+# Assetic [![Build Status](https://travis-ci.org/kriswallsmith/assetic.png?branch=master)](https://travis-ci.org/kriswallsmith/assetic) ![project status](http://stillmaintained.com/kriswallsmith/assetic.png) #
+
+Assetic is an asset management framework for PHP.
+
+``` php
+<?php
+
+use Assetic\Asset\AssetCollection;
+use Assetic\Asset\FileAsset;
+use Assetic\Asset\GlobAsset;
+
+$js = new AssetCollection(array(
+    new GlobAsset('/path/to/js/*'),
+    new FileAsset('/path/to/another.js'),
+));
+
+// the code is merged when the asset is dumped
+echo $js->dump();
+```
+
+Assets
+------
+
+An Assetic asset is something with filterable content that can be loaded and
+dumped. An asset also includes metadata, some of which can be manipulated and
+some of which is immutable.
+
+| **Property** | **Accessor**    | **Mutator**   |
+|--------------|-----------------|---------------|
+| content      | getContent      | setContent    |
+| mtime        | getLastModified | n/a           |
+| source root  | getSourceRoot   | n/a           |
+| source path  | getSourcePath   | n/a           |
+| target path  | getTargetPath   | setTargetPath |
+
+The "target path" property denotes where an asset (or an collection of assets) should be dumped.
+
+Filters
+-------
+
+Filters can be applied to manipulate assets.
+
+``` php
+<?php
+
+use Assetic\Asset\AssetCollection;
+use Assetic\Asset\FileAsset;
+use Assetic\Asset\GlobAsset;
+use Assetic\Filter\LessFilter;
+use Assetic\Filter\Yui;
+
+$css = new AssetCollection(array(
+    new FileAsset('/path/to/src/styles.less', array(new LessFilter())),
+    new GlobAsset('/path/to/css/*'),
+), array(
+    new Yui\CssCompressorFilter('/path/to/yuicompressor.jar'),
+));
+
+// this will echo CSS compiled by LESS and compressed by YUI
+echo $css->dump();
+```
+
+The filters applied to the collection will cascade to each asset leaf if you
+iterate over it.
+
+``` php
+<?php
+
+foreach ($css as $leaf) {
+    // each leaf is compressed by YUI
+    echo $leaf->dump();
+}
+```
+

+
+ * `AutoprefixerFilter`: Parse and update vendor-specific properties using autoprefixer
+ * `CoffeeScriptFilter`: compiles CoffeeScript into Javascript
+ * `CompassFilter`: Compass CSS authoring framework

+ * `GssFilter`: compliles CSS using the Google Closure Stylesheets Compiler

+
+Asset Manager
+-------------
+
+An asset manager is provided for organizing assets.
+
+``` php
+<?php
+
+use Assetic\AssetManager;
+use Assetic\Asset\FileAsset;
+use Assetic\Asset\GlobAsset;
+
+$am = new AssetManager();
+$am->set('jquery', new FileAsset('/path/to/jquery.js'));
+$am->set('base_css', new GlobAsset('/path/to/css/*'));
+```
+
+The asset manager can also be used to reference assets to avoid duplication.
+
+``` php
+<?php
+
+use Assetic\Asset\AssetCollection;
+use Assetic\Asset\AssetReference;
+use Assetic\Asset\FileAsset;
+
+$am->set('my_plugin', new AssetCollection(array(
+    new AssetReference($am, 'jquery'),
+    new FileAsset('/path/to/jquery.plugin.js'),
+)));
+```
+
+Filter Manager
+--------------
+
+A filter manager is also provided for organizing filters.
+
+``` php
+<?php
+
+use Assetic\FilterManager;
+use Assetic\Filter\Sass\SassFilter;
+use Assetic\Filter\Yui;
+
+$fm = new FilterManager();
+$fm->set('sass', new SassFilter('/path/to/parser/sass'));
+$fm->set('yui_css', new Yui\CssCompressorFilter('/path/to/yuicompressor.jar'));
+```
+
+Asset Factory
+-------------
+
+If you'd rather not create all these objects by hand, you can use the asset
+factory, which will do most of the work for you.
+
+``` php
+<?php
+
+use Assetic\Factory\AssetFactory;
+
+$factory = new AssetFactory('/path/to/asset/directory/');
+$factory->setAssetManager($am);
+$factory->setFilterManager($fm);
+$factory->setDebug(true);
+
+$css = $factory->createAsset(array(
+    '@reset',         // load the asset manager's "reset" asset
+    'css/src/*.scss', // load every scss files from "/path/to/asset/directory/css/src/"
+), array(
+    'scss',           // filter through the filter manager's "scss" filter
+    '?yui_css',       // don't use this filter in debug mode
+));
+
+echo $css->dump();
+```
+
+The `AssetFactory` is constructed with a root directory which is used as the base directory for relative asset paths.
+
+Prefixing a filter name with a question mark, as `yui_css` is here, will cause
+that filter to be omitted when the factory is in debug mode.
+
+You can also register [Workers](src/Assetic/Factory/Worker/WorkerInterface.php) on the factory and all assets created
+by it will be passed to the worker's `process()` method before being returned. See _Cache Busting_ below for an example.
+
+Dumping Assets to static files
+------------------------------
+
+You can dump all the assets an AssetManager holds to files in a directory. This will probably be below your webserver's document root
+so the files can be served statically.
+
+``` php
+<?php
+
+use Assetic\AssetWriter;
+
+$writer = new AssetWriter('/path/to/web');
+$writer->writeManagerAssets($am);
+```
+
+This will make use of the assets' target path.
+
+Cache Busting
+-------------
+
+If you serve your assets from static files as just described, you can use the CacheBustingWorker to rewrite the target
+paths for assets. It will insert an identifier before the filename extension that is unique for a particular version
+of the asset.
+
+This identifier is based on the modification time of the asset and will also take depended-on assets into
+consideration if the applied filters support it.
+
+``` php
+<?php
+
+use Assetic\Factory\AssetFactory;
+use Assetic\Factory\Worker\CacheBustingWorker;
+
+$factory = new AssetFactory('/path/to/asset/directory/');
+$factory->setAssetManager($am);
+$factory->setFilterManager($fm);
+$factory->setDebug(true);
+$factory->addWorker(new CacheBustingWorker());
+
+$css = $factory->createAsset(array(
+    '@reset',         // load the asset manager's "reset" asset
+    'css/src/*.scss', // load every scss files from "/path/to/asset/directory/css/src/"
+), array(
+    'scss',           // filter through the filter manager's "scss" filter
+    '?yui_css',       // don't use this filter in debug mode
+));
+
+echo $css->dump();
+```
+
+Internal caching
+-------
+
+A simple caching mechanism is provided to avoid unnecessary work.
+
+``` php
+<?php
+
+use Assetic\Asset\AssetCache;
+use Assetic\Asset\FileAsset;
+use Assetic\Cache\FilesystemCache;
+use Assetic\Filter\Yui;
+
+$yui = new Yui\JsCompressorFilter('/path/to/yuicompressor.jar');
+$js = new AssetCache(
+    new FileAsset('/path/to/some.js', array($yui)),
+    new FilesystemCache('/path/to/cache')
+);
+
+// the YUI compressor will only run on the first call
+$js->dump();
+$js->dump();
+$js->dump();
+```
+
+Twig
+----
+
+To use the Assetic [Twig][3] extension you must register it to your Twig
+environment:
+
+``` php
+<?php
+
+$twig->addExtension(new AsseticExtension($factory));
+```
+
+Once in place, the extension exposes a stylesheets and a javascripts tag with a syntax similar
+to what the asset factory uses:
+
+``` html+jinja
+{% stylesheets '/path/to/sass/main.sass' filter='sass,?yui_css' output='css/all.css' %}
+    <link href="{{ asset_url }}" type="text/css" rel="stylesheet" />
+{% endstylesheets %}
+```
+
+This example will render one `link` element on the page that includes a URL
+where the filtered asset can be found.
+
+When the extension is in debug mode, this same tag will render multiple `link`
+elements, one for each asset referenced by the `css/src/*.sass` glob. The
+specified filters will still be applied, unless they are marked as optional
+using the `?` prefix.
+
+This behavior can also be triggered by setting a `debug` attribute on the tag:
+
+``` html+jinja
+{% stylesheets 'css/*' debug=true %} ... {% stylesheets %}
+```
+
+These assets need to be written to the web directory so these URLs don't
+return 404 errors.
+
+``` php
+<?php
+
+use Assetic\AssetWriter;
+use Assetic\Extension\Twig\TwigFormulaLoader;
+use Assetic\Extension\Twig\TwigResource;
+use Assetic\Factory\LazyAssetManager;
+
+$am = new LazyAssetManager($factory);
+
+// enable loading assets from twig templates
+$am->setLoader('twig', new TwigFormulaLoader($twig));
+
+// loop through all your templates
+foreach ($templates as $template) {
+    $resource = new TwigResource($twigLoader, $template);
+    $am->addResource($resource, 'twig');
+}
+
+$writer = new AssetWriter('/path/to/web');
+$writer->writeManagerAssets($am);
+```

+Assetic is based on the Python [webassets][1] library (available on
+[GitHub][2]).
