Latest commit 863e96f Mar 6, 2013


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.

How to Install

Installing using pip:

$ pip install stallion

Upgrading using pip:

$ pip install --upgrade stallion

or using easy install:

Installing using easy_install:

$ easy_install stallion

Upgrading using easy_install:

$ easy_install -U stallion

Installing as a systemd service

If you're running Linux with systemd installed, you can register Stallion as a service by copying stallion.service and stallion (both in contrib/systemd) to /etc/systemd/system and /etc/conf.d, respectively.

All standard systemd service management commands (e.g. systemctl enable and systemctl start) apply.

Installing as an Upstart service

On Linux systems having Upstart you can set up Stallion as a service easily as follow.

  • copy contrib/upstart/stallion.conf to /etc/init/

  • make a symbolic link for it in /etc/init.d/:

    $ ln -s /etc/init/stallion.conf /etc/init.d/stallion
  • copy contrib/upstart/stallion to /etc/default/

Service management

$ sudo start stallion
$ sudo stop stallion
$ sudo status stallion


$ sudo service stallion start
$ sudo service stallion stop
$ sudo service stallion status

Service customization

You can customize the host and port the stallion service will be listening on by editing the file /etc/default/stallion.

Using Stallion

You only need to call the script (the -w option will automatically open your browser):

$ stallion -w

Using plp

$ plp --help
Stallion - Python List Packages (PLP)

  plp list [--compact] [<filter>]
  plp show <project_name>
  plp check <project_name>
  plp scripts [<filter>]

  plp (-h | --help)
  plp --version

  --compact     Compact list format
  -h --help     Show this screen.
  --version     Show version.

Setting a development environment

Developers can setup a development environment using the "develop" command from setuptools:

$ python develop
$ stallion

HTML, CSS, and JS toolkit from Twitter


Docutils is an open-source text processing system for processing plaintext documentation into useful formats, such as HTML or LaTeX.

Jinja2 (Flask requirement)

The Jinja2 template engine

Werkzeug (Flask requirement)

A flexible WSGI implementation and toolkit

Simplejson (If you use Python 2.5)

Simple, fast, extensible JSON encoder/decoder for Python

docopt (used by plp)

Command-line interface description language

colorama (used by plp)

Cross-platform colored terminal text.

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
