 # Changelog
 
-## TODO
+## [Unreleased] 0.15.0
+
+### BREAKING CHANGES: Ruff Migration
+
+This release replaces the old linting infrastructure with Ruff, a modern, fast Python linter and formatter written in Rust.
+
+#### Removed Linting Tools
+
+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.
+
+#### New Requirements
+
+- **Ruff must be installed:** `pip install ruff`
+- Ruff is now an external dependency (not bundled as a submodule)
+
+#### Configuration Changes
+
+- `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
+
+#### Behavior Changes
+
+- **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)
+
+#### Submodule Changes
+
+**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 Resources
+
+- **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
+
+#### Rollback Instructions
+
+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.
+
+### Improvements
+
+- **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
+
+### Documentation
+
+- 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`)
+
+### Testing
+
+- Added comprehensive Ruff integration tests (`tests/vader/ruff_integration.vader`)
+- 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

+# Docker Test Environment for python-mode
+
+This directory contains Docker configuration to run python-mode tests locally. **Note:** Docker is only used for local development. CI tests run directly in GitHub Actions without Docker.
+
+## Prerequisites
+
+- Docker
+- Docker Compose
+
+## Quick Start
+
+### Run Tests
+
+To run all tests in Docker (default version 3.13.0):
+
+```bash
+# Using the convenience script
+./scripts/user/run-tests-docker.sh
+
+# Or manually with docker-compose
+docker compose run --rm python-mode-tests
+```
+
+### Interactive Development
+
+To start an interactive shell for development:
+
+```bash
+docker compose run --rm python-mode-dev
+```
+
+## What's Included
+
+The Docker environment includes:
+
+- **Ubuntu 24.04** base image
+- **pyenv** for Python version management
+- **Multiple Python versions**: 3.10.13, 3.11.9, 3.12.4, 3.13.0
+- **Python 3.13.0** as default
+- **Vim built from source** with Python support for each Python version
+- All required system dependencies:
+  - GUI libraries (GTK, X11, etc.)
+  - Lua 5.2
+  - Perl
+  - Build tools
+  - Python build dependencies
+- **python-mode plugin** properly installed and configured
+- **Git submodules** initialized
+- **Test environment** matching the CI setup
+
+## Environment Details
+
+The container replicates the GitHub Actions environment:
+
+- Vim is built with `--enable-python3interp=yes` for each Python version
+- pyenv is installed at `/opt/pyenv`
+- Python versions are managed by pyenv:
+  - 3.10.13
+  - 3.11.9
+  - 3.12.4
+  - 3.13.0 (default)
+- Each Python version has its own Vim binary: `vim-3.10.13`, `vim-3.11.9`, etc.
+- Python config directory is automatically detected using `python-config --configdir`
+- python-mode is installed in `/root/.vim/pack/foo/start/python-mode`
+- Test configuration files are copied to the appropriate locations
+- All required environment variables are set
+
+## Test Execution
+
+### Local Testing (Docker)
+
+Tests are run using the Vader test framework via Docker Compose:
+
+```bash
+# Using docker compose directly
+docker compose run --rm python-mode-tests
+
+# Or using the convenience script
+./scripts/user/run-tests-docker.sh
+
+# Or using the Vader test runner script
+./scripts/user/run_tests.sh
+```
+
+### CI Testing (Direct Execution)
+
+In GitHub Actions CI, tests run directly without Docker using `scripts/cicd/run_vader_tests_direct.sh`. This approach:
+- Runs 3-5x faster (no Docker build/pull overhead)
+- Provides simpler debugging (direct vim output)
+- Uses the same Vader test suite for consistency
+
+**Vader Test Suites:**
+- **autopep8.vader** - Tests automatic code formatting (8/8 tests passing)
+- **commands.vader** - Tests Vim commands and autocommands (7/7 tests passing)
+- **folding.vader** - Tests code folding functionality
+- **lint.vader** - Tests linting functionality
+- **motion.vader** - Tests motion operators
+- **rope.vader** - Tests Rope refactoring features
+- **simple.vader** - Basic functionality tests
+- **textobjects.vader** - Tests text object operations
+
+All legacy bash tests have been migrated to Vader tests.
+
+## Testing with Different Python Versions
+
+You can test python-mode with different Python versions:
+
+```bash
+# Test with Python 3.11.9
+./scripts/user/run-tests-docker.sh 3.11
+
+# Test with Python 3.12.4
+./scripts/user/run-tests-docker.sh 3.12
+
+# Test with Python 3.13.0
+./scripts/user/run-tests-docker.sh 3.13
+```
+
+Available Python versions: 3.10.13, 3.11.9, 3.12.4, 3.13.0
+
+Note: Use the major.minor format (e.g., 3.11) when specifying versions.
+
+## Troubleshooting
+
+### Python Config Directory Issues
+
+The Dockerfile uses `python-config --configdir` to automatically detect the correct Python config directory. If you encounter issues:
+
+1. Check that pyenv is properly initialized
+2. Verify that the requested Python version is available
+3. Ensure all environment variables are set correctly
+
+### Build Failures
+
+If the Docker build fails:
+
+1. Check that all required packages are available in Ubuntu 24.04
+2. Verify that pyenv can download and install Python versions
+3. Ensure the Vim source code is accessible
+4. Check that pyenv is properly initialized in the shell
+
+### Test Failures
+
+If tests fail in Docker but pass locally:
+
+1. Check that the Vim build includes Python support for the correct version
+2. Verify that all git submodules are properly initialized
+3. Ensure the test environment variables are correctly set
+4. Confirm that the correct Python version is active
+5. Verify that pyenv is properly initialized
+
+## Adding More Python Versions
+
+To add support for additional Python versions:
+
+1. Add the new version to the PYTHON_VERSION arg in the Dockerfile
+2. Update the test scripts to include the new version
+3. Test that the new version works with the python-mode plugin
+4. Update this documentation with the new version information

+# Migration Guide: From Old Linting Tools to Ruff
+
+This guide helps you migrate from the old python-mode linting configuration (using pylint, pyflakes, pycodestyle, etc.) to the new Ruff-based system.
+
+## Overview
+
+Python-mode now uses **Ruff** instead of multiple separate linting tools. Ruff is:
+- **10-100x faster** than the old tools
+- **Single unified tool** replacing pyflakes, pycodestyle, mccabe, pylint, pydocstyle, autopep8
+- **Backward compatible** - your existing configuration is automatically mapped to Ruff rules
+
+## Quick Start
+
+### 1. Install Ruff
+
+```bash
+pip install ruff
+```
+
+Verify installation:
+```bash
+ruff --version
+```
+
+### 2. Your Existing Configuration Still Works!
+
+The good news: **You don't need to change anything immediately**. Your existing `g:pymode_lint_*` options are automatically mapped to Ruff rules.
+
+For example:
+```vim
+" Your old configuration still works!
+let g:pymode_lint_checkers = ['pyflakes', 'pycodestyle', 'mccabe']
+let g:pymode_lint_ignore = ["E501", "W"]
+```
+
+This is automatically converted to equivalent Ruff rules.
+
+### 3. (Optional) Migrate to Ruff-Specific Options
+
+For better control and performance, you can migrate to Ruff-specific options:
+
+```vim
+" Enable Ruff linting and formatting
+let g:pymode_ruff_enabled = 1
+let g:pymode_ruff_format_enabled = 1
+
+" Ruff-specific ignore rules (takes precedence over g:pymode_lint_ignore)
+let g:pymode_ruff_ignore = ["E501", "W"]
+
+" Ruff-specific select rules (takes precedence over g:pymode_lint_select)
+let g:pymode_ruff_select = []
+
+" Optional: Specify Ruff config file
+let g:pymode_ruff_config_file = ""
+```
+
+## Configuration Mapping
+
+### Legacy Options → Ruff Rules
+
+| Old Option | Ruff Equivalent | Notes |
+|------------|----------------|-------|
+| `g:pymode_lint_checkers = ['pyflakes']` | Ruff F rules | F401, F402, F403, etc. |
+| `g:pymode_lint_checkers = ['pycodestyle']` | Ruff E/W rules | E501, W292, etc. |
+| `g:pymode_lint_checkers = ['mccabe']` | Ruff C90 rules | C901 (complexity) |
+| `g:pymode_lint_checkers = ['pylint']` | Ruff PLE/PLR/PLW rules | PLE0001, PLR0913, etc. |
+| `g:pymode_lint_checkers = ['pep257']` | Ruff D rules | D100, D101, etc. |
+| `g:pymode_lint_ignore = ["E501"]` | Ruff ignore E501 | Same rule code |
+| `g:pymode_lint_select = ["W0011"]` | Ruff select W0011 | Same rule code |
+
+**Note:** Rule codes are mostly compatible. See `RUFF_CONFIGURATION_MAPPING.md` for detailed mappings.
+
+### Using Ruff Configuration Files
+
+Ruff supports configuration via `pyproject.toml` or `ruff.toml`:
+
+**pyproject.toml:**
+```toml
+[tool.ruff]
+line-length = 88
+select = ["E", "F", "W"]
+ignore = ["E501"]
+
+[tool.ruff.lint]
+select = ["E", "F", "W"]
+ignore = ["E501"]
+```
+
+**ruff.toml:**
+```toml
+line-length = 88
+select = ["E", "F", "W"]
+ignore = ["E501"]
+```
+
+Python-mode will automatically use these files if they exist in your project root.
+
+### Configuration Precedence
+
+Python-mode now supports flexible configuration precedence via `g:pymode_ruff_config_mode`:
+
+**Default Behavior (`"local_override"`):**
+- If your project has a local `ruff.toml` or `pyproject.toml` with `[tool.ruff]` section, it will be used
+- If no local config exists, python-mode settings serve as fallback
+- This ensures project-specific configs are respected while providing defaults
+
+**Using Only Local Config (`"local"`):**
+```vim
+let g:pymode_ruff_config_mode = "local"
+```
+Use this when you want python-mode to completely respect your project's Ruff configuration and ignore all python-mode settings.
+
+**Using Only Global Config (`"global"`):**
+```vim
+let g:pymode_ruff_config_mode = "global"
+```
+Use this to restore the previous behavior where python-mode settings always override local configs. Local config files will be ignored.
+
+**Note:** The default `"local_override"` mode is recommended for most users as it respects project standards while providing sensible defaults.
+
+## Step-by-Step Migration
+
+### Step 1: Verify Ruff Installation
+
+```bash
+pip install ruff
+ruff --version
+```
+
+### Step 2: Test Your Current Setup
+
+Your existing configuration should work immediately. Try:
+```vim
+:PymodeLint        " Should work with Ruff
+:PymodeLintAuto    " Should format with Ruff
+```
+
+### Step 3: (Optional) Create Ruff Config File
+
+Create `pyproject.toml` or `ruff.toml` in your project root:
+
+```toml
+[tool.ruff]
+line-length = 88
+select = ["E", "F", "W"]
+ignore = ["E501"]
+```
+
+### Step 4: (Optional) Migrate to Ruff-Specific Options
+
+Update your `.vimrc`:
+
+```vim
+" Old way (still works)
+let g:pymode_lint_checkers = ['pyflakes', 'pycodestyle']
+let g:pymode_lint_ignore = ["E501"]
+
+" New way (recommended)
+let g:pymode_ruff_enabled = 1
+let g:pymode_ruff_format_enabled = 1
+let g:pymode_ruff_ignore = ["E501"]
+```
+
+## Common Scenarios
+
+### Scenario 1: Using pyflakes + pycodestyle
+
+**Before:**
+```vim
+let g:pymode_lint_checkers = ['pyflakes', 'pycodestyle']
+let g:pymode_lint_ignore = ["E501"]
+```
+
+**After (automatic):**
+- Works immediately, no changes needed!
+
+**After (Ruff-specific):**
+```vim
+let g:pymode_ruff_enabled = 1
+let g:pymode_ruff_ignore = ["E501"]
+" Ruff automatically includes F (pyflakes) and E/W (pycodestyle) rules
+```
+
+### Scenario 2: Using autopep8 for formatting
+
+**Before:**
+```vim
+" autopep8 was used automatically by :PymodeLintAuto
+```
+
+**After:**
+```vim
+let g:pymode_ruff_format_enabled = 1
+" :PymodeLintAuto now uses Ruff format (faster!)
+```
+
+### Scenario 3: Custom pylint configuration
+
+**Before:**
+```vim
+let g:pymode_lint_checkers = ['pylint']
+let g:pymode_lint_options_pylint = {'max-line-length': 100}
+```
+
+**After:**
+```vim
+let g:pymode_ruff_enabled = 1
+" Use pyproject.toml for Ruff configuration:
+" [tool.ruff]
+" line-length = 100
+" select = ["PLE", "PLR", "PLW"]  # pylint rules
+```
+
+## Troubleshooting
+
+### Ruff not found
+
+**Error:** `ruff: command not found`
+
+**Solution:**
+```bash
+pip install ruff
+# Verify:
+ruff --version
+```
+
+### Different formatting output
+
+**Issue:** Ruff formats code differently than autopep8
+
+**Solution:** This is expected. Ruff follows PEP 8 and Black formatting style. If you need specific formatting, configure Ruff via `pyproject.toml`:
+
+```toml
+[tool.ruff.format]
+quote-style = "double"
+indent-style = "space"
+```
+
+### Rule codes don't match
+
+**Issue:** Some rule codes might differ between old tools and Ruff
+
+**Solution:** See `RUFF_CONFIGURATION_MAPPING.md` for detailed rule mappings. Most common rules (E501, F401, etc.) are compatible.
+
+### Performance issues
+
+**Issue:** Linting seems slower than expected
+
+**Solution:** 
+1. Ensure Ruff is installed: `pip install ruff`
+2. Check if legacy options are causing overhead (migrate to Ruff-specific options)
+3. Verify Ruff config file is being used
+
+## Breaking Changes
+
+### Removed Tools
+
+The following tools are **no longer available** as separate checkers:
+- `pylint` (use Ruff PLE/PLR/PLW rules)
+- `pyflakes` (use Ruff F rules)
+- `pycodestyle` (use Ruff E/W rules)
+- `mccabe` (use Ruff C90 rules)
+- `pep257` (use Ruff D rules)
+- `autopep8` (use Ruff format)
+
+### Configuration Changes
+
+- `g:pymode_lint_checkers` values are mapped to Ruff rules (not actual tools)
+- `g:pymode_lint_options_*` are mapped to Ruff configuration
+- Old tool-specific options may not have exact equivalents
+
+### Behavior Changes
+
+- **Formatting:** Ruff format may produce slightly different output than autopep8
+- **Linting:** Ruff may report different errors than pylint/pyflakes (usually fewer false positives)
+- **Performance:** Should be significantly faster
+
+## Rollback Instructions
+
+If you need to rollback to the old system:
+
+1. **Checkout previous version:**
+   ```bash
+   git checkout <previous-version-tag>
+   ```
+
+2. **Reinstall old dependencies** (if needed):
+   ```bash
+   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.

+# Ruff Configuration Mapping Guide
+
+This document explains how python-mode configuration options map to Ruff settings, and how to migrate from the old linting tools to Ruff.
+
+## Overview
+
+Python-mode now uses Ruff for linting and formatting, replacing:
+- **pyflakes** - Syntax errors and undefined names
+- **pycodestyle** - PEP 8 style guide enforcement
+- **mccabe** - Cyclomatic complexity checking
+- **pylint** - Comprehensive static analysis
+- **pydocstyle** - Docstring style checking
+- **pylama** - Multi-tool linting wrapper
+- **autopep8** - Automatic PEP 8 formatting
+
+## Configuration Options
+
+### Legacy Options (Still Supported)
+
+These options are maintained for backward compatibility and are automatically converted to Ruff rules:
+
+#### `g:pymode_lint_checkers`
+**Default:** `['pyflakes', 'pycodestyle', 'mccabe']`
+
+Maps to Ruff rule categories:
+- `'pyflakes'` → Ruff `F` rules (pyflakes)
+- `'pycodestyle'` → Ruff `E` and `W` rules (pycodestyle)
+- `'mccabe'` → Ruff `C90` rule (mccabe complexity)
+- `'pylint'` → Ruff `PL` rules (pylint)
+- `'pydocstyle'` → Ruff `D` rules (pydocstyle)
+
+**Example:**
+```vim
+let g:pymode_lint_checkers = ['pyflakes', 'pycodestyle']
+" This enables Ruff rules: F (pyflakes), E (pycodestyle errors), W (pycodestyle warnings)
+```
+
+#### `g:pymode_lint_ignore`
+**Default:** `[]`
+
+Maps to Ruff `--ignore` patterns. Supports both legacy error codes (E501, W503) and Ruff rule codes.
+
+**Example:**
+```vim
+let g:pymode_lint_ignore = ['E501', 'W503', 'F401']
+" Ruff will ignore: E501 (line too long), W503 (line break before binary operator), F401 (unused import)
+```
+
+#### `g:pymode_lint_select`
+**Default:** `[]`
+
+Maps to Ruff `--select` patterns. Selects specific rules to enable.
+
+**Example:**
+```vim
+let g:pymode_lint_select = ['E', 'F']
+" Ruff will only check E (pycodestyle errors) and F (pyflakes) rules
+```
+
+### New Ruff-Specific Options
+
+These options provide direct control over Ruff behavior:
+
+#### `g:pymode_ruff_enabled`
+**Default:** `1`
+
+Enable or disable Ruff linting entirely.
+
+**Example:**
+```vim
+let g:pymode_ruff_enabled = 1  " Enable Ruff (default)
+let g:pymode_ruff_enabled = 0  " Disable Ruff
+```
+
+#### `g:pymode_ruff_format_enabled`
+**Default:** `1`
+
+Enable or disable Ruff formatting (replaces autopep8).
+
+**Example:**
+```vim
+let g:pymode_ruff_format_enabled = 1  " Enable Ruff formatting (default)
+let g:pymode_ruff_format_enabled = 0  " Disable Ruff formatting
+```
+
+#### `g:pymode_ruff_select`
+**Default:** `[]`
+
+Ruff-specific select rules. If set, overrides `g:pymode_lint_select`.
+
+**Example:**
+```vim
+let g:pymode_ruff_select = ['E', 'F', 'W', 'C90']
+" Enable pycodestyle errors, pyflakes, pycodestyle warnings, and mccabe complexity
+```
+
+#### `g:pymode_ruff_ignore`
+**Default:** `[]`
+
+Ruff-specific ignore patterns. If set, overrides `g:pymode_lint_ignore`.
+
+**Example:**
+```vim
+let g:pymode_ruff_ignore = ['E501', 'F401']
+" Ignore line too long and unused import warnings
+```
+
+#### `g:pymode_ruff_config_file`
+**Default:** `""`
+
+Path to Ruff configuration file (pyproject.toml, ruff.toml, etc.). If empty, Ruff will search for configuration files automatically.
+
+**Example:**
+```vim
+let g:pymode_ruff_config_file = '/path/to/pyproject.toml'
+" Use specific Ruff configuration file
+```
+
+#### `g:pymode_ruff_config_mode`
+**Default:** `"local_override"`
+
+Controls how Ruff configuration is resolved. This option determines whether local project configuration files (`ruff.toml`, `pyproject.toml`) or python-mode settings take precedence.
+
+**Modes:**
+- `"local"`: Use only the project's local Ruff config. Python-mode settings are ignored. Ruff will auto-discover configuration files in the project hierarchy.
+- `"local_override"`: Local config takes priority. If a local Ruff config file exists, it will be used. If no local config exists, python-mode settings serve as fallback.
+- `"global"`: Use only python-mode settings. Local config files are ignored (uses `--isolated` flag). This restores the previous behavior where python-mode settings always override local configs.
+
+**Example:**
+```vim
+" Respect project's local Ruff config (recommended for team projects)
+let g:pymode_ruff_config_mode = "local"
+
+" Use local config if available, otherwise use pymode defaults (default)
+let g:pymode_ruff_config_mode = "local_override"
+
+" Always use pymode settings, ignore project configs
+let g:pymode_ruff_config_mode = "global"
+```
+
+**Note:** The default `"local_override"` mode provides the best user experience by respecting project-specific configurations while providing sensible defaults when no local config exists.
+
+## Migration Examples
+
+### Example 1: Basic Configuration
+
+**Before (using legacy tools):**
+```vim
+let g:pymode_lint_checkers = ['pyflakes', 'pycodestyle']
+let g:pymode_lint_ignore = ['E501', 'W503']
+```
+
+**After (using Ruff - backward compatible):**
+```vim
+" Same configuration works automatically!
+let g:pymode_lint_checkers = ['pyflakes', 'pycodestyle']
+let g:pymode_lint_ignore = ['E501', 'W503']
+```
+
+**After (using Ruff-specific options):**
+```vim
+let g:pymode_ruff_select = ['F', 'E', 'W']  " pyflakes, pycodestyle errors/warnings
+let g:pymode_ruff_ignore = ['E501', 'W503']
+```
+
+### Example 2: Advanced Configuration
+
+**Before:**
+```vim
+let g:pymode_lint_checkers = ['pyflakes', 'pycodestyle', 'mccabe', 'pylint']
+let g:pymode_lint_options_mccabe = {'complexity': 10}
+let g:pymode_lint_options_pycodestyle = {'max_line_length': 88}
+```
+
+**After:**
+```vim
+" Option 1: Use legacy options (still works)
+let g:pymode_lint_checkers = ['pyflakes', 'pycodestyle', 'mccabe', 'pylint']
+let g:pymode_lint_options_mccabe = {'complexity': 10}
+let g:pymode_lint_options_pycodestyle = {'max_line_length': 88}
+
+" Option 2: Use Ruff-specific options + config file
+let g:pymode_ruff_select = ['F', 'E', 'W', 'C90', 'PL']
+let g:pymode_ruff_config_file = 'pyproject.toml'
+" In pyproject.toml:
+" [tool.ruff]
+" line-length = 88
+" [tool.ruff.mccabe]
+" max-complexity = 10
+```
+
+### Example 3: Disabling Formatting
+
+**Before:**
+```vim
+" No direct way to disable autopep8
+```
+
+**After:**
+```vim
+let g:pymode_ruff_format_enabled = 0  " Disable Ruff formatting
+```
+
+## Rule Code Reference
+
+### Pycodestyle Rules (E, W)
+- **E** - Errors (syntax, indentation, etc.)
+- **W** - Warnings (whitespace, line breaks, etc.)
+- Common codes: `E501` (line too long), `E302` (expected blank lines), `W503` (line break before binary operator)
+
+### Pyflakes Rules (F)
+- **F** - Pyflakes errors
+- Common codes: `F401` (unused import), `F811` (redefined while unused), `F841` (unused variable)
+
+### McCabe Rules (C90)
+- **C90** - Cyclomatic complexity
+- Configured via `g:pymode_lint_options_mccabe` or Ruff config file
+
+### Pylint Rules (PL)
+- **PL** - Pylint rules
+- Common codes: `PLR0913` (too many arguments), `PLR2004` (magic value)
+
+### Pydocstyle Rules (D)
+- **D** - Docstring style rules
+- Common codes: `D100` (missing docstring), `D400` (first line should end with period)
+
+## Configuration File Support
+
+Ruff supports configuration via `pyproject.toml` or `ruff.toml` files. Python-mode will automatically use these if found, or you can specify a path with `g:pymode_ruff_config_file`.
+
+**Example pyproject.toml:**
+```toml
+[tool.ruff]
+line-length = 88
+select = ["E", "F", "W", "C90"]
+ignore = ["E501"]
+
+[tool.ruff.mccabe]
+max-complexity = 10
+```
+
+## Backward Compatibility
+
+All legacy configuration options continue to work. The migration is transparent - your existing configuration will automatically use Ruff under the hood.
+
+## Troubleshooting
+
+### Ruff not found
+If you see "Ruff is not available", install it:
+```bash
+pip install ruff
+```
+
+Verify installation:
+```bash
+./scripts/verify_ruff_installation.sh
+```
+
+### Configuration not working
+1. Check that `g:pymode_ruff_enabled = 1` (default)
+2. Verify Ruff is installed: `ruff --version`
+3. Check configuration file path if using `g:pymode_ruff_config_file`
+4. Review Ruff output: `:PymodeLint` and check for errors
+
+### Performance issues
+Ruff is significantly faster than the old tools. If you experience slowdowns:
+1. Check if Ruff config file is being read correctly
+2. Verify Ruff version: `ruff --version` (should be recent)
+3. Check for large ignore/select lists that might slow down rule processing

+The GitHub Actions CI workflow has been enhanced to test python-mode on **Linux**, **macOS**, and **Windows** platforms, ensuring compatibility across all major operating systems.
+
+## Changes Made
+
+### 1. Multi-Platform GitHub Actions Workflow
+
+**File:** `.github/workflows/test.yml`
+
+The workflow now includes three separate test jobs:
+
+- **`test-linux`**: Tests on Ubuntu (Python 3.10, 3.11, 3.12, 3.13)
+- **`test-macos`**: Tests on macOS (Python 3.10, 3.11, 3.12, 3.13)
+- **`test-windows`**: Tests on Windows (Python 3.10, 3.11, 3.12, 3.13)
+
+Each platform runs the full Vader test suite with all supported Python versions.
+
+### 2. Windows PowerShell Test Script
+
+**File:** `scripts/cicd/run_vader_tests_windows.ps1`
+
+A new PowerShell script specifically designed for Windows CI environments:
+
+- Handles Windows path separators (`\` vs `/`)
+- Uses PowerShell-native commands and error handling
+- Converts paths appropriately for Vim on Windows
+- Generates JSON test results compatible with the existing summary system
+
+**Key Features:**
+- Automatic Vader.vim installation
+- Windows-compatible vimrc generation
+- Proper path handling for Windows filesystem
+- JSON test results generation matching Linux/macOS format
+
+### 3. Platform-Specific Setup
+
+#### Linux (Ubuntu)
+- Uses `vim-nox` package (installed via `apt-get`)
+- Uses existing `run_vader_tests_direct.sh` bash script
+- No changes required - already working
+
+#### macOS
+- Installs Vim via Homebrew (`brew install vim`)
+- Uses existing `run_vader_tests_direct.sh` bash script
+- Compatible with macOS filesystem (Unix-like)
+
+#### Windows
+- Installs Vim via Chocolatey (`choco install vim`)
+- Uses new PowerShell script `run_vader_tests_windows.ps1`
+- Handles Windows-specific path and shell differences
+
+## Test Matrix
+
+The CI now tests:
+
+| Platform | Python Versions | Test Script |
+|----------|----------------|-------------|
+| Linux (Ubuntu) | 3.10, 3.11, 3.12, 3.13 | `run_vader_tests_direct.sh` |
+| macOS | 3.10, 3.11, 3.12, 3.13 | `run_vader_tests_direct.sh` |
+| Windows | 3.10, 3.11, 3.12, 3.13 | `run_vader_tests_windows.ps1` |
+
+**Total:** 12 test configurations (3 platforms × 4 Python versions)
+
+## Test Results
+
+Test results are uploaded as artifacts with platform-specific naming:
+- `test-results-linux-{python-version}`
+- `test-results-macos-{python-version}`
+- `test-results-windows-{python-version}`
+
+The PR summary job aggregates results from all platforms and generates a comprehensive test summary.
+
+## Benefits
+
+1. **Cross-Platform Compatibility**: Ensures python-mode works correctly on all major operating systems
+2. **Early Issue Detection**: Platform-specific issues are caught before release
+3. **Better User Experience**: Users on Windows and macOS can be confident the plugin works on their platform
+4. **Comprehensive Coverage**: Tests all supported Python versions on each platform
+
+## Platform-Specific Considerations
+
+### Windows
+- Uses PowerShell for script execution
+- Path separators converted for Vim compatibility
+- Chocolatey used for Vim installation
+- Windows-specific vimrc configuration
+
+### macOS
+- Uses Homebrew for package management
+- Unix-like filesystem (compatible with Linux scripts)
+- May have different Vim version than Linux
+
+### Linux
+- Standard Ubuntu package manager
+- Reference platform (most thoroughly tested)
+- Uses `vim-nox` for non-GUI Vim
+
+## Running Tests Locally
+
+### Linux/macOS
+```bash
+bash scripts/cicd/run_vader_tests_direct.sh
+```
+
+### Windows
+```powershell
+pwsh scripts/cicd/run_vader_tests_windows.ps1
+```
+
+## Troubleshooting
+
+### Windows Issues
+
+**Vim not found:**
+- Ensure Chocolatey is available: `choco --version`
+- Check PATH includes Vim installation directory
+- Try refreshing PATH: `refreshenv` (if using Chocolatey)
+
+**Path issues:**
+- PowerShell script converts paths automatically
+- Ensure vimrc uses forward slashes for runtime paths
+- Check that project root path is correctly resolved
+
+### macOS Issues
+
+**Vim not found:**
+- Ensure Homebrew is installed: `brew --version`
+- Install Vim: `brew install vim`
+- Check PATH includes `/usr/local/bin` or Homebrew bin directory
+
+### General Issues
+
+**Test failures:**
+- Check Python version matches expected version
+- Verify Ruff is installed: `ruff --version`
+- Check Vader.vim is properly installed
+- Review test logs in `test-logs/` directory
+
+## Future Improvements
+
+Potential enhancements:
+- [ ] Test on Windows Server (in addition to Windows-latest)
+- [ ] Test on specific macOS versions (e.g., macOS-12, macOS-13)
+- [ ] Test with Neovim in addition to Vim
+- [ ] Add performance benchmarks per platform
+- [ ] Test with different Vim versions per platform

+Pymode uses Ruff for code checking and formatting. Ruff is a fast Python linter
+and formatter written in Rust that replaces multiple tools (pyflakes, pycodestyle,
+mccabe, pylint, pydocstyle, autopep8) with a single, unified tool.
 
-        Pymode uses Pylama library for code checking. Many options like skip
-        files, errors and etc could be defined in `pylama.ini` file or modelines.
-        Check Pylama documentation for details.
+        Ruff configuration can be defined in `pyproject.toml` or `ruff.toml` files.
+        See Ruff documentation for details: https://docs.astral.sh/ruff/
 
-        Pylint options (ex. disable messages) may be defined in `$HOME/pylint.rc`
-        See pylint documentation.
+        For backward compatibility, existing `g:pymode_lint_*` options are mapped

+--------------------------------------
+
+Ruff is significantly faster than the old linting tools (pylint, pyflakes, etc.).
+If you experience any issues:
 
-In some projects pylint may check slowly, because it also scans imported
-modules if possible. Try using another code checker: see
-|'g:pymode_lint_checkers'|.
+- Ensure Ruff is installed: `pip install ruff`
+- Check Ruff configuration in `pyproject.toml` or `ruff.toml`
+- Use |pymode-ruff-configuration| for Ruff-specific options
+- Legacy options are automatically mapped to Ruff rules
 
 You may set |exrc| and |secure| in your |vimrc| to auto-set custom settings
 from `.vimrc` from your projects directories.

+A suggested structure is the following: add your test to `tests/vader/` (2)
+as a `.vader` file. You can make use of the existing sample files at
+`tests/test_python_sample_code` (3). Vader tests use Vimscript syntax and
+can directly test python-mode functionality. See `tests/vader/setup.vim` (4)
+for test setup utilities. The test runner is at `scripts/user/run_tests.sh` (5).
+
+6. Testing Environment: The project uses Docker for consistent testing across
+different Python versions. See `README-Docker.md` for detailed information about
+the Docker testing environment.
+
+7. CI/CD: The project uses GitHub Actions for continuous integration, building
+Docker images for each supported Python version and running tests automatically.
+
+8. Supported Python Versions: The project currently supports Python 3.10.13,
+3.11.9, 3.12.4, and 3.13.0. All tests are run against these versions in the
+CI environment.
+
+9. Docker Testing: To run tests locally with Docker:
+    - Use `./scripts/user/run-tests-docker.sh` to run tests with the default Python version
+    - Use `./scripts/user/run-tests-docker.sh 3.11` to test with Python 3.11.9
+    - Use `./scripts/user/test-all-python-versions.sh` to test with all supported versions

+# Docker Testing Environment
+
+For consistent testing across different Python versions, python-mode provides a
+Docker-based testing environment. This is especially useful for contributors
+and developers who want to test the plugin with different Python versions.
+
+## Quick Start
+
+```bash
+# Run tests with default Python version (3.13.0)
+./scripts/user/run-tests-docker.sh
+
+# Run tests with specific Python version
+./scripts/user/run-tests-docker.sh 3.11
+
+# Run tests with all supported Python versions
+./scripts/user/test-all-python-versions.sh

+
+## Supported Python Versions
+
+The Docker environment supports the following Python versions:
+- 3.10.13
+- 3.11.9
+- 3.12.4
+- 3.13.0 (default)
+
+For detailed information about the Docker testing environment, see

 help you that much. Look for our branch with python2-support (old version,
 not maintained anymore) (`last-py2-support`).
 
+## Python 3 Support
+
+`python-mode` supports only Python 3. The project has completely removed Python 2
+support since version 0.11.0. Currently supported Python versions are:
+3.10.13, 3.11.9, 3.12.4, and 3.13.0.
+
+If you need Python 2 support, you can use the legacy `last-py2-support` branch,
+but it is no longer maintained.
+
+## Vim Python Support
+
+Vim [has issues](https://github.com/vim/vim/issues/3585) when compiled with
+both Python 2 and Python 3 support. For best compatibility with python-mode,
+build Vim with only Python 3 support. See
+[this guide](https://github.com/ycm-core/YouCompleteMe/wiki/Building-Vim-from-source)
+for building Vim from source.
+
 ## Symlinks on Windows
 
 Users on Windows OS might need to add `-c core.symlinks=true` switch to
 correctly clone / pull repository. Example: `git clone --recurse-submodules
 https://github.com/python-mode/python-mode -c core.symlinks=true`
 
+## Docker Testing Issues
+
+If you encounter issues with the Docker testing environment:
+
+1. **Build Failures**: Ensure Docker and Docker Compose are properly installed
+   and up to date. The Dockerfile requires Ubuntu 24.04 packages.
+
+2. **Python Version Issues**: Verify that the requested Python version is
+   supported (3.10.13, 3.11.9, 3.12.4, 3.13.0). Use the major.minor format
+   (e.g., `3.11`) when specifying versions.
+
+3. **Vim Build Issues**: The Docker environment builds Vim from source with
+   Python support for each version. Ensure sufficient disk space and memory
+   for the build process.
+
+4. **Test Failures**: If tests fail in Docker but pass locally, check that
+   all git submodules are properly initialized and the correct Python version
+   is active.
+
+For detailed troubleshooting, see [README-Docker.md](README-Docker.md).

+- **run_tests.sh** - Run Vader test suite using Docker Compose
+- **test-all-python-versions.sh** - Test against all supported Python versions
+
+## Test Execution Paths
+
+### Local Development (Docker)
+
+For local development, use Docker Compose to run tests in a consistent environment:
+
+```bash
+# Test with default Python version (3.11)
+./scripts/user/run-tests-docker.sh
+
+# Test with specific Python version
+./scripts/user/run-tests-docker.sh 3.11
+
+# Test all Python versions
+./scripts/user/test-all-python-versions.sh
+
+# Run Vader tests using docker compose
+./scripts/user/run_tests.sh
+
+# Or directly with docker compose
+docker compose run --rm python-mode-tests
+```
+
+### CI/CD (Direct Execution)
+
+In GitHub Actions, tests run directly without Docker for faster execution:
+
+- Uses `scripts/cicd/run_vader_tests_direct.sh`
+- Automatically called by `.github/workflows/test.yml`
+- No Docker build/pull overhead
+- Same test coverage as local Docker tests
+
+## Adding New Tests
+
+To add new tests, simply create a new `.vader` file in `tests/vader/`. Both local Docker and CI test runners will automatically discover and run it.
