Installation

pip install pedroasad-attrs-patch

This library contains optional support for Numpy arrays in attrs frozen classes. It may be installed by passing the [numpy] option when installing.

Usage

It acts as a drop-in replacement to attrs. The example below shows how to use it, including all currently existing improvements.

from attrs_patch import attr


@attr.autodoc
@attr.s(frozen=True)
class SomeClass:
    a = attr.ib(metadata={"help": "An immutable numpy array."}, 
                converter=attr.frozen_numpy_array,
                hash=False)
    b = attr.ib(metadata={"help": "A positive integer."},
                converter=int,
                validator=attr.validators.positive)
    c = attr.ib(metadata={"help": "A non-zero integer."}, 
                converter=int,
                validator=attr.validators.nonzero)
