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: application_controller.rb
    path of file: ./repos/brakeman/test/apps/rails2/app/controllers
    
    the code of the file until where you have to start completion: # Filters added to this controller apply to all controllers in the application.
# Likewise, all the methods added will be available for all controllers.

class ApplicationController < ActionController::Base
  helper :all # include all he
    
  def awesome
    something = if params[:thang]
                  params[:thang]
                elsif somevar = "monkeypanda"
                  somevar = somevar.split(",").map { |s|
                    s += 'stuff' unless s =~ /regex/
                      s.split('things')
                  }.first
                  somevar.first.downcase
                end
