smurfy/SmurfyAsseticCssBundleImagesBundle

Repository files navigation

Provides a new Assetic filter for CSS files which allows you the "@MyBundle" syntax in your CSS. It also exposes DI Container parameters to the CSS File

Example 1 - Using the @MyBundle syntax:

background: url(@MyBundle/Resources/public/images/backgrounds.png);

Example 2 - Using the DI Container syntax:

background: url(%kernel.root_dir%/../vendor/twitter/bootstrap/img/sprite-map.png);

Example 3 - You even can combine both:

background: url(@MyBundle/Resources/public/images/%site.mood%/backgrounds.png);

It also converts all images to assets and allows you to use an existing asset filter for it (like optipng for pngs)

Installation

Symfony 2.1.x

Add the require line to composer.json

"require": {
    ....
    "smurfy/asseticcssbundleimages-bundle": "dev-master"
    ...
}

and update composer::

php composer.phar update

Add SmurfyAsseticCssBundleImagesBundle to your application kernel

// app/AppKernel.php

public function registerBundles()
{
    return array(
        new Symfony\Bundle\SecurityBundle\SecurityBundle(),
        // ...
        new Smurfy\AsseticCssBundleImagesBundle\SmurfyAsseticCssBundleImagesBundle(),
        // ...
    );
}

Symfony 2.0.x

Add SmurfyAsseticCssBundleImagesBundle to your vendor/bundles/ dir

Add the following lines in your deps file::

[SmurfyAsseticCssBundleImagesBundle]
    git=git://github.com/smurfy/SmurfyAsseticCssBundleImagesBundle.git
    target=bundles/Smurfy/AsseticCssBundleImagesBundle

Run the vendors script::

./bin/vendors install

Add the Smurfy namespace to your autoloader

// app/autoload.php
$loader->registerNamespaces(array(
    'Smurfy' => __DIR__.'/../vendor/bundles',
    // your other namespaces
);

Add SmurfyAsseticCssBundleImagesBundle to your application kernel

// app/AppKernel.php

public function registerBundles()
{
    return array(
        new Symfony\Bundle\SecurityBundle\SecurityBundle(),
        // ...
        new Smurfy\AsseticCssBundleImagesBundle\SmurfyAsseticCssBundleImagesBundle(),
        // ...
    );
}

Configuration

By default the filter outputs all files to /assetic/ but you can change that, also you can specify which filter should be used by extention.

smurfy_assetic_css_bundle_images:
    output: assetic/*
    absolute: true
    lessUrlRewriteWorkaround: false
    filters:
        png:
            - optipng
        jpg:
            - jpegoptim

Sample Usage

In your twig template enable the filter

{% stylesheets
    '@MyBundle/Resources/public/css/*' filter='cssbundleimages' output='assetic/*.css'
%}
    <link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}

After that you can use inside your css file something like that:

.body {
    background: url(@MyBundle/Resources/public/images/backgrounds.png);
}

LESS Support

Less is fully supported. Just make sure you load the less filter before the cssbundleimages filter.

Be aware, that less does url rewrites of "url" tags if you import other less files in subdirectories and the url tag uses relative aka not beginning with / urls. After that the cssbundleimages filter does no longer work, because the url not longer begins with @BundleName but with subdirectory/@BundleName. There is the lessUrlRewriteWorkaround config parameter which allows you to use /@BundleName.

.body {
    background: url(/@MyBundle/Resources/public/images/backgrounds.png);
}

This way less does no url rewrites, because it detects the url as absolute.

Final Notes

Assetic Controller support is working but it always rescans all css files which of course is not so fast. It is recommended to use assetic:watch (assetic:dump --watch on old versions of assetic bundle) For my Project its ok but it could be a bottleneck in a large development environment.
