This emulation was widely distributed as the file edt.ml -;; in the maclib directory of most Emacs distributions. -;; -;; I will gladly take all criticisms and complaints to heart, and will fix what -;; bugs I can find. As this is my first Emacs Lisp hack, you may have to root -;; out a few nasties hidden in the code. Please let me know if you find any -;; (sorry, no rewards :-). I would also be interested if there are better, -;; cleaner, faster ways of doing some of the things that I have done. -;; -;; You must understand some design considerations that I had in mind. -;; The intention was not really to "emulate" EDT, but rather to take advantage -;; of the years of EDT experience that had accumulated in my right hand, -;; while at the same time taking advantage of EMACS. -;; -;; Some major differences are: -;; -;; HELP is describe-key; -;; GOLD/HELP is describe-function; -;; FIND is isearch-forward/backward; -;; GOLD/HELP is occur-menu, which finds all instances of a search string; -;; ENTER is other-window; -;; SUBS is subprocess-command. Note that you have to change this -;; to `shell' if you are running Un*x; -;; PAGE is next-paragraph, because that's more useful than page. -;; SPECINS is copy-to-killring; -;; GOLD/GOLD is mark-section-wisely, which is my command to mark the -;; section in a manner consistent with the major-mode. It -;; uses mark-defun for emacs-lisp, lisp, mark-c-function for C, -;; and mark-paragraph for other modes. -;; -;; -;; Some subtle differences are: -;; -;; APPEND is append-to-buffer. One doesn't append to the kill ring -;; much and SPECINS is now copy-to-killring; -;; REPLACE is replace-regexp; -;; FILL is fill-region-wisely, which uses indent-region for C, lisp -;; emacs-lisp, and fill-region for others. It asks if you -;; really want to fill-region in TeX-mode, because I find this -;; to be very dangerous. -;; CHNGCASE is case-flip for the character under the cursor only. -;; I felt that case-flip region is unlikely, as usually you -;; upcase-region or downcase region. Also, unlike EDT it -;; is independent of the direction you are going, as that -;; drives me nuts. -;; -;; I use Emacs definition of what a word is. This is considerably different -;; from what EDT thinks a word is. This is not good for dyed-in-the-wool EDT -;; fans, but is probably preferable for experienced Emacs users. My assumption -;; is that the former are a dying breed now that GNU Emacs has made it to VMS, -;; but let me know how you feel. Also, when you undelete a word it leave the -;; point at the end of the undeleted text, rather than the beginning. I might -;; change this as I'm not sure if I like this or not. I'm also not sure if I -;; want it to set the mark each time you delete a character or word. -;; -;; Backspace does not invoke beginning-of-line, because ^H is the help prefix, -;; and I felt it should be left as such. You can change this if you like. -;; -;; The ADVANCE and BACKUP keys do not work as terminators for forward or -;; backward searches. In Emacs, all search strings are terminated by return. -;; The searches will however go forward or backward depending on your current -;; direction. Also, when you change directions, the mode line will not be -;; updated immediately, but only when you next execute an emacs function. -;; Personally, I consider this to be a bug, not a feature. -;; -;; This should also work with VT-2xx's, though I haven't tested it extensively -;; on those terminals. It assumes that the CSI-map of vt_200.el has been -;; defined. -;; -;; There are also a whole bunch of GOLD letter, and GOLD character bindings: -;; look at edtdoc.el for them, or better still, look at the edt.el lisp code, -;; because after all, in the true Lisp tradition, the source code is *assumed* -;; to be self-documenting :-) -;; -;; Mike Clarkson, ...!allegra \ BITNET: mike@YUYETTI or -;; CRESS, York University, ...!decvax \ SYMALG@YUSOL -;; 4700 Keele Street, ...!ihnp4 > !utzoo!yetti!mike -;; North York, Ontario, ...!linus / -;; CANADA M3J 1P3. ...!watmath / Phone: +1 (416) 736-2100 x 7767 -;; -;; Note that I am not on ARPA, and must gateway any ARPA mail through BITNET or -;; UUCP.
