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: mdl.rb
    path of file: ./repos/markdownlint/lib
    
    the code of the file until where you have to start completion: require_relative 'mdl/formatters/sarif'
require_relative 'mdl/cli'
require_relative 'mdl/config'
require_relative 'mdl/doc'
require_relative 'mdl/kramdown_parser'
require_relative 'mdl/ruleset'
require_relative 'mdl/style'
require_
    
  def self.run(argv = ARGV)
    cli = MarkdownLint::CLI.new
    cli.run(argv)
    ruleset = RuleSet.new
    ruleset.load_default unless Config[:skip_default_ruleset]
    Config[:rulesets]&.each do |r|
      ruleset.load(r)
    end
    rules = ruleset.rules
    Style.load(Config[:style], rules)
    # Rule option filter
    if Config[:rules]
      unless Config[:rules][:include].empty?
        rules.select! do |r, v|
          Config[:rules][:include].include?(r) or
            !(Config[:rules][:include] & v.aliases).empty?
        end
      end
