See RDoc for Readline module.

Add this line to your application's Gemfile:

gem 'readline'

And then execute:

$ bundle

Or install it yourself as:

$ gem install readline

require "readline"
while buf = Readline.readline("> ", true)
  p buf
end

require "readline"
while buf = Readline.readline("> ", true)
  p Readline::HISTORY.to_a
  print("-> ", buf, "\n")
end

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.
