Teaching Rails more languages is now as simple as:

• downloading example locales,
• putting them in your config/locales folder, and
• adding a method to ApplicationController that detects the user’s language:

class ApplicationController < ActionController::Base
  before_filter :set_locale
  def set_locale
    I18n.locale = request.env.fetch('HTTP_ACCEPT_LANGUAGE', '')[/(?:,|^)(de|en)\b/, 1]
  end
end

You have to adjust the regexp to allow automatic recognition of more languages; I haven’t found out yet how to get a list of all available locales without using I18n.load_path, but maybe the community helps me out.

It’s cool that changes to the locale files are applied instantly in development mode! A great improvement :D
