LaTeX customization =================== .. module:: latex :synopsis: LaTeX specifics. .. _contents: https://docutils.sourceforge.io/docs/ref/rst/directives.html#table-of-contents .. raw:: latex \begingroup \sphinxsetup{% TitleColor={named}{DarkGoldenrod}, pre_border-width=2pt, pre_border-right-width=8pt, pre_padding=5pt, pre_border-radius=5pt, pre_background-TeXcolor={named}{OldLace}, pre_border-TeXcolor=Gold!90, pre_box-shadow=6pt 6pt, pre_box-shadow-TeXcolor=gray!20, % div.warning_border-width=3pt, div.warning_padding=6pt, div.warning_padding-right=18pt, div.warning_padding-bottom=18pt, div.warning_border-TeXcolor=DarkCyan, div.warning_background-TeXcolor=LightCyan, div.warning_box-shadow=-12pt -12pt inset, div.warning_box-shadow-TeXcolor=Cyan, % attentionborder=3pt, attentionBorderColor=Crimson, attentionBgColor=FloralWhite, % noteborder=1pt, noteBorderColor=Olive, noteBgColor=Olive!10, div.note_border-top-width=0pt, div.note_border-bottom-width=0pt, hintBorderColor=LightCoral, } \relax Unlike :ref:`the HTML builders `, the ``latex`` builder does not benefit from prepared themes. The :ref:`latex-options`, and particularly the :ref:`latex_elements ` variable, provides much of the interface for customization. For example: .. code-block:: latex # inside conf.py latex_engine = 'xelatex' latex_elements = { 'fontpkg': r''' \setmainfont{DejaVu Serif} \setsansfont{DejaVu Sans} \setmonofont{DejaVu Sans Mono} ''', 'preamble': r''' \usepackage[titles]{tocloft} \cftsetpnumwidth {1.25cm}\cftsetrmarg{1.5cm} \setlength{\cftchapnumwidth}{0.75cm} \setlength{\cftsecindent}{\cftchapnumwidth} \setlength{\cftsecnumwidth}{1.25cm} ''', 'fncychap': r'\usepackage[Bjornstrup]{fncychap}', 'printindex': r'\footnotesize\raggedright\printindex', } latex_show_urls = 'footnote' .. note:: Keep in mind that backslashes must be doubled in Python string literals to avoid interpretation as escape sequences. Alternatively, you may use raw strings as is done above. .. _latex_elements_confval: The ``latex_elements`` configuration setting -------------------------------------------- A dictionary that contains LaTeX snippets overriding those Sphinx usually puts into the generated ``.tex`` files. Its ``'sphinxsetup'`` key is described :ref:`separately `. It allows also local configurations inserted in generated files, via :dudir:`raw` directives. For example, in the PDF documentation this chapter is styled especially, as will be described later. Keys that you may want to override include: ``'papersize'`` Paper size option of the document class (``'a4paper'`` or ``'letterpaper'``) Default: ``'letterpaper'`` ``'pointsize'`` Point size option of the document class (``'10pt'``, ``'11pt'`` or ``'12pt'``) Default: ``'10pt'`` ``'pxunit'`` The value of the ``px`` when used in image attributes ``width`` and ``height``. The default value is ``'0.75bp'`` which achieves ``96px=1in`` (in TeX ``1in = 72bp = 72.27pt``.) To obtain for example ``100px=1in`` use ``'0.01in'`` or ``'0.7227pt'`` (the latter leads to TeX computing a more precise value, due to the smaller unit used in the specification); for ``72px=1in``, simply use ``'1bp'``; for ``90px=1in``, use ``'0.8bp'`` or ``'0.803pt'``. Default: ``'0.75bp'`` .. versionadded:: 1.5 ``'passoptionstopackages'`` A string which will be positioned early in the preamble, designed to contain ``\\PassOptionsToPackage{options}{foo}`` commands. .. hint:: It may be also used for loading LaTeX packages very early in the preamble. For example package ``fancybox`` is incompatible with being loaded via the ``'preamble'`` key, it must be loaded earlier. Default: ``''`` .. versionadded:: 1.4 ``'babel'`` "babel" package inclusion, default ``'\\usepackage{babel}'`` (the suitable document language string is passed as class option, and ``english`` is used if no language.) For Japanese documents, the default is the empty string. With XeLaTeX and LuaLaTeX, Sphinx configures the LaTeX document to use `polyglossia`_, but one should be aware that current `babel`_ has improved its support for Unicode engines in recent years and for some languages it may make sense to prefer ``babel`` over ``polyglossia``. .. _`polyglossia`: https://ctan.org/pkg/polyglossia .. _`babel`: https://ctan.org/pkg/babel .. hint:: After modifying a core LaTeX key like this one, clean up the LaTeX build repertory before next PDF build, else left-over auxiliary files are likely to break the build. Default: ``'\\usepackage{babel}'`` (``''`` for Japanese documents) .. versionchanged:: 1.5 For :confval:`latex_engine` set to ``'xelatex'``, the default is ``'\\usepackage{polyglossia}\n\\setmainlanguage{}'``. .. versionchanged:: 1.6 ``'lualatex'`` uses same default setting as ``'xelatex'`` .. versionchanged:: 1.7.6 For French, ``xelatex`` and ``lualatex`` default to using ``babel``, not ``polyglossia``. ``'fontpkg'`` Font package inclusion. The default is:: r"""\usepackage{tgtermes} \usepackage{tgheros} \renewcommand\ttdefault{txtt} """ For ``'xelatex'`` and ``'lualatex'`` however the default is to use the GNU FreeFont. .. versionchanged:: 1.2 Defaults to ``''`` when the :confval:`language` uses the Cyrillic script. .. versionchanged:: 2.0 Incorporates some font substitution commands to help support occasional Greek or Cyrillic in a document using ``'pdflatex'`` engine. .. versionchanged:: 4.0.0 - The font substitution commands added at ``2.0`` have been moved to the ``'fontsubstitution'`` key, as their presence here made it complicated for user to customize the value of ``'fontpkg'``. - The default font setting has changed: it still uses Times and Helvetica clones for serif and sans serif, but via better, more complete TeX fonts and associated LaTeX packages. The monospace font has been changed to better match the Times clone. ``'fncychap'`` Inclusion of the "fncychap" package (which makes fancy chapter titles), default ``'\\usepackage[Bjarne]{fncychap}'`` for English documentation (this option is slightly customized by Sphinx), ``'\\usepackage[Sonny]{fncychap}'`` for internationalized docs (because the "Bjarne" style uses numbers spelled out in English). Other "fncychap" styles you can try are "Lenny", "Glenn", "Conny", "Rejne" and "Bjornstrup". You can also set this to ``''`` to disable fncychap. Default: ``'\\usepackage[Bjarne]{fncychap}'`` for English documents, ``'\\usepackage[Sonny]{fncychap}'`` for internationalized documents, and ``''`` for Japanese documents. ``'preamble'`` Additional preamble content. One may move all needed macros into some file :file:`mystyle.tex.txt` of the project source repertory, and get LaTeX to import it at run time:: 'preamble': r'\input{mystyle.tex.txt}', # or, if the \ProvidesPackage LaTeX macro is used in a file mystyle.sty 'preamble': r'\usepackage{mystyle}', It is then needed to set appropriately :confval:`latex_additional_files`, for example: .. code-block:: python latex_additional_files = ["mystyle.sty"] Do not use ``.tex`` as suffix, else the file is submitted itself to the PDF build process, use ``.tex.txt`` or ``.sty`` as in the examples above. Default: ``''`` ``'figure_align'`` Latex figure float alignment. Whenever an image doesn't fit into the current page, it will be 'floated' into the next page but may be preceded by any other text. If you don't like this behavior, use 'H' which will disable floating and position figures strictly in the order they appear in the source. Default: ``'htbp'`` (here, top, bottom, page) .. versionadded:: 1.3 ``'atendofbody'`` Additional document content (right before the indices). Default: ``''`` .. versionadded:: 1.5 ``'extrapackages'`` Additional LaTeX packages. For example: .. code-block:: latex latex_elements = { 'extrapackages': r'\usepackage{isodate}' } The specified LaTeX packages will be loaded before hyperref package and packages loaded from Sphinx extensions. .. hint:: If you'd like to load additional LaTeX packages after hyperref, use ``'preamble'`` key instead. Default: ``''`` .. versionadded:: 2.3 ``'footer'`` Additional footer content (before the indices). Default: ``''`` .. deprecated:: 1.5 Use ``'atendofbody'`` key instead. Keys that don't need to be overridden unless in special cases are: ``'extraclassoptions'`` The default is the empty string. Example: ``'extraclassoptions': 'openany'`` will allow chapters (for documents of the ``'manual'`` type) to start on any page. Default: ``''`` .. versionadded:: 1.2 .. versionchanged:: 1.6 Added this documentation. ``'maxlistdepth'`` LaTeX allows by default at most 6 levels for nesting list and quote-like environments, with at most 4 enumerated lists, and 4 bullet lists. Setting this key for example to ``'10'`` (as a string) will allow up to 10 nested levels (of all sorts). Leaving it to the empty string means to obey the LaTeX default. .. warning:: - Using this key may prove incompatible with some LaTeX packages or special document classes which do their own list customization. - The key setting is silently *ignored* if ``\usepackage{enumitem}`` is executed inside the document preamble. Use then rather the dedicated commands of this LaTeX package. Default: ``6`` .. versionadded:: 1.5 ``'inputenc'`` "inputenc" package inclusion. Default: ``'\\usepackage[utf8]{inputenc}'`` when using pdflatex, else ``''``. .. note:: If using ``utf8x`` in place of ``utf8`` it is mandatory to extend the LaTeX preamble with suitable ``\PreloadUnicodePage{}`` commands, as per the ``utf8x`` documentation (``texdoc ucs`` on a TeXLive based TeX installation). Else, unexpected and possibly hard-to-spot problems (i.e. not causing a build crash) may arise in the PDF, in particular regarding hyperlinks. Even if these precautions are taken, PDF build via ``pdflatex`` engine may crash due to upstream LaTeX not being fully compatible with ``utf8x``. For example, in certain circumstances related to code-blocks, or attempting to include images whose filenames contain Unicode characters. Indeed, starting in 2015, upstream LaTeX with ``pdflatex`` engine has somewhat enhanced native support for Unicode and is becoming more and more incompatible with ``utf8x``. In particular, since the October 2019 LaTeX release, filenames can use Unicode characters, and even spaces. At Sphinx level this means e.g. that the :dudir:`image` and :dudir:`figure` directives are now compatible with such filenames for PDF via LaTeX output. But this is broken if ``utf8x`` is in use. .. versionchanged:: 1.4.3 Previously ``'\\usepackage[utf8]{inputenc}'`` was used for all compilers. ``'cmappkg'`` "cmap" package inclusion. Default: ``'\\usepackage{cmap}'`` .. versionadded:: 1.2 ``'fontenc'`` Customize this from its default ``'\\usepackage[T1]{fontenc}'`` to: - ``'\\usepackage[X2,T1]{fontenc}'`` if you need occasional Cyrillic letters (физика частиц), - ``'\\usepackage[LGR,T1]{fontenc}'`` if you need occasional Greek letters (Σωματιδιακή φυσική). Use ``[LGR,X2,T1]`` rather if both are needed. .. attention:: - Do not use this key for a :confval:`latex_engine` other than ``'pdflatex'``. - If Greek is main language, do not use this key. Since Sphinx 2.2.1, ``xelatex`` will be used automatically as :confval:`latex_engine`. - The TeX installation may need some extra packages. For example, on Ubuntu xenial, packages ``texlive-lang-greek`` and ``cm-super`` are needed for ``LGR`` to work. And ``texlive-lang-cyrillic`` and ``cm-super`` are needed for support of Cyrillic. .. versionchanged:: 1.5 Defaults to ``'\\usepackage{fontspec}'`` when :confval:`latex_engine` is ``'xelatex'``. .. versionchanged:: 1.6 ``'lualatex'`` uses ``fontspec`` per default like ``'xelatex'``. .. versionchanged:: 2.0 ``'lualatex'`` executes ``\defaultfontfeatures[\rmfamily,\sffamily]{}`` to disable TeX ligatures transforming ``<<`` and ``>>`` as escaping working with ``pdflatex/xelatex`` failed with ``lualatex``. .. versionchanged:: 2.0 Detection of ``LGR``, ``T2A``, ``X2`` to trigger support of occasional Greek or Cyrillic letters (``'pdflatex'``). .. versionchanged:: 2.3.0 ``'xelatex'`` executes ``\defaultfontfeatures[\rmfamily,\sffamily]{}`` in order to avoid contractions of ``--`` into en-dash or transforms of straight quotes into curly ones in PDF (in non-literal text paragraphs) despite :confval:`smartquotes` being set to ``False``. ``'fontsubstitution'`` Ignored if ``'fontenc'`` was not configured to use ``LGR`` or ``X2`` (or ``T2A``). In case ``'fontpkg'`` key is configured for usage with some TeX fonts known to be available in the ``LGR`` or ``X2`` encodings, set this one to be the empty string. Else leave to its default. Ignored with :confval:`latex_engine` other than ``'pdflatex'``. .. versionadded:: 4.0.0 ``'textgreek'`` For the support of occasional Greek letters. It is ignored with ``'platex'``, ``'xelatex'`` or ``'lualatex'`` as :confval:`latex_engine` and defaults to either the empty string or to ``'\\usepackage{textalpha}'`` for ``'pdflatex'`` depending on whether the ``'fontenc'`` key was used with ``LGR`` or not. Only expert LaTeX users may want to customize this key. It can also be used as ``r'\usepackage{textalpha,alphabeta}'`` to let ``'pdflatex'`` support Greek Unicode input in :rst:dir:`math` context. For example ``:math:`α``` (U+03B1) will render as :math:`\alpha`. Default: ``'\\usepackage{textalpha}'`` or ``''`` if ``fontenc`` does not include the ``LGR`` option. .. versionadded:: 2.0 ``'geometry'`` "geometry" package inclusion, the default definition is: .. code:: latex '\\usepackage{geometry}' with an additional ``[dvipdfm]`` for Japanese documents. The Sphinx LaTeX style file executes: .. code:: latex \PassOptionsToPackage{hmargin=1in,vmargin=1in,marginpar=0.5in}{geometry} which can be customized via corresponding :ref:`'sphinxsetup' options `. Default: ``'\\usepackage{geometry}'`` (or ``'\\usepackage[dvipdfm]{geometry}'`` for Japanese documents) .. versionadded:: 1.5 .. versionchanged:: 1.5.2 ``dvipdfm`` option if :confval:`latex_engine` is ``'platex'``. .. versionadded:: 1.5.3 The :ref:`'sphinxsetup' keys for the margins `. .. versionchanged:: 1.5.3 The location in the LaTeX file has been moved to after ``\usepackage{sphinx}`` and ``\sphinxsetup{..}``, hence also after insertion of ``'fontpkg'`` key. This is in order to handle the paper layout options in a special way for Japanese documents: the text width will be set to an integer multiple of the *zenkaku* width, and the text height to an integer multiple of the baseline. See the :ref:`hmargin ` documentation for more. ``'hyperref'`` "hyperref" package inclusion; also loads package "hypcap" and issues ``\urlstyle{same}``. This is done after :file:`sphinx.sty` file is loaded and before executing the contents of ``'preamble'`` key. .. attention:: Loading of packages "hyperref" and "hypcap" is mandatory. .. versionadded:: 1.5 Previously this was done from inside :file:`sphinx.sty`. ``'maketitle'`` "maketitle" call. Override if you want to generate a differently styled title page. .. hint:: If the key value is set to ``r'\newcommand\sphinxbackoftitlepage{}\sphinxmaketitle'``, then ```` will be typeset on back of title page (``'manual'`` docclass only). Default: ``'\\sphinxmaketitle'`` .. versionchanged:: 1.8.3 Original ``\maketitle`` from document class is not overwritten, hence is reusable as part of some custom setting for this key. .. versionadded:: 1.8.3 ``\sphinxbackoftitlepage`` optional macro. It can also be defined inside ``'preamble'`` key rather than this one. ``'releasename'`` Value that prefixes ``'release'`` element on title page. As for *title* and *author* used in the tuples of :confval:`latex_documents`, it is inserted as LaTeX markup. Default: ``'Release'`` ``'tableofcontents'`` "tableofcontents" call. The default of ``'\\sphinxtableofcontents'`` is a wrapper of unmodified ``\tableofcontents``, which may itself be customized by user loaded packages. Override if you want to generate a different table of contents or put content between the title page and the TOC. Default: ``'\\sphinxtableofcontents'`` .. versionchanged:: 1.5 Previously the meaning of ``\tableofcontents`` itself was modified by Sphinx. This created an incompatibility with dedicated packages modifying it also such as "tocloft" or "etoc". ``'transition'`` Commands used to display transitions. Override if you want to display transitions differently. Default: ``'\n\n\\bigskip\\hrule\\bigskip\n\n'`` .. versionadded:: 1.2 .. versionchanged:: 1.6 Remove unneeded ``{}`` after ``\\hrule``. ``'makeindex'`` "makeindex" call, the last thing before ``\begin{document}``. With ``'\\usepackage[columns=1]{idxlayout}\\makeindex'`` the index will use only one column. You may have to install ``idxlayout`` LaTeX package. Default: ``'\\makeindex'`` ``'printindex'`` "printindex" call, the last thing in the file. Override if you want to generate the index differently, append some content after the index, or change the font. As LaTeX uses two-column mode for the index it is often advisable to set this key to ``'\\footnotesize\\raggedright\\printindex'``. Or, to obtain a one-column index, use ``'\\def\\twocolumn[#1]{#1}\\printindex'`` (this trick may fail if using a custom document class; then try the ``idxlayout`` approach described in the documentation of the ``'makeindex'`` key). Default: ``'\\printindex'`` ``'fvset'`` Customization of ``fancyvrb`` LaTeX package. The default value is ``'\\fvset{fontsize=auto}'`` which means that the font size will adjust correctly if a code-block ends up in a footnote. You may need to modify this if you use custom fonts: ``'\\fvset{fontsize=\\small}'`` if the monospace font is Courier-like. Default: ``'\\fvset{fontsize=auto}'`` .. versionadded:: 1.8 .. versionchanged:: 2.0 For ``'xelatex'`` and ``'lualatex'`` defaults to ``'\\fvset{fontsize=\\small}'`` as this is adapted to the relative widths of the FreeFont family. .. versionchanged:: 4.0.0 Changed default for ``'pdflatex'``. Previously it was using ``'\\fvset{fontsize=\\small}'``. .. versionchanged:: 4.1.0 Changed default for Chinese documents to ``'\\fvset{fontsize=\\small,formatcom=\\xeCJKVerbAddon}'`` Keys that are set by other options and therefore should not be overridden are: ``'docclass'`` ``'classoptions'`` ``'title'`` ``'release'`` ``'author'`` .. _latexsphinxsetup: The ``sphinxsetup`` configuration setting ----------------------------------------- .. versionadded:: 1.5 The ``'sphinxsetup'`` key of :ref:`latex_elements ` provides a LaTeX-type customization interface:: latex_elements = { 'sphinxsetup': 'key1=value1, key2=value2, ...', } It defaults to empty. If non-empty, it will be passed as argument to the ``\sphinxsetup`` macro inside the document preamble, like this:: \usepackage{sphinx} \sphinxsetup{key1=value1, key2=value2,...} The colors used in the above are provided by the ``svgnames`` option of the "xcolor" package:: latex_elements = { 'passoptionstopackages': r'\PassOptionsToPackage{svgnames}{xcolor}', } It is possible to insert uses of the ``\sphinxsetup`` LaTeX macro directly into the body of the document, via the ``raw`` directive. This chapter is styled in the PDF output using the following insertion at its start. This uses keys described later in :ref:`additionalcss`. .. code-block:: latex .. raw:: latex \begingroup \sphinxsetup{% TitleColor={named}{DarkGoldenrod}, % pre_border-width is 5.1.0 alias for verbatimborder pre_border-width=2pt, pre_border-right-width=8pt, % pre_padding is a 5.1.0 alias for verbatimsep pre_padding=5pt, % Rounded boxes are new at 5.1.0 pre_border-radius=5pt, % TeXcolor reminds that syntax must be as for LaTeX \definecolor pre_background-TeXcolor={named}{OldLace}, % ... and since 5.3.0 also xcolor \colorlet syntax is accepted and we % can thus drop the {named}{...} thing if xcolor is available! pre_border-TeXcolor=Gold, % ... and even take more advantage of xcolor syntax: pre_border-TeXcolor=Gold!90, % add a shadow to code-blocks pre_box-shadow=6pt 6pt, pre_box-shadow-TeXcolor=gray!20, % % This 5.1.0 CSS-named option is alias for warningborder div.warning_border-width=3pt, % Prior to 5.1.0, padding for admonitions was not customizable div.warning_padding=6pt, div.warning_padding-right=18pt, div.warning_padding-bottom=18pt, % Assume xcolor has been loaded with its svgnames option div.warning_border-TeXcolor=DarkCyan, div.warning_background-TeXcolor=LightCyan, % This one is the only option with space separated input: div.warning_box-shadow=-12pt -12pt inset, div.warning_box-shadow-TeXcolor=Cyan, % % The 5.1.0 new name would be div.attention_border-width attentionborder=3pt, % The 5.1.0 name here would be div.attention_border-TeXcolor attentionBorderColor=Crimson, % The 5.1.0 name would be div.attention_background-TeXcolor attentionBgColor=FloralWhite, % % For note/hint/important/tip, the CSS syntax was added at 6.2.0 % Legacy syntax still works noteborder=1pt, noteBorderColor=Olive, % But setting a background color via the new noteBgColor means that % it will be rendered using the same interface as warning type noteBgColor=Olive!10, % We can customize separately the four border-widths, and mimic % the legacy "light" rendering, but now with a background color: % div.note_border-left-width=0pt, % div.note_border-right-width=0pt, % Let's rather for variety use lateral borders: div.note_border-top-width=0pt, div.note_border-bottom-width=0pt, % % As long as only border width and border color are set, *and* using % for this the old interface, the rendering will be the "light" one hintBorderColor=LightCoral, % but if we had used div.hint_border-TeXcolor or *any* CSS-named % option we would have triggered the more complex "heavybox" code. } And this is placed at the end of the chapter source to end the scope of the configuration: .. code-block:: latex .. raw:: latex \endgroup LaTeX syntax for boolean keys requires *lowercase* ``true`` or ``false`` e.g ``'sphinxsetup': "verbatimwrapslines=false"``. If setting the boolean key to ``true``, ``=true`` is optional. Spaces around the commas and equal signs are ignored, spaces inside LaTeX macros may be significant. Do not use quotes to enclose values, whether numerical or strings. ``bookmarksdepth`` Controls the depth of the collapsible bookmarks panel in the PDF. May be either a number (e.g. ``3``) or a LaTeX sectioning name (e.g. ``subsubsection``, i.e. without backslash). For details, refer to the ``hyperref`` LaTeX docs. Default: ``5`` .. versionadded:: 4.0.0 .. _latexsphinxsetuphmargin: ``hmargin, vmargin`` The dimensions of the horizontal (resp. vertical) margins, passed as ``hmargin`` (resp. ``vmargin``) option to the ``geometry`` package. Example:: 'sphinxsetup': 'hmargin={2in,1.5in}, vmargin={1.5in,2in}, marginpar=1in', Japanese documents currently accept only the one-dimension format for these parameters. The ``geometry`` package is then passed suitable options to get the text width set to an exact multiple of the *zenkaku* width, and the text height set to an integer multiple of the baselineskip, with the closest fit for the margins. Default: ``1in`` (equivalent to ``{1in,1in}``) .. hint:: For Japanese ``'manual'`` docclass with pointsize ``11pt`` or ``12pt``, use the ``nomag`` extra document class option (cf. ``'extraclassoptions'`` key of :confval:`latex_elements`) or so-called TeX "true" units:: 'sphinxsetup': 'hmargin=1.5truein, vmargin=1.5truein, marginpar=5zw', .. versionadded:: 1.5.3 ``marginpar`` The ``\marginparwidth`` LaTeX dimension. For Japanese documents, the value is modified to be the closest integer multiple of the *zenkaku* width. Default: ``0.5in`` .. versionadded:: 1.5.3 ``verbatimwithframe`` Boolean to specify if :rst:dir:`code-block`\ s and literal includes are framed. Setting it to ``false`` does not deactivate use of package "framed", because it is still in use for the optional background color. Default: ``true``. ``verbatimwrapslines`` Boolean to specify if long lines in :rst:dir:`code-block`\ 's contents are wrapped. If ``true``, line breaks may happen at spaces (the last space before the line break will be rendered using a special symbol), and at ascii punctuation characters (i.e. not at letters or digits). Whenever a long string has no break points, it is moved to next line. If its length is longer than the line width it will overflow. Default: ``true`` .. _latexsphinxsetupforcewraps: ``verbatimforcewraps`` Boolean to specify if long lines in :rst:dir:`code-block`\ 's contents should be forcefully wrapped to never overflow due to long strings. .. note:: It is assumed that the Pygments_ LaTeXFormatter has not been used with its ``texcomments`` or similar options which allow additional (arbitrary) LaTeX mark-up. Also, in case of :confval:`latex_engine` set to ``'pdflatex'``, only the default LaTeX handling of Unicode code points, i.e. ``utf8`` not ``utf8x`` is allowed. .. _Pygments: https://pygments.org/ Default: ``false`` .. versionadded:: 3.5.0 ``verbatimmaxoverfull`` A number. If an unbreakable long string has length larger than the total linewidth plus this number of characters, and if ``verbatimforcewraps`` mode is on, the input line will be reset using the forceful algorithm which applies breakpoints at each character. Default: ``3`` .. versionadded:: 3.5.0 ``verbatimmaxunderfull`` A number. If ``verbatimforcewraps`` mode applies, and if after applying the line wrapping at spaces and punctuation, the first part of the split line is lacking at least that number of characters to fill the available width, then the input line will be reset using the forceful algorithm. As the default is set to a high value, the forceful algorithm is triggered only in overfull case, i.e. in presence of a string longer than full linewidth. Set this to ``0`` to force all input lines to be hard wrapped at the current available linewidth:: latex_elements = { 'sphinxsetup': "verbatimforcewraps, verbatimmaxunderfull=0", } This can be done locally for a given code-block via the use of raw latex directives to insert suitable ``\sphinxsetup`` (before and after) into the latex file. Default: ``100`` .. versionadded:: 3.5.0 ``verbatimhintsturnover`` Boolean to specify if code-blocks display "continued on next page" and "continued from previous page" hints in case of page breaks. Default: ``true`` .. versionadded:: 1.6.3 .. versionchanged:: 1.7 the default changed from ``false`` to ``true``. ``verbatimcontinuedalign``, ``verbatimcontinuesalign`` Horizontal position relative to the framed contents: either ``l`` (left aligned), ``r`` (right aligned) or ``c`` (centered). Default: ``r`` .. versionadded:: 1.7 ``parsedliteralwraps`` Boolean to specify if long lines in :dudir:`parsed-literal`\ 's contents should wrap. Default: ``true`` .. versionadded:: 1.5.2 set this option value to ``false`` to recover former behavior. ``inlineliteralwraps`` Boolean to specify if line breaks are allowed inside inline literals: but extra potential break-points (additionally to those allowed by LaTeX at spaces or for hyphenation) are currently inserted only after the characters ``. , ; ? ! /`` and ``\``. Due to TeX internals, white space in the line will be stretched (or shrunk) in order to accommodate the linebreak. Default: ``true`` .. versionadded:: 1.5 set this option value to ``false`` to recover former behavior. .. versionchanged:: 2.3.0 added potential breakpoint at ``\`` characters. ``verbatimvisiblespace`` When a long code line is split, the last space character from the source code line right before the linebreak location is typeset using this. Default: ``\textcolor{red}{\textvisiblespace}`` ``verbatimcontinued`` A LaTeX macro inserted at start of continuation code lines. Its (complicated...) default typesets a small red hook pointing to the right:: \makebox[2\fontcharwd\font`\x][r]{\textcolor{red}{\tiny$\hookrightarrow$}} .. versionchanged:: 1.5 The breaking of long code lines was added at 1.4.2. The default definition of the continuation symbol was changed at 1.5 to accommodate various font sizes (e.g. code-blocks can be in footnotes). .. note:: Values for color keys must either: - obey the syntax of the ``\definecolor`` LaTeX command, e.g. something such as ``VerbatimColor={rgb}{0.2,0.3,0.5}`` or ``{RGB}{37,23,255}`` or ``{gray}{0.75}`` or (only with package ``xcolor``) ``{HTML}{808080}`` or ... - or obey the syntax of the ``\colorlet`` command from package ``xcolor`` (which then must exist in the LaTeX installation), e.g. ``VerbatimColor=red!10`` or ``red!50!green`` or ``-red!75`` or ``MyPreviouslyDefinedColor`` or... Refer to xcolor_ documentation for this syntax. .. _xcolor: https://ctan.org/pkg/xcolor .. versionchanged:: 5.3.0 Formerly only the ``\definecolor`` syntax was accepted. ``TitleColor`` The color for titles (as configured via use of package "titlesec".) Default: ``{rgb}{0.126,0.263,0.361}`` ``InnerLinkColor`` A color passed to ``hyperref`` as value of ``linkcolor`` and ``citecolor``. Default: ``{rgb}{0.208,0.374,0.486}``. ``OuterLinkColor`` A color passed to ``hyperref`` as value of ``filecolor``, ``menucolor``, and ``urlcolor``. Default: ``{rgb}{0.216,0.439,0.388}`` ``VerbatimColor`` The background color for :rst:dir:`code-block`\ s. Default: ``{gray}{0.95}`` .. versionchanged:: 6.0.0 Formerly, it was ``{rgb}{1,1,1}`` (white). ``VerbatimBorderColor`` The frame color. Default: ``{RGB}{32,32,32}`` .. versionchanged:: 6.0.0 Formerly it was ``{rgb}{0,0,0}`` (black). ``VerbatimHighlightColor`` The color for highlighted lines. Default: ``{rgb}{0.878,1,1}`` .. versionadded:: 1.6.6 .. _tablecolors: ``TableRowColorHeader`` Sets the background color for (all) the header rows of tables. It will have an effect only if either the :confval:`latex_table_style` contains ``'colorrows'`` or if the table is assigned the ``colorrows`` class. It is ignored for tables with ``nocolorrows`` class. As for the other ``'sphinxsetup'`` keys, it can also be set or modified from a ``\sphinxsetup{...}`` LaTeX command inserted via the :dudir:`raw` directive, or also from a LaTeX environment associated to a `container class `_ and using such ``\sphinxsetup{...}``. Default: ``{gray}{0.86}`` There is also ``TableMergeColorHeader``. If used, sets a specific color for merged single-row cells in the header. .. versionadded:: 5.3.0 ``TableRowColorOdd`` Sets the background color for odd rows in tables (the row count starts at ``1`` at the first non-header row). Has an effect only if the :confval:`latex_table_style` contains ``'colorrows'`` or for specific tables assigned the ``colorrows`` class. Default: ``{gray}{0.92}`` There is also ``TableMergeColorOdd``. .. versionadded:: 5.3.0 ``TableRowColorEven`` Sets the background color for even rows in tables. Default ``{gray}{0.98}`` There is also ``TableMergeColorEven``. .. versionadded:: 5.3.0 ``verbatimsep`` The separation between code lines and the frame. See :ref:`additionalcss` for its alias ``pre_padding`` and additional keys. Default: ``\fboxsep`` ``verbatimborder`` The width of the frame around :rst:dir:`code-block`\ s. See also :ref:`additionalcss` for ``pre_border-width``. Default: ``\fboxrule`` ``shadowsep`` The separation between contents and frame for contents_ and :dudir:`topic` boxes. See :ref:`additionalcss` for the alias ``div.topic_padding``. Default: ``5pt`` ``shadowsize`` The width of the lateral "shadow" to the right and bottom. See :ref:`additionalcss` for ``div.topic_box-shadow`` which allows to configure separately the widths of the vertical and horizontal shadows. Default: ``4pt`` .. versionchanged:: 6.1.2 Fixed a regression introduced at ``5.1.0`` which modified unintentionally the width of topic boxes and worse had made usage of this key break PDF builds. ``shadowrule`` The width of the frame around :dudir:`topic` boxes. See also :ref:`additionalcss` for ``div.topic_border-width``. Default: ``\fboxrule`` |notebdcolors| The color for the two horizontal rules used by Sphinx in LaTeX for styling a :dudir:`note` type admonition. Default: ``{rgb}{0,0,0}`` (black) |notebgcolors| The optional color for the background. It is a priori set to white, but is not used, unless it has been set explicitly, and doing this triggers Sphinx into switching to the more complex LaTeX code which is employed also for ``warning`` type admonitions. There are then additional options which are described in :ref:`additionalcss`. Default: ``{rgb}{1,1,1}`` (white) .. versionadded:: 6.2.0 |notetextcolors| The optional color for the contents. Default: unset (uses ambient text color, a priori black) .. versionadded:: 6.2.0 To be considered experimental until 7.0.0. These options have aliases ``div.note_TeXcolor`` (etc) described in :ref:`additionalcss`. Using the latter will let Sphinx switch to a more complex LaTeX code, which supports the customizability described in :ref:`additionalcss`. |notetexextras| Some extra LaTeX code (such as ``\bfseries`` or ``\footnotesize``) to be executed at start of the contents. Default: empty .. versionadded:: 6.2.0 To be considered experimental until 7.0.0. These options have aliases ``div.note_TeXextras`` (etc) described in :ref:`additionalcss`. ``noteborder``, ``hintborder``, ``importantborder``, ``tipborder`` The width of the two horizontal rules. If the background color is set, or the alternative :ref:`additionalcss` syntax is used (e.g. ``div.note_border-width=1pt`` in place of ``noteborder=1pt``), or *any* option with a CSS-alike name is used, then the border is a full frame and this parameter sets its width also for left and right. Default: ``0.5pt`` .. only:: not latex |warningbdcolors| The color for the admonition frame. Default: ``{rgb}{0,0,0}`` (black) .. only:: latex |wgbdcolorslatex| The color for the admonition frame. Default: ``{rgb}{0,0,0}`` (black) |warningbgcolors| The background colors for the respective admonitions. Default: ``{rgb}{1,1,1}`` (white) |warningborders| The width of the frame. See :ref:`additionalcss` for keys allowing to configure separately each border width. Default: ``1pt`` ``AtStartFootnote`` LaTeX macros inserted at the start of the footnote text at bottom of page, after the footnote number. Default: ``\mbox{ }`` ``BeforeFootnote`` LaTeX macros inserted before the footnote mark. The default removes possible space before it (else, TeX could insert a line break there). Default: ``\leavevmode\unskip`` .. versionadded:: 1.5 ``HeaderFamily`` default ``\sffamily\bfseries``. Sets the font used by headings. .. |notebdcolors| replace:: ``noteBorderColor``, ``hintBorderColor``, ``importantBorderColor``, ``tipBorderColor`` .. |notebgcolors| replace:: ``noteBgColor``, ``hintBgColor``, ``importantBgColor``, ``tipBgColor`` .. |notetextcolors| replace:: ``noteTextColor``, ``hintTextColor``, ``importantTextColor``, ``tipTextColor`` .. |notetexextras| replace:: ``noteTeXextras``, ``hintTeXextras``, ``importantTeXextras``, ``tipTeXextras`` .. |warningbdcolors| replace:: ``warningBorderColor``, ``cautionBorderColor``, ``attentionBorderColor``, ``dangerBorderColor``, ``errorBorderColor`` .. |wgbdcolorslatex| replace:: ``warningBorderColor``, and ``(caution|attention|danger|error)BorderColor`` .. else latex goes into right margin, as it does not hyphenate the names .. |warningbgcolors| replace:: ``warningBgColor``, ``cautionBgColor``, ``attentionBgColor``, ``dangerBgColor``, ``errorBgColor`` .. |warningborders| replace:: ``warningborder``, ``cautionborder``, ``attentionborder``, ``dangerborder``, ``errorborder`` .. _additionalcss: Additional CSS-like ``'sphinxsetup'`` keys ------------------------------------------- .. versionadded:: 5.1.0 For :rst:dir:`code-block`, :dudir:`topic` and contents_ directive, and strong-type admonitions (:dudir:`warning`, :dudir:`error`, ...). .. versionadded:: 6.2.0 Also the :dudir:`note`, :dudir:`hint`, :dudir:`important` and :dudir:`tip` admonitions can be styled this way. Using for them *any* of the listed options will trigger usage of a more complex LaTeX code than the one used per default (``sphinxheavybox`` vs ``sphinxlightbox``). Setting the new ``noteBgColor`` (or ``hintBgColor``, ...) also triggers usage of ``sphinxheavybox`` for :dudir:`note` (or :dudir:`hint`, ...). Perhaps in future these 5.1.0 (and 6.2.0) novel settings will be optionally imported from some genuine CSS external file, but currently they have to be used via the ``'sphinxsetup'`` interface (or the ``\sphinxsetup`` LaTeX command inserted via the :dudir:`raw` directive) and the CSS syntax is only imitated. .. important:: Low-level LaTeX errors causing a build failure can happen if the input syntax is not respected. * In particular colors must be input as for the other color related options previously described, i.e. either in the ``\definecolor`` syntax or, if package ``xcolor`` is available (it is then automatically used) also the ``\colorlet`` syntax:: ... div.warning_border-TeXcolor={rgb}{1,0,0},% (always works) div.error_background-TeXcolor=red!10,% (works only if xcolor is available) ... * A colon in place of the equal sign will break LaTeX. * ``...border-width`` or ``...padding`` expect a *single* dimension: they can not be used so far with space separated dimensions. * ``...top-right-radius`` et al. values may be either a single or *two* space separated dimensions. * Dimension specifications must use TeX units such as ``pt`` or ``cm`` or ``in``. The ``px`` unit is recognized by ``pdflatex`` and ``lualatex`` but not by ``xelatex`` or ``platex``. * It is allowed for such specifications to be so-called "dimensional expressions", e.g. ``\fboxsep+2pt`` or ``0.5\baselineskip`` are valid inputs. The expressions will be evaluated only at the typesetting time. Be careful though if using as in these examples TeX control sequences to double the backslash or to employ a raw Python string for the value of the :ref:`'sphinxsetup' ` key. * As a rule, avoid inserting unneeded spaces in the key values: especially for the radii an input such ``2 pt 3pt`` will break LaTeX. Beware also that ``\fboxsep \fboxsep`` will not be seen as space separated in LaTeX. You must use something such as ``{\fboxsep} \fboxsep``. Or use directly ``3pt 3pt`` which is a priori equivalent and simpler. The options are all named in a similar pattern which depends on a ``prefix``, which is then followed by an underscore, then the property name. .. csv-table:: :header: Directive, Option prefix, LaTeX environment :rst:dir:`code-block`, ``pre``, ``sphinxVerbatim`` :dudir:`topic`, ``div.topic``, ``sphinxShadowBox`` contents_, ``div.topic``, ``sphinxShadowBox`` :dudir:`note`, ``div.note``, ``sphinxnote`` using ``sphinxheavybox`` :dudir:`warning`, ``div.warning``, ``sphinxwarning`` (uses ``sphinxheavybox``) admonition type, ``div.``, ``sphinx`` (using ``sphinxheavybox``) Here are now these options as well as their common defaults. Replace below ```` by the actual prefix as explained above. Don't forget the underscore separating the prefix from the property names. - | ``_border-top-width``, | ``_border-right-width``, | ``_border-bottom-width``, | ``_border-left-width``, | ``_border-width``. The latter can (currently) be only a *single* dimension which then sets all four others. The default is that all those dimensions are equal. They are set to: * ``\fboxrule`` (i.e. a priori ``0.4pt``) for :rst:dir:`code-block`, * ``\fboxrule`` for :dudir:`topic` or contents_ directive, * ``1pt`` for :dudir:`warning` and other "strong" admonitions, * ``0.5pt`` for :dudir:`note` and other "light" admonitions. The framing style of the "lighbox" used for them in absence of usage of CSS-named options will be emulated by the richer "heavybox" if setting ``border-left-width`` and ``border-right-width`` both to ``0pt``. - ``_box-decoration-break`` can be set to either ``clone`` or ``slice`` and configures the behavior at page breaks. It defaults to ``slice`` for :rst:dir:`code-block` (i.e. for ``=pre``) since 6.0.0. For other directives the default is ``clone``. - | ``_padding-top``, | ``_padding-right``, | ``_padding-bottom``, | ``_padding-left``, | ``_padding``. The latter can (currently) be only a *single* dimension which then sets all four others. The default is that all those dimensions are equal. They are set to: * ``\fboxsep`` (i.e. a priori ``3pt``) for :rst:dir:`code-block`, * ``5pt`` for :dudir:`topic` or contents_ directive, * a special value for :dudir:`warning` and other "strong" admonitions, which ensures a backward compatible behavior. .. important:: Prior to 5.1.0 there was no separate customizability of padding for warning-type boxes in PDF via LaTeX output. The sum of padding and border-width (as set for example for :dudir:`warning` by ``warningborder``, now also named ``div.warning_border-width``) was kept to a certain constant value. This limited the border-width to small values else the border could overlap the text contents. This behavior is kept as default. * the same padding behavior is obeyed per default for :dudir:`note` or other "light" admonitions when using ``sphinxheavybox``. - | ``_border-top-left-radius``, | ``_border-top-right-radius``, | ``_border-bottom-right-radius``, | ``_border-bottom-left-radius``, | ``_border-radius``. This last key sets the first four to its assigned value. Each key value can be either a single, or *two*, dimensions which are then space separated. The default is that all four corners are either circular or straight, with common radii: * ``\fboxsep`` (i.e. a priori ``3pt``) for :rst:dir:`code-block` (since 6.0.0). * ``0pt`` for all other directives; this means to use straight corners. See a remark above about traps with spaces in LaTeX. - ``_box-shadow`` is special in so far as it may be: * the ``none`` keyword, * or a single dimension (giving both x-offset and y-offset), * or two dimensions (separated by a space), * or two dimensions followed by the keyword ``inset``. The x-offset and y-offset may be negative. The default is ``none``, *except* for the :dudir:`topic` or contents_ directives, for which it is ``4pt 4pt``, i.e. the shadow has a width of ``4pt`` and extends to the right and below the frame. The lateral shadow then extends into the page right margin. - | ``_border-TeXcolor``, | ``_background-TeXcolor``, | ``_box-shadow-TeXcolor``, | ``_TeXcolor``. These are colors. The shadow color defaults in all cases to ``{rgb}{0,0,0}`` i.e. to black. Since 6.0.0 the border color and background color of :rst:dir:`code-block`, i.e. ``pre`` prefix, default respectively to ``{RGB}{32,32,32}`` and ``{gray}{0.95}``. They previously defaulted to black, respectively white. For all other types, the border color defaults to black and the background color to white. The ``_TeXcolor`` stands for the CSS property "color", i.e. it influences the text color of the contents. As for the three other options, the naming ``TeXcolor`` is to stress that the input syntax is the TeX one for colors not an HTML/CSS one. If package ``xcolor`` is available in the LaTeX installation, one can use directly named colors as key values. Consider passing options such as ``dvipsnames``, ``svgnames`` or ``x11names`` to ``xcolor`` via ``'passoptionstopackages'`` key of :confval:`latex_elements`. If ``_TeXcolor`` is set, a ``\color`` command is inserted at start of the directive contents; for admonitions, this happens after the heading which reproduces the admonition type. - ``_TeXextras``: if set, its value must be some LaTeX command or commands, for example ``\itshape``. These commands will be inserted at the start of the contents; for admonitions, this happens after the heading which reproduces the admonition type. .. note:: - All directives support ``box-decoration-break`` to be set to ``slice``. .. versionchanged:: 6.2.0 Formerly, only :rst:dir:`code-block` did. The default remains ``clone`` for all other directives, but this will probably change at 7.0.0. - The corners of rounded boxes may be elliptical. .. versionchanged:: 6.2.0 Formerly, only circular rounded corners were supported and a rounded corner forced the whole frame to use the same constant width from ``_border-width``. - Inset shadows are incompatible with rounded corners. In case both are specified the inset shadow will simply be ignored. .. versionchanged:: 6.2.0 Formerly it was to the contrary the rounded corners which were ignored in case an inset shadow was specified. - ``_TeXcolor`` and ``_TeXextras`` are new with 6.2.0. Usefulness is doubtful in the case of :rst:dir:`code-block`: - ``pre_TeXcolor`` will influence only the few non-Pygments highlighted tokens; it does color the line numbers, but if one wants to color *only* them one has to go through the ``fancyvrb`` interface. - ``pre_TeXextras=\footnotesize`` for example may be replaced by usage of the :confval:`latex_elements` key ``'fvset'``. For ``'lualatex'`` or ``'xelatex'`` Sphinx includes in the preamble already ``\fvset{fontsize=\small}`` and this induces ``fancyvrb`` into overriding a ``\footnotesize`` coming from ``pre_TeXextras``. One has to use ``pre_TeXextras=\fvset{fontsize=\footnotesize}`` syntax. Simpler to set directly the :confval:`latex_elements` key ``'fvset'``... Consider these options experimental and that some implementation details may change. For example if the ``pre_TeXextras`` LaTeX commands were put by Sphinx in another location it could override the ``'fvset'`` effect, perhaps this is what will be done in a future release. - Rounded boxes are done using the pict2e_ interface to some basic PDF graphics operations. If this LaTeX package can not be found the build will proceed and render all boxes with straight corners. - Elliptic corners use the ellipse_ LaTeX package which extends pict2e_. If this LaTeX package can not be found rounded corners will be circular arcs (or straight if pict2e_ is not available). .. _pict2e: https://ctan.org/pkg/pict2e .. _ellipse: https://ctan.org/pkg/ellipse The following legacy behavior is currently not customizable: - For :rst:dir:`code-block`, padding and border-width and shadow (if one adds one) will go into the margin; the code lines remain at the same place independently of the values of the padding and border-width, except for being shifted vertically of course to not overwrite other text due to the width of the border or external shadow. - For :dudir:`topic` (and contents_) the shadow (if on right) goes into the page margin, but the border and the extra padding are kept within the text area. Same for admonitions. - The contents_ and :dudir:`topic` directives are governed by the same options with ``div.topic`` prefix: the Sphinx LaTeX mark-up uses for both directives the same ``sphinxShadowBox`` environment which has currently no additional branching, contrarily to the ``sphinxadmonition`` environment which branches according to the admonition directive name, e.g. either to ``sphinxnote`` or ``sphinxwarning`` etc... LaTeX macros and environments ----------------------------- The "LaTeX package" file :file:`sphinx.sty` loads various components providing support macros (aka commands), and environments, which are used in the mark-up produced on output from the ``latex`` builder, before conversion to ``pdf`` via the LaTeX toolchain. Also the "LaTeX class" files :file:`sphinxhowto.cls` and :file:`sphinxmanual.cls` define or customize some environments. All of these files can be found in the latex build repertory. Some of these provide facilities not available from pre-existing LaTeX packages and work around LaTeX limitations with lists, table cells, verbatim rendering, footnotes, etc... Others simply define macros with public names to make overwriting their defaults easy via user-added contents to the preamble. We will survey most of those public names here, but defaults have to be looked at in their respective definition files. .. hint:: Sphinx LaTeX support code is split across multiple smaller-sized files. Rather than adding code to the preamble via `latex_elements `_\ [``'preamble'``] it is also possible to replace entirely one of the component files of Sphinx LaTeX code with a custom version, simply by including a modified copy in the project source and adding the filename to the :confval:`latex_additional_files` list. Check the LaTeX build repertory for the filenames and contents. .. versionchanged:: 4.0.0 split of :file:`sphinx.sty` into multiple smaller units, to facilitate customization of many aspects simultaneously. .. _latex-macros: Macros ~~~~~~ - Text styling commands: .. csv-table:: :header: Name, ``maps argument #1 to:`` :align: left :class: longtable :delim: ; ``\sphinxstrong``; ``\textbf{#1}`` ``\sphinxcode``; ``\texttt{#1}`` ``\sphinxbfcode``; ``\textbf{\sphinxcode{#1}}`` ``\sphinxemail``; ``\textsf{#1}`` ``\sphinxtablecontinued``; ``\textsf{#1}`` ``\sphinxtitleref``; ``\emph{#1}`` ``\sphinxmenuselection``; ``\emph{#1}`` ``\sphinxguilabel``; ``\emph{#1}`` ``\sphinxkeyboard``; ``\sphinxcode{#1}`` ``\sphinxaccelerator``; ``\underline{#1}`` ``\sphinxcrossref``; ``\emph{#1}`` ``\sphinxtermref``; ``\emph{#1}`` ``\sphinxsamedocref``; ``\emph{#1}`` ``\sphinxparam``; ``\emph{#1}`` ``\sphinxtypeparam``; ``\emph{#1}`` ``\sphinxoptional``; ``[#1]`` with larger brackets, see source .. versionadded:: 1.4.5 Use of ``\sphinx`` prefixed macro names to limit possibilities of conflict with LaTeX packages. .. versionadded:: 1.8 ``\sphinxguilabel`` .. versionadded:: 3.0 ``\sphinxkeyboard`` .. versionadded:: 6.2.0 ``\sphinxparam``, ``\sphinxsamedocref`` .. versionadded:: 7.1.0 ``\sphinxparamcomma`` which defaults to a comma followed by a space and ``\sphinxparamcommaoneperline`` which is used for one-parameter-per-line signatures (see :confval:`maximum_signature_line_length`). It defaults to ``\texttt{,}`` to make these end-of-line separators more distinctive. Signatures of Python functions are rendered as ``name(parameters)`` or ``name[type parameters](parameters)`` (see :pep:`695`) where the length of ```` is set to ``0pt`` by default. This can be changed via ``\setlength{\sphinxsignaturelistskip}{1ex}`` for instance. - More text styling: .. csv-table:: :header: Name, ``maps argument #1 to:`` :align: left :class: longtable :delim: ; ``\sphinxstyleindexentry``; ``\texttt{#1}`` ``\sphinxstyleindexextra``; ``(\emph{#1})`` (with a space upfront) ``\sphinxstyleindexpageref``; ``, \pageref{#1}`` ``\sphinxstyleindexpagemain``; ``\textbf{#1}`` ``\sphinxstyleindexlettergroup``; ``{\Large\sffamily#1}\nopagebreak\vspace{1mm}`` ``\sphinxstyleindexlettergroupDefault``; check source, too long for here ``\sphinxstyletopictitle``; ``\textbf{#1}\par\medskip`` ``\sphinxstylesidebartitle``; ``\textbf{#1}\par\medskip`` ``\sphinxstyleothertitle``; ``\textbf{#1}`` ``\sphinxstylesidebarsubtitle``; ``~\\\textbf{#1} \smallskip`` ``\sphinxstyletheadfamily``; ``\sffamily`` (*this one has no argument*) ``\sphinxstyleemphasis``; ``\emph{#1}`` ``\sphinxstyleliteralemphasis``; ``\emph{\sphinxcode{#1}}`` ``\sphinxstylestrong``; ``\textbf{#1}`` ``\sphinxstyleliteralstrong``; ``\sphinxbfcode{#1}`` ``\sphinxstyleabbreviation``; ``\textsc{#1}`` ``\sphinxstyleliteralintitle``; ``\sphinxcode{#1}`` ``\sphinxstylecodecontinued``; ``{\footnotesize(#1)}}`` ``\sphinxstylecodecontinues``; ``{\footnotesize(#1)}}`` ``\sphinxstylenotetitle``; ``\sphinxstrong{#1}`` ``\sphinxstylehinttitle``; *idem* ``\sphinxstyleimportanttitle``; *idem* ``\sphinxstyletiptitle``; *idem* ``\sphinxstylewarningtitle``; *idem* ``\sphinxstylecautiontitle``; *idem* ``\sphinxstyleattentiontitle``; *idem* ``\sphinxstyledangertitle``; *idem* ``\sphinxstyleerrortitle``; *idem* ``\sphinxstyleseealsotitle``; ``\sphinxstrong{#1}\par\nopagebreak`` .. versionadded:: 1.5 These macros were formerly hard-coded as non customizable ``\texttt``, ``\emph``, etc... .. versionadded:: 1.6 ``\sphinxstyletheadfamily`` which defaults to ``\sffamily`` and allows multiple paragraphs in header cells of tables. .. versionadded:: 1.6.3 ``\sphinxstylecodecontinued`` and ``\sphinxstylecodecontinues``. .. versionadded:: 1.8 ``\sphinxstyleindexlettergroup``, ``\sphinxstyleindexlettergroupDefault``. .. versionadded:: 6.2.0 ``\sphinxstylenotetitle`` et al. The ``#1`` is the localized name of the directive, with a final colon. Wrap it as ``\sphinxremovefinalcolon{#1}`` if this final colon is to be removed. Examples: .. code-block:: latex \renewcommand\sphinxstylewarningtitle[1]{% \underline{\textbf{\sphinxremovefinalcolon{#1}}}\par } \renewcommand{\sphinxstylenotetitle}[1]{% \textit{\textbf{\sphinxremovefinalcolon{#1}}}\par\nobreak % LaTeX syntax is complex and we would be better off using \hrule. {\parskip0pt\noindent}% \raisebox{1ex}% {\makebox[\linewidth]{\textcolor{sphinxnoteBorderColor}{\dotfill}}} % It is complex to obtain nice vertical spacing for both a paragraph % or a list following up; this set-up is better for a paragraph next. \par\vskip-\parskip } - ``\sphinxtableofcontents``: A wrapper (defined differently in :file:`sphinxhowto.cls` and in :file:`sphinxmanual.cls`) of standard ``\tableofcontents``. The macro ``\sphinxtableofcontentshook`` is executed during its expansion right before ``\tableofcontents`` itself. .. versionchanged:: 1.5 Formerly, the meaning of ``\tableofcontents`` was modified by Sphinx. .. versionchanged:: 2.0 Hard-coded redefinitions of ``\l@section`` and ``\l@subsection`` formerly done during loading of ``'manual'`` docclass are now executed later via ``\sphinxtableofcontentshook``. This macro is also executed by the ``'howto'`` docclass, but defaults to empty with it. .. hint:: If adding to preamble the loading of ``tocloft`` package, also add to preamble ``\renewcommand\sphinxtableofcontentshook{}`` else it will reset ``\l@section`` and ``\l@subsection`` cancelling ``tocloft`` customization. - ``\sphinxmaketitle``: Used as the default setting of the ``'maketitle'`` :confval:`latex_elements` key. Defined in the class files :file:`sphinxmanual.cls` and :file:`sphinxhowto.cls`. .. versionchanged:: 1.8.3 Formerly, ``\maketitle`` from LaTeX document class was modified by Sphinx. - ``\sphinxbackoftitlepage``: For ``'manual'`` docclass, and if it is defined, it gets executed at end of ``\sphinxmaketitle``, before the final ``\clearpage``. Use either the ``'maketitle'`` key or the ``'preamble'`` key of :confval:`latex_elements` to add a custom definition of ``\sphinxbackoftitlepage``. .. versionadded:: 1.8.3 - ``\sphinxcite``: A wrapper of standard ``\cite`` for citation references. .. _sphinxbox: The ``\sphinxbox`` command ~~~~~~~~~~~~~~~~~~~~~~~~~~ .. versionadded:: 6.2.0 The ``\sphinxbox[key=value,...]{inline text}`` command can be used to "box" inline text elements with all the customizability which has been described in :ref:`additionalcss`. It is a LaTeX command with one optional argument, which is a comma-separated list of key=value pairs, as for :ref:`latexsphinxsetup`. Here is the complete list of keys. They don't use any prefix. - ``border-width``, - ``border-top-width``, ``border-right-width``, ``border-bottom-width``, ``border-left-width``, - ``padding``, - ``padding-top``, ``padding-right``, ``padding-bottom``, ``padding-left``, - ``border-radius``, - ``border-top-left-radius``, ``border-top-right-radius``, ``border-bottom-right-radius``, ``border-bottom-left-radius``, - ``box-shadow``, - ``border-TeXcolor``, ``background-TeXcolor``, ``box-shadow-TeXcolor``, ``TeXcolor``, - ``TeXextras``, - and ``addstrut`` which is a boolean key, i.e. to be used as ``addstrut=true``, or ``addstrut`` alone where ``=true`` is omitted, or ``addstrut=false``. This last key is specific to ``\sphinxbox`` and it means to add a ``\strut`` so that heights and depths are equalized across various instances on the same line with varying contents. The default is ``addstrut=false``. .. important:: Perhaps the default will turn into ``addstrut=true`` at 7.0.0 depending on feedback until then. The combination ``addstrut, padding-bottom=0pt, padding-top=1pt`` is often satisfactory. Refer to :ref:`additionalcss` for important syntax information regarding the other keys. The default configuration uses no shadow, a border-width of ``\fboxrule``, a padding of ``\fboxsep``, circular corners with radii ``\fboxsep`` and background and border colors as for the default rendering of code-blocks. When a ``\sphinxbox`` usage is nested within another one, it will ignore the options of the outer one: it first resets all options to their default state as they were prior to applying the outer box options, then it applies its own specific ones. One can modify these defaults via the command ``\sphinxboxsetup{key=value,...}``. The effect is cumulative, if one uses this command multiple times. Here the options are a mandatory argument so are within curly braces, not square brackets. Here is some example of use: .. code-block:: latex latex_elements = { 'preamble': r''' % modify globally the defaults \sphinxboxsetup{border-width=2pt,% border-radius=4pt,% background-TeXcolor=yellow!20} % configure some styling element with some extra specific options: \protected\def\sphinxkeyboard#1{\sphinxbox[border-TeXcolor=green]{\sphinxcode{#1}}} ''', } A utility ``\newsphinxbox`` is provided to create a new boxing macro, say ``\foo`` which will act exactly like ``\sphinxbox`` but with a given extra configuration: .. code-block:: latex % the specific options to \foo are within brackets \newsphinxbox[border-radius=0pt, box-shadow=2pt 2pt]{\foo} % then use this \foo, possibly with some extra options still: \protected\def\sphinxguilabel#1{\foo{#1}} \protected\def\sphinxmenuselection#1{\foo[box-shadow-TeXcolor=gray]{#1}} Boxes rendered with ``\foo`` obey as the ones using directly ``\sphinxbox`` the current configuration as set possibly mid-way in document via ``\sphinxboxsetup`` (from a :dudir:`raw` LaTeX mark-up), the only difference is that they have an initial additional set of default extras. In the above examples, you can probably use ``\renewcommand`` syntax if you prefer it to ``\protected\def`` (with ``[1]`` in place of ``#1`` then). Environments ~~~~~~~~~~~~ - A :dudir:`figure` may have an optional legend with arbitrary body elements: they are rendered in a ``sphinxlegend`` environment. The default definition issues ``\small``, and ends with ``\par``. .. versionadded:: 1.5.6 Formerly, the ``\small`` was hardcoded in LaTeX writer and the ending ``\par`` was lacking. - Environments associated with admonitions: - ``sphinxnote``, - ``sphinxhint``, - ``sphinximportant``, - ``sphinxtip``, - ``sphinxwarning``, - ``sphinxcaution``, - ``sphinxattention``, - ``sphinxdanger``, - ``sphinxerror``. They may be ``\renewenvironment`` 'd individually, and must then be defined with one argument (it is the heading of the notice, for example ``Warning:`` for :dudir:`warning` directive, if English is the document language). Their default definitions use either the *sphinxheavybox* (for the last 5 ones) or the *sphinxlightbox* environments, configured to use the parameters (colors, border thickness) specific to each type, which can be set via ``'sphinxsetup'`` string. .. versionchanged:: 1.5 Use of public environment names, separate customizability of the parameters, such as ``noteBorderColor``, ``noteborder``, ``warningBgColor``, ``warningBorderColor``, ``warningborder``, ... - Environment for the :rst:dir:`seealso` directive: ``sphinxseealso``. It takes one argument which will be the localized string ``See also`` followed with a colon. .. versionadded:: 6.1.0 .. versionchanged:: 6.2.0 Colon made part of the mark-up rather than being inserted by the environment for coherence with how admonitions are handled generally. - The contents_ directive (with ``:local:`` option) and the :dudir:`topic` directive are implemented by environment ``sphinxShadowBox``. .. versionadded:: 1.4.2 Former code refactored into an environment allowing page breaks. .. versionchanged:: 1.5 Options ``shadowsep``, ``shadowsize``, ``shadowrule``. - The literal blocks (via ``::`` or :rst:dir:`code-block`), are implemented using ``sphinxVerbatim`` environment which is a wrapper of ``Verbatim`` environment from package ``fancyvrb.sty``. It adds the handling of the top caption and the wrapping of long lines, and a frame which allows page breaks. Inside tables the used environment is ``sphinxVerbatimintable`` (it does not draw a frame, but allows a caption). .. versionchanged:: 1.5 ``Verbatim`` keeps exact same meaning as in ``fancyvrb.sty`` (also under the name ``OriginalVerbatim``); ``sphinxVerbatimintable`` is used inside tables. .. versionadded:: 1.5 Options ``verbatimwithframe``, ``verbatimwrapslines``, ``verbatimsep``, ``verbatimborder``. .. versionadded:: 1.6.6 Support for ``:emphasize-lines:`` option .. versionadded:: 1.6.6 Easier customizability of the formatting via exposed to user LaTeX macros such as ``\sphinxVerbatimHighlightLine``. - The bibliography uses ``sphinxthebibliography`` and the Python Module index as well as the general index both use ``sphinxtheindex``; these environments are wrappers of the ``thebibliography`` and respectively ``theindex`` environments as provided by the document class (or packages). .. versionchanged:: 1.5 Formerly, the original environments were modified by Sphinx. Miscellany ~~~~~~~~~~ - Every text paragraph in document body starts with ``\sphinxAtStartPar``. Currently, this is used to insert a zero width horizontal skip which is a trick to allow TeX hyphenation of the first word of a paragraph in a narrow context (like a table cell). For ``'lualatex'`` which does not need the trick, the ``\sphinxAtStartPar`` does nothing. .. versionadded:: 3.5.0 - The section, subsection, ... headings are set using *titlesec*'s ``\titleformat`` command. - For the ``'manual'`` docclass, the chapter headings can be customized using *fncychap*'s commands ``\ChNameVar``, ``\ChNumVar``, ``\ChTitleVar``. File :file:`sphinx.sty` has custom re-definitions in case of *fncychap* option ``Bjarne``. .. versionchanged:: 1.5 Formerly, use of *fncychap* with other styles than ``Bjarne`` was dysfunctional. .. _latexcontainer: - Docutils :dudir:`container` directives are supported in LaTeX output: to let a container class with name ``foo`` influence the final PDF via LaTeX, it is only needed to define in the preamble an environment ``sphinxclassfoo``. A simple example would be: .. code-block:: latex \newenvironment{sphinxclassred}{\color{red}}{} Currently the class names must contain only ascii characters and avoid characters special to LaTeX such as ``\``. .. versionadded:: 4.1.0 .. hint:: As an experimental feature, Sphinx can use user-defined template file for LaTeX source if you have a file named ``_templates/latex.tex_t`` in your project. Additional files ``longtable.tex_t``, ``tabulary.tex_t`` and ``tabular.tex_t`` can be added to ``_templates/`` to configure some aspects of table rendering (such as the caption position). .. versionadded:: 1.6 currently all template variables are unstable and undocumented. .. raw:: latex \endgroup
