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: config.rb
    path of file: ./repos/procodile/lib/procodile
    
    the code of the file until where you have to start completion: require 'yaml'
require 'fileutils'
require 'procodile/error'
require 'procodile/process'

module Procodile
  class Config

    COLORS = [35, 31, 36, 32, 33, 34]

    def initialize(root, procfile = nil)
      @root = root
      @procfile_path = procfile

      unless File.file
    
    def reload
      @process_list = nil
      @options = nil
      @process_options = nil
      @local_options = nil
      @local_process_options = nil
      @loaded_at = nil
      @environment_variables = nil

      if @processes
        process_list.each do |name, command|
          if process = @processes[name]
            process.removed = false
            # This command is already in our list. Add it.
            if process.command != command
              process.command = command
              Procodile.log nil, 'system', "#{name} command has changed. Updated."
            end
            process.options = options_for_process(name)
          else
            Procodile.log nil, 'system', "#{name} has been added to the Procfile. Adding it."
