Danio: Args Parser for .NET

Overview

Danio is a .NET library to parse command line arguments implemented with the same design as gflags for C++.

You simply need to define your command line arguments (flags) as static fields in the classes where they are actually used in. Add the Attribute [Arg("My flag help.")] to the field in question and it is automatically parsed and assigned when the application starts.

Quick Example

namespace Ruibm.Danio.ExampleWithNugetPackage
{
    using System;
    using Ruibm.Danio;

    class Program
    {

        [Arg("Just a string.", IsMandatory=true)]
        public static string MyStringArg = "My lovely default value";

        [Arg("An int.", AllowedValues = new object[] { 10, 12, 21 })]
        private static int MyPrivateIntArg = 10;

        static void Main(string[] args)
        {
            Args.InitOrExitOnError(args);
            Console.WriteLine("[{0}]=[{1}]", "MyStringArg", MyStringArg);
            Console.WriteLine("[{0}]=[{1}]", "MyPrivateIntArg", MyPrivateIntArg);
            Console.WriteLine("Press Return to continue.");
            Console.ReadLine();
        }
    }
}
