User App Example

[joewez]

Is there an example of how to use the library... perhaps a simple terminal application?

Thanks!

There is this: https://github.com/darrenstarr/VtNetCore.UWP.

Thanks... but a UWP app is quite different from a .NET Winform app. I was not able to figure out how to translate the example into simple terminal application.

if you want to use it in a simple terminal application you probably want to setup something like this:

using System;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using VtNetCore.VirtualTerminal;
using VtNetCore.XTermParser;

namespace VtNetCoreTest
{
    internal class Program
    {
        private static CancellationTokenSource ctc;
        private static TelnetClient telnetcli;
        private static VirtualTerminalController vtController;
        static DataConsumer DataPart;
        
        public static async Task Main(string[] args)
        {
            await setupConnection("towel.blinkenlights.nl",23);
            await telnetcli.Connect();
            await telnetcli.Send("a");
           await WaitForItToWork();
        }
       static async Task WaitForItToWork()
        {
            while (true)
            {
                Console.Clear();
                Console.Write(vtController.GetScreenText());
                await Task.Delay(1000); // arbitrary delay
            }
        }
        public static async Task setupConnection(string host, int port)
        {
            ctc = new CancellationTokenSource();
            vtController = new VirtualTerminalController();
            vtController.ResizeView(80, 25);

            DataPart = new VtNetCore.XTermParser.DataConsumer(vtController);
            
            telnetcli = new TelnetClient(host, port, TimeSpan.FromSeconds(0), ctc.Token);
            telnetcli.DataReceived += (sender, s) => DataPart.Push(Encoding.ASCII.GetBytes(s));
            //telnetcli.LineReceived += (sender, s) => Console.WriteLine(s);
            //telnetcli.ConnectionClosed += (sender, args) => Console.WriteLine(args);
            //telnetcli.LineReceived += (sender, s) => OutputLog += s;
            vtController.SendData += (sender, args) => Console.WriteLine(args.Data);

        }
    }
}

the hardest issue is you must well regularly get the screentext

如果要在简单的终端应用程序中使用它，则可能需要设置如下所示的内容：

using System;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using VtNetCore.VirtualTerminal;
using VtNetCore.XTermParser;

namespace VtNetCoreTest
{
    internal class Program
    {
        private static CancellationTokenSource ctc;
        private static TelnetClient telnetcli;
        private static VirtualTerminalController vtController;
        static DataConsumer DataPart;
        
        public static async Task Main(string[] args)
        {
            await setupConnection("towel.blinkenlights.nl",23);
            await telnetcli.Connect();
            await telnetcli.Send("a");
           await WaitForItToWork();
        }
       static async Task WaitForItToWork()
        {
            while (true)
            {
                Console.Clear();
                Console.Write(vtController.GetScreenText());
                await Task.Delay(1000); // arbitrary delay
            }
        }
        public static async Task setupConnection(string host, int port)
        {
            ctc = new CancellationTokenSource();
            vtController = new VirtualTerminalController();
            vtController.ResizeView(80, 25);

            DataPart = new VtNetCore.XTermParser.DataConsumer(vtController);
            
            telnetcli = new TelnetClient(host, port, TimeSpan.FromSeconds(0), ctc.Token);
            telnetcli.DataReceived += (sender, s) => DataPart.Push(Encoding.ASCII.GetBytes(s));
            //telnetcli.LineReceived += (sender, s) => Console.WriteLine(s);
            //telnetcli.ConnectionClosed += (sender, args) => Console.WriteLine(args);
            //telnetcli.LineReceived += (sender, s) => OutputLog += s;
            vtController.SendData += (sender, args) => Console.WriteLine(args.Data);

        }
    }
}

最难的问题是您必须定期获取屏幕文本
