Install

Via Composer

$ composer require spekkionu/tactician-container-selfhandling

If you want to use the container aware commands you will also need to install league/container

Usage

Add MiddleWare

use League\Tactician\CommandBus;
use Spekkionu\Tactician\SelfExecuting\SelfExecutionMiddleware;

$commandBus = new CommandBus([
    // any other pre-execution middleware
    new SelfExecutionMiddleware(),
    // other middleware to handle non-self-executing commands
    // any other post-execution middleware
]);

Create a Command

Your commands must implement Spekkionu\Tactician\SelfExecuting\SelfExecutingCommand and have a handle() method.

The handle method must have no parameters.

use Spekkionu\Tactician\SelfExecuting\SelfExecutingCommand;

/**
 * Class ExampleSelfExecutingCommand
 */
class ExampleSelfExecutingCommand implements SelfExecutingCommand
{
    /**
     * @return string
     */
    public function handle()
    {
        // do work here
    }
}

Run Command

$commandBus->handle(new ExampleSelfExecutingCommand());

Container-Aware Self-Executing Commands

Container aware commands will have dependencies injected into the handle() method from league/container.

use League\Container\Container;
use League\Tactician\CommandBus;
use Spekkionu\Tactician\SelfExecuting\SelfExecutionMiddleware;

// Setup the Container
$container = new Container();
$container->delegate(
    new \League\Container\ReflectionContainer
);
$container->add('Logger', function() {
    return new Logger();
});

// Setup the command bus
$commandBus = new CommandBus([
    // any other pre-execution middleware
    new ContainerAwareSelfExecutionMiddleware($container),
    // other middleware to handle non-self-executing commands
    // any other post-execution middleware
]);

use Spekkionu\Tactician\SelfExecuting\SelfExecutingCommand;

/**
 * Class ExampleSelfExecutingCommand
 */
class ExampleSelfExecutingCommand implements SelfExecutingCommand
{
    /**
     * The logger will be injected automatically
     * @return string
     */
    public function handle(Logger $logger)
    {
        $logger->log('log message');
    }
}

$commandBus->handle(new ExampleSelfExecutingCommand());
