@damsfx it should probably allow the input to be returned unmodified if it doesn't exist within the array.

@LukeTowers If the entry doesn't exist in the array, it must be returned with another index anyway, right?

@damsfx I'm making the suggestion that if it doesn't exist in the array it should be returned unmodified. The method is intended to give you a unique filename provided the input of a desired filename and a list of already existing options. If the filename provided is already unique, then there's no need to modify it.

@LukeTowers So in a such case, the same filename is needed in the array of references to get the next incremented name.

The suggested change above should list all the cases that I think the method should need to handle, I've already updated the tests so it should just require a minor change in the method itself.

@LukeTowers Your modifications in tests goes to a failure for me.

// File already unique, return original
'winter.cms' => ['winter.cms', ['winter_1.cms']],

FAILED !
The function return wintert_2.cms in that case.

What I don't understand is why you want to return the unmodified value if it's unique.
In any case, we should return the incremented value! 🤯

(new Filesystem())->unique('winter.cms', ['test.cms']);   // winter_1.cms
(new Filesystem())->unique('winter.cms', []);             // winter_1.cms

@damsfx The tests are failing because the method doesn't currently have the logic to allow the name to be returned unmodified. The method claims to return a unique filename given the input of a desired filename and a list of existing filenames; why does it have to always return an incremented value if the desired filename isn't present?
