How can I ignore unknown flags/arguments?

[Sora233]

or collect them?

The passthrough option might do what you want, but also the classic -- ... works as you would expect.

Thanks for reply.
But passthrough or -- is not for me.
here's a example.

func main() {
	cmd := &struct {
		Cmd    string `arg:""`
		Number int `name:"number"`
		Extra  []string `arg:"" passthrough:""`
	}{}
	kong.Parse(cmd)
	spew.Dump(cmd)
}

It accepts the input --number 1 cmd extra but not --other 2 --number 1 cmd extra.
I want to collect the --other 2 as extra.

Ah, you want all interspersed unknown flags/arguments to pass through. No, that is not possible.

I see, thanks!
