.. highlight:: rest Miscellaneous markup ==================== .. _metadata: File-wide metadata ------------------ reST has the concept of "field lists"; these are a sequence of fields marked up like this:: :fieldname: Field content A field list near the top of a file is parsed by docutils as the "docinfo" which is normally used to record the author, date of publication and other metadata. *In Sphinx*, a field list preceding any other markup is moved from the docinfo to the Sphinx environment as document metadata and is not displayed in the output; a field list appearing after the document title will be part of the docinfo as normal and will be displayed in the output. At the moment, these metadata fields are recognized: ``tocdepth`` The maximum depth for a table of contents of this file. .. versionadded:: 0.4 ``nocomments`` If set, the web application won't display a comment form for a page generated from this source file. ``orphan`` If set, warnings about this file not being included in any toctree will be suppressed. .. versionadded:: 1.0 Meta-information markup ----------------------- .. rst:directive:: .. sectionauthor:: name Identifies the author of the current section. The argument should include the author's name such that it can be used for presentation and email address. The domain name portion of the address should be lower case. Example:: .. sectionauthor:: Guido van Rossum By default, this markup isn't reflected in the output in any way (it helps keep track of contributions), but you can set the configuration value :confval:`show_authors` to True to make them produce a paragraph in the output. .. rst:directive:: .. codeauthor:: name The :rst:dir:`codeauthor` directive, which can appear multiple times, names the authors of the described code, just like :rst:dir:`sectionauthor` names the author(s) of a piece of documentation. It too only produces output if the :confval:`show_authors` configuration value is True. Index-generating markup ----------------------- Sphinx automatically creates index entries from all object descriptions (like functions, classes or attributes) like discussed in :ref:`domains`. However, there is also explicit markup available, to make the index more comprehensive and enable index entries in documents where information is not mainly contained in information units, such as the language reference. .. rst:directive:: .. index:: This directive contains one or more index entries. Each entry consists of a type and a value, separated by a colon. For example:: .. index:: single: execution; context module: __main__ module: sys triple: module; search; path The execution context --------------------- ... This directive contains five entries, which will be converted to entries in the generated index which link to the exact location of the index statement (or, in case of offline media, the corresponding page number). Since index directives generate cross-reference targets at their location in the source, it makes sense to put them *before* the thing they refer to -- e.g. a heading, as in the example above. The possible entry types are: single Creates a single index entry. Can be made a subentry by separating the subentry text with a semicolon (this notation is also used below to describe what entries are created). pair ``pair: loop; statement`` is a shortcut that creates two index entries, namely ``loop; statement`` and ``statement; loop``. triple Likewise, ``triple: module; search; path`` is a shortcut that creates three index entries, which are ``module; search path``, ``search; path, module`` and ``path; module search``. see ``see: entry; other`` creates an index entry that refers from ``entry`` to ``other``. seealso Like ``see``, but inserts "see also" instead of "see". module, keyword, operator, object, exception, statement, builtin These all create two index entries. For example, ``module: hashlib`` creates the entries ``module; hashlib`` and ``hashlib; module``. (These are Python-specific and therefore deprecated.) You can mark up "main" index entries by prefixing them with an exclamation mark. The references to "main" entries are emphasized in the generated index. For example, if two pages contain :: .. index:: Python and one page contains :: .. index:: ! Python then the backlink to the latter page is emphasized among the three backlinks. For index directives containing only "single" entries, there is a shorthand notation:: .. index:: BNF, grammar, syntax, notation This creates four index entries. .. versionchanged:: 1.1 Added ``see`` and ``seealso`` types, as well as marking main entries. .. rst:role:: index While the :rst:dir:`index` directive is a block-level markup and links to the beginning of the next paragraph, there is also a corresponding role that sets the link target directly where it is used. The content of the role can be a simple phrase, which is then kept in the text and used as an index entry. It can also be a combination of text and index entry, styled like with explicit targets of cross-references. In that case, the "target" part can be a full entry as described for the directive above. For example:: This is a normal reST :index:`paragraph` that contains several :index:`index entries `. .. versionadded:: 1.1 .. _tags: Including content based on tags ------------------------------- .. rst:directive:: .. only:: Include the content of the directive only if the *expression* is true. The expression should consist of tags, like this:: .. only:: html and draft Undefined tags are false, defined tags (via the ``-t`` command-line option or within :file:`conf.py`) are true. Boolean expressions, also using parentheses (like ``html and (latex or draft)``) are supported. The format of the current builder (``html``, ``latex`` or ``text``) is always set as a tag. .. note:: Due to docutils' specifics of parsing of directive content, you cannot put a section with the same level as the main document heading inside an ``only`` directive. Such sections will appear to be ignored in the parsed document. .. versionadded:: 0.6 Tables ------ Use :ref:`standard reStructuredText tables `. They work fine in HTML output, however there are some gotchas when using tables in LaTeX: the column width is hard to determine correctly automatically. For this reason, the following directive exists: .. rst:directive:: .. tabularcolumns:: column spec This directive gives a "column spec" for the next table occurring in the source file. The spec is the second argument to the LaTeX ``tabulary`` package's environment (which Sphinx uses to translate tables). It can have values like :: |l|l|l| which means three left-adjusted, nonbreaking columns. For columns with longer text that should automatically be broken, use either the standard ``p{width}`` construct, or tabulary's automatic specifiers: +-----+------------------------------------------+ |``L``| ragged-left column with automatic width | +-----+------------------------------------------+ |``R``| ragged-right column with automatic width | +-----+------------------------------------------+ |``C``| centered column with automatic width | +-----+------------------------------------------+ |``J``| justified column with automatic width | +-----+------------------------------------------+ The automatic width is determined by rendering the content in the table, and scaling them according to their share of the total width. By default, Sphinx uses a table layout with ``L`` for every column. .. versionadded:: 0.3 .. warning:: Tables that contain list-like elements such as object descriptions, blockquotes or any kind of lists cannot be set out of the box with ``tabulary``. They are therefore set with the standard LaTeX ``tabular`` environment if you don't give a ``tabularcolumns`` directive. If you do, the table will be set with ``tabulary``, but you must use the ``p{width}`` construct for the columns that contain these elements. Literal blocks do not work with ``tabulary`` at all, so tables containing a literal block are always set with ``tabular``. Also, the verbatim environment used for literal blocks only works in ``p{width}`` columns, which means that by default, Sphinx generates such column specs for such tables. Use the :rst:dir:`tabularcolumns` directive to get finer control over such tables.
