GoAopBridgeForLumen
===================

[](#goaopbridgeforlumen)

This is code copy and reference from goaop/framework and goaop/goaop-laravel-bridge, support for Lumen

The GoAopLumen adds support for Aspect-Oriented Programming via Go! AOP Framework for Lumen 5.4.\* applications.

Overview
--------

[](#overview)

Aspect-Oriented Paradigm allows to extend the standard Object-Oriented Paradigm with special instruments for effective solving of cross-cutting concerns in your application. This code is typically present everywhere in your application (for example, logging, caching, monitoring, etc) and there is no easy way to fix this without AOP.

AOP defines new instruments for developers, they are:

- Joinpoint - place in your code that can be used for interception, for example, execution of single public method or accessing of single object property.
- Pointcut is a list of joinpoints defined with a special regexp-like expression for your source code, for example, all public and protected methods in the concrete class or namespace.
- Advice is an additional callback that will be called before, after or around concrete joinpoint. For PHP each advice is represented as a `\Closure` instance, wrapped into the interceptor object.
- Aspect is a special class that combines pointcuts and advices together, each pointcut is defined as an annotation and each advice is a method inside this aspect.

You can read more about AOP in different sources, there are good articles for Java language and they can be applied for PHP too, because it's general paradigm. Alternatively, you can watch a [nice presentation about AOP in Laravel](http://slides.com/chrisflynn-1/aspect-oriented-architecture-in-laravel)

Installation
------------

[](#installation)

GoAopBridge can be easily installed with composer. Just ask a composer to download the bundle with dependencies by running the command:

```
$ composer require thieule/goaop-lumen
```

Add the `Go\Lumen\GoAopBridge\GoAopServiceProvider` to your bootstrap/app.php `providers` array:

```
// bootstrap/app.php

    $app->register(Go\Lumen\GoAopBridge\GoAopServiceProvider::class);
```

Make sure that this service provider is the **first item** in this list. This is required for the AOP engine to work correctly.

Configuration
-------------

[](#configuration)

The default configuration in the `config/go_aop.php` file. Copy this file to your own config directory to modify the values.

Configuration can be used for additional tuning of AOP kernel and source code whitelistsing/blacklisting.

```
// config/go_aop.php

return [
    /*
     |--------------------------------------------------------------------------
     | AOP Debug Mode
     |--------------------------------------------------------------------------
     |
     | When AOP is in debug mode, then breakpoints in the original source code
     | will work. Also engine will refresh cache files if the original files were
     | changed.
     | For production mode, no extra filemtime checks and better integration with opcache
     |
     */
    'debug' => env('APP_DEBUG', false),

    /*
     |--------------------------------------------------------------------------
     | Application root directory
     |--------------------------------------------------------------------------
     |
     | AOP will be applied only to the files in this directory, change it to app_path()
     | if needed
     */
    'appDir' => base_path(),

    /*

    'cacheDir' => storage_path('app/aspect'),

    /*

     |--------------------------------------------------------------------------
     |

    'cacheFileMode' => 511,

    'features' => 0,

     | White list of directories
     |--------------------------------------------------------------------------
     |

     */
    'includePaths' => [
        __DIR__.'/../app'
    ],

    /*
     |--------------------------------------------------------------------------
     | Black list of directories
     |--------------------------------------------------------------------------
     |
     | AOP will check this list to disable AOP for selected directories
     */
    'excludePaths' => [],

    /*
     |--------------------------------------------------------------------------
     | AOP container class
     |--------------------------------------------------------------------------
     |
     | This option can be useful for extension and fine-tuning of services
     */
    'containerClass' => GoAspectContainer::class,
];
```

Defining new aspects
--------------------

[](#defining-new-aspects)

Aspects are services in the Lumen application and loaded into the AOP container with the help of service provider that collects all services tagged with `goaop.aspect` tag in the container. Here is an example how to implement a logging aspect that will log information about public method invocations in the app/ directory.
