|
* Fixed my mess in EncodingManager.
|
||
|
* Changed many C casts to C++ casts.
|

|
*
|
||
|
* Revision 1.1 2003/01/24 05:52:31 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 1.7 2002/09/19 05:31:15 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 1.6 2002/09/17 03:03:28 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 *
|
||

|
* Removed newMain.c from GNUmakefile.am
|
||
|
*
|
||
|
* C++ comments are not C comment. Changed to C comments
|
||
|
*
|
||
|
* 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

|
||
|
* Spell dialog enabled by default, with keyboard binding of F7.
|

|
*
|
||
|
* Revision 1.1 1999/09/29 23:33:32 justin
|
||
|
* Updates to the underlying ispell-based code to support suggested corrections.
|
||
|
*
|
||
|
* Revision 1.59 1995/08/05 23:19:43 geoff
|
||
|
* Fix a bug that caused offsets for long lines to be confused if the
|
||
|
* line started with a quoting uparrow.
|
||
|
*
|
||
|
* Revision 1.58 1994/11/02 06:56:00 geoff
|
||
|
* Remove the anyword feature, which I've decided is a bad idea.
|
||
|
*
|
||
|
* Revision 1.57 1994/10/26 05:12:39 geoff
|
||
|
* Try boundary characters when inserting or substituting letters, except
|
||
|
* (naturally) at word boundaries.
|
||
|
*
|
||
|
* Revision 1.56 1994/10/25 05:46:30 geoff
|
||
|
* Fix an assignment inside a conditional that could generate spurious
|
||
|
* warnings (as well as being bad style). Add support for the FF_ANYWORD
|
||
|
* option.
|
||
|
*
|
||
|
* Revision 1.55 1994/09/16 04:48:24 geoff
|
||
|
* Don't pass newlines from the input to various other routines, and
|
||
|
* don't assume that those routines leave the input unchanged.
|
||
|
*
|
||
|
* Revision 1.54 1994/09/01 06:06:41 geoff
|
||
|
* Change erasechar/killchar to uerasechar/ukillchar to avoid
|
||
|
* shared-library problems on HP systems.
|
||
|
*
|
||
|
* Revision 1.53 1994/08/31 05:58:38 geoff
|
||
|
* Add code to handle extremely long lines in -a mode without splitting
|
||
|
* words or reporting incorrect offsets.
|
||
|
*
|
||
|
* Revision 1.52 1994/05/25 04:29:24 geoff
|
||
|
* Fix a bug that caused line widths to be calculated incorrectly when
|
||
|
* displaying lines containing tabs. Fix a couple of places where
|
||
|
* characters were sign-extended incorrectly, which could cause 8-bit
|
||
|
* characters to be displayed wrong.
|
||
|
*
|
||
|
* Revision 1.51 1994/05/17 06:44:05 geoff
|
||
|
* Add support for controlled compound formation and the COMPOUNDONLY
|
||
|
* option to affix flags.
|
||
|
*
|
||
|
* Revision 1.50 1994/04/27 05:20:14 geoff
|
||
|
* Allow compound words to be formed from more than two components
|
||
|
*
|
||
|
* Revision 1.49 1994/04/27 01:50:31 geoff
|
||
|
* Add support to correctly capitalize words generated as a result of a
|
||
|
* missing-space suggestion.
|
||
|
*
|
||
|
* Revision 1.48 1994/04/03 23:23:02 geoff
|
||
|
* Clean up the code in missingspace() to be a bit simpler and more
|
||
|
* efficient.
|
||
|
*
|
||
|
* Revision 1.47 1994/03/15 06:24:23 geoff
|
||
|
* Fix the +/-/~ commands to be independent. Allow the + command to
|
||
|
* receive a suffix which is a deformatter type (currently hardwired to
|
||
|
* be either tex or nroff/troff).
|
||
|
*
|
||
|
* Revision 1.46 1994/02/21 00:20:03 geoff
|
||
|
* Fix some bugs that could cause bad displays in the interaction between
|
||
|
* TeX parsing and string characters. Show_char now will not overrun
|
||
|
* the inverse-video display area by accident.
|
||
|
*
|
||
|
* Revision 1.45 1994/02/14 00:34:51 geoff
|
||
|
* Fix correct to accept length parameters for ctok and itok, so that it
|
||
|
* can pass them to the to/from ichar routines.
|
||
|
*
|
||
|
* Revision 1.44 1994/01/25 07:11:22 geoff
|
||
|
* Get rid of all old RCS log lines in preparation for the 3.1 release.
