r"""
Extensions to :mod:`sphinx.ext.autosummary`.

Provides an enhanced version of https://autodocsumm.readthedocs.io/
which respects the autodoc ``member-order`` option.
This can be given for an individual directive, in the
`autodoc_member_order <https://www.sphinx-doc.org/en/master/usage/extensions/autodoc.html#confval-autodoc_member_order>`_
configuration value, or via :confval:`autodocsumm_member_order`.

Also patches :class:`sphinx.ext.autosummary.Autosummary` to fix an issue where
the module name is sometimes duplicated.
I.e. ``foo.bar.baz()`` became ``foo.bar.foo.bar.baz()``, which of course doesn't exist
and created a broken link.


.. versionadded:: 0.7.0

.. versionchanged:: 1.3.0

	Autosummary now selects the appropriate documenter for attributes rather than
	falling back to :class:`~sphinx.ext.autodoc.DataDocumenter`.

.. versionchanged:: 2.13.0

	Also patches :class:`sphinx.ext.autodoc.ModuleDocumenter` to fix an issue where
	``__all__`` is not respected for autosummary tables.



Configuration
--------------

.. latex:vspace:: -20px

.. confval:: autodocsumm_member_order
	:type: :py:obj:`str`
	:default: ``'alphabetical'``

	Determines the sort order of members in ``autodocsumm`` summary tables.
	Valid values are ``'alphabetical'`` and ``'bysource'``.

	Note that for ``'bysource'`` the module must be a Python module with the source code available.

	The member order can also be set on a per-directive basis using the ``:member-order: [order]`` option.
	This applies not only to :rst:dir:`automodule` etc. directives,
	but also to :rst:dir:`automodulesumm` etc. directives.

.. confval:: autosummary_col_type
	:type: :py:obj:`str`
	:default: ``'\X'``

	The LaTeX column type to use for autosummary tables.

	Custom columns can be defined in the LaTeX preamble for use with this option.

	For example:

	.. code-block:: python

		latex_elements["preamble"] = r'''
			\makeatletter
			\newcolumntype{\Xx}[2]{>{\raggedright\arraybackslash}p{\dimexpr
				(\linewidth-\arrayrulewidth)*#1/#2-\tw@\tabcolsep-\arrayrulewidth\relax}}
			\makeatother
			'''

		autosummary_col_type = "\\Xx"


	.. versionadded:: 2.13.0
