This object is an extended hash that behaves as root of the Rails::Paths system. It allows you to collect information about how you want to structure your application paths through a Hash-like API. It requires you to give a physical path on initialization.

root = Root.new "/rails"
root.add "app/controllers", eager_load: true

The above command creates a new root object and adds “app/controllers” as a path. This means we can get a Rails::Paths::Path object back like below:

path = root["app/controllers"]
path.eager_load?               # => true
path.is_a?(Rails::Paths::Path) # => true

The Path object is simply an enumerable and allows you to easily add extra paths:

path.is_a?(Enumerable) # => true
path.to_ary.inspect    # => ["app/controllers"]

path << "lib/controllers"
path.to_ary.inspect    # => ["app/controllers", "lib/controllers"]

Notice that when you add a path using add, the path object created already contains the path with the same path value given to add. In some situations, you may not want this behavior, so you can give :with as option.

root.add "config/routes", with: "config/routes.rb"
root["config/routes"].inspect # => ["config/routes.rb"]

The add method accepts the following options as arguments: eager_load, autoload, autoload_once, and glob.

Finally, the Path object also provides a few helpers:

root = Root.new "/rails"
root.add "app/controllers"

root["app/controllers"].expanded # => ["/rails/app/controllers"]
root["app/controllers"].existent # => ["/rails/app/controllers"]

Check the Rails::Paths::Path documentation for more information.
