"""
This directive will produce an "autosummary"-style table for public
attributes of a specified module. See the `sphinx.ext.autosummary`_ extension
for details on this process. The main difference from the `autosummary`_
directive is that `autosummary`_ requires manually inputting all attributes
that appear in the table, while this captures the entries automatically.

This directive requires a single argument that must be a module or
package.

It also accepts any options supported by the `autosummary`_ directive-
see `sphinx.ext.autosummary`_ for details. It also accepts some additional
options:

    * ``:classes-only:``
        If present, the autosummary table will only contain entries for
        classes. This cannot be used at the same time with
        ``:functions-only:`` or ``:variables-only:``.

    * ``:functions-only:``
        If present, the autosummary table will only contain entries for
        functions. This cannot be used at the same time with
        ``:classes-only:`` or ``:variables-only:``.

    * ``:variables-only:``
        If present, the autosummary table will only contain entries for
        variables (everything except functions and classes). This cannot
        be used at the same time with ``:classes-only:`` or
        ``:functions-only:``.

    * ``:skip: obj1, [obj2, obj3, ...]``
        If present, specifies that the listed objects should be skipped
        and not have their documentation generated, nor be included in
        the summary table.

    * ``:allowed-package-names: pkgormod1, [pkgormod2, pkgormod3, ...]``
        Specifies the packages that functions/classes documented here are
        allowed to be from, as comma-separated list of package names. If not
        given, only objects that are actually in a subpackage of the package
        currently being documented are included.

    * ``:inherited-members:`` or ``:no-inherited-members:``
        The global sphinx configuration option ``automodsumm_inherited_members``
        decides if members that a class inherits from a base class are included
        in the generated documentation. The flags ``:inherited-members:`` or
        ``:no-inherited-members:`` allows overrriding this global setting.

    * ``:sort:``
        If the module contains ``__all__``, sort the module's objects
        alphabetically (if ``__all__`` is not present, the objects are found
        using `dir`, which always gives a sorted list).


This extension also adds three sphinx configuration options:

* ``automodsumm_writereprocessed``
    Should be a bool, and if ``True``, will cause `automodsumm`_ to write files
    with any ``automodsumm`` sections replaced with the content Sphinx
    processes after ``automodsumm`` has run.  The output files are not
    actually used by sphinx, so this option is only for figuring out the
    cause of sphinx warnings or other debugging.  Defaults to ``False``.

* ``automodsumm_inherited_members``
    Should be a bool and if ``True``, will cause `automodsumm`_ to document
    class members that are inherited from a base class. This value can be
    overriden for any particular automodsumm directive by including the
    ``:inherited-members:`` or ``:no-inherited-members:`` options.  Defaults to
    ``False``.

* ``automodsumm_included_members``
    A list of strings containing the names of hidden class members that should be
    included in the documentation. This is most commonly used to add special class
    methods like ``__getitem__`` and ``__setitem__``. Defaults to
    ``['__init__', '__call__']``.

* ``automodsumm_properties_are_attributes``
    Should be a bool and if ``True`` properties are treated as attributes in the
    documentation meaning that no property specific documentation is generated.
    Defaults to ``True``.

automod-diagram directive
=========================

This directive will produce an inheritance diagram like that of the
`sphinx.ext.inheritance_diagram`_ extension.

This directive requires a single argument that must be a module or
package. It accepts no options.

.. note::
    Like 'inheritance-diagram', 'automod-diagram' requires
    `graphviz <http://www.graphviz.org/>`_ to generate the inheritance diagram.
