Direction

Enforce better encapsulation by returning self from commands.

Thanks to James Ladd for the inspiration.

Usage

Provide a feature like the Forwardable library, but set the return value to self.

It provides a class level "command" method to do message forwarding.

class SomeClass
  extend Direction

  command [:name, :id] => :collaborator, [:color, :type] => :partner
end

This will define methods on instances that forward to the provided receiver while enforcing encapsulation of the relationship between objects.

Add this line to your application's Gemfile:

gem 'direction'

And then execute:

$ bundle

Or install it yourself as:

$ gem install direction
