29 ;;; Commentary:
30 ;;
32 ;; This is Version 4.0 of the EDT Emulation for Emacs 19 and above.
33 ;; It comes with special functions which replicate nearly all of EDT's
34 ;; keypad mode behavior. It sets up default keypad and function key
35 ;; bindings which closely match those found in EDT. Support is
36 ;; provided so that users may reconfigure most keypad and function key
37 ;; bindings to their own liking.
39 ;; NOTE: Version 4.0 contains several enhancements. See the
40 ;; Enhancement section below for the details.
42 ;; Getting Started:
44 ;; To start the EDT Emulation, first start Emacs and then enter
45 ;;
46 ;; M-x edt-emulation-on
47 ;;
48 ;; to begin the emulation. After initialization is complete, the
49 ;; following message will appear below the status line informing you
50 ;; that the emulation has been enabled: "Default EDT keymap active".
52 ;; You can have the EDT Emulation start up automatically, each time
53 ;; you initiate a GNU Emacs session, by adding the following line to
54 ;; your .emacs file:
55 ;;
56 ;; (add-hook term-setup-hook 'edt-emulation-on)
58 ;; IMPORTANT: Be sure to read the file, edt-user.doc, located in the
59 ;; Emacs "etc" directory. It contains very helpful user information.
61 ;; The EDT emulation consists of the following files:
62 ;;
63 ;; edt-user.doc - User Instructions and Sample Customization File
64 ;; edt.el - EDT Emulation Functions and Default Configuration
65 ;; edt-lk201.el - Built-in support for DEC LK-201 Keyboards
66 ;; edt-vt100.el - Built-in support for DEC VT-100 (and above) terminals
67 ;; edt-pc.el - Built-in support for PC 101 Keyboards under MS-DOS
68 ;; edt-mapper.el - Create an EDT LK-201 Map File for Keyboards Without
69 ;; Built-in Support
71 ;; Enhancements:
73 ;; Version 4.0 contains the following enhancements:
75 ;; 1. Scroll margins at the top and bottom of the window are now
76 ;; supported. (The design was copied from tpu-extras.el.) By
77 ;; default, this feature is enabled, with the top margin set to
78 ;; 10% of the window and the bottom margin set to 15% of the
79 ;; window. To change these settings, you can invoke the function
80 ;; edt-set-scroll-margins in your .emacs file. For example, the
81 ;; following line
82 ;;
83 ;; (edt-set-scroll-margins "20%" "25%")
84 ;;
85 ;; sets the top margin to 20% of the window and the bottom margin
86 ;; to 25% of the window. To disable this feature, set each
87 ;; margin to 0%. You can also invoke edt-set-scroll-margins
88 ;; interactively while EDT Emulation is active to change the
89 ;; settings for that session.
90 ;;
91 ;; NOTE: Another way to set the scroll margins is to use the
92 ;; Emacs customization feature (not available in Emacs 19) to set
93 ;; the following two variables directly:
94 ;;
95 ;; edt-top-scroll-margin and edt-bottom-scroll-margin
96 ;;
97 ;; Enter the Emacs `customize' command. First select the Editing
98 ;; group and then select the Emulations group. Finally, select
99 ;; the Edt group and follow the directions.
100 ;;
101 ;; 2. The SUBS command is now supported and bound to GOLD-Enter by
102 ;; default. (This design was copied from tpu-edt.el.) Note, in
103 ;; earlier versions of EDT Emulation, GOLD-Enter was assigned to
104 ;; the Emacs function `query-replace'. The binding of
105 ;; `query-replace' has been moved to GOLD-/. If you prefer to
106 ;; restore `query-replace' to GOLD-Enter, then use an EDT user
107 ;; customization file, edt-user.el, to do this. See edt-user.doc
108 ;; for details.
110 ;; 3. EDT Emulation now also works in XEmacs, including the
111 ;; highlighting of selected text.
113 ;; 4. If you access a workstation using an X Server, observe that
114 ;; the initialization file generated by edt-mapper.el will now
115 ;; contain the name of the X Server vendor. This is a
116 ;; convenience for those who have access to their Unix account
117 ;; from more than one type of X Server. Since different X
118 ;; Servers typically require different EDT emulation
119 ;; initialization files, edt-mapper.el will now generate these
120 ;; different initialization files and save them with different
121 ;; names. Then, the correct initialization file for the
122 ;; particular X server in use is loaded correctly automatically.
124 ;; 5. Also, edt-mapper.el is now capable of binding an ASCII key
125 ;; sequence, providing the ASCII key sequence prefix is already
126 ;; known by Emacs to be a prefix. As a result of providing this
127 ;; support, some terminal/keyboard/window system configurations,
128 ;; which don't have a complete set of sensible function key
129 ;; bindings built into Emacs in `function-key-map', can still be
130 ;; configured for use with EDT Emulation. (Note: In a few rare
131 ;; circumstances this does not work properly. In particular, it
132 ;; does not work if a subset of the leading ASCII characters in a
133 ;; key sequence are recognized by Emacs as having an existing
134 ;; binding. For example, if the keypad 7 (KP-7) key generates
135 ;; the sequence \"<ESC>Ow\" and \"<ESC>O\" is already bound to a
136 ;; function, pressing KP-7 when told to do so by edt-mapper.el
137 ;; will result in edt-mapper.el incorrectly mapping \"<ESC>O\" to
138 ;; KP-7 and \"w\" to KP-8. If something like this happens to
139 ;; you, it is probably a bug in the support for your keyboard
140 ;; within Emacs OR a bug in the Unix termcap/terminfo support for
141 ;; your terminal OR a bug in the terminal emulation software you
142 ;; are using.)
144 ;; 6. The edt-quit function (bound to GOLD-q by default) has been
145 ;; modified to warn the user when file-related buffer
146 ;; modifications exist. It now cautions the user that those
147 ;; modifications will be lost if the user quits without saving
148 ;; those buffers.

338 ;;;;
339 ;;;; EDT Emulation Commands
340 ;;;;
342 ;;; Almost all of EDT's keypad mode commands have equivalent Emacs
343 ;;; function counterparts. But many of these counterparts behave
344 ;;; somewhat differently in Emacs.
345 ;;;
346 ;;; So, the following Emacs functions emulate, where practical, the
347 ;;; exact behavior of the corresponding EDT keypad mode commands. In
348 ;;; a few cases, the emulation is not exact, but it should be close
349 ;;; enough for most EDT die-hards.
350 ;;;
352 ;;;
353 ;;; PAGE
354 ;;;
355 ;;; Emacs uses the regexp assigned to page-delimiter to determine what
356 ;;; marks a page break. This is normally "^\f", which causes the
357 ;;; edt-page command to ignore form feeds not located at the beginning
358 ;;; of a line. To emulate the EDT PAGE command exactly,
359 ;;; page-delimiter is set to "\f" when EDT emulation is turned on, and
360 ;;; restored to its original value when EDT emulation is turned off.
361 ;;; But this can be overridden if the EDT definition is not desired by
362 ;;; placing
363 ;;;
364 ;;; (setq edt-keep-current-page-delimiter t)
365 ;;;
366 ;;; in your .emacs file.
369 "Move forward to just after next page delimiter.
370 Argument NUM is the number of page delimiters to move."
382 "Move backward to just after previous page delimiter.
383 Argument NUM is the number of page delimiters to move."
394 "Move in current direction to next page delimiter.
395 Argument NUM is the number of page delimiters to move."
401 ;;;
402 ;;; SECT
403 ;;;
404 ;;; EDT defaults a section size to be 16 lines of its one and only
405 ;;; 24-line window. That's two-thirds of the window at a time. The
406 ;;; EDT SECT commands moves the cursor, not the window.
407 ;;;
408 ;;; This emulation of EDT's SECT moves the cursor approximately
409 ;;; two-thirds of the current window at a time.
412 "Move cursor forward two-thirds of a window's number of lines.
413 Argument NUM is the number of sections to move."
420 "Move cursor backward two-thirds of a window.
421 Argument NUM is the number of sections to move."
427 "Move in current direction a full window.
428 Argument NUM is the number of sections to move."

435 ;;; BEGINNING OF LINE
436 ;;;
437 ;;; EDT's beginning-of-line command is not affected by current
438 ;;; direction, for some unknown reason.
441 "Move backward to next beginning of line mark.
442 Argument NUM is the number of BOL marks to move."
455 ;;;
456 ;;; EOL (End of Line)

460 "Move forward to next end of line mark.
461 Argument NUM is the number of EOL marks to move."
472 "Move backward to next end of line mark.

483 "Move in current direction to next end of line mark.
484 Argument NUM is the number of EOL marks to move."
490 ;;;
491 ;;; WORD
492 ;;;
493 ;;; This one is a tad messy. To emulate EDT's behavior everywhere in
494 ;;; the file (beginning of file, end of file, beginning of line, end
495 ;;; of line, etc.) it takes a bit of special handling.
496 ;;;
497 ;;; The variable edt-word-entities contains a list of characters which
498 ;;; are to be viewed as distinct words where ever they appear in the
499 ;;; buffer. This emulates the EDT line mode command SET ENTITY WORD.
503 "Move forward to first character of next word."
527 "Move backward to first character of previous word."

2055 Ack!! You're running the Enhanced EDT Emulation without loading an
2056 EDT key mapping file. To create an EDT key mapping file, run the
2057 edt-mapper.el program. It is safest to run it from an Emacs loaded
2058 without any of your own customizations found in your .emacs file, etc.
2059 The reason for this is that some user customizations confuse edt-mapper.
2060 You can do this by quitting Emacs and then invoking Emacs again as
2061 follows:
2063 emacs -q -l edt-mapper.el
2065 [NOTE: If you do nothing out of the ordinary in your .emacs file, and
2066 the search for edt-mapper.el is successful, you can try running it now.]
