Tomas Votruba has a post to his site sharing a method for translating Latte templates to Twig templates with the help of the Simplify tool.

Statie - a tool for generating static open-sourced website like this blog or Pehapkari.cz - runs on YAML and Symfony DI Container. That way it's easy to understand by the PHP community worldwide.

But there are some pitfalls left. Like templates - being Latte the only one is a pity. Twig is often requested feature and one of the last big reasons not to use Statie.

Well, it was. Statie will support both Twig and Latte since next version. Are you a Twig fan? As a side effect, I made 27 regular expression to handle 80 % of the Latte to Twig migration for you.

He starts with a bit of explanation of how to the project started and his goals ("investing 5 hours to automate 30-minutes manual work under 10 seconds, so no-one else will have to do that ever again"). He covers the installation of the Symplify tool and how to execute the latte-to-twig-converter on a directory of Latte templates. He also provides some snippets of code you can use if you want to reverse the process and go from Twig to Latte.
