Estructura
Déjame decir desde el principio que “Structured Text” (Texto estructurado) es probablemente un nombre engañoso.
From the outset, let me say that “Structured Text” is probably a bit of a misnomer. 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. It’s quite short.
This paragraph will result in an indented block of text, typically used for quoting other text. This is another one.
Text styles (quickref)
Inside paragraphs and other bodies of text, you may additionally mark text for italics with “italics” or bold with “bold”. This is called “inline markup”.
If you want something to appear as a fixed-space literal, use “double back-quotes”. 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 lone asterisk * is handled just fine, as is the asterisk in this equation: 56=30. 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:
*
Tip
Think of inline markup as a form of (parentheses) and use it the same way: immediately before and after the text being marked up. Inline markup by itself (surrounded by whitespace) or in the middle of a word won’t be recognized. See the markup spec for full details.
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) Start a line off with a number or letter followed by a period “.”, right bracket “)” or surrounded by brackets “( )” – whatever you’re comfortable with. All of the following forms are recognised:
- numbers
A. upper-case letters and it goes over many lines
with two paragraphs and all!
a. lower-case letters
- with a sub-list starting at a different number
- make sure the numbers are in the correct sequence though!
I. upper-case roman numerals
i. lower-case roman numerals
(1) numbers again
1) and again Results in (note: the different enumerated list styles are not always supported by every web browser, so you may not get the full effect here):
numbers upper-case letters and it goes over many lines
with two paragraphs and all!
lower-case letters with a sub-list starting at a different number make sure the numbers are in the correct sequence though! upper-case roman numerals lower-case roman numerals numbers again and again bulleted lists (quickref) Just like enumerated lists, start the line off with a bullet point character - either “-“, “+” or “*”:
-
a bullet point using “*”
-
a sub-list using “-“
- yet another sub-list
-
another item Results in:
-
a bullet point using “*” a sub-list using “-“ yet another sub-list another item definition lists (quickref) Unlike the other two, the definition lists consist of a term, and the definition of that term. 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)
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)
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:
