Timeout provides a way to auto-terminate a potentially long-running operation if it hasn't finished in a fixed amount of time.

Add this line to your application's Gemfile:

gem 'timeout'

And then execute:

$ bundle

Or install it yourself as:

$ gem install timeout

require 'timeout'
status = Timeout.timeout(5) {
  # Something that should be interrupted if it takes more than 5 seconds...
}

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.
