It strives to be readable in +its raw text +form, extensible, easy to write, and flexible in output. Writers +exist to output HTML, XHTML, LaTeX, and several other formats -:Author: Richard Jones -:Version: $Revision: 4350 $ -:Copyright: This document has been placed in the public domain. +reStructured text is closely tied to the python community and is used +in the formating of PEPs. The most popular implementation is `docutils`_. -.. contents:: - - -The text below contains links that look like "(quickref__)". These -are relative links that point to the `Quick reStructuredText`_ user -reference.

It's more like "Relaxed Text" that uses certain -consistent patterns. These patterns are interpreted by a HTML -converter to produce "Very Structured Text" that can be used by a web -browser. - -The most basic pattern recognised is a **paragraph** (quickref__). -That's a chunk of text that is separated by blank lines (one is -enough). Paragraphs must have the same indentation -- that is, line -up at their left edge. Paragraphs that start indented will result in -indented quote paragraphs. For example:: - - This is a paragraph. It's quite - short. - - This paragraph will result in an indented block of - text, typically used for quoting other text. - - This is another one. - -Results in: - - This is a paragraph.

Note that no further fiddling is done -inside the double back-quotes -- so asterisks "``*``" etc. are left -alone. - -If you find that you want to use one of the "special" characters in -text, it will generally be OK -- reStructuredText is pretty smart. -For example, this * asterisk is handled just fine. If you actually -want text \*surrounded by asterisks* to **not** be italicised, then -you need to indicate that the asterisk is not special. You do this by -placing a backslash just before it, like so "``\*``" (quickref__), or -by enclosing it in double back-quotes (inline literals), like this:: - - ``\*`` - -__ quickref.html#escaping - - -Lists ------ - -Lists of items come in three main flavours: **enumerated**, -**bulleted** and **definitions**. In all list cases, you may have as -many paragraphs, sublists, etc. as you want, as long as the left-hand -side of the paragraph or whatever aligns with the first line of text -in the list item. - -Lists must always start a new paragraph -- that is, they must appear -after a blank line. - -**enumerated** lists (numbers, letters or roman numerals; quickref__) - __ quickref.html#enumerated-lists - - Start a line off with a number or letter followed by a period ".", - right bracket ")" or surrounded by brackets "( )" -- whatever you're - comfortable with.

The format of a definition list is:: - - what - Definition lists associate a term with a definition. - - *how* - The term is a one-line phrase, and the definition is one or more - paragraphs or body elements, indented relative to the term. - Blank lines are not allowed between term and definition. - - Results in: - - what - Definition lists associate a term with a definition. - - *how* - The term is a one-line phrase, and the definition is one or more - paragraphs or body elements, indented relative to the term. - Blank lines are not allowed between term and definition. - - -Preformatting (code samples) ----------------------------- -(quickref__) - -__ quickref.html#literal-blocks - -To just include a chunk of preformatted, never-to-be-fiddled-with -text, finish the prior paragraph with "``::``". The preformatted -block is finished when the text falls back to the same indentation -level as a paragraph prior to the preformatted block. For example:: - - An example:: - - Whitespace, newlines, blank lines, and all kinds of markup - (like *this* or \this) is preserved by literal blocks. - Lookie here, I've dropped an indentation level - (but not far enough) - - no more example - -Results in: - - An example:: - - Whitespace, newlines, blank lines, and all kinds of markup - (like *this* or \this) is preserved by literal blocks. - Lookie here, I've dropped an indentation level - (but not far enough) - - no more example - -Note that if a paragraph consists only of "``::``", then it's removed -from the output:: - - :: - - This is preformatted text, and the - last "::" paragraph is removed - -Results in: - -:: - - This is preformatted text, and the - last "::" paragraph is removed - - -Sections --------- - -(quickref__) - -__ quickref.html#section-structure - -To break longer text up into sections, you use **section headers**. -These are a single line of text (one or more words) with adornment: an -underline alone, or an underline and an overline together, in dashes -"``-----``", equals "``======``", tildes "``~~~~~~``" or any of the -non-alphanumeric characters ``= - ` : ' " ~ ^ _ * + # < >`` that you -feel comfortable with. An underline-only adornment is distinct from -an overline-and-underline adornment using the same character. The -underline/overline must be at least as long as the title text. Be -consistent, since all sections marked with the same adornment style -are deemed to be at the same level:: - - Chapter 1 Title - =============== - - Section 1.1 Title - ----------------- - - Subsection 1.1.1 Title - ~~~~~~~~~~~~~~~~~~~~~~ - - Section 1.2 Title - ----------------- - - Chapter 2 Title - =============== - -This results in the following structure, illustrated by simplified -pseudo-XML:: - - <section> - <title> - Chapter 1 Title - <section> - <title> - Section 1.1 Title - <section> - <title> - Subsection 1.1.1 Title - <section> - <title> - Section 1.2 Title - <section> - <title> - Chapter 2 Title - -(Pseudo-XML uses indentation for nesting and has no end-tags. It's -not possible to show actual processed output, as in the other -examples, because sections cannot exist inside block quotes.

To link to the Lists_ heading, I write "``Lists_``". If -the heading has a space in it like `text styles`_, we need to quote -the heading "```text styles`_``". - - -Document Title / Subtitle -````````````````````````` - -The title of the whole document is distinct from section titles and -may be formatted somewhat differently (e.g. the HTML writer by default -shows it as a centered heading). - -To indicate the document title in reStructuredText, use a unique adornment -style at the beginning of the document. To indicate the document subtitle, -use another unique adornment style immediately after the document title. For -example:: - - ================ - Document Title - ================ - ---------- - Subtitle - ---------- - - Section Title - ============= - - ... - -Note that "Document Title" and "Section Title" above both use equals -signs, but are distict and unrelated styles. The text of -overline-and-underlined titles (but not underlined-only) may be inset -for aesthetics. - - -Images ------- - -(quickref__) - -__ quickref.html#directives - -To include an image in your document, you use the the ``image`` directive__. -For example:: - - .. image:: images/biohazard.png - -results in: - -.. image:: images/biohazard.png - -The ``images/biohazard.png`` part indicates the filename of the image -you wish to appear in the document.
