Python package to dynamically read setup configurations and load dependencies.
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 and PyInstaller, Pyppyn can help you out.
Pyppyn can be used in scripts or using the CLI. Either way, it can be installed easily.
$ pip install pyppyn
Pyppyn will display help in typical fashion.
$ 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.

This is a sample usage of Pyppyn from a Python script.
import pyppyn # Create an instance p = pyppyn.ConfigRep(setup_path="tests/minipippy") # Load config, install dependencies and import a module from the package p.process_config() print("Package requires:", p.get_required())

This module is named in honor of Pippin, a companion, friend, Bichon Frise-Shih Tzu mix. He passed away on March 30, 2018 at the age of 12 after a battle with diabetes, blindness, deafness, and loss of smell. Pleasant to the end, he was a great, great dog.
