Will be adding all my changes to https://github.com/cyonite/phade/ ended up converting a lot of stuff from original jade project. Nothing will really remain. You can see test results on http://phade.io/
Jade.php adds inline PHP scripting support to the Jade template compiler.
The fork is a complete rewrite, all the code is ported from the original jade project.
All the features from the original are supported but undertested, including inheritance and mixins.
