NeoAgi.CommandLine

Emulation of CommandLineParser intending to work more at home in a GenericHost World

Default Behvior

The following is all that is necessary to parse options or throw a usage diagram:

using NeoAgi.CommandLine;

T opts = args.GetOps<T>();

T can be any type with a constructor. Any property decorated with (OptionAttribute)[OptionAttribute.cs] will be parsed according to the following semantics:

  • Loop through all strings in args[]
  • If the string begins with - use the next ordnal as the value
  • Properties marked as Required must have a value present
  • Optional values can be defaulted by setting the default initializer on the Property (e.g. public int MaxAge { get; set; } = 99;)

See OptionManager.Parse(string[] arr) for further information.

GetOps.cs handles the default interpertation of ExitDirective.cs which returns an exit code of 1 and prints the default usage help.

Help

To display the help without parsing args, provide --help as the first parameter.

Overriding Default Behaivor

If desired the entire exit process can be intercepted with a lambda of type Action<OptionManager, ExitDirective> on string[].GetOpt().

ProgramArguments opts = args.GetOps<ProgramArguments>((manager, exit) => {
    exit.ProcessHelp = false;
    exit.ExitCode = int.MaxValue;

    manager.PrintHelpErrors(Console.Error, manager.Errors);
    manager.PrintHelpOptions<ProgramArguments>(Console.Out);
});

Pay special attention of suppressing the default Help hanlder by setting exit.ProcessHelp to false if manipulating the output. Otherwise the default usage will fire in addition to other modifications.

OptionManager.PrintHelp<T> describes the default usage used.
