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: xnu_source.rb
    path of file: ./repos/apple-knowledge/lib
    
    the code of the file until where you have to start completion: # frozen_string_literal
    
  def each_source_file
    Dir.glob(File.join(@path, '**', '*')).each do |entry|
      next if File.directory? entry
      next unless SUPPORTED_FILE_EXTENSIONS.include? File.extname(entry).delete_prefix('.')

      yield entry.delete_prefix(@path), File.read(entry)
    rescue StandardError => e
      puts "Error in processing file #{entry}.  Inner error:\n\n#{e}"
    end
  end
