kohana: Remove need for default controller route

Question

I have a route as:

((?<directory>\w+)/?)?((?<controller>\w+)/?)?((?<action>\w+)/?)?((?<id>\d+))?

It works fine but it causes my system to have to include the default controller (index) for all routes to the sub routes. For example, if my page URI is /blog/post (where blog is the directory and post would be the action), my actual URI would have to be blog/index/post - I'd like to be able to fall back to just using blog/post instead.

So, I would like it to be routed to:

directory = blog
controller = index
action = post

Obviously this causes issues when the second parameter is actually a controller. For example directory/controller/action would be routed incorrectly.

Is there a routing method to detect that there are three word parameters, possibly followed by a numeric parameter, which can do what I need?

For claification:

param/param/param(?/id) would be: directory/controller/action(/id)
param/param(?/id) would be: directory/default_controller/action(/id)

i'd actually think that you want to alias blog/index/post with blog/post; insert it as a route before the "catch-all" route that you have; the "one big shoe fits all" approach is not always the best. Especially, if you only have 1 such particular use case.

edit:

"kohana's routing system" is daunting; can't make sense of the elephant they're trying to give birth to there... here are some other suggestions:

Take this issue to the manufacturer; this is definetely an FAQ question

Mess around with the regex patterns. Here's a snippet that might be useful (i put it inside a PHP test case, but you could easily decouple it)

public function testRoutePatterns(){
    $data = array(
    array(
        //most specific: word/word/word/id
        '~^(?P<directory>\w+)/(?P<controller>\w+)/(?P<action>\w+)/(?P<id>.*)$~i', 
        'myModule/blog/post/some-id',
        array('directory'=>'myModule', 'controller'=>'blog', 'action'=>'post', 'id'=>'some-id'), 
        true
    ),
    array(
        //less specific: word/word/id
        '~^(?P<directory>\w+)/(?P<action>\w+)/(?P<id>.*)$~i', 
        'blog/post/some-id',
        array('directory'=>'blog', 'action'=>'post'), //need to inject "index" controller via "defaults()" here i guess
        true
    ),
    );
foreach ($data as $d) {
    $matches = array();
    list($pattern, $subject, $expected, $bool) = $d;
    $actual = (bool) preg_match($pattern, $subject, $matches);
    $this->assertEquals($bool, $actual); //assert matching
    $this->assertEquals(array(), array_diff($expected, $matches)); //$expected contained in $matches
 }
}
