Toy implementation of a "static façade" in Ruby. Based on the thread https://twitter.com/henrik/status/555450649652248577.

static_facade_example.rb

module StaticFacade
  def static_facade(*arg_names, name)
    arg_names.each { |x| attr_reader x; private x }

    define_method(:initialize) do |*arg_values|
      arg_names.zip(arg_values).each { |n, v| instance_variable_set("@#{n}", v) }
    end

    singleton_class.send(:define_method, name) do |*args|
      new(*args).send(name)
    end
  end
end

class Example
  extend StaticFacade

  static_facade :name,
  def yo
    puts greeting
  end

  private

  def greeting
    "Yo #{name}"
  end
end

Example.yo("mama")
