Wheel.Base 2.0.0-beta3

Usage example

class Program
{
    static int Main(string[] args)
        => WheelAppBuilder.CreateDefault<Program>().Run(args);

    public static void Define(ICommandBuilder root)
    {
        root.DefaultCommand<HelloCommand>("hello");
        // ... add other definitions here ...
    }
}

class HelloCommand
{
    public static void Define(ICommandBuilder cmd)
    {
        cmd.Description = "A polite command";
        var nameArg = cmd.Argument("[name]", "Your name");

        cmd.Action = () => SayHello(nameArg.Value ?? "world");
    }

    private static void SayHello(string name)
    {
        Console.WriteLine("Hello, {0}.", name);
    }
}

This program can be launched with various arguments, for instance:

• -h for help on the program (including a list of defined commands)
• hello -h for help on command "hello"
• ? for interfactive mode
• hello -f monde to call the command "hello" with option "-f" and argument "monde"
• no argument to call the default command (which is also the "hello" command)

Define methods (in classes Program and HelloCommand) may also have parameters of types IServiceCollection (to register services for dependency injection) and/or IEnv (to get information about the current environment).

For commands returing values, assign cmd.Func instead of cmd.Action.

Property cmd.Services can be used to access the dependency injection container from the assigned action of function.

Files nlog.config and appsettings.ini can be created in any parent directory to configure logging and application settings.
