Abstract

This document is a demonstration of the reStructuredText markup language, containing examples of all basic reStructuredText constructs and many advanced constructs.

1 Structural Elements

1.1 Section Title

That's it, the text just above this line.

1.2 Transitions

Here's a transition:

It divides the section.

2 Body Elements

2.1 Paragraphs

A paragraph.

2.1.1 Inline Markup

Paragraphs contain text and may contain inline markup: emphasis, strong emphasis, inline literals, standalone hyperlinks (https://www.python.org), external hyperlinks (Python [5]), internal cross-references (example), external hyperlinks with embedded URIs (Python web site), footnote references (manually numbered [1], anonymous auto-numbered [3], labeled auto-numbered [2], or symbolic [*]), citation references ([CIT2002]), substitution references (EXAMPLE), and inline hyperlink targets (see Targets below for a reference back to here). Character-level inline markup is also possible (although exceedingly ugly!) in reStructuredText. Problems are indicated by |problematic| text (generated by processing errors; this one is intentional).

The default role for interpreted text is Title Reference. Here are some explicit interpreted text roles: a PEP reference (PEP 287); an RFC reference (RFC 2822); a subscript; a superscript; and explicit roles for standard inline markup.

Let's test wrapping and whitespace significance in inline literals: This is an example of --inline-literal --text, --including some-- strangely--hyphenated-words. Adjust-the-width-of-your-browser-window to see how the text is wrapped. -- ---- -------- Now note the spacing between the words of this sentence (words should be grouped in pairs).

If the --pep-references option was supplied, there should be a live link to PEP 258 here.

2.2 Bullet Lists

  • A bullet list

    • Nested bullet list.

    • Nested item 2.

  • Item 2.

    Paragraph 2 of item 2.

    • Nested bullet list.

    • Nested item 2.

      • Third level.

      • Item 2.

    • Nested item 3.

2.3 Enumerated Lists

  1. Arabic numerals.

    1. lower alpha)

      1. (lower roman)

        1. upper alpha.

          1. upper roman)

  2. Lists that don't start at 1:

    1. Three

    2. Four

    1. C

    2. D

    1. iii

    2. iv

  3. List items may also be auto-enumerated.

2.4 Definition Lists

Termclassifier

2.5 Field Lists

what:

Field lists map field names to field bodies, like database records. They are often part of an extension syntax. They are an unambiguous variant of RFC 2822 fields.

how arg1 arg2:

The field marker is a colon, the field name, and a colon.

The field body may contain one or more body elements, indented relative to the field marker.

2.6 Option Lists

For listing command-line options:

-a

command-line option "a"

-b file

options can have arguments and long descriptions

--long

options can be long also

--input=file

long options can also have arguments

--very-long-option

The description can also start on the next line.

The description may contain multiple body elements, regardless of where it starts.

-x, -y, -z

Multiple options are an "option group".

-v, --verbose

Commonly-seen: short & long options.

-1 file, --one=file, --two file

Multiple options with arguments.

/V

DOS/VMS-style options too

There must be at least two spaces between the option and the description.

2.7 Literal Blocks

Literal blocks are indicated with a double-colon ("::") at the end of the preceding paragraph (over there -->). They can be indented:

if literal_block:
    text = 'is left as-is'
    spaces_and_linebreaks = 'are preserved'
    markup_processing = None

Or they can be quoted without indentation:

>> Great idea!
>
> Why didn't I think of that?

2.8 Line Blocks

This is a line block. It ends with a blank line.
Each new line begins with a vertical bar ("|").
Line breaks and initial indents are preserved.
Continuation lines are wrapped portions of long lines; they begin with a space in place of the vertical bar.
The left edge of a continuation line need not be aligned with the left edge of the text above it.
This is a second line block.

Blank lines are permitted internally, but they must begin with a "|".

Take it away, Eric the Orchestra Leader!

A one, two, a one two three four

Half a bee, philosophically,
must, ipso facto, half not be.
But half the bee has got to be,
vis a vis its entity. D'you see?

But can a bee be said to be
or not to be an entire bee,
when half the bee is not a bee,
due to some ancient injury?

Singing...

2.9 Block Quotes

Block quotes consist of indented body elements:

My theory by A. Elk. Brackets Miss, brackets. This theory goes as follows and begins now. All brontosauruses are thin at one end, much much thicker in the middle and then thin again at the far end. That is my theory, it is mine, and belongs to me and I own it, and what it is too.

—Anne Elk (Miss)

2.10 Doctest Blocks

>>> print 'Python-specific usage examples; begun with ">>>"'
Python-specific usage examples; begun with ">>>"
>>> print '(cut and pasted from interactive Python sessions)'
(cut and pasted from interactive Python sessions)

2.11 Tables

Here's a grid table followed by a simple table:

Header row, column 1 (header rows optional)

Header 2

Header 3

Header 4

body row 1, column 1

column 2

column 3

column 4

body row 2

Cells may span columns.

body row 3

Cells may span rows.

2.12 Footnotes

2.13 Citations

[CIT2002] (1,2)

Citations are text-labeled footnotes. They may be rendered separately and differently from footnotes.

Here's a reference to the above, [CIT2002], and a [nonexistent]_ citation.

2.14 Targets

This paragraph is pointed to by the explicit "example" target. A reference can be found under Inline Markup, above. Inline hyperlink targets are also possible.

Section headers are implicit targets, referred to by name. See Targets, which is a subsection of Body Elements.

Explicit external targets are interpolated into references such as "Python [5]".

Targets may be indirect and anonymous. Thus this phrase may also refer to the Targets section.

Here's a `hyperlink reference without a target`_, which generates an error.

2.14.1 Duplicate Target Names

Duplicate names in section headers or other implicit targets will generate "info" (level-1) system messages. Duplicate names in explicit targets will generate "warning" (level-2) system messages.

2.14.2 Duplicate Target Names

Since there are two "Duplicate Target Names" section headers, we cannot uniquely refer to either of them by name. If we try to (like this: `Duplicate Target Names`_), an error is generated.

2.15 Directives

These are just a sample of the many reStructuredText Directives. For others, please see https://docutils.sourceforge.io/docs/ref/rst/directives.html.

2.15.1 Document Parts

An example of the "contents" directive can be seen above this section (a local, untitled table of contents) and at the beginning of the document (a document-wide table of contents).

2.15.2 Images

An image directive (also clickable -- a hyperlink reference):

images/title.png

A figure directive:

reStructuredText, the markup syntax

A figure is an image with a caption and/or a legend:

re

Revised, revisited, based on 're' module.

Structured

Structure-enhanced text, structuredtext.

Text

Well it is, isn't it?

This paragraph is also part of the legend.

2.15.3 Admonitions

2.15.4 Topics, Sidebars, and Rubrics

This is a rubric

2.15.5 Target Footnotes

2.15.6 Replacement Text

I recommend you try Python, the best language around [5].

2.15.7 Compound Paragraph

This paragraph contains a literal block:

Connecting... OK
Transmitting data... OK
Disconnecting... OK

and thus consists of a simple paragraph, a literal block, and another simple paragraph. Nonetheless it is semantically one paragraph.

This construct is called a compound paragraph and can be produced with the "compound" directive.

2.15.8 Meta

The “meta” directive [6] is used to specify metadata to be stored in, e.g., HTML META [7] tags or ODT file properties.

2.16 Substitution Definitions

An inline image (EXAMPLE) example:

(Substitution definitions are not visible in the HTML source.)

2.17 Comments

Here's one:

3 Error Handling

Any errors caught during processing will generate system messages.

|*** Expect 6 errors (including this one). ***|

There should be six messages in the following, auto-generated section, "Docutils System Messages":
