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

1114 More extensive documentation on TPU-edt can be found in the `Commentary'
1115 section of tpu-edt.el. This section can be accessed through the standard
1116 Emacs help facility using the `p' option. Once you exit TPU-edt Help, one
1117 of the following key sequences is sure to get you there.
1119 ^h p if you're not yet using TPU-edt
1120 Gold-PF2 p if you're using TPU-edt
1122 Alternatively, fire up Emacs help from the command prompt, with
1124 M-x help-for-help <CR> p <CR>
1126 Where `M-x' might be any of `Gold-KP7', 'Do', or 'ESC-x'.
1128 When you successfully invoke this part of the Emacs help facility, you
1129 will see a buffer named `*Finder*' listing a number of topics. Look for
1130 tpu-edt under `emulations'.
