        ...
        Joselfonseca\LaravelTactician\Providers\LaravelTacticianServiceProvider::class
        ...
    ]

You are done with the installation!

Usage

To use the command bus you can resolve the bus from the laravel container like so:

    $bus = app('Joselfonseca\LaravelTactician\CommandBusInterface');

Or you can inject it into a class constructor:

    use Joselfonseca\LaravelTactician\CommandBusInterface;

    class MyController extends BaseController
    {

        public function __construct(CommandBusInterface $bus)
        {
            $this->bus = $bus;
        }

    }

Once you have the bus instance you can add your handler for the command to be dispatched:

    $bus->addHandler('SomeCommand', 'SomeHandler');

Now you can dispatch the command with the middleware:

    // first parameter is the class name of the command
    // Second parameter is an array of input data to be mapped to the command
    // Third parameter is an array of middleware class names to be added to the stack
    $bus->dispatch('SomeCommand', [], []);

You can map the input data array of the Command's constructor with a plain list of arguments or the array itself. For example:

    // Send parameters in an array of input data ...    
    $bus->dispatch('SomeCommand', [
        'propertyOne'   => 'One',
        'propertyTwo'   => 'Two',
        'propertyThree' => 'Three',
    ], []);
    
    // ... and receive them as individual parameters ... 
    Class SomeCommand {
        public function __construct($propertyOne = 'A', $propertyTwo = 'B', $propertyThree = 'C'){
            //...
        }
    }
    
    // ... or receive array of input data itself 
        Class SomeCommand {
            public function __construct(array $data = [
                'propertyOne'   => 'A',
                'propertyTwo'   => 'B',
                'propertyThree' => 'C',
            ]){
                //...
            }
        }

Of course, you can use default values!

Example

Check out this example of the package implemented in a simple create order command https://gist.github.com/joselfonseca/24ee0e96666a06b16f92.

Bindings

You can configure the bindings for the locator, inflector, extractor and default bus by publishing the config file like so:

    php artisan vendor:publish

Then you can modify each class name and they will be resolved from the laravel container:

    return [
        // The locator to bind
        'locator' => 'Joselfonseca\LaravelTactician\Locator\LaravelLocator',
        // The inflector to bind
        'inflector' => 'League\Tactician\Handler\MethodNameInflector\HandleInflector',
        // The extractor to bind
        'extractor' => 'League\Tactician\Handler\CommandNameExtractor\ClassNameExtractor',
        // The bus to bind
        'bus' => 'Joselfonseca\LaravelTactician\Bus'
    ];

Generators

You can generate Commands and Handlers automatically using artisan:

artisan make:tactician:command Foo
artisan make:tactician:handler Foo

This will create FooCommand and FooHandler and place them in the app/Commands folder, please note that the words Command and Handler will be added to the class names respectively, so in the avobe example the clases created will be FooCommand and FooHandler.

To run both at once:

artisan make:tactician Foo

Middleware included

Laravel tactician includes some useful middleware you can use in your commands.

Database Transactions: This Middleware will run the command inside a database transaction, if any exception is thrown the transaction won't be committed and the database will stay intact, you can find this middleware in Joselfonseca\LaravelTactician\Middleware\DatabaseTransactions.
