41 | ||
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 | |
80 | ;; at the other. The letter "M" appears in the mode line when the mark is | |
81 | ;; set. The native emacs command ^X^X (Control-X twice) exchanges the | |
82 | ;; cursor with the mark; this provides a handy way to find the location of | |
83 | ;; the mark. | |
84 | ||
85 | ;; In TPU the cursor can be either bound or free. Bound means the cursor | |
86 | ;; cannot wander outside the text of the file being edited. Free means | |
87 | ;; the arrow keys can move the cursor past the ends of lines. Free is the | |
88 | ;; default mode in TPU; bound is the only mode in EDT. Bound is the only | |
89 | ;; mode in the base version of TPU-edt; optional extensions add an | |
90 | ;; approximation of free mode, see the commentary in tpu-extras.el for | |
91 | ;; details. | |
92 | ||
93 | ;; Like TPU, emacs uses multiple buffers. Some buffers are used to hold | |
94 | ;; files you are editing; other "internal" buffers are used for emacs' own | |
95 | ;; purposes (like showing you help). Here are some commands for dealing | |
96 | ;; with buffers. | |
97 | ||
98 | ;; Gold-B moves to next buffer, including internal buffers | |
99 | ;; Gold-N moves to next buffer containing a file | |
100 | ;; Gold-M brings up a buffer menu (like TPU "show buffers") | |
101 | ||
102 | ;; Emacs is very fond of throwing up new windows. Dealing with all these | |
103 | ;; windows can be a little confusing at first, so here are a few commands | |
104 | ;; to that may help: | |
105 | ||
106 | ;; Gold-Next_Scr moves to the next window on the screen | |
107 | ;; Gold-Prev_Scr moves to the previous window on the screen | |
108 | ;; Gold-TAB also moves to the next window on the screen | |
109 | ||
110 | ;; Control-x 1 deletes all but the current window | |
111 | ;; Control-x 0 deletes the current window | |
112 | ||
113 | ;; Note that the buffers associated with deleted windows still exist! | |
114 | ||
115 | ;; Like TPU, TPU-edt has a "command" function, invoked with Gold-KP7 or | |
116 | ;; Do. Most of the commands available are emacs commands. Some TPU | |
117 | ;; commands are available, they are: replace, exit, quit, include, and | |
118 | ;; Get (unfortunately, "get" is an internal emacs function, so we are | |
119 | ;; stuck with "Get" - to make life easier, Get is available as Gold-g). | |
120 | ||
121 | ;; TPU-edt supports the recall of commands, file names, and search | |
122 | ;; strings. The history of strings recalled differs slightly from | |
123 | ;; TPU/edt, but it is still very convenient. | |
124 | ||
125 | ;; Help is available! The traditional help keys (Help and PF2) display | |
126 | ;; a small help file showing the default keypad layout, control key | |
127 | ;; functions, and Gold key functions. Pressing any key inside of help | |
128 | ;; splits the screen and prints a description of the function of the | |
4408bb61 | 129 | ;; pressed key. Gold-PF2 invokes the native emacs help, with its |
1a4cec85 RS |
130 | ;; zillions of options. |
131 | ||
132 | ;; Thanks to emacs, TPU-edt has some extensions that may make your life | |
133 | ;; easier, or at least more interesting. For example, Gold-r toggles | |
134 | ;; TPU-edt rectangular mode. In rectangular mode, Remove and Insert work | |
135 | ;; on rectangles. Likewise, Gold-* toggles TPU-edt regular expression | |
136 | ;; mode. In regular expression mode Find, Find Next, and the line-mode | |
137 | ;; replace command work with regular expressions. [A regular expression | |
138 | ;; is a pattern that denotes a set of strings; like VMS wildcards.] | |
139 | ||
140 | ;; Emacs also gives TPU-edt the undo and occur functions. Undo does | |
141 | ;; what it says; it undoes the last change. Multiple undos in a row | |
142 | ;; undo multiple changes. For your convenience, undo is available on | |
143 | ;; Gold-u. Occur shows all the lines containing a specific string in | |
144 | ;; another window. Moving to that window, and typing ^C^C (Control-C | |
145 | ;; twice) on a particular line moves you back to the original window | |
146 | ;; at that line. Occur is on Gold-o. | |
147 | ||
148 | ;; Finally, as you edit, remember that all the power of emacs is at | |
149 | ;; your disposal. It really is a fantastic tool. You may even want to | |
150 | ;; take some time and read the emacs tutorial; perhaps not to learn the | |
151 | ;; native emacs key bindings, but to get a feel for all the things | |
152 | ;; emacs can do for you. The emacs tutorial is available from the | |
153 | ;; emacs help function: "Gold-PF2 t" | |
154 | ||
155 | ||
156 | ;; %% Starting TPU-edt | |
157 | ||
158 | ;; All you have to do to start TPU-edt, is turn it on. This can be | |
159 | ;; done from the command line when running emacs. | |
160 | ||
161 | ;; prompt> emacs -f tpu-edt | |
162 | ||
163 | ;; If you've already started emacs, turn on TPU-edt using the tpu-edt | |
164 | ;; command. First press `M-x' (that's usually `ESC' followed by `x') | |
165 | ;; and type `tpu-edt' followed by a carriage return. | |
166 | ||
167 | ;; If you like TPU-edt and want to use it all the time, you can start | |
168 | ;; TPU-edt using the emacs initialization file, .emacs. Simply create | |
169 | ;; a .emacs file in your home directory containing the line: | |
170 | ||
171 | ;; (tpu-edt) | |
172 | ||
173 | ;; That's all you need to do to start TPU-edt. | |
174 | ||
175 | ||
176 | ;; %% Customizing TPU-edt using the Emacs Initialization File | |
177 | ||
178 | ;; The following is a sample emacs initialization file. It shows how to | |
179 | ;; invoke TPU-edt, and how to customize it. | |
180 | ||
181 | ;; ; .emacs - a sample emacs initialization file | |
182 | ||
183 | ;; ; Turn on TPU-edt | |
184 | ;; (tpu-edt) | |
185 | ||
186 | ;; ; Set scroll margins 10% (top) and 15% (bottom). | |
187 | ;; (tpu-set-scroll-margins "10%" "15%") | |
188 | ||
189 | ;; ; Load the vtxxx terminal control functions. | |
190 | ;; (load "vt-control" t) | |
191 | ||
192 | ;; ; TPU-edt treats words like EDT; here's how to add word separators. | |
193 | ;; ; Note that backslash (\) and double quote (") are quoted with '\'. | |
194 | ;; (tpu-add-word-separators "]\\[-_,.\"=+()'/*#:!&;$") | |
195 | ||
196 | ;; ; Emacs is happy to save files without a final newline; other Unix | |
197 | ;; ; programs hate that! Here we make sure that files end with newlines. | |
198 | ;; (setq require-final-newline t) | |
199 | ||
200 | ;; ; Emacs uses Control-s and Control-q. Problems can occur when using | |
201 | ;; ; emacs on terminals that use these codes for flow control (Xon/Xoff | |
202 | ;; ; flow control). These lines disable emacs' use of these characters. | |
203 | ;; (global-unset-key "\C-s") | |
204 | ;; (global-unset-key "\C-q") | |
205 | ||
206 | ;; ; The emacs universal-argument function is very useful. | |
207 | ;; ; This line maps universal-argument to Gold-PF1. | |
208 | ;; (define-key GOLD-SS3-map "P" 'universal-argument) ; Gold-PF1 | |
209 | ||
210 | ;; ; Make KP7 move by paragraphs, instead of pages. | |
211 | ;; (define-key SS3-map "w" 'tpu-paragraph) ; KP7 | |
212 | ||
213 | ;; ; Repeat the preceding mappings for X-windows. | |
214 | ;; (cond | |
215 | ;; (window-system | |
216 | ;; (global-set-key [kp_7] 'tpu-paragraph) ; KP7 | |
217 | ;; (define-key GOLD-map [kp_f1] 'universal-argument))) ; GOLD-PF1 | |
218 | ||
219 | ;; ; Display the TPU-edt version. | |
220 | ;; (tpu-version) | |
221 | ||
222 | ||
223 | ;; %% Regular Expressions in TPU-edt | |
224 | ||
225 | ;; Gold-* toggles TPU-edt regular expression mode. In regular expression | |
226 | ;; mode, find, find next, replace, and substitute accept emacs regular | |
227 | ;; expressions. A complete list of emacs regular expressions can be found | |
228 | ;; using the emacs "info" command (it's somewhat like the VMS help | |
229 | ;; command). Try the following sequence of commands: | |
230 | ||
231 | ;; DO info <enter info mode> | |
232 | ;; m emacs <select the "emacs" topic> | |
233 | ;; m regexs <select the "regular expression" topic> | |
234 | ||
235 | ;; Type "q" to quit out of info mode. | |
236 | ||
237 | ;; There is a problem in regular expression mode when searching for empty | |
238 | ;; strings, like beginning-of-line (^) and end-of-line ($). When searching | |
239 | ;; for these strings, find-next may find the current string, instead of the | |
240 | ;; next one. This can cause global replace and substitute commands to loop | |
241 | ;; forever in the same location. For this reason, commands like | |
242 | ||
243 | ;; replace "^" "> " <add "> " to beginning of line> | |
244 | ;; replace "$" "00711" <add "00711" to end of line> | |
245 | ||
246 | ;; may not work properly. | |
247 | ||
248 | ;; Commands like those above are very useful for adding text to the | |
249 | ;; beginning or end of lines. They might work on a line-by-line basis, but | |
250 | ;; go into an infinite loop if the "all" response is specified. If the | |
251 | ;; goal is to add a string to the beginning or end of a particular set of | |
252 | ;; lines TPU-edt provides functions to do this. | |
253 | ||
254 | ;; Gold-^ Add a string at BOL in region or buffer | |
255 | ;; Gold-$ Add a string at EOL in region or buffer | |
256 | ||
257 | ;; There is also a TPU-edt interface to the native emacs string replacement | |
258 | ;; commands. Gold-/ invokes this command. It accepts regular expressions | |
259 | ;; if TPU-edt is in regular expression mode. Given a repeat count, it will | |
260 | ;; perform the replacement without prompting for confirmation. | |
261 | ||
262 | ;; This command replaces empty strings correctly, however, it has its | |
263 | ;; drawbacks. As a native emacs command, it has a different interface | |
264 | ;; than the emulated TPU commands. Also, it works only in the forward | |
265 | ;; direction, regardless of the current TPU-edt direction. | |

917 | More extensive documentation on TPU-edt can be found in the `Commentary' | |
918 | section of tpu-edt.el. This section can be accessed through the standard | |
919 | Emacs help facility using the `p' option. Once you exit TPU-edt Help, one | |
920 | of the following key sequences is sure to get you there. | |
921 | ||
922 | ^h p if you're not yet using TPU-edt | |
923 | Gold-PF2 p if you're using TPU-edt | |
924 | ||
925 | Alternatively, fire up Emacs help from the command prompt, with | |
926 | ||
927 | M-x help-for-help <CR> p <CR> | |
928 | ||
929 | Where `M-x' might be any of `Gold-KP7', 'Do', or 'ESC-x'. | |
930 | ||
931 | When you successfully invoke this part of the Emacs help facility, you | |
932 | will see a buffer named `*Finder*' listing a number of topics. Look for | |
933 | tpu-edt under `emulations'. | |
