From 9ea7c8cfdaaad72970fdada01cc79cf780658d49 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 19 Jan 2026 20:56:08 +0000 Subject: [PATCH 1/5] Add Python and YAML linting to CI pipeline (fixes #112) Implements comprehensive code quality tooling using modern, fast linters: **Python Linting:** - Added Ruff for linting and formatting (replaces Black + Flake8 + isort) - Configured in pyproject.toml with sensible defaults: - Line length: 100 characters - Enabled rulesets: pycodestyle, pyflakes, isort, pep8-naming, pyupgrade, flake8-bugbear, flake8-comprehensions, flake8-simplify, flake8-return - Auto-fix enabled for safe violations **YAML Linting:** - Added yamllint for formula YAMLs and workflow files - Configured in .yamllint with project-specific rules: - Line length warnings at 120 characters (allows long formulas) - 2-space indentation (GitHub Actions standard) - Supports truthy values for GH Actions (on/off, yes/no) **CI Integration:** - Updated .github/workflows/test.yml with 3 new steps: 1. Lint Python code with Ruff 2. Check Python formatting with Ruff 3. Lint YAML files with yamllint - Linting runs before tests to fail fast on style issues **Code Fixes:** - Fixed all linting violations in existing code: - Removed unused imports and variables - Fixed import ordering and formatting - Simplified nested if statements - Added proper exception chaining (raise...from) - Applied consistent code formatting - Removed trailing whitespace from YAML files **Dependencies:** - Added ruff>=0.8.0 and yamllint>=1.35.0 to dev dependencies - Updated uv.lock with new dependencies All existing tests pass (156/156).
