Pyppyn helps you dynamically read setup configurations and load dependencies.
Since pip is excellent at reading setup configurations and loading dependencies, why Pyppyn?
If you need programmatic access to dependency information, for
example, in dynamically creating standalone
applications using GravityBee <https://github.com/plus3it/gravitybee>_ and PyInstaller <http://www.pyinstaller.org>_, Pyppyn can help you out.
Pyppyn can be used in scripts or using the CLI. Either way, it can be installed easily.
.. code-block:: bash
$ pip install pyppyn
Pyppyn will display help in typical fashion.
.. code-block:: bash
$ pyppyn --help
To parse the included test mini Python package (tests/minipippy), with a setup.cfg and setup.py file, and install the required dependencies, you can use this command. This allows you to install dependencies without installing the package.
.. code-block:: bash
$ pyppyn --setup-path tests/minipippy --platform linux -v -a

p = pyppyn.ConfigRep(setup_path="tests/minipippy")
# Load config, install dependencies and import a module from the package
p.process_config()
