Is it possible to make an Enum optional?
outfmt: type: type: enum symbols: - clustal - clustal_num - fa - msf - nexus - phylip - selex - stockholm - vienna inputBinding: position: 13 prefix: --outfmt
I have tried
enum? but then it is not recognised as
?is just a shorthand for
[ <T>, "null"]. Try the latter.
Could you provide an example? I have tried a few alternatives with
nullbut I couldn't make it work.
