Some checks are pending
Pre-commit / run (ubuntu-latest) (push) Waiting to run
- Add file_parser component with default implementation - Introduce SearchFilter schema for path and tag filtering - Implement filter functionality in BaseFileStore and LocalFileStore - Update file watcher to use parser-based filtering instead of suffix filters - Register new FILE_PARSER component enum - Add test_data directory to gitignore refactor: improve component imports and initialization - Fix relative imports in application.py - Add file_parser import to component init - Initialize registry dict when component type doesn't exist - Remove circular import in HttpService by using string annotation - Update config yaml to use proper component names refactor: enhance file watcher architecture - Replace MdFileWatcher with more flexible FullFileWatcher and LightFileWatcher - Remove suffix-based filtering in favor of parser-based approach - Update BaseFileWatcher to resolve parsers from app context - Remove unused watch_filter method refactor: update ReMe core functionality - Remove memory_path creation - Simplify dream and proactive methods to return empty strings - Update config defaults for HTTP service and component backends docs: update component configuration in paw.yaml - Change service backend from cmd to http - Rename components to use correct singular forms - Add default file parser and file watcher configurations - Set up local file store with default settings ``` Co-authored-by: huangsen <huangsen.huang@alibaba-inc.com>
