Function userSetOption

cli/util.go:27–34

userSetOption returns true if the option was set by the user. This is helpful if the zero value of a flag is meaningful, and you need to distinguish between the user setting the flag to the zero value and the user not setting the flag at all.

(inv *serpent.Invocation, flagName string)

// to distinguish between the user setting the flag to the zero value and
// the user not setting the flag at all.
func userSetOption(inv *serpent.Invocation, flagName string) bool {
	for _, opt := range inv.Command.Options {
		if opt.Name == flagName {
			return !(opt.ValueSource == serpent.ValueSourceNone || opt.ValueSource == serpent.ValueSourceDefault)
		}
	}
	return false
}
