TYPO3.Flow

We were thinking about a possibility to mark parts of the uriPattern optional. This could look something like:

$c->TYPO3Route_ServiceWithControllerAndFormat
    ->setUrlPattern('typo3/service/v1/[@controller].[@format](?orderby=[orderby])')
    ->setControllerComponentNamePattern('F3::@package::Service::Controller::@controllerController')
    ->setViewComponentNamePattern('F3::@package::Service::View::@controller::@action@format')
    ->setDefaults(
        array(
            '@package' => 'TYPO3',
            'orderby' => 'id'
        )
    );

the query part would be optional in this example. This would help to drastically reduce the amount of routes. You could do something like this too:

$c->myRoute
    ->setUrlPattern('typo3/service/v1/[@controller](.[@format])')
    ...

We'll have to resolve some logical challenges though.
E.g. we'll have to dissallow routes like this one:

$c->impossibleRoute
    ->setUrlPattern('static/[dynamic1](optional)[dynamic2]')
    ...

because the routing mechanismn could not tell where [dynamic1] ends.
