Most + * of this is a hack. + * + * 1. added other/spell to the -I list in config/abi_defs + * 2. replaced other/spell/Makefile with one which is more like + * our build system. + * 3. added other/spell to other/Makefile so that the build will now + * dive down and build the spell check library. + * 4. added the AbiSpell library to the Makefiles in wp/main + * 5. added a call to SpellCheckInit in wp/main/unix/UnixMain.cpp. + * This call is a HACK and should be replaced with something + * proper later. + * 6. added code to fv_View.cpp as follows: + * whenever you double-click on a word, the spell checker + * verifies that word and prints its status to stdout. + * + * Caveats: + * 1. This will break the Windows build. I'm going to work on fixing it + * now. + * 2. This only works if your dictionary is in /usr/lib/ispell/american.hash. + * The dictionary location is currently hard-coded. This will be + * fixed as well. + * + * Anyway, such as it is, it works. + * + * 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 1.32 1994/11/02 06:56:16 geoff + * Remove the anyword feature, which I've decided is a bad idea. + * + * Revision 1.31 1994/10/25 05:46:25 geoff + * Add support for the FF_ANYWORD (affix applies to all words, even if + * flag bit isn't set) flag option. + * + * Revision 1.30 1994/05/24 06:23:08 geoff + * Don't create a hit if "allhits" is clear and capitalization + * mismatches.
