This code uses Sinatra to display a very simple web page within the Locker UI. Mostly, this is a demonstration of how to put the ruby process lifetime at the mercy of the lockerd service loader, and how to launch sinatra based on the launch requirements of lockerd.
There is a slight change to sinatra neccessary to have it return the data neededon successful launch; because of this the project currently uses Bundler to point at Sinatra HEAD on GitHub. Sinatra 1.3.0 should include the neccessary changes.
If you are unfamiliar with Bundler, simply:
$ gem install bundler $ cd <path/to/HelloRuby> $ bundle install
