Structured Text

Structured text is text that uses indentation and simple
symbology to indicate the structure of a document. For the next generation of structured text, see here.

A structured string consists of a sequence of paragraphs separated by
one or more blank lines. Each paragraph has a level which is defined
as the minimum indentation of the paragraph. A paragraph is a
sub-paragraph of another paragraph if the other paragraph is the last
preceding paragraph that has a lower level.

Special symbology is used to indicate special constructs:

• A single-line paragraph whose immediately succeeding paragraphs are lower level is treated as a header.
  
  
• A paragraph that begins with a '-', '*', or 'o' is treated as an unordered list (bullet) element.
  
  
• A paragraph that begins with a sequence of digits followed by a white-space character is treated as an ordered list element.
  
  
• A paragraph that begins with a sequence of sequences, where each sequence is a sequence of digits or a sequence of letters followed by a period, is treated as an ordered list element.
  
  
• A paragraph with a first line that contains some text, followed by some white-space and '--' is treated as a descriptive list element. The leading text is treated as the element title.
  
  
• Sub-paragraphs of a paragraph that ends in the word 'example' or the word 'examples', or '::' is treated as example code and is output as is.
  
  
• Text enclosed single quotes (with white-space to the left of the first quote and whitespace or puctuation to the right of the second quote) is treated as example code.
  
  
• Text surrounded by '*' characters (with white-space to the left of the first '*' and whitespace or puctuation to the right of the second '*') is emphasized.
  
  
• Text surrounded by '**' characters (with white-space to the left of the first '**' and whitespace or puctuation to the right of the second '**') is made strong.
  
  
• Text surrounded by '_' underscore characters (with whitespace to the left and whitespace or punctuation to the right) is made underlined.
  
  
• Text encloded by double quotes followed by a colon, a URL, and concluded by punctuation plus white space, *or* just white space, is treated as a hyper link. For example:
  
  
  "Zope":http://www.zope.org/ is ...
  
  
Is interpreted as '<a href="http://www.zope.org/">Zope</a> is ....'

Note: This works for relative as well as absolute URLs.


• Text enclosed by double quotes followed by a comma, one or more spaces, an absolute URL and concluded by punctuation plus white space, or just white space, is treated as a hyper link. For example:
  
  
  "mail me", amos@digicool.com.
  
  
Is interpreted as '<a href="amos@digicool.com">mail me</a>.'


• Text enclosed in brackets which consists only of letters, digits, underscores and dashes is treated as hyper links within the document. For example:
  
  
  As demonstrated by Smith 12 this technique is quite effective.
  
  
Is interpreted as '... by Smith <a href="#12">12</a> this ...'. Together with the next rule this allows easy coding of references or end notes.


• Text enclosed in brackets which is preceded by the start of a line, two periods and a space is treated as a named link. For example:
  
  
  .. 12 "Effective Techniques" Smith, Joe ...
  
  
Is interpreted as '<a name="12">12</a> "Effective Techniques" ...'. Together with the previous rule this allows easy coding of references or end notes.



• A paragraph that has blocks of text enclosed in '||' is treated as a table. The text blocks correspond to table cells and table rows are denoted by newlines. By default the cells are center aligned. A cell can span more than one column by preceding a block of text with an equivalent number of cell separators '||'. Newlines and '|' cannot be a part of the cell text. For example:
  
  
  

  ~cpp 
  |||| **Ingredients** ||
  || *Name* || *Amount* ||
  ||Spam||10||
  ||Eggs||3||
  

  
  
renders like this:


**Ingredients**
*Name*	*Amount*
Spam	10
Eggs	3
