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: server.rb
    path of file: ./repos/hyperstack/ruby/hyperstack-config/lib/hyperstack/hotloader
    
    the code of the file until where you have to start completion: require 'websocket'
require 'socket'
require 'fiber'
require 'listen'
require 'optparse'
require 'json'

module Hyperstack
  class Hotloader
    # Most of this lifted from https://github.com/saward/Rubame
    
    
      def initialize(options)
        Socket.do_not_reverse_lookup
        @hostname = '0.0.0.0'
        @port = options[:port]
        setup_directories(options)

        @reading = []
        @writing = []

        @clients = {} # Socket as key, and Client as value

        @socket = TCPServer.new(@hostname, @port)
        @reading.push @socket
      end
