* $Log$
* Revision 1.2 2004/02/01 04:46:46 zrusin
* Both ispell and aspell plugins are not working properly. We can start switching.
*
* Revision 1.1 2004/01/31 16:44:12 zrusin
* ISpell plugin.
*
* Revision 1.4 2003/08/14 17:51:28 dom
* update license - exception clause should be Lesser GPL
*
* Revision 1.3 2003/07/28 20:40:27 dom
* fix up the license clause, further win32-registry proof some directory getting functions
*
* Revision 1.2 2003/07/16 22:52:49 dom
* LGPL + exception license
*
* Revision 1.1 2003/07/15 01:15:08 dom
* ispell enchant backend
*
* Revision 1.3 2003/02/12 02:10:38 hippietrail
*
* C casts -> C++ casts
* Improved const-correctness due to changing casts
* Fixed some warnings
*
* Revision 1.2 2003/01/29 05:50:12 hippietrail
*
* Fixed my mess in EncodingManager.
* Changed many C casts to C++ casts.
*
* Revision 1.1 2003/01/24 05:52:35 hippietrail
*
* Refactored ispell code. Old ispell global variables had been put into
* an allocated structure, a pointer to which was passed to many functions.
* I have now made all such functions and variables private members of the
* ISpellChecker class. It was C OO, now it's C++ OO.
*
* I've fixed the makefiles and tested compilation but am unable to test
* operation. Please back out my changes if they cause problems which
* are not obvious or easy to fix.
*
* Revision 1.8 2003/01/06 18:48:40 dom
* ispell cleanup, start of using new 'add' save features
*
* Revision 1.7 2003/01/04 19:09:04 dom
* some tidying... bug pissing me off...
*
* Revision 1.6 2002/09/19 05:31:18 hippietrail
*
* More Ispell cleanup. Conditional globals and DEREF macros are removed.
* K&R function declarations removed, converted to Doxygen style comments
* where possible. No code has been changed (I hope). Compiles for me but
* unable to test.
*
* Revision 1.5 2002/09/17 03:03:30 hippietrail
*
* After seeking permission on the developer list I've reformatted all the
* spelling source which seemed to have parts which used 2, 3, 4, and 8
* spaces for tabs. It should all look good with our standard 4-space
* tabs now.
* I've concentrated just on indentation in the actual code. More prettying
* could be done.
* * NO code changes were made *
*
* Revision 1.4 2002/09/13 17:20:13 mpritchett
* Fix more warnings for Linux build
*
* Revision 1.3 2002/03/22 14:31:57 dom
* fix mg's compile problem
*
* Revision 1.2 2001/05/12 16:05:42 thomasf
* Big pseudo changes to ispell to make it pass around a structure rather
* than rely on all sorts of gloabals willy nilly here and there. Also
* fixed our spelling class to work with accepting suggestions once more.
* This code is dirty, gross and ugly (not to mention still not supporting
* multiple hash sized just yet) but it works on my machine and will no
* doubt break other machines.
*
* Revision 1.1 2001/04/15 16:01:24 tomas_f
* moving to spell/xp
*
* Revision 1.6 1999/12/21 18:46:29 sterwill
* ispell patch for non-English dictionaries by Henrik Berg <henrik@lansen.se>
*
* Revision 1.5 1999/10/20 03:19:35 paul
* Hacked ispell code to ignore any characters that don't fit in the lookup tables loaded from the dictionary. It ain't pretty, but at least we don't crash there any more.
*
* Revision 1.4 1999/04/13 17:12:51 jeff
* Applied "Darren O. Benham" <gecko@benham.net> spell check changes.
* Fixed crash on Win32 with the new code.
*
* Revision 1.3 1998/12/29 14:55:33 eric
*
* I've doctored the ispell code pretty extensively here. It is now
* warning-free on Win32. It also *works* on Win32 now, since I
* replaced all the I/O calls with ANSI standard ones.

*
* I've doctored the ispell code pretty extensively here. It is now
* warning-free on Win32. It also *works* on Win32 now, since I
* replaced all the I/O calls with ANSI standard ones.
*
* Revision 1.2 1998/12/28 23:11:30 eric
*
* modified spell code and integration to build on Windows.
* This is still a hack.
*
* Actually, it doesn't yet WORK on Windows. It just builds.
* SpellCheckInit is failing for some reason.
*
* Revision 1.1 1998/12/28 18:04:43 davet
* Spell checker code stripped from ispell. At this point, there are
* two external routines... the Init routine, and a check-a-word routine
* which returns a boolean value, and takes a 16 bit char string.
* The code resembles the ispell code as much as possible still.
*
* Revision 1.45 1994/12/27 23:08:52 geoff
* Add code to makedent to reject words that contain non-word characters.
* This helps protect people who use ISO 8-bit characters when ispell
* isn't configured for that option.
*
* Revision 1.44 1994/10/25 05:46:20 geoff
* Fix some incorrect declarations in the lint versions of some routines.
*
* Revision 1.43 1994/09/16 03:32:34 geoff
* Issue an error message for bad affix flags
*
* Revision 1.42 1994/02/07 04:23:43 geoff
* Correctly identify the deformatter when changing file types
*
* Revision 1.41 1994/01/25 07:11:55 geoff
* Get rid of all old RCS log lines in preparation for the 3.1 release.

** Combine and resolve the entries describing two capitalizations of the same
** word. This may require allocating yet more entries.
**
** Hdrp is a pointer into a hash table. If the word covered by hdrp has
** variations, hdrp must point to the header. Newp is a pointer to temporary
** storage, and space is malloc'ed if newp is to be kept. The newp->word
** field must have been allocated with mymalloc, so that this routine may free
** the space if it keeps newp but not the word.
**
** Return value: 0 if the word was added, 1 if the word was combined
** with an existing entry, and -1 if trouble occurred (e.g., malloc).
** If 1 is returned, newp->word may have been be freed using myfree.
**
** Life is made much more difficult by the KEEP flag's possibilities. We
** must ensure that a !KEEP word doesn't find its way into the personal
** dictionary as a result of this routine's actions. However, a !KEEP
** word that has affixes must have come from the main dictionary, so it
** is acceptable to combine entries in that case (got that?).
**
** The net result of all this is a set of rules that is a bloody pain
** to figure out. Basically, we want to choose one of the following actions:
**
** (1) Add newp's affixes and KEEP flag to oldp, and discard newp.
** (2) Add oldp's affixes and KEEP flag to newp, replace oldp with
** newp, and discard newp.
#ifndef NO_CAPITALIZATION_SUPPORT
** (3) Insert newp as a new entry in the variants list. If there is
** currently no variant header, this requires adding one. Adding a
** header splits into two sub-cases:
**
** (3a) If oldp is ALLCAPS and the KEEP flags match, just turn it
** into the header.
** (3b) Otherwise, add a new entry to serve as the header.
** To ease list linking, this is done by copying oldp into
** the new entry, and then performing (3a).
**
** After newp has been added as a variant, its affixes and KEEP
** flag are OR-ed into the variant header.
#endif
**
** So how to choose which? The default is always case (3), which adds newp
** as a new entry in the variants list. Cases (1) and (2) are symmetrical
** except for which entry is discarded. We can use case (1) or (2) whenever
** one entry "covers" the other. "Covering" is defined as follows:
**
** (4) For entries with matching capitalization types, A covers B
** if:
**
** (4a) B's affix flags are a subset of A's, or the KEEP flags
** match, and
** (4b) either the KEEP flags match, or A's KEEP flag is set.
** (Since A has more suffixes, combining B with it won't
** cause any extra suffixes to be added to the dictionary.)
** (4c) If the words are FOLLOWCASE, the capitalizations match
** exactly.
**
#ifndef NO_CAPITALIZATION_SUPPORT
** (5) For entries with mismatched capitalization types, A covers B
** if (4a) and (4b) are true, and:
**
** (5a) B is ALLCAPS, or
** (5b) A is ANYCASE, and B is CAPITALIZED.
#endif
**
** For any "hdrp" without variants, oldp is the same as hdrp. Otherwise,
** the above tests are applied using each variant in turn for oldp.
