0.7.0

This release removed attaching objects to dispatcher. So you got rid of doing

$dispatcher->setObject('blog', $di->lazyNew('Controller\Blog'));

Instead you can add to route itself as a callable or can pass the fully qualified class name.

$router = $di->get('router');
$router->add('home', '/')
    ->addValues(array('controller' => function ($response) {
            return $response
                ->getBody()
                ->write("<p>Home page in html.</p>")
                ->withHeader('Content-Type', 'text/html');
        }
    ));

$router->add('greet', '/greet')
    ->addValues(array(
        'controller' => 'Controller\Greet',
        'action' => 'hello'
    ));

The controller now can return string, PSR-7 Response object or even a Response\Payload .

namespace Controller;

use Psr\Http\Message\ResponseInterface;
use Response\Payload;

class Blog
{
    public function hello()
    {
        $available = array(
            'text/html' => '.html',
            'application/json' => '.json',
        );
        // $data, $view, $layout, $available
        return new Payload(array('name' => 'Hari KT'), 'greet', null, $available);
    }

    public function returnString()
    {
        return "Hello World";
    }

    public function returnResponse(ResponseInterface $response)
    {
        return $response->withStatus(200)
                    ->withHeader('Content-Type', 'text/html')
                    ->write("returns response");
    }
}

From the payload it can detect the requested content type and send the corresponding response. By default it can send html only.

Please see the tests on the usage.
