Benefits

• Be highly composable.
• Be immutable.

Features

Rings are implemented as immutable chains. When you enqueue a new decorator, a new stage will be created with the added decorator.

You can enqueue decorators that add functionality to the pipeline. You can enqueue decorators that filter the operations to be done on data. You can enqueue decorators which add sub pipelines.

This makes pipelines easy to reuse, highly composable, and minimizes side-effects.

Prerequisites

• PHP 7.2.0

Yes, that's the only hard requirement.

Installation

Use Composer

$ composer require guglielmopepe/rings

Usage

// create pipeline
$pipeline = new \Rings\Classes\Pipeline(new \SplQueue());

// add decorators: 
$pipeline->addDecorator(new \Rings\Classes\Decorator(function (\Rings\Interfaces\Data $data) {echo 'Stage 1 <br />';return $data;}));
$pipeline->addDecorator(new \Rings\Classes\Decorator(function (\Rings\Interfaces\Data $data) {echo 'Stage 2 <br />';return $data;}));
$pipeline->addDecorator(new \Rings\Classes\Decorator(function (\Rings\Interfaces\Data $data) {echo 'Stage 3 <br />';return $data;}));

// execute command
$data = $pipeline->execute(new \Rings\Classes\Data([]));

Documentation

Create pipeline like macro

// create pipeline
$pipeline = new \Rings\Classes\Pipeline(new \SplQueue());

// add decorators: 
$pipeline->addDecorator(new \Rings\Classes\Decorator(
    function (\Rings\Interfaces\Data $data)
    {
        return new \Rings\Classes\Data(['foo' => '***' . $data['foo'] . '***']);
    })
);

$pipeline->addDecorator(new \Rings\Classes\Decorator(
    function (\Rings\Interfaces\Data $data)
    {
        return new \Rings\Classes\Data(['foo' => '___' . $data['foo'] . '___']);
    })
);

// execute command
$data = $pipeline->execute(new \Rings\Classes\Data(['foo' => 'bar']));


// print ___***bar***___
echo $data['foo'];

Create pipeline with filter

// create pipeline
$pipeline = new \Rings\Classes\Pipeline(new \SplQueue());

// add decorators: 
$pipeline->addDecorator(new \Rings\Classes\Decorator(
    function (\Rings\Interfaces\Data $data)
    {
        if (strpos($data['foo'], '***') !== FALSE)
        {
            return $data;
        }

        return new \Rings\Classes\Data(['foo' => '***' . $data['foo'] . '***']);
    })
);

$pipeline->addDecorator(new \Rings\Classes\Decorator(
    function (\Rings\Interfaces\Data $data)
    {
        if (strpos($data['foo'], '___') !== FALSE)
        {
            return $data;
        }

        return new \Rings\Classes\Data(['foo' => '___' . $data['foo'] . '___']);
    })
);

// execute command
$data = $pipeline->execute(new \Rings\Classes\Data(['foo' => 'bar']));


// print ___***bar***___
echo $data['foo'];

// execute command
$data = $pipeline->execute(new \Rings\Classes\Data(['foo' => '***bar***']));


// print ***bar***
echo $data['foo'];

// execute command
$data = $pipeline->execute(new \Rings\Classes\Data(['foo' => '___bar___']));


// print ***bar***
echo $data['foo'];
