Feu - Python Package and Version Manager

0.6.2 · active · verified Mon Apr 13

Feu (French word for "fire" 🔥) is a lightweight Python library designed to help manage Python packages and their versions across different Python environments. It offers key features such as checking package availability, performing version-aware installations, and smart version resolution. Currently at version 0.6.2, it is in active development with no guarantees of API stability before a 1.0.0 release.

Warnings

breaking The API of 'feu' is not guaranteed to be stable and is likely to change significantly before a stable 1.0.0 release. Upgrading to newer pre-1.0.0 versions may introduce breaking changes to existing code.
Fix: Review release notes for each new version and adapt your code as necessary. Consider pinning minor versions or specific versions to mitigate unexpected breakage.
gotcha As a library in early development (pre-1.0.0), 'feu' may have rapidly evolving functionality, incomplete features, or undocumented behaviors. Relying on current features without careful testing might lead to issues in future updates.
Fix: Thoroughly test your application when integrating or upgrading 'feu'. Monitor the project's development for updates on stability and new features. Contribute feedback if you encounter unexpected behavior.

Quickstart

This example demonstrates how to check for package availability and retrieve its version using `feu`. It also shows how to import `find_closest_version` for more advanced version resolution, although the specific implementation details for finding the 'closest' version are internal to the library or require a configured registry.

from feu import is_package_available, get_package_version
from feu.package import find_closest_version

# Check if a package is available
if is_package_available("numpy"):
    version = get_package_version("numpy")
    print(f"NumPy is installed with version: {version}")
else:
    print("NumPy is not installed.")

# Example of finding a compatible version (logic might vary for actual use)
# This demonstrates the import, a real use case would involve a registry or specific version constraints.
try:
    # Note: 'find_closest_version' would typically rely on a pre-defined registry or extensive lookup logic
    # For this quickstart, it's shown as an imported function, assuming it has internal logic.
    closest_np_version = find_closest_version("numpy", "1.20")
    print(f"Closest NumPy version to 1.20 found: {closest_np_version}")
except Exception as e:
    print(f"Could not find closest version for numpy 1.20: {e}")
