sphinx.ext.autosectionlabel – Allow reference sections using its title

New in version 1.4.

This extension allows you to refer sections its title. This affects to the reference role (ref).

For example:

A Plain Title
-------------

This is the text of the section.

It refers to the section title, see :ref:`A Plain Title`.

Internally, this extension generates the labels for each section. If same section names are used in whole of document, any one is used for a target by default. The autosectionlabel_prefix_document configuration variable can be used to make headings which appear multiple times but in different documents unique.

Configuration

autosectionlabel_prefix_document: True to prefix each section label with the name of the document it is in, followed by a colon. For example, index:Introduction for a section called Introduction that appears in document index.rst. Useful for avoiding ambiguity when the same section heading appears in different documents.

autosectionlabel_maxdepth: If set, autosectionlabel chooses the sections for labeling by its depth. For example, when set 1 to autosectionlabel_maxdepth, labels are generated only for top level sections, and deeper sections are not labeled. It defaults to None (disabled).
