Default value for non-existing argument

[YauhenPyl]

Hello, thank you for the great library.

Is it possible to set different default values for ValueArgument if it is passed but without any value and if it is not passed at all? E.g.

internal class Arguments
{
    [ValueArgument(typeof(string), 'a', "argument", ValueOptional = true, DefaultValueNonExisting = "", DefaultValue = null, Optional = true)]
    public string Value { get; set; }
}

• Value will be 'Argument':

  my-tool.exe -a Argument

• Value will be "":

  my-tool.exe

• Value will be 'null':

  my-tool.exe -a

Thanks

Hi, it could be added but I can't give you any ETA atm. If you don't want to implement it yourself...

As a workaround, you could

• not specify DefaultValue
• after parsing the commandline, check the Parsed property of your argument and correct the value based on that

Added quick implementation for this idea.
