A simple command line parser based on Serde.NET and Spectre.Console.

Simple usage:

[GenerateDeserialize]
internal sealed partial record FileSizeCommand
{
    [CommandParameter(0, "searchPath",
        Description = "Path to search. Defaults to current directory.")]
    public string? SearchPath { get; init; }

    [CommandOption("-p|--pattern")]
    public string? SearchPattern { get; init; }

    [CommandOption("--hidden")]
    public bool? IncludeHidden { get; init; }
}

var console = AnsiConsole.Out;
var cmdOpt = CmdLine.TryParse<FileSizeCommand>(testArgs, console);
if (cmdOpt is {} cmd)
{
   // handle cmd
}

Hidden commands and options

Commands, parameters, options, and command groups can be marked as Hidden so they are still parseable but omitted from the generated help text. This is useful for experimental, deprecated, or internal-only functionality.

[GenerateDeserialize]
internal sealed partial record FileSizeCommand
{
    [CommandOption("-p|--pattern")]
    public string? SearchPattern { get; init; }

    // Parses normally, but does not appear in `CmdLine.GetHelpText` output.
    [CommandOption("--experimental", Hidden = true)]
    public bool? Experimental { get; init; }
}
