``sphinx.ext.autosummary`` -- Generate autodoc summaries
********************************************************

New in version 0.6.

This extension generates function/method/attribute summary lists,
similar to those output e.g. by Epydoc and other API doc generation
tools.  This is especially useful when your docstrings are long and
detailed, and putting each one of them on a separate page makes them
easier to read.

The ``sphinx.ext.autosummary`` extension does this in two parts:

1. There is an ``autosummary`` directive for generating summary
   listings that contain links to the documented items, and short
   summary blurbs extracted from their docstrings.

2. The convenience script **sphinx-autogen** or the new
   ``autosummary_generate`` config value can be used to generate short
   "stub" files for the entries listed in the ``autosummary``
   directives. These by default contain only the corresponding
   ``sphinx.ext.autodoc`` directive.

.. autosummary::

   Insert a table that contains links to documented items, and a short
   summary blurb (the first sentence of the docstring) for each of
   them.  The ``autosummary`` directive can also optionally serve as a
   ``toctree`` entry for the included items.

   For example,

      .. currentmodule:: sphinx

      .. autosummary::

         environment.BuildEnvironment
         util.relative_uri

   produces a table like this:

      +------------+--------------------------------------------------------------------------------------------+
      | ``environm | The environment in which the ReST files are translated.                                    |
      | ent.BuildE |                                                                                            |
      | nvironment |                                                                                            |
      | ``(srcdir, |                                                                                            |
      | ...)       |                                                                                            |
      +------------+--------------------------------------------------------------------------------------------+
      | ``util.rel | Return a relative URL from ``base`` to ``to``.                                             |
      | ative_uri` |                                                                                            |
      | `(base,    |                                                                                            |
      | to)        |                                                                                            |
      +------------+--------------------------------------------------------------------------------------------+

   Autosummary preprocesses the docstrings and signatures with the
   same ``autodoc-process-docstring`` and
   ``autodoc-process-signature`` hooks as ``autodoc``.

   **Options**

   * If you want the ``autosummary`` table to also serve as a
     ``toctree`` entry, use the ``toctree`` option, for example:

        .. autosummary::
           :toctree: DIRNAME

           sphinx.environment.BuildEnvironment
           sphinx.util.relative_uri

     The ``toctree`` option also signals to the **sphinx-autogen**
     script that stub pages should be generated for the entries listed
     in this directive.  The option accepts a directory name as an
     argument; **sphinx-autogen** will by default place its output in
     this directory. If no argument is given, output is placed in the
     same directory as the file that contains the directive.

   * If you don't want the ``autosummary`` to show function signatures
     in the listing, include the ``nosignatures`` option:

        .. autosummary::
           :nosignatures:

           sphinx.environment.BuildEnvironment
           sphinx.util.relative_uri

   * You can specify a custom template with the ``template`` option.
     For example,

        .. autosummary::
           :template: mytemplate.rst

           sphinx.environment.BuildEnvironment

     would use the template ``mytemplate.rst`` in your
     ``templates_path`` to generate the pages for all entries listed.
     See Customizing templates below.

     New in version 1.0.


**sphinx-autogen** -- generate autodoc stub pages
=================================================

The **sphinx-autogen** script can be used to conveniently generate
stub documentation pages for items included in ``autosummary``
listings.

For example, the command

   $ sphinx-autogen -o generated *.rst

will read all ``autosummary`` tables in the ``*.rst`` files that have
the ``:toctree:`` option set, and output corresponding stub pages in
directory ``generated`` for all documented items.  The generated pages
by default contain text of the form:

   sphinx.util.relative_uri
   ========================

   .. autofunction:: sphinx.util.relative_uri

If the ``-o`` option is not given, the script will place the output
files in the directories specified in the ``:toctree:`` options.


Generating stub pages automatically
===================================

If you do not want to create stub pages with **sphinx-autogen**, you
can also use this new config value:

autosummary_generate

   Boolean indicating whether to scan all found documents for
   autosummary directives, and to generate stub pages for each.

   Can also be a list of documents for which stub pages should be
   generated.

   The new files will be placed in the directories specified in the
   ``:toctree:`` options of the directives.


Customizing templates
=====================

New in version 1.0.

You can customize the stub page templates, in a similar way as the
HTML Jinja templates, see *Templating*. (``TemplateBridge`` is not
supported.)

Note: If you find yourself spending much time tailoring the stub
  templates, this may indicate that it's a better idea to write custom
  narrative documentation instead.

Autosummary uses the following template files:

* ``autosummary/base.rst`` -- fallback template

* ``autosummary/module.rst`` -- template for modules

* ``autosummary/class.rst`` -- template for classes

* ``autosummary/function.rst`` -- template for functions

* ``autosummary/attribute.rst`` -- template for class attributes

* ``autosummary/method.rst`` -- template for class methods

The following variables available in the templates:

name

   Name of the documented object, excluding the module and class
   parts.

objname

   Name of the documented object, excluding the module parts.

fullname

   Full name of the documented object, including module and class
   parts.

module

   Name of the module the documented object belongs to.

class

   Name of the class the documented object belongs to.  Only available
   for methods and attributes.

underline

   A string containing ``len(full_name) * '='``.

members

   List containing names of all members of the module or class.  Only
   available for modules and classes.

functions

   List containing names of "public" functions in the module.  Here,
   "public" here means that the name does not start with an
   underscore. Only available for modules.

classes

   List containing names of "public" classes in the module.  Only
   available for modules.

exceptions

   List containing names of "public" exceptions in the module.  Only
   available for modules.

methods

   List containing names of "public" methods in the class.  Only
   available for classes.

attributes

   List containing names of "public" attributes in the class.  Only
   available for classes.

Note: You can use the ``autosummary`` directive in the stub pages. Stub
  pages are generated also based on these directives.
