Shadow.Quack.Args 1.1.3

Shadow Quack Args

This package allows the easy population of values directly from a parameters (string[] args) array to a dynamically implemented immutable interface with the help of the base Shadow Quack package.

This means that there is almost no effort in adding additional command line parameters, it's as simple as just adding an additional get-only property to the interface.

An extension method .Populate<T>() is also provided to furthur simplify usage.

using System.Runtime.CompilerServices;
using Shadow.Quack;
using Shadow.Quack.Args;

namespace ExampleArgsApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var config = args.Populate<IConfig>();
            // var config = Duck.Implement<IConfig>((ArgsProxy) args);
            Console.WriteLine(
                !args.Any() 
                    ? Sugar.GetUsageInfo<IConfig>() 
                    : config.ToArgs());
        }
    }

    public interface IConfig
    {
        bool Flag { get; }
        string FileName { get; }
        int Port { get; }
        string SourceUrl { get; }
    }
}

a simple way to get usage information is to use Sugar.GetUsageInfo<T>() in the example above the output is below

 /flag[:true|false]
 /filename:"string"
 /port:int32
 /sourceurl:"string"

and if you want to reflect the parameters input back to the console or store them in a log-file you can use the .ToArgs() extension method using the above example like this ...

.\exampleArgsApp /flag /filename:"c:" /port:443 /sourceurl:"https://www.google.com"`

gives this output

/flag
/filename:"c:\"
/port:443
/sourceurl:"https://www.google.com"
