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);

## 12.2.3

### Fixes
- Applying a formatting property no longer leaves the old value behind on an outer inline. When several nested inlines cover the applied range in full, the value went to the innermost one, so a paragraph wrapped in Bold / Italic / Underline (what the readers produce for a paragraph that is styled end to end) kept the previous font size on the span above it. The value was shadowed, so nothing looked wrong until the wrapper was removed and the old size came back, and every consumer that flattens the inline hierarchy had to resolve precedence exactly right just to ignore it. The value now goes to the outermost inline covering that same range and is cleared from everything below it. Clearing a property over such a range now removes it from every level too, instead of stopping at the innermost one and letting an ancestor's value take over. Undo and redo restore the previous distribution unchanged.
