This Bundle initializes Less.js into Symfony2 Framework

===================

Setup:

app/AppKernel.php:

Warning!

Namespace changed from Less\CssBundle\LessCssBundle to Skillberto\LessCssBundle\SkillbertoLessCssBundle.

This declaration is deprecated: new Less\CssBundle\LessCssBundle() Correct:

...
new Skillberto\LessCssBundle\SkillbertoLessCssBundle(),
...

Run in console:

assets:install
assetic:dump

Use the less css JavaScript:

<script src="{{ asset('bundles/lesscss/js/less-1.3.3.min.js') }}"></script>

OR (from bundle)

{% javascripts
    '@LessCssBundle/Resources/public/js/*'
 %}
    <script src="{{ asset_url }}"></script>
{% endjavascripts %}

With this mode, you can include your .less, eg: style.less 'css':

<link rel="stylesheet/less" href="{{ asset('YOURBUNDLE/css/style.less') }}" />

But this mode is not secure. Better way is to copy into web/css/ and include from this folder, or use this other way.

Other way: Assetic filter method

For this, you have to use Node, or some kind of PHP or other script.

With Node:

#...
assetic:
    filters:
        cssrewrite: ~
        less:
            node: /usr/local/bin/node
            node_paths: [/usr/local/lib/node_modules]
            apply_to: "\.less$"
...

With PHP:

For example,a good way is the leafo/lessphp:

Put into composer.json:

...
"require": {
    ...
    "leafo/lessphp": "0.3.*@dev"
}
...

Update composer, and put into app/config/config.yml:

#...
assetic:
    #...
    filters:
        lessphp:
            file: %kernel.root_dir%/../vendor/leafo/lessphp/lessc.inc.php
            apply_to: "\.less$"

Now, you can use from the hood with assetic filter:

{% stylesheets 'path/to/files.less' %}
  <link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %} 

Run in console:

assets:install
assetic:dump

The public data will be in web directory, and .less compiled to .css
