31 ;; %% TPU-edt -- Emacs emulating TPU emulating EDT
36 ;; % Differences Between TPU-edt and DEC TPU/edt
38 ;; % Customizing TPU-edt using the Emacs Initialization File
39 ;; % Regular Expressions in TPU-edt
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:
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
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.
64 ;; TPU-edt, like its VMS cousin, works on VT-series terminals with DEC
65 ;; style keyboards. VT terminal emulators, including xterm with the
66 ;; appropriate key translations, work just fine too.
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.
75 ;; %% Differences Between TPU-edt and DEC TPU/edt
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
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
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
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
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")
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
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
111 ;; Control-x 1 deletes all but the current window
112 ;; Control-x 0 deletes the current window
114 ;; Note that the buffers associated with deleted windows still exist!
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).
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.
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
130 ;; pressed key. Gold-PF2 invokes the native emacs help, with its
131 ;; zillions of options.
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.]
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.
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"
157 ;; %% Starting TPU-edt
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.
162 ;; prompt> emacs -f tpu-edt
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.
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:
174 ;; That's all you need to do to start TPU-edt.
177 ;; %% Customizing TPU-edt using the Emacs Initialization File
179 ;; The following is a sample emacs initialization file. It shows how to
180 ;; invoke TPU-edt, and how to customize it.
182 ;; ; .emacs - a sample emacs initialization file
187 ;; ; Set scroll margins 10% (top) and 15% (bottom).
188 ;; (tpu-set-scroll-margins "10%" "15%")
190 ;; ; Load the vtxxx terminal control functions.
191 ;; (load "vt-control" t)
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 "]\\[-_,.\"=+()'/*#:!&;$")
197 ;; ; Emacs is happy to save files without a final newline; other Unix
198 ;; ; programs hate that! Here we make sure that files end with newlines.
199 ;; (setq require-final-newline t)
201 ;; ; Emacs uses Control-s and Control-q. Problems can occur when using
202 ;; ; emacs on terminals that use these codes for flow control (Xon/Xoff
203 ;; ; flow control). These lines disable emacs' use of these characters.
204 ;; (global-unset-key "\C-s")
205 ;; (global-unset-key "\C-q")
207 ;; ; The emacs universal-argument function is very useful.
208 ;; ; This line maps universal-argument to Gold-PF1.
209 ;; (define-key GOLD-SS3-map "P" 'universal-argument) ; Gold-PF1
211 ;; ; Make KP7 move by paragraphs, instead of pages.
212 ;; (define-key SS3-map "w" 'tpu-paragraph) ; KP7
214 ;; ; Repeat the preceding mappings for X-windows.
217 ;; (global-set-key [kp_7] 'tpu-paragraph) ; KP7
218 ;; (define-key GOLD-map [kp_f1] 'universal-argument))) ; GOLD-PF1
220 ;; ; Display the TPU-edt version.
224 ;; %% Regular Expressions in TPU-edt
226 ;; Gold-* toggles TPU-edt regular expression mode. In regular expression
227 ;; mode, find, find next, replace, and substitute accept emacs regular
228 ;; expressions. A complete list of emacs regular expressions can be found
229 ;; using the emacs "info" command (it's somewhat like the VMS help
230 ;; command). Try the following sequence of commands:
232 ;; DO info <enter info mode>
233 ;; m emacs <select the "emacs" topic>
234 ;; m regexs <select the "regular expression" topic>
236 ;; Type "q" to quit out of info mode.
238 ;; There is a problem in regular expression mode when searching for empty
239 ;; strings, like beginning-of-line (^) and end-of-line ($). 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
244 ;; replace "^" "> " <add "> " to beginning of line>
245 ;; replace "$" "00711" <add "00711" to end of line>
247 ;; may not work properly.
249 ;; Commands like those above are very useful for adding text to the
250 ;; beginning or end of lines. They might work on a line-by-line basis, but
251 ;; go into an infinite loop if the "all" response is specified. If the
252 ;; goal is to add a string to the beginning or end of a particular set of
253 ;; lines TPU-edt provides functions to do this.
255 ;; Gold-^ Add a string at BOL in region or buffer
256 ;; Gold-$ Add a string at EOL in region or buffer
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.
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.
915 ^h p if you're not yet using TPU-edt
916 Gold-PF2 p if you're using TPU-edt
918 Alternatively, fire up Emacs help from the command prompt, with
920 M-x help-for-help <CR> p <CR>
922 Where `M-x' might be any of `Gold-KP7', 'Do', or 'ESC-x'.
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'.
