Stallion - A Python Package Manager

Download this project as a .zip file Download this project as a tar.gz file


Stallion is a Python Package Manager interface created to provide an "easy-to-use" visual and also a command-line interface for Pythonistas. Today we have many nice distribution utilities like pip, distribute, etc, but we don't have a nice visual approach to inspect current installed packages, show projects metadata, check for PyPI updates, etc.

Global checking feature

  Many people asked for a global version updates checking, now you have this
  feature under the menu "PyPI Repository". This option is going to check
  updates for all your packages. A new icon will appear on the sidebar
  packages menu warning in case of a new available update.

Classifiers refactoring

  The classifiers of the package are now visually different.

Reporting bug

Open an issue in Github with the traceback. To get the traceback, you'll have to run Stallion in debugging mode:

$ stallion -drvi
