41 ;; %% Introduction
43 ;; TPU-edt emulates the popular DEC VMS editor EDT (actually, it emulates
44 ;; DEC TPU's EDT emulation, hence the name TPU-edt). TPU-edt features the
45 ;; following TPU/edt functionality:
47 ;; . EDT keypad
48 ;; . On-line help
49 ;; . Repeat counts
50 ;; . Scroll margins
51 ;; . Learn sequences
52 ;; . Free cursor mode
53 ;; . Rectangular cut and paste
54 ;; . Multiple windows and buffers
55 ;; . TPU line-mode REPLACE command
56 ;; . Wild card search and substitution
57 ;; . Configurable through an initialization file
58 ;; . History recall of search strings, file names, and commands
60 ;; Please note that TPU-edt does NOT emulate TPU. It emulates TPU's EDT
61 ;; emulation. Very few TPU line-mode commands are supported.
63 ;; TPU-edt, like its VMS cousin, works on VT-series terminals with DEC
64 ;; style keyboards. VT terminal emulators, including xterm with the
65 ;; appropriate key translations, work just fine too.
67 ;; TPU-edt works with X-windows. This is accomplished through a TPU-edt
68 ;; X key map. The tpu-mapper command creates this map and stores it in a
69 ;; file. See the tpu-mapper command help for more information, or just
70 ;; run it and follow the directions.
73 ;; %% Differences Between TPU-edt and DEC TPU/edt
75 ;; In some cases, Emacs doesn't support text highlighting, so selected
76 ;; regions are not shown in inverse video. Emacs uses the concept of "the
77 ;; mark". The mark is set at one end of a selected region; the cursor is
78 ;; at the other. In cases where the selected region cannot be shown in
79 ;; inverse video an at sign (@) appears in the mode line when mark is set.
80 ;; The native Emacs command ^X^X (Control-X twice) exchanges the cursor
81 ;; with the mark; this provides a handy way to find the location of the
82 ;; mark.
84 ;; In TPU the cursor can be either bound or free. Bound means the cursor
85 ;; cannot wander outside the text of the file being edited. Free means
86 ;; the arrow keys can move the cursor past the ends of lines. Free is the
87 ;; default mode in TPU; bound is the only mode in EDT. Bound is the only
88 ;; mode in the base version of TPU-edt; optional extensions add an
89 ;; approximation of free mode, see the commentary in tpu-extras.el for
90 ;; details.
92 ;; Like TPU, Emacs uses multiple buffers. Some buffers are used to hold
93 ;; files you are editing; other "internal" buffers are used for Emacs's own
94 ;; purposes (like showing you help). Here are some commands for dealing
95 ;; with buffers.
97 ;; Gold-B moves to next buffer, including internal buffers
98 ;; Gold-N moves to next buffer containing a file
99 ;; Gold-M brings up a buffer menu (like TPU "show buffers")
101 ;; Emacs is very fond of throwing up new windows. Dealing with all these
102 ;; windows can be a little confusing at first, so here are a few commands
103 ;; to that may help:
105 ;; Gold-Next_Scr moves to the next window on the screen
106 ;; Gold-Prev_Scr moves to the previous window on the screen
107 ;; Gold-TAB also moves to the next window on the screen
109 ;; Control-x 1 deletes all but the current window
110 ;; Control-x 0 deletes the current window
112 ;; Note that the buffers associated with deleted windows still exist!
114 ;; Like TPU, TPU-edt has a "command" function, invoked with Gold-KP7 or
115 ;; Do. Most of the commands available are Emacs commands. Some TPU
116 ;; commands are available, they are: replace, exit, quit, include, and
117 ;; Get (unfortunately, "get" is an internal Emacs function, so we are
118 ;; stuck with "Get" - to make life easier, Get is available as Gold-g).
120 ;; TPU-edt supports the recall of commands, file names, and search
121 ;; strings. The history of strings recalled differs slightly from
122 ;; TPU/edt, but it is still very convenient.
124 ;; Help is available! The traditional help keys (Help and PF2) display
125 ;; a small help file showing the default keypad layout, control key
126 ;; functions, and Gold key functions. Pressing any key inside of help
127 ;; splits the screen and prints a description of the function of the
128 ;; pressed key. Gold-PF2 invokes the native Emacs help, with its
129 ;; zillions of options.
131 ;; Thanks to Emacs, TPU-edt has some extensions that may make your life
132 ;; easier, or at least more interesting. For example, Gold-r toggles
133 ;; TPU-edt rectangular mode. In rectangular mode, Remove and Insert work
134 ;; on rectangles. Likewise, Gold-* toggles TPU-edt regular expression
135 ;; mode. In regular expression mode Find, Find Next, and the line-mode
136 ;; replace command work with regular expressions. [A regular expression
137 ;; is a pattern that denotes a set of strings; like VMS wildcards.]
139 ;; Emacs also gives TPU-edt the undo and occur functions. Undo does
140 ;; what it says; it undoes the last change. Multiple undos in a row
141 ;; undo multiple changes. For your convenience, undo is available on
142 ;; Gold-u. Occur shows all the lines containing a specific string in
143 ;; another window. Moving to that window, and typing ^C^C (Control-C
144 ;; twice) on a particular line moves you back to the original window
145 ;; at that line. Occur is on Gold-o.
147 ;; Finally, as you edit, remember that all the power of Emacs is at
148 ;; your disposal. It really is a fantastic tool. You may even want to
149 ;; take some time and read the Emacs tutorial; perhaps not to learn the
150 ;; native Emacs key bindings, but to get a feel for all the things
151 ;; Emacs can do for you. The Emacs tutorial is available from the
152 ;; Emacs help function: "Gold-PF2 t"
155 ;; %% Starting TPU-edt
157 ;; All you have to do to start TPU-edt, is turn it on. This can be
158 ;; done from the command line when running Emacs.
160 ;; prompt> emacs -f tpu-edt
162 ;; If you've already started Emacs, turn on TPU-edt using the tpu-edt
163 ;; command. First press `M-x' (that's usually `ESC' followed by `x')
164 ;; and type `tpu-edt' followed by a carriage return.
166 ;; If you like TPU-edt and want to use it all the time, you can start
167 ;; TPU-edt using the Emacs initialization file, .emacs. Simply add
168 ;; the following line to your init file:
170 ;; (tpu-edt)
172 ;; That's all you need to do to start TPU-edt.
175 ;; %% Customizing TPU-edt using the Emacs Initialization File
177 ;; The following is a sample Emacs initialization file. It shows how to
178 ;; invoke TPU-edt, and how to customize it.
180 ;; ; .emacs - a sample Emacs initialization file
182 ;; ; Turn on TPU-edt
183 ;; (tpu-edt)
185 ;; ; Set scroll margins 10% (top) and 15% (bottom).
186 ;; (tpu-set-scroll-margins "10%" "15%")
188 ;; ; Load the vtxxx terminal control functions.
189 ;; (load "vt-control" t)
191 ;; ; TPU-edt treats words like EDT; here's how to add word separators.
192 ;; ; Note that backslash (\) and double quote (") are quoted with '\'.
193 ;; (tpu-add-word-separators "]\\[-_,.\"=+()'/*#:!&;$")
195 ;; ; Emacs is happy to save files without a final newline; other Unix
196 ;; ; programs hate that! Here we make sure that files end with newlines.
197 ;; (setq require-final-newline t)
199 ;; ; Emacs uses Control-s and Control-q. Problems can occur when using
200 ;; ; Emacs on terminals that use these codes for flow control (Xon/Xoff
201 ;; ; flow control). These lines disable Emacs's use of these characters.
202 ;; (global-unset-key "\C-s")
203 ;; (global-unset-key "\C-q")
205 ;; ; The Emacs universal-argument function is very useful.
206 ;; ; This line maps universal-argument to Gold-PF1.
207 ;; (define-key tpu-gold-map [kp_f1] 'universal-argument) ; Gold-PF1
209 ;; ; Make KP7 move by paragraphs, instead of pages.
210 ;; (define-key tpu-global-map [kf_7] 'tpu-paragraph) ; KP7
212 ;; ; Repeat the preceding mappings for X-windows.
213 ;; (cond
214 ;; (window-system
215 ;; (define-key tpu-global-map [kp_7] 'tpu-paragraph) ; KP7
216 ;; (define-key tpu-gold-map [kp_f1] 'universal-argument))) ; GOLD-PF1
218 ;; ; Display the TPU-edt version.
219 ;; (tpu-version)
222 ;; %% Regular Expressions in TPU-edt
224 ;; Gold-* toggles TPU-edt regular expression mode. In regular expression
225 ;; mode, find, find next, replace, and substitute accept Emacs regular
226 ;; expressions. A complete list of Emacs regular expressions can be found
227 ;; using the Emacs "info" command (it's somewhat like the VMS help
228 ;; command). Try the following sequence of commands:
230 ;; DO info <enter info mode>
231 ;; m emacs <select the "emacs" topic>
232 ;; m regexs <select the "regular expression" topic>
234 ;; Type "q" to quit out of info mode.
236 ;; There is a problem in regular expression mode when searching for empty
237 ;; strings, like beginning-of-line (^) and end-of-line ($). When searching
238 ;; for these strings, find-next may find the current string, instead of the
239 ;; next one. This can cause global replace and substitute commands to loop
240 ;; forever in the same location. For this reason, commands like
242 ;; replace "^" "> " <add "> " to beginning of line>
243 ;; replace "$" "00711" <add "00711" to end of line>
245 ;; may not work properly.
247 ;; Commands like those above are very useful for adding text to the
248 ;; beginning or end of lines. They might work on a line-by-line basis, but
249 ;; go into an infinite loop if the "all" response is specified. If the
250 ;; goal is to add a string to the beginning or end of a particular set of
251 ;; lines TPU-edt provides functions to do this.
253 ;; Gold-^ Add a string at BOL in region or buffer
254 ;; Gold-$ Add a string at EOL in region or buffer
256 ;; There is also a TPU-edt interface to the native Emacs string replacement
257 ;; commands. Gold-/ invokes this command. It accepts regular expressions
258 ;; if TPU-edt is in regular expression mode. Given a repeat count, it will
259 ;; perform the replacement without prompting for confirmation.
261 ;; This command replaces empty strings correctly, however, it has its
262 ;; drawbacks. As a native Emacs command, it has a different interface
263 ;; than the emulated TPU commands. Also, it works only in the forward
264 ;; direction, regardless of the current TPU-edt direction.
266 ;;; Todo/Bugs:
268 ;; We shouldn't use vt100 ESC sequences since it is uselessly fighting
269 ;; against function-key-map. Better use real key names.

1115 More extensive documentation on TPU-edt can be found in the `Commentary'
1116 section of tpu-edt.el. This section can be accessed through the standard
1117 Emacs help facility using the `p' option. Once you exit TPU-edt Help, one
1118 of the following key sequences is sure to get you there.
1120 ^h p if you're not yet using TPU-edt
1121 Gold-PF2 p if you're using TPU-edt
1123 Alternatively, fire up Emacs help from the command prompt, with
1125 M-x help-for-help <CR> p <CR>
1127 Where `M-x' might be any of `Gold-KP7', 'Do', or 'ESC-x'.
1129 When you successfully invoke this part of the Emacs help facility, you
1130 will see a buffer named `*Finder*' listing a number of topics. Look for
1131 tpu-edt under `emulations'.
