IdeaVim REFERENCE MANUAL by Rick Maddy
Options *options*
1. Setting options |set-option|
2. Automatically setting options |auto-setting|
3. Options summary |option-summary|
For an overview of options see help.txt |option-list|.
Vim has a number of internal variables and switches which can be set to
achieve special effects. These options come in three forms:
boolean can only be on or off *boolean* *toggle*
number has a numeric value
string has a string value
==============================================================================
1. Setting options *set-option*
*:se* *:set*
:se[t] Show all options that differ from their default value.
:se[t] all Show all but terminal options.
<!--
:se[t] termcap Show all terminal options. Note that in the GUI the
key codes are not shown, because they are generated
internally and can't be changed. Changing the terminal
codes in the GUI is not useful either...
*E518* *E519*
-->
:se[t] {option}? Show value of {option}.
:se[t] {option} Toggle option: set, switch it on.
Number option: show value.
String option: show value.
:se[t] no{option} Toggle option: Reset, switch it off.
:se[t] {option}! or
:se[t] inv{option} Toggle option: Invert value.
*:set-default* *:set-&* *:set-&vi* *:set-&vim*
:se[t] {option}& Reset option to its default value. May depend on the
current value of 'compatible'.
<!--
:se[t] {option}&vi Reset option to its Vi default value.
:se[t] {option}&vim Reset option to its Vim default value.
-->
:se[t] all& Set all options, except terminal options, to their
default value. The values of 'term', 'lines' and
'columns' are not changed.
*E487* *E521*
:se[t] {option}={value} or
:se[t] {option}:{value}
Set string or number option to {value}.
*:set-args*
For numeric options the value can be given in decimal,
hex (preceded with 0x) or octal (preceded with '0')
(hex and octal are only available for machines which
have the strtol() function).
<!--
The old value can be inserted by typing 'wildchar' (by
default this is a <Tab> or CTRL-E if 'compatible' is
set). See |cmdline-completion|.
-->
White space between {option} and '=' is allowed and
will be ignored. White space between '=' and {value}
is not allowed.
See |option-backslash| for using white space and
backslashes in {value}.
:se[t] {option}+={value} *:set+=*
Add the {value} to a number option, or append the
{value} to a string option. When the option is a
comma separated list, a comma is added, unless the
value was empty.
If the option is a list of flags, superfluous flags
are removed. Otherwise there is no check for doubled
values. You can avoid this by removing a value first.
Example: >
:set guioptions-=T guioptions+=T
< Also see |:set-args| above.
:se[t] {option}^={value} *:set^=*
Multiply the {value} to a number option, or prepend
the {value} to a string option. When the option is a
comma separated list, a comma is added, unless the
value was empty.
Also see |:set-args| above.
:se[t] {option}-={value} *:set-=*
Subtract the {value} from a number option, or remove
the {value} from a string option, if it is there.
If the {value} is not found in a string option, there
is no error or warning. When the option is a comma
separated list, a comma is deleted, unless the option
becomes empty.
When the option is a list of flags, {value} must be
exactly as they appear in the option. Remove flags
one by one to avoid problems.
Also see |:set-args| above.
The {option} arguments to ":set" may be repeated. For example: >
:set ai nosi sw=3 ts=3
If you make an error in one of the arguments, an error message will be given
and the following arguments will be ignored.
<!--
*:set-verbose*
When 'verbose' is non-zero, displaying an option value will also tell where it
was last set. Example: >
:verbose set shiftwidth cindent?
shiftwidth=4
Last set from modeline
cindent
Last set from /usr/local/share/vim/vim60/ftplugin/c.vim
This is only done when specific option values are requested, not for ":set
all" or ":set" without an argument.
When the option was set by hand there is no "Last set" message. There is only
one value for all local options with the same name. Thus the message applies
to the option name, not necessarily its value.
When the option was set while executing a function, user command or
autocommand, the script in which it was defined is reported.
Note that an option may also have been set as a side effect of setting
'compatible'.
{not available when compiled without the +eval feature}
*:set-termcap* *E522*
For {option} the form "t_xx" may be used to set a termcap option. This will
override the value from the termcap. You can then use it in a mapping. If
the "xx" part contains special characters, use the <t_xx> form: >
:set <t_#4>=^[Ot
This can also be used to translate a special code for a normal key. For
example, if Alt-b produces <Esc>b, use this: >
:set <M-b>=^[b
(the ^[ is a real <Esc> here, use CTRL-V <Esc> to enter it)
The advantage over a mapping is that it works in all situations.
The listing from ":set" looks different from Vi. Long string options are put
at the end of the list. The number of options is quite large. The output of
"set all" probably does not fit on the screen, causing Vim to give the
|more-prompt|.
-->
*option-backslash*
To include white space in a string option value it has to be preceded with a
backslash. To include a backslash you have to use two. Effectively this
means that the number of backslashes in an option value is halved (rounded
down).
A few examples: >
:set tags=tags\ /usr/tags results in "tags /usr/tags"
:set tags=tags\\,file results in "tags\,file"
:set tags=tags\\\ file results in "tags\ file"
<!--
The "|" character separates a ":set" command from a following command. To
include the "|" in the option value, use "\|" instead. This example sets the
'titlestring' option to "hi|there": >
:set titlestring=hi\|there
This sets the 'titlestring' option to "hi" and 'iconstring' to "there": >
:set titlestring=hi|set iconstring=there
For MS-DOS and WIN32 backslashes in file names are mostly not removed. More
precise: For options that expect a file name (those where environment
variables are expanded) a backslash before a normal file name character is not
removed. But a backslash before a special character (space, backslash, comma,
etc.) is used like explained above.
There is one special situation, when the value starts with "\\": >
:set dir=\\machine\path results in "\\machine\path"
:set dir=\\\\machine\\path results in "\\machine\path"
:set dir=\\path\\file results in "\\path\file" (wrong!)
For the first one the start is kept, but for the second one the backslashes
are halved. This makes sure it works both when you expect backslashes to be
halved and when you expect the backslashes to be kept. The third gives a
result which is probably not what you want. Avoid it.
*add-option-flags* *remove-option-flags*
*E539* *E550* *E551* *E552*
Some options are a list of flags. When you want to add a flag to such an
option, without changing the existing ones, you can do it like this: >
:set guioptions+=a
Remove a flag from an option like this: >
:set guioptions-=a
This removes the 'a' flag from 'guioptions'.
Note that you should add or remove one flag at a time. If 'guioptions' has
the value "ab", using "set guioptions-=ba" won't work, because the string "ba"
doesn't appear.
*:set_env* *expand-env* *expand-environment-var*
Environment variables in most string options will be expanded. If the
environment variable exists the '$' and the following environment variable
name is replaced with its value. If it does not exist the '$' and the name
are not modified. Any non-id character (not a letter, digit or '_') may
follow the environment variable name. That character and what follows is
appended to the value of the environment variable. Examples: >
:set term=$TERM.new
:set path=/usr/$INCLUDE,$HOME/include,.
When adding or removing a string from an option with ":set opt-=val" or ":set
opt+=val" the expansion is done before the adding or removing.
Handling of local options *local-options*
Some of the options only apply to a window or buffer. Each window or buffer
has its own copy of this option, thus can each have their own value. This
allows you to set 'list' in one window but not in another. And set
'shiftwidth' to 3 in one buffer and 4 in another.
The following explains what happens to these local options in specific
situations. You don't really need to know all of this, since Vim mostly uses
the option values you would expect. Unfortunately, doing what the user
expects is a bit complicated...
When splitting a window, the local options are copied to the new window. Thus
right after the split the contents of the two windows look the same.
When editing a new buffer, its local option values must be initialized. Since
the local options of the current buffer might be specifically for that buffer,
these are not used. Instead, for each buffer-local option there also is a
global value, which is used for new buffers. With ":set" both the local and
global value is changed. With "setlocal" only the local value is changed,
thus this value is not used when editing a new buffer.
When editing a buffer that has been edited before, the last used window
options are used again. If this buffer has been edited in this window, the
values from back then are used. Otherwise the values from the window where
the buffer was edited last are used.
It's possible to set a local window option specifically for a type of buffer.
When you edit another buffer in the same window, you don't want to keep
using these local window options. Therefore Vim keeps a global value of the
local window options, which is used when editing another buffer. Each window
has its own copy of these values. Thus these are local to the window, but
global to all buffers in the window. With this you can do: >
:e one
:set list
:e two
Now the 'list' option will also be set in "two", since with the ":set list"
command you have also set the global value. >
:set nolist
:e one
:setlocal list
:e two
Now the 'list' option is not set, because ":set nolist" resets the global
value, ":setlocal list" only changes the local value and ":e two" gets the
global value. Note that if you do this next: >
:e one
You will not get back the 'list' value as it was the last time you edited
"one". The options local to a window are not remembered for each buffer.
*:setl* *:setlocal*
:setl[ocal] ... Like ":set" but set only the value local to the
current buffer or window. Not all options have a
local value. If the option does not have a local
value the global value is set.
With the "all" argument: display all local option's
local values.
Without argument: Display all local option's local
values which are different from the default.
When displaying a specific local option, show the
local value. For a global option the global value is
shown (but that might change in the future).
:setl[ocal] {option}< Set the local value of {option} to its global value.
*:setg* *:setglobal*
:setg[lobal] ... Like ":set" but set only the global value for a local
option without changing the local value.
When displaying an option, the global value is shown.
With the "all" argument: display all local option's
global values.
Without argument: display all local option's global
values which are different from the default.
For buffer-local and window-local options:
Command global value local value ~
:set option=value set set
:setlocal option=value - set
:setglobal option=value set -
:set option? - display
:setlocal option? - display
:setglobal option? display -
Global options with a local value *global-local*
Options are global when you mostly use one value for all buffers. For some
global options it's useful to sometimes have a different local value. You can
set the local value with ":setlocal". That buffer will then use the local
value, while other buffers continue using the global value.
For example, you have two windows, both on C source code. They use the global
'makeprg' option. If you do this in one of the two windows: >
:set makeprg=gmake
then the other window will switch to the same value. There is no need to set
the 'makeprg' option in the other C source window too.
However, if you start editing a Perl file in a new window, you want to use
another 'makeprog' for it, without changing the value used for the C source
files. You use this command: >
:setlocal makeprg=perlmake
You can switch back to using the global value by making the local value empty: >
:setlocal makeprg=
This only works for a string option. For a boolean option you need to use the
"<" flag, like this: >
:setlocal autoread<
Note that for non-boolean options using "<" copies the global value to the
local value, it doesn't switch back to using the global value (that matters
when changing the global value later).
Note: In the future more global options can be made global-local. Using
":setlocal" on a global option might work differently then.
Setting the filetype
:setf[iletype] {filetype} *:setf* *:setfiletype*
Set the 'filetype' option to {filetype}, but only if
not done yet in a sequence of (nested) autocommands.
This is short for: >
:if !did_filetype()
: setlocal filetype={filetype}
:endif
< This command is used in a filetype.vim file to avoid
setting the 'filetype' option twice, causing different
settings and syntax files to be loaded.
:bro[wse] se[t] *:set-browse* *:browse-set* *:opt* *:options*
:opt[ions] Open a window for viewing and setting all options.
Options are grouped by function.
Offers short help for each option. Hit <CR> on the
short help to open a help window with more help for
the option.
Modify the value of the option and hit <CR> on the
"set" line to set the new value. For window and
buffer specific options, the last accessed window is
used to set the option value in, unless this is a help
window, in which case the window below help window is
used (skipping the option-window).
{not available when compiled without the |+eval| or
|+autocmd| features}
*$HOME*
Using "~" is like using "$HOME", but it is only recognized at the start of an
option and after a space or comma.
On Unix systems "~user" can be used too. It is replaced by the home directory
of user "user". Example: >
:set path=~mool/include,/usr/include,.
On Unix systems the form "${HOME}" can be used too. The name between {} can
contain non-id characters then. Note that if you want to use this for the
"gf" command, you need to add the '{' and '}' characters to 'isfname'.
Note the maximum length of an expanded option is limited. How much depends on
the system, mostly it is something like 256 or 1024 characters.
*:fix* *:fixdel*
:fix[del] Set the value of 't_kD':
't_kb' is 't_kD' becomes ~
CTRL-? CTRL-H
not CTRL-? CTRL-?
(CTRL-? is 0177 octal, 0x7f hex)
If your delete key terminal code is wrong, but the
code for backspace is alright, you can put this in
your .vimrc: >
:fixdel
< This works no matter what the actual code for
backspace is.
If the backspace key terminal code is wrong you can
use this: >
:if &term == "termname"
: set t_kb=^V<BS>
: fixdel
:endif
< Where "^V" is CTRL-V and "<BS>" is the backspace key
(don't type four characters!). Replace "termname"
with your terminal name.
If your <Delete> key sends a strange key sequence (not
CTRL-? or CTRL-H) you cannot use ":fixdel". Then use: >
:if &term == "termname"
: set t_kD=^V<Delete>
:endif
< Where "^V" is CTRL-V and "<Delete>" is the delete key
(don't type eight characters!). Replace "termname"
with your terminal name.
*Linux-backspace*
Note about Linux: By default the backspace key
produces CTRL-?, which is wrong. You can fix it by
putting this line in your rc.local: >
echo "keycode 14 = BackSpace" | loadkeys
<
*NetBSD-backspace*
Note about NetBSD: If your backspace doesn't produce
the right code, try this: >
xmodmap -e "keycode 22 = BackSpace"
< If this works, add this in your .Xmodmap file: >
keysym 22 = BackSpace
< You need to restart for this to take effect.

==============================================================================
2. Automatically setting options *auto-setting*
Besides changing options with the ":set" command, there are three alternatives
to set options automatically for one or more files:
1. When starting Vim initializations are read from various places. See
|initialization|. Most of them are performed for all editing sessions,
and some of them depend on the directory where Vim is started.
<!--
You can create an initialization file with |:mkvimrc|, |:mkview| and
|:mksession|.
2. If you start editing a new file, the automatic commands are executed.
This can be used to set options for files matching a particular pattern and
many other things. See |autocommand|.
3. If you start editing a new file, and the 'modeline' option is on, a
number of lines at the beginning and end of the file are checked for
modelines. This is explained here.
*modeline* *vim:* *vi:* *ex:* *E520*
There are two forms of modelines. The first form:
[text]{white}{vi:|vim:|ex:}[white]{options}
[text] any text or empty
{white} at least one white space (<Space> or <Tab>)
{vi:|vim:|ex:} the string "vi:", "vim:" or "ex:"
[white] optional white space
{options} a list of option settings, separated with white space or ':',
where each part between ':' is the argument for a ":set"
command
Example: >
vi:noai:sw=3 ts=6
The second form (this is compatible with some versions of Vi):
[text]{white}{vi:|vim:|ex:}[white]se[t] {options}:[text]
[text] any text or empty
{white} at least one white space (<Space> or <Tab>)
{vi:|vim:|ex:} the string "vi:", "vim:" or "ex:"
[white] optional white space
se[t] the string "set " or "se " (note the space)
{options} a list of options, separated with white space, which is the
argument for a ":set" command
: a colon
[text] any text or empty
Example: >
/* vim: set ai tw=75: */
The white space before {vi:|vim:|ex:} is required. This minimizes the chance
that a normal word like "lex:" is caught. There is one exception: "vi:" and
"vim:" can also be at the start of the line (for compatibility with version
3.0). Using "ex:" at the start of the line will be ignored (this could be
short for "example:").
*modeline-local*
The options are set like with ":setlocal": The new value only applies to the
buffer that contains the window. Although it's possible to set global options
from a modeline, this is unusual. If you have two windows open and the files
in it set the same global option to a different value, the result depends on
which one was opened last.
*modeline-version*
If the modeline is only to be used for some versions of Vim, the version
number can be specified where "vim:" is used:
vim{vers}: version {vers} or later
vim<{vers}: version before {vers}
vim={vers}: version {vers}
vim>{vers}: version after {vers}
{vers} is 600 for Vim 6.0 (hundred times the major version plus minor).
For example, to use a modeline only for Vim 6.0 and later: >
/* vim600: set foldmethod=marker: */
To use a modeline for Vim before version 5.7: >
/* vim<570: set sw=4: */
There can be no blanks between "vim" and the ":".
The number of lines that are checked can be set with the 'modelines' option.
If 'modeline' is off or 'modelines' is 0 no lines are checked.
Note that for the first form all of the rest of the line is used, thus a line
like: >
/* vi:ts=4: */
will give an error message for the trailing "*/". This line is OK: >
/* vi:set ts=4: */
If an error is detected the rest of the line is skipped.
If you want to include a ':' in a set command precede it with a '\'. The
backslash in front of the ':' will be removed. Example: >
/* vi:set dir=c\:\tmp: */
This sets the 'dir' option to "c:\tmp". Only a single backslash before the
':' is removed. Thus to include "\:" you have to specify "\\:".
No other commands than "set" are supported, for security reasons (somebody
might create a Trojan horse text file with modelines).
Hint: If you would like to do something else than setting an option, you could
define an autocommand that checks the file for a specific string. For
example: >
au BufReadPost * if getline(1) =~ "VAR" | call SetVar() | endif
And define a function SetVar() that does something with the line containing
"VAR".
-->
==============================================================================
3. Options summary *option-summary*
In the list below all the options are mentioned with their full name and with
an abbreviation if there is one. Both forms may be used.
In this document when a boolean option is "set" that means that ":set option"
is entered. When an option is "reset", ":set nooption" is used.
<!--
For some options there are two default values: The "Vim default", which is
used when 'compatible' is not set, and the "Vi default", which is used when
'compatible' is set.
Most options are the same in all windows and buffers. There are a few that
are specific to how the text is presented in a window. These can be set to a
different value in each window. For example the 'list' option can be set in
one window and reset in another for the same text, giving both types of view
at the same time. There are a few options that are specific to a certain
file. These can have a different value for each file or buffer. For example
the 'textwidth' option can be 78 for a normal text file and 0 for a C
program.
global one option for all buffers and windows
local to window each window has its own copy of this option
local to buffer each buffer has its own copy of this option
When creating a new window the option values from the currently active window
are used as a default value for the window-specific options. For the
buffer-specific options this depends on the 's' and 'S' flags in the
'cpoptions' option. If 's' is included (which is the default) the values for
buffer options are copied from the currently active buffer when a buffer is
first entered. If 'S' is present the options are copied each time the buffer
is entered, this is almost like having global options. If 's' and 'S' are not
present, the options are copied from the currently active buffer when the
buffer is created.
Not all options are supported in all versions. To test if option "foo" can be
used with ":set" use "exists('&foo')". This doesn't mean the value is
actually remembered and works. Some options are hidden, which means that you
can set them but the value is not remembered. To test if option "foo" is
really supported use "exists('+foo')".
-->
*E355*
A jump table for the options with a short description can be found at |Q_op|.
<!--
*'aleph'* *'al'* *aleph* *Aleph*
'aleph' 'al' number (default 128 for MS-DOS, 224 otherwise)
global
The ASCII code for the first letter of the Hebrew alphabet. The
routine that maps the keyboard in Hebrew mode, both in Insert mode
(when hkmap is set) and on the command-line (when hitting CTRL-_)
outputs the Hebrew characters in the range [aleph..aleph+26].
aleph=128 applies to PC code, and aleph=224 applies to ISO 8859-8.
See |rileft.txt|.
*'allowrevins'* *'ari'* *'noallowrevins'* *'noari'*
'allowrevins' 'ari' boolean (default off)
global
Allow CTRL-_ in Insert and Command-line mode. This is default off, to
avoid that users that accidentally type CTRL-_ instead of SHIFT-_ get
into reverse Insert mode, and don't know how to get out. See
'revins'.
NOTE: This option is reset when 'compatible' is set.
*'altkeymap'* *'akm'* *'noaltkeymap'* *'noakm'*
'altkeymap' 'akm' boolean (default off)
global
When on, the second language is Farsi. In editing mode CTRL-_ toggles
the keyboard map between Farsi and English, when 'allowrevins' set.
When off, the keyboard map toggles between Hebrew and English. This
is useful to start the vim in native mode i.e. English (left-to-right
mode) and have default second language Farsi or Hebrew (right-to-left
mode). See |farsi.txt|.
*'ambiwidth'* *'ambw'*
'ambiwidth' 'ambw' string (default: "single")
global
Only effective when 'encoding' is "utf-8" or another Unicode encoding.
Tells Vim what to do with characters with East Asian Width Class
Ambiguous (such as Euro, Registered Sign, Copyright Sign, Greek
letters, Cyrillic letters).
There are currently two possible values:
"single": Use the same width as characters in US-ASCII. This is
expected by most users.
"double": Use twice the width of ASCII characters.
There are a number of CJK fonts for which the width of glyphs for
those characters are solely based on how many octets they take in
legacy/traditional CJK encodings. In those encodings, Euro,
Registered sign, Greek/Cyrillic letters are represented by two octets,
therefore those fonts have "wide" glyphs for them. This is also
true of some line drawing characters used to make tables in text
file. Therefore, when a CJK font is used for GUI vim or
vim is running inside a terminal (emulators) that uses a CJK font
(or vim is run inside an xterm invoked with "-cjkwidth" option.),
this option should be set to "double" to match the width perceived
by Vim with the width of glyphs in the font. Perhaps it also has
to be set to "double" under CJK Windows 9x/ME or Windows 2k/XP
when the system locale is set to one of CJK locales. See Unicode
Standard Annex #11 (http://www.unicode.org/reports/tr11).
*'autochdir'* *'acd'* *'noatuochdir'* *'noacd'*
'autochdir' 'acd' boolean (default off)
global
When on, vim will change its value for the current working directory
whenever you open a file, switch buffers, delete a buffer or
open/close a window. It will change to the directory containing the
file which was opened or selected. This option is provided for
backward compatibility with the vim released with Sun ONE Studio 4
Enterprise Edition.
*'arabic'* *'arab'* *'noarabic'* *'noarab'*
'arabic' 'arab' boolean (default off)
local to window
This option can be set to start editing Arabic text.
Setting this option will:
- Set the 'rightleft' option, unless 'termbidi' is set.
- Set the 'arabicshape' option, unless 'termbidi' is set.
- Set the 'keymap' option to "arabic"; in Insert mode CTRL-^ toggles
between typing English and Arabic key mapping.
- Set the 'delcombine' option
Note that 'encoding' must be "utf-8" for working with Arabic text.
Resetting this option will:
- Reset the 'rightleft' option.
- Disable the use of 'keymap' (without changing its value).
Note that 'arabicshape' and 'delcombine' are not reset (it is a global
option.
Also see |arabic.txt|.
*'arabicshape'* *'arshape'*
*'noarabicshape'* *'noarshape'*
'arabicshape' 'arshape' boolean (default on)
global
When on and 'termbidi' is off, the required visual character
corrections that need to take place for displaying the Arabic language
take affect. Shaping, in essence, gets enabled; the term is a broad
one which encompasses:
a) the changing/morphing of characters based on their location
within a word (initial, medial, final and stand-alone).
b) the enabling of the ability to compose characters
c) the enabling of the required combining of some characters
When disabled the character display reverts back to each character's
true stand-alone form.
Arabic is a complex language which requires other settings, for
further details see |arabic.txt|.
*'autoindent'* *'ai'* *'noautoindent'* *'noai'*
'autoindent' 'ai' boolean (default off)
local to buffer
Copy indent from current line when starting a new line (typing <CR>
in Insert mode or when using the "o" or "O" command). If you do not
type anything on the new line except <BS> or CTRL-D and then type
<Esc> or <CR>, the indent is deleted again. When autoindent is on,
formatting (with the "gq" command or when you reach 'textwidth' in
Insert mode) uses the indentation of the first line.
When 'smartindent' or 'cindent' is on the indent is changed in
a different way.
The 'autoindent' option is reset when the 'paste' option is set.
{small difference from Vi: After the indent is deleted when typing
<Esc> or <CR>, the cursor position when moving up or down is after the
deleted indent; Vi puts the cursor somewhere in the deleted indent}.
*'autoread'* *'ar'* *'noautoread'* *'noar'*
'autoread' 'ar' boolean (default off)
global or local to buffer |global-local|
When a file has been detected to have been changed outside of Vim and
it has not been changed inside of Vim, automatically read it again.
When the file has been deleted this is not done. |timestamp|
If this option has a local value, use this command to switch back to
using the global value: >
:set autoread<
<
*'autowrite'* *'aw'* *'noautowrite'* *'noaw'*
'autowrite' 'aw' boolean (default off)
global
Write the contents of the file, if it has been modified, on each
:next, :rewind, :last, :first, :previous, :stop, :suspend, :tag, :!,
:make, CTRL-] and CTRL-^ command; and when a CTRL-O, CTRL-I,
'{A-Z0-9}, or `{A-Z0-9} command takes one to another file.
Note that for some commands the 'autowrite' option is not used, see
'autowriteall' for that.
*'autowriteall'* *'awa'* *'noautowriteall'* *'noawa'*
'autowriteall' 'awa' boolean (default off)
global
Like 'autowrite', but also used for commands ":edit", ":quit",
":qall", ":exit", ":xit", ":recover" and closing the Vim window.
Setting this option also implies that Vim behaves like 'autowrite' has
been set.
*'background'* *'bg'*
'background' 'bg' string (default "dark" or "light")
global
When set to "dark", Vim will try to use colors that look good on a
dark background. When set to "light", Vim will try to use colors that
look good on a light background. Any other value is illegal.
Vim tries to set the default value according to the terminal used.
This will not always be correct.
Setting this option does not change the background color, it tells Vim
what the background color looks like. For changing the background
color, see |:hi-normal|.
When 'background' is set Vim will adjust the default color groups for
the new value. But the colors used for syntax highlighting will not
change.
When a color scheme is loaded (the "colors_name" variable is set)
setting 'background' will cause the color scheme to be reloaded. If
the color scheme adjusts to the value of 'background' this will work.
However, if the color scheme sets 'background' itself the effect may
be undone. First delete the "colors_name" variable when needed.
When setting 'background' to the default value with: >
:set background&
< Vim will guess the value. In the GUI this should work correctly,
in other cases Vim might not be able to guess the right value.
When starting the GUI, the default value for 'background' will be
"light". When the value is not set in the .gvimrc, and Vim detects
that the background is actually quite dark, 'background' is set to
"dark". But this happens only AFTER the .gvimrc file has been read
(because the window needs to be opened to find the actual background
color). To get around this, force the GUI window to be opened by
putting a ":gui" command in the .gvimrc file, before where the value
of 'background' is used (e.g., before ":syntax on").
Normally this option would be set in the .vimrc file. Possibly
depending on the terminal name. Example: >
:if &term == "pcterm"
: set background=dark
:endif
< When this option is set, the default settings for the highlight groups
will change. To use other settings, place ":highlight" commands AFTER
the setting of the 'background' option.
This option is also used in the "$VIMRUNTIME/syntax/syntax.vim" file
to select the colors for syntax highlighting. After changing this
option, you must load syntax.vim again to see the result. This can be
done with ":syntax on".
*'backspace'* *'bs'*
'backspace' 'bs' string (default "")
global
Influences the working of <BS>, <Del>, CTRL-W and CTRL-U in Insert
mode. This is a list of items, separated by commas. Each item allows
a way to backspace over something:
value effect ~
indent allow backspacing over autoindent
eol allow backspacing over line breaks (join lines)
start allow backspacing over the start of insert; CTRL-W and CTRL-U
stop once at the start of insert.
When the value is empty, Vi compatible backspacing is used.
For backwards compatibility with version 5.4 and earlier:
value effect ~
0 same as ":set backspace=" (Vi compatible)
1 same as ":set backspace=indent,eol"
2 same as ":set backspace=indent,eol,start"
See |:fixdel| if your <BS> or <Del> key does not do what you want.
NOTE: This option is set to "" when 'compatible' is set.
*'backup'* *'bk'* *'nobackup'* *'nobk'*
'backup' 'bk' boolean (default off)
global
Make a backup before overwriting a file. Leave it around after the
file has been successfully written. If you do not want to keep the
backup file, but you do want a backup while the file is being
written, reset this option and set the 'writebackup' option (this is
the default). If you do not want a backup file at all reset both
options (use this if your file system is almost full). See the
|backup-table| for more explanations.
When the 'backupskip' pattern matches, a backup is not made anyway.
When 'patchmode' is set, the backup may be renamed to become the
oldest version of a file.
NOTE: This option is reset when 'compatible' is set.
*'backupcopy'* *'bkc'*
'backupcopy' 'bkc' string (Vi default for Unix: "yes", otherwise: "auto")
global
When writing a file and a backup is made, this option tells how it's
done:
"yes" make a copy of the file and overwrite the original one
"no" rename the file and write a new one
"auto" one of the previous, what works best
Making a copy and overwriting the original file:
- Takes extra time to copy the file.
+ When the file has special attributes, is a (hard/symbolic) link or
has a resource fork, all this is preserved.
- When the file is a link the backup will have the name of the link,
not of the real file.
Renaming the file and writing a new one:
+ It's fast.
- Sometimes not all attributes of the file can be copied to the new
file.
- When the file is a link the new file will not be a link.
The "auto" value is the middle way: When Vim sees that renaming file
is possible without side effects (the attributes can be passed on and
and the file is not a link) that is used. When problems are expected,
a copy will be made.
*crontab*
One situation where "no" and "auto" will cause problems: A program
that opens a file, invokes Vim to edit that file, and then tests if
the open file was changed (through the file descriptor) will check the
backup file instead of the newly created file. "crontab -e" is an
example.
When a copy is made, the original file is truncated and then filled
with the new text. This means that protection bits, owner and
symbolic links of the original file are unmodified. The backup file
however, is a new file, owned by the user who edited the file. The
group of the backup is set to the group of the original file. If this
fails, the protection bits for the group are made the same as for
others.
When the file is renamed this is the other way around: The backup has
the same attributes of the original file, and the newly written file
is owned by the current user. When the file was a (hard/symbolic)
link, the new file will not! That's why the "auto" value doesn't
rename when the file is a link. The owner and group of the newly
written file will be set to the same ones as the original file, but
the system may refuse to do this. In that case the "auto" value will
again not rename the file.
*'backupdir'* *'bdir'*
'backupdir' 'bdir' string (default for Amiga: ".,t:",
for MS-DOS and Win32: ".,c:/tmp,c:/temp"
for Unix: ".,~/tmp,~/")
global
List of directories for the backup file, separated with commas.
- The backup file will be created in the first directory in the list
where this is possible.
- Empty means that no backup file will be created ('patchmode' is
impossible!). Writing may fail because of this.
- A directory "." means to put the backup file in the same directory
as the edited file.
- A directory starting with "./" (or ".\" for MS-DOS et.al.) means to
put the backup file relative to where the edited file is. The
leading "." is replaced with the path name of the edited file.
("." inside a directory name has no special meaning).
- Spaces after the comma are ignored, other spaces are considered part
of the directory name. To have a space at the start of a directory
name, precede it with a backslash.
- To include a comma in a directory name precede it with a backslash.
- A directory name may end in an '/'.
- Environment variables are expanded |:set_env|.
- Careful with '\' characters, type one before a space, type two to
get one in the option (see |option-backslash|), for example: >
:set bdir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
< - For backwards compatibility with Vim version 3.0 a '>' at the start
of the option is removed.
See also 'backup' and 'writebackup' options.
If you want to hide your backup files on Unix, consider this value: >
:set backupdir=./.backup,~/.backup,.,/tmp
< You must create a ".backup" directory in each directory and in your
home directory for this to work properly.
The use of |:set+=| and |:set-=| is preferred when adding or removing
directories from the list. This avoids problems when a future version
uses another default.
This option cannot be set from a |modeline|, for security reasons.
*'backupext'* *'bex'* *E589*
'backupext' 'bex' string (default "~", for VMS: "_")
global
String which is appended to a file name to make the name of the
backup file. The default is quite unusual, because this avoids
accidentally overwriting existing files with a backup file. You might
prefer using ".bak", but make sure that you don't have files with
".bak" that you want to keep.
*'backupskip'* *'bsk'*
'backupskip' 'bsk' string (default: "/tmp/*,$TMPDIR/*,$TMP/*,$TEMP/*")
global
{not available when compiled without the |+wildignore|
feature}
A list of file patterns. When one of the patterns matches with the
name of the file which is written, no backup file is created. Both
the specified file name and the full path name of the file are used.
The pattern is used like with |:autocmd|, see |autocmd-patterns|.
Watch out for special characters, see |option-backslash|.
When $TMPDIR, $TMP or $TEMP is not defined, it is not used for the
default value. "/tmp/*" is only used for Unix.
*'balloondelay'* *'bdlay'*
'balloondelay' 'bdlay' number (default: 600)
global
{only available when compiled with the |+balloon_eval|
feature}
Delay in milliseconds before a balloon may pop up. See |balloon-eval|.
*'ballooneval'* *'beval'* *'noballooneval'* *'nobeval'*
'ballooneval' 'beval' boolean (default off)
global
{only available when compiled with the |+balloon_eval|
and |+sun_workshop| or |+netbeans_intg| features}
Switch on the |balloon-eval| functionality.
*'binary'* *'bin'* *'nobinary'* *'nobin'*
'binary' 'bin' boolean (default off)
local to buffer
This option should be set before editing a binary file. You can also
use the |-b| Vim argument. When this option is switched on a few
options will be changed (also when it already was on):
'textwidth' will be set to 0
'wrapmargin' will be set to 0
'modeline' will be off
'expandtab' will be off
Also, 'fileformat' and 'fileformats' options will not be used, the
file is read and written like 'fileformat' was "unix" (a single <NL>
separates lines).
The 'fileencoding' and 'fileencodings' options will not be used, the
file is read without conversion.
NOTE: When you start editing a(nother) file while the 'bin' option is
on, settings from autocommands may change the settings again (e.g.,
'textwidth'), causing trouble when editing. You might want to set
'bin' again when the file has been loaded.
The previous values of these options are remembered and restored when
'bin' is switched from on to off. Each buffer has its own set of
saved option values.
When writing a file the <EOL> for the last line is only written if
there was one in the original file (normally Vim appends an <EOL> to
the last line if there is none; this would make the file longer). See
the 'endofline' option.
*'bioskey'* *'biosk'* *'nobioskey'* *'nobiosk'*
'bioskey' 'biosk' boolean (default on)
global
When on the bios is called to obtain a keyboard character. This works
better to detect CTRL-C, but only works for the console. When using a
terminal over a serial port reset this option.
Also see |'conskey'|.
*'bomb'* *'nobomb'*
'bomb' boolean (default off)
local to buffer
{only available when compiled with the |+multi_byte|
feature}
When writing a file and the following conditions are met, a BOM (Byte
Order Mark) is prepended to the file:
- this option is on
- the 'binary' option is off
- 'fileencoding' is "utf-8", "ucs-2", "ucs-4" or one of the little/big
endian variants.
Some applications use the BOM to recognize the encoding of the file.
Often used for UCS-2 files on MS-Windows. For other applications it
causes trouble, for example: "cat file1 file2" makes the BOM of file2
appear halfway the file.
When Vim reads a file and 'fileencodings' starts with "ucs-bom", a
check for the presence of the BOM is done and 'bomb' set accordingly.
Unless 'binary' is set, it is removed from the first line, so that you
don't see it when editing. When you don't change the options, the BOM
will be restored when writing the file.
*'breakat'* *'brk'*
'breakat' 'brk' string (default " ^I!@*-+;:,./?")
global
{not available when compiled without the |+linebreak|
feature}
This option lets you choose which characters might cause a line
break if 'linebreak' is on.
*'browsedir'* *'bsdir'*
'browsedir' 'bsdir' string (default for "last")
global
Which directory to use for the file browser:
last Use same directory as with last file browser.
buffer Use the directory of the related buffer.
current Use the current directory.
{path} Use the specified directory
*'bufhidden'* *'bh'*
'bufhidden' 'bh' string (default: "")
local to buffer
{not available when compiled without the |+quickfix|
feature}
This option specifies what happens when a buffer is no longer
displayed in a window:
<empty> follow the global 'hidden' option
hide hide the buffer (don't unload it), also when 'hidden'
is not set
unload unload the buffer, also when 'hidden' is set or using
|:hide|
delete delete the buffer from the buffer list, also when
'hidden' is set or using |:hide|, like using
|:bdelete|
wipe wipe out the buffer from the buffer list, also when
'hidden' is set or using |:hide|, like using
|:bwipeout|
This option is used together with 'buftype' and 'swapfile' to specify
special kinds of buffers. See |special-buffers|.
*'buflisted'* *'bl'* *E85*
'buflisted' 'bl' boolean (default: on)
local to buffer
When this option is set, the buffer shows up in the buffer list. If
it is reset it is not used for ":bnext", "ls", the Buffers menu, etc.
This option is reset by Vim for buffers that are only used to remember
a file name or marks. Vim sets it when starting to edit a buffer.
But not when moving to a buffer with ":buffer".
*'buftype'* *'bt'* *E382*
'buftype' 'bt' string (default: "")
local to buffer
{not available when compiled without the |+quickfix|
feature}
The value of this option specifies the type of a buffer:
<empty> normal buffer
nofile buffer which is not related to a file and will not be
written
nowrite buffer which will not be written
quickfix quickfix buffer, contains list of errors |:cwindow|
help help buffer (you are not supposed to set this
manually)
This option is used together with 'bufhidden' and 'swapfile' to
specify special kinds of buffers. See |special-buffers|.
Be careful with changing this option, it can have many side effects!
A "quickfix" buffer is only used for the error list. This value is
set by the |:cwindow| command and you are not supposed to change it.
"nofile" and "nowrite" buffers are similar:
both: The buffer is not to be written to disk, ":w" doesn't
work (":w filename" does work though).
both: The buffer is never considered to be |'modified'|.
There is no warning when the changes will be lost, for
example when you quit Vim.
both: A swap file is only created when using too much memory
(when 'swapfile' has been reset there is never a swap
file).
nofile only: The buffer name is fixed, it is not handled like a
file name. It is not modified in response to a |:cd|
command.
*'casemap'* *'cmp'*
'casemap' 'cmp' string (default: "internal,keepascii")
global
Specifies details about changing the case of letters. It may contain
these words, separated by a comma:
internal Use internal case mapping functions, the current
locale does not change the case mapping. This only
matters when 'encoding' is a Unicode encoding. When
"internal" is omitted, the towupper() and towlower()
system library functions are used when available.
keepascii For the ASCII characters (0x00 to 0x7f) use the US
case mapping, the current locale is not effective.
This probably only matters for Turkish.
*'cdpath'* *'cd'* *E344* *E346*
'cdpath' 'cd' string (default: equivalent to $CDPATH or ",,")
global
{not available when compiled without the
|+file_in_path| feature}
This is a list of directories which will be searched when using the
|:cd| and |:lcd| commands, provided that the directory being searched
for has a relative path (not starting with "/", "./" or "../").
The 'cdpath' option's value has the same form and semantics as
|'path'|. Also see |file-searching|.
The default value is taken from $CDPATH, with a "," prepended to look
in the current directory first.
If the default value taken from $CDPATH is not what you want, include
a modified version of the following command in your vimrc file to
override it: >
:let &cdpath = ',' . substitute(substitute($CDPATH, '[, ]', '\\\0', 'g'), ':', ',', 'g')
< This option cannot be set from a |modeline|, for security reasons
(parts of 'cdpath' can be passed to the shell to expand file names).
*'cedit'*
'cedit' string (Vi default: "", Vim default: CTRL-F)
global
{not available when compiled without the |+vertsplit|
feature}
The key used in Command-line Mode to open the command-line window.
The default is CTRL-F when 'compatible' is off.
Only non-printable keys are allowed.
The key can be specified as a single character, but it is difficult to
type. The preferred way is to use the <> notation. Examples: >
:set cedit=<C-Y>
:set cedit=<Esc>
< |Nvi| also has this option, but it only uses the first character.
See |cmdwin|.
*'charconvert'* *'ccv'* *E202* *E214* *E513*
'charconvert' 'ccv' string (default "")
global
{only available when compiled with the |+multi_byte|
feature and the |+eval| feature}
An expression that is used for character encoding conversion. It is
evaluated when a file that is to be read or has been written has a
different encoding from what is desired.
'charconvert' is not used when the internal iconv() function is
supported and is able to do the conversion. Using iconv() is
preferred, because it is much faster.
'charconvert' is not used when reading stdin |--|, because there is no
file to convert from. You will have to save the text in a file first.
The expression must return zero or an empty string for success,
non-zero for failure.
The possible encoding names encountered are in 'encoding'.
Additionally, names given in 'fileencodings' and 'fileencoding' are
used.
Conversion between "latin1", "unicode", "ucs-2", "ucs-4" and "utf-8"
is done internally by Vim, 'charconvert' is not used for this.
'charconvert' is also used to convert the viminfo file, if the 'c'
flag is present in 'viminfo'. Also used for Unicode conversion.
Example: >
set charconvert=CharConvert()
fun CharConvert()
system("recode "
\ . v:charconvert_from . ".." . v:charconvert_to
\ . " <" . v:fname_in . " >" v:fname_out)
return v:shell_error
endfun
< The related Vim variables are:
v:charconvert_from name of the current encoding
v:charconvert_to name of the desired encoding
v:fname_in name of the input file
v:fname_out name of the output file
Note that v:fname_in and v:fname_out will never be the same.
Note that v:charconvert_from and v:charconvert_to may be different
from 'encoding'. Vim internally uses UTF-8 instead of UCS-2 or UCS-4.
Encryption is not done by Vim when using 'charconvert'. If you want
to encrypt the file after conversion, 'charconvert' should take care
of this.
This option cannot be set from a |modeline|, for security reasons.
*'cindent'* *'cin'* *'nocindent'* *'nocin'*
'cindent' 'cin' boolean (default off)
local to buffer
{not available when compiled without the |+cindent|
feature}
Enables automatic C program indenting See 'cinkeys' to set the keys
that trigger reindenting in insert mode and 'cinoptions' to set your
preferred indent style.
If 'indentexpr' is not empty, it overrules 'cindent'.
If 'lisp' is not on and both 'indentexpr' and 'equalprg' are empty,
the "=" operator indents using this algorithm rather than calling an
external program.
See |C-indenting|.
When you don't like the way 'cindent' works, try the 'smartindent'
option or 'indentexpr'.
This option is not used when 'paste' is set.
NOTE: This option is reset when 'compatible' is set.
*'cinkeys'* *'cink'*
'cinkeys' 'cink' string (default "0{,0},0),:,0#,!^F,o,O,e")
local to buffer
{not available when compiled without the |+cindent|
feature}
A list of keys that, when typed in Insert mode, cause reindenting of
the current line. Only used if 'cindent' is on and 'indentexpr' is
empty.
For the format of this option see |cinkeys-format|.
See |C-indenting|.
*'cinoptions'* *'cino'*
'cinoptions' 'cino' string (default "")
local to buffer
{not available when compiled without the |+cindent|
feature}
The 'cinoptions' affect the way 'cindent' reindents lines in a C
program. See |cinoptions-values| for the values of this option, and
|C-indenting| for info on C indenting in general.
*'cinwords'* *'cinw'*
'cinwords' 'cinw' string (default "if,else,while,do,for,switch")
local to buffer
{not available when compiled without both the
|+cindent| and the |+smartindent| features}
These keywords start an extra indent in the next line when
'smartindent' or 'cindent' is set. For 'cindent' this is only done at
an appropriate place (inside {}).
Note that 'ignorecase' isn't used for 'cinwords'. If case doesn't
matter, include the keyword both the uppercase and lowercase:
"if,If,IF".
*'clipboard'* *'cb'*
'clipboard' 'cb' string (default "autoselect,exclude:cons\|linux"
for X-windows, "" otherwise)
global
{only in GUI versions or when the |+xterm_clipboard|
feature is included}
This option is a list of comma separated names.
These names are recognized:
unnamed When included, Vim will use the clipboard register '*'
for all yank, delete, change and put operations which
would normally go to the unnamed register. When a
register is explicitly specified, it will always be
used regardless of whether "unnamed" is in 'clipboard'
or not. The clipboard register can always be
explicitly accessed using the "* notation. Also see
|gui-clipboard|.
autoselect Works like the 'a' flag in 'guioptions': If present,
then whenever Visual mode is started, or the Visual
area extended, Vim tries to become the owner of the
windowing system's global selection or put the
selected text on the clipboard used by the selection
register "*. See |guioptions_a| and |quotestar| for
details. When the GUI is active, the 'a' flag in
'guioptions' is used, when the GUI is not active, this
"autoselect" flag is used.
Also applies to the modeless selection.
autoselectml Like "autoselect", but for the modeless selection
only. Compare to the 'A' flag in 'guioptions'.
exclude:{pattern}
Defines a pattern that is matched against the name of
the terminal 'term'. If there is a match, no
connection will be made to the X server. This is
useful in this situation:
- Running Vim in a console.
- $DISPLAY is set to start applications on another
display.
- You do not want to connect to the X server in the
console, but do want this in a terminal emulator.
To never connect to the X server use: >
exclude:.*
< This has the same effect as using the |-X| argument.
Note that when there is no connection to the X server
the window title won't be restored and the clipboard
cannot be accessed.
The value of 'magic' is ignored, {pattern} is
interpreted as if 'magic' was on.
The rest of the option value will be used for
{pattern}, this must be the last entry.
*'cmdheight'* *'ch'*
'cmdheight' 'ch' number (default 1)
global
Number of screen lines to use for the command-line. Helps avoiding
|hit-enter| prompts.
*'cmdwinheight'* *'cwh'*
'cmdwinheight' 'cwh' number (default 7)
global
{not available when compiled without the |+vertsplit|
feature}
Number of screen lines to use for the command-line window. |cmdwin|
*'columns'* *'co'* *E594*
'columns' 'co' number (default 80 or terminal width)
global
Number of columns of the screen. Normally this is set by the terminal
initialization and does not have to be set by hand.
When Vim is running in the GUI or in a resizable window, setting this
option will cause the window size to be changed. When you only want
to use the size for the GUI, put the command in your |gvimrc| file.
When you set this option and Vim is unable to change the physical
number of columns of the display, the display may be messed up.
*'comments'* *'com'* *E524* *E525*
'comments' 'com' string (default
"s1:/*,mb:*,ex:*/,://,b:#,:%,:XCOMM,n:>,fb:-")
local to buffer
{not available when compiled without the |+comments|
feature}
A comma separated list of strings that can start a comment line. See
|format-comments|. See |option-backslash| about using backslashes to
insert a space.
*'commentstring'* *'cms'* *E537*
'commentstring' 'cms' string (default "/*%s*/")
local to buffer
{not available when compiled without the |+folding|
feature}
A template for a comment. The "%s" in the value is replaced with the
comment text. Currently only used to add markers for folding, see
|fold-marker|.
*'compatible'* *'cp'* *'nocompatible'* *'nocp'*
'compatible' 'cp' boolean (default on, off when a .vimrc file is found)
global
This option has the effect of making Vim either more Vi-compatible, or
make Vim behave in a more useful way.
This is a special kind of option, because when it's set or reset,
other options are also changed as a side effect. CAREFUL: Setting or
resetting this option can have a lot of unexpected effects: Mappings
are interpreted in another way, undo behaves differently, etc. If you
set this option in your vimrc file, you should probably put it at the
very start.
By default this option is on and the Vi defaults are used for the
options. This default was chosen for those people who want to use Vim
just like Vi, and don't even (want to) know about the 'compatible'
option.
When a ".vimrc" file is found while Vim is starting up, this option is
switched off, and all options that have not been modified will be set
to the Vim defaults. Effectively, this means that when a ".vimrc"
file exists, Vim will use the Vim defaults, otherwise it will use the
Vi defaults. (Note: This doesn't happen for the system-wide vimrc
file). Also see |compatible-default|.
You can also set this option with the "-C" argument, and reset it with
"-N". See |-C| and |-N|.
Switching this option off makes the Vim defaults be used for options
that have a different Vi and Vim default value. See the options
marked with a '+' below. Other options are not modified.
At the moment this option is set, several other options will be set
or reset to make Vim as Vi-compatible as possible. See the table
below. This can be used if you want to revert to Vi compatible
editing.

*'complete'* *'cpt'* *E535*
'complete' 'cpt' string (default: ".,w,b,u,t,i")
local to buffer
This option specifies how keyword completion |ins-completion| works
when CTRL-P or CTRL-N are used. It is also used for whole-line
completion |i_CTRL-X_CTRL-L|. It indicates the type of completion
and the places to scan. It is a comma separated list of flags:
. scan the current buffer ('wrapscan' is ignored)
w scan buffers from other windows
b scan other loaded buffers that are in the buffer list
u scan the unloaded buffers that are in the buffer list
U scan the buffers that are not in the buffer list
k scan the files given with the 'dictionary' option
k{dict} scan the file {dict}. Several "k" flags can be given,
patterns are valid too. For example: >
:set cpt=k/usr/dict/*,k~/spanish
< s scan the files given with the 'thesaurus' option
s{tsr} scan the file {tsr}. Several "s" flags can be given, patterns
are valid too.
i scan current and included files
d scan current and included files for defined name or macro
|i_CTRL-X_CTRL-D|
] tag completion
t same as "]"
Unloaded buffers are not loaded, thus their autocmds |:autocmd| are
not executed, this may lead to unexpected completions from some files
(gzipped files for example). Unloaded buffers are not scanned for
whole-line completion.
The default is ".,w,b,u,t,i", which means to scan:
1. the current buffer
2. buffers in other windows
3. other loaded buffers
4. unloaded buffers
5. tags
6. included files
As you can see, CTRL-N and CTRL-P can be used to do any 'iskeyword'-
based expansion (eg dictionary |i_CTRL-X_CTRL-K|, included patterns
|i_CTRL-X_CTRL-I|, tags |i_CTRL-X_CTRL-]| and normal expansions)
*'confirm'* *'cf'* *'noconfirm'* *'nocf'*
'confirm' 'cf' boolean (default off)
global
When 'confirm' is on, certain operations that would normally
fail because of unsaved changes to a buffer, e.g. ":q" and ":e",
instead raise a |dialog| asking if you wish to save the current
file(s). You can still use a ! to unconditionally |abandon| a buffer.
If 'confirm' is off you can still activate confirmation for one
command only (this is most useful in mappings) with the |:confirm|
command.
Also see the |confirm()| function and the 'v' flag in 'guioptions'.
*'conskey'* *'consk'* *'noconskey'* *'noconsk'*
'conskey' 'consk' boolean (default off)
global
When on direct console I/O is used to obtain a keyboard character.
This should work in most cases. Also see |'bioskey'|. Together,
three methods of console input are available:
'conskey' 'bioskey' action ~
on on or off direct console input
off on BIOS
off off STDIN
*'copyindent'* *'ci'* *'nocopyindent'* *'noci'*
'copyindent' 'ci' boolean (default off)
local to buffer
Copy the structure of the existing lines indent when autoindenting a
new line. Normally the new indent is reconstructed by a series of
tabs followed by spaces as required (unless |'expandtab'| is enabled,
in which case only spaces are used). Enabling this option makes the
new line copy whatever characters were used for indenting on the
existing line. If the new indent is greater than on the existing
line, the remaining space is filled in the normal manner.
NOTE: 'copyindent' is reset when 'compatible' is set.
Also see 'preserveindent'.
*'cpoptions'* *'cpo'*
'cpoptions' 'cpo' string (Vim default: "aABceFs",
Vi default: all flags)
global
A sequence of single character flags. When a character is present
this indicates vi-compatible behavior. This is used for things where
not being vi-compatible is mostly or sometimes preferred.
'cpoptions' stands for "compatible-options".
Commas can be added for readability.
To avoid problems with flags that are added in the future, use the
"+=" and "-=" feature of ":set" |add-option-flags|.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
contains behavior ~
*cpo-a*
a When included, a ":read" command with a file name
argument will set the alternate file name for the
current window.
*cpo-A*
A When included, a ":write" command with a file name
argument will set the alternate file name for the
current window.
*cpo-b*
b "\|" in a ":map" command is recognized as the end of
the map command. The '\' is included in the mapping,
the text after the '|' is interpreted as the next
command. Use a CTRL-V instead of a backslash to
include the '|' in the mapping. Applies to all
mapping, abbreviation, menu and autocmd commands.
See also |map_bar|.
*cpo-B*
B A backslash has no special meaning in mappings,
abbreviations and the "to" part of the menu commands.
Remove this flag to be able to use a backslash like a
CTRL-V. For example, the command ":map X \<Esc>"
results in X being mapped to:
'B' included: "\^[" (^[ is a real <Esc>)
'B' excluded: "<Esc>" (5 characters)
('<' excluded in both cases)
*cpo-c*
c Searching continues at the end of any match at the
cursor position. When not present searching continues
one character from the cursor position. With 'c'
"abababababab" only gets three matches when repeating
"/abab", without 'c' there are five matches.
*cpo-C*
C Do not concatenate sourced lines that start with a
backslash. See |line-continuation|.
*cpo-d*
d Using "./" in the 'tags' option doesn't mean to use
the tags file relative to the current file, but the
tags file in the current directory.
*cpo-D*
D Can't use CTRL-K to enter a digraph after Normal mode
commands with a character argument, like |r|, |f| and
|t|.
*cpo-e*
e When executing a register with ":@r", always add a
<CR> to the last line, also when the register is not
linewise. If this flag is not present, the register
is not linewise and the last line does not end in a
<CR>, then the last line is put on the command-line
and can be edited before hitting <CR>.
*cpo-E*
E It is an error when using "y", "d", "c", "g~", "gu" or
"gU" on an Empty region. The operators only work when
at least one character is to be operate on. Example:
This makes "y0" fail in the first column.
*cpo-f*
f When included, a ":read" command with a file name
argument will set the file name for the current buffer,
if the current buffer doesn't have a file name yet.
*cpo-F*
F When included, a ":write" command with a file name
argument will set the file name for the current
buffer, if the current buffer doesn't have a file name
yet.
*cpo-g*
g Goto line 1 when using ":edit" without argument.
*cpo-i*
i When included, interrupting the reading of a file will
leave it modified.
*cpo-j*
j When joining lines, only add two spaces after a '.',
not after '!' or '?'. Also see 'joinspaces'.
*cpo-J*
J A |sentence| has to be followed by two spaces after
the '.', '!' or '?'. A <Tab> is not recognized as
white space.
*cpo-k*
k Disable the recognition of raw key codes in
mappings, abbreviations, and the "to" part of menu
commands. For example, if <Key> sends ^[OA (where ^[
is <Esc>), the command ":map X ^[OA" results in X
being mapped to:
'k' included: "^[OA" (3 characters)
'k' excluded: "<Key>" (one key code)
Also see the '<' flag below.
*cpo-K*
K Don't wait for a key code to complete when it is
halfway a mapping. This breaks mapping <F1><F1> when
only part of the second <F1> has been read. It
enables cancelling the mapping by typing <F1><Esc>.
*cpo-l*
l Backslash in a [] range in a search pattern is taken
literally, only "\]" is special See |/[]|
'l' included: "/[ \t]" finds <Space>, '\' and 't'
'l' excluded: "/[ \t]" finds <Space> and <Tab>
*cpo-L*
L When the 'list' option is set, 'wrapmargin',
'textwidth' and Virtual Replace mode (see |gR|) count
a <Tab> as two characters, instead of the normal
behavior of a <Tab>.
*cpo-m*
m When included, a showmatch will always wait half a
second. When not included, a showmatch will wait half
a second or until a character is typed. |'showmatch'|
*cpo-M*
M When excluded, "%" matching will take backslashes into
account. Thus in "( \( )" and "\( ( \)" the outer
parenthesis match. When included "%" ignores
backslashes, which is Vi compatible.
*cpo-n*
n When included, the column used for 'number' will also
be used for text of wrapped lines.
*cpo-o*
o Line offset to search command is not remembered for
next search.
*cpo-O*
O Don't complain if a file is being overwritten, even
when it didn't exist when editing it. This is a
protection against a file unexpectedly created by
someone else. Vi didn't complain about this.
*cpo-p*
p Vi compatible Lisp indenting. When not present, a
slightly better algorithm is used.
*cpo-r*
r Redo ("." command) uses "/" to repeat a search
command, instead of the actually used search string.
*cpo-s*
s Set buffer options when entering the buffer for the
first time. This is like it is in Vim version 3.0.
And it is the default. If not present the options are
set when the buffer is created.
*cpo-S*
S Set buffer options always when entering a buffer
(except 'readonly', 'fileformat', 'filetype' and
'syntax'). This is the (most) Vi compatible setting.
The options are set to the values in the current
buffer. When you change an option and go to another
buffer, the value is copied. Effectively makes the
buffer options global to all buffers.
's' 'S' copy buffer options
no no when buffer created
yes no when buffer first entered (default)
X yes each time when buffer entered (vi comp.)
*cpo-t*
t Search pattern for the tag command is remembered for
"n" command. Otherwise Vim only puts the pattern in
the history for search pattern, but doesn't change the
last used search pattern.
*cpo-u*
u Undo is Vi compatible. See |undo-two-ways|.
*cpo-v*
v Backspaced characters remain visible on the screen in
Insert mode. Without this flag the characters are
erased from the screen right away. With this flag the
screen newly typed text overwrites backspaced
characters.
*cpo-w*
w When using "cw" on a blank character, only change one
character and not all blanks until the start of the
next word.
*cpo-W*
W Don't overwrite a readonly file. When omitted, ":w!"
overwrites a readonly file, if possible.
*cpo-x*
x <Esc> on the command-line executes the command-line.
The default in Vim is to abandon the command-line,
because <Esc> normally aborts a command. |c_<Esc>|
*cpo-y*
y A yank command can be redone with ".".
*cpo-!*
! When redoing a filter command, use the last used
external command, whatever it was. Otherwise the last
used -filter- command is used.
*cpo-$*
$ When making a change to one line, don't redisplay the
line, but put a '$' at the end of the changed text.
The changed text will be overwritten when you type the
new text. The line is redisplayed if you type any
command that moves the cursor from the insertion
point.
*cpo-%*
% Vi-compatible matching is done for the "%" command.
Does not recognize "#if", "#endif", etc.
Does not recognize "/*" and "*/".
Parens inside single and double quotes are also
counted, causing a string that contains a paren to
disturb the matching. For example, in a line like
"if (strcmp("foo(", s))" the first paren does not
match the last one. When this flag is not included,
parens inside single and double quotes are treated
specially. When matching a paren outside of quotes,
everything inside quotes is ignored. When matching a
paren inside quotes, it will find the matching one (if
there is one). This works very well for C programs.
*cpo-star*
* Use ":*" in the same way as ":@". When not included,
":*" is an alias for ":'<,'>", select the Visual area.
*cpo-<*
< Disable the recognition of special key codes in |<>|
form in mappings, abbreviations, and the "to" part of
menu commands. For example, the command
":map X <Tab>" results in X being mapped to:
'<' included: "<Tab>" (5 characters)
'<' excluded: "^I" (^I is a real <Tab>)
Also see the 'k' flag above.
*'cscopepathcomp'* *'cspc'*
'cscopepathcomp' 'cspc' number (default 0)
global
{not available when compiled without the |+cscope|
feature}
Determines how many components of the path to show in a list of tags.
See |cscopepathcomp|.
*'cscopeprg'* *'csprg'*
'cscopeprg' 'csprg' string (default "cscope")
global
{not available when compiled without the |+cscope|
feature}
Specifies the command to execute cscope. See |cscopeprg|.
This option cannot be set from a |modeline|, for security reasons.
*'cscopequickfix'* *'csqf'*
'cscopequickfix' 'csqf' string (default "")
global
{not available when compiled without the |+cscope|
or |+quickfix| features}
Specifies whether to use quickfix window to show cscope results.
See |cscopequickfix|.
*'cscopetag'* *'cst'* *'nocscopetag'* *'nocst'*
'cscopetag' 'cst' boolean (default off)
global
{not available when compiled without the |+cscope|
feature}
Use cscope for tag commands. See |cscope-options|.
NOTE: This option is reset when 'compatible' is set.
*'cscopetagorder'* *'csto'*
'cscopetagorder' 'csto' number (default 0)
global
{not available when compiled without the |+cscope|
feature}
Determines the order in which ":cstag" performs a search. See
|cscopetagorder|.
NOTE: This option is set to 0 when 'compatible' is set.
*'cscopeverbose'* *'csverb'*
*'nocscopeverbose'* *'nocsverb'*
'cscopeverbose' 'csverb' boolean (default off)
global
{not available when compiled without the |+cscope|
feature}
Give messages when adding a cscope database. See |cscopeverbose|.
NOTE: This option is reset when 'compatible' is set.
*'debug'*
'debug' string (default "")
global
When set to "msg", error messages that would otherwise be omitted will
be given anyway. This is useful when debugging 'foldexpr' or
'indentexpr'.
*'define'* *'def'*
'define' 'def' string (default "^#\s*define")
global or local to buffer |global-local|
Pattern to be used to find a macro definition. It is a search
pattern, just like for the "/" command. This option is used for the
commands like "[i" and "[d" |include-search|. The 'isident' option is
used to recognize the defined name after the match:
{match with 'define'}{non-ID chars}{defined name}{non-ID char}
See |option-backslash| about inserting backslashes to include a space
or backslash.
The default value is for C programs. For C++ this value would be
useful, to include const type declarations: >
^\(#\s*define\|[a-z]*\s*const\s*[a-z]*\)
< When using the ":set" command, you need to double the backslashes!
*'delcombine'* *'deco'*
'delcombine' 'deco' boolean (default off)
global
{only available when compiled with the |+multi_byte|
feature}
If editing Unicode and this option is set, backspace and Normal mode
"x" delete each combining character on its own. When it is off (the
default) the character along with its combining characters are
deleted.
Note: When 'delcombine' is set "xx" may work different from "2x"!
This is useful for Arabic, Hebrew and many other languages where one
may have combining characters overtop of base characters, and want
to remove only the combining ones.
*'dictionary'* *'dict'*
'dictionary' 'dict' string (default "")
global or local to buffer |global-local|
List of file names, separated by commas, that are used to lookup words
for keyword completion commands |i_CTRL-X_CTRL-K|. Each file should
contain a list of words. This can be one word per line, or several
words per line, separated by non-keyword characters (white space is
preferred). Maximum line length is 510 bytes.
To include a comma in a file name precede it with a backslash. Spaces
after a comma are ignored, otherwise spaces are included in the file
name. See |option-backslash| about using backslashes.
Where to find a list of words?
- On FreeBSD, there is the file "/usr/share/dict/words".
- In the Simtel archive, look in the "msdos/linguist" directory.
- In "miscfiles" of the GNU collection.
The use of |:set+=| and |:set-=| is preferred when adding or removing
directories from the list. This avoids problems when a future version
uses another default.
Backticks cannot be used in this option for security reasons.
*'diff'* *'nodiff'*
'diff' boolean (default off)
local to window
{not available when compiled without the |+diff|
feature}
Join the current window in the group of windows that shows differences
between files. See |vimdiff|.
*'dex'* *'diffexpr'*
'diffexpr' 'dex' string (default "")
global
{not available when compiled without the |+diff|
feature}
Expression which is evaluated to obtain an ed-style diff file from two
versions of a file. See |diff-diffexpr|.
This option cannot be set from a |modeline|, for security reasons.
*'dip'* *'diffopt'*
'diffopt' 'dip' string (default "filler")
global
{not available when compiled without the |+diff|
feature}
Option settings for diff mode. It can consist of the following items.
All are optional. Items must be separated by a comma.
filler Show filler lines, to keep the text
synchronized with a window that has inserted
lines at the same position. Mostly useful
when windows are side-by-side and 'scrollbind'
is set.
context:{n} Use a context of {n} lines between a change
and a fold that contains unchanged lines.
When omitted a context of six lines is used.
See |fold-diff|.
icase Ignore changes in case of text. "a" and "A"
are considered the same. Adds the "-i" flag
to the "diff" command if 'diffexpr' is empty.
iwhite Ignore changes in amount of white space. Adds
the "-b" flag to the "diff" command if
'diffexpr' is empty. Check the documentation
of the "diff" command for what this does
exactly. It should ignore adding trailing
white space, but not leading white space.
Examples: >
:set diffopt=filler,context:4
:set diffopt=
:set diffopt=filler
<
-->
*'digraph'* *'dg'* *'nodigraph'* *'nodg'*
'digraph' 'dg' boolean (default off)
global
Enable the entering of digraphs in Insert mode with {char1} <BS>
{char2}. See |digraphs|.
<!--
*'directory'* *'dir'*
'directory' 'dir' string (default for Amiga: ".,t:",
for MS-DOS and Win32: ".,c:\tmp,c:\temp"
for Unix: ".,~/tmp,/var/tmp,/tmp")
global
List of directory names for the swap file, separated with commas.
- The swap file will be created in the first directory where this is
possible.
- Empty means that no swap file will be used (recovery is
impossible!).
- A directory "." means to put the swap file in the same directory as
the edited file. On Unix, a dot is prepended to the file name, so
it doesn't show in a directory listing.
- A directory starting with "./" (or ".\" for MS-DOS et.al.) means to
put the swap file relative to where the edited file is. The leading
"." is replaced with the path name of the edited file.
- For Unix and Win32, if a directory ends in two path separators, the
swap file name will be built from the complete path to the file
with all path separators substituted to percent '%' signs. This will
ensure file name uniqueness in the preserve directory.
- Spaces after the comma are ignored, other spaces are considered part
of the directory name. To have a space at the start of a directory
name, precede it with a backslash.
- To include a comma in a directory name precede it with a backslash.
- A directory name may end in an ':' or '/'.
- Environment variables are expanded |:set_env|.
- Careful with '\' characters, type one before a space, type two to
get one in the option (see |option-backslash|), for example: >
:set dir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
< - For backwards compatibility with Vim version 3.0 a '>' at the start
of the option is removed.
Using "." first in the list is recommended. This means that editing
the same file twice will result in a warning. Using "/tmp" on Unix is
discouraged: When the system crashes you lose the swap file.
"/var/tmp" is often not cleared when rebooting, thus is a better
choice than "/tmp". But it can contain a lot of files, your swap
files get lost in the crowd. That is why a "tmp" directory in your
home directory is tried first.
The use of |:set+=| and |:set-=| is preferred when adding or removing
directories from the list. This avoids problems when a future version
uses another default.
This option cannot be set from a |modeline|, for security reasons.
{Vi: directory to put temp file in, defaults to "/tmp"}
*'display'* *'dy'*
'display' 'dy' string (default "")
global
Change the way text is displayed. This is comma separated list of
flags:
lastline When included, as much as possible of the last line
in a window will be displayed. When not included, a
last line that doesn't fit is replaced with "@" lines.
uhex Show unprintable characters hexadecimal as <xx>
instead of using ^C and ~C.
*'eadirection'* *'ead'*
'eadirection' 'ead' string (default "both")
global
{not available when compiled without the +vertsplit
feature}
Tells when the 'equalalways' option applies:
ver vertically, width of windows is not affected
hor horizontally, height of windows is not affected
both width and height of windows is affected
*'ed'* *'edcompatible'* *'noed'* *'noedcompatible'*
'edcompatible' 'ed' boolean (default off)
global
Makes the 'g' and 'c' flags of the ":substitute" command to be
toggled each time the flag is given. See |complex-change|. See
also 'gdefault' option.
Switching this option on is discouraged!
*'encoding'* *'enc'* *E543*
'encoding' 'enc' string (default: "latin1" or value from $LANG)
global
{only available when compiled with the |+multi_byte|
feature}
Sets the character encoding used inside Vim. It applies to text in
the buffers, registers, Strings in expressions, text stored in the
viminfo file, etc. It sets the kind of characters which Vim can work
with. See |encoding-names| for the possible values.
NOTE: Changing this option will not change the encoding of the
existing text in Vim. It may cause multi-byte text to become invalid.
It should normally be kept at its default value, or set when Vim
starts up. See |multibyte|.
NOTE: For GTK+ 2 it is highly recommended to set 'encoding' to
"utf-8". Although care has been taken to allow different values of
'encoding', "utf-8" is the natural choice for the environment and
avoids unnecessary conversion overhead. "utf-8" has not been made
the default to prevent different behaviour of the GUI and terminal
versions, and to avoid changing the encoding of newly created files
without your knowledge (in case 'fileencodings' is empty).
The character encoding of files can be different from 'encoding'.
This is specified with 'fileencoding'. The conversion is done with
iconv() or as specified with 'charconvert'.
Normally 'encoding' will be equal to your current locale. This will
be the default if Vim recognizes your environment settings. If
'encoding' is not set to the current locale, 'termencoding' must be
set to convert typed and displayed text. See |encoding-table|.
When you set this option, it fires the |EncodingChanged| autocommand
event so that you can set up fonts if necessary.
When the option is set, the value is converted to lowercase. Thus
you can set it with uppercase values too. Underscores are translated
to '-' signs.
When the encoding is recognized, it is changed to the standard name.
For example "Latin-1" becomes "latin1", "ISO_88592" becomes
"iso-8859-2" and "utf8" becomes "utf-8".
Note: "latin1" is also used when the encoding could not be detected.
This only works when editing files in the same encoding! When the
actual characterset is not latin1, make sure 'fileencoding' and
'fileencodings' are empty. When conversion is needed, switch to using
utf-8.
When "unicode", "ucs-2" or "ucs-4" is used, Vim internally uses utf-8.
You don't notice this while editing, but it does matter for the
|viminfo-file|. And Vim expects the terminal to use utf-8 too. Thus
setting 'encoding' to one of these values instead of utf-8 only has
effect for encoding used for files when 'fileencoding' is empty.
When 'encoding' is set to a Unicode encoding, and 'fileencodings' was
not set yet, the default for 'fileencodings' is changed.
*'endofline'* *'eol'* *'noendofline'* *'noeol'*
'endofline' 'eol' boolean (default on)
local to buffer
When writing a file and this option is off and the 'binary' option
is on, no <EOL> will be written for the last line in the file. This
option is automatically set when starting to edit a new file, unless
the file does not have an <EOL> for the last line in the file, in
which case it is reset. Normally you don't have to set or reset this
option. When 'binary' is off the value is not used when writing the
file. When 'binary' is on it is used to remember the presence of a
<EOL> for the last line in the file, so that when you write the file
the situation from the original file can be kept. But you can change
it if you want to.
*'equalalways'* *'ea'* *'noequalalways'* *'noea'*
'equalalways' 'ea' boolean (default on)
global
When on, all the windows are automatically made the same size after
splitting or closing a window. When off, splitting a window will
reduce the size of the current window and leave the other windows the
same. When closing a window the extra lines are given to the window
next to it (depending on 'splitbelow' and 'splitright').
When mixing vertically and horizontally split windows, a minimal size
is computed and some windows may be larger if there is room. The
'eadirection' option tells in which direction the size is affected.
Changing the height of a window can be avoided by setting
'winfixheight'.
*'equalprg'* *'ep'*
'equalprg' 'ep' string (default "")
global or local to buffer |global-local|
External program to use for "=" command. When this option is empty
the internal formatting functions are used ('lisp', 'cindent' or
'indentexpr').
Environment variables are expanded |:set_env|. See |option-backslash|
about including spaces and backslashes.
This option cannot be set from a |modeline|, for security reasons.
*'errorbells'* *'eb'* *'noerrorbells'* *'noeb'*
'errorbells' 'eb' boolean (default off)
global
Ring the bell (beep or screen flash) for error messages. This only
makes a difference for error messages, the bell will be used always
for a lot of errors without a message (e.g., hitting <Esc> in Normal
mode). See 'visualbell' on how to make the bell behave like a beep,
screen flash or do nothing.
*'errorfile'* *'ef'*
'errorfile' 'ef' string (Amiga default: "AztecC.Err",
others: "errors.err")
global
{not available when compiled without the |+quickfix|
feature}
Name of the errorfile for the QuickFix mode (see |:cf|).
When the "-q" command-line argument is used, 'errorfile' is set to the
following argument. See |-q|.
NOT used for the ":make" command. See 'makeef' for that.
Environment variables are expanded |:set_env|.
See |option-backslash| about including spaces and backslashes.
This option cannot be set from a |modeline|, for security reasons.
*'errorformat'* *'efm'*
'errorformat' 'efm' string (default is very long)
global or local to buffer |global-local|
{not available when compiled without the |+quickfix|
feature}
Scanf-like description of the format for the lines in the error file
(see |errorformat|).
*'esckeys'* *'ek'* *'noesckeys'* *'noek'*
'esckeys' 'ek' boolean (Vim default: on, Vi default: off)
global
Function keys that start with an <Esc> are recognized in Insert
mode. When this option is off, the cursor and function keys cannot be
used in Insert mode if they start with an <Esc>. The advantage of
this is that the single <Esc> is recognized immediately, instead of
after one second. Instead of resetting this option, you might want to
try changing the values for 'timeoutlen' and 'ttimeoutlen'. Note that
when 'esckeys' is off, you can still map anything, but the cursor keys
won't work by default.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'eventignore'* *'ei'*
'eventignore' 'ei' string (default "")
global
{not available when compiled without the |+autocmd|
feature}
A list of autocommand event names, which are to be ignored.
When set to "all", all autocommand events are ignored, autocommands
will not be executed.
Otherwise this is a comma separated list of event names. Example: >
:set ei=WinEnter,WinLeave
<
*'expandtab'* *'et'* *'noexpandtab'* *'noet'*
'expandtab' 'et' boolean (default off)
local to buffer
In Insert mode: Use the appropriate number of spaces to insert a
<Tab>. Spaces are used in indents with the '>' and '<' commands and
when 'autoindent' is on. To insert a real tab when 'expandtab' is
on, use CTRL-V<Tab>. See also |:retab| and |ins-expandtab|.
NOTE: This option is reset when 'compatible' is set.
*'exrc'* *'ex'* *'noexrc'* *'noex'*
'exrc' 'ex' boolean (default off)
global
Enables the reading of .vimrc, .exrc and .gvimrc in the current
directory. If you switch this option on you should also consider
setting the 'secure' option (see |initialization|). Using a local
.exrc, .vimrc or .gvimrc is a potential security leak, use with care!
also see |.vimrc| and |gui-init|.
This option cannot be set from a |modeline|, for security reasons.
*'fileencoding'* *'fenc'* *E213*
'fileencoding' 'fenc' string (default: "")
local to buffer
{only available when compiled with the |+multi_byte|
feature}
Sets the character encoding for the file of this buffer.
When 'fileencoding' is different from 'encoding', conversion will be
done when reading and writing the file.
When 'fileencoding' is empty, the same value as 'encoding' will be
used (no conversion when reading or writing a file).
WARNING: Conversion can cause loss of information! When
'encoding' is "utf-8" conversion is most likely done in a way
that the reverse conversion results in the same text. When
'encoding' is not "utf-8" some characters may be lost!
See 'encoding' for the possible values. Additionally, values may be
specified that can be handled by the converter, see
|mbyte-conversion|.
When reading a file 'fileencoding' will be set from 'fileencodings'.
To read a file in a certain encoding it won't work by setting
'fileencoding', use the |++enc| argument.
Prepending "8bit-" and "2byte-" has no meaning here, they are ignored.
When the option is set, the value is converted to lowercase. Thus
you can set it with uppercase values too. '_' characters are
replaced with '-'. If a name is recognized from the list for
'encoding', it is replaced by the standard name. For example
"ISO8859-2" becomes "iso-8859-2".
When this option is set, after starting to edit a file, the 'modified'
option is set, because the file would be different when written.
If you do this in a modeline, you might want to set 'nomodified' to
avoid this.
This option can not be changed when 'modifiable' is off.
*'fe'*
NOTE: Before version 6.0 this option specified the encoding for the
whole of Vim, this was a mistake. Now use 'encoding' instead. The
old short name was 'fe', which is no longer used.
*'fileencodings'* *'fencs'*
'fileencodings' 'fencs' string (default: "ucs-bom", "ucs-bom,utf-8,latin1"
when 'encoding' is set to a Unicode value)
global
{only available when compiled with the |+multi_byte|
feature}
This is a list of character encodings considered when starting to edit
a file. When a file is read, Vim tries to use the first mentioned
character encoding. If an error is detected, the next one in the list
is tried. When an encoding is found that works, 'fileencoding' is set
to it. If all fail, 'fileencoding' is set to an empty string, which
means the value of 'encoding' is used.
WARNING: Conversion can cause loss of information! When
'encoding' is "utf-8" (or one of the other Unicode variants)
conversion is most likely done in a way that the reverse
conversion results in the same text. When 'encoding' is not
"utf-8" special characters may be lost!
For an empty file or a file with only ASCII characters most encodings
will work and the first entry of 'fileencodings' will be used. If you
prefer another encoding use an BufReadPost autocommand event to test
if your preferred encoding is to be used. Example: >
au BufReadPost * if search('\S', 'w') == 0 |
\ set fenc=iso-2022-jp | endif
< This sets 'fileencoding' to "iso-2022-jp" if the file does not contain
non-blank characters.
The special value "ucs-bom" can be used to check for a Unicode BOM
(Byte Order Mark) at the start of the file. It must not be preceded
by "utf-8" or another Unicode encoding for this to work properly.
An entry for an 8-bit encoding (e.g., "latin1") should be the last,
because Vim cannot detect an error, thus the encoding is always
accepted.
WRONG VALUES: WHAT'S WRONG:
latin1,utf-8 "latin1" will always be used
utf-8,ucs-bom,latin1 BOM won't be recognized in an utf-8
file
cp1250,latin1 "cp1252" will always be used
If 'fileencodings' is empty, 'fileencoding' is not modified.
See 'fileencoding' for the possible values.
Setting this option does not have an effect until the next time a file
is read.
*'fileformat'* *'ff'*
'fileformat' 'ff' string (MS-DOS, MS-Windows, OS/2 default: "dos",
Unix default: "unix",
Macintosh default: "mac")
local to buffer
This gives the <EOL> of the current buffer, which is used for
reading/writing the buffer from/to a file:
dos <CR> <NL>
unix <NL>
mac <CR>
When "dos" is used, CTRL-Z at the end of a file is ignored.
See |file-formats| and |file-read|.
For the character encoding of the file see 'fileencoding'.
When 'binary' is set, the value of 'fileformat' is ignored, file I/O
works like it was set to "unix'.
This option is set automatically when starting to edit a file and
'fileformats' is not empty and 'binary' is off.
When this option is set, after starting to edit a file, the 'modified'
option is set, because the file would be different when written.
This option can not be changed when 'modifiable' is off.
For backwards compatibility: When this option is set to "dos",
'textmode' is set, otherwise 'textmode' is reset.
*'fileformats'* *'ffs'*
'fileformats' 'ffs' string (default:
Vim+Vi MS-DOS, MS-Windows OS/2: "dos,unix",
Vim Unix: "unix,dos",
Vim Mac: "mac,unix,dos",
Vi Cygwin: "unix,dos",
Vi others: "")
global
This gives the end-of-line (<EOL>) formats that will be tried. It is
used when starting to edit a new buffer and when reading a file into
an existing buffer:
- When empty, the format defined with 'fileformat' will be used
always. It is not set automatically.
- When set to one name, that format will be used whenever a new buffer
is opened. 'fileformat' is set accordingly for that buffer. The
'fileformats' name will be used when a file is read into an existing
buffer, no matter what 'fileformat' for that buffer is set to.
- When more than one name is present, separated by commas, automatic
<EOL> detection will be done when reading a file. When starting to
edit a file, a check is done for the <EOL>:
1. If all lines end in <CR><NL>, and 'fileformats' includes "dos",
'fileformat' is set to "dos".
2. If a <NL> is found and 'fileformats' includes "unix", 'fileformat'
is set to "unix". Note that when a <NL> is found without a
preceding <CR>, "unix" is preferred over "dos".
3. If 'fileformats' includes "mac", 'fileformat' is set to "mac".
This means that "mac" is only chosen when "unix" is not present,
or when no <NL> is found in the file, and when "dos" is not
present, or no <CR><NL> is present in the file.
Also if "unix" was first chosen, but the first <CR> is before
the first <NL> and there appears to be more <CR>'s than <NL>'s in
the file, then 'fileformat' is set to "mac".
4. If 'fileformat' is still not set, the first name from
'fileformats' is used.
When reading a file into an existing buffer, the same is done, but
this happens like 'fileformat' has been set appropriately for that
file only, the option is not changed.
When 'binary' is set, the value of 'fileformats' is not used.
For systems with a Dos-like <EOL> (<CR><NL>), when reading files that
are ":source"ed and for vimrc files, automatic <EOL> detection may be
done:
- When 'fileformats' is empty, there is no automatic detection. Dos
format will be used.
- When 'fileformats' is set to one or more names, automatic detection
is done. This is based on the first <NL> in the file: If there is a
<CR> in front of it, Dos format is used, otherwise Unix format is
used.
Also see |file-formats|.
For backwards compatibility: When this option is set to an empty
string or one format (no comma is included), 'textauto' is reset,
otherwise 'textauto' is set.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'filetype'* *'ft'*
'filetype' 'ft' string (default: "")
local to buffer
{not available when compiled without the |+autocmd|
feature}
When this option is set, the FileType autocommand event is triggered.
All autocommands that match with the value of this option will be
executed. Thus the value of 'filetype' is used in place of the file
name.
Otherwise this option does not always reflect the current file type.
This option is normally set when the file type is detected. To enable
this use the ":filetype on" command. |:filetype|
Setting this option to a different value is most useful in a modeline,
for a file for which the file type is not automatically recognized.
Example, for in an IDL file: >
/* vim: set filetype=idl : */
< |FileType| |filetypes|
Do not confuse this option with 'osfiletype', which is for the file
type that is actually stored with the file.
This option is not copied to another buffer, independent of the 's' or
'S' flag in 'cpoptions'.
*'fillchars'* *'fcs'*
'fillchars' 'fcs' string (default "vert:|,fold:-")
global
{not available when compiled without the |+windows|
and |+folding| features}
Characters to fill the statuslines and vertical separators.
It is a comma separated list of items:
item default Used for ~
stl:c ' ' or '^' statusline of the current window
stlnc:c ' ' or '-' statusline of the non-current windows
vert:c '|' vertical separators |:vsplit|
fold:c '-' filling 'foldtext'
diff:c '-' deleted lines of the 'diff' option
Any one that is omitted will fall back to the default. For "stl" and
"stlnc" the space will be used when there is highlighting, '^' or '-'
otherwise.
Example: >
:set fillchars=stl:^,stlnc:-,vert:\|,fold:-,diff:-
< This is similar to the default, except that these characters will also
be used when there is highlighting.
The highlighting used for these items:
item highlight group ~
stl:c StatusLine |hl-StatusLine|
stlnc:c StatusLineNC |hl-StatusLineNC|
vert:c VertSplit |hl-VertSplit|
fold:c Folded |hl-Folded|
diff:c DiffDelete |hl-DiffDelete|
*'fkmap'* *'fk'* *'nofkmap'* *'nofk'*
'fkmap' 'fk' boolean (default off) *E198*
global
{only available when compiled with the |+rightleft|
feature}
When on, the keyboard is mapped for the Farsi character set.
Normally you would set 'allowrevins' and use CTRL-_ in insert mode to
toggle this option |i_CTRL-_|. See |farsi.txt|.
*'foldclose'* *'fcl'*
'foldclose' 'fcl' string (default "")
global
{not available when compiled without the |+folding|
feature}
When set to "all", a fold is closed when the cursor isn't in it and
its level is higher than 'foldlevel'. Useful if you want folds to
automatically close when moving out of them.
*'foldcolumn'* *'fdc'*
'foldcolumn' 'fdc' number (default 0)
local to window
{not available when compiled without the |+folding|
feature}
When non-zero, a column with the specified width is shown at the side
of the window which indicates open and closed folds. The maximum
value is 12.
See |folding|.
*'foldenable'* *'fen'* *'nofoldenable'* *'nofen'*
'foldenable' 'fen' boolean (default on)
local to window
{not available when compiled without the |+folding|
feature}
When off, all folds are open. This option can be used to quickly
switch between showing all text unfolded and viewing the text with
folds (including manually opened or closed folds). It can be toggled
with the |zi| command. The 'foldcolumn' will remain blank when
'foldenable' is off.
This option is set by commands that create a new fold or close a fold.
See |folding|.
*'foldexpr'* *'fde'*
'foldexpr' 'fde' string (default: "0")
local to window
{not available when compiled without the |+folding|
or |+eval| feature}
The expression used for when 'foldmethod' is "expr". It is evaluated
for each line to obtain its fold level. See |fold-expr|. Also see
|eval-sandbox|.
*'foldignore'* *'fdi'*
'foldignore' 'fdi' string (default: "#")
local to window
{not available when compiled without the |+folding|
feature}
Used only when 'foldmethod' is "indent". Lines starting with
characters in 'foldignore' will get their fold level from surrounding
lines. White space is skipped before checking for this character.
The default "#" works well for C programs. See |fold-indent|.
*'foldlevel'* *'fdl'*
'foldlevel' 'fdl' number (default: 0)
local to window
{not available when compiled without the |+folding|
feature}
Sets the fold level: Folds with a higher level will be closed.
Setting this option to zero will close all folds. Higher numbers will
close fewer folds.
This option is set by commands like |zm|, |zM| and |zR|.
See |fold-foldlevel|.
*'foldlevelstart'* *'fdls'*
'foldlevelstart' 'fdls' number (default: -1)
global
{not available when compiled without the |+folding|
feature}
Sets 'foldlevel' when starting to edit another buffer in a window.
Useful to always start editing with all folds closed (value zero),
some folds closed (one) or no folds closed (99).
This is done before reading any modeline, thus a setting in a modeline
overrules this option. Starting to edit a file for |diff-mode| also
ignores this option and closes all folds.
It is also done before BufReadPre autocommands, to allow an autocmd to
overrule the 'foldlevel' value for specific files.
When the value is negative, it is not used.
*'foldmarker'* *'fmr'* *E536*
'foldmarker' 'fmr' string (default: "{{{,}}}")
local to window
{not available when compiled without the |+folding|
feature}
The start and end marker used when 'foldmethod' is "marker". There
must be one comma, which separates the start and end marker. The
marker is a literal string (a regular expression would be too slow).
See |fold-marker|.
*'foldmethod'* *'fdm'*
'foldmethod' 'fdm' string (default: "manual")
local to window
{not available when compiled without the |+folding|
feature}
The kind of folding used for the current window. Possible values:
|fold-manual| manual Folds are created manually.
|fold-indent| indent Lines with equal indent form a fold.
|fold-expr| expr 'foldexpr' gives the fold level of a line.
|fold-marker| marker Markers are used to specify folds.
|fold-syntax| syntax Syntax highlighting items specify folds.
|fold-diff| diff Fold text that is not changed.
*'foldminlines'* *'fml'*
'foldminlines' 'fml' number (default: 1)
local to window
{not available when compiled without the |+folding|
feature}
Sets the minimum number of screen lines for a fold to be displayed
closed. Also for manually closed folds.
Note that this only has an effect of what is displayed. After using
"zc" to close a fold, which is displayed open because it's smaller
than 'foldminlines', a following "zc" may close a containing fold.
*'foldnestmax'* *'fdn'*
'foldnestmax' 'fdn' number (default: 20)
local to window
{not available when compiled without the |+folding|
feature}
Sets the maximum nesting of folds for the "indent" and "syntax"
methods. This avoids that too many folds will be created. Using more
than 20 doesn't work, because the internal limit is 20.
*'foldopen'* *'fdo'*
'foldopen' 'fdo' string (default: "block,hor,mark,percent,quickfix,
search,tag,undo")
global
{not available when compiled without the |+folding|
feature}
Specifies for which type of commands folds will be opened, if the
command moves the cursor into a closed fold. It is a comma separated
list of items.
item commands ~
all any
block "(", "{", "[[", "[{", etc.
hor horizontal movements: "l", "w", "fx", etc.
insert any command in Insert mode
jump far jumps: "G", "gg", etc.
mark jumping to a mark: "'m", CTRL-O, etc.
percent "%"
quickfix ":cn", ":crew", ":make", etc.
search search for a pattern: "/", "n", "*", "gd", etc.
(not for a search pattern in a ":" command)
tag jumping to a tag: ":ta", CTRL-T, etc.
undo undo or redo: "u" and CTRL-R
When the command is part of a mapping this option is not used. Add
the |zv| command to the mapping to get the same effect.
When a movement command is used for an operator (e.g., "dl" or "y%")
this option is not used. This means the operator will include the
whole closed fold.
Note that vertical movements are not here, because it would make it
very difficult to move onto a closed fold.
In insert mode the folds containing the cursor will always be open
when text is inserted.
To close folds you can re-apply 'foldlevel' with the |zx| command or
set the 'foldclose' option to "all".
*'foldtext'* *'fdt'*
'foldtext' 'fdt' string (default: "foldtext()")
local to window
{not available when compiled without the |+folding|
feature}
An expression which is used to specify the text displayed for a closed
fold. See |fold-foldtext|.
*'formatoptions'* *'fo'*
'formatoptions' 'fo' string (Vim default: "tcq", Vi default: "vt")
local to buffer
This is a sequence of letters which describes how automatic
formatting is to be done. See |fo-table|. When the 'paste' option is
on, no formatting is done (like 'formatoptions' is empty). Commas can
be inserted for readability.
To avoid problems with flags that are added in the future, use the
"+=" and "-=" feature of ":set" |add-option-flags|.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'formatprg'* *'fp'*
'formatprg' 'fp' string (default "")
global
The name of an external program that will be used to format the lines
selected with the "gq" command. The program must take the input on
stdin and produce the output on stdout. The Unix program "fmt" is
such a program. If this option is an empty string, the internal
format function will be used |C-indenting|. Environment variables are
expanded |:set_env|. See |option-backslash| about including spaces
and backslashes.
This option cannot be set from a |modeline|, for security reasons.
-->
*'gdefault'* *'gd'* *'nogdefault'* *'nogd'*
'gdefault' 'gd' boolean (default off)
global
When on, the ":substitute" flag 'g' is default on. This means that
all matches in a line are substituted instead of one. When a 'g' flag
is given to a ":substitute" command, this will toggle the substitution
of all or one match. See |complex-change|.
command 'gdefault' on 'gdefault' off ~
:s/// subst. all subst. one
:s///g subst. one subst. all
:s///gg subst. all subst. one
<!--
*'grepformat'* *'gfm'*
'grepformat' 'gfm' string (default "%f:%l%m,%f %l%m")
global
Format to recognize for the ":grep" command output.
This is a scanf-like string that uses the same format as the
'errorformat' option: see |errorformat|.
*'grepprg'* *'gp'*
'grepprg' 'gp' string (default "grep -n ",
Unix: "grep -n $* /dev/null",
Win32: "findstr /n" or "grep -n",
VMS: "SEARCH/NUMBERS ")
global or local to buffer |global-local|
Program to use for the ":grep" command. This option may contain '%'
and '#' characters, which are expanded like when used in a command-
line. The placeholder "$*" is allowed to specify where the arguments
will be included. Environment variables are expanded |:set_env|. See
|option-backslash| about including spaces and backslashes.
When your "grep" accepts the "-H" argument, use this to make ":grep"
also work well with a single file: >
:set grepprg=grep\ -nH
< See also the section |:make_makeprg|, since most of the comments there
apply equally to 'grepprg'.
For Win32, the default is "findstr /n" if "findstr.exe" can be found,
otherwise it's "grep -n".
This option cannot be set from a |modeline|, for security reasons.
*'guicursor'* *'gcr'* *E545* *E546* *E548* *E549*
'guicursor' 'gcr' string (default "n-v-c:block-Cursor/lCursor,
ve:ver35-Cursor,
o:hor50-Cursor,
i-ci:ver25-Cursor/lCursor,
r-cr:hor20-Cursor/lCursor,
sm:block-Cursor
-blinkwait175-blinkoff150-blinkon175",
for MS-DOS and Win32 console:
"n-v-c:block,o:hor50,i-ci:hor15,
r-cr:hor30,sm:block")
global
{only available when compiled with GUI enabled, and
for MS-DOS and Win32 console}
This option tells Vim what the cursor should look like in different
modes. It fully works in the GUI. In an MSDOS or Win32 console, only
the height of the cursor can be changed. This can be done by
specifying a block cursor, or a percentage for a vertical or
horizontal cursor.
The option is a comma separated list of parts. Each part consist of a
mode-list and an argument-list:
mode-list:argument-list,mode-list:argument-list,..
The mode-list is a dash separated list of these modes:
n Normal mode
v Visual mode
ve Visual mode with 'selection' "exclusive" (same as 'v',
if not specified)
o Operator-pending mode
i Insert mode
r Replace mode
c Command-line Normal (append) mode
ci Command-line Insert mode
cr Command-line Replace mode
sm showmatch in Insert mode
a all modes
The argument-list is a dash separated list of these arguments:
hor{N} horizontal bar, {N} percent of the character height
ver{N} vertical bar, {N} percent of the character width
block block cursor, fills the whole character
[only one of the above three should be present]
blinkwait{N} *cursor-blinking*
blinkon{N}
blinkoff{N}
blink times for cursor: blinkwait is the delay before
the cursor starts blinking, blinkon is the time that
the cursor is shown and blinkoff is the time that the
cursor is not shown. The times are in msec. When one
of the numbers is zero, there is no blinking. The
default is: "blinkwait700-blinkon400-blinkoff250".
These numbers are used for a missing entry. This
means that blinking is enabled by default. To switch
blinking off you can use "blinkon0". The cursor only
blinks when Vim is waiting for input, not while
executing a command.
To make the cursor blink in an xterm, see
|xterm-blink|.
{group-name}
a highlight group name, that sets the color and font
for the cursor
{group-name}/{group-name}
Two highlight group names, the first is used when
no language mappings are used, the other when they
are. |language-mapping|
Examples of parts:
n-c-v:block-nCursor in Normal, Command-line and Visual mode, use a
block cursor with colors from the "nCursor"
highlight group
i-ci:ver30-iCursor-blinkwait300-blinkon200-blinkoff150
In Insert and Command-line Insert mode, use a
30% vertical bar cursor with colors from the
"iCursor" highlight group. Blink a bit
faster.
The 'a' mode is different. It will set the given argument-list for
all modes. It does not reset anything to defaults. This can be used
to do a common setting for all modes. For example, to switch off
blinking: "a:blinkon0"
Examples of cursor highlighting: >
:highlight Cursor gui=reverse guifg=NONE guibg=NONE
:highlight Cursor gui=NONE guifg=bg guibg=fg
<
*'guifont'* *'gfn'*
*E235* *E596* *E610* *E611*
'guifont' 'gfn' string (default "")
global
{only available when compiled with GUI enabled}
This is a list of fonts which will be used for the GUI version of Vim.
In its simplest form the value is just one font name. When
the font cannot be found you will get an error message. To try other
font names a list can be specified, font names separated with commas.
The first valid font is used.
When 'guifontset' is not empty, 'guifont' is not used.
Spaces after a comma are ignored. To include a comma in a font name
precede it with a backslash. Setting an option requires an extra
backslash before a space and a backslash. See also
|option-backslash|. For example: >
:set guifont=Screen15,\ 7x13,font\\,with\\,commas
< will make vim try to use the font "Screen15" first, and if it fails it
will try to use "7x13" and then "font,with,commas" instead.
For the GTK+ 2 GUI the font name looks like this: >
:set guifont=Andale\ Mono\ 11
< That's all. XLFDs are no longer accepted.
*E236*
Note that the fonts must be mono-spaced (all characters have the same
width).
To preview a font on X11, you might be able to use the "xfontsel"
program. The "xlsfonts" program gives a list of all available fonts.
For Win32, GTK and Photon only: >
:set guifont=*
< will bring up a font requester, where you can pick the font you want.
If none of the fonts can be loaded, vim will keep the current setting.
If an empty font list is given, vim will try using other resource
settings (for X, it will use the Vim.font resource), and finally it
will try some builtin default which should always be there ("7x13" in
the case of X). The font names given should be "normal" fonts. Vim
will try to find the related bold and italic fonts.
For the Win32 GUI *E244* *E245*
- takes these options in the font name:
hXX - height is XX (points, can be floating-point)
wXX - width is XX (points, can be floating-point)
b - bold
i - italic
u - underline
s - strikeout
cXX - character set XX. valid charsets are: ANSI, ARABIC,
BALTIC, CHINESEBIG5, DEFAULT, EASTEUROPE, GB2312, GREEK,
HANGEUL, HEBREW, JOHAB, MAC, OEM, RUSSIAN, SHIFTJIS,
SYMBOL, THAI, TURKISH, VIETNAMESE ANSI and BALTIC.
Use a ':' to separate the options.
- A '_' can be used in the place of a space, so you don't need to use
backslashes to escape the spaces.
- Examples: >
:set guifont=courier_new:h12:w5:b:cRUSSIAN
:set guifont=Andale_Mono:h7.5:w4.5
< Have a look at <http://nova.bsuvc.bsu.edu/prn/monofont/> for
mono-spaced fonts and comments on them.
See also |font-sizes|.
*'guifontset'* *'gfs'*
*E250* *E252* *E234* *E597* *E598*
'guifontset' 'gfs' string (default "")
global
{only available when compiled with GUI enabled and
with the |+xfontset| feature}
{not available in the GTK+ 2 GUI}
When not empty, specifies two (or more) fonts to be used. The first
one for normal English, the second one for your special language. See
|xfontset|.
Setting this option also means that all font names will be handled as
a fontset name. Also the ones used for the "font" argument of the
|:highlight| command.
The fonts must match with the current locale. If fonts for the
character sets that the current locale uses are not included, setting
'guifontset' will fail.
Note the difference between 'guifont' and 'guifontset': In 'guifont'
the comma-separated names are alternative names, one of which will be
used. In 'guifontset' the whole string is one fontset name,
including the commas. It is not possible to specify alternative
fontset names.
This example works on many X11 systems: >
:set guifontset=-*-*-medium-r-normal--16-*-*-*-c-*-*-*
<
*'guifontwide'* *'gfw'* *E231* *E533* *E534*
'guifontwide' 'gfw' string (default "")
global
{only available when compiled with GUI enabled}
When not empty, specifies a comma-separated list of fonts to be used
for double-width characters. The first font that can be loaded is
used.
Note: The size of these fonts must be exactly twice as wide as the one
specified with 'guifont' and the same height.
All GUI versions but GTK+ 2:
'guifontwide' is only used when 'encoding' is set to "utf-8" and
'guifontset' is empty or invalid.
When 'guifont' is set and a valid font is found in it and
'guifontwide' is empty Vim will attempt to find a matching
double-width font and set 'guifontwide' to it.
GTK+ 2 GUI only: *guifontwide_gtk2*
If set and valid, 'guifontwide' is always used for double width
characters, even if 'encoding' is not set to "utf-8".
Vim does not attempt to find an appropriate value for 'guifontwide'
automatically. If 'guifontwide' is empty Pango/Xft will choose the
font for characters not available in 'guifont'. Thus you do not need
to set 'guifontwide' at all unless you want to override the choice
made by Pango/Xft.
*'guiheadroom'* *'ghr'*
'guiheadroom' 'ghr' number (default 50)
global
The number of pixels subtracted from the screen height when fitting
the GUI window on the screen. Set this before the GUI is started,
e.g., in your |gvimrc| file. When zero, the whole screen height will
be used by the window. When positive, the specified number of pixel
lines will be left for window decorations and other items on the
screen. Set it to a negative value to allow windows taller than the
screen.
*'guioptions'* *'go'*
'guioptions' 'go' string (default "gmrLtT" (MS-Windows),
"agimrLtT" (GTK, Motif and Athena)
global
{only available when compiled with GUI enabled}
This option only has an effect in the GUI version of vim. It is a
sequence of letters which describes what components and options of the
GUI should be used.
To avoid problems with flags that are added in the future, use the
"+=" and "-=" feature of ":set" |add-option-flags|.
Valid letters are as follows:
*guioptions_a*
'a' Autoselect: If present, then whenever VISUAL mode is started,
or the Visual area extended, Vim tries to become the owner of
the windowing system's global selection. This means that the
Visually highlighted text is available for pasting into other
applications as well as into Vim itself. When the Visual mode
ends, possibly due to an operation on the text, or when an
application wants to paste the selection, the highlighted text
is automatically yanked into the "* selection register.
Thus the selection is still available for pasting into other
applications after the VISUAL mode has ended.
If not present, then Vim won't become the owner of the
windowing system's global selection unless explicitly told to
by a yank or delete operation for the "* register.
The same applies to the modeless selection.
'A' Autoselect for the modeless selection. Like 'a', but only
applies to the modeless selection.
'guioptions' autoselect Visual autoselect modeless ~
"" - -
"a" yes yes
"A" - yes
"aA" yes yes
'c' Use console dialogs instead of popup dialogs for simple
choices.
'f' Foreground: Don't use fork() to detach the GUI from the shell
where it was started. Use this for programs that wait for the
editor to finish (e.g., an e-mail program). Alternatively you
can use "gvim -f" or ":gui -f" to start the GUI in the
foreground. |gui-fork|
Note: Set this option in the vimrc file. The forking may have
happened already when the gvimrc file is read.
'i' Use a Vim icon. For GTK with KDE it is used in the left-upper
corner of the window. It's black&white on non-GTK, because of
limitations of X11. For a color icon, see |X11-icon|.
'm' Menu bar is present.
'M' The system menu "$VIMRUNTIME/menu.vim" is not sourced. Note
that this flag must be added in the .vimrc file, before
switching on syntax or filetype recognition (when the .gvimrc
file is sourced the system menu has already been loaded; the
":syntax on" and ":filetype on" commands load the menu too).
'g' Grey menu items: Make menu items that are not active grey. If
'g' is not included inactive menu items are not shown at all.
Exception: Athena will always use grey menu items.
't' Include tearoff menu items. Currently only works for Win32,
GTK+, and Motif 1.2 GUI.
'T' Include Toolbar. Currently only in Win32, GTK+, Motif, and
Athena GUIs.
'r' Right-hand scrollbar is always present.
'R' Right-hand scrollbar is present when there is a vertically
split window.
'l' Left-hand scrollbar is always present.
'L' Left-hand scrollbar is present when there is a vertically
split window.
'b' Bottom (horizontal) scrollbar is present.
And yes, you may even have scrollbars on the left AND the right if
you really want to :-). See |gui-scrollbars| for more information.
'v' Use a vertical button layout for dialogs. When not included,
a horizontal layout is preferred, but when it doesn't fit a
vertical layout is used anyway.
'p' Use Pointer callbacks for X11 GUI. This is required for some
window managers. If the cursor is not blinking or hollow at
the right moment, try adding this flag. This must be done
before starting the GUI. Set it in your gvimrc. Adding or
removing it after the GUI has started has no effect.
'F' Add a footer. Only for Motif. See |gui-footer|.
*'guipty'* *'noguipty'*
'guipty' boolean (default on)
global
{only available when compiled with GUI enabled}
Only in the GUI: If on, an attempt is made to open a pseudo-tty for
I/O to/from shell commands. See |gui-pty|.
*'helpfile'* *'hf'*
'helpfile' 'hf' string (default (MSDOS) "$VIMRUNTIME\doc\help.txt"
(others) "$VIMRUNTIME/doc/help.txt")
global
Name of the main help file. All distributed help files should be
placed together in one directory. Additionally, all "doc" directories
in 'runtimepath' will be used.
Environment variables are expanded |:set_env|. For example:
"$VIMRUNTIME/doc/help.txt". If $VIMRUNTIME is not set, $VIM is also
tried. Also see |$VIMRUNTIME| and |option-backslash| about including
spaces and backslashes.
This option cannot be set from a |modeline|, for security reasons.
*'helpheight'* *'hh'*
'helpheight' 'hh' number (default 20)
global
{not available when compiled without the +windows
feature}
Minimal initial height of the help window when it is opened with the
":help" command. The initial height of the help window is half of the
current window, or (when the 'ea' option is on) the same as other
windows. When the height is less than 'helpheight', the height is
set to 'helpheight'. Set to zero to disable.
*'hidden'* *'hid'* *'nohidden'* *'nohid'*
'hidden' 'hid' boolean (default off)
global
When off a buffer is unloaded when it is |abandon|ed. When on a
buffer becomes hidden when it is |abandon|ed. If the buffer is still
displayed in another window, it does not become hidden, of course.
The commands that move through the buffer list sometimes make a buffer
hidden although the 'hidden' option is off: When the buffer is
modified, 'autowrite' is off or writing is not possible, and the '!'
flag was used. See also |windows.txt|.
This option is set for one command with ":hide {command}" |:hide|.
WARNING: It's easy to forget that you have changes in hidden buffers.
Think twice when using ":q!" or ":qa!".
*'highlight'* *'hl'*
'highlight' 'hl' string (default (as a single string):
"8:SpecialKey,@:NonText,d:Directory,
e:ErrorMsg,i:IncSearch,l:Search,m:MoreMsg,
M:ModeMsg,n:LineNr,r:Question,
s:StatusLine,S:StatusLineNC,c:VertSplit
t:Title,v:Visual,w:WarningMsg,W:WildMenu,
f:Folded,F:FoldColumn")
global
This option can be used to set highlighting mode for various
occasions. It is a comma separated list of character pairs. The
first character in a pair gives the occasion, the second the mode to
use for that occasion. The occasions are:
|hl-SpecialKey| 8 Meta and special keys listed with ":map"
|hl-NonText| @ '~' and '@' at the end of the window and
characters from 'showbreak'
|hl-Directory| d directories in CTRL-D listing and other special
things in listings
|hl-ErrorMsg| e error messages
h (obsolete, ignored)
|hl-IncSearch| i 'incsearch' highlighting
|hl-Search| l last search pattern highlighting (see 'hlsearch')
|hl-MoreMsg| m |more-prompt|
|hl-ModeMsg| M Mode (e.g., "-- INSERT --")
|hl-LineNr| n line number for ":number" and ":#" commands
|hl-Question| r |hit-enter| prompt and yes/no questions
|hl-StatusLine| s status line of current window |status-line|
|hl-StatusLineNC| S status lines of not-current windows
|hl-Title| t Titles for output from ":set all", ":autocmd" etc.
|hl-VertSplit| c column used to separate vertically split windows
|hl-Visual| v Visual mode
|hl-VisualNOS| V Visual mode when Vim does is "Not Owning the
Selection" Only X11 Gui's |gui-x11| and
|xterm-clipboard|.
|hl-WarningMsg| w warning messages
|hl-WildMenu| W wildcard matches displayed for 'wildmenu'
|hl-Folded| f line used for closed folds
|hl-FoldColumn| F 'foldcolumn'
The display modes are:
r reverse (termcap entry "mr" and "me")
i italic (termcap entry "ZH" and "ZR")
b bold (termcap entry "md" and "me")
s standout (termcap entry "so" and "se")
u underline (termcap entry "us" and "ue")
n no highlighting
- no highlighting
: use a highlight group
The default is used for occasions that are not included.
If you want to change what the display modes do, see |dos-colors|
for an example.
When using the ':' display mode, this must be followed by the name of
a highlight group. A highlight group can be used to define any type
of highlighting, including using color. See |:highlight| on how to
define one. The default uses a different group for each occasion.
See |highlight-default| for the default highlight groups.
-->
*'hlsearch'* *'hls'* *'nohlsearch'* *'nohls'*
'hlsearch' 'hls' boolean (default off)
global
When there is a previous search pattern, highlight all its matches.
<!--
The type of highlighting used can be set with the 'l' occasion in the
'highlight' option. This uses the "Search" highlight group by
default.
-->
Note that only the matching text is highlighted, any offsets
are not applied.
<!--
See also: 'incsearch' and |:match|.
-->
When you get bored looking at the highlighted matches, you can turn it
off with |:nohlsearch|. As soon as you use a search command, the
highlighting comes back.
When the search pattern can match an end-of-line, Vim will try to
highlight all of the matched text. However, this depends on where the
search starts. This will be the first line in the window or the first
line below a closed fold. A match in a previous line which is not
drawn may not continue in an newly drawn line.
*'history'* *'hi'*
'history' 'hi' number (default: 20)
global
A history of ":" commands, and a history of previous search patterns
are remembered. This option decides how many entries may be stored in
each of these histories (see |cmdline-editing|).
<!--
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
-->
<!--
*'hkmap'* *'hk'* *'nohkmap'* *'nohk'*
'hkmap' 'hk' boolean (default off)
global
{only available when compiled with the |+rightleft|
feature}
When on, the keyboard is mapped for the Hebrew character set.
Normally you would set 'allowrevins' and use CTRL-_ in insert mode to
toggle this option. See |rileft.txt|.
NOTE: This option is reset when 'compatible' is set.
*'hkmapp'* *'hkp'* *'nohkmapp'* *'nohkp'*
'hkmapp' 'hkp' boolean (default off)
global
{only available when compiled with the |+rightleft|
feature}
When on, phonetic keyboard mapping is used. 'hkmap' must also be on.
This is useful if you have a non-Hebrew keyboard.
See |rileft.txt|.
NOTE: This option is reset when 'compatible' is set.
*'icon'* *'noicon'*
'icon' boolean (default off, on when title can be restored)
global
{not available when compiled without the |+title|
feature}
When on, the icon text of the window will be set to the value of
'iconstring' (if it is not empty), or to the name of the file
currently being edited. Only the last part of the name is used.
Overridden by the 'iconstring' option.
Only works if the terminal supports setting window icons (currently
only X11 GUI and terminals with a non-empty 't_IS' option - these are
Unix xterm and iris-ansi by default, where 't_IS' is taken from the
builtin termcap).
When Vim was compiled with HAVE_X11 defined, the original icon will be
restored if possible |X11|. See |X11-icon| for changing the icon on
X11.
*'iconstring'*
'iconstring' string (default "")
global
{not available when compiled without the |+title|
feature}
When this option is not empty, it will be used for the icon text of
the window. This happens only when the 'icon' option is on.
Only works if the terminal supports setting window icon text
(currently only X11 GUI and terminals with a non-empty 't_IS' option).
Does not work for MS Windows.
When Vim was compiled with HAVE_X11 defined, the original icon will be
restored if possible |X11|.
When this option contains printf-style '%' items, they will be
expanded according to the rules used for 'statusline'. See
'titlestring' for example settings.
{not available when compiled without the |+statusline| feature}
-->
*'ignorecase'* *'ic'* *'noignorecase'* *'noic'*
'ignorecase' 'ic' boolean (default off)
global
Ignore case in search patterns. Also used when searching in the tags
file.
Also see 'smartcase'.
Can be overruled by using "\c" or "\C" in the pattern, see
|/ignorecase|.
<!--
*'imactivatekey'* *'imak'*
'imactivatekey' 'imak' string (default "")
global
{only available when compiled with |+xim| and
|+GUI_GTK|}
Specifies the key that your Input Method in X-Windows uses for
activation. When this is specified correctly, vim can fully control
IM with 'imcmdline', 'iminsert' and 'imsearch'.
You can't use this option to change the activation key, the option
tells Vim what the key is.
Format:
[MODIFIER_FLAG-]KEY_STRING
These characters can be used for MODIFIER_FLAG (case is ignored):
S Shift key
L Lock key
C Control key
1 Mod1 key
2 Mod2 key
3 Mod3 key
4 Mod4 key
5 Mod5 key
Combinations are allowed, for example "S-C-space" or "SC-space" are
both shift+ctrl+space.
See <X11/keysymdef.h> and XStringToKeysym for KEY_STRING.
Example: >
:set imactivatekey=S-space
< "S-space" means shift+space. This is the activation key for kinput2 +
canna (Japanese), and ami (Korean).
*'imcmdline'* *'imc'* *'noimcmdline'* *'noimc'*
'imcmdline' 'imc' boolean (default off)
global
{only available when compiled with the |+xim|
|+multi_byte_ime| or |global-ime| feature}
When set the Input Method is always on when starting to edit a command
line, unless entering a search pattern (see 'imsearch' for that).
Setting this option is useful when your input method allows entering
English characters directly, e.g., when it's used to type accented
characters with dead keys.
*'imdisable'* *'imd'* *'nodisable'* *'noimd'*
'imdisable' 'imd' boolean (default off, on for some systems (SGI))
global
{only available when compiled with the |+xim|
|+multi_byte_ime| or |global-ime| feature}
When set the Input Method is never used. This is useful to disable
the IM when it doesn't work properly.
Currently this option is on by default for SGI/IRIX machines. This
may change in later releases.
*'iminsert'* *'imi'*
'iminsert' 'imi' number (default 0, 2 when an input method is supported)
local to buffer
Specifies whether :lmap or an Input Method (IM) is to be used in
Insert mode. Valid values:
0 :lmap is off and IM is off
1 :lmap is ON and IM is off
2 :lmap is off and IM is ON
2 is available only when compiled with the |+multi_byte_ime|, |+xim|
or |global-ime|.
To always reset the option to zero when leaving Insert mode with <Esc>
this can be used: >
:inoremap <ESC> <ESC>:set iminsert=0<CR>
< This makes :lmap and IM turn off automatically when leaving Insert
mode.
Note that this option changes when using CTRL-^ in Insert mode
|i_CTRL-^|.
The value is set to 1 when setting 'keymap' to a valid keymap name.
It is also used for the argument of commands like "r" and "f".
The value 0 may not work correctly with Athena and Motif with some XIM
methods. Use 'imdisable' to disable XIM then.
*'imsearch'* *'ims'*
'imsearch' 'ims' number (default 0, 2 when an input method is supported)
local to buffer
Specifies whether :lmap or an Input Method (IM) is to be used when
entering a search pattern. Valid values:
-1 the value of 'iminsert' is used, makes it look like
'iminsert' is also used when typing a search pattern
0 :lmap is off and IM is off
1 :lmap is ON and IM is off
2 :lmap is off and IM is ON
Note that this option changes when using CTRL-^ in Insert mode
|c_CTRL-^|.
The value is set to 1 when it is not -1 and setting the 'keymap'
option to a valid keymap name.
The value 0 may not work correctly with Athena and Motif with some XIM
methods. Use 'imdisable' to disable XIM then.
*'include'* *'inc'*
'include' 'inc' string (default "^#\s*include")
global or local to buffer |global-local|
{not available when compiled without the
|+find_in_path| feature}
Pattern to be used to find an include command. It is a search
pattern, just like for the "/" command (See |pattern|). The default
value is for C programs. This option is used for the commands "[i",
"]I", "[d", etc.. The 'isfname' option is used to recognize the file
name that comes after the matched pattern. See |option-backslash|
about including spaces and backslashes.
*'includeexpr'* *'inex'*
'includeexpr' 'inex' string (default "")
local to buffer
{not available when compiled without the
|+find_in_path| or |+eval| feature}
Expression to be used to transform the string found with the 'include'
option to a file name. Mostly useful to change "." to "/" for Java: >
:set includeexpr=substitute(v:fname,'\\.','/','g')
< The "v:fname" variable will be set to the file name that was detected.
Evaluated in the |sandbox|.
Also used for the |gf| command if an unmodified file name can't be
found. Allows doing "gf" on the name after an 'include' statement.
Also used for |<cfile>|.
*'incsearch'* *'is'* *'noincsearch'* *'nois'*
'incsearch' 'is' boolean (default off)
global
{not available when compiled without the
|+extra_search| feature}
While typing a search pattern, show immediately where the so far
typed pattern matches. The matched string is highlighted. If the
pattern is invalid or not found, nothing is shown. The screen will
be updated often, this is only useful on fast terminals. Note that
the match will be shown, but the cursor is not actually positioned
there. You still need to finish the search command with <CR> to move
the cursor. The highlighting can be set with the 'i' flag in
'highlight'. See also: 'hlsearch'.
NOTE: This option is reset when 'compatible' is set.
*'indentexpr'* *'inde'*
'indentexpr' 'inde' string (default "")
local to buffer
{not available when compiled without the |+cindent|
or |+eval| features}
Expression which is evaluated to obtain the proper indent for a line.
It is used when a new line is created, for the |=| operator and
in Insert mode as specified with the 'indentkeys' option.
When this option is not empty, it overrules the 'cindent' and
'smartindent' indenting.
When 'paste' is set this option is not used for indenting.
The expression is evaluated with |v:lnum| set to the line number for
which the indent is to be computed.
The expression must return the number of spaces worth of indent. It
can return "-1" to keep the current indent (this means 'autoindent' is
used for the indent).
Functions useful for computing the indent are |indent()|, |cindent()|
and |lispindent()|.
The evaluation of the expression must not have side effects! It must
not change the text, jump to another window, etc. Afterwards the
cursor position is always restored, thus the cursor may be moved.
Normally this option would be set to call a function: >
:set indentexpr=GetMyIndent()
< Error messages will be suppressed, unless the 'debug' option contains
"msg".
See |indent-expression|. Also see |eval-sandbox|.
NOTE: This option is made empty when 'compatible' is set.
*'indentkeys'* *'indk'*
'indentkeys' 'indk' string (default "0{,0},:,0#,!^F,o,O,e")
local to buffer
{not available when compiled without the |+cindent|
feature}
A list of keys that, when typed in Insert mode, cause reindenting of
the current line. Only happens if 'indentexpr' isn't empty.
The format is identical to 'cinkeys', see |indentkeys-format|.
See |C-indenting| and |indent-expression|.
*'infercase'* *'inf'* *'noinfercase'* *'noinf'*
'infercase' 'inf' boolean (default off)
local to buffer
When doing keyword completion in insert mode |ins-completion|, and
'ignorecase' is also on, the case of the match is adjusted. If the
typed text contains a lowercase letter where the match has an upper
case letter, the completed part is made lowercase. If the typed text
has no lowercase letters and the match has a lowercase letter where
the typed text has an uppercase letter, and there is a letter before
it, the completed part is made uppercase.
*'insertmode'* *'im'* *'noinsertmode'* *'noim'*
'insertmode' 'im' boolean (default off)
global
Makes Vim work in a way that Insert mode is the default mode. Useful
if you want to use Vim as a modeless editor. Used for |evim|.
These Insert mode commands will be useful:
- Use the cursor keys to move around.
- Use CTRL-O to execute one Normal mode command |i_CTRL-O|). When
this is a mapping, it is executed as if 'insertmode' was off.
Normal mode remains active until the mapping is finished.
*i_CTRL-L*
- Use CTRL-L to execute a number of Normal mode commands, then use
<Esc> to get back to Insert mode.
These items change when 'insertmode' is set:
- when starting to edit of a file, Vim goes to Insert mode.
- <Esc> in Insert mode is a no-op and beeps.
- <Esc> in Normal mode makes Vim go to Insert mode.
- CTRL-L in Insert mode is a command, it is not inserted.
- CTRL-Z in Insert mode suspends Vim, see |CTRL-Z|. *i_CTRL-Z*
However, when <Esc> is used inside a mapping, it behaves like
'insertmode' was not set. This was done to be able to use the same
mappings with 'insertmode' set or not set.
When executing commands with |:normal| 'insertmode' is not used.
NOTE: This option is reset when 'compatible' is set.
*'isfname'* *'isf'*
'isfname' 'isf' string (default for MS-DOS, Win32 and OS/2:
"@,48-57,/,\,.,-,_,+,,,#,$,%,{,},[,],:,@-@,!,~,="
for AMIGA: "@,48-57,/,.,-,_,+,,,$,:"
for VMS: "@,48-57,/,.,-,_,+,,,#,$,%,<,>,[,],:,;,~"
for OS/390: "@,240-249,/,.,-,_,+,,,#,$,%,~,="
otherwise: "@,48-57,/,.,-,_,+,,,#,$,%,~,=")
global
The characters specified by this option are included in file names and
path names. Filenames are used for commands like "gf", "[i" and in
the tags file. It is also used for "\f" in a |pattern|.
Multi-byte characters 256 and above are always included, only the
characters up to 255 are specified with this option.
For UTF-8 the characters 0xa0 to 0xff are included as well.
Note that on systems using a backslash as path separator, Vim tries to
do its best to make it work as you would expect. That is a bit
tricky, since Vi originally used the backslash to escape special
characters. Vim will not remove a backslash in front of a normal file
name character on these systems, but it will on Unix and alikes. The
'&' and '^' are not included by default, because these are special for
cmd.exe.
The format of this option is a list of parts, separated with commas.
Each part can be a single character number or a range. A range is two
character numbers with '-' in between. A character number can be a
decimal number between 0 and 255 or the ASCII character itself (does
not work for digits). Example:
"_,-,128-140,#-43" (include '_' and '-' and the range
128 to 140 and '#' to 43)
If a part starts with '^', the following character number or range
will be excluded from the option. The option is interpreted from left
to right. Put the excluded character after the range where it is
included. To include '^' itself use it as the last character of the
option or the end of a range. Example:
"^a-z,#,^" (exclude 'a' to 'z', include '#' and '^')
If the character is '@', all characters where isalpha() returns TRUE
are included. Normally these are the characters a to z and A to Z,
plus accented characters. To include '@' itself use "@-@". Examples:
"@,^a-z" All alphabetic characters, excluding lower
case letters.
"a-z,A-Z,@-@" All letters plus the '@' character.
A comma can be included by using it where a character number is
expected. Example:
"48-57,,,_" Digits, comma and underscore.
A comma can be excluded by prepending a '^'. Example:
" -~,^,,9" All characters from space to '~', excluding
comma, plus <Tab>.
See |option-backslash| about including spaces and backslashes.
*'isident'* *'isi'*
'isident' 'isi' string (default for MS-DOS, Win32 and OS/2:
"@,48-57,_,128-167,224-235"
otherwise: "@,48-57,_,192-255")
global
The characters given by this option are included in identifiers.
Identifiers are used in recognizing environment variables and after a
match of the 'define' option. It is also used for "\i" in a
|pattern|. See 'isfname' for a description of the format of this
option.
Careful: If you change this option, it might break expanding
environment variables. E.g., when '/' is included and Vim tries to
expand "$HOME/.viminfo". Maybe you should change 'iskeyword' instead.
*'iskeyword'* *'isk'*
'iskeyword' 'isk' string (Vim default for MS-DOS and Win32:
"@,48-57,_,128-167,224-235"
otherwise: "@,48-57,_,192-255"
Vi default: "@,48-57,_")
local to buffer
Keywords are used in searching and recognizing with many commands:
"w", "*", "[i", etc. It is also used for "\k" in a |pattern|. See
'isfname' for a description of the format of this option. For C
programs you could use "a-z,A-Z,48-57,_,.,-,>".
For a help file it is set to all non-blank printable characters except
'*', '"' and '|' (so that CTRL-] on a command finds the help for that
command).
When the 'lisp' option is on the '-' character is always included.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'isprint'* *'isp'*
'isprint' 'isp' string (default for MS-DOS, Win32, OS/2 and Macintosh:
"@,~-255"; otherwise: "@,161-255")
global
The characters given by this option are displayed directly on the
screen. It is also used for "\p" in a |pattern|. The characters from
space (ascii 32) to '~' (ascii 126) are always displayed directly,
even when they are not included in 'isprint' or excluded. See
'isfname' for a description of the format of this option.
Non-printable characters are displayed with two characters:
0 - 31 "^@" - "^_"
32 - 126 always single characters
127 "^?"
128 - 159 "~@" - "~_"
160 - 254 "| " - "|~"
255 "~?"
When 'encoding' is a Unicode one, illegal bytes from 128 to 255 are
displayed as <xx>, with the hexadecimal value of the byte.
When 'display' contains "uhex" all unprintable characters are
displayed as <xx>.
The NonText highlighting will be used for unprintable characters.
|hl-NonText|
Multi-byte characters 256 and above are always included, only the
characters up to 255 are specified with this option. When a character
is printable but it is not available in the current font, a
replacement character will be shown.
Unprintable and zero-width Unicode characters are displayed as <xxxx>.
There is no option to specify these characters.
*'joinspaces'* *'js'* *'nojoinspaces'* *'nojs'*
'joinspaces' 'js' boolean (default on)
global
Insert two spaces after a '.', '?' and '!' with a join command.
When 'cpoptions' includes the 'j' flag, only do this after a '.'.
Otherwise only one space is inserted.
NOTE: This option is set when 'compatible' is set.
*'key'*
'key' string (default "")
local to buffer
The key that is used for encrypting and decrypting the current buffer.
See |encryption|.
Careful: Do not set the key value by hand, someone might see the typed
key. Use the |:X| command. But you can make 'key' empty: >
:set key=
< It is not possible to get the value of this option with ":set key" or
"echo &key". This is to avoid showing it to someone who shouldn't
know. It also means you cannot see it yourself once you have set it,
be careful not to make a typing error!
*'keymap'* *'kmp'* *E544*
'keymap' 'kmp' string (default "")
local to buffer
{only available when compiled with the |+keymap|
feature}
Name of a keyboard mapping. See |mbyte-keymap|.
Setting this option to a valid keymap name has the side effect of
setting 'iminsert' to one, so that the keymap becomes effective.
'imsearch' is also set to one, unless it was -1
*'keymodel'* *'km'*
'keymodel' 'km' string (default "")
global
List of comma separated words, which enable special things that keys
can do. These values can be used:
startsel Using a shifted special key starts selection (either
Select mode or Visual mode, depending on "key" being
present in 'selectmode').
stopsel Using a not-shifted special key stops selection.
Special keys in this context are the cursor keys, <End>, <Home>,
<PageUp> and <PageDown>.
The 'keymodel' option is set by the |:behave| command.
*'keywordprg'* *'kp'*
'keywordprg' 'kp' string (default "man" or "man -s", DOS: ":help",
OS/2: "view /", VMS: "help")
global or local to buffer |global-local|
Program to use for the |K| command. Environment variables are
expanded |:set_env|. ":help" may be used to access the Vim internal
help. (Note that previously setting the global option to the empty
value did this, which is now deprecated.)
When "man" is used, Vim will automatically translate a count for the
"K" command to a section number. Also for "man -s", in which case the
"-s" is removed when there is no count.
See |option-backslash| about including spaces and backslashes.
Example: >
:set keywordprg=man\ -s
< This option cannot be set from a |modeline|, for security reasons.
*'langmap'* *'lmap'* *E357* *E358*
'langmap' 'lmap' string (default "")
global
{only available when compiled with the |+langmap|
feature}
This option allows switching your keyboard into a special language
mode. When you are typing text in Insert mode the characters are
inserted directly. When in command mode the 'langmap' option takes
care of translating these special characters to the original meaning
of the key. This means you don't have to change the keyboard mode to
be able to execute Normal mode commands.
This is the opposite of the 'keymap' option, where characters are
mapped in Insert mode.
This only works for 8-bit characters. The value of 'langmap' may be
specified with multi-byte characters (e.g., UTF-8), but only the lower
8 bits of each character will be used.
Example (for Greek): *greek* >
:set langmap=<3D>A,<2C>B,<2C>C,<2C>D,<2C>E,<2C>F,<2C>G,<2C>H,<2C>I,<2C>J,<2C>K,<2C>L,<2C>M,<2C>N,<2C>O,<2C>P,QQ,<2C>R,<2C>S,<2C>T,<2C>U,<2C>V,WW,<2C>X,<2C>Y,<2C>Z,<2C>a,<2C>b,<2C>c,<2C>d,<2C>e,<2C>f,<2C>g,<2C>h,<2C>i,<2C>j,<2C>k,<2C>l,<2C>m,<2C>n,<2C>o,<2C>p,qq,<2C>r,<2C>s,<2C>t,<2C>u,<2C>v,<2C>w,<2C>x,<2C>y,<2C>z
< Example (exchanges meaning of z and y for commands): >
:set langmap=zy,yz,ZY,YZ
<
The 'langmap' option is a list of parts, separated with commas. Each
part can be in one of two forms:
1. A list of pairs. Each pair is a "from" character immediately
followed by the "to" character. Examples: "aA", "aAbBcC".
2. A list of "from" characters, a semi-colon and a list of "to"
characters. Example: "abc;ABC"
Example: "aA,fgh;FGH,cCdDeE"
Special characters need to be preceded with a backslash. These are
";", ',' and backslash itself.
This will allow you to activate vim actions without having to switch
back and forth between the languages. Your language characters will
be understood as normal vim English characters (according to the
langmap mappings) in the following cases:
o Normal/Visual mode (commands, buffer/register names, user mappings)
o Insert/Replace Mode: Register names after CTRL-R
o Insert/Replace Mode: Mappings
Characters entered in Command-line mode will NOT be affected by
this option. Note that this option can be changed at any time
allowing to switch between mappings for different languages/encodings.
Use a mapping to avoid having to type it each time!
*'langmenu'* *'lm'*
'langmenu' 'lm' string (default "")
global
{only available when compiled with the |+menu| and
|+multi_lang| features}
Language to use for menu translation. Tells which file is loaded
from the "lang" directory in 'runtimepath': >
"lang/menu_" . &langmenu . ".vim"
< (without the spaces). For example, to always use the Dutch menus, no
matter what $LANG is set to: >
:set langmenu=nl_NL.ISO_8859-1
< When 'langmenu' is empty, |v:lang| is used.
If your $LANG is set to a non-English language but you do want to use
the English menus: >
:set langmenu=none
< This option must be set before loading menus, switching on filetype
detection or syntax highlighting. Once the menus are defined setting
this option has no effect. But you could do this: >
:source $VIMRUNTIME/delmenu.vim
:set langmenu=de_DE.ISO_8859-1
:source $VIMRUNTIME/menu.vim
< Warning: This deletes all menus that you defined yourself!
*'laststatus'* *'ls'*
'laststatus' 'ls' number (default 1)
global
The value of this option influences when the last window will have a
status line:
0: never
1: only if there are at least two windows
2: always
The screen looks nicer with a status line if you have several
windows, but it takes another screen line. |status-line|
*'lazyredraw'* *'lz'* *'nolazyredraw'* *'nolz'*
'lazyredraw' 'lz' boolean (default off)
global
When this option is set, the screen will not be redrawn while
executing macros, registers and other commands that have not been
typed. To force an update use |:redraw|.
*'linebreak'* *'lbr'* *'nolinebreak'* *'nolbr'*
'linebreak' 'lbr' boolean (default off)
local to window
{not available when compiled without the |+linebreak|
feature}
If on Vim will wrap long lines at a character in 'breakat' rather
than at the last character that fits on the screen. Unlike
'wrapmargin' and 'textwidth', this does not insert <EOL>s in the file,
it only affects the way the file is displayed, not its contents. The
value of 'showbreak' is used to put in front of wrapped lines. This
option is not used when the 'wrap' option is off or 'list' is on.
Note that <Tab> characters after an <EOL> are mostly not displayed
with the right amount of white space.
*'lines'* *E593*
'lines' number (default 24 or terminal height)
global
Number of lines in the display. Normally you don't need to set this.
That is done automatically by the terminal initialization code.
When Vim is running in the GUI or in a resizable window, setting this
option will cause the window size to be changed. When you only want
to use the size for the GUI, put the command in your |gvimrc| file.
When you set this option and Vim is unable to change the physical
number of lines of the display, the display may be messed up.
*'linespace'* *'lsp'*
'linespace' 'lsp' number (default 0, 1 for Win32 GUI)
global
{only in the GUI}
Number of pixel lines inserted between characters. Useful if the font
uses the full character cell height, making lines touch each other.
When non-zero there is room for underlining.
*'lisp'* *'nolisp'*
'lisp' boolean (default off)
local to buffer
{not available when compiled without the |+lispindent|
feature}
Lisp mode: When <Enter> is typed in insert mode set the indent for
the next line to Lisp standards (well, sort of). Also happens with
"cc" or "S". 'autoindent' must also be on for this to work. The 'p'
flag in 'cpoptions' changes the method of indenting: Vi compatible or
better. Also see 'lispwords'.
The '-' character is included in keyword characters. Redefines the
"=" operator to use this same indentation algorithm rather than
calling an external program if 'equalprg' is empty.
This option is not used when 'paste' is set.
{Vi: Does it a little bit differently}
*'lispwords'* *'lw'*
'lispwords' 'lw' string (default is very long)
global
{not available when compiled without the |+lispindent|
feature}
Comma separated list of words that influence the Lisp indenting.
|'lisp'|
*'list'* *'nolist'*
'list' boolean (default off)
local to window
List mode: Show tabs as CTRL-I, show end of line with $. Useful to
see the difference between tabs and spaces and for trailing blanks.
Note that this will also affect formatting (set with 'textwidth' or
'wrapmargin') when 'cpoptions' includes 'L'. See 'listchars' for
changing the way tabs are displayed.
*'listchars'* *'lcs'*
'listchars' 'lcs' string (default "eol:$")
global
Strings to use in 'list' mode. It is a comma separated list of string
settings.
eol:c Character to show at the end of each line. When
omitted, there is no extra character at the end of the
line.
tab:xy Two characters to be used to show a Tab. The first
char is used once. The second char is repeated to
fill the space that the Tab normally occupies.
"tab:>-" will show a Tab that takes four spaces as
">---". When omitted, a Tab is show as ^I.
trail:c Character to show for trailing spaces. When omitted,
trailing spaces are blank.
extends:c Character to show in the last column, when 'wrap' is
off and the line continues beyond the right of the
screen.
precedes:c Character to show in the first column, when 'wrap'
is off and there is text preceeding the character
visible in the first column.
The characters ':' and ',' should not be used. UTF-8 characters can
be used when 'encoding' is "utf-8", otherwise only printable
characters are allowed.
Examples: >
:set lcs=tab:>-,trail:-
:set lcs=tab:>-,eol:<
:set lcs=extends:>,precedes:<
< The "NonText" highlighting will be used for "eol", "extends" and
"precedes". "SpecialKey" for "tab" and "trail".
*'lpl'* *'nolpl'* *'loadplugins'* *'noloadplugins'*
'loadplugins' 'lpl' boolean (default on)
global
When on the plugin scripts are loaded when starting up |load-plugins|.
This option can be reset in your |vimrc| file to disable the loading
of plugins.
Note that using the "-u NONE" and "--noplugin" command line arguments
reset this option. |-u| |--noplugin|
*'magic'* *'nomagic'*
'magic' boolean (default on)
global
Changes the special characters that can be used in search patterns.
See |pattern|.
NOTE: To avoid portability problems with using patterns, always keep
this option at the default "on". Only switch it off when working with
old Vi scripts. In any other situation write patterns that work when
'magic' is on.
*'makeef'* *'mef'*
'makeef' 'mef' string (default: "")
global
{not available when compiled without the |+quickfix|
feature}
Name of the errorfile for the |:make| command (see |:make_makeprg|)
and the |:grep| command.
When it is empty, an internally generated temp file will be used.
When "##" is included, it is replaced by a number to make the name
unique. This makes sure that the ":make" command doesn't overwrite an
existing file.
NOT used for the ":cf" command. See 'errorfile' for that.
Environment variables are expanded |:set_env|.
See |option-backslash| about including spaces and backslashes.
This option cannot be set from a |modeline|, for security reasons.
*'makeprg'* *'mp'*
'makeprg' 'mp' string (default "make", VMS: "MMS")
global or local to buffer |global-local|
Program to use for the ":make" command. See |:make_makeprg|. This
option may contain '%' and '#' characters, which are expanded like
when used in a command-line. Environment variables are expanded
|:set_env|. See |option-backslash| about including spaces and
backslashes. Note that a '|' must be escaped twice: once for ":set"
and once for the interpretation of a command. When you use a filter
called "myfilter" do it like this: >
:set makeprg=gmake\ \\\|\ myfilter
< The placeholder "$*" can be given (even multiple times) to specify
where the arguments will be included, for example: >
:set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*}
< This option cannot be set from a |modeline|, for security reasons.
-->
*'matchpairs'* *'mps'*
'matchpairs' 'mps' string (default "(:),{:},[:]")
local to buffer
Characters that form pairs. The |%| command jumps from one to the
other. Currently only single character pairs are allowed, and they
must be different. The characters must be separated by a colon. The
pairs must be separated by a comma. Example for including '<' and '>'
(HTML): >
:set mps+=<:>
<!--
< A more exotic example, to jump between the '=' and ';' in an
assignment, useful for languages like C and Java: >
:au FileType c,cpp,java set mps+==:;
< For a more advanced way of using "%", see the matchit.vim plugin in
the $VIMRUNTIME/macros directory. |add-local-help|
-->
<!--
*'matchtime'* *'mat'*
'matchtime' 'mat' number (default 5)
global
Tenths of a second to show the matching paren, when 'showmatch' is
set. Note that this is not in milliseconds, like other options that
set a time. This is to be compatible with Nvi.
*'maxfuncdepth'* *'mfd'*
'maxfuncdepth' 'mfd' number (default 100)
global
Maximum depth of function calls for user functions. This normally
catches endless recursion. When using a recursive function with
more depth, set 'maxfuncdepth' to a bigger number. But this will use
more memory, there is the danger of failing when memory is exhausted.
See also |:function|.
*'maxmapdepth'* *'mmd'* *E223*
'maxmapdepth' 'mmd' number (default 1000)
global
Maximum number of times a mapping is done without resulting in a
character to be used. This normally catches endless mappings, like
":map x y" with ":map y x". It still does not catch ":map g wg",
because the 'w' is used before the next mapping is done. See also
|key-mapping|.
*'maxmem'* *'mm'*
'maxmem' 'mm' number (default between 256 to 5120 (system
dependent) or half the amount of memory
available)
global
Maximum amount of memory (in Kbyte) to use for one buffer. When this
limit is reached allocating extra memory for a buffer will cause
other memory to be freed. Maximum value 2000000. Use this to work
without a limit. Also see 'maxmemtot'.
*'maxmemtot'* *'mmt'*
'maxmemtot' 'mmt' number (default between 2048 and 10240 (system
dependent) or half the amount of memory
available)
global
Maximum amount of memory (in Kbyte) to use for all buffers together.
Maximum value 2000000. Use this to work without a limit. Also see
'maxmem'.
*'menuitems'* *'mis'*
'menuitems' 'mis' number (default 25)
global
{not available when compiled without the |+menu|
feature}
Maximum number of items to use in a menu. Used for menus that are
generated from a list of items, e.g., the Buffers menu. Changing this
option has no direct effect, the menu must be refreshed first.
*'modeline'* *'ml'* *'nomodeline'* *'noml'*
'modeline' 'ml' boolean (Vim default: on, Vi default: off)
local to buffer
*'modelines'* *'mls'*
'modelines' 'mls' number (default 5)
global
If 'modeline' is on 'modelines' gives the number of lines that is
checked for set commands. If 'modeline' is off or 'modelines' is zero
no lines are checked. See |modeline|.
NOTE: 'modeline' is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'modifiable'* *'ma'* *'nomodifiable'* *'noma'*
'modifiable' 'ma' boolean (default on)
local to buffer
When off the buffer contents cannot be changed. The 'fileformat' and
'fileencoding' options also can't be changed.
Can be reset with the |-M| command line argument.
*'modified'* *'mod'* *'nomodified'* *'nomod'*
'modified' 'mod' boolean (default off)
local to buffer
When on, the buffer is considered to be modified. This option is set
when:
1. A change was made to the text since it was last written. Using the
|undo| command to go back to the original text will reset the
option. But undoing changes that were made before writing the
buffer will set the option again, since the text is different from
when it was written.
2. 'fileformat' or 'fileencoding' is different from its original
value. The original value is set when the buffer is read or
written. A ":set nomodified" command also resets the original
values to the current values and the 'modified' option will be
reset.
When 'buftype' is "nowrite" or "nofile" this option may be set, but
will be ignored.
-->
*'more'* *'nomore'*
'more' boolean (Vim default: on, Vi default: off)
global
When on, listings pause when the whole screen is filled. You will get
the |more-prompt|. When this option is off there are no pauses, the
listing continues until finished.
<!--
*'mouse'* *E538*
'mouse' string (default "", "a" for GUI, MS-DOS and Win32)
global
Enable the use of the mouse. Only works for certain terminals
(xterm, MS-DOS, Win32 |win32-mouse|, qnx pterm, and Linux console
with gpm). For using the mouse in the GUI, see |gui-mouse|.
The mouse can be enabled for different modes:
n Normal mode
v Visual mode
i Insert mode
c Command-line mode
h all previous modes when editing a help file
a all previous modes
r for |hit-enter| and |more-prompt| prompt
A auto-select in Visual mode
Normally you would enable the mouse in all four modes with: >
:set mouse=a
< When the mouse is not enabled, the GUI will still use the mouse for
modeless selection. This doesn't move the text cursor.
See |mouse-using|. Also see |'clipboard'|.
Note: When enabling the mouse in a terminal, copy/paste will use the
"* register if there is access to an X-server. The xterm handling of
the mouse buttons can still be used by keeping the shift key pressed.
Also see the 'clipboard' option.
*'mousefocus'* *'mousef'* *'nomousefocus'* *'nomousef'*
'mousefocus' 'mousef' boolean (default off)
global
{only works in the GUI}
The window that the mouse pointer is on is automatically activated.
When changing the window layout or window focus in another way, the
mouse pointer is moved to the window with keyboard focus. Off is the
default because it makes using the pull down menus a little goofy, as
a pointer transit may activate a window unintentionally.
*'mousehide'* *'mh'* *'nomousehide'* *'nomh'*
'mousehide' 'mh' boolean (default on)
global
{only works in the GUI}
When on, the mouse pointer is hidden when characters are typed.
The mouse pointer is restored when the mouse is moved.
*'mousemodel'* *'mousem'*
'mousemodel' 'mousem' string (default "extend", "popup" for MS-DOS and Win32)
global
Sets the model to use for the mouse. The name mostly specifies what
the right mouse button is used for:
extend Right mouse button extends a selection. This works
like in an xterm.
popup Right mouse button pops up a menu. The shifted left
mouse button extends a selection. This works like
with Microsoft Windows
popup_setpos Like "popup", but the cursor will be moved to the
position where the mouse was clicked, and thus the
selected operation will act upon the clicked object.
If clicking inside a selection, that selection will
be acted upon, ie. no cursor move. This implies of
course, that right clicking outside a selection will
end Visual mode.
Overview of what button does what for each model:
mouse extend popup(_setpos) ~
left click place cursor place cursor
left drag start selection start selection
shift-left search word extend selection
right click extend selection popup menu (place cursor)
right drag extend selection -
middle click paste paste
In the "popup" model the right mouse button produces a pop-up menu.
You need to define this first, see |popup-menu|.
Note that you can further refine the meaning of buttons with mappings.
See |gui-mouse-mapping|. But mappings are NOT used for modeless
selection (because that's handled in the GUI code directly).
The 'mousemodel' option is set by the |:behave| command.
*'mouseshape'* *'mouses'* *E547*
'mouseshape' 'mouses' string (default "i:beam,r:beam,s:updown,sd:cross,
m:no,ml:up-arrow,v:rightup-arrow"
global
{only available when compiled with the |+mouseshape|
feature}
This option tells Vim what the mouse pointer should look like in
different modes. The option is a comma separated list of parts, much
like used for 'guicursor'. Each part consist of a mode/location-list
and an argument-list:
mode-list:shape,mode-list:shape,..
The mode-list is a dash separated list of these modes/locations:
In a normal window: ~
n Normal mode
v Visual mode
ve Visual mode with 'selection' "exclusive" (same as 'v',
if not specified)
o Operator-pending mode
i Insert mode
r Replace mode
Others: ~
c appending to the command-line
ci inserting in the command-line
cr replacing in the command-line
m at the 'Hit ENTER' or 'More' prompts
ml idem, but cursor in the last line
e any mode, pointer below last window
s any mode, pointer on a status line
sd any mode, while dragging a status line
vs any mode, pointer on a vertical separator line
vd any mode, while dragging a vertical separator line
a everywhere
The shape is one of the following:
avail name looks like ~
w x arrow Normal mouse pointer
w x blank no pointer at all (use with care!)
w x beam I-beam
w x updown up-down sizing arrows
w x leftright left-right sizing arrows
w x busy The system's usual busy pointer
w x no The system's usual 'no input' pointer
x udsizing indicates up-down resizing
x lrsizing indicates left-right resizing
x crosshair like a big thin +
x hand1 black hand
x hand2 white hand
x pencil what you write with
x question big ?
x rightup-arrow arrow pointing right-up
w x up-arrow arrow pointing up
x <number> any X11 pointer number (see X11/cursorfont.h)
The "avail" column contains a 'w' if the shape is available for Win32,
x for X11.
Any modes not specifed or shapes not available use the normal mouse
pointer.
Example: >
:set mouseshape=s:udsizing,m:no
< will make the mouse turn to a sizing arrow over the status lines and
indicate no input when the hit-enter prompt is displayed (since
clicking the mouse has no effect in this state.)
*'mousetime'* *'mouset'*
'mousetime' 'mouset' number (default 500)
global
Only for GUI, MS-DOS, Win32 and Unix with xterm. Defines the maximum
time in msec between two mouse clicks for the second click to be
recognized as a multi click.
-->
*'nrformats'* *'nf'*
'nrformats' 'nf' string (default "octal,hex")
local to buffer
This defines what bases Vim will consider for numbers when using the
CTRL-A and CTRL-X commands for adding to and subtracting from a number
respectively; see |CTRL-A| for more info on these commands.
alpha if included, single alphabetical characters will be
incremented or decremented. This is useful for a list with a
letter index a), b), etc.
octal if included, numbers that start with a zero will be considered
to be octal. Example: Using CTRL-A on "007" results in "010".
hex if included, numbers starting with "0x" or "0X" will be
considered to be hexadecimal. Example: Using CTRL-X on
"0x100" results in "0x0ff".
Numbers which simply begin with a digit in the range 1-9 are always
considered decimal. This also happens for numbers that are not
recognized as octal or hex.
<!--
*'number'* *'nu'* *'nonumber'* *'nonu'*
'number' 'nu' boolean (default off)
local to window
Print the line number in front of each line. When the 'n' option is
excluded from 'cpoptions' a wrapped line will not use the column of
line numbers (this is the default when 'compatible' isn't set).
When a long, wrapped line doesn't start with the first character, '-'
characters are put before the number.
See |hl-LineNr| for the highlighting used for the number.
*'osfiletype'* *'oft'* *E366*
'osfiletype' 'oft' string (RISC-OS default: "Text",
others default: "")
local to buffer
{only available when compiled with the |+osfiletype|
feature}
Some operating systems store extra information about files besides
name, datestamp and permissions. This option contains the extra
information, the nature of which will vary between systems.
The value of this option is usually set when the file is loaded, and
use to set the file type when file is written.
It can affect the pattern matching of the automatic commands.
|autocmd-osfiletypes|
*'paragraphs'* *'para'*
'paragraphs' 'para' string (default "IPLPPPQPP LIpplpipbp")
global
Specifies the nroff macros that separate paragraphs. These are pairs
of two letters (see |object-motions|).
*'paste'* *'nopaste'*
'paste' boolean (default off)
global
Put Vim in Paste mode. This is useful if you want to cut or copy
some text from one window and paste it in Vim. This will avoid
unexpected effects.
Setting this option is useful when using Vim in a terminal, where Vim
cannot distinguish between typed text and pasted text. In the GUI, Vim
knows about pasting and will mostly do the right thing without 'paste'
being set. The same is true for a terminal where Vim handles the
mouse clicks itself.
When the 'paste' option is switched on (also when it was already on):
- mapping in Insert mode and Command-line mode is disabled
- abbreviations are disabled
- 'textwidth' is set to 0
- 'wrapmargin' is set to 0
- 'autoindent' is reset
- 'smartindent' is reset
- 'softtabstop' is set to 0
- 'revins' is reset
- 'ruler' is reset
- 'showmatch' is reset
- 'formatoptions' is used like it is empty
These options keep their value, but their effect is disabled:
- 'lisp'
- 'indentexpr'
- 'cindent'
NOTE: When you start editing another file while the 'paste' option is
on, settings from the modelines or autocommands may change the
settings again, causing trouble when pasting text. You might want to
set the 'paste' option again.
When the 'paste' option is reset the mentioned options are restored to
the value before the moment 'paste' was switched from off to on.
Resetting 'paste' before ever setting it does not have any effect.
Since mapping doesn't work while 'paste' is active, you need to use
the 'pastetoggle' option to toggle the 'paste' option with some key.
*'pastetoggle'* *'pt'*
'pastetoggle' 'pt' string (default "")
global
When non-empty, specifies the key sequence that toggles the 'paste'
option. This is like specifying a mapping: >
:map {keys} :set invpaste<CR>
< Where {keys} is the value of 'pastetoggle'.
The difference is that it will work even when 'paste' is set.
'pastetoggle' works in Insert mode and Normal mode, but not in
Command-line mode.
Mappings are checked first, thus overrule 'pastetoggle'. However,
when 'paste' is on mappings are ignored in Insert mode, thus you can do
this: >
:map <F10> :set paste<CR>
:map <F11> :set nopaste<CR>
:imap <F10> <C-O>:set paste<CR>
:imap <F11> <nop>
:set pastetoggle=<F11>
< This will make <F10> start paste mode and <F11> stop paste mode.
Note that typing <F10> in paste mode inserts "<F10>", since in paste
mode everything is inserted literally, except the 'pastetoggle' key
sequence.
*'pex'* *'patchexpr'*
'patchexpr' 'pex' string (default "")
global
{not available when compiled without the |+diff|
feature}
Expression which is evaluated to apply a patch to a file and generate
the resulting new version of the file. See |diff-patchexpr|.
*'patchmode'* *'pm'* *E206*
'patchmode' 'pm' string (default "")
global
When non-empty the oldest version of a file is kept. This can be used
to keep the original version of a file if you are changing files in a
source distribution. Only the first time that a file is written a
copy of the original file will be kept. The name of the copy is the
name of the original file with the string in the 'patchmode' option
appended. This option should start with a dot. Use a string like
".org". 'backupdir' must not be empty for this to work (Detail: The
backup file is renamed to the patchmode file after the new file has
been successfully written, that's why it must be possible to write a
backup file). If there was no file to be backed up, an empty file is
created.
When the 'backupskip' pattern matches, a patchmode file is not made.
Using 'patchmode' for compressed files appends the extension at the
end (e.g., "file.gz.orig"), thus the resulting name isn't always
recognized as a compressed file.
*'path'* *'pa'* *E343* *E345* *E347*
'path' 'pa' string (default on Unix: ".,/usr/include,,"
on OS/2: ".,/emx/include,,"
other systems: ".,,")
global or local to buffer |global-local|
This is a list of directories which will be searched when using the
|gf|, [f, ]f, ^Wf, |:find| and other commands, provided that the file
being searched for has a relative path (not starting with '/'). The
directories in the 'path' option may be relative or absolute.
- Use commas to separate directory names: >
:set path=.,/usr/local/include,/usr/include
< - Spaces can also be used to separate directory names (for backwards
compatibility with version 3.0). To have a space in a directory
name, precede it with an extra backslash, and escape the space: >
:set path=.,/dir/with\\\ space
< - To include a comma in a directory name precede it with an extra
backslash: >
:set path=.,/dir/with\\,comma
< - To search relative to the directory of the current file, use: >
:set path=.
< - To search in the current directory use an empty string between two
commas: >
:set path=,,
< - A directory name may end in a ':' or '/'.
- Environment variables are expanded |:set_env|.
- When using |netrw.vim| URLs can be used. For example, adding
"http://www.vim.org" will make ":find index.html" work.
- Search upwards and downwards in a directory tree:
1) "*" matches a sequence of characters, e.g.: >
:set path=/usr/include/*
< means all subdirectories in /usr/include (but not /usr/include
itself). >
:set path=/usr/*c
< matches /usr/doc and /usr/src.
2) "**" matches a subtree, up to 100 directories deep. Example: >
:set path=/home/user_x/src/**
< means search in the whole subtree under "/home/usr_x/src".
3) If the path ends with a ';', this path is the startpoint
for upward search.
See |file-searching| for more info and exact syntax.
{not available when compiled without the |+path_extra| feature}
- Careful with '\' characters, type two to get one in the option: >
:set path=.,c:\\include
< Or just use '/' instead: >
:set path=.,c:/include
< Don't forget "." or files won't even be found in the same directory as
the file!
The maximum length is limited. How much depends on the system, mostly
it is something like 256 or 1024 characters.
You can check if all the include files are found, using the value of
'path', see |:checkpath|.
The use of |:set+=| and |:set-=| is preferred when adding or removing
directories from the list. This avoids problems when a future version
uses another default. To remove the current directory use: >
:set path-=
< To add the current directory use: >
:set path+=
< To use an environment variable, you probably need to replace the
separator. Here is an example to append $INCL, in which directory
names are separated with a semi-colon: >
:let &path = &path . "," . substitute($INCL, ';', ',', 'g')
< Replace the ';' with a ':' or whatever separator is used. Note that
this doesn't work when $INCL contains a comma or white space.
*'preserveindent'* *'pi'* *'nopreserveindent'* *'nopi'*
'preserveindent' 'pi' boolean (default off)
local to buffer
When changing the indent of the current line, preserve as much of the
indent structure as possible. Normally the indent is replaced by a
series of tabs followed by spaces as required (unless |'expandtab'| is
enabled, in which case only spaces are used). Enabling this option
means the indent will preserve as many existing characters as possible
for indenting, and only add additional tabs or spaces as required.
NOTE: When using ">>" multiple times the resulting indent is a mix of
tabs and spaces. You might not like this.
NOTE: 'preserveindent' is reset when 'compatible' is set.
Also see 'copyindent'.
Use |:retab| to clean up white space.
*'previewheight'* *'pvh'*
'previewheight' 'pvh' number (default 12)
global
{not available when compiled without the |+windows| or
|+quickfix| feature}
Default height for a preview window. Used for |:ptag| and associated
commands. Used for |CTRL-W_}| when no count is given.
*'previewwindow'* *'nopreviewwindow'*
*'pvw'* *'nopvw'* *E590*
'previewwindow' 'pvw' boolean (default off)
local to window
{not available when compiled without the |+windows| or
|+quickfix| feature}
Identifies the preview window. Only one window can have this option
set. It's normally not set directly, but by using one of the commands
|:ptag|, |:pedit|, etc.
*'printdevice'* *'pdev'*
'printdevice' 'pdev' string (default empty)
global
{only available when compiled with the |+printer|
feature}
This defines the name of the printer to be used when the |:hardcopy|
command is issued with a bang (!) to skip the printer selection
dialog. On Win32, it should be the printer name exactly as it appears
in the standard printer dialog.
If the option is empty, then vim will use the system default printer
for ":hardcopy!"
*'printencoding'* *'penc'* *E620*
'printencoding' 'penc' String (default empty, except for:
Windows, OS/2: cp1252,
Macintosh: mac-roman,
VMS: dec-mcs,
HPUX: hp-roman8,
EBCDIC: ebcdic-uk)
global
{only available when compiled with the |+printer|
and |+postscript| features}
Sets the character encoding used when printing. This option tells VIM
which print character encoding file from the "print" directory in
'runtimepath' to use.
This option will accept any value from |encoding-names|. Any
recognized names are converted to VIM standard names - see 'encoding'
for more details. Names not recognized by VIM will just be converted
to lower case and underscores replaced with '-' signs.
If 'printencoding' is empty or VIM cannot find the file then it will
use 'encoding' (if VIM is compiled with |+multi_byte| and it is set an
8-bit encoding) to find the print character encoding file. If VIM is
unable to find a character encoding file then it will use the "latin1"
print character encoding file.
When 'encoding' is set to a multi-byte encoding, VIM will try to
convert characters to the printing encoding for printing (if
'printencoding' is empty then the conversion will be to latin1).
Conversion to a printing encoding other than latin1 will require VIM
to be compiled with the |+iconv| feature. If no conversion is
possible then printing will fail. Any characters that cannot be
converted will be replaced with upside down question marks.
Four print character encoding files are provided to support default
Mac, VMS, HPUX, and EBCDIC character encodings and are used by default
on these platforms. Code page 1252 print character encoding is used
by default on Windows and OS/2 platforms.
*'printexpr'* *'pexpr'*
'printexpr' 'pexpr' String (default: see below)
global
{only available when compiled with the |+printer|
and |+postscript| features}
Expression that is evaluated to print the PostScript produced with
":hardcopy".
The file name to be printed is in |v:fname_in|.
The arguments to the ":hardcopy" command are in |v:cmdarg|.
The expression must take care of deleting the file after printing it.
When there is an error, the expression must return a non-zero number.
If there is no error, return zero or an empty string.
The default for non MS-Windows or VMS systems is to simply use "lpr"
to print the file: >
system('lpr' . (&printdevice == '' ? '' : ' -P' . &printdevice)
. ' ' . v:fname_in) . delete(v:fname_in) + v:shell_error
<
On MS-Windows machines the default is to copy the file to the
currently specified printdevice: >
system('copy' . ' ' . v:fname_in . ' "' . &printdevice . '"')
. delete(v:fname_in)
<
On VMS machines the default is to send the file to either the default
or currently specified printdevice: >
system('print' . (&printdevice == '' ? '' : ' /queue=' .
&printdevice) . ' ' . v:fname_in) . delete(v:fname_in)
<
If you change this option, using a function is an easy way to avoid
having to escape all the spaces. Example: >
:set printexpr=PrintFile(v:fname_in)
:function PrintFile(fname)
: call system("ghostview " . a:fname)
: call delete(a:fname)
: return v:shell_error
:endfunc
< Be aware that some print programs return control before they have read
the file. If you delete the file too soon it will not be printed.
These programs usually offer an option to have them remove the file
when printing is done.
*E365*
If evaluating the expression fails or it results in a non-zero number,
you get an error message. In that case Vim will delete the
file. In the default value for non-MS-Windows a trick is used: Adding
"v:shell_error" will result in a non-zero number when the system()
call fails.
This option cannot be set from a |modeline|, for security reasons.
*'printfont'* *'pfn'* *E613*
'printfont' 'pfn' string (default "courier")
global
{only available when compiled with the |+printer|
feature}
This is the name of the font that will be used for the |:hardcopy|
command's output. It has the same format as the 'guifont' option,
except that only one font may be named, and the special "guifont=*"
syntax is not available.
In the Win32 GUI version this specifies a font name with its extra
attributes, as with the 'guifont' option.
For other systems, only ":h11" is recognized, where "11" is the point
size of the font. When omitted, the points size is 10.
*'printheader'* *'pheader'*
'printheader' 'pheader' string (default "%<%f%h%m%=Page %N")
global
{only available when compiled with the |+printer|
feature}
This defines the format of the header produced in |:hardcopy| output.
The option is defined in the same way as the 'statusline' option.
If Vim has not been compiled with the |+statusline| feature, this
option has no effect and a simple default header is used, which shows
the page number.
*'printoptions'* *'popt'*
'printoptions' 'popt' string (default "")
global
{only available when compiled with |+printer| feature}
This is a comma-separated list of items that control the format of
the output of |:hardcopy|:
left:{spec} left margin (default: 10pc)
right:{spec} right margin (default: 5pc)
top:{spec} top margin (default: 5pc)
bottom:{spec} bottom margin (default: 5pc)
{spec} is a number followed by "in" for
inches, "pt" for points (1 point is 1/72 of an
inch), "mm" for millimetres or "pc" for a
percentage of the media size.
Weird example:
left:2in,top:30pt,right:16mm,bottom:3pc
If the unit is not recognized there is no
error and the default value is used.
header:{nr} Number of lines to reserve for the header.
Only the first line is actually filled, thus
when {nr} is 2 there is one empty line. The
header is formatted according to
'printheader'.
header:0 Do not print a header.
header:2 (default) Use two lines for the header
syntax:n Do not use syntax highlighting. This is
faster and thus useful when printing large
files.
syntax:y Do syntax highlighting.
syntax:a (default) Use syntax highlighting if the printer appears
to be able to print color or grey.
number:y Include line numbers in the printed output.
number:n (default) No line numbers.
wrap:y (default) Wrap long lines.
wrap:n Truncate long lines.
duplex:off Print on one side.
duplex:long (default) Print on both sides (when possible), bind on
long side.
duplex:short Print on both sides (when possible), bind on
short side.
collate:y (default) Collating: 1 2 3, 1 2 3, 1 2 3
collate:n No collating: 1 1 1, 2 2 2, 3 3 3
jobsplit:n (default) Do all copies in one print job
jobsplit:y Do each copy as a separate print job. Useful
when doing N-up postprocessing.
portrait:y (default) Orientation is portrait.
portrait:n Orientation is landscape.
*a4* *letter*
paper:A4 (default) Paper size: A4
paper:{name} Paper size from this table:
{name} size in cm size in inch ~
10x14 25.4 x 35.57 10 x 14
A3 29.7 x 42 11.69 x 16.54
A4 21 x 29.7 8.27 x 11.69
A5 14.8 x 21 5.83 x 8.27
B4 25 x 35.3 10.12 x 14.33
B5 17.6 x 25 7.17 x 10.12
executive 18.42 x 26.67 7.25 x 10.5
folio 21 x 33 8.27 x 13
ledger 43.13 x 27.96 17 x 11
legal 21.59 x 35.57 8.5 x 14
letter 21.59 x 27.96 8.5 x 11
quarto 21.59 x 27.5 8.5 x 10.83
statement 13.97 x 21.59 5.5 x 8.5
tabloid 27.96 x 43.13 11 x 17
formfeed:n (default) Treat form feed characters (0x0c) as a normal
print character.
formfeed:y When a form feed character is encountered,
continue printing of the current line at the
beginning of the first line on a new page.
The item indicated with (default) is used when the item is not
present. The values are not always used, especially when using a
dialog to select the printer and options.
Example: >
:set printoptions=paper:letter,duplex:off
<
*'readonly'* *'ro'* *'noreadonly'* *'noro'*
'readonly' 'ro' boolean (default off)
local to buffer
If on, writes fail unless you use a '!'. Protects you from
accidentally overwriting a file. Default on when Vim is started
in read-only mode ("vim -R") or when the executable is called "view".
When using the ":view" command the 'readonly' option is
set for the newly edited buffer. When using ":w!" the 'readonly'
option is reset for the current buffer.
*'remap'* *'noremap'*
'remap' boolean (default on)
global
Allows for mappings to work recursively. If you do not want this for
a single entry, use the :noremap[!] command.
*'report'*
'report' number (default 2)
global
Threshold for reporting number of lines changed. When the number of
changed lines is more than 'report' a message will be given for most
":" commands. If you want it always, set 'report' to 0.
For the ":substitute" command the number of substitutions is used
instead of the number of lines.
*'restorescreen'* *'rs'* *'norestorescreen'* *'nors'*
'restorescreen' 'rs' boolean (default on)
global
When set, the screen contents is restored when exiting Vim. This also
happens when executing external commands.
For non-Windows Vim: You can set or reset the 't_ti' and 't_te'
options in your .vimrc. To disable restoring:
set t_ti= t_te=
To enable restoring (for an xterm):
set t_ti=^[7^[[r^[[?47h t_te=^[[?47l^[8
(Where ^[ is an <Esc>, type CTRL-V <Esc> to insert it)
*'revins'* *'ri'* *'norevins'* *'nori'*
'revins' 'ri' boolean (default off)
global
{only available when compiled with the |+rightleft|
feature}
Inserting characters in Insert mode will work backwards. See "typing
backwards" |ins-reverse|. This option can be toggled with the CTRL-_
command in Insert mode, when 'allowrevins' is set.
NOTE: This option is reset when 'compatible' or 'paste' is set.
*'rightleft'* *'rl'* *'norightleft'* *'norl'*
'rightleft' 'rl' boolean (default off)
local to window
{only available when compiled with the |+rightleft|
feature}
When on, display orientation becomes right-to-left, i.e., character
that are stored in the file appear from the right to the left.
Using this option, it is possible to edit files for languages that
are written from the right to the left such as Hebrew and Arabic.
This option is per window, so it is possible to edit mixed files
simultaneously, or to view the same file in both ways (this is
useful whenever you have a mixed text file with both right-to-left
and left-to-right strings so that both sets are displayed properly
in different windows). Also see |rileft.txt|.
*'rightleftcmd'* *'rlc'* *'norightleftcmd'* *'norlc'*
'rightleftcmd' 'rlc' string (default "search")
local to window
{only available when compiled with the |+rightleft|
feature}
Each word in this option enables the command line editing to work in
right-to-left mode for a group of commands:
search "/" and "?" commands
This is useful for languages such as Hebrew, Arabic and Farsi.
The 'rightleft' option must be set for 'rightleftcmd' to take effect.
*'ruler'* *'ru'* *'noruler'* *'noru'*
'ruler' 'ru' boolean (default off)
global
{not available when compiled without the
|+cmdline_info| feature}
Show the line and column number of the cursor position, separated by a
comma. When there is room, the relative position of the displayed
text in the file is shown on the far right:
Top first line is visible
Bot last line is visible
All first and last line are visible
45% relative position in the file
If 'rulerformat' is set, it will determine the contents of the ruler.
Each window has its own ruler. If a window has a status line, the
ruler is shown there. Otherwise it is shown in the last line of the
screen. If the statusline is given by 'statusline' (ie. not empty),
this option takes precedence over 'ruler' and 'rulerformat'
If the number of characters displayed is different from the number of
bytes in the text (e.g., for a TAB or a multi-byte character), both
the text column (byte number) and the screen column are shown,
separated with a dash.
For an empty line "0-1" is shown.
For an empty buffer the line number will also be zero: "0,0-1".
This option is reset when the 'paste' option is set.
If you don't want to see the ruler all the time but want to know where
you are, use "g CTRL-G" |g_CTRL-G|.
NOTE: This option is reset when 'compatible' is set.
*'rulerformat'* *'ruf'*
'rulerformat' 'ruf' string (default empty)
global
{not available when compiled without the |+statusline|
feature}
When this option is not empty, it determines the content of the ruler
string, as displayed for the 'ruler' option.
The format of this option, is like that of 'statusline'.
The default ruler width is 17 characters. To make the ruler 15
characters wide, put "%15(" at the start and "%)" at the end.
Example: >
:set rulerformat=%15(%c%V\ %p%%%)
<
*'runtimepath'* *'rtp'* *vimfiles*
'runtimepath' 'rtp' string (default:
Unix: "$HOME/.vim,

$HOME/.vim/after"
Amiga: "home:vimfiles,

This is a list of directories which will be searched for runtime
files:
filetype.vim filetypes by file name |new-filetype|
scripts.vim filetypes by file contents |new-filetype-scripts|
colors/ color scheme files |:colorscheme|
compiler/ compiler files |:compiler|
doc/ documentation |write-local-help|
ftplugin/ filetype plugins |write-filetype-plugin|
indent/ indent scripts |indent-expression|
keymap/ key mapping files |mbyte-keymap|
lang/ menu translations |:menutrans|
menu.vim GUI menus |menu.vim|
plugin/ plugin scripts |write-plugin|
syntax/ syntax files |mysyntaxfile|
tutor/ files for vimtutor |tutor|
And any other file searched for with the |:runtime| command.
The defaults for most systems are setup to search five locations:
1. In your home directory, for your personal preferences.
2. In a system-wide Vim directory, for preferences from the system
administrator.
3. In $VIMRUNTIME, for files distributed with Vim.
*after-directory*
4. In the "after" directory in the system-wide Vim directory. This is
for the system administrator to overrule or add to the distributed
defaults (rarely needed)
5. In the "after" directory in your home directory. This is for
personal preferences to overrule or add to the distributed defaults
or system-wide settings (rarely needed).
Note that, unlike 'path', no wildcards like "**" are allowed. Normal
wildcards are allowed, but can significantly slow down searching for
runtime files. For speed, use as few items as possible and avoid
wildcards.
See |:runtime|.
Example: >
:set runtimepath=~/vimruntime,/mygroup/vim,$VIMRUNTIME
< This will use the directory "~/vimruntime" first (containing your
personal Vim runtime files), then "/mygroup/vim" (shared between a
group of people) and finally "$VIMRUNTIME" (the distributed runtime
files).
You probably should always include $VIMRUNTIME somewhere, to use the
distributed runtime files. You can put a directory before $VIMRUNTIME
to find files which replace a distributed runtime files. You can put
a directory after $VIMRUNTIME to find files which add to distributed
runtime files.
This option cannot be set from a |modeline|, for security reasons.

*'scroll'* *'scr'*
'scroll' 'scr' number (default: half the window height)
local to window
Number of lines to scroll with CTRL-U and CTRL-D commands. Will be
set to half the number of lines in the window when the window size
changes. If you give a count to the CTRL-U or CTRL-D command it will
be used as the new value for 'scroll'. Reset to half the window
height with ":set scroll=0".
<!--
*'scrollbind'* *'scb'* *'noscrollbind'* *'noscb'*
'scrollbind' 'scb' boolean (default off)
local to window
{not available when compiled without the |+scrollbind|
feature}
See also |scroll-binding|. When this option is set, the current
window scrolls as other scrollbind windows (windows that also have
this option set) scroll. This option is useful for viewing the
differences between two versions of a file, see 'diff'.
See |'scrollopt'| for options that determine how this option should be
interpreted.
This option is mostly reset when splitting a window to edit another
file. This means that ":split | edit file" results in two windows
with scroll-binding, but ":split file" does not.
-->
*'scrolljump'* *'sj'*
'scrolljump' 'sj' number (default 1)
global
Minimal number of lines to scroll when the cursor gets off the
screen (e.g., with "j"). Not used for scroll commands (e.g., CTRL-E,
CTRL-D). Useful if your terminal scrolls very slowly.
*'scrolloff'* *'so'*
'scrolloff' 'so' number (default 0)
global
Minimal number of screen lines to keep above and below the cursor.
This will make some context visible around where you are working. If
you set it to a very large value (999) the cursor line will always be
in the middle of the window (except at the start or end of the file or
when long lines wrap).
For scrolling horizontallly see 'sidescrolloff'.
<!--
*'scrollopt'* *'sbo'*
'scrollopt' 'sbo' string (default "ver,jump")
global
{not available when compiled without the |+scrollbind|
feature}
This is a comma-separated list of words that specifies how
'scrollbind' windows should behave.
The following words are available:
ver Bind vertical scrolling for 'scrollbind' windows
hor Bind horizontal scrolling for 'scrollbind' windows
jump Applies to the offset between two windows for vertical
scrolling. This offset is the difference in the first
displayed line of the bound windows. When moving
around in a window, another 'scrollbind' window may
reach a position before the start or after the end of
the buffer. The offset is not changed though, when
moving back the 'scrollbind' window will try to scroll
to the desired position when possible.
When now making that window the current one, two
things can be done with the relative offset:
1. When "jump" is not included, the relative offset is
adjusted for the scroll position in the new current
window. When going back to the other window, the
the new relative offset will be used.
2. When "jump" is included, the other windows are
scrolled to keep the same relative offset. When
going back to the other window, it still uses the
same relative offset.
Also see |scroll-binding|.
*'sections'* *'sect'*
'sections' 'sect' string (default "SHNHH HUnhsh")
global
Specifies the nroff macros that separate sections. These are pairs of
two letters (See |object-motions|). The default makes a section start
at the nroff macros ".SH", ".NH", ".H", ".HU", ".nh" and ".sh".
*'secure'* *'nosecure'* *E523*
'secure' boolean (default off)
global
When on, ":autocmd", shell and write commands are not allowed in
".vimrc" and ".exrc" in the current directory and map commands are
displayed. Switch it off only if you know that you will not run into
problems, or when the 'exrc' option is off. On Unix this option is
only used if the ".vimrc" or ".exrc" is not owned by you. This can be
dangerous if the systems allows users to do a "chown". You better set
'secure' at the end of your ~/.vimrc then.
This option cannot be set from a |modeline|, for security reasons.
-->
*'selection'* *'sel'*
'selection' 'sel' string (default "inclusive")
global
This option defines the behavior of the selection. It is only used
in Visual and Select mode.
Possible values:
value past line inclusive ~
old no yes
inclusive yes yes
exclusive yes no
"past line" means that the cursor is allowed to be positioned one
character past the line.
"inclusive" means that the last character of the selection is included
in an operation. For example, when "x" is used to delete the
selection.
<!--
*'selectmode'* *'slm'*
'selectmode' 'slm' string (default "")
global
This is a comma separated list of words, which specifies when to start
Select mode instead of Visual mode, when a selection is started.
Possible values:
mouse when using the mouse
key when using shifted special keys
cmd when using "v", "V" or CTRL-V
See |Select-mode|.
The 'selectmode' option is set by the |:behave| command.
*'sessionoptions'* *'ssop'*
'sessionoptions' 'ssop' string (default: "blank,buffers,curdir,folds,
help,options,winsize")
global
{not available when compiled without the +mksession
feature}
Changes the effect of the |:mksession| command. It is a comma
separated list of words. Each word enables saving and restoring
something:
word save and restore ~
blank empty windows
buffers hidden and unloaded buffers, not just those in windows
curdir the current directory
folds manually created folds, opened/closed folds and local
fold options
globals global variables that start with an uppercase letter
and contain at least one lowercase letter.
help the help window
localoptions options and mappings local to a window or buffer (not
global values for local options)
options all options and mappings (also global values for local
options)
resize size of the Vim window: 'lines' and 'columns'
sesdir the directory in which the session file is located
will become the current directory (useful with
projects accessed over a network from different
systems)
slash backslashes in file names replaced with forward
slashes
unix with Unix end-of-line format (single <NL>), even when
on Windows or DOS
winpos position of the whole Vim window
winsize window sizes
Don't include both "curdir" and "sesdir".
When "curdir" nor "sesdir" is included, file names are stored with
absolute paths.
"slash" and "unix" are useful on Windows when sharing session files
with Unix. The Unix version of Vim cannot source dos format scripts,
but the Windows version of Vim can source unix format scripts.
*'shell'* *'sh'* *E91*
'shell' 'sh' string (default $SHELL or "sh",
MS-DOS and Win32: "command.com" or
"cmd.exe", OS/2: "cmd")
global
Name of the shell to use for ! and :! commands. When changing the
value also check these options: 'shelltype', 'shellpipe', 'shellslash'
'shellredir', 'shellquote', 'shellxquote' and 'shellcmdflag'.
It is allowed to give an argument to the command, e.g. "csh -f".
See |option-backslash| about including spaces and backslashes.
Environment variables are expanded |:set_env|.
If the name of the shell contains a space, you might need to enclose
it in quotes. Example: >
:set shell=\"c:\program\ files\unix\sh.exe\"\ -f
< Note the backslash before each quote (to avoid starting a comment) and
each space (to avoid ending the option value). Also note that the
"-f" is not inside the quotes, because it is not part of the command
name. And Vim automagically recognizes the backslashes that are path
separators.
For Dos 32 bits (DJGPP), you can set the $DJSYSFLAGS environment
variable to change the way external commands are executed. See the
libc.inf file of DJGPP.
Under MS-Windows, when the executable ends in ".com" it must be
included. Thus setting the shell to "command.com" or "4dos.com"
works, but "command" and "4dos" do not work for all commands (e.g.,
filtering).
For unknown reasons, when using "4dos.com" the current directory is
changed to "C:\". To avoid this set 'shell' like this: >
:set shell=command.com\ /c\ 4dos
< This option cannot be set from a |modeline|, for security reasons.
*'shellcmdflag'* *'shcf'*
'shellcmdflag' 'shcf' string (default: "-c", MS-DOS and Win32, when 'shell'
does not contain "sh" somewhere: "/c")
global
Flag passed to the shell to execute "!" and ":!" commands; e.g.,
"bash.exe -c ls" or "command.com /c dir". For the MS-DOS-like
systems, the default is set according to the value of 'shell', to
reduce the need to set this option by the user. It's not used for
OS/2 (EMX figures this out itself). See |option-backslash| about
including spaces and backslashes. See |dos-shell|.
This option cannot be set from a |modeline|, for security reasons.
*'shellpipe'* *'sp'*
'shellpipe' 'sp' string (default ">", "| tee", "|& tee" or "2>&1| tee")
global
{not available when compiled without the |+quickfix|
feature}
String to be used to put the output of the ":make" command in the
error file. See also |:make_makeprg|. See |option-backslash| about
including spaces and backslashes.
The name of the temporary file can be represented by "%s" if necessary
(the file name is appended automatically if no %s appears in the value
of this option).
For the Amiga and MS-DOS the default is ">". The output is directly
saved in a file and not echoed to the screen.
For Unix the default it "| tee". The stdout of the compiler is saved
in a file and echoed to the screen. If the 'shell' option is "csh" or
"tcsh" after initializations, the default becomes "|& tee". If the
'shell' option is "sh", "ksh", "zsh" or "bash" the default becomes
"2>&1| tee". This means that stderr is also included.
The initialization of this option is done after reading the ".vimrc"
and the other initializations, so that when the 'shell' option is set
there, the 'shellpipe' option changes automatically, unless it was
explicitly set before.
When 'shellpipe' is set to an empty string, no redirection of the
":make" output will be done. This is useful if you use a 'makeprg'
that writes to 'makeef' by itself. If you want no piping, but do
want to include the 'makeef', set 'shellpipe' to a single space.
Don't forget to precede the space with a backslash: ":set sp=\ ".
In the future pipes may be used for filtering and this option will
become obsolete (at least for Unix).
This option cannot be set from a |modeline|, for security reasons.
*'shellquote'* *'shq'*
'shellquote' 'shq' string (default: ""; MS-DOS and Win32, when 'shell'
contains "sh" somewhere: "\"")
global
Quoting character(s), put around the command passed to the shell, for
the "!" and ":!" commands. The redirection is kept outside of the
quoting. See 'shellxquote' to include the redirection. It's
probably not useful to set both options.
This is an empty string by default. Only known to be useful for
third-party shells on MS-DOS-like systems, such as the MKS Korn Shell
or bash, where it should be "\"". The default is adjusted according
the value of 'shell', to reduce the need to set this option by the
user. See |dos-shell|.
This option cannot be set from a |modeline|, for security reasons.
*'shellredir'* *'srr'*
'shellredir' 'srr' string (default ">", ">&" or ">%s 2>&1")
global
String to be used to put the output of a filter command in a temporary
file. See also |:!|. See |option-backslash| about including spaces
and backslashes.
The name of the temporary file can be represented by "%s" if necessary
(the file name is appended automatically if no %s appears in the value
of this option).
The default is ">". For Unix, if the 'shell' option is "csh", "tcsh"
or "zsh" during initializations, the default becomes ">&". If the
'shell' option is "sh", "ksh" or "bash" the default becomes
">%s 2>&1". This means that stderr is also included.
For Win32, the Unix checks are done and additionally "cmd" is checked
for, which makes the default ">%s 2>&1". Also, the same names with
".exe" appended are checked for.
The initialization of this option is done after reading the ".vimrc"
and the other initializations, so that when the 'shell' option is set
there, the 'shellredir' option changes automatically unless it was
explicitly set before.
In the future pipes may be used for filtering and this option will
become obsolete (at least for Unix).
This option cannot be set from a |modeline|, for security reasons.
*'shellslash'* *'ssl'* *'noshellslash'* *'nossl'*
'shellslash' 'ssl' boolean (default off)
global
When set, a forward slash is used when expanding file names. This is
useful when a Unix-like shell is used instead of command.com or
cmd.exe. Backward slashes can still be typed, but they are changed to
forward slashes by Vim.
Note that setting or resetting this option has no effect for some
existing file names, thus this option needs to be set before opening
any file for best results. This might change in the future.
'shellslash' only works when a backslash can be used as a path
separator. To test if this is so use: >
if exists('+shellslash')
<
*'shelltype'* *'st'*
'shelltype' 'st' number (default 0)
global
On the Amiga this option influences the way how the commands work
which use a shell.
0 and 1: always use the shell
2 and 3: use the shell only to filter lines
4 and 5: use shell only for ':sh' command
When not using the shell, the command is executed directly.
0 and 2: use "shell 'shellcmdflag' cmd" to start external commands
1 and 3: use "shell cmd" to start external commands
*'shellxquote'* *'sxq'*
'shellxquote' 'sxq' string (default: "";
for Win32, when 'shell' contains "sh"
somewhere: "\""
for Unix, when using system(): "\"")
global
Quoting character(s), put around the command passed to the shell, for
the "!" and ":!" commands. Includes the redirection. See
'shellquote' to exclude the redirection. It's probably not useful
to set both options.
This is an empty string by default. Known to be useful for
third-party shells when using the Win32 version, such as the MKS Korn
Shell or bash, where it should be "\"". The default is adjusted
according the value of 'shell', to reduce the need to set this option
by the user. See |dos-shell|.
This option cannot be set from a |modeline|, for security reasons.
*'shiftround'* *'sr'* *'noshiftround'* *'nosr'*
'shiftround' 'sr' boolean (default off)
global
Round indent to multiple of 'shiftwidth'. Applies to > and <
commands. CTRL-T and CTRL-D in Insert mode always round the indent to
a multiple of 'shiftwidth' (this is Vi compatible).
NOTE: This option is reset when 'compatible' is set.
*'shiftwidth'* *'sw'*
'shiftwidth' 'sw' number (default 8)
local to buffer
Number of spaces to use for each step of (auto)indent. Used for
|'cindent'|, |>>|, |<<|, etc.
*'shortmess'* *'shm'*
'shortmess' 'shm' string (Vim default "filnxtToO", Vi default: "")
global
This option helps to avoid all the |hit-enter| prompts caused by file
messages, for example with CTRL-G, and to avoid some other messages.
It is a list of flags:
flag meaning when present ~
f use "(3 of 5)" instead of "(file 3 of 5)"
i use "[noeol]" instead of "[Incomplete last line]"
l use "999L, 888C" instead of "999 lines, 888 characters"
m use "[+]" instead of "[Modified]"
n use "[New]" instead of "[New File]"
r use "[RO]" instead of "[readonly]"
w use "[w]" instead of "written" for file write message
and "[a]" instead of "appended" for ':w >> file' command
x use "[dos]" instead of "[dos format]", "[unix]" instead of
"[unix format]" and "[mac]" instead of "[mac format]".
a all of the above abbreviations
o overwrite message for writing a file with subsequent message
for reading a file (useful for ":wn" or when 'autowrite' on)
O message for reading a file overwrites any previous message.
Also for quickfix message (e.g., ":cn").
s don't give "search hit BOTTOM, continuing at TOP" or "search
hit TOP, continuing at BOTTOM" messages
t truncate file message at the start if it is too long to fit
on the command-line, "<" will appear in the left most column.
Ignored in Ex mode.
T truncate other messages in the middle if they are too long to
fit on the command line. "..." will appear in the middle.
Ignored in Ex mode.
W don't give "written" or "[w]" when writing a file
A don't give the "ATTENTION" message when an existing swap file
is found.
I don't give the intro message when starting Vim |:intro|.
This gives you the opportunity to avoid that a change between buffers
requires you to hit <Enter>, but still gives as useful a message as
possible for the space available. To get the whole message that you
would have got with 'shm' empty, use ":file!"
Useful values:
shm= No abbreviation of message.
shm=a Abbreviation, but no loss of information.
shm=at Abbreviation, and truncate message when necessary.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'shortname'* *'sn'* *'noshortname'* *'nosn'*
'shortname' 'sn' boolean (default off)
local to buffer
Filenames are assumed to be 8 characters plus one extension of 3
characters. Multiple dots in file names are not allowed. When this
option is on, dots in file names are replaced with underscores when
adding an extension (".~" or ".swp"). This option is not available
for MS-DOS, because then it would always be on. This option is useful
when editing files on an MS-DOS compatible filesystem, e.g., messydos
or crossdos. When running the Win32 GUI version under Win32s, this
option is always on by default.
*'showbreak'* *'sbr'* *E595*
'showbreak' 'sbr' string (default "")
global
{not available when compiled without the |+linebreak|
feature}
String to put at the start of lines that have been wrapped. Useful
values are "> " or "+++ ".
Only printable single-cell characters are allowed, excluding <Tab> and
comma (in a future version the comma might be used to separate the
part that is shown at the end and at the start of a line).
The characters are highlighted according to the '@' flag in
'highlight'.
Note that tabs after the showbreak will be displayed differently.
If you want the 'showbreak' to appear in between line numbers, add the
"n" flag to 'cpoptions'.
*'showcmd'* *'sc'* *'noshowcmd'* *'nosc'*
'showcmd' 'sc' boolean (Vim default: on, off for Unix, Vi default:
off)
global
{not available when compiled without the
|+cmdline_info| feature}
Show (partial) command in status line. Set this option off if your
terminal is slow.
In Visual mode the size of the selected area is shown:
- When selecting characters within a line, the number of characters.
- When selecting more than one line, the number of lines.
- When selecting a block, the size in screen characters: linesxcolumns.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'showfulltag'* *'sft'* *'noshowfulltag'* *'nosft'*
'showfulltag' 'sft' boolean (default off)
global
When completing a word in insert mode (see |ins-completion|) from the
tags file, show both the tag name and a tidied-up form of the search
pattern (if there is one) as possible matches. Thus, if you have
matched a C function, you can see a template for what arguments are
required (coding style permitting).
*'showmatch'* *'sm'* *'noshowmatch'* *'nosm'*
'showmatch' 'sm' boolean (default off)
global
When a bracket is inserted, briefly jump to the matching one. The
jump is only done if the match can be seen on the screen. The time to
show the match can be set with 'matchtime'.
A Beep is given if there is no match (no matter if the match can be
seen or not). This option is reset when the 'paste' option is set.
When the 'm' flag is not included in 'cpoptions', typing a character
will immediately move the cursor back to where it belongs.
See the "sm" field in 'guicursor' for setting the cursor shape and
blinking when showing the match.
Note: For the use of the short form parental guidance is advised.
-->
*'showmode'* *'smd'* *'noshowmode'* *'nosmd'*
'showmode' 'smd' boolean (default: on)
global
If in Insert, Replace or Visual mode put a message on the last line.
Use the 'M' flag in 'highlight' to set the type of highlighting for
this message.
<!--
When |XIM| may be used the message will include "XIM". But this
doesn't mean XIM is really active, especially when 'imactivatekey' is
not set.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
-->
*'sidescroll'* *'ss'*
'sidescroll' 'ss' number (default 0)
global
The minimal number of columns to scroll horizontally. Used only when
the 'wrap' option is off and the cursor is moved off of the screen.
When it is zero the cursor will be put in the middle of the screen.
Not used for "zh" and "zl" commands.
*'sidescrolloff'* *'siso'*
'sidescrolloff' 'siso' number (default 0)
global
The minimal number of screen columns to keep to the left and to the
right of the cursor if 'nowrap' is set. Setting this option to a value
greater than 0 while having |'sidescroll'| also at a non-zero value
makes some context visible in the line you are scrolling in
horizontally (except at the end and beginning of the line). Setting
this option to a large value (like 999) has the effect of keeping the
cursor horizontally centered in the window, as long as one does not
come too close to the beginning or end of the line.
<!--
NOTE: This option is set to 0 when 'compatible' is set.
Example: Try this together with 'sidescroll' and 'listchars' as
in the following example to never allow the cursor to move
onto the "extends" character:
:set nowrap sidescroll=1 listchars=extends:>,precedes:<
:set sidescrolloff=1
-->
*'smartcase'* *'scs'* *'nosmartcase'* *'noscs'*
'smartcase' 'scs' boolean (default off)
global
Override the 'ignorecase' option if the search pattern contains upper
case characters. Only used when the search pattern is typed and
'ignorecase' option is on. Used for the commands "/", "?", "n", "N",
":g" and ":s". Not used for "*", "#", "gd", tag search, etc.. After
"*" and "#" you can make 'smartcase' used by doing a "/" command,
recalling the search pattern from history and hitting <Enter>.
<!--
*'smartindent'* *'si'* *'nosmartindent'* *'nosi'*
'smartindent' 'si' boolean (default off)
local to buffer
{not available when compiled without the
|+smartindent| feature}
Do smart autoindenting when starting a new line. Works for C-like
programs, but can also be used for other languages. 'cindent' does
something like this, works better in most cases, but is more strict,
see |C-indenting|. When 'cindent' is on, setting 'si' has no effect.
'indentexpr' is a more advanced alternative.
Normally 'autoindent' should also be on when using 'smartindent'.
An indent is automatically inserted:
- After a line ending in '{'.
- After a line starting with a keyword from 'cinwords'.
- Before a line starting with '}' (only with the "O" command).
When typing '}' as the first character in a new line, that line is
given the same indent as the matching '{'.
When typing '#' as the first character in a new line, the indent for
that line is removed, the '#' is put in the first column. The indent
is restored for the next line. If you don't want this, use this
mapping: ":inoremap # X^H#", where ^H is entered with CTRL-V CTRL-H.
When using the ">>" command, lines starting with '#' are not shifted
right.
NOTE: 'smartindent' is reset when 'compatible' is set. When 'paste'
is set smart indenting is disabled.
*'smarttab'* *'sta'* *'nosmarttab'* *'nosta'*
'smarttab' 'sta' boolean (default off)
global
When on, a <Tab> in front of a line inserts blanks according to
'shiftwidth'. 'tabstop' is used in other places. A <BS> will delete
a 'shiftwidth' worth of space at the start of the line.
When off a <Tab> always inserts blanks according to 'tabstop'.
'shiftwidth' is only used for shifting text left or right
|shift-left-right|.
What gets inserted (a Tab or spaces) depends on the 'expandtab'
option. Also see |ins-expandtab|. When 'expandtab' is not set, the
number of spaces minimized by using <Tab>s.
NOTE: This option is reset when 'compatible' is set.
*'softtabstop'* *'sts'*
'softtabstop' 'sts' number (default 0)
local to buffer
Number of spaces that a <Tab> counts for while performing editing
operations, like inserting a <Tab> or using <BS>. It "feels" like
<Tab>s are being inserted, while in fact a mix of spaces and <Tab>s is
used. This is useful to keep the 'ts' setting at its standard value
of 8, while being able to edit like it is set to 'sts'. However,
commands like "x" still work on the actual characters.
When 'sts' is zero, this feature is off.
'softtabstop' is set to 0 when the 'paste' option is set.
See also |ins-expandtab|. When 'expandtab' is not set, the number of
spaces is minimized by using <Tab>s.
NOTE: This option is set to 0 when 'compatible' is set.
*'splitbelow'* *'sb'* *'nosplitbelow'* *'nosb'*
'splitbelow' 'sb' boolean (default off)
global
{not available when compiled without the +windows
feature}
When on, splitting a window will put the new window below the current
one. |:split|
*'splitright'* *'spr'* *'nosplitright'* *'nospr'*
'splitright' 'spr' boolean (default off)
global
{not available when compiled without the +vertsplit
feature}
When on, splitting a window will put the new window right of the
current one. |:vsplit|
*'startofline'* *'sol'* *'nostartofline'* *'nosol'*
'startofline' 'sol' boolean (default on)
global
When "on" the commands listed below move the cursor to the first
blank of the line. When off the cursor is kept in the same column
(if possible). This applies to the commands: CTRL-D, CTRL-U, CTRL-B,
CTRL-F, "G", "H", "M", "L", , and to the commands "d", "<<" and ">>"
with a linewise operator, with "%" with a count and to buffer changing
commands (CTRL-^, :bnext, :bNext, etc.). Also for an Ex command that
only has a line number, e.g., ":25" or ":+".
In case of buffer changing commands the cursor is placed at the column
where it was the last time the buffer was edited.
NOTE: This option is set when 'compatible' is set.
*'statusline'* *'stl'* *E540* *E541* *E542*
'statusline' 'stl' string (default empty)
global
{not available when compiled without the |+statusline|
feature}
When nonempty, this option determines the content of the status line.
Also see |status-line|.
The option consists of printf style '%' items interspersed with
normal text. Each status line item is of the form:
%-0{minwid}.{maxwid}{item}
All fields except the {item} is optional. A single percent sign can
be given as "%%".
Note that the only effect of 'ruler' when this option is set (and
'laststatus' is 2) is controlling the output of |CTRL-G|.
field meaning ~
- Left justify the item. The default is right justified
when minwid is larger than the length of the item.
0 Leading zeroes in numeric items. Overridden by '-'.
minwid Minimum width of the item, padding as set by '-' & '0'.
Value must be 50 or less.
maxwid Maximum width of the item. Truncation occurs with a '<'
on the left for text items. Numeric items will be
shifted down to maxwid-2 digits followed by '>'number
where number is the amount of missing digits, much like
an exponential notation.
item A one letter code as described below.
Following is a description of the possible statusline items. The
second character in "item" is the type:
N for number
S for string
F for flags as described below
- not applicable
item meaning ~
f S Path to the file in the buffer, relative to current directory.
F S Full path to the file in the buffer.
t S File name (tail) of file in the buffer.
m F Modified flag, text is " [+]" or " [-]" if 'modifiable' is off.
M F Modified flag, text is ",+" or ",-".
r F Readonly flag, text is " [RO]".
R F Readonly flag, text is ",RO".
h F Help buffer flag, text is " [help]".
H F Help buffer flag, text is ",HLP".
w F Preview window flag, text is " [Preview]".
W F Preview window flag, text is ",PRV".
y F Type of file in the buffer, e.g., " [vim]". See 'filetype'.
Y F Type of file in the buffer, e.g., ",VIM". See 'filetype'.
{not available when compiled without |+autocmd| feature}
k S Value of "b:keymap_name" or 'keymap' when |:lmap| mappings are
being used: "<keymap>"
n N Buffer number.
b N Value of byte under cursor.
B N As above, in hexadecimal.
o N Byte number in file of byte under cursor, first byte is 1.
Mnemonic: Offset from start of file (with one added)
{not available when compiled without |+byte_offset| feature}
O N As above, in hexadecimal.
N N Printer page number. (Only works in the 'printheader' option.)
l N Line number.
L N Number of lines in buffer.
c N Column number.
v N Virtual column number.
V N Virtual column number as -{num}. Not displayed if equal to 'c'.
p N Percentage through file in lines as in |CTRL-G|.
P S Percentage through file of displayed window. This is like the
percentage described for 'ruler'. Always 3 in length.
a S Argument list status as in default title. ({current} of {max})
Empty if the argument file count is zero or one.
{ NF Evaluate expression between '{' and '}' and substitute result.
( - Start of item group. Can be used for setting the width and
alignment of a section. Must be followed by %) somewhere.
) - End of item group. No width fields allowed.
< - Where to truncate line if too long. Default is at the start.
No width fields allowed.
= - Separation point between left and right aligned items.
No width fields allowed.
* - Set highlight group to User{N}, where {N} is taken from the
minwid field. eg. %1*. Restore normal highlight with %* or %0*.
The difference between User{N} and StatusLine will be applied
to StatusLineNC for the statusline of non-current windows.
The number N must be between 1 and 9. See |hl-User1..9|
Display of flags are controlled by the following heuristic:
If a flag text starts with comma it is assumed that it wants to
separate itself from anything but preceding plaintext. If it starts
with a space it is assumed that it wants to separate itself from
anything but other flags. That is: A leading comma is removed if the
preceding character stems from plaintext. A leading space is removed
if the preceding character stems from another active flag. This will
make a nice display when flags are used like in the examples below.
When all items in a group becomes an empty string (ie. flags that are
not set) and a minwid is not set for the group, the whole group will
become empty. This will make a group like the following disappear
completely from the statusline when none of the flags are set. >
:set statusline=...%(\ [%M%R%H]%)...
<
Beware that an expression is evaluated each and every time the status
line is displayed. The current buffer and current window will be set
temporarily to that of the window (and buffer) whose statusline is
currently being drawn. The expression will evaluate in this context.
The variable "actual_curbuf" is set to the 'bufnr()' number of the
real current buffer. The expression is evaluated in the |sandbox|.
If the statusline is not updated when you want it (e.g., after setting
a variable that's used in an expression), you can force an update by
setting an option without changing its value. Example: >
:let &ro = &ro
< A result of all digits is regarded a number for display purposes.
Otherwise the result is taken as flag text and applied to the rules
described above.
Watch out for errors in expressions. They may render Vim unusable !
If you are stuck, hold down ':' or 'Q' to get a prompt, then quit and
edit your .vimrc or whatever with "vim -u NONE" to get it right.
Examples:
Emulate standard status line with 'ruler' set >
:set statusline=%<%f\ %h%m%r%=%-14.(%l,%c%V%)\ %P
< Similar, but add ascii value of char under the cursor (like "ga") >
:set statusline=%<%f%h%m%r%=%b\ 0x%B\ \ %l,%c%V\ %P
< Display byte count and byte value, modified flag in red. >
:set statusline=%<%f%=\ [%1*%M%*%n%R%H]\ %-19(%3l,%02c%03V%)%O'%02b'
:hi User1 term=inverse,bold cterm=inverse,bold ctermfg=red
< Display a ,GZ flag if a compressed file is loaded >
:set statusline=...%r%{VarExists('b:gzflag','\ [GZ]')}%h...
< In the |:autocmd|'s: >
:let b:gzflag = 1
< And: >
:unlet b:gzflag
< And define this function: >
:function VarExists(var, val)
: if exists(a:var) | return a:val | else | return '' | endif
:endfunction
<
*'suffixes'* *'su'*
'suffixes' 'su' string (default ".bak,~,.o,.h,.info,.swp,.obj")
global
Files with these suffixes get a lower priority when multiple files
match a wildcard. See |suffixes|. Commas can be used to separate the
suffixes. Spaces after the comma are ignored. A dot is also seen as
the start of a suffix. To avoid a dot or comma being recognized as a
separator, precede it with a backslash (see |option-backslash| about
including spaces and backslashes).
See 'wildignore' for completely ignoring files.
The use of |:set+=| and |:set-=| is preferred when adding or removing
suffixes from the list. This avoids problems when a future version
uses another default.
*'suffixesadd'* *'sua'*
'suffixesadd' 'sua' string (default "")
local to buffer
{not available when compiled without the
|+file_in_path| feature}
Comma separated list of suffixes, which are used when searching for a
file for the "gf", "[I", etc. commands. Example: >
:set suffixesadd=.java
<
*'swapfile'* *'swf'* *'noswapfile'* *'noswf'*
'swapfile' 'swf' boolean (default on)
local to buffer
Use a swapfile for the buffer. This option can be reset when a
swapfile is not wanted for a specific buffer. For example, with
confidential information that even root must not be able to access.
Careful: All text will be in memory:
- Don't use this for big files.
- Recovery will be impossible!
A swapfile will only be present when |'updatecount'| is non-zero and
'swapfile' is set.
When 'swapfile' is reset, the swap file for the current buffer is
immediately deleted. When 'swapfile' is set, and 'updatecount' is
non-zero, a swap file is immediately created.
Also see |swap-file| and |'swapsync'|.
This option is used together with 'bufhidden' and 'buftype' to
specify special kinds of buffers. See |special-buffers|.
*'swapsync'* *'sws'*
'swapsync' 'sws' string (default "fsync")
global
When this option is not empty a swap file is synced to disk after
writing to it. This takes some time, especially on busy unix systems.
When this option is empty parts of the swap file may be in memory and
not written to disk. When the system crashes you may lose more work.
On Unix the system does a sync now and then without Vim asking for it,
so the disadvantage of setting this option off is small. On some
systems the swap file will not be written at all. For a unix system
setting it to "sync" will use the sync() call instead of the default
fsync(), which may work better on some systems.
*'switchbuf'* *'swb'*
'switchbuf' 'swb' string (default "")
global
This option controls the behavior when switching between buffers.
Possible values (comma separated list):
useopen If included, jump to the first open window that
contains the specified buffer (if there is one).
Otherwise: Do not examine other windows.
This setting is checked with |quickfix| commands, when
jumping to errors (":cc", ":cn", "cp", etc.). It is
also used in all buffer related split commands, for
example ":sbuffer", ":sbnext", or ":sbrewind".
split If included, split the current window before loading
a buffer. Otherwise: do not split, use current window.
Supported in |quickfix| commands that display errors.
*'syntax'* *'syn'*
'syntax' 'syn' string (default emtpy)
local to buffer
{not available when compiled without the |+syntax|
feature}
When this option is set, the syntax with this name is loaded, unless
syntax highlighting has been switched off with ":syntax off".
Otherwise this option does not always reflect the current syntax (the
b:current_syntax variable does).
This option is most useful in a modeline, for a file which syntax is
not automatically recognized. Example, for in an IDL file: >
/* vim: set syntax=idl : */
< To switch off syntax highlighting for the current file, use: >
:set syntax=OFF
< To switch syntax highlighting on according to the current value of the
'filetype' option: >
:set syntax=ON
< What actually happens when setting the 'syntax' option is that the
Syntax autocommand event is triggered with the value as argument.
This option is not copied to another buffer, independent of the 's' or
'S' flag in 'cpoptions'.
*'tabstop'* *'ts'*
'tabstop' 'ts' number (default 8)
local to buffer
Number of spaces that a <Tab> in the file counts for. Also see
|:retab| command, and 'softtabstop' option.
Note: Setting 'tabstop' to any other value than 8 can make your file
appear wrong in many places (e.g., when printing it).
There are four main ways to use tabs in Vim:
1. Always keep 'tabstop' at 8, set 'softtabstop' and 'shiftwidth' to 4
(or 3 or whatever you prefer) and use 'noexpandtab'. Then Vim
will use a mix of tabs and spaces, but typing Tab and BS will
behave like a tab appears every 4 (or 3) characters.
2. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use
'expandtab'. This way you will always insert spaces. The
formatting will never be messed up when 'tabstop' is changed.
3. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use a
|modeline| to set these values when editing the file again. Only
works when using Vim to edit the file.
4. Always set 'tabstop' and 'shiftwidth' to the same value, and
'noexpandtab'. This should then work (for initial indents only)
for any tabstop setting that people use. It might be nice to have
tabs after the first non-blank inserted as spaces if you do this
though. Otherwise aligned comments will be wrong when 'tabstop' is
changed.
*'tagbsearch'* *'tbs'* *'notagbsearch'* *'notbs'*
'tagbsearch' 'tbs' boolean (default on)
global
When searching for a tag (e.g., for the |:ta| command), Vim can either
use a binary search or a linear search in a tags file. Binary
searching makes searching for a tag a LOT faster, but a linear search
will find more tags if the tags file wasn't properly sorted.
Vim normally assumes that your tags files are sorted, or indicate that
they are not sorted. Only when this is not the case does the
'tagbsearch' option need to be switched off.
When 'tagbsearch' is on, binary searching is first used in the tags
files. In certain situations, Vim will do a linear search instead for
certain files, or retry all files with a linear search. When
'tagbsearch' is off, only a linear search is done.
Linear searching is done anyway, for one file, when Vim finds a line
at the start of the file indicating that it's not sorted: >
!_TAG_FILE_SORTED 0 /some command/
< [The whitespace before and after the '0' must be a single <Tab>]
When a binary search was done and no match was found in any of the
files listed in 'tags', and 'ignorecase' is set or a pattern is used
instead of a normal tag name, a retry is done with a linear search.
Tags in unsorted tags files, and matches with different case will only
be found in the retry.
If a tag file indicates that is is case-fold sorted, the second,
linear search can be avoided for the 'ignorecase' case. Use a value
of '2' in the "!_TAG_FILE_SORTED" line for this. A tag file can be
case-fold sorted with the -f switch to "sort" in most unices, as in
the command: "sort -f -o tags tags". For "excuberant ctags" version
5.3 or higher the -f or --fold-case-sort switch can be used for this
as well. Note that case must be folded to uppercase for this to work.
When 'tagbsearch' is off, tags searching is slower when a full match
exists, but faster when no full match exists. Tags in unsorted tags
files may only be found with 'tagbsearch' off.
When the tags file is not sorted, or sorted in a wrong way (not on
ASCII byte value), 'tagbsearch' should be off, or the line given above
must be included in the tags file.
This option doesn't affect commands that find all matching tags (e.g.,
command-line completion and ":help").
{Vi: always uses binary search in some versions}
*'taglength'* *'tl'*
'taglength' 'tl' number (default 0)
global
If non-zero, tags are significant up to this number of characters.
*'tagrelative'* *'tr'* *'notagrelative'* *'notr'*
'tagrelative' 'tr' boolean (Vim default: on, Vi default: off)
global
If on and using a tag file in another directory, file names in that
tag file are relative to the directory where the tag file is.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'tags'* *'tag'* *E433*
'tags' 'tag' string (default "./tags,tags", when compiled with
|+emacs_tags|: "./tags,./TAGS,tags,TAGS")
global or local to buffer |global-local|
Filenames for the tag command, separated by spaces or commas. To
include a space or comma in a file name, precede it with a backslash
(see |option-backslash| about including spaces and backslashes).
When a file name starts with "./", the '.' is replaced with the path
of the current file. But only when the 'd' flag is not included in
'cpoptions'. Environment variables are expanded |:set_env|. Also see
|tags-option|.
"*", "**" and other wildcards can be used to search for tags files in
a directory tree. See |file-searching|. {not available when compiled
without the |+path_extra| feature}
If Vim was compiled with the |+emacs_tags| feature, Emacs-style tag
files are also supported. They are automatically recognized. The
default value becomes "./tags,./TAGS,tags,TAGS", unless case
differences are ignored (MS-Windows). |emacs-tags|
The use of |:set+=| and |:set-=| is preferred when adding or removing
file names from the list. This avoids problems when a future version
uses another default.
{Vi: default is "tags /usr/lib/tags"}
*'tagstack'* *'tgst'* *'notagstack'* *'notgst'*
'tagstack' 'tgst' boolean (default on)
global
{not in all versions of Vi}
When on, the |tagstack| is used normally. When off, a ":tag" or
":tselect" command with an argument will not push the tag onto the
tagstack. A following ":tag" without an argument, a ":pop" command or
any other command that uses the tagstack will use the unmodified
tagstack, but does change the pointer to the active entry.
Resetting this option is useful when using a ":tag" command in a
mapping which should not change the tagstack.
*'term'* *E529* *E530* *E531*
'term' string (default is $TERM, if that fails:
in the GUI: "builtin_gui"
on Amiga: "amiga"
on BeOS: "beos-ansi"
on Mac: "mac-ansi"
on MiNT: "vt52"
on MS-DOS: "pcterm"
on OS/2: "os2ansi"
on Unix: "ansi"
on VMS: "ansi"
on Win 32: "win32")
global
Name of the terminal. Used for choosing the terminal control
characters. Environment variables are expanded |:set_env|.
For example: >
:set term=$TERM
< See |termcap|.
*'termbidi'* *'tbidi'*
*'notermbidi'* *'notbidi'*
'termbidi' 'tbidi' boolean (default off, on for "mlterm")
global
{only available when compiled with the |+arabic|
feature}
The terminal is in charge of Bi-directionality of text (as specified
by Unicode). The terminal is also expected to do the required shaping
that some languages (such as Arabic) require.
Setting this option implies that 'rightleft' will not be set when
'arabic' is set and the value of 'arabicshape' will be ignored.
Note that setting 'termbidi' has the immediate effect that
'arabicshape' is ignored, but 'rightleft' isn't changed automatically.
This option is reset when the GUI is started.
For further details see |arabic.txt|.
*'termencoding'* *'tenc'*
'termencoding' 'tenc' string (default "")
global
{only available when compiled with the |+multi_byte|
feature}
Encoding used for the terminal. This specifies what character
encoding the keyboard produces and the display will understand. For
the GUI it only applies to the keyboard ('encoding' is used for the
display).
*E617*
Note: This does not apply to the GTK+ 2 GUI. After the GUI has been
successfully initialized, 'termencoding' is forcibly set to "utf-8".
Any attempts to set a different value will be rejected, and an error
message is shown.
When empty, the same encoding is used as for the 'encoding' option.
This is the normal value.
Not all combinations for 'termencoding' and 'encoding' are valid. See
|encoding-table|.
The value for this option must be supported by iconv(). When iconv()
cannot handle the value, no conversion will be done and you will
probably experience problems with non-ASCII characters.
Example: You are working with the locale set to euc-jp (Japanese) and
want to edit a UTF-8 file: >
:let &termencoding = &encoding
:set encoding=utf-8
< You need to do this when your system has no locale support for UTF-8.
*'terse'* *'noterse'*
'terse' boolean (default off)
global
When set: Add 's' flag to 'shortmess' option (this makes the message
for a search that hits the start or end of the file not being
displayed). When reset: Remove 's' flag from 'shortmess' option. {Vi
shortens a lot of messages}
*'textauto'* *'ta'* *'notextauto'* *'nota'*
'textauto' 'ta' boolean (Vim default: on, Vi default: off)
global
This option is obsolete. Use 'fileformats'.
For backwards compatibility, when 'textauto' is set, 'fileformats' is
set to the default value for the current system. When 'textauto' is
reset, 'fileformats' is made empty.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'textmode'* *'tx'* *'notextmode'* *'notx'*
'textmode' 'tx' boolean (MS-DOS, Win32 and OS/2: default on,
others: default off)
local to buffer
This option is obsolete. Use 'fileformat'.
For backwards compatibility, when 'textmode' is set, 'fileformat' is
set to "dos". When 'textmode' is reset, 'fileformat' is set to
"unix".
*'textwidth'* *'tw'*
'textwidth' 'tw' number (default 0)
local to buffer
Maximum width of text that is being inserted. A longer line will be
broken after white space to get this width. A zero value disables
this. 'textwidth' is set to 0 when the 'paste' option is set. When
'textwidth' is zero, 'wrapmargin' may be used. See also
'formatoptions' and |ins-textwidth|.
NOTE: This option is set to 0 when 'compatible' is set.
*'thesaurus'* *'tsr'*
'thesaurus' 'tsr' string (default "")
global or local to buffer |global-local|
List of file names, separated by commas, that are used to lookup words
for thesesaurus completion commands |i_CTRL-X_CTRL-T|. Each line in
the file should contain words with similar meaning, separated by
non-keyword characters (white space is preferred). Maximum line
length is 510 bytes.
To obtain a file to be used here, check out the wordlist FAQ at
http://www.hyphenologist.co.uk .
To include a comma in a file name precede it with a backslash. Spaces
after a comma are ignored, otherwise spaces are included in the file
name. See |option-backslash| about using backslashes.
The use of |:set+=| and |:set-=| is preferred when adding or removing
directories from the list. This avoids problems when a future version
uses another default.
Backticks cannot be used in this option for security reasons.
*'tildeop'* *'top'* *'notildeop'* *'notop'*
'tildeop' 'top' boolean (default off)
global
When on: The tilde command "~" behaves like an operator.
NOTE: This option is reset when 'compatible' is set.
*'timeout'* *'to'* *'notimeout'* *'noto'*
'timeout' 'to' boolean (default on)
global
*'ttimeout'* *'nottimeout'*
'ttimeout' boolean (default off)
global
These two options together determine the behavior when part of a
mapped key sequence or keyboard code has been received:
'timeout' 'ttimeout' action ~
off off do not time out
on on or off time out on :mappings and key codes
off on time out on key codes
If both options are off, Vim will wait until either the complete
mapping or key sequence has been received, or it is clear that there
is no mapping or key sequence for the received characters. For
example: if you have mapped "vl" and Vim has received 'v', the next
character is needed to see if the 'v' is followed by an 'l'.
When one of the options is on, Vim will wait for about 1 second for
the next character to arrive. After that the already received
characters are interpreted as single characters. The waiting time can
be changed with the 'timeoutlen' option.
On slow terminals or very busy systems timing out may cause
malfunctioning cursor keys. If both options are off, Vim waits
forever after an entered <Esc> if there are key codes that start
with <Esc>. You will have to type <Esc> twice. If you do not have
problems with key codes, but would like to have :mapped key
sequences not timing out in 1 second, set the 'ttimeout' option and
reset the 'timeout' option.
NOTE: 'ttimeout' is reset when 'compatible' is set.
*'timeoutlen'* *'tm'*
'timeoutlen' 'tm' number (default 1000)
global
{not in all versions of Vi}
*'ttimeoutlen'* *'ttm'*
'ttimeoutlen' 'ttm' number (default -1)
global
The time in milliseconds that is waited for a key code or mapped key
sequence to complete. Normally only 'timeoutlen' is used and
'ttimeoutlen' is -1. When a different timeout value for key codes is
desired set 'ttimeoutlen' to a non-negative number.
ttimeoutlen mapping delay key code delay ~
< 0 'timeoutlen' 'timeoutlen'
>= 0 'timeoutlen' 'ttimeoutlen'
The timeout only happens when the 'timeout' and 'ttimeout' options
tell so. A useful setting would be
:set timeout timeoutlen=3000 ttimeoutlen=100
(time out on mapping after three seconds, time out on key codes after
a tenth of a second).
*'title'* *'notitle'*
'title' boolean (default off, on when title can be restored)
global
{not available when compiled without the |+title|
feature}
When on, the title of the window will be set to the value of
'titlestring' (if it is not empty), or to:
filename [+=-] (path) - VIM
Where:
filename the name of the file being edited
- indicates the file canot be modified, 'ma' off
+ indicates the file was modified
= indicates the file is read-only
=+ indicates the file is read-only and modified
(path) is the path of the file being edited
- VIM the server name |v:servername| or "VIM"
Only works if the terminal supports setting window titles
(currently Amiga console, Win32 console, all GUI versions and
terminals with a non- empty 't_ts' option - these are Unix xterm and
iris-ansi by default, where 't_ts' is taken from the builtin termcap).
*X11*
When Vim was compiled with HAVE_X11 defined, the original title will
be restored if possible. The output of ":version" will include "+X11"
when HAVE_X11 was defined, otherwise it will be "-X11". This also
works for the icon name |'icon'|.
But: When Vim was started with the |-X| argument, restoring the title
will not work (except in the GUI).
If the title cannot be restored, it is set to the value of 'titleold'.
You might want to restore the title outside of Vim then.
When using an xterm from a remote machine you can use this command:
rsh machine_name xterm -display $DISPLAY &
then the WINDOWID environment variable should be inherited and the
title of the window should change back to what it should be after
exiting Vim.
*'titlelen'*
'titlelen' number (default 85)
global
{not available when compiled without the |+title|
feature}
Gives the percentage of 'columns' to use for the length of the window
title. When the title is longer, only the end of the path name is
shown. A '<' character before the path name is used to indicate this.
Using a percentage makes this adapt to the width of the window. But
it won't work perfectly, because the actual number of characters
available also depends on the font used and other things in the title
bar. When 'titlelen' is zero the full path is used. Otherwise,
values from 1 to 30000 percent can be used.
'titlelen' is also used for the 'titlestring' option.
*'titleold'*
'titleold' string (default "Thanks for flying Vim")
global
{only available when compiled with the |+title|
feature}
This option will be used for the window title when exiting Vim if the
original title cannot be restored. Only happens if 'title' is on or
'titlestring' is not empty.
*'titlestring'*
'titlestring' string (default "")
global
{not available when compiled without the |+title|
feature}
When this option is not empty, it will be used for the title of the
window. This happens only when the 'title' option is on.
Only works if the terminal supports setting window titles (currently
Amiga console, Win32 console, all GUI versions and terminals with a
non-empty 't_ts' option).
When Vim was compiled with HAVE_X11 defined, the original title will
be restored if possible |X11|.
When this option contains printf-style '%' items, they will be
expanded according to the rules used for 'statusline'.
Example: >
:auto BufEnter * let &titlestring = hostname() . "/" . expand("%:p")
:set title titlestring=%<%F%=%l/%L-%P titlelen=70
< The value of 'titlelen' is used to align items in the middle or right
of the available space.
Some people prefer to have the file name first: >
:set titlestring=%t%(\ %M%)%(\ (%{expand(\"%:~:.:h\")})%)%(\ %a%)
< Note the use of "%{ }" and an expression to get the path of the file,
without the file name. The "%( %)" constructs are used to add a
separating space only when needed.
NOTE: Use of special characters in 'titlestring' may cause the display
to be garbled (e.g., when it contains a CR or NL character).
{not available when compiled without the |+statusline| feature}
*'toolbar'* *'tb'*
'toolbar' 'tb' string (default "icons,tooltips")
global
{only for |+GUI_GTK|, |+GUI_Athena|, |+GUI_Motif| and
|+GUI_Photon|}
The contents of this option controls various toolbar settings. The
possible values are:
icons Toolbar buttons are shown with icons.
text Toolbar buttons shown with text.
horiz Icon and text of a toolbar button are
horizontally arranged. {only in GTK+ 2 GUI}
tooltips Tooltips are active for toolbar buttons.
Tooltips refer to the popup help text which appears after the mouse
cursor is placed over a toolbar button for a brief moment.
If you want the toolbar to be shown with icons as well as text, do the
following: >
:set tb=icons,text
< Motif and Athena cannot display icons and text at the same time. They
will show icons if both are requested.
If none of the strings specified in 'toolbar' are valid or if
'toolbar' is empty, this option is ignored. If you want to disable
the toolbar, you need to set the 'guioptions' option. For example: >
:set guioptions-=T
< Also see |gui-toolbar|.
*'toolbariconsize'* *'tbis'*
'toolbariconsize' 'tbis' string (default "small")
global
{only in the GTK+ 2 GUI}
Controls the size of toolbar icons. The possible values are:
tiny Use tiny toolbar icons.
small Use small toolbar icons (default).
medium Use medium-sized toolbar icons.
large Use large toolbar icons.
The exact dimensions in pixels of the various icon sizes depend on
the current theme. Common dimensions are large=32x32, medium=24x24,
small=20x20 and tiny=16x16.
If 'toolbariconsize' is empty, the global default size as determined
by user preferences or the current theme is used.
*'ttybuiltin'* *'tbi'* *'nottybuiltin'* *'notbi'*
'ttybuiltin' 'tbi' boolean (default on)
global
When on, the builtin termcaps are searched before the external ones.
When off the builtin termcaps are searched after the external ones.
When this option is changed, you should set the 'term' option next for
the change to take effect, for example: >
:set notbi term=$TERM
< See also |termcap|.
Rationale: The default for this option is "on", because the builtin
termcap entries are generally better (many systems contain faulty
xterm entries...).
*'ttyfast'* *'tf'* *'nottyfast'* *'notf'*
'ttyfast' 'tf' boolean (default off, on when 'term' is xterm, hpterm,
sun-cmd, screen, rxvt, dtterm or
iris-ansi; also on when running Vim in
a DOS console)
global
Indicates a fast terminal connection. More characters will be sent to
the screen for redrawing, instead of using insert/delete line
commands. Improves smoothness of redrawing when there are multiple
windows and the terminal does not support a scrolling region.
Also enables the extra writing of characters at the end of each screen
line for lines that wrap. This helps when using copy/paste with the
mouse in an xterm and other terminals.
*'ttymouse'* *'ttym'*
'ttymouse' 'ttym' string (default depends on 'term')
global
{only in Unix and VMS, doesn't work in the GUI; not
available when compiled without |+mouse|}
Name of the terminal type for which mouse codes are to be recognized.
Currently these three strings are valid:
*xterm-mouse*
xterm xterm-like mouse handling. The mouse generates
"<Esc>[Mscr", where "scr" is three bytes:
"s" = button state
"c" = column plus 33
"r" = row plus 33
xterm2 Works like "xterm", but with the xterm reporting the
mouse position while the mouse is dragged. This works
much faster and more precise. Your xterm must at
least at patchlevel 88 / XFree 3.3.3 for this to
work. See below for how Vim detects this
automatically.
*netterm-mouse*
netterm NetTerm mouse handling. The mouse generates
"<Esc>}r,c<CR>", where "r,c" are two decimal numbers
for the row and column.
*dec-mouse*
dec DEC terminal mouse handling. The mouse generates a
rather complex sequence, starting with "<Esc>[".
*jsbterm-mouse*
jsbterm JSB term mouse handling.
*pterm-mouse*
pterm QNX pterm mouse handling.
The mouse handling must be enabled at compile time |+mouse_xterm|
|+mouse_dec| |+mouse_netterm|.
Only "xterm"(2) is really recognized. NetTerm mouse codes are always
recognized, if enabled at compile time. DEC terminal mouse codes
are recognized if enabled at compile time, and 'ttymouse' is not
"xterm" (because the xterm and dec mouse codes conflict).
This option is automatically set to "xterm", when the 'term' option is
set to a name that starts with "xterm", and 'ttymouse' is not "xterm"
or "xterm2" already. The main use of this option is to set it to
"xterm", when the terminal name doesn't start with "xterm", but it can
handle xterm mouse codes.
The "xterm2" value will be set if the xterm version is reported to be
95 of higher. This only works when compiled with the |+termresponse|
feature and if |t_RV| is set to the escape sequence to request the
xterm version number. Otherwise "xterm2" must be set explicitly.
If you do not want 'ttymouse' to be set to "xterm2" automatically, set
t_RV to an empty string: >
:set t_RV=
<
*'ttyscroll'* *'tsl'*
'ttyscroll' 'tsl' number (default 999)
global
Maximum number of lines to scroll the screen. If there are more lines
to scroll the window is redrawn. For terminals where scrolling is
very slow and redrawing is not slow this can be set to a small number,
e.g., 3, to speed up displaying.
*'ttytype'* *'tty'*
'ttytype' 'tty' string (default from $TERM)
global
Alias for 'term', see above.
-->
*'undolevels'* *'ul'*
'undolevels' 'ul' number (default 100, 1000 for Unix, VMS,
Win32 and OS/2)
global
Maximum number of changes that can be undone. Since undo information
is kept in memory, higher numbers will cause more memory to be used
(nevertheless, a single change can use an unlimited amount of memory).
Set to 0 for Vi compatibility: One level of undo and "u" undoes
itself: >
set ul=0
<!--
< But you can also get Vi compatibility by including the 'u' flag in
'cpoptions', and still be able to use CTRL-R to repeat undo.
Set to a negative number for no undo at all: >
set ul=-1
< This helps when you run out of memory for a single change.
Also see |undo-two-ways|.
-->
<!--
*'updatecount'* *'uc'*
'updatecount' 'uc' number (default: 200)
global
After typing this many characters the swap file will be written to
disk. When zero, no swap file will be created at all (see chapter on
recovery |crash-recovery|). 'updatecount' is set to zero by starting
Vim with the "-n" option, see |startup|. When editing in readonly
mode this option will be initialized to 10000.
The swapfile can be disabled per buffer with |'swapfile'|.
When 'updatecount' is set from non-zero to zero, swap files are
created for all buffers that have 'swapfile' set. When 'updatecount'
is set to zero, existing swap files are not deleted.
Also see |'swapsync'|.
This option has no meaning in buffers where |'buftype'| is "nofile"
or "nowrite".
*'updatetime'* *'ut'*
'updatetime' 'ut' number (default 4000)
global
If this many milliseconds nothing is typed the swap file will be
written to disk (see |crash-recovery|). Also used for the
|CursorHold| autocommand event.
*'verbose'* *'vbs'*
'verbose' 'vbs' number (default 0)
global
When bigger than zero, Vim will give messages about what it is doing.
Currently, these messages are given:
>= 1 When the viminfo file is read or written.
>= 2 When a file is ":source"'ed.
>= 5 Every searched tags file.
>= 8 Files for which a group of autocommands is executed.
>= 9 Every executed autocommand.
>= 12 Every executed function.
>= 13 When an exception is thrown, caught, finished, or discarded.
>= 14 Anything pending in a ":finally" clause.
>= 15 Every executed Ex command (truncated at 200 characters).
This option can also be set with the "-V" argument. See |-V|.
This option is also set by the |:verbose| command.
*'viewdir'* *'vdir'*
'viewdir' 'vdir' string (default for Amiga, MS-DOS, OS/2 and Win32:
"$VIM/vimfiles/view",
for Unix: "~/.vim/view",
for Macintosh: "$VIM:vimfiles:view"
for VMS: "sys$login:vimfiles/view"
for RiscOS: "Choices:vimfiles/view")
global
{not available when compiled without the +mksession
feature}
Name of the directory where to store files for |:mkview|.
This option cannot be set from a |modeline|, for security reasons.
*'viewoptions'* *'vop'*
'viewoptions' 'vop' string (default: "folds,options,cursor")
global
{not available when compiled without the +mksession
feature}
Changes the effect of the |:mkview| command. It is a comma separated
list of words. Each word enables saving and restoring something:
word save and restore ~
cursor cursor position in file and in window
folds manually created folds, opened/closed folds and local
fold options
options options and mappings local to a window or buffer (not
global values for local options)
slash backslashes in file names replaced with forward
slashes
unix with Unix end-of-line format (single <NL>), even when
on Windows or DOS
"slash" and "unix" are useful on Windows when sharing view files
with Unix. The Unix version of Vim cannot source dos format scripts,
but the Windows version of Vim can source unix format scripts.
*'viminfo'* *'vi'* *E526* *E527* *E528*
'viminfo' 'vi' string (Vi default: "", Vim default for MS-DOS,
Windows and OS/2: '20,"50,h,rA:,rB:,
for Amiga: '20,"50,h,rdf0:,rdf1:,rdf2:
for others: '20,"50,h)
global
{not available when compiled without the |+viminfo|
feature}
When non-empty, the viminfo file is read upon startup and written
when exiting Vim (see |viminfo-file|). The string should be a comma
separated list of parameters, each consisting of a single character
identifying the particular parameter, followed by a number or string
which specifies the value of that parameter. If a particular
character is left out, then the default value is used for that
parameter. The following is a list of the identifying characters and
the effect of their value.
CHAR VALUE ~
! When included, save and restore global variables that start
with an uppercase letter, and don't contain a lowercase
letter. Thus "KEEPTHIS and "K_L_M" are stored, but "KeepThis"
and "_K_L_M" are not.
" Maximum number of lines saved for each register. If zero then
registers are not saved. When not included, all lines are
saved. Dont forget to put a backslash before the ", otherwise
it will be recognized as the start of a comment!
% When included, save and restore the buffer list. If Vim is
started with a file name argument, the buffer list is not
restored. If Vim is started without a file name argument, the
buffer list is restored from the viminfo file. Buffers
without a file name and buffers for help files are not written
to the viminfo file.
' Maximum number of previously edited files for which the marks
are remembered. This parameter must always be included when
'viminfo' is non-empty.
Including this item also means that the |jumplist| is stored
in the viminfo file.
/ Maximum number of items in the search pattern history to be
saved. If non-zero, then the previous search and substitute
patterns are also saved. When not included, the value of
'history' is used.
: Maximum number of items in the command-line history to be
saved. When not included, the value of 'history' is used.
@ Maximum number of items in the input-line history to be
saved. When not included, the value of 'history' is used.
c When included, convert the text in the viminfo file from the
'encoding' used when writing the file to the current
'encoding'. See |viminfo-encoding|.
f Whether file marks need to be stored. If zero, file marks ('0
to '9, 'A to 'Z) are not stored. When not present or when
non-zero, they are all stored. '0 is used for the current
cursor position (when exiting or when doing ":wviminfo").
h Disable the effect of 'hlsearch' when loading the viminfo
file. When not included, it depends on whether ":nohlsearch"
has been used since the last search command.
n Name of the viminfo file. The name must immediately follow
the 'n'. Must be the last one! If the "-i" argument was
given when starting Vim, that file name overrides the one
given here with 'viminfo'. Environment variables are expanded
when opening the file, not when setting the option.
r Removable media. The argument is a string (up to the next
','). This parameter can be given several times. Each
specifies the start of a path for which no marks will be
stored. This is to avoid removable media. For MS-DOS you
could use "ra:,rb:", for Amiga "rdf0:,rdf1:,rdf2:". Case is
ignored. Maximum length of each 'r' argument is 50
characters.
Example: >
:set viminfo='50,\"1000,:0,n~/vim/viminfo
<
'50 Marks will be remembered for the last 50 files you
edited.
"1000 Contents of registers (up to 1000 lines each) will be
remembered.
:0 Command-line history will not be saved.
n~/vim/viminfo The name of the file to use is "~/vim/viminfo".
no / Since '/' is not specified, the default will be used,
that is, save all of the search history, and also the
previous search and substitute patterns.
no % The buffer list will not be saved nor read back.
no h 'hlsearch' highlighting will be restored.
This option cannot be set from a |modeline|, for security reasons.
*'virtualedit'* *'ve'*
'virtualedit' 've' string (default "")
global
{not available when compiled without the
|+virtualedit| feature}
A comma separated list of these words:
block Allow virtual editing in Visual block mode.
insert Allow virtual editing in Insert mode.
all Allow virtual editing in all modes.
Virtual editing means that the cursor can be positioned where there is
no actual character. This can be halfway into a Tab or beyond the end
of the line. Useful for selecting a rectangle in Visual mode and
editing a table.
-->
*'visualbell'* *'vb'* *'novisualbell'* *'novb'* *beep*
'visualbell' 'vb' boolean (default off)
global
Use visual bell instead of beeping.
<!--
The terminal code to display the
visual bell is given with 't_vb'. When no beep or flash is wanted,
use ":set vb t_vb=".
Note: When the GUI starts, 't_vb' is reset to its default value. You
might want to set it again in your |gvimrc|.
In the GUI, 't_vb' defaults to "<Esc>|f", which inverts the display
for 20 msec. If you want to use a different time, use "<Esc>|40f",
where 40 is the time in msec.
Also see 'errorbells'.
-->
<!--
*'warn'* *'nowarn'*
'warn' boolean (default on)
global
Give a warning message when a shell command is used while the buffer
has been changed.
*'weirdinvert'* *'wiv'* *'noweirdinvert'* *'nowiv'*
'weirdinvert' 'wiv' boolean (default off)
global
This option has the same effect as the 't_xs' termcap option.
It is provided for backwards compatibility with version 4.x.
Setting 'weirdinvert' has the effect of making 't_xs' non-empty, and
vice versa. Has no effect when the GUI is running.
*'whichwrap'* *'ww'*
'whichwrap' 'ww' string (Vim default: "b,s", Vi default: "")
global
Allow specified keys that move the cursor left/right to wrap to the
previous/next line when the cursor is on the first/last character in
the line. Concatenate characters to allow this for these keys:
char key mode ~
b <BS> Normal and Visual
s <Space> Normal and Visual
h "h" Normal and Visual
l "l" Normal and Visual
< <Left> Normal and Visual
> <Right> Normal and Visual
~ "~" Normal
[ <Left> Insert and Replace
] <Right> Insert and Replace
For example: >
:set ww=<,>,[,]
< allows wrap only when cursor keys are used.
When the movement keys are used in combination with a delete or change
operator, the <EOL> also counts for a character. This makes "3h"
different from "3dh" when the cursor crosses the end of a line. This
is also true for "x" and "X", because they do the same as "dl" and
"dh". If you use this, you may also want to use the mapping
":map <BS> X" to make backspace delete the character in front of the
cursor.
When 'l' is included, you get a side effect: "yl" on an empty line
will include the <EOL>, so that "p" will insert a new line.
NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'wildchar'* *'wc'*
'wildchar' 'wc' number (Vim default: <Tab>, Vi default: CTRL-E)
global
Character you have to type to start wildcard expansion in the
command-line, as specified with 'wildmode'.
The character is not recognized when used inside a macro. See
'wildcharm' for that.
Although 'wc' is a number option, you can set it to a special key: >
:set wc=<Esc>
< NOTE: This option is set to the Vi default value when 'compatible' is
set and to the Vim default value when 'compatible' is reset.
*'wildcharm'* *'wcm'*
'wildcharm' 'wcm' number (default: none (0))
global
'wildcharm' works exactly like 'wildchar', except that it is
recognized when used inside a macro. You can find "spare" command-line
keys suitable for this option by looking at |ex-edit-index|. Normally
you'll never actually type 'wildcharm', just use it in mappings that
automatically invoke completion mode, e.g.: >
:set wcm=<C-Z>
:cmap ss so $vim/sessions/*.vim<C-Z>
< Then after typing :ss you can use CTRL-P & CTRL-N.
*'wildignore'* *'wig'*
'wildignore' 'wig' string (default "")
global
{not available when compiled without the |+wildignore|
feature}
A list of file patterns. A file that matches with one of these
patterns is ignored when completing file or directory names.
The pattern is used like with |:autocmd|, see |autocmd-patterns|.
Also see 'suffixes'.
Example: >
:set wildignore=*.o,*.obj
< The use of |:set+=| and |:set-=| is preferred when adding or removing
a pattern from the list. This avoids problems when a future version
uses another default.
*'wildmenu'* *'wmnu'* *'nowildmenu'* *'nowmnu'*
'wildmenu' 'wmnu' boolean (default off)
global
{not available if compiled without the |+wildmenu|
feature}
When 'wildmenu' is on, command-line completion operates in an enhanced
mode. On pressing 'wildchar' (usually <Tab>) to invoke completion,
the possible matches are shown just above the command line, with the
first match highlighted (overwriting the status line, if there is
one). Keys that show the previous/next match, such as <Tab> or
CTRL-P/CTRL-N, cause the highlight to move to the appropriate match.
When 'wildmode' is used, "wildmenu" mode is used where "full" is
specified. "longest" and "list" do not start "wildmenu" mode.
If there are more matches than can fit in the line, a ">" is shown on
the right and/or a "<" is shown on the left. The status line scrolls
as needed.
The "wildmenu" mode is abandoned when a key is hit that is not used
for selecting a completion.
While the "wildmenu" is active the following keys have special
meanings:
<Left> <Right> - select previous/next match (like CTRL-P/CTRL-N)
<Down> - in filename/menu name completion: move into a
subdirectory or submenu.
<CR> - in menu completion, when the cursor is just after a
dot: move into a submenu.
<Up> - in filename/menu name completion: move up into
parent directory or parent menu.
This makes the menus accessible from the console |console-menus|.
If you prefer the <Left> and <Right> keys to move the cursor instead
of selecting a different match, use this: >
:cnoremap <Left> <Space><BS><Left>
:cnoremap <Right> <Space><BS><Right>
<
The "WildMenu" highlighting is used for displaying the current match
|hl-WildMenu|.
*'wildmode'* *'wim'*
'wildmode' 'wim' string (Vim default: "full")
global
Completion mode that is used for the character specified with
'wildchar'. It is a comma separated list of up to four parts. Each
part specifies what to do for each consecutive use of 'wildchar. The
first part specifies the behavior for the first use of 'wildchar',
The second part for the second use, etc.
These are the possible values for each part:
"" Complete only the first match.
"full" Complete the next full match. After the last match,
the original string is used and then the first match
again.
"longest" Complete till longest common string. If this doesn't
result in a longer string, use the next part.
"longest:full" Like "longest", but also start 'wildmenu' if it is
enabled.
"list" When more than one match, list all matches.
"list:full" When more than one match, list all matches and
complete first match.
"list:longest" When more than one match, list all matches and
complete till longest common string.
When there is only a single match, it is fully completed in all cases.
Examples: >
:set wildmode=full
< Complete first full match, next match, etc. (the default) >
:set wildmode=longest,full
< Complete longest common string, then each full match >
:set wildmode=list:full
< List all matches and complete each full match >
:set wildmode=list,full
< List all matches without completing, then each full match >
:set wildmode=longest,list
< Complete longest common string, then list alternatives.
*'winaltkeys'* *'wak'*
'winaltkeys' 'wak' string (default "menu")
global
{only used in Win32, Motif, GTK and Photon GUI}
Some GUI versions allow the access to menu entries by using the ALT
key in combination with a character that appears underlined in the
menu. This conflicts with the use of the ALT key for mappings and
entering special characters. This option tells what to do:
no Don't use ALT keys for menus. ALT key combinations can be
mapped, but there is no automatic handling. This can then be
done with the |:simalt| command.
yes ALT key handling is done by the windowing system. ALT key
combinations cannot be mapped.
menu Using ALT in combination with a character that is a menu
shortcut key, will be handled by the windowing system. Other
keys can be mapped.
If the menu is disabled by excluding 'm' from 'guioptions', the ALT
key is never used for the menu.
In the Win32 version, the <F10> key is handled like this too, since
Windows uses it to select a menu.
*'winheight'* *'wh'* *E591*
'winheight' 'wh' number (default 1)
global
{not available when compiled without the +windows
feature}
Minimal number of lines for the current window. This is not a hard
minimum, Vim will use fewer lines if there is not enough room. If the
current window is smaller, its size is increased, at the cost of the
height of other windows. Set it to 999 to make the current window
always fill the screen. Set it to a small number for normal editing.
Minimum value is 1.
The height is not adjusted after one of the commands to change the
height of the current window.
'winheight' applies to the current window. Use 'winminheight' to set
the minimal height for other windows.
*'winfixheight'* *'wfh'*
'winfixheight' 'wfh' boolean (default off)
local to window
{not available when compiled without the +windows
feature}
Keep the window height when windows are opened or closed and
'equalalways' is set. Set by default for the |preview-window| and
|quickfix-window|.
The height may be changed anyway when running out of room.
*'winminheight'* *'wmh'*
'winminheight' 'wmh' number (default 1)
global
{not available when compiled without the +windows
feature}
The minimal height of a window, when it's not the current window.
This is a hard minimum, windows will never become smaller.
When set to zero, windows may be "squashed" to zero lines (i.e. just a
status bar) if necessary. They will return to at least one line when
they become active (since the cursor has to have somewhere to go.)
Use 'winheight' to set the minimal height of the current window.
This option is only checked when making a window smaller. Don't use a
large number, it will cause errors when opening more than a few
windows. A value of 0 to 3 is reasonable.
*'winminwidth'* *'wmw'*
'winminwidth' 'wmw' number (default 1)
global
{not available when compiled without the +vertsplit
feature}
The minimal width of a window, when it's not the current window.
This is a hard minimum, windows will never become smaller.
When set to zero, windows may be "squashed" to zero columns (i.e. just
a vertical separator) if necessary. They will return to at least one
line when they become active (since the cursor has to have somewhere
to go.)
Use 'winwidth' to set the minimal width of the current window.
This option is only checked when making a window smaller. Don't use a
large number, it will cause errors when opening more than a few
windows. A value of 0 to 12 is reasonable.
*'winwidth'* *'wiw'* *E592*
'winwidth' 'wiw' number (default 20)
global
{not available when compiled without the +vertsplit
feature}
Minimal number of columns for the current window. This is not a hard
minimum, Vim will use fewer columns if there is not enough room. If
the current window is smaller, its size is increased, at the cost of
the width of other windows. Set it to 999 to make the current window
always fill the screen. Set it to a small number for normal editing.
The width is not adjusted after one of the commands to change the
width of the current window.
'winwidth' applies to the current window. Use 'winminwidth' to set
the minimal width for other windows.
*'wrap'* *'nowrap'*
'wrap' boolean (default on)
local to window
This option changes how text is displayed. It doesn't change the text
in the buffer, see 'textwidth' for that.
When on, lines longer than the width of the window will wrap and
displaying continues on the next line. When off lines will not wrap
and only part of long lines will be displayed. When the cursor is
moved to a part that is not shown, the screen will scroll
horizontally.
The line will be broken in the middle of a word if necessary. See
'linebreak' to get the break at a word boundary.
To make scrolling horizontally a bit more useful, try this: >
:set sidescroll=5
:set listchars+=precedes:<,extends:>
< See 'sidescroll', 'listchars' and |wrap-off|.
*'wrapmargin'* *'wm'*
'wrapmargin' 'wm' number (default 0)
local to buffer
Number of characters from the right window border where wrapping
starts. When typing text beyond this limit, an <EOL> will be inserted
and inserting continues on the next line. When 'textwidth' is
non-zero, this option is not used. See also 'formatoptions' and
|ins-textwidth|. {Vi: works differently and less usefully}
-->
*'wrapscan'* *'ws'* *'nowrapscan'* *'nows'*
'wrapscan' 'ws' boolean (default on) *E384* *E385*
global
Searches wrap around the end of the file.
<!--
*'write'* *'nowrite'*
'write' boolean (default on)
global
Allows writing files. When not set, writing a file is not allowed.
Can be used for a view-only mode, where modifications to the text are
still allowed. Can be reset with the |-m| or |-M| command line
argument. Filtering text is still possible, even though this requires
writing a temporary file.
*'writeany'* *'wa'* *'nowriteany'* *'nowa'*
'writeany' 'wa' boolean (default off)
global
Allows writing to any file with no need for "!" override.
*'writebackup'* *'wb'* *'nowritebackup'* *'nowb'*
'writebackup' 'wb' boolean (default on with |+writebackup| feature, off
otherwise)
global
Make a backup before overwriting a file. The backup is removed after
the file was successfully written, unless the 'backup' option is
also on. Reset this option if your file system is almost full. See
|backup-table| for another explanation.
When the 'backupskip' pattern matches, a backup is not made anyway.
NOTE: This option is set to the default value when 'compatible' is
set.
*'writedelay'* *'wd'*
'writedelay' 'wd' number (default 0)
global
The number of microseconds to wait for each character sent to the
screen. When non-zero, characters are sent to the terminal one by
one. For MS-DOS pcterm this does not work. For debugging purposes.
