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: plist.rb
    path of file: ./repos/puppet/lib/puppet/util
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'cfpropertylist' if Puppet.features.cfpropertylist?
require_relative '../../puppet/util/execution'

module Puppet::Util::Plist
  cla
    
    def read_plist_file(file_path)
      # We can't really read the file until we know the source encoding in
      # Ruby 1.9.x, so we use the magic number to detect it.
      # NOTE: We used IO.read originally to be Ruby 1.8.x compatible.
      if read_file_with_offset(file_path, binary_plist_magic_number.length) == binary_plist_magic_number

        plist = parse_plist(plist_data, file_path)
