27 | I. OVERVIEW: | |
28 | ||
4f6e7915 GM |
29 | This is Version 4.0 of the EDT Emulation for Emacs 19 and above. |
30 | It comes with special functions which replicate nearly all of EDT's | |
31 | keypad mode behavior. It sets up default keypad and function key | |
32 | bindings which closely match those found in EDT. Support is | |
33 | provided so that users may reconfigure most keypad and function key | |
34 | bindings to their own liking. | |
35 | ||
36 | NOTE: Version 4.0 contains several enhancements. See the | |
37 | Enhancements section below for the details. | |
38 | ||
39 | ||
40 | Quick Start: | |
41 | ||
42 | To start the EDT Emulation, first start Emacs and then enter | |
43 | ||
44 | M-x edt-emulation-on | |
a933dad1 | 45 | |
4f6e7915 GM |
46 | to begin the emulation. After initialization is complete, the |
47 | following message will appear below the status line informing you | |
48 | that the emulation has been enabled: "Default EDT keymap active". | |
49 | ||
50 | You can have the EDT Emulation start up automatically, each time | |
51 | you initiate a GNU Emacs session, by adding the following line to | |
52 | your .emacs file: | |
53 | ||
54 | (add-hook term-setup-hook 'edt-emulation-on) | |
55 | ||
56 | IMPORTANT: Be sure to read the rest of this file. It contains very | |
57 | useful information on how the EDT Emulation behaves and how | |
58 | to customize it to your liking. | |
a933dad1 DL |
59 | |
60 | The EDT emulation consists of the following files: | |
61 | ||
4f6e7915 GM |
62 | edt-user.doc - User Instructions and Sample Customization File |
63 | edt.el - EDT Emulation Functions and Default Configuration | |
64 | edt-lk201.el - Built-in support for DEC LK-201 Keyboards | |
65 | edt-vt100.el - Built-in support for DEC VT-100 (and above) terminals | |
66 | edt-pc.el - Built-in support for PC 101 Keyboards under MS-DOS | |
67 | edt-mapper.el - Create an EDT LK-201 Map File for Keyboards Without | |
68 | Built-in Support | |
69 | ||
70 | Enhancements: | |
71 | ||
72 | Version 4.0 contains the following enhancements: | |
73 | ||
74 | 1. Scroll margins at the top and bottom of the window are now | |
75 | supported. (The design was copied from tpu-extras.el.) By | |
76 | default, this feature is enabled with the top margin set to | |
77 | 10% of the window and the bottom margin set to 15% of the | |
78 | window. To change these settings, you can invoke the function | |
79 | edt-set-scroll-margins in your .emacs file. For example, the | |
80 | following line | |
81 | ||
82 | (edt-set-scroll-margins "20%" "25%") | |
83 | ||
84 | sets the top margin to 20% of the window and the bottom margin | |
85 | to 25% of the window. To disable this feature, set each | |
86 | margin to 0%. You can also invoke edt-set-scroll-margins | |
87 | interactively while EDT Emulation is active to change the | |
88 | settings for that session. | |
89 | ||
90 | NOTE: Another way to set the scroll margins is to use the | |
91 | Emacs customization feature (not available in Emacs 19) to set | |
92 | the following two variables directly: | |
93 | ||
94 | edt-top-scroll-margin and edt-bottom-scroll-margin | |
95 | ||
96 | Enter the Emacs `customize' command. First select the Editing | |
97 | group and then select the Emulations group. Finally, select | |
98 | the Edt group and follow the directions. | |
99 | ||
100 | 2. The SUBS command is now supported and bound to GOLD-Enter by | |
101 | default. (This design was copied from tpu-edt.el.) Note, in | |
102 | earlier versions of EDT Emulation, GOLD-Enter was assigned to | |
103 | the Emacs function `query-replace'. The binding of | |
104 | `query-replace' has been moved to GOLD-/. If you prefer to | |
105 | restore `query-replace' to GOLD-Enter, then use an EDT user | |
106 | customization file, edt-user.el, to do this. See edt-user.doc | |
107 | for details. | |
108 | ||
109 | 3. EDT Emulation now also works in XEmacs, including the | |
110 | highlighting of selected text. | |
111 | ||
112 | 4. If you access a workstation using an X Server, observe that | |
113 | the initialization file generated by edt-mapper.el will now | |
114 | contain the name of the X Server vendor. This is a | |
115 | convenience for those who have access to their Unix account | |
116 | from more than one type of X Server. Since different X | |
117 | Servers typically require different EDT emulation | |
118 | initialization files, edt-mapper.el will now generate these | |
119 | different initialization files and save them with different | |
120 | names. Then, the correct initialization file for the | |
121 | particular X server in use is loaded correctly automatically. | |
122 | ||
123 | 5. Also, edt-mapper.el is now capable of binding an ASCII key | |
124 | sequence, providing the ASCII key sequence prefix is already | |
125 | known by Emacs to be a prefix. As a result of providing this | |
126 | support, some terminal/keyboard/window system configurations, | |
127 | which don't have a complete set of sensible function key | |
128 | bindings built into Emacs in `function-key-map', can still be | |
129 | configured for use with EDT Emulation. (Note: In a few rare | |
130 | circumstances this does not work properly. In particular, it | |
131 | does not work if a subset of the leading ASCII characters in a | |
132 | key sequence are recognized by Emacs as having an existing | |
133 | binding. For example, if the keypad 7 (KP-7) key generates | |
134 | the sequence \"<ESC>Ow\" and \"<ESC>O\" is already bound to a | |
135 | function, pressing KP-7 when told to do so by edt-mapper.el | |
136 | will result in edt-mapper.el incorrectly mapping \"<ESC>O\" to | |
137 | KP-7 and \"w\" to KP-8. If something like this happens to | |
138 | you, it is probably a bug in the support for your keyboard | |
139 | within Emacs OR a bug in the Unix termcap/terminfo support for | |
140 | your terminal OR a bug in the terminal emulation software you | |
141 | are using.) | |
142 | ||
143 | 6. The edt-quit function (bound to GOLD-q by default) has been | |
144 | modified to warn the user when file-related buffer | |
145 | modifications exist. It now cautions the user that those | |
146 | modifications will be lost if the user quits without saving | |
147 | those buffers. | |
148 | ||
149 | ||
150 | Goals: | |
151 | ||
152 | 1. Emulate EDT Keypad Mode commands closely so that current EDT users | |
153 | will find that it easy and comfortable to use GNU Emacs with a | |
154 | small learning curve; | |
a933dad1 | 155 | |
4f6e7915 GM |
156 | 2. Make it easy for a user to customize EDT emulation key bindings |
157 | without knowing much about Emacs Lisp; | |
a933dad1 DL |
158 | |
159 | 3. Make it easy to switch between the original EDT default bindings | |
4f6e7915 GM |
160 | and the user's customized EDT bindings, without having to exit |
161 | Emacs. | |
a933dad1 | 162 | |
4f6e7915 | 163 | 4. Provide support for some TPU/EVE functions not supported in EDT. |
a933dad1 DL |
164 | |
165 | 5. Provide an easy way to restore ALL original Emacs key bindings, | |
166 | just as they existed before the EDT emulation was first invoked. | |
167 | ||
4f6e7915 GM |
168 | 6. Support GNU Emacs 19 and higher. (GNU Emacs 18 and below is no |
169 | longer supported.) XEmacs 19, and above, is also supported. | |
a933dad1 | 170 | |
4f6e7915 GM |
171 | 7. Supports highlighting of marked text within the EDT emulation on |
172 | all platforms on which Emacs supports highlighting of marked text. | |
a933dad1 | 173 | |
4f6e7915 GM |
174 | 8. Handle terminal configuration interactively for most terminal |
175 | configurations, when the emulation is invoked for the first time. | |
a933dad1 DL |
176 | |
177 | 9. Support a PC AT keyboard under MS-DOS. | |
4f6e7915 | 178 | |
a933dad1 DL |
179 | \f |
180 | II. TERMINALS/KEYBOARDS SUPPORTED: | |
181 | ||
4f6e7915 GM |
182 | Keyboards used under a Window System are supported via the edt-mapper function. |
183 | The first time you invoke the emulation under a window system, the edt-mapper | |
184 | function is run automatically and the user is prompted to identify which keys | |
185 | the emulation is to use for the standard keypad and function keys EDT expects | |
186 | (e.g., PF1, PF2, KP0, KP1, F1, F2, etc.). This configuration is saved to disk | |
187 | read each time the emulation is invoked. | |
188 | ||
189 | In character oriented connections not running a window manager, built-in | |
190 | support for the following terminals/keyboards is provided: | |
a933dad1 | 191 | |
4f6e7915 GM |
192 | (1) DEC VT-100 series and higher. This includes well behaved VT clones and |
193 | emulators. If you are using a VT series terminal, be sure that the term | |
194 | environment variable is set properly before invoking emacs. | |
195 | ||
196 | (2) PC AT keyboard under MS-DOS. | |
a933dad1 DL |
197 | |
198 | Be sure to read the SPECIAL NOTES FOR SOME PLATFORMS sections to see if those | |
199 | notes apply to you. | |
200 | ||
201 | \f | |
202 | III. STARTING THE EDT EMULATION: | |
203 | ||
204 | Start up GNU Emacs and enter "M-x edt-emulation-on" to begin the emulation. | |
205 | After initialization is complete, the following message will appear below the | |
206 | status line informing you that the emulation has been enabled: | |
207 | ||
208 | Default EDT keymap active | |
209 | ||
210 | You can have the EDT Emulation start up automatically, each time you initiate | |
211 | a GNU Emacs session, by adding the following line to your .emacs file: | |
212 | ||
4f6e7915 | 213 | (add-hook term-setup-hook 'edt-emulation-on) |
a933dad1 DL |
214 | |
215 | A reference sheet is included (later on) listing the default EDT Emulation key | |
216 | bindings. This sheet is also accessible on line from within Emacs by pressing | |
217 | PF2, GOLD H, or HELP (when in the EDT Default Mode). | |
218 | ||
219 | It is easy to customize key bindings in the EDT Emulation. (See CUSTOMIZING | |
220 | section, below.) Customizations are placed in a file called edt-user.el. (A | |
221 | sample edt-user.el file can be found in the CUSTOMIZING section.) If | |
222 | edt-user.el is found in your GNU Emacs load path during EDT Emulation | |
223 | initialization, then the following message will appear below the status line | |
224 | indicating that the emulation has been enabled, enhanced by your own | |
225 | customizations: | |
226 | ||
227 | User EDT custom keymap active | |
228 | ||
229 | Once enabled, it is easy to switch back and forth between your customized EDT | |
4f6e7915 GM |
230 | Emulation key bindings and the default EDT Emulation key bindings. (See the |
231 | sample edt-user.el file below. Look at the binding to GOLD Z.) It is also | |
232 | easy to turn off the emulation (via the command edt-emulation-off). Doing so | |
233 | completely restores the original key bindings in effect just prior to invoking | |
234 | the emulation. | |
235 | ||
236 | Emacs binds keys to ASCII control characters and so does the real EDT. Where | |
237 | EDT key bindings and GNU Emacs key bindings conflict, the default GNU Emacs key | |
238 | bindings are retained by the EDT emulation by default. If you are a diehard | |
239 | EDT user you may not like this. The CUSTOMIZING section explains how to change | |
240 | this so that the EDT bindings to ASCII control characters override the default | |
241 | Emacs bindings. | |
a933dad1 DL |
242 | |
243 | \f | |
244 | IV. SPECIAL NOTES FOR SOME PLATFORMS: | |
245 | ||
246 | Sun Workstations running X: | |
247 | ||
4f6e7915 GM |
248 | Some earlier Sun keyboards do not have arrow keys separate from the keypad |
249 | keys. It is difficult to emulate the full EDT keypad and still retain use | |
250 | of the arrow keys on such keyboards. | |
251 | ||
252 | The Sun Type 5 and other more recent Sun keyboards, however, do have | |
253 | separate arrow keys. This makes them candidates for setting up a | |
254 | reasonable EDT keypad emulation. | |
a933dad1 | 255 | |
4f6e7915 GM |
256 | Depending upon the configuration of the version of X installed on your |
257 | system, you may find the default X keynames for the keypad keys don't | |
258 | permit Emacs to interpret some or all the keypad keys as something other | |
259 | than arrow keys, numeric keys, Home, PgUP, etc. Both Sun and HP have been | |
260 | particularly guilty of making bizarre keysym assignments to the keypad | |
261 | keys. | |
262 | ||
263 | In most cases, the X Windows command, xmodmap, can be used to correct the | |
264 | problem. Here's a sample .xmodmaprc file which corrects this problem on | |
265 | one Sun workstation configuration using an older SunOS release configured | |
266 | with a Sun Type 5 keyboard: | |
a933dad1 DL |
267 | |
268 | ! File: .xmodmaprc | |
269 | ! | |
270 | ! Set up Sun Type 5 keypad for use with the GNU Emacs EDT Emulation | |
271 | ! | |
272 | keycode 53 = KP_Divide | |
273 | keycode 54 = KP_Multiply | |
274 | keycode 57 = KP_Decimal | |
275 | keycode 75 = KP_7 | |
276 | keycode 76 = KP_8 | |
277 | keycode 77 = KP_9 | |
278 | keycode 78 = KP_Subtract | |
279 | keycode 97 = KP_Enter | |
280 | keycode 98 = KP_4 | |
281 | keycode 99 = KP_5 | |
282 | keycode 100 = KP_6 | |
283 | keycode 101 = KP_0 | |
284 | keycode 105 = F24 | |
285 | keycode 119 = KP_1 | |
286 | keycode 120 = KP_2 | |
287 | keycode 121 = KP_3 | |
288 | keycode 132 = KP_Add | |
289 | ||
4f6e7915 GM |
290 | If edt-mapper.el does not recognize your keypad keys as unique keys, use |
291 | the command | |
292 | ||
293 | xmodmap -pke | |
294 | ||
295 | to get a listing of the actual key codes and the keysyms mapped to them | |
296 | and then generate you own custom .xmodmaprc similar to the one above. | |
297 | ||
298 | Next, feed .xmodmaprc to the xmodmap command and all the Sun Type 5 keypad | |
299 | keys will now be configurable for the emulation of an LK-201 keypad (less | |
300 | the comma key). In this example, the line | |
a933dad1 DL |
301 | |
302 | keycode 105 = F24 | |
303 | ||
4f6e7915 GM |
304 | changes the X Windows name of the keypad NumLock key to be known |
305 | internally as the F24 key. Doing so permits it to be configured to behave | |
306 | as the PF1 (Gold) key. | |
307 | ||
308 | The side effect of this change is that you will no longer have a NumLock | |
309 | key. If you are using other software under X which requires a NumLock | |
310 | key, then examine your keyboard and look for one you don't use and | |
311 | redefine it to be the NumLock key. Basically, you need to clear the | |
312 | NumLock key from being assigned as a modifier, assign it to the key of | |
313 | your choice, and then add it back as a modifier. (See the "General Notes | |
314 | on Using NumLock for the PF1 Key on a Unix System" section below for | |
315 | further help on how to do this.) | |
a933dad1 DL |
316 | |
317 | PC users running MS-DOS: | |
318 | ||
319 | By default, F1 is configured to emulate the PF1 (GOLD) key. But NumLock | |
4f6e7915 GM |
320 | can be used instead if you load a freeware TSR distributed with MS-Kermit, |
321 | call gold.com. This was once distributed in a file called gold22.zip and | |
322 | came with the source code as well as a loadable binary image. (See | |
323 | edt-pc.el in the Emacs lisp/emulation directory for more information.) | |
a933dad1 DL |
324 | |
325 | PC users running GNU/Linux: | |
326 | ||
4f6e7915 GM |
327 | The default X server configuration varies from distribution to |
328 | distribution and release to release of GNU/Linux. If your system fails to | |
329 | recognize the keypad keys as distinct keys, change the NumLock state, | |
330 | turning it on or off, as the case may be, then try again. If this doesn't | |
331 | solve your problem, you may have to modify the X keysym mappings with | |
332 | xmodmap. | |
333 | ||
334 | On one distribution on an Intel PC, the following .xmodmaprc set things up | |
335 | nicely. | |
a933dad1 DL |
336 | |
337 | ! File: .xmodmaprc | |
338 | ! | |
339 | ! Set up PC keypad under GNU/Linux for the GNU Emacs EDT Emulation | |
340 | ! | |
341 | clear mod2 | |
342 | keycode 77 = F12 | |
343 | keycode 96 = Num_Lock Pointer_EnableKeys | |
344 | add mod2 = Num_Lock | |
345 | ||
4f6e7915 GM |
346 | In this example, after feeding the file to the xmodmap command, the PC |
347 | NumLock keypad key will be configurable for the emulation of the PF1 key. | |
348 | The PC keypad can now emulate an LK-201 keypad (less the comma key), the | |
349 | standard keyboard supplied with DEC terminals VT-200 and above. This | |
350 | .xmodmaprc file switches the role of the F12 and NumLock keys. It has | |
351 | been tested on RedHat GNU/Linux 5.2. Other versions of GNU/Linux may | |
352 | require different keycodes. (See the "General Notes on Using NumLock for | |
353 | the PF1 Key on a Unix System" section below for further help on how to do | |
354 | this.) | |
355 | ||
356 | NOTE: Remember, it may be necessary to have NumLock in one position (ON) | |
357 | or the other (OFF) for the PC keypad to emulate the LK-201 keypad | |
358 | properly. | |
a933dad1 DL |
359 | \f |
360 | General Notes on Using NumLock for the PF1 Key on a Unix System: | |
361 | ||
362 | Making the physical NumLock key available for use in the EDT | |
363 | Emulation requires some modification to the default X Window | |
364 | settings. Since the keycode assignments vary from system to | |
365 | system, some investigation is needed to see how to do this on | |
366 | a particular system. | |
367 | ||
4f6e7915 GM |
368 | You will need to look at the output generated by xmodmap invoked with the |
369 | "-pm" switch. examined. For example, on RedHat GNU/Linux 5.2 on a PC, we | |
370 | get the following output when running xmodmap. | |
a933dad1 DL |
371 | |
372 | "xmodmap -pm" yields: | |
373 | ||
374 | xmodmap: up to 2 keys per modifier, (keycodes in parentheses): | |
375 | ||
376 | shift Shift_L (0x32), Shift_R (0x3e) | |
377 | lock Caps_Lock (0x42) | |
378 | control Control_L (0x25), Control_R (0x6d) | |
379 | mod1 Alt_L (0x40), Alt_R (0x71) | |
380 | mod2 Num_Lock (0x4d) | |
381 | mod3 | |
382 | mod4 | |
383 | mod5 Scroll_Lock (0x4e) | |
384 | ||
385 | ||
386 | Note that Num_Lock is assigned to the modifier mod2. This is | |
387 | what hides Num_Lock from being seen by Emacs. | |
388 | ||
389 | Now, "xmodmap -pke" yields: | |
390 | ||
391 | . | |
392 | . | |
393 | . | |
394 | keycode 77 = Num_Lock Pointer_EnableKeys | |
395 | . | |
396 | . | |
397 | . | |
398 | keycode 96 = F12 | |
399 | . | |
400 | . | |
401 | . | |
402 | ||
403 | So, in RedHat GNU/Linux 5.2 on a PC, Num_Lock generates keycode | |
404 | 77. The following steps are taken: | |
405 | ||
406 | 1. clear the assignment of Num_Lock to mod2; | |
407 | 2. swap the keycodes assigned to F12 and Num_Lock; | |
408 | 3. assign Num_Lock back to mod2. | |
409 | ||
410 | The .xmodmaprc file looks like this: | |
411 | ||
412 | ! File: .xmodmaprc | |
413 | ! | |
414 | ! Set up PC keypad under GNU/Linux for the GNU Emacs EDT Emulation | |
415 | ! | |
416 | clear mod2 | |
417 | keycode 77 = F12 | |
418 | keycode 96 = Num_Lock Pointer_EnableKeys | |
419 | add mod2 = Num_Lock | |
420 | ||
421 | So, after executing "xmodmap .xmodmaprc", a press of the physical | |
422 | F12 key looks like a Num_Lock keypress to X. Also, a press of the | |
423 | physical NumLock key looks like a press of the F12 key to X. | |
424 | ||
425 | Now, edt-mapper.el will see "f12" when the physical NumLock key | |
426 | is pressed, allowing the NumLock key to be used as the EDT PF1 | |
427 | (Gold) key. | |
428 | \f | |
429 | V. HOW DOES THIS EDT EMULATION DIFFER FROM REAL EDT?: | |
430 | ||
431 | In general, you will find that this emulation of EDT replicates most, but not | |
432 | all, of EDT's most used Keypad Mode editing functions and behavior. It is not | |
433 | perfect, but most EDT users who have tried the emulation agree that it is | |
434 | quite good enough to make it easy for die-hard EDT users to move over to using | |
435 | GNU Emacs. | |
436 | ||
437 | Here's a list of the most important differences between EDT and this GNU Emacs | |
438 | EDT Emulation. The list is short but you must be aware of these differences | |
439 | if you are to use the EDT Emulation effectively. | |
440 | ||
441 | 1. Entering repeat counts works a little differently than in EDT. | |
442 | ||
443 | EDT allows users to enter a repeat count before entering a command that | |
4f6e7915 GM |
444 | accepts repeat counts. For example, when using the real EDT, pressing |
445 | these three keys in sequence, GOLD 5 KP1, will move the cursor in the | |
446 | current direction 5 words. This does NOT work in Emacs! | |
a933dad1 | 447 | |
4f6e7915 GM |
448 | Emacs provides two ways to enter repeat counts and neither involves using |
449 | the GOLD key. First, repeat counts can be entered in Emacs by using the | |
a933dad1 | 450 | ESC key. For example, pressing these keys in sequence, ESC 1 0 KP1, will |
4f6e7915 GM |
451 | move the cursor in the current direction 10 words. Second, Emacs provides |
452 | another command called universal-argument that can be used to do the same | |
453 | thing. Normally, in Emacs has this bound to C-u. | |
a933dad1 | 454 | |
4f6e7915 | 455 | 2. EDT's line mode commands and nokeypad mode commands are NOT supported |
a933dad1 DL |
456 | (with one important exception; see item 8 in the Highlights section |
457 | below). Although, at first, this may seem like a big omission, the set of | |
458 | built-in Emacs commands provides a much richer set of capabilities which | |
459 | more than make up for this omission. | |
460 | ||
4f6e7915 GM |
461 | To enter Emacs commands not bound to keys, you can press GOLD KP7 or the DO |
462 | key. Emacs will display its own command prompt "M-x". This stands for the | |
463 | keypress Meta-x, where Meta is a special shift key. The Alt key is often | |
464 | mapped to behave as a Meta key. So, you can also invoke this prompt by | |
465 | pressing Meta-x. Typing the sequence "ESC x" will also invoke the prompt. | |
a933dad1 | 466 | |
4f6e7915 GM |
467 | 3. Selected text is highlighted ONLY on systems where Emacs supports the |
468 | highlighting of text. | |
a933dad1 | 469 | |
4f6e7915 | 470 | 4. Just like in TPU/EVE, the ENTER key is NOT used to terminate input when the |
a933dad1 | 471 | editor prompts you for input. The RETURN key is used, instead. (KP4 and |
4f6e7915 GM |
472 | KP5 (the direction keys) do terminate input for the FIND command, just like |
473 | in EDT, however.) | |
a933dad1 DL |
474 | |
475 | ||
476 | \f | |
477 | ||
478 | VI. SOME HIGHLIGHTS IN THIS EDT EMULATION, AND SOME COMPARISONS TO THE | |
479 | ORIGINAL GNU EMACS EDT EMULATION: | |
480 | ||
481 | 1. The EDT define key command is supported (edt-define-key) and is bound to | |
482 | C-k in the default EDT mode when EDT control sequence bindings are enabled | |
483 | or one of the sample edt-user.el customization files is used. The TPU/EVE | |
484 | learn command is supported but not bound to a key in the default EDT mode | |
4f6e7915 | 485 | but is bound in the sample edt-user.el file. |
a933dad1 DL |
486 | |
487 | Unlike the TPU/EVE learn command, which uses one key to begin the learn | |
488 | sequence, C-l, and another command to remember the sequence, C-r, this | |
489 | version of the learn command (edt-learn) serves as a toggle to both begin | |
490 | and to remember the learn sequence. | |
491 | ||
492 | Many users who change the meaning of a key with the define key and the | |
493 | learn commands, would like to be able to restore the original key binding | |
494 | without having to quit and restart emacs. So a restore key command is | |
495 | provided to do just that. When invoked, it prompts you to press the key | |
496 | to which you wish the last replaced key definition restored. It is bound | |
497 | to GOLD C-k in the default EDT mode when EDT control sequence bindings are | |
498 | enabled or one of the sample edt-user.el customization files is used. | |
499 | ||
4f6e7915 | 500 | 2. Direction support is fully supported. |
a933dad1 | 501 | |
4f6e7915 GM |
502 | 3. All original Emacs bindings are fully restored when EDT emulation is turned |
503 | off. So, if a fellow worker comes over to your terminal to help you with a | |
504 | software problem, for example, and is completely confused by your EDT | |
505 | emulation bindings, just enter the command, edt-emulation-off, at the M-x | |
506 | prompt and the original Emacs bindings will be restored. To resume the EDT | |
507 | emulation, just enter edt-emulation-on. | |
a933dad1 DL |
508 | |
509 | 4. User custom EDT bindings are kept separate from the default EDT bindings. | |
510 | One can toggle back and forth between the custom EDT bindings and default | |
511 | EDT bindings. | |
512 | ||
513 | 5. The Emacs functions in edt.el attempt to emulate, where practical, the | |
514 | exact behavior of the corresponding EDT keypad mode commands. In a few | |
515 | cases, the emulation is not exact, but we hope you will agree it is close | |
516 | enough. In a very few cases, we chose to use the Emacs way of handling | |
517 | things. As mentioned earlier, we do not emulate the EDT SUBS command. | |
518 | Instead, we chose to use the Emacs query-replace function, which we find | |
519 | to be easier to use. | |
520 | ||
521 | 6. Emacs uses the regexp assigned to page-delimiter to determine what marks a | |
522 | page break. This is normally "^\f", which causes the edt-page command to | |
523 | ignore form feeds not located at the beginning of a line. To emulate the | |
524 | EDT PAGE command exactly, page-delimiter is set to "\f" when EDT emulation | |
525 | is turned on, and restored to "^\f" when EDT emulation is turned off. | |
526 | But, since some users prefer the Emacs definition of a page break, or may | |
527 | wish to preserve a customized definition of page break, one can override | |
528 | the EDT definition by placing | |
529 | ||
530 | (setq edt-keep-current-page-delimiter t) | |
531 | ||
4f6e7915 GM |
532 | in your .emacs file. Or, you can used the Emacs customize command |
533 | to change its setting. | |
a933dad1 DL |
534 | |
535 | 7. The EDT definition of a section of a terminal window is hardwired to be 16 | |
536 | lines of its one-and-only 24-line window (the EDT SECT command bound to | |
537 | KP8). That's two-thirds of the window at a time. Since Emacs, like | |
538 | TPU/EVE, can handle multiple windows of sizes of other than 24 lines, the | |
539 | definition of section used here has been modified to two-thirds of the | |
540 | current window. (There is also an edt-scroll-window function which you | |
541 | may prefer over the SECT emulation.) | |
542 | ||
543 | 8. Cursor movement and deletion involving word entities is identical to EDT. | |
544 | This, above all else, gives the die-hard EDT user a sense of being at | |
545 | home. Also, an emulation of EDT's SET ENTITY WORD command is provided, | |
546 | for those users who like to customize movement by a word at a time to | |
547 | their own liking. | |
548 | ||
549 | 9. EDT's FIND and FNDNXT are supported. | |
550 | ||
4f6e7915 | 551 | 10. EDT's APPEND, REPLACE, and SUBS commands are supported. |
a933dad1 DL |
552 | |
553 | 11. CHNGCASE is supported. It works on individual characters or selected | |
554 | text, if SELECT is active. In addition, two new commands are provided: | |
555 | edt-lowercase and edt-uppercase. They work on individual WORDS or | |
556 | selected text, if SELECT is active. | |
557 | ||
558 | 12. Form feed and tab insert commands are supported. | |
559 | ||
560 | 13. A new command, edt-duplicate-word, is provided. If you experiment with | |
561 | it, you might find it to be surprisingly useful and may wonder how you | |
562 | ever got along without it! It is assigned to C-j in the sample | |
563 | edt-user.el customization files. | |
564 | ||
565 | 14. TPU/EVE's Rectangular Cut and Paste functions (originally from the EVE-Plus | |
566 | package) are supported. But unlike the TPU/EVE versions, these here | |
567 | support both insert and overwrite modes. The seven rectangular functions | |
568 | are bound to F7, F8, GOLD-F8, F9, GOLD-F9, F10, and GOLD-F10 in the | |
569 | default EDT mode. | |
570 | ||
571 | 15. The original EDT emulation package set up many default regular and GOLD | |
572 | bindings. We tried to preserve most (but not all!) of these, so users of | |
573 | the original emulation package will feel more at home. | |
574 | ||
575 | Nevertheless, there are still many GOLD key sequences which are not bound | |
576 | to any functions. These are prime candidates to use for your own | |
577 | customizations. | |
578 | ||
579 | Also, there are several commands in edt.el not bound to any key. So, you | |
580 | will find it worthwhile to look through edt.el for functions you may wish | |
581 | to add to your personal customized bindings. | |
582 | ||
583 | 16. The VT200/VT300 series terminals steal the function keys F1 to F5 for | |
584 | their own use. These do not generate signals which are sent to the host. | |
585 | So, edt.el does not assign any default bindings to F1 through F5. | |
586 | ||
587 | In addition, our VT220 terminals generate an interrupt when the F6 key is | |
588 | pressed (^C or ^Y, can't remember which) and not the character sequence | |
589 | documented in the manual. So, binding emacs commands to F6 will not work | |
590 | if your terminal behaves the same way. | |
591 | ||
592 | 17. The VT220 terminal has no ESC, BS, nor LF keys, as does a VT100. So the | |
593 | default EDT bindings adopt the standard DEC convention of having the F11, | |
594 | F12, and F13 keys, on a VT200 series (and above) terminal, assigned to the | |
595 | same EDT functions that are bound to ESC, BS, and LF on a VT100 terminal. | |
596 | ||
597 | 18. Each user, through the use of a private edt-user.el file, can customize, | |
598 | very easily, personal EDT emulation bindings. | |
599 | ||
600 | 19. The EDT SELECT and RESET functions are supported. However, unlike EDT, | |
601 | pressing RESET to cancel text selection does NOT reset the existing | |
602 | setting of the current direction. | |
603 | ||
604 | We also provide a TPU/EVE like version of the single SELECT/RESET | |
605 | function, called edt-toggle-select, which makes the EDT SELECT function | |
606 | into a toggle on/off switch. That is, if selection is ON, pressing SELECT | |
607 | again turns selection off (cancels selection). This function is used in | |
608 | the sample edt-user.el customization files. | |
4f6e7915 GM |
609 | |
610 | 20. EDT scroll margins are supported, but are disabled by default. (See | |
611 | CUSTOMIZING section below for instructions on how to enable them.) | |
a933dad1 DL |
612 | \f |
613 | ||
614 | VII. CUSTOMIZING: | |
615 | ||
616 | Most EDT users, at one time or another, make some custom key bindings, or | |
617 | use someone else's custom key bindings, which they come to depend upon just as | |
618 | if they were built-in bindings. This EDT Emulation for GNU Emacs is designed | |
619 | to make it easy to customize bindings. | |
620 | ||
621 | If you wish to customize the EDT Emulation to use some of your own key | |
622 | bindings, you need to make a private version of edt-user.el in your own | |
623 | private lisp directory. There are two sample files edt-user.el1 and | |
624 | edt-user.el2 for you to use as templates and for ideas. Look at | |
625 | edt-user.el1 first. Unless you will be using two or more very different | |
626 | types of terminals on the same system, you need not look at edt-user.el2. | |
627 | ||
628 | First, you need to have your own private lisp directory, say ~/lisp, and | |
629 | you should add it to the GNU Emacs load path. | |
630 | ||
631 | NOTE: A few sites have different load-path requirements, so the above | |
632 | directions may need some modification if your site has such special | |
633 | needs. | |
634 | ||
635 | ||
636 | Creating your own edt-user.el file: | |
637 | ||
638 | A sample edt-user.el file is attached to the end of this user documentation. | |
639 | You should use it as a guide to learn how you can customize EDT emulation | |
640 | bindings to your own liking. Names used to identify the set of LK-201 | |
641 | keypad and function keys are: | |
642 | ||
643 | Keypad Keys: | |
644 | PF1 PF2 PF3 PF4 | |
645 | KP7 KP8 KP9 KP- | |
646 | KP4 KP5 KP6 KP, | |
647 | KP1 KP2 KP3 | |
648 | KP0 KPP KPE | |
649 | ||
650 | Arrow Keys: | |
651 | LEFT RIGHT DOWN UP | |
652 | ||
653 | Function Keys: | |
654 | F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F13 F14 | |
655 | HELP DO F17 F18 F19 F20 | |
656 | ||
657 | FIND INSERT REMOVE | |
658 | SELECT PREVIOUS NEXT | |
659 | ||
660 | Note: | |
661 | Many VT-200 terminals, and above, steal function keys F1 thru | |
662 | F5 for terminal setup control and don't send anything to the | |
663 | host if pressed. So customizing bindings to these keys may | |
664 | not work for you. | |
665 | ||
4f6e7915 GM |
666 | There are three basic functions that do the EDT emulation custom bindings: |
667 | edt-bind-key, edt-bind-gold-key, and edt-bind-function-key. | |
a933dad1 DL |
668 | |
669 | The first two are for binding functions to keys which are standard across most | |
670 | keyboards. This makes them keyboard independent, making it possible to define | |
671 | these key bindings for all terminals in the file edt.el. | |
672 | ||
4f6e7915 | 673 | The first, edt-bind-key, is used typically to bind emacs commands to |
a933dad1 DL |
674 | control keys, although some people use it to bind commands to other keys, as |
675 | well. (For example, some people use it to bind the VT200 seldom used | |
676 | back-tick key (`) to the function "ESC-prefix" so it will behave like an ESC | |
677 | key.) The second function, edt-bind-gold-key, is used to bind emacs commands | |
678 | to gold key sequences involving alpha-numeric keys, special character keys, | |
679 | and control keys. | |
680 | ||
4f6e7915 GM |
681 | The third function, edt-bind-function-key, is terminal dependent and is defined |
682 | in a terminal specific file (see edt-vt100.el for example). It is used to bind | |
683 | emacs commands to LK-201 function keys, to keypad keys, and to gold sequences | |
684 | of those keys. | |
a933dad1 DL |
685 | |
686 | ||
687 | SPECIFYING WORD ENTITIES: | |
688 | ||
689 | The variable edt-word-entities is used to emulate EDT's SET ENTITY WORD | |
690 | command. It contains a list of characters to be treated as words in | |
691 | themselves. If the user does not define edt-word-entities in his/her .emacs | |
692 | file, then it is set up with the EDT default containing only TAB. | |
693 | ||
694 | The characters are stored in the list by their numerical values, not as | |
695 | strings. Emacs supports several ways to specify the numerical value of a | |
696 | character. One method is to use the question mark: ?A means the numerical | |
697 | value for A, ?/ means the numerical value for /, and so on. Several | |
698 | unprintable characters have special representations: | |
699 | ||
700 | ?\b specifies BS, C-h | |
701 | ?\t specifies TAB, C-i | |
702 | ?\n specifies LFD, C-j | |
703 | ?\v specifies VTAB, C-k | |
704 | ?\f specifies FF, C-l | |
705 | ?\r specifies CR, C-m | |
706 | ?\e specifies ESC, C-[ | |
707 | ?\\ specifies \ | |
708 | ||
709 | Here are some examples: | |
710 | ||
711 | (setq edt-word-entities '(?\t ?- ?/)) ;; Specifies TAB, - , and / | |
712 | (setq edt-word-entities '(?\t) ;; Specifies TAB, the default | |
713 | ||
714 | You can also specify characters by their decimal ascii values: | |
715 | ||
716 | (setq edt-word-entities '(9 45 47)) ;; Specifies TAB, - , and / | |
717 | ||
718 | ||
719 | ENABLING EDT CONTROL KEY SEQUENCE BINDINGS: | |
720 | ||
721 | Where EDT key bindings and GNU Emacs key bindings conflict, the default GNU | |
722 | Emacs key bindings are retained by default. Some diehard EDT users may not | |
723 | like this. So, if the variable edt-use-EDT-control-key-bindings is set to | |
724 | true in a user's .emacs file, then the default EDT Emulation mode will enable | |
725 | most of the original EDT control key sequence bindings. If you wish to do | |
726 | this, add the following line to your .emacs file: | |
727 | ||
728 | (setq edt-use-EDT-control-key-bindings t) | |
729 | ||
4f6e7915 GM |
730 | |
731 | SETTING SCROLL MARGINS: | |
732 | ||
733 | Scroll margins at the top and bottom of the window are now supported. (The | |
734 | design was copied from tpu-extras.el.) By default, this feature is enabled | |
735 | with the top margin set to 10% of the window and the bottom margin set to 15% | |
736 | of the window. To change these settings, you can invoke the function | |
737 | edt-set-scroll-margins in your .emacs file. For example, the following line | |
738 | ||
739 | (edt-set-scroll-margins "20%" "25%") | |
740 | ||
741 | sets the top margin to 20% of the window and the bottom margin to 25% of the | |
742 | window. To disable this feature, set each margin to 0%. You can also invoke | |
743 | edt-set-scroll-margins interactively while EDT Emulation is active to change | |
744 | the settings for that session. | |
745 | ||
746 | NOTE: Another way to set the scroll margins is to use the Emacs customization | |
747 | feature (not available in Emacs 19) to set the following two variables | |
748 | directly: | |
749 | ||
750 | edt-top-scroll-margin and edt-bottom-scroll-margin | |
751 | ||
752 | Enter the Emacs `customize' command. First select the Editing group and then | |
753 | select the Emulations group. Finally, select the Edt group and follow the | |
754 | directions. | |
