/* wjc sez....

This algorithm is based on my observation of how people actually use
quotation marks, sometimes in contravention of generally accepted
principles of punctuation.  It is certainly also true that my
observations are overwhelmingly of American English text, with a
smattering of various other languages observed from time to time.  I
don't believe that any algorithm for this can ever be perfect.  There
are too many infrequently-occurring but legitimate cases where a user
might want something else.  FWIW, I haven't tested out the specifics
of the smart quote algorithm in ThatOtherWordProcessor.

Some terms for the purpose of this discussion (I'm open to plenty of
advice on what specific items should fit in each of these classes):

sqBREAK  A structural break in a document.  For example, a paragraph
  break, a column break, a page break, the beginning or end of a
  document, etc.  Does not include font, size, bold/italic/underline
  changes (which are completely ignored for the purposes of this
  algorithm).

sqFOLLOWPUNCT A subset of layman's "punctuation".  I include only
  things that can normally occur after a quote mark with no intervening
  white space.  Includes period, exclamation point, question mark,
  semi-colon, colon, comma (but not parentheses, square and curly
  brackets, which are treated specially below).  There may be a few
  others that aren't on the kinds of keyboards I use, and there are
  certainly Latin1 and other locale-specific variants, but the point
  is that there are lots of random non-alphanumerics which aren't
  included in *PUNCT for this algorithm.

sqOPENPUNCT  The opening half of pairwise, non-quote punctuation.  Open
  parenthesis, open square bracket, open curly brace.

sqCLOSEPUNCT  The closing half of pairwise, non-quote punctuation.  Close
  parenthesis, close square bracket, close curly brace.

[[The idea about open and close punctuation was found in a mid-1980s
note by Dave Dunham, brought to my attention by Leonard Rosenthol
<leonardr@lazerware.com>.]]

sqOTHERPUNCT  Punctuation which is not sqFOLLOWPUNCT, sqOPENPUNCT, or
  sqCLOSEPUNCT.

sqALPHA  Alphabetic characters in the C isalpha() sense, but there are
  certainly some non-ASCII letter characters which belong in this
  bucket, too.

sqWHITE  White speace haracters in the C isspace() sense.

QUOTE  Any of ASCII double quote, ASCII quote (which many people call
  the ASCII single quote or the ASCII apostrophe), or ASCII backquote.
  I take it as given that a significant minority of people randomly or
  systematically interchange their use of ASCII quote and ASCII
  backquote, so I treat them the same in the algorithm.  The majority
  of people use ASCII quote for both opening and closing single quote.

PARITY  Whether a quote is single or double.  For ease of description,
  I'll say that the parity of single and double quotes are opposites
  of each other.  When QUOTEs are converted to curly form, the parity
  never changes.

================================================================

Given a QUOTE character, these conditions/rules are logically tested in
order:

0.  OK, first an easy exception case: If ASCII (single) quote (but not
ASCII backquote) appears between two sqALPHAs, it may be treated as an
apostrophe and converted to its curly form.  Otherwise, it is treated
like all other QUOTEs and follows the normal algorithm.

1.  If a QUOTE is immediately preceded by a curly quote of opposite
parity, it is converted to a curly quote in the same direction.

2.  If a QUOTE is immediately preceded by a curly quote of the same
parity, it is converted to a curly quote of opposite direction.

3.  If a QUOTE is immediately followed by a curly quote of opposite
parity, it is converted to a curly quote in the same direction.

4.  If a QUOTE is immediately followed by a curly quote of the same
parity, it is converted to a curly quote of opposite direction.

[[The above cases are intended to handle normal nested quotes or cases
where quotes enclose empty strings.  Different cultures use different
parities as start points for nested quotes, but the algorithm doesn't
care.]]

5.  If a QUOTE is immediately preceded by an sqOPENPUNCT, it is
converted to a curly quote in the open direction.

6.  If a QUOTE is immediately followed by a sqCLOSEPUNCT, it is
converted to a curly quote in the close direction.

7.  If a QUOTE is in isolation, it is converted to a curly quote
in the open direction.  It is in isolation if it is immediately
preceded and followed by either a sqBREAK or sqWHITE.  The things
before and after it don't have to be of the same type.

Rule 7 was originally that it didin't convert.  This does not make
sense because the most common use of smart quotes is as you're typing
where there is often a space before and nothing after (since it hasn't
been written yet!) -- Bobby Weinmann Feb 4, 2008

8.  If a QUOTE is immediately preceded by a sqBREAK or sqWHITE and
is immediately followed by anything other than a sqBREAK or sqWHITE,
it is converted to the opening form of curly quote.

9.  If a QUOTE is immediately followed by a sqBREAK, sqWHITE, or
sqFOLLOWPUNCT and is immediately preceded by anything other than sqBREAK
or sqWHITE, it is converted to the closing form of curly quote.

10.  Any other QUOTE is not converted.

================================================================

The algorithm doesn't make a special case of using ASCII double quote
as an inches indicator (there are other uses, like lat/long minutes;
ditto for the ASCII quote) because it is tough to tell if some numbers
with an ASCII double quote after them are intended to be one of those
"other things" or is just the end of a very long quote.  So, the
algorithm will be wrong sometimes in those cases.

It is otherwise sort of conservative, preferring to not convert things
it doesn't feel confident about.  The reason for that is that there is
a contemplated on-the-fly conversion to smart quotes, but there is no
contemplated on-the-fly conversion to ASCII QUOTEs.  So, if the
algorithm makes a mistake by not converting, the user can correct it
by directly entering the appropriate smart quote character or by
heuristically tricking AbiWord into converting it for him/her and then
fixing things up.  (That heuristic step shouldn't be necessary, you
know, but I think we all use software for which we have become
accustomed to such things.)

What about the occasions when this algorithm (or any alternative
algorithm) makes a mistake and converts a QUOTE to the curly form when
it really isn't wanted, in a particular case, by the user?  Although
the user can change it back, some contemplated implementation details
might run around behind the barn and re-convert it when the user isn't
looking.  I think we need a mechanism for dealing with that, but I
want to save proposals for that to be separate from the basic
algorithm.
