About:
fades is a command-line tool that automatically manages Python virtual environments for scripts and applications. It creates and maintains isolated environments based on import statements or explicit requirements, eliminating manual venv setup. The tool ensures dependencies are present and up-to-date, streamlining script execution across different systems.

Key Features:

Automatic virtualenv creation and management
Dependency detection from import statements
Isolated environment handling for each script
Support for requirements files and PyPI packages
No manual activation needed

Use Cases:

Running Python scripts with automatic dependency resolution
Developing quick prototypes without manual venv setup
Sharing scripts that automatically handle their own dependencies
Automated testing and CI/CD pipelines

Alternatives:

pipenv – More comprehensive but heavier; requires explicit environment management
poetry – Focuses on project packaging and dependency resolution with lock files
virtualenv – Manual environment creation without automatic dependency detection
