literate-dataclasses 0.0.6

This is a work-in-progress library to add documentation functionality to dataclasses introduced in Python 3.7. The library can be used as a drop-in replacement for the standard dataclasses and can be installed from PyPI.

$ pip install literate_dataclasses

Literate dataclasses modify their own class docstrings and add attribute docs in [Google code style](https://google.github.io/styleguide/pyguide.html) with the goal of removing redundant code. The docs can be written as follows:

from literate_dataclasses import dataclass, field

@dataclass(test_arg = "hello")
class Test:
    """My dataclass

    Some comment.

    Args:
        See dataclass signature.
    """

    x: int = field(default = 42, doc = \
    """Some value x."""
    )

    y: int = field(default = 72, doc = \
    """Some value x."""
    )

    name: int = field(default = 'foo', doc = \
    """The object name.""",
    )

test = Test(x = 5, y = 3)
help(Test)

which will generate the output
