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: metadata.rb
    path of file: ./repos/discourse/lib/plugin
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

# loaded really early
module Plugin
end

class Plugin::Metadata
  OFFICIAL_PLUGINS ||=
    Set.new(
      %w[
        discourse-adplugin
        discourse-affiliate
        discourse-ai
        discourse-akismet
   
    
  def parse_line(line)
    line = line.strip

    unless line.empty?
      return false unless line[0] == "#"
      attribute, *value = line[1..-1].split(":")

      value = value.join(":")
      attribute = attribute.strip.gsub(/ /, "_").to_sym

      if FIELDS.include?(attribute)
        self.public_send(
          "#{attribute}=",
          value.strip.truncate(MAX_FIELD_LENGTHS[attribute] || 1000),
        )
      end
