[Release] [Library] Command Parser

I made this library a while back for use in my own server programs and games that require user input via commands. Thought some of you might find it useful.

The Command Parser Framework makes it easy to create commands with optional and required arguments, grouped parameters, validation rules, permission levels, and more.

You can make commands return errors if they are not filled out completely, and also suggest commands in case of a misspelling.

Example:

This command enables a module of a bot. It uses the enum/option functionality to limit the parameter to a set of values. If snakebot is specified, a block parameter must also be accompanied (such as !enable snakebot red).

Parser = CommandParser
    .CreateNew()
    .UsePrefix("!")
    .OnError((o, error) => OnParseError(o, error));

Parser.AddCommand(Command
    .Create("Enable")
    .AddAlias("enable", "en")
    .SetDescription("Enable a module of the bot.")
    .SetAction((arguments, data) =>
    {
        var module = arguments.FromName("module");
        // TODO: Actually do something
        Console.WriteLine(module + " enabled!");
    })
    .AddArgument(Argument
        .Create("module")
        .AddOption(Argument.Create("snakebot")
           .AddArgument(Argument.Create("block")))
        .AddOption(Argument.Create("digbot"))
        .AddOption(Argument.Create("guestkicker"))
        .SetDefault("snakebot")
    ));

The command can then be used as:

(This is just a sample application. The commands would be accessible through EE chat if you called Parser.Parse(message) when a chat is received)

It can be downloaded from the latest release on GitHub. You can also install it through NuGet with: Install-Package Pyratron.Frameworks.Commands.Parser

Re: [Release] [Library] Command Parser

Wrote a small library to go along with this: https://github.com/Pyratron/LogConsole

There are already a lot of logging libraries out there, but I needed this to make it so commands can be typed in the console while data is being logged. (For example, writing chat messages to the console without overwriting what you have written)
