[jira] [Commented] (CLI-264) Short/Long options can be called using either '-' or '--' hyphens with no limitation

Isuranga Perera commented on CLI-264:
-------------------------------------

Above problem is a common problem to both DeafultParser and BasicParser (which is a depreciated version). So both versions have to be debugged.

> When using DefaultParser, any options can be accessed using either '\-' or '\-\-' as a prefix and so regardless whether they have been defined as short or long.
> the problem is in handleToken:
> 237        else if (token.startsWith("\-\-"))
> 238        {
> 239            handleLongOption(token);
> 240        }
> 241        else if (token.startsWith("\-") && !"\-".equals(token))
> 242        {
> 243            handleShortAndLongOption(token);
> 244        }
> Some logic should be added so that if an option has been defined as short  (e.g. \-h), if \-\-h is used, for instance, in the command line, an exception should be raised. Similarly for long options which are being called using only '\-' instead of '\-\-' as a prefix, an exception should also be fired.
