Class Method Details

.root ⇒ Object

Little big of magic to find the directory of the config.ru file, ie: the root directory for our application.

It looks through CALLER for a call originating from config.ru, extracts it’s relative path out and join it with Dir.getwd. This gives us the full path to config.ru and subsequently the root of our app.

If config.ru was not used, it raises an error.
