よくある思い込み
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.
このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。
コントラクト
- 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.
