It emulates and +;; improves upon the standard features of Vi and, at the same time, allows +;; full access to all Emacs facilities. Viper supports multiple undo, +;; file name completion, command, file, and search history and it extends +;; Vi in many other ways. Viper is highly customizable through the various +;; hooks, user variables, and keymaps. It is implemented as a collection +;; of minor modes and it is designed to provide full access to all Emacs +;; major and minor modes. +;; +;;; History: +;; +;; Viper is a new name for a package formerly known as VIP-19, +;; which was a successor of VIP version 3.5 by Masahiko Sato +;; and VIP version 4.2 by Aamod Sane +;; . Some ideas from vip 4.4.2 by Aamod Sane +;; were also shamelessly plagiarized. +;; +;; Viper maintains some degree of compatibility with these older +;; packages. See the documentation for customization. +;; +;; The main difference between Viper and these older packages are: +;; +;; 1. Viper emulates Vi at several levels, from almost complete conformity +;; to a rather loose Vi-compliance. +;; +;; 2. Viper provides full access to all major and minor modes of Emacs +;; without the need to type extra keys. +;; The older versions of VIP (and other Vi emulators) do not work with +;; some major and minor modes. +;; +;; 3. Viper supports vi-style undo. +;; +;; 4. Viper fully emulates (and improves upon) vi's replacement mode. +;; +;; 5. Viper has a better interface to ex, including command, variable, and +;; file name completion. +;; +;; 6. Viper uses native Emacs history and completion features; it doesn't +;; rely on other packages (such as gmhist.el and completer.el) to provide +;; these features. +;; +;; 7. Viper supports Vi-style editing in the minibuffer, by allowing the +;; user to switch from Insert state to Vi state to Replace state, etc. +;; +;; 8. Viper keeps history of recently inserted pieces of text and recently +;; executed Vi-style destructive commands, such as `i', `d', etc. +;; These pieces of text can be inserted in later insertion commands; +;; the previous destructive commands can be re-executed. +;; +;; 9. Viper has Vi-style keyboard macros, which enhances the similar +;; facility in the original Vi. +;; First, one can execute any Emacs command while defining a +;; macro, not just the Vi commands. Second, macros are defined in a +;; WYSYWYG mode, using an interface to Emacs' WYSIWYG style of defining +;; macros. Third, in Viper, one can define macros that are specific to +;; a given buffer, a given major mode, or macros defined for all buffers. +;; The same macro name can have several different definitions: +;; one global, several definitions for various major modes, and +;; definitions for specific buffers. +;; Buffer-specific definitions override mode-specific +;; definitions, which, in turn, override global definitions. +;; +;; +;;; Installation: +;; ------------- +;; +;; (require 'viper) +;; + +;;; Acknowledgements: +;; ----------------- +;; Bug reports and ideas contributed by many users have helped +;; improve Viper and the various versions of VIP. +;; See the on-line manual for a complete list of contributors. +;; +;; +;;; Notes: +;; +;; 1. Major modes. +;; In most cases, Viper handles major modes correctly, i.e., they come up +;; in the right state (either vi-state or emacs-state). For instance, text +;; files come up in vi-state, while, say, Dired appears in emacs-state by +;; default. +;; However, some modes do not appear in the right mode in the beginning, +;; usually because they neglect to follow Emacs conventions (e.g., they don't +;; use kill-all-local-variables when they start). Some major modes +;; may fail to come up in emacs-state if they call hooks, such as +;; text-hook, for no good reason. +;; +;; As an immediate solution, you can hit C-z to bring about the right mode. +;; An interim solution is to add an appropriate hook to the mode like this: +;; +;; (add-hook 'your-favorite-mode 'viper-mode) +;; or +;; (add-hook 'your-favorite-mode 'viper-change-state-to-emacs) +;; +;; whichever applies. The right thing to do, however, is to complain to the +;; author of the respective package. (Sometimes they also neglect to equip +;; their modes with hooks, which is one more reason for complaining.) +;; +;; 2. Keymap handling +;; Each Viper state (insert, vi, replace) is implemented as a collection of +;; several minor modes, each with its own keymap. +;; +;; Viper's Vi state consists of seven minor modes: +;; +;; viper-vi-intercept-minor-mode +;; viper-vi-local-user-minor-mode +;; viper-vi-global-user-minor-mode +;; viper-vi-kbd-minor-mode +;; viper-vi-state-modifier-minor-mode +;; viper-vi-diehard-minor-mode +;; viper-vi-basic-minor-mode +;; +;; Bindings done to the keymap of the first mode overshadow those done to +;; the second, which, in turn, overshadows those done to the third, etc. +;; +;; The last viper-vi-basic-minor-mode contains most of the usual Vi bindings +;; in its edit mode. This mode provides access to all Emacs facilities. +;; Novice users, however, may want to set their viper-expert-level to 1 +;; in their .viper file. This will enable viper-vi-diehard-minor-mode. This +;; minor mode's bindings make Viper simulate the usual Vi very closely. +;; For instance, C-c will not have its standard Emacs binding +;; and so many of the goodies of Emacs are not available. +;; +;; A skilled user should set viper-expert-level to at least 3. This will +;; enable `C-c' and many Emacs facilities will become available. +;; In this case, viper-vi-diehard-minor-mode is inactive. +;; +;; Viper gurus should have at least +;; (setq viper-expert-level 4) +;; in their ~/.viper files. This will unsuppress all Emacs keys that are not +;; essential for VI-style editing. +;; Pick-and-choose users may want to put +;; (setq viper-expert-level 5) +;; in ~/.viper. Viper will then leave it up to the user to set the variables +;; viper-want-* See viper-set-expert-level for details. +;; +;; The very first minor mode, viper-vi-intercept-minor-mode, is of no +;; concern for the user. It is needed to bind Viper's vital keys, such as +;; ESC and C-z. +;; +;; The second mode, viper-vi-local-user-minor-mode, usually has an +;; empty keymap. However, the user can set bindings in this keymap, which +;; will overshadow the corresponding bindings in the other two minor +;; modes. This is useful, for example, for setting up ZZ in gnus, +;; rmail, mh-e, etc., to send message instead of saving it in a file. +;; Likewise, in Dired mode, you may want to bind ZN and ZP to commands +;; that would visit the next or the previous file in the Dired buffer. +;; Setting local keys is tricky, so don't do it directly. Instead, use +;; viper-add-local-keys function (see its doc). +;; +;; The third minor mode, viper-vi-global-user-minor-mode, is also intended +;; for the users but, unlike viper-vi-local-user-minor-mode, its key +;; bindings are seen in all Viper buffers. This mode keys can be done +;; with define-key command. +;; +;; The fourth minor mode, viper-vi-kbd-minor-mode, is used by keyboard +;; macros. Users are NOT supposed to modify this keymap directly. +;; +;; The fifth mode, viper-vi-state-modifier-minor-mode, can be used to set +;; key bindings that are visible in some major modes but not in others. +;; +;; Users are allowed to modify keymaps that belong to +;; viper-vi-local-user-minor-mode, viper-vi-global-user-minor-mode, +;; and viper-vi-state-modifier-minor-mode only. +;; +;; Viper's Insert state also has seven minor modes: +;; +;; viper-insert-intercept-minor-mode +;; viper-insert-local-user-minor-mode +;; viper-insert-global-user-minor-mode +;; viper-insert-kbd-minor-mode +;; viper-insert-state-modifier-minor-mode +;; viper-insert-diehard-minor-mode +;; viper-insert-basic-minor-mode +;; +;; As with VI's editing modes, the first mode, +;; viper-insert-intercept-minor-mode is used to bind vital keys that are not +;; to be changed by the user. +;; +;; The next mode, viper-insert-local-user-minor-mode, is used to customize +;; bindings in the insert state of Viper. The third mode, +;; viper-insert-global-user-minor-mode is like +;; viper-insert-local-user-minor-mode, except that its bindings are seen in +;; all Viper buffers. As with viper-vi-local-user-minor-mode, its bindings +;; should be done via the function viper-add-local-keys. Bindings for +;; viper-insert-global-user-minor-mode can be set with the define-key command. +;; +;; The next minor mode, viper-insert-kbd-minor-mode, +;; is used for keyboard VI-style macros defined with :map!. +;; +;; The fifth minor mode, viper-insert-state-modifier-minor-mode, is like +;; viper-vi-state-modifier-minor-mode, except that it is used in the Insert +;; state; it can be used to modify keys in a mode-specific fashion. +;; +;; The minor mode viper-insert-diehard-minor-mode is in effect when +;; the user wants a high degree of Vi compatibility (a bad idea, really!). +;; The last minor mode, viper-insert-basic-minor-mode, is always in effect +;; when Viper is in insert state. It binds a small number of keys needed for +;; Viper's operation. +;; +;; Finally, Viper provides minor modes for overriding bindings set by Emacs +;; modes when Viper is in Emacs state: +;; +;; viper-emacs-local-user-minor-mode +;; viper-emacs-global-user-minor-mode +;; viper-emacs-kbd-minor-mode +;; viper-emacs-state-modifier-minor-mode +;; +;; These minor modes are in effect when Viper is in Emacs state. The keymap +;; associated with viper-emacs-global-user-minor-mode, +;; viper-emacs-global-user-map, overrides the global and local keymaps as +;; well as the minor mode keymaps set by other modes. The keymap of +;; viper-emacs-local-user-minor-mode, viper-emacs-local-user-map, overrides +;; everything, but it is used on a per buffer basis. +;; The keymap associated with viper-emacs-state-modifier-minor-mode +;; overrides keys on a per-major-mode basis. The mode +;; viper-emacs-kbd-minor-mode is used to define Vi-style macros in Emacs +;; state. +;; +;; 3. There is also one minor mode that is used when Viper is in its +;; replace-state (used for commands like cw, C, etc.). This mode is +;; called +;; +;; viper-replace-minor-mode +;; +;; and its keymap is viper-replace-map. Replace minor mode is always +;; used in conjunction with the minor modes for insert-state, and its +;; keymap overshadows the keymaps for insert minor modes. +;; +;; 4. Defining buffer-local bindings in Vi and Insert modes. +;; As mentioned before, sometimes, it is convenient to have +;; buffer-specific of mode-specific key bindings in Vi and insert modes. +;; Viper provides a special function, viper-add-local-keys, to do precisely +;; this. For instance, is you need to add couple of mode-specific bindings +;; to Insert mode, you can put +;; +;; (viper-add-local-keys 'insert-state '((key1 . func1) (key2 .func2))) +;; +;; somewhere in a hook of this major mode. If you put something like this +;; in your own elisp function, this will define bindings specific to the +;; buffer that was current at the time of the call to viper-add-local-keys. +;; The only thing to make sure here is that the major mode of this buffer +;; is written according to Emacs conventions, which includes a call to +;; (kill-all-local-variables). See viper-add-local-keys for more details. +;; +;; +;; TO DO (volunteers?): +;; +;; 1. Some of the code that is inherited from VIP-3.5 is rather +;; convoluted. Instead of viper-command-argument, keymaps should bind the +;; actual commands. E.g., "dw" should be bound to a generic command +;; viper-delete that will delete things based on the value of +;; last-command-event. This would greatly simplify the logic and the code. +;; +;; 2. Somebody should venture to write a customization package a la +;; options.el that would allow the user to change values of variables +;; that meet certain specs (e.g., match a regexp) and whose doc string +;; starts with a '*'. Then, the user should be offered to save +;; variables that were changed.
