Repeated arguments for options

[plivesey]

I want to do something like:

command --set x --set y --set z ARG1 ARG2

which would parse out as an array of strings for set. I don't think this is currently possible because the Options object takes a specific count and expects all the arguments to immediately follow the --set option. Is that right? Is this a good thing to add if so?

It's not possible yet without making a ArgumentDescriptor implementation, but it wouldn't be hard to implement. In fact, I have implemented this in the past in a tool that used Commander but never merged it into Commander yet.

I'll try dig it out, it was called VaradicOption which works very similar to https://github.com/kylef/Commander/blob/master/Sources/ArgumentDescription.swift#L30.

Cool and thanks. For now, I'd say this is a feature request, but vaguely possible I'll contribute this in the future.

This is now available in Commander 0.6.0.

Ah, I found it: https://github.com/kylef/Curassow/blob/87e1f9bb5297cf40a5713b649fd81be7dca9662d/Sources/Curassow.swift#L19-L56
