# **docopt.net** is a .NET implementation of [docopt]



**docopt.net** is a parser for command-line arguments. It automatically derives

the parsing logic from the help text of a program containing its command-line

usage in [docopt] format. [docopt] is the formalization of conventions that have

been used for decades in help messages and man pages for describing a program's

interface. Below is an example of such a help text containing the usage for a

hypothetical program called Naval Fate:



    Naval Fate.



    Usage:

      naval_fate.exe ship new ...

      naval_fate.exe ship  move   [--speed=]

      naval_fate.exe ship shoot  

      naval_fate.exe mine (set|remove)   [--moored | --drifting]

      naval_fate.exe (-h | --help)

      naval_fate.exe --version



    Options:

      -h --help     Show this screen.

      --version     Show version.

      --speed=  Speed in knots [default: 10].

      --moored      Moored (anchored) mine.

      --drifting    Drifting mine.



## Usage



The following C# example shows one basic way to use **docopt.net**:



```c#

#nullable enable



using System;

using DocoptNet;



const string usage = @"Naval Fate.



Usage:

  naval_fate.exe ship new ...

  naval_fate.exe ship  move   [--speed=]

  naval_fate.exe ship shoot  

  naval_fate.exe mine (set|remove)   [--moored | --drifting]

  naval_fate.exe (-h | --help)

  naval_fate.exe --version



Options:

  -h --help     Show this screen.

  --version     Show version.

  --speed=  Speed in knots [default: 10].

  --moored      Moored (anchored) mine.

  --drifting    Drifting mine.



";



var arguments = new Docopt().Apply(usage, args, version: "Naval Fate 2.0", exit: true)!;

foreach (var (key, value) in arguments)

    Console.WriteLine("{0} = {1}", key, value);

```
