It allows developers to add support of AOP to every PHP application. Go! doesn't require any PECL-extentions, it neither uses any dark magic of Runkit nor evals, the library doesn't use DI-containers. The code with weaved aspects is fully readable and native, it can be easily debugged with XDebug. You can debug either classes or aspects. The main advantage of Go! is that potentially it can be installed in every PHP-application, because you don't have to change the application source code at all. As an example, with the help of 10-20 lines of code we can intercept all the public, protected and static methods in all the classes of application and display the name and the arguments of each method during its execution. [![Build Status](https://secure.travis-ci.org/lisachenko/go-aop-php.png?branch=master)](https://travis-ci.org/lisachenko/go-aop-php) Requirements ------------ Go! library is developed for PHP 5.4.0 and up, but it can partially work with PHP 5.3.0 code. Note that PHP versions before 5.4.0 will not work completely, if you try to use aspects for code that uses Late Static Binding (LSB) feature. Go! library will not work with eAccelerator. Installation ------------ Go! library can be installed with composer or manually with git submodules. Installation is quite easy: 1. Download go-aop-php using composer or git submodule 2. Create an application aspect kernel 3. Configure the aspect kernel in the front controller 4. Adjust the front controller of your application for proxying autoloading requests to the aspect kernel 5. Create an aspect 6. Register the aspect in the aspect kernel ### Step 1: Download go-aop-php using composer or git submodule Add Go! AOP library to your composer.json: ```js { "require": { "lisachenko/go-aop-php": "*" } } ``` Now ask composer to download the library with its dependencies by running the command: ``` bash $ php composer.phar update lisachenko/go-aop-php ``` Composer will install the library to your project's `vendor/lisachenko/go-aop-php` directory. Alternative way for installing the library is to use git submodules: ``` bash git submodule add https://github.com/lisachenko/go-aop-php vendor/alisachenko/go-aop-php ``` Dependencies should be also installed as submodules: ``` bash git submodule add https://github.com/Andrewsville/PHP-Token-Reflection vendor/andrewsville/php-token-reflection git submodule add https://github.com/doctrine/common vendor/doctrine/common ``` ### Step 2: Create an application aspect kernel The aim of this library is to provide easy AOP integration to your application. Your first step then is to create the `AspectKernel` class for your application. This class will manage all aspects of your application in one place. The library provides base class to make it easier to create your own kernel. To create your application kernel extend the abstract class `Go\Core\AspectKernel` ``` php init(array( // Configuration for autoload namespaces 'autoload' => array( 'Go' => realpath(__DIR__ . '/../vendor/lisachenko/go-aop-php/src/'), 'TokenReflection' => realpath(__DIR__ . '/../vendor/andrewsville/php-token-reflection/'), 'Doctrine\\Common' => realpath(__DIR__ . '/../vendor/doctrine/common/lib/') ), // Application root directory 'appDir' => __DIR__ . '/../', // Cache directory should be disabled for now 'cacheDir' => null // Include paths restricts the directories where aspects should be applied, or empty for all source files 'includePaths' => array( __DIR__ . '/../src/' ) )); ``` ### 4. Adjust the front controller of your application for proxying autoloading requests to the aspect kernel At this step we have a configured aspect kernel and can try to switch to it instead of default autoloader: ``` php // front-controller, for Symfony2 application it's web/app_dev.php // Comment default loader of application at the top of file // include __DIR__ .'/../vendor/autoload.php'; // for composer // include __DIR__ .'/../app/autoload.php'; // for old applications ``` ### 5. Create an aspect Aspect is the key element of AOP philosophy. And Go! library just uses simple PHP classes for declaring aspects! Therefore it's possible to use all features of OOP for aspect classes. As an example let's intercept all the methods and display their names: ``` php // Aspect/MonitorAspect.php namespace Aspect; use Go\Aop\Aspect; use Go\Aop\Intercept\FieldAccess; use Go\Aop\Intercept\MethodInvocation; use Go\Lang\Annotation\After; use Go\Lang\Annotation\Before; use Go\Lang\Annotation\Around; use Go\Lang\Annotation\Pointcut; /** * Monitor aspect */ class MonitorAspect implements Aspect { /** * Method that will be called before real method * * @param MethodInvocation $invocation Invocation * @Before("execution(public Example->*(*))") */ public function beforeMethodExecution(MethodInvocation $invocation) { $obj = $invocation->getThis(); echo 'Calling Before Interceptor for method: ', is_object($obj) ? get_class($obj) : $obj, $invocation->getMethod()->isStatic() ? '::' : '->', $invocation->getMethod()->getName(), '()', ' with arguments: ', json_encode($invocation->getArguments()), "
\n"; } } ``` Easy, isn't it? We declared here that we want to install a hook before the execution of all dynamic public methods in the class Example. This is done with the help of annotation `@Before("execution(public Example->*(*))")` Hooks can be of any types, you will see them later. But we doesn't change any code in the class Example! I can feel you astonishment now ) ### 6. Register the aspect in the aspect kernel To register the aspect just add an instance of it in the `configureAop()` method of the kernel: ``` php // app/ApplicationAspectKernel.php use Aspect/MonitorAspect; //... protected function configureAop(AspectContainer $container) { $container->registerAspect(new MonitorAspect()); } //... ``` Now you are ready to use the power of aspects! Feel free to change anything everywhere. Documentation ------------- Documentation about Go! library can be found at [official site][1]. Currently only Russian language is supported. If you'd like to contribute, please translate any part of the documentation to your language.

Different types of advice include "around", "before" and "after" * advices. * * Around advice is an advice that surrounds a joinpoint such as a method * invocation. This is the most powerful kind of advice. Around advices will * perform custom behavior before and after the method invocation. They are * responsible for choosing whether to proceed to the joinpoint or to shortcut * executing by returning their own return value or throwing an exception. * After and before advices are simple closures that will be invoked after and * before main invocation. * Framework model an advice as an PHP-closure interceptor, maintaining a * chain of interceptors "around" the joinpoint: * function(Joinpoint $joinPoint) { * echo 'Before action'; * // call chain here with Joinpoint->proceed() method * $result = $joinPoint->proceed(); * echo 'After action'; * return $result; * } * @author Lissachenko Alexander */ abstract class BaseAdvice implements Advice { /** * Constant for undefined order */ const ORDER_NOT_SET = -1;

* * // activate the autoloader * $loader->register(); * * In this example, if you try to use a class in the Symfony\Component * namespace or one of its children (Symfony\Component\Console for instance), * the autoloader will first look for the class under the component/ * directory, and it will then fallback to the framework/ directory if not * found before giving up. * * @author Fabien Potencier * * @api */ class UniversalClassLoader { private $namespaces = array();
