Häufige Annahme

When an option expecting a value is immediately followed by a registered flag like --verbose, ArgParser.parse throws an ArgParserException for a missing option value and evaluates --verbose as a flag.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• ArgParser.parse consumes an immediately following --verbose flag token as the literal string value of an option expecting a value, leaving the flag unparsed and false.
• assert(results['output'] == '--verbose');
• assert(results['verbose'] == false);
• assert(results.wasParsed('verbose') == false);
