'''Structured Text Manipulation
Parse a structured text string into a form that can be used with
structured formats, like html.
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:amos@digicool.com.
Is interpreted as '<a href="mailto: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:
|||| **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>

# Revision 1.24 1999/12/13 16:32:48 klm
# Incorporated pavlos christoforou's mods to handle simple tables. From
# his web page at http://www.zope.org/Members/gaaros/StructuredText:
#
# Structured Text module with table support
#
# 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. You can
# change the defaults by modifying the CELL,ROW and TABLE class
# attributes in class Table. 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. If you need
# newlines use <BR>. For example:
#
# |||| **Ingredients** ||
# || *Name* || *Amount* ||
# ||Spam||10||
# ||Eggs||3||
#
# Revision 1.23 1999/08/03 20:49:05 jim
# Fixed to allow list elements to introduce examples.
#
# Restructured _str using continue to avoid excessive nesting.
#
# Revision 1.22 1999/08/02 22:01:28 jim
# Fixed a bunch of bugs introduced by making ts_regex actually thread
# safe.
#
# Also localized a bunch of regular expressions
# using "static" variables (aka always default arguments).
#
# Revision 1.21 1999/08/02 13:26:52 jim
# paragraph_divider needs to be a regular (thread-unsafe) regex
# since it gets passed to ts_regex.split, which is thread-safe
# and wants to use regs.
#
# Revision 1.20 1999/07/21 13:33:59 jim
# untabified.
#
# Revision 1.19 1999/07/15 16:43:15 jim
# Checked in Scott Robertson's thread-safety fixes.
#
# Revision 1.18 1999/03/24 00:03:18 klm
# Provide for relative links, eg <a href="file_in_same_dir">whatever</a>,
# as:
#
# "whatever", :file_in_same_dir
#
# or
#
# "whatever"::file_in_same_dir
#
# .__init__(): relax the second gsub, using a '*' instead of a '+', so
# the stuff before the ':' can be missing, and also do postprocessing so
# any resulting '<a href=":file_in_same_dir">'s have the superfluous ':'
# removed. *Seems* good!
#
# Revision 1.17 1999/03/12 23:21:39 klm
# Gratuituous checkin to test my cvs *update* logging hook.
#
# Revision 1.16 1999/03/12 17:12:12 klm
# Added support for underlined elements, in the obvious way (and
# included an entry in the module docstring for it).
#
# Added an entry in the module docstring describing what i *guess* is
# the criterion for identifying header elements. (I'm going to have to
# delve into and understand the framework a bit better before *knowing*
# this is the case.)
#
# Revision 1.15 1999/03/11 22:40:18 klm
# Handle links that include '#' named links.
#
# Revision 1.14 1999/03/11 01:35:19 klm
# Fixed a small typo, and refined the module docstring link example, in
# order to do a checkin to exercise the CVS repository mirroring. Might
# as well include my last checkin message, with some substantial stuff:
#
# Links are now recognized whether or not the candidate strings are
# terminated with punctuation before the trailing whitespace. The old
# form - trailing punctuation then whitespace - is preserved, but the
# punctuation is now unnecessary.
#
# The regular expressions are a bit more complicated, but i've factored
# out the common parts and but them in variables with suggestive names,
# which may make them easier to understand.
#
# Revision 1.13 1999/03/11 00:49:57 klm
# Links are now recognized whether or not the candidate strings are
# terminated with punctuation before the trailing whitespace. The old

# Trival checkin (spelling fix "preceedeing" -> "preceding" and similar)
# to see what pitfalls my environment presents to accomplishing a
# successful checkin. (It turns out that i can't do it from aldous because
# the new version of cvs doesn't support the '-t' and '-f' options in the
