attrs v16.3.0 Release Notes

Release Date: 2016-11-24 // over 7 years ago

  • 🔄 Changes: ^

    • 📇 Attributes now can have user-defined metadata which greatly improves attrs's extensibility. #96 <https://github.com/python-attrs/attrs/pull/96>_
    • Allow for a __attrs_post_init__() method that -- if defined -- will get called at the end of the attrs-generated __init__() method. #111 <https://github.com/python-attrs/attrs/pull/111>_
    • Added @attr.s(str=True) that will optionally create a __str__() method that is identical to __repr__(). This is mainly useful with Exception\ s and other classes that rely on a useful __str__() implementation but overwrite the default one through a poor own one. Default Python class behavior is to use __repr__() as __str__() anyways.

    If you tried using attrs with Exception\ s and were puzzled by the tracebacks: this option is for you.

    • __name__ is no longer overwritten with __qualname__ for attr.s(slots=True) classes. #99 <https://github.com/python-attrs/attrs/issues/99>_
