Installation

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



Applications that use Symfony Flex

----------------------------------



Add bundle custom repository to your project's `composer.json` file:



```json

{

	...,

	"repositories": [

		{

			"type": "package",

			"package": {

				"name": "rapsys/packbundle",

				"version": "dev-master",

				"source": {

					"type": "git",

					"url": "https://git.rapsys.eu/packbundle",

					"reference": "master"

				},

				"autoload": {

					"psr-4": {

						"Rapsys\\PackBundle\\": ""

					}

				},

				"require": {

					"symfony/asset": "^4.0|^5.0|^6.0|^7.0",

					"symfony/flex": "^1.0|^2.0",

					"symfony/framework-bundle": "^4.0|^5.0|^6.0|^7.0",

					"symfony/process": "^4.0|^5.0|^6.0|^7.0",

					"symfony/twig-bundle": "^4.0|^5.0|^6.0|^7.0"

				}

			}

		}

	],

	...

}

```



Then open a command console, enter your project directory and execute:



```console

$ composer require rapsys/packbundle dev-master

```



Applications that don't use Symfony Flex

----------------------------------------



### Step 1: Download the Bundle



Open a command console, enter your project directory and execute the

following command to download the latest stable version of this bundle:



```console

$ composer require rapsys/packbundle dev-master

```



This command requires you to have Composer installed globally, as explained

in the [installation chapter](https://getcomposer.org/doc/00-intro.md)

of the Composer documentation.



### Step 2: Enable the Bundle



Then, enable the bundle by adding it to the list of registered bundles

in the `app/AppKernel.php` file of your project:



```php



	

		

		{% block title %}Welcome!{% endblock %}

		{% stylesheet '//fonts.googleapis.com/css?family=Irish+Grover|La+Belle+Aurore' '@NamedBundle/Resources/public/css/{reset,screen}.css' '@Short/css/example.css' %}

			

		{% endstylesheet %}

	

	

		{% block body %}{% endblock %}

		{% javascript '@Short/js/*.js' %}

			

		{% endjavascript %}

	



```



### 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

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(string $content): string {

		//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], false);



			//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 must implements FilterInterface and get it's arguments through constructor.
