title: How to use SCSS filter in Symfony2 under Windows?
body: <p>Actually, this is two questions: </p>
  
  <ol>
  <li><p>What is the correct way to use the SCSS filter in my Symfony project in Windows (in Twig templates) ?
  I mean, how do i use the scss binary in windows?</p></li>
  <li><p>Also, Do I necessarily need to use Compass? and "HOW" do i use compass if I have installed it?</p></li>
  </ol>
  
  <p><strong>Extension</strong> : Here is some configuration I have done:</p>
  
  <p>In <em>app/config/config.yml</em></p>
  
  <pre class="lang-perl prettyprint-override"><code>assetic:
  debug:          %kernel.debug%
  use_controller: false
  filters:
      scss:
          bin: "%kernel.root_dir%/Resources/libs/scss"
      compass:
          bin: "%kernel.root_dir%/Resources/libs/compass" 
  </code></pre>
  
  <hr>
  
  <p>In my twig file:</p>
  
  <pre class="lang-html prettyprint-override"><code>{% stylesheets 
        '@PlaylyfeBaseBundle/Resources/public/css/base.scss'
        '@PlaylyfeBaseBundle/Resources/public/css/another.scss'
     filter='scss'
     output='css/compiled/total.css'
  %}
  &lt;link rel="stylesheet" href="{{ asset_url }}" /&gt;
  {% endstylesheets %}
  </code></pre>
  
  <hr>
  
  <p>But, when i load the page, I get the following error (inside the css file)</p>
  
  <pre class="lang-js prettyprint-override"><code>[exception] 500 | Internal Server Error | RuntimeException
  [message] The filename, directory name, or volume label syntax is incorrect.
  
  [1] RuntimeException: The filename, directory name, or volume label syntax is incorrect.
