Choose your Cake Frosting 🍰 (Simple Menu)

[p10tyr]

Been wanting to do this for a long time and recently starting playing around with Cake.Frosting and discovered the Spectre.Console 😍

Thought I would share this simple code if somebody else was interested.

The tasks have to be within the executing assebmly so reflection can find it but you can tweak the reflector to load stuff from any where. It is just a way to load the task names string to pass in as a argument

If a user passes in their own arguments the menu does not show, eg CI or a user trying to do something specific with Cake

public static int Main(string[] args)
    {
        args = SplashScreen(args);

        return new CakeHost()
            .UseContext<BuildContext>()
            .Run(args);
    }

    public static string[] SplashScreen(string[] args)
    {
        if (args.Length > 0)
            return args;

        var tasks = GetAllTasks();

        var selectPromtp = new SelectionPrompt<string>()
               .Title("[green]Select the task you would like to run[/]")
               .AddChoices(tasks.ToArray());
       
        var selectedTask = AnsiConsole.Prompt<string>(selectPromtp);

        Console.WriteLine($"Selected {selectedTask} ");

        return new string[] { $"-t", selectedTask };
    }

    public static List<string> GetAllTasks()
    {
        return AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes())
                .Where(x => typeof(IFrostingTask).IsAssignableFrom(x) && !x.IsInterface && !x.IsAbstract)
                .Select(x => x.FullName)
                .Select(fullyQualifiedTaskName =>
                {
                    var attribute = (TaskNameAttribute)Attribute
                        .GetCustomAttribute(Type.GetType(fullyQualifiedTaskName), typeof(TaskNameAttribute));
                    return attribute.Name;
                })
                .ToList();
    }
