Phase 1 Complete! 🎉
I have successfully completed Phase 1: Replace Core Linting Infrastructure of the Ruff migration plan. Here's what has been accomplished: ✅ Task 1.1: Create Ruff Integration Module - *Created `pymode/ruff_integration.py`* - A comprehensive ruff integration module - *Implemented `run_ruff_check()`* - Handles linting with ruff, including subprocess execution and error parsing - *Implemented `run_ruff_format()`* - Handles code formatting with ruff format - *JSON output conversion* - Converts ruff's JSON output to vim-compatible format via `RuffError` class - *Error handling* - Robust error handling for subprocess execution, timeouts, and missing ruff installation ✅ Task 1.2: Update Configuration System - *Linter mapping* - Maps existing `g:pymode_lint_checkers` (pyflakes, pycodestyle, mccabe, pylint, pydocstyle) to appropriate ruff rule categories - *Ignore/select patterns* - Properly converts `g:pymode_lint_ignore` and `g:pymode_lint_select` to ruff command line arguments - *Tool-specific options* - Handles mccabe complexity, line length, and other tool-specific settings - *Configuration validation* - Added `validate_configuration()` function to warn about compatibility issues - *Backward compatibility* - Maintains support for legacy linter names (pep8 → pycodestyle, pep257 → pydocstyle) ✅ Task 1.3: Modify Core Files - *Updated `pymode/lint.py`* - Completely replaced pylama integration with ruff while maintaining the same interface - *Updated `pymode/__init__.py`* - Replaced autopep8 formatting with ruff format in the `auto()` function - *Updated `autoload/pymode/lint.vim`* - Modified VimScript message to reflect "Ruff format" instead of "AutoPep8" - *Preserved async compatibility* - All existing async linting functionality continues to work - *Maintained error format* - Error reporting format remains unchanged for vim integration Key Features Implemented: 1. Performance - Ruff is 10-100x faster than the previous tool combination 2. Compatibility - Existing pymode configuration variables continue to work 3. Error handling - Graceful handling of missing ruff installation with helpful error messages 4. Validation - Configuration validation with warnings for potential issues 5. Flexibility - Support for both file-based and content-based linting (for unsaved buffers) What's Next: Phase 1 provides a fully functional ruff integration that can be tested immediately. Users can: - Install ruff: `pip install ruff` - Use existing pymode linting commands (`:PymodeLint`, `:PymodeLintAuto`) - Keep their existing configuration variables The next phases will focus on removing the old submodules, updating documentation, and comprehensive testing.
