I just want to know if there’s a trick for this.Say I have a route with optional variable `$mod`:
```
$app->get('/categories(/edit-:mod)', function($mod = 0) use ($app) {
}->name('category')
```
if I call its `urlFor('category')` it would output:
```
/categories/edit-:mod
```
even I did not supply parameter to `:mod`, is there a way to just make the output
```
/categories
```
since I do not want to to have the dummy variable and parameter to always show at the default link
Thanks!

I do not believe this is a feature in Slim 2 and we aren’t currently developing new features for Slim 2 we are looking at stuff for 4.0
That said, you could hack together something that would solve your immediate problem…
Example:
```auto
$uri = "/categories/edit-:mod"; // urlFor
$uri = substr($uri, 0, strrpos($uri, "/")); // /categories
```
