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

$3

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

$3

#### 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

$3

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

$3

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

$3

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+

$3

- Maintain backward compatibility with existing API
- Extensive testing with current test suite
- Consider keeping a legacy branch if breaking changes are unavoidable
