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: attribute_parser.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/haml-5.0.1/lib/haml
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
begin
  require 'ripper'
rescue Load
    
      def parse(exp)
        return nil unless hash_literal?(exp)

        hash = {}
        each_attribute(exp) do |key, value|
          hash[key] = value
        end
        hash
      rescue UnexpectedTokenError, UnexpectedKeyError
        nil
      end
