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: base.rb
    path of file: ./repos/padrino-framework/padrino-core/lib/padrino-core/cli
    
    the code of the file until where you have to start completion: require 'padrino-core/cli/launcher'

module Padrino
  module Cli
    class Base < Launcher
      desc "rake", "Execute rake tasks."
      method_option :environment, :type => :string,  :aliases => "-e"
      method_option :list,        :type => :string,  :aliases => "-T", :desc => "Display the tasks (matching optional PATTERN) with descriptions, then exit."
      method_option :trace,       :type => :boolean, :aliases => "-t", :desc => "Turn on 
    
      def rake(*args)
        prepare :rake
        args << "-T" if options[:list]
        args << options[:list]  unless options[:list].nil? || options[:list].to_s == "list"
        args << "--trace" if options[:trace]
        args << "--verbose" if options[:verbose]
        ARGV.clear
        ARGV.concat(args)
        puts "=> Executing Rake #{ARGV.join(' ')} ..."
        load File.expand_path('rake.rb', __dir__)
        Rake.application.init
