Pre-commit Pipeline Setup - Complete!

✅ Successfully Configured

We've set up a comprehensive pre-commit pipeline for Bury with automated quality checks.

What Was Added

1. Pre-commit Configuration (.pre-commit-config.yaml)

Automatically runs before every commit:

  • ✅ Format code - cargo fmt
  • ✅ Lint code - cargo clippy (strict mode, warnings = errors)
  • ✅ Check compilation - cargo check
  • ✅ Run tests - cargo test
  • ✅ Complexity analysis - pmat (non-blocking)
  • ✅ Standard checks - trailing whitespace, YAML/TOML validation, etc.

2. Makefile

Easy-to-use development commands:

make help              # Show all targets
make fmt               # Format code
make lint              # Lint with clippy
make check             # Check compilation
make test              # Run tests
make complexity        # Analyze complexity
make all               # Run all checks
make ci                # Run full CI pipeline
make pre-commit-run    # Run pre-commit manually

3. GitHub Actions CI (.github/workflows/ci.yml)

Automated CI on every push/PR:

  • ✅ Format check
  • ✅ Clippy lint (strict)
  • ✅ Compilation check
  • ✅ Unit tests (Ubuntu, macOS, Windows)
  • ✅ Multiple Rust versions (stable, nightly)
  • ✅ Code coverage (with tarpaulin)
  • ✅ Complexity analysis (pmat)
  • ✅ Release builds

4. Setup Script (scripts/setup.sh)

One-command developer onboarding:

./scripts/setup.sh

Installs:

  • Rust components (rustfmt, clippy)
  • pmat (complexity analyzer)
  • pre-commit hooks

5. Development Guide (DEVELOPMENT.md)

Complete documentation for:

  • Development workflow
  • Pre-commit hooks usage
  • CI/CD pipeline
  • Troubleshooting
  • Code style guidelines

Usage

For New Contributors

# Setup environment
git clone https://github.com/paolorechia/bury
cd bury
./scripts/setup.sh

# Develop
make fmt               # Format before committing
make all               # Run all checks
git commit -m "..."    # Pre-commit runs automatically

For Daily Development

# Quick format
make fmt

# Full check before commit
make all

# Run specific check
make lint
make test

Running Pre-commit Manually

# Run on all files
pre-commit run --all-files

# Run specific hook
pre-commit run cargo-fmt --all-files

# Skip hooks (not recommended)
git commit --no-verify

What Gets Checked

On Every Commit (Pre-commit)

  1. Formatting - Code must be properly formatted
  2. Linting - No clippy warnings allowed
  3. Compilation - Code must compile
  4. Tests - All tests must pass
  5. Complexity - Warning if functions are too complex

On Every Push (GitHub Actions)

All of the above PLUS:

  • Multi-platform testing (Linux, macOS, Windows)
  • Multiple Rust versions (stable, nightly)
  • Code coverage reporting
  • Release build verification

Code Quality Improvements Made

Fixed Issues

  1. ✅ Removed unused parser fields in PythonParser and TypeScriptParser
  2. ✅ Fixed useless_format! warnings in markdown reporter
  3. ✅ Fixed len() >= 1 to !is_empty() in tests
  4. ✅ Fixed scanner test to properly create temporary files

Current Status

  • ✅ 0 clippy warnings (strict mode)
  • ✅ All tests passing (8/8)
  • ✅ Code formatted (rustfmt)
  • ✅ Compilation clean

CI/CD Status

GitHub Actions will now run on every:

  • Push to main
  • Pull request to main

View runs at: https://github.com/paolorechia/bury/actions

Benefits

For Maintainers

  • ✅ Consistent code quality
  • ✅ Catch issues before merge
  • ✅ Automated testing across platforms
  • ✅ Easy contributor onboarding

For Contributors

  • ✅ Clear guidelines (DEVELOPMENT.md)
  • ✅ Automated formatting (no debates)
  • ✅ Immediate feedback (pre-commit)
  • ✅ Confidence in changes (CI)

Future Enhancements

Potential additions:

  • Benchmarking (cargo bench)
  • Security audits (cargo audit)
  • Dependency updates (dependabot)
  • Release automation
  • Performance regression detection

Conclusion

Bury now has production-grade quality automation:

  • Pre-commit hooks prevent bad commits
  • CI ensures cross-platform compatibility
  • Makefile simplifies common tasks
  • Documentation guides contributors

The pipeline works perfectly and all checks pass! ✨

Next time a commit is made, pre-commit will automatically run all checks!
