49 | ;; %% Introduction | |
50 | ||
51 | ;; TPU-edt is based on tpu.el by Jeff Kowalski. TPU-edt endeavors | |
52 | ;; to be even more like TPU's EDT emulation than the original tpu.el. | |
53 | ;; Considerable effort has been expended to that end. Still, emacs | |
54 | ;; is emacs and there are differences between TPU-edt and the real | |
55 | ;; thing. Please read the "Differences Between TPU-edt and the Real | |
56 | ;; Thing" and "Starting TPU-edt" sections before running TPU-edt. | |
57 | ||
58 | ||
59 | ;; %% Terminal Support | |
60 | ||
61 | ;; TPU-edt, like it's VMS cousin, works on VT-series terminals with | |
62 | ;; DEC style keyboards. VT terminal emulators, including xterm with | |
63 | ;; the appropriate key translations, work just fine too. | |
64 | ||
65 | ||
66 | ;; %% X-windows Support | |
67 | ||
68 | ;; Starting with version 19 of emacs, TPU-edt works with X-windows. | |
69 | ;; This is accomplished through a TPU-edt X keymap. The emacs lisp | |
70 | ;; program tpu-mapper.el creates this map and stores it in a file. | |
71 | ;; Tpu-mapper will be run automatically the first time you invoke | |
72 | ;; the X-windows version of emacs, or you can run it by hand. See | |
73 | ;; the commentary in tpu-mapper.el for details. | |
74 | ||
75 | ||
76 | ;; %% Differences Between TPU-edt and the Real Thing (not Coke (r)) | |
77 | ||
78 | ;; Emacs (version 18.58) doesn't support text highlighting, so selected | |
79 | ;; regions are not shown in inverse video. Emacs uses the concept of | |
80 | ;; "the mark". The mark is set at one end of a selected region; the | |
81 | ;; cursor is at the other. The letter "M" appears in the mode line | |
82 | ;; when the mark is set. The native emacs command ^X^X (Control-X | |
83 | ;; twice) exchanges the cursor with the mark; this provides a handy | |
84 | ;; way to find the location of the mark. | |
85 | ||
86 | ;; In TPU the cursor can be either bound or free. Bound means the | |
87 | ;; cursor cannot wander outside the text of the file being edited. | |
88 | ;; Free means the arrow keys can move the cursor past the ends of | |
89 | ;; lines. Free is the default mode in TPU; bound is the only mode | |
90 | ;; in EDT. Bound is the only mode in the base version of TPU-edt; | |
91 | ;; optional extensions add an approximation of free mode. | |
92 | ||
93 | ;; Like TPU, emacs uses multiple buffers. Some buffers are used to | |
94 | ;; hold files you are editing; other "internal" buffers are used for | |
95 | ;; emacs' own purposes (like showing you help). Here are some commands | |
96 | ;; for dealing 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 | |
103 | ;; these windows can be a little confusing at first, so here are a few | |
104 | ;; commands 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 | ;; Support for recall of commands, file names, and search strings was | |
122 | ;; added to emacs in version 19. For version 18 of emacs, optional | |
123 | ;; extensions are available to add this recall capability (see "Optional | |
124 | ;; TPU-edt Extensions" below). The history of strings recalled in both | |
125 | ;; versions of emacs differs slightly from TPU/edt, but it is still very | |
126 | ;; convenient. | |
127 | ||
128 | ;; Help is available! The traditional help keys (Help and PF2) display | |
129 | ;; a three page help file showing the default keypad layout, control key | |
130 | ;; functions, and Gold key functions. Pressing any key inside of help | |
131 | ;; splits the screen and prints a description of the function of the | |
132 | ;; pressed key. Gold-PF2 invokes the native emacs help, with it's | |
133 | ;; zillions of options. Gold-Help shows all the current key bindings. | |
134 | ||
135 | ;; Thanks to emacs, TPU-edt has some extensions that may make your life | |
136 | ;; easier, or at least more interesting. For example, Gold-r toggles | |
137 | ;; TPU-edt rectangular mode. In rectangular mode, Remove and Insert work | |
138 | ;; on rectangles. Likewise, Gold-* toggles TPU-edt regular expression | |
139 | ;; mode. In regular expression mode Find, Find Next, and the line-mode | |
140 | ;; replace command work with regular expressions. [A regular expression | |
141 | ;; is a pattern that denotes a set of strings; like VMS wildcards.] | |
142 | ||
143 | ;; Emacs also gives TPU-edt the undo and occur functions. Undo does | |
144 | ;; what it says; it undoes the last change. Multiple undos in a row | |
145 | ;; undo multiple changes. For your convenience, undo is available on | |
146 | ;; Gold-u. Occur shows all the lines containing a specific string in | |
147 | ;; another window. Moving to that window, and typing ^C^C (Control-C | |
148 | ;; twice) on a particular line moves you back to the original window | |
149 | ;; at that line. Occur is on Gold-o. | |
150 | ||
151 | ;; Finally, as you edit, remember that all the power of emacs is at | |
152 | ;; your disposal. It really is a fantastic tool. You may even want to | |
153 | ;; take some time and read the emacs tutorial; perhaps not to learn the | |
154 | ;; native emacs key bindings, but to get a feel for all the things | |
155 | ;; emacs can do for you. The emacs tutorial is available from the | |
156 | ;; emacs help function: "Gold-PF2 t" | |
157 | ||
158 | ||
159 | ;; %% Starting TPU-edt | |
160 | ||
161 | ;; In order to use TPU-edt, the TPU-edt editor definitions, contained | |
162 | ;; in tpu-edt.el, need to be loaded when emacs is run. This can be | |
163 | ;; done in a couple of ways. The first is by explicitly requesting | |
164 | ;; loading of the TPU-edt emacs definition file on the command line: | |
165 | ||
166 | ;; prompt> emacs -l /path/to/definitions/tpu-edt.el | |
167 | ||
168 | ;; If TPU-edt is installed on your system, that is, if tpu-edt.el is in | |
169 | ;; a directory like /usr/local/emacs/lisp, along with dozens of other | |
170 | ;; .el files, you should be able to use the command: | |
171 | ||
172 | ;; prompt> emacs -l tpu-edt | |
173 | ||
174 | ;; If you like TPU-edt and want to use it all the time, you can load | |
175 | ;; the TPU-edt definitions using the emacs initialization file, .emacs. | |
176 | ;; Simply create a .emacs file in your home directory containing the | |
177 | ;; line: | |
178 | ||
179 | ;; (load "/path/to/definitions/tpu-edt") | |
180 | ||
181 | ;; or, if (as above) TPU-edt is installed on your system: | |
182 | ||
183 | ;; (load "tpu-edt") | |
184 | ||
185 | ;; Once TPU-edt has been loaded, you will be using an editor with the | |
186 | ;; interface shown in the next section (A section that is suitable for | |
187 | ;; cutting out of this document and pasting next to your terminal!). | |

254 | ;; %% Optional TPU-edt Extensions | |
255 | ||
256 | ;; Several optional packages have been included in this distribution | |
257 | ;; of TPU-edt. The following is a brief description of each package. | |
258 | ;; See the {package}.el file for more detailed information and usage | |
259 | ;; instructions. | |
260 | ||
261 | ;; tpu-extras - TPU/edt scroll margins and free cursor mode. | |
262 | ;; tpu-recall - String, file name, and command history. | |
263 | ;; vt-control - VTxxx terminal width and keypad controls. | |
264 | ||
265 | ;; Packages are normally loaded from the emacs initialization file | |
266 | ;; (discussed below). If a package is not installed in the emacs | |
267 | ;; lisp directory, it can be loaded by specifying the complete path | |
268 | ;; to the package file. However, it is preferable to modify the | |
269 | ;; emacs load-path variable to include the directory where packages | |
270 | ;; are stored. This way, packages can be loaded by name, just as if | |
271 | ;; they were installed. The first part of the sample .emacs file | |
272 | ;; below shows how to make such a modification. | |
273 | ||
274 | ||
275 | ;; %% Customizing TPU-edt using the Emacs Initialization File | |
276 | ||
277 | ;; .emacs - a sample emacs initialization file | |

283 | ;; If TPU-edt is not installed in a standard emacs directory, the load-path | |
284 | ;; should be updated to include the directory where the TPU-edt files are | |
285 | ;; stored. Modify and un-comment the following section if TPU-ed is not | |
286 | ;; installed on your system - be sure to leave the double quotes! | |
287 | ||

390 | ;; Astute emacs hackers will realize that on systems where TPU-edt is | |

400 | ;; %% Compiling TPU-edt | |
401 | ||
402 | ;; It is not necessary to compile (byte-compile in emacs parlance) | |
403 | ;; TPU-edt to use it. However, byte-compiled code loads and runs | |
404 | ;; faster, and takes up less memory when loaded. To byte compile | |
405 | ;; TPU-edt, use the following command. | |
406 | ||
407 | ;; emacs -batch -f batch-byte-compile tpu-edt.el | |
408 | ||
409 | ;; This will produce a file named tpu-edt.elc. This new file can be | |
410 | ;; used in place of the original tpu-edt.el file. In commands where | |
411 | ;; the file type is not specified, emacs always attempts to use the | |
412 | ;; byte-compiled version before resorting to the source. | |
413 | ||
414 | ||
415 | ;; %% Regular expressions in TPU-edt | |
416 | ||
417 | ;; Gold-* toggles TPU-edt regular expression mode. In regular expression | |
418 | ;; mode, find, find next, replace, and substitute accept emacs regular | |
419 | ;; expressions. A complete list of emacs regular expressions can be | |
420 | ;; found using the emacs "info" command (it's somewhat like the VMS help | |
421 | ;; command). Try the following sequence of commands: | |
422 | ||
423 | ;; DO info <enter info mode> | |
424 | ;; m regex <select the "regular expression" topic> | |
425 | ;; m directives <select the "directives" topic> | |
426 | ||
427 | ;; Type "q" to quit out of info mode. | |
428 | ||
429 | ;; There is a problem in regular expression mode when searching for | |
430 | ;; empty strings, like beginning-of-line (^) and end-of-line ($). | |
431 | ;; When searching for these strings, find-next may find the current | |
432 | ;; string, instead of the next one. This can cause global replace and | |
433 | ;; substitute commands to loop forever in the same location. For this | |
434 | ;; reason, commands like | |
435 | ||
436 | ;; replace "^" "> " <add "> " to beginning of line> | |
437 | ;; replace "$" "00711" <add "00711" to end of line> | |
438 | ||
439 | ;; may not work properly. | |
440 | ||
441 | ;; Commands like those above are very useful for adding text to the | |
442 | ;; beginning or end of lines. They might work on a line-by-line basis, | |
443 | ;; but go into an infinite loop if the "all" response is specified. If | |
444 | ;; the goal is to add a string to the beginning or end of a particular | |
445 | ;; set of lines TPU-edt provides functions to do this. | |
446 | ||
447 | ;; Gold-^ Add a string at BOL in region or buffer | |
448 | ;; Gold-$ Add a string at EOL in region or buffer | |
449 | ||
450 | ;; There is also a TPU-edt interface to the native emacs string | |
451 | ;; replacement commands. Gold-/ invokes this command. It accepts | |
452 | ;; regular expressions if TPU-edt is in regular expression mode. Given | |
453 | ;; a repeat count, it will perform the replacement without prompting | |
454 | ;; for confirmation. | |
455 | ||
456 | ;; This command replaces empty strings correctly, however, it has its | |
457 | ;; drawbacks. As a native emacs command, it has a different interface | |
458 | ;; than the emulated TPU commands. Also, it works only in the forward | |
459 | ;; direction, regardless of the current TPU-edt direction. | |
