pry console

There is Kernel#local_variables in Ruby that returns the names of the current local variables. Check out the docs:

ri local_variables
