|
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.
|
|
78
|
92 ;; Buffer-specific definitions override mode-specific
|
|
0
|
93 ;; definitions, which, in turn, override global definitions.

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
|
|
|
118 ;; use kill-all-local-variables when they start). Some major modes
|
|
|
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 ;;
|
|
78
|
159 ;; A skilled user should set vip-expert-level to at least 3. This will
|
|
80
|
160 ;; enable `C-c' and many Emacs facilities will become available.
|
|
0
|
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.

724 "Viper Is a Package for Emacs Rebels.
|
|
|
725 It is also a VI Plan for Emacs Rescue and a venomous VI PERil.
|
|
|
726
|
|
|
727 Technically speaking, Viper is a Vi emulation package for GNU Emacs 19 and
|
|
|
728 XEmacs 19. It supports virtually all of Vi and Ex functionality, extending
|
|
|
729 and improving upon much of it.
|
|
|
730
|
|
|
731 1. Viper supports Vi at several levels. Level 1 is the closest to Vi,
|
|
|
732 level 5 provides the most flexibility to depart from many Vi conventions.
|
|
|
733
|
|
|
734 You will be asked to specify your user level in a following screen.
|
|
|
735
|
|
|
736 If you select user level 1 then the keys ^X, ^C, ^Z, and ^G will behave
|
|
|
737 as in VI, to smooth transition to Viper for the beginners. However, to
|
|
|
738 use Emacs productively, you are advised to reach user level 3 or higher.
|
|
|
739
|
|
|
740 If your user level is 2 or higher, ^X and ^C will invoke Emacs
|
|
|
741 functions,as usual in Emacs; ^Z will toggle vi/emacs modes, and
|
|
|
742 ^G will be the usual Emacs's keyboard-quit (something like ^C in VI).
|
|
|
743
|
|
|
744 2. Vi exit functions (e.g., :wq, ZZ) work on INDIVIDUAL files -- they
|
|
|
745 do not cause Emacs to quit, except at user level 1 (a novice).
|
|
|
746 3. ^X^C EXITS EMACS.
|
|
|
747 4. Viper supports multiple undo: `u' will undo. Typing `.' will repeat
|
|
|
748 undo. Another `u' changes direction.
|
|
|
749
|
|
78
|
750 6. Emacs Meta functions are invoked by typing `C-\\' or `\\ ESC'.
|
|
0
|
751 On a window system, the best way is to use the Meta-key.
|
|
|
752 7. Try \\[keyboard-quit] and \\[abort-recursive-edit] repeatedly,if
|
|
|
753 something funny happens. This would abort the current editing command.
|
|
|
754
|
|
|
755 You can get more information on Viper by:
|
|
|
756
|
|
|
757 a. Typing `:help' in Vi state
|
|
|
758 b. Printing Viper manual, found in ./etc/viper.dvi
|
|
|
759 c. Printing ViperCard, the Quick Reference, found in ./etc/viperCard.dvi
|
|
|
760
|

4686 Technically speaking, Viper is a new Vi emulator that replaces
|
|
|
4687 the old VIP package.
|
|
|
4688
|
|
|
4689 Viper emulates Vi much better than VIP. It also significantly
|
|
|
4690 extends and improves upon Vi in many useful ways.
|
|
|
4691
|
|
|
4692 Although many VIP settings in your ~/.vip are compatible with Viper,
|
|
|
4693 you may have to change some of them. Please refer to the documentation,
|
|
|
4694 which can be obtained by executing
|
|
|
4695
|

|
|
|
4897 Before reporting a bug, please verify that it is related to Viper, and is
|
|
|
4898 not cause by other packages you are using.
|
|
|
4899
|
|
|
4900 Don't report compilation warnings, unless you are certain that there is a
|
|
|
4901 problem. These warnings are normal and unavoidable.
|
|
|
4902
|
|
|
4903 Please note that users should not modify variables and keymaps other than
|
|
|
4904 those advertised in the manual. Such `customization' is likely to crash
|
|
|
4905 Viper, as it would any other improperly customized Emacs package.
|
|
|
4906
|
|
|
4907 If you are reporting an error message received while executing one of the
|
|
|
4908 Viper commands, type:
|
|
|
4909
|
|
|
4910 M-x set-variable <Return> debug-on-error <Return> t <Return>
|
|
|
4911
|
|
|
4912 Then reproduce the error. The above command will cause Emacs to produce a
|
|
|
4913 back trace of the execution that leads to the error. Please include this
|
|
|
4914 trace in your bug report.
|
|
|
4915
|
|
|
4916 If you believe that one of Viper's commands goes into an infinite loop
|
|
|
4917 \(e.g., Emacs freezes\), type:
|
|
|
4918
|
|
|
4919 M-x set-variable <Return> debug-on-quit <Return> t <Return>
|
|
|
4920
|
|
|
4921 Then reproduce the problem. Wait for a few seconds, then type C-g to abort
|
|
|
4922 the current command. Include the resulting back trace in the bug report.
