Console and GUI app in same EXE

[TonyValenti]

I just found this library and have some questions.

I have seen some MS utilities that are desktop applications but they have a console mode if you run them from the command line or with command line arguments.

I would like to do something similar in my app. Does this library have some way to determine if it was invoked as a console app? Or does it have some way to either create a console for a desktop app (or hide the console from a console app that wants to launch a WPF gui?

Termina.gui has nothing built in that will help. However, it is possible to do, at least on Windows. Last time I did it, I had two .exe files. Foo.exe and FooGui.exe. `foo —gui` would launch FooGui.exe IIRC it’s more tricky to make it be in a single .exe.

In this example im using System.CommandLine to parse the input arguments from the command line, but you can just as easily parse string[] args yourself.

public static async Task Main(string[] args)
{
    var rootCommand = new RootCommand();

    var guiOption = new Option<bool>("gui", "Starts the server with a GUI.");
    rootCommand.AddOption(guiOption);

    rootCommand.SetHandler(
        async (gui) =>
        {
            var runnable = gui ? StartGuiAsync() : StartServerAsync();
            await runnable;
        },
        guiOption
    );

    await rootCommand.InvokeAsync(args);
}

private static Task StartGuiAsync()
{
    Application.Init();
    Application.Run(new MainView());
    Application.Shutdown();

    return Task.CompletedTask;
}

public static async Task StartServerAsync()
{
    //Run without GUI.
}
