Cannot define complex routes , i.e. date

[nowackipawel]

I've tried to define simple placeholder for date:
i.e.:

^20[0-5][0-9]\\-(1[0-2]|0[1-9])\\-(3[0-1]|[0-2][1-9]) // double "-" escaping

or

(20[0-5][0-9]\\-(1[0-2]|0[1-9])\\-(3[0-1]|[0-2][1-9]))

but I get

ErrorException

preg_match(): Unknown modifier '0' search →

SYSTEMPATH/Router/RouteCollection.php at line 1210

I think sth bad is happening here:
RouteCollection.php ::1192:
preg_match_all('/\(([^)]+)\)/', $from, $matches);

Well, for starters, those patterns doesn't work for me. When running standalone in Patterns app, I have to remove the \\ escaping for the dash in order for it to accurately match anything. Since the dash is part of the date pattern you're looking, it's treated as part of the string here. Not sure if that is messing the system up or not.

I'll write up a test to give it a try, though.

Cannot replicate. In the routes file:

$routes->addPlaceholder('date', '(20[0-5][0-9]-(1[0-2]|0[1-9])-(3[0-1]|[0-2][1-9]))');
$routes->get('(:date)', 'Home::dates/$1');

Visiting http://localhost:8081/2018-01-12 takes me where I expect it to.
