33 | ;; Viper is a full-featured Vi emulator for Emacs 19. It emulates and | |
34 | ;; improves upon the standard features of Vi and, at the same time, allows | |
35 | ;; full access to all Emacs facilities. Viper supports multiple undo, | |
36 | ;; file name completion, command, file, and search history and it extends | |
37 | ;; Vi in many other ways. Viper is highly customizable through the various | |
38 | ;; hooks, user variables, and keymaps. It is implemented as a collection | |
39 | ;; of minor modes and it is designed to provide full access to all Emacs | |
40 | ;; major and minor modes. | |
41 | ;; | |
42 | ;;; History | |
43 | ;; | |
44 | ;; Viper is a new name for a package formerly known as VIP-19, | |
45 | ;; which was a successor of VIP version 3.5 by Masahiko Sato | |
46 | ;; <ms@sail.stanford.edu> and VIP version 4.2 by Aamod Sane | |
47 | ;; <sane@cs.uiuc.edu>. Some ideas from vip 4.4.2 by Aamod Sane | |
48 | ;; were also shamelessly plagiarized. | |
49 | ;; | |
50 | ;; Viper maintains some degree of compatibility with these older | |
51 | ;; packages. See the documentation for customization. | |
52 | ;; | |
53 | ;; The main difference between Viper and these older packages are: | |
54 | ;; | |
55 | ;; 1. Viper emulates Vi at several levels, from almost complete conformity | |
56 | ;; to a rather loose Vi-compliance. | |
57 | ;; | |
58 | ;; 2. Viper provides full access to all major and minor modes of Emacs | |
59 | ;; without the need to type extra keys. | |
60 | ;; The older versions of VIP (and other Vi emulators) do not work with | |
61 | ;; some major and minor modes. | |
62 | ;; | |
63 | ;; 3. Viper supports vi-style undo. | |
64 | ;; | |
65 | ;; 4. Viper fully emulates (and improves upon) vi's replacement mode. | |
66 | ;; | |
67 | ;; 5. Viper has a better interface to ex, including command, variable, and | |
68 | ;; file name completion. | |
69 | ;; | |
70 | ;; 6. Viper uses native Emacs history and completion features; it doesn't | |
71 | ;; rely on other packages (such as gmhist.el and completer.el) to provide | |
72 | ;; these features. | |
73 | ;; | |
74 | ;; 7. Viper supports Vi-style editing in the minibuffer, by allowing the | |
75 | ;; user to switch from Insert state to Vi state to Replace state, etc. | |
76 | ;; | |
77 | ;; 8. Viper keeps history of recently inserted pieces of text and recently | |
78 | ;; executed Vi-style destructive commands, such as `i', `d', etc. | |
79 | ;; These pieces of text can be inserted in later insertion commands; | |
80 | ;; the previous destructive commands can be re-executed. | |
81 | ;; | |
82 | ;; 9. Viper has Vi-style keyboard macros, which enhances the similar | |
83 | ;; facility in the original Vi. | |
84 | ;; First, one can execute any Emacs command while defining a | |
85 | ;; macro, not just the Vi commands. Second, macros are defined in a | |
86 | ;; WYSYWYG mode, using an interface to Emacs' WYSIWYG style of defining | |
87 | ;; macros. Third, in Viper, one can define macros that are specific to | |
88 | ;; a given buffer, a given major mode, or macros defined for all buffers. | |
89 | ;; The same macro name can have several different definitions: | |
90 | ;; one global, several definitions for various major modes, and | |
91 | ;; definitions for specific buffers. | |
d63a37ea | 92 | ;; Buffer-specific definitions override mode-specific |
6c2e12f4 KH |
93 | ;; definitions, which, in turn, override global definitions. |

108 | ;; | |
109 | ;;; Notes: | |
110 | ;; | |
111 | ;; 1. Major modes. | |
112 | ;; In most cases, Viper handles major modes correctly, i.e., they come up | |
113 | ;; in the right state (either vi-state or emacs-state). For instance, text | |
114 | ;; files come up in vi-state, while, say, Dired appears in emacs-state by | |
115 | ;; default. | |
116 | ;; However, some modes do not appear in the right mode in the beginning, | |
117 | ;; usually because they neglect to follow Emacs conventions (e.g., they don't | |
d695b318 | 118 | ;; use kill-all-local-variables when they start). Some major modes |
6c2e12f4 KH |
119 | ;; may fail to come up in emacs-state if they call hooks, such as |
120 | ;; text-hook, for no good reason. | |
121 | ;; | |
122 | ;; As an immediate solution, you can hit C-z to bring about the right mode. | |
123 | ;; An interim solution is to add an appropriate hook to the mode like this: | |
124 | ;; | |
125 | ;; (add-hook 'your-favorite-mode 'viper-mode) | |
126 | ;; or | |
127 | ;; (add-hook 'your-favorite-mode 'vip-change-state-to-emacs) | |
128 | ;; | |
129 | ;; whichever applies. The right thing to do, however, is to complain to the | |
130 | ;; author of the respective package. (Sometimes they also neglect to equip | |
131 | ;; their modes with hooks, which is one more reason for complaining.) | |
132 | ;; | |
133 | ;; 2. Keymap handling | |
134 | ;; Because Emacs 19 has an elegant mechanism for turning minor mode keymaps | |
135 | ;; on and off, implementation of Viper has been greatly simplified. Viper | |
136 | ;; has several minor modes. | |
137 | ;; | |
138 | ;; Viper's Vi state consists of seven minor modes: | |
139 | ;; | |
140 | ;; vip-vi-intercept-minor-mode | |
141 | ;; vip-vi-local-user-minor-mode | |
142 | ;; vip-vi-global-user-minor-mode | |
143 | ;; vip-vi-kbd-minor-mode | |
144 | ;; vip-vi-state-modifier-minor-mode | |
145 | ;; vip-vi-diehard-minor-mode | |
146 | ;; vip-vi-basic-minor-mode | |
147 | ;; | |
148 | ;; Bindings done to the keymap of the first mode overshadow those done to | |
149 | ;; the second, which, in turn, overshadows those done to the third, etc. | |
150 | ;; | |
151 | ;; The last vip-vi-basic-minor-mode contains most of the usual Vi bindings | |
152 | ;; in its edit mode. This mode provides access to all Emacs facilities. | |
153 | ;; Novice users, however, may want to set their vip-expert-level to 1 | |
154 | ;; in their .vip file. This will enable vip-vi-diehard-minor-mode. This | |
155 | ;; minor mode's bindings make Viper simulate the usual Vi very closely. | |
156 | ;; For instance, C-c will not have its standard Emacs binding | |
157 | ;; and so many of the goodies of Emacs are not available. | |
158 | ;; | |
d63a37ea KH |
159 | ;; A skilled user should set vip-expert-level to at least 3. This will |
160 | ;; enable `C-c' and many Emacs facilities will become available. | |
6c2e12f4 KH |
161 | ;; In this case, vip-vi-diehard-minor-mode is inactive. |
162 | ;; | |
163 | ;; Viper gurus should have at least | |
164 | ;; (setq vip-expert-level 4) | |
165 | ;; in their ~/.vip files. This will unsuppress all Emacs keys that are not | |
166 | ;; essential for VI-style editing. | |
167 | ;; Pick-and-choose users may want to put | |
168 | ;; (setq vip-expert-level 5) | |
169 | ;; in ~/.vip. Viper will then leave it up to the user to set the variables | |
170 | ;; vip-want-* See vip-set-expert-level for details. | |
171 | ;; | |
172 | ;; The very first minor mode, vip-vi-intercept-minor-mode, is of no | |
173 | ;; concern for the user. It is needed to bind Viper's vital keys, such as | |
174 | ;; ESC and C-z. | |
175 | ;; | |
176 | ;; The second mode, vip-vi-local-user-minor-mode, usually has an | |
177 | ;; empty keymap. However, the user can set bindings in this keymap, which | |
178 | ;; will overshadow the corresponding bindings in the other two minor | |
179 | ;; modes. This is useful, for example, for setting up ZZ in gnus, | |
180 | ;; rmail, mh-e, etc., to send message instead of saving it in a file. | |
181 | ;; Likewise, in Dired mode, you may want to bind ZN and ZP to commands | |
182 | ;; that would visit the next or the previous file in the Dired buffer. | |
183 | ;; Setting local keys is tricky, so don't do it directly. Instead, use | |
184 | ;; vip-add-local-keys function (see its doc). | |
185 | ;; | |
186 | ;; The third minor mode, vip-vi-global-user-minor-mode, is also intended | |
187 | ;; for the users but, unlike vip-vi-local-user-minor-mode, its key | |
188 | ;; bindings are seen in all Viper buffers. This mode keys can be done | |
189 | ;; with define-key command. | |
190 | ;; | |
191 | ;; The fourth minor mode, vip-vi-kbd-minor-mode, is used by keyboard | |
192 | ;; macros. Users are NOT supposed to modify this keymap directly. | |
193 | ;; | |
194 | ;; The fifth mode, vip-vi-state-modifier-minor-mode, can be used to set | |
195 | ;; key bindings that are visible in some major modes but not in others. | |
196 | ;; | |
197 | ;; Users are allowed to modify keymaps that belong to | |
198 | ;; vip-vi-local-user-minor-mode, vip-vi-global-user-minor-mode, | |
199 | ;; and vip-vi-state-modifier-minor-mode only. | |
200 | ;; | |
201 | ;; Viper's Insert state also has seven minor modes: | |
202 | ;; | |
203 | ;; vip-insert-intercept-minor-mode | |
204 | ;; vip-insert-local-user-minor-mode | |
205 | ;; vip-insert-global-user-minor-mode | |
206 | ;; vip-insert-kbd-minor-mode | |
207 | ;; vip-insert-state-modifier-minor-mode | |
208 | ;; vip-insert-diehard-minor-mode | |
209 | ;; vip-insert-basic-minor-mode | |
210 | ;; | |
211 | ;; As with VI's editing modes, the first mode, vip-insert-intercept-minor-mode | |
212 | ;; is used to bind vital keys that are not to be changed by the user. | |
213 | ;; | |
214 | ;; The next mode, vip-insert-local-user-minor-mode, is used to customize | |
215 | ;; bindings in the insert state of Viper. The third mode, | |
216 | ;; vip-insert-global-user-minor-mode is like | |
217 | ;; vip-insert-local-user-minor-mode, except that its bindings are seen in | |
218 | ;; all Viper buffers. As with vip-vi-local-user-minor-mode, its bindings | |
219 | ;; should be done via the function vip-add-local-keys. Bindings for | |
220 | ;; vip-insert-global-user-minor-mode can be set with the define-key command. | |
221 | ;; | |
222 | ;; The next minor mode, vip-insert-kbd-minor-mode, | |
223 | ;; is used for keyboard VI-style macros defined with :map!. | |
224 | ;; | |
225 | ;; The fifth minor mode, vip-insert-state-modifier-minor-mode, is like | |
226 | ;; vip-vi-state-modifier-minor-mode, except that it is used in the Insert | |
227 | ;; state; it can be used to modify keys in a mode-specific fashion. | |
228 | ;; | |
229 | ;; The minor mode vip-insert-diehard-minor-mode is in effect when | |
230 | ;; the user wants a high degree of Vi compatibility (a bad idea, really!). | |
231 | ;; The last minor mode, vip-insert-basic-minor-mode, is always in effect | |
232 | ;; when Viper is in insert state. It binds a small number of keys needed for | |
233 | ;; Viper's operation. | |
234 | ;; | |
235 | ;; Finally, Viper provides minor modes for overriding bindings set by Emacs | |
236 | ;; modes when Viper is in Emacs state: | |
237 | ;; | |
238 | ;; vip-emacs-local-user-minor-mode | |
239 | ;; vip-emacs-global-user-minor-mode | |
240 | ;; vip-emacs-kbd-minor-mode | |
241 | ;; vip-emacs-state-modifier-minor-mode | |
242 | ;; | |
243 | ;; These minor modes are in effect when Viper is in Emacs state. The keymap | |
244 | ;; associated with vip-emacs-global-user-minor-mode, | |
245 | ;; vip-emacs-global-user-map, overrides the global and local keymaps as | |
246 | ;; well as the minor mode keymaps set by other modes. The keymap of | |
247 | ;; vip-emacs-local-user-minor-mode, vip-emacs-local-user-map, overrides | |
248 | ;; everything, but it is used on a per buffer basis. | |
249 | ;; The keymap associated with vip-emacs-state-modifier-minor-mode | |
250 | ;; overrides keys on a per-major-mode basis. The mode | |
251 | ;; vip-emacs-kbd-minor-mode is used to define Vi-style macros in Emacs | |
252 | ;; state. | |
253 | ;; | |
254 | ;; 3. There is also one minor mode that is used when Viper is in its | |
255 | ;; replace-state (used for commands like cw, C, etc.). This mode is | |
256 | ;; called | |
257 | ;; | |
258 | ;; vip-replace-minor-mode | |
259 | ;; | |
260 | ;; and its keymap is vip-replace-map. Replace minor mode is always | |
261 | ;; used in conjunction with the minor modes for insert-state, and its | |
262 | ;; keymap overshadows the keymaps for insert minor modes. | |
263 | ;; | |
264 | ;; 4. Defining buffer-local bindings in Vi and Insert modes. | |
265 | ;; As mentioned before, sometimes, it is convenient to have | |
266 | ;; buffer-specific of mode-specific key bindings in Vi and insert modes. | |
267 | ;; Viper provides a special function, vip-add-local-keys, to do precisely | |
268 | ;; this. For instance, is you need to add couple of mode-specific bindings | |
269 | ;; to Insert mode, you can put | |
270 | ;; | |
271 | ;; (vip-add-local-keys 'insert-state '((key1 . func1) (key2 .func2))) | |
272 | ;; | |
273 | ;; somewhere in a hook of this major mode. If you put something like this | |
274 | ;; in your own elisp function, this will define bindings specific to the | |
275 | ;; buffer that was current at the time of the call to vip-add-local-keys. | |
276 | ;; The only thing to make sure here is that the major mode of this buffer | |
277 | ;; is written according to Emacs conventions, which includes a call to | |
278 | ;; (kill-all-local-variables). See vip-add-local-keys for more details. | |
279 | ;; | |
280 | ;; | |
281 | ;; TO DO (volunteers?): | |
282 | ;; | |
283 | ;; 1. Some of the code that is inherited from VIP-3.5 is rather | |
284 | ;; convoluted. Instead of vip-command-argument, keymaps should bind the | |
285 | ;; actual commands. E.g., "dw" should be bound to a generic command | |
286 | ;; vip-delete that will delete things based on the value of | |
287 | ;; last-command-char. This would greatly simplify the logic and the code. | |
288 | ;; | |
289 | ;; 2. Somebody should venture to write a customization package a la | |
290 | ;; options.el that would allow the user to change values of variables | |
291 | ;; that meet certain specs (e.g., match a regexp) and whose doc string | |
292 | ;; starts with a '*'. Then, the user should be offered to save | |
293 | ;; variables that were changed. This will make user's customization job | |
294 | ;; much easier. | |

370 | "Viper Is a Package for Emacs Rebels. | |
371 | It is also a VI Plan for Emacs Rescue and a venomous VI PERil. | |
372 | ||
373 | Technically speaking, Viper is a Vi emulation package for GNU Emacs 19 and | |
374 | XEmacs 19. It supports virtually all of Vi and Ex functionality, extending | |
375 | and improving upon much of it. | |
376 | ||
377 | 1. Viper supports Vi at several levels. Level 1 is the closest to Vi, | |
378 | level 5 provides the most flexibility to depart from many Vi conventions. | |
379 | ||
380 | You will be asked to specify your user level in a following screen. | |
381 | ||
382 | If you select user level 1 then the keys ^X, ^C, ^Z, and ^G will behave | |
383 | as in VI, to smooth transition to Viper for the beginners. However, to | |
384 | use Emacs productively, you are advised to reach user level 3 or higher. | |
385 | ||
386 | If your user level is 2 or higher, ^X and ^C will invoke Emacs | |
387 | functions,as usual in Emacs; ^Z will toggle vi/emacs modes, and | |
388 | ^G will be the usual Emacs's keyboard-quit (something like ^C in VI). | |
389 | ||
390 | 2. Vi exit functions (e.g., :wq, ZZ) work on INDIVIDUAL files -- they | |
391 | do not cause Emacs to quit, except at user level 1 (a novice). | |
392 | 3. ^X^C EXITS EMACS. | |
393 | 4. Viper supports multiple undo: `u' will undo. Typing `.' will repeat | |
394 | undo. Another `u' changes direction. | |
395 | ||
