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

107 | ;; | |
108 | ;;; Notes: | |
109 | ;; | |
110 | ;; 1. Major modes. | |
111 | ;; In most cases, Viper handles major modes correctly, i.e., they come up | |
112 | ;; in the right state (either vi-state or emacs-state). For instance, text | |
113 | ;; files come up in vi-state, while, say, Dired appears in emacs-state by | |
114 | ;; default. | |
115 | ;; However, some modes do not appear in the right mode in the beginning, | |
116 | ;; usually because they neglect to follow Emacs conventions (e.g., they don't | |
27a0a490 | 117 | ;; use (kill-all-local-variables) when they start). Some major modes |
6c2e12f4 KH |
118 | ;; may fail to come up in emacs-state if they call hooks, such as |
119 | ;; text-hook, for no good reason. | |
120 | ;; | |
121 | ;; As an immediate solution, you can hit C-z to bring about the right mode. | |
122 | ;; An interim solution is to add an appropriate hook to the mode like this: | |
123 | ;; | |
124 | ;; (add-hook 'your-favorite-mode 'viper-mode) | |
125 | ;; or | |
126 | ;; (add-hook 'your-favorite-mode 'vip-change-state-to-emacs) | |
127 | ;; | |
128 | ;; whichever applies. The right thing to do, however, is to complain to the | |
129 | ;; author of the respective package. (Sometimes they also neglect to equip | |
130 | ;; their modes with hooks, which is one more reason for complaining.) | |
131 | ;; | |
132 | ;; 2. Keymap handling | |
133 | ;; Because Emacs 19 has an elegant mechanism for turning minor mode keymaps | |
134 | ;; on and off, implementation of Viper has been greatly simplified. Viper | |
135 | ;; has several minor modes. | |
136 | ;; | |
137 | ;; Viper's Vi state consists of seven minor modes: | |
138 | ;; | |
139 | ;; vip-vi-intercept-minor-mode | |
140 | ;; vip-vi-local-user-minor-mode | |
141 | ;; vip-vi-global-user-minor-mode | |
142 | ;; vip-vi-kbd-minor-mode | |
143 | ;; vip-vi-state-modifier-minor-mode | |
144 | ;; vip-vi-diehard-minor-mode | |
145 | ;; vip-vi-basic-minor-mode | |
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 | ;; | |
150 | ;; The last vip-vi-basic-minor-mode contains most of the usual Vi bindings | |
151 | ;; in its edit mode. This mode provides access to all Emacs facilities. | |
152 | ;; Novice users, however, may want to set their vip-expert-level to 1 | |
153 | ;; in their .vip file. This will enable vip-vi-diehard-minor-mode. This | |
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 | ;; | |
158 | ;; An skilled user, should set vip-expert-level to at least 3. This will | |
159 | ;; enable ;; C-c and many Emacs facilities will become available. | |
160 | ;; In this case, vip-vi-diehard-minor-mode is inactive. | |
161 | ;; | |
162 | ;; Viper gurus should have at least | |
163 | ;; (setq vip-expert-level 4) | |
164 | ;; in their ~/.vip files. This will unsuppress all Emacs keys that are not | |
165 | ;; essential for VI-style editing. | |
166 | ;; Pick-and-choose users may want to put | |
167 | ;; (setq vip-expert-level 5) | |
168 | ;; in ~/.vip. Viper will then leave it up to the user to set the variables | |
169 | ;; vip-want-* See vip-set-expert-level for details. | |
170 | ;; | |
171 | ;; The very first minor mode, vip-vi-intercept-minor-mode, is of no | |
172 | ;; concern for the user. It is needed to bind Viper's vital keys, such as | |
173 | ;; ESC and C-z. | |
174 | ;; | |
175 | ;; The second mode, vip-vi-local-user-minor-mode, usually has an | |
176 | ;; empty keymap. However, the user can set bindings in this keymap, which | |
177 | ;; will overshadow the corresponding bindings in the other two minor | |
178 | ;; modes. This is useful, for example, for setting up ZZ in gnus, | |
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. | |
182 | ;; Setting local keys is tricky, so don't do it directly. Instead, use | |
183 | ;; vip-add-local-keys function (see its doc). | |
184 | ;; | |
185 | ;; The third minor mode, vip-vi-global-user-minor-mode, is also intended | |
186 | ;; for the users but, unlike vip-vi-local-user-minor-mode, its key | |
187 | ;; bindings are seen in all Viper buffers. This mode keys can be done | |
188 | ;; with define-key command. | |
189 | ;; | |
190 | ;; The fourth minor mode, vip-vi-kbd-minor-mode, is used by keyboard | |
191 | ;; macros. Users are NOT supposed to modify this keymap directly. | |
192 | ;; | |
193 | ;; The fifth mode, vip-vi-state-modifier-minor-mode, can be used to set | |
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 | |
197 | ;; vip-vi-local-user-minor-mode, vip-vi-global-user-minor-mode, | |
198 | ;; and vip-vi-state-modifier-minor-mode only. | |
199 | ;; | |
200 | ;; Viper's Insert state also has seven minor modes: | |
201 | ;; | |
202 | ;; vip-insert-intercept-minor-mode | |
203 | ;; vip-insert-local-user-minor-mode | |
204 | ;; vip-insert-global-user-minor-mode | |
205 | ;; vip-insert-kbd-minor-mode | |
206 | ;; vip-insert-state-modifier-minor-mode | |
207 | ;; vip-insert-diehard-minor-mode | |
208 | ;; vip-insert-basic-minor-mode | |
209 | ;; | |
210 | ;; As with VI's editing modes, the first mode, vip-insert-intercept-minor-mode | |
211 | ;; is used to bind vital keys that are not to be changed by the user. | |
212 | ;; | |
213 | ;; The next mode, vip-insert-local-user-minor-mode, is used to customize | |
214 | ;; bindings in the insert state of Viper. The third mode, | |
215 | ;; vip-insert-global-user-minor-mode is like | |
216 | ;; vip-insert-local-user-minor-mode, except that its bindings are seen in | |
217 | ;; all Viper buffers. As with vip-vi-local-user-minor-mode, its bindings | |
218 | ;; should be done via the function vip-add-local-keys. Bindings for | |
219 | ;; vip-insert-global-user-minor-mode can be set with the define-key command. | |
220 | ;; | |
221 | ;; The next minor mode, vip-insert-kbd-minor-mode, | |
222 | ;; is used for keyboard VI-style macros defined with :map!. | |
223 | ;; | |
224 | ;; The fifth minor mode, vip-insert-state-modifier-minor-mode, is like | |
225 | ;; vip-vi-state-modifier-minor-mode, except that it is used in the Insert | |
226 | ;; state; it can be used to modify keys in a mode-specific fashion. | |
227 | ;; | |
228 | ;; The minor mode vip-insert-diehard-minor-mode is in effect when | |
229 | ;; the user wants a high degree of Vi compatibility (a bad idea, really!). | |
230 | ;; The last minor mode, vip-insert-basic-minor-mode, is always in effect | |
231 | ;; when Viper is in insert state. It binds a small number of keys needed for | |
232 | ;; Viper's operation. | |
233 | ;; | |
234 | ;; Finally, Viper provides minor modes for overriding bindings set by Emacs | |
235 | ;; modes when Viper is in Emacs state: | |
236 | ;; | |
237 | ;; vip-emacs-local-user-minor-mode | |
238 | ;; vip-emacs-global-user-minor-mode | |
239 | ;; vip-emacs-kbd-minor-mode | |
240 | ;; vip-emacs-state-modifier-minor-mode | |
241 | ;; | |
242 | ;; These minor modes are in effect when Viper is in Emacs state. The keymap | |
243 | ;; associated with vip-emacs-global-user-minor-mode, | |
244 | ;; vip-emacs-global-user-map, overrides the global and local keymaps as | |
245 | ;; well as the minor mode keymaps set by other modes. The keymap of | |
246 | ;; vip-emacs-local-user-minor-mode, vip-emacs-local-user-map, overrides | |
247 | ;; everything, but it is used on a per buffer basis. | |
248 | ;; The keymap associated with vip-emacs-state-modifier-minor-mode | |
249 | ;; overrides keys on a per-major-mode basis. The mode | |
250 | ;; vip-emacs-kbd-minor-mode is used to define Vi-style macros in Emacs | |
251 | ;; state. | |
252 | ;; | |
253 | ;; 3. There is also one minor mode that is used when Viper is in its | |
254 | ;; replace-state (used for commands like cw, C, etc.). This mode is | |
255 | ;; called | |
256 | ;; | |
257 | ;; vip-replace-minor-mode | |
258 | ;; | |
259 | ;; and its keymap is vip-replace-map. Replace minor mode is always | |
260 | ;; used in conjunction with the minor modes for insert-state, and its | |
261 | ;; keymap overshadows the keymaps for insert minor modes. | |
262 | ;; | |
263 | ;; 4. Defining buffer-local bindings in Vi and Insert modes. | |
264 | ;; As mentioned before, sometimes, it is convenient to have | |
265 | ;; buffer-specific of mode-specific key bindings in Vi and insert modes. | |
266 | ;; Viper provides a special function, vip-add-local-keys, to do precisely | |
267 | ;; this. For instance, is you need to add couple of mode-specific bindings | |
268 | ;; to Insert mode, you can put | |
269 | ;; | |
270 | ;; (vip-add-local-keys 'insert-state '((key1 . func1) (key2 .func2))) | |
271 | ;; | |
272 | ;; somewhere in a hook of this major mode. If you put something like this | |
273 | ;; in your own elisp function, this will define bindings specific to the | |
274 | ;; buffer that was current at the time of the call to vip-add-local-keys. | |
275 | ;; The only thing to make sure here is that the major mode of this buffer | |
276 | ;; is written according to Emacs conventions, which includes a call to | |
277 | ;; (kill-all-local-variables). See vip-add-local-keys for more details. | |
278 | ;; | |
279 | ;; | |
280 | ;; TO DO (volunteers?): | |
281 | ;; | |
282 | ;; 1. Some of the code that is inherited from VIP-3.5 is rather | |
283 | ;; convoluted. Instead of vip-command-argument, keymaps should bind the | |
284 | ;; actual commands. E.g., "dw" should be bound to a generic command | |
285 | ;; vip-delete that will delete things based on the value of | |
286 | ;; last-command-char. This would greatly simplify the logic and the code. | |
287 | ;; | |
288 | ;; 2. Somebody should venture to write a customization package a la | |
289 | ;; options.el that would allow the user to change values of variables | |
290 | ;; that meet certain specs (e.g., match a regexp) and whose doc string | |
291 | ;; starts with a '*'. Then, the user should be offered to save | |
292 | ;; variables that were changed. This will make user's customization job | |
293 | ;; much easier. | |

1130 | "Viper Is a Package for Emacs Rebels. | |
1131 | It is also a VI Plan for Emacs Rescue and a venomous VI PERil. | |
1132 | ||
4af0c23b | 1133 | Technically speaking, Viper is a Vi emulation package for GNU Emacs 19 and |
6c2e12f4 KH |
1134 | XEmacs 19. It supports virtually all of Vi and Ex functionality, extending |
1135 | and improving upon much of it. | |
1136 | ||
1137 | 1. Viper supports Vi at several levels. Level 1 is the closest to | |
1138 | Vi, level 5 provides the most flexibility to depart from many Vi | |
1139 | conventions. | |
1140 | ||
1141 | You will be asked to specify your user level in a following screen. | |
1142 | ||
1143 | If you select user level 1 then the keys ^X, ^C, ^Z, and ^G will | |
1144 | behave as in VI, to smooth transition to Viper for the beginners. | |
1145 | However, to use Emacs productively, you are advised to reach user | |
1146 | level 3 or higher. | |
1147 | ||
1148 | If your user level is 2 or higher, ^X and ^C will invoke Emacs | |
1149 | functions,as usual in Emacs; ^Z will toggle vi/emacs modes, and | |
1150 | ^G will be the usual Emacs's keyboard-quit (something like ^C in VI). | |
1151 | ||
1152 | 2. Vi exit functions (e.g., :wq, ZZ) work on INDIVIDUAL files -- they | |
1153 | do not cause Emacs to quit, except at user level 1 (a novice). | |
1154 | 3. ^X^C EXITS EMACS. | |
1155 | 4. Viper supports multiple undo: `u' will undo. Typing `.' will repeat | |
1156 | undo. Another `u' changes direction. | |
1157 | ||
1158 | 6. Emacs Meta functions are invoked by typing `_' or `\\ ESC'. | |
1159 | On a window system, the best way is to use the Meta-key. | |
1160 | 7. Try \\[keyboard-quit] and \\[abort-recursive-edit] repeatedly, | |
1161 | if something funny happens. This would abort the current editing | |
1162 | command. | |
1163 | ||
1164 | You can get more information on Viper by: | |
1165 | ||
1166 | a. Typing `:help' in Vi state | |
1167 | b. Printing Viper manual, found in ./etc/viper.dvi | |
1168 | c. Printing ViperCard, the Quick Reference, found in ./etc/viperCard.dvi | |

2817 | ;; dabbrev-expand. The problem stems from new-dabbrev.el, which | |
2818 | ;; sometimes simply shifts the repl region rightwards, without | |
2819 | ;; deleting an equal amount of characters. | |
2820 | ;; | |
2821 | ;; The reason why new-dabbrev.el causes this are this: | |
2822 | ;; if one dinamically completes a partial word that starts before the | |
2823 | ;; replacement region (but ends inside)then new-dabbrev.el first | |
2824 | ;; moves cursor backwards, to the beginning of the word to be | |
2825 | ;; completed (say, pt A). Then it inserts the | |
2826 | ;; completed word and then deletes the old, incomplete part. | |
2827 | ;; Since the complete word is inserted at position before the repl | |
2828 | ;; region, the next If-statement would have set chars-to-delete to 0 | |
2829 | ;; unless we check for the current command, which must be | |
2830 | ;; dabbrev-expand. | |
2831 | ;; | |
2832 | ;; We should be able deal with these problems in a better way | |
2833 | ;; when emacs will have overlays with sticky back ends. | |
2834 | ;; In fact, it would be also useful to add overlays for insert | |
2835 | ;; regions as well, since this will let us capture the situation when | |
2836 | ;; dabbrev-expand goes back past the insertion point to find the | |
2837 | ;; beginning of the word to be expanded. | |

4949 | This is VIPER | |

4951 | @joke | |
4952 | Viper Is a Package for Emacs Rebels, | |
4953 | a VI Plan for Emacs Rescue, | |
4954 | and a venomous VI PERil. | |
4955 | @end joke | |
4956 | ||
4957 | Technically speaking, Viper is a new Vi emulator that replaces | |
4958 | the old VIP package. | |
4959 | ||
4960 | Viper emulates Vi much better than VIP. It also significantly | |
4961 | extends and improves upon Vi in many useful ways. | |
4962 | ||
4963 | Although many VIP settings in your ~/.vip are compatible with Viper, | |
4964 | you may have to change some of them. Please refer to the documentation, | |
4965 | which can be obtained by executing | |
4966 | ||
4967 | :help | |
4968 | ||
4969 | when Viper is in Vi state. | |
4970 | ||
4971 | If you will be so lucky as to find a bug, report it via the command | |
4972 | ||
4973 | :submitReport | |

5172 | PLEASE FOLLOW THESE PROCEDURES | |
5173 | ------------------------------ | |
5174 | ||
5175 | Before reporting a bug, please verify that it is related to Viper, and is | |
5176 | not cause by other packages you are using. | |
5177 | ||
5178 | Don't report compilation warnings, unless you are certain that there is a | |
5179 | problem. These warnings are normal and unavoidable. | |
5180 | ||
5181 | Please note that users should not modify variables and keymaps other than | |
5182 | those advertised in the manual. Such `customization' is likely to crash | |
5183 | Viper, as it would any other improperly customized Emacs package. | |
5184 | ||
5185 | If you are reporting an error message received while executing one of the | |
5186 | Viper commands, type: | |
5187 | ||
5188 | M-x set-variable <Return> debug-on-error <Return> t <Return> | |
5189 | ||
5190 | Then reproduce the error. The above command will cause Emacs to produce a | |
5191 | back trace of the execution that leads to the error. Please include this | |
5192 | trace in your bug report. | |
5193 | ||
5194 | If you believe that one of Viper's commands goes into an infinite loop | |
5195 | \(e.g., Emacs freezes\), type: | |
5196 | ||
5197 | M-x set-variable <Return> debug-on-quit <Return> t <Return> | |
5198 | ||
5199 | Then reproduce the problem. Wait for a few seconds, then type C-g to abort | |
5200 | the current command. Include the resulting back trace in the bug report. | |
