argparse2 is a fork of the Python standard library's argparse
module.
The project page and source code are on GitHub.
argparse2 is distributed for free on PyPI.
Project documentation is hosted on Read the Docs.
The purposes of the fork include--
- improving the extensibility of argparse,
- simplifying the code and improving its maintainability, and
- adding features.
We aim to preserve backwards compatibility for the most part. We anticipate breaking backwards compatibility only in the case of warts and "documented bugs."
The main work being done so far is simplifying the code base. Up to this point, all of the test cases in the original CPython implementation continue to pass.
The code in the original argparse module is complicated. Moreover, being part of CPython, the pace of change to the module is slow. This makes major refactorings impractical or not possible. As Guido van Rossum is fond of saying, modules in the standard library have "one foot in the grave."
This project was started to break free of those constraints and breathe new life into argparse. The module was forked from the tip of the CPython tree (Python 3.5.0 alpha 1) on November 27, 2014. See the Summary of Changes section of the documentation for more information.
- Python 3.4 or higher.
