How to use

PHP wrapper for the Google Closure JS Compiler web service.

Handles caching and recompilation of sources. A recompilation will occur whenever a source file, or the script calling the compiler, changes.

The class will handle the Last-Modified and 304 redirects for you, but if you should set Cache-Control headers appropriate for your needs.

Make sure you define LIB_DIR, then place the jar files and soyutils.js under LIB_DIR/third-party/.

Example usage:

define('LIB_DIR', getcwd() . 'lib/');

include(LIB_DIR . 'third-party/php-closure.php');

$c = new PhpClosure();
$c->add('my-app.js')
  ->addDir('/js/') // new
  ->add('popup.js')
  ->add('popup.soy') // new
  ->advancedMode()
  ->cacheDir('/tmp/js-cache/')
  ->localCompile() // new
  ->write();

See http://code.google.com/closure/compiler/docs/api-ref.html for more details on the compiler options.
