❔ Interactive both in y and x axis, in cmd

Hello :), I am trying to do an interactive menu in a command line application that use both the x and y axis, you navigate using keyboard arrows. I did a well working one that is only using the x axis, but with both this is way more complicated. I wrote a code that kind of works but for any reason the Console.Clear is not doing what i was expecting :

public static void Editing()
    {
        int x = 0;
        int y = 0;
        List<Option> x_options = new List<Option>();
        List<string> y_options = GetPrompt();
        List<string> special = new List<string>() { "%path", "%user", "%os", "%workingset", "%time", "%date", "%newline" };
        List<string> colors = new List<string>() { "%fore:", "%back:", "%style:" };
        while (true)
        {
            if (special.Contains(y_options[y]) || colors.Contains(y_options[y]))
            {
                x_options.Add(new Option(CustomCMD.GetValue("tips"), () => { }));
            }
            x_options.Add(new Option(CustomCMD.GetValue("edit"), () => { }));
            x_options.Add(new Option(CustomCMD.GetValue("add_right"), () => { }));
            x_options.Add(new Option(CustomCMD.GetValue("add_left"), () => { }));
            x_options.Add(new Option(CustomCMD.GetValue("delete"), () => { }));

            WriteComplexMenu(x_options, y_options, x_options[x], y_options[y]);
            ConsoleKeyInfo key = Console.ReadKey();
            if (key.Key == ConsoleKey.RightArrow)
            {
                y--;
                if (y < 0) y = y_options.Count - 1;
            }
            else if (key.Key == ConsoleKey.LeftArrow)
            {
                y++;
                if (y >= y_options.Count) y = 0;
            }
            else if (key.Key == ConsoleKey.UpArrow)
            {
                x--;
                if (x < 0) x = x_options.Count - 1;
            }
            else if (key.Key == ConsoleKey.DownArrow)
            {
                x++;
                if (x >= x_options.Count) x = 0;
            }
            else if (key.Key == ConsoleKey.Enter)
            {
            }
        }
    }

Editing is the main code that run the menu and handle the user input

CustomCMD.GetValue() is used to get the correct string, depends of the language (this is not the actual problem so i won't explain much) this is what is display without any input (and this is what i want) :

But once I do any input, the selected item is the good one, but the console is acting wierd :

RémiOP•2y ago

It duplicates the menu why

phaseshift•2y ago

i didnt see where you clear the screen

RémiOP•2y ago

in the begining of WriteComplexMenu which is called right after defining every option in the while loop

phaseshift•2y ago

but every time you loop, dont you add more options? so on the second time you have 2x each option? $debug is your friend

i can't debug because of the way i'm compiling I need to read json files, that are in the CustomCMD folder, but the compiled exe goes to CustomCMD/Debug/net7.0 this is this 🥲 it has been 2 hours while I was reading everything about buffer, Console.Clear thing etc ... x)

phaseshift•2y ago

add a sleep to your program. while it is sleeping, atach to the running process

RémiOP•2y ago

wdym by atach?

phaseshift•2y ago

phaseshift•2y ago

you can connect a debugger to a running process

RémiOP•2y ago

nice, is there a way to do it automatically right after the build ? right now it's moving the exe and other file automatically from net7.0 to the right folder usig a .bat script

phaseshift•2y ago

you'd be better off making the location that json files are read-from a command line argument ( and dont use a bat script to move the exe to a 'special' location) you can control the commandline args given when doing normal 'debug' from the project properties

Susko3•2y ago

or, load the json as ../../my_file.json instead of just my_file.json in your code you could also include the json in the build and set it to be copied to the output directory (not sure what the exact steps are, but I believe I've used the correct terminology)

RémiOP•2y ago

I'll check that But I've never find anything like that

Susko3•2y ago

I think it's usually right click on the file in Visual Studio
