undo_redo/document_delta library
Classes
- CursorSnapshot
- Cursor / selection state captured at the time of the delta.
- DocumentDelta
- Represents a change to the document at the node level. Deltas are much smaller than full document snapshots because they store only the affected nodes, not the entire tree.
- NodeChange
- A single changed node: old JSON → new JSON at a specific index.
- NodeDeleteDelta
- Deletes a top-level node at a given index.
- NodeInsertDelta
- Inserts a new top-level node at a given index.
- NodeReplaceDelta
- Replaces one or more top-level nodes. This covers 95% of editor operations (typing, formatting, delete, enter, etc.).
