support for slice and/or array types - multiple values on one option about zig-args HOT 1 OPEN

Unlimited slice lengths are kinda weird, but what i wanted to support anyways at a point are custom types that have a parseCliOption function, so you can do this:

const options = try argsParser.parse(struct {
    outputs: ?OutputList = null, // slice, "--outputs output1,output2,output3 etc."
    resolution: ?Size = null, // array, "--resolution 1920x1080"

    pub const shorthands = .{
        .r = "resolution",
        .o = "outputs",
    };
}, &args, argsAllocator);

im not sure how difficult this would be to implement though ^_^;

The problem is that it's not unique anymore:

--outputs a b c d

Which of a, b, c, d is a positional argument, which one belongs to outputs?

One option would be to allow this:

--outputs a b c -- d

Where -- terminates the list.

The stuff in the first section is definitly planned (custom types), but let me think a bit about the second one (variadic length)

from zig-args.
