+# smartchok - Technical Hints
 
+## Chokidar 4.x Migration (2024)
+
+The module has been migrated from `@tempfix/watcher` to `chokidar` 4.x. Key changes:
+
+### Dependencies
+- **Removed**: `@tempfix/watcher` (a fork of fabiospampinato/watcher)
+- **Added**: `chokidar` 4.x and `picomatch`
+
+### Why picomatch?
+Chokidar 4.x removed built-in glob pattern support. We use `picomatch` to maintain backward compatibility and provide glob pattern matching functionality.
+
+### Implementation Details
+1. **Glob pattern extraction**: The `getGlobBase()` method extracts base directories from glob patterns
+2. **Pattern matching**: Each glob pattern is compiled to a picomatch matcher function
+3. **Event filtering**: File system events are filtered based on glob patterns before being emitted
+4. **Path normalization**: Paths are normalized to handle different formats (with/without leading ./)
+
+### Event Handling
+Chokidar 4.x events are mapped 1:1 with smartchok events:
+- `add`, `change`, `unlink`: File events
+- `addDir`, `unlinkDir`: Directory events  
+- `error`: Error events
+- `raw`: Raw events from underlying watchers
+- `ready`: Emitted when initial scan is complete
+
+### Testing
+All existing tests pass without modification, confirming backward compatibility is maintained.

+# Migration Plan: smartchok to Chokidar 4.x
+
+Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`
+
+## MIGRATION COMPLETED ✅
+
+All phases of the migration have been successfully completed:
+
+## Current State Analysis
+
+- **Current dependency**: `@tempfix/watcher` v2.3.0 (a fork of fabiospampinato/watcher)
+- **Target**: Chokidar v4.0.3
+- **Major challenge**: Chokidar 4.x removed glob support, but smartchok heavily uses glob patterns
+
+## Migration Plan
+
+### Phase 1: Preparation
+1. Install chokidar 4.x and glob library for pattern matching
+   - `pnpm install chokidar@^4.0.3`
+   - `pnpm install picomatch` (for glob pattern matching)
+   - `pnpm uninstall @tempfix/watcher`
+
+### Phase 2: Code Changes
+
+#### 2.1 Update Plugin Imports (ts/smartchok.plugins.ts)
+- Remove `@tempfix/watcher` import
+- Add `chokidar` import
+- Add `picomatch` for glob pattern matching
+
+#### 2.2 Update Smartchok Class (ts/smartchok.classes.smartchok.ts)
+- Replace watcher initialization with chokidar
+- Implement custom glob filtering using picomatch
+- Update event mapping to match chokidar's event names
+- Adjust watcher options to match chokidar's API
+
+#### 2.3 Handle Glob Patterns
+Since chokidar 4.x removed glob support, we need to:
+- Parse glob patterns to extract base directories
+- Use chokidar to watch base directories
+- Use picomatch to filter events based on glob patterns
+- Ensure backward compatibility with existing API
+
+#### 2.4 Event Mapping
+Map chokidar events to existing smartchok events:
+- Keep existing event names for backward compatibility
+- Ensure all current functionality is preserved
+
+### Phase 3: Testing
+1. Run existing tests to ensure backward compatibility
+2. Add new tests for glob pattern handling
+3. Test edge cases with complex glob patterns
+4. Verify performance with large file sets
+
+### Phase 4: Documentation
+1. Update readme.md to reflect the change to chokidar 4.x
+2. Document any API changes (if any)
+3. Update version number in package.json
+
+## Technical Details
+
+### Key Differences to Handle:
+1. **Glob Support**: Implement custom glob filtering layer
+2. **API Changes**: Adapt initialization and option passing
+3. **Event Names**: Map between different event naming conventions
+4. **Minimum Node Version**: Ensure compatibility with Node 14+
+
+### Risk Mitigation:
+- Maintain backward compatibility with existing API
+- Extensive testing with current test suite
+- Consider keeping a legacy branch if breaking changes are unavoidable
