42;; %% Introduction
43
44;; TPU-edt emulates the popular DEC VMS editor EDT (actually, it emulates
45;; DEC TPU's EDT emulation, hence the name TPU-edt). TPU-edt features the
46;; following TPU/edt functionality:
47
48;; . EDT keypad
49;; . On-line help
50;; . Repeat counts
51;; . Scroll margins
52;; . Learn sequences
53;; . Free cursor mode
54;; . Rectangular cut and paste
55;; . Multiple windows and buffers
56;; . TPU line-mode REPLACE command
57;; . Wild card search and substitution
58;; . Configurable through an initialization file
59;; . History recall of search strings, file names, and commands
60
61;; Please note that TPU-edt does NOT emulate TPU. It emulates TPU's EDT
62;; emulation. Very few TPU line-mode commands are supported.
63
4408bb61 64;; TPU-edt, like its VMS cousin, works on VT-series terminals with DEC
1a4cec85
RS
65;; style keyboards. VT terminal emulators, including xterm with the
66;; appropriate key translations, work just fine too.
67
68;; TPU-edt works with X-windows. This is accomplished through a TPU-edt X
69;; key map. The TPU-edt module tpu-mapper creates this map and stores it
70;; in a file. Tpu-mapper will be run automatically the first time you
71;; invoke the X-windows version of emacs, or you can run it by hand. See
72;; the commentary in tpu-mapper.el for details.
73
74
75;; %% Differences Between TPU-edt and DEC TPU/edt
76
77;; In some cases, Emacs doesn't support text highlighting, so selected
78;; regions are not shown in inverse video. Emacs uses the concept of "the
79;; mark". The mark is set at one end of a selected region; the cursor is
8b8a7f01
GM
80;; at the other. In cases where the selected region cannot be shown in
81;; inverse video an at sign (@) appears in the mode line when mark is set.
82;; The native emacs command ^X^X (Control-X twice) exchanges the cursor
83;; with the mark; this provides a handy way to find the location of the
84;; mark.
1a4cec85
RS
85
86;; In TPU the cursor can be either bound or free. Bound means the cursor
87;; cannot wander outside the text of the file being edited. Free means
88;; the arrow keys can move the cursor past the ends of lines. Free is the
89;; default mode in TPU; bound is the only mode in EDT. Bound is the only
90;; mode in the base version of TPU-edt; optional extensions add an
91;; approximation of free mode, see the commentary in tpu-extras.el for
92;; details.
93
94;; Like TPU, emacs uses multiple buffers. Some buffers are used to hold
95;; files you are editing; other "internal" buffers are used for emacs' own
96;; purposes (like showing you help). Here are some commands for dealing
97;; with buffers.
98
99;; Gold-B moves to next buffer, including internal buffers
100;; Gold-N moves to next buffer containing a file
101;; Gold-M brings up a buffer menu (like TPU "show buffers")
102
103;; Emacs is very fond of throwing up new windows. Dealing with all these
104;; windows can be a little confusing at first, so here are a few commands
105;; to that may help:
106
107;; Gold-Next_Scr moves to the next window on the screen
108;; Gold-Prev_Scr moves to the previous window on the screen
109;; Gold-TAB also moves to the next window on the screen
110
111;; Control-x 1 deletes all but the current window
112;; Control-x 0 deletes the current window
113
114;; Note that the buffers associated with deleted windows still exist!
115
116;; Like TPU, TPU-edt has a "command" function, invoked with Gold-KP7 or
117;; Do. Most of the commands available are emacs commands. Some TPU
118;; commands are available, they are: replace, exit, quit, include, and
119;; Get (unfortunately, "get" is an internal emacs function, so we are
120;; stuck with "Get" - to make life easier, Get is available as Gold-g).
121
122;; TPU-edt supports the recall of commands, file names, and search
123;; strings. The history of strings recalled differs slightly from
124;; TPU/edt, but it is still very convenient.
125
126;; Help is available! The traditional help keys (Help and PF2) display
127;; a small help file showing the default keypad layout, control key
128;; functions, and Gold key functions. Pressing any key inside of help
129;; splits the screen and prints a description of the function of the
4408bb61 130;; pressed key. Gold-PF2 invokes the native emacs help, with its
1a4cec85
RS
131;; zillions of options.
132
133;; Thanks to emacs, TPU-edt has some extensions that may make your life
134;; easier, or at least more interesting. For example, Gold-r toggles
135;; TPU-edt rectangular mode. In rectangular mode, Remove and Insert work
136;; on rectangles. Likewise, Gold-* toggles TPU-edt regular expression
137;; mode. In regular expression mode Find, Find Next, and the line-mode
138;; replace command work with regular expressions. [A regular expression
139;; is a pattern that denotes a set of strings; like VMS wildcards.]
140
141;; Emacs also gives TPU-edt the undo and occur functions. Undo does
142;; what it says; it undoes the last change. Multiple undos in a row
143;; undo multiple changes. For your convenience, undo is available on
144;; Gold-u. Occur shows all the lines containing a specific string in
145;; another window. Moving to that window, and typing ^C^C (Control-C
146;; twice) on a particular line moves you back to the original window
147;; at that line. Occur is on Gold-o.
148
149;; Finally, as you edit, remember that all the power of emacs is at
150;; your disposal. It really is a fantastic tool. You may even want to
151;; take some time and read the emacs tutorial; perhaps not to learn the
152;; native emacs key bindings, but to get a feel for all the things
153;; emacs can do for you. The emacs tutorial is available from the
154;; emacs help function: "Gold-PF2 t"
155
156
157;; %% Starting TPU-edt
158
159;; All you have to do to start TPU-edt, is turn it on. This can be
160;; done from the command line when running emacs.
161
162;; prompt> emacs -f tpu-edt
163
164;; If you've already started emacs, turn on TPU-edt using the tpu-edt
165;; command. First press `M-x' (that's usually `ESC' followed by `x')
166;; and type `tpu-edt' followed by a carriage return.
167
168;; If you like TPU-edt and want to use it all the time, you can start
169;; TPU-edt using the emacs initialization file, .emacs. Simply create
170;; a .emacs file in your home directory containing the line:
171
172;; (tpu-edt)
173
174;; That's all you need to do to start TPU-edt.
175
176
177;; %% Customizing TPU-edt using the Emacs Initialization File
178
179;; The following is a sample emacs initialization file. It shows how to
180;; invoke TPU-edt, and how to customize it.
181
182;; ; .emacs - a sample emacs initialization file
183
184;; ; Turn on TPU-edt
185;; (tpu-edt)
186
187;; ; Set scroll margins 10% (top) and 15% (bottom).
6719bba6 188;; (tpu-set-scroll-margins "10%" "15%")
1a4cec85
RS
189
190;; ; Load the vtxxx terminal control functions.
191;; (load "vt-control" t)
192
193;; ; TPU-edt treats words like EDT; here's how to add word separators.
194;; ; Note that backslash (\) and double quote (") are quoted with '\'.
195;; (tpu-add-word-separators "]\\[-_,.\"=+()'/*#:!&;$")
196
197;; ; Emacs is happy to save files without a final newline; other Unix
198;; ; programs hate that! Here we make sure that files end with newlines.
199;; (setq require-final-newline t)
200
201;; ; Emacs uses Control-s and Control-q. Problems can occur when using
202;; ; emacs on terminals that use these codes for flow control (Xon/Xoff
203;; ; flow control). These lines disable emacs' use of these characters.
204;; (global-unset-key "\C-s")
205;; (global-unset-key "\C-q")
206
207;; ; The emacs universal-argument function is very useful.
208;; ; This line maps universal-argument to Gold-PF1.
209;; (define-key GOLD-SS3-map "P" 'universal-argument) ; Gold-PF1
210
211;; ; Make KP7 move by paragraphs, instead of pages.
212;; (define-key SS3-map "w" 'tpu-paragraph) ; KP7
213
214;; ; Repeat the preceding mappings for X-windows.
215;; (cond
216;; (window-system
217;; (global-set-key [kp_7] 'tpu-paragraph) ; KP7
218;; (define-key GOLD-map [kp_f1] 'universal-argument))) ; GOLD-PF1
219
220;; ; Display the TPU-edt version.
221;; (tpu-version)
222
223
224;; %% Regular Expressions in TPU-edt
225
226;; Gold-* toggles TPU-edt regular expression mode. In regular expression
227;; mode, find, find next, replace, and substitute accept emacs regular
228;; expressions. A complete list of emacs regular expressions can be found
229;; using the emacs "info" command (it's somewhat like the VMS help
230;; command). Try the following sequence of commands:
231
232;; DO info <enter info mode>
233;; m emacs <select the "emacs" topic>
234;; m regexs <select the "regular expression" topic>
235
236;; Type "q" to quit out of info mode.
237
238;; There is a problem in regular expression mode when searching for empty
239;; strings, like beginning-of-line (^) and end-of-line ($). When searching
240;; for these strings, find-next may find the current string, instead of the
241;; next one. This can cause global replace and substitute commands to loop
242;; forever in the same location. For this reason, commands like
243
244;; replace "^" "> " <add "> " to beginning of line>
245;; replace "$" "00711" <add "00711" to end of line>
246
247;; may not work properly.
248
249;; Commands like those above are very useful for adding text to the
250;; beginning or end of lines. They might work on a line-by-line basis, but
251;; go into an infinite loop if the "all" response is specified. If the
252;; goal is to add a string to the beginning or end of a particular set of
253;; lines TPU-edt provides functions to do this.
254
255;; Gold-^ Add a string at BOL in region or buffer
256;; Gold-$ Add a string at EOL in region or buffer
257
258;; There is also a TPU-edt interface to the native emacs string replacement
259;; commands. Gold-/ invokes this command. It accepts regular expressions
260;; if TPU-edt is in regular expression mode. Given a repeat count, it will
261;; perform the replacement without prompting for confirmation.
262
263;; This command replaces empty strings correctly, however, it has its
264;; drawbacks. As a native emacs command, it has a different interface
265;; than the emulated TPU commands. Also, it works only in the forward
266;; direction, regardless of the current TPU-edt direction.

910 More extensive documentation on TPU-edt can be found in the `Commentary'
911 section of tpu-edt.el. This section can be accessed through the standard
912 Emacs help facility using the `p' option. Once you exit TPU-edt Help, one
913 of the following key sequences is sure to get you there.
914
915 ^h p if you're not yet using TPU-edt
916 Gold-PF2 p if you're using TPU-edt
917
918 Alternatively, fire up Emacs help from the command prompt, with
919
920 M-x help-for-help <CR> p <CR>
921
922 Where `M-x' might be any of `Gold-KP7', 'Do', or 'ESC-x'.
923
924 When you successfully invoke this part of the Emacs help facility, you
925 will see a buffer named `*Finder*' listing a number of topics. Look for
926 tpu-edt under `emulations'.
