常见的想当然
Throwing InvalidArgumentError from a custom option parser causes exitOverride to rethrow the InvalidArgumentError instance, while throwing standard JavaScript Error instances is caught and formatted as a CommanderError.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- Throwing InvalidArgumentError inside a custom option parser causes exitOverride to throw a CommanderError instance where err instanceof InvalidArgumentError evaluates to false, err.code is 'commander.invalidArgument', and err.nestedError is undefined.
- Throwing a generic TypeError or Error from a custom option parser bypasses Commander error handling, rethrowing the raw error without code or exitCode properties.
- Invalid option choices trigger a CommanderError with code 'commander.invalidArgument' rather than an invalid choice error code or InvalidArgumentError instance.
- Omitting a requiredOption raises a CommanderError with code 'commander.missingMandatoryOptionValue' rather than 'commander.missingOption'.
- Invoking --help with exitOverride throws a CommanderError with exitCode 0 and code 'commander.helpDisplayed' rather than exiting cleanly or throwing an error code.
