AvaloniaEdit

Supports syntax highlighting with TextMate grammars, code folding, multi-caret editing, and line virtualization, as detailed in the README's feature list, providing a comprehensive toolkit for code editors.

Implements line virtualization to render only visible lines, ensuring smooth performance even with large files, a key advantage highlighted in the philosophy section.

Fully customizable with intra-column adornments and support for custom TextMate grammars, allowing developers to tailor the editor to specific needs, as shown in the TextMate setup example.

Ported from the established AvalonEdit for WPF, bringing years of refinement and reliability to Avalonia applications, as noted in the project description.
