Long strings get line breaks inserted when written using AnsiConsole.WriteLine

[Gnbrkm41]

Title says all; It's kind of annoying when you print long single-line strings and copy & paste it somewhere else, only to find that the string is not single line anymore.

Note that this is essentially a duplicate of #845, but since the original issue is marked as closed I am reopening another issue to hopefully get any suggestions to get around this. Since I'm on the latest preview and am experiencing this... I guess the issue still remains as is?

The suggested solutions so far were:

• Use Console.WriteLine instead of AnsiConsole.WriteLine (recommended)
• Use int.MaxValue as Column width (NOT recommended)

  var width = AnsiConsole.Profile.Width;
  AnsiConsole.Profile.Width = int.MaxValue;
  AnsiConsole.MarkupLine(content);
  AnsiConsole.Profile.Width = width;  

My personal suggestion would be a markup option:

AnsiConsole.Markup("[nobr]a very long string[/]");

or an options object as extra parameter or as default:

var options = new AnsiConsoleOptions() {
NoBreak = true
};
AnsiConsole.DefaultOptions = options;
AnsiConsole.WriteLine("....", options);

The suggested solutions so far were:

I've used another workaround by wrapping render element with custom IRenderable that override Measure/ Render methods.
Downside of this workaround is when using link/decoration affected to the end of the console.
(I've confirmed that problems when changing Windows Terminal's size dynamically)

Example Code

using Spectre.Console;
using Spectre.Console.Rendering;

namespace SampleConsoleApp;

internal class Program
{
    static void Main()
    {
        var bufferSize = Console.BufferWidth;

        string longText = new string('a', bufferSize + 1);

        // By default long text is automatically breaked based on console buffer size.
        AnsiConsole.Console.WriteLine(longText);

        // When using **custom renderable}} wrapper. long text is not wrapped.
        AnsiConsole.Console.WriteLineNoBreak(longText);
        AnsiConsole.Console.WriteLineNoBreak(longText, new(foreground: ConsoleColor.Red));
        AnsiConsole.Console.WriteLineNoBreak(longText, new(background: ConsoleColor.Blue));
        AnsiConsole.Console.WriteLineNoBreak(longText, new(link: "https://google.com"));
        AnsiConsole.Console.WriteLineNoBreak(longText, new(decoration: Decoration.Strikethrough));
        AnsiConsole.Console.MarkupNoBreak(Markup.FromInterpolated($"[yellow]{longText}{Environment.NewLine}[/]"));
    }
}

public static class IAnsiConsoleExtensions
{
    public static void WriteNoBreak(this IAnsiConsole ansiConsole, string text, Style? style = null)
    {
        ansiConsole.Write(new NonBreakingRenderable(text, style));
    }

    public static void WriteLineNoBreak(this IAnsiConsole ansiConsole, string text, Style? style = null)
    {
        ansiConsole.Write(new NonBreakingRenderable($"{text}{Environment.NewLine}", style));
    }

    public static void MarkupNoBreak(this IAnsiConsole ansiConsole, Markup markup)
    {
        ansiConsole.Write(new NonBreakingRenderable(markup));
    }

    private sealed class NonBreakingRenderable : IRenderable
    {
        private readonly IRenderable _renderable;

        public NonBreakingRenderable(string text, Style? style)
        {
            _renderable = new Paragraph(text, style);
        }

        public NonBreakingRenderable(IRenderable renderable)
        {
            _renderable = renderable;
        }

        public Measurement Measure(RenderOptions options, int maxWidth) => _renderable.Measure(options, int.MaxValue);
        public IEnumerable<Segment> Render(RenderOptions options, int maxWidth) => _renderable.Render(options, int.MaxValue);
    }
}

@filzrev I like your idea. Thanks for the code.

I'm using spectre.console for logs, so this is how your code added to what I already have looks like.

using Spectre.Console;
using Spectre.Console.Rendering;

I'm not sure why, but I don't run into this when running my program in debug mode in Rider:

Code

using Spectre.Console;

const string moreThan80Chars =
    "asldjkhashjafhjkadfjhkashjksdakhjasjkhlasdhjklashjlkasjhkajhkdlasdhjkadjasdkjhs|asdkjlshdflkjshdfkjhsdfjhsdfkjhsdfkjhsdf";

Console.WriteLine(moreThan80Chars);
AnsiConsole.WriteLine(moreThan80Chars);

Console.WriteLine("Window Width:" + Console.WindowWidth);
Console.WriteLine("Buffer Width:" + Console.BufferWidth);

[ricardoboss]

Using Console.LargestWindowWidth might be the easiest workaround:

using Spectre.Console;

const string moreThan80Chars =
    "asldjkhashjafhjkadfjhkashjksdakhjasjkhlasdhjklashjlkasjhkajhkdlasdhjkadjasdkjhs|asdkjlshdflkjshdfkjhsdfjhsdfkjhsdfkjhsdf";

AnsiConsole.Console.Profile.Width = Console.LargestWindowWidth;

Console.WriteLine(moreThan80Chars);
AnsiConsole.WriteLine(moreThan80Chars);

Console.WriteLine("Window Width: " + Console.WindowWidth);
Console.WriteLine("Buffer Width: " + Console.BufferWidth);
Console.WriteLine("LargestWindowWidth: " + Console.LargestWindowWidth);

For some reason, this also changes the values for Console.WindowWidth and Console.BufferWidth.
In any case, this is better than setting Profile.Width to int.MaxValue or screwing with the measurements of widgets.
