EasyConsoleFramework.AutoFac 1.0.1

Easy Console Framework

.NET Core library for easy building console application with command line parsing and inversion of control (IoC).
By default it's using Microsoft.Extensions.DependencyInjection (see configuration for AutoFac, custom).
It was designed for easy building application with multiple commands and low coupling.

How to use

1. Install nuget package ECF
2. Put in your program.cs this fragment:

// Program.cs
using ECF;

await new ECFHostBuilder()
    .UseDefaultCommands() // register all commands with CommandAttribute and default commands (help, exit, ...)
    .AddConfiguration(optional: true) // adds appsettings.json        
    .Configure((ctx, services, _) =>
    {
        ctx.Intro = $"This is example console application based on ECF. Version {typeof(Program).Assembly.GetName().Version}.\nType help to list available commands";
        ctx.HelpIntro = "Welcome to example program that showcases ECF framework. Enter one of command listed below";
        ctx.Prefix = "> ";
    })
    .RunAsync(args);

it will initialize and run your ECF console application

3. You can now add your first command

using ECF;

[Command("hello-world")]
class HelloWorldCommand : CommandBase
{
    private readonly IConfiguration configuration;

    [Required, Parameter("--name", "-n", Description = "Your name")]
    public string Name { get; set; }

    public HelloWorldCommand(IConfiguration configuration)
    {
        // you can use constructor to inject services
        this.configuration = configuration;
    }

    public override void Execute()
    {
        Console.WriteLine($"Hello {Name}");
    }
}

4. Run your program you should see welcome info

This is example console application based on ECF. Version 0.0.0.
Type help to list available commands

5. Invoke your command in console by typing

> hello-world -n John
