-### Cache Decorators -**Enhanced decorator system**: -- `@cached(strategy, ttl)`: Generic caching with configurable strategy -- `@cached_method(ttl)`: Method caching (backward compatible) -- `@cached_api(service, ttl)`: API response caching -- `@cached_property(ttl)`: Cached property decorator - -### Cache Manager -**7 management operations**: -- `clear_all()`: Remove all cache entries -- `clear_by_prefix(prefix)`: Clear specific cache type -- `clear_expired()`: Remove expired entries -- `get_stats()`: Comprehensive statistics -- `clear_file_cache(file_path)`: Clear cache for specific file -- `get_cache_age(key)`: Get entry age -- `compact_cache()`: Remove empty directories - -### Command Palette Integration -**Integrated with Textual's command palette (Ctrl+P)**: -- Created `CacheCommandProvider` class -- 7 cache commands accessible via command palette: - - Cache: View Statistics - - Cache: Clear All - - Cache: Clear Extractors - - Cache: Clear TMDB - - Cache: Clear Posters - - Cache: Clear Expired - - Cache: Compact -- Commands appear alongside built-in system commands (theme, keys, etc.) -- Uses `COMMANDS = App.COMMANDS | {CacheCommandProvider}` pattern - -### Backward Compatibility -- Old import paths still work: `from renamer.decorators import cached_method` -- Existing extractors continue to work without changes -- Old `cache.py` deleted, functionality fully migrated -- `renamer.cache` now resolves to the package, not the file -
