• cache: An absolute path where to store the compiled templates, or false to disable compilation cache (default).

• autoescape: Whether to enable auto-escaping (default to html):
  • false: disable auto-escaping
  • true: equivalent to html
  • html, js: set the autoescaping to one of the supported strategies
  • PHP callback: a PHP callback that returns an escaping strategy based on the template "filename"
