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: sanitize_ini_file.rb
    path of file: ./repos/hound/app/services
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
class SanitizeIniFile
  static_facade :call

  def initial
    
  def normalize_line(line)
    case line.rstrip
    when /.+=$/
      line.rstrip + " "
    when /^\s+.+,$/
      line.strip
    when /^\s+.+$/
      line.lstrip
    else
      line
    end
