This release replaces the old linting infrastructure with Ruff, a modern, fast Python linter and formatter written in Rust.

The following linting tools are no longer available as submodules or separate checkers:

• pylint - Replaced by Ruff PLE/PLR/PLW rules
• pyflakes - Replaced by Ruff F rules
• pycodestyle - Replaced by Ruff E/W rules
• mccabe - Replaced by Ruff C90 rules
• pydocstyle - Replaced by Ruff D rules
• pylama - No longer needed (was a wrapper)
• autopep8 - Replaced by Ruff format

Migration: Your existing g:pymode_lint_checkers configuration is automatically mapped to Ruff rules. No immediate action required, but see migration guide below.

• Ruff must be installed: pip install ruff
• Ruff is now an external dependency (not bundled as a submodule)

• g:pymode_lint_checkers values are now mapped to Ruff rule categories (not actual tools)
• Old tool-specific options (g:pymode_lint_options_*) are mapped to Ruff configuration
• New Ruff-specific options available:
  • g:pymode_ruff_enabled - Enable/disable Ruff linting
  • g:pymode_ruff_format_enabled - Enable/disable Ruff formatting
  • g:pymode_ruff_select - Select specific Ruff rules
  • g:pymode_ruff_ignore - Ignore specific Ruff rules
  • g:pymode_ruff_config_file - Specify Ruff config file path

• Formatting: :PymodeLintAuto now uses Ruff format instead of autopep8 (faster, PEP 8 compliant)
• Linting: Ruff may report different errors than pylint/pyflakes (usually fewer false positives)
• Performance: Significantly faster linting (10-100x improvement expected)

Removed submodules:

• submodules/pyflakes
• submodules/pycodestyle
• submodules/mccabe
• submodules/pylint
• submodules/pydocstyle
• submodules/pylama
• submodules/autopep8
• submodules/snowball_py (was only used by pydocstyle)
• submodules/appdirs (not used in pymode code)
• submodules/astroid (was only needed for pylint)
• submodules/toml (not used; Ruff handles its own TOML parsing)

Remaining submodules (3 total, down from 13):

• submodules/rope - Refactoring and code intelligence (essential)
• submodules/tomli - TOML parsing (required by pytoolconfig)
• submodules/pytoolconfig - Tool configuration (required by rope)

Repository cleanup:

• Removed git index entries for all removed submodules
• Cleaned up .git/modules references (freed ~90MB+ of repository space)
• Physical directories removed from working tree

• Migration Guide: See doc/MIGRATION_GUIDE.md for step-by-step instructions
• Configuration Mapping: See doc/RUFF_CONFIGURATION_MAPPING.md for detailed rule mappings
• Migration Script: Use scripts/migrate_to_ruff.py to convert your vimrc configuration
• Validation Script: Use scripts/validate_ruff_migration.sh to verify your setup

If you need to rollback to the old system:

1. Checkout previous version: git checkout v0.14.0
2. Install old dependencies: pip install pylint pyflakes pycodestyle mccabe pydocstyle autopep8
3. Restore old configuration in your .vimrc

Note: The old tools are no longer maintained as submodules. You'll need to install them separately if rolling back.

• Performance: Significantly faster linting and formatting with Ruff
• Maintenance: Reduced from 13 submodules to 3, simplifying dependency management
• Modern tooling: Using Ruff, a actively maintained, modern Python linter
• Unified configuration: Single tool configuration instead of multiple tool configs
• Better error messages: Ruff provides clearer, more actionable error messages

• Added comprehensive migration guide (doc/MIGRATION_GUIDE.md)
• Added Ruff configuration mapping documentation (doc/RUFF_CONFIGURATION_MAPPING.md)
• Updated doc/pymode.txt with Ruff configuration options
• Added migration tools (scripts/migrate_to_ruff.py, scripts/validate_ruff_migration.sh)

• All existing tests continue to pass
• Verified compatibility with Python 3.10-3.13
• Verified Docker environment compatibility
• Multi-platform CI testing: Added support for testing on Linux, macOS, and Windows
  • Windows PowerShell test script (scripts/cicd/run_vader_tests_windows.ps1)
  • Updated GitHub Actions workflow for cross-platform testing
  • Tests run on all platforms with Python 3.10, 3.11, 3.12, and 3.13
  • Platform-specific test result aggregation in PR summaries
  • Platform-specific fixes:
    • macOS: Fixed mapfile compatibility (bash 3.x/zsh), empty array handling, sed errors
    • Windows: Fixed path resolution across drive letters, /tmp/ path redirection to $TEMP
    • Added robust error handling and timeout support across all platforms
    • Improved Vim detection and PATH configuration for Windows

After many changes, including moving most of our dependencies from copied source code to submodules, and lot's of problems maintaining Python 2 and Python 3 support, this (0.10.x) is the last version of python-mode that will support Python 2. Some patches may be done in order to fix issues related to Python 2 or some backward compatible changes that can be applied.
