29 1. Key mapping *key-mapping* *mapping* *macro*
|
|
|
30
|
|
|
31 Key mapping is used to change the meaning of typed keys. The most common use
|
|
|
32 is to define a sequence commands for a function key. Example: >
|
|
|
33
|
|
|
34 :map <F2> a<C-R>=strftime("%c")<CR><Esc>
|
|
|
35
|
|
236
|
36 This appends the current date and time after the cursor (in <> notation |<>|).

39 1.1 MAP COMMANDS *:map-commands*
|
|
|
40
|
|
7
|
41 There are commands to enter new mappings, remove mappings and list mappings.
|
|
|
42 See |map-overview| for the various forms of "map" and their relationships with
|
|
|
43 modes.
|
|
|
44
|
|
|
45 {lhs} means left-hand-side *{lhs}*
|
|
|
46 {rhs} means right-hand-side *{rhs}*

57 :cm[ap] {lhs} {rhs} |mapmode-c| *:cm* *:cmap*
|
|

|
58 Map the key sequence {lhs} to {rhs} for the modes
|
|
|
59 where the map command applies. The result, including
|
|
|
60 {rhs}, is then further scanned for mappings. This
|
|
|
61 allows for nested and recursive use of mappings.

|
|
7
|
74 Map the key sequence {lhs} to {rhs} for the modes
|
|
|
75 where the map command applies. Disallow mapping of
|
|
|
76 {rhs}, to avoid nested and recursive mappings. Often
|
|
|
77 used to redefine a command. {not in Vi}

90 Remove the mapping of {lhs} for the modes where the

91 map command applies. The mapping may remain defined
|
|
|
92 for other modes where it applies.
|
|
|
93 Note: Trailing spaces are included in the {lhs}. This
|
|
|
94 unmap does NOT work: >

|
136 List the key mappings for the key sequences starting
|
|
|
137 with {lhs} in the modes where the map command applies.
|
|
|
138 {not in Vi}
|
|
|
139
|
|
|
140 These commands are used to map a key or key sequence to a string of
|
|
|
141 characters. You can use this to put command sequences under function keys,
|
|
|
142 translate one key into another, etc. See |:mkexrc| for how to save and
|
|
|
143 restore the current mappings.
|
|
|
144
|
|
592
|
145 *map-ambiguous*
|
|
|
146 When two mappings start with the same sequence of characters, they are
|
|
|
147 ambiguous. Example: >
|
|
|
148 :imap aa foo
|
|
|
149 :imap aaa bar
|
|
|
150 When Vim has read "aa", it will need to get another character to be able to
|
|
|
151 decide if "aa" or "aaa" should be mapped. This means that after typing "aa"
|
|
|
152 that mapping won't get expanded yet, Vim is waiting for another character.
|
|
|
153 If you type a space, then "foo" will get inserted, plus the space. If you
|
|
|
154 type "a", then "bar" will get inserted.
|
|
|
155 {Vi does not allow ambiguous mappings}
|
|
|
156
|
|
|
157
|
|
|
158 1.2 SPECIAL ARGUMENTS *:map-arguments*
|
|
|
159
|
|
721
|
160 "<buffer>", "<silent>", "<script>", "<expr>" and "<unique>" can be used in any
|
|
|
161 order. They must appear right after the command, before any other arguments.
|
|
|
162
|
|
7
|
163 *:map-local* *:map-<buffer>* *E224* *E225*
|
|
|
164 If the first argument to one of these commands is "<buffer>" it will apply to
|
|
|
165 mappings locally to the current buffer only. Example: >
|
|
|
166 :map <buffer> ,w /[.,;]<CR>
|
|
|
167 Then you can map ",w" to something else in another buffer: >
|
|
|
168 :map <buffer> ,w /[#&!]<CR>
|
|
|
169 The local buffer mappings are used before the global ones.
|
|
|
170 The "<buffer>" argument can also be used to clear mappings: >
|
|
|
171 :unmap <buffer> ,w
|
|
|
172 :mapclear <buffer>
|
|
|
173 Local mappings are also cleared when a buffer is deleted, but not when it is
|
|
|
174 unloaded. Just like local option values.
|
|
|
175
|
|
|
176 *:map-<silent>* *:map-silent*
|
|
|
177 To define a mapping which will not be echoed on the command line, add
|
|
|
178 "<silent>" as the first argument. Example: >
|
|
|
179 :map <silent> ,h /Header<CR>
|
|
|
180 The search string will not be echoed when using this mapping. Messages from
|
|
|
181 the executed command are still given though. To shut them up too, add a
|
|
|
182 ":silent" in the executed command: >
|
|
|
183 :map <silent> ,h :exe ":silent normal /Header\r"<CR>
|
|
|
184 Prompts will still be given, e.g., for inputdialog().
|
|
|
185 Using "<silent>" for an abbreviation is possible, but will cause redrawing of
|
|
|
186 the command line to fail.
|
|
|
187
|
|
|
188 *:map-<script>* *:map-script*
|
|
|
189 If the first argument to one of these commands is "<script>" and it is used to
|
|
|
190 define a new mapping or abbreviation, the mapping will only remap characters
|
|
|
191 in the {rhs} using mappings that were defined local to a script, starting with
|
|
|
192 "<SID>". This can be used to avoid that mappings from outside a script
|
|
|
193 interfere (e.g., when CTRL-V is remapped in mswin.vim), but do use other
|
|
|
194 mappings defined in the script.
|
|
|
195 Note: ":map <script>" and ":noremap <script>" do the same thing. The
|
|
|
196 "<script>" overrules the command name. Using ":noremap <script>" is
|
|
|
197 preferred, because it's clearer that remapping is (mostly) disabled.
|
|
|
198
|
|
|
199 *:map-<unique>* *E226* *E227*
|
|
|
200 If the first argument to one of these commands is "<unique>" and it is used to
|
|
|
201 define a new mapping or abbreviation, the command will fail if the mapping or
|
|
|
202 abbreviation already exists. Example: >
|
|
|
203 :map <unique> ,w /[#&!]<CR>
|
|
|
204 When defining a local mapping, there will also be a check if a global map
|
|
|
205 already exists which is equal.
|
|
|
206 Example of what will fail: >
|
|
|
207 :map ,w /[#&!]<CR>
|
|
|
208 :map <buffer> <unique> ,w /[.,;]<CR>
|
|
626
|
209 If you want to map a key and then have it do what it was originally mapped to,
|
|
|
210 have a look at |maparg()|.
|
|
7
|
211
|
|
721
|
212 *:map-<expr>* *:map-expression*
|
|
|
213 If the first argument to one of these commands is "<expr>" and it is used to
|
|
|
214 define a new mapping or abbreviation, the argument is an expression. The
|
|
|
215 expression is evaluated to obtain the {rhs} that is used. Example: >
|
|
|
216 :inoremap <expr> . InsertDot()
|
|
|
217 The result of the InsertDot() function will be inserted. It could check the
|
|
|
218 text before the cursor and start omni completion when some condition is met.
|
|
|
219
|
|
|
220 Be very careful about side effects! The expression is evaluated while
|
|
|
221 obtaining characters, if you change buffer text, move the cursor, edit another
|
|
843
|
222 file, etc. you may very well make command dysfunctional.
|
|
721
|
223
|
|
|
224 Here is an example that inserts a list number that increases: >
|
|
|
225 let counter = 0
|
|
|
226 inoremap <expr> <C-L> ListItem()
|
|
|
227 inoremap <expr> <C-R> ListReset()
|
|
|
228
|
|
|
229 func ListItem()
|
|
|
230 let g:counter += 1
|
|
|
231 return g:counter . '. '
|
|
|
232 endfunc
|
|
|
233
|
|
|
234 func ListReset()
|
|
|
235 let g:counter = 0
|
|
|
236 return ''
|
|
|
237 endfunc
|
|
|
238
|
|
727
|
239 CTRL-L inserts the next number, CTRL-R resets the count. CTRL-R returns an
|
|
721
|
240 empty string, so that nothing is inserted.
|
|
7
|
241
|
|
837
|
242 Note that there are some tricks to make special keys work and escape CSI bytes
|
|
|
243 in the text. The |:map| command also does this, thus you must avoid that it
|
|
|
244 is done twice. This does not work: >
|
|
|
245 :imap <expr> <F3> "<Char-0x611B>"
|
|
|
246 Because the <Char- sequence is escaped for being a |:imap| argument and then
|
|
|
247 again for using <expr>. This does work: >
|
|
|
248 :imap <expr> <F3> "\u611B"
|
|
|
249 Using 0x80 as a single byte before other text does not work, it will be seen
|
|
|
250 as a special key.
|
|
|

|
253 1.3 MAPPING AND MODES *:map-modes*
|
|
7
|
254
|
|
|
255 There are five sets of mappings
|
|
|
256 - For Normal mode: When typing commands.
|
|
|
257 - For Visual mode: When typing commands while the Visual area is highlighted.
|
|
|
258 - For Operator-pending mode: When an operator is pending (after "d", "y", "c",
|
|
|
259 etc.). Example: ":omap { w" makes "y{" work like "yw" and "d{" like "dw".
|
|
236
|
260 - For Insert mode. These are also used in Replace mode.
|
|
7
|
261 - For Command-line mode: When entering a ":" or "/" command.
|
|
|
262
|
|
|
263 Special case: While typing a count for a command in Normal mode, mapping zero
|
|
|
264 is disabled. This makes it possible to map zero without making it impossible
|
|
|
265 to type a count with a zero.

|
|
|
300 The original Vi did not have separate mappings for
|
|
|
301 Normal/Visual/Operator-pending mode and for Insert/Command-line mode.
|
|
|
302 Therefore the ":map" and ":map!" commands enter and display mappings for
|
|
|
303 several modes. In Vim you can use the ":nmap", ":vmap", ":omap", ":cmap" and
|
|
|
304 ":imap" commands to enter mappings for each mode separately.
|
|
|
305
|
|
|
306 To enter a mapping for Normal and Visual mode, but not Operator-pending mode,
|
|
|
307 first define it for all three modes, then unmap it for Operator-pending mode:
|
|
|
308 :map xx something-difficult
|
|
|
309 :ounmap xx
|
|
|
310 Likewise for a mapping for Visual and Operator-pending mode or Normal and
|
|
|
311 Operator-pending mode.
|
|
|
312
|
|
|
313 *language-mapping*
|
|
|
314 ":lmap" defines a mapping that applies to:
|
|
|
315 - Insert mode
|
|
|
316 - Command-line mode
|
|
|
317 - when entering a search pattern
|
|
|
318 - the argument of the commands that accept a text character, such as "r" and
|
|
|
319 "f"
|
|
|
320 - for the input() line
|
|
|
321 Generally: Whenever a character is to be typed that is part of the text in the
|
|
|
322 buffer, not a Vim command character. "Lang-Arg" isn't really another mode,
|
|
|
323 it's just used here for this situation.
|
|
|
324 The simplest way to load a set of related language mappings is by using the
|
|
|
325 'keymap' option. See |45.5|.
|
|
|
326 In Insert mode and in Command-line mode the mappings can be disabled with
|
|
|
327 the CTRL-^ command |i_CTRL-^| |c_CTRL-^|. When starting to enter a normal
|
|
|
328 command line (not a search pattern) the mappings are disabled until a CTRL-^
|
|
|
329 is typed. The state last used is remembered for Insert mode and Search
|
|
|
330 patterns separately. The state for Insert mode is also used when typing a
|
|
|
331 character as an argument to command like "f" or "t".
|
|
|
332 Language mappings will never be applied to already mapped characters. They
|
|
|
333 are only used for typed characters. This assumes that the language mapping
|
|
|
334 was already done when typing the mapping.

337 1.4 LISTING MAPPINGS *map-listing*
|
|
|
338
|
|
7
|
339 When listing mappings the characters in the first two columns are:
|
|
|
340
|
|
|
341 CHAR MODE ~
|
|
|
342 <Space> Normal, Visual and Operator-pending
|
|
|
343 n Normal
|
|
|
344 v Visual
|
|
|
345 o Operator-pending
|
|
|
346 ! Insert and Command-line
|
|
|
347 i Insert
|
|
|
348 l ":lmap" mappings for Insert, Command-line and Lang-Arg
|
|
|
349 c Command-line
|
|
|
350
|
|
|
351 Just before the {rhs} a special character can appear:
|
|
|
352 * indicates that it is not remappable
|
|
|
353 & indicates that only script-local mappings are remappable
|
|
|
354 @ indicates a buffer-local mapping
|
|
|
355
|
|
|
356 Everything from the first non-blank after {lhs} up to the end of the line
|
|
|
357 (or '|') is considered to be part of {rhs}. This allows the {rhs} to end
|
|
|
358 with a space.
|
|
|
359
|
|
|
360 Note: When using mappings for Visual mode, you can use the "'<" mark, which
|
|
|
361 is the start of the last selected Visual area in the current buffer |'<|.
|
|
|
362
|
|
481
|
363 *:map-verbose*
|
|
|
364 When 'verbose' is non-zero, listing a key map will also display where it was
|
|
|
365 last defined. Example: >
|
|
|
366
|
|
|
367 :verbose map <C-W>*
|
|
|
368 n <C-W>* * <C-W><C-S>*
|
|
|
369 Last set from /home/abcd/.vimrc
|
|
|
370
|
|
483
|
371 See |:verbose-cmd| for more information.

|
374 1.5 MAPPING SPECIAL KEYS *:map-special-keys*
|
|
|
375
|
|
|
376 There are three ways to map a special key:
|
|
|
377 1. The Vi-compatible method: Map the key code. Often this is a sequence that
|
|
|
378 starts with <Esc>. To enter a mapping like this you type ":map " and then
|
|
|
379 you have to type CTRL-V before hitting the function key. Note that when
|
|
|
380 the key code for the key is in the termcap (the t_ options), it will
|
|
|
381 automatically be translated into the internal code and become the second
|
|
|
382 way of mapping (unless the 'k' flag is included in 'cpoptions').
|
|
|
383 2. The second method is to use the internal code for the function key. To
|
|
|
384 enter such a mapping type CTRL-K and then hit the function key, or use
|
|
|
385 the form "#1", "#2", .. "#9", "#0", "<Up>", "<S-Down>", "<S-F7>", etc.
|
|
|
386 (see table of keys |key-notation|, all keys from <Up> can be used). The
|
|
|
387 first ten function keys can be defined in two ways: Just the number, like
|
|
|
388 "#2", and with "<F>", like "<F2>". Both stand for function key 2. "#0"
|
|
|
389 refers to function key 10, defined with option 't_f10', which may be
|
|
|
390 function key zero on some keyboards. The <> form cannot be used when
|
|
|
391 'cpoptions' includes the '<' flag.
|
|
|
392 3. Use the termcap entry, with the form <t_xx>, where "xx" is the name of the
|
|
|
393 termcap entry. Any string entry can be used. For example: >
|
|
|
394 :map <t_F3> G
|
|
|
395 < Maps function key 13 to "G". This does not work if 'cpoptions' includes
|
|
|
396 the '<' flag.
|
|
|
397
|
|
|
398 The advantage of the second and third method is that the mapping will work on
|
|
|
399 different terminals without modification (the function key will be
|
|
|
400 translated into the same internal code or the actual key code, no matter what
|
|
|
401 terminal you are using. The termcap must be correct for this to work, and you
|
|
|
402 must use the same mappings).
|
|
|
403
|
|
|
404 DETAIL: Vim first checks if a sequence from the keyboard is mapped. If it
|
|
|
405 isn't the terminal key codes are tried (see |terminal-options|). If a
|
|
|
406 terminal code is found it is replaced with the internal code. Then the check
|
|
|
407 for a mapping is done again (so you can map an internal code to something
|
|
|
408 else). What is written into the script file depends on what is recognized.
|
|
|
409 If the terminal key code was recognized as a mapping the key code itself is
|
|
|
410 written to the script file. If it was recognized as a terminal code the
|
|
|
411 internal code is written to the script file.
|
|
|
412
|
|
|
413
|
|
|
414 1.6 SPECIAL CHARACTERS *:map-special-chars*
|
|
7
|
415 *map_backslash*
|
|
|
416 Note that only CTRL-V is mentioned here as a special character for mappings
|
|
|
417 and abbreviations. When 'cpoptions' does not contain 'B', a backslash can
|
|
|
418 also be used like CTRL-V. The <> notation can be fully used then |<>|. But
|
|
|
419 you cannot use "<C-V>" like CTRL-V to escape the special meaning of what
|
|
|
420 follows.
|
|
|
421
|
|
|
422 To map a backslash, or use a backslash literally in the {rhs}, the special
|
|
|
423 sequence "<Bslash>" can be used. This avoids the need to double backslashes
|
|
|
424 when using nested mappings.
|
|
|
425
|
|
532
|
426 *map_CTRL-C*
|
|
|
427 Using CTRL-C in the {lhs} is possible, but it will only work when Vim is
|
|
|
428 waiting for a key, not when Vim is busy with something. When Vim is busy
|
|
|
429 CTRL-C interrupts/breaks the command.
|
|
|
430 When using the GUI version on MS-Windows CTRL-C can be mapped to allow a Copy
|
|
|
431 command to the clipboard. Use CTRL-Break to interrupt Vim.
|
|
7
|
432
|
|
|
433 *map_space_in_lhs*
|
|
|
434 To include a space in {lhs} precede it with a CTRL-V (type two CTRL-Vs for
|
|
|
435 each space).
|
|
|
436 *map_space_in_rhs*
|
|
|
437 If you want a {rhs} that starts with a space, use "<Space>". To be fully Vi
|
|
|
438 compatible (but unreadable) don't use the |<>| notation, precede {rhs} with a
|
|
|
439 single CTRL-V (you have to type CTRL-V two times).
|
|
|
440 *map_empty_rhs*
|
|
|
441 You can create an empty {rhs} by typing nothing after a single CTRL-V (you
|
|
|
442 have to type CTRL-V two times). Unfortunately, you cannot do this in a vimrc
|
|
|
443 file.
|
|
|
444 *<Nop>*
|
|
|
445 A easier way to get a mapping that doesn't produce anything, is to use "<Nop>"
|
|
|
446 for the {rhs}. This only works when the |<>| notation is enabled. For
|
|
|
447 example, to make sure that function key 8 does nothing at all: >
|
|
|
448 :map <F8> <Nop>
|
|
|
449 :map! <F8> <Nop>
|
|
|
450 <
|
|
592
|
451 *map-multibyte*
|
|
|
452 It is possible to map multibyte characters, but only the whole character. You
|
|
|
453 cannot map the first byte only. This was done to prevent problems in this
|
|
|
454 scenario: >
|
|
|
455 :set encoding=latin1
|
|
|
456 :imap <M-C> foo
|
|
|
457 :set encoding=utf-8
|
|
|
458 The mapping for <M-C> is defined with the latin1 encoding, resulting in a 0xc3
|
|
|
459 byte. If you type the character á (0xea <M-a>) in UTF-8 encoding this is the
|
|
|
460 two bytes 0xc3 0xa1. You don't want the 0xc3 byte to be mapped then,
|
|
|
461 otherwise it would be impossible to type the á character.
|
|
|
462
|
|
7
|
463 *<Leader>* *mapleader*
|
|
|
464 To define a mapping which uses the "mapleader" variable, the special string
|
|
|
465 "<Leader>" can be used. It is replaced with the string value of "mapleader".
|
|
|
466 If "mapleader" is not set or empty, a backslash is used instead. Example: >
|
|
|
467 :map <Leader>A oanother line<Esc>
|
|
|
468 Works like: >
|
|
|
469 :map \A oanother line<Esc>
|
|
|
470 But after: >
|
|
|
471 :let mapleader = ","
|
|
|
472 It works like: >
|
|
|
473 :map ,A oanother line<Esc>
|
|
|
474
|
|
|
475 Note that the value of "mapleader" is used at the moment the mapping is
|
|
|
476 defined. Changing "mapleader" after that has no effect for already defined
|
|
|
477 mappings.
|
|
|
478
|
|
|
479 *<LocalLeader>* *maplocalleader*
|
|
|
480 Just like <Leader>, except that it uses "maplocalleader" instead of
|
|
|
481 "mapleader". <LocalLeader> is to be used for mappings which are local to a
|
|
|
482 buffer. Example: >
|
|
|
483 :map <LocalLeader>q \DoItNow
|
|
|
484 <
|
|
|
485 In a global plugin <Leader> should be used and in a filetype plugin
|
|
|
486 <LocalLeader>. "mapleader" and "maplocalleader" can be equal. Although, if
|
|
|
487 you make them different, there is a smaller chance of mappings from global
|
|
|
488 plugins to clash with mappings for filetype plugins. For example, you could
|
|
|
489 keep "mapleader" at the default backslash, and set "maplocalleader" to an
|
|
|
490 underscore.
|
|
|
491
|
|
|
492 *map-<SID>*
|
|
|
493 In a script the special key name "<SID>" can be used to define a mapping
|
|
|
494 that's local to the script. See |<SID>| for details.
|
|
|
495
|
|
|
496 *<Plug>*
|
|
|
497 The special key name "<Plug>" can be used for an internal mapping, which is
|
|
|
498 not to be matched with any key sequence. This is useful in plugins
|
|
|
499 |using-<Plug>|.
|
|
|
500
|
|
|
501 *<Char>* *<Char->*
|
|
|
502 To map a character by its decimal, octal or hexadecimal number the <Char>
|
|
|
503 construct can be used:
|
|
|
504 <Char-123> character 123
|
|
|
505 <Char-033> character 27
|
|
|
506 <Char-0x7f> character 127
|
|
|
507 This is useful to specify a (multi-byte) character in a 'keymap' file.
|
|
|
508 Upper and lowercase differences are ignored.
|
|
|
509
|
|
|
510 *map-comments*
|
|
|
511 It is not possible to put a comment after these commands, because the '"'
|
|
|
512 character is considered to be part of the {lhs} or {rhs}.
|
|
|
513
|
|
|
514 *map_bar*
|
|
|
515 Since the '|' character is used to separate a map command from the next
|
|
|
516 command, you will have to do something special to include a '|' in {rhs}.
|
|
|
517 There are three methods:
|
|
|
518 use works when example ~
|
|
|
519 <Bar> '<' is not in 'cpoptions' :map _l :!ls <Bar> more^M
|
|
|
520 \| 'b' is not in 'cpoptions' :map _l :!ls \| more^M
|
|
|
521 ^V| always, in Vim and Vi :map _l :!ls ^V| more^M
|
|
|
522
|
|
|
523 (here ^V stands for CTRL-V; to get one CTRL-V you have to type it twice; you
|
|
|
524 cannot use the <> notation "<C-V>" here).
|
|
|
525
|
|
|
526 All three work when you use the default setting for 'cpoptions'.
|
|
|
527
|
|
|
528 When 'b' is present in 'cpoptions', "\|" will be recognized as a mapping
|
|
|
529 ending in a '\' and then another command. This is Vi compatible, but
|
|
|
530 illogical when compared to other commands.
|
|
|
531
|
|
|
532 *map_return*
|
|
|
533 When you have a mapping that contains an Ex command, you need to put a line
|
|
|
534 terminator after it to have it executed. The use of <CR> is recommended for
|
|
|
535 this (see |<>|). Example: >
|
|
|
536 :map _ls :!ls -l %<CR>:echo "the end"<CR>
|
|
|
537
|
|
|
538 To avoid mapping of the characters you type in insert or Command-line mode,
|
|
|
539 type a CTRL-V first. The mapping in Insert mode is disabled if the 'paste'
|
|
|
540 option is on.
|
|
|
541
|
|
|
542 Note that when an error is encountered (that causes an error message or beep)
|
|
|
543 the rest of the mapping is not executed. This is Vi-compatible.
|
|
|
544
|
|
|
545 Note that the second character (argument) of the commands @zZtTfF[]rm'`"v
|
|
|
546 and CTRL-X is not mapped. This was done to be able to use all the named
|
|
|
547 registers and marks, even when the command with the same name has been
|
|
|
548 mapped.
|
|
|

551 1.7 WHAT KEYS TO MAP *map-which-keys*
|
|
|
552
|
|
7
|
553 If you are going to map something, you will need to choose which key(s) to use
|
|
|
554 for the {lhs}. You will have to avoid keys that are used for Vim commands,
|
|
|
555 otherwise you would not be able to use those commands anymore. Here are a few
|
|
|
556 suggestions:
|
|
|
557 - Function keys <F2>, <F3>, etc.. Also the shifted function keys <S-F1>,
|
|
|
558 <S-F2>, etc. Note that <F1> is already used for the help command.
|
|
588
|
559 - Meta-keys (with the ALT key pressed). |:map-alt-keys|
|
|
7
|
560 - Use the '_' or ',' character and then any other character. The "_" and ","
|
|
|
561 commands do exist in Vim (see |_| and |,|), but you probably never use them.
|
|
|
562 - Use a key that is a synonym for another command. For example: CTRL-P and
|
|
|
563 CTRL-N. Use an extra character to allow more mappings.
|
|
|
564
|
|
|
565 See the file "index" for keys that are not used and thus can be mapped without
|
|
|
566 losing any builtin function. You can also use ":help {key}^D" to find out if
|
|
|
567 a key is used for some command. ({key} is the specific key you want to find
|
|
|
568 out about, ^D is CTRL-D).
|
|

|
571 1.8 EXAMPLES *map-examples*
|
|
|
572
|
|
7
|
573 A few examples (given as you type them, for "<CR>" you type four characters;
|
|
|
574 the '<' flag must not be present in 'cpoptions' for this to work). >
|
|
|
575
|
|
|
576 :map <F3> o#include
|
|
|
577 :map <M-g> /foo<CR>cwbar<Esc>
|

|
|
582 1.9 USING MAPPINGS *map-typing*
|
|
|
583
|
|
7
|
584 Vim will compare what you type with the start of a mapped sequence. If there
|
|
|
585 is an incomplete match, it will get more characters until there either is a
|
|
|
586 complete match or until there is no match at all. Example: If you map! "qq",
|
|
|
587 the first 'q' will not appear on the screen until you type another
|
|
|
588 character. This is because Vim cannot know if the next character will be a
|
|
|
589 'q' or not. If the 'timeout' option is on (which is the default) Vim will
|
|
|
590 only wait for one second (or as long as specified with the 'timeoutlen'
|
|
|
591 option). After that it assumes that the 'q' is to be interpreted as such. If
|
|
|
592 you type slowly, or your system is slow, reset the 'timeout' option. Then you
|
|
|
593 might want to set the 'ttimeout' option.
|
|
|
594
|
|
|
595 *map-keys-fails*
|
|
588
|
596 There are situations where key codes might not be recognized:
|
|
7
|
597 - Vim can only read part of the key code. Mostly this is only the first
|
|
|
598 character. This happens on some Unix versions in an xterm.
|
|
|
599 - The key code is after character(s) that are mapped. E.g., "<F1><F1>" or
|
|
|
600 "g<F1>".
|
|
588
|
601
|
|
7
|
602 The result is that the key code is not recognized in this situation, and the
|
|
588
|
603 mapping fails. There are two actions needed to avoid this problem:
|
|
|
604
|
|
7
|
605 - Remove the 'K' flag from 'cpoptions'. This will make Vim wait for the rest
|
|
|
606 of the characters of the function key.
|
|
|
607 - When using <F1> to <F4> the actual key code generated may correspond to
|
|
|
608 <xF1> to <xF4>. There are mappings from <xF1> to <F1>, <xF2> to <F2>, etc.,
|
|
|
609 but these are not recognized after another half a mapping. Make sure the
|
|
|
610 key codes for <F1> to <F4> are correct: >
|
|
|
611 :set <F1>=<type CTRL-V><type F1>
|
|
|
612 < Type the <F1> as four characters. The part after the "=" must be done with
|
|
|
613 the actual keys, not the literal text.
|
|
|
614 Another solution is to use the actual key code in the mapping for the second
|
|
|
615 special key: >
|
|
|
616 :map <F1><Esc>OP :echo "yes"<CR>
|
|
|
617 Don't type a real <Esc>, Vim will recognize the key code and replace it with
|
|
|
618 <F1> anyway.
|
|
|
619
|
|
588
|
620 Another problem may be that when keeping ALT or Meta pressed the terminal
|
|
|
621 prepends ESC instead of setting the 8th bit. See |:map-alt-keys|.
|
|
|
622
|
|
7
|
623 *recursive_mapping*
|
|
|
624 If you include the {lhs} in the {rhs} you have a recursive mapping. When
|
|
|
625 {lhs} is typed, it will be replaced with {rhs}. When the {lhs} which is
|
|
|
626 included in {rhs} is encountered it will be replaced with {rhs}, and so on.
|
|
|
627 This makes it possible to repeat a command an infinite number of times. The
|
|
|
628 only problem is that the only way to stop this is by causing an error. The
|
|
|
629 macros to solve a maze uses this, look there for an example. There is one
|
|
|
630 exception: If the {rhs} starts with {lhs}, the first character is not mapped
|
|
|
631 again (this is Vi compatible).
|
|
|
632 For example: >
|
|
|
633 :map ab abcd
|
|
|
634 will execute the "a" command and insert "bcd" in the text. The "ab" in the
|
|
|
635 {rhs} will not be mapped again.
|
|
|
636
|
|
|
637 If you want to exchange the meaning of two keys you should use the :noremap
|
|
|
638 command. For example: >
|
|
|
639 :noremap k j
|
|
|
640 :noremap j k
|
|
|
641 This will exchange the cursor up and down commands.
|
|
|
642
|
|
|
643 With the normal :map command, when the 'remap' option is on, mapping takes
|
|
|
644 place until the text is found not to be a part of a {lhs}. For example, if
|
|
|
645 you use: >
|
|
|
646 :map x y
|
|
|
647 :map y x
|
|
|
648 Vim will replace x with y, and then y with x, etc. When this has happened
|
|
|
649 'maxmapdepth' times (default 1000), Vim will give the error message
|
|
|
650 "recursive mapping".
|
|
|
651
|
|
|
652 *:map-undo*
|
|
|
653 If you include an undo command inside a mapped sequence, this will bring the
|
|
|
654 text back in the state before executing the macro. This is compatible with
|
|
|
655 the original Vi, as long as there is only one undo command in the mapped
|
|
|
656 sequence (having two undo commands in a mapped sequence did not make sense
|
|
|
657 in the original Vi, you would get back the text before the first undo).
|
|
|
658
|
|
|
659
|
|
592
|
660 1.10 MAPPING ALT-KEYS *:map-alt-keys*
|
|
588
|
661
|
|
|
662 In the GUI Vim handles the Alt key itself, thus mapping keys with ALT should
|
|
|
663 always work. But in a terminal Vim gets a sequence of bytes and has to figure
|
|
|
664 out whether ALT was pressed or not.
|
|
|
665
|
|
|
666 By default Vim assumes that pressing the ALT key sets the 8th bit of a typed
|
|
605
|
667 character. Most decent terminals can work that way, such as xterm, aterm and
|
|
588
|
668 rxvt. If your <A-k> mappings don't work it might be that the terminal is
|
|
|
669 prefixing the character with an ESC character. But you can just as well type
|
|
|
670 ESC before a character, thus Vim doesn't know what happened (except for
|
|
|
671 checking the delay between characters, which is not reliable).
|
|
|
672
|
|
|
673 As of this writing, some mainstream terminals like gnome-terminal and konsole
|
|
|
674 use the ESC prefix. There doesn't appear a way to have them use the 8th bit
|
|
605
|
675 instead. Xterm should work well by default. Aterm and rxvt should work well
|
|
|
676 when started with the "--meta8" argument. You can also tweak resources like
|
|
|
677 "metaSendsEscape", "eightBitInput" and "eightBitOutput".
|
|
588
|
678
|
|
|
679 On the Linux console, this behavior can be toggled with the "setmetamode"
|
|
|
680 command. Bear in mind that not using an ESC prefix could get you in trouble
|
|
|
681 with other programs. You should make sure that bash has the "convert-meta"
|
|
|
682 option set to "on" in order for your Meta keybindings to still work on it
|
|
|
683 (it's the default readline behavior, unless changed by specific system
|
|
|
684 configuration). For that, you can add the line: >
|
|
|
685
|
|
|
686 set convert-meta on
|
|
|
687
|
|
|
688 to your ~/.inputrc file. If you're creating the file, you might want to use: >
|
|
|
689
|
|
|
690 $include /etc/inputrc
|
|
|
691
|
|
|
692 as the first line, if that file exists on your system, to keep global options.
|
|
|
693 This may cause a problem for entering special characters, such as the umlaut.
|
|
|
694 Then you should use CTRL-V before that character.
|
|
|
695
|
|
|
696 Bear in mind that convert-meta has been reported to have troubles when used in
|
|
|
697 UTF-8 locales. On terminals like xterm, the "metaSendsEscape" resource can be
|
|
|
698 toggled on the fly through the "Main Options" menu, by pressing Ctrl-LeftClick
|
|
|
699 on the terminal; that's a good last resource in case you want to send ESC when
|
|
|
700 using other applications but not when inside VIM.

|
703 1.11 MAPPING AN OPERATOR *:map-operator*
|
|
|
704
|
|
|
705 An operator is used before a {motion} command. To define your own operator
|
|
|
706 you must create mapping that first sets the 'operatorfunc' option and then
|
|
|
707 invoke the |g@| operator. After the user types the {motion} command the
|
|
|
708 specified function will be called.
|
|
|
709
|
|
626
|
710 *g@* *E774* *E775*
|
|
592
|
711 g@{motion} Call the function set by the 'operatorfunc' option.
|
|
|
712 The '[ mark is positioned at the start of the text
|
|
|
713 moved over by {motion}, the '] mark on the last
|
|
|
714 character of the text.
|
|
|
715 The function is called with one String argument:
|
|
|
716 "line" {motion} was |linewise|
|
|
|
717 "char" {motion} was |characterwise|
|
|
|
718 "block" {motion} was |blockwise-visual||
|
|
|
719 Although "block" would rarely appear, since it can
|
|
|
720 only result from Visual mode where "g@" is not useful.
|
|
|
721 {not available when compiled without the +eval
|
|
|
722 feature}
|
|
|
723
|
|
|
724 Here is an example that counts the number of spaces with <F4>: >
|
|
|
725
|
|
|
726 nmap <silent> <F4> :set opfunc=CountSpaces<CR>g@
|
|
|
727 vmap <silent> <F4> :<C-U>call CountSpaces(visualmode(), 1)<CR>
|
|
|
728
|
|
|
729 function! CountSpaces(type, ...)
|
|
|
730 let sel_save = &selection
|
|
|
731 let &selection = "inclusive"
|
|
|
732 let reg_save = @@
|
|
|
733
|
|
|
734 if a:0 " Invoked from Visual mode, use '< and '> marks.
|
|
|
735 silent exe "normal! `<" . a:type . "`>y"
|
|
|
736 elseif a:type == 'line'
|
|
|
737 silent exe "normal! '[V']y"
|
|
|
738 elseif a:type == 'block'
|
|
|
739 silent exe "normal! `[\<C-V>`]y"
|
|
|
740 else
|
|
|
741 silent exe "normal! `[v`]y"
|
|
|
742 endif
|
|
|
743
|
|
|
744 echomsg strlen(substitute(@@, '[^ ]', '', 'g'))
|
|
|
745
|
|
|
746 let &selection = sel_save
|
|
|
747 let @@ = reg_save
|
|
|
748 endfunction
|
|
|
749
|
|
|
750 Note that the 'selection' option is temporarily set to "inclusive" to be able
|
|
|
751 to yank exactly the right text by using Visual mode from the '[ to the ']
|
|
|
752 mark.
|
|
|
753
|
|
|
754 Also note that there is a separate mapping for Visual mode. It removes the
|
|
|
755 "'<,'>" range that ":" inserts in Visual mode and invokes the function with
|
|
|
756 visualmode() and an extra argument.

759 2. Abbreviations *abbreviations* *Abbreviations*
|
|
|
760
|
|
|
761 Abbreviations are used in Insert mode, Replace mode and Command-line mode.
|
|
|
762 If you enter a word that is an abbreviation, it is replaced with the word it
|
|
|
763 stands for. This can be used to save typing for often used long words. And
|
|
|
764 you can use it to automatically correct obvious spelling errors.
|
|
|
765 Examples:
|
|
|
766
|
|
|
767 :iab ms MicroSoft
|
|
|
768 :iab tihs this
|
|
|
769
|
|
|
770 There are three types of abbreviations:
|
|
|
771
|
|
|
772 full-id The "full-id" type consists entirely of keyword characters (letters
|
|
|
773 and characters from 'iskeyword' option). This is the most common
|
|
|
774 abbreviation.
|
|
|
775
|
|
|
776 Examples: "foo", "g3", "-1"
|
|
|
777
|
|
|
778 end-id The "end-id" type ends in a keyword character, but all the other
|
|
|
779 characters are not keyword characters.
|
|
|
780
|
|
|
781 Examples: "#i", "..f", "$/7"
|
|
|
782
|
|
|
783 non-id The "non-id" type ends in a non-keyword character, the other
|
|
|
784 characters may be of any type, excluding space and Tab. {this type
|
|
|
785 is not supported by Vi}
|
|
|
786
|
|
|
787 Examples: "def#", "4/7$"
|
|
|
788
|
|
|
789 Examples of strings that cannot be abbreviations: "a.b", "#def", "a b", "_$r"
|
|
|
790
|
|
|
791 An abbreviation is only recognized when you type a non-keyword character.
|
|
|
792 This can also be the <Esc> that ends insert mode or the <CR> that ends a
|
|
|
793 command. The non-keyword character which ends the abbreviation is inserted
|
|
|
794 after the expanded abbreviation. An exception to this is the character <C-]>,
|
|
|
795 which is used to expand an abbreviation without inserting any extra
|
|
|
796 characters.
|
|
|
797
|
|
|
798 Example: >
|
|
|
799 :ab hh hello
|
|
|
800 < "hh<Space>" is expanded to "hello<Space>"
|
|
|
801 "hh<C-]>" is expanded to "hello"
|
|
|
802
|
|
|
803 The characters before the cursor must match the abbreviation. Each type has
|
|
|
804 an additional rule:
|
|
|
805
|
|
|
806 full-id In front of the match is a non-keyword character, or this is where
|
|
|
807 the line or insertion starts. Exception: When the abbreviation is
|
|
|
808 only one character, it is not recognized if there is a non-keyword
|
|
|
809 character in front of it, other than a space or a <Tab>.
|
|
|
810
|
|
|
811 end-id In front of the match is a keyword character, or a space or a <Tab>,
|
|
|
812 or this is where the line or insertion starts.
|
|
|
813
|
|
|
814 non-id In front of the match is a space, <Tab> or the start of the line or
|
|
|
815 the insertion.
|
|
|
816
|
|
|
817 Examples: ({CURSOR} is where you type a non-keyword character) >
|
|
|
818 :ab foo four old otters
|
|
|
819 < " foo{CURSOR}" is expanded to " four old otters"
|
|
|
820 " foobar{CURSOR}" is not expanded
|
|
|
821 "barfoo{CURSOR}" is not expanded
|
|
|
822 >
|
|
|
823 :ab #i #include
|
|
|
824 < "#i{CURSOR}" is expanded to "#include"
|
|
|
825 ">#i{CURSOR}" is not expanded
|
|
|
826 >
|
|
42
|
827 :ab ;; <endofline>
|
|
7
|
828 < "test;;" is not expanded
|
|
|
829 "test ;;" is expanded to "test <endofline>"
|
|
|
830
|
|
|
831 To avoid the abbreviation in insert mode: Type part of the abbreviation, exit
|
|
|
832 insert mode with <Esc>, re-enter insert mode with "a" and type the rest. Or
|
|
|
833 type CTRL-V before the character after the abbreviation.
|
|
|
834 To avoid the abbreviation in Command-line mode: Type CTRL-V twice somewhere in
|
|
|
835 the abbreviation to avoid it to be replaced. A CTRL-V in front of a normal
|
|
|
836 character is mostly ignored otherwise.
|
|
|
837
|
|
|
838 It is possible to move the cursor after an abbreviation: >
|
|
|
839 :iab if if ()<Left>
|
|
|
840 This does not work if 'cpoptions' includes the '<' flag. |<>|
|
|
|
841
|
|
|
842 You can even do more complicated things. For example, to consume the space
|
|
|
843 typed after an abbreviation: >
|
|
|
844 func Eatchar(pat)
|
|
685
|
845 let c = nr2char(getchar(0))
|
|
7
|
846 return (c =~ a:pat) ? '' : c
|
|
|
847 endfunc
|
|
|
848 iabbr <silent> if if ()<Left><C-R>=Eatchar('\s')<CR>
|
|
|
849
|
|
|
850 There are no default abbreviations.
|
|
|
851
|
|
|
852 Abbreviations are never recursive. You can use ":ab f f-o-o" without any
|
|
|
853 problem. But abbreviations can be mapped. {some versions of Vi support
|
|
|
854 recursive abbreviations, for no apparent reason}
|
|
|
855
|
|
|
856 Abbreviations are disabled if the 'paste' option is on.
|
|
|
857
|
|
|
858 *:abbreviate-local* *:abbreviate-<buffer>*
|
|
|
859 Just like mappings, abbreviations can be local to a buffer. This is mostly
|
|
|
860 used in a |filetype-plugin| file. Example for a C plugin file: >
|
|
|
861 :abb <buffer> FF for (i = 0; i < ; ++i)
|
|
|
862 <
|
|
|
863 *:ab* *:abbreviate*
|
|
|
864 :ab[breviate] list all abbreviations. The character in the first
|
|
|
865 column indicates the mode where the abbreviation is
|
|
|
866 used: 'i' for insert mode, 'c' for Command-line
|
|
|
867 mode, '!' for both. These are the same as for
|
|
|
868 mappings, see |map-listing|.
|
|
|
869
|
|
502
|
870 *:abbreviate-verbose*
|
|
|
871 When 'verbose' is non-zero, listing an abbreviation will also display where it
|
|
|
872 was last defined. Example: >
|
|
|
873
|
|
|
874 :verbose abbreviate
|
|
|
875 ! teh the
|
|
|
876 Last set from /home/abcd/vim/abbr.vim
|
|
|
877
|
|
|
878 See |:verbose-cmd| for more information.
|
|
|
879
|
|
7
|
880 :ab[breviate] {lhs} list the abbreviations that start with {lhs}
|
|
|
881 You may need to insert a CTRL-V (type it twice) to
|
|
|
882 avoid that a typed {lhs} is expanded, since
|
|
|
883 command-line abbreviations apply here.
|
|
|
884
|
|
838
|
885 :ab[breviate] [<expr>] {lhs} {rhs}
|
|
7
|
886 add abbreviation for {lhs} to {rhs}. If {lhs} already
|
|
|
887 existed it is replaced with the new {rhs}. {rhs} may
|
|
|
888 contain spaces.
|
|
838
|
889 See |:map-<expr>| for the optional <expr> argument.
|
|
7
|
890
|
|
|
891 *:una* *:unabbreviate*
|
|
|
892 :una[bbreviate] {lhs} Remove abbreviation for {lhs} from the list. If none
|
|
|
893 is found, remove abbreviations in which {lhs} matches
|
|
|
894 with the {rhs}. This is done so that you can even
|
|
|
895 remove abbreviations after expansion. To avoid
|
|
|
896 expansion insert a CTRL-V (type it twice).
|
|
|
897
|
|
|
898 *:norea* *:noreabbrev*
|
|
838
|
899 :norea[bbrev] [<expr>] [lhs] [rhs]
|
|
7
|
900 same as ":ab", but no remapping for this {rhs} {not
|
|
|
901 in Vi}
|
|
|
902
|
|
|
903 *:ca* *:cabbrev*
|
|
838
|
904 :ca[bbrev] [<expr>] [lhs] [rhs]
|
|
|
905 same as ":ab", but for Command-line mode only. {not
|

|
|
908 *:cuna* *:cunabbrev*
|
|
|
909 :cuna[bbrev] {lhs} same as ":una", but for Command-line mode only. {not
|
|
|
910 in Vi}

|
912 *:cnorea* *:cnoreabbrev*
|

838
|
913 :cnorea[bbrev] [<expr>] [lhs] [rhs]

|
921 *:iuna* *:iunabbrev*
|
|

|
|
|
940 *using_CTRL-V*
|
|
|
941 It is possible to use special characters in the rhs of an abbreviation.
|
|
|
942 CTRL-V has to be used to avoid the special meaning of most non printable
|
|
|
943 characters. How many CTRL-Vs need to be typed depends on how you enter the
|
|
|
944 abbreviation. This also applies to mappings. Let's use an example here.
|
|
|
945
|
|
|
946 Suppose you want to abbreviate "esc" to enter an <Esc> character. When you
|
|
|
947 type the ":ab" command in Vim, you have to enter this: (here ^V is a CTRL-V
|
|
|
948 and ^[ is <Esc>)
|
|
|
949
|
|
|
950 You type: ab esc ^V^V^V^V^V^[
|
|
|
951
|
|
|
952 All keyboard input is subjected to ^V quote interpretation, so
|
|
|
953 the first, third, and fifth ^V characters simply allow the second,
|
|
|
954 and fourth ^Vs, and the ^[, to be entered into the command-line.
|
|
|
955
|
|
|
956 You see: ab esc ^V^V^[
|
|
|
957
|
|
|
958 The command-line contains two actual ^Vs before the ^[. This is
|
|
|
959 how it should appear in your .exrc file, if you choose to go that
|
|
|
960 route. The first ^V is there to quote the second ^V; the :ab
|
|
|
961 command uses ^V as its own quote character, so you can include quoted
|
|
42
|
962 whitespace or the | character in the abbreviation. The :ab command
|
|
7
|
963 doesn't do anything special with the ^[ character, so it doesn't need
|
|
|
964 to be quoted. (Although quoting isn't harmful; that's why typing 7
|
|
|
965 [but not 8!] ^Vs works.)
|
|
|
966
|
|
|
967 Stored as: esc ^V^[
|
|
|
968
|
|
|
969 After parsing, the abbreviation's short form ("esc") and long form
|
|
|
970 (the two characters "^V^[") are stored in the abbreviation table.
|
|
|
971 If you give the :ab command with no arguments, this is how the
|
|
|
972 abbreviation will be displayed.
|
|
|
973
|
|
|
974 Later, when the abbreviation is expanded because the user typed in
|
|
|
975 the word "esc", the long form is subjected to the same type of
|
|
|
976 ^V interpretation as keyboard input. So the ^V protects the ^[
|
|
42
|
977 character from being interpreted as the "exit Insert mode" character.
|
|
7
|
978 Instead, the ^[ is inserted into the text.
|
|
|
979
|
|
|
980 Expands to: ^[
|
|

|
985 3. Local mappings and functions *script-local*
|
|
|
986
|
|
|
987 When using several Vim script files, there is the danger that mappings and
|
|
|
988 functions used in one script use the same name as in other scripts. To avoid
|
|
|
989 this, they can be made local to the script.
|
|
|
990
|
|
|
991 *<SID>* *<SNR>* *E81*
|
|
|
992 The string "<SID>" can be used in a mapping or menu. This requires that the
|
|
|
993 '<' flag is not present in 'cpoptions'.
|
|
|
994 When executing the map command, Vim will replace "<SID>" with the special
|
|
|
995 key code <SNR>, followed by a number that's unique for the script, and an
|
|
|
996 underscore. Example: >
|
|
|
997 :map <SID>Add
|
|
|
998 could define a mapping "<SNR>23_Add".
|
|
|
999
|
|
|
1000 When defining a function in a script, "s:" can be prepended to the name to
|
|
|
1001 make it local to the script. But when a mapping is executed from outside of
|
|
|
1002 the script, it doesn't know in which script the function was defined. To
|
|
|
1003 avoid this problem, use "<SID>" instead of "s:". The same translation is done
|
|
|
1004 as for mappings. This makes it possible to define a call to the function in
|
|
42
|
1005 a mapping.
|
|
7
|
1006
|
|
|
1007 When a local function is executed, it runs in the context of the script it was
|
|
|
1008 defined in. This means that new functions and mappings it defines can also
|
|
|
1009 use "s:" or "<SID>" and it will use the same unique number as when the
|
|
|
1010 function itself was defined. Also, the "s:var" local script variables can be
|
|
|
1011 used.
|
|
|
1012
|
|
|
1013 When executing an autocommand or a user command, it will run in the context of
|
|
|
1014 the script it was defined in. This makes it possible that the command calls a
|
|
|
1015 local function or uses a local mapping.
|
|
|
1016
|
|
|
1017 Otherwise, using "<SID>" outside of a script context is an error.
|
|
|
1018
|
|
|
1019 If you need to get the script number to use in a complicated script, you can
|
|
625
|
1020 use this function: >
|
|
|
1021 function s:SID()
|
|
|
1022 return matchstr(expand('<sfile>'), '<SNR>\zs\d\+\ze_SID$')
|
|
|
1023 endfun
|
|
7
|
1024
|
|
|
1025 The "<SNR>" will be shown when listing functions and mappings. This is useful
|
|
|
1026 to find out what they are defined to.
|
|
|
1027
|
|
|
1028 The |:scriptnames| command can be used to see which scripts have been sourced
|
|
|
1029 and what their <SNR> number is.
|
|
|
1030
|
|
|
1031 This is all {not in Vi} and {not available when compiled without the +eval
|
|
|
1032 feature}.
|
|
|
1033
|
|
|
1034 ==============================================================================
|
|
|
1035 4. User-defined commands *user-commands*
|
|
|
1036
|
|
236
|
1037 It is possible to define your own Ex commands. A user-defined command can act
|
|
7
|
1038 just like a built-in command (it can have a range or arguments, arguments can
|
|
|
1039 be completed as filenames or buffer names, etc), except that when the command
|
|
|
1040 is executed, it is transformed into a normal ex command and then executed.
|
|
|
1041
|
|
|
1042 For starters: See section |40.2| in the user manual.
|
|
|
1043
|
|
|
1044 *E183* *user-cmd-ambiguous*
|
|
|
1045 All user defined commands must start with an uppercase letter, to avoid
|
|
236
|
1046 confusion with builtin commands. (There are a few builtin commands, notably
|
|
7
|
1047 :Next, :Print and :X, which do start with an uppercase letter. The builtin
|
|
|
1048 will always take precedence in these cases). The other characters of the user
|
|
|
1049 command can be uppercase letters, lowercase letters or digits. When using
|
|
|
1050 digits, note that other commands that take a numeric argument may become
|
|
|
1051 ambiguous. For example, the command ":Cc2" could be the user command ":Cc2"
|
|
|
1052 without an argument, or the command ":Cc" with argument "2". It is advised to
|
|
|
1053 put a space between the command name and the argument to avoid these problems.
|
|
|
1054
|
|
236
|
1055 When using a user-defined command, the command can be abbreviated. However, if
|
|
|
1056 an abbreviation is not unique, an error will be issued. Furthermore, a
|
|
7
|
1057 built-in command will always take precedence.
|
|
|
1058
|
|
|
1059 Example: >
|
|
|
1060 :command Rename ...
|
|
|
1061 :command Renumber ...
|
|
|
1062 :Rena " Means "Rename"
|
|
|
1063 :Renu " Means "Renumber"
|
|
|
1064 :Ren " Error - ambiguous
|
|
|
1065 :command Paste ...
|
|
|
1066 :P " The built-in :Print
|
|
|
1067
|
|
|
1068 It is recommended that full names for user-defined commands are used in
|
|
|
1069 scripts.
|
|
|
1070
|
|
|
1071 :com[mand] *:com* *:command*
|
|
236
|
1072 List all user-defined commands. When listing commands,
|
|
7
|
1073 the characters in the first two columns are
|
|
|
1074 ! Command has the -bang attribute
|
|
|
1075 " Command has the -register attribute
|
|
|
1076 b Command is local to current buffer
|
|
|
1077 (see below for details on attributes)
|
|
|
1078
|
|
|
1079 :com[mand] {cmd} List the user-defined commands that start with {cmd}
|
|
|
1080
|
|
482
|
1081 *:command-verbose*
|
|
|
1082 When 'verbose' is non-zero, listing a command will also display where it was
|
|
|
1083 last defined. Example: >
|
|
|
1084
|
|
|
1085 :verbose command TOhtml
|
|
|
1086 Name Args Range Complete Definition
|
|
|
1087 TOhtml 0 % :call Convert2HTML(<line1>, <line2>)
|
|
|
1088 Last set from /usr/share/vim/vim-7.0/plugin/tohtml.vim
|
|
|
1089 <
|
|
483
|
1090 See |:verbose-cmd| for more information.
|
|
482
|
1091
|
|
7
|
1092 *E174* *E182*
|
|
|
1093 :com[mand][!] [{attr}...] {cmd} {rep}
|
|
|
1094 Define a user command. The name of the command is
|
|
236
|
1095 {cmd} and its replacement text is {rep}. The command's
|
|
|
1096 attributes (see below) are {attr}. If the command
|
|
7
|
1097 already exists, an error is reported, unless a ! is
|
|
|
1098 specified, in which case the command is redefined.
|
|
|
1099
|
|
|
1100 :delc[ommand] {cmd} *:delc* *:delcommand* *E184*
|
|
|
1101 Delete the user-defined command {cmd}.
|
|
|
1102
|
|
|
1103 :comc[lear] *:comc* *:comclear*
|
|
|
1104 Delete all user-defined commands.
|
|
|
1105
|
|
|
1106 Command attributes
|
|
|
1107
|
|
236
|
1108 User-defined commands are treated by Vim just like any other ex commands. They
|
|
|
1109 can have arguments, or have a range specified. Arguments are subject to
|
|
|
1110 completion as filenames, buffers, etc. Exactly how this works depends upon the
|
|
7
|
1111 command's attributes, which are specified when the command is defined.
|
|
|
1112
|
|
|
1113 There are a number of attributes, split into four categories: argument
|
|
236
|
1114 handling, completion behavior, range handling, and special cases. The
|
|
7
|
1115 attributes are described below, by category.
|
|
|
1116
|
|
|
1117 Argument handling *E175* *E176*
|
|
|
1118
|
|
|
1119 By default, a user defined command will take no arguments (and an error is
|
|
236
|
1120 reported if any are supplied). However, it is possible to specify that the
|
|
|
1121 command can take arguments, using the -nargs attribute. Valid cases are:
|
|
7
|
1122
|
|
|
1123 -nargs=0 No arguments are allowed (the default)
|
|
|
1124 -nargs=1 Exactly one argument is required
|
|
|
1125 -nargs=* Any number of arguments are allowed (0, 1, or many)
|
|
|
1126 -nargs=? 0 or 1 arguments are allowed
|
|
|
1127 -nargs=+ Arguments must be supplied, but any number are allowed
|
|
|
1128
|
|
|
1129 Arguments are considered to be separated by (unescaped) spaces or Tabs in this
|
|
|
1130 context.
|
|
|
1131
|
|
|
1132 Note that arguments are used as text, not as expressions. Specifically,
|
|
|
1133 "s:var" will use the script-local variable in the script where the command was
|
|
|
1134 defined, not where it is invoked! Example:
|
|
|
1135 script1.vim: >
|
|
|
1136 :let s:error = "None"
|
|
|
1137 :command -nargs=1 Error echoerr <args>
|
|
|
1138 < script2.vim: >
|
|
|
1139 :source script1.vim
|
|
|
1140 :let s:error = "Wrong!"
|
|
|
1141 :Error s:error
|
|
|
1142 Executing script2.vim will result in "None" to be echoed. Not what you
|
|
|
1143 intended! Calling a function may be an alternative.
|
|
|
1144
|
|
|
1145 Completion behavior *:command-completion*
|
|
|
1146 *E179* *E180* *E181*
|
|
|
1147 By default, the arguments of user defined commands do not undergo completion.
|
|
|
1148 However, by specifying one or the other of the following attributes, argument
|
|
|
1149 completion can be enabled:
|
|
|
1150
|
|
|
1151 -complete=augroup autocmd groups
|
|
|
1152 -complete=buffer buffer names
|
|
|
1153 -complete=command Ex command (and arguments)
|
|
|
1154 -complete=dir directory names
|
|
|
1155 -complete=environment environment variable names
|
|
|
1156 -complete=event autocommand events
|
|
|
1157 -complete=expression Vim expression
|
|
|
1158 -complete=file file and directory names
|
|
714
|
1159 -complete=shellcmd Shell command
|
|
7
|
1160 -complete=function function name
|
|
|
1161 -complete=help help subjects
|
|
|
1162 -complete=highlight highlight groups
|
|
|
1163 -complete=mapping mapping name
|
|
|
1164 -complete=menu menus
|
|
|
1165 -complete=option options
|
|
|
1166 -complete=tag tags
|
|
|
1167 -complete=tag_listfiles tags, file names are shown when CTRL-D is hit
|
|
|
1168 -complete=var user variables
|
|
|
1169 -complete=custom,{func} custom completion, defined via {func}
|
|
406
|
1170 -complete=customlist,{func} custom completion, defined via {func}
|
|
7
|
1171
|
|
557
|
1172
|
|
|
1173 Custom completion *:command-completion-custom*
|
|
|
1174 *:command-completion-customlist*
|
|
|
1175 *E467* *E468*
|
|
7
|
1176 It is possible to define customized completion schemes via the "custom,{func}"
|
|
406
|
1177 or the "customlist,{func}" completion argument. The {func} part should be a
|
|
|
1178 function with the following prototype >
|
|
7
|
1179
|
|
|
1180 :function {func}(ArgLead, CmdLine, CursorPos)
|
|
|
1181
|
|
406
|
1182 The function need not use all these arguments. The function should provide the
|
|
|
1183 completion candidates as the return value.
|
|
|
1184
|
|
|
1185 For the "custom" argument, the function should return the completion
|
|
|
1186 candidates one per line in a newline separated string.
|
|
|
1187
|
|
|
1188 For the "customlist" argument, the function should return the completion
|
|
557
|
1189 candidates as a Vim List. Non-string items in the list are ignored.
|
|
406
|
1190
|
|
|
1191 The function arguments are:
|
|
7
|
1192 ArgLead the leading portion of the argument currently being
|
|
|
1193 completed on
|
|
|
1194 CmdLine the entire command line
|
|
557
|
1195 CursorPos the cursor position in it (byte index)
|
|
406
|
1196 The function may use these for determining context. For the "custom"
|
|
|
1197 argument, it is not necessary to filter candidates against the (implicit
|
|
|
1198 pattern in) ArgLead. Vim will do filter the candidates with its regexp engine
|
|
|
1199 after function return, and this is probably more efficient in most cases. For
|
|
|
1200 the "customlist" argument, Vim will not filter the returned completion
|
|
|
1201 candidates and the user supplied function should filter the candidates.
|
|
7
|
1202
|
|
|
1203 The following example lists user names to a Finger command >
|
|
|
1204 :com -complete=custom,ListUsers -nargs=1 Finger !finger <args>
|
|
|
1205 :fun ListUsers(A,L,P)
|
|
|
1206 : return system("cut -d: -f1 /etc/passwd")
|
|
|
1207 :endfun
|
|
|
1208
|
|
406
|
1209 The following example completes filenames from the directories specified in
|
|
|
1210 the 'path' option: >
|
|
|
1211 :com -nargs=1 -bang -complete=customlist,EditFileComplete
|
|
|
1212 \ EditFile edit<bang> <args>
|
|
|
1213 :fun EditFileComplete(A,L,P)
|
|
434
|
1214 : return split(globpath(&path, a:ArgLead), "\n")
|
|
406
|
1215 :endfun
|
|
|
1216 <
|
|

1217
|
|
7
|
1218 Range handling *E177* *E178*
|
|
|
1219
|
|
236
|
1220 By default, user-defined commands do not accept a line number range. However,
|
|
7
|
1221 it is possible to specify that the command does take a range (the -range
|
|
|
1222 attribute), or that it takes an arbitrary count value, either in the line
|
|
|
1223 number position (-range=N, like the |:split| command) or as a "count"
|
|
236
|
1224 argument (-count=N, like the |:Next| command). Possible attributes are:
|
|
7
|
1225
|
|
|
1226 -range Range allowed, default is current line
|
|
|
1227 -range=% Range allowed, default is whole file (1,$)
|
|
|
1228 -range=N A count (default N) which is specified in the line
|
|
|
1229 number position (like |:split|)
|
|
|
1230 -count=N A count (default N) which is specified either in the line
|
|
171
|
1231 number position, or as an initial argument (like |:Next|).
|
|
7
|
1232 Specifying -count (without a default) acts like -count=0
|
|
|
1233
|
|
|
1234 Note that -range=N and -count=N are mutually exclusive - only one should be
|
|
|
1235 specified.
|
|
|
1236
|
|
|
1237 Special cases
|
|
|
1238
|
|
|
1239 There are some special cases as well:
|
|
|
1240
|
|
|
1241 -bang The command can take a ! modifier (like :q or :w)
|
|
|
1242 -bar The command can be followed by a "|" and another command.
|
|
|
1243 A "|" inside the command argument is not allowed then.
|
|
|
1244 Also checks for a " to start a comment.
|
|
|
1245 -register The first argument to the command can be an optional
|
|
|
1246 register name (like :del, :put, :yank).
|
|
|
1247 -buffer The command will only be available in the current buffer.
|
|
|
1248
|
|
|
1249 In the cases of the -count and -register attributes, if the optional argument
|
|
|
1250 is supplied, it is removed from the argument list and is available to the
|
|
|
1251 replacement text separately.
|
|
|
1252
|
|
|
1253 Replacement text
|
|
|
1254
|
|
|
1255 The replacement text for a user defined command is scanned for special escape
|
|
236
|
1256 sequences, using <...> notation. Escape sequences are replaced with values
|
|
|
1257 from the entered command line, and all other text is copied unchanged. The
|
|
788
|
1258 resulting string is executed as an Ex command. To avoid the replacement use
|
|
|
1259 <lt> in plade of the initial <. Thus to include "<bang>" literally use
|
|
|
1260 "<lt>bang>".
|
|
7
|
1261
|
|
|
1262 The valid escape sequences are
|
|
|
1263
|
|
|
1264 *<line1>*
|
|
|
1265 <line1> The starting line of the command range.
|
|
|
1266 *<line2>*
|
|
|
1267 <line2> The final line of the command range.
|
|
|
1268 *<count>*
|
|
|
1269 <count> Any count supplied (as described for the '-range'
|
|
|
1270 and '-count' attributes).
|
|
|
1271 *<bang>*
|
|
|
1272 <bang> (See the '-bang' attribute) Expands to a ! if the
|
|
|
1273 command was executed with a ! modifier, otherwise
|
|
|
1274 expands to nothing.
|
|
|
1275 *<reg>* *<register>*
|
|
|
1276 <reg> (See the '-register' attribute) The optional register,
|
|
236
|
1277 if specified. Otherwise, expands to nothing. <register>
|
|
7
|
1278 is a synonym for this.
|
|
|
1279 *<args>*
|
|
|
1280 <args> The command arguments, exactly as supplied (but as
|
|
|
1281 noted above, any count or register can consume some
|
|
|
1282 of the arguments, which are then not part of <args>).
|
|
|
1283 <lt> A single '<' (Less-Than) character. This is needed if you
|
|
|
1284 want to get a literal copy of one of these escape sequences
|
|
|
1285 into the expansion - for example, to get <bang>, use
|
|
|
1286 <lt>bang>.
|
|
|
1287
|
|
|
1288 *<q-args>*
|
|
|
1289 If the first two characters of an escape sequence are "q-" (for example,
|
|
|
1290 <q-args>) then the value is quoted in such a way as to make it a valid value
|
|
|
1291 for use in an expression. This uses the argument as one single value.
|
|
300
|
1292 When there is no argument <q-args> is an empty string.
|
|
7
|
1293
|
|
|
1294 To allow commands to pass their arguments on to a user-defined function, there
|
|
236
|
1295 is a special form <f-args> ("function args"). This splits the command
|
|
7
|
1296 arguments at spaces and Tabs, quotes each argument individually, and the
|
|
|
1297 <f-args> sequence is replaced by the comma-separated list of quoted arguments.
|
|
482
|
1298 See the Mycmd example below. If no arguments are given <f-args> is removed.

1336
|
|
|
1337 The command Allargs takes any Vim command(s) as argument and executes it on all
|
|
|
1338 files in the argument list. Usage example (note use of the "e" flag to ignore
|
|
|
1339 errors and the "update" command to write modified buffers): >
|
|
|
1340 :Allargs %s/foo/bar/ge|update
|
|
|
1341 This will invoke: >
|
|
|
1342 :call Allargs("%s/foo/bar/ge|update")
|

|
1343 <
|
|
|
1344 When defining an user command in a script, it will be able to call functions
|
|
|
1345 local to the script and use mappings local to the script. When the user
|
|
|
1346 invokes the user command, it will run in the context of the script it was
|
|
|
1347 defined in. This matters if |<SID>| is used in a command.
