Lightweight Python library for robustly validating decorated functions, providing a clean, structured way to ensure they comply with defined conditions.

[📚 The complete documentation is available here.](https://decoguard.readthedocs.io/en/latest/)

## ✨ Features

- **Meta-Decorators**: Easily add validation logic to your decorators and decorator factories.
- **Validator Functions**: Fine-grained validation rules for function signatures and usage.
- **Assertion Utilities**: Reusable assertion helpers for standalone validation.
- **Centralized Validation**: Keep your validation logic clean and maintainable.
- **Clear Error Reporting**: Developer-friendly exceptions for invalid decorator usage.
- **Drop-In Simplicity**: Integrate with existing Python code with minimal changes.

## 🚀 Getting Started

1. **Install decoguard**
   ```bash
   pip install decoguard
   ```
2. **Import and use meta-decorators**
   ```python
   from decoguard.decorators import validate_decorated
   from decoguard.validators import require_params

   @validate_decorated(require_params("x", "y"))
   def my_decorator(func): return func

   @my_decorator
   def correct_usage(x, y): pass

   @my_decorator
   def bad_usage(x): pass # Will raise DecoratorUsageValidationError
   ```

## 💚 CI/CD Pipeline

This project maintains high code quality through automated GitLab CI/CD pipelines that run on every merge request and main branch commit:

### Quality Assurance
- **Code Testing**: Comprehensive test suite using `tox` and `pytest` with coverage reporting
- **Code Formatting**: Automated formatting with `black` and import sorting with `isort`
- **Code Style**: Style checking with `flake8` following project standards
- **Type Checking**: Static type analysis using `mypy` for type safety
- **Security Scanning**:
  - Dependency vulnerability checks with `safety`
  - Code security analysis with `bandit` (excluding test files)

### Deployment
- **Automated Building**: Package building and integrity validation
- **PyPI Deployment**: Automatic deployment to PyPI on tagged releases
- **Manual Release**: Production deployments require manual approval for safety

The same quality checks can be run locally using the included `format_and_check.py` script.
