# Fav

# Recursive Module Includes - yaml_dot_notation.rb

# This is an attempt to try to create a Hashie like dot notation 
# for accessing nested elements within a yaml file. 
# This seems a little "clever" but for certain uses, 
# like tranversing a single branch of a very large yaml, 
# it might prove more effective than other methods.

yaml_dot_notation.rb

require 'yaml'

module Dot
  def method_missing(method_name, *args, &block)
    if result = self[method_name.to_s]
      [result].flatten.each do |r|
        class << r
          include Dot
        end
      end
      result
    else
      super
    end
  end
end

class Parser
  attr_accessor :path, :doc
  
  def initialize(path)
    @path = path
  end
  
  def parse
    doc = YAML::load(File.read(path))
    class << doc
      include Dot
    end
    doc
  end  
end

### TESTS

require 'test/unit'

class ParsingTest < Test::Unit::TestCase
  
  def setup
    @data = Parser.new('music.yaml').parse
  end
  
  def test_bracket_interface
    assert @data["genres"].last["artists"].first["albums"].first["tracks"].last["name"] == "But Not For Me"
  end
  
  def test_dot_interface
    assert @data.genres.last.artists.first.albums.first.tracks.last.name == "But Not For Me"
  end
  
end
