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: generator.rb
    path of file: ./repos/sord/lib/sord
    
    the code of the file until where you have to start completion: # typed: true
require 'yard'
require 'sord/type_converter'
require 'sord/l
    
    def add_attributes(item)
      [:class, :instance].each do |attr_loc|
        # Grab attributes for the current location (class or instance)
        attrs = item.attributes[attr_loc]
        attrs.each do |name, attribute|
          reader = attribute[:read]
          writer = attribute[:write]

          unless reader || writer
            Logging.warn("attribute is not readable or writable somehow, skipping", attribute)
            next
          end

          # Get all given types
          yard_types = []
          if reader
            next if @hide_private && reader.visibility == :private
            yard_types += reader.tags('return').flat_map(&:types).compact.reject { |x| x.downcase == 'void' } +
              reader.tags('param').flat_map(&:types)
          end
          if writer
            next if @hide_private && writer.visibility == :private
            yard_types += writer.tags('return').flat_map(&:types).compact.reject { |x| x.downcase == 'void' } +
              writer.tags('param').flat_map(&:types)
          end
