Summary
=======

``antidox`` is a Sphinx_ extension that can read Doxygen_ XML "databases" and
insert documentation for entities in Sphinx documents, similar to Breathe_.

It is intended to be *fast* and simple, though *easily customizable*.

Document generation (i.e. conversion between doxy-xml and reStructuredText) is
driven by XML stylesheets (powered by lxml_,) while indexing and selection of
documentable entities is done by a SQL database (sqlite3_.)

Here is an `example project <cbor_example_>`_ showing showing this extension in
action.

Example usage
=============

Generate the documentation for an entire header, and include all entities defined
in that header::

  .. doxy:c:: lua_run.h::*
      :children:
      
The syntax *<path>*::*<identifier>* can be used to disambiguate between entities
with the same name in different files.

To document a Doxygen group::

  .. doxy:c:: [CborPretty]
      :children:

You can manually specify which children should be documented::

  .. doxy:c:: be_uint16_t
      :children: u16

Cross references are provided by a custom role, e.g.::

  :doxy:r:`be_uint16_t::u16`

The complete syntax is decribed in the docs_.

Stub generation
---------------

The gen_stubs.py_ script shows how stub files can be automatically generated.
You can adapt this script to your own project.

Generating API docs this way is fast and convenient, but may be suboptimal,
since the spirit of this extension (and of Sphinx) is to generate narrative
documentation and not merely an API reference.

Note: Beta
==========

Though usable, this extension is still under development. Backwards
compatibility will be kept for all releases with the same major/minor version.

Be aware, however, that after updating this extension you may need to do a clean
build of your docs to see the results.

Objectives
==========

* Reuse API docs made with Doxygen in a Sphinx project.
* Provide a smooth transition between 100% automatic API docs (what Doxygen
  generates) and semi-manual documentation (autodoc-style).
* Have sensible defaults for automatic documentation generation while allowing
  customization.
* Deal with big projects efficiently: the main tool in use now (Breathe)
  has resource usage issues when dealing with large XML files.
