How to render a partial using HamlPHP

hamlphp.render_partial.php

<?php

// WARNING: This is the simplest possible example. It could be vastly improved
// by keeping the HamlPHP instance somewhere and, even more important, caching parser results

function render_partial($file, $data) {
  $parser = new HamlPHP(new FileStorage('path/to/tmp/'));
  $content = $parser->parseFile($file);
  echo $parser->evaluateFile($content, $data);
}
