How would I implement an extra QEMU options flag in Nu?

[J-Cake]

So in order to allow me to pass extra arguments to Qemu, I've tried the following:

def main [--drive: path, ...extra: string] {
    qemu-system-x86_64 
        --drive $drive # not a real implemenation
        ...$extra 
}

This is problematic because Nu recognises the the --cdrom option I'd like to pass it as a flag to be interpreted by main, and because I never defined an option called that, it errors.

Next I tried a list of strings:

def main [--drive: path, extra: list] {
    # same as above
}

main --drive ./cheese.qcow2 ['--cdrom' 'os.raw']

which failed for the same reason.

What might be the best way to pass an argument-looking value to a function without it being interpreted as such?

Hi, you're looking for def --wrapped. This option allows rest args to absorb unknown flags as well, and it's meant exactly for this purpose.

Thanksss I never thought to look there :D
