Label

Option Label has no functional behaviour within a shell itself other than what a default help command outputs. Within a command documentation a type of an option is documented but this is not always super useful. Thus you may want to give better descriptive word for an option.

Label is not supported with legacy annotation.

  • Programmatic

  • Annotation

CommandRegistration labelOption() {
	return CommandRegistration.builder()
		.withOption()
			.longNames("arg")
			.label("MYLABEL")
			.and()
		.build();
}
void labelOption(
	@Option(label = "MYLABEL") String arg
) {
}

Defining label is then shown in help.
