prybar: Create temporary pkg_resources entry points at runtime

A Python library to temporarily define pkg_resources entry points at runtime. The primary use case is testing code which works with entry points.

Installing

$ pip install prybar

prybar requires Python 3.6 or greater.

Usage

>>> import prybar
>>> from pkg_resources import iter_entry_points
>>> # Entry point doesn't exist
>>> list(iter_entry_points('example.hash_types', 'sha256'))
[]
>>> # With prybar's context manager we can create entry points temporarily
>>> with prybar.dynamic_entrypoint('example.hash_types',
...                                name='sha256', module='hashlib'):
...     hash = next(iter_entry_points('example.hash_types', 'sha256')).load()
...     hash(b'foo').hexdigest()[:6]
'2c26b4'
>>> # And it's gone again
>>> list(iter_entry_points('example.hash_types', 'sha256'))
[]
