Structured text is text that uses indentation and simple symbology to indicate the structure of a document. 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", mailto:am...@di.... Is interpreted as '<a href="mailto:am...@di...">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: |||| **Ingredients** || || *Name* || *Amount* || ||Spam||10|| ||Eggs||3|| is interpreted as:: <TABLE BORDER=1 CELLPADDING=2> <TR> <TD ALIGN=CENTER COLSPAN=2> <strong>Ingredients</strong> </TD> </TR> <TR> <TD ALIGN=CENTER COLSPAN=1> <em>Name</em> </TD> <TD ALIGN=CENTER COLSPAN=1> <em>Amount</em> </TD> </TR> <TR> <TD ALIGN=CENTER COLSPAN=1>Spam</TD> <TD ALIGN=CENTER COLSPAN=1>10</TD> </TR> <TR> <TD ALIGN=CENTER COLSPAN=1>Eggs</TD> <TD ALIGN=CENTER COLSPAN=1>3</TD> </TR> </TABLE> $Id: StructuredText.py,v 1.1 2003/06/05 03:53:52 dubnerm Exp $''' # Copyright # # Copyright 1996 Digital Creations, L.C., 910 Princess Anne # Street, Suite 300, Fredericksburg, Virginia 22401 U.S.A.
