8 ;; Author: Neal Ziring <nz@rsch.wisc.edu>
9 ;; Felix S. T. Wu <wu@crys.wisc.edu>
10 ;; Keywords: emulations
14 ;; Originally written by : seismo!wucs!nz@rsch.wisc.edu (Neal Ziring)
15 ;; Extensively redesigned and rewritten by wu@crys.wisc.edu (Felix S.T. Wu)
16 ;; Last revision: 01/07/87 Wed (for GNU Emacs 18.33)
18 ;; INSTALLATION PROCEDURE:
19 ;; 1) Add a global key binding for command "vi-mode" (I use ESC ESC instead of
20 ;; the single ESC used in real "vi", so I can access other ESC prefixed emacs
21 ;; commands while I'm in "vi"), say, by putting the following line in your
23 ;; (define-key global-map "\e\e" 'vi-mode) ;quick switch into vi-mode
24 ;; 2) If you wish you can define "find-file-hook" to enter "vi" automatically
25 ;; after a file is loaded into the buffer. For example, I defined it as:
26 ;; (setq find-file-hook (list
27 ;; (function (lambda ()
28 ;; (if (not (or (eq major-mode 'Info-mode)
29 ;; (eq major-mode 'vi-mode)))
31 ;; 3) In your .emacs file you can define the command "vi-mode" to be "autoload"
32 ;; or you can execute the "load" command to load "vi" directly.
33 ;; 4) Read the comments for command "vi-mode" before you start using it.
36 ;; 1). A general 'define-operator' function to replace current hack
37 ;; 2). In operator handling, should allow other point moving Emacs commands
38 ;; (such as ESC <, ESC >) to be used as arguments.

410 "Major mode that acts like the `vi' editor.
411 The purpose of this mode is to provide you the combined power of vi (namely,
412 the \"cross product\" effect of commands and repeat last changes) and Emacs.
414 This command redefines nearly all keys to look like vi commands.
415 It records the previous major mode, and any vi command for input
416 \(`i', `a', `s', etc.) switches back to that mode.
417 Thus, ordinary Emacs (in whatever major mode you had been using)
418 is \"input\" mode as far as vi is concerned.
420 To get back into vi from \"input\" mode, you must issue this command again.
421 Therefore, it is recommended that you assign it to a key.
423 Major differences between this mode and real vi :
425 * Limitations and unsupported features
426 - Search patterns with line offset (e.g. /pat/+3 or /pat/z.) are
428 - Ex commands are not implemented; try ':' to get some hints.
429 - No line undo (i.e. the 'U' command), but multi-undo is a standard feature.
432 - The stopping positions for some point motion commands (word boundary,
433 pattern search) are slightly different from standard 'vi'.
434 Also, no automatic wrap around at end of buffer for pattern searching.
435 - Since changes are done in two steps (deletion then insertion), you need
436 to undo twice to completely undo a change command. But this is not needed
437 for undoing a repeated change command.
438 - No need to set/unset 'magic', to search for a string with regular expr
439 in it just put a prefix arg for the search commands. Replace cmds too.
440 - ^R is bound to incremental backward search, so use ^L to redraw screen.
443 - Some standard (or modified) Emacs commands were integrated, such as
444 incremental search, query replace, transpose objects, and keyboard macros.
445 - In command state, ^X links to the 'ctl-x-map', and ESC can be linked to
446 esc-map or set undefined. These can give you the full power of Emacs.
447 - See vi-com-map for those keys that are extensions to standard vi, e.g.
448 `vi-name-last-change-or-macro', `vi-verify-spelling', `vi-locate-def',
449 `vi-mark-region', and 'vi-quote-words'. Some of them are quite handy.
450 - Use \\[vi-switch-mode] to switch among different modes quickly.
452 Syntax table and abbrevs while in vi mode remain as they were in Emacs."
