Hey @runeimp - thanks for the suggestion. This seems quite reasonable, but it also feels like it might only be used for the common "verbose" flag. I can't really think of another realistic use-case. I wonder if it would be better just to do it manually with something like
func main() {
var verbose int
for i, arg := range os.Args {
if strings.TrimRight(arg, "v") == "-" {
verbose = len(arg) - 1
os.Args = append(os.Args[:i], os.Args[i+1:]...)
break
}
}
var args struct {
...
}
arg.MustParse(&args)
...
}
This seems like a reasonably small amount of code for the special case of "-v", whereas implementing the general version inside go-arg and covering all the corner cases feels like it would add quite a bit of complexity.

I totally understand. I've seen it used in other places but verbosity is definitely the major use case. Thanks for the suggestion on how to work around it.
