Here you go:

lib/user_name_suggester.rb

bb0fa5abb

module UserNameSuggester
  GENERIC_NAMES = ['i', 'me', 'info', 'support', 'admin', 'webmaster', 'hello', 'mail', 'office', 'contact', 'team']

  def self.suggest(name, allow_username = nil)
    return unless name.present?
    name = parse_name_from_email(name)
    find_available_username_based_on(name, allow_username)
  end

  def self.parse_name_from_email(name)
    if name =~ User::EMAIL
      # When 'walter@white.com' take 'walter'
      name = Regexp.last_match[1]
      # When 'me@eviltrout.com' take 'eviltrout'
      name = Regexp.last_match[2] if GENERIC_NAMES.include?(name)
    end
    name
  end

  def self.find_available_username_based_on(name, allow_username = nil)
