You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: overrider.rb
    path of file: ./repos/rails_amp/lib/rails_amp
    
    the code of the file until where you have to start completion: module RailsAmp
  module Overrider
    extend ActiveSupport::Concern

    included do
      before_action do
        RailsAmp.format = request[:format]
        if RailsAmp.amp_renderable?(controller_path, action_name)  # default_format is :amp
  
    
      def override_actions_with_rails_amp
        klass = self.class  # klass is controller class
        return if klass.ancestors.include?(RailsAmp::ActionOverrider)
        actions = RailsAmp.target_actions(klass)

        klass.class_eval do
          # override amp target actions
          RailsAmp::ActionOverrider.module_eval do
            actions.to_a.each do |action|
              define_method action.to_sym do
                super()
                unless performed?
                  respond_to do |format|
                    format.send(RailsAmp.default_format.to_sym) do
                      # search amp format(default is .amp) .html templates
                      lookup_context.formats = [RailsAmp.default_format] + RailsAmp.lookup_formats
                      render layout: 'rails_amp_application.amp'
                    end
                  end
                end
              end
            end
          end
          prepend RailsAmp::ActionOverrider
        end
