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: standalone.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/lib/bundler/installer
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Bundler
  class Standalone
    def initialize(groups, definition)
      @specs = definition.specs_for(groups)
    end

    def generate
      SharedHelpers.filesystem_access(bundler_path) do |p|
        FileUtils.mkdir_p
    
    def reverse_rubygems_kernel_mixin
      <<~END
      kernel = (class << ::Kernel; self; end)
      [kernel, ::Kernel].each do |k|
        if k.private_method_defined?(:gem_original_require)
          private_require = k.private_method_defined?(:require)
          k.send(:remove_method, :require)
          k.send(:define_method, :require, k.instance_method(:gem_original_require))
          k.send(:private, :require) if private_require
        end
      end
