Avalonia.Controls.Documents

Core document model library for Avalonia rich text controls. Provides rope-based text storage, a hierarchical document tree, text pointers, undo/redo, and snapshotting.

Features

  • Rope-based text storage (RopeTextStore) with O(log n) insert and delete
  • Document tree model (TextDocument, TextDocumentNode) for structural editing
  • Text pointer API (TextPointer, TextRange) with generation-based invalidation
  • Undo/Redo (UndoManager) with structural snapshot support
  • FlowDocument model with blocks (paragraphs, lists, tables, sections) and inlines
  • Document snapshots for thread-safe background serialization

Quick Start

var document = new FlowDocument();
var paragraph = new Paragraph();
paragraph.Inlines.Add(new Run("Hello, world!"));
document.Blocks.Add(paragraph);

## 12.1.4

### Fixes
- Modifying a displayed document's structure through a `RichTextElementCollection` (`Blocks`, `Inlines`, table rows/cells, list items) now updates the rendering immediately. Adding, inserting, removing, or clearing children of a live `FlowDocument` — including inside nested sections, and text-less blocks such as `BlockUIContainer` — previously changed the document model without notifying the render layer, so the display went stale (old blocks lingered, new blocks were missing) until the document was re-bound.
- Copying a selection that ends in a trailing empty paragraph — for example via Select-All — now preserves that empty paragraph when the content is pasted. The zero-length trailing paragraph was previously dropped, so copy/paste round-trips silently lost a document's final blank line. Range snapshots are now built by walking the document tree and capturing whole boundary blocks by node identity, rather than re-deriving blocks from start/end offsets, and `ContentEnd`/Select-All now reach a trailing empty block.
- Numbered (`TextMarkerStyle.Decimal`) list markers now render with the tabular-figures OpenType feature, so the digits line up into a clean column instead of staggering in fonts whose figures have proportional widths. Right-alignment already lined up the periods; this aligns the digits above them. Bullets and roman/latin markers are unaffected, and fonts without tabular figures fall back harmlessly to their default digits.
