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: task_manager.rb
    path of file: ./repos/truffleruby/lib/gems/gems/rake-13.0.6/lib/rake
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
module Rake

  # The TaskManager module is a mixin for managing tasks.
  module TaskManager
    # Track the last comment made in the Rakefile.
    attr_accessor :last_description

    def initialize # :nodoc:
      super
      @tasks = Hash.new
      @rules = Array.new
      @scope = Scope.make
      @last_description = nil
    end

    def create_rule(*args, &block) # :nodoc:
      patte
    
    def generate_did_you_mean_suggestions(task_name)
      return "" unless defined?(::DidYouMean::SpellChecker)

      suggestions = ::DidYouMean::SpellChecker.new(dictionary: @tasks.keys).correct(task_name.to_s)
      if ::DidYouMean.respond_to?(:formatter)# did_you_mean v1.2.0 or later
        ::DidYouMean.formatter.message_for(suggestions)
      elsif defined?(::DidYouMean::Formatter) # before did_you_mean v1.2.0
        ::DidYouMean::Formatter.new(suggestions).to_s
      else
