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: client.rb
    path of file: ./repos/byebug/lib/byebug/remote
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require "socket"

module Byebug
  module Remote
    #
    # Client for remote debuggi
    
      def start(host = "localhost", port = PORT)
        connect_at(host, port)

        while (line = socket.gets)
          case line
          when /^PROMPT (.*)$/
            input = interface.read_command(Regexp.last_match[1])
            break unless input

            socket.puts input
          when /^CONFIRM (.*)$/
            input = interface.readline(Regexp.last_match[1])
            break unless input

            socket.puts input
          else
            interface.puts line
          end
