15Vim has a number of internal variables and switches which can be set to
16achieve special effects. These options come in three forms:
17 boolean can only be on or off *boolean* *toggle*
18 number has a numeric value
19 string has a string value

24 *:se* *:set*
Bram Moolenaar6b915c02020-01-18 15:53:19 +010025:se[t][!] Show all options that differ from their default value.
26 When [!] is present every option is on a separate
27 line.
Bram Moolenaar071d4272004-06-13 20:20:40 +000028
Bram Moolenaar6b915c02020-01-18 15:53:19 +010029:se[t][!] all Show all but terminal options.
30 When [!] is present every option is on a separate
31 line.
Bram Moolenaar071d4272004-06-13 20:20:40 +000032
33:se[t] termcap Show all terminal options. Note that in the GUI the
34 key codes are not shown, because they are generated
35 internally and can't be changed. Changing the terminal
36 codes in the GUI is not useful either...
Bram Moolenaarf1dcd142022-12-31 15:30:45 +000037 The options have the form t_AB, see
38 |terminal-options|.

h_east59858792023-10-25 22:47:05 +090074 *:set-args* *:set=* *E487* *E521*
Bram Moolenaar071d4272004-06-13 20:20:40 +000075:se[t] {option}={value} or
76:se[t] {option}:{value}
77 Set string or number option to {value}.
78 For numeric options the value can be given in decimal,
Bram Moolenaar3848e002016-03-19 18:42:29 +010079 hex (preceded with 0x) or octal (preceded with '0').
Bram Moolenaar071d4272004-06-13 20:20:40 +000080 The old value can be inserted by typing 'wildchar' (by
81 default this is a <Tab> or CTRL-E if 'compatible' is
Yee Cheng Chin900894b2023-09-29 20:42:32 +020082 set). Many string options with fixed syntax and names
83 also support completing known values. See
84 |cmdline-completion| and |complete-set-option|.
Bram Moolenaar071d4272004-06-13 20:20:40 +000085 White space between {option} and '=' is allowed and
86 will be ignored. White space between '=' and {value}
87 is not allowed.
88 See |option-backslash| for using white space and
89 backslashes in {value}.
90
91:se[t] {option}+={value} *:set+=*
92 Add the {value} to a number option, or append the
93 {value} to a string option. When the option is a
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +010094 comma-separated list, a comma is added, unless the
Bram Moolenaar071d4272004-06-13 20:20:40 +000095 value was empty.
96 If the option is a list of flags, superfluous flags
Bram Moolenaara5792f52005-11-23 21:25:05 +000097 are removed. When adding a flag that was already
98 present the option value doesn't change.
Bram Moolenaar899dddf2006-03-26 21:06:50 +000099 Also see |:set-args| above.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000100
101:se[t] {option}^={value} *:set^=*
102 Multiply the {value} to a number option, or prepend
103 the {value} to a string option. When the option is a
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +0100104 comma-separated list, a comma is added, unless the
Bram Moolenaar071d4272004-06-13 20:20:40 +0000105 value was empty.
106 Also see |:set-args| above.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000107
108:se[t] {option}-={value} *:set-=*
109 Subtract the {value} from a number option, or remove
110 the {value} from a string option, if it is there.
111 If the {value} is not found in a string option, there
112 is no error or warning. When the option is a comma
113 separated list, a comma is deleted, unless the option
114 becomes empty.
115 When the option is a list of flags, {value} must be
116 exactly as they appear in the option. Remove flags
117 one by one to avoid problems.
Yee Cheng Chin900894b2023-09-29 20:42:32 +0200118 The individual values from a comma separated list or
119 list of flags can be inserted by typing 'wildchar'.
120 See |complete-set-option|.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000121 Also see |:set-args| above.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000122
123The {option} arguments to ":set" may be repeated. For example: >
124 :set ai nosi sw=3 ts=3
125If you make an error in one of the arguments, an error message will be given
126and the following arguments will be ignored.
127
128 *:set-verbose*
129When 'verbose' is non-zero, displaying an option value will also tell where it
130was last set. Example: >
131 :verbose set shiftwidth cindent?
Bram Moolenaar95bafa22018-10-02 13:26:25 +0200132< shiftwidth=4 ~
133 Last set from modeline line 1 ~
134 cindent ~
135 Last set from /usr/local/share/vim/vim60/ftplugin/c.vim line 30 ~
Bram Moolenaar446cb832008-06-24 21:56:24 +0000136This is only done when specific option values are requested, not for ":verbose
137set all" or ":verbose set" without an argument.
138When the option was set by hand there is no "Last set" message.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000139When the option was set while executing a function, user command or
140autocommand, the script in which it was defined is reported.
141Note that an option may also have been set as a side effect of setting
142'compatible'.
Bram Moolenaar446cb832008-06-24 21:56:24 +0000143A few special texts:
Bram Moolenaar95bafa22018-10-02 13:26:25 +0200144 Last set from modeline line 1 ~
Bram Moolenaar446cb832008-06-24 21:56:24 +0000145 Option was set in a |modeline|.
146 Last set from --cmd argument ~
147 Option was set with command line argument |--cmd| or +.
148 Last set from -c argument ~
149 Option was set with command line argument |-c|, +, |-S| or
150 |-q|.
151 Last set from environment variable ~
152 Option was set from an environment variable, $VIMINIT,
153 $GVIMINIT or $EXINIT.
154 Last set from error handler ~
155 Option was cleared when evaluating it resulted in an error.

Bram Moolenaar071d4272004-06-13 20:20:40 +0000158
159 *:set-termcap* *E522*
Bram Moolenaar1d2ba7f2006-02-14 22:29:30 +0000160For {option} the form "t_xx" may be used to set a terminal option. This will
Bram Moolenaar071d4272004-06-13 20:20:40 +0000161override the value from the termcap. You can then use it in a mapping. If
162the "xx" part contains special characters, use the <t_xx> form: >
163 :set <t_#4>=^[Ot
164This can also be used to translate a special code for a normal key. For
165example, if Alt-b produces <Esc>b, use this: >
166 :set <M-b>=^[b
167(the ^[ is a real <Esc> here, use CTRL-V <Esc> to enter it)
168The advantage over a mapping is that it works in all situations.
169
Bram Moolenaar0b2f94d2011-03-22 14:35:05 +0100170You can define any key codes, e.g.: >
171 :set t_xy=^[foo;
172There is no warning for using a name that isn't recognized. You can map these
173codes as you like: >
174 :map <t_xy> something
175< *E846*
176When a key code is not set, it's like it does not exist. Trying to get its
177value will result in an error: >
178 :set t_kb=
179 :set t_kb
Bram Moolenaar6f4754b2022-01-23 12:07:04 +0000180< E846: Key code not set: t_kb ~
Bram Moolenaar0b2f94d2011-03-22 14:35:05 +0100181
Bram Moolenaar293ee4d2004-12-09 21:34:53 +0000182The t_xx options cannot be set from a |modeline| or in the |sandbox|, for
183security reasons.
184
Bram Moolenaar071d4272004-06-13 20:20:40 +0000185The listing from ":set" looks different from Vi. Long string options are put
Bram Moolenaarf4b8e572004-06-24 15:53:16 +0000186at the end of the list. The number of options is quite large. The output of
Bram Moolenaar071d4272004-06-13 20:20:40 +0000187"set all" probably does not fit on the screen, causing Vim to give the
188|more-prompt|.
189
190 *option-backslash*
191To include white space in a string option value it has to be preceded with a
192backslash. To include a backslash you have to use two. Effectively this
193means that the number of backslashes in an option value is halved (rounded
194down).
Yee Cheng Chin54844852023-10-09 18:12:31 +0200195In options 'path', 'cdpath', and 'tags', spaces have to be preceded with three
196backslashes instead for compatibility with version 3.0 where the options can
197be separated by either commas or spaces.
198Comma-separated options like 'backupdir' and 'tags' will also require commas
199to be escaped with two backslashes, whereas this is not needed for
200non-comma-separated ones like 'makeprg'.
201When setting options using |:let| and |literal-string|, you need to use one
202fewer layer of backslash.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000203A few examples: >
Yee Cheng Chin54844852023-10-09 18:12:31 +0200204 :set makeprg=make\ file results in "make file"
205 :let &makeprg='make file' (same as above)
206 :set makeprg=make\\\ file results in "make\ file"
207 :set tags=tags\ /usr/tags results in "tags" and "/usr/tags"
208 :set tags=tags\\\ file results in "tags file"
209 :let &tags='tags\ file' (same as above)
210
211 :set makeprg=make,file results in "make,file"
212 :set makeprg=make\\,file results in "make\,file"
213 :set tags=tags,file results in "tags" and "file"
214 :set tags=tags\\,file results in "tags,file"
215 :let &tags='tags\,file' (same as above)
Bram Moolenaar071d4272004-06-13 20:20:40 +0000216
Bram Moolenaarf4b8e572004-06-24 15:53:16 +0000217The "|" character separates a ":set" command from a following command. To
218include the "|" in the option value, use "\|" instead. This example sets the
Bram Moolenaar071d4272004-06-13 20:20:40 +0000219'titlestring' option to "hi|there": >
220 :set titlestring=hi\|there
221This sets the 'titlestring' option to "hi" and 'iconstring' to "there": >
222 :set titlestring=hi|set iconstring=there
223
Bram Moolenaar89a9c152021-08-29 21:55:35 +0200224Similarly, in legacy script the double quote character starts a comment. To
225include the '"' in the option value, use '\"' instead. This example sets the
226'titlestring' option to 'hi "there"': >
Bram Moolenaar7df351e2006-01-23 22:30:28 +0000227 :set titlestring=hi\ \"there\"
228
Bram Moolenaar89a9c152021-08-29 21:55:35 +0200229In |Vim9| script it's simpler, comments start with a '#' character, and only
230when preceded by white space. A backslash is needed less often: >
231 vim9script
232 set titlestring=hi\ "there"
233 set titlestring=hi#there#
234 set titlestring=hi\ \#there#
235
Bram Moolenaar5666fcd2019-12-26 14:35:26 +0100236For Win32 backslashes in file names are mostly not removed. More precise: For
237options that expect a file name (those where environment variables are
238expanded) a backslash before a normal file name character is not removed. But
239a backslash before a special character (space, backslash, comma, etc.) is used
240like explained above.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000241There is one special situation, when the value starts with "\\": >
242 :set dir=\\machine\path results in "\\machine\path"
243 :set dir=\\\\machine\\path results in "\\machine\path"
244 :set dir=\\path\\file results in "\\path\file" (wrong!)
245For the first one the start is kept, but for the second one the backslashes
246are halved. This makes sure it works both when you expect backslashes to be
Bram Moolenaarf4b8e572004-06-24 15:53:16 +0000247halved and when you expect the backslashes to be kept. The third gives a
Bram Moolenaar071d4272004-06-13 20:20:40 +0000248result which is probably not what you want. Avoid it.
249
250 *add-option-flags* *remove-option-flags*
251 *E539* *E550* *E551* *E552*
252Some options are a list of flags. When you want to add a flag to such an
253option, without changing the existing ones, you can do it like this: >
254 :set guioptions+=a
255Remove a flag from an option like this: >
256 :set guioptions-=a
257This removes the 'a' flag from 'guioptions'.
Bram Moolenaarf4b8e572004-06-24 15:53:16 +0000258Note that you should add or remove one flag at a time. If 'guioptions' has
Bram Moolenaar071d4272004-06-13 20:20:40 +0000259the value "ab", using "set guioptions-=ba" won't work, because the string "ba"
260doesn't appear.
261
262 *:set_env* *expand-env* *expand-environment-var*
Bram Moolenaard4755bb2004-09-02 19:12:26 +0000263Environment variables in specific string options will be expanded. If the
Bram Moolenaar071d4272004-06-13 20:20:40 +0000264environment variable exists the '$' and the following environment variable
265name is replaced with its value. If it does not exist the '$' and the name
266are not modified. Any non-id character (not a letter, digit or '_') may
267follow the environment variable name. That character and what follows is
268appended to the value of the environment variable. Examples: >
269 :set term=$TERM.new
270 :set path=/usr/$INCLUDE,$HOME/include,.
271When adding or removing a string from an option with ":set opt-=val" or ":set
272opt+=val" the expansion is done before the adding or removing.
273
274
275Handling of local options *local-options*
276
Christian Brabandt4a8eb6e2023-08-13 19:43:42 +0200277Note: The following also applies to |global-local| options.
278
Bram Moolenaar071d4272004-06-13 20:20:40 +0000279Some of the options only apply to a window or buffer. Each window or buffer
Bram Moolenaar51628222016-12-01 23:03:28 +0100280has its own copy of this option, thus each can have its own value. This
Bram Moolenaar071d4272004-06-13 20:20:40 +0000281allows you to set 'list' in one window but not in another. And set
282'shiftwidth' to 3 in one buffer and 4 in another.
283
284The following explains what happens to these local options in specific
285situations. You don't really need to know all of this, since Vim mostly uses
286the option values you would expect. Unfortunately, doing what the user
287expects is a bit complicated...
288
289When splitting a window, the local options are copied to the new window. Thus
290right after the split the contents of the two windows look the same.
291
292When editing a new buffer, its local option values must be initialized. Since
293the local options of the current buffer might be specifically for that buffer,
294these are not used. Instead, for each buffer-local option there also is a
295global value, which is used for new buffers. With ":set" both the local and
296global value is changed. With "setlocal" only the local value is changed,
297thus this value is not used when editing a new buffer.
298
Bram Moolenaar95ec9d62016-08-12 18:29:59 +0200299When editing a buffer that has been edited before, the options from the window
300that was last closed are used again. If this buffer has been edited in this
301window, the values from back then are used. Otherwise the values from the
302last closed window where the buffer was edited last are used.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000303
304It's possible to set a local window option specifically for a type of buffer.
305When you edit another buffer in the same window, you don't want to keep
306using these local window options. Therefore Vim keeps a global value of the
307local window options, which is used when editing another buffer. Each window
308has its own copy of these values. Thus these are local to the window, but
309global to all buffers in the window. With this you can do: >
310 :e one
311 :set list
312 :e two
313Now the 'list' option will also be set in "two", since with the ":set list"
314command you have also set the global value. >
315 :set nolist
316 :e one
317 :setlocal list
318 :e two
319Now the 'list' option is not set, because ":set nolist" resets the global
320value, ":setlocal list" only changes the local value and ":e two" gets the
321global value. Note that if you do this next: >
322 :e one
Bram Moolenaar531da592013-05-06 05:58:55 +0200323You will get back the 'list' value as it was the last time you edited "one".
324The options local to a window are remembered for each buffer. This also
325happens when the buffer is not loaded, but they are lost when the buffer is
326wiped out |:bwipe|.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000327
Christian Brabandt596ad662023-08-16 00:11:09 +0200328Special local window options *local-noglobal*
Christian Brabandt4a8eb6e2023-08-13 19:43:42 +0200329
330The following local window options won't be copied over when new windows are
331created, thus they behave slightly differently:
332

356 value the global value is set.

363 the global value is being used, "--" is displayed
364 before the option name.
365 For a global option the global value is

388 :set option? - display
389 :setlocal option? - display
390:setglobal option? display -
391
392
393Global options with a local value *global-local*
394
Bram Moolenaarb5bf5b82004-12-24 14:35:23 +0000395Options are global when you mostly use one value for all buffers and windows.
396For some global options it's useful to sometimes have a different local value.
397You can set the local value with ":setlocal". That buffer or window will then
398use the local value, while other buffers and windows continue using the global
399value.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000400
401For example, you have two windows, both on C source code. They use the global
402'makeprg' option. If you do this in one of the two windows: >
403 :set makeprg=gmake
404then the other window will switch to the same value. There is no need to set
405the 'makeprg' option in the other C source window too.
406However, if you start editing a Perl file in a new window, you want to use
Bram Moolenaar02467872007-05-06 13:22:01 +0000407another 'makeprg' for it, without changing the value used for the C source
Bram Moolenaarf4b8e572004-06-24 15:53:16 +0000408files. You use this command: >
Bram Moolenaar071d4272004-06-13 20:20:40 +0000409 :setlocal makeprg=perlmake
410You can switch back to using the global value by making the local value empty: >
411 :setlocal makeprg=
Bram Moolenaar314dd792019-02-03 15:27:20 +0100412This only works for a string option. For a number or boolean option you need
413to use the "<" flag, like this: >
Bram Moolenaar071d4272004-06-13 20:20:40 +0000414 :setlocal autoread<
Bram Moolenaar314dd792019-02-03 15:27:20 +0100415Note that for non-boolean and non-number options using "<" copies the global
416value to the local value, it doesn't switch back to using the global value
417(that matters when the global value changes later). You can also use: >
Bram Moolenaar899dddf2006-03-26 21:06:50 +0000418 :set path<
419This will make the local value of 'path' empty, so that the global value is
420used. Thus it does the same as: >
421 :setlocal path=
Bram Moolenaar2f0936c2022-01-08 21:51:59 +0000422Note: In the future more global options can be made |global-local|. Using
Bram Moolenaar071d4272004-06-13 20:20:40 +0000423":setlocal" on a global option might work differently then.
424
Yegappan Lakshmanan777175b2021-11-18 22:08:57 +0000425 *option-value-function*
426Some options ('completefunc', 'imactivatefunc', 'imstatusfunc', 'omnifunc',
Yegappan Lakshmanan8658c752021-12-03 11:09:29 +0000427'operatorfunc', 'quickfixtextfunc', 'tagfunc' and 'thesaurusfunc') are set to
Yegappan Lakshmanan64095532021-12-06 11:03:55 +0000428a function name or a function reference or a lambda function. When using a
429lambda it will be converted to the name, e.g. "<lambda>123". Examples:
Yegappan Lakshmanan777175b2021-11-18 22:08:57 +0000430>
431 set opfunc=MyOpFunc
Yegappan Lakshmanan19916a82021-11-24 16:32:55 +0000432 set opfunc=function('MyOpFunc')
433 set opfunc=funcref('MyOpFunc')
Yegappan Lakshmanan05e59e32021-12-01 10:30:07 +0000434 set opfunc={a\ ->\ MyOpFunc(a)}
Bram Moolenaar1fca5f32022-02-18 17:50:47 +0000435
436Set to a script-local function: >
437 set opfunc=s:MyLocalFunc
438 set opfunc=<SID>MyLocalFunc
439In |Vim9| script the "s:" and "<SID>" can be omitted if the function exists in
440the script: >
441 set opfunc=MyLocalFunc
442
443Set using a funcref variable: >
Yegappan Lakshmanan05e59e32021-12-01 10:30:07 +0000444 let Fn = function('MyTagFunc')

Bram Moolenaar1fca5f32022-02-18 17:50:47 +0000449
450Set using a variable with lambda expression: >
Yegappan Lakshmanan05e59e32021-12-01 10:30:07 +0000451 let L = {a, b, c -> MyTagFunc(a, b , c)}
Yegappan Lakshmanan64095532021-12-06 11:03:55 +0000452 let &tagfunc = L
Bram Moolenaar7b1463b2021-12-11 17:24:39 +0000453
454In Vim9 script, in a compiled function, you can use a lambda, but a
Aliaksei Budaveib043ff32023-10-03 17:39:53 +0300455closure does not work, because the function will be called without the
Bram Moolenaar7b1463b2021-12-11 17:24:39 +0000456context of where it was defined.

463 not done yet in a sequence of (nested) autocommands.
464 This is short for: >
465 :if !did_filetype()
466 : setlocal filetype={filetype}
467 :endif
468< This command is used in a filetype.vim file to avoid
469 setting the 'filetype' option twice, causing different
470 settings and syntax files to be loaded.
Bram Moolenaar6aa8cea2017-06-05 14:44:35 +0200471
472 When the optional FALLBACK argument is present, a
473 later :setfiletype command will override the
Bram Moolenaar26967612019-03-17 17:13:16 +0100474 'filetype'. This is to be used for filetype
475 detections that are just a guess. |did_filetype()|

485 Modify the value of the option and hit <CR> on the
486 "set" line to set the new value. For window and
487 buffer specific options, the last accessed window is
488 used to set the option value in, unless this is a help
489 window, in which case the window below help window is
490 used (skipping the option-window).

492 feature}
Bram Moolenaar071d4272004-06-13 20:20:40 +0000493
494 *$HOME*
495Using "~" is like using "$HOME", but it is only recognized at the start of an
496option and after a space or comma.
497
498On Unix systems "~user" can be used too. It is replaced by the home directory
499of user "user". Example: >
500 :set path=~mool/include,/usr/include,.
501
502On Unix systems the form "${HOME}" can be used too. The name between {} can
503contain non-id characters then. Note that if you want to use this for the
504"gf" command, you need to add the '{' and '}' characters to 'isfname'.
505
506NOTE: expanding environment variables and "~/" is only done with the ":set"
507command, not when assigning a value to an option with ":let".
508
Bram Moolenaarc572da52017-08-27 16:52:01 +0200509 *$HOME-windows*
510On MS-Windows, if $HOME is not defined as an environment variable, then
511at runtime Vim will set it to the expansion of $HOMEDRIVE$HOMEPATH.
Bram Moolenaar37c64c72017-09-19 22:06:03 +0200512If $HOMEDRIVE is not set then $USERPROFILE is used.
513
514This expanded value is not exported to the environment, this matters when
515running an external command: >
516 :echo system('set | findstr ^HOME=')
517and >
518 :echo luaeval('os.getenv("HOME")')
519should echo nothing (an empty string) despite exists('$HOME') being true.
520When setting $HOME to a non-empty string it will be exported to the
521subprocesses.
Bram Moolenaarc572da52017-08-27 16:52:01 +0200522
Bram Moolenaar071d4272004-06-13 20:20:40 +0000523
524Note the maximum length of an expanded option is limited. How much depends on
525the system, mostly it is something like 256 or 1024 characters.
526
527 *:fix* *:fixdel*
528:fix[del] Set the value of 't_kD':
529 't_kb' is 't_kD' becomes ~
530 CTRL-? CTRL-H
531 not CTRL-? CTRL-?
532
Bram Moolenaar82be4842021-01-11 19:40:15 +0100533 (CTRL-? is 0o177 octal, 0x7f hex)
Bram Moolenaar071d4272004-06-13 20:20:40 +0000534
535 If your delete key terminal code is wrong, but the
536 code for backspace is alright, you can put this in
537 your .vimrc: >
538 :fixdel
539< This works no matter what the actual code for
540 backspace is.
541
542 If the backspace key terminal code is wrong you can
543 use this: >
544 :if &term == "termname"
545 : set t_kb=^V<BS>
546 : fixdel
547 :endif
548< Where "^V" is CTRL-V and "<BS>" is the backspace key
Bram Moolenaarf4b8e572004-06-24 15:53:16 +0000549 (don't type four characters!). Replace "termname"
Bram Moolenaar071d4272004-06-13 20:20:40 +0000550 with your terminal name.
551
552 If your <Delete> key sends a strange key sequence (not
553 CTRL-? or CTRL-H) you cannot use ":fixdel". Then use: >
554 :if &term == "termname"
555 : set t_kD=^V<Delete>
556 :endif
557< Where "^V" is CTRL-V and "<Delete>" is the delete key
558 (don't type eight characters!). Replace "termname"
559 with your terminal name.
560
561 *Linux-backspace*
562 Note about Linux: By default the backspace key
563 produces CTRL-?, which is wrong. You can fix it by
564 putting this line in your rc.local: >
565 echo "keycode 14 = BackSpace" | loadkeys
566<
567 *NetBSD-backspace*
568 Note about NetBSD: If your backspace doesn't produce
569 the right code, try this: >
570 xmodmap -e "keycode 22 = BackSpace"
571< If this works, add this in your .Xmodmap file: >
572 keysym 22 = BackSpace
573< You need to restart for this to take effect.
574
575==============================================================================
5762. Automatically setting options *auto-setting*
577
578Besides changing options with the ":set" command, there are three alternatives
579to set options automatically for one or more files:
580
5811. When starting Vim initializations are read from various places. See
582 |initialization|. Most of them are performed for all editing sessions,
583 and some of them depend on the directory where Vim is started.
584 You can create an initialization file with |:mkvimrc|, |:mkview| and
585 |:mksession|.
5862. If you start editing a new file, the automatic commands are executed.
587 This can be used to set options for files matching a particular pattern and
588 many other things. See |autocommand|.
5893. If you start editing a new file, and the 'modeline' option is on, a
590 number of lines at the beginning and end of the file are checked for
591 modelines. This is explained here.
592
593 *modeline* *vim:* *vi:* *ex:* *E520*
594There are two forms of modelines. The first form:
Bram Moolenaar664f3cf2019-12-07 16:03:51 +0100595 [text{white}]{vi:|vim:|ex:}[white]{options}
Bram Moolenaar071d4272004-06-13 20:20:40 +0000596
Bram Moolenaar664f3cf2019-12-07 16:03:51 +0100597[text{white}] empty or any text followed by at least one blank
598 character (<Space> or <Tab>); "ex:" always requires at
599 least one blank character
Bram Moolenaar14b69452013-06-29 23:05:20 +0200600{vi:|vim:|ex:} the string "vi:", "vim:" or "ex:"
Bram Moolenaar22dbc772013-06-28 18:44:48 +0200601[white] optional white space
602{options} a list of option settings, separated with white space
603 or ':', where each part between ':' is the argument
604 for a ":set" command (can be empty)
Bram Moolenaar071d4272004-06-13 20:20:40 +0000605
Bram Moolenaar14b69452013-06-29 23:05:20 +0200606Examples:
Bram Moolenaar97b2ad32006-03-18 21:40:56 +0000607 vi:noai:sw=3 ts=6 ~
Bram Moolenaar14b69452013-06-29 23:05:20 +0200608 vim: tw=77 ~
Bram Moolenaar071d4272004-06-13 20:20:40 +0000609
610The second form (this is compatible with some versions of Vi):
611
Bram Moolenaarade0d392020-01-21 22:33:58 +0100612 [text{white}]{vi:|vim:|Vim:|ex:}[white]se[t] {options}:[text]
Bram Moolenaar071d4272004-06-13 20:20:40 +0000613
Bram Moolenaarade0d392020-01-21 22:33:58 +0100614[text{white}] empty or any text followed by at least one blank
615 character (<Space> or <Tab>); "ex:" always requires at
616 least one blank character
Bram Moolenaar22dbc772013-06-28 18:44:48 +0200617{vi:|vim:|Vim:|ex:} the string "vi:", "vim:", "Vim:" or "ex:"
618[white] optional white space
Bram Moolenaar14b69452013-06-29 23:05:20 +0200619se[t] the string "set " or "se " (note the space); When
620 "Vim" is used it must be "set".
Bram Moolenaar22dbc772013-06-28 18:44:48 +0200621{options} a list of options, separated with white space, which
622 is the argument for a ":set" command
623: a colon
624[text] any text or empty
Bram Moolenaar071d4272004-06-13 20:20:40 +0000625
Bram Moolenaar14b69452013-06-29 23:05:20 +0200626Examples:
Bram Moolenaar97b2ad32006-03-18 21:40:56 +0000627 /* vim: set ai tw=75: */ ~
Bram Moolenaar14b69452013-06-29 23:05:20 +0200628 /* Vim: set ai tw=75: */ ~
Bram Moolenaar071d4272004-06-13 20:20:40 +0000629
Bram Moolenaar22dbc772013-06-28 18:44:48 +0200630The white space before {vi:|vim:|Vim:|ex:} is required. This minimizes the
631chance that a normal word like "lex:" is caught. There is one exception:
632"vi:" and "vim:" can also be at the start of the line (for compatibility with
633version 3.0). Using "ex:" at the start of the line will be ignored (this
634could be short for "example:").
Bram Moolenaar071d4272004-06-13 20:20:40 +0000635
Hu Jialun9dcd3492021-08-28 20:42:50 +0200636If the modeline is disabled within a modeline, subsequent modelines will be
637ignored. This is to allow turning off modeline on a per-file basis. This is
638useful when a line looks like a modeline but isn't. For example, it would be
639good to start a YAML file containing strings like "vim:" with
640 # vim: nomodeline ~
641so as to avoid modeline misdetection. Following options on the same line
642after modeline deactivation, if any, are still evaluated (but you would
643normally not have any).
644
Bram Moolenaar071d4272004-06-13 20:20:40 +0000645 *modeline-local*
646The options are set like with ":setlocal": The new value only applies to the
Bram Moolenaar843ee412004-06-30 16:16:41 +0000647buffer and window that contain the file. Although it's possible to set global
648options from a modeline, this is unusual. If you have two windows open and
649the files in it set the same global option to a different value, the result
650depends on which one was opened last.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000651
Bram Moolenaar15d0a8c2004-09-06 17:44:46 +0000652When editing a file that was already loaded, only the window-local options
653from the modeline are used. Thus if you manually changed a buffer-local
654option after opening the file, it won't be changed if you edit the same buffer
655in another window. But window-local options will be set.

Bram Moolenaar071d4272004-06-13 20:20:40 +0000657 *modeline-version*
658If the modeline is only to be used for some versions of Vim, the version
Bram Moolenaar22dbc772013-06-28 18:44:48 +0200659number can be specified where "vim:" or "Vim:" is used:
Bram Moolenaar071d4272004-06-13 20:20:40 +0000660 vim{vers}: version {vers} or later
661 vim<{vers}: version before {vers}
662 vim={vers}: version {vers}
663 vim>{vers}: version after {vers}
Bram Moolenaar2b8388b2015-02-28 13:11:45 +0100664{vers} is 700 for Vim 7.0 (hundred times the major version plus minor).
665For example, to use a modeline only for Vim 7.0:
666 /* vim700: set foldmethod=marker */ ~
667To use a modeline for Vim after version 7.2:
668 /* vim>702: set cole=2: */ ~
Bram Moolenaar071d4272004-06-13 20:20:40 +0000669There can be no blanks between "vim" and the ":".
670
671
672The number of lines that are checked can be set with the 'modelines' option.
673If 'modeline' is off or 'modelines' is 0 no lines are checked.
674
675Note that for the first form all of the rest of the line is used, thus a line
Bram Moolenaar97b2ad32006-03-18 21:40:56 +0000676like:
677 /* vi:ts=4: */ ~
678will give an error message for the trailing "*/". This line is OK:
679 /* vi:set ts=4: */ ~
Bram Moolenaar071d4272004-06-13 20:20:40 +0000680
681If an error is detected the rest of the line is skipped.
682
683If you want to include a ':' in a set command precede it with a '\'. The
Bram Moolenaar97b2ad32006-03-18 21:40:56 +0000684backslash in front of the ':' will be removed. Example:
Bram Moolenaar95a9dd12019-12-19 22:12:03 +0100685 /* vi:set fillchars=stl\:^,vert\:\|: */ ~
686This sets the 'fillchars' option to "stl:^,vert:\|". Only a single backslash
687before the ':' is removed. Thus to include "\:" you have to specify "\\:".
Bram Moolenaar110289e2019-05-23 15:38:06 +0200688 *E992*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000689No other commands than "set" are supported, for security reasons (somebody
Bram Moolenaar8243a792007-05-01 17:05:03 +0000690might create a Trojan horse text file with modelines). And not all options
Bram Moolenaar110289e2019-05-23 15:38:06 +0200691can be set. For some options a flag is set, so that when the value is used
692the |sandbox| is effective. Some options can only be set from the modeline
693when 'modelineexpr' is set (the default is off).
694
695Still, there is always a small risk that a modeline causes trouble. E.g.,
696when some joker sets 'textwidth' to 5 all your lines are wrapped unexpectedly.
697So disable modelines before editing untrusted text. The mail ftplugin does
698this, for example.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000699
700Hint: If you would like to do something else than setting an option, you could
701define an autocommand that checks the file for a specific string. For
702example: >
703 au BufReadPost * if getline(1) =~ "VAR" | call SetVar() | endif
704And define a function SetVar() that does something with the line containing
705"VAR".
706
707==============================================================================
7083. Options summary *option-summary*
709
710In the list below all the options are mentioned with their full name and with
711an abbreviation if there is one. Both forms may be used.
712
713In this document when a boolean option is "set" that means that ":set option"
714is entered. When an option is "reset", ":set nooption" is used.
715
716For some options there are two default values: The "Vim default", which is
717used when 'compatible' is not set, and the "Vi default", which is used when
718'compatible' is set.
719
720Most options are the same in all windows and buffers. There are a few that
Bram Moolenaarf4b8e572004-06-24 15:53:16 +0000721are specific to how the text is presented in a window. These can be set to a
Bram Moolenaar071d4272004-06-13 20:20:40 +0000722different value in each window. For example the 'list' option can be set in
723one window and reset in another for the same text, giving both types of view
724at the same time. There are a few options that are specific to a certain
725file. These can have a different value for each file or buffer. For example
726the 'textwidth' option can be 78 for a normal text file and 0 for a C
727program.
728
729 global one option for all buffers and windows
730 local to window each window has its own copy of this option
731 local to buffer each buffer has its own copy of this option
732
733When creating a new window the option values from the currently active window
734are used as a default value for the window-specific options. For the
735buffer-specific options this depends on the 's' and 'S' flags in the
736'cpoptions' option. If 's' is included (which is the default) the values for
737buffer options are copied from the currently active buffer when a buffer is
Bram Moolenaarf4b8e572004-06-24 15:53:16 +0000738first entered. If 'S' is present the options are copied each time the buffer
739is entered, this is almost like having global options. If 's' and 'S' are not
Bram Moolenaar071d4272004-06-13 20:20:40 +0000740present, the options are copied from the currently active buffer when the
741buffer is created.

Bram Moolenaar578b49e2005-09-10 19:22:57 +0000743Hidden options *hidden-options*
Bram Moolenaar071d4272004-06-13 20:20:40 +0000744
Bram Moolenaar578b49e2005-09-10 19:22:57 +0000745Not all options are supported in all versions. This depends on the supported
746features and sometimes on the system. A remark about this is in curly braces
747below. When an option is not supported it may still be set without getting an
748error, this is called a hidden option. You can't get the value of a hidden
749option though, it is not stored.
750
751To test if option "foo" can be used with ":set" use something like this: >
752 if exists('&foo')
753This also returns true for a hidden option. To test if option "foo" is really
754supported use something like this: >
755 if exists('+foo')

795 Tells Vim what to do with characters with East Asian Width Class
796 Ambiguous (such as Euro, Registered Sign, Copyright Sign, Greek
797 letters, Cyrillic letters).
798
799 There are currently two possible values:
Bram Moolenaar582fd852005-03-28 20:58:01 +0000800 "single": Use the same width as characters in US-ASCII. This is
Bram Moolenaar071d4272004-06-13 20:20:40 +0000801 expected by most users.
802 "double": Use twice the width of ASCII characters.
Bram Moolenaar5c3bd0a2010-08-04 20:55:44 +0200803 *E834* *E835*
804 The value "double" cannot be used if 'listchars' or 'fillchars'
Bram Moolenaar079ba762021-10-23 12:08:41 +0100805 contains a character that would be double width. These errors may
806 also be given when calling setcellwidths().
Bram Moolenaar08aac3c2020-08-28 21:04:24 +0200807
808 The values are overruled for characters specified with
809 |setcellwidths()|.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000810
811 There are a number of CJK fonts for which the width of glyphs for
812 those characters are solely based on how many octets they take in
813 legacy/traditional CJK encodings. In those encodings, Euro,
814 Registered sign, Greek/Cyrillic letters are represented by two octets,
Bram Moolenaar582fd852005-03-28 20:58:01 +0000815 therefore those fonts have "wide" glyphs for them. This is also
Bram Moolenaar071d4272004-06-13 20:20:40 +0000816 true of some line drawing characters used to make tables in text
Bram Moolenaar582fd852005-03-28 20:58:01 +0000817 file. Therefore, when a CJK font is used for GUI Vim or
Bram Moolenaar071d4272004-06-13 20:20:40 +0000818 Vim is running inside a terminal (emulators) that uses a CJK font
819 (or Vim is run inside an xterm invoked with "-cjkwidth" option.),
820 this option should be set to "double" to match the width perceived
821 by Vim with the width of glyphs in the font. Perhaps it also has
Bram Moolenaar8024f932020-01-14 19:29:13 +0100822 to be set to "double" under CJK MS-Windows when the system locale is
823 set to one of CJK locales. See Unicode Standard Annex #11
824 (http://www.unicode.org/reports/tr11).
Bram Moolenaar071d4272004-06-13 20:20:40 +0000825
Bram Moolenaarac7bd632013-03-19 11:35:58 +0100826 Vim may set this option automatically at startup time when Vim is

Bram Moolenaar071d4272004-06-13 20:20:40 +0000837 v10.2 or later. When on, Vim will use smooth ("antialiased") fonts,
838 which can be easier to read at certain sizes on certain displays.
839 Setting this option can sometimes cause problems if 'guifont' is set
840 to its default (empty string).

848 This option can be set to start editing Arabic text.
849 Setting this option will:
850 - Set the 'rightleft' option, unless 'termbidi' is set.
851 - Set the 'arabicshape' option, unless 'termbidi' is set.
852 - Set the 'keymap' option to "arabic"; in Insert mode CTRL-^ toggles
853 between typing English and Arabic key mapping.
854 - Set the 'delcombine' option
855 Note that 'encoding' must be "utf-8" for working with Arabic text.
856
857 Resetting this option will:
858 - Reset the 'rightleft' option.
859 - Disable the use of 'keymap' (without changing its value).
860 Note that 'arabicshape' and 'delcombine' are not reset (it is a global

Bram Moolenaar071d4272004-06-13 20:20:40 +0000874 one which encompasses:
875 a) the changing/morphing of characters based on their location
876 within a word (initial, medial, final and stand-alone).
877 b) the enabling of the ability to compose characters
878 c) the enabling of the required combining of some characters

892 It will change to the directory containing the file which was opened

930 When on, Vim will change the current working directory whenever you
931 change the directory of the shell running in a terminal window. You
932 need proper setting-up, so whenever the shell's pwd changes an OSC 7
933 escape sequence will be emitted. For example, on Linux, you can
934 source /etc/profile.d/vte.sh in your shell profile if you use bash or
935 zsh. For bash this should work (put it in a bash init file): >
936 if [[ -n "$VIM_TERMINAL" ]]; then
937 PROMPT_COMMAND='_vim_sync_PWD'
938 function _vim_sync_PWD() {
939 printf '\033]7;file://%s\033\\' "$PWD"
940 }
941 fi
942<

944 if [[ -n "$VIM_TERMINAL" ]]; then
945 autoload -Uz add-zsh-hook
946 add-zsh-hook -Uz chpwd _vim_sync_PWD
947 function _vim_sync_PWD() {
948 printf '\033]7;file://%s\033\\' "$PWD"

Bram Moolenaar20aac6c2018-09-02 21:07:30 +0200975 "nowrite", "nofile", "terminal" or "prompt".
Bram Moolenaarb7398fe2023-05-14 18:50:25 +0100976 USE WITH CARE: If you make temporary changes to a buffer that you
977 don't want to be saved this option may cause it to be saved anyway.
978 Renaming the buffer with ":file {name}" may help avoid this.

980 *'autowriteall'* *'awa'* *'noautowriteall'* *'noawa'*
981'autowriteall' 'awa' boolean (default off)
982 global
Bram Moolenaar071d4272004-06-13 20:20:40 +0000983 Like 'autowrite', but also used for commands ":edit", ":enew", ":quit",
984 ":qall", ":exit", ":xit", ":recover" and closing the Vim window.
985 Setting this option also implies that Vim behaves like 'autowrite' has
986 been set.
987
988 *'background'* *'bg'*
Bram Moolenaar446beb42011-05-10 17:18:44 +0200989'background' 'bg' string (default "dark" or "light", see below)
Bram Moolenaar071d4272004-06-13 20:20:40 +0000990 global
Bram Moolenaar071d4272004-06-13 20:20:40 +0000991 When set to "dark", Vim will try to use colors that look good on a
992 dark background. When set to "light", Vim will try to use colors that
993 look good on a light background. Any other value is illegal.
994 Vim tries to set the default value according to the terminal used.
995 This will not always be correct.
996 Setting this option does not change the background color, it tells Vim
997 what the background color looks like. For changing the background
998 color, see |:hi-normal|.
999
Gregory Anders83ad2722024-01-03 19:48:51 +01001000 When 'background' is changed Vim will adjust the default color groups
1001 for the new value. But the colors used for syntax highlighting will
1002 not change. *g:colors_name*
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01001003 When a color scheme is loaded (the "g:colors_name" variable is set)
Gregory Anders83ad2722024-01-03 19:48:51 +01001004 changing 'background' will cause the color scheme to be reloaded. If
Bram Moolenaar071d4272004-06-13 20:20:40 +00001005 the color scheme adjusts to the value of 'background' this will work.
1006 However, if the color scheme sets 'background' itself the effect may
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01001007 be undone. First delete the "g:colors_name" variable when needed.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001008
1009 When setting 'background' to the default value with: >
1010 :set background&
1011< Vim will guess the value. In the GUI this should work correctly,
1012 in other cases Vim might not be able to guess the right value.
Bram Moolenaar2e693a82019-10-16 22:35:02 +02001013 If the GUI supports a dark theme, you can use the "d" flag in
Bram Moolenaar50bf7ce2019-09-15 13:17:00 +02001014 'guioptions', see 'go-d'.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001015
Bram Moolenaar37c64c72017-09-19 22:06:03 +02001016 When the |t_RB| option is set, Vim will use it to request the background
Bram Moolenaarb4d6c3e2017-05-27 16:45:17 +02001017 color from the terminal. If the returned RGB value is dark/light and
1018 'background' is not dark/light, 'background' will be set and the
1019 screen is redrawn. This may have side effects, make t_BG empty in
Bram Moolenaar37c64c72017-09-19 22:06:03 +02001020 your .vimrc if you suspect this problem. The response to |t_RB| can
Bram Moolenaar01164a62017-11-02 22:58:42 +01001021 be found in |v:termrbgresp|.
Bram Moolenaarb4d6c3e2017-05-27 16:45:17 +02001022
Bram Moolenaar071d4272004-06-13 20:20:40 +00001023 When starting the GUI, the default value for 'background' will be
1024 "light". When the value is not set in the .gvimrc, and Vim detects
1025 that the background is actually quite dark, 'background' is set to
1026 "dark". But this happens only AFTER the .gvimrc file has been read
1027 (because the window needs to be opened to find the actual background
1028 color). To get around this, force the GUI window to be opened by
1029 putting a ":gui" command in the .gvimrc file, before where the value
1030 of 'background' is used (e.g., before ":syntax on").
Bram Moolenaar446beb42011-05-10 17:18:44 +02001031
Bram Moolenaar6f345a12019-12-17 21:27:18 +01001032 For MS-Windows the default is "dark".
Bram Moolenaar446beb42011-05-10 17:18:44 +02001033 For other systems "dark" is used when 'term' is "linux",
1034 "screen.linux", "cygwin" or "putty", or $COLORFGBG suggests a dark
1035 background. Otherwise the default is "light".
1036
Bram Moolenaarc572da52017-08-27 16:52:01 +02001037 The |:terminal| command and the |term_start()| function use the
1038 'background' value to decide whether the terminal window will start
1039 with a white or black background.
1040
Bram Moolenaar071d4272004-06-13 20:20:40 +00001041 Normally this option would be set in the .vimrc file. Possibly
1042 depending on the terminal name. Example: >
1043 :if &term == "pcterm"
1044 : set background=dark
1045 :endif
1046< When this option is set, the default settings for the highlight groups
1047 will change. To use other settings, place ":highlight" commands AFTER
1048 the setting of the 'background' option.
1049 This option is also used in the "$VIMRUNTIME/syntax/syntax.vim" file
1050 to select the colors for syntax highlighting. After changing this
1051 option, you must load syntax.vim again to see the result. This can be
1052 done with ":syntax on".
1053
1054 *'backspace'* *'bs'*
Bram Moolenaar8c08b5b2016-07-28 22:24:15 +02001055'backspace' 'bs' string (default "", set to "indent,eol,start"
1056 in |defaults.vim|)

1060 a way to backspace over something:
1061 value effect ~
1062 indent allow backspacing over autoindent
1063 eol allow backspacing over line breaks (join lines)
1064 start allow backspacing over the start of insert; CTRL-W and CTRL-U
1065 stop once at the start of insert.
Bram Moolenaaraa0489e2020-04-17 19:41:21 +02001066 nostop like start, except CTRL-W and CTRL-U do not stop at the start of
1067 insert.

Bram Moolenaar46eea442022-03-30 10:51:39 +01001069 When the value is empty, Vi compatible backspacing is used, none of
1070 the ways mentioned for the items above are possible.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001071

1086 file has been successfully written. If you do not want to keep the
1087 backup file, but you do want a backup while the file is being
1088 written, reset this option and set the 'writebackup' option (this is
1089 the default). If you do not want a backup file at all reset both
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00001090 options (use this if your file system is almost full). See the

1092 When the 'backupskip' pattern matches, a backup is not made anyway.
1093 When 'patchmode' is set, the backup may be renamed to become the
1094 oldest version of a file.
1095 NOTE: This option is reset when 'compatible' is set.
1096
1097 *'backupcopy'* *'bkc'*
1098'backupcopy' 'bkc' string (Vi default for Unix: "yes", otherwise: "auto")
Bram Moolenaarb8ee25a2014-09-23 15:45:08 +02001099 global or local to buffer |global-local|
Bram Moolenaar071d4272004-06-13 20:20:40 +00001100 When writing a file and a backup is made, this option tells how it's
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01001101 done. This is a comma-separated list of words.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001102
1103 The main values are:
1104 "yes" make a copy of the file and overwrite the original one
1105 "no" rename the file and write a new one
1106 "auto" one of the previous, what works best
1107
1108 Extra values that can be combined with the ones above are:
1109 "breaksymlink" always break symlinks when writing
1110 "breakhardlink" always break hardlinks when writing
1111
1112 Making a copy and overwriting the original file:
1113 - Takes extra time to copy the file.
1114 + When the file has special attributes, is a (hard/symbolic) link or
1115 has a resource fork, all this is preserved.
1116 - When the file is a link the backup will have the name of the link,
1117 not of the real file.
1118
1119 Renaming the file and writing a new one:
1120 + It's fast.
1121 - Sometimes not all attributes of the file can be copied to the new
1122 file.
1123 - When the file is a link the new file will not be a link.
1124
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01001125 The "auto" value is the middle way: When Vim sees that renaming the
1126 file is possible without side effects (the attributes can be passed on
1127 and the file is not a link) that is used. When problems are expected,
1128 a copy will be made.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001129
1130 The "breaksymlink" and "breakhardlink" values can be used in
1131 combination with any of "yes", "no" and "auto". When included, they
1132 force Vim to always break either symbolic or hard links by doing
1133 exactly what the "no" option does, renaming the original file to
1134 become the backup and writing a new file in its place. This can be
1135 useful for example in source trees where all the files are symbolic or
1136 hard links and any changes should stay in the local source tree, not
1137 be propagated back to the original source.
1138 *crontab*
1139 One situation where "no" and "auto" will cause problems: A program
1140 that opens a file, invokes Vim to edit that file, and then tests if
1141 the open file was changed (through the file descriptor) will check the
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00001142 backup file instead of the newly created file. "crontab -e" is an
Bram Moolenaar071d4272004-06-13 20:20:40 +00001143 example.
1144
1145 When a copy is made, the original file is truncated and then filled
1146 with the new text. This means that protection bits, owner and
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01001147 symbolic links of the original file are unmodified. The backup file,
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00001148 however, is a new file, owned by the user who edited the file. The
Bram Moolenaar071d4272004-06-13 20:20:40 +00001149 group of the backup is set to the group of the original file. If this
1150 fails, the protection bits for the group are made the same as for
1151 others.
1152
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01001153 When the file is renamed, this is the other way around: The backup has
Bram Moolenaar071d4272004-06-13 20:20:40 +00001154 the same attributes of the original file, and the newly written file
1155 is owned by the current user. When the file was a (hard/symbolic)
1156 link, the new file will not! That's why the "auto" value doesn't
1157 rename when the file is a link. The owner and group of the newly
1158 written file will be set to the same ones as the original file, but
1159 the system may refuse to do this. In that case the "auto" value will
1160 again not rename the file.
1161
Bram Moolenaar036986f2017-03-16 17:41:02 +01001162 NOTE: This option is set to the Vi default value when 'compatible' is
1163 set and to the Vim default value when 'compatible' is reset.
1164
Bram Moolenaar071d4272004-06-13 20:20:40 +00001165 *'backupdir'* *'bdir'*
1166'backupdir' 'bdir' string (default for Amiga: ".,t:",
Bram Moolenaar5666fcd2019-12-26 14:35:26 +01001167 for Win32: ".,$TEMP,c:/tmp,c:/temp"
Bram Moolenaar071d4272004-06-13 20:20:40 +00001168 for Unix: ".,~/tmp,~/")
1169 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00001170 List of directories for the backup file, separated with commas.
1171 - The backup file will be created in the first directory in the list
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01001172 where this is possible. The directory must exist, Vim will not
1173 create it for you.
Bram Moolenaar3848e002016-03-19 18:42:29 +01001174 - Empty means that no backup file will be created ('patchmode' is
Bram Moolenaar071d4272004-06-13 20:20:40 +00001175 impossible!). Writing may fail because of this.
1176 - A directory "." means to put the backup file in the same directory
1177 as the edited file.
Bram Moolenaar8024f932020-01-14 19:29:13 +01001178 - A directory starting with "./" (or ".\" for MS-Windows) means to put
1179 the backup file relative to where the edited file is. The leading
1180 "." is replaced with the path name of the edited file.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001181 ("." inside a directory name has no special meaning).
1182 - Spaces after the comma are ignored, other spaces are considered part
1183 of the directory name. To have a space at the start of a directory
1184 name, precede it with a backslash.
1185 - To include a comma in a directory name precede it with a backslash.
1186 - A directory name may end in an '/'.
Bram Moolenaarb782ba42018-08-07 21:39:28 +02001187 - For Unix and Win32, if a directory ends in two path separators "//",
Bram Moolenaarf0d58ef2018-11-16 16:13:44 +01001188 the backup file name will be built from the complete path to the
1189 file with all path separators changed to percent '%' signs. This
1190 will ensure file name uniqueness in the backup directory.
Bram Moolenaarb782ba42018-08-07 21:39:28 +02001191 On Win32, it is also possible to end with "\\". However, When a
1192 separating comma is following, you must use "//", since "\\" will
1193 include the comma in the file name. Therefore it is recommended to
1194 use '//', instead of '\\'.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001195 - Environment variables are expanded |:set_env|.
1196 - Careful with '\' characters, type one before a space, type two to
1197 get one in the option (see |option-backslash|), for example: >
1198 :set bdir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
1199< - For backwards compatibility with Vim version 3.0 a '>' at the start
1200 of the option is removed.
1201 See also 'backup' and 'writebackup' options.
1202 If you want to hide your backup files on Unix, consider this value: >
1203 :set backupdir=./.backup,~/.backup,.,/tmp
1204< You must create a ".backup" directory in each directory and in your
1205 home directory for this to work properly.
1206 The use of |:set+=| and |:set-=| is preferred when adding or removing
1207 directories from the list. This avoids problems when a future version
1208 uses another default.
1209 This option cannot be set from a |modeline| or in the |sandbox|, for
1210 security reasons.

1216 backup file. The default is quite unusual, because this avoids
1217 accidentally overwriting existing files with a backup file. You might
1218 prefer using ".bak", but make sure that you don't have files with
1219 ".bak" that you want to keep.

Bram Moolenaar97b2ad32006-03-18 21:40:56 +00001281 Expression for text to show in evaluation balloon. It is only used
Bram Moolenaara6c27c42019-05-09 19:16:22 +02001282 when 'ballooneval' or 'balloonevalterm' is on. These variables can be
1283 used:
Bram Moolenaare4efc3b2005-03-07 23:16:51 +00001284
1285 v:beval_bufnr number of the buffer in which balloon is going to show

1289 v:beval_col column number (byte index)
1290 v:beval_text word under or after the mouse pointer
1291
Bram Moolenaar54775062019-07-31 21:07:14 +02001292 Instead of showing a balloon, which is limited to plain text, consider
1293 using a popup window, see |popup_beval_example|. A popup window can
1294 use highlighting and show a border.
1295
Bram Moolenaare4efc3b2005-03-07 23:16:51 +00001296 The evaluation of the expression must not have side effects!
1297 Example: >
Bram Moolenaara6c27c42019-05-09 19:16:22 +02001298 function MyBalloonExpr()
Bram Moolenaarc51cf032022-02-26 12:25:45 +00001299 return 'Cursor is at line ' .. v:beval_lnum ..

Bram Moolenaar396e8292019-07-13 23:04:31 +02001307 Also see |balloon_show()|, it can be used if the content of the balloon
1308 is to be fetched asynchronously. In that case evaluating
1309 'balloonexpr' should result in an empty string. If you get a balloon
1310 with only "0" you probably didn't return anything from your function.
Bram Moolenaar214641f2017-03-05 17:04:09 +01001311
Bram Moolenaare4efc3b2005-03-07 23:16:51 +00001312 NOTE: The balloon is displayed only if the cursor is on a text
1313 character. If the result of evaluating 'balloonexpr' is not empty,
1314 Vim does not try to send a message to an external debugger (Netbeans
1315 or Sun Workshop).
1316
Yegappan Lakshmanan8bb65f22021-12-26 10:51:39 +00001317 If the expression starts with s: or |<SID>|, then it is replaced with
1318 the script ID (|local-function|). Example: >
1319 set bexpr=s:MyBalloonExpr()
1320 set bexpr=<SID>SomeBalloonExpr()
Bram Moolenaar6f4754b2022-01-23 12:07:04 +00001321< Otherwise, the expression is evaluated in the context of the script
1322 where the option was set, thus script-local items are available.
1323
Bram Moolenaar30b65812012-07-12 22:01:11 +02001324 The expression will be evaluated in the |sandbox| when set from a
1325 modeline, see |sandbox-option|.
Bram Moolenaar110289e2019-05-23 15:38:06 +02001326 This option cannot be set in a modeline when 'modelineexpr' is off.

Bram Moolenaarb71eaae2006-01-20 23:10:18 +00001330
Bram Moolenaar87e25fd2005-07-27 21:13:01 +00001331 To check whether line breaks in the balloon text work use this check: >
Bram Moolenaar45360022005-07-21 21:08:21 +00001332 if has("balloon_multiline")
Bram Moolenaar362e1a32006-03-06 23:29:24 +00001333< When they are supported "\n" characters will start a new line. If the
1334 expression evaluates to a |List| this is equal to using each List item
1335 as a string and putting "\n" in between them.
Bram Moolenaar036986f2017-03-16 17:41:02 +01001336 NOTE: This option is set to "" when 'compatible' is set.

Bram Moolenaar036986f2017-03-16 17:41:02 +01001375 This is most useful to fine tune when in Insert mode the bell should

1381'binary' 'bin' boolean (default off)
1382 local to buffer
Bram Moolenaar071d4272004-06-13 20:20:40 +00001383 This option should be set before editing a binary file. You can also
1384 use the |-b| Vim argument. When this option is switched on a few
1385 options will be changed (also when it already was on):
1386 'textwidth' will be set to 0
1387 'wrapmargin' will be set to 0
1388 'modeline' will be off
1389 'expandtab' will be off
1390 Also, 'fileformat' and 'fileformats' options will not be used, the
1391 file is read and written like 'fileformat' was "unix" (a single <NL>
1392 separates lines).
1393 The 'fileencoding' and 'fileencodings' options will not be used, the
1394 file is read without conversion.
1395 NOTE: When you start editing a(nother) file while the 'bin' option is
1396 on, settings from autocommands may change the settings again (e.g.,
1397 'textwidth'), causing trouble when editing. You might want to set
1398 'bin' again when the file has been loaded.
1399 The previous values of these options are remembered and restored when
1400 'bin' is switched from on to off. Each buffer has its own set of
1401 saved option values.
1402 To edit a file with 'binary' set you can use the |++bin| argument.
1403 This avoids you have to do ":set bin", which would have effect for all
1404 files you edit.
1405 When writing a file the <EOL> for the last line is only written if
1406 there was one in the original file (normally Vim appends an <EOL> to
1407 the last line if there is none; this would make the file longer). See
1408 the 'endofline' option.

1418 local to buffer
Bram Moolenaar071d4272004-06-13 20:20:40 +00001419 When writing a file and the following conditions are met, a BOM (Byte
1420 Order Mark) is prepended to the file:
1421 - this option is on
1422 - the 'binary' option is off
1423 - 'fileencoding' is "utf-8", "ucs-2", "ucs-4" or one of the little/big
1424 endian variants.
1425 Some applications use the BOM to recognize the encoding of the file.
1426 Often used for UCS-2 files on MS-Windows. For other applications it
1427 causes trouble, for example: "cat file1 file2" makes the BOM of file2
njohnstonaabca252023-11-19 23:18:57 +00001428 appear halfway through the resulting file. Gcc doesn't accept a BOM.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001429 When Vim reads a file and 'fileencodings' starts with "ucs-bom", a
1430 check for the presence of the BOM is done and 'bomb' set accordingly.
1431 Unless 'binary' is set, it is removed from the first line, so that you
1432 don't see it when editing. When you don't change the options, the BOM
1433 will be restored when writing the file.

1552 This option is used together with 'bufhidden' and 'swapfile' to
1553 specify special kinds of buffers. See |special-buffers|.
Bram Moolenaarebdf3c92020-02-15 21:41:42 +01001554 Also see |win_gettype()|, which returns the type of the window.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001555
1556 Be careful with changing this option, it can have many side effects!
Bram Moolenaar113cb512021-11-07 20:27:04 +00001557 One such effect is that Vim will not check the timestamp of the file,
1558 if the file is changed by another program this will not be noticed.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001559
Bram Moolenaar280f1262006-01-30 00:14:18 +00001560 A "quickfix" buffer is only used for the error list and the location
1561 list. This value is set by the |:cwindow| and |:lwindow| commands and
1562 you are not supposed to change it.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001563
1564 "nofile" and "nowrite" buffers are similar:
1565 both: The buffer is not to be written to disk, ":w" doesn't
1566 work (":w filename" does work though).
1567 both: The buffer is never considered to be |'modified'|.
1568 There is no warning when the changes will be lost, for
1569 example when you quit Vim.
1570 both: A swap file is only created when using too much memory
1571 (when 'swapfile' has been reset there is never a swap
1572 file).
1573 nofile only: The buffer name is fixed, it is not handled like a
1574 file name. It is not modified in response to a |:cd|
1575 command.
Bram Moolenaar2b8388b2015-02-28 13:11:45 +01001576 both: When using ":e bufname" and already editing "bufname"
1577 the buffer is made empty and autocommands are
1578 triggered as usual for |:edit|.
Bram Moolenaar21cf8232004-07-16 20:18:37 +00001579 *E676*
1580 "acwrite" implies that the buffer name is not related to a file, like
1581 "nofile", but it will be written. Thus, in contrast to "nofile" and
1582 "nowrite", ":w" does work and a modified buffer can't be abandoned
1583 without saving. For writing there must be matching |BufWriteCmd|,
1584 |FileWriteCmd| or |FileAppendCmd| autocommands.

1588 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00001589 Specifies details about changing the case of letters. It may contain
1590 these words, separated by a comma:
1591 internal Use internal case mapping functions, the current
1592 locale does not change the case mapping. This only
Bram Moolenaar6f16eb82005-08-23 21:02:42 +00001593 matters when 'encoding' is a Unicode encoding,
1594 "latin1" or "iso-8859-15". When "internal" is
1595 omitted, the towupper() and towlower() system library
1596 functions are used when available.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001597 keepascii For the ASCII characters (0x00 to 0x7f) use the US
1598 case mapping, the current locale is not effective.
1599 This probably only matters for Turkish.

1603 global
1604 When on, |:cd|, |:tcd| and |:lcd| without an argument changes the
1605 current working directory to the |$HOME| directory like in Unix.
1606 When off, those commands just print the current directory name.
1607 On Unix this option has no effect.
dkearns8ebdbc92023-10-29 06:26:19 +11001608 This option cannot be set from a |modeline| or in the |sandbox|, for

Bram Moolenaar071d4272004-06-13 20:20:40 +00001612 *'cdpath'* *'cd'* *E344* *E346*
1613'cdpath' 'cd' string (default: equivalent to $CDPATH or ",,")
1614 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00001615 This is a list of directories which will be searched when using the
Bram Moolenaar00aa0692019-04-27 20:37:57 +02001616 |:cd|, |:tcd| and |:lcd| commands, provided that the directory being
1617 searched for has a relative path, not an absolute part starting with
1618 "/", "./" or "../", the 'cdpath' option is not used then.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001619 The 'cdpath' option's value has the same form and semantics as
1620 |'path'|. Also see |file-searching|.
1621 The default value is taken from $CDPATH, with a "," prepended to look
1622 in the current directory first.
1623 If the default value taken from $CDPATH is not what you want, include
1624 a modified version of the following command in your vimrc file to
1625 override it: >
Bram Moolenaarc51cf032022-02-26 12:25:45 +00001626 :let &cdpath = ',' .. substitute(substitute($CDPATH, '[, ]', '\\\0', 'g'), ':', ',', 'g')

1630
1631 *'cedit'*
1632'cedit' string (Vi default: "", Vim default: CTRL-F)
1633 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00001634 The key used in Command-line Mode to open the command-line window.
1635 The default is CTRL-F when 'compatible' is off.
1636 Only non-printable keys are allowed.
1637 The key can be specified as a single character, but it is difficult to
1638 type. The preferred way is to use the <> notation. Examples: >
Bram Moolenaare18dbe82016-07-02 21:42:23 +02001639 :exe "set cedit=\<C-Y>"
1640 :exe "set cedit=\<Esc>"
Bram Moolenaar071d4272004-06-13 20:20:40 +00001641< |Nvi| also has this option, but it only uses the first character.
1642 See |cmdwin|.
Bram Moolenaar036986f2017-03-16 17:41:02 +01001643 NOTE: This option is set to the Vim default value when 'compatible'
1644 is reset.

1646 *'charconvert'* *'ccv'* *E202* *E214* *E513*
1647'charconvert' 'ccv' string (default "")
1648 global
Bram Moolenaar4c92e752019-02-17 21:18:32 +01001649 {only available when compiled with the |+eval| feature}
Bram Moolenaar071d4272004-06-13 20:20:40 +00001650 An expression that is used for character encoding conversion. It is
1651 evaluated when a file that is to be read or has been written has a
1652 different encoding from what is desired.
1653 'charconvert' is not used when the internal iconv() function is
1654 supported and is able to do the conversion. Using iconv() is
1655 preferred, because it is much faster.
1656 'charconvert' is not used when reading stdin |--|, because there is no
1657 file to convert from. You will have to save the text in a file first.
Bram Moolenaarf10911e2022-01-29 22:20:48 +00001658 The expression must return zero, false or an empty string for success,
1659 non-zero or true for failure.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001660 The possible encoding names encountered are in 'encoding'.
1661 Additionally, names given in 'fileencodings' and 'fileencoding' are
1662 used.
1663 Conversion between "latin1", "unicode", "ucs-2", "ucs-4" and "utf-8"
1664 is done internally by Vim, 'charconvert' is not used for this.
1665 'charconvert' is also used to convert the viminfo file, if the 'c'
1666 flag is present in 'viminfo'. Also used for Unicode conversion.
1667 Example: >
1668 set charconvert=CharConvert()
1669 fun CharConvert()
1670 system("recode "
Bram Moolenaarc51cf032022-02-26 12:25:45 +00001671 \ .. v:charconvert_from .. ".." .. v:charconvert_to
1672 \ .. " <" .. v:fname_in .. " >" .. v:fname_out)
Bram Moolenaar071d4272004-06-13 20:20:40 +00001673 return v:shell_error
1674 endfun
1675< The related Vim variables are:
1676 v:charconvert_from name of the current encoding
1677 v:charconvert_to name of the desired encoding
1678 v:fname_in name of the input file
1679 v:fname_out name of the output file
1680 Note that v:fname_in and v:fname_out will never be the same.
1681 Note that v:charconvert_from and v:charconvert_to may be different
1682 from 'encoding'. Vim internally uses UTF-8 instead of UCS-2 or UCS-4.
Bram Moolenaarf10911e2022-01-29 22:20:48 +00001683
Bram Moolenaara4e0b972022-10-01 19:43:52 +01001684 The advantage of using a function call without arguments is that it is
1685 faster, see |expr-option-function|.
1686
Bram Moolenaar071d4272004-06-13 20:20:40 +00001687 Encryption is not done by Vim when using 'charconvert'. If you want
1688 to encrypt the file after conversion, 'charconvert' should take care
1689 of this.
Bram Moolenaarf10911e2022-01-29 22:20:48 +00001690
1691 If the 'charconvert' expression starts with s: or |<SID>|, then it is
1692 replaced with the script ID (|local-function|). Example: >
1693 set charconvert=s:MyConvert()
1694 set charconvert=<SID>SomeConvert()
1695< Otherwise the expression is evaluated in the context of the script
1696 where the option was set, thus script-local items are available.
1697
Bram Moolenaar071d4272004-06-13 20:20:40 +00001698 This option cannot be set from a |modeline| or in the |sandbox|, for
1699 security reasons.

1703 local to buffer
Bram Moolenaar446cb832008-06-24 21:56:24 +00001704 Enables automatic C program indenting. See 'cinkeys' to set the keys
Bram Moolenaar071d4272004-06-13 20:20:40 +00001705 that trigger reindenting in insert mode and 'cinoptions' to set your
1706 preferred indent style.
1707 If 'indentexpr' is not empty, it overrules 'cindent'.
1708 If 'lisp' is not on and both 'indentexpr' and 'equalprg' are empty,
1709 the "=" operator indents using this algorithm rather than calling an
1710 external program.
1711 See |C-indenting|.
1712 When you don't like the way 'cindent' works, try the 'smartindent'
1713 option or 'indentexpr'.
1714 This option is not used when 'paste' is set.
1715 NOTE: This option is reset when 'compatible' is set.

1735 local to buffer
1736 Keywords that are interpreted as a C++ scope declaration by |cino-g|.
1737 Useful e.g. for working with the Qt framework that defines additional

Bram Moolenaar071d4272004-06-13 20:20:40 +00001744 These keywords start an extra indent in the next line when
1745 'smartindent' or 'cindent' is set. For 'cindent' this is only done at
1746 an appropriate place (inside {}).
1747 Note that 'ignorecase' isn't used for 'cinwords'. If case doesn't
1748 matter, include the keyword both the uppercase and lowercase:
1749 "if,If,IF".

Tom Praschan3506cf32022-04-07 12:39:08 +01001757 This option is a list of comma-separated names.
Bram Moolenaar942db232021-02-13 18:14:48 +01001758 Note: if one of the items is "exclude:", then you can't add an item
Bram Moolenaar5ed11532022-07-06 13:18:11 +01001759 after that. Therefore do not append an item with += but use ^= to
Bram Moolenaar942db232021-02-13 18:14:48 +01001760 prepend, e.g.: >

Bram Moolenaarc0885aa2012-07-10 16:49:23 +02001765 *clipboard-unnamed*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001766 unnamed When included, Vim will use the clipboard register '*'
1767 for all yank, delete, change and put operations which
1768 would normally go to the unnamed register. When a
1769 register is explicitly specified, it will always be
1770 used regardless of whether "unnamed" is in 'clipboard'
1771 or not. The clipboard register can always be
1772 explicitly accessed using the "* notation. Also see

Bram Moolenaar00154502013-02-13 16:15:55 +01001776 unnamedplus A variant of the "unnamed" flag which uses the
1777 clipboard register '+' (|quoteplus|) instead of
1778 register '*' for all yank, delete, change and put
1779 operations which would normally go to the unnamed
1780 register. When "unnamed" is also included to the
1781 option, yank operations (but not delete, change or
1782 put) will additionally copy the text into register
1783 '*'.
Bram Moolenaar81af9252010-12-10 20:35:50 +01001784 Only available with the |+X11| feature.

Bram Moolenaar071d4272004-06-13 20:20:40 +00001789 autoselect Works like the 'a' flag in 'guioptions': If present,
1790 then whenever Visual mode is started, or the Visual
1791 area extended, Vim tries to become the owner of the
1792 windowing system's global selection or put the
1793 selected text on the clipboard used by the selection
Bram Moolenaarba3ff532018-11-04 14:45:49 +01001794 register "*. See |'go-a'| and |quotestar| for details.
1795 When the GUI is active, the 'a' flag in 'guioptions'
1796 is used, when the GUI is not active, this "autoselect"
1797 flag is used.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001798 Also applies to the modeless selection.
1799
Bram Moolenaarc0885aa2012-07-10 16:49:23 +02001800 *clipboard-autoselectplus*
1801 autoselectplus Like "autoselect" but using the + register instead of
1802 the * register. Compare to the 'P' flag in
1803 'guioptions'.
1804
1805 *clipboard-autoselectml*
Bram Moolenaar071d4272004-06-13 20:20:40 +00001806 autoselectml Like "autoselect", but for the modeless selection
1807 only. Compare to the 'A' flag in 'guioptions'.
1808
Bram Moolenaarc0885aa2012-07-10 16:49:23 +02001809 *clipboard-html*
Bram Moolenaar3a6eaa52009-06-16 13:23:06 +00001810 html When the clipboard contains HTML, use this when
1811 pasting. When putting text on the clipboard, mark it
1812 as HTML. This works to copy rendered HTML from
1813 Firefox, paste it as raw HTML in Vim, select the HTML
1814 in Vim and paste it in a rich edit box in Firefox.
Bram Moolenaar20a825a2010-05-31 21:27:30 +02001815 You probably want to add this only temporarily,
1816 possibly use BufEnter autocommands.
Bram Moolenaar3a6eaa52009-06-16 13:23:06 +00001817 Only supported for GTK version 2 and later.

Bram Moolenaar071d4272004-06-13 20:20:40 +00001820 exclude:{pattern}
1821 Defines a pattern that is matched against the name of
1822 the terminal 'term'. If there is a match, no
1823 connection will be made to the X server. This is
1824 useful in this situation:
1825 - Running Vim in a console.
1826 - $DISPLAY is set to start applications on another
1827 display.
1828 - You do not want to connect to the X server in the
1829 console, but do want this in a terminal emulator.
1830 To never connect to the X server use: >
1831 exclude:.*
1832< This has the same effect as using the |-X| argument.
1833 Note that when there is no connection to the X server
1834 the window title won't be restored and the clipboard
1835 cannot be accessed.
1836 The value of 'magic' is ignored, {pattern} is
1837 interpreted as if 'magic' was on.
1838 The rest of the option value will be used for
1839 {pattern}, this must be the last entry.

Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01001859 'colorcolumn' is a comma-separated list of screen columns that are
Bram Moolenaar483c5d82010-10-20 18:45:33 +02001860 highlighted with ColorColumn |hl-ColorColumn|. Useful to align
1861 text. Will make screen redrawing slower.

Bram Moolenaar7c626922005-02-07 22:01:03 +00001876 initialization and does not have to be set by hand. Also see
1877 |posix-screen-size|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001878 When Vim is running in the GUI or in a resizable window, setting this
1879 option will cause the window size to be changed. When you only want
1880 to use the size for the GUI, put the command in your |gvimrc| file.
1881 When you set this option and Vim is unable to change the physical
Bram Moolenaar02467872007-05-06 13:22:01 +00001882 number of columns of the display, the display may be messed up. For
1883 the GUI it is always possible and Vim limits the number of columns to
1884 what fits on the screen. You can use this command to get the widest
1885 window possible: >

Bram Moolenaar071d4272004-06-13 20:20:40 +00001910 This option has the effect of making Vim either more Vi-compatible, or
1911 make Vim behave in a more useful way.
Bram Moolenaar214641f2017-03-05 17:04:09 +01001912
Bram Moolenaar071d4272004-06-13 20:20:40 +00001913 This is a special kind of option, because when it's set or reset,
Bram Moolenaar214641f2017-03-05 17:04:09 +01001914 other options are also changed as a side effect.
1915 NOTE: Setting or resetting this option can have a lot of unexpected
1916 effects: Mappings are interpreted in another way, undo behaves
1917 differently, etc. If you set this option in your vimrc file, you
1918 should probably put it at the very start.
1919
Bram Moolenaar071d4272004-06-13 20:20:40 +00001920 By default this option is on and the Vi defaults are used for the
1921 options. This default was chosen for those people who want to use Vim
1922 just like Vi, and don't even (want to) know about the 'compatible'
1923 option.
Bram Moolenaar910f66f2006-04-05 20:41:53 +00001924 When a |vimrc| or |gvimrc| file is found while Vim is starting up,
Bram Moolenaard042c562005-06-30 22:04:15 +00001925 this option is switched off, and all options that have not been
1926 modified will be set to the Vim defaults. Effectively, this means
Bram Moolenaar910f66f2006-04-05 20:41:53 +00001927 that when a |vimrc| or |gvimrc| file exists, Vim will use the Vim
Bram Moolenaard042c562005-06-30 22:04:15 +00001928 defaults, otherwise it will use the Vi defaults. (Note: This doesn't
Bram Moolenaar02467872007-05-06 13:22:01 +00001929 happen for the system-wide vimrc or gvimrc file, nor for a file given
1930 with the |-u| argument). Also see |compatible-default| and
1931 |posix-compliance|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00001932 You can also set this option with the "-C" argument, and reset it with
1933 "-N". See |-C| and |-N|.
Bram Moolenaar214641f2017-03-05 17:04:09 +01001934 See 'cpoptions' for more fine tuning of Vi compatibility.

Bram Moolenaar214641f2017-03-05 17:04:09 +01001936 When this option is set, numerous other options are set to make Vim as
1937 Vi-compatible as possible. When this option is unset, various options
1938 are set to make Vim more useful. The table below lists all the
1939 options affected.
1940 The {?} column indicates when the options are affected:
1941 + Means that the option is set to the value given in {set value} when
1942 'compatible' is set.
1943 & Means that the option is set to the value given in {set value} when
1944 'compatible' is set AND is set to its Vim default value when
1945 'compatible' is unset.
1946 - Means the option is NOT changed when setting 'compatible' but IS
1947 set to its Vim default when 'compatible' is unset.
1948 The {effect} column summarises the change when 'compatible' is set.

Bram Moolenaar0c0734d2019-11-26 21:44:46 +01002118 Just like "popup" but initially hide the popup. Use a
Bram Moolenaardca7abe2019-10-20 18:17:57 +02002119 |CompleteChanged| autocommand to fetch the info and call
2120 |popup_show()| once the popup has been filled.
2121 See the example at |complete-popuphidden|.

Bram Moolenaarb6be1e22015-07-10 18:18:40 +02002124 noinsert Do not insert any text for a match until the user selects
2125 a match from the menu. Only works in combination with
2126 "menu" or "menuone". No effect if "longest" is present.
2127
2128 noselect Do not select a match in the menu, force the user to
2129 select one from the menu. Only works in combination with
2130 "menu" or "menuone".

2137 When 'completeopt' contains "popup" then this option is used for the
Bram Moolenaar447bfba2020-07-18 16:07:16 +02002138 properties of the info popup when it is created. If an info popup
2139 window already exists it is closed, so that the option value is
2140 applied when it is created again.
2141 You can also use |popup_findinfo()| and then set properties for an
2142 existing info popup with |popup_setoptions()|. See |complete-popup|.

2146 local to buffer
2147 {only for MS-Windows}
2148 When this option is set it overrules 'shellslash' for completion:
2149 - When this option is set to "slash", a forward slash is used for path
2150 completion in insert mode. This is useful when editing HTML tag, or
2151 Makefile with 'noshellslash' on MS-Windows.
2152 - When this option is set to "backslash", backslash is used. This is
2153 useful when editing a batch file with 'shellslash' set on MS-Windows.
2154 - When this option is empty, same character is used as for
2155 'shellslash'.
2156 For Insert mode completion the buffer-local value is used. For
2157 command line completion the global value is used.

Bram Moolenaarca8c9862010-07-24 15:00:38 +02002173 A useful value is "nc". This is used in help files. So long as you
Bram Moolenaarf5963f72010-07-23 22:10:27 +02002174 are moving around text is concealed, but when starting to insert text
2175 or selecting a Visual area the concealed text is displayed, so that
2176 you can see what you are doing.
Bram Moolenaarf70e3d62010-07-24 13:15:07 +02002177 Keep in mind that the cursor position is not always where it's

2192 replacement character defined (see |:syn-cchar|) the
2193 character defined in 'listchars' is used (default is a
2194 space).
2195 It is highlighted with the "Conceal" highlight group.
Bram Moolenaar860cae12010-06-05 23:22:07 +02002196 2 Concealed text is completely hidden unless it has a

Bram Moolenaar071d4272004-06-13 20:20:40 +00002208 When 'confirm' is on, certain operations that would normally
2209 fail because of unsaved changes to a buffer, e.g. ":q" and ":e",
2210 instead raise a |dialog| asking if you wish to save the current
2211 file(s). You can still use a ! to unconditionally |abandon| a buffer.
2212 If 'confirm' is off you can still activate confirmation for one
2213 command only (this is most useful in mappings) with the |:confirm|

Bram Moolenaar071d4272004-06-13 20:20:40 +00002225 Copy the structure of the existing lines indent when autoindenting a
2226 new line. Normally the new indent is reconstructed by a series of
2227 tabs followed by spaces as required (unless |'expandtab'| is enabled,
2228 in which case only spaces are used). Enabling this option makes the
2229 new line copy whatever characters were used for indenting on the
Bram Moolenaar446cb832008-06-24 21:56:24 +00002230 existing line. 'expandtab' has no effect on these characters, a Tab
2231 remains a Tab. If the new indent is greater than on the existing
Bram Moolenaar071d4272004-06-13 20:20:40 +00002232 line, the remaining space is filled in the normal manner.
Bram Moolenaar036986f2017-03-16 17:41:02 +01002233 NOTE: This option is reset when 'compatible' is set.

2238 Vi default: all flags)
2239 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00002240 A sequence of single character flags. When a character is present
Bram Moolenaar7cba6c02013-09-05 22:13:31 +02002241 this indicates Vi-compatible behavior. This is used for things where
2242 not being Vi-compatible is mostly or sometimes preferred.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002243 'cpoptions' stands for "compatible-options".
2244 Commas can be added for readability.
2245 To avoid problems with flags that are added in the future, use the
2246 "+=" and "-=" feature of ":set" |add-option-flags|.
Bram Moolenaar71eb3ad2021-12-26 12:07:30 +00002247
Bram Moolenaar071d4272004-06-13 20:20:40 +00002248 NOTE: This option is set to the Vi default value when 'compatible' is
2249 set and to the Vim default value when 'compatible' is reset.
Bram Moolenaar71eb3ad2021-12-26 12:07:30 +00002250
2251 NOTE: In a |Vim9| script, when `vim9script` is encountered, the value
2252 is saved, 'cpoptions' is set to the Vim default, and the saved value
2253 is restored at the end of the script. Changes to the value of
2254 'cpoptions' will be applied to the saved value, but keep in mind that
2255 removing a flag that is not present when 'cpoptions' is changed has no
2256 effect. In the |.vimrc| file the value is not restored, thus using
2257 `vim9script` in the |.vimrc| file results in using the Vim default.
2258
Bram Moolenaar4399ef42005-02-12 14:29:27 +00002259 NOTE: This option is set to the POSIX default value at startup when
2260 the Vi default value would be used and the $VIM_POSIX environment
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01002261 variable exists |posix|. This means Vim tries to behave like the
2262 POSIX specification.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002263
2264 contains behavior ~
2265 *cpo-a*
2266 a When included, a ":read" command with a file name
2267 argument will set the alternate file name for the
2268 current window.
2269 *cpo-A*
2270 A When included, a ":write" command with a file name
2271 argument will set the alternate file name for the
2272 current window.
2273 *cpo-b*
2274 b "\|" in a ":map" command is recognized as the end of
2275 the map command. The '\' is included in the mapping,
2276 the text after the '|' is interpreted as the next
2277 command. Use a CTRL-V instead of a backslash to
2278 include the '|' in the mapping. Applies to all
2279 mapping, abbreviation, menu and autocmd commands.
2280 See also |map_bar|.
2281 *cpo-B*
2282 B A backslash has no special meaning in mappings,
Bram Moolenaara9604e62018-07-21 05:56:22 +02002283 abbreviations, user commands and the "to" part of the
2284 menu commands. Remove this flag to be able to use a
2285 backslash like a CTRL-V. For example, the command
2286 ":map X \<Esc>" results in X being mapped to:
Bram Moolenaar071d4272004-06-13 20:20:40 +00002287 'B' included: "\^[" (^[ is a real <Esc>)
2288 'B' excluded: "<Esc>" (5 characters)
2289 ('<' excluded in both cases)
2290 *cpo-c*
2291 c Searching continues at the end of any match at the
2292 cursor position, but not further than the start of the
2293 next line. When not present searching continues
2294 one character from the cursor position. With 'c'
2295 "abababababab" only gets three matches when repeating
2296 "/abab", without 'c' there are five matches.
2297 *cpo-C*
2298 C Do not concatenate sourced lines that start with a
2299 backslash. See |line-continuation|.
2300 *cpo-d*
2301 d Using "./" in the 'tags' option doesn't mean to use
2302 the tags file relative to the current file, but the
2303 tags file in the current directory.
2304 *cpo-D*
2305 D Can't use CTRL-K to enter a digraph after Normal mode
2306 commands with a character argument, like |r|, |f| and
2307 |t|.
2308 *cpo-e*
2309 e When executing a register with ":@r", always add a
2310 <CR> to the last line, also when the register is not
2311 linewise. If this flag is not present, the register
2312 is not linewise and the last line does not end in a
2313 <CR>, then the last line is put on the command-line
2314 and can be edited before hitting <CR>.
2315 *cpo-E*
2316 E It is an error when using "y", "d", "c", "g~", "gu" or
2317 "gU" on an Empty region. The operators only work when
Bram Moolenaar15142e22018-04-30 22:19:58 +02002318 at least one character is to be operated on. Example:
Bram Moolenaar071d4272004-06-13 20:20:40 +00002319 This makes "y0" fail in the first column.
2320 *cpo-f*
2321 f When included, a ":read" command with a file name
2322 argument will set the file name for the current buffer,
2323 if the current buffer doesn't have a file name yet.
2324 *cpo-F*
2325 F When included, a ":write" command with a file name
2326 argument will set the file name for the current
2327 buffer, if the current buffer doesn't have a file name
Bram Moolenaarb3480382005-12-11 21:33:32 +00002328 yet. Also see |cpo-P|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002329 *cpo-g*
2330 g Goto line 1 when using ":edit" without argument.
Bram Moolenaar4399ef42005-02-12 14:29:27 +00002331 *cpo-H*
2332 H When using "I" on a line with only blanks, insert
2333 before the last blank. Without this flag insert after
2334 the last blank.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002335 *cpo-i*
2336 i When included, interrupting the reading of a file will
2337 leave it modified.
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00002338 *cpo-I*
2339 I When moving the cursor up or down just after inserting
2340 indent for 'autoindent', do not delete the indent.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002341 *cpo-j*
2342 j When joining lines, only add two spaces after a '.',
2343 not after '!' or '?'. Also see 'joinspaces'.
2344 *cpo-J*
2345 J A |sentence| has to be followed by two spaces after
Bram Moolenaar582fd852005-03-28 20:58:01 +00002346 the '.', '!' or '?'. A <Tab> is not recognized as
Bram Moolenaar071d4272004-06-13 20:20:40 +00002347 white space.
2348 *cpo-k*
2349 k Disable the recognition of raw key codes in
2350 mappings, abbreviations, and the "to" part of menu
2351 commands. For example, if <Key> sends ^[OA (where ^[
2352 is <Esc>), the command ":map X ^[OA" results in X
2353 being mapped to:
2354 'k' included: "^[OA" (3 characters)
2355 'k' excluded: "<Key>" (one key code)
2356 Also see the '<' flag below.
2357 *cpo-K*
2358 K Don't wait for a key code to complete when it is
2359 halfway a mapping. This breaks mapping <F1><F1> when
2360 only part of the second <F1> has been read. It
2361 enables cancelling the mapping by typing <F1><Esc>.
2362 *cpo-l*
2363 l Backslash in a [] range in a search pattern is taken
Bram Moolenaar26a60b42005-02-22 08:49:11 +00002364 literally, only "\]", "\^", "\-" and "\\" are special.
2365 See |/[]|
Bram Moolenaar071d4272004-06-13 20:20:40 +00002366 'l' included: "/[ \t]" finds <Space>, '\' and 't'
2367 'l' excluded: "/[ \t]" finds <Space> and <Tab>
Bram Moolenaar26a60b42005-02-22 08:49:11 +00002368 Also see |cpo-\|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002369 *cpo-L*
2370 L When the 'list' option is set, 'wrapmargin',
2371 'textwidth', 'softtabstop' and Virtual Replace mode
2372 (see |gR|) count a <Tab> as two characters, instead of
2373 the normal behavior of a <Tab>.
2374 *cpo-m*
2375 m When included, a showmatch will always wait half a
2376 second. When not included, a showmatch will wait half
2377 a second or until a character is typed. |'showmatch'|
2378 *cpo-M*
2379 M When excluded, "%" matching will take backslashes into
2380 account. Thus in "( \( )" and "\( ( \)" the outer
2381 parenthesis match. When included "%" ignores
2382 backslashes, which is Vi compatible.
2383 *cpo-n*
Bram Moolenaar64486672010-05-16 15:46:46 +02002384 n When included, the column used for 'number' and
2385 'relativenumber' will also be used for text of wrapped
2386 lines.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002387 *cpo-o*
2388 o Line offset to search command is not remembered for
2389 next search.
2390 *cpo-O*
2391 O Don't complain if a file is being overwritten, even
2392 when it didn't exist when editing it. This is a
2393 protection against a file unexpectedly created by
2394 someone else. Vi didn't complain about this.
2395 *cpo-p*
2396 p Vi compatible Lisp indenting. When not present, a
2397 slightly better algorithm is used.
Bram Moolenaarb3480382005-12-11 21:33:32 +00002398 *cpo-P*
2399 P When included, a ":write" command that appends to a
2400 file will set the file name for the current buffer, if
2401 the current buffer doesn't have a file name yet and
2402 the 'F' flag is also included |cpo-F|.
Bram Moolenaar4399ef42005-02-12 14:29:27 +00002403 *cpo-q*
2404 q When joining multiple lines leave the cursor at the
2405 position where it would be when joining two lines.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002406 *cpo-r*
2407 r Redo ("." command) uses "/" to repeat a search
2408 command, instead of the actually used search string.
2409 *cpo-R*
2410 R Remove marks from filtered lines. Without this flag
2411 marks are kept like |:keepmarks| was used.
2412 *cpo-s*
2413 s Set buffer options when entering the buffer for the
2414 first time. This is like it is in Vim version 3.0.
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00002415 And it is the default. If not present the options are
Bram Moolenaar071d4272004-06-13 20:20:40 +00002416 set when the buffer is created.
2417 *cpo-S*
2418 S Set buffer options always when entering a buffer
2419 (except 'readonly', 'fileformat', 'filetype' and
2420 'syntax'). This is the (most) Vi compatible setting.
2421 The options are set to the values in the current
2422 buffer. When you change an option and go to another
2423 buffer, the value is copied. Effectively makes the
2424 buffer options global to all buffers.
2425
2426 's' 'S' copy buffer options
2427 no no when buffer created
2428 yes no when buffer first entered (default)
2429 X yes each time when buffer entered (vi comp.)
2430 *cpo-t*
2431 t Search pattern for the tag command is remembered for
2432 "n" command. Otherwise Vim only puts the pattern in
2433 the history for search pattern, but doesn't change the
2434 last used search pattern.
2435 *cpo-u*
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00002436 u Undo is Vi compatible. See |undo-two-ways|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002437 *cpo-v*
2438 v Backspaced characters remain visible on the screen in
2439 Insert mode. Without this flag the characters are
2440 erased from the screen right away. With this flag the
2441 screen newly typed text overwrites backspaced
2442 characters.
2443 *cpo-w*
2444 w When using "cw" on a blank character, only change one
2445 character and not all blanks until the start of the
2446 next word.
2447 *cpo-W*
2448 W Don't overwrite a readonly file. When omitted, ":w!"
2449 overwrites a readonly file, if possible.
2450 *cpo-x*
2451 x <Esc> on the command-line executes the command-line.
2452 The default in Vim is to abandon the command-line,
2453 because <Esc> normally aborts a command. |c_<Esc>|
Bram Moolenaar4399ef42005-02-12 14:29:27 +00002454 *cpo-X*
2455 X When using a count with "R" the replaced text is
2456 deleted only once. Also when repeating "R" with "."
2457 and a count.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002458 *cpo-y*
Bram Moolenaard09091d2019-01-17 16:07:22 +01002459 y A yank command can be redone with ".". Think twice if
2460 you really want to use this, it may break some
2461 plugins, since most people expect "." to only repeat a
2462 change.
Bram Moolenaar4399ef42005-02-12 14:29:27 +00002463 *cpo-Z*
2464 Z When using "w!" while the 'readonly' option is set,
2465 don't reset 'readonly'.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002466 *cpo-!*
2467 ! When redoing a filter command, use the last used
2468 external command, whatever it was. Otherwise the last
2469 used -filter- command is used.
2470 *cpo-$*
2471 $ When making a change to one line, don't redisplay the
2472 line, but put a '$' at the end of the changed text.
2473 The changed text will be overwritten when you type the
2474 new text. The line is redisplayed if you type any
2475 command that moves the cursor from the insertion
2476 point.
2477 *cpo-%*
2478 % Vi-compatible matching is done for the "%" command.
2479 Does not recognize "#if", "#endif", etc.
2480 Does not recognize "/*" and "*/".
2481 Parens inside single and double quotes are also
2482 counted, causing a string that contains a paren to
2483 disturb the matching. For example, in a line like
2484 "if (strcmp("foo(", s))" the first paren does not
2485 match the last one. When this flag is not included,
2486 parens inside single and double quotes are treated
2487 specially. When matching a paren outside of quotes,
2488 everything inside quotes is ignored. When matching a
2489 paren inside quotes, it will find the matching one (if
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00002490 there is one). This works very well for C programs.
Bram Moolenaar293ee4d2004-12-09 21:34:53 +00002491 This flag is also used for other features, such as
2492 C-indenting.
Bram Moolenaar7c626922005-02-07 22:01:03 +00002493 *cpo--*
2494 - When included, a vertical movement command fails when
Bram Moolenaar8ada17c2006-01-19 22:16:24 +00002495 it would go above the first line or below the last
2496 line. Without it the cursor moves to the first or
2497 last line, unless it already was in that line.
Bram Moolenaar7c626922005-02-07 22:01:03 +00002498 Applies to the commands "-", "k", CTRL-P, "+", "j",
Bram Moolenaar8ada17c2006-01-19 22:16:24 +00002499 CTRL-N, CTRL-J and ":1234".
Bram Moolenaar1cd871b2004-12-19 22:46:22 +00002500 *cpo-+*
2501 + When included, a ":write file" command will reset the
2502 'modified' flag of the buffer, even though the buffer
2503 itself may still be different from its file.
Bram Moolenaarc9b4b052006-04-30 18:54:39 +00002504 *cpo-star*
Bram Moolenaar071d4272004-06-13 20:20:40 +00002505 * Use ":*" in the same way as ":@". When not included,
2506 ":*" is an alias for ":'<,'>", select the Visual area.
2507 *cpo-<*
2508 < Disable the recognition of special key codes in |<>|
2509 form in mappings, abbreviations, and the "to" part of
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00002510 menu commands. For example, the command
Bram Moolenaar071d4272004-06-13 20:20:40 +00002511 ":map X <Tab>" results in X being mapped to:
2512 '<' included: "<Tab>" (5 characters)
2513 '<' excluded: "^I" (^I is a real <Tab>)
2514 Also see the 'k' flag above.
Bram Moolenaar4399ef42005-02-12 14:29:27 +00002515 *cpo->*

2517 the appended text.

2520 and the cursor is right in front of the searched
2521 character, the cursor won't move. When not included,
2522 the cursor would skip over it and jump to the

Christian Brabandtaae58342023-04-23 17:50:22 +01002564 Only use if you need to be backwards compatible.
Bram Moolenaar0bbabe82010-05-17 20:32:55 +02002565 *blowfish*
Bram Moolenaar8f4ac012014-08-10 13:38:34 +02002566 blowfish Blowfish method. Medium strong encryption but it has
2567 an implementation flaw. Requires Vim 7.3 or later,
2568 files can NOT be read by Vim 7.2 and older. This adds
2569 a "seed" to the file, every time you write the file
2570 the encrypted bytes will be different.
Christian Brabandtaae58342023-04-23 17:50:22 +01002571 Obsolete, please do no longer use.
Bram Moolenaar8f4ac012014-08-10 13:38:34 +02002572 *blowfish2*
2573 blowfish2 Blowfish method. Medium strong encryption. Requires
Bram Moolenaar5e9b2fa2016-02-01 22:37:05 +01002574 Vim 7.4.401 or later, files can NOT be read by Vim 7.3
Bram Moolenaar8f4ac012014-08-10 13:38:34 +02002575 and older. This adds a "seed" to the file, every time
2576 you write the file the encrypted bytes will be
2577 different. The whole undo file is encrypted, not just
2578 the pieces of text.
Bram Moolenaara2baa732022-02-04 16:09:54 +00002579 *E1193* *E1194* *E1195* *E1196* *E1230*

2581 xchacha20 XChaCha20 Cipher with Poly1305 Message Authentication
2582 Code. Medium strong till strong encryption.
2583 Encryption is provided by the libsodium library, it
Bram Moolenaar22863042021-10-16 15:23:36 +01002584 requires Vim to be built with |+sodium|.
Christian Brabandtf573c6e2021-06-20 14:02:16 +02002585 It adds a seed and a message authentication code (MAC)
2586 to the file. This needs at least a Vim 8.2.3022 to
2587 read the encrypted file.
2588 Encryption of swap files is not supported, therefore
2589 no swap file will be used when xchacha20 encryption is
2590 enabled.
2591 Encryption of undo files is not yet supported,
2592 therefore no undo file will currently be written.
Christian Brabandtaae58342023-04-23 17:50:22 +01002593 CAREFUL: Files written with this method might have to
2594 be read back with the same version of Vim if the
2595 binary format changes later.
2596 Obsolete, please do no longer use.
2597 xchacha20v2 Same algorithm as with "xchacha20" that correctly
2598 stores the key derivation parameters together with the
2599 encrypted file. Should work better in case the
2600 parameters in the libsodium library ever change.
2601 STILL EXPERIMENTAL: Files written with this method
Christian Brabandtf573c6e2021-06-20 14:02:16 +02002602 might have to be read back with the same version of
2603 Vim if the binary format changes later.
Bram Moolenaarf50a2532010-05-21 15:36:08 +02002604
Christian Brabandtaae58342023-04-23 17:50:22 +01002605 You should use "blowfish2", also to re-encrypt older files. The
2606 "xchacha20" method provides better encryption, but it does not work
2607 with all versions of Vim.
Bram Moolenaar4f3f6682016-03-26 23:01:59 +01002608
Bram Moolenaar40e6a712010-05-16 22:32:54 +02002609 When reading an encrypted file 'cryptmethod' will be set automatically
Bram Moolenaarf50a2532010-05-21 15:36:08 +02002610 to the detected method of the file being read. Thus if you write it
2611 without changing 'cryptmethod' the same method will be used.
2612 Changing 'cryptmethod' does not mark the file as modified, you have to
Bram Moolenaar49771f42010-07-20 17:32:38 +02002613 explicitly write it, you don't get a warning unless there are other
2614 modifications. Also see |:X|.
2615
2616 When setting the global value to an empty string, it will end up with
Bram Moolenaara86187b2018-12-16 18:20:00 +01002617 the value "blowfish2". When setting the local value to an empty
2618 string the buffer will use the global value.

Bram Moolenaarf50a2532010-05-21 15:36:08 +02002620 When a new encryption method is added in a later version of Vim, and
2621 the current version does not recognize it, you will get *E821* .
Bram Moolenaar49771f42010-07-20 17:32:38 +02002622 You need to edit this file with the later version of Vim.

Bram Moolenaar57657d82006-04-21 22:12:41 +00002743 These values can be used:
2744 msg Error messages that would otherwise be omitted will be given
2745 anyway.
2746 throw Error messages that would otherwise be omitted will be given
2747 anyway and also throw an exception and set |v:errmsg|.
2748 beep A message will be given when otherwise only a beep would be
2749 produced.
Bram Moolenaar26a60b42005-02-22 08:49:11 +00002750 The values can be combined, separated by a comma.
Bram Moolenaar57657d82006-04-21 22:12:41 +00002751 "msg" and "throw" are useful for debugging 'foldexpr', 'formatexpr' or
2752 'indentexpr'.

2756 global or local to buffer |global-local|
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00002757 Pattern to be used to find a macro definition. It is a search
Bram Moolenaar071d4272004-06-13 20:20:40 +00002758 pattern, just like for the "/" command. This option is used for the
2759 commands like "[i" and "[d" |include-search|. The 'isident' option is
2760 used to recognize the defined name after the match:
2761 {match with 'define'}{non-ID chars}{defined name}{non-ID char}
2762 See |option-backslash| about inserting backslashes to include a space
2763 or backslash.
2764 The default value is for C programs. For C++ this value would be
2765 useful, to include const type declarations: >
2766 ^\(#\s*define\|[a-z]*\s*const\s*[a-z]*\)
Bram Moolenaar63b74a82019-03-24 15:09:13 +01002767< You can also use "\ze" just before the name and continue the pattern
2768 to check what is following. E.g. for Javascript, if a function is
2769 defined with "func_name = function(args)": >
2770 ^\s*\ze\i\+\s*=\s*function(
2771< If the function is defined with "func_name : function() {...": >

Bram Moolenaar071d4272004-06-13 20:20:40 +00002773< When using the ":set" command, you need to double the backslashes!
Bram Moolenaar63b74a82019-03-24 15:09:13 +01002774 To avoid that use `:let` with a single quote string: >
2775 let &l:define = '^\s*\ze\k\+\s*=\s*function('

2782 "x" delete each combining character on its own. When it is off (the
2783 default) the character along with its combining characters are
2784 deleted.
Bram Moolenaar4f4d51a2020-10-11 13:57:40 +02002785 Note: When 'delcombine' is set "xx" may work differently from "2x"!
Bram Moolenaar071d4272004-06-13 20:20:40 +00002786
2787 This is useful for Arabic, Hebrew and many other languages where one
2788 may have combining characters overtop of base characters, and want
2789 to remove only the combining ones.

2796 for keyword completion commands |i_CTRL-X_CTRL-K|. Each file should
2797 contain a list of words. This can be one word per line, or several
2798 words per line, separated by non-keyword characters (white space is
2799 preferred). Maximum line length is 510 bytes.

2801 When this option is empty or an entry "spell" is present, and spell
2802 checking is enabled, words in the word lists for the currently active

2804
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00002805 To include a comma in a file name precede it with a backslash. Spaces
Bram Moolenaar071d4272004-06-13 20:20:40 +00002806 after a comma are ignored, otherwise spaces are included in the file
2807 name. See |option-backslash| about using backslashes.
Bram Moolenaard8b02732005-01-14 21:48:43 +00002808 This has nothing to do with the |Dictionary| variable type.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002809 Where to find a list of words?
2810 - On FreeBSD, there is the file "/usr/share/dict/words".
2811 - In the Simtel archive, look in the "msdos/linguist" directory.
2812 - In "miscfiles" of the GNU collection.
2813 The use of |:set+=| and |:set-=| is preferred when adding or removing
2814 directories from the list. This avoids problems when a future version
2815 uses another default.
2816 Backticks cannot be used in this option for security reasons.

Bram Moolenaarf4b8e572004-06-24 15:53:16 +00002841 Option settings for diff mode. It can consist of the following items.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002842 All are optional. Items must be separated by a comma.
2843
2844 filler Show filler lines, to keep the text
2845 synchronized with a window that has inserted
2846 lines at the same position. Mostly useful
2847 when windows are side-by-side and 'scrollbind'
2848 is set.
2849
2850 context:{n} Use a context of {n} lines between a change
2851 and a fold that contains unchanged lines.
2852 When omitted a context of six lines is used.
Bram Moolenaarf6b40102019-02-22 15:24:03 +01002853 When using zero the context is actually one,
2854 since folds require a line in between, also
dundargoc20f48d52023-10-02 21:49:23 +02002855 for a deleted line. Set it to a very large
2856 value (999999) to disable folding completely.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002857 See |fold-diff|.
2858
Bram Moolenaar95bafa22018-10-02 13:26:25 +02002859 iblank Ignore changes where lines are all blank. Adds
2860 the "-B" flag to the "diff" command if
2861 'diffexpr' is empty. Check the documentation
2862 of the "diff" command for what this does
2863 exactly.
2864 NOTE: the diff windows will get out of sync,
2865 because no differences between blank lines are
2866 taken into account.
2867
Bram Moolenaar071d4272004-06-13 20:20:40 +00002868 icase Ignore changes in case of text. "a" and "A"
2869 are considered the same. Adds the "-i" flag
2870 to the "diff" command if 'diffexpr' is empty.
2871
2872 iwhite Ignore changes in amount of white space. Adds
2873 the "-b" flag to the "diff" command if
2874 'diffexpr' is empty. Check the documentation
2875 of the "diff" command for what this does
2876 exactly. It should ignore adding trailing
2877 white space, but not leading white space.
2878
Bram Moolenaar95bafa22018-10-02 13:26:25 +02002879 iwhiteall Ignore all white space changes. Adds
2880 the "-w" flag to the "diff" command if
2881 'diffexpr' is empty. Check the documentation
2882 of the "diff" command for what this does
2883 exactly.
2884
2885 iwhiteeol Ignore white space changes at end of line.
2886 Adds the "-Z" flag to the "diff" command if
2887 'diffexpr' is empty. Check the documentation
2888 of the "diff" command for what this does
2889 exactly.
2890
Bram Moolenaar7d47b6e2006-03-15 22:59:18 +00002891 horizontal Start diff mode with horizontal splits (unless
2892 explicitly specified otherwise).
2893
2894 vertical Start diff mode with vertical splits (unless
2895 explicitly specified otherwise).
2896
Bram Moolenaarc8234772019-11-10 21:00:27 +01002897 closeoff When a window is closed where 'diff' is set
2898 and there is only one window remaining in the
2899 same tab page with 'diff' set, execute
2900 `:diffoff` in that window. This undoes a
2901 `:diffsplit` command.
2902
Bram Moolenaar97ce4192017-12-01 20:35:58 +01002903 hiddenoff Do not use diff mode for a buffer when it
2904 becomes hidden.
2905
Bram Moolenaar7d47b6e2006-03-15 22:59:18 +00002906 foldcolumn:{n} Set the 'foldcolumn' option to {n} when
2907 starting diff mode. Without this 2 is used.
2908
Bram Moolenaar4223d432021-02-10 13:18:17 +01002909 followwrap Follow the 'wrap' option and leave as it is.
2910
Bram Moolenaare828b762018-09-10 17:51:58 +02002911 internal Use the internal diff library. This is
2912 ignored when 'diffexpr' is set. *E960*
2913 When running out of memory when writing a
2914 buffer this item will be ignored for diffs
2915 involving that buffer. Set the 'verbose'
2916 option to see when this happens.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002917

Bram Moolenaare828b762018-09-10 17:51:58 +02002921
2922 algorithm:{text} Use the specified diff algorithm with the
Bram Moolenaarf0d58ef2018-11-16 16:13:44 +01002923 internal diff engine. Currently supported
Bram Moolenaare828b762018-09-10 17:51:58 +02002924 algorithms are:

2950 global
2951 List of directory names for the swap file, separated with commas.
Bram Moolenaare7b1ea02020-08-07 19:54:59 +02002952 Recommended value: ".,~/vimswap//" - this will put the swap file next
2953 to the edited file if possible, and in your personal swap directory
2954 otherwise. Make sure "~/vimswap//" is only readable for you.
2955
2956 Possible items:
Bram Moolenaar071d4272004-06-13 20:20:40 +00002957 - The swap file will be created in the first directory where this is
2958 possible.
2959 - Empty means that no swap file will be used (recovery is
Bram Moolenaar00e192b2019-10-19 17:01:28 +02002960 impossible!) and no |E303| error will be given.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002961 - A directory "." means to put the swap file in the same directory as
2962 the edited file. On Unix, a dot is prepended to the file name, so
2963 it doesn't show in a directory listing. On MS-Windows the "hidden"
2964 attribute is set and a dot prepended if possible.
Bram Moolenaar8024f932020-01-14 19:29:13 +01002965 - A directory starting with "./" (or ".\" for MS-Windows) means to put
2966 the swap file relative to where the edited file is. The leading "."
2967 is replaced with the path name of the edited file.
Bram Moolenaarb782ba42018-08-07 21:39:28 +02002968 - For Unix and Win32, if a directory ends in two path separators "//",
2969 the swap file name will be built from the complete path to the file
Bram Moolenaar207f0092020-08-30 17:20:20 +02002970 with all path separators replaced by percent '%' signs (including
2971 the colon following the drive letter on Win32). This will ensure
2972 file name uniqueness in the preserve directory.
Bram Moolenaarb782ba42018-08-07 21:39:28 +02002973 On Win32, it is also possible to end with "\\". However, When a
2974 separating comma is following, you must use "//", since "\\" will
2975 include the comma in the file name. Therefore it is recommended to
2976 use '//', instead of '\\'.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002977 - Spaces after the comma are ignored, other spaces are considered part
2978 of the directory name. To have a space at the start of a directory
2979 name, precede it with a backslash.
2980 - To include a comma in a directory name precede it with a backslash.
2981 - A directory name may end in an ':' or '/'.
2982 - Environment variables are expanded |:set_env|.
2983 - Careful with '\' characters, type one before a space, type two to
2984 get one in the option (see |option-backslash|), for example: >
2985 :set dir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
2986< - For backwards compatibility with Vim version 3.0 a '>' at the start
2987 of the option is removed.
2988 Using "." first in the list is recommended. This means that editing
2989 the same file twice will result in a warning. Using "/tmp" on Unix is
2990 discouraged: When the system crashes you lose the swap file.
2991 "/var/tmp" is often not cleared when rebooting, thus is a better
Bram Moolenaare7b1ea02020-08-07 19:54:59 +02002992 choice than "/tmp". But others on the computer may be able to see the
2993 files, and it can contain a lot of files, your swap files get lost in
2994 the crowd. That is why a "tmp" directory in your home directory is
2995 tried first.
Bram Moolenaar071d4272004-06-13 20:20:40 +00002996 The use of |:set+=| and |:set-=| is preferred when adding or removing
2997 directories from the list. This avoids problems when a future version
2998 uses another default.
2999 This option cannot be set from a |modeline| or in the |sandbox|, for
3000 security reasons.

3011 rest of the line is not displayed.
3012 truncate Like "lastline", but "@@@" is displayed in the first

3042 global
Bram Moolenaar3848e002016-03-19 18:42:29 +01003043 When on all Unicode emoji characters are considered to be full width.
Bram Moolenaar1d59aa12020-09-19 18:50:13 +02003044 This excludes "text emoji" characters, which are normally displayed as
3045 single width. Unfortunately there is no good specification for this
3046 and it has been determined on trial-and-error basis. Use the
3047 |setcellwidths()| function to change the behavior.

K.Takataf883d902021-05-30 18:04:19 +02003050'encoding' 'enc' string (default for MS-Windows: "utf-8",

Bram Moolenaar071d4272004-06-13 20:20:40 +00003052 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00003053 Sets the character encoding used inside Vim. It applies to text in
3054 the buffers, registers, Strings in expressions, text stored in the
3055 viminfo file, etc. It sets the kind of characters which Vim can work
3056 with. See |encoding-names| for the possible values.
3057
3058 NOTE: Changing this option will not change the encoding of the
Bram Moolenaar1cd871b2004-12-19 22:46:22 +00003059 existing text in Vim. It may cause non-ASCII text to become invalid.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003060 It should normally be kept at its default value, or set when Vim
Bram Moolenaar02467872007-05-06 13:22:01 +00003061 starts up. See |multibyte|. To reload the menus see |:menutrans|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003062
Bram Moolenaar865242e2010-07-14 21:12:05 +02003063 This option cannot be set from a |modeline|. It would most likely
3064 corrupt the text.
3065
Bram Moolenaar3df01732017-02-17 22:47:16 +01003066 NOTE: For GTK+ 2 or later, it is highly recommended to set 'encoding'
3067 to "utf-8". Although care has been taken to allow different values of
Bram Moolenaar071d4272004-06-13 20:20:40 +00003068 'encoding', "utf-8" is the natural choice for the environment and
3069 avoids unnecessary conversion overhead. "utf-8" has not been made
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00003070 the default to prevent different behavior of the GUI and terminal
Bram Moolenaar071d4272004-06-13 20:20:40 +00003071 versions, and to avoid changing the encoding of newly created files
3072 without your knowledge (in case 'fileencodings' is empty).
3073
3074 The character encoding of files can be different from 'encoding'.
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00003075 This is specified with 'fileencoding'. The conversion is done with
Bram Moolenaar071d4272004-06-13 20:20:40 +00003076 iconv() or as specified with 'charconvert'.
3077
Bram Moolenaar207f0092020-08-30 17:20:20 +02003078 If you need to know whether 'encoding' is a multibyte encoding, you
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01003079 can use: >
3080 if has("multi_byte_encoding")
3081<
Bram Moolenaar071d4272004-06-13 20:20:40 +00003082 Normally 'encoding' will be equal to your current locale. This will
3083 be the default if Vim recognizes your environment settings. If
3084 'encoding' is not set to the current locale, 'termencoding' must be
3085 set to convert typed and displayed text. See |encoding-table|.
3086
3087 When you set this option, it fires the |EncodingChanged| autocommand
3088 event so that you can set up fonts if necessary.
3089
3090 When the option is set, the value is converted to lowercase. Thus
3091 you can set it with uppercase values too. Underscores are translated
3092 to '-' signs.
3093 When the encoding is recognized, it is changed to the standard name.
3094 For example "Latin-1" becomes "latin1", "ISO_88592" becomes
3095 "iso-8859-2" and "utf8" becomes "utf-8".
3096
3097 Note: "latin1" is also used when the encoding could not be detected.
3098 This only works when editing files in the same encoding! When the
3099 actual character set is not latin1, make sure 'fileencoding' and
3100 'fileencodings' are empty. When conversion is needed, switch to using
3101 utf-8.
3102
3103 When "unicode", "ucs-2" or "ucs-4" is used, Vim internally uses utf-8.
3104 You don't notice this while editing, but it does matter for the
3105 |viminfo-file|. And Vim expects the terminal to use utf-8 too. Thus
3106 setting 'encoding' to one of these values instead of utf-8 only has
3107 effect for encoding used for files when 'fileencoding' is empty.
3108
Bram Moolenaar661b1822005-07-28 22:36:45 +00003109 When 'encoding' is set to a Unicode encoding, and 'fileencodings' was
3110 not set yet, the default for 'fileencodings' is changed.

Bram Moolenaar071d4272004-06-13 20:20:40 +00003117 When writing a file and this option is off and the 'binary' option
Bram Moolenaar6ebe4f92022-10-28 20:47:54 +01003118 is on, or 'fixeol' option is off, no CTRL-Z will be written at the

3127 last line in the file. This option is automatically set or reset when
3128 starting to edit a new file, depending on whether file has an <EOL>
3129 for the last line in the file. Normally you don't have to set or
3130 reset this option.
3131 When 'binary' is off and 'fixeol' is on the value is not used when
3132 writing the file. When 'binary' is on or 'fixeol' is off it is used
3133 to remember the presence of a <EOL> for the last line in the file, so
3134 that when you write the file the situation from the original file can
3135 be kept. But you can change it if you want to.

3140 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00003141 When on, all the windows are automatically made the same size after
Bram Moolenaar009b2592004-10-24 19:18:58 +00003142 splitting or closing a window. This also happens the moment the
3143 option is switched on. When off, splitting a window will reduce the
3144 size of the current window and leave the other windows the same. When
3145 closing a window the extra lines are given to the window next to it
3146 (depending on 'splitbelow' and 'splitright').
Bram Moolenaar071d4272004-06-13 20:20:40 +00003147 When mixing vertically and horizontally split windows, a minimal size
3148 is computed and some windows may be larger if there is room. The
3149 'eadirection' option tells in which direction the size is affected.
Bram Moolenaar67f71312007-08-12 14:55:56 +00003150 Changing the height and width of a window can be avoided by setting
3151 'winfixheight' and 'winfixwidth', respectively.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01003152 If a window size is specified when creating a new window sizes are
3153 currently not equalized (it's complicated, but may be implemented in

3206 used in Insert mode if they start with an <Esc>. The advantage of
3207 this is that the single <Esc> is recognized immediately, instead of
3208 after one second. Instead of resetting this option, you might want to
3209 try changing the values for 'timeoutlen' and 'ttimeoutlen'. Note that

Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01003267 Conversion will also be done when 'encoding' and 'fileencoding' are
3268 both a Unicode encoding and 'fileencoding' is not utf-8. That's
3269 because internally Unicode is always stored as utf-8.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003270 WARNING: Conversion can cause loss of information! When
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01003271 'encoding' is "utf-8" or another Unicode encoding, conversion
3272 is most likely done in a way that the reverse conversion
3273 results in the same text. When 'encoding' is not "utf-8" some

Bram Moolenaar071d4272004-06-13 20:20:40 +00003276 See 'encoding' for the possible values. Additionally, values may be

Bram Moolenaar02467872007-05-06 13:22:01 +00003282 'fileencoding', use the |++enc| argument. One exception: when
3283 'fileencodings' is empty the value of 'fileencoding' is used.
Bram Moolenaara23ccb82006-02-27 00:08:02 +00003284 For a new file the global value of 'fileencoding' is used.

Bram Moolenaar071d4272004-06-13 20:20:40 +00003286 Prepending "8bit-" and "2byte-" has no meaning here, they are ignored.
3287 When the option is set, the value is converted to lowercase. Thus
3288 you can set it with uppercase values too. '_' characters are
3289 replaced with '-'. If a name is recognized from the list for
3290 'encoding', it is replaced by the standard name. For example
3291 "ISO8859-2" becomes "iso-8859-2".
Bram Moolenaar865242e2010-07-14 21:12:05 +02003292
Bram Moolenaar071d4272004-06-13 20:20:40 +00003293 When this option is set, after starting to edit a file, the 'modified'
3294 option is set, because the file would be different when written.
Bram Moolenaar865242e2010-07-14 21:12:05 +02003295
3296 Keep in mind that changing 'fenc' from a modeline happens
3297 AFTER the text has been read, thus it applies to when the file will be
3298 written. If you do set 'fenc' in a modeline, you might want to set
3299 'nomodified' to avoid not being able to ":q".

Bram Moolenaar071d4272004-06-13 20:20:40 +00003313 This is a list of character encodings considered when starting to edit
3314 an existing file. When a file is read, Vim tries to use the first
3315 mentioned character encoding. If an error is detected, the next one
3316 in the list is tried. When an encoding is found that works,
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00003317 'fileencoding' is set to it. If all fail, 'fileencoding' is set to
Bram Moolenaar071d4272004-06-13 20:20:40 +00003318 an empty string, which means the value of 'encoding' is used.
3319 WARNING: Conversion can cause loss of information! When
3320 'encoding' is "utf-8" (or one of the other Unicode variants)
3321 conversion is most likely done in a way that the reverse
3322 conversion results in the same text. When 'encoding' is not
Bram Moolenaarc6d8db72005-12-13 20:04:55 +00003323 "utf-8" some non-ASCII characters may be lost! You can use
3324 the |++bad| argument to specify what is done with characters
3325 that can't be converted.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003326 For an empty file or a file with only ASCII characters most encodings
3327 will work and the first entry of 'fileencodings' will be used (except
3328 "ucs-bom", which requires the BOM to be present). If you prefer
3329 another encoding use an BufReadPost autocommand event to test if your
3330 preferred encoding is to be used. Example: >
3331 au BufReadPost * if search('\S', 'w') == 0 |
3332 \ set fenc=iso-2022-jp | endif
3333< This sets 'fileencoding' to "iso-2022-jp" if the file does not contain
3334 non-blank characters.
Bram Moolenaarc6d8db72005-12-13 20:04:55 +00003335 When the |++enc| argument is used then the value of 'fileencodings' is
3336 not used.
Bram Moolenaara23ccb82006-02-27 00:08:02 +00003337 Note that 'fileencodings' is not used for a new file, the global value
3338 of 'fileencoding' is used instead. You can set it with: >
3339 :setglobal fenc=iso-8859-2
3340< This means that a non-existing file may get a different encoding than
3341 an empty file.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003342 The special value "ucs-bom" can be used to check for a Unicode BOM
3343 (Byte Order Mark) at the start of the file. It must not be preceded
3344 by "utf-8" or another Unicode encoding for this to work properly.
3345 An entry for an 8-bit encoding (e.g., "latin1") should be the last,
3346 because Vim cannot detect an error, thus the encoding is always
3347 accepted.
Bram Moolenaar1cd871b2004-12-19 22:46:22 +00003348 The special value "default" can be used for the encoding from the
K.Takataef8706f2021-05-31 18:40:49 +02003349 environment. On MS-Windows this is the system encoding. Otherwise
3350 this is the default value for 'encoding'. It is useful when
3351 'encoding' is set to "utf-8" and your environment uses a non-latin1
3352 encoding, such as Russian.
Bram Moolenaarca003e12006-03-17 23:19:38 +00003353 When 'encoding' is "utf-8" and a file contains an illegal byte
3354 sequence it won't be recognized as UTF-8. You can use the |8g8|
3355 command to find the illegal byte sequence.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003356 WRONG VALUES: WHAT'S WRONG:
3357 latin1,utf-8 "latin1" will always be used
3358 utf-8,ucs-bom,latin1 BOM won't be recognized in an utf-8
3359 file
3360 cp1250,latin1 "cp1250" will always be used
3361 If 'fileencodings' is empty, 'fileencoding' is not modified.
3362 See 'fileencoding' for the possible values.
3363 Setting this option does not have an effect until the next time a file
3364 is read.

3366 *'fileformat'* *'ff'*
Bram Moolenaar00590742019-02-15 21:06:09 +01003367'fileformat' 'ff' string (MS-Windows default: "dos",
3368 Unix, macOS default: "unix")
Bram Moolenaar071d4272004-06-13 20:20:40 +00003369 local to buffer
Bram Moolenaar071d4272004-06-13 20:20:40 +00003370 This gives the <EOL> of the current buffer, which is used for
3371 reading/writing the buffer from/to a file:
Bram Moolenaar4072ba52020-12-23 13:56:35 +01003372 dos <CR><NL>
Bram Moolenaar071d4272004-06-13 20:20:40 +00003373 unix <NL>
3374 mac <CR>
3375 When "dos" is used, CTRL-Z at the end of a file is ignored.
3376 See |file-formats| and |file-read|.
3377 For the character encoding of the file see 'fileencoding'.
3378 When 'binary' is set, the value of 'fileformat' is ignored, file I/O
Bram Moolenaarbf884932013-04-05 22:26:15 +02003379 works like it was set to "unix".
Bram Moolenaar071d4272004-06-13 20:20:40 +00003380 This option is set automatically when starting to edit a file and
3381 'fileformats' is not empty and 'binary' is off.
3382 When this option is set, after starting to edit a file, the 'modified'
3383 option is set, because the file would be different when written.
3384 This option can not be changed when 'modifiable' is off.
3385 For backwards compatibility: When this option is set to "dos",
3386 'textmode' is set, otherwise 'textmode' is reset.
3387
3388 *'fileformats'* *'ffs'*
3389'fileformats' 'ffs' string (default:

3394 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00003395 This gives the end-of-line (<EOL>) formats that will be tried when
3396 starting to edit a new buffer and when reading a file into an existing
3397 buffer:
3398 - When empty, the format defined with 'fileformat' will be used
3399 always. It is not set automatically.
3400 - When set to one name, that format will be used whenever a new buffer
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00003401 is opened. 'fileformat' is set accordingly for that buffer. The
Bram Moolenaar071d4272004-06-13 20:20:40 +00003402 'fileformats' name will be used when a file is read into an existing
3403 buffer, no matter what 'fileformat' for that buffer is set to.
3404 - When more than one name is present, separated by commas, automatic
3405 <EOL> detection will be done when reading a file. When starting to
3406 edit a file, a check is done for the <EOL>:
3407 1. If all lines end in <CR><NL>, and 'fileformats' includes "dos",
3408 'fileformat' is set to "dos".
3409 2. If a <NL> is found and 'fileformats' includes "unix", 'fileformat'
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00003410 is set to "unix". Note that when a <NL> is found without a
Bram Moolenaar071d4272004-06-13 20:20:40 +00003411 preceding <CR>, "unix" is preferred over "dos".
Bram Moolenaar2b8388b2015-02-28 13:11:45 +01003412 3. If 'fileformat' has not yet been set, and if a <CR> is found, and
3413 if 'fileformats' includes "mac", 'fileformat' is set to "mac".
Bram Moolenaar00659062010-09-21 22:34:02 +02003414 This means that "mac" is only chosen when:
3415 "unix" is not present or no <NL> is found in the file, and
3416 "dos" is not present or no <CR><NL> is found in the file.
3417 Except: if "unix" was chosen, but there is a <CR> before
3418 the first <NL>, and there appear to be more <CR>s than <NL>s in
Bram Moolenaar166af9b2010-11-16 20:34:40 +01003419 the first few lines, "mac" is used.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003420 4. If 'fileformat' is still not set, the first name from
3421 'fileformats' is used.
3422 When reading a file into an existing buffer, the same is done, but
3423 this happens like 'fileformat' has been set appropriately for that
3424 file only, the option is not changed.
3425 When 'binary' is set, the value of 'fileformats' is not used.
3426
Bram Moolenaar4f3f6682016-03-26 23:01:59 +01003427 When Vim starts up with an empty buffer the first item is used. You
3428 can overrule this by setting 'fileformat' in your .vimrc.
Bram Moolenaar81af9252010-12-10 20:35:50 +01003429
Bram Moolenaar071d4272004-06-13 20:20:40 +00003430 For systems with a Dos-like <EOL> (<CR><NL>), when reading files that
3431 are ":source"ed and for vimrc files, automatic <EOL> detection may be
3432 done:
3433 - When 'fileformats' is empty, there is no automatic detection. Dos
3434 format will be used.
3435 - When 'fileformats' is set to one or more names, automatic detection
3436 is done. This is based on the first <NL> in the file: If there is a
3437 <CR> in front of it, Dos format is used, otherwise Unix format is
3438 used.
3439 Also see |file-formats|.
3440 For backwards compatibility: When this option is set to an empty
3441 string or one format (no comma is included), 'textauto' is reset,
3442 otherwise 'textauto' is set.
3443 NOTE: This option is set to the Vi default value when 'compatible' is
3444 set and to the Vim default value when 'compatible' is reset.

Bram Moolenaarbf884932013-04-05 22:26:15 +02003446 *'fileignorecase'* *'fic'* *'nofileignorecase'* *'nofic'*
3447'fileignorecase' 'fic' boolean (default on for systems where case in file
3448 names is normally ignored)
Bram Moolenaar71afbfe2013-03-19 16:49:16 +01003449 global
Bram Moolenaar71afbfe2013-03-19 16:49:16 +01003450 When set case is ignored when using file names and directories.
3451 See 'wildignorecase' for only ignoring case when doing completion.
3452
Bram Moolenaar071d4272004-06-13 20:20:40 +00003453 *'filetype'* *'ft'*

Bram Moolenaar071d4272004-06-13 20:20:40 +00003456 When this option is set, the FileType autocommand event is triggered.
3457 All autocommands that match with the value of this option will be
3458 executed. Thus the value of 'filetype' is used in place of the file
3459 name.
3460 Otherwise this option does not always reflect the current file type.
3461 This option is normally set when the file type is detected. To enable
3462 this use the ":filetype on" command. |:filetype|
3463 Setting this option to a different value is most useful in a modeline,
3464 for a file for which the file type is not automatically recognized.
Bram Moolenaar97b2ad32006-03-18 21:40:56 +00003465 Example, for in an IDL file:
3466 /* vim: set filetype=idl : */ ~
3467 |FileType| |filetypes|
3468 When a dot appears in the value then this separates two filetype
3469 names. Example:
3470 /* vim: set filetype=c.doxygen : */ ~
3471 This will use the "c" filetype first, then the "doxygen" filetype.
3472 This works both for filetype plugins and for syntax files. More than
3473 one dot may appear.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003474 This option is not copied to another buffer, independent of the 's' or
3475 'S' flag in 'cpoptions'.

3591 Used only when 'foldmethod' is "indent". Lines starting with
3592 characters in 'foldignore' will get their fold level from surrounding
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00003593 lines. White space is skipped before checking for this character.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003594 The default "#" works well for C programs. See |fold-indent|.

3601 Sets the fold level: Folds with a higher level will be closed.
3602 Setting this option to zero will close all folds. Higher numbers will
3603 close fewer folds.
3604 This option is set by commands like |zm|, |zM| and |zR|.
3605 See |fold-foldlevel|.

3611 feature}
3612 Sets 'foldlevel' when starting to edit another buffer in a window.
3613 Useful to always start editing with all folds closed (value zero),
3614 some folds closed (one) or no folds closed (99).
3615 This is done before reading any modeline, thus a setting in a modeline
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00003616 overrules this option. Starting to edit a file for |diff-mode| also
Bram Moolenaar071d4272004-06-13 20:20:40 +00003617 ignores this option and closes all folds.
3618 It is also done before BufReadPre autocommands, to allow an autocmd to
3619 overrule the 'foldlevel' value for specific files.
3620 When the value is negative, it is not used.
3621
3622 *'foldmarker'* *'fmr'* *E536*
3623'foldmarker' 'fmr' string (default: "{{{,}}}")

Bram Moolenaar071d4272004-06-13 20:20:40 +00003625 {not available when compiled without the |+folding|
3626 feature}
3627 The start and end marker used when 'foldmethod' is "marker". There
3628 must be one comma, which separates the start and end marker. The
3629 marker is a literal string (a regular expression would be too slow).
3630 See |fold-marker|.
3631
3632 *'foldmethod'* *'fdm'*
3633'foldmethod' 'fdm' string (default: "manual")

Bram Moolenaar071d4272004-06-13 20:20:40 +00003635 {not available when compiled without the |+folding|

3637 The kind of folding used for the current window. Possible values:
3638 |fold-manual| manual Folds are created manually.
3639 |fold-indent| indent Lines with equal indent form a fold.
3640 |fold-expr| expr 'foldexpr' gives the fold level of a line.
3641 |fold-marker| marker Markers are used to specify folds.
3642 |fold-syntax| syntax Syntax highlighting items specify folds.
3643 |fold-diff| diff Fold text that is not changed.

Bram Moolenaar00654022011-02-25 14:42:19 +01003650 Sets the number of screen lines above which a fold can be displayed
3651 closed. Also for manually closed folds. With the default value of
3652 one a fold can only be closed if it takes up two or more screen lines.
3653 Set to zero to be able to close folds of just one screen line.
Bram Moolenaar446beb42011-05-10 17:18:44 +02003654 Note that this only has an effect on what is displayed. After using
Bram Moolenaar071d4272004-06-13 20:20:40 +00003655 "zc" to close a fold, which is displayed open because it's smaller
3656 than 'foldminlines', a following "zc" may close a containing fold.

3659'foldnestmax' 'fdn' number (default: 20)

3663 Sets the maximum nesting of folds for the "indent" and "syntax"
3664 methods. This avoids that too many folds will be created. Using more
3665 than 20 doesn't work, because the internal limit is 20.
3666

3673 Specifies for which type of commands folds will be opened, if the
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01003674 command moves the cursor into a closed fold. It is a comma-separated
Bram Moolenaar071d4272004-06-13 20:20:40 +00003675 list of items.
Bram Moolenaar05365702010-10-27 18:34:44 +02003676 NOTE: When the command is part of a mapping this option is not used.
3677 Add the |zv| command to the mapping to get the same effect.
3678 (rationale: the mapping may want to control opening folds itself)
3679
Bram Moolenaar071d4272004-06-13 20:20:40 +00003680 item commands ~
3681 all any
3682 block "(", "{", "[[", "[{", etc.
3683 hor horizontal movements: "l", "w", "fx", etc.
3684 insert any command in Insert mode

3686 mark jumping to a mark: "'m", CTRL-O, etc.
3687 percent "%"
3688 quickfix ":cn", ":crew", ":make", etc.
3689 search search for a pattern: "/", "n", "*", "gd", etc.
3690 (not for a search pattern in a ":" command)
Bram Moolenaar910f66f2006-04-05 20:41:53 +00003691 Also for |[s| and |]s|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003692 tag jumping to a tag: ":ta", CTRL-T, etc.
3693 undo undo or redo: "u" and CTRL-R
Bram Moolenaar071d4272004-06-13 20:20:40 +00003694 When a movement command is used for an operator (e.g., "dl" or "y%")
3695 this option is not used. This means the operator will include the
3696 whole closed fold.
3697 Note that vertical movements are not here, because it would make it
3698 very difficult to move onto a closed fold.
3699 In insert mode the folds containing the cursor will always be open
3700 when text is inserted.
3701 To close folds you can re-apply 'foldlevel' with the |zx| command or
3702 set the 'foldclose' option to "all".

3709 An expression which is used to specify the text displayed for a closed
Bram Moolenaar6f4754b2022-01-23 12:07:04 +00003710 fold. The context is set to the script where 'foldexpr' was set,
3711 script-local items can be accessed. See |fold-foldtext| for the
3712 usage.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003713
Bram Moolenaar30b65812012-07-12 22:01:11 +02003714 The expression will be evaluated in the |sandbox| if set from a
3715 modeline, see |sandbox-option|.
Bram Moolenaar110289e2019-05-23 15:38:06 +02003716 This option cannot be set in a modeline when 'modelineexpr' is off.
Bram Moolenaarb71eaae2006-01-20 23:10:18 +00003717
3718 It is not allowed to change text or jump to another window while
3719 evaluating 'foldtext' |textlock|.

Bram Moolenaarc95a3022016-06-12 23:01:46 +02003724 {not available when compiled without the |+eval|
3725 feature}
3726 Expression which is evaluated to format a range of lines for the |gq|
3727 operator or automatic formatting (see 'formatoptions'). When this
3728 option is empty 'formatprg' is used.
3729
3730 The |v:lnum| variable holds the first line to be formatted.
3731 The |v:count| variable holds the number of lines to be formatted.
3732 The |v:char| variable holds the character that is going to be
3733 inserted if the expression is being evaluated due to
3734 automatic formatting. This can be empty. Don't insert
3735 it yet!
3736
3737 Example: >
3738 :set formatexpr=mylang#Format()
3739< This will invoke the mylang#Format() function in the
3740 autoload/mylang.vim file in 'runtimepath'. |autoload|
3741
Bram Moolenaara4e0b972022-10-01 19:43:52 +01003742 The advantage of using a function call without arguments is that it is
3743 faster, see |expr-option-function|.
3744
Bram Moolenaarc95a3022016-06-12 23:01:46 +02003745 The expression is also evaluated when 'textwidth' is set and adding
3746 text beyond that limit. This happens under the same conditions as
3747 when internal formatting is used. Make sure the cursor is kept in the
3748 same spot relative to the text then! The |mode()| function will
3749 return "i" or "R" in this situation.
Bram Moolenaar22f1d0e2018-02-27 14:53:30 +01003750
Bram Moolenaarc95a3022016-06-12 23:01:46 +02003751 When the expression evaluates to non-zero Vim will fall back to using
3752 the internal format mechanism.
3753
Yegappan Lakshmanan8bb65f22021-12-26 10:51:39 +00003754 If the expression starts with s: or |<SID>|, then it is replaced with
3755 the script ID (|local-function|). Example: >
3756 set formatexpr=s:MyFormatExpr()
3757 set formatexpr=<SID>SomeFormatExpr()
Bram Moolenaar6f4754b2022-01-23 12:07:04 +00003758< Otherwise, the expression is evaluated in the context of the script
3759 where the option was set, thus script-local items are available.
3760
Bram Moolenaarc95a3022016-06-12 23:01:46 +02003761 The expression will be evaluated in the |sandbox| when set from a
3762 modeline, see |sandbox-option|. That stops the option from working,
3763 since changing the buffer text is not allowed.
Bram Moolenaar110289e2019-05-23 15:38:06 +02003764 This option cannot be set in a modeline when 'modelineexpr' is off.
Bram Moolenaar036986f2017-03-16 17:41:02 +01003765 NOTE: This option is set to "" when 'compatible' is set.

3769 local to buffer
Bram Moolenaar86b68352004-12-27 21:59:20 +00003770 A pattern that is used to recognize a list header. This is used for
3771 the "n" flag in 'formatoptions'.
3772 The pattern must match exactly the text that will be the indent for
Bram Moolenaar677ee682005-01-27 14:41:15 +00003773 the line below it. You can use |/\ze| to mark the end of the match
Bram Moolenaar86b68352004-12-27 21:59:20 +00003774 while still checking more characters. There must be a character
3775 following the pattern, when it matches the whole line it is handled
3776 like there is no match.
3777 The default recognizes a number, followed by an optional punctuation
3778 character and white space.

3785 See |fo-table| for possible values and |gq| for how to format text.
3786 When the 'paste' option is on, no formatting is done (like
3787 'formatoptions' is empty). Commas can be inserted for readability.
Bram Moolenaar6c60f472019-04-28 16:00:35 +02003788 To avoid problems with flags that are added in the future, use the
3789 "+=" and "-=" feature of ":set" |add-option-flags|.

Bram Moolenaara5792f52005-11-23 21:25:05 +00003799 such a program.
Bram Moolenaar1d2ba7f2006-02-14 22:29:30 +00003800 If the 'formatexpr' option is not empty it will be used instead.
3801 Otherwise, if 'formatprg' option is an empty string, the internal

3812 file. This will flush a file to disk, ensuring that it is safely
3813 written even on filesystems which do metadata-only journaling. This
3814 will force the harddrive to spin up on Linux systems running in laptop
3815 mode, so it may be undesirable in some situations. Be warned that
3816 turning this off increases the chances of data loss after a crash. On
3817 systems without an fsync() implementation, this variable is always
3818 off.
3819 Also see 'swapsync' for controlling fsync() on swap files.
Bram Moolenaar340dd0f2021-10-14 17:52:23 +01003820 'fsync' also applies to |writefile()| (unless a flag is used to

Bram Moolenaar8024f932020-01-14 19:29:13 +01003890 modes. It fully works in the GUI. In a Win32 console, only the
Bram Moolenaar5666fcd2019-12-26 14:35:26 +01003891 height of the cursor can be changed. This can be done by specifying a
3892 block cursor, or a percentage for a vertical or horizontal cursor.
Bram Moolenaar1e7813a2015-03-31 18:31:03 +02003893 For a console the 't_SI', 't_SR', and 't_EI' escape sequences are
3894 used.
Bram Moolenaar071d4272004-06-13 20:20:40 +00003895
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01003896 The option is a comma-separated list of parts. Each part consist of a
Bram Moolenaar071d4272004-06-13 20:20:40 +00003897 mode-list and an argument-list:
3898 mode-list:argument-list,mode-list:argument-list,..
3899 The mode-list is a dash separated list of these modes:
3900 n Normal mode
3901 v Visual mode
3902 ve Visual mode with 'selection' "exclusive" (same as 'v',
3903 if not specified)
3904 o Operator-pending mode
3905 i Insert mode
3906 r Replace mode
3907 c Command-line Normal (append) mode
3908 ci Command-line Insert mode
3909 cr Command-line Replace mode
3910 sm showmatch in Insert mode
3911 a all modes
3912 The argument-list is a dash separated list of these arguments:
3913 hor{N} horizontal bar, {N} percent of the character height
3914 ver{N} vertical bar, {N} percent of the character width
3915 block block cursor, fills the whole character
3916 [only one of the above three should be present]
3917 blinkwait{N} *cursor-blinking*
3918 blinkon{N}
3919 blinkoff{N}
3920 blink times for cursor: blinkwait is the delay before
3921 the cursor starts blinking, blinkon is the time that
3922 the cursor is shown and blinkoff is the time that the
3923 cursor is not shown. The times are in msec. When one
3924 of the numbers is zero, there is no blinking. The
3925 default is: "blinkwait700-blinkon400-blinkoff250".
3926 These numbers are used for a missing entry. This
3927 means that blinking is enabled by default. To switch
3928 blinking off you can use "blinkon0". The cursor only
3929 blinks when Vim is waiting for input, not while
3930 executing a command.
3931 To make the cursor blink in an xterm, see
3932 |xterm-blink|.
3933 {group-name}
3934 a highlight group name, that sets the color and font
3935 for the cursor
3936 {group-name}/{group-name}
3937 Two highlight group names, the first is used when
3938 no language mappings are used, the other when they
3939 are. |language-mapping|
3940
3941 Examples of parts:
3942 n-c-v:block-nCursor in Normal, Command-line and Visual mode, use a
3943 block cursor with colors from the "nCursor"
3944 highlight group
3945 i-ci:ver30-iCursor-blinkwait300-blinkon200-blinkoff150
3946 In Insert and Command-line Insert mode, use a
3947 30% vertical bar cursor with colors from the
3948 "iCursor" highlight group. Blink a bit
3949 faster.
3950
3951 The 'a' mode is different. It will set the given argument-list for
3952 all modes. It does not reset anything to defaults. This can be used
3953 to do a common setting for all modes. For example, to switch off
3954 blinking: "a:blinkon0"

Bram Moolenaared203462004-06-16 11:19:22 +00004019 This option only has an effect in the GUI version of Vim. It is a
Bram Moolenaar071d4272004-06-13 20:20:40 +00004020 sequence of letters which describes what components and options of the
4021 GUI should be used.
4022 To avoid problems with flags that are added in the future, use the
4023 "+=" and "-=" feature of ":set" |add-option-flags|.
4024
Bram Moolenaar13568252018-03-16 20:46:58 +01004025 Valid characters are as follows:
4026 *'go-!'*
4027 '!' External commands are executed in a terminal window. Without
4028 this flag the MS-Windows GUI will open a console window to
4029 execute the command. The Unix GUI will simulate a dumb
4030 terminal to list the command output.
4031 The terminal window will be positioned at the bottom, and grow
4032 upwards as needed.
Bram Moolenaarba3ff532018-11-04 14:45:49 +01004033 *'go-a'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004034 'a' Autoselect: If present, then whenever VISUAL mode is started,
4035 or the Visual area extended, Vim tries to become the owner of
4036 the windowing system's global selection. This means that the
4037 Visually highlighted text is available for pasting into other
4038 applications as well as into Vim itself. When the Visual mode
4039 ends, possibly due to an operation on the text, or when an
4040 application wants to paste the selection, the highlighted text
4041 is automatically yanked into the "* selection register.
4042 Thus the selection is still available for pasting into other
4043 applications after the VISUAL mode has ended.
4044 If not present, then Vim won't become the owner of the
4045 windowing system's global selection unless explicitly told to
4046 by a yank or delete operation for the "* register.
4047 The same applies to the modeless selection.
Bram Moolenaarc0885aa2012-07-10 16:49:23 +02004048 *'go-P'*
4049 'P' Like autoselect but using the "+ register instead of the "*
Bram Moolenaar3848e002016-03-19 18:42:29 +01004050 register.
Bram Moolenaar02467872007-05-06 13:22:01 +00004051 *'go-A'*
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00004052 'A' Autoselect for the modeless selection. Like 'a', but only
Bram Moolenaar071d4272004-06-13 20:20:40 +00004053 applies to the modeless selection.

4062
Bram Moolenaar02467872007-05-06 13:22:01 +00004063 *'go-c'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004064 'c' Use console dialogs instead of popup dialogs for simple
4065 choices.
Bram Moolenaar50bf7ce2019-09-15 13:17:00 +02004066 *'go-d'*
4067 'd' Use dark theme variant if available. Currently only works for
4068 GTK+ GUI.
Bram Moolenaar02467872007-05-06 13:22:01 +00004069 *'go-e'*
Bram Moolenaare224ffa2006-03-01 00:01:28 +00004070 'e' Add tab pages when indicated with 'showtabline'.
Bram Moolenaar5c8837f2006-02-25 21:52:33 +00004071 'guitablabel' can be used to change the text in the labels.
4072 When 'e' is missing a non-GUI tab pages line may be used.
Bram Moolenaard68071d2006-05-02 22:08:30 +00004073 The GUI tabs are only supported on some systems, currently
Bram Moolenaarb3f74062020-02-26 16:16:53 +01004074 GTK, Motif, Mac OS/X, Haiku, and MS-Windows.
Bram Moolenaar02467872007-05-06 13:22:01 +00004075 *'go-f'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004076 'f' Foreground: Don't use fork() to detach the GUI from the shell
4077 where it was started. Use this for programs that wait for the
4078 editor to finish (e.g., an e-mail program). Alternatively you
4079 can use "gvim -f" or ":gui -f" to start the GUI in the
4080 foreground. |gui-fork|
4081 Note: Set this option in the vimrc file. The forking may have
Bram Moolenaar910f66f2006-04-05 20:41:53 +00004082 happened already when the |gvimrc| file is read.
Bram Moolenaar02467872007-05-06 13:22:01 +00004083 *'go-i'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004084 'i' Use a Vim icon. For GTK with KDE it is used in the left-upper
4085 corner of the window. It's black&white on non-GTK, because of
4086 limitations of X11. For a color icon, see |X11-icon|.
Bram Moolenaar0bc380a2010-07-10 13:52:13 +02004087 *'go-m'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004088 'm' Menu bar is present.

Bram Moolenaarf4b8e572004-06-24 15:53:16 +00004090 'M' The system menu "$VIMRUNTIME/menu.vim" is not sourced. Note
Bram Moolenaar071d4272004-06-13 20:20:40 +00004091 that this flag must be added in the .vimrc file, before
Bram Moolenaar910f66f2006-04-05 20:41:53 +00004092 switching on syntax or filetype recognition (when the |gvimrc|
Bram Moolenaar071d4272004-06-13 20:20:40 +00004093 file is sourced the system menu has already been loaded; the
Bram Moolenaar01164a62017-11-02 22:58:42 +01004094 `:syntax on` and `:filetype on` commands load the menu too).

Bram Moolenaar071d4272004-06-13 20:20:40 +00004096 'g' Grey menu items: Make menu items that are not active grey. If
4097 'g' is not included inactive menu items are not shown at all.

Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01004102 'T' Include Toolbar. Currently only in Win32, GTK+, Motif and
4103 Photon GUIs.
Bram Moolenaar02467872007-05-06 13:22:01 +00004104 *'go-r'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004105 'r' Right-hand scrollbar is always present.

Bram Moolenaar071d4272004-06-13 20:20:40 +00004112 'L' Left-hand scrollbar is present when there is a vertically
4113 split window.
Bram Moolenaar02467872007-05-06 13:22:01 +00004114 *'go-b'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004115 'b' Bottom (horizontal) scrollbar is present. Its size depends on
4116 the longest visible line, or on the cursor line if the 'h'
4117 flag is included. |gui-horiz-scroll|
Bram Moolenaar0bc380a2010-07-10 13:52:13 +02004118 *'go-h'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004119 'h' Limit horizontal scrollbar size to the length of the cursor
4120 line. Reduces computations. |gui-horiz-scroll|
4121
4122 And yes, you may even have scrollbars on the left AND the right if
4123 you really want to :-). See |gui-scrollbars| for more information.
4124
Bram Moolenaar0bc380a2010-07-10 13:52:13 +02004125 *'go-v'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004126 'v' Use a vertical button layout for dialogs. When not included,
4127 a horizontal layout is preferred, but when it doesn't fit a
Bram Moolenaardad44732021-03-31 20:07:33 +02004128 vertical layout is used anyway. Not supported in GTK 3.
Bram Moolenaar0bc380a2010-07-10 13:52:13 +02004129 *'go-p'*
Bram Moolenaar071d4272004-06-13 20:20:40 +00004130 'p' Use Pointer callbacks for X11 GUI. This is required for some
4131 window managers. If the cursor is not blinking or hollow at
4132 the right moment, try adding this flag. This must be done
Bram Moolenaar910f66f2006-04-05 20:41:53 +00004133 before starting the GUI. Set it in your |gvimrc|. Adding or
Bram Moolenaar071d4272004-06-13 20:20:40 +00004134 removing it after the GUI has started has no effect.
Bram Moolenaar0bc380a2010-07-10 13:52:13 +02004135 *'go-F'*
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00004136 'F' Add a footer. Only for Motif. See |gui-footer|.
Bram Moolenaar8ac44152017-11-09 18:33:29 +01004137 *'go-k'*
4138 'k' Keep the GUI window size when adding/removing a scrollbar, or
4139 toolbar, tabline, etc. Instead, the behavior is similar to
4140 when the window is maximized and will adjust 'lines' and
4141 'columns' to fit to the window. Without the 'k' flag Vim will
Bram Moolenaar51b0f372017-11-18 18:52:04 +01004142 try to keep 'lines' and 'columns' the same when adding and
Bram Moolenaar8ac44152017-11-09 18:33:29 +01004143 removing GUI components.

Bram Moolenaara23ccb82006-02-27 00:08:02 +00004160 The format of this option is like that of 'statusline'.
Bram Moolenaar57657d82006-04-21 22:12:41 +00004161 'guitabtooltip' is used for the tooltip, see below.
Bram Moolenaar51628222016-12-01 23:03:28 +01004162 The expression will be evaluated in the |sandbox| when set from a
4163 modeline, see |sandbox-option|.
Bram Moolenaar110289e2019-05-23 15:38:06 +02004164 This option cannot be set in a modeline when 'modelineexpr' is off.

Bram Moolenaar5c8837f2006-02-25 21:52:33 +00004166 Only used when the GUI tab pages line is displayed. 'e' must be
4167 present in 'guioptions'. For the non-GUI tab pages line 'tabline' is
4168 used.

4176 This option is otherwise just like 'guitablabel' above.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01004177 You can include a line break. Simplest method is to use |:let|: >

Bram Moolenaar071d4272004-06-13 20:20:40 +00004185 Name of the main help file. All distributed help files should be
4186 placed together in one directory. Additionally, all "doc" directories
4187 in 'runtimepath' will be used.
4188 Environment variables are expanded |:set_env|. For example:
4189 "$VIMRUNTIME/doc/help.txt". If $VIMRUNTIME is not set, $VIM is also
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00004190 tried. Also see |$VIMRUNTIME| and |option-backslash| about including
Bram Moolenaar071d4272004-06-13 20:20:40 +00004191 spaces and backslashes.
4192 This option cannot be set from a |modeline| or in the |sandbox|, for
4193 security reasons.

Bram Moolenaar071d4272004-06-13 20:20:40 +00004198 Minimal initial height of the help window when it is opened with the
4199 ":help" command. The initial height of the help window is half of the
4200 current window, or (when the 'ea' option is on) the same as other
4201 windows. When the height is less than 'helpheight', the height is
4202 set to 'helpheight'. Set to zero to disable.

Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01004209 Comma-separated list of languages. Vim will use the first language
Bram Moolenaar071d4272004-06-13 20:20:40 +00004210 for which the desired help can be found. The English help will always
4211 be used as a last resort. You can add "en" to prefer English over
4212 another language, but that will only find tags that exist in that
4213 language and not in the English help.
4214 Example: >
4215 :set helplang=de,it
4216< This will first search German, then Italian and finally English help
4217 files.
4218 When using |CTRL-]| and ":help!" in a non-English help file Vim will
4219 try to find the tag in the current language before using this option.
4220 See |help-translated|.

4227 displayed in another window, it does not become hidden, of course.
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01004228
Bram Moolenaar071d4272004-06-13 20:20:40 +00004229 The commands that move through the buffer list sometimes make a buffer
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01004230 hidden even if the 'hidden' option is off when these three are true:
4231 - the buffer is modified
4232 - 'autowrite' is off or writing is not possible
4233 - the '!' flag was used
4234 Also see |windows.txt|.
4235
Bram Moolenaarcfbc5ee2004-07-02 15:38:35 +00004236 To only make one buffer hidden use the 'bufhidden' option.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004237 This option is set for one command with ":hide {command}" |:hide|.
4238 WARNING: It's easy to forget that you have changes in hidden buffers.

Bram Moolenaar78159bb2014-06-25 11:48:54 +02004350 The maximum value is 10000.

4379 When there is a previous search pattern, highlight all its matches.
4380 The type of highlighting used can be set with the 'l' occasion in the
4381 'highlight' option. This uses the "Search" highlight group by
4382 default. Note that only the matching text is highlighted, any offsets
Bram Moolenaarcfa8f9a2022-06-03 21:59:47 +01004383 are not applied. If the "CurSearch" highlight group is set then the
4384 current match is highlighted with that.
Bram Moolenaar036986f2017-03-16 17:41:02 +01004385 See also: 'incsearch' and |:match|.
4386 When you get bored looking at the highlighted matches, you can turn it
4387 off with |:nohlsearch|. This does not change the option value, as
4388 soon as you use a search command, the highlighting comes back.
4389 'redrawtime' specifies the maximum time spent on finding matches.
4390 When the search pattern can match an end-of-line, Vim will try to
4391 highlight all of the matched text. However, this depends on where the
4392 search starts. This will be the first line in the window or the first
4393 line below a closed fold. A match in a previous line which is not
4394 drawn may not continue in a newly drawn line.
4395 You can specify whether the highlight status is restored on startup
4396 with the 'h' flag in 'viminfo' |viminfo-h|.
4397 NOTE: This option is reset when 'compatible' is set.

4470 You can't use this option to change the activation key, the option
4471 tells Vim what the key is.
4472 Format:
4473 [MODIFIER_FLAG-]KEY_STRING

4484 Combinations are allowed, for example "S-C-space" or "SC-space" are
4485 both shift+ctrl+space.
4486 See <X11/keysymdef.h> and XStringToKeysym for KEY_STRING.
4487
4488 Example: >

Bram Moolenaar5c6dbcb2017-08-30 22:00:20 +02004583 |single-repeat|, etc. Therefore over-the-spot style becomes the

Bram Moolenaarf4b8e572004-06-24 15:53:16 +00004594 Pattern to be used to find an include command. It is a search
Bram Moolenaar071d4272004-06-13 20:20:40 +00004595 pattern, just like for the "/" command (See |pattern|). The default

4598 Normally the 'isfname' option is used to recognize the file name that
Bram Moolenaar482aaeb2005-09-29 18:26:07 +00004599 comes after the matched pattern. But if "\zs" appears in the pattern
4600 then the text matched from "\zs" to the end, or until "\ze" if it
4601 appears, is used as the file name. Use this to include characters
4602 that are not in 'isfname', such as a space. You can then use
4603 'includeexpr' to process the matched text.
Bram Moolenaar1e015462005-09-25 22:16:38 +00004604 See |option-backslash| about including spaces and backslashes.

Bram Moolenaar071d4272004-06-13 20:20:40 +00004706 when the expression is evaluated (but it may be moved around).
Bram Moolenaar6f4754b2022-01-23 12:07:04 +00004707
Yegappan Lakshmanan8bb65f22021-12-26 10:51:39 +00004708 If the expression starts with s: or |<SID>|, then it is replaced with
4709 the script ID (|local-function|). Example: >
4710 set indentexpr=s:MyIndentExpr()
4711 set indentexpr=<SID>SomeIndentExpr()
Bram Moolenaar6f4754b2022-01-23 12:07:04 +00004712< Otherwise, the expression is evaluated in the context of the script
4713 where the option was set, thus script-local items are available.
4714
Bram Moolenaara4e0b972022-10-01 19:43:52 +01004715 The advantage of using a function call without arguments is that it is
4716 faster, see |expr-option-function|.
4717
Bram Moolenaar071d4272004-06-13 20:20:40 +00004718 The expression must return the number of spaces worth of indent. It
4719 can return "-1" to keep the current indent (this means 'autoindent' is
4720 used for the indent).
4721 Functions useful for computing the indent are |indent()|, |cindent()|
4722 and |lispindent()|.
4723 The evaluation of the expression must not have side effects! It must
4724 not change the text, jump to another window, etc. Afterwards the
4725 cursor position is always restored, thus the cursor may be moved.
4726 Normally this option would be set to call a function: >
4727 :set indentexpr=GetMyIndent()
4728< Error messages will be suppressed, unless the 'debug' option contains
4729 "msg".

Bram Moolenaar110289e2019-05-23 15:38:06 +02004735 This option cannot be set in a modeline when 'modelineexpr' is off.

Bram Moolenaar071d4272004-06-13 20:20:40 +00004743 A list of keys that, when typed in Insert mode, cause reindenting of
4744 the current line. Only happens if 'indentexpr' isn't empty.

Bram Moolenaar071d4272004-06-13 20:20:40 +00004751 When doing keyword completion in insert mode |ins-completion|, and
Bram Moolenaar446cb832008-06-24 21:56:24 +00004752 'ignorecase' is also on, the case of the match is adjusted depending
4753 on the typed text. If the typed text contains a lowercase letter
4754 where the match has an upper case letter, the completed part is made
4755 lowercase. If the typed text has no lowercase letters and the match
4756 has a lowercase letter where the typed text has an uppercase letter,
4757 and there is a letter before it, the completed part is made uppercase.
4758 With 'noinfercase' the match is used as-is.

4760 *'insertmode'* *'im'* *'noinsertmode'* *'noim'*
4761'insertmode' 'im' boolean (default off)
4762 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00004763 Makes Vim work in a way that Insert mode is the default mode. Useful
4764 if you want to use Vim as a modeless editor. Used for |evim|.
4765 These Insert mode commands will be useful:
4766 - Use the cursor keys to move around.
Bram Moolenaardc1f1642016-08-16 18:33:43 +02004767 - Use CTRL-O to execute one Normal mode command |i_CTRL-O|. When
Bram Moolenaar071d4272004-06-13 20:20:40 +00004768 this is a mapping, it is executed as if 'insertmode' was off.
4769 Normal mode remains active until the mapping is finished.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004770 - Use CTRL-L to execute a number of Normal mode commands, then use
Bram Moolenaar488c6512005-08-11 20:09:58 +00004771 <Esc> to get back to Insert mode. Note that CTRL-L moves the cursor
4772 left, like <Esc> does when 'insertmode' isn't set. |i_CTRL-L|
Bram Moolenaar071d4272004-06-13 20:20:40 +00004773
4774 These items change when 'insertmode' is set:
4775 - when starting to edit of a file, Vim goes to Insert mode.
4776 - <Esc> in Insert mode is a no-op and beeps.
4777 - <Esc> in Normal mode makes Vim go to Insert mode.
4778 - CTRL-L in Insert mode is a command, it is not inserted.
4779 - CTRL-Z in Insert mode suspends Vim, see |CTRL-Z|. *i_CTRL-Z*
4780 However, when <Esc> is used inside a mapping, it behaves like
4781 'insertmode' was not set. This was done to be able to use the same
4782 mappings with 'insertmode' set or not set.
4783 When executing commands with |:normal| 'insertmode' is not used.
4784
4785 NOTE: This option is reset when 'compatible' is set.
4786
4787 *'isfname'* *'isf'*
Bram Moolenaar6f345a12019-12-17 21:27:18 +01004788'isfname' 'isf' string (default for Win32:

Bram Moolenaar071d4272004-06-13 20:20:40 +00004795 The characters specified by this option are included in file names and
4796 path names. Filenames are used for commands like "gf", "[i" and in
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00004797 the tags file. It is also used for "\f" in a |pattern|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004798 Multi-byte characters 256 and above are always included, only the
4799 characters up to 255 are specified with this option.
4800 For UTF-8 the characters 0xa0 to 0xff are included as well.
Bram Moolenaar446cb832008-06-24 21:56:24 +00004801 Think twice before adding white space to this option. Although a
4802 space may appear inside a file name, the effect will be that Vim
4803 doesn't know where a file name starts or ends when doing completion.
4804 It most likely works better without a space in 'isfname'.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004805
4806 Note that on systems using a backslash as path separator, Vim tries to
4807 do its best to make it work as you would expect. That is a bit
4808 tricky, since Vi originally used the backslash to escape special
4809 characters. Vim will not remove a backslash in front of a normal file
4810 name character on these systems, but it will on Unix and alikes. The
4811 '&' and '^' are not included by default, because these are special for
4812 cmd.exe.
4813
4814 The format of this option is a list of parts, separated with commas.
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00004815 Each part can be a single character number or a range. A range is two
4816 character numbers with '-' in between. A character number can be a
Bram Moolenaar071d4272004-06-13 20:20:40 +00004817 decimal number between 0 and 255 or the ASCII character itself (does
4818 not work for digits). Example:
4819 "_,-,128-140,#-43" (include '_' and '-' and the range
4820 128 to 140 and '#' to 43)
4821 If a part starts with '^', the following character number or range
4822 will be excluded from the option. The option is interpreted from left
4823 to right. Put the excluded character after the range where it is
4824 included. To include '^' itself use it as the last character of the
4825 option or the end of a range. Example:
4826 "^a-z,#,^" (exclude 'a' to 'z', include '#' and '^')
4827 If the character is '@', all characters where isalpha() returns TRUE
4828 are included. Normally these are the characters a to z and A to Z,
4829 plus accented characters. To include '@' itself use "@-@". Examples:
4830 "@,^a-z" All alphabetic characters, excluding lower
Bram Moolenaar446cb832008-06-24 21:56:24 +00004831 case ASCII letters.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004832 "a-z,A-Z,@-@" All letters plus the '@' character.
4833 A comma can be included by using it where a character number is
4834 expected. Example:
4835 "48-57,,,_" Digits, comma and underscore.
4836 A comma can be excluded by prepending a '^'. Example:
4837 " -~,^,,9" All characters from space to '~', excluding
4838 comma, plus <Tab>.
4839 See |option-backslash| about including spaces and backslashes.

4848 match of the 'define' option. It is also used for "\i" in a
Bram Moolenaar582fd852005-03-28 20:58:01 +00004849 |pattern|. See 'isfname' for a description of the format of this
Bram Moolenaar95bafa22018-10-02 13:26:25 +02004850 option. For '@' only characters up to 255 are used.
Bram Moolenaar071d4272004-06-13 20:20:40 +00004851 Careful: If you change this option, it might break expanding
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00004852 environment variables. E.g., when '/' is included and Vim tries to
Bram Moolenaar071d4272004-06-13 20:20:40 +00004853 expand "$HOME/.viminfo". Maybe you should change 'iskeyword' instead.

4865 that is not white space or punctuation).
Bram Moolenaar95bafa22018-10-02 13:26:25 +02004866 For C programs you could use "a-z,A-Z,48-57,_,.,-,>".

4934 :set key=
4935< It is not possible to get the value of this option with ":set key" or
4936 "echo &key". This is to avoid showing it to someone who shouldn't

4960 startsel Using a shifted special key starts selection (either
4961 Select mode or Visual mode, depending on "key" being
4962 present in 'selectmode').
4963 stopsel Using a not-shifted special key stops selection.
4964 Special keys in this context are the cursor keys, <End>, <Home>,
4965 <PageUp> and <PageDown>.

4974 mok2 modifyOtherKeys level 2, as supported by xterm
4975 kitty Kitty keyboard protocol, as supported by Kitty
4976
Bram Moolenaara87749e2022-11-30 10:23:17 +00004977 The option value is a list of comma separated items. Each item has
Bram Moolenaar63a2e362022-11-23 20:20:18 +00004978 a pattern that is matched against the 'term' option, a colon and the
4979 protocol name to be used. To illustrate this, the default value would
4980 be set with: >
4981 set keyprotocol=kitty:kitty,foot:kitty,wezterm:kitty,xterm:mok2
4982
4983< This means that when 'term' contains "kitty, "foot" or "wezterm"

Bram Moolenaar938ae282023-02-20 20:44:55 +00004985 "xterm" somewhere, then the "mok2" protocol is used.
Bram Moolenaar63a2e362022-11-23 20:20:18 +00004986
4987 The first match is used, thus if you want to have "kitty" use the
4988 kitty protocol, but "badkitty" not, then you should match "badkitty"
4989 first and use the "none" value: >

5020'keywordprg' 'kp' string (default "man" or "man -s", DOS: ":help",
Bram Moolenaar2ff8b642016-05-24 10:46:45 +02005021 VMS: "help")

Bram Moolenaar071d4272004-06-13 20:20:40 +00005023 Program to use for the |K| command. Environment variables are
5024 expanded |:set_env|. ":help" may be used to access the Vim internal
5025 help. (Note that previously setting the global option to the empty
5026 value did this, which is now deprecated.)
Bram Moolenaar2ff8b642016-05-24 10:46:45 +02005027 When the first character is ":", the command is invoked as a Vim
Bram Moolenaarb529cfb2022-07-25 15:42:07 +01005028 Ex command with [count] added as an argument if it is not zero.
Bram Moolenaar2ff8b642016-05-24 10:46:45 +02005029 When "man", "man -s" or an Ex command is used, Vim will automatically
5030 translate a count for the "K" command and pass it as the first
5031 argument. For "man -s" the "-s" is removed when there is no count.
Bram Moolenaar071d4272004-06-13 20:20:40 +00005032 See |option-backslash| about including spaces and backslashes.

Bram Moolenaar071d4272004-06-13 20:20:40 +00005041 {only available when compiled with the |+langmap|
5042 feature}
5043 This option allows switching your keyboard into a special language
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00005044 mode. When you are typing text in Insert mode the characters are
Bram Moolenaarfa735342016-01-03 22:14:44 +01005045 inserted directly. When in Normal mode the 'langmap' option takes
Bram Moolenaar071d4272004-06-13 20:20:40 +00005046 care of translating these special characters to the original meaning
5047 of the key. This means you don't have to change the keyboard mode to
5048 be able to execute Normal mode commands.
5049 This is the opposite of the 'keymap' option, where characters are
5050 mapped in Insert mode.
Bram Moolenaarb17893a2020-03-14 08:19:51 +01005051 Also consider setting 'langremap' to off, to prevent 'langmap' from
5052 applying to characters resulting from a mapping.
Bram Moolenaare968e362014-05-13 20:23:24 +02005053 This option cannot be set from a |modeline| or in the |sandbox|, for
5054 security reasons.

5059 :set langmap=zy,yz,ZY,YZ
5060<
5061 The 'langmap' option is a list of parts, separated with commas. Each
5062 part can be in one of two forms:
5063 1. A list of pairs. Each pair is a "from" character immediately
5064 followed by the "to" character. Examples: "aA", "aAbBcC".
5065 2. A list of "from" characters, a semi-colon and a list of "to"
5066 characters. Example: "abc;ABC"
5067 Example: "aA,fgh;FGH,cCdDeE"
5068 Special characters need to be preceded with a backslash. These are
Bram Moolenaar4f4d51a2020-10-11 13:57:40 +02005069 ";", ',', '"', '|' and backslash itself.
Bram Moolenaar071d4272004-06-13 20:20:40 +00005070
5071 This will allow you to activate vim actions without having to switch
5072 back and forth between the languages. Your language characters will
5073 be understood as normal vim English characters (according to the
5074 langmap mappings) in the following cases:
5075 o Normal/Visual mode (commands, buffer/register names, user mappings)
5076 o Insert/Replace Mode: Register names after CTRL-R
5077 o Insert/Replace Mode: Mappings
5078 Characters entered in Command-line mode will NOT be affected by
5079 this option. Note that this option can be changed at any time
5080 allowing to switch between mappings for different languages/encodings.
5081 Use a mapping to avoid having to type it each time!

Bram Moolenaar4391cf92014-11-05 17:44:52 +01005122 a mapping. This basically means, if you noticed that setting
Bram Moolenaare4a3bcf2016-08-26 19:52:37 +02005123 'langmap' disables some of your mappings, try resetting this option.
5124 This option defaults to on for backwards compatibility. Set it off if

Bram Moolenaara57b5532022-06-24 11:48:03 +01005145 This may occasionally cause display errors. It is only meant to be set

Bram Moolenaar946e27a2014-06-25 18:50:27 +02005154 If on, Vim will wrap long lines at a character in 'breakat' rather
Bram Moolenaar071d4272004-06-13 20:20:40 +00005155 than at the last character that fits on the screen. Unlike
5156 'wrapmargin' and 'textwidth', this does not insert <EOL>s in the file,
Bram Moolenaar946e27a2014-06-25 18:50:27 +02005157 it only affects the way the file is displayed, not its contents.
5158 If 'breakindent' is set, line is visually indented. Then, the value
5159 of 'showbreak' is used to put in front of wrapped lines. This option
Bram Moolenaar86b17e92014-07-02 20:00:47 +02005160 is not used when the 'wrap' option is off.
Bram Moolenaar071d4272004-06-13 20:20:40 +00005161 Note that <Tab> characters after an <EOL> are mostly not displayed

5165'lines' number (default 24 or terminal height)
5166 global
5167 Number of lines of the Vim window.
5168 Normally you don't need to set this. It is done automatically by the
Bram Moolenaar7c626922005-02-07 22:01:03 +00005169 terminal initialization code. Also see |posix-screen-size|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00005170 When Vim is running in the GUI or in a resizable window, setting this
5171 option will cause the window size to be changed. When you only want
5172 to use the size for the GUI, put the command in your |gvimrc| file.
5173 Vim limits the number of lines to what fits on the screen. You can
5174 use this command to get the tallest window possible: >
5175 :set lines=999
Bram Moolenaarf4d11452005-12-02 00:46:37 +00005176< Minimum value is 2, maximum value is 1000.
Bram Moolenaardc1f1642016-08-16 18:33:43 +02005177 If you get fewer lines than expected, check the 'guiheadroom' option.
Bram Moolenaar071d4272004-06-13 20:20:40 +00005178 When you set this option and Vim is unable to change the physical
5179 number of lines of the display, the display may be messed up.

5185 Number of pixel lines inserted between characters. Useful if the font
5186 uses the full character cell height, making lines touch each other.
5187 When non-zero there is room for underlining.
Bram Moolenaarbc7aa852005-03-06 23:38:09 +00005188 With some fonts there can be too much room between lines (to have
5189 space for ascents and descents). Then it makes sense to set
5190 'linespace' to a negative value. This may cause display problems

5197 the next line to Lisp standards (well, sort of). Also happens with
5198 "cc" or "S". 'autoindent' must also be on for this to work. The 'p'
5199 flag in 'cpoptions' changes the method of indenting: Vi compatible or
5200 better. Also see 'lispwords'.
5201 The '-' character is included in keyword characters. Redefines the

Bram Moolenaare4efc3b2005-03-07 23:16:51 +00005510 Running into the limit often means that the pattern is very

5548 Parameters for |:mkspell|. This tunes when to start compressing the
5549 word tree. Compression can be slow when there are many words, but
5550 it's needed to avoid running out of memory. The amount of memory used
5551 per word depends very much on how similar the words are, that's why
5552 this tuning is complicated.
5553
5554 There are three numbers, separated by commas:
5555 {start},{inc},{added}
5556
5557 For most languages the uncompressed word tree fits in memory. {start}
5558 gives the amount of memory in Kbyte that can be used before any
5559 compression is done. It should be a bit smaller than the amount of
5560 memory that is available to Vim.
5561
5562 When going over the {start} limit the {inc} number specifies the
5563 amount of memory in Kbyte that can be allocated before another
5564 compression is done. A low number means compression is done after
5565 less words are added, which is slow. A high number means more memory
5566 will be allocated.
5567
5568 After doing compression, {added} times 1024 words can be added before
5569 the {inc} limit is ignored and compression is done when any extra
5570 amount of memory is needed. A low number means there is a smaller
5571 chance of hitting the {inc} limit, less memory is used but it's
5572 slower.
5573
5574 The languages for which these numbers are important are Italian and
5575 Hungarian. The default works for when you have about 512 Mbyte. If
5576 you have 1 Gbyte you could use: >
5577 :set mkspellmem=900000,3000,800
5578< If you have less than 512 Mbyte |:mkspell| may fail for some
5579 languages, no matter what you set 'mkspellmem' to.

Bram Moolenaar5666fcd2019-12-26 14:35:26 +01005656 Enable the use of the mouse. Works for most terminals (xterm, Win32
5657 |win32-mouse|, QNX pterm, *BSD console with sysmouse and Linux console
5658 with gpm). For using the mouse in the GUI, see |gui-mouse|. The
5659 mouse can be enabled for different modes:
Bram Moolenaar7f2e9d72017-11-11 20:58:53 +01005660 n Normal mode and Terminal modes
Bram Moolenaar071d4272004-06-13 20:20:40 +00005661 v Visual mode
5662 i Insert mode
5663 c Command-line mode
5664 h all previous modes when editing a help file
5665 a all previous modes
5666 r for |hit-enter| and |more-prompt| prompt
Bram Moolenaar95bafa22018-10-02 13:26:25 +02005667 Normally you would enable the mouse in all five modes with: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00005668 :set mouse=a
Bram Moolenaar5b418992019-10-27 18:50:25 +01005669< If your terminal can't overrule the mouse events going to the
5670 application, use: >
5671 :set mouse=nvi
Bram Moolenaar65e0d772020-06-14 17:29:55 +02005672< Then you can press ":", select text for the system, and press Esc to go
Bram Moolenaar5b418992019-10-27 18:50:25 +01005673 back to Vim using the mouse events.
5674 In |defaults.vim| "nvi" is used if the 'term' option is not matching
5675 "xterm".
5676
5677 When the mouse is not enabled, the GUI will still use the mouse for
Bram Moolenaar071d4272004-06-13 20:20:40 +00005678 modeless selection. This doesn't move the text cursor.
5679
5680 See |mouse-using|. Also see |'clipboard'|.
5681
5682 Note: When enabling the mouse in a terminal, copy/paste will use the
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00005683 "* register if there is access to an X-server. The xterm handling of
Bram Moolenaar071d4272004-06-13 20:20:40 +00005684 the mouse buttons can still be used by keeping the shift key pressed.

5691 The window that the mouse pointer is on is automatically activated.
5692 When changing the window layout or window focus in another way, the
5693 mouse pointer is moved to the window with keyboard focus. Off is the
5694 default because it makes using the pull down menus a little goofy, as
5695 a pointer transit may activate a window unintentionally.

Bram Moolenaar071d4272004-06-13 20:20:40 +00005709 Sets the model to use for the mouse. The name mostly specifies what
5710 the right mouse button is used for:
5711 extend Right mouse button extends a selection. This works
5712 like in an xterm.
5713 popup Right mouse button pops up a menu. The shifted left
5714 mouse button extends a selection. This works like
Bram Moolenaar582fd852005-03-28 20:58:01 +00005715 with Microsoft Windows.
Bram Moolenaar071d4272004-06-13 20:20:40 +00005716 popup_setpos Like "popup", but the cursor will be moved to the
5717 position where the mouse was clicked, and thus the
5718 selected operation will act upon the clicked object.
5719 If clicking inside a selection, that selection will
Bram Moolenaar582fd852005-03-28 20:58:01 +00005720 be acted upon, i.e. no cursor move. This implies of
Bram Moolenaar071d4272004-06-13 20:20:40 +00005721 course, that right clicking outside a selection will
5722 end Visual mode.
5723 Overview of what button does what for each model:
5724 mouse extend popup(_setpos) ~
5725 left click place cursor place cursor
5726 left drag start selection start selection
5727 shift-left search word extend selection
5728 right click extend selection popup menu (place cursor)
5729 right drag extend selection -
5730 middle click paste paste
5731
5732 In the "popup" model the right mouse button produces a pop-up menu.
5733 You need to define this first, see |popup-menu|.
5734
5735 Note that you can further refine the meaning of buttons with mappings.
5736 See |gui-mouse-mapping|. But mappings are NOT used for modeless
5737 selection (because that's handled in the GUI code directly).
5738
5739 The 'mousemodel' option is set by the |:behave| command.

5744 {only works in the GUI}
5745 When on, mouse move events are delivered to the input queue and are
5746 available for mapping. The default, off, avoids the mouse movement
5747 overhead except when needed. See |gui-mouse-mapping|.
5748 Warning: Setting this option can make pending mappings to be aborted
5749 when the mouse is moved.
5750 Currently only works in the GUI, may be made to work in a terminal

5760 This option tells Vim what the mouse pointer should look like in
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01005761 different modes. The option is a comma-separated list of parts, much
Bram Moolenaar071d4272004-06-13 20:20:40 +00005762 like used for 'guicursor'. Each part consist of a mode/location-list
5763 and an argument-list:
5764 mode-list:shape,mode-list:shape,..
5765 The mode-list is a dash separated list of these modes/locations:
5766 In a normal window: ~
5767 n Normal mode
5768 v Visual mode
5769 ve Visual mode with 'selection' "exclusive" (same as 'v',
5770 if not specified)
5771 o Operator-pending mode
5772 i Insert mode
5773 r Replace mode
5774
5775 Others: ~
5776 c appending to the command-line
5777 ci inserting in the command-line
5778 cr replacing in the command-line
5779 m at the 'Hit ENTER' or 'More' prompts
5780 ml idem, but cursor in the last line
5781 e any mode, pointer below last window
5782 s any mode, pointer on a status line
5783 sd any mode, while dragging a status line
5784 vs any mode, pointer on a vertical separator line
5785 vd any mode, while dragging a vertical separator line
5786 a everywhere
5787
5788 The shape is one of the following:
5789 avail name looks like ~
5790 w x arrow Normal mouse pointer
5791 w x blank no pointer at all (use with care!)
5792 w x beam I-beam
5793 w x updown up-down sizing arrows
5794 w x leftright left-right sizing arrows
5795 w x busy The system's usual busy pointer
5796 w x no The system's usual 'no input' pointer
5797 x udsizing indicates up-down resizing
5798 x lrsizing indicates left-right resizing
5799 x crosshair like a big thin +
5800 x hand1 black hand
5801 x hand2 white hand
5802 x pencil what you write with
5803 x question big ?
5804 x rightup-arrow arrow pointing right-up
5805 w x up-arrow arrow pointing up
5806 x <number> any X11 pointer number (see X11/cursorfont.h)
5807
5808 The "avail" column contains a 'w' if the shape is available for Win32,
5809 x for X11.
5810 Any modes not specified or shapes not available use the normal mouse
5811 pointer.
5812
5813 Example: >
5814 :set mouseshape=s:udsizing,m:no
5815< will make the mouse turn to a sizing arrow over the status lines and

5882 Using CTRL-X on "2020" in "9-2020" results in "9-2019"
5883 (without "unsigned" it would become "9-2021").
5884 Using CTRL-A on "2020" in "9-2020" results in "9-2021"
5885 (without "unsigned" it would become "9-2019").

Bram Moolenaar071d4272004-06-13 20:20:40 +00005888 Numbers which simply begin with a digit in the range 1-9 are always

Bram Moolenaar071d4272004-06-13 20:20:40 +00005900 When a long, wrapped line doesn't start with the first character, '-'
5901 characters are put before the number.

5924 with a line number. Since one space is always between the number and
5925 the text, there is one less character for the number itself.

5928 rows in the window, depending on whether 'number' or 'relativenumber'
5929 is set. Thus with the Vim default of 4 there is room for a line number
5930 up to 999. When the buffer has 1000 lines five columns will be used.
Bram Moolenaarf8a07122019-07-01 22:06:07 +02005931 The minimum value is 1, the maximum value is 20.

Bram Moolenaarf4b8e572004-06-24 15:53:16 +00005992 Put Vim in Paste mode. This is useful if you want to cut or copy
5993 some text from one window and paste it in Vim. This will avoid
Bram Moolenaar071d4272004-06-13 20:20:40 +00005994 unexpected effects.
5995 Setting this option is useful when using Vim in a terminal, where Vim
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00005996 cannot distinguish between typed text and pasted text. In the GUI, Vim
Bram Moolenaar071d4272004-06-13 20:20:40 +00005997 knows about pasting and will mostly do the right thing without 'paste'
5998 being set. The same is true for a terminal where Vim handles the
5999 mouse clicks itself.
Bram Moolenaar2ce06f62005-01-31 19:19:04 +00006000 This option is reset when starting the GUI. Thus if you set it in
6001 your .vimrc it will work in a terminal, but not in the GUI. Setting
6002 'paste' in the GUI has side effects: e.g., the Paste toolbar button
6003 will no longer work in Insert mode, because it uses a mapping.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006004 When the 'paste' option is switched on (also when it was already on):
6005 - mapping in Insert mode and Command-line mode is disabled
6006 - abbreviations are disabled
Bram Moolenaar071d4272004-06-13 20:20:40 +00006007 - 'autoindent' is reset

Bram Moolenaar071d4272004-06-13 20:20:40 +00006018 These options keep their value, but their effect is disabled:
Bram Moolenaar071d4272004-06-13 20:20:40 +00006019 - 'cindent'
Bram Moolenaar4d8f4762021-06-27 15:18:56 +02006020 - 'formatoptions' is used like it is empty
Bram Moolenaarca635012015-09-25 20:34:21 +02006021 - 'indentexpr'
6022 - 'lisp'
Bram Moolenaar4d8f4762021-06-27 15:18:56 +02006023 - 'smartindent'
Bram Moolenaar071d4272004-06-13 20:20:40 +00006024 NOTE: When you start editing another file while the 'paste' option is
6025 on, settings from the modelines or autocommands may change the
6026 settings again, causing trouble when pasting text. You might want to
6027 set the 'paste' option again.
6028 When the 'paste' option is reset the mentioned options are restored to
6029 the value before the moment 'paste' was switched from off to on.
6030 Resetting 'paste' before ever setting it does not have any effect.
6031 Since mapping doesn't work while 'paste' is active, you need to use
6032 the 'pastetoggle' option to toggle the 'paste' option with some key.

Bram Moolenaar071d4272004-06-13 20:20:40 +00006037 When non-empty, specifies the key sequence that toggles the 'paste'
6038 option. This is like specifying a mapping: >
6039 :map {keys} :set invpaste<CR>
6040< Where {keys} is the value of 'pastetoggle'.
6041 The difference is that it will work even when 'paste' is set.
6042 'pastetoggle' works in Insert mode and Normal mode, but not in
6043 Command-line mode.
6044 Mappings are checked first, thus overrule 'pastetoggle'. However,
6045 when 'paste' is on mappings are ignored in Insert mode, thus you can do
6046 this: >
6047 :map <F10> :set paste<CR>
6048 :map <F11> :set nopaste<CR>
6049 :imap <F10> <C-O>:set paste<CR>
6050 :imap <F11> <nop>
6051 :set pastetoggle=<F11>
6052< This will make <F10> start paste mode and <F11> stop paste mode.
6053 Note that typing <F10> in paste mode inserts "<F10>", since in paste
6054 mode everything is inserted literally, except the 'pastetoggle' key
6055 sequence.
Bram Moolenaar446cb832008-06-24 21:56:24 +00006056 When the value has several bytes 'ttimeoutlen' applies.

Bram Moolenaar071d4272004-06-13 20:20:40 +00006071 When non-empty the oldest version of a file is kept. This can be used
6072 to keep the original version of a file if you are changing files in a
6073 source distribution. Only the first time that a file is written a
6074 copy of the original file will be kept. The name of the copy is the
6075 name of the original file with the string in the 'patchmode' option
6076 appended. This option should start with a dot. Use a string like
Bram Moolenaardf980db2017-12-24 13:22:00 +01006077 ".orig" or ".org". 'backupdir' must not be empty for this to work
6078 (Detail: The backup file is renamed to the patchmode file after the
6079 new file has been successfully written, that's why it must be possible
6080 to write a backup file). If there was no file to be backed up, an
6081 empty file is created.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006082 When the 'backupskip' pattern matches, a patchmode file is not made.
6083 Using 'patchmode' for compressed files appends the extension at the
6084 end (e.g., "file.gz.orig"), thus the resulting name isn't always
6085 recognized as a compressed file.

6096 option may be relative or absolute.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006097 - Use commas to separate directory names: >
6098 :set path=.,/usr/local/include,/usr/include
6099< - Spaces can also be used to separate directory names (for backwards
6100 compatibility with version 3.0). To have a space in a directory
6101 name, precede it with an extra backslash, and escape the space: >
6102 :set path=.,/dir/with\\\ space
6103< - To include a comma in a directory name precede it with an extra
6104 backslash: >

6112 - Environment variables are expanded |:set_env|.
6113 - When using |netrw.vim| URLs can be used. For example, adding

Bram Moolenaarf4b8e572004-06-24 15:53:16 +00006123 The maximum length is limited. How much depends on the system, mostly
Bram Moolenaar071d4272004-06-13 20:20:40 +00006124 it is something like 256 or 1024 characters.
6125 You can check if all the include files are found, using the value of
6126 'path', see |:checkpath|.
6127 The use of |:set+=| and |:set-=| is preferred when adding or removing
6128 directories from the list. This avoids problems when a future version

6132 :set path+=
6133< To use an environment variable, you probably need to replace the

Bram Moolenaar071d4272004-06-13 20:20:40 +00006154 When changing the indent of the current line, preserve as much of the
6155 indent structure as possible. Normally the indent is replaced by a
6156 series of tabs followed by spaces as required (unless |'expandtab'| is
6157 enabled, in which case only spaces are used). Enabling this option
6158 means the indent will preserve as many existing characters as possible
6159 for indenting, and only add additional tabs or spaces as required.
Bram Moolenaar446cb832008-06-24 21:56:24 +00006160 'expandtab' does not apply to the preserved white space, a Tab remains
6161 a Tab.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006162 NOTE: When using ">>" multiple times the resulting indent is a mix of

Bram Moolenaarfda37292014-11-05 14:27:36 +01006421 Using automatic selection enables Vim to switch the engine, if the

6432 having to calculate it yourself. Especially useful in combination with
6433 other commands (e.g. y d c < > gq gw =).
6434 When the 'n' option is excluded from 'cpoptions' a wrapped
6435 line will not use the column of line numbers (this is the default when
6436 'compatible' isn't set).
6437 The 'numberwidth' option can be used to set the room used for the line
6438 number.
6439 When a long, wrapped line doesn't start with the first character, '-'
6440 characters are put before the number.

Bram Moolenaara3227e22006-03-08 21:32:40 +00006453 NOTE: To avoid portability problems with Vim scripts, always keep
6454 this option at the default "on". Only switch it off when working with

6596 Using this option, it is possible to edit files for languages that
6597 are written from the right to the left such as Hebrew and Arabic.
6598 This option is per window, so it is possible to edit mixed files
6599 simultaneously, or to view the same file in both ways (this is
6600 useful whenever you have a mixed text file with both right-to-left
6601 and left-to-right strings so that both sets are displayed properly
6602 in different windows). Also see |rileft.txt|.

Bram Moolenaarf4b8e572004-06-24 15:53:16 +00006743 runtime files. For speed, use as few items as possible and avoid
Bram Moolenaar071d4272004-06-13 20:20:40 +00006744 wildcards.
6745 See |:runtime|.
6746 Example: >
6747 :set runtimepath=~/vimruntime,/mygroup/vim,$VIMRUNTIME
6748< This will use the directory "~/vimruntime" first (containing your
6749 personal Vim runtime files), then "/mygroup/vim" (shared between a
6750 group of people) and finally "$VIMRUNTIME" (the distributed runtime
6751 files).
6752 You probably should always include $VIMRUNTIME somewhere, to use the
6753 distributed runtime files. You can put a directory before $VIMRUNTIME
6754 to find files which replace a distributed runtime files. You can put
6755 a directory after $VIMRUNTIME to find files which add to distributed
6756 runtime files.
Bram Moolenaarb5b75622018-03-09 22:22:21 +01006757 When Vim is started with |--clean| the home directory entries are not
6758 included.

6766 set to half the number of lines in the window when the window size
Bram Moolenaar74667062020-12-28 15:41:41 +01006767 changes. This may happen when enabling the |status-line| or
6768 'tabline' option after setting the 'scroll' option.
6769 If you give a count to the CTRL-U or CTRL-D command it will
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00006770 be used as the new value for 'scroll'. Reset to half the window
Bram Moolenaar25c9c682019-05-05 18:13:34 +02006771 height with ":set scroll=0".

zeertzjq5277cfa2023-09-28 01:00:12 +08006776 See also |scroll-binding|. When this option is set, scrolling the
6777 current window also scrolls other scrollbind windows (windows that
6778 also have this option set). This option is useful for viewing the
Bram Moolenaar071d4272004-06-13 20:20:40 +00006779 differences between two versions of a file, see 'diff'.
6780 See |'scrollopt'| for options that determine how this option should be
6781 interpreted.
6782 This option is mostly reset when splitting a window to edit another
6783 file. This means that ":split | edit file" results in two windows
6784 with scroll-binding, but ":split file" does not.

6789 {only for MS-Windows GUI}
6790 When using the scroll wheel and this option is set, the window under
6791 the mouse pointer is scrolled. With this option off the current
6792 window is scrolled.
Bram Moolenaar5ef1c6a2019-11-10 22:09:11 +01006793 Systems other than MS-Windows always behave like this option is on.

6797 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00006798 Minimal number of lines to scroll when the cursor gets off the
6799 screen (e.g., with "j"). Not used for scroll commands (e.g., CTRL-E,
6800 CTRL-D). Useful if your terminal scrolls very slowly.
Bram Moolenaar1e015462005-09-25 22:16:38 +00006801 When set to a negative number from -1 to -100 this is used as the
6802 percentage of the window height. Thus -50 scrolls half the window
6803 height.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006804 NOTE: This option is set to 1 when 'compatible' is set.

Bram Moolenaar071d4272004-06-13 20:20:40 +00006809 Minimal number of screen lines to keep above and below the cursor.
6810 This will make some context visible around where you are working. If
6811 you set it to a very large value (999) the cursor line will always be
6812 in the middle of the window (except at the start or end of the file or
6813 when long lines wrap).

6821 *'scrollopt'* *'sbo'*
6822'scrollopt' 'sbo' string (default "ver,jump")
6823 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00006824 This is a comma-separated list of words that specifies how
Bram Moolenaar402d2fe2005-04-15 21:00:38 +00006825 'scrollbind' windows should behave. 'sbo' stands for ScrollBind
6826 Options.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006827 The following words are available:
6828 ver Bind vertical scrolling for 'scrollbind' windows
6829 hor Bind horizontal scrolling for 'scrollbind' windows
6830 jump Applies to the offset between two windows for vertical
6831 scrolling. This offset is the difference in the first
6832 displayed line of the bound windows. When moving
6833 around in a window, another 'scrollbind' window may
6834 reach a position before the start or after the end of
6835 the buffer. The offset is not changed though, when
6836 moving back the 'scrollbind' window will try to scroll
6837 to the desired position when possible.
6838 When now making that window the current one, two
6839 things can be done with the relative offset:
6840 1. When "jump" is not included, the relative offset is
6841 adjusted for the scroll position in the new current
6842 window. When going back to the other window, the
Bram Moolenaar02467872007-05-06 13:22:01 +00006843 new relative offset will be used.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006844 2. When "jump" is included, the other windows are
6845 scrolled to keep the same relative offset. When
6846 going back to the other window, it still uses the
6847 same relative offset.
6848 Also see |scroll-binding|.
Bram Moolenaar910f66f2006-04-05 20:41:53 +00006849 When 'diff' mode is active there always is vertical scroll binding,
6850 even when "ver" isn't there.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006851
6852 *'sections'* *'sect'*
6853'sections' 'sect' string (default "SHNHH HUnhsh")
6854 global
6855 Specifies the nroff macros that separate sections. These are pairs of
6856 two letters (See |object-motions|). The default makes a section start
6857 at the nroff macros ".SH", ".NH", ".H", ".HU", ".nh" and ".sh".
6858
6859 *'secure'* *'nosecure'* *E523*
6860'secure' boolean (default off)
6861 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00006862 When on, ":autocmd", shell and write commands are not allowed in
6863 ".vimrc" and ".exrc" in the current directory and map commands are
6864 displayed. Switch it off only if you know that you will not run into
6865 problems, or when the 'exrc' option is off. On Unix this option is
6866 only used if the ".vimrc" or ".exrc" is not owned by you. This can be
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00006867 dangerous if the systems allows users to do a "chown". You better set
Bram Moolenaar071d4272004-06-13 20:20:40 +00006868 'secure' at the end of your ~/.vimrc then.
6869 This option cannot be set from a |modeline| or in the |sandbox|, for
6870 security reasons.
6871
6872 *'selection'* *'sel'*
6873'selection' 'sel' string (default "inclusive")
6874 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00006875 This option defines the behavior of the selection. It is only used
6876 in Visual and Select mode.
6877 Possible values:
6878 value past line inclusive ~
6879 old no yes
6880 inclusive yes yes
6881 exclusive yes no
6882 "past line" means that the cursor is allowed to be positioned one
6883 character past the line.
6884 "inclusive" means that the last character of the selection is included
6885 in an operation. For example, when "x" is used to delete the
6886 selection.
Bram Moolenaare4a3bcf2016-08-26 19:52:37 +02006887 When "old" is used and 'virtualedit' allows the cursor to move past
6888 the end of line the line break still isn't included.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006889 Note that when "exclusive" is used and selecting from the end
6890 backwards, you cannot include the last character of a line, when
6891 starting in Normal mode and 'virtualedit' empty.
6892
6893 The 'selection' option is set by the |:behave| command.
6894
6895 *'selectmode'* *'slm'*
6896'selectmode' 'slm' string (default "")
6897 global
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01006898 This is a comma-separated list of words, which specifies when to start
Bram Moolenaar071d4272004-06-13 20:20:40 +00006899 Select mode instead of Visual mode, when a selection is started.
6900 Possible values:
6901 mouse when using the mouse
6902 key when using shifted special keys
6903 cmd when using "v", "V" or CTRL-V
6904 See |Select-mode|.
6905 The 'selectmode' option is set by the |:behave| command.
6906
6907 *'sessionoptions'* *'ssop'*
6908'sessionoptions' 'ssop' string (default: "blank,buffers,curdir,folds,

6914 separated list of words. Each word enables saving and restoring
6915 something:
6916 word save and restore ~
6917 blank empty windows

Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01006949 When neither "curdir" nor "sesdir" is included, file names are stored
6950 with absolute paths.
Bram Moolenaar2f0936c2022-01-08 21:51:59 +00006951 If you leave out "options" many things won't work well after restoring
6952 the session.
Bram Moolenaar071d4272004-06-13 20:20:40 +00006953 "slash" and "unix" are useful on Windows when sharing session files
6954 with Unix. The Unix version of Vim cannot source dos format scripts,
6955 but the Windows version of Vim can source unix format scripts.

6957 *'shell'* *'sh'* *E91*
Bram Moolenaar95a9dd12019-12-19 22:12:03 +01006958'shell' 'sh' string (default $SHELL or "sh", Win32: "cmd.exe")
Bram Moolenaar071d4272004-06-13 20:20:40 +00006959 global
6960 Name of the shell to use for ! and :! commands. When changing the
6961 value also check these options: 'shelltype', 'shellpipe', 'shellslash'
6962 'shellredir', 'shellquote', 'shellxquote' and 'shellcmdflag'.
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00006963 It is allowed to give an argument to the command, e.g. "csh -f".
Bram Moolenaar071d4272004-06-13 20:20:40 +00006964 See |option-backslash| about including spaces and backslashes.
6965 Environment variables are expanded |:set_env|.
Bram Moolenaar4bfa8af2018-02-03 15:14:46 +01006966
Bram Moolenaara2baa732022-02-04 16:09:54 +00006967 In |restricted-mode| shell commands will not be possible. This mode
6968 is used if the value of $SHELL ends in "false" or "nologin".
6969
Bram Moolenaar1ff14ba2019-11-02 14:09:23 +01006970 If the name of the shell contains a space, you need to enclose it in
Bram Moolenaar5ef1c6a2019-11-10 22:09:11 +01006971 quotes and escape the space. Example with quotes: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00006972 :set shell=\"c:\program\ files\unix\sh.exe\"\ -f
6973< Note the backslash before each quote (to avoid starting a comment) and
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00006974 each space (to avoid ending the option value). Also note that the
Bram Moolenaar071d4272004-06-13 20:20:40 +00006975 "-f" is not inside the quotes, because it is not part of the command
Bram Moolenaar4bfa8af2018-02-03 15:14:46 +01006976 name. Vim automagically recognizes the backslashes that are path
Bram Moolenaar071d4272004-06-13 20:20:40 +00006977 separators.
Bram Moolenaar4bfa8af2018-02-03 15:14:46 +01006978 Example with escaped space (Vim will do this when initializing the
6979 option from $SHELL): >
6980 :set shell=/bin/with\\\ space/sh
Bram Moolenaard473c8c2018-08-11 18:00:22 +02006981< The resulting value of 'shell' is "/bin/with\ space/sh", two
Bram Moolenaar4bfa8af2018-02-03 15:14:46 +01006982 backslashes are consumed by `:set`.
6983
Bram Moolenaar071d4272004-06-13 20:20:40 +00006984 Under MS-Windows, when the executable ends in ".com" it must be
6985 included. Thus setting the shell to "command.com" or "4dos.com"
6986 works, but "command" and "4dos" do not work for all commands (e.g.,
6987 filtering).
6988 For unknown reasons, when using "4dos.com" the current directory is
6989 changed to "C:\". To avoid this set 'shell' like this: >
6990 :set shell=command.com\ /c\ 4dos
6991< This option cannot be set from a |modeline| or in the |sandbox|, for
6992 security reasons.

7002 For MS-Windows, the default is set according to the value of 'shell',
7003 to reduce the need to set this option by the user.
Bram Moolenaar5302d9e2011-09-14 17:55:08 +02007004 On Unix it can have more than one flag. Each white space separated
7005 part is passed as an argument to the shell command.

7021 The name of the temporary file can be represented by "%s" if necessary
7022 (the file name is appended automatically if no %s appears in the value
7023 of this option).
Mike Williams12795022021-06-28 20:53:58 +02007024 For the Amiga the default is ">". For MS-Windows using powershell the
7025 default is "2>&1 | Out-File -Encoding default", otherwise the default
7026 is ">%s 2>&1". The output is directly saved in a file and not echoed
7027 to the screen.
Bram Moolenaar1c6737b2020-09-07 22:18:52 +02007028 For Unix the default is "| tee". The stdout of the compiler is saved

Natanael Copa56318362021-05-06 18:46:35 +02007032 "bash", "fish", "ash" or "dash" the default becomes "2>&1| tee". This
7033 means that stderr is also included. Before using the 'shell' option a
7034 path is removed, thus "/bin/sh" uses "sh".
Mike Williamsa3d1b292021-06-30 20:56:00 +02007035 For Unix and MS-Windows, when the 'shell' option is "pwsh" the default
7036 becomes ">%s 2>&1" and the output is not echoed to the screen.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007037 The initialization of this option is done after reading the ".vimrc"
7038 and the other initializations, so that when the 'shell' option is set
7039 there, the 'shellpipe' option changes automatically, unless it was
7040 explicitly set before.
7041 When 'shellpipe' is set to an empty string, no redirection of the
7042 ":make" output will be done. This is useful if you use a 'makeprg'
7043 that writes to 'makeef' by itself. If you want no piping, but do
7044 want to include the 'makeef', set 'shellpipe' to a single space.
7045 Don't forget to precede the space with a backslash: ":set sp=\ ".
7046 In the future pipes may be used for filtering and this option will
7047 become obsolete (at least for Unix).
7048 This option cannot be set from a |modeline| or in the |sandbox|, for
7049 security reasons.

7055 the "!" and ":!" commands. The redirection is kept outside of the
7056 quoting. See 'shellxquote' to include the redirection. It's
7057 probably not useful to set both options.
7058 This is an empty string by default. Only known to be useful for
Bram Moolenaar5666fcd2019-12-26 14:35:26 +01007059 third-party shells on MS-Windows-like systems, such as the MKS Korn
Mike Williamsa3d1b292021-06-30 20:56:00 +02007060 Shell or bash, where it should be "\"". See |dos-shell|.

Bram Moolenaar071d4272004-06-13 20:20:40 +00007068 String to be used to put the output of a filter command in a temporary
7069 file. See also |:!|. See |option-backslash| about including spaces
7070 and backslashes.
7071 The name of the temporary file can be represented by "%s" if necessary
7072 (the file name is appended automatically if no %s appears in the value
7073 of this option).
Bram Moolenaar96f45c02019-10-26 19:53:45 +02007074 The default is ">". For Unix, if the 'shell' option is "csh" or
7075 "tcsh" during initializations, the default becomes ">&". If the
Bram Moolenaar0c0734d2019-11-26 21:44:46 +01007076 'shell' option is "sh", "ksh", "mksh", "pdksh", "zsh", "zsh-beta",
Mike Williamsa3d1b292021-06-30 20:56:00 +02007077 "bash", "fish", or "pwsh", the default becomes ">%s 2>&1". This means
7078 that stderr is also included. For Win32, the Unix checks are done and
Mike Williams12795022021-06-28 20:53:58 +02007079 additionally "cmd" is checked for, which makes the default ">%s 2>&1",
7080 and "powershell" is checked for which makes the default
Mike Williamsa3d1b292021-06-30 20:56:00 +02007081 "2>&1 | Out-File -Encoding default" (see |dos-powershell|). Also, the
7082 same names with ".exe" appended are checked for.

7094 global
Bram Moolenaar6f345a12019-12-17 21:27:18 +01007095 {only for MS-Windows}
Bram Moolenaar071d4272004-06-13 20:20:40 +00007096 When set, a forward slash is used when expanding file names. This is
Mike Williamsa3d1b292021-06-30 20:56:00 +02007097 useful when a Unix-like shell is used instead of cmd.exe, pwsh.exe, or
Mike Williams12795022021-06-28 20:53:58 +02007098 powershell.exe. Backward slashes can still be typed, but they are
7099 changed to forward slashes by Vim.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007100 Note that setting or resetting this option has no effect for some
7101 existing file names, thus this option needs to be set before opening
7102 any file for best results. This might change in the future.
7103 'shellslash' only works when a backslash can be used as a path
7104 separator. To test if this is so use: >
7105 if exists('+shellslash')
Bram Moolenaarac3150d2019-07-28 16:36:39 +02007106< Also see 'completeslash'.

7110 global
Bram Moolenaar26a60b42005-02-22 08:49:11 +00007111 When on, use temp files for shell commands. When off use a pipe.
7112 When using a pipe is not possible temp files are used anyway.
Bram Moolenaar97293012011-07-18 19:40:27 +02007113 Currently a pipe is only supported on Unix and MS-Windows 2K and
7114 later. You can check it with: >
Bram Moolenaar26a60b42005-02-22 08:49:11 +00007115 :if has("filterpipe")
7116< The advantage of using a pipe is that nobody can read the temp file
7117 and the 'shell' command does not need to support redirection.
7118 The advantage of using a temp file is that the file type and encoding
7119 can be detected.
7120 The |FilterReadPre|, |FilterReadPost| and |FilterWritePre|,
7121 |FilterWritePost| autocommands event are not triggered when
7122 'shelltemp' is off.
Bram Moolenaar269f5952016-07-15 22:54:41 +02007123 The `system()` function does not respect this option and always uses
7124 temp files.
Bram Moolenaar036986f2017-03-16 17:41:02 +01007125 NOTE: This option is set to the Vim default value when 'compatible'

7134 0 and 1: always use the shell
7135 2 and 3: use the shell only to filter lines
7136 4 and 5: use shell only for ':sh' command
7137 When not using the shell, the command is executed directly.

7320 pressed.
7321 The %S 'statusline' item can be used in 'statusline' or 'tabline' to

7332 required (coding style permitting).
Bram Moolenaar446cb832008-06-24 21:56:24 +00007333 Note that this doesn't work well together with having "longest" in

Bram Moolenaar482aaeb2005-09-29 18:26:07 +00007396 right of the cursor if 'nowrap' is set. Setting this option to a
7397 value greater than 0 while having |'sidescroll'| also at a non-zero
7398 value makes some context visible in the line you are scrolling in
7399 horizontally (except at beginning of the line). Setting this option
7400 to a large value (like 999) has the effect of keeping the cursor
7401 horizontally centered in the window, as long as one does not come too
7402 close to the beginning of the line.
Bram Moolenaar375e3392019-01-31 18:26:10 +01007403 After using the local value, go back the global value with one of

Bram Moolenaar071d4272004-06-13 20:20:40 +00007442 Do smart autoindenting when starting a new line. Works for C-like
7443 programs, but can also be used for other languages. 'cindent' does
7444 something like this, works better in most cases, but is more strict,
Bram Moolenaar81af9252010-12-10 20:35:50 +01007445 see |C-indenting|. When 'cindent' is on or 'indentexpr' is set,
Bram Moolenaar166af9b2010-11-16 20:34:40 +01007446 setting 'si' has no effect. 'indentexpr' is a more advanced
7447 alternative.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007448 Normally 'autoindent' should also be on when using 'smartindent'.
7449 An indent is automatically inserted:
7450 - After a line ending in '{'.
7451 - After a line starting with a keyword from 'cinwords'.
7452 - Before a line starting with '}' (only with the "O" command).
7453 When typing '}' as the first character in a new line, that line is
7454 given the same indent as the matching '{'.
7455 When typing '#' as the first character in a new line, the indent for
7456 that line is removed, the '#' is put in the first column. The indent
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00007457 is restored for the next line. If you don't want this, use this
Bram Moolenaar071d4272004-06-13 20:20:40 +00007458 mapping: ":inoremap # X^H#", where ^H is entered with CTRL-V CTRL-H.

7561 name if you want to. However, it will then only be used when
7562 'spellfile' is set to it, for entries in 'spelllang' only files
7563 without region name will be found.

Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01007572 A comma-separated list of word list names. When the 'spell' option is
Bram Moolenaar3b506942005-06-23 22:36:45 +00007573 on spellchecking will be done for these languages. Example: >
7574 set spelllang=en_us,nl,medical
7575< This means US English, Dutch and medical words are recognized. Words
7576 that are not recognized will be highlighted.
Bram Moolenaar911ead12019-04-21 00:03:35 +02007577 The word list name must consist of alphanumeric characters, a dash or
7578 an underscore. It should not include a comma or dot. Using a dash is
Bram Moolenaar3b506942005-06-23 22:36:45 +00007579 recommended to separate the two letter language name from a
7580 specification. Thus "en-rare" is used for rare English words.
7581 A region name must come last and have the form "_xx", where "xx" is
7582 the two-letter, lower case region name. You can use more than one
7583 region by listing them: "en_us,en_ca" supports both US and Canadian
7584 English, but not words specific for Australia, New Zealand or Great
Bram Moolenaarfa735342016-01-03 22:14:44 +01007585 Britain. (Note: currently en_au and en_nz dictionaries are older than
7586 en_ca, en_gb and en_us).
Bram Moolenaarcc63c642013-11-12 04:44:01 +01007587 If the name "cjk" is included East Asian characters are excluded from
7588 spell checking. This is useful when editing text that also has Asian
7589 words.
Bram Moolenaar6c391a72021-09-09 21:55:11 +02007590 Note that the "medical" dictionary does not exist, it is just an
7591 example of a longer name.

Bram Moolenaarce0842a2005-07-18 21:58:11 +00007593 As a special case the name of a .spl file can be given as-is. The
7594 first "_xx" in the name is removed and used as the region name
7595 (_xx is an underscore, two letters and followed by a non-letter).
7596 This is mainly for testing purposes. You must make sure the correct
7597 encoding is used, Vim doesn't check it.
Bram Moolenaar402d2fe2005-04-15 21:00:38 +00007598 When 'encoding' is set the word lists are reloaded. Thus it's a good
Bram Moolenaarce0842a2005-07-18 21:58:11 +00007599 idea to set 'spelllang' after setting 'encoding' to avoid loading the
7600 files twice.
Bram Moolenaar3b506942005-06-23 22:36:45 +00007601 How the related spell files are found is explained here: |spell-load|.

Bram Moolenaar98692072006-02-04 00:57:42 +00007603 If the |spellfile.vim| plugin is active and you use a language name
7604 for which Vim cannot find the .spl file in 'runtimepath' the plugin
7605 will ask you if you want to download the file.

Bram Moolenaar24bbcfe2005-06-28 23:32:02 +00007629 the |spellsuggest()| function. This is a comma-separated list of
7630 items:
Bram Moolenaard857f0e2005-06-21 22:37:39 +00007631
Bram Moolenaar24bbcfe2005-06-28 23:32:02 +00007632 best Internal method that works best for English. Finds
7633 changes like "fast" and uses a bit of sound-a-like
7634 scoring to improve the ordering.
7635
7636 double Internal method that uses two methods and mixes the
7637 results. The first method is "fast", the other method
Bram Moolenaard857f0e2005-06-21 22:37:39 +00007638 computes how much the suggestion sounds like the bad
Bram Moolenaar24bbcfe2005-06-28 23:32:02 +00007639 word. That only works when the language specifies
7640 sound folding. Can be slow and doesn't always give
7641 better results.
7642
7643 fast Internal method that only checks for simple changes:
7644 character inserts/deletes/swaps. Works well for
7645 simple typing mistakes.
7646
Bram Moolenaar2c7a29c2005-12-12 22:02:31 +00007647 {number} The maximum number of suggestions listed for |z=|.
Bram Moolenaar8aff23a2005-08-19 20:40:30 +00007648 Not used for |spellsuggest()|. The number of
7649 suggestions is never more than the value of 'lines'
7650 minus two.
7651
Bram Moolenaar585ee072022-01-29 11:22:17 +00007652 timeout:{millisec} Limit the time searching for suggestions to
7653 {millisec} milli seconds. Applies to the following
7654 methods. When omitted the limit is 5000. When
7655 negative there is no limit. {only works when built
Bram Moolenaar8a3b8052022-06-26 12:21:15 +01007656 with the |+reltime| feature}

Bram Moolenaar24bbcfe2005-06-28 23:32:02 +00007658 file:{filename} Read file {filename}, which must have two columns,
7659 separated by a slash. The first column contains the
7660 bad word, the second column the suggested good word.
7661 Example:
7662 theribal/terrible ~
7663 Use this for common mistakes that do not appear at the
7664 top of the suggestion list with the internal methods.
7665 Lines without a slash are ignored, use this for
7666 comments.
Bram Moolenaarbcb98982014-05-01 14:08:19 +02007667 The word in the second column must be correct,
7668 otherwise it will not be used. Add the word to an
7669 ".add" file if it is currently flagged as a spelling
7670 mistake.
Bram Moolenaar24bbcfe2005-06-28 23:32:02 +00007671 The file is used for all languages.
7672
7673 expr:{expr} Evaluate expression {expr}. Use a function to avoid
Bram Moolenaara4e0b972022-10-01 19:43:52 +01007674 trouble with spaces. Best is to call a function
7675 without arguments, see |expr-option-function|.
7676 |v:val| holds the badly spelled word. The expression
7677 must evaluate to a List of Lists, each with a
7678 suggestion and a score.
Bram Moolenaar24bbcfe2005-06-28 23:32:02 +00007679 Example:
Bram Moolenaar214641f2017-03-05 17:04:09 +01007680 [['the', 33], ['that', 44]] ~
Bram Moolenaar2c7a29c2005-12-12 22:02:31 +00007681 Set 'verbose' and use |z=| to see the scores that the
Bram Moolenaar24bbcfe2005-06-28 23:32:02 +00007682 internal methods use. A lower score is better.
7683 This may invoke |spellsuggest()| if you temporarily
7684 set 'spellsuggest' to exclude the "expr:" part.
7685 Errors are silently ignored, unless you set the
7686 'verbose' option to a non-zero value.
7687
7688 Only one of "best", "double" or "fast" may be used. The others may
7689 appear several times in any order. Example: >
7690 :set sps=file:~/.vim/sugg,best,expr:MySuggest()
7691<
7692 This option cannot be set from a |modeline| or in the |sandbox|, for

7745
7746 The option consists of printf style '%' items interspersed with

7748 %-0{minwid}.{maxwid}{item}
Bram Moolenaar5e9b2fa2016-02-01 22:37:05 +01007749 All fields except the {item} are optional. A single percent sign can
Bram Moolenaar8133cc62020-10-26 21:05:27 +01007750 be given as "%%".
Bram Moolenaar071d4272004-06-13 20:20:40 +00007751
Bram Moolenaar238a5642006-02-21 22:12:05 +00007752 When the option starts with "%!" then it is used as an expression,
7753 evaluated and the result is used as the option value. Example: >

7757 The result can contain %{} items that will be evaluated too.
Bram Moolenaar61d35bd2012-03-28 20:51:51 +02007758 Note that the "%!" expression is evaluated in the context of the
7759 current window and buffer, while %{} items are evaluated in the
7760 context of the window that the statusline belongs to.
Bram Moolenaar238a5642006-02-21 22:12:05 +00007761
7762 When there is error while evaluating the option then it will be made
7763 empty to avoid further errors. Otherwise screen updating would loop.
Bram Moolenaar1b5f03e2023-01-09 20:12:45 +00007764 When the result contains unprintable characters the result is
7765 unpredictable.

Bram Moolenaare37d50a2008-08-06 17:06:04 +00007869 When displaying a flag, Vim removes the leading comma, if any, when
7870 that flag comes right after plaintext. This will make a nice display
7871 when flags are used like in the examples below.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007872
Bram Moolenaar582fd852005-03-28 20:58:01 +00007873 When all items in a group becomes an empty string (i.e. flags that are
Bram Moolenaar071d4272004-06-13 20:20:40 +00007874 not set) and a minwid is not set for the group, the whole group will
7875 become empty. This will make a group like the following disappear
7876 completely from the statusline when none of the flags are set. >

Bram Moolenaar30b65812012-07-12 22:01:11 +02007888 The 'statusline' option will be evaluated in the |sandbox| if set from
7889 a modeline, see |sandbox-option|.
Bram Moolenaar110289e2019-05-23 15:38:06 +02007890 This option cannot be set in a modeline when 'modelineexpr' is off.
Bram Moolenaarb71eaae2006-01-20 23:10:18 +00007891
7892 It is not allowed to change text or jump to another window while
7893 evaluating 'statusline' |textlock|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007894
7895 If the statusline is not updated when you want it (e.g., after setting
7896 a variable that's used in an expression), you can force an update by
Bram Moolenaarcfa8f9a2022-06-03 21:59:47 +01007897 using `:redrawstatus`.

Bram Moolenaarcfa8f9a2022-06-03 21:59:47 +01007899 A result of all digits is regarded a number for display purposes.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007900 Otherwise the result is taken as flag text and applied to the rules
7901 described above.

Bram Moolenaarcd71fa32005-03-11 22:46:48 +00007903 Watch out for errors in expressions. They may render Vim unusable!
Bram Moolenaar071d4272004-06-13 20:20:40 +00007904 If you are stuck, hold down ':' or 'Q' to get a prompt, then quit and
Bram Moolenaarc4da1132017-07-15 19:39:43 +02007905 edit your .vimrc or whatever with "vim --clean" to get it right.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007906

Bram Moolenaar071d4272004-06-13 20:20:40 +00007929 Files with these suffixes get a lower priority when multiple files
7930 match a wildcard. See |suffixes|. Commas can be used to separate the
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00007931 suffixes. Spaces after the comma are ignored. A dot is also seen as
7932 the start of a suffix. To avoid a dot or comma being recognized as a
Bram Moolenaar071d4272004-06-13 20:20:40 +00007933 separator, precede it with a backslash (see |option-backslash| about
7934 including spaces and backslashes).
7935 See 'wildignore' for completely ignoring files.
7936 The use of |:set+=| and |:set-=| is preferred when adding or removing
7937 suffixes from the list. This avoids problems when a future version
7938 uses another default.

Bram Moolenaar071d4272004-06-13 20:20:40 +00007951 swapfile is not wanted for a specific buffer. For example, with
7952 confidential information that even root must not be able to access.
7953 Careful: All text will be in memory:
7954 - Don't use this for big files.
7955 - Recovery will be impossible!
7956 A swapfile will only be present when |'updatecount'| is non-zero and
7957 'swapfile' is set.
7958 When 'swapfile' is reset, the swap file for the current buffer is
7959 immediately deleted. When 'swapfile' is set, and 'updatecount' is
7960 non-zero, a swap file is immediately created.
7961 Also see |swap-file| and |'swapsync'|.
Bram Moolenaar76f3b1a2014-03-27 22:30:07 +01007962 If you want to open a new buffer without creating a swap file for it,
7963 use the |:noswapfile| modifier.
Bram Moolenaar22f1d0e2018-02-27 14:53:30 +01007964 See 'directory' for where the swap file is created.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007965

Bram Moolenaar071d4272004-06-13 20:20:40 +00007972 When this option is not empty a swap file is synced to disk after
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00007973 writing to it. This takes some time, especially on busy unix systems.
Bram Moolenaar071d4272004-06-13 20:20:40 +00007974 When this option is empty parts of the swap file may be in memory and
7975 not written to disk. When the system crashes you may lose more work.
7976 On Unix the system does a sync now and then without Vim asking for it,
7977 so the disadvantage of setting this option off is small. On some
7978 systems the swap file will not be written at all. For a unix system
7979 setting it to "sync" will use the sync() call instead of the default
7980 fsync(), which may work better on some systems.
Bram Moolenaar293ee4d2004-12-09 21:34:53 +00007981 The 'fsync' option is used for the actual file.

Bram Moolenaar63b74a82019-03-24 15:09:13 +01008003 Otherwise: do not split, use current window (when used
8004 in the quickfix window: the previously used window or
8005 split if there is no other window).
Bram Moolenaara594d772015-06-19 14:41:49 +02008006 vsplit Just like "split" but split vertically.

8030 syntax highlighting has been switched off with ":syntax off".
8031 Otherwise this option does not always reflect the current syntax (the
8032 b:current_syntax variable does).
8033 This option is most useful in a modeline, for a file which syntax is
Bram Moolenaar97b2ad32006-03-18 21:40:56 +00008034 not automatically recognized. Example, in an IDL file:
8035 /* vim: set syntax=idl : */ ~
8036 When a dot appears in the value then this separates two filetype
8037 names. Example:
8038 /* vim: set syntax=c.doxygen : */ ~
8039 This will use the "c" syntax first, then the "doxygen" syntax.
8040 Note that the second one must be prepared to be loaded as an addition,
8041 otherwise it will be skipped. More than one dot may appear.
8042 To switch off syntax highlighting for the current file, use: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00008043 :set syntax=OFF
8044< To switch syntax highlighting on according to the current value of the

Bram Moolenaar5c8837f2006-02-25 21:52:33 +00008061 option and only when there is no GUI tab line. When 'e' is in
8062 'guioptions' and the GUI supports a tab line 'guitablabel' is used
Bram Moolenaar7f036442010-08-15 15:24:20 +02008063 instead. Note that the two tab pages lines are very different.
Bram Moolenaarfaa959a2006-02-20 21:37:40 +00008064
8065 The value is evaluated like with 'statusline'. You can use

8086 Number of spaces that a <Tab> in the file counts for. Also see
Bram Moolenaarf10911e2022-01-29 22:20:48 +00008087 the |:retab| command, and the 'softtabstop' option.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008088
8089 Note: Setting 'tabstop' to any other value than 8 can make your file
Bram Moolenaarf10911e2022-01-29 22:20:48 +00008090 appear wrong in many places, e.g., when printing it.
8091 The value must be more than 0 and less than 10000.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008092
8093 There are four main ways to use tabs in Vim:
8094 1. Always keep 'tabstop' at 8, set 'softtabstop' and 'shiftwidth' to 4
8095 (or 3 or whatever you prefer) and use 'noexpandtab'. Then Vim
Bram Moolenaarebcbd022007-05-12 14:28:25 +00008096 will use a mix of tabs and spaces, but typing <Tab> and <BS> will
Bram Moolenaar071d4272004-06-13 20:20:40 +00008097 behave like a tab appears every 4 (or 3) characters.
Bram Moolenaar10e8ff92023-06-10 21:40:39 +01008098 This is the recommended way, the file will look the same with other
8099 tools and when listing it in a terminal.
8100 2. Set 'softtabstop' and 'shiftwidth' to whatever you prefer and use
8101 'expandtab'. This way you will always insert spaces. The
8102 formatting will never be messed up when 'tabstop' is changed (leave
8103 it at 8 just in case). The file will be a bit larger.
8104 You do need to check if no Tabs exist in the file. You can get rid
8105 of them by first setting 'expandtab' and using `%retab!`, making
8106 sure the value of 'tabstop' is set correctly.
8107 3. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use
Bram Moolenaar071d4272004-06-13 20:20:40 +00008108 'expandtab'. This way you will always insert spaces. The
8109 formatting will never be messed up when 'tabstop' is changed.
Bram Moolenaar10e8ff92023-06-10 21:40:39 +01008110 You do need to check if no Tabs exist in the file, just like in the
8111 item just above.
8112 4. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use a
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00008113 |modeline| to set these values when editing the file again. Only
Bram Moolenaar10e8ff92023-06-10 21:40:39 +01008114 works when using Vim to edit the file, other tools assume a tabstop
8115 is worth 8 spaces.
8116 5. Always set 'tabstop' and 'shiftwidth' to the same value, and
Bram Moolenaar071d4272004-06-13 20:20:40 +00008117 'noexpandtab'. This should then work (for initial indents only)
8118 for any tabstop setting that people use. It might be nice to have
8119 tabs after the first non-blank inserted as spaces if you do this
8120 though. Otherwise aligned comments will be wrong when 'tabstop' is
8121 changed.
8122
Bram Moolenaar04958cb2018-06-23 19:23:02 +02008123 If Vim is compiled with the |+vartabs| feature then the value of
8124 'tabstop' will be ignored if |'vartabstop'| is set to anything other
8125 than an empty string.

8129 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00008130 When searching for a tag (e.g., for the |:ta| command), Vim can either
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00008131 use a binary search or a linear search in a tags file. Binary
Bram Moolenaar071d4272004-06-13 20:20:40 +00008132 searching makes searching for a tag a LOT faster, but a linear search
8133 will find more tags if the tags file wasn't properly sorted.
8134 Vim normally assumes that your tags files are sorted, or indicate that
8135 they are not sorted. Only when this is not the case does the
8136 'tagbsearch' option need to be switched off.
8137
8138 When 'tagbsearch' is on, binary searching is first used in the tags
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00008139 files. In certain situations, Vim will do a linear search instead for
Bram Moolenaar071d4272004-06-13 20:20:40 +00008140 certain files, or retry all files with a linear search. When
8141 'tagbsearch' is off, only a linear search is done.
8142
8143 Linear searching is done anyway, for one file, when Vim finds a line
8144 at the start of the file indicating that it's not sorted: >
Bram Moolenaar446cb832008-06-24 21:56:24 +00008145 !_TAG_FILE_SORTED 0 /some comment/
Bram Moolenaar071d4272004-06-13 20:20:40 +00008146< [The whitespace before and after the '0' must be a single <Tab>]
8147
8148 When a binary search was done and no match was found in any of the
Bram Moolenaar0f6562e2015-11-24 18:48:14 +01008149 files listed in 'tags', and case is ignored or a pattern is used
Bram Moolenaar071d4272004-06-13 20:20:40 +00008150 instead of a normal tag name, a retry is done with a linear search.
8151 Tags in unsorted tags files, and matches with different case will only
8152 be found in the retry.
8153
Bram Moolenaard4755bb2004-09-02 19:12:26 +00008154 If a tag file indicates that it is case-fold sorted, the second,
Bram Moolenaar0f6562e2015-11-24 18:48:14 +01008155 linear search can be avoided when case is ignored. Use a value of '2'
8156 in the "!_TAG_FILE_SORTED" line for this. A tag file can be case-fold
8157 sorted with the -f switch to "sort" in most unices, as in the command:
Bram Moolenaar47c532e2022-03-19 15:18:53 +00008158 "sort -f -o tags tags". For Universal ctags and Exuberant ctags
8159 version 5.x or higher (at least 5.5) the --sort=foldcase switch can be
8160 used for this as well. Note that case must be folded to uppercase for
8161 this to work.
Bram Moolenaar0f6562e2015-11-24 18:48:14 +01008162
8163 By default, tag searches are case-sensitive. Case is ignored when
8164 'ignorecase' is set and 'tagcase' is "followic", or when 'tagcase' is
8165 "ignore".
Bram Moolenaar66e29d72016-08-20 16:57:02 +02008166 Also when 'tagcase' is "followscs" and 'smartcase' is set, or
8167 'tagcase' is "smart", and the pattern contains only lowercase
8168 characters.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008169
8170 When 'tagbsearch' is off, tags searching is slower when a full match
8171 exists, but faster when no full match exists. Tags in unsorted tags
8172 files may only be found with 'tagbsearch' off.
8173 When the tags file is not sorted, or sorted in a wrong way (not on
8174 ASCII byte value), 'tagbsearch' should be off, or the line given above
8175 must be included in the tags file.
8176 This option doesn't affect commands that find all matching tags (e.g.,
8177 command-line completion and ":help").

Bram Moolenaar071d4272004-06-13 20:20:40 +00008226 When a file name starts with "./", the '.' is replaced with the path
8227 of the current file. But only when the 'd' flag is not included in
8228 'cpoptions'. Environment variables are expanded |:set_env|. Also see
8229 |tags-option|.
8230 "*", "**" and other wildcards can be used to search for tags files in
Bram Moolenaare2b590e2010-08-08 18:29:48 +02008231 a directory tree. See |file-searching|. E.g., "/lib/**/tags" will
8232 find all files named "tags" below "/lib". The filename itself cannot
8233 contain wildcards, it is used as-is. E.g., "/lib/**/tags?" will find
Bram Moolenaar2bd9dbc2022-08-25 18:12:06 +01008234 files called "tags?".
Bram Moolenaare7eb9df2005-09-09 19:49:30 +00008235 The |tagfiles()| function can be used to get a list of the file names
8236 actually used.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008237 If Vim was compiled with the |+emacs_tags| feature, Emacs-style tag
8238 files are also supported. They are automatically recognized. The
8239 default value becomes "./tags,./TAGS,tags,TAGS", unless case
8240 differences are ignored (MS-Windows). |emacs-tags|
8241 The use of |:set+=| and |:set-=| is preferred when adding or removing
8242 file names from the list. This avoids problems when a future version
8243 uses another default.

8249 ":tselect" command with an argument will not push the tag onto the
8250 tagstack. A following ":tag" without an argument, a ":pop" command or
8251 any other command that uses the tagstack will use the unmodified
8252 tagstack, but does change the pointer to the active entry.
8253 Resetting this option is useful when using a ":tag" command in a

8310 message is shown.
Bram Moolenaarac360bf2015-09-01 20:31:20 +02008311 For the Win32 GUI and console versions 'termencoding' is not used,
Bram Moolenaar071d4272004-06-13 20:20:40 +00008312 because the Win32 system always passes Unicode characters.
8313 When empty, the same encoding is used as for the 'encoding' option.
8314 This is the normal value.
8315 Not all combinations for 'termencoding' and 'encoding' are valid. See
8316 |encoding-table|.
8317 The value for this option must be supported by internal conversions or
8318 iconv(). When this is not possible no conversion will be done and you
8319 will probably experience problems with non-ASCII characters.

8381 {rows}x{columns} or {rows}*{columns}.
Bram Moolenaar74675a62017-07-15 13:53:23 +02008382 - When empty the terminal gets the size from the window.
Bram Moolenaar498c2562018-04-15 23:45:15 +02008383 - When set with a "x" (e.g., "24x80") the terminal size is not
8384 adjusted to the window size. If the window is smaller only the
8385 top-left part is displayed.
8386 - When set with a "*" (e.g., "10*50") the terminal size follows the
8387 window size, but will not be smaller than the specified rows and/or
8388 columns.
8389 - When rows is zero then use the height of the window.
8390 - When columns is zero then use the width of the window.
8391 - Using "0x0" or "0*0" is the same as empty.
Bram Moolenaar1c6737b2020-09-07 22:18:52 +02008392 - Can be overruled in the |term_start()| options with "term_rows" and
8393 "term_cols".
Bram Moolenaar498c2562018-04-15 23:45:15 +02008394
8395 Examples:
8396 "30x0" uses 30 rows and the current window width.
8397 "20*0" uses at least 20 rows and the current window width.
8398 "0*40" uses the current window height and at least 40 columns.
Bram Moolenaar1f2903c2017-07-23 19:51:01 +02008399 Note that the command running in the terminal window may still change
8400 the size of the terminal. In that case the Vim window will be
8401 adjusted to that size, if possible.

Bram Moolenaar94237492017-04-23 18:40:21 +02008504'ttimeout' boolean (default off, set in |defaults.vim|)
Bram Moolenaar071d4272004-06-13 20:20:40 +00008505 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00008506 These two options together determine the behavior when part of a
8507 mapped key sequence or keyboard code has been received:
8508
8509 'timeout' 'ttimeout' action ~
8510 off off do not time out
8511 on on or off time out on :mappings and key codes
8512 off on time out on key codes
8513
8514 If both options are off, Vim will wait until either the complete
8515 mapping or key sequence has been received, or it is clear that there
8516 is no mapping or key sequence for the received characters. For
8517 example: if you have mapped "vl" and Vim has received 'v', the next
8518 character is needed to see if the 'v' is followed by an 'l'.
8519 When one of the options is on, Vim will wait for about 1 second for
8520 the next character to arrive. After that the already received
8521 characters are interpreted as single characters. The waiting time can
8522 be changed with the 'timeoutlen' option.
8523 On slow terminals or very busy systems timing out may cause
8524 malfunctioning cursor keys. If both options are off, Vim waits
8525 forever after an entered <Esc> if there are key codes that start
8526 with <Esc>. You will have to type <Esc> twice. If you do not have
8527 problems with key codes, but would like to have :mapped key
8528 sequences not timing out in 1 second, set the 'ttimeout' option and
8529 reset the 'timeout' option.
8530
8531 NOTE: 'ttimeout' is reset when 'compatible' is set.

Bram Moolenaar94237492017-04-23 18:40:21 +02008538'ttimeoutlen' 'ttm' number (default -1, set to 100 in |defaults.vim|)
Bram Moolenaar071d4272004-06-13 20:20:40 +00008539 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00008540 The time in milliseconds that is waited for a key code or mapped key
8541 sequence to complete. Also used for CTRL-\ CTRL-N and CTRL-\ CTRL-G
8542 when part of a command has been typed.
8543 Normally only 'timeoutlen' is used and 'ttimeoutlen' is -1. When a
8544 different timeout value for key codes is desired set 'ttimeoutlen' to
8545 a non-negative number.
8546
8547 ttimeoutlen mapping delay key code delay ~
8548 < 0 'timeoutlen' 'timeoutlen'
8549 >= 0 'timeoutlen' 'ttimeoutlen'
8550
8551 The timeout only happens when the 'timeout' and 'ttimeout' options
8552 tell so. A useful setting would be >
8553 :set timeout timeoutlen=3000 ttimeoutlen=100
8554< (time out on mapping after three seconds, time out on key codes after
8555 a tenth of a second).
8556
8557 *'title'* *'notitle'*
8558'title' boolean (default off, on when title can be restored)
8559 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00008560 When on, the title of the window will be set to the value of
8561 'titlestring' (if it is not empty), or to:
8562 filename [+=-] (path) - VIM
8563 Where:
8564 filename the name of the file being edited
8565 - indicates the file cannot be modified, 'ma' off
8566 + indicates the file was modified
8567 = indicates the file is read-only
8568 =+ indicates the file is read-only and modified
8569 (path) is the path of the file being edited
8570 - VIM the server name |v:servername| or "VIM"
8571 Only works if the terminal supports setting window titles
8572 (currently Amiga console, Win32 console, all GUI versions and
Bram Moolenaard1caa942020-04-10 22:10:56 +02008573 terminals with a non-empty 't_ts' option - these are Unix xterm and
Bram Moolenaar071d4272004-06-13 20:20:40 +00008574 iris-ansi by default, where 't_ts' is taken from the builtin termcap).
8575 *X11*
8576 When Vim was compiled with HAVE_X11 defined, the original title will
8577 be restored if possible. The output of ":version" will include "+X11"
8578 when HAVE_X11 was defined, otherwise it will be "-X11". This also
8579 works for the icon name |'icon'|.
8580 But: When Vim was started with the |-X| argument, restoring the title
8581 will not work (except in the GUI).
8582 If the title cannot be restored, it is set to the value of 'titleold'.
8583 You might want to restore the title outside of Vim then.
8584 When using an xterm from a remote machine you can use this command:
8585 rsh machine_name xterm -display $DISPLAY &
8586 then the WINDOWID environment variable should be inherited and the
8587 title of the window should change back to what it should be after
8588 exiting Vim.
8589
8590 *'titlelen'*
8591'titlelen' number (default 85)
8592 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00008593 Gives the percentage of 'columns' to use for the length of the window
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00008594 title. When the title is longer, only the end of the path name is
8595 shown. A '<' character before the path name is used to indicate this.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008596 Using a percentage makes this adapt to the width of the window. But
8597 it won't work perfectly, because the actual number of characters
8598 available also depends on the font used and other things in the title
8599 bar. When 'titlelen' is zero the full path is used. Otherwise,
8600 values from 1 to 30000 percent can be used.
8601 'titlelen' is also used for the 'titlestring' option.
8602
8603 *'titleold'*
8604'titleold' string (default "Thanks for flying Vim")
8605 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00008606 This option will be used for the window title when exiting Vim if the

8613 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00008614 When this option is not empty, it will be used for the title of the
8615 window. This happens only when the 'title' option is on.
8616 Only works if the terminal supports setting window titles (currently
8617 Amiga console, Win32 console, all GUI versions and terminals with a
8618 non-empty 't_ts' option).
8619 When Vim was compiled with HAVE_X11 defined, the original title will
Bram Moolenaar51628222016-12-01 23:03:28 +01008620 be restored if possible, see |X11|.

8630 of the available space.
8631 Some people prefer to have the file name first: >
8632 :set titlestring=%t%(\ %M%)%(\ (%{expand(\"%:~:.:h\")})%)%(\ %a%)
8633< Note the use of "%{ }" and an expression to get the path of the file,
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00008634 without the file name. The "%( %)" constructs are used to add a

Bram Moolenaar071d4272004-06-13 20:20:40 +00008650 tooltips Tooltips are active for toolbar buttons.
8651 Tooltips refer to the popup help text which appears after the mouse
8652 cursor is placed over a toolbar button for a brief moment.
8653
8654 If you want the toolbar to be shown with icons as well as text, do the
8655 following: >
8656 :set tb=icons,text
Bram Moolenaarcbaff5e2022-04-08 17:45:08 +01008657< Motif cannot display icons and text at the same time. They
Bram Moolenaar071d4272004-06-13 20:20:40 +00008658 will show icons if both are requested.
8659
8660 If none of the strings specified in 'toolbar' are valid or if
8661 'toolbar' is empty, this option is ignored. If you want to disable
8662 the toolbar, you need to set the 'guioptions' option. For example: >
8663 :set guioptions-=T
8664< Also see |gui-toolbar|.
8665
8666 *'toolbariconsize'* *'tbis'*
8667'toolbariconsize' 'tbis' string (default "small")
8668 global
Bram Moolenaar3df01732017-02-17 22:47:16 +01008669 {only in the GTK+ GUI}
Bram Moolenaar071d4272004-06-13 20:20:40 +00008670 Controls the size of toolbar icons. The possible values are:
Bram Moolenaar77cdfd12016-03-12 12:57:59 +01008671 tiny Use tiny icons.
8672 small Use small icons (default).
8673 medium Use medium-sized icons.
8674 large Use large icons.
8675 huge Use even larger icons.
8676 giant Use very big icons.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008677 The exact dimensions in pixels of the various icon sizes depend on
Bram Moolenaar77cdfd12016-03-12 12:57:59 +01008678 the current theme. Common dimensions are giant=48x48, huge=32x32,
8679 large=24x24, medium=24x24, small=20x20 and tiny=16x16.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008680
8681 If 'toolbariconsize' is empty, the global default size as determined
8682 by user preferences or the current theme is used.
8683
8684 *'ttybuiltin'* *'tbi'* *'nottybuiltin'* *'notbi'*
8685'ttybuiltin' 'tbi' boolean (default on)
8686 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00008687 When on, the builtin termcaps are searched before the external ones.
8688 When off the builtin termcaps are searched after the external ones.
8689 When this option is changed, you should set the 'term' option next for
8690 the change to take effect, for example: >
8691 :set notbi term=$TERM
8692< See also |termcap|.
8693 Rationale: The default for this option is "on", because the builtin
8694 termcap entries are generally better (many systems contain faulty
8695 xterm entries...).
8696
8697 *'ttyfast'* *'tf'* *'nottyfast'* *'notf'*
Bram Moolenaarc1cf4c92022-11-25 15:09:35 +00008698'ttyfast' 'tf' boolean (default on)

Bram Moolenaar071d4272004-06-13 20:20:40 +00008700 Indicates a fast terminal connection. More characters will be sent to
8701 the screen for redrawing, instead of using insert/delete line
8702 commands. Improves smoothness of redrawing when there are multiple
8703 windows and the terminal does not support a scrolling region.
8704 Also enables the extra writing of characters at the end of each screen
8705 line for lines that wrap. This helps when using copy/paste with the
8706 mouse in an xterm and other terminals.
8707
Bram Moolenaarc1cf4c92022-11-25 15:09:35 +00008708 The default used to be set only for some terminal names, but these
8709 days nearly all terminals are fast, therefore the default is now "on".
8710 If you have a slow connection you may want to set this option off,
8711 e.g. depending on the host name: >
8712 if hostname() =~ 'faraway'
8713 set nottyfast
8714 endif

8721 Name of the terminal type for which mouse codes are to be recognized.
Bram Moolenaar2c7a7632007-05-10 18:19:11 +00008722 Currently these strings are valid:
Bram Moolenaar071d4272004-06-13 20:20:40 +00008723 *xterm-mouse*
8724 xterm xterm-like mouse handling. The mouse generates
8725 "<Esc>[Mscr", where "scr" is three bytes:
8726 "s" = button state
8727 "c" = column plus 33
8728 "r" = row plus 33
Bram Moolenaare968e362014-05-13 20:23:24 +02008729 This only works up to 223 columns! See "dec",
8730 "urxvt", and "sgr" for solutions.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008731 xterm2 Works like "xterm", but with the xterm reporting the
8732 mouse position while the mouse is dragged. This works
8733 much faster and more precise. Your xterm must at
Bram Moolenaarbc7aa852005-03-06 23:38:09 +00008734 least at patchlevel 88 / XFree 3.3.3 for this to
Bram Moolenaar071d4272004-06-13 20:20:40 +00008735 work. See below for how Vim detects this
8736 automatically.
8737 *netterm-mouse*
Bram Moolenaar25c9c682019-05-05 18:13:34 +02008738 netterm NetTerm mouse handling. A left mouse click generates
Bram Moolenaar071d4272004-06-13 20:20:40 +00008739 "<Esc>}r,c<CR>", where "r,c" are two decimal numbers
Bram Moolenaar25c9c682019-05-05 18:13:34 +02008740 for the row and column. No other mouse events are
8741 supported.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008742 *dec-mouse*
8743 dec DEC terminal mouse handling. The mouse generates a
8744 rather complex sequence, starting with "<Esc>[".
Bram Moolenaare4efc3b2005-03-07 23:16:51 +00008745 This is also available for an Xterm, if it was
8746 configured with "--enable-dec-locator".
Bram Moolenaar071d4272004-06-13 20:20:40 +00008747 *jsbterm-mouse*
8748 jsbterm JSB term mouse handling.
8749 *pterm-mouse*
8750 pterm QNX pterm mouse handling.
Bram Moolenaarf1568ec2011-12-14 21:17:39 +01008751 *urxvt-mouse*
8752 urxvt Mouse handling for the urxvt (rxvt-unicode) terminal.
Bram Moolenaare968e362014-05-13 20:23:24 +02008753 The mouse works only if the terminal supports this
8754 encoding style, but it does not have 223 columns limit
8755 unlike "xterm" or "xterm2".
Bram Moolenaar9b451252012-08-15 17:43:31 +02008756 *sgr-mouse*
8757 sgr Mouse handling for the terminal that emits SGR-styled
Bram Moolenaare968e362014-05-13 20:23:24 +02008758 mouse reporting. The mouse works even in columns
8759 beyond 223. This option is backward compatible with
8760 "xterm2" because it can also decode "xterm2" style
8761 mouse codes.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008762
8763 The mouse handling must be enabled at compile time |+mouse_xterm|
Bram Moolenaare968e362014-05-13 20:23:24 +02008764 |+mouse_dec| |+mouse_netterm| |+mouse_jsbterm| |+mouse_urxvt|
8765 |+mouse_sgr|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008766 Only "xterm"(2) is really recognized. NetTerm mouse codes are always
8767 recognized, if enabled at compile time. DEC terminal mouse codes
8768 are recognized if enabled at compile time, and 'ttymouse' is not
Bram Moolenaare968e362014-05-13 20:23:24 +02008769 "xterm", "xterm2", "urxvt" or "sgr" (because dec mouse codes conflict
8770 with them).
Bram Moolenaar071d4272004-06-13 20:20:40 +00008771 This option is automatically set to "xterm", when the 'term' option is
Bram Moolenaar45758762016-10-12 23:08:06 +02008772 set to a name that starts with "xterm", "mlterm", "screen", "tmux",
8773 "st" (full match only), "st-" or "stterm", and 'ttymouse' is not set
8774 already.
Bram Moolenaar06cd14d2023-01-10 12:37:38 +00008775 If the terminfo/termcap entry "XM" exists and the first number is
8776 "1006" then 'ttymouse' will be set to "sgr". This works for many
8777 modern terminals.
Bram Moolenaare968e362014-05-13 20:23:24 +02008778 Additionally, if vim is compiled with the |+termresponse| feature and
8779 |t_RV| is set to the escape sequence to request the xterm version
Bram Moolenaarf8a07122019-07-01 22:06:07 +02008780 number, more intelligent detection is done.
Bram Moolenaar071d4272004-06-13 20:20:40 +00008781 The "xterm2" value will be set if the xterm version is reported to be
Bram Moolenaard47d5222018-12-09 20:43:55 +01008782 from 95 to 276. The "sgr" value will be set if Vim detects Mac
8783 Terminal.app, iTerm2 or mintty, and when the xterm version is 277 or
8784 higher.
Bram Moolenaare968e362014-05-13 20:23:24 +02008785 If you do not want 'ttymouse' to be set to "xterm2" or "sgr"
8786 automatically, set t_RV to an empty string: >
Bram Moolenaar071d4272004-06-13 20:20:40 +00008787 :set t_RV=

8791 global
8792 Maximum number of lines to scroll the screen. If there are more lines
8793 to scroll the window is redrawn. For terminals where scrolling is
8794 very slow and redrawing is not slow this can be set to a small number,
8795 e.g., 3, to speed up displaying.

Bram Moolenaar6a244fe2010-05-24 22:02:24 +02008808 "." means using the directory of the file. The undo file name for
8809 "file.txt" is ".file.txt.un~".
8810 For other directories the file name is the full path of the edited
8811 file, with path separators replaced with "%".
Bram Moolenaar55debbe2010-05-23 23:34:36 +02008812 When writing: The first directory that exists is used. "." always
8813 works, no directories after "." will be used for writing.
8814 When reading all entries are tried to find an undo file. The first
8815 undo file that exists is used. When it cannot be read an error is
8816 given, no further entry is used.
8817 See |undo-persistence|.
Bram Moolenaar110289e2019-05-23 15:38:06 +02008818 This option cannot be set from a |modeline| or in the |sandbox|, for

Bram Moolenaar55debbe2010-05-23 23:34:36 +02008825 When on, Vim automatically saves undo history to an undo file when
8826 writing a buffer to a file, and restores undo history from the same
8827 file on buffer read.
Bram Moolenaarb230bd52010-05-25 21:02:00 +02008828 The directory where the undo file is stored is specified by 'undodir'.

Bram Moolenaar5be4cee2019-09-27 19:34:08 +02008839 is kept in memory, higher numbers will cause more memory to be used.

8876 recovery |crash-recovery|). 'updatecount' is set to zero by starting
8877 Vim with the "-n" option, see |startup|. When editing in readonly

9147 NONE Alternative spelling of "none".
Bram Moolenaar97b2ad32006-03-18 21:40:56 +00009148
Bram Moolenaar071d4272004-06-13 20:20:40 +00009149 Virtual editing means that the cursor can be positioned where there is
Bram Moolenaarebcbd022007-05-12 14:28:25 +00009150 no actual character. This can be halfway into a tab or beyond the end
Bram Moolenaar071d4272004-06-13 20:20:40 +00009151 of the line. Useful for selecting a rectangle in Visual mode and
9152 editing a table.
Bram Moolenaarefd2bf12006-03-16 21:41:35 +00009153 "onemore" is not the same, it will only allow moving the cursor just
9154 after the last character of the line. This makes some commands more
9155 consistent. Previously the cursor was always past the end of the line
9156 if the line was empty. But it is far from Vi compatible. It may also
Bram Moolenaar97b2ad32006-03-18 21:40:56 +00009157 break some plugins or Vim scripts. For example because |l| can move
9158 the cursor after the last character. Use with care!
Bram Moolenaar9ba7e172013-07-17 22:37:26 +02009159 Using the `$` command will move to the last character in the line, not
Bram Moolenaar97b2ad32006-03-18 21:40:56 +00009160 past it. This may actually move the cursor to the left!
Bram Moolenaar9ba7e172013-07-17 22:37:26 +02009161 The `g$` command will move to the end of the screen line.
Bram Moolenaarefd2bf12006-03-16 21:41:35 +00009162 It doesn't make sense to combine "all" with "onemore", but you will
9163 not get a warning for it.
Bram Moolenaar53f7fcc2021-07-28 20:10:16 +02009164 When combined with other words, "none" is ignored.

Bram Moolenaar74675a62017-07-15 13:53:23 +02009172 use: >
9173 :set vb t_vb=
9174< If you want a short flash, you can use this on many terminals: >
9175 :set vb t_vb=[?5h$<100>[?5l
9176< Here $<100> specifies the time, you can use a smaller or bigger value
9177 to get a shorter or longer flash.
9178
9179 Note: Vim will limit the bell to once per half a second. This avoids
9180 having to wait for the flashing to finish when there are lots of
9181 bells, e.g. on key repeat. This also happens without 'visualbell'
9182 set.
9183
Bram Moolenaar071d4272004-06-13 20:20:40 +00009184 In the GUI, 't_vb' defaults to "<Esc>|f", which inverts the display
9185 for 20 msec. If you want to use a different time, use "<Esc>|40f",
9186 where 40 is the time in msec.
Bram Moolenaar74675a62017-07-15 13:53:23 +02009187
9188 Note: When the GUI starts, 't_vb' is reset to its default value. You
9189 might want to set it again in your |gvimrc|.
9190
Bram Moolenaar071d4272004-06-13 20:20:40 +00009191 Does not work on the Amiga, you always get a screen flash.

9202 global
Bram Moolenaar1d2ba7f2006-02-14 22:29:30 +00009203 This option has the same effect as the 't_xs' terminal option.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009204 It is provided for backwards compatibility with version 4.x.
9205 Setting 'weirdinvert' has the effect of making 't_xs' non-empty, and
9206 vice versa. Has no effect when the GUI is running.

9210 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00009211 Allow specified keys that move the cursor left/right to move to the
9212 previous/next line when the cursor is on the first/last character in
9213 the line. Concatenate characters to allow this for these keys:
9214 char key mode ~
9215 b <BS> Normal and Visual
9216 s <Space> Normal and Visual
Bram Moolenaar87b5ca52006-03-04 21:55:31 +00009217 h "h" Normal and Visual (not recommended)
9218 l "l" Normal and Visual (not recommended)
Bram Moolenaar071d4272004-06-13 20:20:40 +00009219 < <Left> Normal and Visual
9220 > <Right> Normal and Visual
9221 ~ "~" Normal
9222 [ <Left> Insert and Replace
9223 ] <Right> Insert and Replace
9224 For example: >
9225 :set ww=<,>,[,]
9226< allows wrap only when cursor keys are used.
9227 When the movement keys are used in combination with a delete or change
9228 operator, the <EOL> also counts for a character. This makes "3h"
9229 different from "3dh" when the cursor crosses the end of a line. This
9230 is also true for "x" and "X", because they do the same as "dl" and
9231 "dh". If you use this, you may also want to use the mapping
9232 ":map <BS> X" to make backspace delete the character in front of the
9233 cursor.
Bram Moolenaar362e1a32006-03-06 23:29:24 +00009234 When 'l' is included and it is used after an operator at the end of a
Bram Moolenaar589edb32019-09-20 14:38:13 +02009235 line (not an empty line) then it will not move to the next line. This
9236 makes "dl", "cl", "yl" etc. work normally.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009237 NOTE: This option is set to the Vi default value when 'compatible' is
9238 set and to the Vim default value when 'compatible' is reset.

Bram Moolenaar071d4272004-06-13 20:20:40 +00009243 Character you have to type to start wildcard expansion in the
9244 command-line, as specified with 'wildmode'.
Bram Moolenaar446cb832008-06-24 21:56:24 +00009245 More info here: |cmdline-completion|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009246 The character is not recognized when used inside a macro. See
9247 'wildcharm' for that.
Bram Moolenaar34cc7d82021-09-21 20:09:51 +02009248 Some keys will not work, such as CTRL-C, <CR> and Enter.
Yee Cheng Chin8f4fb002023-10-17 10:06:56 +02009249 <Esc> can be used, but hitting it twice in a row will still exit
9250 command-line as a failsafe measure.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009251 Although 'wc' is a number option, you can set it to a special key: >
Bram Moolenaar34cc7d82021-09-21 20:09:51 +02009252 :set wc=<Tab>
Bram Moolenaar071d4272004-06-13 20:20:40 +00009253< NOTE: This option is set to the Vi default value when 'compatible' is
9254 set and to the Vim default value when 'compatible' is reset.

9258 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00009259 'wildcharm' works exactly like 'wildchar', except that it is
Bram Moolenaar582fd852005-03-28 20:58:01 +00009260 recognized when used inside a macro. You can find "spare" command-line
9261 keys suitable for this option by looking at |ex-edit-index|. Normally
Bram Moolenaar071d4272004-06-13 20:20:40 +00009262 you'll never actually type 'wildcharm', just use it in mappings that
9263 automatically invoke completion mode, e.g.: >
9264 :set wcm=<C-Z>
Bram Moolenaar446cb832008-06-24 21:56:24 +00009265 :cnoremap ss so $vim/sessions/*.vim<C-Z>
Bram Moolenaar071d4272004-06-13 20:20:40 +00009266< Then after typing :ss you can use CTRL-P & CTRL-N.

Bram Moolenaar071d4272004-06-13 20:20:40 +00009271 A list of file patterns. A file that matches with one of these
Bram Moolenaar30b65812012-07-12 22:01:11 +02009272 patterns is ignored when expanding |wildcards|, completing file or
9273 directory names, and influences the result of |expand()|, |glob()| and
9274 |globpath()| unless a flag is passed to disable this.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009275 The pattern is used like with |:autocmd|, see |autocmd-patterns|.
9276 Also see 'suffixes'.
9277 Example: >
9278 :set wildignore=*.o,*.obj
9279< The use of |:set+=| and |:set-=| is preferred when adding or removing
9280 a pattern from the list. This avoids problems when a future version

Bram Moolenaar071d4272004-06-13 20:20:40 +00009294 When 'wildmenu' is on, command-line completion operates in an enhanced
9295 mode. On pressing 'wildchar' (usually <Tab>) to invoke completion,
Bram Moolenaar54162322022-08-26 16:58:51 +01009296 the possible matches are shown.
9297 When 'wildoptions' contains "pum", then the completion matches are
9298 shown in a popup menu. Otherwise they are displayed just above the
9299 command line, with the first match highlighted (overwriting the status
9300 line, if there is one).
Yegappan Lakshmanan3908ef52022-02-08 12:08:07 +00009301 Keys that show the previous/next match, such as <Tab> or
Bram Moolenaar071d4272004-06-13 20:20:40 +00009302 CTRL-P/CTRL-N, cause the highlight to move to the appropriate match.
9303 When 'wildmode' is used, "wildmenu" mode is used where "full" is
9304 specified. "longest" and "list" do not start "wildmenu" mode.
Bram Moolenaar26402cb2013-02-20 21:26:00 +01009305 You can check the current mode with |wildmenumode()|.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009306 If there are more matches than can fit in the line, a ">" is shown on
9307 the right and/or a "<" is shown on the left. The status line scrolls
9308 as needed.
9309 The "wildmenu" mode is abandoned when a key is hit that is not used
9310 for selecting a completion.
Yee Cheng Chin2bbd0d32023-10-14 02:23:45 -07009311 While the "wildmenu" is active, the following keys have special
9312 meanings:
9313 CTRL-P - go to the previous entry
9314 CTRL-N - go to the next entry
Bram Moolenaar071d4272004-06-13 20:20:40 +00009315 <CR> - in menu completion, when the cursor is just after a
9316 dot: move into a submenu.
Yee Cheng Chin209ec902023-10-17 10:56:25 +02009317 CTRL-E - end completion, go back to what was there before
9318 selecting a match.
9319 CTRL-Y - accept the currently selected match and stop
9320 completion.
Yee Cheng Chin2bbd0d32023-10-14 02:23:45 -07009321

Bram Moolenaar071d4272004-06-13 20:20:40 +00009361 "" Complete only the first match.
9362 "full" Complete the next full match. After the last match,
9363 the original string is used and then the first match
Bram Moolenaar130cbfc2021-04-07 21:07:20 +02009364 again. Will also start 'wildmenu' if it is enabled.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009365 "longest" Complete till longest common string. If this doesn't
9366 result in a longer string, use the next part.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009367 "list" When more than one match, list all matches.
Bram Moolenaar130cbfc2021-04-07 21:07:20 +02009368 "lastused" When completing buffer names and more than one buffer
9369 matches, sort buffers by time last used (other than
9370 the current buffer).
9371 When there is only a single match, it is fully completed in all cases.
9372
9373 Examples of useful colon-separated values:
9374 "longest:full" Like "longest", but also start 'wildmenu' if it is
9375 enabled. Will not complete to the next full match.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009376 "list:full" When more than one match, list all matches and

9404 be used for completion. The matches will be sorted by
9405 the "best match" rather than alphabetically sorted.
9406 This will find more matches than the wildcard
9407 expansion. Currently fuzzy matching based completion
9408 is not supported for file and directory names and

Bram Moolenaar071d4272004-06-13 20:20:40 +00009476 Minimal number of lines for the current window. This is not a hard
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00009477 minimum, Vim will use fewer lines if there is not enough room. If the
Bram Moolenaar446cb832008-06-24 21:56:24 +00009478 focus goes to a window that is smaller, its size is increased, at the
9479 cost of the height of other windows.
9480 Set 'winheight' to a small number for normal editing.
9481 Set it to 999 to make the current window fill most of the screen.
9482 Other windows will be only 'winminheight' high. This has the drawback
9483 that ":all" will create only two windows. To avoid "vim -o 1 2 3 4"
9484 to create only two windows, set the option after startup is done,
9485 using the |VimEnter| event: >
9486 au VimEnter * set winheight=999
9487< Minimum value is 1.
9488 The height is not adjusted after one of the commands that change the
Bram Moolenaar071d4272004-06-13 20:20:40 +00009489 height of the current window.
9490 'winheight' applies to the current window. Use 'winminheight' to set
9491 the minimal height for other windows.

Bram Moolenaar071d4272004-06-13 20:20:40 +00009496 The minimal height of a window, when it's not the current window.
9497 This is a hard minimum, windows will never become smaller.
9498 When set to zero, windows may be "squashed" to zero lines (i.e. just a
9499 status bar) if necessary. They will return to at least one line when
9500 they become active (since the cursor has to have somewhere to go.)
9501 Use 'winheight' to set the minimal height of the current window.
9502 This option is only checked when making a window smaller. Don't use a
9503 large number, it will cause errors when opening more than a few
9504 windows. A value of 0 to 3 is reasonable.
9505

9511 When set to zero, windows may be "squashed" to zero columns (i.e. just
9512 a vertical separator) if necessary. They will return to at least one
9513 line when they become active (since the cursor has to have somewhere
9514 to go.)
9515 Use 'winwidth' to set the minimal width of the current window.
9516 This option is only checked when making a window smaller. Don't use a

9525 Specifies the name of the winpty shared library, used for the
Bram Moolenaare7b1ea02020-08-07 19:54:59 +02009526 |:terminal| command. The default depends on whether Vim was built as a
Bram Moolenaarc572da52017-08-27 16:52:01 +02009527 32-bit or 64-bit executable. If not found, "winpty.dll" is tried as

9535 global
Bram Moolenaar071d4272004-06-13 20:20:40 +00009536 Minimal number of columns for the current window. This is not a hard
9537 minimum, Vim will use fewer columns if there is not enough room. If
9538 the current window is smaller, its size is increased, at the cost of
9539 the width of other windows. Set it to 999 to make the current window
9540 always fill the screen. Set it to a small number for normal editing.
9541 The width is not adjusted after one of the commands to change the
9542 width of the current window.
9543 'winwidth' applies to the current window. Use 'winminwidth' to set
9544 the minimal width for other windows.

Bram Moolenaar071d4272004-06-13 20:20:40 +00009549 This option changes how text is displayed. It doesn't change the text
9550 in the buffer, see 'textwidth' for that.
9551 When on, lines longer than the width of the window will wrap and
Bram Moolenaarf4b8e572004-06-24 15:53:16 +00009552 displaying continues on the next line. When off lines will not wrap
9553 and only part of long lines will be displayed. When the cursor is
Bram Moolenaar071d4272004-06-13 20:20:40 +00009554 moved to a part that is not shown, the screen will scroll
9555 horizontally.
9556 The line will be broken in the middle of a word if necessary. See
9557 'linebreak' to get the break at a word boundary.
9558 To make scrolling horizontally a bit more useful, try this: >
9559 :set sidescroll=5
9560 :set listchars+=precedes:<,extends:>
9561< See 'sidescroll', 'listchars' and |wrap-off|.
Bram Moolenaar8f3f58f2010-01-06 20:52:26 +01009562 This option can't be set from a |modeline| when the 'diff' option is

9567 local to buffer
9568 Number of characters from the right window border where wrapping
9569 starts. When typing text beyond this limit, an <EOL> will be inserted
9570 and inserting continues on the next line.
9571 Options that add a margin, such as 'number' and 'foldcolumn', cause
9572 the text width to be further reduced. This is Vi compatible.
9573 When 'textwidth' is non-zero, this option is not used.
Bram Moolenaarca635012015-09-25 20:34:21 +02009574 This option is set to 0 when 'paste' is set and restored when 'paste'

Bram Moolenaar1aeaf8c2012-05-18 13:46:39 +02009604 also on.
9605 WARNING: Switching this option off means that when Vim fails to write
9606 your buffer correctly and then, for whatever reason, Vim exits, you
9607 lose both the original file and what you were writing. Only reset
9608 this option if your file system is almost full and it makes the write
9609 fail (and make sure not to exit Vim until the write was successful).
9610 See |backup-table| for another explanation.
Bram Moolenaar071d4272004-06-13 20:20:40 +00009611 When the 'backupskip' pattern matches, a backup is not made anyway.
Bram Moolenaar0c0734d2019-11-26 21:44:46 +01009612 Depending on 'backupcopy' the backup is a new file or the original
9613 file renamed (and a new file is written).
Bram Moolenaar071d4272004-06-13 20:20:40 +00009614 NOTE: This option is set to the default value when 'compatible' is

Bram Moolenaarfa3b7232021-12-24 13:18:38 +00009628 mechanism and this option is set, Vim will request the actual terminal
Bram Moolenaar6f79e612021-12-21 09:12:23 +00009629 key codes and number of colors from the terminal. This takes care of
9630 various configuration options of the terminal that cannot be obtained
9631 from the termlib/terminfo entry, see |xterm-codes|.
9632 A side effect may be that t_Co changes and Vim will redraw the
