# Setup Summary

## ✅ Environment Setup Complete!

Your `schema-sentinel` project is now set up with modern Python tooling using `uv`.

## What Was Done

### 1. Package Configuration
- ✅ Created `pyproject.toml` with modern packaging configuration
- ✅ Defined all dependencies (SQLAlchemy, Snowflake, Pandas, etc.)
- ✅ Added optional dependency groups for development and Jupyter
- ✅ Configured Ruff for linting and formatting
- ✅ Configured pytest for testing
- ✅ Configured mypy for type checking

### 2. Development Tools
- ✅ Installed `uv` - fast Python package manager
- ✅ Created virtual environment in `.venv/`
- ✅ Installed all project dependencies
- ✅ Created `Makefile` with common commands
- ✅ Created `setup.sh` for quick environment setup

### 3. Documentation
- ✅ Created `README.md` with project overview and setup instructions
- ✅ Created `DEVELOPMENT.md` with detailed development guide
- ✅ Updated `.gitignore` for Python and uv-specific files

### 4. VS Code Configuration
- ✅ Configured Python interpreter (`.venv/bin/python`)
- ✅ Set up Ruff for formatting and linting
- ✅ Configured pytest for testing
- ✅ Added debug configurations
- ✅ Recommended useful extensions

## Installed Packages

## Quick Start Commands

```bash
# Activate the environment
source .venv/bin/activate

# Run tests
pytest

# Format code
ruff format .

# Lint code
ruff check .

# Start Jupyter Lab
jupyter lab

# See all available commands
make help
```

## Project Status

The project is now ready for development! The environment is configured with:
- Python 3.13.11
- All dependencies installed
- Development tools ready
- VS Code properly configured

## Next Steps

1. **Explore the codebase**: Review existing modules in `schema_sentinel/`
2. **Set up database connections**: Configure your Snowflake credentials
3. **Run existing notebooks**: Check the Jupyter notebooks to understand the workflow
4. **Add tests**: Create test files in `tests/` directory
5. **Modernize code**: Update code to use modern Python features (type hints, etc.)
6. **Documentation**: Add docstrings and improve documentation

## Environment Information

- **Virtual Environment**: `/home/igladyshev/projects/schema-sentinel/.venv/`
- **Python Version**: 3.13.11
- **Package Manager**: uv 0.9.28
- **Total Packages**: 150 installed

## Useful Commands

```bash
# Update all dependencies
uv pip install --upgrade -e ".[dev,jupyter]"

# Check for outdated packages
uv pip list --outdated

# Add a new dependency
uv pip install <package-name>
# Then update pyproject.toml manually

# Clean up build artifacts
make clean

# Run with coverage
pytest --cov=schema_sentinel --cov-report=html

# View coverage report
open htmlcov/index.html  # macOS
xdg-open htmlcov/index.html  # Linux
```

## Troubleshooting

If you need to recreate the environment:

```bash
# Remove existing environment
rm -rf .venv

# Recreate and install
./setup.sh

# Or manually
uv venv
source .venv/bin/activate
uv pip install -e ".[dev,jupyter]"
```
