Hey @Keithcat1, do you mean when you run $ app pack
you're expecting that the help message for the pack
subcommand would be printed? I don't think we want that to be the default behavior for all applications using this library but you could get this behavior by using a required argument like this:
type packArgs struct {
Something string `arg:"required"`
}
var args struct {
Pack *packArgs `arg:"subcommand"`
}
arg.MustParse(&args)
Then if you run app pack
then you will get a message like this:
Usage: nested pack --something SOMETHING
error: --something is required
Unfortunately there is no way to manually print the full help message for a specific subcommand at present.
