Unable to specify array option with optional argument

[rcdailey]

I have the following:

internal class Settings : ServiceCommandSettings
{
    [CommandArgument(0, "[service]")]
    [Description("One of either sonarr or radarr. If not specified, defaults to all services.")]
    public SupportedServices? Service { get; [UsedImplicitly] init; }

    [CommandOption("-c|--configs")]
    [Description("One or more YAML configuration files to load & use")]
    [TypeConverter(typeof(FileInfoConverter))]
    public IFileInfo[] Configs { get; [UsedImplicitly] init; } = Array.Empty<IFileInfo>();
}

The goal is to specify my command like so:

myapp.exe --configs file1 file2

However, file2 gets treated as the value for [service], not as part of the --configs option. Am I going about this wrong or is this a lacking feature in the library?

You can not use space as a separator for multiple values in this way.

Either --configs="file1 file2" or --configs file1,file2 should work.

(If you choose a new separator instead of space, you'd probably need to change your converter accordingly.)

Would't -c file1 -c file2 work as expected, i.e. filling the Configs array with the two files, without having to worry about a separator in the FileInfoConverter?

[nils-a]

Yes. That would work, too.

Yeah, this is the approach I'm going to go for. It doesn't require any behavior customization which I like. Thanks for the advice.
