30 I. OVERVIEW:
31
32 This version of the EDT emulation package for GNU Emacs is a substantially
33 enhanced version of the original. A large part of the original can still be
34 found here, of course, but much of it has been modified and quite a bit is
35 new. Many of the ideas found here are borrowed from others. In particular,
36 some of the code found here was drawn from an earlier re-write of the EDT
37 package done at DSC in 1989 by Matthew Frohman.
38
39 Send bug fixes, suggestions for enhancements, and corrections to this
40 documentation to Kevin Gallagher (kgallagh@spd.dsccc.com).
41
42 The EDT emulation consists of the following files:
43
44 edt-user.doc - User instructions (which you are reading now)
45 edt.el - EDT Emulation Functions and Default Configuration
46 edt-lk201.el - Support for DEC LK-201 Keyboards
47 edt-vt100.el - Support for DEC VT-100 (and above) terminals
48 edt-mapper.el - Support for Keyboards used under X Windows
49 edt-pc.el - Support for the PC AT Keyboard under MS-DOS
50
51 Several goals were kept in mind when making this version:
52
53 1. Emulate EDT Keypad Mode commands closely so that current
54 EDT users will find that it easy and comfortable to use
55 GNU Emacs with a small learning curve;
56
57 2. Make it easy for a user to customize EDT emulation key
58 bindings without knowing much about Emacs Lisp;
59
60 3. Make it easy to switch between the original EDT default bindings
61 and the user's customized bindings, without having to exit Emacs.
62
63 4. Provide support for some TPU/EVE functions not supported in
64 EDT.
65
66 5. Provide an easy way to restore ALL original Emacs key bindings,
67 just as they existed before the EDT emulation was first invoked.
68
69 6. Support GNU Emacs 19. (Support for GNU Emacs 18 has been dropped.
70 Also, although there is some code designed to support Xemacs 19
71 (formerly Lucid Emacs), this is not fully implemented at this
72 time.
73
74 7. When running under X, support highlighting of marked text.
75
76 8. Handle terminal configuration under X interactively when the
77 emulation is invoked for the first time.
78
79 9. Support a PC AT keyboard under MS-DOS.
80
81 II. TERMINALS/KEYBOARDS SUPPORTED:
82
83 Keyboards used under X Windows are supported via the edt-mapper function. The
84 first time you invoke the emulation under X, the edt-mapper function is run
85 automatically and the user is prompted to identify which keys the emulation is
86 to use for the standard keypad and function keys EDT expects (e.g., PF1, PF2,
87 etc.). This configuration is saved to disk read each time the emulation is
88 invoked.
89
90 In character oriented connections not running a window manager, the following
91 terminals/keyboards are supported. (1) DEC VT-100 series and higher. This
92 includes well behaved VT clones and emulators. If you are using a VT series
93 terminal, be sure that the term environment variable is set properly before
94 invoking emacs. (2) PC AT keyboard under MS-DOS.
95
96 Be sure to read the SPECIAL NOTES FOR SOME PLATFORMS sections to see if those
97 notes apply to you.
98
99
100 III. STARTING THE EDT EMULATION:
101
102 Start up GNU Emacs and enter "M-x edt-emulation-on" to begin the emulation.
103 After initialization is complete, the following message will appear below the
104 status line informing you that the emulation has been enabled:
105
106 Default EDT keymap active
107
108 You can have the EDT Emulation start up automatically, each time you initiate
109 a GNU Emacs session, by adding the following line to your .emacs file:
110
111 (setq term-setup-hook 'edt-emulation-on)
112
113 A reference sheet is included (later on) listing the default EDT Emulation key
114 bindings. This sheet is also accessible on line from within Emacs by pressing
115 PF2, GOLD H, or HELP (when in the EDT Default Mode).
116
117 It is easy to customize key bindings in the EDT Emulation. (See CUSTOMIZING
118 section, below.) Customizations are placed in a file called edt-user.el. (A
119 sample edt-user.el file can be found in the CUSTOMIZING section.) If
120 edt-user.el is found in your GNU Emacs load path during EDT Emulation
121 initialization, then the following message will appear below the status line
122 indicating that the emulation has been enabled, enhanced by your own
123 customizations:
124
125 User EDT custom keymap active
126
127 Once enabled, it is easy to switch back and forth between your customized EDT
128 Emulation key bindings and the default EDT Emulation key bindings. It is also
129 easy to turn off the emulation. Doing so completely restores the original key
130 bindings in effect just prior to invoking the emulation.
131
132 Where EDT key bindings and GNU Emacs key bindings conflict, the default GNU
133 Emacs key bindings are retained by the EDT emulation by default. If you are a
134 diehard EDT user you may not like this. The CUSTOMIZING section explains how
135 to change this default.
136
137
138 IV. SPECIAL NOTES FOR SOME PLATFORMS:
139
140 Sun Workstations running X:
141
142 Some earlier Sun keyboards do not have arrow keys separate from the
143 keypad keys. It is difficult to emulate the full EDT keypad and still
144 retain use of the arrow keys on such keyboards.
145
146 The Sun Type 5 keyboard, however, does have separate arrow keys. This
147 makes it a candidate for setting up a reasonable EDT keypad emulation.
148 Unfortunately, Sun's default X keynames for the keypad keys don't permit
149 GNU Emacs to interpret the keypad 2, 4, 6, and 8 keys as something other
150 than arrow keys, nor use all the top row of keys for PF1 thru PF4 keys.
151 Here's the contents of an .xmodmaprc file which corrects this problem for
152 Sun Type 5 keyboards:
153
154 ! File: .xmodmaprc
155 !
156 ! Set up Sun Type 5 keypad for use with the GNU Emacs EDT Emulation
157 !
158 keycode 53 = KP_Divide
159 keycode 54 = KP_Multiply
160 keycode 57 = KP_Decimal
161 keycode 75 = KP_7
162 keycode 76 = KP_8
163 keycode 77 = KP_9
164 keycode 78 = KP_Subtract
165 keycode 97 = KP_Enter
166 keycode 98 = KP_4
167 keycode 99 = KP_5
168 keycode 100 = KP_6
169 keycode 101 = KP_0
170 keycode 105 = F24
171 keycode 119 = KP_1
172 keycode 120 = KP_2
173 keycode 121 = KP_3
174 keycode 132 = KP_Add
175
176 Feed .xmodmaprc to the xmodmap command and all the Sun Type 5 keypad keys
177 will now be configurable for the emulation of an LK-201 keypad (less the
178 comma key). The line
179
180 keycode 105 = F24
181
182 modifies the NumLock key to be the F24 key which can then be configured
183 to behave as the PF1 key. In doing so, you will no longer have a NumLock
184 key. If you are using other software under X which requires a NumLock
185 key, then examine your keyboard and look for one you don't use and
186 redefine it to be the NumLock key. (See the man page on xmodmap for for
187 further help on how to do this.)
188
189 PC users running MS-DOS:
190
191 By default, F1 is configured to emulate the PF1 (GOLD) key. But NumLock
192 can be used instead if you load a freeware TSR distributed with
193 MS-Kermit, call gold.com. It is distributed in a file called gold22.zip
194 and comes with the source code as well as a loadable binary image.
195 (See edt-pc.el for more information.)
196
197 PC users running Linux:
198
199 The default X server configuration of three keys PC AT keyboard keys
200 needs to be modified to permit the PC keyboard to emulate an LK-201
201 keyboard properly. Here's the contents of an .xmodmaprc file which makes
202 these changes for your:
203
204 ! File: .xmodmaprc
205 !
206 ! Set up PC keypad under Linux for the GNU Emacs EDT Emulation
207 !
208 keycode 22 = BackSpace
209 keycode 77 = F12
210 keycode 96 = Num_Lock
211
212 Feed the file to the xmodmap command and all the PC keypad keys will now
213 be configurable for the emulation of an LK-201 keypad (less the comma
214 key), the standard keyboard supplied with DEC terminals VT-200 and above.
215 This file switches the role of the F12 and NumLock keys. It also
216 modifies the definition of the Delete key above the arrow keys so that it
217 can be assigned a keybinding independently of the the BackSpace key.
218
219 NOTE: It is necessary to have NumLock ON for the PC keypad to emulate the
220 LK-201 keypad properly.
221
222
223 V. HOW DOES THIS EDT EMULATION DIFFER FROM REAL EDT?:
224
225 In general, you will find that this emulation of EDT replicates most, but not
226 all, of EDT's most used Keypad Mode editing functions and behavior. It is not
227 perfect, but most EDT users who have tried the emulation agree that it is
228 quite good enough to make it easy for die-hard EDT users to move over to using
229 GNU Emacs.
230
231 Here's a list of the most important differences between EDT and this GNU Emacs
232 EDT Emulation. The list is short but you must be aware of these differences
233 if you are to use the EDT Emulation effectively.
234
235 1. Entering repeat counts works a little differently than in EDT.
236
237 EDT allows users to enter a repeat count before entering a command that
238 accepts repeat counts. For example, when in EDT, pressing these three
239 keys in sequence, GOLD 5 KP1, will move the cursor in the current
240 direction 5 words.
241
242 Emacs provides two ways to enter repeat counts, though neither involves
243 using the GOLD key. In Emacs, repeat counts can be entered by using the
244 ESC key. For example, pressing these keys in sequence, ESC 1 0 KP1, will
245 move the cursor in the current direction 10 words.
246
247 Emacs provides another command called universal-argument that can do the
248 same thing, plus a few other things. Normally, Emacs has this bound to
249 C-u.
250
251 2. The EDT SUBS command, bound to GOLD ENTER, is NOT supported. The built-in
252 Emacs query-replace command has been bound to GOLD ENTER, instead. It is
253 much more convenient to use than SUBS.
254
255 3. EDT's line mode commands and nokeypad mode commands are NOT supported
256 (with one important exception; see item 8 in the Highlights section
257 below). Although, at first, this may seem like a big omission, the set of
258 built-in Emacs commands provides a much richer set of capabilities which
259 more than make up for this omission.
260
261 To enter Emacs commands not bound to keys, you can press GOLD KP7 or the
262 DO key. Emacs will display it's own command prompt called Meta-x (M-x).
263 You can also invoke this prompt the normal Emacs way by entering ESC x.
264
265 4. Selected text is highlighted ONLY when running under X Windows. Gnu Emacs
266 19 does not support highlighting of text on VT series terminals, at this
267 time.
268
269 5. Just like TPU/EVE, The ENTER key is NOT used to terminate input when the
270 editor prompts you for input. The RETURN key is used, instead. (KP4 and
271 KP5 do terminate input for the FIND command, just like in EDT, however.)
272
273
274
275
276 VI. SOME HIGHLIGHTS IN THIS EDT EMULATION, AND SOME COMPARISONS TO THE
277 ORIGINAL GNU EMACS EDT EMULATION:
278
279 1. The EDT define key command is supported (edt-define-key) and is bound to
280 C-k in the default EDT mode when EDT control sequence bindings are enabled
281 or one of the sample edt-user.el customization files is used. The TPU/EVE
282 learn command is supported but not bound to a key in the default EDT mode
283 but is bound in the sample edt-user.el files.
284
285 Unlike the TPU/EVE learn command, which uses one key to begin the learn
286 sequence, C-l, and another command to remember the sequence, C-r, this
287 version of the learn command (edt-learn) serves as a toggle to both begin
288 and to remember the learn sequence.
289
290 Many users who change the meaning of a key with the define key and the
291 learn commands, would like to be able to restore the original key binding
292 without having to quit and restart emacs. So a restore key command is
293 provided to do just that. When invoked, it prompts you to press the key
294 to which you wish the last replaced key definition restored. It is bound
295 to GOLD C-k in the default EDT mode when EDT control sequence bindings are
296 enabled or one of the sample edt-user.el customization files is used.
297
298 2. Direction support is fully supported. It is no longer accomplished by
299 re-defining keys each time the direction is changed. Thus, commands
300 sensitive to the current direction setting may be bound easily to any key.
301
302 3. All original emacs bindings are fully restored when EDT emulation is
303 turned off.
304
305 4. User custom EDT bindings are kept separate from the default EDT bindings.
306 One can toggle back and forth between the custom EDT bindings and default
307 EDT bindings.
308
309 5. The Emacs functions in edt.el attempt to emulate, where practical, the
310 exact behavior of the corresponding EDT keypad mode commands. In a few
311 cases, the emulation is not exact, but we hope you will agree it is close
312 enough. In a very few cases, we chose to use the Emacs way of handling
313 things. As mentioned earlier, we do not emulate the EDT SUBS command.
314 Instead, we chose to use the Emacs query-replace function, which we find
315 to be easier to use.
316
317 6. Emacs uses the regexp assigned to page-delimiter to determine what marks a
318 page break. This is normally "^\f", which causes the edt-page command to
319 ignore form feeds not located at the beginning of a line. To emulate the
320 EDT PAGE command exactly, page-delimiter is set to "\f" when EDT emulation
321 is turned on, and restored to "^\f" when EDT emulation is turned off.
322 But, since some users prefer the Emacs definition of a page break, or may
323 wish to preserve a customized definition of page break, one can override
324 the EDT definition by placing
325
326 (setq edt-keep-current-page-delimiter t)
327
328 in your .emacs file.
329
330 7. The EDT definition of a section of a terminal window is hardwired to be 16
331 lines of its one-and-only 24-line window (the EDT SECT command bound to
332 KP8). That's two-thirds of the window at a time. Since Emacs, like
333 TPU/EVE, can handle multiple windows of sizes of other than 24 lines, the
334 definition of section used here has been modified to two-thirds of the
335 current window. (There is also an edt-scroll-window function which you
336 may prefer over the SECT emulation.)
337
338 8. Cursor movement and deletion involving word entities is identical to EDT.
339 This, above all else, gives the die-hard EDT user a sense of being at
340 home. Also, an emulation of EDT's SET ENTITY WORD command is provided,
341 for those users who like to customize movement by a word at a time to
342 their own liking.
343
344 9. EDT's FIND and FNDNXT are supported.
345
346 10. EDT's APPEND and REPLACE commands are supported.
347
348 11. CHNGCASE is supported. It works on individual characters or selected
349 text, if SELECT is active. In addition, two new commands are provided:
350 edt-lowercase and edt-uppercase. They work on individual WORDS or
351 selected text, if SELECT is active.
352
353 12. Form feed and tab insert commands are supported.
354
355 13. A new command, edt-duplicate-word, is provided. If you experiment with
356 it, you might find it to be surprisingly useful and may wonder how you
357 ever got along without it! It is assigned to C-j in the sample
358 edt-user.el customization files.
359
360 14. TPU/EVE's Rectangular Cut and Paste functions (originally from the EVE-Plus
361 package) are supported. But unlike the TPU/EVE versions, these here
362 support both insert and overwrite modes. The seven rectangular functions
363 are bound to F7, F8, GOLD-F8, F9, GOLD-F9, F10, and GOLD-F10 in the
364 default EDT mode.
365
366 15. The original EDT emulation package set up many default regular and GOLD
367 bindings. We tried to preserve most (but not all!) of these, so users of
368 the original emulation package will feel more at home.
369
370 Nevertheless, there are still many GOLD key sequences which are not bound
371 to any functions. These are prime candidates to use for your own
372 customizations.
373
374 Also, there are several commands in edt.el not bound to any key. So, you
375 will find it worthwhile to look through edt.el for functions you may wish
376 to add to your personal customized bindings.
377
378 16. The VT200/VT300 series terminals steal the function keys F1 to F5 for
379 their own use. These do not generate signals which are sent to the host.
380 So, edt.el does not assign any default bindings to F1 through F5.
381
382 In addition, our VT220 terminals generate an interrupt when the F6 key is
383 pressed (^C or ^Y, can't remember which) and not the character sequence
384 documented in the manual. So, binding emacs commands to F6 will not work
385 if your terminal behaves the same way.
386
387 17. The VT220 terminal has no ESC, BS, nor LF keys, as does a VT100. So the
388 default EDT bindings adopt the standard DEC convention of having the F11,
389 F12, and F13 keys, on a VT200 series (and above) terminal, assigned to the
390 same EDT functions that are bound to ESC, BS, and LF on a VT100 terminal.
391
392 18. Each user, through the use of a private edt-user.el file, can customize,
393 very easily, personal EDT emulation bindings.
394
395 19. The EDT SELECT and RESET functions are supported. However, unlike EDT,
396 pressing RESET to cancel text selection does NOT reset the existing
397 setting of the current direction.
398
399 We also provide a TPU/EVE like version of the single SELECT/RESET
400 function, called edt-toggle-select, which makes the EDT SELECT function
401 into a toggle on/off switch. That is, if selection is ON, pressing SELECT
402 again turns selection off (cancels selection). This function is used in
403 the sample edt-user.el customization files.
404
405
406 VII. CUSTOMIZING:
407
408 Most EDT users, at one time or another, make some custom key bindings, or
409 use someone else's custom key bindings, which they come to depend upon just as
410 if they were built-in bindings. This EDT Emulation for GNU Emacs is designed
411 to make it easy to customize bindings.
412
413 If you wish to customize the EDT Emulation to use some of your own key
414 bindings, you need to make a private version of edt-user.el in your own
415 private lisp directory. There are two sample files edt-user.el1 and
416 edt-user.el2 for you to use as templates and for ideas. Look at
417 edt-user.el1 first. Unless you will be using two or more very different
418 types of terminals on the same system, you need not look at edt-user.el2.
419
420 First, you need to have your own private lisp directory, say ~/lisp, and
421 you should add it to the GNU Emacs load path.
422
423 NOTE: A few sites have different load-path requirements, so the above
424 directions may need some modification if your site has such special
425 needs.
426
427
428 Creating your own edt-user.el file:
429
430 A sample edt-user.el file is attached to the end of this user documentation.
431 You should use it as a guide to learn how you can customize EDT emulation
432 bindings to your own liking. Names used to identify the set of LK-201
433 keypad and function keys are:
434
435 Keypad Keys:
436 PF1 PF2 PF3 PF4
437 KP7 KP8 KP9 KP-
438 KP4 KP5 KP6 KP,
439 KP1 KP2 KP3
440 KP0 KPP KPE
441
442 Arrow Keys:
443 LEFT RIGHT DOWN UP
444
445 Function Keys:
446 F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F13 F14
447 HELP DO F17 F18 F19 F20
448
449 FIND INSERT REMOVE
450 SELECT PREVIOUS NEXT
451
452 Note:
453 Many VT-200 terminals, and above, steal function keys F1 thru
454 F5 for terminal setup control and don't send anything to the
455 host if pressed. So customizing bindings to these keys may
456 not work for you.
457
458 There are three basic functions that do the EDT emulation bindings:
459 edt-bind-standard-key, edt-bind-gold-key, and edt-bind-function-key.
460
461 The first two are for binding functions to keys which are standard across most
462 keyboards. This makes them keyboard independent, making it possible to define
463 these key bindings for all terminals in the file edt.el.
464
465 The first, edt-bind-standard-key, is used typically to bind emacs commands to
466 control keys, although some people use it to bind commands to other keys, as
467 well. (For example, some people use it to bind the VT200 seldom used
468 back-tick key (`) to the function "ESC-prefix" so it will behave like an ESC
469 key.) The second function, edt-bind-gold-key, is used to bind emacs commands
470 to gold key sequences involving alpha-numeric keys, special character keys,
471 and control keys.
472
473 The third function, edt-bind-function-key, is terminal dependent and is
474 defined in a terminal specific file (see edt-vt100.el for example). It is
475 used to bind emacs commands to function keys, to keypad keys, and to gold
476 sequences of those keys.
477
478 WARNING: Each of the three functions, edt-bind-function-key,
479 edt-bind-gold-key, and edt-bind-standard-key, has an optional
480 last argument. The optional argument should NOT be used in
481 edt-user.el! When the optional argument is missing, each
482 function knows to make the key binding part of the user's EDT
483 custom bindings, which is what you want to do in edt-user.el!
484
485 The EDT default bindings are set up in edt.el by calling these
486 same functions with the optional last argument set to "t". So, if
487 you decide to copy such function calls from edt.el to edt-user.el
488 for subsequent modification, BE SURE TO DELETE THE "t" AT THE END
489 OF EACH PARAMETER LIST!
490
491
492 SPECIFYING WORD ENTITIES:
493
494 The variable edt-word-entities is used to emulate EDT's SET ENTITY WORD
495 command. It contains a list of characters to be treated as words in
496 themselves. If the user does not define edt-word-entities in his/her .emacs
497 file, then it is set up with the EDT default containing only TAB.

499 The characters are stored in the list by their numerical values, not as
500 strings. Emacs supports several ways to specify the numerical value of a
501 character. One method is to use the question mark: ?A means the numerical
502 value for A, ?/ means the numerical value for /, and so on. Several
503 unprintable characters have special representations:
504
505 ?\b specifies BS, C-h
506 ?\t specifies TAB, C-i
507 ?\n specifies LFD, C-j
508 ?\v specifies VTAB, C-k
509 ?\f specifies FF, C-l
510 ?\r specifies CR, C-m
511 ?\e specifies ESC, C-[
512 ?\\ specifies \
513
514 Here are some examples:
515
516 (setq edt-word-entities '(?\t ?- ?/)) ;; Specifies TAB, - , and /
517 (setq edt-word-entities '(?\t) ;; Specifies TAB, the default
518
519 You can also specify characters by their decimal ascii values:
520
521 (setq edt-word-entities '(9 45 47)) ;; Specifies TAB, - , and /
522

524 ENABLING EDT CONTROL KEY SEQUENCE BINDINGS:
525
526 Where EDT key bindings and GNU Emacs key bindings conflict, the default GNU
527 Emacs key bindings are retained by default. Some diehard EDT users may not
528 like this. So, if the variable edt-use-EDT-control-key-bindings is set to
529 true in a user's .emacs file, then the default EDT Emulation mode will enable
530 most of the original EDT control key sequence bindings. If you wish to do
531 this, add the following line to your .emacs file:
532
533 (setq edt-use-EDT-control-key-bindings t)

625 ;;; Commentary:
626
627 ;; This file contains GNU Emacs User Custom EDT bindings and functions. In
628 ;; this example file, there is no special test for the type of terminal being
629 ;; used. The assumption is that all key bindings here apply to all terminals
630 ;; that may be used. (In fact, it was written by an individual who uses only
631 ;; VT series terminals when logging into a VAX.)
632 ;;
633 ;; WARNING: Each of the three functions, edt-bind-function-key,
634 ;; edt-bind-gold-key, and edt-bind-standard-key, has an optional
635 ;; last argument. The optional argument should NOT be used in
636 ;; edt-user.el! When the optional argument is missing, each
637 ;; function knows to make the key binding part of the user's EDT
638 ;; custom bindings, which is what you want to do in edt-user.el!
639 ;;
640 ;; The EDT default bindings are set up in edt.el by calling these
641 ;; same functions with the optional last argument set to "t". So, if
642 ;; you decide to copy such function calls from edt.el to edt-user.el
643 ;; for subsequent modification, BE SURE TO DELETE THE "t" AT THE END
644 ;; OF EACH PARAMETER LIST!
645 ;;
646
647 ;;; Usage:
648
649 ;; See edt-user.doc in the emacs etc directory.
