C# option parsing library [Feb. 10th, 2008|07:54 pm]

I wrote a command line option parsing library in C#, based on Perl/CPAN's Getopt::Long. I think it is better than all the others available for C#.

Features include:
- Scalar, array, or hash types for option arguments
- Incrementable options (e.g. --verbose --verbose --verbose for 3x verbose)
- Option bundling if enabled (-zxvf=foo.tar.gz is the same as --gzip --extract --verbose --file foo.tar.gz)
- Generic argument types: you can ask that arguments be returned in any numeric type, string or bool, and it Does What You Mean
- Optional events to hook into in order to create custom options

Here's an example (NXGetoptLong/t/Simple.cs):

using System;
using System.Collections.Generic;

using NX.Getopt.Long;

using C = System.Console;

namespace NX.Getopt.Long.Tests {
    public class Simple {
        public static void Main(string[] args)
        {
            var p = new Parser();
            var gzip = new VoidOption("gzip") { Aliases = new string[] { "z" }
                };
            var extract = new VoidOption("extract") { Aliases = new string[]
                { "x" } };
            var verbose = new IncrementableOption("verbose");
            var file = new ScalarOption<string>("file");

            p.Bundling = Parser.BundlingOptions.Enabled;
            p.GetOptions(args, new Option[] { gzip, extract, verbose, file });

            C.WriteLine(gzip.Value);
            C.WriteLine(extract.Value);
            C.WriteLine(verbose.Value);
            C.WriteLine(file.Value);
        }
    }
}
