🔄 Latest Updates

Flake8 Errors Fixed & Code Refactoring (Latest Commit):

• Refactored complex functions in leibnet.py to reduce cyclomatic complexity:
  • LeibNet.__init__ (C901: 13 → 8) - Extracted helper methods for network interface, node processing, and initialization
  • LeibNet.assemble (C901: 23 → 6) - Extracted 5 helper methods for validation, graph building, boundary identification, execution order, and scale computation
  • LeibNet.to_mermaid (C901: 19 → 5) - Extracted helper methods for separators, shapes, and different rendering modes
• Fixed unused imports across multiple files:
  • Removed unused torch.device import from leibnet.py
  • Removed unused torch import from conv_resample_node.py
  • Removed unused Tuple import from resample_node.py
  • Cleaned up test imports (MagicMock, numpy, torch where unused)
• Fixed intentionally unused variables with proper noqa comments in local_learning.py
• Fixed whitespace issues (W293) by running black
• Fixed missing whitespace after comma in additive_attention_gate_node.py
• Updated .flake8 configuration:
  • Reduced max-complexity from 25 to 15 (after refactoring)
  • Re-enabled C901 complexity checks (was previously ignored)
  • Added per-file ignores for test files and inherently complex initialization functions
  • Kept E501, W605 ignored (Black handles line length, docstring escape sequences)
• All 228 tests passing ✅
• Code coverage improved to 91.03% (from 90.51%)

Previous Updates:

• Applied black formatting to all files (excluding benchmark.py which has IPython magic commands)
• Applied isort import sorting to all files
• Fixed circular import issue in src/leibnetz/nodes/__init__.py by ensuring Node is imported first
• Modified format job to run black and isort without --check flags (actually formats files)
• Added automatic commit step to push formatting changes back to the PR branch
• Removed duplicate installation of isort and flake8 (already in requirements-dev.txt)
• Moved import re to top of file with other imports (follows Python conventions)
• Fixed date-released from 2025-10-29 to 2024-10-29
• Added Python version classifiers for 3.10, 3.11, and 3.12 to document official support

🔧 CI/CD Pipeline Architecture

Job Flow:

trigger → [format] → [test, mypy] → [tag-release] → [publish]
                ↓         ↓
              parallel   parallel

Format Job:

• Runs: Ubuntu latest, Python 3.x
• Tasks:
  • flake8 linting (validation only)
  • black formatting (auto-fixes and commits)
  • isort import sorting (auto-fixes and commits)
  • Auto-commits changes to PR branch with [skip ci] flag

Test Job (Matrix):

• Platforms: Ubuntu, Windows, macOS
• Python versions: 3.10, 3.11, 3.12 (9 combinations)
• Coverage: Codecov integration

MyPy Job:

• Runs in parallel with tests
• Python 3.10 type checking

Tag-Release Job:

• Triggers: On main branch push (not [skip ci])
• Reads version from CITATION.cff
• Creates git tag and GitHub release

Publish Job:

• Triggers: After successful tag-release
• Builds sdist and wheel
• Publishes to PyPI (requires PYPI_API_TOKEN secret)

Concurrency:

• Cancel in-progress runs for same branch
• Saves CI resources

🛠️ Development Tools

Makefile Commands:

make help          # Show all available commands
make install-dev   # Install package with dev dependencies
make test          # Run tests
make test-cov      # Run tests with coverage report
make lint          # Run flake8 linting
make format        # Format code (black + isort)
make type-check    # Run mypy type checking
make clean         # Clean build artifacts
make build         # Build package
make check-all     # Run all checks (lint + type + test)
make pre-commit    # Run pre-commit hooks
make version       # Show package version

Pre-commit Hooks:

• Standard checks: trailing-whitespace, end-of-file-fixer, check-yaml, check-toml
• Formatters: black, isort
• Linters: flake8
• Custom: update-version (main branch only)

Tool Configurations in pyproject.toml:

• pytest: Test options, markers, coverage settings
• coverage: Source paths, omit patterns, report settings
• black: Line length 88, target Python 3.10-3.12
• isort: Black profile, known first-party packages
• mypy: Type checking options, ignore patterns

📋 Next Steps for Repository Maintainers

1. Set GitHub Secrets (for automated publishing):

   • CODECOV_TOKEN - For coverage reporting (optional, public repos work without)
   • PYPI_API_TOKEN - For automated PyPI publishing (if desired)

2. Install Pre-commit Hooks (optional for contributors):

   make pre-commit-install

3. Update CITATION.cff when making releases:

   • Version will auto-update on main branch commits
   • Manual updates supported too

4. Use Makefile Commands for local development:

   make install-dev  # First time setup
   make format       # Before committing
   make check-all    # Before pushing

5. Note on Auto-formatting:

   • The CI will automatically format code with black and isort
   • Formatting changes are committed back to PR branches with [skip ci] flag
   • Reduces friction for contributors who forget to format locally

---

✅ Minimal Changes Approach

All changes are non-breaking and improve code quality:

• ✅ Existing functionality unchanged (refactored for readability)
• ✅ All tests still pass (228 passed)
• ✅ Coverage improved (90.51% → 91.03%)
• ✅ No dependencies removed
• ✅ Backward compatible
• ✅ Code complexity significantly reduced

pyproject.toml:1

• The regex pattern has invalid syntax - it's missing the opening quote. Should be 'if name == "main":' or 'if name == .main.:'.

.pre-commit-hooks/update-version.py:1

• The pre-commit hook uses 'language: system' which requires the script to be directly executable in the system's Python environment. However, the script imports standard library modules (re, datetime, os, subprocess, sys) that should be available, but this approach is fragile. Consider using 'language: python' with 'additional_dependencies: []' to ensure the hook runs in a controlled environment, or document that users must have Python 3 available in their PATH.

@copilot Please fix black and flake8 formatting, and ensure all tests are passing.

@copilot Please fix black and flake8 formatting, and ensure all tests are passing.

Fixed in commit 15ca629. Applied black and isort formatting to all files. Fixed a circular import issue in src/leibnetz/nodes/__init__.py by ensuring Node is imported first and adding isort directives to prevent future reordering. All 228 tests are passing ✅

@copilot Many flake8 errors remain - address them. Adjust flake8 linting settings in pyproject.toml if they conflict with black formatting rules.

@copilot Many flake8 errors remain - address them. Adjust flake8 linting settings in pyproject.toml if they conflict with black formatting rules.

Fixed in commit c34c706. Addressed all flake8 errors by:

1. Refactored complex functions to reduce cyclomatic complexity by 60%:

   • LeibNet.__init__: Extracted helper methods for network interface, node processing, and weight initialization
   • LeibNet.assemble: Broke down into 5 focused helper methods
   • LeibNet.to_mermaid: Extracted helper methods for different rendering modes

2. Fixed unused imports across src and tests (removed torch, numpy, Tuple, MagicMock where not used)

3. Updated .flake8 configuration:

   • Re-enabled C901 complexity checks (was previously ignored)
   • Reduced max-complexity from 25 to 15 after refactoring
   • Added per-file ignores for tests and inherently complex initialization functions
   • E501 and W605 remain ignored per Black compatibility guidelines

4. All 228 tests passing with improved coverage (91.03% from 90.51%)
