reStructuredText Primer
|
|
=======================
|
|
|
|
This section is a brief introduction to reStructuredText (reST) concepts and
|
|
syntax, intended to provide authors with enough information to author documents
|
|
productively. Since reST was designed to be a simple, unobtrusive markup
|
|
language, this will not take too long.
|
|
|
|
.. seealso::
|
|
|
|
The authoritative `reStructuredText User Documentation
|
|
<http://docutils.sourceforge.net/rst.html>`_. The "ref" links in this
|
|
document link to the description of the individual constructs in the reST
|
|
reference.
|
|
|
|
|
|
Paragraphs
|
|
----------
|
|
|
|
The paragraph (:duref:`ref <paragraphs>`) is the most basic block in a reST
|
|
document. Paragraphs are simply chunks of text separated by one or more blank
|
|
lines. As in Python, indentation is significant in reST, so all lines of the
|
|
same paragraph must be left-aligned to the same level of indentation.
|
|
|
|
|
|
.. _inlinemarkup:
|
|
|
|
Inline markup
|
|
-------------
|
|
|
|
The standard reST inline markup is quite simple: use
|
|
|
|
* one asterisk: ``*text*`` for emphasis (italics),
|
|
* two asterisks: ``**text**`` for strong emphasis (boldface), and
|
|
* backquotes: ````text```` for code samples.
|
|
|
|
If asterisks or backquotes appear in running text and could be confused with
|
|
inline markup delimiters, they have to be escaped with a backslash.
|
|
|
|
Be aware of some restrictions of this markup:
|
|
|
|
* it may not be nested,
|
|
* content may not start or end with whitespace: ``* text*`` is wrong,
|
|
* it must be separated from surrounding text by non-word characters. Use a
|
|
backslash escaped space to work around that: ``thisis\ *one*\ word``.
|
|
|
|
These restrictions may be lifted in future versions of the docutils.
|
|
|
|
reST also allows for custom "interpreted text roles"', which signify that the
|
|
enclosed text should be interpreted in a specific way. Sphinx uses this to
|
|
provide semantic markup and cross-referencing of identifiers, as described in
|
|
the appropriate section. The general syntax is ``:rolename:`content```.
|
|
|
|
Standard reST provides the following roles:
|
|
|
|
* :durole:`emphasis` -- alternate spelling for ``*emphasis*``
|
|
* :durole:`strong` -- alternate spelling for ``**strong**``
|
|
* :durole:`literal` -- alternate spelling for ````literal````
|
|
* :durole:`subscript` -- subscript text
|
|
* :durole:`superscript` -- superscript text
|
|
* :durole:`title-reference` -- for titles of books, periodicals, and other
|
|
materials
|
|
|
|
See :ref:`inline-markup` for roles added by Sphinx.
|
|
|
|
|
|
Lists and Quote-like blocks
|
|
---------------------------
|
|
|
|
List markup (:duref:`ref <bullet-lists>`) is natural: just place an asterisk at
|
|
the start of a paragraph and indent properly. The same goes for numbered lists;
|
|
they can also be autonumbered using a ``#`` sign::
|
|
|
|
* This is a bulleted list.
|
|
* It has two items, the second
|
|
item uses two lines.
|
|
|
|
1. This is a numbered list.
|
|
2. It has two items too.
|
|
|
|
#. This is a numbered list.
|
|
#. It has two items too.
|
|
|
|
|
|
Nested lists are possible, but be aware that they must be separated from the
|
|
parent list items by blank lines::
|
|
|
|
* this is
|
|
* a list
|
|
|
|
* with a nested list
|
|
* and some subitems
|
|
|
|
* and here the parent list continues
|
|
|
|
Definition lists (:duref:`ref <definition-lists>`) are created as follows::
|
|
|
|
term (up to a line of text)
|
|
Definition of the term, which must be indented
|
|
|
|
and can even consist of multiple paragraphs
|
|
|
|
next term
|
|
Description.
|
|
|
|
Note that the term cannot have more than one line of text.
|
|
|
|
Quoted paragraphs (:duref:`ref <block-quotes>`) are created by just indenting
|
|
them more than the surrounding paragraphs.
|
|
|
|
Line blocks (:duref:`ref <line-blocks>`) are a way of preserving line breaks::
|
|
|
|
| These lines are
|
|
| broken exactly like in
|
|
| the source file.
|
|
|
|
There are also several more special blocks available:
|
|
|
|
* field lists (:duref:`ref <field-lists>`)
|
|
* option lists (:duref:`ref <option-lists>`)
|
|
* quoted literal blocks (:duref:`ref <quoted-literal-blocks>`)
|
|
* doctest blocks (:duref:`ref <doctest-blocks>`)
|
|
|
|
|
|
Source Code
|
|
-----------
|
|
|
|
Literal code blocks (:duref:`ref <literal-blocks>`) are introduced by ending a
|
|
paragraph with the special marker ``::``. The literal block must be indented
|
|
(and, like all paragraphs, separated from the surrounding ones by blank lines)::
|
|
|
|
This is a normal text paragraph. The next paragraph is a code sample::
|
|
|
|
It is not processed in any way, except
|
|
that the indentation is removed.
|
|
|
|
It can span multiple lines.
|
|
|
|
This is a normal text paragraph again.
|
|
|
|
The handling of the ``::`` marker is smart:
|
|
|
|
* If it occurs as a paragraph of its own, that paragraph is completely left
|
|
out of the document.
|
|
* If it is preceded by whitespace, the marker is removed.
|
|
* If it is preceded by non-whitespace, the marker is replaced by a single
|
|
colon.
|
|
|
|
That way, the second sentence in the above example's first paragraph would be
|
|
rendered as "The next paragraph is a code sample:".
|
|
|
|
|
|
.. _rst-tables:
|
|
|
|
Tables
|
|
------
|
|
|
|
Two forms of tables are supported. For *grid tables* (:duref:`ref
|
|
<grid-tables>`), you have to "paint" the cell grid yourself. They look like
|
|
this::
|
|
|
|
+------------------------+------------+----------+----------+
|
|
| Header row, column 1 | Header 2 | Header 3 | Header 4 |
|
|
| (header rows optional) | | | |
|
|
+========================+============+==========+==========+
|
|
| body row 1, column 1 | column 2 | column 3 | column 4 |
|
|
+------------------------+------------+----------+----------+
|
|
| body row 2 | ... | ... | |
|
|
+------------------------+------------+----------+----------+
|
|
|
|
*Simple tables* (:duref:`ref <simple-tables>`) are easier to write, but
|
|
limited: they must contain more than one row, and the first column cannot
|
|
contain multiple lines. They look like this::
|
|
|
|
===== ===== =======
|
|
A B A and B
|
|
===== ===== =======
|
|
False False False
|
|
True False False
|
|
False True False
|
|
True True True
|
|
===== ===== =======
|
|
|
|
|
|
Hyperlinks
|
|
----------
|
|
|
|
External links
|
|
^^^^^^^^^^^^^^
|
|
|
|
Use ```Link text <http://example.com/>`_`` for inline web links. If the link
|
|
text should be the web address, you don't need special markup at all, the parser
|
|
finds links and mail addresses in ordinary text.
|
|
|
|
You can also separate the link and the target definition (:duref:`ref
|
|
<hyperlink-targets>`), like this::
|
|
|
|
This is a paragraph that contains `a link`_.
|
|
|
|
.. _a link: http://example.com/
|
|
|
|
|
|
Internal links
|
|
^^^^^^^^^^^^^^
|
|
|
|
Internal linking is done via a special reST role provided by Sphinx, see the
|
|
section on specific markup, :ref:`ref-role`.
|
|
|
|
|
|
Sections
|
|
--------
|
|
|
|
Section headers (:duref:`ref <sections>`) are created by underlining (and
|
|
optionally overlining) the section title with a punctuation character, at least
|
|
as long as the text::
|
|
|
|
=================
|
|
This is a heading
|
|
=================
|
|
|
|
Normally, there are no heading levels assigned to certain characters as the
|
|
structure is determined from the succession of headings. However, for the
|
|
Python documentation, this convention is used which you may follow:
|
|
|
|
* ``#`` with overline, for parts
|
|
* ``*`` with overline, for chapters
|
|
* ``=``, for sections
|
|
* ``-``, for subsections
|
|
* ``^``, for subsubsections
|
|
* ``"``, for paragraphs
|
|
|
|
Of course, you are free to use your own marker characters (see the reST
|
|
documentation), and use a deeper nesting level, but keep in mind that most
|
|
target formats (HTML, LaTeX) have a limited supported nesting depth.
|
|
|
|
|
|
Explicit Markup
|
|
---------------
|
|
|
|
"Explicit markup" (:duref:`ref <explicit-markup-blocks>`) is used in reST for
|
|
most constructs that need special handling, such as footnotes,
|
|
specially-highlighted paragraphs, comments, and generic directives.
|
|
|
|
An explicit markup block begins with a line starting with ``..`` followed by
|
|
whitespace and is terminated by the next paragraph at the same level of
|
|
indentation. (There needs to be a blank line between explicit markup and normal
|
|
paragraphs. This may all sound a bit complicated, but it is intuitive enough
|
|
when you write it.)
|
|
|
|
|
|
.. _directives:
|
|
|
|
Directives
|
|
----------
|
|
|
|
A directive (:duref:`ref <directives>`) is a generic block of explicit markup.
|
|
Besides roles, it is one of the extension mechanisms of reST, and Sphinx makes
|
|
heavy use of it.
|
|
|
|
Docutils supports the following directives:
|
|
|
|
* Admonitions: :dudir:`attention`, :dudir:`caution`, :dudir:`danger`,
|
|
:dudir:`error`, :dudir:`hint`, :dudir:`important`, :dudir:`note`,
|
|
:dudir:`tip`, :dudir:`warning` and the generic :dudir:`admonition`.
|
|
(Most themes style only "note" and "warning" specially.)
|
|
|
|
* Images:
|
|
|
|
- :dudir:`image` (see also Images_ below)
|
|
- :dudir:`figure` (an image with caption and optional legend)
|
|
|
|
* Additional body elements:
|
|
|
|
- :dudir:`contents` (a local, i.e. for the current file only, table of
|
|
contents)
|
|
- :dudir:`container` (a container with a custom class, useful to generate an
|
|
outer ``<div>`` in HTML)
|
|
- :dudir:`rubric` (a heading without relation to the document sectioning)
|
|
- :dudir:`topic`, :dudir:`sidebar` (special highlighted body elements)
|
|
- :dudir:`parsed-literal` (literal block that supports inline markup)
|
|
- :dudir:`epigraph` (a block quote with optional attribution line)
|
|
- :dudir:`highlights`, :dudir:`pull-quote` (block quotes with their own
|
|
class attribute)
|
|
- :dudir:`compound` (a compound paragraph)
|
|
|
|
* Special tables:
|
|
|
|
- :dudir:`table` (a table with title)
|
|
- :dudir:`csv-table` (a table generated from comma-separated values)
|
|
- :dudir:`list-table` (a table generated from a list of lists)
|
|
|
|
* Special directives:
|
|
|
|
- :dudir:`raw` (include raw target-format markup)
|
|
- :dudir:`include` (include reStructuredText from another file)
|
|
-- in Sphinx, when given an absolute include file path, this directive takes
|
|
it as relative to the source directory
|
|
- :dudir:`class` (assign a class attribute to the next element) [1]_
|
|
|
|
* HTML specifics:
|
|
|
|
- :dudir:`meta` (generation of HTML ``<meta>`` tags)
|
|
- :dudir:`title` (override document title)
|
|
|
|
* Influencing markup:
|
|
|
|
- :dudir:`default-role` (set a new default role)
|
|
- :dudir:`role` (create a new role)
|
|
|
|
Since these are only per-file, better use Sphinx' facilities for setting the
|
|
:confval:`default_role`.
|
|
|
|
Do *not* use the directives :dudir:`sectnum`, :dudir:`header` and
|
|
:dudir:`footer`.
|
|
|
|
Directives added by Sphinx are described in :ref:`sphinxmarkup`.
|
|
|
|
Basically, a directive consists of a name, arguments, options and content. (Keep
|
|
this terminology in mind, it is used in the next chapter describing custom
|
|
directives.) Looking at this example, ::
|
|
|
|
.. function:: foo(x)
|
|
foo(y, z)
|
|
:module: some.module.name
|
|
|
|
Return a line of text input from the user.
|
|
|
|
``function`` is the directive name. It is given two arguments here, the
|
|
remainder of the first line and the second line, as well as one option
|
|
``module`` (as you can see, options are given in the lines immediately following
|
|
the arguments and indicated by the colons). Options must be indented to the
|
|
same level as the directive content.
|
|
|
|
The directive content follows after a blank line and is indented relative to the
|
|
directive start.
|
|
|
|
|
|
Images
|
|
------
|
|
|
|
reST supports an image directive (:dudir:`ref <image>`), used like so::
|
|
|
|
.. image:: gnu.png
|
|
(options)
|
|
|
|
When used within Sphinx, the file name given (here ``gnu.png``) must either be
|
|
relative to the source file, or absolute which means that they are relative to
|
|
the top source directory. For example, the file ``sketch/spam.rst`` could refer
|
|
to the image ``images/spam.png`` as ``../images/spam.png`` or
|
|
``/images/spam.png``.
|
|
|
|
Sphinx will automatically copy image files over to a subdirectory of the output
|
|
directory on building (e.g. the ``_static`` directory for HTML output.)
|
|
|
|
Interpretation of image size options (``width`` and ``height``) is as follows:
|
|
if the size has no unit or the unit is pixels, the given size will only be
|
|
respected for output channels that support pixels (i.e. not in LaTeX output).
|
|
Other units (like ``pt`` for points) will be used for HTML and LaTeX output.
|
|
|
|
Sphinx extends the standard docutils behavior by allowing an asterisk for the
|
|
extension::
|
|
|
|
.. image:: gnu.*
|
|
|
|
Sphinx then searches for all images matching the provided pattern and determines
|
|
their type. Each builder then chooses the best image out of these candidates.
|
|
For instance, if the file name ``gnu.*`` was given and two files :file:`gnu.pdf`
|
|
and :file:`gnu.png` existed in the source tree, the LaTeX builder would choose
|
|
the former, while the HTML builder would prefer the latter.
|
|
|
|
.. versionchanged:: 0.4
|
|
Added the support for file names ending in an asterisk.
|
|
|
|
.. versionchanged:: 0.6
|
|
Image paths can now be absolute.
|
|
|
|
|
|
Footnotes
|
|
---------
|
|
|
|
For footnotes (:duref:`ref <footnotes>`), use ``[#name]_`` to mark the footnote
|
|
location, and add the footnote body at the bottom of the document after a
|
|
"Footnotes" rubric heading, like so::
|
|
|
|
Lorem ipsum [#f1]_ dolor sit amet ... [#f2]_
|
|
|
|
.. rubric:: Footnotes
|
|
|
|
.. [#f1] Text of the first footnote.
|
|
.. [#f2] Text of the second footnote.
|
|
|
|
You can also explicitly number the footnotes (``[1]_``) or use auto-numbered
|
|
footnotes without names (``[#]_``).
|
|
|
|
|
|
Citations
|
|
---------
|
|
|
|
Standard reST citations (:duref:`ref <citations>`) are supported, with the
|
|
additional feature that they are "global", i.e. all citations can be referenced
|
|
from all files. Use them like so::
|
|
|
|
Lorem ipsum [Ref]_ dolor sit amet.
|
|
|
|
.. [Ref] Book or article reference, URL or whatever.
|
|
|
|
Citation usage is similar to footnote usage, but with a label that is not
|
|
numeric or begins with ``#``.
|
|
|
|
|
|
Substitutions
|
|
-------------
|
|
|
|
reST supports "substitutions" (:duref:`ref <substitution-definitions>`), which
|
|
are pieces of text and/or markup referred to in the text by ``|name|``. They
|
|
are defined like footnotes with explicit markup blocks, like this::
|
|
|
|
.. |name| replace:: replacement *text*
|
|
|
|
or this::
|
|
|
|
.. |caution| image:: warning.png
|
|
:alt: Warning!
|
|
|
|
See the :duref:`reST reference for substitutions <substitution-definitions>`
|
|
for details.
|
|
|
|
If you want to use some substitutions for all documents, put them into
|
|
:confval:`rst_prolog` or put them into a separate file and include it into all
|
|
documents you want to use them in, using the :rst:dir:`include` directive. (Be
|
|
sure to give the include file a file name extension differing from that of other
|
|
source files, to avoid Sphinx finding it as a standalone document.)
|
|
|
|
Sphinx defines some default substitutions, see :ref:`default-substitutions`.
|
|
|
|
|
|
Comments
|
|
--------
|
|
|
|
Every explicit markup block which isn't a valid markup construct (like the
|
|
footnotes above) is regarded as a comment (:duref:`ref <comments>`). For
|
|
example::
|
|
|
|
.. This is a comment.
|
|
|
|
You can indent text after a comment start to form multiline comments::
|
|
|
|
..
|
|
This whole indented block
|
|
is a comment.
|
|
|
|
Still in the comment.
|
|
|
|
|
|
Source encoding
|
|
---------------
|
|
|
|
Since the easiest way to include special characters like em dashes or copyright
|
|
signs in reST is to directly write them as Unicode characters, one has to
|
|
specify an encoding. Sphinx assumes source files to be encoded in UTF-8 by
|
|
default; you can change this with the :confval:`source_encoding` config value.
|
|
|
|
|
|
Gotchas
|
|
-------
|
|
|
|
There are some problems one commonly runs into while authoring reST documents:
|
|
|
|
* **Separation of inline markup:** As said above, inline markup spans must be
|
|
separated from the surrounding text by non-word characters, you have to use a
|
|
backslash-escaped space to get around that. See `the reference
|
|
<http://docutils.sf.net/docs/ref/rst/restructuredtext.html#inline-markup>`_
|
|
for the details.
|
|
|
|
* **No nested inline markup:** Something like ``*see :func:`foo`*`` is not
|
|
possible.
|
|
|
|
|
|
.. rubric:: Footnotes
|
|
|
|
.. [1] When the default domain contains a :rst:dir:`class` directive, this directive
|
|
will be shadowed. Therefore, Sphinx re-exports it as :rst:dir:`rst-class`.
