27 ;;; Commentary:
28 ;;
30 ;; This is Version 4.0 of the EDT Emulation for Emacs 19 and above.
31 ;; It comes with special functions which replicate nearly all of EDT's
32 ;; keypad mode behavior. It sets up default keypad and function key
33 ;; bindings which closely match those found in EDT. Support is
34 ;; provided so that users may reconfigure most keypad and function key
35 ;; bindings to their own liking.
37 ;; NOTE: Version 4.0 contains several enhancements. See the
38 ;; Enhancement section below for the details.
40 ;; Getting Started:
42 ;; To start the EDT Emulation, first start Emacs and then enter
43 ;;
44 ;; M-x edt-emulation-on
45 ;;
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".
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)
56 ;; IMPORTANT: Be sure to read the file, edt-user.doc, located in the
57 ;; Emacs "etc" directory. It contains very helpful user information.
59 ;; The EDT emulation consists of the following files:
60 ;;
61 ;; edt-user.doc - User Instructions and Sample Customization File
62 ;; edt.el - EDT Emulation Functions and Default Configuration
63 ;; edt-lk201.el - Built-in support for DEC LK-201 Keyboards
64 ;; edt-vt100.el - Built-in support for DEC VT-100 (and above) terminals
65 ;; edt-pc.el - Built-in support for PC 101 Keyboards under MS-DOS
66 ;; edt-mapper.el - Create an EDT LK-201 Map File for Keyboards Without
67 ;; Built-in Support
69 ;; Enhancements:
71 ;; Version 4.0 contains the following enhancements:
73 ;; 1. Scroll margins at the top and bottom of the window are now
74 ;; supported. (The design was copied from tpu-extras.el.) By
75 ;; default, this feature is enabled, with the top margin set to
76 ;; 10% of the window and the bottom margin set to 15% of the
77 ;; window. To change these settings, you can invoke the function
78 ;; edt-set-scroll-margins in your .emacs file. For example, the
79 ;; following line
80 ;;
81 ;; (edt-set-scroll-margins "20%" "25%")
82 ;;
83 ;; sets the top margin to 20% of the window and the bottom margin
84 ;; to 25% of the window. To disable this feature, set each
85 ;; margin to 0%. You can also invoke edt-set-scroll-margins
86 ;; interactively while EDT Emulation is active to change the
87 ;; settings for that session.
88 ;;
89 ;; NOTE: Another way to set the scroll margins is to use the
90 ;; Emacs customization feature (not available in Emacs 19) to set
91 ;; the following two variables directly:
92 ;;
93 ;; edt-top-scroll-margin and edt-bottom-scroll-margin
94 ;;
95 ;; Enter the Emacs `customize' command. First select the Editing
96 ;; group and then select the Emulations group. Finally, select
97 ;; the Edt group and follow the directions.
98 ;;
99 ;; 2. The SUBS command is now supported and bound to GOLD-Enter by
100 ;; default. (This design was copied from tpu-edt.el.) Note, in
101 ;; earlier versions of EDT Emulation, GOLD-Enter was assigned to
102 ;; the Emacs function `query-replace'. The binding of
103 ;; `query-replace' has been moved to GOLD-/. If you prefer to
104 ;; restore `query-replace' to GOLD-Enter, then use an EDT user
105 ;; customization file, edt-user.el, to do this. See edt-user.doc
106 ;; for details.
108 ;; 3. EDT Emulation now also works in XEmacs, including the
109 ;; highlighting of selected text.
111 ;; 4. If you access a workstation using an X Server, observe that
112 ;; the initialization file generated by edt-mapper.el will now
113 ;; contain the name of the X Server vendor. This is a
114 ;; convenience for those who have access to their Unix account
115 ;; from more than one type of X Server. Since different X
116 ;; Servers typically require different EDT emulation
117 ;; initialization files, edt-mapper.el will now generate these
118 ;; different initialization files and save them with different
119 ;; names. Then, the correct initialization file for the
120 ;; particular X server in use is loaded correctly automatically.
122 ;; 5. Also, edt-mapper.el is now capable of binding an ASCII key
123 ;; sequence, providing the ASCII key sequence prefix is already
124 ;; known by Emacs to be a prefix. As a result of providing this
125 ;; support, some terminal/keyboard/window system configurations,
126 ;; which don't have a complete set of sensible function key
127 ;; bindings built into Emacs in `function-key-map', can still be
128 ;; configured for use with EDT Emulation. (Note: In a few rare
129 ;; circumstances this does not work properly. In particular, it
130 ;; does not work if a subset of the leading ASCII characters in a
131 ;; key sequence are recognized by Emacs as having an existing
132 ;; binding. For example, if the keypad 7 (KP-7) key generates
133 ;; the sequence \"<ESC>Ow\" and \"<ESC>O\" is already bound to a
134 ;; function, pressing KP-7 when told to do so by edt-mapper.el
135 ;; will result in edt-mapper.el incorrectly mapping \"<ESC>O\" to
136 ;; KP-7 and \"w\" to KP-8. If something like this happens to
137 ;; you, it is probably a bug in the support for your keyboard
138 ;; within Emacs OR a bug in the Unix termcap/terminfo support for
139 ;; your terminal OR a bug in the terminal emulation software you
140 ;; are using.)
142 ;; 6. The edt-quit function (bound to GOLD-q by default) has been
143 ;; modified to warn the user when file-related buffer
144 ;; modifications exist. It now cautions the user that those
145 ;; modifications will be lost if the user quits without saving
146 ;; those buffers.

336 ;;;;
337 ;;;; EDT Emulation Commands
338 ;;;;
340 ;;; Almost all of EDT's keypad mode commands have equivalent Emacs
341 ;;; function counterparts. But many of these counterparts behave
342 ;;; somewhat differently in Emacs.
343 ;;;
344 ;;; So, the following Emacs functions emulate, where practical, the
345 ;;; exact behavior of the corresponding EDT keypad mode commands. In
346 ;;; a few cases, the emulation is not exact, but it should be close
347 ;;; enough for most EDT die-hards.
348 ;;;
350 ;;;
351 ;;; PAGE
352 ;;;
353 ;;; Emacs uses the regexp assigned to page-delimiter to determine what
354 ;;; marks a page break. This is normally "^\f", which causes the
355 ;;; edt-page command to ignore form feeds not located at the beginning
356 ;;; of a line. To emulate the EDT PAGE command exactly,
357 ;;; page-delimiter is set to "\f" when EDT emulation is turned on, and
358 ;;; restored to its original value when EDT emulation is turned off.
359 ;;; But this can be overridden if the EDT definition is not desired by
360 ;;; placing
361 ;;;
362 ;;; (setq edt-keep-current-page-delimiter t)
363 ;;;
364 ;;; in your .emacs file.
367 "Move forward to just after next page delimiter.
368 Argument NUM is the number of page delimiters to move."
380 "Move backward to just after previous page delimiter.
381 Argument NUM is the number of page delimiters to move."
392 "Move in current direction to next page delimiter.
393 Argument NUM is the number of page delimiters to move."
399 ;;;
400 ;;; SECT
401 ;;;
402 ;;; EDT defaults a section size to be 16 lines of its one and only
403 ;;; 24-line window. That's two-thirds of the window at a time. The
404 ;;; EDT SECT commands moves the cursor, not the window.
405 ;;;
406 ;;; This emulation of EDT's SECT moves the cursor approximately
407 ;;; two-thirds of the current window at a time.
410 "Move cursor forward two-thirds of a window's number of lines.
411 Argument NUM is the number of sections to move."
418 "Move cursor backward two-thirds of a window.
419 Argument NUM is the number of sections to move."
425 "Move in current direction a full window.

435 ;;; EDT's beginning-of-line command is not affected by current
436 ;;; direction, for some unknown reason.
439 "Move backward to next beginning of line mark.
440 Argument NUM is the number of BOL marks to move."
453 ;;;
454 ;;; EOL (End of Line)

459 Argument NUM is the number of EOL marks to move."

481 "Move in current direction to next end of line mark.
482 Argument NUM is the number of EOL marks to move."

489 ;;; WORD

491 ;;; This one is a tad messy. To emulate EDT's behavior everywhere in

493 ;;; of line, etc.) it takes a bit of special handling.

496 ;;; are to be viewed as distinct words where ever they appear in the
497 ;;; buffer. This emulates the EDT line mode command SET ENTITY WORD.
501 "Move forward to first character of next word."
525 "Move backward to first character of previous word."

2053 Ack!! You're running the Enhanced EDT Emulation without loading an
2054 EDT key mapping file. To create an EDT key mapping file, run the
2055 edt-mapper.el program. It is safest to run it from an Emacs loaded
2056 without any of your own customizations found in your .emacs file, etc.
2057 The reason for this is that some user customizations confuse edt-mapper.
2058 You can do this by quitting Emacs and then invoking Emacs again as
2059 follows:
2061 emacs -q -l edt-mapper.el
2063 [NOTE: If you do nothing out of the ordinary in your .emacs file, and
2064 the search for edt-mapper.el is successful, you can try running it now.]
