First I want to thank you for your great work!

Is there a way to provide enum parameters which are defined as flags and or'ed together?

[Flags]
enum FileType {
    Csv,
    Excel
}

[Verb]
void CreateFiles([Parameter] FileType fileType) { ... }

How to call the method with Csv and Excel enabled?

MySuperApp createfiles -filetype=Csv|Excel

Thanks in advance
Thomas

Interesting!
Currently you'll have to parse it by yourself but it's a great feature.
I'll implement.

Thanks,
Adrian

Apparently, flag enums are already supported using a comma:
MySuperApp createfiles -filetype=Csv,Excel

That's how Enum.Parse works, which is used by CLAP.

Cheers!

Don't forget to set a proper flag value to each enum value:

[Flags]
enum FileType
{
Csv = 1,
Excel = 2,
...4, 8, 16 ...
}

otherwise, the compiler will set the default values, which are 0,1,2,3,... which are not real flags.
