This library provides debugging functionality to Ruby.

Add this line to your application's Gemfile:

gem 'debug'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install debug

To add a debugger to your code, start by requiring +debug+ in your program:

def say(word)
  require 'debug'
  puts word
end

This will cause Ruby to interrupt execution and show a prompt when the +say+ method is run.

Once you're inside the prompt, you can start debugging your program.

(rdb:1) p word
"hello"

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
