Formats docstrings to follow `PEP 257`_.

.. _`PEP 257`: http://www.python.org/dev/peps/pep-0257/

Features
========

``docformatter`` automatically formats docstrings to follow a subset of the PEP
257 conventions. Below are the relevant items quoted from PEP 257.

- For consistency, always use triple double quotes around docstrings.
- Triple quotes are used even though the string fits on one line.
- Multi-line docstrings consist of a summary line just like a one-line
  docstring, followed by a blank line, followed by a more elaborate
  description.
- Unless the entire docstring fits on a line, place the closing quotes
  on a line by themselves.

``docformatter`` also handles some of the PEP 8 conventions.

- Don't write string literals that rely on significant trailing
  whitespace. Such trailing whitespace is visually indistinguishable
  and some editors (or more recently, reindent.py) will trim them.

``docformatter`` formats docstrings compatible with ``black`` when passed the
``--black`` option.

``docformatter`` formats field lists that use Epytext or Sphinx styles.

See the the full documentation at `read-the-docs`_, especially the
`requirements`_ section for a more detailed discussion of PEP 257 and other
requirements.

.. _requirements: https://docformatter.readthedocs.io/en/latest/requirements.html

Installation
============

From pip::

    $ pip install --upgrade docformatter

Or, if you want to use pyproject.toml to configure docformatter and you're using
Python < 3.11::

    $ pip install --upgrade docformatter[tomli]

With Python >=3.11, ``tomllib`` from the standard library is used.

Or, if you want to use a release candidate (or any other tag)::

    $ pip install git+https://github.com/PyCQA/docformatter.git@<RC_TAG>

Where <RC_TAG> is the release candidate tag you'd like to install.  Release
candidate tags will have the format v1.6.0-rc1  Release candidates will also be
made available as a Github Release.

Example
=======

After running::

    $ docformatter --in-place example.py

this code

.. code-block:: python

    """   Here are some examples.

        This module docstring should be dedented."""


    def launch_rocket():
        """Launch
    the
    rocket. Go colonize space."""


    def factorial(x):
        '''

        Return x factorial.

        This uses math.factorial.

        '''
        import math
        return math.factorial(x)


    def print_factorial(x):
        """Print x factorial"""
        print(factorial(x))


    def main():
        """Main
        function"""
        print_factorial(5)
        if factorial(10):
            launch_rocket()


gets formatted into this

.. code-block:: python

    """Here are some examples.

    This module docstring should be dedented.
    """


    def launch_rocket():
        """Launch the rocket.

        Go colonize space.
        """


    def factorial(x):
        """Return x factorial.

        This uses math.factorial.
        """
        import math
        return math.factorial(x)


    def print_factorial(x):
        """Print x factorial."""
        print(factorial(x))


    def main():
        """Main function."""
        print_factorial(5)
        if factorial(10):
            launch_rocket()
