Tree with rounded corners?

[Bebby6]

Is there a way to have a rounded corners, like Table?

Thanks. Probably I can make a new Guide for it, but I don't know how.

Here's a guide using ╰ (U+2570 / BOX DRAWINGS LIGHT ARC UP AND RIGHT) instead of └ (U+2514 / BOX DRAWINGS LIGHT UP AND RIGHT) that will render a rounded corner.

public class RoundedLineTreeGuide : TreeGuide
{
    public override string GetPart(TreeGuidePart part)
    {
        return part switch
        {
            TreeGuidePart.Space => "    ",
            TreeGuidePart.Continue => "│   ",
            TreeGuidePart.Fork => "├── ",
            TreeGuidePart.End => "╰── ",
            _ => throw new ArgumentOutOfRangeException(nameof(part), part, "Unknown tree part."),
        };
    }
}

Here's what it looks like when used in the Trees example code.
