Console Bugs

[PratyushKing]

Area of Cosmos - What area of Cosmos are we dealing with?

Cosmos Inner-code bug.

Expected Behaviour - What do you think that should happen?

Identical to .NET Console behavior must be expected just with a 80x25 size.

Actual Behaviour - What unexpectedly happens?

Proper functioning of placements of text in code

Reproduction - How did you get this error to appear?

The code is:

public const int CWidth = 80;
public const int CHeight = 25;
public const string kernelName = "Test";
public const string kernelVersion = "v1.0";
public const ConsoleColor consoleKernelAccentColor = ConsoleColor.DarkCyan;

public static int finalSelection = 0;

public static void Run()
{
    var disks = new List<string>() { "0:\\", "1:\\", "2:\\" };

    Console.BackgroundColor = consoleKernelAccentColor;
    Console.ForegroundColor = ConsoleColor.White;
    Console.Clear();
    Console.WriteLine(kernelName + " " + kernelVersion + " Installer (via Cosmares)");

    Console.CursorLeft = 0;
    Console.CursorTop = CHeight;
    Console.BackgroundColor = ConsoleColor.DarkGray;
    Console.Write(new string(' ', CWidth));
    Console.CursorLeft = 0;
    Console.CursorTop = CHeight;
    Console.ForegroundColor = ConsoleColor.Black;
    Console.Write("Use arrow keys to move, space to select and enter to next.");

    var winX = CWidth / 16;
    var winY = 3;
    var winWidth = CWidth - (CWidth / 16) - 5;
    var winHeight = CHeight - 5;
    Console.BackgroundColor = ConsoleColor.White;
    for (var i = 0; i < winHeight; i++)
    {
        Console.CursorLeft = winX;
        Console.CursorTop = winY + i;
        Console.Write(new string(' ', winWidth));
    }

    Console.CursorLeft = winX + 2;
    Console.CursorTop = winY + 1;
    Console.Write("Select a disk:");

    var boxX = winX + 4;
    var boxY = winY + 3;
    var boxWidth = winWidth - 8; // (winWidth - (4*2))
    var boxHeight = winHeight - 6; // (winHeight - (3*2))
    Console.BackgroundColor = ConsoleColor.Gray;
    for (var i = 0; i < boxHeight; i++)
    {
        Console.CursorLeft = boxX;
        Console.CursorTop = boxY + i;
        Console.Write(new string(' ', boxWidth));
    }

    var selected = 0;
    var selectedVal = disks[selected];
    var hovered = 0;
    var hoveredVal = disks[hovered];
update:
    var diskIndex = 0;
    for (var i = 0; i < disks.Count; i++)
    {
        if (i == selected)
        {
            Console.BackgroundColor = consoleKernelAccentColor;
        } else if (i == hovered)
        {
            Console.BackgroundColor = ConsoleColor.DarkGray;
        }

        Console.CursorLeft = boxX;
        Console.CursorTop = boxY + i;
        Console.Write(new string(' ', boxWidth));
        Console.CursorLeft = boxX;
        Console.CursorTop = boxY + i;
        Console.Write(disks[i]);
        Console.BackgroundColor = ConsoleColor.Gray;
    }

    var key = Console.ReadKey(true);
    while (key.Modifiers != ConsoleModifiers.Control && key.Modifiers != ConsoleModifiers.Shift && key.Key != ConsoleKey.Escape)
    {
        if (key.Key == ConsoleKey.UpArrow && hovered - 1 > -1)
        {
            hovered--;
            goto update;
        }
        else if (key.Key == ConsoleKey.DownArrow && hovered + 1 < disks.Count)
        {
            hovered++;
            goto update;
        }
        else if (key.Key == ConsoleKey.Enter)
        {
            finalSelection = selected;
            return;
        }
        else if (key.Key == ConsoleKey.Spacebar)
        {
            selected = hovered;
            goto update;
        }
        key = Console.ReadKey(true);
    }
    return;
}

Version - Were you using the User Kit or Dev Kit? And what User Kit version or Dev Kit commit (Cosmos, IL2CPU, X#)?

It is the latest DevKit and its part of the main cosmos base.

Screenshots:

Expected first, and cosmos second

The CWidth and CHeight are used in both code so the 80x25 console can be used in the .NET one
