Jade is originally a template engine for NodeJS, now available for PHP also. Jade.php is a high performance template compiler heavily influenced by Haml and implemented for PHP 5.3.
Key features include :
- high performance parser
- great readability
- contextual error reporting at compile & run time
- html 5 mode (using the !!! 5 doctype)
- combine dynamic and static tag classes
- no tag prefix
- clear & beautiful HTML output
Jade.php got already extension for TextMate, VIM and Symfony2. I guess Symfony users will be very familiar with the YAML-inspired templates engine more than anybody else.
