Reduce your documentation build size by selectively removing toctrees from pages.

Project description

Remove toctrees from Sphinx pages


Improve your Sphinx build time by selectively removing TocTree objects from pages. This is useful if your documentation uses auto-generated API documentation, which generates a lot of stub pages.

This extension can be used to remove the sidebar links for just the pages you specify, speed up the build considerably.

Who is this for?

This package is for maintainers that use Sphinx and have really large API documentation (or for some other reason, have a ton of nested pages). If you use a Sphinx theme that contains the entire Table of Contents on every page (e.g., any theme that has "collapsable" sidebar sections), this will slow things down considerably. Use this theme to speed up your builds.


Install the extension via pip:

$ pip install sphinx-remove-toctrees

activate it by adding it to your Sphinx extensions in



In, there is a top-level configuration key called remove_from_toctrees that allows you to specify the pages to remove from your sidebar. Provide a list of glob-like paths relative to your documentation root. Each entry should match to pages that should be removed from the sidebar.

For example, the following configuration will remove all pages from the folder api/generated, and the specific page subfolder/page_two.rst:

remove_from_toctrees = ["api/generated/*", "subfolder/page_two.rst"]

This is particularly useful in combination with the autosummary directive, which tends to generate a ton of stub-pages that slows things down.

If you have the following autosummary directive in a page at myfolder/page1.rst:

.. autosummary: datetime.datetime
   :toctree: api_gen

This will generate stub-pages in a myfolder/api_gen/ folder. To remove each of these pages from your sidebar, you would configure this extension like so:

remove_from_toctrees = ["myfolder/api_gen/*"]

Try it with this documentation

This extension doesn't have a hosted documentation page, but there is one in the docs/ folder of this repository. You can use that folder to preview this extension in action.

How this works

Sphinx keeps track of toctree objects to represent the structure of your documentation. These exist in the Sphinx environment object, at env.tocs. There are two places in the build where this is relevant here:

  • Early in the build, Sphinx uses these tocs to ensure that files in your documentation are linked somewhere, and will raise warnings if it finds a file that is not in one of the tocs.
  • Later in the build, Sphinx uses these tocs to build the HTML toctree with links to pages in your documentation. If there are many elements in tocs, it will take a long time to resolve all of these links!

This extension runs after the first step, but before the second step. It removes all the toctree objects that you specify, so that no warnings are raised about missing files, but they are removed from the sidebar and don't slow down your build.
