# -*- coding: utf-8 -*-
"""Sphinx documentation plugin used to document tasks.

Introduction
============

Usage
-----

Add the extension to your :file:`docs/conf.py` configuration module:

.. code-block:: python

    extensions = (...,
                  'celery.contrib.sphinx')

If you'd like to change the prefix for tasks in reference documentation
then you can change the ``celery_task_prefix`` configuration value:

.. code-block:: python

    celery_task_prefix = '(task)'  # < default

With the extension installed `autodoc` will automatically find
task decorated objects and generate the correct (as well as
add a ``(task)`` prefix), and you can also refer to the tasks
using `:task:proj.tasks.add` syntax.

Use ``.. autotask::`` to manually document a task.
