"""Register a new object type.
This method is a very convenient way to add a new :term:`object` type
that can be cross-referenced. It will do this:
- Create a new directive (called *directivename*) for documenting an
object. It will automatically add index entries if *indextemplate*
is nonempty; if given, it must contain exactly one instance of
``%s``. See the example below for how the template will be
interpreted. * Create a new role (called *rolename*) to
cross-reference to these object descriptions.
- If you provide *parse_node*, it must be a function that takes a
string and a docutils node, and it must populate the node with
children parsed from the string. It must then return the name of the
item to be used in cross-referencing and index entries. See the
:file:`conf.py` file in the source for this documentation for an
example.
- The *objname* (if not given, will default to *directivename*) names
the type of object. It is used when listing objects, e.g. in search
results.
For example, if you have this call in a custom Sphinx extension::
app.add_object_type('directive', 'dir', 'pair: %s; directive')
you can use this markup in your documents::
.. rst:directive:: function
Document a function.
<...>
See also the :rst:dir:`function` directive.
For the directive, an index entry will be generated as if you had prepended ::
.. index:: pair: function; directive
The reference node will be of class ``literal`` (so it will be rendered
in a proportional font, as appropriate for code) unless you give the
*ref_nodeclass* argument, which must be a docutils node class. Most
useful are ``docutils.nodes.emphasis`` or ``docutils.nodes.strong`` --
you can also use ``docutils.nodes.generated`` if you want no further
text decoration. If the text should be treated as literal (e.g. no
smart quote replacement), but not have typewriter styling, use
``sphinx.addnodes.literal_emphasis`` or
``sphinx.addnodes.literal_strong``.

for standard Sphinx roles (see :ref:`xref-syntax`).

"""Register a new object type.
This method is a very convenient way to add a new :term:`object` type
that can be cross-referenced. It will do this:
- Create a new directive (called *directivename*) for documenting an
object. It will automatically add index entries if *indextemplate*
is nonempty; if given, it must contain exactly one instance of
``%s``. See the example below for how the template will be
interpreted. * Create a new role (called *rolename*) to
cross-reference to these object descriptions.
- If you provide *parse_node*, it must be a function that takes a
string and a docutils node, and it must populate the node with
children parsed from the string. It must then return the name of the
item to be used in cross-referencing and index entries. See the
:file:`conf.py` file in the source for this documentation for an
example.
- The *objname* (if not given, will default to *directivename*) names
the type of object. It is used when listing objects, e.g. in search
results.
For example, if you have this call in a custom Sphinx extension::
app.add_object_type('directive', 'dir', 'pair: %s; directive')
you can use this markup in your documents::
.. rst:directive:: function
Document a function.
<...>
See also the :rst:dir:`function` directive.
For the directive, an index entry will be generated as if you had prepended ::
.. index:: pair: function; directive
The reference node will be of class ``literal`` (so it will be rendered
in a proportional font, as appropriate for code) unless you give the
*ref_nodeclass* argument, which must be a docutils node class. Most
useful are ``docutils.nodes.emphasis`` or ``docutils.nodes.strong`` --
you can also use ``docutils.nodes.generated`` if you want no further
text decoration. If the text should be treated as literal (e.g. no
smart quote replacement), but not have typewriter styling, use
``sphinx.addnodes.literal_emphasis`` or
``sphinx.addnodes.literal_strong``.
For the role content, you have the same syntactical possibilities as
for standard Sphinx roles (see :ref:`xref-syntax`).
