Configuration file v2 (.readthedocs.yaml) ========================================= Read the Docs supports configuring your documentation builds with a configuration file. This file is named ``.readthedocs.yaml`` and should be placed in the top level of your Git repository. The ``.readthedocs.yaml`` file can contain a number of settings that are not accessible through the Read the Docs website. Because the file is stored in Git, the configuration will apply to the exact version that is being built. **This allows you to store different configurations for different versions of your documentation.** Below is an example YAML file which shows the most common configuration options: .. tabs:: .. tab:: Sphinx .. literalinclude:: /config-file/examples/sphinx/.readthedocs.yaml :language: yaml :linenos: :caption: .readthedocs.yaml .. tab:: MkDocs .. literalinclude:: /config-file/examples/mkdocs/.readthedocs.yaml :language: yaml :linenos: :caption: .readthedocs.yaml .. seealso:: :doc:`/config-file/index` Practical steps to add a configuration file to your documentation project. Supported settings ------------------ Read the Docs validates every configuration file. Any configuration option that isn't supported will make the build fail. This is to avoid typos and provide feedback on invalid configurations. .. warning:: When using a v2 configuration file, the local settings from the web interface are ignored. .. contents:: :local: :depth: 3 version ~~~~~~~ :Required: ``true`` Example: .. code-block:: yaml version: 2 formats ~~~~~~~ Additional formats of the documentation to be built, apart from the default HTML. :Type: ``list`` :Options: ``htmlzip``, ``pdf``, ``epub``, ``all`` :Default: ``[]`` Example: .. code-block:: yaml version: 2 # Default formats: [] .. code-block:: yaml version: 2 # Build PDF & ePub formats: - epub - pdf .. note:: You can use the ``all`` keyword to indicate all formats. .. code-block:: yaml version: 2 # Build all formats formats: all .. warning:: At the moment, only Sphinx supports additional formats. ``pdf``, ``epub``, and ``htmlzip`` output is not yet supported when using MkDocs. With :doc:`builds from pull requests `, only HTML formats are generated. Other formats are resource intensive and will be built after merging. python ~~~~~~ Configuration of the Python environment to be used. .. code-block:: yaml version: 2 python: install: - requirements: docs/requirements.txt - method: pip path: . extra_requirements: - docs - method: pip path: another/package python.install `````````````` List of installation methods of packages and requirements. You can have several of the following methods. :Type: ``list`` :Default: ``[]`` Requirements file ''''''''''''''''' Install packages from a requirements file. The path to the requirements file, relative to the root of the project. :Key: ``requirements`` :Type: ``path`` :Required: ``false`` Example: .. code-block:: yaml version: 2 python: install: - requirements: docs/requirements.txt - requirements: requirements.txt .. warning:: If you are using a :ref:`Conda ` environment to manage the build, this setting will not have any effect. Instead add the extra requirements to the ``environment`` file of Conda. Packages '''''''' Install the project using ``pip install`` (recommended) or ``python setup.py install`` (deprecated). The path to the package, relative to the root of the project. :Key: ``path`` :Type: ``path`` :Required: ``false`` The installation method. :Key: ``method`` :Options: ``pip``, ``setuptools`` (deprecated) :Default: ``pip`` `Extra requirements`_ section to install in addition to the `package dependencies`_. .. _Extra Requirements: https://setuptools.readthedocs.io/en/latest/userguide/dependency_management.html#optional-dependencies .. _package dependencies: https://setuptools.readthedocs.io/en/latest/userguide/dependency_management.html#declaring-required-dependency .. warning:: You need to install your project with ``pip`` to use ``extra_requirements``. :Key: ``extra_requirements`` :Type: ``list`` :Default: ``[]`` Example: .. code-block:: yaml version: 2 python: install: - method: pip path: . extra_requirements: - docs With the previous settings, Read the Docs will execute the next commands: .. prompt:: bash $ pip install .[docs] conda ~~~~~ Configuration for Conda support. .. code-block:: yaml version: 2 build: os: "ubuntu-22.04" tools: python: "mambaforge-22.9" conda: environment: environment.yml conda.environment ````````````````` The path to the Conda `environment file `_, relative to the root of the project. :Type: ``path`` :Required: ``false`` .. note:: When using Conda, it's required to specify ``build.tools.python`` to tell Read the Docs to use whether Conda or Mamba to create the environment. build ~~~~~ Configuration for the documentation build process. This allows you to specify the base Read the Docs image used to build the documentation, and control the versions of several tools: Python, Node.js, Rust, and Go. .. code-block:: yaml version: 2 build: os: ubuntu-22.04 tools: python: "3.12" nodejs: "18" rust: "1.64" golang: "1.19" build.os ```````` The Docker image used for building the docs. Image names refer to the operating system Read the Docs uses to build them. .. note:: Arbitrary Docker images are not supported. :Type: ``string`` :Options: ``ubuntu-20.04``, ``ubuntu-22.04`` :Required: ``true`` build.tools ``````````` Version specifiers for each tool. It must contain at least one tool. :Type: ``dict`` :Options: ``python``, ``nodejs``, ``rust``, ``golang`` :Required: ``true`` build.tools.python `````````````````` Python version to use. You can use several interpreters and versions, from CPython, Miniconda, and Mamba. .. note:: If you use Miniconda3 or Mambaforge, you can select the Python version using the ``environment.yml`` file. See our :doc:`/guides/conda` guide for more information. :Type: ``string`` :Options: - ``2.7`` - ``3`` (last stable CPython version) - ``3.6`` - ``3.7`` - ``3.8`` - ``3.9`` - ``3.10`` - ``3.11`` - ``3.12`` - ``miniconda3-4.7`` - ``mambaforge-4.10`` - ``mambaforge-22.9`` build.tools.nodejs `````````````````` Node.js version to use. :Type: ``string`` :Options: - ``14`` - ``16`` - ``18`` - ``19`` - ``20`` build.tools.rust ```````````````` Rust version to use. :Type: ``string`` :Options: - ``1.55`` - ``1.61`` - ``1.64`` - ``1.70`` build.tools.golang `````````````````` Go version to use. :Type: ``string`` :Options: - ``1.17`` - ``1.18`` - ``1.19`` - ``1.20`` build.apt_packages `````````````````` List of `APT packages`_ to install. Our build servers run various Ubuntu LTS versions with the default set of package repositories installed. We don't currently support PPA's or other custom repositories. .. _APT packages: https://packages.ubuntu.com/ :Type: ``list`` :Default: ``[]`` .. code-block:: yaml version: 2 build: apt_packages: - libclang - cmake .. note:: When possible avoid installing Python packages using apt (``python3-numpy`` for example), :doc:`use pip or conda instead `. .. warning:: Currently, it's not possible to use this option when using :ref:`config-file/v2:build.commands`. build.jobs `````````` Commands to be run before or after a Read the Docs :term:`pre-defined build jobs`. This allows you to run custom commands at a particular moment in the build process. See :doc:`/build-customization` for more details. .. code-block:: yaml version: 2 build: os: ubuntu-22.04 tools: python: "3.12" jobs: pre_create_environment: - echo "Command run at 'pre_create_environment' step" post_build: - echo "Command run at 'post_build' step" - echo `date` .. note:: Each key under ``build.jobs`` must be a list of strings. ``build.os`` and ``build.tools`` are also required to use ``build.jobs``. :Type: ``dict`` :Allowed keys: ``post_checkout``, ``pre_system_dependencies``, ``post_system_dependencies``, ``pre_create_environment``, ``post_create_environment``, ``pre_install``, ``post_install``, ``pre_build``, ``post_build`` :Required: ``false`` :Default: ``{}`` build.commands `````````````` Specify a list of commands that Read the Docs will run on the build process. When ``build.commands`` is used, none of the :term:`pre-defined build jobs` will be executed. (see :doc:`/build-customization` for more details). This allows you to run custom commands and control the build process completely. The ``$READTHEDOCS_OUTPUT/html`` directory will be uploaded and hosted by Read the Docs. .. warning:: This feature is in a *beta phase* and could suffer incompatible changes or even removed completely in the near feature. We are currently testing `the new addons integrations we are building `_ on projects using ``build.commands`` configuration key. Use it under your own responsibility. .. code-block:: yaml version: 2 build: os: ubuntu-22.04 tools: python: "3.12" commands: - pip install pelican - pelican --settings docs/pelicanconf.py --output $READTHEDOCS_OUTPUT/html/ docs/ .. note:: ``build.os`` and ``build.tools`` are also required when using ``build.commands``. :Type: ``list`` :Required: ``false`` :Default: ``[]`` sphinx ~~~~~~ Configuration for Sphinx documentation (this is the default documentation type). .. code-block:: yaml version: 2 sphinx: builder: html configuration: conf.py fail_on_warning: true .. note:: If you want to pin Sphinx to a specific version, use a ``requirements.txt`` or ``environment.yml`` file (see :ref:`config-file/v2:requirements file` and :ref:`config-file/v2:conda.environment`). If you are using a metadata file to describe code dependencies like ``setup.py``, ``pyproject.toml``, or similar, you can use the ``extra_requirements`` option (see :ref:`config-file/v2:packages`). This also allows you to override :ref:`the default pinning done by Read the Docs if your project was created before October 2020 `. sphinx.builder `````````````` The builder type for the Sphinx documentation. :Type: ``string`` :Options: ``html``, ``dirhtml``, ``singlehtml`` :Default: ``html`` .. note:: The ``htmldir`` builder option was renamed to ``dirhtml`` to use the same name as sphinx. Configurations using the old name will continue working. sphinx.configuration ```````````````````` The path to the ``conf.py`` file, relative to the root of the project. :Type: ``path`` :Default: ``null`` If the value is ``null``, Read the Docs will try to find a ``conf.py`` file in your project. sphinx.fail_on_warning `````````````````````` Turn warnings into errors (:option:`-W ` and :option:`--keep-going ` options). This means the build fails if there is a warning and exits with exit status 1. :Type: ``bool`` :Default: ``false`` mkdocs ~~~~~~ Configuration for MkDocs documentation. .. code-block:: yaml version: 2 mkdocs: configuration: mkdocs.yml fail_on_warning: false .. note:: If you want to pin MkDocs to a specific version, use a ``requirements.txt`` or ``environment.yml`` file (see :ref:`config-file/v2:requirements file` and :ref:`config-file/v2:conda.environment`). If you are using a metadata file to describe code dependencies like ``setup.py``, ``pyproject.toml``, or similar, you can use the ``extra_requirements`` option (see :ref:`config-file/v2:packages`). This also allows you to override :ref:`the default pinning done by Read the Docs if your project was created before March 2021 `. mkdocs.configuration ```````````````````` The path to the ``mkdocs.yml`` file, relative to the root of the project. :Type: ``path`` :Default: ``null`` If the value is ``null``, Read the Docs will try to find a ``mkdocs.yml`` file in your project. mkdocs.fail_on_warning `````````````````````` `Turn warnings into errors `__. This means that the build stops at the first warning and exits with exit status 1. :Type: ``bool`` :Default: ``false`` submodules ~~~~~~~~~~ VCS submodules configuration. .. note:: Only Git is supported at the moment. .. warning:: You can't use ``include`` and ``exclude`` settings for submodules at the same time. .. code-block:: yaml version: 2 submodules: include: - one - two recursive: true submodules.include `````````````````` List of submodules to be included. :Type: ``list`` :Default: ``[]`` .. note:: You can use the ``all`` keyword to include all submodules. .. code-block:: yaml version: 2 submodules: include: all submodules.exclude `````````````````` List of submodules to be excluded. :Type: ``list`` :Default: ``[]`` .. note:: You can use the ``all`` keyword to exclude all submodules. This is the same as ``include: []``. .. code-block:: yaml version: 2 submodules: exclude: all submodules.recursive ```````````````````` Do a recursive clone of the submodules. :Type: ``bool`` :Default: ``false`` .. note:: This is ignored if there aren't submodules to clone. search ~~~~~~ Settings for more control over :doc:`/server-side-search/index`. .. code-block:: yaml version: 2 search: ranking: api/v1/*: -1 api/v2/*: 4 ignore: - 404.html search.ranking `````````````` Set a custom search rank over pages matching a pattern. :Type: ``map`` of patterns to ranks :Default: ``{}`` Patterns are matched against the final html pages produced by the build (you should try to match `index.html`, not `docs/index.rst`). Patterns can include some special characters: - ``*`` matches everything - ``?`` matches any single character - ``[seq]`` matches any character in ``seq`` The rank can be an integer number between -10 and 10 (inclusive). Pages with a rank closer to -10 will appear further down the list of results, and pages with a rank closer to 10 will appear higher in the list of results. Note that 0 means *normal rank*, not *no rank*. If you are looking to completely ignore a page, check :ref:`config-file/v2:search.ignore`. .. code-block:: yaml version: 2 search: ranking: # Match a single file tutorial.html: 2 # Match all files under the api/v1 directory api/v1/*: -5 # Match all files that end with tutorial.html '*/tutorial.html': 3 .. note:: The final rank will be the last pattern to match the page. .. tip:: Is better to decrease the rank of pages you want to deprecate, rather than increasing the rank of the other pages. search.ignore ````````````` List of paths to ignore and exclude from the search index. Paths matched will not be included in search results. :Type: ``list`` of patterns :Default: ``['search.html', 'search/index.html', '404.html', '404/index.html']`` Patterns are matched against the relative path of html files produced by the build (you should try to match `index.html`, not `docs/index.rst`). Patterns can include some special characters: - ``*`` matches everything - ``?`` matches any single character - ``[seq]`` matches any character in ``seq`` .. code-block:: yaml version: 2 search: ignore: # Ignore a single file in the root of the output directory - 404.html # Ignore all files under the search/ directory - search/* # Ignore all files named ref.html nested inside one or more sub-folders - '*/ref.html' .. code-block:: yaml version: 2 search: ignore: # Custom files to ignore - file.html - api/v1/* # Defaults - search.html - search/index.html - 404.html - 404/index.html' .. note:: Since Read the Docs fallbacks to the original search engine when no results are found, you may still see search results from ignored pages.
