- ;;; Spelling correction interface for GNU EMACS "ispell"
- ;;; Id: ispell.el,v 2.20 1993/03/31 00:32:53 jwz Exp
- ;;;
- ;;; Log: ispell.el,v
- ;;; Revision 2.20 1993/03/31 00:32:53 jwz
- ;;; Added Lucid Emacs support.
- ;;; Added version checking to detect mismatches between ispell.el and
- ;;; ispell.c instead of failing silently.
- ;;; Added a save-excursion to ispell-word so that it doesn't move the
- ;;; cursor to the beginning of the word, which was just too damn annoying.
- ;;; Made it position the cursor at the end of the word instead of the
- ;;; beginning, since that looks better.
- ;;; ispell-complete (really, lookup-words) didn't work for me at all,
- ;;; so I rewrote it in a simpler way.
- ;;;
- ;;; Revision 2.19 1992/01/10 10:54:08 geoff
- ;;; Make another attempt at fixing the "Bogus, dude" problem. This one is
- ;;; less elegant, but has the advantage of working.
- ;;;
- ;;; Revision 2.18 1992/01/07 10:04:52 geoff
- ;;; Fix the "Bogus, Dude" problem in ispell-word.
- ;;;
- ;;; Revision 2.17 91/09/12 00:01:42 geoff
- ;;; Add some changes to make ispell-complete-word work better, though
- ;;; still not perfectly.
- ;;;
- ;;; Revision 2.16 91/09/04 18:00:52 geoff
- ;;; More updates from Sebastian, to make the multiple-dictionary support
- ;;; more flexible.
- ;;;
- ;;; Revision 2.15 91/09/04 17:30:02 geoff
- ;;; Sebastian Kremer's tib support
- ;;;
- ;;; Revision 2.14 91/09/04 16:19:37 geoff
- ;;; Don't do set-window-start if the move-to-window-line moved us
- ;;; downward, rather than upward. This prevents getting the buffer all
- ;;; confused. Also, don't use the "not-modified" function to clear the
- ;;; modification flag; instead use set-buffer-modified-p. This prevents
- ;;; extra messages from flashing.
- ;;;
- ;;; Revision 2.13 91/09/04 14:35:41 geoff
- ;;; Fix a spelling error in a comment. Add code to handshake with the
- ;;; ispell process before sending anything to it.
- ;;;
- ;;; Revision 2.12 91/09/03 20:14:21 geoff
- ;;; Add Sebastian Kremer's multiple-language support.

- ;;; This file has overgone a major overhaul to be compatible with ispell
- ;;; version 2.1. Most of the functions have been totally rewritten, and
- ;;; many user-accessible variables have been added. The syntax table has
- ;;; been removed since it didn't work properly anyway, and a filter is
- ;;; used rather than a buffer. Regular expressions are used based on
- ;;; ispell's internal definition of characters (see ispell(4)).

- ;;; Tue Jan 3 16:59:07 PST 1989
- ;;; Some new updates:
- ;;; - Updated to version 3.0 to include terse processing.
- ;;; - Added a variable for the look command.
- ;;; - Fixed a bug in ispell-word when cursor is far away from the word
- ;;; that is to be checked.
- ;;; - Ispell places the incorrect word or guess in the minibuffer now.
- ;;; - fixed a bug with 'l' option when multiple windows are on the screen.
- ;;; - lookup-words just didn't work with the process filter. Fixed.
- ;;; - Rewrote the process filter to make it cleaner and more robust
- ;;; in the event of a continued line not being completed.
- ;;; - Made ispell-init-process more robust in handling errors.
- ;;; - Fixed bug in continuation location after a region has been modified by
- ;;; correcting a misspelling.

- ;;; Wed Aug 7 14:02:17 MET DST 1991
- ;;; - Ported ispell-complete-word from Ispell 2 to Ispell 3.
- ;;; - Added ispell-kill-ispell command.
- ;;; - Added ispell:dictionary and ispell:dictionary-alist variables to
- ;;; support other than default language. See their docstrings and
- ;;; command ispell-change-dictionary.
- ;;; - (ispelled it :-)
- ;;; - Added ispell:check-tib variable to support the tib bibliography
- ;;; program.
