stsci-rtd-theme

This is a Sphinx theme for packages maintained by the Space Telescope Sciences Institute (STScI).

This theme inherits from sphinx-rtd-theme; however, the CSS styling has been altered for easier reading on a variety of platforms and browsers.

Installation

You can apply this theme to your current documents by installing the latest release from PyPI:

pip install stsci-rtd-theme

If you need the most up-to-date version of the master branch, you can install directly from GitHub:

pip install https://github.com/spacetelescope/stsci_rtd_theme.git

If you wish to modify the source code, you should clone the repository locally and install editable (-e):

git clone https://github.com/spacetelescope/stsci_rtd_theme.git
cd stsci_rtd_theme
pip install -e .

Sphinx configuration

If you haven't already created your Sphinx documentation, you can start sphinx with sphinx-quickstart and follow the guided steps. When you are finished, add these lines to your docs/conf.py file:

# docs/conf.py

import stsci_rtd_theme

html_theme = 'stsci_rtd_theme'
html_theme_path = [stsci_rtd_theme.get_html_theme_path()]

ReadTheDocs configuration

Add the following lines to your docs/conf.py file:

# docs/conf.py

import sphinx
import os
from packaging.version import Version


def setup(app):
    app.add_css_file("stsci.css")


extensions = [
    ...
]

on_rtd = os.environ.get('READTHEDOCS', None) == 'True'
if on_rtd:
    extensions.append('sphinx.ext.mathjax')
elif Version(sphinx.__version__) < Version('1.4'):
    extensions.append('sphinx.ext.pngmath')
else:
    extensions.append('sphinx.ext.imgmath')

Finally, make sure to include stsci-rtd-theme to the docs extra, or alternatively add stsci-rtd-theme to a rtd-requirements.txt file. Then, in .readthedocs.yml, include the following (depending on which of the two methods are used to define the stsci-rtd-theme dependency):

# .readthedocs.yml
install:
  - method: pip
    path: .
    extra_requirements:
      - docs

# .readthedocs.yml
install:
  - requirements: .rtd-requirements.txt
  - method: pip
    path: .
