.. highlight:: rest
:mod:`sphinx.ext.ifconfig` -- Include content based on configuration
====================================================================
.. module:: sphinx.ext.ifconfig
:synopsis: Include documentation content based on configuration values.
This extension is quite simple, and features only one directive:
.. warning::
This directive is designed to control only content of document. It could
not control sections, labels and so on.
.. rst:directive:: ifconfig
Include content of the directive only if the Python expression given as an
argument is ``True``, evaluated in the namespace of the project's
configuration (that is, all registered variables from :file:`conf.py` are
available).
For example, one could write ::
.. ifconfig:: releaselevel in ('alpha', 'beta', 'rc')
This stuff is only included in the built docs for unstable versions.
To make a custom config value known to Sphinx, use
:func:`~sphinx.application.Sphinx.add_config_value` in the setup function in
:file:`conf.py`, e.g.::
def setup(app):
app.add_config_value('releaselevel', '', 'env')
The second argument is the default value, the third should always be
``'env'`` for such values (it selects if Sphinx re-reads the documents if the
value changes).
