============= Configuration

.. module:: conf :synopsis: Build configuration file.

.. role:: code-c(code) :language: C .. role:: code-cpp(code) :language: C++ .. role:: code-js(code) :language: JavaScript .. role:: code-py(code) :language: Python .. role:: code-rst(code) :language: reStructuredText .. role:: code-tex(code) :language: LaTeX

The :term:configuration directory must contain a file named :file:conf.py. This file (containing Python code) is called the "build configuration file" and contains (almost) all configuration needed to customise Sphinx input and output behaviour.

An optional file docutils.conf_ can be added to the configuration directory to adjust Docutils_ configuration if not otherwise overridden or set by Sphinx.

.. _docutils: https://docutils.sourceforge.io/ .. _docutils.conf: https://docutils.sourceforge.io/docs/user/config.html

Important points to note:

  • If not otherwise documented, values must be strings, and their default is the empty string.

  • The term "fully-qualified name" (FQN) refers to a string that names an importable Python object inside a module; for example, the fully-qualified name :code-py:"sphinx.builders.Builder" means the :code-py:Builder class in the :code-py:sphinx.builders module.

  • Document names use / as the path separator and do not contain the file name extension.

.. _glob-style patterns:

  • Where glob-style patterns are permitted, you can use the standard shell constructs (*, ?, [...], and [!...]) with the feature that none of these will match slashes (/). A double star ** can be used to match any sequence of characters including slashes.

.. tip::

The configuration file is executed as Python code at build time (using :func:importlib.import_module, with the current directory set to the :term:configuration directory), and therefore can execute arbitrarily complex code.

Sphinx then reads simple names from the file's namespace as its configuration. In general, configuration values should be simple strings, numbers, or lists or dictionaries of simple values.

The contents of the config namespace are pickled (so that Sphinx can find out when configuration changes), so it may not contain unpickleable values -- delete them from the namespace with del if appropriate. Modules are removed automatically, so deleting imported modules is not needed.

.. _conf-tags:

Project tags

There is a special object named tags available in the config file, which exposes the :ref:project tags <tags>. Tags are defined either via the :option:--tag <sphinx-build --tag> command-line option or :code-py:tags.add('tag'). Note that the builder's name and format tags are not available in :file:conf.py.

It can be used to query and change the defined tags as follows:

  • To query whether a tag is set, use :code-py:'tag' in tags.
  • To add a tag, use :code-py:tags.add('tag').
  • To remove a tag, use :code-py:tags.remove('tag').

Project information

.. confval:: project :type: :code-py:str :default: :code-py:'Project name not set'

The documented project's name. Example:

.. code-block:: python

  project = 'Thermidor'

.. confval:: author :type: :code-py:str :default: :code-py:'Author name not set'

The project's author(s). Example:

.. code-block:: python

  author = 'Joe Bloggs'

.. _config-copyright:

.. confval:: copyright project_copyright :type: :code-py:str | Sequence[str] :default: :code-py:''

A copyright statement. Permitted styles are as follows, where 'YYYY' represents a four-digit year.

  • :code-py:copyright = 'YYYY'
  • :code-py:copyright = 'YYYY, Author Name'
  • :code-py:copyright = 'YYYY Author Name'
  • :code-py:copyright = 'YYYY-YYYY, Author Name'
  • :code-py:copyright = 'YYYY-YYYY Author Name'

If the string :code-py:'%Y' appears in a copyright line, it will be replaced with the current four-digit year. For example:

  • :code-py:copyright = '%Y'
  • :code-py:copyright = '%Y, Author Name'
  • :code-py:copyright = 'YYYY-%Y, Author Name'

.. versionadded:: 3.5 The :code-py:project_copyright alias.

.. versionchanged:: 7.1 The value may now be a sequence of copyright statements in the above form, which will be displayed each to their own line.

.. versionchanged:: 8.1 Copyright statements support the :code-py:'%Y' placeholder.

.. confval:: version :type: :code-py:str :default: :code-py:''

The major project version, used as the replacement for the :code-rst:|version| :ref:default substitution <default-substitutions>.

This may be something like :code-py:version = '4.2'. The full project version is defined in :confval:release.

If your project does not draw a meaningful distinction between between a 'full' and 'major' version, set both :code-py:version and :code-py:release to the same value.

.. confval:: release :type: :code-py:str :default: :code-py:''

The full project version, used as the replacement for the :code-rst:|release| :ref:default substitution <default-substitutions>, and e.g. in the HTML templates.

This may be something like :code-py:release = '4.2.1b0'. The major (short) project version is defined in :confval:version.

If your project does not draw a meaningful distinction between between a 'full' and 'major' version, set both :code-py:version and :code-py:release to the same value.

General configuration

.. confval:: needs_sphinx :type: :code-py:str :default: :code-py:''

Set a minimum supported version of Sphinx required to build the project. The format should be a 'major.minor' version string like '1.1' Sphinx will compare it with its version and refuse to build the project if the running version of Sphinx is too old. By default, there is no minimum version.

.. versionadded:: 1.0

.. versionchanged:: 1.4 Allow a 'major.minor.micro' version string.

.. confval:: extensions :type: :code-py:list[str] :default: :code-py:[]

A list of strings that are module names of :doc:Sphinx extensions <extensions/index>. These can be extensions bundled with Sphinx (named sphinx.ext.*) or custom first-party or third-party extensions.

To use a third-party extension, you must ensure that it is installed and include it in the :code-py:extensions list, like so:

.. code-block:: python

  extensions = [
      ...
      'numpydoc',
  ]

There are two options for first-party extensions. The configuration file itself can be an extension; for that, you only need to provide a :func:setup function in it. Otherwise, you must ensure that your custom extension is importable, and located in a directory that is in the Python path.

Ensure that absolute paths are used when modifying :data:sys.path. If your custom extensions live in a directory that is relative to the :term:configuration directory, use :meth:pathlib.Path.resolve like so:

.. code-block:: python

  import sys
  from pathlib import Path

  sys.path.append(str(Path('sphinxext').resolve()))

  extensions = [
     ...
     'extname',
  ]

The directory structure illustrated above would look like this:

.. code-block:: none

  <project directory>/
  ├── conf.py
  └── sphinxext/
      └── extname.py

.. confval:: needs_extensions :type: :code-py:dict[str, str] :default: :code-py:{}

If set, this value must be a dictionary specifying version requirements for extensions in :confval:extensions. The version strings should be in the 'major.minor' form. Requirements do not have to be specified for all extensions, only for those you want to check. Example:

.. code-block:: python

  needs_extensions = {
      'sphinxcontrib.something': '1.5',
  }

This requires that the extension declares its version in the :code-py:setup() function. See :ref:dev-extensions for further details.

.. versionadded:: 1.3

.. confval:: manpages_url :type: :code-py:str :default: :code-py:''

A URL to cross-reference :rst:role:manpage roles. If this is defined to https://manpages.debian.org/{path}, the :literal::manpage:man(1)`` role will link to https://manpages.debian.org/man(1). The patterns available are:

page The manual page (man) section The manual section (1) path The original manual page and section specified (man(1))

This also supports manpages specified as man.1.

.. code-block:: python

  # To use manpages.debian.org:
  manpages_url = 'https://manpages.debian.org/{path}'
  # To use man7.org:
  manpages_url = 'https://man7.org/linux/man-pages/man{section}/{page}.{section}.html'
  # To use linux.die.net:
  manpages_url = 'https://linux.die.net/man/{section}/{page}'
  # To use helpmanual.io:
  manpages_url = 'https://helpmanual.io/man{section}/{page}'

.. versionadded:: 1.7

.. confval:: today today_fmt

These values determine how to format the current date, used as the replacement for the :code-rst:|today| :ref:default substitution <default-substitutions>.

  • If you set :confval:today to a non-empty value, it is used.
  • Otherwise, the current time is formatted using :func:time.strftime and the format given in :confval:today_fmt.

The default for :confval:today is :code-py:'', and the default for :confval:today_fmt is :code-py:'%b %d, %Y' (or, if translation is enabled with :confval:language, an equivalent format for the selected locale).

Options for figure numbering

.. confval:: numfig :type: :code-py:bool :default: :code-py:False

If :code-py:True, figures, tables and code-blocks are automatically numbered if they have a caption. The :rst:role:numref role is enabled. Obeyed so far only by HTML and LaTeX builders.

.. note::

  The LaTeX builder always assigns numbers whether this option is enabled
  or not.

.. versionadded:: 1.3

.. confval:: numfig_format :type: :code-py:dict[str, str] :default: :code-py:{}

A dictionary mapping :code-py:'figure', :code-py:'table', :code-py:'code-block' and :code-py:'section' to strings that are used for format of figure numbers. The marker %s will be replaced with the figure number.

The defaults are:

.. code-block:: python

  numfig_format = {
      'code-block': 'Listing %s',
      'figure': 'Fig. %s',
      'section': 'Section',
      'table': 'Table %s',
  }

.. versionadded:: 1.3

.. confval:: numfig_secnum_depth :type: :code-py:int :default: :code-py:1

  • If set to :code-py:0, figures, tables, and code-blocks are continuously numbered starting at 1.
  • If :code-py:1, the numbering will be x.1, x.2, ... with x representing the section number. (If there is no top-level section, the prefix will not be added ). This naturally applies only if section numbering has been activated via the :numbered: option of the :rst:dir:toctree directive.
  • If :code-py:2, the numbering will be x.y.1, x.y.2, ... with x representing the section number and y the sub-section number. If located directly under a section, there will be no y. prefix, and if there is no top-level section, the prefix will not be added.
  • Any other positive integer can be used, following the rules above.

.. versionadded:: 1.3

.. versionchanged:: 1.7 The LaTeX builder obeys this setting if :confval:numfig is set to :code-py:True.

Options for highlighting

.. confval:: highlight_language :type: :code-py:str :default: :code-py:'default'

The default language to highlight source code in. The default is :code-py:'default', which suppresses warnings if highlighting as Python code fails.

The value should be a valid Pygments lexer name, see :ref:code-examples for more details.

.. versionadded:: 0.5

.. versionchanged:: 1.4 The default is now :code-py:'default'.

.. confval:: highlight_options :type: :code-py:dict[str, dict[str, Any]] :default: :code-py:{}

A dictionary that maps Pygments lexer names to their options. These are lexer-specific; for the options understood by each, see the Pygments documentation <https://pygments.org/docs/lexers>_.

Example:

.. code-block:: python

 highlight_options = {
   'default': {'stripall': True},
   'php': {'startinline': True},
 }

.. versionadded:: 1.3 .. versionchanged:: 3.5

  Allow configuring highlight options for multiple lexers.

.. confval:: pygments_style :type: :code-py:str :default: :code-py:'sphinx'

The style name to use for Pygments highlighting of source code. If not set, either the theme's default style or :code-py:'sphinx' is selected for HTML output.

.. versionchanged:: 0.3 If the value is a fully-qualified name of a custom Pygments style class, this is then used as custom style.

Options for HTTP requests

.. confval:: tls_verify :type: :code-py:bool :default: :code-py:True

If True, Sphinx verifies server certificates.

.. versionadded:: 1.5

.. confval:: tls_cacerts :type: :code-py:str | dict[str, str] :default: :code-py:''

A path to a certification file of CA or a path to directory which contains the certificates. This also allows a dictionary mapping hostnames to the certificate file path. The certificates are used to verify server certifications.

.. versionadded:: 1.5

.. tip::

  Sphinx uses requests_ as a HTTP library internally.
  If :confval:`!tls_cacerts` is not set,
  Sphinx falls back to requests' default behaviour.
  See :ref:`requests:verification` for further details.

  .. _requests: https://requests.readthedocs.io/

.. confval:: user_agent :type: :code-py:str :default: :code-py:'Mozilla/5.0 (X11; Linux x86_64; rv:100.0) Gecko/20100101 \ Firefox/100.0 Sphinx/X.Y.Z'

Set the User-Agent used by Sphinx for HTTP requests.

.. versionadded:: 2.3

.. _intl-options:

Options for internationalisation

These options influence Sphinx's Native Language Support. See the documentation on :ref:intl for details.

.. confval:: language :type: :code-py:str :default: :code-py:'en'

The code for the language the documents are written in. Any text automatically generated by Sphinx will be in that language. Also, Sphinx will try to substitute individual paragraphs from your documents with the translation sets obtained from :confval:locale_dirs. Sphinx will search language-specific figures named by :confval:figure_language_filename (e.g. the German version of myfigure.png will be myfigure.de.png by default setting) and substitute them for original figures. In the LaTeX builder, a suitable language will be selected as an option for the Babel package.

.. versionadded:: 0.5

.. versionchanged:: 1.4 Support figure substitution

.. versionchanged:: 5.0 The default is now :code-py:'en' (previously :code-py:None).

.. confval:: locale_dirs :type: :code-py:list[str] :default: :code-py:['locales']

Directories in which to search for additional message catalogs (see :confval:language), relative to the source directory. The directories on this path are searched by the :mod:gettext module.

Internal messages are fetched from a text domain of sphinx; so if you add the directory :file:./locales to this setting, the message catalogs (compiled from .po format using :program:msgfmt) must be in :file:./locales/{language}/LC_MESSAGES/sphinx.mo. The text domain of individual documents depends on :confval:gettext_compact.

.. note:: The :option:-v option to sphinx-build <sphinx-build -v> is useful to check the :confval:!locale_dirs setting is working as expected. If the message catalog directory not found, debug messages are emitted.

.. versionadded:: 0.5

.. versionchanged:: 1.5 Use locales directory as a default value

.. confval:: gettext_allow_fuzzy_translations :type: :code-py:bool :default: :code-py:False

If True, "fuzzy" messages in the message catalogs are used for translation.

.. versionadded:: 4.3

.. confval:: gettext_compact :type: :code-py:bool | str :default: :code-py:True

  • If :code-py:True, a document's text domain is its docname if it is a top-level project file and its very base directory otherwise.
  • If :code-py:False, a document's text domain is the docname, in full.
  • If set to a string, every document's text domain is set to this string, making all documents use single text domain.

With :code-py:gettext_compact = True, the document :file:markup/code.rst ends up in the markup text domain. With this option set to :code-py:False, it is markup/code. With this option set to :code-py:'sample', it is sample.

.. versionadded:: 1.1

.. versionchanged:: 3.3 Allow string values.

.. confval:: gettext_uuid :type: :code-py:bool :default: :code-py:False

If :code-py:True, Sphinx generates UUID information for version tracking in message catalogs. It is used to:

  • Add a UUID line for each msgid in .pot files.
  • Calculate similarity between new msgids and previously saved old msgids. (This calculation can take a long time.)

.. tip:: If you want to accelerate the calculation, you can use a third-party package (Levenshtein_) by running :command:pip install levenshtein.

  .. _Levenshtein: https://pypi.org/project/Levenshtein/

.. versionadded:: 1.3

.. confval:: gettext_location :type: :code-py:bool :default: :code-py:True

If :code-py:True, Sphinx generates location information for messages in message catalogs.

.. versionadded:: 1.3

.. confval:: gettext_auto_build :type: :code-py:bool :default: :code-py:True

If :code-py:True, Sphinx builds a .mo file for each translation catalog file.

.. versionadded:: 1.3

.. confval:: gettext_additional_targets :type: :code-py:set[str] | Sequence[str] :default: :code-py:[]

Enable gettext translation for certain element types. Example:

.. code-block:: python

  gettext_additional_targets = {'literal-block', 'image'}

The following element types are supported:

  • :code-py:'index' -- index terms
  • :code-py:'literal-block' -- literal blocks (:: annotation and code-block directive)
  • :code-py:'doctest-block' -- doctest block
  • :code-py:'raw' -- raw content
  • :code-py:'image' -- image/figure uri

.. versionadded:: 1.3 .. versionchanged:: 4.0 The alt text for images is translated by default. .. versionchanged:: 7.4 Permit and prefer a set type.

.. confval:: figure_language_filename :type: :code-py:str :default: :code-py:'{root}.{language}{ext}'

The filename format for language-specific figures. The available format tokens are:

  • {root}: the filename, including any path component, without the file extension. For example: images/filename.
  • {path}: the directory path component of the filename, with a trailing slash if non-empty. For example: images/.
  • {basename}: the filename without the directory path or file extension components. For example: filename.
  • {ext}: the file extension. For example: .png.
  • {language}: the translation language. For example: en.
  • {docpath}: the directory path component for the current document, with a trailing slash if non-empty. For example: dirname/.

By default, an image directive :code-rst:.. image:: images/filename.png, using an image at :file:images/filename.png, will use the language-specific figure filename :file:images/filename.en.png.

If :confval:!figure_language_filename is set as below, the language-specific figure filename will be :file:images/en/filename.png instead.

.. code-block:: python

  figure_language_filename = '{path}{language}/{basename}{ext}'

.. versionadded:: 1.4

.. versionchanged:: 1.5 Added {path} and {basename} tokens.

.. versionchanged:: 3.2 Added {docpath} token.

.. confval:: translation_progress_classes :type: :code-py:bool | 'translated' | 'untranslated' :default: :code-py:False

Control which, if any, classes are added to indicate translation progress. This setting would likely only be used by translators of documentation, in order to quickly indicate translated and untranslated content.

:code-py:True Add translated and untranslated classes to all nodes with translatable content. :code-py:'translated' Only add the translated class. :code-py:'untranslated' Only add the untranslated class. :code-py:False Do not add any classes to indicate translation progress.

.. versionadded:: 7.1

Options for markup

.. confval:: default_role :type: :code-py:str :default: :code-py:None

.. index:: default; role

The name of a reStructuredText role (builtin or Sphinx extension) to use as the default role, that is, for text marked up like this. This can be set to :code-py:'py:obj' to make filter a cross-reference to the Python function "filter".

The default role can always be set within individual documents using the standard reStructuredText :dudir:default-role directive.

.. versionadded:: 0.4

.. confval:: keep_warnings :type: :code-py:bool :default: :code-py:False

Keep warnings as "system message" paragraphs in the rendered documents. Warnings are always written to the standard error stream when :program:sphinx-build is run, regardless of this setting.

.. versionadded:: 0.5

.. confval:: option_emphasise_placeholders :type: :code-py:bool :default: :code-py:False

When enabled, emphasise placeholders in :rst:dir:option directives. To display literal braces, escape with a backslash (\{). For example, option_emphasise_placeholders=True and .. option:: -foption={TYPE} would render with TYPE emphasised.

.. versionadded:: 5.1

.. confval:: primary_domain :type: :code-py:str :default: :code-py:'py'

.. index:: pair: default; domain

The name of the default :doc:domain </usage/domains/index>. Can also be :code-py:None to disable a default domain. The default is :code-py:'py', for the Python domain.

Those objects in other domain (whether the domain name is given explicitly, or selected by a :rst:dir:default-domain directive) will have the domain name explicitly prepended when named (e.g., when the default domain is C, Python functions will be named "Python function", not just "function"). Example:

.. code-block:: python

  primary_domain = 'cpp'

.. versionadded:: 1.0

.. confval:: rst_epilog :type: :code-py:str :default: :code-py:''

.. index:: pair: global; substitutions

A string of reStructuredText that will be included at the end of every source file that is read. This is a possible place to add substitutions that should be available in every file (another being :confval:rst_prolog). Example:

.. code-block:: python

  rst_epilog = """
  .. |psf| replace:: Python Software Foundation
  """

.. versionadded:: 0.6

.. confval:: rst_prolog :type: :code-py:str :default: :code-py:''

.. index:: pair: global; substitutions

A string of reStructuredText that will be included at the beginning of every source file that is read. This is a possible place to add substitutions that should be available in every file (another being :confval:rst_epilog). Example:

.. code-block:: python

  rst_prolog = """
  .. |psf| replace:: Python Software Foundation
  """

.. versionadded:: 1.0

.. confval:: show_authors :type: :code-py:bool :default: :code-py:False

A boolean that decides whether :rst:dir:codeauthor and :rst:dir:sectionauthor directives produce any output in the built files.

.. confval:: trim_footnote_reference_space :type: :code-py:bool :default: :code-py:False

Trim spaces before footnote references that are necessary for the reStructuredText parser to recognise the footnote, but do not look too nice in the output.

.. versionadded:: 0.6

.. _math-options:

Options for Maths

These options control maths markup and notation.

.. confval:: math_eqref_format :type: :code-py:str :default: :code-py:'({number})'

A string used for formatting the labels of references to equations. The {number} place-holder stands for the equation number.

Example: 'Eq.{number}' gets rendered as, for example, Eq.10.

.. versionadded:: 1.7

.. confval:: math_number_all :type: :code-py:bool :default: :code-py:False

Force all displayed equations to be numbered. Example:

.. code-block:: python

  math_number_all = True

.. versionadded:: 1.4

.. confval:: math_numfig :type: :code-py:bool :default: :code-py:True

If :code-py:True, displayed math equations are numbered across pages when :confval:numfig is enabled. The :confval:numfig_secnum_depth setting is respected. The :rst:role:eq, not :rst:role:numref, role must be used to reference equation numbers.

.. versionadded:: 1.7

.. confval:: math_numsep :type: :code-py:str :default: :code-py:'.'

A string that defines the separator between section numbers and the equation number when :confval:numfig is enabled and :confval:numfig_secnum_depth is positive.

Example: :code-py:'-' gets rendered as 1.2-3.

.. versionadded:: 7.4

Options for the nitpicky mode

.. confval:: nitpicky :type: :code-py:bool :default: :code-py:False

Enables nitpicky mode if :code-py:True. In nitpicky mode, Sphinx will warn about all references where the target cannot be found. This is recommended for new projects as it ensures that all references are to valid targets.

You can activate this mode temporarily using the :option:--nitpicky <sphinx-build --nitpicky> command-line option. See :confval:nitpick_ignore for a way to mark missing references as "known missing".

.. code-block:: python

  nitpicky = True

.. versionadded:: 1.0

.. confval:: nitpick_ignore :type: :code-py:set[tuple[str, str]] | Sequence[tuple[str, str]] :default: :code-py:()

A set or list of :code-py:(warning_type, target) tuples that should be ignored when generating warnings in :confval:"nitpicky mode" <nitpicky>. Note that warning_type should include the domain name if present. Example:

.. code-block:: python

  nitpick_ignore = {
      ('py:func', 'int'),
      ('envvar', 'LD_LIBRARY_PATH'),
  }

.. versionadded:: 1.1 .. versionchanged:: 6.2 Changed allowable container types to a set, list, or tuple

.. confval:: nitpick_ignore_regex :type: :code-py:set[tuple[str, str]] | Sequence[tuple[str, str]] :default: :code-py:()

An extended version of :confval:nitpick_ignore, which instead interprets the warning_type and target strings as regular expressions. Note that the regular expression must match the whole string (as if the ^ and $ markers were inserted).

For example, (r'py:.*', r'foo.*bar\.B.*') will ignore nitpicky warnings for all python entities that start with 'foo' and have 'bar.B' in them, such as :code-py:('py:const', 'foo_package.bar.BAZ_VALUE') or :code-py:('py:class', 'food.bar.Barman').

.. versionadded:: 4.1 .. versionchanged:: 6.2 Changed allowable container types to a set, list, or tuple

Options for object signatures

.. confval:: add_function_parentheses :type: :code-py:bool :default: :code-py:True

A boolean that decides whether parentheses are appended to function and method role text (e.g. the content of ``:func:`input```) to signify that the name is callable.

.. confval:: maximum_signature_line_length :type: :code-py:int | None :default: :code-py:None

If a signature's length in characters exceeds the number set, each parameter within the signature will be displayed on an individual logical line.

When :code-py:None, there is no maximum length and the entire signature will be displayed on a single logical line.

A 'logical line' is similar to a hard line break---builders or themes may choose to 'soft wrap' a single logical line, and this setting does not affect that behaviour.

Domains may provide options to suppress any hard wrapping on an individual object directive, such as seen in the C, C++, and Python domains (e.g. :rst:dir:py:function:single-line-parameter-list).

.. versionadded:: 7.1

.. confval:: strip_signature_backslash :type: :code-py:bool :default: :code-py:False

When backslash stripping is enabled then every occurrence of \\ in a domain directive will be changed to \, even within string literals. This was the behaviour before version 3.0, and setting this variable to :code-py:True will reinstate that behaviour.

.. versionadded:: 3.0

.. confval:: toc_object_entries :type: :code-py:bool :default: :code-py:True

Create table of contents entries for domain objects (e.g. functions, classes, attributes, etc.).

.. versionadded:: 5.2

.. confval:: toc_object_entries_show_parents :type: :code-py:'domain' | 'hide' | 'all' :default: :code-py:'domain'

A string that determines how domain objects (functions, classes, attributes, etc.) are displayed in their table of contents entry.

Use :code-py:'domain' to allow the domain to determine the appropriate number of parents to show. For example, the Python domain would show :code-py:Class.method() and :code-py:function(), leaving out the :code-py:module. level of parents.

Use :code-py:'hide' to only show the name of the element without any parents (i.e. :code-py:method()).

Use :code-py:'all' to show the fully-qualified name for the object (i.e. :code-py:module.Class.method()), displaying all parents.

.. versionadded:: 5.2

Options for source files

.. confval:: exclude_patterns :type: :code-py:Sequence[str] :default: :code-py:()

A list of glob-style patterns_ that should be excluded when looking for source files. They are matched against the source file names relative to the source directory, using slashes as directory separators on all platforms. :confval:exclude_patterns has priority over :confval:include_patterns.

Example patterns:

  • :code-py:'library/xml.rst' -- ignores the library/xml.rst file
  • :code-py:'library/xml' -- ignores the library/xml directory
  • :code-py:'library/xml*' -- ignores all files and directories starting with :code-py:library/xml
  • :code-py:'**/.git' -- ignores all .git directories
  • :code-py:'Thumbs.db' -- ignores all Thumbs.db files

:confval:exclude_patterns is also consulted when looking for static files in :confval:html_static_path and :confval:html_extra_path.

.. versionadded:: 1.0

.. confval:: include_patterns :type: :code-py:Sequence[str] :default: :code-py:('**',)

A list of glob-style patterns_ that are used to find source files. They are matched against the source file names relative to the source directory, using slashes as directory separators on all platforms. By default, all files are recursively included from the source directory. :confval:exclude_patterns has priority over :confval:include_patterns.

Example patterns:

  • :code-py:'**' -- all files in the source directory and subdirectories, recursively
  • :code-py:'library/xml' -- just the library/xml directory
  • :code-py:'library/xml*' -- all files and directories starting with library/xml
  • :code-py:'**/doc' -- all doc directories (this might be useful if documentation is co-located with source files)

.. versionadded:: 5.1

.. confval:: master_doc root_doc :type: :code-py:str :default: :code-py:'index'

Sphinx builds a tree of documents based on the :rst:dir:toctree directives contained within the source files. This sets the name of the document containing the master toctree directive, and hence the root of the entire tree. Example:

.. code-block:: python

  master_doc = 'contents'

.. versionchanged:: 2.0 Default is :code-py:'index' (previously :code-py:'contents').

.. versionadded:: 4.0 The :confval:!root_doc alias.

.. confval:: source_encoding :type: :code-py:str :default: :code-py:'utf-8-sig'

The file encoding of all source files. The recommended encoding is 'utf-8-sig'.

.. versionadded:: 0.5 .. deprecated:: 9.0 Support for source encodings other than UTF-8 is deprecated. Sphinx 11 will only support UTF-8 files.

.. confval:: source_suffix :type: :code-py:dict[str, str] | Sequence[str] | str :default: :code-py:{'.rst': 'restructuredtext'}

A dictionary mapping the file extensions (suffixes) of source files to their file types. Sphinx considers all files files with suffixes in :code-py:source_suffix to be source files. Example:

.. code-block:: python

  source_suffix = {
      '.rst': 'restructuredtext',
      '.txt': 'restructuredtext',
      '.md': 'markdown',
  }

By default, Sphinx only supports the :code-py:'restructuredtext' file type. Further file types can be added with extensions that register different source file parsers, such as MyST-Parser_. Refer to the extension's documentation to see which file types it supports.

.. _MyST-Parser: https://myst-parser.readthedocs.io/

If the value is a string or sequence of strings, Sphinx will consider that they are all :code-py:'restructuredtext' files.

.. note:: File extensions must begin with a dot ('.').

.. versionchanged:: 1.3 Support a list of file extensions.

.. versionchanged:: 1.8 Change to a map of file extensions to file types.

Options for smart quotes

.. confval:: smartquotes :type: :code-py:bool :default: :code-py:True

If :code-py:True, the Smart Quotes transform__ will be used to convert quotation marks and dashes to typographically correct entities.

__ https://docutils.sourceforge.io/docs/user/smartquotes.html

.. versionadded:: 1.6.6 Replaces the now-removed :confval:!html_use_smartypants. It applies by default to all builders except man and text (see :confval:smartquotes_excludes.)

.. note::

  A `docutils.conf`__ file located in the :term:`configuration directory`
  (or a global :file:`~/.docutils` file) is obeyed unconditionally if it
  *deactivates* smart quotes via the corresponding `Docutils option`__.
  But if it *activates* them, then :confval:`smartquotes` does prevail.

  __ https://docutils.sourceforge.io/docs/user/config.html
  __ https://docutils.sourceforge.io/docs/user/config.html#smart-quotes

.. confval:: smartquotes_action :type: :code-py:str :default: :code-py:'qDe'

Customise the Smart Quotes transform. See below for the permitted codes. The default :code-py:'qDe' educates normal q\ uote characters ", ', em- and en-D\ ashes ---, --, and e\ llipses .....

:code-py:'q' Convert quotation marks :code-py:'b' Convert backtick quotation marks (:literal:\`double'' only) :code-py:'B' Convert backtick quotation marks (:literal:``double'' and :literal:`single') :code-py:'d' Convert dashes (convert ``--`` to em-dashes and ``---`` to en-dashes) :code-py:'D' Convert dashes (old school) (convert ``--`` to en-dashes and ``---`` to em-dashes) :code-py:'i' Convert dashes (inverted old school) (convert ``--`` to em-dashes and ``---`` to en-dashes) :code-py:'e' Convert ellipses ``...`` :code-py:'w'` Convert '&quot;' entities to '"'

.. versionadded:: 1.6.6

.. confval:: smartquotes_excludes :type: :code-py:dict[str, list[str]] :default: :code-py:{'languages': ['ja'], 'builders': ['man', 'text']}

Control when the Smart Quotes transform is disabled. Permitted keys are :code-py:'builders' and :code-py:'languages', and The values are lists of strings.

Each entry gives a sufficient condition to ignore the :confval:smartquotes setting and deactivate the Smart Quotes transform. Example:

.. code-block:: python

 smartquotes_excludes = {
     'languages': ['ja'],
     'builders': ['man', 'text'],
 }

.. note::

  Currently, in case of invocation of :program:`make` with multiple
  targets, the first target name is the only one which is tested against
  the :code-py:`'builders'` entry and it decides for all.
  Also, a ``make text`` following ``make html`` needs to be issued
  in the form ``make text SPHINXOPTS="-E"`` to force re-parsing
  of source files, as the cached ones are already transformed.
  On the other hand the issue does not arise with
  direct usage of :program:`sphinx-build` as it caches
  (in its default usage) the parsed source files in per builder locations.

.. hint::

  An alternative way to effectively deactivate (or customise) the
  smart quotes for a given builder, for example ``latex``,
  is to use ``make`` this way:

  .. code-block:: console

     make latex SPHINXOPTS="-D smartquotes_action="

  This can follow some ``make html`` with no problem, in contrast to the
  situation from the prior note.

.. versionadded:: 1.6.6

Options for templating

.. confval:: template_bridge :type: :code-py:str :default: :code-py:''

A string with the fully-qualified name of a callable (or simply a class) that returns an instance of :class:~sphinx.application.TemplateBridge. This instance is then used to render HTML documents, and possibly the output of other builders (currently the changes builder). (Note that the template bridge must be made theme-aware if HTML themes are to be used.) Example:

.. code-block:: python

  template_bridge = 'module.CustomTemplateBridge'

.. confval:: templates_path :type: :code-py:Sequence[str] :default: :code-py:()

A list of paths that contain extra templates (or templates that overwrite builtin/theme-specific templates). Relative paths are taken as relative to the :term:configuration directory. Example:

.. code-block:: python

  templates_path = ['.templates']

.. versionchanged:: 1.3 As these files are not meant to be built, they are automatically excluded when discovering source files.

Options for warning control

.. confval:: show_warning_types :type: :code-py:bool :default: :code-py:True

Add the type of each warning as a suffix to the warning message. For example, WARNING: [...] [index] or WARNING: [...] [toc.circular]. This setting can be useful for determining which warnings types to include in a :confval:suppress_warnings list.

.. versionadded:: 7.3.0 .. versionchanged:: 8.0.0 The default is now :code-py:True.

.. confval:: suppress_warnings :type: :code-py:Sequence[str] :default: :code-py:()

A list of warning codes to suppress arbitrary warning messages.

.. versionadded:: 1.4

By default, Sphinx supports the following warning codes:

  • app.add_directive
  • app.add_generic_role
  • app.add_node
  • app.add_role
  • app.add_source_parser
  • config.cache
  • docutils
  • download.not_readable
  • duplicate_declaration.c
  • duplicate_declaration.cpp
  • epub.duplicated_toc_entry
  • epub.unknown_project_files

  • toc.duplicate_entry
  • toc.empty_glob
  • toc.excluded
  • toc.no_title
  • toc.not_included
  • toc.not_readable
  • toc.secnum

Extensions can also define their own warning types. Those defined by the first-party sphinx.ext extensions are:

  • autodoc
  • autodoc.import_object
  • autodoc.mocked_object
  • autosectionlabel.<document name>
  • autosummary
  • autosummary.import_cycle
  • duration
  • intersphinx.external

You can choose from these types. You can also give only the first component to exclude all warnings attached to it.

.. versionadded:: 1.4 ref.citation, ref.doc, ref.keyword, ref.numref, ref.option, ref.ref, and ref.term.

.. versionadded:: 1.4.2 app.add_directive, app.add_generic_role, app.add_node, app.add_role, and app.add_source_parser.

.. versionadded:: 9.0 duration.

Builder options

.. _html-options:

Options for HTML output

These options influence HTML output. Various other builders are derived from the HTML output, and also make use of these options.

.. confval:: html_theme :type: :code-py:str :default: :code-py:'alabaster'

The theme for HTML output. See the :doc:HTML theming section </usage/theming>.

.. versionadded:: 0.6 .. versionchanged:: 1.3 The default theme is now :code-py:'alabaster'.

.. confval:: html_theme_options :type: :code-py:dict[str, Any] :default: :code-py:{}

A dictionary of options that influence the look and feel of the selected theme. These are theme-specific. The options understood by the :ref:builtin themes <builtin-themes> are described :ref:here <builtin-themes>.

Stylesheets to use for HTML pages. The stylesheet given by the selected theme is used by default A file of that name must exist either in Sphinx's :file:static/ path or in one of the custom paths given in :confval:html_static_path. If you only want to add or override a few things from the theme, use CSS @import to import the theme's stylesheet.

.. versionchanged:: 5.1 The value can be a iterable of strings.

.. confval:: html_title :type: :code-py:str :default: :samp:'{project} {release} documentation'

The "title" for HTML documentation generated with Sphinx's own templates. This is appended to the <title> tag of individual pages, and used in the navigation bar as the "topmost" element.

.. confval:: html_short_title :type: :code-py:str :default: The value of html_title

A shorter "title" for HTML documentation. This is used for links in the header and in the HTML Help documentation.

.. versionadded:: 0.4

.. confval:: html_context :type: :code-py:dict[str, Any] :default: :code-py:{}

A dictionary of values to pass into the template engine's context for all pages. Single values can also be put in this dictionary using :program:sphinx-build's :option:--html-define <sphinx-build --html-define> command-line option.

.. versionadded:: 0.5

.. confval:: html_logo :type: :code-py:str :default: :code-py:''

If given, this must be the name of an image file (path relative to the :term:configuration directory) that is the logo of the documentation, or a URL that points an image file for the logo. It is placed at the top of the sidebar; its width should therefore not exceed 200 pixels.

.. versionadded:: 0.4.1 The image file will be copied to the _static directory, but only if the file does not already exist there. .. versionchanged:: 4.0 Also accepts a URL.

.. confval:: html_favicon :type: :code-py:str :default: :code-py:''

If given, this must be the name of an image file (path relative to the :term:configuration directory) that is the favicon_ of the documentation, or a URL that points an image file for the favicon. Browsers use this as the icon for tabs, windows and bookmarks. It should be a 16-by-16 pixel icon in the PNG, SVG, GIF, or ICO file formats.

.. _favicon: https://developer.mozilla.org/en-US/ docs/Web/HTML/Attributes/rel#icon

Example:

.. code-block:: python

  html_favicon = 'static/favicon.png'

.. versionadded:: 0.4 The image file will be copied to the _static, but only if the file does not already exist there.

.. versionchanged:: 4.0 Also accepts the URL for the favicon.

.. confval:: html_css_files :type: :code-py:Sequence[str | tuple[str, dict[str, str]]] :default: :code-py:[]

A list of CSS files. The entry must be a filename string or a tuple containing the filename string and the attributes dictionary. The filename must be relative to the :confval:html_static_path, or a full URI with scheme like :code-py:'https://example.org/style.css'. The attributes dictionary is used for the <link> tag's attributes.

Example:

.. code-block:: python

  html_css_files = [
      'custom.css',
      'https://example.com/css/custom.css',
      ('print.css', {'media': 'print'}),
  ]

The special attribute priority can be set as an integer to load the CSS file at an earlier or later step. For more information, refer to :meth:.Sphinx.add_css_file.

.. versionadded:: 1.8 .. versionchanged:: 3.5 Support the priority attribute

.. confval:: html_js_files :type: :code-py:Sequence[str | tuple[str, dict[str, str]]] :default: :code-py:[]

A list of JavaScript files. The entry must be a filename string or a tuple containing the filename string and the attributes dictionary. The filename must be relative to the :confval:html_static_path, or a full URI with scheme like :code-py:'https://example.org/script.js'. The attributes dictionary is used for the <script> tag's attributes.

Example:

.. code-block:: python

  html_js_files = [
      'script.js',
      'https://example.com/scripts/custom.js',
      ('custom.js', {'async': 'async'}),
  ]

As a special attribute, priority can be set as an integer to load the JavaScript file at an earlier or later step. For more information, refer to :meth:.Sphinx.add_js_file.

.. versionadded:: 1.8 .. versionchanged:: 3.5 Support the priority attribute

.. confval:: html_static_path :type: :code-py:list[str] :default: :code-py:[]

A list of paths that contain custom static files (such as style sheets or script files). Relative paths are taken as relative to the :term:configuration directory. They are copied to the output's :file:_static directory after the theme's static files, so a file named :file:default.css will overwrite the theme's :file:default.css.

As these files are not meant to be built, they are automatically excluded from source files.

.. note::

  For security reasons, dotfiles under :confval:`!html_static_path`
  will not be copied.
  If you would like to copy them intentionally,
  explicitly add each file to this setting:

  .. code-block:: python

     html_static_path = ['_static', '_static/.htaccess']

  An alternative approach is to use :confval:`html_extra_path`,
  which allows copying dotfiles under the directories.

.. seealso::

  :meth:`~sphinx.application.Sphinx.add_static_dir`, for use in extensions
  to copy static files to the output directory.

.. versionchanged:: 0.4 The paths in :confval:html_static_path can now contain subdirectories.

.. versionchanged:: 1.0 The entries in :confval:html_static_path can now be single files.

.. versionchanged:: 1.8 The files under :confval:html_static_path are excluded from source files.

.. confval:: html_extra_path :type: :code-py:list[str] :default: :code-py:[]

A list of paths that contain extra files not directly related to the documentation, such as :file:robots.txt or :file:.htaccess. Relative paths are taken as relative to the :term:configuration directory. They are copied to the output directory. They will overwrite any existing file of the same name.

As these files are not meant to be built, they are automatically excluded from source files.

.. versionadded:: 1.2

.. versionchanged:: 1.4 The dotfiles in the extra directory will be copied to the output directory. And it refers :confval:exclude_patterns on copying extra files and directories, and ignores if path matches to patterns.

.. confval:: html_last_updated_fmt :type: :code-py:str :default: :code-py:None

If set, a 'Last updated on:' timestamp is inserted into the page footer using the given :func:~time.strftime format. The empty string is equivalent to :code-py:'%b %d, %Y' (or a locale-dependent equivalent).

.. confval:: html_last_updated_use_utc :type: :code-py:bool :default: :code-py:False

Use GMT/UTC (+00:00) instead of the system's local time zone for the time supplied to :confval:html_last_updated_fmt. This is most useful when the format used includes the time.

.. confval:: html_permalinks :type: :code-py:bool :default: :code-py:True

Add link anchors for each heading and description environment.

.. versionadded:: 3.5

.. confval:: html_permalinks_icon :type: :code-py:str :default: :code-py:'¶' (the paragraph sign)

Text for link anchors for each heading and description environment. HTML entities and Unicode are allowed.

.. versionadded:: 3.5

.. confval:: html_sidebars :type: :code-py:dict[str, Sequence[str]] :default: :code-py:{}

A dictionary defining custom sidebar templates, mapping document names to template names.

The keys can contain glob-style patterns_, in which case all matching documents will get the specified sidebars. (A warning is emitted when a more than one glob-style pattern matches for any document.)

Each value must be a list of strings which specifies the complete list of sidebar templates to include. If all or some of the default sidebars are to be included, they must be put into this list as well.

The default sidebars (for documents that don't match any pattern) are defined by theme itself. The builtin themes use these templates by default: :code-py:'localtoc.html', :code-py:'relations.html', :code-py:'sourcelink.html', and :code-py:'searchbox.html'.

The bundled first-party sidebar templates that can be rendered are:

  • localtoc.html -- a fine-grained table of contents of the current document
  • globaltoc.html -- a coarse-grained table of contents for the whole documentation set, collapsed
  • relations.html -- two links to the previous and next documents
  • sourcelink.html -- a link to the source of the current document, if enabled in :confval:html_show_sourcelink
  • searchbox.html -- the "quick search" box

Example:

.. code-block:: python

  html_sidebars = {
     '**': ['globaltoc.html', 'sourcelink.html', 'searchbox.html'],
     'using/windows': ['windows-sidebar.html', 'searchbox.html'],
  }

This will render the custom template windows-sidebar.html and the quick search box within the sidebar of the given document, and render the default sidebars for all other pages (except that the local TOC is replaced by the global TOC).

Note that this value only has no effect if the chosen theme does not possess a sidebar, like the builtin scrolls and haiku themes.

.. versionadded:: 1.0 The ability to use globbing keys and to specify multiple sidebars.

.. deprecated:: 1.7 A single string value for :confval:!html_sidebars will be removed.

.. versionchanged:: 2.0 :confval:!html_sidebars must be a list of strings, and no longer accepts a single string value.

.. confval:: html_additional_pages :type: :code-py:dict[str, str] :default: :code-py:{}

Additional templates that should be rendered to HTML pages, must be a dictionary that maps document names to template names.

Example:

.. code-block:: python

  html_additional_pages = {
      'download': 'custom-download.html.jinja',
  }

This will render the template :file:custom-download.html.jinja as the page :file:download.html.

.. confval:: html_domain_indices :type: :code-py:bool | Sequence[str] :default: :code-py:True

If True, generate domain-specific indices in addition to the general index. For e.g. the Python domain, this is the global module index.

This value can be a Boolean or a list of index names that should be generated. To find out the index name for a specific index, look at the HTML file name. For example, the Python module index has the name 'py-modindex'.

Example:

.. code-block:: python

  html_domain_indices = {
      'py-modindex',
  }

.. versionadded:: 1.0 .. versionchanged:: 7.4 Permit and prefer a set type.

.. confval:: html_use_index :type: :code-py:bool :default: :code-py:True

Controls if an index is added to the HTML documents.

.. versionadded:: 0.4

.. confval:: html_split_index :type: :code-py:bool :default: :code-py:False

Generates two versions of the index: once as a single page with all the entries, and once as one page per starting letter.

.. versionadded:: 0.4

.. confval:: html_copy_source :type: :code-py:bool :default: :code-py:True

If True, the reStructuredText sources are included in the HTML build as :file:_sources/{docname}.

.. confval:: html_show_sourcelink :type: :code-py:bool :default: :code-py:True

If True (and :confval:html_copy_source is true as well), links to the reStructuredText sources will be added to the sidebar.

.. versionadded:: 0.6

.. confval:: html_sourcelink_suffix :type: :code-py:str :default: :code-py:'.txt'

The suffix to append to source links (see :confval:html_show_sourcelink), unless files they have this suffix already.

.. versionadded:: 1.5

.. confval:: html_use_opensearch :type: :code-py:str :default: :code-py:''

If nonempty, an OpenSearch <https://github.com/dewitt/opensearch>_ description file will be output, and all pages will contain a <link> tag referring to it. Since OpenSearch doesn't support relative URLs for its search page location, the value of this option must be the base URL from which these documents are served (without trailing slash), e.g. :code-py:'https://docs.python.org'.

.. versionadded:: 0.2

.. confval:: html_file_suffix :type: :code-py:str :default: :code-py:'.html'

The file name suffix (file extension) for generated HTML files.

.. versionadded:: 0.4

.. confval:: html_link_suffix :type: :code-py:str :default: The value of html_file_suffix

The suffix for generated links to HTML files. Intended to support more esoteric server setups.

.. versionadded:: 0.6

If True, "© Copyright ..." is shown in the HTML footer, with the value or values from :confval:copyright.

.. versionadded:: 1.0

.. confval:: html_show_search_summary :type: :code-py:bool :default: :code-py:True

Show a summary of the search result, i.e., the text around the keyword.

.. versionadded:: 4.5

.. confval:: html_show_sphinx :type: :code-py:bool :default: :code-py:True

Add "Created using Sphinx_" to the HTML footer.

.. _Sphinx: https://www.sphinx-doc.org/

.. versionadded:: 0.4

.. confval:: html_output_encoding :type: :code-py:str :default: :code-py:'utf-8'

Encoding of HTML output files. This encoding name must both be a valid Python encoding name and a valid HTML charset value.

.. versionadded:: 1.0

.. confval:: html_compact_lists :type: :code-py:bool :default: :code-py:True

If True, a list all whose items consist of a single paragraph and/or a sub-list all whose items etc... (recursive definition) will not use the <p> element for any of its items. This is standard docutils behaviour. Default: :code-py:True.

.. versionadded:: 1.0

.. confval:: html_secnumber_suffix :type: :code-py:str :default: :code-py:'. '

Suffix for section numbers in HTML output. Set to :code-py:' ' to suppress the final dot on section numbers.

.. versionadded:: 1.0

.. confval:: html_search_language :type: :code-py:str :default: The value of language

Language to be used for generating the HTML full-text search index. This defaults to the global language selected with :confval:language. English (:code-py:'en') is used as a fall-back option if there is no support for this language.

Support exists for the following languages:

  • da -- Danish
  • nl -- Dutch
  • en -- English
  • fi -- Finnish
  • fr -- French
  • de -- German
  • hu -- Hungarian
  • it -- Italian
  • ja -- Japanese
  • no -- Norwegian
  • pt -- Portuguese
  • ro -- Romanian
  • ru -- Russian
  • es -- Spanish
  • sv -- Swedish
  • tr -- Turkish
  • zh -- Chinese

.. tip:: Accelerating build speed

  Each language (except Japanese) provides its own stemming algorithm.
  Sphinx uses a Python implementation by default.
  If you want to accelerate building the index file,
  you can use a third-party package (PyStemmer_) by running
  :command:`pip install PyStemmer`.

  .. _PyStemmer: https://pypi.org/project/PyStemmer/

.. versionadded:: 1.1 Support English (en) and Japanese (ja).

.. versionchanged:: 1.3 Added additional languages.

.. confval:: html_search_options :type: :code-py:dict[str, str] :default: :code-py:{}

A dictionary with options for the search language support. The meaning of these options depends on the language selected. Currently, only Japanese and Chinese support options.

:Japanese: type -- the type of the splitter to use. The other options depend on the splitter used.

     :code-py:`'sphinx.search.ja.DefaultSplitter'`
        The TinySegmenter algorithm, used by default.
     :code-py:`'sphinx.search.ja.MecabSplitter'`:
        The MeCab binding
        To use this splitter, the 'mecab' python binding
        or dynamic link library
        ('libmecab.so' for Linux, 'libmecab.dll' for Windows) is required.
     :code-py:`'sphinx.search.ja.JanomeSplitter'`:
        The Janome binding.
        To use this splitter,
        `Janome <https://pypi.org/project/Janome/>`_ is required.


     .. deprecated:: 1.6
        ``'mecab'``, ``'janome'`` and ``'default'`` is deprecated.
        To keep compatibility,
        ``'mecab'``, ``'janome'`` and ``'default'`` are also acceptable.

  Options for :code-py:`'mecab'`:
     :dic_enc:
        _`dic_enc option` is the encoding for the MeCab algorithm.
     :dict:
        _`dict option` is the dictionary to use for the MeCab algorithm.
     :lib:
        _`lib option` is the library name for finding the MeCab library
        via ``ctypes`` if the Python binding is not installed.

     For example:

     .. code-block:: python

         html_search_options = {
             'type': 'mecab',
             'dic_enc': 'utf-8',
             'dict': '/path/to/mecab .dic',
             'lib': '/path/to/libmecab.so',
         }

  Options for :code-py:`'janome'`:
     :user_dic:
        _`user_dic option` is the user dictionary file path for Janome.
     :user_dic_enc:
        _`user_dic_enc option` is the encoding for
        the user dictionary file specified by ``user_dic`` option.
        Default is 'utf8'.

:Chinese: dict The jieba dictionary path for using a custom dictionary.

.. versionadded:: 1.1

.. versionchanged:: 1.4 Allow any custom splitter in the type setting for Japanese.

.. confval:: html_search_scorer :type: :code-py:str :default: :code-py:''

The name of a JavaScript file (relative to the :term:configuration directory) that implements a search results scorer. If empty, the default will be used.

The scorer must implement the following interface, and may optionally define the :code-js:score() function for more granular control.

.. code-block:: javascript

  const Scorer = {
      // Implement the following function to further tweak the score for each result
      score: result => {
        const [docName, title, anchor, descr, score, filename] = result

        // ... calculate a new score ...
        return score
      },

      // query matches the full name of an object
      objNameMatch: 11,
      // or matches in the last dotted part of the object name
      objPartialMatch: 6,
      // Additive scores depending on the priority of the object
      objPrio: {
        0: 15, // used to be importantResults
        1: 5, // used to be objectResults
        2: -5, // used to be unimportantResults
      },
      //  Used when the priority is not in the mapping.
      objPrioDefault: 0,

      // query found in title
      title: 15,
      partialTitle: 7,

      // query found in terms
      term: 5,
      partialTerm: 2,
  };

.. versionadded:: 1.2

.. confval:: html_scaled_image_link :type: :code-py:bool :default: :code-py:True

Link images that have been resized with a scale option (scale, width, or height) to their original full-resolution image. This will not overwrite any link given by the target option on the the :dudir:image directive, if present.

.. tip::

  To disable this feature on a per-image basis,
  add the ``no-scaled-link`` class to the image directive:

  .. code-block:: rst

     .. image:: sphinx.png
        :scale: 50%
        :class: no-scaled-link

.. versionadded:: 1.3

.. versionchanged:: 3.0 Images with the no-scaled-link class will not be linked.

.. confval:: html_math_renderer :type: :code-py:str :default: :code-py:'mathjax'

The maths renderer to use for HTML output. The bundled renders are mathjax and imgmath. You must also load the relevant extension in :confval:extensions.

.. versionadded:: 1.8

Options for Single HTML output

These options influence Single HTML output. This builder derives from the HTML builder, so the HTML options also apply where appropriate.

.. confval:: singlehtml_sidebars :type: :code-py:dict[str, Sequence[str]] :default: The value of html_sidebars

A dictionary defining custom sidebar templates, mapping document names to template names.

This has the same effect as :confval:html_sidebars, but the only permitted key is :code-py:'index', and all other keys are ignored.

.. _htmlhelp-options:

This is the file name suffix for generated HTML help files.

.. versionadded:: 2.0

.. confval:: htmlhelp_link_suffix :type: :code-py:str :default: The value of htmlhelp_file_suffix

Suffix for generated links to HTML files.

.. versionadded:: 2.0

.. _applehelp-options:

Options for Apple Help output

.. versionadded:: 1.3

These options influence Apple Help output. This builder derives from the HTML builder, so the HTML options also apply where appropriate.

.. note::

Apple Help output will only work on Mac OS X 10.6 and higher, as it requires the :program:hiutil and :program:codesign command-line tools, neither of which are Open Source.

You can disable the use of these tools using :confval:applehelp_disable_external_tools, but the result will not be a valid help book until the indexer is run over the .lproj directories within the bundle.

.. TODO: Is this warning still relevant as of 2024-07? Needs updating by someone with a Mac.

.. confval:: applehelp_bundle_name :type: :code-py:str :default: The value of project

.. confval:: applehelp_icon :type: :code-py:str :default: :code-py:None

Path to the help bundle icon file or :code-py:None for no icon. According to Apple's documentation, this should be a 16-by-16 pixel version of the application's icon with a transparent background, saved as a PNG file.

.. confval:: applehelp_kb_product :type: :code-py:str :default: :samp:'{project}-{release}'

The product tag for use with :confval:applehelp_kb_url.

.. confval:: applehelp_kb_url :type: :code-py:str :default: :code-py:None

The URL for your knowledgebase server, e.g. https://example.com/kbsearch.py?p='product'&q='query'&l='lang'. At runtime, Help Viewer will replace 'product' with the contents of :confval:applehelp_kb_product, 'query' with the text entered by the user in the search box, and 'lang' with the user's system language.

Set this to to :code-py:None to disable remote search.

.. confval:: applehelp_remote_url :type: :code-py:str :default: :code-py:None

The URL for remote content. You can place a copy of your Help Book's Resources directory at this location and Help Viewer will attempt to use it to fetch updated content.

For example, if you set it to https://example.com/help/Foo/ and Help Viewer wants a copy of index.html for an English speaking customer, it will look at https://example.com/help/Foo/en.lproj/index.html.

Set this to to :code-py:None for no remote content.

.. confval:: applehelp_index_anchors :type: :code-py:bool :default: :code-py:False

Tell the help indexer to index anchors in the generated HTML. This can be useful for jumping to a particular topic using the AHLookupAnchor function or the openHelpAnchor:inBook: method in your code. It also allows you to use help:anchor URLs; see the Apple documentation for more information on this topic.

.. confval:: applehelp_min_term_length :type: :code-py:str :default: :code-py:None

Controls the minimum term length for the help indexer. If :code-py:None, use the default length.

.. confval:: applehelp_stopwords :type: :code-py:str :default: The value of language

Either a language specification (to use the built-in stopwords), or the path to a stopwords plist, or :code-py:None if you do not want to use stopwords.

Do not run the indexer or the code signing tool, no matter what other settings are specified.

This is mainly useful for testing, or where you want to run the Sphinx build on a non-macOS platform and then complete the final steps on a Mac for some reason.

.. _epub-options:

Options for EPUB output

These options influence EPUB output. This builder derives from the HTML builder, so the HTML options also apply where appropriate.

.. note:: The actual value for some of these options is not important, but they are required for the Dublin Core metadata_.

.. _Dublin Core metadata: https://dublincore.org/

.. confval:: epub_basename :type: :code-py:str :default: The value of project

The basename for the EPUB file.

.. confval:: epub_theme :type: :code-py:str :default: :code-py:'epub'

The HTML theme for the EPUB output. Since the default themes are not optimised for small screen space, using the same theme for HTML and EPUB output is usually not wise. This defaults to :code-py:'epub', a theme designed to save visual space.

.. confval:: epub_theme_options :type: :code-py:dict[str, Any] :default: :code-py:{}

A dictionary of options that influence the look and feel of the selected theme. These are theme-specific. The options understood by the :ref:builtin themes <builtin-themes> are described :ref:here <builtin-themes>.

.. confval:: epub_scheme :type: :code-py:str :default: :code-py:'unknown'

The publication scheme for the :confval:epub_identifier. This is put in the Dublin Core metadata. For published books the scheme is 'ISBN'. If you use the project homepage, 'URL' seems reasonable.

.. confval:: epub_uid :type: :code-py:str :default: :code-py:'unknown'

A unique identifier for the document. This is put in the Dublin Core metadata. You may use a XML's Name format_ string. You can't use hyphen, period, numbers as a first character.

.. confval:: epub_cover :type: :code-py:tuple[str, str] :default: :code-py:()

The cover page information. This is a tuple containing the filenames of the cover image and the html template. The rendered html cover page is inserted as the first item in the spine in :file:content.opf. If the template filename is empty, no html cover page is created. No cover at all is created if the tuple is empty.

Examples:

.. code-block:: python

  epub_cover = ('_static/cover.png', 'epub-cover.html')

A list of CSS files. The entry must be a filename string or a tuple containing the filename string and the attributes dictionary. The filename must be relative to the :confval:html_static_path, or a full URI with scheme like :code-py:'https://example.org/style.css'. The attributes dictionary is used for the <link> tag's attributes. For more information, see :confval:html_css_files.

.. versionadded:: 1.8

.. confval:: epub_guide :type: :code-py:Sequence[tuple[str, str, str]] :default: :code-py:()

Meta data for the guide element of :file:content.opf. This is a sequence of tuples containing the type, the uri and the title of the optional guide information. See the OPF documentation <https://idpf.org/epub>_ for details. If possible, default entries for the cover and toc types are automatically inserted. However, the types can be explicitly overwritten if the default entries are not appropriate.

Example:

.. code-block:: python

  epub_guide = (
      ('cover', 'cover.html', 'Cover Page'),
  )

The default value is :code-py:().

.. confval:: epub_pre_files :type: :code-py:Sequence[tuple[str, str]] :default: :code-py:()

Additional files that should be inserted before the text generated by Sphinx. It is a list of tuples containing the file name and the title. If the title is empty, no entry is added to :file:toc.ncx.

  epub_pre_files = [
      ('index.html', 'Welcome'),
  ]

.. confval:: epub_post_files :type: :code-py:Sequence[tuple[str, str]] :default: :code-py:()

Additional files that should be inserted after the text generated by Sphinx. It is a list of tuples containing the file name and the title. This option can be used to add an appendix. If the title is empty, no entry is added to :file:toc.ncx.

Example:

.. code-block:: python

  epub_post_files = [
      ('appendix.xhtml', 'Appendix'),
  ]

.. confval:: epub_exclude_files :type: :code-py:Sequence[str] :default: :code-py:[]

.. confval:: epub_tocdepth :type: :code-py:int :default: :code-py:3

The depth of the table of contents in the file :file:toc.ncx. It should be an integer greater than zero.

.. tip:: A deeply nested table of contents may be difficult to navigate.

.. confval:: epub_tocdup :type: :code-py:bool :default: :code-py:True

This flag determines if a ToC entry is inserted again at the beginning of its nested ToC listing. This allows easier navigation to the top of a chapter, but can be confusing because it mixes entries of different depth in one list.

.. confval:: epub_tocscope :type: :code-py:'default' | 'includehidden' :default: :code-py:'default'

This setting control the scope of the EPUB table of contents. The setting can have the following values:

:code-py:'default' Include all ToC entries that are not hidden :code-py:'includehidden' Include all ToC entries

.. versionadded:: 1.2

.. confval:: epub_fix_images :type: :code-py:bool :default: :code-py:False

Try and fix image formats that are not supported by some EPUB readers. At the moment palette images with a small colour table are upgraded. This is disabled by default because the automatic conversion may lose information. You need the Python Image Library (Pillow_) installed to use this option.

.. _Pillow: https://pypi.org/project/Pillow/

.. versionadded:: 1.2

.. confval:: epub_max_image_width :type: :code-py:int :default: :code-py:0

This option specifies the maximum width of images. If it is set to a valuevgreater than zero, images with a width larger than the given value are scaled accordingly. If it is zero, no scaling is performed. You need the Python Image Library (Pillow_) installed to use this option.

.. _latex-options:

Options for LaTeX output

These options influence LaTeX output.

.. confval:: latex_engine :type: :code-py:'pdflatex' | 'xelatex' | 'lualatex' | 'platex' | 'uplatex' :default: :code-py:'pdflatex'

The LaTeX engine to build the documentation. The setting can have the following values:

  • :code-py:'pdflatex' -- PDFLaTeX (default)
  • :code-py:'xelatex' -- XeLaTeX (default if :confval:language is one of el, zh_CN, or zh_TW)
  • :code-py:'lualatex' -- LuaLaTeX
  • :code-py:'platex' -- pLaTeX
  • :code-py:'uplatex' -- upLaTeX (default if :confval:language is :code-py:'ja')

.. important::

  ``'pdflatex'``\ 's support for Unicode characters is limited.
  If your project uses Unicode characters,
  setting the engine to ``'xelatex'`` or ``'lualatex'``
  and making sure to use an OpenType font with wide-enough glyph coverage
  is often easier than trying to make ``'pdflatex'`` work
  with the extra Unicode characters.
  Since Sphinx 2.0, the default typeface is GNU FreeFont,
  which has good coverage of Latin, Cyrillic, and Greek glyphs.

.. note::

  Sphinx 2.0 adds support for occasional Cyrillic and Greek letters or
  words in documents using a Latin language and ``'pdflatex'``.  To enable
  this, the :ref:`fontenc` key of :ref:`latex_elements
  <latex_elements_confval>` must be used appropriately.

.. note::

  Contrarily to :ref:`MathJaX math rendering in HTML output <math-support>`,
  LaTeX requires some extra configuration to support Unicode literals in
  :rst:dir:`math`:
  the only comprehensive solution (as far as we know) is to
  use ``'xelatex'`` or ``'lualatex'`` *and* to add
  ``r'\usepackage{unicode-math}'``
  (e.g. via the :ref:`preamble` key of :ref:`latex_elements
  <latex_elements_confval>`).
  You may prefer ``r'\usepackage[math-style=literal]{unicode-math}'``
  to keep a Unicode literal such as ``α`` (U+03B1) as-is in output,
  rather than being rendered as :math:`\alpha`.

.. versionchanged:: 2.1.0 Use 'xelatex' (and LaTeX package xeCJK) by default for Chinese documents.

.. versionchanged:: 2.2.1 Use 'xelatex' by default for Greek documents.

.. versionchanged:: 2.3 Add 'uplatex' support.

.. versionchanged:: 4.0 Use 'uplatex' by default for Japanese documents.

.. confval:: latex_documents :type: :code-py:Sequence[tuple[str, str, str, str, str, bool]] :default: The default LaTeX documents

This value determines how to group the document tree into LaTeX source files. It must be a list of tuples (startdocname, targetname, title, author, theme, toctree_only), where the items are:

startdocname String that specifies the :term:document name of the LaTeX file's master document. All documents referenced by the startdoc document in ToC trees will be included in the LaTeX file. (If you want to use the default master document for your LaTeX build, provide your :confval:master_doc here.)

targetname File name of the LaTeX file in the output directory.

title LaTeX document title. Can be empty to use the title of the startdoc document. This is inserted as LaTeX markup, so special characters like a backslash or ampersand must be represented by the proper LaTeX commands if they are to be inserted literally.

author Author for the LaTeX document. The same LaTeX markup caveat as for title applies. Use \\and to separate multiple authors, as in: 'John \\and Sarah' (backslashes must be Python-escaped to reach LaTeX).

theme LaTeX theme. See :confval:latex_theme.

toctree_only Must be :code-py:True or :code-py:False. If True, the startdoc document itself is not included in the output, only the documents referenced by it via ToC trees. With this option, you can put extra stuff in the master document that shows up in the HTML, but not the LaTeX output.

.. versionadded:: 0.3 The 6th item toctree_only. Tuples with 5 items are still accepted.

.. versionadded:: 1.2 In the past including your own document class required you to prepend the document class name with the string "sphinx". This is not necessary anymore.

.. confval:: latex_logo :type: :code-py:str :default: :code-py:''

If given, this must be the name of an image file (path relative to the :term:configuration directory) that is the logo of the documentation. It is placed at the top of the title page.

.. confval:: latex_toplevel_sectioning :type: :code-py:'part' | 'chapter' | 'section' :default: :code-py:None

This value determines the topmost sectioning unit. The default setting is 'section' if :confval:latex_theme is 'howto', and 'chapter' if it is 'manual'. The alternative in both cases is to specify 'part', which means that LaTeX document will use the :code-tex:\\part command.

In that case the numbering of sectioning units one level deep gets off-sync with HTML numbering, as by default LaTeX does not reset :code-tex:\\chapter numbering (or :code-tex:\\section for 'howto' theme) when encountering :code-tex:\\part command.

.. versionadded:: 1.4

.. confval:: latex_appendices :type: :code-py:Sequence[str] :default: :code-py:()

A list of document names to append as an appendix to all manuals. This is ignored if :confval:latex_theme is set to :code-py:'howto'.

.. confval:: latex_domain_indices :type: :code-py:bool | Sequence[str] :default: :code-py:True

If True, generate domain-specific indices in addition to the general index. For e.g. the Python domain, this is the global module index.

This value can be a Boolean or a list of index names that should be generated. To find out the index name for a specific index, look at the HTML file name. For example, the Python module index has the name 'py-modindex'.

Example:

.. code-block:: python

  latex_domain_indices = {
      'py-modindex',
  }

.. versionadded:: 1.0 .. versionchanged:: 7.4 Permit and prefer a set type.

.. confval:: latex_show_pagerefs :type: :code-py:bool :default: :code-py:False

Add page references after internal references. This is very useful for printed copies of the manual.

.. versionadded:: 1.0

.. confval:: latex_show_urls :type: :code-py:'no' | 'footnote' | 'inline' :default: :code-py:'no'

Control how to display URL addresses. This is very useful for printed copies of the manual. The setting can have the following values:

:code-py:'no' Do not display URLs :code-py:'footnote' Display URLs in footnotes :code-py:'inline' Display URLs inline in parentheses

.. versionadded:: 1.0 .. versionchanged:: 1.1 This value is now a string; previously it was a boolean value, and a true value selected the :code-py:'inline' display. For backwards compatibility, :code-py:True is still accepted.

.. confval:: latex_use_latex_multicolumn :type: :code-py:bool :default: :code-py:False

Use standard LaTeX's :code-tex:\\multicolumn for merged cells in tables.

:code-py:False Sphinx's own macros are used for merged cells from grid tables. They allow general contents (literal blocks, lists, blockquotes, ...) but may have problems if the :rst:dir:tabularcolumns directive was used to inject LaTeX mark-up of the type >{..}, <{..}, @{..} as column specification. :code-py:True Use LaTeX's standard :code-tex:\\multicolumn; this is incompatible with literal blocks in horizontally merged cells, and also with multiple paragraphs in such cells if the table is rendered using tabulary.

.. versionadded:: 1.6

.. confval:: latex_table_style :type: :code-py:list[str] :default: :code-py:['booktabs', 'colorrows']

A list of styling classes (strings). Currently supported:

:code-py:'booktabs' No vertical lines, and only 2 or 3 horizontal lines (the latter if there is a header), using the booktabs_ package.

:code-py:'borderless' No lines whatsoever.

:code-py:'colorrows' The table rows are rendered with alternating background colours. The interface to customise them is via :ref:dedicated keys <tablecolors> of :ref:latexsphinxsetup.

  .. important::

     With the :code-py:`'colorrows'` style,
     the :code-tex:`\\rowcolors` LaTeX command becomes a no-op
     (this command has limitations and has never correctly
     supported all types of tables Sphinx produces in LaTeX).
     Please use the
     :ref:`latex table color configuration <tablecolors>` keys instead.

To customise the styles for a table, use the :class: option if the table is defined using a directive, or otherwise insert a :ref:rst-class <rstclass> directive before the table (cf. :ref:table-directives).

Currently recognised classes are booktabs, borderless, standard, colorrows, nocolorrows. The latter two can be combined with any of the first three. The standard class produces tables with both horizontal and vertical lines (as had been the default prior to Sphinx 6.0.0).

A single-row multi-column merged cell will obey the row colour, if it is set. See also TableMergeColor{Header,Odd,Even} in the :ref:latexsphinxsetup section.

.. note::

  * It is hard-coded in LaTeX that a single cell will obey the row colour
    even if there is a column colour set via :code-tex:`\\columncolor`
    from a column specification (see :rst:dir:`tabularcolumns`).
    Sphinx provides :code-tex:`\\sphinxnorowcolor` which can be used
    in a table column specification like this:

    .. code-block:: latex

       >{\columncolor{blue}\sphinxnorowcolor}

  * Sphinx also provides :code-tex:`\\sphinxcolorblend`,
    which however requires the xcolor_ package.
    Here is an example:

    .. code-block:: latex

       >{\sphinxcolorblend{!95!red}}

    It means that in this column,
    the row colours will be slightly tinted by red;
    refer to xcolor_ documentation for more on the syntax of its
    :code-tex:`\\blendcolors` command
    (a :code-tex:`\\blendcolors` in place of :code-tex:`\\sphinxcolorblend`
    would modify colours of the cell *contents*,
    not of the cell *background colour panel*...).
    You can find an example of usage in the :ref:`dev-deprecated-apis`
    section of this document in PDF format.

    .. hint::

       If you want to use a special colour for the *contents* of the
       cells of a given column use ``>{\noindent\color{<color>}}``,
       possibly in addition to the above.

  * Multi-row merged cells, whether single column or multi-column
    currently ignore any set column, row, or cell colour.

  * It is possible for a simple cell to set a custom colour via the
    :dudir:`raw` directive and
    the :code-tex:`\\cellcolor` LaTeX command used
    anywhere in the cell contents.
    This currently is without effect in a merged cell, whatever its kind.

.. hint::

  In a document not using ``'booktabs'`` globally,
  it is possible to style an individual table via the ``booktabs`` class,
  but it will be necessary to add ``r'\usepackage{booktabs}'``
  to the LaTeX preamble.

  On the other hand one can use ``colorrows`` class for individual tables
  with no extra package (as Sphinx since 5.3.0 always loads colortbl_).

.. _booktabs: https://ctan.org/pkg/booktabs .. _colortbl: https://ctan.org/pkg/colortbl .. _xcolor: https://ctan.org/pkg/xcolor

.. versionadded:: 5.3.0

.. versionchanged:: 6.0.0

  Modify default from :code-py:`[]` to :code-py:`['booktabs', 'colorrows']`.

.. confval:: latex_use_xindy :type: :code-py:bool :default: :code-py:True if latex_engine in {'xelatex', 'lualatex'} else False

Use Xindy_ to prepare the index of general terms. By default, the LaTeX builder uses :program:makeindex for preparing the index of general terms . Using Xindy_ means that words with UTF-8 characters will be ordered correctly for the :confval:language.

.. _Xindy: https://xindy.sourceforge.net/

  • This option is ignored if :confval:latex_engine is :code-py:'platex' (Japanese documents; :program:mendex replaces :program:makeindex then).

  • The default is :code-py:True for :code-py:'xelatex' or :code-py:'lualatex' as :program:makeindex creates .ind files containing invalid bytes for the UTF-8 encoding if any indexed term starts with a non-ASCII character. With :code-py:'lualatex' this then breaks the PDF build.

  • The default is :code-py:False for :code-py:'pdflatex', but :code-py:True is recommended for non-English documents as soon as some indexed terms use non-ASCII characters from the language script. Attempting to index a term whose first character is non-ASCII will break the build, if :confval:latex_use_xindy is left to its default :code-py:False.

Sphinx adds some dedicated support to the :program:xindy base distribution for using :code-py:'pdflatex' engine with Cyrillic scripts. With both :code-py:'pdflatex' and Unicode engines, Cyrillic documents handle the indexing of Latin names correctly, even those having diacritics.

.. versionadded:: 1.8

.. confval:: latex_elements :type: :code-py:dict[str, str] :default: :code-py:{}

.. versionadded:: 0.5

:ref:See the full documentation for latex_elements <latex_elements_confval>.

.. confval:: latex_docclass :type: :code-py:dict[str, str] :default: :code-py:{}

A dictionary mapping :code-py:'howto' and :code-py:'manual' to names of real document classes that will be used as the base for the two Sphinx classes. Default is to use :code-py:'article' for :code-py:'howto' and :code-py:'report' for :code-py:'manual'.

.. versionadded:: 1.0

.. versionchanged:: 1.5 In Japanese documentation (:confval:language is :code-py:'ja'), by default :code-py:'jreport' is used for :code-py:'howto' and :code-py:'jsbook' for :code-py:'manual'.

.. confval:: latex_additional_files :type: :code-py:Sequence[str] :default: :code-py:()

A list of file names, relative to the :term:configuration directory, to copy to the build directory when building LaTeX output. This is useful to copy files that Sphinx doesn't copy automatically, or to overwrite Sphinx LaTeX support files with custom versions. Image files that are referenced in source files (e.g. via .. image::) are copied automatically and should not be listed there.

.. attention:: Filenames with the .tex extension will be automatically handed over to the PDF build process triggered by :option:sphinx-build -M latexpdf <sphinx-build -M> or by :program:make latexpdf. If the file was added only to be :code-tex:\\input{} from a modified preamble, you must add a further suffix such as .txt to the filename and adjust the :code-tex:\\input{} macro accordingly.

.. versionadded:: 0.6

.. versionchanged:: 1.2 This overrides the files provided from Sphinx such as sphinx.sty.

.. confval:: latex_theme :type: :code-py:str :default: :code-py:'manual'

The "theme" that the LaTeX output should use. It is a collection of settings for LaTeX output (e.g. document class, top level sectioning unit and so on).

The bundled first-party LaTeX themes are manual and howto:

manual A LaTeX theme for writing a manual. It imports the report document class (Japanese documents use jsbook).

howto A LaTeX theme for writing an article. It imports the article document class (Japanese documents use jreport). :confval:latex_appendices is only available for this theme.

.. versionadded:: 3.0

.. confval:: latex_theme_options :type: :code-py:dict[str, Any] :default: :code-py:{}

A dictionary of options that influence the look and feel of the selected theme. These are theme-specific.

.. versionadded:: 3.1

.. confval:: latex_theme_path :type: :code-py:list[str] :default: :code-py:[]

A list of paths that contain custom LaTeX themes as subdirectories. Relative paths are taken as relative to the :term:configuration directory.

.. versionadded:: 3.0

.. _text-options:

Options for text output

These options influence text output.

.. confval:: text_add_secnumbers :type: :code-py:bool :default: :code-py:True

Include section numbers in text output.

.. versionadded:: 1.7

.. confval:: text_newlines :type: :code-py:'unix' | 'windows' | 'native' :default: :code-py:'unix'

:code-py:'unix' Use Unix-style line endings (\n). :code-py:'windows' Use Windows-style line endings (\r\n). :code-py:'native' Use the line ending style of the platform the documentation is built on.

.. versionadded:: 1.1

.. confval:: text_secnumber_suffix :type: :code-py:str :default: :code-py:'. '

Suffix for section numbers in text output. Set to :code-py:' ' to suppress the final dot on section numbers.

.. versionadded:: 1.7

.. confval:: text_sectionchars :type: :code-py:str :default: :code-py:'*=-~"+\'`

A string of 7 characters that should be used for underlining sections. The first character is used for first-level headings, the second for second-level headings and so on.

.. versionadded:: 1.1

.. _man-options:

Options for manual page output

These options influence manual page output.

.. confval:: man_pages :type: :code-py:Sequence[tuple[str, str, str, str, str]] :default: The default manual pages

This value determines how to group the document tree into manual pages. It must be a list of tuples (startdocname, name, description, authors, section), where the items are:

startdocname String that specifies the :term:document name of the manual page's master document. All documents referenced by the startdoc document in ToC trees will be included in the manual page. (If you want to use the default master document for your manual pages build, provide your :confval:master_doc here.)

name Name of the manual page. This should be a short string without spaces or special characters. It is used to determine the file name as well as the name of the manual page (in the NAME section).

description Description of the manual page. This is used in the NAME section. Can be an empty string if you do not want to automatically generate the NAME section.

authors A list of strings with authors, or a single string. Can be an empty string or list if you do not want to automatically generate an AUTHORS section in the manual page.

section The manual page section. Used for the output file name as well as in the manual page header.

.. versionadded:: 1.0

.. confval:: man_show_urls :type: :code-py:bool :default: :code-py:False

Add URL addresses after links.

.. versionadded:: 1.1

.. confval:: man_make_section_directory :type: :code-py:bool :default: :code-py:True

Make a section directory on build man page.

.. versionadded:: 3.3

.. versionchanged:: 4.0 The default is now :code-py:False (previously :code-py:True).

.. versionchanged:: 4.0.2 Revert the change in the default.

.. _texinfo-options:

Options for Texinfo output

These options influence Texinfo output.

.. confval:: texinfo_documents :type: :code-py:Sequence[tuple[str, str, str, str, str, str, str, bool]] :default: The default Texinfo documents

This value determines how to group the document tree into Texinfo source files. It must be a list of tuples (startdocname, targetname, title, author, dir_entry, description, category, toctree_only), where the items are:

startdocname String that specifies the :term:document name of the Texinfo file's master document. All documents referenced by the startdoc document in ToC trees will be included in the Texinfo file. (If you want to use the default master document for your Texinfo build, provide your :confval:master_doc here.)

targetname File name (no extension) of the Texinfo file in the output directory.

title Texinfo document title. Can be empty to use the title of the startdoc document. Inserted as Texinfo markup, so special characters like @ and {} will need to be escaped to be inserted literally.

author Author for the Texinfo document. Inserted as Texinfo markup. Use @* to separate multiple authors, as in: 'John@*Sarah'.

dir_entry The name that will appear in the top-level DIR menu file.

description Descriptive text to appear in the top-level DIR menu file.

category Specifies the section which this entry will appear in the top-level DIR menu file.

toctree_only Must be :code-py:True or :code-py:False. If True, the startdoc document itself is not included in the output, only the documents referenced by it via ToC trees. With this option, you can put extra stuff in the master document that shows up in the HTML, but not the Texinfo output.

.. versionadded:: 1.1

.. confval:: texinfo_appendices :type: :code-py:Sequence[str] :default: :code-py:[]

A list of document names to append as an appendix to all manuals.

.. versionadded:: 1.1

.. confval:: texinfo_cross_references :type: :code-py:bool :default: :code-py:True

Generate inline references in a document. Disabling inline references can make an info file more readable with a stand-alone reader (info).

.. versionadded:: 4.4

.. confval:: texinfo_domain_indices :type: :code-py:bool | Sequence[str] :default: :code-py:True

If True, generate domain-specific indices in addition to the general index. For e.g. the Python domain, this is the global module index.

This value can be a Boolean or a list of index names that should be generated. To find out the index name for a specific index, look at the HTML file name. For example, the Python module index has the name 'py-modindex'.

Example:

.. code-block:: python

  texinfo_domain_indices = {
      'py-modindex',
  }

.. versionadded:: 1.1 .. versionchanged:: 7.4 Permit and prefer a set type.

.. confval:: texinfo_elements :type: :code-py:dict[str, Any] :default: :code-py:{}

A dictionary that contains Texinfo snippets that override those that Sphinx usually puts into the generated .texi files.

  • Keys that you may want to override include:

    'paragraphindent' Number of spaces to indent the first line of each paragraph, default 2. Specify 0 for no indentation.

    'exampleindent' Number of spaces to indent the lines for examples or literal blocks, default 4. Specify 0 for no indentation.

    'preamble' Texinfo markup inserted near the beginning of the file.

    'copying' Texinfo markup inserted within the @copying block and displayed after the title. The default value consists of a simple title page identifying the project.

  • Keys that are set by other options and therefore should not be overridden are 'author', 'body', 'date', 'direntry' 'filename', 'project', 'release', and 'title'.

.. versionadded:: 1.1

.. confval:: texinfo_no_detailmenu :type: :code-py:bool :default: :code-py:False

Do not generate a @detailmenu in the "Top" node's menu containing entries for each sub-node in the document.

.. versionadded:: 1.2

.. confval:: texinfo_show_urls :type: :code-py:'footnote' | 'no' | 'inline' :default: :code-py:'footnote'

Control how to display URL addresses. The setting can have the following values:

:code-py:'footnote' Display URLs in footnotes. :code-py:'no' Do not display URLs. :code-py:'inline' Display URLs inline in parentheses.

.. versionadded:: 1.1

.. _qthelp-options:

Options for QtHelp output

These options influence qthelp output. This builder derives from the HTML builder, so the HTML options also apply where appropriate.

.. confval:: qthelp_basename :type: :code-py:str :default: The value of project

The basename for the qthelp file.

.. confval:: qthelp_namespace :type: :code-py:str :default: :code-py:'org.sphinx.{project_name}.{project_version}'

The namespace for the qthelp file.

.. confval:: qthelp_theme :type: :code-py:str :default: :code-py:'nonav'

The HTML theme for the qthelp output.

.. confval:: qthelp_theme_options :type: :code-py:dict[str, Any] :default: :code-py:{}

A dictionary of options that influence the look and feel of the selected theme. These are theme-specific. The options understood by the :ref:builtin themes <builtin-themes> are described :ref:here <builtin-themes>.

Options for XML output

.. confval:: xml_pretty :type: :code-py:bool :default: :code-py:True

Pretty-print the XML.

.. versionadded:: 1.2

Options for the linkcheck builder

Filtering


These options control which links the *linkcheck* builder checks,
and which failures and redirects it ignores.

.. confval:: linkcheck_allowed_redirects
   :type: :code-py:`dict[str, str]`

   A dictionary that maps a pattern of the source URI
   to a pattern of the canonical URI.
   The *linkcheck* builder treats the redirected link as "working" when:

   * the link in the document matches the source URI pattern, and
   * the redirect location matches the canonical URI pattern.

   The *linkcheck* builder will emit a warning when
   it finds redirected links that don't meet the rules above.
   It can be useful to detect unexpected redirects when using
   :option:`the fail-on-warnings mode <sphinx-build --fail-on-warning>`.

   Example:

   .. code-block:: python

      linkcheck_allowed_redirects = {
          # All HTTP redirections from the source URI to
          # the canonical URI will be treated as "working".
          r'https://sphinx-doc\.org/.*': r'https://sphinx-doc\.org/en/master/.*'
      }

   .. versionadded:: 4.1

   .. versionchanged:: 9.0
      Setting :confval:`!linkcheck_allowed_redirects` to an empty dictionary
      may now be used to warn on all redirects encountered
      by the *linkcheck* builder.

.. confval:: linkcheck_anchors
   :type: :code-py:`bool`
   :default: :code-py:`True`

   Check the validity of ``#anchor``\ s in links.
   Since this requires downloading the whole document,
   it is considerably slower when enabled.

   .. versionadded:: 1.2

.. confval:: linkcheck_anchors_ignore
   :type: :code-py:`Sequence[str]`
   :default: :code-py:`["^!"]`

   A list of regular expressions that match anchors that the *linkcheck* builder
   should skip when checking the validity of anchors in links.
   For example, this allows skipping anchors added by a website's JavaScript.

   .. tip::
      Use :confval:`linkcheck_anchors_ignore_for_url` to check a URL,
      but skip verifying that the anchors exist.

   .. note::
      If you want to ignore anchors of a specific page or
      of pages that match a specific pattern
      (but still check occurrences of the same page(s) that don't have anchors),
      use :confval:`linkcheck_ignore` instead,
      for example as follows:

      .. code-block:: python

         linkcheck_ignore = [
            'https://www.sphinx-doc.org/en/1.7/intro.html#',
         ]

   .. versionadded:: 1.5

.. confval:: linkcheck_anchors_ignore_for_url
   :type: :code-py:`Sequence[str]`
   :default: :code-py:`()`

   A list or tuple of regular expressions matching URLs
   for which the *linkcheck* builder should not check the validity of anchors.
   This allows skipping anchor checks on a per-page basis
   while still checking the validity of the page itself.

   .. versionadded:: 7.1

.. confval:: linkcheck_exclude_documents
   :type: :code-py:`Sequence[str]`
   :default: :code-py:`()`

   A list of regular expressions that match documents in which
   the *linkcheck* builder should not check the validity of links.
   This can be used for permitting link decay
   in legacy or historical sections of the documentation.

   Example:

   .. code-block:: python

      # ignore all links in documents located in a subdirectory named 'legacy'
      linkcheck_exclude_documents = [r'.*/legacy/.*']

   .. versionadded:: 4.4

.. confval:: linkcheck_ignore
   :type: :code-py:`Sequence[str]`
   :default: :code-py:`()`

   A list of regular expressions that match URIs that should not be checked
   when doing a ``linkcheck`` build.

   Server-issued redirects that match :confval:`ignored URIs <linkcheck_ignore>`
   will not be followed.

   Example:

   .. code-block:: python

      linkcheck_ignore = [r'https://localhost:\d+/']

   .. versionadded:: 1.1

HTTP Requests

These options control how the linkcheck builder makes HTTP requests, including how it handles redirects and authentication, and the number of workers to use.

.. confval:: linkcheck_auth :type: :code-py:Sequence[tuple[str, Any]] :default: :code-py:[]

Pass authentication information when doing a linkcheck build.

A list of :code-py:(regex_pattern, auth_info) tuples where the items are:

regex_pattern A regular expression that matches a URI. auth_info Authentication information to use for that URI. The value can be anything that is understood by the requests library (see :ref:requests authentication <requests:authentication> for details).

The linkcheck builder will use the first matching auth_info value it can find in the :confval:!linkcheck_auth list, so values earlier in the list have higher priority.

Example:

.. code-block:: python

  linkcheck_auth = [
    ('https://foo\.yourcompany\.com/.+', ('johndoe', 'secret')),
    ('https://.+\.yourcompany\.com/.+', HTTPDigestAuth(...)),
  ]

.. versionadded:: 2.3

.. confval:: linkcheck_allow_unauthorized :type: :code-py:bool :default: :code-py:False

When a webserver responds with an HTTP 401 (unauthorised) response, the current default behaviour of the linkcheck builder is to treat the link as "broken". To change that behaviour, set this option to :code-py:True.

.. versionchanged:: 8.0 The default value for this option changed to :code-py:False, meaning HTTP 401 responses to checked hyperlinks are treated as "broken" by default.

.. versionadded:: 7.3

.. confval:: linkcheck_case_insensitive_urls :type: :code-py:Set[str] | Sequence[str] :default: :code-py:()

A collection of regular expressions that match URLs for which the linkcheck builder should perform case-insensitive comparisons. This is useful for links to websites that are case-insensitive or normalise URL casing.

By default, linkcheck requires the destination URL to match the documented URL case-sensitively. For example, a link to http://example.org/PATH that redirects to http://example.org/path will be reported as redirected.

If the URL matches a pattern contained in :confval:!linkcheck_case_insensitive_urls, it would instead be reported as working.

For example, to treat all GitHub URLs as case-insensitive:

.. code-block:: python

  linkcheck_case_insensitive_urls = [
      r'https://github\.com/.*',
  ]

Or, to treat all URLs as case-insensitive:

.. code-block:: python

  linkcheck_case_insensitive_urls = ['.*']

.. note:: URI fragments (HTML anchors) are not affected by this option. They are always checked with case-sensitive comparisons.

.. versionadded:: 9.0

.. confval:: linkcheck_rate_limit_timeout :type: :code-py:int :default: :code-py:300

The linkcheck builder may issue a large number of requests to the same site over a short period of time. This setting controls the builder behaviour when servers indicate that requests are rate-limited, by setting the maximum duration (in seconds) that the builder will wait for between each attempt before recording a failure.

The linkcheck builder always respects a server's direction of when to retry (using the Retry-After_ header). Otherwise, linkcheck waits for a minute before to retry and keeps doubling the wait time between attempts until it succeeds or exceeds the :confval:!linkcheck_rate_limit_timeout (in seconds). Custom timeouts should be given as a number of seconds.

.. _Retry-After: https://datatracker.ietf.org/doc/html/rfc7231#section-7.1.3

.. versionadded:: 3.4

.. confval:: linkcheck_report_timeouts_as_broken :type: :code-py:bool :default: :code-py:False

If :confval:linkcheck_timeout expires while waiting for a response from a hyperlink, the linkcheck builder will report the link as a timeout by default. To report timeouts as broken instead, you can set :confval:linkcheck_report_timeouts_as_broken to :code-py:True.

.. versionchanged:: 8.0 The default value for this option changed to :code-py:False, meaning timeouts that occur while checking hyperlinks will be reported using the new 'timeout' status code.

.. versionadded:: 7.3

.. confval:: linkcheck_request_headers :type: :code-py:dict[str, dict[str, str]] :default: :code-py:{}

A dictionary that maps URL (without paths) to HTTP request headers.

The key is a URL base string like :code-py:'https://www.sphinx-doc.org/'. To specify headers for other hosts, :code-py:"*" can be used. It matches all hosts only when the URL does not match other settings.

The value is a dictionary that maps header name to its value.

Example:

.. code-block:: python

  linkcheck_request_headers = {
      "https://www.sphinx-doc.org/": {
          "Accept": "text/html",
          "Accept-Encoding": "utf-8",
      },

Domain options

.. _c-config:

Options for the C domain

.. confval:: c_extra_keywords :type: :code-py:Set[str] | Sequence[str] :default: :code-py:['alignas', 'alignof', 'bool', 'complex', 'imaginary', 'noreturn', 'static_assert', 'thread_local']

A list of identifiers to be recognised as keywords by the C parser.

.. versionadded:: 4.0.3 .. versionchanged:: 7.4 :confval:!c_extra_keywords can now be a set.

.. confval:: c_id_attributes :type: :code-py:Sequence[str] :default: :code-py:()

A sequence of strings that the parser should additionally accept as attributes. For example, this can be used when :code-c:#define has been used for attributes, for portability.

Example:

.. code-block:: python

  c_id_attributes = [
      'my_id_attribute',
  ]

.. versionadded:: 3.0 .. versionchanged:: 7.4 :confval:!c_id_attributes can now be a tuple.

.. confval:: c_maximum_signature_line_length :type: :code-py:int | None :default: :code-py:None

If a signature's length in characters exceeds the number set, each parameter within the signature will be displayed on an individual logical line.

When :code-py:None, there is no maximum length and the entire signature will be displayed on a single logical line.

This is a domain-specific setting, overriding :confval:maximum_signature_line_length.

.. versionadded:: 7.1

.. confval:: c_paren_attributes :type: :code-py:Sequence[str] :default: :code-py:()

A sequence of strings that the parser should additionally accept as attributes with one argument. That is, if my_align_as is in the list, then :code-c:my_align_as(X) is parsed as an attribute for all strings X that have balanced braces (:code-c:(), :code-c:[], and :code-c:{}). For example, this can be used when :code-c:#define has been used for attributes, for portability.

Example:

.. code-block:: python

  c_paren_attributes = [
      'my_align_as',
  ]

.. versionadded:: 3.0 .. versionchanged:: 7.4 :confval:!c_paren_attributes can now be a tuple.

.. _cpp-config:

Options for the C++ domain

.. confval:: cpp_id_attributes :type: :code-py:Sequence[str] :default: :code-py:()

A sequence of strings that the parser should additionally accept as attributes. For example, this can be used when :code-cpp:#define has been used for attributes, for portability.

Example:

.. code-block:: python

  cpp_id_attributes = [
      'my_id_attribute',
  ]

.. versionadded:: 1.5 .. versionchanged:: 7.4 :confval:!cpp_id_attributes can now be a tuple.

.. confval:: cpp_index_common_prefix :type: :code-py:Sequence[str] :default: :code-py:()

A list of prefixes that will be ignored when sorting C++ objects in the global index.

Example:

.. code-block:: python

  cpp_index_common_prefix = [
      'awesome_lib::',
  ]

.. versionadded:: 1.5

.. confval:: cpp_maximum_signature_line_length :type: :code-py:int | None :default: :code-py:None

If a signature's length in characters exceeds the number set, each parameter within the signature will be displayed on an individual logical line.

When :code-py:None, there is no maximum length and the entire signature will be displayed on a single logical line.

This is a domain-specific setting, overriding :confval:maximum_signature_line_length.

.. versionadded:: 7.1

.. confval:: cpp_paren_attributes :type: :code-py:Sequence[str] :default: :code-py:()

A sequence of strings that the parser should additionally accept as attributes with one argument. That is, if my_align_as is in the list, then :code-cpp:my_align_as(X) is parsed as an attribute for all strings X that have balanced braces (:code-cpp:(), :code-cpp:[], and :code-cpp:{}). For example, this can be used when :code-cpp:#define has been used for attributes, for portability.

Example:

.. code-block:: python

  cpp_paren_attributes = [
      'my_align_as',
  ]

.. versionadded:: 1.5 .. versionchanged:: 7.4 :confval:!cpp_paren_attributes can now be a tuple.

Options for the Javascript domain

.. confval:: javascript_maximum_signature_line_length :type: :code-py:int | None :default: :code-py:None

If a signature's length in characters exceeds the number set, each parameter within the signature will be displayed on an individual logical line.

When :code-py:None, there is no maximum length and the entire signature will be displayed on a single logical line.

This is a domain-specific setting, overriding :confval:maximum_signature_line_length.

.. versionadded:: 7.1

.. confval:: javascript_trailing_comma_in_multi_line_signatures :type: :code-py:bool :default: :code-py:True

Use a trailing comma in parameter lists spanning multiple lines, if true.

.. versionadded:: 8.2

Options for the Python domain

.. confval:: add_module_names :type: :code-py:bool :default: :code-py:True

A boolean that decides whether module names are prepended to all :term:object names (for object types where a "module" of some kind is defined), e.g. for :rst:dir:py:function directives.

.. confval:: modindex_common_prefix :type: :code-py:list[str] :default: :code-py:[]

A list of prefixes that are ignored for sorting the Python module index (e.g., if this is set to :code-py:['foo.'], then foo.bar is shown under B, not F). This can be handy if you document a project that consists of a single package.

.. caution:: Works only for the HTML builder currently.

.. versionadded:: 0.6

.. confval:: python_display_short_literal_types :type: :code-py:bool :default: :code-py:False

This value controls how :py:data:~typing.Literal types are displayed.

Examples


The examples below use the following :rst:dir:`py:function` directive:

.. code-block:: rst

   .. py:function:: serve_food(item: Literal["egg", "spam", "lobster thermidor"]) -> None

When :code-py:`False`, :py:data:`~typing.Literal` types display as per standard
Python syntax, i.e.:

.. code-block:: python

   serve_food(item: Literal["egg", "spam", "lobster thermidor"]) -> None

When :code-py:`True`, :py:data:`~typing.Literal` types display with a short,
:PEP:`604`-inspired syntax, i.e.:

.. code-block:: python

   serve_food(item: "egg" | "spam" | "lobster thermidor") -> None

.. versionadded:: 6.2

.. confval:: python_maximum_signature_line_length
:type: :code-py:`int | None`
:default: :code-py:`None`

If a signature's length in characters exceeds the number set,
each parameter within the signature will be displayed on
an individual logical line.

When :code-py:`None`, there is no maximum length and the entire
signature will be displayed on a single logical line.

This is a domain-specific setting,
overriding :confval:`maximum_signature_line_length`.

For the Python domain, the signature length depends on whether
the type parameters or the list of arguments are being formatted.
For the former, the signature length ignores the length of the arguments list;
for the latter, the signature length ignores the length of
the type parameters list.

For instance, with :code-py:`python_maximum_signature_line_length = 20`,
only the list of type parameters will be wrapped
while the arguments list will be rendered on a single line

.. code-block:: rst

   .. py:function:: add[T: VERY_LONG_SUPER_TYPE, U: VERY_LONG_SUPER_TYPE](a: T, b: U)

.. versionadded:: 7.1

.. confval:: python_trailing_comma_in_multi_line_signatures
:type: :code-py:`bool`
:default: :code-py:`True`

Use a trailing comma in parameter lists spanning multiple lines, if true.

.. versionadded:: 8.2

.. confval:: python_use_unqualified_type_names
:type: :code-py:`bool`
:default: :code-py:`False`

Suppress the module name of the python reference if it can be resolved.

.. versionadded:: 4.0

.. caution::
   This feature is experimental.

.. confval:: trim_doctest_flags
:type: :code-py:`bool`
:default: :code-py:`True`

Remove doctest flags (comments looking like :code-py:`# doctest: FLAG, ...`)
at the ends of lines and ``<BLANKLINE>`` markers for all code
blocks showing interactive Python sessions (i.e. doctests).
See the extension :mod:`~sphinx.ext.doctest` for more
possibilities of including doctests.

.. versionadded:: 1.0
.. versionchanged:: 1.1
   Now also removes ``<BLANKLINE>``.


Extension options
=================

Extensions frequently have their own configuration options.
Those for Sphinx's first-party extensions are documented
in each :doc:`extension's page </usage/extensions/index>`.
