- ============================================================================
-
- 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 (kgallagh@spd.dsccc.com).
-
- 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 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. (See the man page on xmodmap for 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 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 Linux for the GNU Emacs EDT Emulation
- !
- keycode 22 = BackSpace
- keycode 77 = F12
- keycode 96 = Num_Lock
-
- Feed the file to the xmodmap command and all the PC keypad keys will now
- be configurable for the emulation of an LK-201 keypad (less the comma
- key), the standard keyboard supplied with DEC terminals VT-200 and above.
- This file switches the role of the F12 and NumLock keys. It also
- modifies the definition of the Delete key above the arrow keys so that it
- can be assigned a keybinding independently of the the BackSpace key.
-
- NOTE: It is necessary to have NumLock ON for the PC keypad to emulate the
- LK-201 keypad properly.
-
-
- 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 it's 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.
