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: sprue_file.rb
    path of file: ./repos/squib/lib/squib/args
    
    the code of the file until where you have to start completion: require_relative 'arg_loader'

module Squib::Args
  module_function def extract_sprue_file(opts, deck, dsl_method_default = {})
    SprueFile.new.extract! opts, deck
  end
  class SprueFile
    include ArgLoader

    def initialize(dsl_method_default = {})

    
    def validate_template_file(arg)
      return nil if arg.nil?

      thefile = File.exist?(arg) ? arg : builtin(arg)
      raise "File #{File.expand_path(arg)} does not exist!" unless
        File.exist? thefile

      File.expand_path(thefile)
    end

    private

    def builtin(file)
      "#{File.dirname(__FILE__)}/../builtin/sprues/#{file}"
    end
  end
