decided to make some changes to allow for a single method to autoload external routing files

mapper.rb

# I've been meaning to send this too you... Remember the #draw method you pulled out of edge rails, well after using it in a personal 
# project (which by the way is awesome, totally digging it) I decided that I wanted to include more files in the one method, to reduce 
# the amount of times I wrote draw :something, so I modified it a little and thought you'd appreciate it... Cheers!

# In lib/mapper.rb

module ActionDispatch
  module Routing
    module Mapper
  
      def draw *route_names
        route_names.each do |route_name|
          instance_eval File.read(Rails.root.join("config/routes/#{route_name}.rb"))
        end
      end
  
    end
  end
end

# in routes.rb

Rails::Application.routes.draw do

  draw :api, :admin, :application
  
end
