// ...
}
```
+
+### Step 3: Configure the Bundle
+
+Verify that you have the configuration file `config/packages/rapsys_pack.yaml`
+with the following content:
+
+```yaml
+#Services configuration
+services:
+ #Register assets pack package
+ assets.pack_package:
+ class: Rapsys\PackBundle\Asset\PathPackage
+ arguments: [ '/', '@assets.empty_version_strategy', '@assets.context' ]
+ #Register twig pack extension
+ rapsys_pack.twig.pack_extension:
+ class: Rapsys\PackBundle\Twig\PackExtension
+ arguments: [ '@file_locator', '@service_container', '@assets.pack_package' ]
+ tags: [ twig.extension ]
+```
+
+Open a command console, enter your project directory and execute the
+following command to see default bundle configuration:
+
+```console
+$ php bin/console config:dump-reference RapsysPackBundle
+```
+
+Open a command console, enter your project directory and execute the
+following command to see current bundle configuration:
+
+```console
+$ php bin/console debug:config RapsysPackBundle
+```
+
+### Step 4: Use the twig extension in your Template
+
+You can use a template like this to generate your first `rapsys_pack` enabled template:
+
+```twig
+<!DOCTYPE html>
+<html>
+ <head>
+ <meta charset="UTF-8" />
+ <title>{% block title %}Welcome!{% endblock %}</title>
+ {% stylesheet '//fonts.googleapis.com/css?family=Irish+Grover|La+Belle+Aurore' '@NamedBundle/Resources/public/css/{reset,screen}.css' '@Short/css/example.css' %}
+ <link rel="stylesheet" type="text/css" href="{{ asset_url }}" />
+ {% endstylesheet %}
+ </head>
+ <body>
+ {% block body %}{% endblock %}
+ {% javascript '@Short/js/*.js' %}
+ <script type="text/javascript" src="{{ asset_url }}"></script>
+ {% endjavascript %}
+ </body>
+</html>
+```
+
+### Step 5: Make sure you have local binary installed
+
+You need to have cpack and jpack scripts from https://git.rapsys.eu/packer/ repository
+set as executable and installed in /usr/local/bin.
+
+To install cpack and jpack required packages open a root console and execute the
+following command:
+
+```console
+# urpmi perl-base perl-CSS-Packer perl-JavaScript-Packer
+```
+
+or stone age distributions:
+
+```console
+# apt-get install libcss-packer-perl libjavascript-packer-perl
+```
+
+or other distributions through cpan:
+
+```console
+# cpan App::cpanminus
+# cpanm CSS::Packer
+# cpanm JavaScript::Packer
+```
+
+### Step 6: Create your own filter
+
+You can create you own mypackfilter class which call a mypack binary:
+
+```php
+<?php
+
+namespace Rapsys\PackBundle\Twig\Filter;
+
+use Rapsys\PackBundle\Twig\Filter\FilterInterface;
+use Twig\Error\Error;
+
+//This class will be defined in the parameter rapsys_pack.filters.(css|img|js).[x].class string
+class MyPackFilter implements FilterInterface {
+ //The constructor arguments ... will be replaced defined in the parameter rapsys_pack.filters.(css|img|js).[x].args array
+ public function __construct($fileName, $line, $bin = 'mypack', ...) {
+ //Set fileName
+ $this->fileName = $fileName;
+
+ //Set line
+ $this->line = $line;
+
+ //Set bin
+ $this->bin = $bin;
+
+ //Check argument presence
+ if (!empty($this->...)) {
+ //Append argument
+ if ($this->... == '...') {
+ $this->bin .= ' ...';
+ } else {
+ //Throw an error on ...
+ throw new Error(sprintf('Got ... for %s: %s', $this->bin, $this->...), $this->line, $this->fileName);
+ }
+ }
+ }
+
+ //Pass merge of all inputs in content
+ public function process($content) {
+ //Create descriptors
+ $descriptorSpec = array(
+ 0 => array('pipe', 'r'),
+ 1 => array('pipe', 'w'),
+ 2 => array('pipe', 'w')
+ );
+
+ //Open process
+ if (is_resource($proc = proc_open($this->bin, $descriptorSpec, $pipes))) {
+ //Set stderr as non blocking
+ stream_set_blocking($pipes[2], 0);
+
+ //Send content to stdin
+ fwrite($pipes[0], $content);
+
+ //Close stdin
+ fclose($pipes[0]);
+
+ //Read content from stdout
+ if ($stdout = stream_get_contents($pipes[1])) {
+ $content = $stdout;
+ }
+
+ //Close stdout
+ fclose($pipes[1]);
+
+ //Read content from stderr
+ if (($stderr = stream_get_contents($pipes[2]))) {
+ throw new Error(sprintf('Got unexpected strerr for %s: %s', $this->bin, $stderr), $this->line, $this->fileName);
+ }
+
+ //Close stderr
+ fclose($pipes[2]);
+
+ //Close process
+ if (($ret = proc_close($proc))) {
+ throw new Error(sprintf('Got unexpected non zero return code %s: %d', $this->bin, $ret), $this->line, $this->fileName);
+ }
+ }
+
+ //Return content
+ return $content;
+ }
+}
+```
+
+The class is required to get it's arguments through constructor and have a process method.
