Orlex: Organized Silex

Orlex é uma tentativa de dar uma estrutura mínima para o Silex sem extender, reescrever ou usar qualquer de hack.

Setting up Orlex is as simple as registering a service provider and pointing it to a directory of controllers:

<?php
$app = new \Silex\Application();

$app->register(new \Orlex\ServiceProvider(),[
    'orlex.controller.dirs' => [
        __DIR__ . '/app/Controllers',
    ],
]);

$app->run();

And then actually creating a controller:

<?php
namespace app\Controllers;

use Orlex\Annotation\Route;
use Orlex\Annotation\Before;
use Orlex\Annotation\After;

/**
 * @Route(path="/")
 */
class IndexController {
    /**
     * @Route(path="/", name="root")
     * @Before("beforeIndex")
     * @After("afterIndex")
     */
    public function indexAction() { /* Do Stuff */ }
    
    public function beforeIndex() { /* Do Stuff Before */ }
    public function afterIndex() { /* Do Stuff After */ }

    /**
     * @Route(path="/page/{id}", name="root_page", methods={"GET", "POST"})
     */
    public function pageAction($id) { /* Do Stuff With $id */ }
}

Installation

Orlex is provided as a composer package and requires PHP 5.4 and up. To use Orlex, simply add:

{
    "require": {
        "dcousineau/orlex": "dev-master"
    }
}

Controller Traits

Since Orlex seeks to be an "Organized Silex", it provides several convenience traits for your controller classes. These traits include a Twig trait, a Form trait, a Session trait.

To use them, your controller MUST use the \Orlex\ContainerAwareTrait.

NOTE: Any controller classes that use the aforementioned ContainerAwareTrait will have their container automatically set by the route compiler.

For example:

<?php
namespace app\Controllers;

use Orlex\Annotation\Route;
use Orlex\ContainerAwareTrait;
use Orlex\Controller\TwigTrait;

/**
 * @Route(path="/")
 */
class IndexController {
    use ContainerAwareTrait;
    use TwigTrait;
    
    /**
     * @Route(path="/", name="root")
     */
    public function indexAction() {
        return $this->render('index.html.twig', []);
    }
}

Obviously each respective trait will require their companion service provider to be already registered with the Silex application.

Custom Annotations

Orlex will support custom annotations. If you give your Orlex manager a directory and a namespace it will look for annotations contained there within:

<?php
//...
$app->register(new \Orlex\ServiceProvider(),[
    'orlex.controller.dirs' => [
        __DIR__ . '/app/Controllers',
    ],
    'orlex.annotation.dirs' => [
        __DIR__ => 'app\Annotation',
    ]
]);
//...

NOTE: The path key for annotation autoloading should be the root directory containing the entire namespace. If your annotation files are of the namespace app\Annotation and your annotation files are in /path/to/src/app/Annotation, the proper annotation configuration would be '/path/to/src' => 'app\Annotation'

If the annotation implements the Orlex\Annotation\RouteModifier interface, Orlex will allow it to alter the internal Silex controller created for that specific route/action:

<?php
namespace app\Annotation;

use Orlex\Annotation\RouteModifier;
use Silex\Controller;
use Silex\Application;

/**
 * @Annotation
 * @Target({"METHOD"})
 */
class Test implements RouteModifier {
    public function weight() { return 1; }

    public function modify($serviceid, Controller $controller, Application $app, \ReflectionClass $class, \ReflectionMethod $method) {
        $controller->before(function() {
            var_dump('From @Test annotation');
        });
    }
}

For more information on how to define annotations, please see the Doctrine Annotations documentation.

Expect this interface to possibly change in the future, particularly where the modify(…) signature is concerned.

Annotation Caching

Orlex is setup for easy annotation caching via the Doctrine\Common\Annotations\CachedReader reader. Simply include a cache directory:

<?php
$app->register(new \Orlex\ServiceProvider(),[
    'orlex.cache.dir' => __DIR__ . '/cache',
    'orlex.controller.dirs' => [
        __DIR__ . '/app/Controllers',
    ],
]);

And Orlex will setup a Doctrine\Common\Cache\FilesystemCache pointed at that directory and use said cache with the CachedReader. Alternatively you can override the orlex.cache service in your application container to return a Doctrine\Common\Cache\Cache object and it will be used instead.

Internal Behavior

Orlex works by scanning controller directories and inspecting annotations on all classes contained therewithin. Each controller class has a Service Controller created for it (as seen in the above modify(…) example's parameter $serviceid).

Orlex automatically registers the ServiceControllerServiceProvider with the specified Silex application.

Then, each method with a @Route annotation is created by performing an $app->match($path, "$serviceid:$methodName"). The result of $app->match(…) is a Silex Controller, which is then passed in a chain through each annotation that implements the Orlex\Annotation\RouteModifier interface, allowing it to chain anything that is required to the Silex controller.

Want To Help?

Please do! Just remember this is early alpha under going "api stress testing" (meaning I'm using this internally on a project and new features are being implemented on demand and going through trial-by-fire).

To-Do

• Clean up route compiler, become more DI friendly
• Post to packagist.org
• Functional Testing
• Annotation Caching
• Route Caching
• CLI Scaffolding (similar to Symfony's console command)
