Command

We will start for our Command Handler with our Command class. It's quite a foundation for it, so it makes sense to start with it. All commands should extend this Command class, otherwise it would be quite meaningless.

It's recommended to use namespaces and composer's autoloader using PSR-4.

We will start with this as template:

namespace YasminGuide\CommandHandler;

abstract class Command {
    /** @var \CharlotteDunois\Yasmin\Client */
    protected $client;

    /** @var \YasminGuide\CommandHandler\CommandHandler */
    protected $handler;

    /** @var string */
    public $path; // Will be assigned by the Command Handler

    protected $name = null;
    protected $description = null;

    function __construct(\YasminGuide\CommandHandler\CommandHandler $handler, string $name, string $description) {
        $this->client = $handler->client;
        $this->handler = $handler;

        $this->name = $name;
        $this->description = $description;
    }

    /**
     * Returns the command name.
     * @return string;
     */
    function getName() : string {
        return $this->name;
    }

    /**
     * Returns the command description.
     * @return string;
     */
    function getDescription() : string {
        return $this->description;
    }

    /**
     * Runs the command.
     * @return void
     * @throws \Throwable|\Exception|\Error
     */
    abstract function run(\CharlotteDunoi\Yasmin\Models\Message $message, array $args) : void;
}

I recommend to use docblocks to document property types and method return types. If you use something like PHP Integrator, it makes your life a lot easier. Also documenting type allows autocompletion.

We have a client property to make working with the client easier for us.
