About

This package serves two purposes: it provides a default Sphinx configuration and set of extensions specific to the Astropy project, and it acts as a meta-package by installing all required Sphinx extensions for the core Astropy package and other packages.

Sphinx configuration

The default Sphinx configuration can be imported by putting:

from sphinx_astropy.conf import *

at the top of your conf.py file. You can then override specific settings from this default configuration, such as adding extensions or intersphinx packages. To give a clearer error messages for users, you can instead write:

try:
    from sphinx_astropy.conf import *
except ImportError:
    print('ERROR: the documentation requires the sphinx-astropy package to be installed')
    sys.exit(1)

Dependencies/extensions

Installing sphinx-astropy will automatically install (if not already present):

• Sphinx
• astropy-sphinx-theme - the default 'bootstrap' theme use by Astropy and a number of affiliated packages. This goes with sphinx_astropy.conf.v1.
• sphinx-automodapi - an extension that makes it easy to automatically generate API documentation.
• sphinx-gallery - an extension to generate example galleries
• numpydoc - an extension to parse docstrings in NumpyDoc format
• pillow - a package to deal with images, used by some examples in the astropy core documentation.
• pytest-doctestplus - providing the 'doctestplus' extension to skip code snippets in narrative documentation.

pydata-sphinx-theme (confv2)

To use the new pydata-sphinx-theme with sphinx_astropy.conf.v2, you have to install the optional [confv2] dependencies:

pip install sphinx-astropy[confv2]

That would pull in the following as well:

• pydata-sphinx-theme - a clean, three-column, Bootstrap-based Sphinx theme by and for the PyData community.
• sphinx-copybutton - a small Sphinx extension to add a "copy" button to code blocks.

astropy-unified theme (confv3)

To use the new astropy-unified theme, which is a derivative of pydata-sphinx-theme and sunpy-sphinx-theme with sphinx_astropy.conf.v3, you have to install the optional [confv3] dependencies:

pip install sphinx-astropy[confv3]

This would pull in the following as well:

• astropy-sphinx-theme >=3.0
• All confv3 dependencies.
