============================================================================
I. OVERVIEW:
This version of the EDT emulation package for GNU Emacs is a substantially
enhanced version of the original. A large part of the original can still be
found here, of course, but much of it has been modified and quite a bit is
new. Many of the ideas found here are borrowed from others. In particular,
some of the code found here was drawn from an earlier re-write of the EDT
package done at DSC in 1989 by Matthew Frohman.
Send bug fixes, suggestions for enhancements, and corrections to this
documentation to Kevin Gallagher (kevingal@onramp.net).
The EDT emulation consists of the following files:
edt-user.doc - User instructions (which you are reading now)
edt.el - EDT Emulation Functions and Default Configuration
edt-lk201.el - Support for DEC LK-201 Keyboards
edt-vt100.el - Support for DEC VT-100 (and above) terminals
edt-mapper.el - Support for Keyboards used under X Windows
edt-pc.el - Support for the PC AT Keyboard under MS-DOS
Several goals were kept in mind when making this version:
1. Emulate EDT Keypad Mode commands closely so that current
EDT users will find that it easy and comfortable to use
GNU Emacs with a small learning curve;
2. Make it easy for a user to customize EDT emulation key
bindings without knowing much about Emacs Lisp;
3. Make it easy to switch between the original EDT default bindings
and the user's customized bindings, without having to exit Emacs.
4. Provide support for some TPU/EVE functions not supported in
EDT.
5. Provide an easy way to restore ALL original Emacs key bindings,
just as they existed before the EDT emulation was first invoked.
6. Support GNU Emacs 19. (Support for GNU Emacs 18 has been dropped.
Also, although there is some code designed to support Xemacs 19
(formerly Lucid Emacs), this is not fully implemented at this
time.
7. When running under X, support highlighting of marked text.
8. Handle terminal configuration under X interactively when the
emulation is invoked for the first time.
9. Support a PC AT keyboard under MS-DOS.
II. TERMINALS/KEYBOARDS SUPPORTED:
Keyboards used under X Windows are supported via the edt-mapper function. The
first time you invoke the emulation under X, the edt-mapper function is run
automatically and the user is prompted to identify which keys the emulation is
to use for the standard keypad and function keys EDT expects (e.g., PF1, PF2,
etc.). This configuration is saved to disk read each time the emulation is
invoked.
In character oriented connections not running a window manager, the following
terminals/keyboards are supported. (1) DEC VT-100 series and higher. This
includes well behaved VT clones and emulators. If you are using a VT series
terminal, be sure that the term environment variable is set properly before
invoking emacs. (2) PC AT keyboard under MS-DOS.
Be sure to read the SPECIAL NOTES FOR SOME PLATFORMS sections to see if those
notes apply to you.
III. STARTING THE EDT EMULATION:
Start up GNU Emacs and enter "M-x edt-emulation-on" to begin the emulation.
After initialization is complete, the following message will appear below the
status line informing you that the emulation has been enabled:
Default EDT keymap active
You can have the EDT Emulation start up automatically, each time you initiate
a GNU Emacs session, by adding the following line to your .emacs file:
(setq term-setup-hook 'edt-emulation-on)
A reference sheet is included (later on) listing the default EDT Emulation key
bindings. This sheet is also accessible on line from within Emacs by pressing
PF2, GOLD H, or HELP (when in the EDT Default Mode).
It is easy to customize key bindings in the EDT Emulation. (See CUSTOMIZING
section, below.) Customizations are placed in a file called edt-user.el. (A
sample edt-user.el file can be found in the CUSTOMIZING section.) If
edt-user.el is found in your GNU Emacs load path during EDT Emulation
initialization, then the following message will appear below the status line
indicating that the emulation has been enabled, enhanced by your own
customizations:
User EDT custom keymap active
Once enabled, it is easy to switch back and forth between your customized EDT
Emulation key bindings and the default EDT Emulation key bindings. It is also
easy to turn off the emulation. Doing so completely restores the original key
bindings in effect just prior to invoking the emulation.
Where EDT key bindings and GNU Emacs key bindings conflict, the default GNU
Emacs key bindings are retained by the EDT emulation by default. If you are a
diehard EDT user you may not like this. The CUSTOMIZING section explains how
to change this default.
IV. SPECIAL NOTES FOR SOME PLATFORMS:
Sun Workstations running X:
Some earlier Sun keyboards do not have arrow keys separate from the
keypad keys. It is difficult to emulate the full EDT keypad and still
retain use of the arrow keys on such keyboards.
The Sun Type 5 keyboard, however, does have separate arrow keys. This
makes it a candidate for setting up a reasonable EDT keypad emulation.
Unfortunately, Sun's default X keynames for the keypad keys don't permit
GNU Emacs to interpret the keypad 2, 4, 6, and 8 keys as something other
than arrow keys, nor use all the top row of keys for PF1 thru PF4 keys.
Here's the contents of an .xmodmaprc file which corrects this problem for
Sun Type 5 keyboards:
! File: .xmodmaprc
!
! Set up Sun Type 5 keypad for use with the GNU Emacs EDT Emulation
!
keycode 53 = KP_Divide
keycode 54 = KP_Multiply
keycode 57 = KP_Decimal
keycode 75 = KP_7
keycode 76 = KP_8
keycode 77 = KP_9
keycode 78 = KP_Subtract
keycode 97 = KP_Enter
keycode 98 = KP_4
keycode 99 = KP_5
keycode 100 = KP_6
keycode 101 = KP_0
keycode 105 = F24
keycode 119 = KP_1
keycode 120 = KP_2
keycode 121 = KP_3
keycode 132 = KP_Add
Feed .xmodmaprc to the xmodmap command and all the Sun Type 5 keypad keys
will now be configurable for the emulation of an LK-201 keypad (less the
comma key). The line
keycode 105 = F24
modifies the NumLock key to be the F24 key which can then be configured
to behave as the PF1 (Gold) key. In doing so, you will no longer
have a NumLock key. If you are using other software under X
which requires a NumLock key, then examine your keyboard and look
for one you don't use and redefine it to be the NumLock key.
Basically, you need to clear the NumLock key from being assigned
as a modifier, assign it to the key of your choice, and then add
it back as a modifier. (See the "General Notes on Using NumLock
for the PF1 Key on a Unix System" section below for further help
on how to do this.)
PC users running MS-DOS:
By default, F1 is configured to emulate the PF1 (GOLD) key. But NumLock
can be used instead if you load a freeware TSR distributed with
MS-Kermit, call gold.com. It is distributed in a file called gold22.zip
and comes with the source code as well as a loadable binary image.
(See edt-pc.el for more information.)
PC users running GNU/Linux:
The default X server configuration of three keys PC AT keyboard keys
needs to be modified to permit the PC keyboard to emulate an LK-201
keyboard properly. Here's the contents of an .xmodmaprc file which makes
these changes for your:
! File: .xmodmaprc
!
! Set up PC keypad under GNU/Linux for the GNU Emacs EDT Emulation
!
clear mod2
keycode 77 = F12
keycode 96 = Num_Lock Pointer_EnableKeys
add mod2 = Num_Lock
Feed the file to the xmodmap command and the PC NumLock keypad
key will now be configurable for the emulation of the PF1 key.
The PC keypad can now emulate an LK-201 keypad (less the comma
key), the standard keyboard supplied with DEC terminals VT-200 and above.
This .xmodmaprc file switches the role of the F12 and NumLock
keys. It has been tested on RedHat GNU/Linux 5.2. Other
versions of GNU/Linux may require different keycodes. (See the
"General Notes on Using NumLock for the PF1 Key on a Unix System"
section below for further help on how to do this.)
NOTE: It is necessary to have NumLock ON for the PC keypad to emulate the
LK-201 keypad properly.
General Notes on Using NumLock for the PF1 Key on a Unix System:
Making the physical NumLock key available for use in the EDT
Emulation requires some modification to the default X Window
settings. Since the keycode assignments vary from system to
system, some investigation is needed to see how to do this on
a particular system.
The following commands should be run and the output examined.
On RedHat GNU/Linux 5.2 on a PC, we get the following output when
running xmodmap.
"xmodmap -pm" yields:
xmodmap: up to 2 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x6d)
mod1 Alt_L (0x40), Alt_R (0x71)
mod2 Num_Lock (0x4d)
mod3
mod4
mod5 Scroll_Lock (0x4e)
Note that Num_Lock is assigned to the modifier mod2. This is
what hides Num_Lock from being seen by Emacs.
Now, "xmodmap -pke" yields:
.
.
.
keycode 77 = Num_Lock Pointer_EnableKeys
.
.
.
keycode 96 = F12
.
.
.
So, in RedHat GNU/Linux 5.2 on a PC, Num_Lock generates keycode
77. The following steps are taken:
1. clear the assignment of Num_Lock to mod2;
2. swap the keycodes assigned to F12 and Num_Lock;
3. assign Num_Lock back to mod2.
The .xmodmaprc file looks like this:
! File: .xmodmaprc
!
! Set up PC keypad under GNU/Linux for the GNU Emacs EDT Emulation
!
clear mod2
keycode 77 = F12
keycode 96 = Num_Lock Pointer_EnableKeys
add mod2 = Num_Lock
So, after executing "xmodmap .xmodmaprc", a press of the physical
F12 key looks like a Num_Lock keypress to X. Also, a press of the
physical NumLock key looks like a press of the F12 key to X.
Now, edt-mapper.el will see "f12" when the physical NumLock key
is pressed, allowing the NumLock key to be used as the EDT PF1
(Gold) key.
V. HOW DOES THIS EDT EMULATION DIFFER FROM REAL EDT?:
In general, you will find that this emulation of EDT replicates most, but not
all, of EDT's most used Keypad Mode editing functions and behavior. It is not
perfect, but most EDT users who have tried the emulation agree that it is
quite good enough to make it easy for die-hard EDT users to move over to using
GNU Emacs.
Here's a list of the most important differences between EDT and this GNU Emacs
EDT Emulation. The list is short but you must be aware of these differences
if you are to use the EDT Emulation effectively.
1. Entering repeat counts works a little differently than in EDT.
EDT allows users to enter a repeat count before entering a command that
accepts repeat counts. For example, when in EDT, pressing these three
keys in sequence, GOLD 5 KP1, will move the cursor in the current
direction 5 words.
Emacs provides two ways to enter repeat counts, though neither involves
using the GOLD key. In Emacs, repeat counts can be entered by using the
ESC key. For example, pressing these keys in sequence, ESC 1 0 KP1, will
move the cursor in the current direction 10 words.
Emacs provides another command called universal-argument that can do the
same thing, plus a few other things. Normally, Emacs has this bound to
C-u.
2. The EDT SUBS command, bound to GOLD ENTER, is NOT supported. The built-in
Emacs query-replace command has been bound to GOLD ENTER, instead. It is
much more convenient to use than SUBS.
3. EDT's line mode commands and nokeypad mode commands are NOT supported
(with one important exception; see item 8 in the Highlights section
below). Although, at first, this may seem like a big omission, the set of
built-in Emacs commands provides a much richer set of capabilities which
more than make up for this omission.
To enter Emacs commands not bound to keys, you can press GOLD KP7 or the
DO key. Emacs will display its own command prompt called Meta-x (M-x).
You can also invoke this prompt the normal Emacs way by entering ESC x.
4. Selected text is highlighted ONLY when running under X Windows. Gnu Emacs
19 does not support highlighting of text on VT series terminals, at this
time.
5. Just like TPU/EVE, The ENTER key is NOT used to terminate input when the
editor prompts you for input. The RETURN key is used, instead. (KP4 and
KP5 do terminate input for the FIND command, just like in EDT, however.)
VI. SOME HIGHLIGHTS IN THIS EDT EMULATION, AND SOME COMPARISONS TO THE
ORIGINAL GNU EMACS EDT EMULATION:
1. The EDT define key command is supported (edt-define-key) and is bound to
C-k in the default EDT mode when EDT control sequence bindings are enabled
or one of the sample edt-user.el customization files is used. The TPU/EVE
learn command is supported but not bound to a key in the default EDT mode
but is bound in the sample edt-user.el files.
Unlike the TPU/EVE learn command, which uses one key to begin the learn
sequence, C-l, and another command to remember the sequence, C-r, this
version of the learn command (edt-learn) serves as a toggle to both begin
and to remember the learn sequence.
Many users who change the meaning of a key with the define key and the
learn commands, would like to be able to restore the original key binding
without having to quit and restart emacs. So a restore key command is
provided to do just that. When invoked, it prompts you to press the key
to which you wish the last replaced key definition restored. It is bound
to GOLD C-k in the default EDT mode when EDT control sequence bindings are
enabled or one of the sample edt-user.el customization files is used.
2. Direction support is fully supported. It is no longer accomplished by
re-defining keys each time the direction is changed. Thus, commands
sensitive to the current direction setting may be bound easily to any key.
3. All original emacs bindings are fully restored when EDT emulation is
turned off.
4. User custom EDT bindings are kept separate from the default EDT bindings.
One can toggle back and forth between the custom EDT bindings and default
EDT bindings.
5. The Emacs functions in edt.el attempt to emulate, where practical, the
exact behavior of the corresponding EDT keypad mode commands. In a few
cases, the emulation is not exact, but we hope you will agree it is close
enough. In a very few cases, we chose to use the Emacs way of handling
things. As mentioned earlier, we do not emulate the EDT SUBS command.
Instead, we chose to use the Emacs query-replace function, which we find
to be easier to use.
6. Emacs uses the regexp assigned to page-delimiter to determine what marks a
page break. This is normally "^\f", which causes the edt-page command to
ignore form feeds not located at the beginning of a line. To emulate the
EDT PAGE command exactly, page-delimiter is set to "\f" when EDT emulation
is turned on, and restored to "^\f" when EDT emulation is turned off.
But, since some users prefer the Emacs definition of a page break, or may
wish to preserve a customized definition of page break, one can override
the EDT definition by placing
(setq edt-keep-current-page-delimiter t)
in your .emacs file.
7. The EDT definition of a section of a terminal window is hardwired to be 16
lines of its one-and-only 24-line window (the EDT SECT command bound to
KP8). That's two-thirds of the window at a time. Since Emacs, like
TPU/EVE, can handle multiple windows of sizes of other than 24 lines, the
definition of section used here has been modified to two-thirds of the
current window. (There is also an edt-scroll-window function which you
may prefer over the SECT emulation.)
8. Cursor movement and deletion involving word entities is identical to EDT.
This, above all else, gives the die-hard EDT user a sense of being at
home. Also, an emulation of EDT's SET ENTITY WORD command is provided,
for those users who like to customize movement by a word at a time to
their own liking.
9. EDT's FIND and FNDNXT are supported.
10. EDT's APPEND and REPLACE commands are supported.
11. CHNGCASE is supported. It works on individual characters or selected
text, if SELECT is active. In addition, two new commands are provided:
edt-lowercase and edt-uppercase. They work on individual WORDS or
selected text, if SELECT is active.
12. Form feed and tab insert commands are supported.
13. A new command, edt-duplicate-word, is provided. If you experiment with
it, you might find it to be surprisingly useful and may wonder how you
ever got along without it! It is assigned to C-j in the sample
edt-user.el customization files.
14. TPU/EVE's Rectangular Cut and Paste functions (originally from the EVE-Plus
package) are supported. But unlike the TPU/EVE versions, these here
support both insert and overwrite modes. The seven rectangular functions
are bound to F7, F8, GOLD-F8, F9, GOLD-F9, F10, and GOLD-F10 in the
default EDT mode.
15. The original EDT emulation package set up many default regular and GOLD
bindings. We tried to preserve most (but not all!) of these, so users of
the original emulation package will feel more at home.
Nevertheless, there are still many GOLD key sequences which are not bound
to any functions. These are prime candidates to use for your own
customizations.
Also, there are several commands in edt.el not bound to any key. So, you
will find it worthwhile to look through edt.el for functions you may wish
to add to your personal customized bindings.
16. The VT200/VT300 series terminals steal the function keys F1 to F5 for
their own use. These do not generate signals which are sent to the host.
So, edt.el does not assign any default bindings to F1 through F5.
In addition, our VT220 terminals generate an interrupt when the F6 key is
pressed (^C or ^Y, can't remember which) and not the character sequence
documented in the manual. So, binding emacs commands to F6 will not work
if your terminal behaves the same way.
17. The VT220 terminal has no ESC, BS, nor LF keys, as does a VT100. So the
default EDT bindings adopt the standard DEC convention of having the F11,
F12, and F13 keys, on a VT200 series (and above) terminal, assigned to the
same EDT functions that are bound to ESC, BS, and LF on a VT100 terminal.
18. Each user, through the use of a private edt-user.el file, can customize,
very easily, personal EDT emulation bindings.
19. The EDT SELECT and RESET functions are supported. However, unlike EDT,
pressing RESET to cancel text selection does NOT reset the existing
setting of the current direction.
We also provide a TPU/EVE like version of the single SELECT/RESET
function, called edt-toggle-select, which makes the EDT SELECT function
into a toggle on/off switch. That is, if selection is ON, pressing SELECT
again turns selection off (cancels selection). This function is used in
the sample edt-user.el customization files.
VII. CUSTOMIZING:
Most EDT users, at one time or another, make some custom key bindings, or
use someone else's custom key bindings, which they come to depend upon just as
if they were built-in bindings. This EDT Emulation for GNU Emacs is designed
to make it easy to customize bindings.
If you wish to customize the EDT Emulation to use some of your own key
bindings, you need to make a private version of edt-user.el in your own
private lisp directory. There are two sample files edt-user.el1 and
edt-user.el2 for you to use as templates and for ideas. Look at
edt-user.el1 first. Unless you will be using two or more very different
types of terminals on the same system, you need not look at edt-user.el2.
First, you need to have your own private lisp directory, say ~/lisp, and
you should add it to the GNU Emacs load path.
NOTE: A few sites have different load-path requirements, so the above
directions may need some modification if your site has such special
needs.
Creating your own edt-user.el file:
A sample edt-user.el file is attached to the end of this user documentation.
You should use it as a guide to learn how you can customize EDT emulation
bindings to your own liking. Names used to identify the set of LK-201
keypad and function keys are:
Keypad Keys:
PF1 PF2 PF3 PF4
KP7 KP8 KP9 KP-
KP4 KP5 KP6 KP,
KP1 KP2 KP3
KP0 KPP KPE
Arrow Keys:
LEFT RIGHT DOWN UP
Function Keys:
F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F13 F14
HELP DO F17 F18 F19 F20
FIND INSERT REMOVE
SELECT PREVIOUS NEXT
Note:
Many VT-200 terminals, and above, steal function keys F1 thru
F5 for terminal setup control and don't send anything to the
host if pressed. So customizing bindings to these keys may
not work for you.
There are three basic functions that do the EDT emulation bindings:
edt-bind-standard-key, edt-bind-gold-key, and edt-bind-function-key.
The first two are for binding functions to keys which are standard across most
keyboards. This makes them keyboard independent, making it possible to define
these key bindings for all terminals in the file edt.el.
The first, edt-bind-standard-key, is used typically to bind emacs commands to
control keys, although some people use it to bind commands to other keys, as
well. (For example, some people use it to bind the VT200 seldom used
back-tick key (`) to the function "ESC-prefix" so it will behave like an ESC
key.) The second function, edt-bind-gold-key, is used to bind emacs commands
to gold key sequences involving alpha-numeric keys, special character keys,
and control keys.
The third function, edt-bind-function-key, is terminal dependent and is
defined in a terminal specific file (see edt-vt100.el for example). It is
used to bind emacs commands to function keys, to keypad keys, and to gold
sequences of those keys.
WARNING: Each of the three functions, edt-bind-function-key,
edt-bind-gold-key, and edt-bind-standard-key, has an optional
last argument. The optional argument should NOT be used in
edt-user.el! When the optional argument is missing, each
function knows to make the key binding part of the user's EDT
custom bindings, which is what you want to do in edt-user.el!
The EDT default bindings are set up in edt.el by calling these
same functions with the optional last argument set to "t". So, if
you decide to copy such function calls from edt.el to edt-user.el
for subsequent modification, BE SURE TO DELETE THE "t" AT THE END
OF EACH PARAMETER LIST!
SPECIFYING WORD ENTITIES:
The variable edt-word-entities is used to emulate EDT's SET ENTITY WORD
command. It contains a list of characters to be treated as words in
themselves. If the user does not define edt-word-entities in his/her .emacs
file, then it is set up with the EDT default containing only TAB.
The characters are stored in the list by their numerical values, not as
strings. Emacs supports several ways to specify the numerical value of a
character. One method is to use the question mark: ?A means the numerical
value for A, ?/ means the numerical value for /, and so on. Several
unprintable characters have special representations:
?\b specifies BS, C-h
?\t specifies TAB, C-i
?\n specifies LFD, C-j
?\v specifies VTAB, C-k
?\f specifies FF, C-l
?\r specifies CR, C-m
?\e specifies ESC, C-[
?\\ specifies \
Here are some examples:
(setq edt-word-entities '(?\t ?- ?/)) ;; Specifies TAB, - , and /
(setq edt-word-entities '(?\t) ;; Specifies TAB, the default
You can also specify characters by their decimal ascii values:
(setq edt-word-entities '(9 45 47)) ;; Specifies TAB, - , and /
ENABLING EDT CONTROL KEY SEQUENCE BINDINGS:
Where EDT key bindings and GNU Emacs key bindings conflict, the default GNU
Emacs key bindings are retained by default. Some diehard EDT users may not
like this. So, if the variable edt-use-EDT-control-key-bindings is set to
true in a user's .emacs file, then the default EDT Emulation mode will enable
most of the original EDT control key sequence bindings. If you wish to do
this, add the following line to your .emacs file:
(setq edt-use-EDT-control-key-bindings t)

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