Multiple optional parameters

[akrabat]

Thanks for implementing the support of optional parameters.

How does multiple optional work? e.g. /news[/{year}][/{month}] gives:

Fatal error: Uncaught exception 'FastRoute\BadRouteException' with message 'Number of opening '['
and closing ']' does not match' in 
/www/dev/slim3/develop-testbed/vendor/nikic/fast-route/src/RouteParser/Std.php on line 31

Am I using the wrong syntax?

To follow up, nesting the square brackets is the solution. i.e. /news[/{year}[/{month}]]

@nikic I think this should be mentioned in docs.

@nikic I'm using Slim framework,
in Routes.php my code looks like
$app->get('/stores/[{storeName}]/categories', 'CategoryController:GETCategories');
I need to add {storeName} as mandatory variable but when I add the above pattern it is giving the following error.

Type: FastRoute\BadRouteException
Message: Optional segments can only occur at the end of a route

Could you please help to solve this issue, suggest me a solution how to use fastRoute in slim.
