This document describes the directives implemented in the reference |
|
|
reStructuredText parser. |
|
|
|
|
|
Directives have the following syntax:: |
|
|
|
|
|
+-------+-------------------------------+ |
|
|
| ".. " | directive type "::" directive | |
|
|
+-------+ block | |
|
|
| | |
|
|
+-------------------------------+ |
|
|
|
|
|
Directives begin with an explicit markup start (two periods and a |
|
|
space), followed by the directive type and two colons (collectively, |
|
|
the "directive marker"). The directive block begins immediately after |
|
|
the directive marker, and includes all subsequent indented lines. The |
|
|
directive block is divided into arguments, options (a field list), and |
|
|
content (in that order), any of which may appear. See the Directives_ |
|
|
section in the `reStructuredText Markup Specification`_ for syntax |
|
|
details. |
|
|
|
|
|
Descriptions below list "doctree elements" (document tree element |
|
|
names; XML DTD generic identifiers) corresponding to individual |
|
|
directives. For details on the hierarchy of elements, please see `The |
|
|
Docutils Document Tree`_ and the `Docutils Generic DTD`_ XML document |
|
|
type definition. For directive implementation details, see `Creating |
|

|
|
|
|
|
.. From Webster's Revised Unabridged Dictionary (1913) [web1913]: |
|
|
Admonition |
|
|
Gentle or friendly reproof; counseling against a fault or |
|
|
error; expression of authoritative advice; friendly caution |
|
|
or warning. |
|
|
|
|
|
Syn: {Admonition}, {Reprehension}, {Reproof}. |
|
|
|
|
|
Usage: Admonition is prospective, and relates to moral delinquencies; |
|
|
its object is to prevent further transgression. |

Specific Admonitions |
|
|
==================== |
|
|
|
|
|
:Directive Types: "attention", "caution", "danger", "error", "hint", |
|
|
"important", "note", "tip", "warning", "admonition" |
|
|
:Doctree Elements: attention, caution, danger, error, hint, important, |
|
|
note, tip, warning, admonition_, title |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: `:class:`_, `:name:`_ |
|
|
:Directive Content: Interpreted as body elements. |
|
|
|
|
|
Admonitions are specially marked "topics" that can appear anywhere an |
|
|
ordinary body element can. They contain arbitrary body elements. |
|
|
Typically, an admonition is rendered as an offset block in a document, |
|
|
sometimes outlined or shaded, with a title matching the admonition |
|
|
type. For example:: |
|
|
|
|
|
.. DANGER:: |
|
|
Beware killer rabbits! |
|
|
|
|
|
This directive might be rendered something like this:: |
|
|
|
|
|
+------------------------+ |
|
|
| !DANGER! | |
|
|
| | |
|
|
| Beware killer rabbits! | |
|
|
+------------------------+ |
|
|
|
|
|
The following admonition directives have been implemented: |
|
|
|
|
|
- attention |
|
|
- caution |
|
|
- danger |
|
|
- error |
|
|
- hint |
|
|
- important |
|
|
- note |
|
|
- tip |
|
|
- warning |
|
|
|
|
|
Any text immediately following the directive indicator (on the same |
|
|
line and/or indented on following lines) is interpreted as a directive |
|
|
block and is parsed for normal body elements. For example, the |
|
|
following "note" admonition directive contains one paragraph and a |
|
|
bullet list consisting of two list items:: |
|
|
|
|
|
.. note:: This is a note admonition. |
|
|
This is the second line of the first paragraph. |
|
|
|
|
|
- The note contains all indented body elements |
|
|
following. |
|
|
- It includes this bullet list. |

Generic Admonition |
|
|
================== |
|
|
|
|
|
:Directive Type: "admonition" |
|
|
:Doctree Elements: admonition_, title |
|
|
:Directive Arguments: One, required (admonition title) |
|
|
:Directive Options: Possible, see below. |
|
|
:Directive Content: Interpreted as body elements. |
|
|
|
|
|
This is a generic, titled admonition. The title may be anything the |
|
|
author desires. |
|
|
|
|
|
The author-supplied title is also used as a `"classes"`_ attribute value |
|
|
after being converted into a valid identifier form (down-cased; |
|
|
non-alphanumeric characters converted to single hyphens; "admonition-" |
|
|
prefixed). For example, this admonition:: |
|
|
|
|
|
.. admonition:: And, by the way... |
|
|
|
|
|
You can make up your own admonition too. |
|
|
|
|
|
becomes the following document tree (pseudo-XML):: |
|
|
|
|
|
<document source="test data"> |
|
|
<admonition classes="admonition-and-by-the-way"> |
|
|
<title> |
|
|
And, by the way... |
|
|
<paragraph> |
|
|
You can make up your own admonition too. |
|
|
|
|
|
The `common options`_ are recognized: |
|
|
|
|
|
``class`` : text |
|
|
Overrides the computed `"classes"`_ attribute value. |
|
|
|
|
|
``name`` : text |
|
|
Add `text` to the `"names"`_ attribute of the admonition element. |
|

Images |
|
|

|
|
|
|
|
There are two image directives: "image" and "figure". |
|
|
|
|
|
|
|
|
Image |
|
|
===== |
|
|
|
|
|
:Directive Type: "image" |
|
|
:Doctree Element: image_ |
|
|
:Directive Arguments: One, required (image URI). |
|
|
:Directive Options: Possible. |
|
|
:Directive Content: None. |
|
|
|
|
|
An "image" is a simple picture:: |
|
|
|
|
|
.. image:: picture.png |
|
|
|
|
|
Inline images can be defined with an "image" directive in a `substitution |
|
|
definition`_ |
|
|
|
|
|
The URI for the image source file is specified in the directive |
|
|
argument. As with hyperlink targets, the image URI may begin on the |
|
|
same line as the explicit markup start and target name, or it may |
|
|
begin in an indented text block immediately following, with no |
|
|
intervening blank lines. If there are multiple lines in the link |
|
|
block, they are stripped of leading and trailing whitespace and joined |
|
|
together. |
|
|
|
|
|
Optionally, the image link block may contain a flat field list, the |
|
|
_`image options`. For example:: |
|
|
|
|
|
.. image:: picture.jpeg |
|
|
:height: 100px |
|
|
:width: 200 px |
|
|
:scale: 50 % |
|
|
:alt: alternate text |
|
|
:align: right |
|
|
|
|
|
The following options are recognized: |
|
|
|
|
|
``alt`` : text |
|
|
Alternate text: a short description of the image, displayed by |
|
|
applications that cannot display images, or spoken by applications |
|
|
for visually impaired users. |
|
|
|
|
|
``height`` : `length`_ |
|
|
The desired height of the image. |
|
|
Used to reserve space or scale the image vertically. When the "scale" |
|
|
option is also specified, they are combined. For example, a height of |
|
|
200px and a scale of 50 is equivalent to a height of 100px with no scale. |
|
|
|
|
|
``width`` : `length`_ or `percentage`_ of the current line width |
|
|
The width of the image. |
|
|
Used to reserve space or scale the image horizontally. As with "height" |
|
|
above, when the "scale" option is also specified, they are combined. |
|
|
|
|
|
.. _length: restructuredtext.html#length-units |
|
|
.. _percentage: restructuredtext.html#percentage-units |
|
|
|
|
|
``scale`` : integer percentage (the "%" symbol is optional) |
|
|
The uniform scaling factor of the image. The default is "100 %", i.e. |
|
|
no scaling. |
|
|
|
|
|
If no "height" or "width" options are specified, the `Python Imaging |
|
|
Library`_ (PIL) may be used to determine them, if it is installed and |
|
|
the image file is available. |
|
|
|
|
|
``align`` : "top", "middle", "bottom", "left", "center", or "right" |
|
|
The alignment of the image, equivalent to the HTML ``<img>`` tag's |
|
|
deprecated "align" attribute or the corresponding "vertical-align" and |
|
|
"text-align" CSS properties. |
|
|
The values "top", "middle", and "bottom" |
|
|
control an image's vertical alignment (relative to the text |
|
|
baseline); they are only useful for inline images (substitutions). |
|
|
The values "left", "center", and "right" control an image's |
|
|
horizontal alignment, allowing the image to float and have the |
|
|
text flow around it. The specific behavior depends upon the |
|
|
browser or rendering software used. |
|
|
|
|
|
``target`` : text (URI or reference name) |
|
|
Makes the image into a hyperlink reference ("clickable"). The |
|
|
option argument may be a URI (relative or absolute), or a |
|
|
`reference name`_ with underscore suffix (e.g. ```a name`_``). |
|
|
|
|
|
and the common options `:class:`_ and `:name:`_. |
|
|
|
|
|
.. _substitution definition: restructuredtext.html#substitution-definitions |

|
|
|
|
|
|
Figure |
|
|
====== |
|
|
|
|
|
:Directive Type: "figure" |
|
|
:Doctree Elements: figure_, image_, caption_, legend_ |
|
|
:Directive Arguments: One, required (image URI). |
|
|
:Directive Options: Possible. |
|
|
:Directive Content: Interpreted as the figure caption and an optional |
|
|
legend. |
|
|
|
|
|
A "figure" consists of image_ data (including `image options`_), an optional |
|
|
caption (a single paragraph), and an optional legend (arbitrary body |
|
|
elements). For page-based output media, figures might float to a different |
|
|
position if this helps the page layout. |
|
|
:: |
|
|
|
|
|
.. figure:: picture.png |
|
|
:scale: 50 % |
|
|
:alt: map to buried treasure |
|
|
|
|
|
This is the caption of the figure (a simple paragraph). |
|
|
|
|
|
The legend consists of all elements after the caption. In this |
|
|
case, the legend consists of this paragraph and the following |
|
|
table: |
|
|
|
|
|
+-----------------------+-----------------------+ |
|
|
| Symbol | Meaning | |
|
|
+=======================+=======================+ |
|
|
| .. image:: tent.png | Campground | |
|
|
+-----------------------+-----------------------+ |
|
|
| .. image:: waves.png | Lake | |
|
|
+-----------------------+-----------------------+ |
|
|
| .. image:: peak.png | Mountain | |
|
|
+-----------------------+-----------------------+ |
|
|
|
|
|
There must be blank lines before the caption paragraph and before the |
|
|
legend. To specify a legend without a caption, use an empty comment |
|
|
("..") in place of the caption. |
|
|
|
|
|
The "figure" directive supports all of the options of the "image" |
|
|
directive (see `image options`_ above). These options (except |
|
|
"align") are passed on to the contained image. |
|
|
|
|
|
``align`` : "left", "center", or "right" |
|
|
The horizontal alignment of the figure, allowing the image to |
|
|
float and have the text flow around it. The specific behavior |
|
|
depends upon the browser or rendering software used. |
|
|
|
|
|
In addition, the following options are recognized: |
|
|
|
|
|
``figwidth`` : "image", length_, or percentage_ of current line width |
|
|
The width of the figure. |
|
|
Limits the horizontal space used by the figure. |
|
|
A special value of "image" is allowed, in which case the |
|
|
included image's actual width is used (requires the `Python Imaging |
|
|
Library`_). If the image file is not found or the required software is |
|
|
unavailable, this option is ignored. |
|
|
|
|
|
Sets the "width" attribute of the "figure" doctree element. |
|
|
|
|
|
This option does not scale the included image; use the "width" |
|
|
`image`_ option for that. :: |
|
|
|
|
|
+---------------------------+ |
|
|
| figure | |
|
|
| | |
|
|
|<------ figwidth --------->| |

|
| | | | |
|
|
| |<--- width --------->| | |
|
|
| +---------------------+ | |
|
|
| | |
|
|
|The figure's caption should| |
|
|
|wrap at this width. | |
|
|
+---------------------------+ |
|
|
|
|
|
``figclass`` : text |
|
|
Set a `"classes"`_ attribute value on the figure element. See the |
|
|
class_ directive below. |

Body Elements |

|
|
|
|
|
Topic |
|
|
===== |
|
|
|
|
|
:Directive Type: "topic" |
|
|
:Doctree Element: topic_ |
|
|
:Directive Arguments: 1, required (topic title). |
|
|
:Directive Options: `:class:`_, `:name:`_ |
|
|
:Directive Content: Interpreted as the topic body. |
|
|
|
|
|
A topic is like a block quote with a title, or a self-contained |
|
|
section with no subsections. Use the "topic" directive to indicate a |
|
|
self-contained idea that is separate from the flow of the document. |
|
|
Topics may occur anywhere a section or transition may occur. Body |
|
|
elements and topics may not contain nested topics. |
|
|
|
|
|
The directive's sole argument is interpreted as the topic title; the |
|
|
next line must be blank. All subsequent lines make up the topic body, |
|
|
interpreted as body elements. For example:: |
|
|
|
|
|
.. topic:: Topic Title |
|
|
|
|
|
Subsequent indented lines comprise |
|
|
the body of the topic, and are |
|
|
interpreted as body elements. |
|
|
|
|
|
|
|
|
Sidebar |
|
|
======= |
|
|
|
|
|
:Directive Type: "sidebar" |
|
|
:Doctree Element: sidebar_ |
|
|
:Directive Arguments: One, required (sidebar title). |
|
|
:Directive Options: Possible (see below). |
|
|
:Directive Content: Interpreted as the sidebar body. |
|
|
|
|
|
Sidebars are like miniature, parallel documents that occur inside |
|
|
other documents, providing related or reference material. A sidebar |
|
|
is typically offset by a border and "floats" to the side of the page; |
|
|
the document's main text may flow around it. Sidebars can also be |
|
|
likened to super-footnotes; their content is outside of the flow of |
|
|
the document's main text. |
|
|
|
|
|
Sidebars may occur anywhere a section or transition may occur. Body |
|
|
elements (including sidebars) may not contain nested sidebars. |
|
|
|
|
|
The directive's sole argument is interpreted as the sidebar title, |
|
|
which may be followed by a subtitle option (see below); the next line |
|
|
must be blank. All subsequent lines make up the sidebar body, |
|
|
interpreted as body elements. For example:: |
|
|
|
|
|
.. sidebar:: Sidebar Title |
|
|
:subtitle: Optional Sidebar Subtitle |
|
|
|
|
|
Subsequent indented lines comprise |
|
|
the body of the sidebar, and are |
|
|
interpreted as body elements. |
|
|
|
|
|
The following options are recognized: |
|
|
|
|
|
``subtitle`` : text |
|
|
The sidebar's subtitle. |
|
|
|
|
|
and the common options `:class:`_ and `:name:`_. |
|
|
|
|
|
|
|
|
Line Block |
|
|
========== |
|
|
|
|
|
.. admonition:: Deprecated |
|
|
|
|
|
The "line-block" directive is deprecated. Use the `line block |
|
|
syntax`_ instead. |
|
|
|
|
|
.. _line block syntax: restructuredtext.html#line-blocks |
|
|
|
|
|
:Directive Type: "line-block" |
|
|
:Doctree Element: line_block_ |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: `:class:`_, `:name:`_ |
|
|
:Directive Content: Becomes the body of the line block. |
|
|
|
|
|
The "line-block" directive constructs an element where line breaks and |
|
|
initial indentation is significant and inline markup is supported. It |
|
|
is equivalent to a `parsed literal block`_ with different rendering: |
|
|
typically in an ordinary serif typeface instead of a |
|
|
typewriter/monospaced face, and not automatically indented. (Have the |
|
|
line-block directive begin a block quote to get an indented line |
|
|
block.) Line blocks are useful for address blocks and verse (poetry, |
|
|
song lyrics), where the structure of lines is significant. For |
|
|
example, here's a classic:: |
|
|
|
|
|
"To Ma Own Beloved Lassie: A Poem on her 17th Birthday", by |
|
|
Ewan McTeagle (for Lassie O'Shea): |
|
|
|
|
|
.. line-block:: |
|
|
|
|
|
Lend us a couple of bob till Thursday. |
|
|
I'm absolutely skint. |
|
|
But I'm expecting a postal order and I can pay you back |
|
|
as soon as it comes. |
|
|
Love, Ewan. |

.. _parsed-literal: |
|
|
|
|
|
Parsed Literal Block |
|
|
==================== |
|
|
|
|
|
:Directive Type: "parsed-literal" |
|
|
:Doctree Element: literal_block_ |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: `:class:`_, `:name:`_ |
|
|
:Directive Content: Becomes the body of the literal block. |
|
|
|
|
|
Unlike an ordinary literal block, the "parsed-literal" directive |
|
|
constructs a literal block where the text is parsed for inline markup. |
|
|
It is equivalent to a `line block`_ with different rendering: |
|
|
typically in a typewriter/monospaced typeface, like an ordinary |
|
|
literal block. Parsed literal blocks are useful for adding hyperlinks |
|
|
to code examples. |
|
|
|
|
|
However, care must be taken with the text, because inline markup is |
|
|
recognized and there is no protection from parsing. Backslash-escapes |
|
|
may be necessary to prevent unintended parsing. And because the |
|
|
markup characters are removed by the parser, care must also be taken |
|
|
with vertical alignment. Parsed "ASCII art" is tricky, and extra |
|
|
whitespace may be necessary. |
|
|
|
|
|
For example, all the element names in this content model are links:: |
|
|
|
|
|
.. parsed-literal:: |
|
|
|
|
|
( (title_, subtitle_?)?, |
|
|
decoration_?, |
|
|
(docinfo_, transition_?)?, |
|
|
`%structure.model;`_ ) |
|
|
|
|
|
Code |
|
|
==== |
|
|
|
|
|
:Directive Type: "code" |
|
|
:Doctree Element: literal_block_, `inline elements`_ |
|
|
:Directive Arguments: One, optional (formal language). |
|
|
:Directive Options: name, class, number-lines. |
|
|
:Directive Content: Becomes the body of the literal block. |
|
|
:Configuration Setting: syntax_highlight_. |
|
|
|
|
|
(New in Docutils 0.9) |
|
|
|
|
|
The "code" directive constructs a literal block. If the code language is |
|
|
specified, the content is parsed by the Pygments_ syntax highlighter and |
|
|
tokens are stored in nested `inline elements`_ with class arguments |
|
|
according to their syntactic category. The actual highlighting requires |
|
|
a style-sheet (e.g. one `generated by Pygments`__, see the |
|
|
`sandbox/stylesheets`__ for examples). |
|
|
|
|
|
The parsing can be turned off with the syntax_highlight_ configuration |
|
|
setting and command line option or by specifying the language as `:class:`_ |
|
|
option instead of directive argument. This also avoids warnings |
|
|
when Pygments_ is not installed or the language is not in the |
|
|
`supported languages and markup formats`_. |
|
|
|
|

|
:Configuration Setting: math_output_ |
|
|
|
|
|
(New in Docutils 0.8) |
|
|
|
|
|
The "math" directive inserts blocks with mathematical content |
|
|
(display formulas, equations) into the document. The input format is |
|
|
*LaTeX math syntax*\ [#math-syntax]_ with support for Unicode |
|
|
symbols, for example:: |
|
|
|
|
|
.. math:: |
|
|
|
|
|
α_t(i) = P(O_1, O_2, … O_t, q_t = S_i λ) |
|
|
|
|
|
Support is limited to a subset of *LaTeX math* by the conversion |
|
|
required for many output formats. For HTML, the `math_output`_ |
|
|
configuration setting (or the corresponding ``--math-output`` |
|
|
command line option) select between alternative output formats with |
|
|
different subsets of supported elements. If a writer does not |
|
|
support math typesetting at all, the content is inserted verbatim. |
|
|
|
|
|
.. [#math-syntax] The supported LaTeX commands include AMS extensions |
|
|
(see, e.g., the `Short Math Guide`_). |

|
|
|
|
|
-- Random House Webster's College Dictionary, 1991 |
|
|
|
|
|
The "rubric" directive inserts a "rubric" element into the document |
|
|
tree. A rubric is like an informal heading that doesn't correspond to |
|
|
the document's structure. |

:Directive Options: None. |
|
|
:Directive Content: Interpreted as the body of the block quote. |
|
|
|
|
|
An epigraph is an apposite (suitable, apt, or pertinent) short |
|
|
inscription, often a quotation or poem, at the beginning of a document |
|
|
or section. |
|
|
|
|
|
The "epigraph" directive produces an "epigraph"-class block quote. |
|
|
For example, this input:: |
|
|
|
|
|
.. epigraph:: |
|
|

:Directive Content: Interpreted as the body of the block quote. |
|
|
|
|
|
A pull-quote is a small selection of text "pulled out and quoted", |
|
|
typically in a larger typeface. Pull-quotes are used to attract |
|
|
attention, especially in long articles. |
|
|
|
|
|
The "pull-quote" directive produces a "pull-quote"-class block quote. |

Compound Paragraph |
|
|
================== |
|
|
|
|
|
:Directive Type: "compound" |
|
|
:Doctree Element: compound_ |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: `:class:`_, `:name:`_ |
|
|
:Directive Content: Interpreted as body elements. |
|
|
|
|
|
(New in Docutils 0.3.6) |
|
|
|
|
|
The "compound" directive is used to create a compound paragraph, which |
|
|
is a single logical paragraph containing multiple physical body |
|
|
elements such as simple paragraphs, literal blocks, tables, lists, |
|
|
etc., instead of directly containing text and inline elements. For |
|
|
example:: |
|
|
|
|
|
.. compound:: |
|
|
|
|
|
The 'rm' command is very dangerous. If you are logged |
|
|
in as root and enter :: |
|
|
|
|
|
cd / |
|
|
rm -rf * |
|
|
|
|
|
you will erase the entire contents of your file system. |
|
|
|
|
|
In the example above, a literal block is "embedded" within a sentence |
|
|
that begins in one physical paragraph and ends in another. |
|
|
|
|
|
.. note:: |
|
|
|
|
|
The "compound" directive is *not* a generic block-level container |
|
|
like HTML's ``<div>`` element. Do not use it only to group a |
|
|
sequence of elements, or you may get unexpected results. |
|
|
|
|
|
If you need a generic block-level container, please use the |
|
|
container_ directive, described below. |
|
|
|
|
|
Compound paragraphs are typically rendered as multiple distinct text |
|
|
blocks, with the possibility of variations to emphasize their logical |
|
|
unity: |
|
|
|
|
|
* If paragraphs are rendered with a first-line indent, only the first |
|
|
physical paragraph of a compound paragraph should have that indent |
|
|
-- second and further physical paragraphs should omit the indents; |
|
|
* vertical spacing between physical elements may be reduced; |
|
|
* and so on. |
|
|
|
|
|
|
|
|
Container |
|
|
========= |
|
|
|
|
|
:Directive Type: "container" |
|
|
:Doctree Element: container_ |
|
|
:Directive Arguments: One or more, optional (class names). |
|
|
:Directive Options: `:name:`_ |
|
|
:Directive Content: Interpreted as body elements. |
|
|
|
|
|
(New in Docutils 0.3.10) |
|
|
|
|
|
The "container" directive surrounds its contents (arbitrary body |
|
|
elements) with a generic block-level "container" element. Combined |
|
|
with the optional "classes_" attribute argument(s), this is an |
|
|
extension mechanism for users & applications. For example:: |
|
|
|
|
|
.. container:: custom |
|
|
|
|
|
This paragraph might be rendered in a custom way. |
|
|
|
|
|
Parsing the above results in the following pseudo-XML:: |
|
|
|
|
|
<container classes="custom"> |
|
|
<paragraph> |
|
|
This paragraph might be rendered in a custom way. |
|
|
|
|
|
The "container" directive is the equivalent of HTML's ``<div>`` |
|
|
element. It may be used to group a sequence of elements for user- or |
|
|
application-specific purposes. |

|
|
|
|

Formal tables need more structure than the reStructuredText syntax |
|
|
supplies. Tables may be given titles with the table_ directive. |
|
|
Sometimes reStructuredText tables are inconvenient to write, or table |
|
|
data in a standard format is readily available. The csv-table_ |
|
|
directive supports CSV data. |

(New in Docutils 0.13) |
|
|
|
|
|
``widths`` : "auto", "grid" or a list of integers |

A comma- or space-separated list of column widths. |
|
|
The default is the width of the input columns (in characters). |
|
|
|
|
|
The special values "auto" or "grid" may be used by writers to decide |

|
|
|
.. WARNING:: |
|
|
|
|
|
The "csv-table" directive's ":file:" and ":url:" options represent |

"file_insertion_enabled_" runtime setting. |
|
|
|
|
|
(New in Docutils 0.3.4) |
|
|
|
|
|
The "csv-table" directive is used to create a table from CSV |
|
|
(comma-separated values) data. CSV is a common data format generated |
|
|
by spreadsheet applications and commercial databases. The data may be |
|
|
internal (an integral part of the document) or external (a separate |
|
|
file). |
|
|
|
|
|
Example:: |
|
|
|
|
|
.. csv-table:: Frozen Delights! |
|
|
:header: "Treat", "Quantity", "Description" |
|
|
:widths: 15, 10, 30 |
|
|
|
|
|
"Albatross", 2.99, "On a stick!" |
|
|
"Crunchy Frog", 1.49, "If we took the bones out, it wouldn't be |
|
|
crunchy, now would it?" |
|
|
"Gannet Ripple", 1.99, "On a stick!" |
|
|
|
|
|
Block markup and inline markup within cells is supported. Line ends |
|
|
are recognized within cells. |
|
|
|
|
|
Working limitations: |
|
|
|
|
|
* There is no support for checking that the number of columns in each |
|
|
row is the same. However, this directive supports CSV generators |
|
|
that do not insert "empty" entries at the end of short rows, by |
|
|
automatically adding empty entries. |
|
|
|
|
|
.. Add "strict" option to verify input? |
|
|
|
|
|
.. [#whitespace-delim] Whitespace delimiters are supported only for external |
|
|
CSV files. |
|
|
|
|
|
.. [#ASCII-char] With Python 2, the valuess for the ``delimiter``, |
|
|
``quote``, and ``escape`` options must be ASCII characters. (The csv |
|
|
module does not support Unicode and all non-ASCII characters are |
|
|
encoded as multi-byte utf-8 string). This limitation does not exist |
|
|
under Python 3. |
|
|
|
|
|
The following options are recognized: |
|
|
|
|
|
``widths`` : integer [, integer...] or "auto" |
|
|
A comma- or space-separated list of relative column widths. The |
|
|
default is equal-width columns (100%/#columns). |
|
|
|
|
|
The special value "auto" may be used by writers to decide |
|
|
whether to delegate the determination of column widths to the backend |
|
|
(LaTeX, the HTML browser, ...). |
|
|
|
|
|
``header-rows`` : integer |

|
The number of rows of CSV data to use in the table header. |
|
|
Defaults to 0. |
|
|
|
|
|
``stub-columns`` : integer |
|
|
The number of table columns to use as stubs (row titles, on the |
|
|
left). Defaults to 0. |
|
|
|
|
|
``header`` : CSV data |
|
|
Supplemental data for the table header, added independently of and |
|
|
before any ``header-rows`` from the main CSV data. Must use the |
|
|
same CSV format as the main CSV data. |
|
|
|
|
|
``file`` : string (newlines removed) |
|
|
The local filesystem path to a CSV data file. |
|
|
|
|

|
|
An Internet URL reference to a CSV data file. |
|
|
|
|
|
``encoding`` : name of text encoding |
|
|
The text encoding of the external CSV data (file or URL). |
|
|
Defaults to the document's encoding (if specified). |

|
``delim`` : char | "tab" | "space" [#whitespace-delim]_ |
|
|
A one-character string\ [#ASCII-char]_ used to separate fields. |
|
|
Defaults to ``,`` (comma). May be specified as a Unicode code |
|
|
point; see the unicode_ directive for syntax details. |
|
|
|
|
|
``quote`` : char |
|
|
A one-character string\ [#ASCII-char]_ used to quote elements |

|
significant. The default is to ignore such whitespace. |
|
|
|
|
|
``escape`` : char |
|
|
A one-character\ [#ASCII-char]_ string used to escape the |
|
|
delimiter or quote characters. May be specified as a Unicode |
|
|
code point; see the unicode_ directive for syntax details. Used |
|
|
when the delimiter is used in an unquoted field, or when quote |
|
|
characters are used within a field. The default is to double-up |
|
|
the character, e.g. "He said, ""Hi!""" |
|
|
|
|
|
.. Add another possible value, "double", to explicitly indicate |
|

:Directive Arguments: One, optional: title. |
|
|
:Directive Options: Possible. |
|
|
:Directive Content: None. |
|
|
|
|
|
The "contents" directive generates a table of contents (TOC) in a |
|
|
topic_. Topics, and therefore tables of contents, may occur anywhere |
|
|
a section or transition may occur. Body elements and topics may not |
|
|
contain tables of contents. |
|
|
|
|
|
Here's the directive in its simplest form:: |
|
|
|
|
|
.. contents:: |
|
|
|
|
|
Language-dependent boilerplate text will be used for the title. The |
|
|
English default title text is "Contents". |
|
|
|
|
|
An explicit title may be specified:: |
|
|
|
|
|
.. contents:: Table of Contents |
|
|
|
|
|
The title may span lines, although it is not recommended:: |
|
|
|
|
|
.. contents:: Here's a very long Table of |
|
|
Contents title |
|
|
|
|
|
Options may be specified for the directive, using a field list:: |
|
|
|
|
|
.. contents:: Table of Contents |
|
|
:depth: 2 |
|
|
|
|
|
If the default title is to be used, the options field list may begin |

Automatic Section Numbering |

:Directive Type: "sectnum" or "section-numbering" (synonyms) |
|
|
:Doctree Elements: pending_, generated_ |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: Possible. |
|
|
:Directive Content: None. |
|
|
:Configuration Setting: sectnum_xform_ |
|
|
|
|
|
The "sectnum" (or "section-numbering") directive automatically numbers |
|
|
sections and subsections in a document (if not disabled by the |
|
|
``--no-section-numbering`` command line option or the `sectnum_xform`_ |
|
|
configuration setting). |
|
|
|
|
|
Section numbers are of the "multiple enumeration" form, where each |
|
|
level has a number, separated by periods. For example, the title of section |
|
|
1, subsection 2, subsubsection 3 would have "1.2.3" prefixed. |
|
|
|
|
|
The "sectnum" directive does its work in two passes: the initial parse |
|
|
and a transform. During the initial parse, a "pending" element is |
|
|
generated which acts as a placeholder, storing any options internally. |
|
|
At a later stage in the processing, the "pending" element triggers a |
|
|
transform, which adds section numbers to titles. Section numbers are |
|
|
enclosed in a "generated" element, and titles have their "auto" |
|
|
attribute set to "1". |
|
|
|
|
|
The following options are recognized: |
|
|
|
|
|
``depth`` : integer |
|
|
The number of section levels that are numbered by this directive. |
|
|
The default is unlimited depth. |
|
|
|
|
|
``prefix`` : string |
|
|
An arbitrary string that is prefixed to the automatically |
|
|
generated section numbers. It may be something like "3.2.", which |
|
|
will produce "3.2.1", "3.2.2", "3.2.2.1", and so on. Note that |
|
|
any separating punctuation (in the example, a period, ".") must be |
|
|
explicitly provided. The default is no prefix. |
|
|
|
|
|
``suffix`` : string |
|
|
An arbitrary string that is appended to the automatically |
|
|
generated section numbers. The default is no suffix. |
|
|
|
|
|
``start`` : integer |
|
|
The value that will be used for the first section number. |
|
|
Combined with ``prefix``, this may be used to force the right |
|
|
numbering for a document split over several source files. The |
|
|
default is 1. |

Document Header & Footer |
|
|
======================== |
|
|
|
|
|
:Directive Types: "header" and "footer" |
|
|
:Doctree Elements: decoration_, header, footer |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: None. |
|
|
:Directive Content: Interpreted as body elements. |
|
|
|
|
|
(New in Docutils 0.3.8) |
|
|
|
|
|
The "header" and "footer" directives create document decorations, |
|
|
useful for page navigation, notes, time/datestamp, etc. For example:: |
|
|
|
|
|
.. header:: This space for rent. |
|
|
|
|
|
This will add a paragraph to the document header, which will appear at |
|
|
the top of the generated web page or at the top of every printed page. |
|
|
|
|
|
These directives may be used multiple times, cumulatively. There is |
|
|
currently support for only one header and footer. |
|
|
|
|
|
.. note:: |
|
|
|
|
|
While it is possible to use the "header" and "footer" directives to |
|
|
create navigational elements for web pages, you should be aware |
|
|
that Docutils is meant to be used for *document* processing, and |
|
|
that a navigation bar is not typically part of a document. |
|
|
|
|
|
Thus, you may soon find Docutils' abilities to be insufficient for |
|
|
these purposes. At that time, you should consider using a |
|
|
documentation generator like Sphinx_ rather than the "header" and |
|
|
"footer" directives. |
|
|
|
|
|
.. _Sphinx: http://sphinx-doc.org/ |
|
|
|
|
|
In addition to the use of these directives to populate header and |
|
|
footer content, content may also be added automatically by the |
|
|
processing system. For example, if certain runtime settings are |
|
|
enabled, the document footer is populated with processing information |
|
|
such as a datestamp, a link to `the Docutils website`_, etc. |

|
|
|
|
|
The "target-notes" directive creates a footnote for each external |
|
|
target in the text, and corresponding footnote references after each |
|
|
reference. For every explicit target (of the form, ``.. _target name: |
|
|
URL``) in the text, a footnote will be generated containing the |
|
|
visible URL as content. |

|
|
|
|
|
:Directive Type: "meta" |
|
|
:Doctree Element: meta (non-standard) |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: None. |
|
|
:Directive Content: Must contain a flat field list. |
|
|
|
|
|
The "meta" directive is used to specify HTML metadata stored in HTML |
|
|
META tags. "Metadata" is data about data, in this case data about web |
|
|
pages. Metadata is used to describe and classify web pages in the |
|
|
World Wide Web, in a form that is easy for search engines to extract |
|
|
and collate. |
|
|
|
|
|
Within the directive block, a flat field list provides the syntax for |
|
|
metadata. The field name becomes the contents of the "name" attribute |
|
|
of the META tag, and the field body (interpreted as a single string |
|
|
without inline markup) becomes the contents of the "content" |
|
|
attribute. For example:: |
|
|
|
|
|
.. meta:: |
|
|
:description: The reStructuredText plaintext markup language |
|
|
:keywords: plaintext, markup language |
|
|
|
|
|
This would be converted to the following HTML:: |
|
|
|
|
|
<meta name="description" |
|
|
content="The reStructuredText plaintext markup language"> |
|
|
<meta name="keywords" content="plaintext, markup language"> |
|
|
|
|
|
Support for other META attributes ("http-equiv", "scheme", "lang", |
|
|
"dir") are provided through field arguments, which must be of the form |
|
|
"attr=value":: |
|
|
|
|
|
.. meta:: |
|
|
:description lang=en: An amusing story |
|
|
:description lang=fr: Une histoire amusante |
|
|
|
|
|
And their HTML equivalents:: |
|
|
|
|
|
<meta name="description" lang="en" content="An amusing story"> |
|
|
<meta name="description" lang="fr" content="Une histoire amusante"> |
|
|
|
|
|
Some META tags use an "http-equiv" attribute instead of the "name" |
|
|
attribute. To specify "http-equiv" META tags, simply omit the name:: |
|
|
|
|
|
.. meta:: |
|
|
:http-equiv=Content-Type: text/html; charset=ISO-8859-1 |
|
|
|
|
|
HTML equivalent:: |
|
|
|
|
|
<meta http-equiv="Content-Type" |
|

Directives for Substitution Definitions |
|
|
----------------------------------------- |
|
|
|
|
|
The directives in this section may only be used in substitution |
|
|
definitions. They may not be used directly, in standalone context. |
|
|
The `image`_ directive may be used both in substitution definitions |
|
|
and in the standalone context. |
|
|
|
|
|
|
|
|
.. _replace: |
|

|
Replacement Text |
|
|
================ |
|
|
|
|
|
:Directive Type: "replace" |
|
|
:Doctree Element: Text & `inline elements`_ |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: None. |
|
|
:Directive Content: A single paragraph; may contain inline markup. |
|
|
|
|
|
The "replace" directive is used to indicate replacement text for a |
|
|
substitution reference. It may be used within substitution |
|
|
definitions only. For example, this directive can be used to expand |
|
|
abbreviations:: |
|
|
|
|
|
.. |reST| replace:: reStructuredText |
|
|
|
|
|
Yes, |reST| is a long word, so I can't blame anyone for wanting to |
|
|
abbreviate it. |
|
|
|
|
|
As reStructuredText doesn't support nested inline markup, the only way |
|
|
to create a reference with styled text is to use substitutions with |
|
|
the "replace" directive:: |
|
|
|
|
|
I recommend you try |Python|_. |
|

Unicode Character Codes |
|
|
======================= |
|
|
|
|
|
:Directive Type: "unicode" |
|
|
:Doctree Element: Text |
|
|
:Directive Arguments: One or more, required (Unicode character codes, |
|
|
optional text, and comments). |
|
|
:Directive Options: Possible. |
|
|
:Directive Content: None. |
|
|
|
|
|
The "unicode" directive converts Unicode character codes (numerical |
|
|
values) to characters, and may be used in substitution definitions |
|
|
only. |
|
|
|
|
|
The arguments, separated by spaces, can be: |
|
|
|
|
|
* **character codes** as |
|
|
|
|
|
- decimal numbers or |
|
|
|
|
|
- hexadecimal numbers, prefixed by ``0x``, ``x``, ``\x``, ``U+``, |
|
|
``u``, or ``\u`` or as XML-style hexadecimal character entities, |
|
|
e.g. ``ᨫ`` |
|
|
|
|
|
* **text**, which is used as-is. |
|
|
|
|
|
Text following " .. " is a comment and is ignored. The spaces between |
|
|
the arguments are ignored and thus do not appear in the output. |
|
|
Hexadecimal codes are case-insensitive. |
|
|
|
|
|
For example, the following text:: |
|
|
|
|
|
Copyright |copy| 2003, |BogusMegaCorp (TM)| |---| |
|
|
all rights reserved. |
|
|
|
|
|
.. |copy| unicode:: 0xA9 .. copyright sign |
|
|
.. |BogusMegaCorp (TM)| unicode:: BogusMegaCorp U+2122 |
|
|
.. with trademark sign |
|
|
.. |---| unicode:: U+02014 .. em dash |
|
|
:trim: |
|
|
|
|
|
results in: |
|
|
|
|
|
Copyright |copy| 2003, |BogusMegaCorp (TM)| |---| |
|
|
all rights reserved. |
|
|
|
|
|
.. |copy| unicode:: 0xA9 .. copyright sign |
|
|
.. |BogusMegaCorp (TM)| unicode:: BogusMegaCorp U+2122 |
|
|
.. with trademark sign |
|
|
.. |---| unicode:: U+02014 .. em dash |
|
|
:trim: |
|
|
|
|
|
The following options are recognized: |
|
|
|
|
|
``ltrim`` : flag |
|
|
Whitespace to the left of the substitution reference is removed. |
|
|
|
|
|
``rtrim`` : flag |
|
|
Whitespace to the right of the substitution reference is removed. |
|
|
|
|
|
``trim`` : flag |
|
|
Equivalent to ``ltrim`` plus ``rtrim``; whitespace on both sides |
|
|
of the substitution reference is removed. |

|
:Directive Arguments: One, optional (date format). |

:Directive Options: None. |
|
|
:Directive Content: None. |
|
|
|
|
|
The "date" directive generates the current local date and inserts it |
|
|
into the document as text. This directive may be used in substitution |
|
|
definitions only. |
|
|
|
|
|
The optional directive content is interpreted as the desired date |
|
|
format, using the same codes as Python's time.strftime function. The |
|
|
default format is "%Y-%m-%d" (ISO 8601 date), but time fields can also |
|
|
be used. Examples:: |
|
|
|
|
|
.. |date| date:: |
|
|
.. |time| date:: %H:%M |
|
|
|
|
|
Today's date is |date|. |
|
|
|
|
|
This document was generated on |date| at |time|. |

:Directive Type: "include" |
|
|
:Doctree Elements: Depend on data being included |
|
|
(literal_block_ with ``code`` or ``literal`` option). |
|
|
:Directive Arguments: One, required (path to the file to include). |
|
|
:Directive Options: Possible. |
|
|
:Directive Content: None. |
|
|
:Configuration Setting: file_insertion_enabled_ |
|
|
|
|
|
.. WARNING:: |
|
|
|
|
|
The "include" directive represents a potential security hole. It |
|
|
can be disabled with the "file_insertion_enabled_" runtime setting. |
|
|
|
|
|
.. _file_insertion_enabled: ../../user/config.html#file-insertion-enabled |
|
|
|
|
|
The "include" directive reads a text file. The directive argument is |
|
|
the path to the file to be included, relative to the document |
|
|
containing the directive. Unless the options ``literal`` or ``code`` |
|
|
are given, the file is parsed in the current document's context at the |
|
|
point of the directive. For example:: |
|
|
|
|
|
This first example will be parsed at the document level, and can |
|
|
thus contain any construct, including section headers. |
|
|
|
|
|
.. include:: inclusion.txt |
|
|
|
|
|
Back in the main document. |
|
|
|
|
|
This second example will be parsed in a block quote context. |
|
|
Therefore it may only contain body elements. It may not |
|
|
contain section headers. |
|
|
|
|
|
.. include:: inclusion.txt |
|
|
|
|
|
If an included document fragment contains section structure, the title |
|
|
adornments must match those of the master document. |
|
|
|
|
|
Standard data files intended for inclusion in reStructuredText |
|
|
documents are distributed with the Docutils source code, located in |
|
|
the "docutils" package in the ``docutils/parsers/rst/include`` |
|
|
directory. To access these files, use the special syntax for standard |
|
|
"include" data files, angle brackets around the file name:: |
|
|
|
|
|
.. include:: <isonum.txt> |
|
|
|
|
|
The current set of standard "include" data files consists of sets of |
|
|
substitution definitions. See `reStructuredText Standard Definition |
|
|
Files`__ for details. |

``start-line`` : integer |
|
|
Only the content starting from this line will be included. |
|
|
(As usual in Python, the first line has index 0 and negative values |
|
|
count from the end.) |
|
|
|
|
|
``end-line`` : integer |
|
|
Only the content up to (but excluding) this line will be included. |
|
|
|
|
|
``start-after`` : text to find in the external data file |
|
|
Only the content after the first occurrence of the specified text |
|
|
will be included. |
|
|
|
|
|
``end-before`` : text to find in the external data file |
|
|
Only the content before the first occurrence of the specified text |
|
|
(but after any ``after`` text) will be included. |
|
|
|
|
|
``literal`` : flag (empty) |
|
|
The entire included text is inserted into the document as a single |
|
|
literal block. |
|
|
|
|
|
``code`` : formal language (optional) |
|
|
The argument and the content of the included file are passed to |
|
|
the code_ directive (useful for program listings). |
|
|
(New in Docutils 0.9) |
|
|
|
|
|
``number-lines`` : [start line number] |
|
|
Precede every code line with a line number. |
|
|
The optional argument is the number of the first line (defaut 1). |
|
|
Works only with ``code`` or ``literal``. |
|
|
(New in Docutils 0.9) |
|
|
|
|
|
``encoding`` : name of text encoding |
|
|
The text encoding of the external data file. Defaults to the |
|
|
document's input_encoding_. |
|
|
|
|
|
.. _input_encoding: ../../user/config.html#input-encoding |
|
|
|
|
|
``tab-width`` : integer |
|
|
Number of spaces for hard tab expansion. |
|
|
A negative value prevents expansion of hard tabs. Defaults to the |
|
|
tab_width_ configuration setting. |
|
|
|
|
|
.. _tab_width: ../../user/config.html#tab-width |
|
|
|
|
|
|
|
|
With ``code`` or ``literal`` the common options `:class:`_ and |
|
|
`:name:`_ are recognized as well. |
|
|
|
|
|
Combining ``start/end-line`` and ``start-after/end-before`` is possible. The |
|
|
text markers will be searched in the specified lines (further limiting the |
|

documents to specific output formats and makes them less portable. |

|
|
|
|
If you often need to use the "raw" directive or a "raw"-derived |
|
|
interpreted text role, that is a sign either of overuse/abuse or |
|
|
that functionality may be missing from reStructuredText. Please |
|
|
describe your situation in a message to the Docutils-users_ mailing |
|
|
list. |

|
|
The "raw" directive indicates non-reStructuredText data that is to be |
|
|
passed untouched to the Writer. The names of the output formats are |
|
|
given in the directive arguments. The interpretation of the raw data |
|
|
is up to the Writer. A Writer may ignore any raw output not matching |
|
|
its format. |
|
|
|
|
|
For example, the following input would be passed untouched by an HTML |
|
|
Writer:: |
|
|
|
|
|
.. raw:: html |
|
|
|
|
|
<hr width=50 size=10> |
|
|
|
|
|
A LaTeX Writer could insert the following raw content into its |
|
|
output stream:: |
|
|
|
|
|
.. raw:: latex |
|
|
|
|
|
\setlength{\parindent}{0pt} |
|
|
|
|
|
Raw data can also be read from an external file, specified in a |
|
|
directive option. In this case, the content block must be empty. For |
|
|
example:: |
|
|
|
|
|
.. raw:: html |
|
|
:file: inclusion.html |
|
|
|
|
|
Inline equivalents of the "raw" directive can be defined via |
|
|
`custom interpreted text roles`_ derived from the `"raw" role`_. |
|
|
|
|
|
The following options are recognized: |
|
|
|
|
|
``file`` : string (newlines removed) |
|
|
The local filesystem path of a raw data file to be included. |
|
|
|
|
|
``url`` : string (whitespace removed) |
|
|
An Internet URL reference to a raw data file to be included. |
|
|
|
|
|
``encoding`` : name of text encoding |
|
|
The text encoding of the external raw data (file or URL). |
|
|
Defaults to the document's encoding (if specified). |

|
|
:Directive Arguments: One or more, required (class names / attribute |
|
|
values). |
|
|
:Directive Options: None. |
|
|
:Directive Content: Optional. If present, it is interpreted as body |
|
|
elements. |
|
|
|
|
|
The "class" directive sets the `"classes"`_ attribute value on its content |
|
|
or on the first immediately following [#]_ non-comment element [#]_. For |
|
|
details of the "classes" attribute, see the `classes entry in The Docutils |
|
|
Document Tree`__. |
|
|
|
|
|
The directive argument consists of one or more space-separated class |
|
|
names. The names are transformed to conform to the regular expression |
|
|
``[a-z](-?[a-z0-9]+)*`` by converting |
|
|
|
|
|
* alphabetic characters to lowercase, |
|
|
* accented characters to the base character, |
|
|
* non-alphanumeric characters to hyphens, |
|
|
* consecutive hyphens into one hyphen. |
|
|
|
|
|
For example "Rot-Gelb.Blau Grün:+2008" becomes "rot-gelb-blau grun-2008". |

|
|
the note but the next paragraph. |
|
|
|
|
|
.. class:: special |
|
|
|
|
|
This is a paragraph with class value "special". |
|
|
|
|
|
This allows the "classification" of individual list items (except the |
|
|
first, as a preceding class directive applies to the list as a whole):: |
|
|
|
|
|
* bullet list |
|

.. class:: classy item |

|
|
|
.. class:: highlights |
|
|
.. |
|
|
|
|
|
Block quote text. |
|
|
|
|
|
Without the empty comment, the indented text would be interpreted as the |
|
|
"class" directive's content, and the classes would be applied to each |
|
|
element (paragraph, in this case) individually, instead of to the block |
|
|
quote as a whole. |

|
|
|
|
.. _rationale: |
|
|
|
|
|
.. topic:: Rationale for "classes" Attribute Value Conversion |
|
|
|
|
|
|
|
|
Docutils identifiers are converted to conform to the regular |
|
|
expression ``[a-z](-?[a-z0-9]+)*``. For HTML + CSS compatibility, |
|
|
identifiers (the "classes" and "id" attributes) should have no |
|
|
underscores, colons, or periods. Hyphens may be used. |
|
|
|
|
|
- The `HTML 4.01 spec`_ defines identifiers based on SGML tokens: |
|
|
|
|
|
ID and NAME tokens must begin with a letter ([A-Za-z]) and |
|
|
may be followed by any number of letters, digits ([0-9]), |
|
|
hyphens ("-"), underscores ("_"), colons (":"), and periods |
|
|
("."). |
|
|
|
|
|
- The `CSS1 spec`_ defines identifiers based on the "name" token |
|
|
("flex" tokenizer notation below; "latin1" and "escape" 8-bit |
|
|
characters have been replaced with XML entities):: |
|
|
|
|
|
unicode \\[0-9a-f]{1,4} |
|
|
latin1 [¡-ÿ] |
|
|
escape {unicode}|\\[ -~¡-ÿ] |
|
|
nmchar [-A-Za-z0-9]|{latin1}|{escape} |
|
|
name {nmchar}+ |
|
|
|
|
|
The CSS rule does not include underscores ("_"), colons (":"), or |
|
|
periods ("."), therefore "classes" and "id" attributes should not |
|
|
contain these characters. Combined with HTML's requirements (the |
|
|
first character must be a letter; no "unicode", "latin1", or |
|
|
"escape" characters), this results in the regular expression |
|
|
``[A-Za-z][-A-Za-z0-9]*``. Docutils adds a normalisation by |
|
|
downcasing and merge of consecutive hyphens. |

Custom Interpreted Text Roles |
|
|
============================= |
|
|
|
|
|
:Directive Type: "role" |
|
|
:Doctree Element: None; affects subsequent parsing. |
|
|
:Directive Arguments: Two; one required (new role name), one optional |
|
|
(base role name, in parentheses). |
|
|
:Directive Options: Possible (depends on base role). |
|
|
:Directive Content: depends on base role. |
|
|
|
|
|
(New in Docutils 0.3.2) |
|
|
|
|
|
The "role" directive dynamically creates a custom interpreted text |
|
|
role and registers it with the parser. This means that after |
|
|
declaring a role like this:: |
|
|
|
|
|
.. role:: custom |
|
|
|
|
|
the document may use the new "custom" role:: |
|
|
|
|
|
An example of using :custom:`interpreted text` |
|
|
|
|
|
This will be parsed into the following document tree fragment:: |
|
|
|
|
|
<paragraph> |
|
|
An example of using |
|
|
<inline classes="custom"> |
|
|
interpreted text |
|
|
|
|
|
The role must be declared in a document before it can be used. |
|
|
|
|
|
The new role may be based on an existing role, specified as a second |
|
|
argument in parentheses (whitespace optional):: |
|
|
|
|
|
.. role:: custom(emphasis) |
|
|
|
|
|
:custom:`text` |
|
|
|
|
|
The parsed result is as follows:: |
|
|
|
|
|
<paragraph> |
|
|
<emphasis classes="custom"> |
|
|
text |
|
|
|
|
|
A special case is the `"raw" role`_: derived roles enable |
|
|
inline `raw data pass-through`_, e.g.:: |
|
|
|
|
|
.. role:: raw-role(raw) |
|
|
:format: html latex |
|
|
|
|
|
:raw-role:`raw text` |
|
|
|
|
|
If no base role is explicitly specified, a generic custom role is |
|
|
automatically used. Subsequent interpreted text will produce an |
|
|
"inline" element with a `"classes"`_ attribute, as in the first example |
|
|
above. |
|
|
|
|
|
With most roles, the ":class:" option can be used to set a "classes" |
|
|
attribute that is different from the role name. For example:: |
|
|
|
|
|
.. role:: custom |
|
|
:class: special |
|
|
|
|
|
:custom:`interpreted text` |
|
|
|
|
|
This is the parsed result:: |
|
|
|
|
|
<paragraph> |
|
|
<inline classes="special"> |
|
|
interpreted text |
|
|
|
|
|
.. _role class: |
|
|
|
|
|
The following option is recognized by the "role" directive for most |
|
|
base roles: |
|
|
|
|
|
``class`` : text |
|
|
Set the `"classes"`_ attribute value on the element produced |
|
|
(``inline``, or element associated with a base class) when the |
|
|
custom interpreted text role is used. If no directive options are |
|
|
specified, a "class" option with the directive argument (role |
|
|
name) as the value is implied. See the class_ directive above. |
|
|
|
|
|
Specific base roles may support other options and/or directive |
|
|
content. See the `reStructuredText Interpreted Text Roles`_ document |
|
|
for details. |

Setting the Default Interpreted Text Role |
|
|
========================================= |
|
|
|
|
|
:Directive Type: "default-role" |
|
|
:Doctree Element: None; affects subsequent parsing. |
|
|
:Directive Arguments: One, optional (new default role name). |
|
|
:Directive Options: None. |
|
|
:Directive Content: None. |
|
|
|
|
|
(New in Docutils 0.3.10) |
|
|
|
|
|
The "default-role" directive sets the default interpreted text role, |
|
|
the role that is used for interpreted text without an explicit role. |
|
|
For example, after setting the default role like this:: |
|
|
|
|
|
.. default-role:: subscript |
|
|
|
|
|
any subsequent use of implicit-role interpreted text in the document |
|
|
will use the "subscript" role:: |
|
|
|
|
|
An example of a `default` role. |
|
|
|
|
|
This will be parsed into the following document tree fragment:: |
|
|
|
|
|
<paragraph> |
|
|
An example of a |
|
|
<subscript> |
|
|
default |
|
|
role. |
|
|
|
|
|
Custom roles may be used (see the "role_" directive above), but it |
|
|
must have been declared in a document before it can be set as the |
|
|
default role. See the `reStructuredText Interpreted Text Roles`_ |
|
|
document for details of built-in roles. |
|
|
|
|
|
The directive may be used without an argument to restore the initial |
|
|
default interpreted text role, which is application-dependent. The |
|
|
initial default interpreted text role of the standard reStructuredText |
|
|
parser is "title-reference". |
|
|
|
|
|
|
|
|
Metadata Document Title |
|
|
======================= |
|
|
|
|
|
:Directive Type: "title" |
|
|
:Doctree Element: None. |
|
|
:Directive Arguments: 1, required (the title text). |
|
|
:Directive Options: None. |
|
|
:Directive Content: None. |
|
|
|
|
|
The "title" directive specifies the document title as metadata, which |
|
|
does not become part of the document body. It overrides a |
|
|
document-supplied title. For example, in HTML output the metadata |
|
|
document title appears in the title bar of the browser window. |

Restructuredtext-Test-Directive |
|
|
=============================== |
|
|
|
|
|
:Directive Type: "restructuredtext-test-directive" |
|
|
:Doctree Element: system_warning |
|
|
:Directive Arguments: None. |
|
|
:Directive Options: None. |
|
|
:Directive Content: Interpreted as a literal block. |
|
|
|
|
|
This directive is provided for test purposes only. (Nobody is |
|
|
expected to type in a name *that* long!) It is converted into a |
|
|
level-1 (info) system message showing the directive data, possibly |
|
|
followed by a literal block containing the rest of the directive |
|
|
block. |
|
|
|
|
|
-------------- |
|
|
Common Options |
|
|
-------------- |
|
|
|
|
|
Most of the directives that generate doctree elements support the following |
|
|
options: |
|
|
|
|
|
_`:class:` : text |
|
|
Set a `"classes"`_ attribute value on the doctree element generated by |
|
|
the directive. See also the class_ directive. |
|
|
|
|
|
_`:name:` : text |
|
|
Add `text` to the `"names"`_ attribute of the doctree element generated |
|
|
by the directive. This allows `hyperlink references`_ to the element |
|
|
using `text` as `reference name`_. |
|
|
|
|
|
Specifying the `name` option of a directive, e.g., :: |
|
|
|
|
|
.. image:: bild.png |
|
|
:name: my picture |
|
|
|
|
|
is a concise syntax alternative to preceding it with a `hyperlink |
|
|
target`_ :: |
