MeshWeaver.Markdown.Collaboration 3.0.0-preview1

MeshWeaver.Markdown.Collaboration

Provides collaborative editing infrastructure for markdown documents, including Operational Transformation (OT) for concurrent edits, range-anchored comments, and tracked changes with accept/reject workflows.

Features

• CollaborativeEditingCoordinator -- manages document state, applies OT transformations, and tracks active editing sessions with cursor positions
• Text operations: InsertOperation, DeleteOperation, CompositeOperation with version-based conflict resolution
• TextOperationTransformer for server-side OT transformation of concurrent edits
• RangeComment -- comments anchored to text ranges via embedded markdown markers (``)
• TrackedChange -- suggested edits (insertions, deletions, replacements) with pending/accepted/rejected status
• AnnotationSyncService for synchronizing annotations between the document and external storage
• MarkdownAnnotationParser for extracting and embedding annotation markers in markdown content
• Vector clock-based versioning and session presence awareness with stale session cleanup

Usage

var coordinator = new CollaborativeEditingCoordinator();

// Initialize a document
coordinator.InitializeDocument("doc-1", "# Hello World");

// Apply an edit
var result = coordinator.ApplyOperation("doc-1",
 new InsertOperation { Position = 13, Text = "\nNew line", UserId = "user1" },
 currentContent: "# Hello World");
