| """Auxlib is an auxiliary library to the python standard library. |
| |
| The aim is to provide core generic features for app development in python. Auxlib fills in some |
| python stdlib gaps much like `pytoolz <https://github.com/pytoolz/>`_ has for functional |
| programming, `pyrsistent <https://github.com/tobgu/pyrsistent/>`_ has for data structures, or |
| `boltons <https://github.com/mahmoud/boltons/>`_ has generally. |
| |
| Major areas addressed include: |
| - :ref:`packaging`: package versioning, with a clean and less invasive alternative to |
| versioneer |
| - :ref:`entity`: robust base class for type-enforced data models and transfer objects |
| - :ref:`type_coercion`: intelligent type coercion utilities |
| - :ref:`configuration`: a map implementation designed specifically to hold application |
| configuration and context information |
| - :ref:`factory`: factory pattern implementation |
| - :ref:`path`: file path utilities especially helpful when working with various python |
| package formats |
| - :ref:`logz`: logging initialization routines to simplify python logging setup |
| - :ref:`crypt`: simple, but correct, pycrypto wrapper |
| |
| [2021-11-09] Our version of auxlib has deviated from the upstream project by a significant amount |
| (especially compared with the other vendored packages). Further, the upstream project has low |
| popularity and is no longer actively maintained. Consequently it was decided to absorb, refactor, |
| and replace auxlib. As a first step of this process we moved conda._vendor.auxlib to conda.auxlib. |
