38 ;; Viper is a full-featured Vi emulator for Emacs and XEmacs. It emulates and
39 ;; improves upon the standard features of Vi and, at the same time, allows
40 ;; full access to all Emacs facilities. Viper supports multiple undo,
41 ;; file name completion, command, file, and search history and it extends
42 ;; Vi in many other ways. Viper is highly customizable through the various
43 ;; hooks, user variables, and keymaps. It is implemented as a collection
44 ;; of minor modes and it is designed to provide full access to all Emacs
45 ;; major and minor modes.
49 ;; Viper is a new name for a package formerly known as VIP-19,
50 ;; which was a successor of VIP version 3.5 by Masahiko Sato
51 ;; <ms@sail.stanford.edu> and VIP version 4.2 by Aamod Sane
52 ;; <sane@cs.uiuc.edu>. Some ideas from vip 4.4.2 by Aamod Sane
53 ;; were also shamelessly plagiarized.
55 ;; Viper maintains some degree of compatibility with these older
56 ;; packages. See the documentation for customization.
58 ;; The main difference between Viper and these older packages are:
60 ;; 1. Viper emulates Vi at several levels, from almost complete conformity
61 ;; to a rather loose Vi-compliance.
63 ;; 2. Viper provides full access to all major and minor modes of Emacs
64 ;; without the need to type extra keys.
65 ;; The older versions of VIP (and other Vi emulators) do not work with
66 ;; some major and minor modes.
68 ;; 3. Viper supports vi-style undo.
70 ;; 4. Viper fully emulates (and improves upon) vi's replacement mode.
72 ;; 5. Viper has a better interface to ex, including command, variable, and
73 ;; file name completion.
75 ;; 6. Viper uses native Emacs history and completion features; it doesn't
76 ;; rely on other packages (such as gmhist.el and completer.el) to provide
79 ;; 7. Viper supports Vi-style editing in the minibuffer, by allowing the
80 ;; user to switch from Insert state to Vi state to Replace state, etc.
82 ;; 8. Viper keeps history of recently inserted pieces of text and recently
83 ;; executed Vi-style destructive commands, such as `i', `d', etc.
84 ;; These pieces of text can be inserted in later insertion commands;
85 ;; the previous destructive commands can be re-executed.
87 ;; 9. Viper has Vi-style keyboard macros, which enhances the similar
88 ;; facility in the original Vi.
89 ;; First, one can execute any Emacs command while defining a
90 ;; macro, not just the Vi commands. Second, macros are defined in a
91 ;; WYSYWYG mode, using an interface to Emacs' WYSIWYG style of defining
92 ;; macros. Third, in Viper, one can define macros that are specific to
93 ;; a given buffer, a given major mode, or macros defined for all buffers.
94 ;; The same macro name can have several different definitions:
95 ;; one global, several definitions for various major modes, and
96 ;; definitions for specific buffers.
97 ;; Buffer-specific definitions override mode-specific
98 ;; definitions, which, in turn, override global definitions.
107 ;;; Acknowledgements:
109 ;; Bug reports and ideas contributed by many users have helped
110 ;; improve Viper and the various versions of VIP.
111 ;; See the on-line manual for a complete list of contributors.
117 ;; In most cases, Viper handles major modes correctly, i.e., they come up
118 ;; in the right state (either vi-state or emacs-state). For instance, text
119 ;; files come up in vi-state, while, say, Dired appears in emacs-state by
121 ;; However, some modes do not appear in the right mode in the beginning,
122 ;; usually because they neglect to follow Emacs conventions (e.g., they don't
123 ;; use kill-all-local-variables when they start). Some major modes
124 ;; may fail to come up in emacs-state if they call hooks, such as
125 ;; text-hook, for no good reason.
127 ;; As an immediate solution, you can hit C-z to bring about the right mode.
128 ;; An interim solution is to add an appropriate hook to the mode like this:
130 ;; (add-hook 'your-favorite-mode 'viper-mode)
132 ;; (add-hook 'your-favorite-mode 'viper-change-state-to-emacs)
134 ;; whichever applies. The right thing to do, however, is to complain to the
135 ;; author of the respective package. (Sometimes they also neglect to equip
136 ;; their modes with hooks, which is one more reason for complaining.)
138 ;; 2. Keymap handling
139 ;; Each Viper state (insert, vi, replace) is implemented as a collection of
140 ;; several minor modes, each with its own keymap.
142 ;; Viper's Vi state consists of seven minor modes:
144 ;; viper-vi-intercept-minor-mode
145 ;; viper-vi-local-user-minor-mode
146 ;; viper-vi-global-user-minor-mode
147 ;; viper-vi-kbd-minor-mode
148 ;; viper-vi-state-modifier-minor-mode
149 ;; viper-vi-diehard-minor-mode
150 ;; viper-vi-basic-minor-mode
152 ;; Bindings done to the keymap of the first mode overshadow those done to
153 ;; the second, which, in turn, overshadows those done to the third, etc.
155 ;; The last viper-vi-basic-minor-mode contains most of the usual Vi bindings
156 ;; in its edit mode. This mode provides access to all Emacs facilities.
157 ;; Novice users, however, may want to set their viper-expert-level to 1
158 ;; in their .viper file. This will enable viper-vi-diehard-minor-mode. This
159 ;; minor mode's bindings make Viper simulate the usual Vi very closely.
160 ;; For instance, C-c will not have its standard Emacs binding
161 ;; and so many of the goodies of Emacs are not available.
163 ;; A skilled user should set viper-expert-level to at least 3. This will
164 ;; enable `C-c' and many Emacs facilities will become available.
165 ;; In this case, viper-vi-diehard-minor-mode is inactive.
167 ;; Viper gurus should have at least
168 ;; (setq viper-expert-level 4)
169 ;; in their ~/.viper files. This will unsuppress all Emacs keys that are not
170 ;; essential for VI-style editing.
171 ;; Pick-and-choose users may want to put
172 ;; (setq viper-expert-level 5)
173 ;; in ~/.viper. Viper will then leave it up to the user to set the variables
174 ;; viper-want-* See viper-set-expert-level for details.
176 ;; The very first minor mode, viper-vi-intercept-minor-mode, is of no
177 ;; concern for the user. It is needed to bind Viper's vital keys, such as
180 ;; The second mode, viper-vi-local-user-minor-mode, usually has an
181 ;; empty keymap. However, the user can set bindings in this keymap, which
182 ;; will overshadow the corresponding bindings in the other two minor
183 ;; modes. This is useful, for example, for setting up ZZ in gnus,
184 ;; rmail, mh-e, etc., to send message instead of saving it in a file.
185 ;; Likewise, in Dired mode, you may want to bind ZN and ZP to commands
186 ;; that would visit the next or the previous file in the Dired buffer.
187 ;; Setting local keys is tricky, so don't do it directly. Instead, use
188 ;; viper-add-local-keys function (see its doc).
190 ;; The third minor mode, viper-vi-global-user-minor-mode, is also intended
191 ;; for the users but, unlike viper-vi-local-user-minor-mode, its key
192 ;; bindings are seen in all Viper buffers. This mode keys can be done
193 ;; with define-key command.
195 ;; The fourth minor mode, viper-vi-kbd-minor-mode, is used by keyboard
196 ;; macros. Users are NOT supposed to modify this keymap directly.
198 ;; The fifth mode, viper-vi-state-modifier-minor-mode, can be used to set
199 ;; key bindings that are visible in some major modes but not in others.
201 ;; Users are allowed to modify keymaps that belong to
202 ;; viper-vi-local-user-minor-mode, viper-vi-global-user-minor-mode,
203 ;; and viper-vi-state-modifier-minor-mode only.
205 ;; Viper's Insert state also has seven minor modes:
207 ;; viper-insert-intercept-minor-mode
208 ;; viper-insert-local-user-minor-mode
209 ;; viper-insert-global-user-minor-mode
210 ;; viper-insert-kbd-minor-mode
211 ;; viper-insert-state-modifier-minor-mode
212 ;; viper-insert-diehard-minor-mode
213 ;; viper-insert-basic-minor-mode
215 ;; As with VI's editing modes, the first mode,
216 ;; viper-insert-intercept-minor-mode is used to bind vital keys that are not
217 ;; to be changed by the user.
219 ;; The next mode, viper-insert-local-user-minor-mode, is used to customize
220 ;; bindings in the insert state of Viper. The third mode,
221 ;; viper-insert-global-user-minor-mode is like
222 ;; viper-insert-local-user-minor-mode, except that its bindings are seen in
223 ;; all Viper buffers. As with viper-vi-local-user-minor-mode, its bindings
224 ;; should be done via the function viper-add-local-keys. Bindings for
225 ;; viper-insert-global-user-minor-mode can be set with the define-key command.
227 ;; The next minor mode, viper-insert-kbd-minor-mode,
228 ;; is used for keyboard VI-style macros defined with :map!.
230 ;; The fifth minor mode, viper-insert-state-modifier-minor-mode, is like
231 ;; viper-vi-state-modifier-minor-mode, except that it is used in the Insert
232 ;; state; it can be used to modify keys in a mode-specific fashion.
234 ;; The minor mode viper-insert-diehard-minor-mode is in effect when
235 ;; the user wants a high degree of Vi compatibility (a bad idea, really!).
236 ;; The last minor mode, viper-insert-basic-minor-mode, is always in effect
237 ;; when Viper is in insert state. It binds a small number of keys needed for
238 ;; Viper's operation.
240 ;; Finally, Viper provides minor modes for overriding bindings set by Emacs
241 ;; modes when Viper is in Emacs state:
243 ;; viper-emacs-local-user-minor-mode
244 ;; viper-emacs-global-user-minor-mode
245 ;; viper-emacs-kbd-minor-mode
246 ;; viper-emacs-state-modifier-minor-mode
248 ;; These minor modes are in effect when Viper is in Emacs state. The keymap
249 ;; associated with viper-emacs-global-user-minor-mode,
250 ;; viper-emacs-global-user-map, overrides the global and local keymaps as
251 ;; well as the minor mode keymaps set by other modes. The keymap of
252 ;; viper-emacs-local-user-minor-mode, viper-emacs-local-user-map, overrides
253 ;; everything, but it is used on a per buffer basis.
254 ;; The keymap associated with viper-emacs-state-modifier-minor-mode
255 ;; overrides keys on a per-major-mode basis. The mode
256 ;; viper-emacs-kbd-minor-mode is used to define Vi-style macros in Emacs
259 ;; 3. There is also one minor mode that is used when Viper is in its
260 ;; replace-state (used for commands like cw, C, etc.). This mode is
263 ;; viper-replace-minor-mode
265 ;; and its keymap is viper-replace-map. Replace minor mode is always
266 ;; used in conjunction with the minor modes for insert-state, and its
267 ;; keymap overshadows the keymaps for insert minor modes.
269 ;; 4. Defining buffer-local bindings in Vi and Insert modes.
270 ;; As mentioned before, sometimes, it is convenient to have
271 ;; buffer-specific of mode-specific key bindings in Vi and insert modes.
272 ;; Viper provides a special function, viper-add-local-keys, to do precisely
273 ;; this. For instance, is you need to add couple of mode-specific bindings
274 ;; to Insert mode, you can put
276 ;; (viper-add-local-keys 'insert-state '((key1 . func1) (key2 .func2)))
278 ;; somewhere in a hook of this major mode. If you put something like this
279 ;; in your own elisp function, this will define bindings specific to the
280 ;; buffer that was current at the time of the call to viper-add-local-keys.
281 ;; The only thing to make sure here is that the major mode of this buffer
282 ;; is written according to Emacs conventions, which includes a call to
283 ;; (kill-all-local-variables). See viper-add-local-keys for more details.
286 ;; TO DO (volunteers?):
288 ;; 1. Some of the code that is inherited from VIP-3.5 is rather
289 ;; convoluted. Instead of viper-command-argument, keymaps should bind the
290 ;; actual commands. E.g., "dw" should be bound to a generic command
291 ;; viper-delete that will delete things based on the value of
292 ;; last-command-event. This would greatly simplify the logic and the code.
294 ;; 2. Somebody should venture to write a customization package a la
295 ;; options.el that would allow the user to change values of variables
296 ;; that meet certain specs (e.g., match a regexp) and whose doc string
297 ;; starts with a '*'. Then, the user should be offered to save
298 ;; variables that were changed. This will make user's customization job

551 Incidentally, Viper emulates Vi under GNU Emacs 20 and XEmacs 20.
552 It supports all of what is good in Vi and Ex, while extending
553 and improving upon much of it.
555 1. Viper supports Vi at several levels. Level 1 is the closest to Vi,
556 level 5 provides the most flexibility to depart from many Vi conventions.
558 You will be asked to specify your user level in a following screen.
560 If you select user level 1 then the keys ^X, ^C, ^Z, and ^G will behave
561 as in VI, to smooth transition to Viper for the beginners. However, to
562 use Emacs productively, you are advised to reach user level 3 or higher.
564 At user level 2 or higher, ^X and ^C have Emacs, not Vi, bindings;
565 ^Z toggles Vi/Emacs states; ^G is Emacs' keyboard-quit (like ^C in Vi).
567 2. Vi exit functions (e.g., :wq, ZZ) work on INDIVIDUAL files -- they
568 do not cause Emacs to quit, except at user level 1 (for a novice).
570 4. Viper supports multiple undo: `u' will undo. Typing `.' will repeat
571 undo. Another `u' changes direction.
573 6. Emacs Meta key is `C-\\' (in all modes) or `\\ ESC' (in Vi command mode).
574 On a window system, the best way is to use the Meta-key on your keyboard.
575 7. Try \\[keyboard-quit] and \\[abort-recursive-edit] repeatedly,if
576 something funny happens. This would abort the current editing command.

580 a. Type `:help' in Vi command mode
581 b. Print Viper manual, found in ./etc/viper.dvi
582 c. Print the Quick Reference, found in ./etc/viperCard.dvi
584 To submit a bug report or to contact the author, type :submitReport in Vi
