---

• Temporarily patch Sphinx issue with singlehtml builder by inspecting the
  builder in template.

How the Table of Contents builds

Currently the left menu will build based upon any toctree(s) defined in your index.rst file.
It outputs 2 levels of depth, which should give your visitors a high level of access to your
docs. If no toctrees are set the theme reverts to sphinx's usual local toctree.

It's important to note that if you don't follow the same styling for your rST headers across
your documents, the toctree will misbuild, and the resulting menu might not show the correct
depth when it renders.

Also note that the table of contents is set with includehidden=true. This allows you
to set a hidden toc in your index file with the hidden_ property that will allow you
to build a toc without it rendering in your index.

By default, the navigation will "stick" to the screen as you scroll. However if your toc
is vertically too large, it will revert to static positioning. To disable the sticky nav
altogether change the setting in conf.py.

Contributing or modifying the theme

The sphinx_rtd_theme is primarily a sass_ project that requires a few other sass libraries. I'm
using bower_ to manage these dependencies and sass_ to build the css. The good news is
I have a very nice set of grunt_ operations that will not only load these dependencies, but watch
for changes, rebuild the sphinx demo docs and build a distributable version of the theme.
The bad news is this means you'll need to set up your environment similar to that
of a front-end developer (vs. that of a python developer). That means installing node and ruby.

Set up your environment

1. Install sphinx_ into a virtual environment.

.. code::

pip install sphinx

2. Install sass

.. code::

gem install sass

2. Install node, bower and grunt.

.. code::

// Install node
brew install node

// Install bower and grunt
npm install -g bower grunt-cli

// Now that everything is installed, let's install the theme dependecies.
npm install

Now that our environment is set up, make sure you're in your virtual environment, go to
this repository in your terminal and run grunt:

.. code::

grunt

This default task will do the following very cool things that make it worth the trouble.

1. It'll install and update any bower dependencies.
2. It'll run sphinx and build new docs.
3. It'll watch for changes to the sass files and build css from the changes.
4. It'll rebuild the sphinx docs anytime it notices a change to .rst, .html, .js
   or .css files.

Before you create an issue

I don't have a lot of time to maintain this project due to other responsibilities.
I know there are a lot of Python engineers out there that can't code sass / css and
are unable to submit pull requests. That said, submitting random style bugs without
at least providing sample documentation that replicates your problem is a good
way for me to ignore your request. RST unfortunately can spit out a lot of things
in a lot of ways. I don't have time to research your problem for you, but I do
have time to fix the actual styling issue if you can replicate the problem for me.

Releasing the Theme

When you release a new version,
you should do the following:

• Bump the version in sphinx_rtd_theme/__init__.py - we try to follow semver <http://semver.org/>_, so be careful with breaking changes.
• Run a grunt build to rebuild all the theme assets.
• Commit that change
• Tag the release in git: git tag $NEW_VERSION.
• Push the tag to GitHub: git push --tags origin
• Upload the package to PyPI: python setup.py sdist bdist_wheel upload
• In the readthedocs.org repo, edit the bower.json file to point at the correct version (sphinx-rtd-theme": "https://github.com/rtfd/sphinx-rtd-theme.git$NEW_VERSION")
• In the readthedocs.org repo, run gulp build to update the distributed theme files

TODO

• Separate some sass variables at the theme level so you can overwrite some basic colors.
