41 | ;; %% Introduction | |
42 | ||
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: | |
46 | ||
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 | |
59 | ||
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. | |
62 | ||
4408bb61 | 63 | ;; TPU-edt, like its VMS cousin, works on VT-series terminals with DEC |
1a4cec85 RS |
64 | ;; style keyboards. VT terminal emulators, including xterm with the |
65 | ;; appropriate key translations, work just fine too. | |
66 | ||
88a83b17 SM |
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. | |
1a4cec85 RS |

72 | ||
73 | ;; %% Differences Between TPU-edt and DEC TPU/edt | |
74 | ||
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 | |
8b8a7f01 GM |
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. | |
db7552d5 | 80 | ;; The native Emacs command ^X^X (Control-X twice) exchanges the cursor |
8b8a7f01 GM |
81 | ;; with the mark; this provides a handy way to find the location of the |
82 | ;; mark. | |
1a4cec85 RS |
83 | |
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. | |
91 | ||
db7552d5 | 92 | ;; Like TPU, Emacs uses multiple buffers. Some buffers are used to hold |
44e97401 | 93 | ;; files you are editing; other "internal" buffers are used for Emacs's own |
1a4cec85 RS |
94 | ;; purposes (like showing you help). Here are some commands for dealing |
95 | ;; with buffers. | |
96 | ||
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") | |
100 | ||
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: | |
104 | ||
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 | |
108 | ||
109 | ;; Control-x 1 deletes all but the current window | |
110 | ;; Control-x 0 deletes the current window | |
111 | ||
112 | ;; Note that the buffers associated with deleted windows still exist! | |
113 | ||
114 | ;; Like TPU, TPU-edt has a "command" function, invoked with Gold-KP7 or | |
db7552d5 | 115 | ;; Do. Most of the commands available are Emacs commands. Some TPU |
1a4cec85 | 116 | ;; commands are available, they are: replace, exit, quit, include, and |
db7552d5 | 117 | ;; Get (unfortunately, "get" is an internal Emacs function, so we are |
1a4cec85 RS |
118 | ;; stuck with "Get" - to make life easier, Get is available as Gold-g). |
119 | ||
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. | |
123 | ||
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 | |
db7552d5 | 128 | ;; pressed key. Gold-PF2 invokes the native Emacs help, with its |
1a4cec85 RS |
129 | ;; zillions of options. |
130 | ||
db7552d5 | 131 | ;; Thanks to Emacs, TPU-edt has some extensions that may make your life |
1a4cec85 RS |
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.] | |
138 | ||
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. | |
146 | ||
db7552d5 | 147 | ;; Finally, as you edit, remember that all the power of Emacs is at |
1a4cec85 | 148 | ;; your disposal. It really is a fantastic tool. You may even want to |
db7552d5 SM |
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" | |
1a4cec85 RS |
153 | |
154 | ||
155 | ;; %% Starting TPU-edt | |
156 | ||
157 | ;; All you have to do to start TPU-edt, is turn it on. This can be | |
db7552d5 | 158 | ;; done from the command line when running Emacs. |
1a4cec85 RS |
159 | |
160 | ;; prompt> emacs -f tpu-edt | |
161 | ||
db7552d5 | 162 | ;; If you've already started Emacs, turn on TPU-edt using the tpu-edt |
1a4cec85 RS |
163 | ;; command. First press `M-x' (that's usually `ESC' followed by `x') |
164 | ;; and type `tpu-edt' followed by a carriage return. | |
165 | ||
166 | ;; If you like TPU-edt and want to use it all the time, you can start | |
865fe16f CY |
167 | ;; TPU-edt using the Emacs initialization file, .emacs. Simply add |
168 | ;; the following line to your init file: | |
1a4cec85 RS |
169 | |
170 | ;; (tpu-edt) | |
171 | ||
172 | ;; That's all you need to do to start TPU-edt. | |
173 | ||
174 | ||
175 | ;; %% Customizing TPU-edt using the Emacs Initialization File | |
176 | ||
db7552d5 | 177 | ;; The following is a sample Emacs initialization file. It shows how to |
1a4cec85 RS |
178 | ;; invoke TPU-edt, and how to customize it. |

222 | ;; %% Regular Expressions in TPU-edt | |
223 | ||
224 | ;; Gold-* toggles TPU-edt regular expression mode. In regular expression | |
db7552d5 SM |
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 | |
1a4cec85 RS |
228 | ;; command). Try the following sequence of commands: |
229 | ||
230 | ;; DO info <enter info mode> | |
231 | ;; m emacs <select the "emacs" topic> | |
232 | ;; m regexs <select the "regular expression" topic> | |
233 | ||
234 | ;; Type "q" to quit out of info mode. | |
235 | ||
236 | ;; There is a problem in regular expression mode when searching for empty | |
237 | ;; strings, like beginning-of-line (^) and end-of-line ($). When searching | |
238 | ;; for these strings, find-next may find the current string, instead of the | |
239 | ;; next one. This can cause global replace and substitute commands to loop | |
240 | ;; forever in the same location. For this reason, commands like | |
241 | ||
242 | ;; replace "^" "> " <add "> " to beginning of line> | |
243 | ;; replace "$" "00711" <add "00711" to end of line> | |
244 | ||
245 | ;; may not work properly. | |
246 | ||
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. | |
252 | ||
253 | ;; Gold-^ Add a string at BOL in region or buffer | |
254 | ;; Gold-$ Add a string at EOL in region or buffer | |
255 | ||
db7552d5 | 256 | ;; There is also a TPU-edt interface to the native Emacs string replacement |
1a4cec85 RS |
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. | |
260 | ||
261 | ;; This command replaces empty strings correctly, however, it has its | |
db7552d5 | 262 | ;; drawbacks. As a native Emacs command, it has a different interface |
1a4cec85 RS |
263 | ;; than the emulated TPU commands. Also, it works only in the forward |
264 | ;; direction, regardless of the current TPU-edt direction. | |

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. | |
1119 | ||
1120 | ^h p if you're not yet using TPU-edt | |
1121 | Gold-PF2 p if you're using TPU-edt | |
1122 | ||
1123 | Alternatively, fire up Emacs help from the command prompt, with | |
1124 | ||
1125 | M-x help-for-help <CR> p <CR> | |
1126 | ||
1127 | Where `M-x' might be any of `Gold-KP7', 'Do', or 'ESC-x'. | |
1128 | ||
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'. | |
