| 1 | +# Hatch Tooling Requirements |
| 2 | + |
| 3 | +## Primary Development Tool |
| 4 | + |
| 5 | +**CRITICAL:** This project uses **Hatch** as its primary development and build tool. All development workflows, dependency management, testing, and build operations MUST use Hatch unless technically impossible. |
| 6 | + |
| 7 | +## Why Hatch? |
| 8 | + |
| 9 | +Hatch is the modern Python project manager that provides: |
| 10 | +- Unified environment management |
| 11 | +- Reproducible builds |
| 12 | +- Integrated testing workflows |
| 13 | +- Standardized project structure |
| 14 | +- PEP 517/518 compliance |
| 15 | + |
| 16 | +## Hatch Command Reference |
| 17 | + |
| 18 | +### Environment Management |
| 19 | + |
| 20 | +**Install dependencies and set up environment:** |
| 21 | +```bash |
| 22 | +hatch env create |
| 23 | +``` |
| 24 | + |
| 25 | +**Activate the default environment:** |
| 26 | +```bash |
| 27 | +hatch shell |
| 28 | +``` |
| 29 | + |
| 30 | +**Run commands in the environment without activation:** |
| 31 | +```bash |
| 32 | +hatch run <command> |
| 33 | +``` |
| 34 | + |
| 35 | +**List all environments:** |
| 36 | +```bash |
| 37 | +hatch env show |
| 38 | +``` |
| 39 | + |
| 40 | +**Remove an environment:** |
| 41 | +```bash |
| 42 | +hatch env remove <env-name> |
| 43 | +``` |
| 44 | + |
| 45 | +### Dependency Management |
| 46 | + |
| 47 | +**Add a new dependency:** |
| 48 | +```bash |
| 49 | +# Edit pyproject.toml [project.dependencies] section manually |
| 50 | +# Then sync the environment |
| 51 | +hatch env create |
| 52 | +``` |
| 53 | + |
| 54 | +**Add a development dependency:** |
| 55 | +```bash |
| 56 | +# Edit pyproject.toml [tool.hatch.envs.default] section manually |
| 57 | +# Then sync the environment |
| 58 | +hatch env create |
| 59 | +``` |
| 60 | + |

| 187 | +## Development Workflow with Hatch |
| 188 | + |
| 189 | +### Initial Setup |
| 190 | +```bash |
| 191 | +# Clone the repository |
| 192 | +git clone <repository-url> |
| 193 | +cd python_janus_client |
| 194 | + |
| 195 | +# Create and activate environment |
| 196 | +hatch env create |
| 197 | +hatch shell |
| 198 | + |
| 199 | +# Verify installation |
| 200 | +hatch run python -c "import janus_client; print(janus_client.__version__)" |
| 201 | +``` |
| 202 | + |
| 203 | +### Daily Development |
| 204 | +```bash |
| 205 | +# Activate environment |
| 206 | +hatch shell |
| 207 | + |
| 208 | +# Run tests during development |
| 209 | +hatch run pytest tests/ |
| 210 | + |
| 211 | +# Check code quality |
| 212 | +hatch run lint:check |
| 213 | + |
| 214 | +# Format code |
| 215 | +hatch run lint:fmt |
| 216 | +``` |
| 217 | + |
| 218 | +### Before Committing |
| 219 | +```bash |
| 220 | +# Run full test suite |
| 221 | +hatch run test |
| 222 | + |
| 223 | +# Check coverage |
| 224 | +hatch run cov |
| 225 | + |
| 226 | +# Run linting |
| 227 | +hatch run lint:check |
| 228 | + |
| 229 | +# Run type checking |
| 230 | +hatch run lint:typing |
| 231 | + |
| 232 | +# Build documentation |
| 233 | +hatch run docs:build |
| 234 | +``` |
| 235 | + |
| 236 | +### Adding New Dependencies |
| 237 | +```bash |
| 238 | +# 1. Edit pyproject.toml to add dependency |
| 239 | +# 2. Recreate environment |
| 240 | +hatch env prune |
| 241 | +hatch env create |
| 242 | + |
| 243 | +# 3. Verify dependency is installed |
| 244 | +hatch run python -c "import <new_package>" |
| 245 | +``` |
| 246 | + |
| 247 | +## When NOT to Use Hatch |
| 248 | + |
| 249 | +Hatch should be used for all development tasks. However, in rare cases where Hatch cannot be used: |
| 250 | + |
| 251 | +1. **CI/CD Constraints:** If the CI/CD platform doesn't support Hatch, use pip with requirements files generated from pyproject.toml |
| 252 | +2. **Legacy System Compatibility:** If deploying to systems that cannot run Hatch |
| 253 | +3. **Docker Builds:** In minimal Docker images, pip installation from wheel may be preferred |
| 254 | + |
| 255 | +In these cases, document the reason and provide alternative commands. |
| 256 | + |
| 257 | +## Migration from Poetry |
| 258 | + |
| 259 | +This project previously used Poetry. If you encounter Poetry commands in documentation or scripts: |
| 260 | + |
| 261 | +| Poetry Command | Hatch Equivalent | |
| 262 | +|----------------|------------------| |
| 263 | +| `poetry install` | `hatch env create` | |
| 264 | +| `poetry shell` | `hatch shell` | |
| 265 | +| `poetry add <package>` | Edit pyproject.toml + `hatch env create` | |
| 266 | +| `poetry run <command>` | `hatch run <command>` | |
| 267 | +| `poetry build` | `hatch build` | |
| 268 | +| `poetry publish` | `hatch publish` | |
| 269 | +| `poetry version` | `hatch version` | |
| 270 | +| `poetry run pytest` | `hatch run pytest` | |
| 271 | +| `poetry run flake8` | `hatch run lint:check` | |
| 272 | + |
| 273 | +## Environment Configuration |
| 274 | + |
| 275 | +Hatch environments are configured in `pyproject.toml` under `[tool.hatch.envs]`. The project uses: |
| 276 | + |
| 277 | +- **default:** Main development environment with all dependencies |
| 278 | +- **test:** Testing environment with pytest and coverage |
| 279 | +- **lint:** Linting environment with flake8, black, isort, mypy |
| 280 | +- **docs:** Documentation environment with mkdocs |
| 281 | + |
| 282 | +## Best Practices |
| 283 | + |
| 284 | +1. **Always use Hatch commands:** Don't use pip directly in the project directory |
| 285 | +2. **Keep pyproject.toml updated:** All dependencies must be declared in pyproject.toml |
| 286 | +3. **Use environment-specific commands:** Use `hatch run <env>:<script>` for specific environments |
| 287 | +4. **Regenerate environments after changes:** Run `hatch env prune && hatch env create` after modifying dependencies |
| 288 | +5. **Document Hatch usage:** When adding new scripts or workflows, document the Hatch commands |
| 289 | + |
| 290 | +## Troubleshooting |
| 291 | + |
| 292 | +### Environment Issues |
| 293 | +```bash |
| 294 | +# Remove all environments and start fresh |
| 295 | +hatch env prune |
| 296 | +hatch env create |
| 297 | +``` |
| 298 | + |
| 299 | +### Dependency Conflicts |
| 300 | +```bash |
| 301 | +# Check environment details |
| 302 | +hatch env show |
| 303 | + |
| 304 | +# Recreate specific environment |
| 305 | +hatch env remove <env-name> |
| 306 | +hatch env create <env-name> |
| 307 | +``` |
| 308 | + |
| 309 | +### Command Not Found |
| 310 | +```bash |
| 311 | +# Ensure you're in the project directory |
| 312 | +cd /path/to/python_janus_client |
| 313 | + |
| 314 | +# Verify Hatch is installed |
| 315 | +hatch --version |
| 316 | + |
| 317 | +# If not installed, install Hatch |
| 318 | +pip install hatch |
| 319 | +``` |
| 320 | + |
| 321 | +## Summary |
| 322 | + |
| 323 | +**Remember:** Use Hatch for ALL development tasks. This ensures consistency, reproducibility, and adherence to modern Python packaging standards. Only deviate from Hatch when technically impossible, and document the reason clearly. |
