## [4.0.0] - 2025-10-16
|
||||
|
||||
### 🚀 Phase 5: Advanced Read Operations
|
||||
|
||||
This release adds frontmatter parsing capabilities to `read_note` and introduces specialized support for Excalidraw files. All features have been manually tested and refined based on user feedback.
|
||||
|
||||
#### Added
|
||||
|
||||
**Enhanced Tool: `read_note`**
|
||||
- **Frontmatter parsing** - New `parseFrontmatter` option to separate frontmatter from content
|
||||
- **Structured response** - Returns `ParsedNote` object with parsed YAML frontmatter
|
||||
- **Flexible options**:
|
||||
- `withFrontmatter` (default: true) - Include frontmatter in response
|
||||
- `withContent` (default: true) - Include full content in response
|
||||
- `parseFrontmatter` (default: false) - Parse and structure frontmatter
|
||||
- **Backward compatible** - Default behavior unchanged (returns raw content)
|
||||
- Returns structured JSON when `parseFrontmatter: true` with:
|
||||
- `path` - File path
|
||||
- `hasFrontmatter` - Boolean indicating presence
|
||||
- `frontmatter` - Raw YAML string
|
||||
- `parsedFrontmatter` - Parsed YAML object
|
||||
- `content` - Full file content
|
||||
- `contentWithoutFrontmatter` - Content excluding frontmatter
|
||||
|
||||
**New Tool: `read_excalidraw`**
|
||||
- Specialized tool for reading Excalidraw drawing files
|
||||
- **Metadata extraction** - Element count, compressed data status
|
||||
- **Preview text** - Extract text elements without parsing full drawing
|
||||
- **Optional compressed data** - Include full drawing data with `includeCompressed: true`
|
||||
- Returns structured `ExcalidrawMetadata` with:
|
||||
- `path` - File path
|
||||
- `isExcalidraw` - Validation boolean
|
||||
- `elementCount` - Number of drawing elements
|
||||
- `hasCompressedData` - Boolean for compressed files
|
||||
- `metadata` - Drawing metadata (appState, version)
|
||||
- `preview` - Text elements preview (optional)
|
||||
- `compressedData` - Full drawing data (optional)
|
||||
|
||||
**New Utilities (`src/utils/frontmatter-utils.ts`)**
|
||||
- `FrontmatterUtils` class for YAML parsing
|
||||
- `extractFrontmatter()` - Extract and parse YAML frontmatter using Obsidian's parseYaml
|
||||
- `extractFrontmatterSummary()` - Extract common fields (title, tags, aliases)
|
||||
- `hasFrontmatter()` - Quick check for frontmatter presence
|
||||
- `parseExcalidrawMetadata()` - Parse Excalidraw file structure
|
||||
- Handles edge cases: no frontmatter, malformed YAML, invalid Excalidraw files
|
||||
|
||||
**Type Definitions (`src/types/mcp-types.ts`)**
|
||||
- `ParsedNote` - Structured note with separated frontmatter
|
||||
- `ExcalidrawMetadata` - Excalidraw file metadata structure
|
||||
|
||||
**Implementation (`src/tools/note-tools.ts`)**
|
||||
- Enhanced `readNote()` method with options parameter
|
||||
- New `readExcalidraw()` method for Excalidraw files
|
||||
- Integrated frontmatter parsing with FrontmatterUtils
|
||||
- Maintains backward compatibility for existing clients
|
||||
|
||||
**Tool Registry (`src/tools/index.ts`)**
|
||||
- Updated `read_note` schema with new optional parameters
|
||||
- Registered `read_excalidraw` tool with comprehensive schema
|
||||
- Updated callTool to pass options to readNote and handle read_excalidraw
|
||||
|
||||
#### Improvements (Post-Testing)
|
||||
|
||||
- **Enhanced error handling** - Graceful handling of non-Excalidraw files with structured responses
|
||||
- **Comprehensive documentation** - Detailed field descriptions in tool schema with explicit categorization
|
||||
- **Full metadata exposure** - All Excalidraw metadata fields properly exposed per spec:
|
||||
- `elementCount` - Number of drawing elements (always returned)
|
||||
- `hasCompressedData` - Boolean for embedded images (always returned)
|
||||
- `metadata` - Object with appState and version (always returned)
|
||||
- `preview` - Text elements (conditional on includePreview)
|
||||
- `compressedData` - Full drawing data (conditional on includeCompressed)
|
||||
- **Enhanced type definitions** - JSDoc comments on all ExcalidrawMetadata fields
|
||||
- **Complete specification** - New EXCALIDRAW_METADATA_SPEC.md with comprehensive documentation
|
||||
|
||||
#### Bug Fixes (Post-Testing)
|
||||
|
||||
- **Fixed missing metadata fields** - Resolved issue where `elementCount`, `hasCompressedData`, and `metadata` were not returned
|
||||
- Added support for `compressed-json` code fence format (Excalidraw's actual format)
|
||||
- Detects compressed (base64) vs uncompressed JSON data
|
||||
- For compressed files: Returns `hasCompressedData: true` and `metadata.compressed: true`
|
||||
- For uncompressed files: Extracts actual element count and metadata
|
||||
- Multiple regex patterns to handle different Excalidraw formats
|
||||
- Always return metadata fields with appropriate values
|
||||
- **Known Limitation:** `elementCount` returns 0 for compressed files
|
||||
- Most Excalidraw files use compressed base64 format by default
|
||||
- Decompression would require pako library (not included to minimize dependencies)
|
||||
- Text elements are still extracted in `preview` field
|
||||
- Use `hasCompressedData: true` to identify compressed files
|
||||
- This is expected behavior, not a bug
|
||||
|
||||
#### Benefits
|
||||
|
||||
- **Better frontmatter handling** - Separate frontmatter from content for easier processing
|
||||
- **Excalidraw support** - First-class support for Excalidraw drawings with complete metadata
|
||||
- **Flexible reading** - Choose what data to include in responses
|
||||
- **Backward compatible** - Existing code continues to work unchanged
|
||||
- **Type-safe** - Structured responses with proper TypeScript types
|
||||
- **Robust** - Graceful error handling for edge cases
