3af0304a | 33 | ;; Viper is a full-featured Vi emulator for Emacs and XEmacs. It emulates and |
6c2e12f4 KH |
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 | |
3af0304a | 37 | ;; Vi in many other ways. Viper is highly customizable through the various |
6c2e12f4 KH |
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 | |
3af0304a | 47 | ;; <sane@cs.uiuc.edu>. Some ideas from vip 4.4.2 by Aamod Sane |
6c2e12f4 KH |
48 | ;; were also shamelessly plagiarized. |
49 | ;; | |
50 | ;; Viper maintains some degree of compatibility with these older | |
3af0304a | 51 | ;; packages. See the documentation for customization. |
6c2e12f4 KH |
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 | |
3af0304a | 85 | ;; macro, not just the Vi commands. Second, macros are defined in a |
6c2e12f4 | 86 | ;; WYSYWYG mode, using an interface to Emacs' WYSIWYG style of defining |
3af0304a | 87 | ;; macros. Third, in Viper, one can define macros that are specific to |
6c2e12f4 KH |
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 | |
3af0304a | 113 | ;; in the right state (either vi-state or emacs-state). For instance, text |
6c2e12f4 KH |
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 | |
3af0304a | 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 | |
8626cfa2 | 127 | ;; (add-hook 'your-favorite-mode 'viper-change-state-to-emacs) |
6c2e12f4 | 128 | ;; |
3af0304a | 129 | ;; whichever applies. The right thing to do, however, is to complain to the |
6c2e12f4 KH |
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 | |
8626cfa2 MK |
134 | ;; Each Viper state (insert, vi, replace) is implemented as a collection of |
135 | ;; several minor modes, each with its own keymap. | |
6c2e12f4 KH |
136 | ;; |
137 | ;; Viper's Vi state consists of seven minor modes: | |
138 | ;; | |
8626cfa2 MK |
139 | ;; viper-vi-intercept-minor-mode |
140 | ;; viper-vi-local-user-minor-mode | |
141 | ;; viper-vi-global-user-minor-mode | |
142 | ;; viper-vi-kbd-minor-mode | |
143 | ;; viper-vi-state-modifier-minor-mode | |
144 | ;; viper-vi-diehard-minor-mode | |
145 | ;; viper-vi-basic-minor-mode | |
6c2e12f4 KH |
146 | ;; |
147 | ;; Bindings done to the keymap of the first mode overshadow those done to | |
148 | ;; the second, which, in turn, overshadows those done to the third, etc. | |
149 | ;; | |
8626cfa2 | 150 | ;; The last viper-vi-basic-minor-mode contains most of the usual Vi bindings |
3af0304a | 151 | ;; in its edit mode. This mode provides access to all Emacs facilities. |
1e70790f | 152 | ;; Novice users, however, may want to set their viper-expert-level to 1 |
3af0304a | 153 | ;; in their .viper file. This will enable viper-vi-diehard-minor-mode. This |
6c2e12f4 KH |
154 | ;; minor mode's bindings make Viper simulate the usual Vi very closely. |
155 | ;; For instance, C-c will not have its standard Emacs binding | |
156 | ;; and so many of the goodies of Emacs are not available. | |
157 | ;; | |
3af0304a | 158 | ;; A skilled user should set viper-expert-level to at least 3. This will |
d63a37ea | 159 | ;; enable `C-c' and many Emacs facilities will become available. |
8626cfa2 | 160 | ;; In this case, viper-vi-diehard-minor-mode is inactive. |
6c2e12f4 KH |
161 | ;; |
162 | ;; Viper gurus should have at least | |
1e70790f | 163 | ;; (setq viper-expert-level 4) |
3af0304a | 164 | ;; in their ~/.viper files. This will unsuppress all Emacs keys that are not |
6c2e12f4 KH |
165 | ;; essential for VI-style editing. |
166 | ;; Pick-and-choose users may want to put | |
1e70790f | 167 | ;; (setq viper-expert-level 5) |
3af0304a | 168 | ;; in ~/.viper. Viper will then leave it up to the user to set the variables |
8626cfa2 | 169 | ;; viper-want-* See viper-set-expert-level for details. |
6c2e12f4 | 170 | ;; |
8626cfa2 | 171 | ;; The very first minor mode, viper-vi-intercept-minor-mode, is of no |
3af0304a | 172 | ;; concern for the user. It is needed to bind Viper's vital keys, such as |
6c2e12f4 KH |
173 | ;; ESC and C-z. |
174 | ;; | |
8626cfa2 | 175 | ;; The second mode, viper-vi-local-user-minor-mode, usually has an |
3af0304a | 176 | ;; empty keymap. However, the user can set bindings in this keymap, which |
6c2e12f4 | 177 | ;; will overshadow the corresponding bindings in the other two minor |
3af0304a | 178 | ;; modes. This is useful, for example, for setting up ZZ in gnus, |
6c2e12f4 KH |
179 | ;; rmail, mh-e, etc., to send message instead of saving it in a file. |
180 | ;; Likewise, in Dired mode, you may want to bind ZN and ZP to commands | |
181 | ;; that would visit the next or the previous file in the Dired buffer. | |
3af0304a | 182 | ;; Setting local keys is tricky, so don't do it directly. Instead, use |
8626cfa2 | 183 | ;; viper-add-local-keys function (see its doc). |
6c2e12f4 | 184 | ;; |
8626cfa2 MK |
185 | ;; The third minor mode, viper-vi-global-user-minor-mode, is also intended |
186 | ;; for the users but, unlike viper-vi-local-user-minor-mode, its key | |
3af0304a | 187 | ;; bindings are seen in all Viper buffers. This mode keys can be done |
6c2e12f4 KH |
188 | ;; with define-key command. |
189 | ;; | |
8626cfa2 | 190 | ;; The fourth minor mode, viper-vi-kbd-minor-mode, is used by keyboard |
3af0304a | 191 | ;; macros. Users are NOT supposed to modify this keymap directly. |
6c2e12f4 | 192 | ;; |
8626cfa2 | 193 | ;; The fifth mode, viper-vi-state-modifier-minor-mode, can be used to set |
6c2e12f4 KH |
194 | ;; key bindings that are visible in some major modes but not in others. |
195 | ;; | |
196 | ;; Users are allowed to modify keymaps that belong to | |
8626cfa2 MK |
197 | ;; viper-vi-local-user-minor-mode, viper-vi-global-user-minor-mode, |
198 | ;; and viper-vi-state-modifier-minor-mode only. | |
6c2e12f4 KH |
199 | ;; |
200 | ;; Viper's Insert state also has seven minor modes: | |
201 | ;; | |
8626cfa2 MK |
202 | ;; viper-insert-intercept-minor-mode |
203 | ;; viper-insert-local-user-minor-mode | |
204 | ;; viper-insert-global-user-minor-mode | |
205 | ;; viper-insert-kbd-minor-mode | |
206 | ;; viper-insert-state-modifier-minor-mode | |
207 | ;; viper-insert-diehard-minor-mode | |
208 | ;; viper-insert-basic-minor-mode | |
6c2e12f4 | 209 | ;; |
8626cfa2 MK |
210 | ;; As with VI's editing modes, the first mode, |
211 | ;; viper-insert-intercept-minor-mode is used to bind vital keys that are not | |
212 | ;; to be changed by the user. | |
6c2e12f4 | 213 | ;; |
8626cfa2 | 214 | ;; The next mode, viper-insert-local-user-minor-mode, is used to customize |
3af0304a | 215 | ;; bindings in the insert state of Viper. The third mode, |
8626cfa2 MK |
216 | ;; viper-insert-global-user-minor-mode is like |
217 | ;; viper-insert-local-user-minor-mode, except that its bindings are seen in | |
3af0304a MK |
218 | ;; all Viper buffers. As with viper-vi-local-user-minor-mode, its bindings |
219 | ;; should be done via the function viper-add-local-keys. Bindings for | |
8626cfa2 | 220 | ;; viper-insert-global-user-minor-mode can be set with the define-key command. |
6c2e12f4 | 221 | ;; |
8626cfa2 | 222 | ;; The next minor mode, viper-insert-kbd-minor-mode, |
6c2e12f4 KH |
223 | ;; is used for keyboard VI-style macros defined with :map!. |
224 | ;; | |
8626cfa2 MK |
225 | ;; The fifth minor mode, viper-insert-state-modifier-minor-mode, is like |
226 | ;; viper-vi-state-modifier-minor-mode, except that it is used in the Insert | |
6c2e12f4 KH |
227 | ;; state; it can be used to modify keys in a mode-specific fashion. |
228 | ;; | |
8626cfa2 | 229 | ;; The minor mode viper-insert-diehard-minor-mode is in effect when |
6c2e12f4 | 230 | ;; the user wants a high degree of Vi compatibility (a bad idea, really!). |
8626cfa2 | 231 | ;; The last minor mode, viper-insert-basic-minor-mode, is always in effect |
3af0304a | 232 | ;; when Viper is in insert state. It binds a small number of keys needed for |
6c2e12f4 KH |
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 | ;; | |
8626cfa2 MK |
238 | ;; viper-emacs-local-user-minor-mode |
239 | ;; viper-emacs-global-user-minor-mode | |
240 | ;; viper-emacs-kbd-minor-mode | |
241 | ;; viper-emacs-state-modifier-minor-mode | |
6c2e12f4 | 242 | ;; |
3af0304a | 243 | ;; These minor modes are in effect when Viper is in Emacs state. The keymap |
8626cfa2 MK |
244 | ;; associated with viper-emacs-global-user-minor-mode, |
245 | ;; viper-emacs-global-user-map, overrides the global and local keymaps as | |
3af0304a | 246 | ;; well as the minor mode keymaps set by other modes. The keymap of |
8626cfa2 | 247 | ;; viper-emacs-local-user-minor-mode, viper-emacs-local-user-map, overrides |
6c2e12f4 | 248 | ;; everything, but it is used on a per buffer basis. |
8626cfa2 | 249 | ;; The keymap associated with viper-emacs-state-modifier-minor-mode |
3af0304a | 250 | ;; overrides keys on a per-major-mode basis. The mode |
8626cfa2 | 251 | ;; viper-emacs-kbd-minor-mode is used to define Vi-style macros in Emacs |
6c2e12f4 KH |
252 | ;; state. |
253 | ;; | |
254 | ;; 3. There is also one minor mode that is used when Viper is in its | |
3af0304a | 255 | ;; replace-state (used for commands like cw, C, etc.). This mode is |
6c2e12f4 KH |
256 | ;; called |
257 | ;; | |
8626cfa2 | 258 | ;; viper-replace-minor-mode |
6c2e12f4 | 259 | ;; |
3af0304a | 260 | ;; and its keymap is viper-replace-map. Replace minor mode is always |
6c2e12f4 KH |
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. | |
8626cfa2 | 267 | ;; Viper provides a special function, viper-add-local-keys, to do precisely |
3af0304a | 268 | ;; this. For instance, is you need to add couple of mode-specific bindings |
6c2e12f4 KH |
269 | ;; to Insert mode, you can put |
270 | ;; | |
8626cfa2 | 271 | ;; (viper-add-local-keys 'insert-state '((key1 . func1) (key2 .func2))) |
6c2e12f4 | 272 | ;; |
3af0304a | 273 | ;; somewhere in a hook of this major mode. If you put something like this |
6c2e12f4 | 274 | ;; in your own elisp function, this will define bindings specific to the |
8626cfa2 | 275 | ;; buffer that was current at the time of the call to viper-add-local-keys. |
6c2e12f4 KH |
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 | |
3af0304a | 278 | ;; (kill-all-local-variables). See viper-add-local-keys for more details. |
6c2e12f4 KH |
279 | ;; |
280 | ;; | |
281 | ;; TO DO (volunteers?): | |
282 | ;; | |
283 | ;; 1. Some of the code that is inherited from VIP-3.5 is rather | |
3af0304a MK |
284 | ;; convoluted. Instead of viper-command-argument, keymaps should bind the |
285 | ;; actual commands. E.g., "dw" should be bound to a generic command | |
8626cfa2 | 286 | ;; viper-delete that will delete things based on the value of |
3af0304a | 287 | ;; last-command-char. This would greatly simplify the logic and the code. |
6c2e12f4 KH |
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 | |
3af0304a MK |
292 | ;; starts with a '*'. Then, the user should be offered to save |
293 | ;; variables that were changed. This will make user's customization job | |
6c2e12f4 KH |
294 | ;; much easier. |

537 | a VI Plan for Emacs Rescue, and a venomous VI PERil. | |
e36a387d | 538 | |
1e70790f MK |
539 | Incidentally, Viper emulates Vi under GNU Emacs 20 and XEmacs 20. |
540 | It supports all of what is good in Vi and Ex, while extending | |
e36a387d MK |
541 | and improving upon much of it. |
542 | ||
3af0304a | 543 | 1. Viper supports Vi at several levels. Level 1 is the closest to Vi, |
e36a387d MK |
544 | level 5 provides the most flexibility to depart from many Vi conventions. |
545 | ||
546 | You will be asked to specify your user level in a following screen. | |
547 | ||
548 | If you select user level 1 then the keys ^X, ^C, ^Z, and ^G will behave | |
3af0304a | 549 | as in VI, to smooth transition to Viper for the beginners. However, to |
e36a387d MK |
550 | use Emacs productively, you are advised to reach user level 3 or higher. |
551 | ||
1e70790f MK |
552 | At user level 2 or higher, ^X and ^C have Emacs, not Vi, bindings; |
553 | ^Z toggles Vi/Emacs states; ^G is Emacs' keyboard-quit (like ^C in Vi). | |
e36a387d MK |
554 | |
555 | 2. Vi exit functions (e.g., :wq, ZZ) work on INDIVIDUAL files -- they | |
1e70790f | 556 | do not cause Emacs to quit, except at user level 1 (for a novice). |
e36a387d | 557 | 3. ^X^C EXITS EMACS. |
3af0304a MK |
558 | 4. Viper supports multiple undo: `u' will undo. Typing `.' will repeat |
559 | undo. Another `u' changes direction. | |
e36a387d | 560 | |
1e70790f MK |
561 | 6. Emacs Meta key is `C-\\' (in all modes) or `\\ ESC' (in Vi command mode). |
562 | On a window system, the best way is to use the Meta-key on your keyboard. | |
e36a387d | 563 | 7. Try \\[keyboard-quit] and \\[abort-recursive-edit] repeatedly,if |
3af0304a | 564 | something funny happens. This would abort the current editing command. |
e36a387d | 565 | |
1e70790f | 566 | For more information on Viper: |
726e270f | 567 | |
1e70790f MK |
568 | a. Type `:help' in Vi command mode |
