From 095f0f2dc9a31b09800ebcad8d5c4c5011d244eb Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 29 Jan 2026 03:01:29 +0000 Subject: [PATCH 1/4] Modernize project for Python 3.10+ with modern tooling This is a comprehensive modernization of the pyMultiChange project: **Major Changes:** - Migrated from setup.py to Poetry for package management - Updated codebase to require Python 3.10+ - Added Pydantic v2 for robust input/output validation - Configured netlib as direct GitHub dependency - Removed all Python 2 compatibility code **Testing & CI/CD:** - Removed Travis CI configuration - Added GitHub Actions workflow with multi-version testing (3.10, 3.11, 3.12) - Implemented comprehensive pytest test suite with fixtures - Added test coverage reporting - Tests for Pydantic models and main application logic **Code Quality:** - Configured Ruff for fast, modern linting - Added Pylint configuration for code quality checks - Set up MyPy for static type checking - Added type hints throughout codebase - Replaced bare except clauses with proper error handling - Modernized imports (removed __future__ imports) **Developer Experience:** - Added Makefile for common development tasks - Created comprehensive README with examples and documentation - Added py.typed marker for type checking support - Included GitHub issue and PR templates - Improved logging with proper configuration **Code Structure:** - Created pymultichange package with proper structure - Separated concerns: models.py for Pydantic models - Modernized multi_change.py with type hints and better error handling - Used pathlib instead of os.path - Proper use of queue module (no Python 2/3 compatibility hacks) **Breaking Changes:** - Minimum Python version is now 3.10 - Script now installed as 'multi-change' command via Poetry - Old bin/multi_change.py and setup.py removed https://claude.ai/code/session_01T84i3Yc4JoHK2ydKUcYm8P --- .github/ISSUE_TEMPLATE/bug_report.md | 32 +++ .github/ISSUE_TEMPLATE/feature_request.md | 19 ++ .github/PULL_REQUEST_TEMPLATE.md | 37 +++ .github/workflows/ci.yml | 144 +++++++++++ .gitignore | 82 ++++++- .pylintrc | 46 ++++ .ruff.toml | 34 +++ .travis.yml | 15 -- Makefile | 40 +++ README.md | 270 ++++++++++++++++++--- bin/multi_change.py | 224 ----------------- mypy.ini | 21 ++ pymultichange/__init__.py | 5 + pymultichange/models.py | 64 +++++ pymultichange/multi_change.py | 283 ++++++++++++++++++++++ pymultichange/py.typed | 0 pyproject.toml | 123 ++++++++++ setup.py | 12 - tests/__init__.py | 1 + tests/conftest.py | 31 +++ tests/test_models.py | 161 ++++++++++++ tests/test_multi_change.py | 164 +++++++++++++ 22 files changed, 1517 insertions(+), 291 deletions(-) create mode 100644 .github/ISSUE_TEMPLATE/bug_report.md create mode 100644 .github/ISSUE_TEMPLATE/feature_request.md create mode 100644 .github/PULL_REQUEST_TEMPLATE.md create mode 100644 .github/workflows/ci.yml create mode 100644 .pylintrc create mode 100644 .ruff.toml delete mode 100644 .travis.yml create mode 100644 Makefile delete mode 100755 bin/multi_change.py create mode 100644 mypy.ini create mode 100644 pymultichange/__init__.py create mode 100644 pymultichange/models.py create mode 100644 pymultichange/multi_change.py create mode 100644 pymultichange/py.typed create mode 100644 pyproject.toml delete mode 100755 setup.py create mode 100644 tests/__init__.py create mode 100644 tests/conftest.py create mode 100644 tests/test_models.py create mode 100644 tests/test_multi_change.py diff --git a/.github/ISSUE_TEMPLATE/bug_report.md b/.github/ISSUE_TEMPLATE/bug_report.md new file mode 100644 index 0000000..fb7cc8f --- /dev/null +++ b/.github/ISSUE_TEMPLATE/bug_report.md @@ -0,0 +1,32 @@ +--- +name: Bug report +about: Create a report to help us improve +title: '[BUG] ' +labels: bug +assignees: '' +--- + +## Describe the bug +A clear and concise description of what the bug is. + +## To Reproduce +Steps to reproduce the behavior: +1.

[PATCH 2/4] Fix linting errors for Ruff compliance - Replace Optional[X] with X | None syntax for Python 3.10+ - Remove unused imports (NoReturn, Optional, Generator) - Fix import ordering to follow Ruff/isort conventions - Separate standard library, third-party, and local imports All changes ensure compatibility with Ruff linter configuration and maintain Python 3.10+ modern syntax requirements.
