Converting from 1.9.71 to 2.9.1, having issues.

Hello. I am attempting to upgrade my commandlineparser code to the latest version and I am struggling.

The program's requirements are pretty simple: must have one and only one parameter, with a choice between two options.

Here is what I would ultimately like to have:

[Option("daysback", Required = false, Group = "onerequired", SetName = "daysback", Min = 0, Max = 999, HelpText = "Number of days back in time for run date.")]
public int? DaysBack { get; set; }

[Option("date", Required = false, Group = "onerequired", SetName = "date", HelpText = "Specific date for run date (yyyymmdd).")]
public string RunDate { get; set; }

Group would require at least one parameter, setname would make them mutually exclusive, max and min would check a value.

Unfortunately (according to docs), group and setname cannot be used together, so I had to drop group. And, min/max cannot be used on an int argument, so also dropped.

So now we look like this:

[Option("daysback", Required = false, SetName = "daysback", HelpText = "Number of days back in time for run date.")]
public int? DaysBack { get; set; }

[Option("date", Required = false, SetName = "date", HelpText = "Specific date for run date (yyyymmdd).")]
public string RunDate { get; set; }

Which is okay, but means that I have more checking to do myself.

Two questions please:

1. As is, this will parse cleanly if no arguments are given. Is there a way to set max/min number of required arguments?
2. Is there a way to generate the help screen text on demand? If I find argument errors with my post-parse checking, I'd like to output the same help screen that commandlineparser does.

Thanks.

Aucun fichier ni test n’est nommé. Commencez par examiner la documentation sur la validation des options de ligne de commande et la génération de l’aide référencée dans l’issue, puis retracez la gestion actuelle des groupes d’options, des ensembles, des contraintes numériques et de la sortie d’aide ; à la fin, il devrait être établi si les deux comportements demandés sont pris en charge et une voie claire pour les prendre en charge devrait être documentée ou implémentée.
