Options *options*
1. Setting options |set-option|
2. Automatically setting options |auto-setting|
3. Saving settings |save-settings|
4. 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:
toggle can only be on or off *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.
: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. {not in Vi}
:se[t] {option}& Reset option to its default value. {not in Vi}
:se[t] all& Set all options, except terminal options, to their
default value. The values of 'term', 'lines' and
'columns' are not changed {not in Vi}
:se[t] {option}={value} or
:se[t] {option}:{value}
Set string or number option to {value}. 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 <Tab> (or whatever the value of
'wildchar' is). See |cmdline-completion|.
See |option-backslash| for using backslashes in
{value}.
*: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) {not in Vi}
If your delete key terminal code is wrong, but the
code for backspace is allright, 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.
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
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 text up to the next space will be skipped. Thus following arguments
will be processed.
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
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|.
*: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,$HOME/include,.
*$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'.
*$VIM*
The environment variable "$VIM" is used to locate various support files, such
as the on-line documentation and files used for syntax highlighting. For
example, the main help file is normally "$VIM/doc/help.txt".
To avoid the need for every user to set the $VIM environment variable, Vim
will try to get the value for $VIM in this order:
1. The value defined by the $VIM environment variable. You can use this to
make Vim look in a specific directory for its support files. Example:
setenv VIM /home/paul/vim
2. For MSDOS and Win32 the environment variable $HOME is used, when defined.
Works just like setting the $VIM environment variable.
3. The path from 'helpfile' is used, unless it contains some environment
variable too (the default is "$VIM/doc/help.txt": chicken-egg problem).
The file name ("help.txt" or any other) is removed. If it then ends in
"/doc", this is removed too.
4. For MSDOS, Win32 and OS/2 Vim tries to use the directory name of the
executable. If it ends in "/src", this is removed. This is useful if you
unpacked the .zip file in some directory, and adjusted the search path to
find the vim executable.
5. For Unix the compile-time defined installation directory is used (see the
output of ":version").
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.
*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"
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.
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.
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*
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]set {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
set the string "set " (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:").
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 '\'. No other
commands than "set" are supported, for security reasons (somebody might create
a trojan horse text file with modelines).
3. Saving settings *save-settings*
*:mk* *:mkexrc*
:mk[exrc] [file] Write current key mappings and changed options to
[file] (default ".exrc" in the current directory),
unless it already exists. {not in Vi}
:mk[exrc]! [file] Always write current key mappings and changed
options to [file] (default ".exrc" in the current
directory). {not in Vi}
*:mkv* *:mkvimrc*
:mkv[imrc][!] [file] Like as :mkexrc, but default is ".vimrc" in the
current directory. The ":version" command is also
written to the file. {not in Vi}
These commands will write ":map" and ":set" commands to a file, in such a way
that when these commands are executed, the current key mappings and options
will be set to the same values. The options 'columns', 'endofline', 'lines',
'modified', 'scroll', 'term' and 'ttyfast' are not included, because these are
terminal or file dependent. Note that the options 'binary', 'fileformat',
'paste' and 'readonly' are included, this might not always be what you want.
A common method is to use a default ".vimrc" file, make some modifications
with ":map" and ":set" commands and write the modified file. First read the
default ".vimrc" in with a command like ":source ~piet/.vimrc.Cprogs", change
the settings and then save them in the current directory with ":mkvimrc!". If
you want to make this file your default .vimrc, move it to your home directory
(on Unix), s: (Amiga) or $VIM directory (MS-DOS). You could also use
autocommands |autocommand| and/or modelines |modeline|.
If you only want to add a single option setting to your vimrc, you can use
these steps:
1. Edit your vimrc file with Vim.
2. Play with the option until it's right. E.g., try out different values for
'guifont'.
3. Append a line to set the value of the option, using the expression register
'=' to enter the value. E.g., for the 'guifont' option:
o:set guifont=<C-R>=&guifont<CR><Esc>
[<C-R> is a CTRL-R, <CR> is a return, <Esc> is the escape key]
Note that when you create a .vimrc file, this can influence the 'compatible'
option, which has several side effects. See |'compatible'|.
4. 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 an option that can be toggled 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' in 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.
A jump table for the options with a short description can be found at |X_op|.
*'aleph'* *'al'*
'aleph' 'al' number (default 128 for MS-DOS, 224 otherwise)
global
{not in Vi}
{only available when compiled with the |+rightleft|
feature}
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 |rightleft.txt|.
*'altkeymap'* *'akm'* *'noalkeymap'* *'noakm'*
'altkeymap' 'akm' toggle (default off)
global
{not in Vi}
{only available when compiled with the |+farsi|
feature}
When on, the second language is Farsi. In editing mode CTRL-_ toggles
the keyboard map between Farsi and English.
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|.
*'autoindent'* *'ai'* *'noautoindent'* *'noai'*
'autoindent' 'ai' toggle (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> 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 specific
cases. 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}.
*'autowrite'* *'aw'* *'noautowrite'* *'noaw'*
'autowrite' 'aw' toggle (default off)
global
Write the contents of the file, if it has been modified, on each
:next, :rewind, :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.
*'background'* *'bg'*
'background' 'bg' string (default "dark" or "light")
global
{not in Vi}
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.
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").
For the Win32 GUI, setting 'background' before starting the GUI, will
change the background and foreground colors to lightgrey on black or
black on white. On other systems setting 'background' does not
change the foreground or background colors.
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 "$VIM/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' number (default 0)
global
{not in Vi}
Influences the working of <BS>, <Del>, CTRL-W and CTRL-U in Insert
mode:
value effect
0 Vi compatible backspacing is used.
1 allow backspacing over <EOL>s.
2 allow backspacing over the start of insert. CTRL-W and CTRL-U
stop once at the start of insert.
See |:fixdel| if your <BS> or <Del> key does not do what you want.
*'backup'* *'bk'* *'nobackup'* *'nobk'*
'backup' 'bk' toggle (default off)
global
{not in Vi}
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.
*'backupdir'* *'bdir'*
'backupdir' 'bdir' string (default for Amiga: ".,t:",
for MS-DOS and Win32: ".,c:/tmp,c:/temp"
for Unix: ".,~/tmp,~/")
global
{not in Vi}
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!).
- 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.
- 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.
*'backupext'* *'bex'*
'backupext' 'bex' string (default "~")
global
{not in Vi}
String which is appended to a file name to make the name of the
backup file. The default is quite unusual, because this avoids
accidently 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.
*'binary'* *'bin'* *'nobinary'* *'nobin'*
'binary' 'bin' toggle (default off)
local to buffer
{not in Vi}
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).
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' toggle (default on)
global
{not in Vi} {Only for MS-DOS}
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.
*'breakat'* *'brk'*
'breakat' 'brk' string (default " ^I!@*-+_;:,./?")
global
{not in Vi}
This option lets you choose which characters might cause a line
break if 'linebreak' is on.
*'cindent'* *'cin'* *'nocindent'* *'nocin'*
'cindent' 'cin' toggle (default off)
local to buffer
{not in Vi}
{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 'lisp' is not on and 'equalprg' is empty,
the "=" operator indents using this algorithm rather than calling an
external program. See |C-indenting|. This option is switched off
when 'paste' is set. When you don't like the way 'cindent' works, try
the 'smartindent' option.
'cinkeys' 'cink' string (default "0{,0},:,0#,!^F,o,O,e")
local to buffer
{not in Vi}
{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 'cindent' is on. See
|C-indenting|.
*'cinoptions'* *'cino'*
'cinoptions' 'cino' string (default "")
local to buffer
{not in Vi}
{not available when compiled without the |+cindent|
feature}
The 'cinoptions' affect the way 'cindent' reindents lines in a C
program. See |C-indenting|.
*'cinwords'* *'cinw'*
'cinwords' 'cinw' string (default "if,else,while,do,for,switch")
local to buffer
{not in Vi}
{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 {}).
*'cmdheight'* *'ch'*
'cmdheight' 'ch' number (default 1)
global
{not in Vi}
Number of lines to use for the command line. Helps avoiding
|hit-return| prompts.
*'columns'* *'co'*
'columns' 'co' number (default 80 or terminal width)
global
{not in Vi}
Number of columns of the screen. Normally this is set by the terminal
initialization and does not have to be set by hand.
*'comments'* *'com'*
'comments' 'com' string (default
"sr:/*,mb:*,el:*/,://,b:#,:%,:XCOMM,n:>,fb:-")
local to buffer
{not in Vi}
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.
*'compatible'* *'cp'* *'nocompatible'* *'nocp'*
'compatible' 'cp' toggle (default on, off when a .vimrc file is found)
global
{not in Vi}
This option has the function of making Vim either more Vi-compatible,
or 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.
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. 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.
See also 'cpoptions'.
option + set value effect
'backspace' 0 normal backspace
'backup' off no backup file
'cindent' off no C code indentation
'cpoptions' + (all flags) Vi-compatible flags
'digraph' off no digraphs
'esckeys' + off no <Esc>-keys in Insert mode
'expandtab' off tabs not expanded to spaces
'fileformats' + "" no automatic file format detection,
"dos,unix" except for DOS, Windows and OS/2
'formatoptions' + "vt" Vi compatible formatting
'gdefault' off no default 'g' flag for ":s"
'history' + 0 no commandline history
'hlsearch' off no highlighting of search matches
'incsearch' off no incremental searching
'insertmode' off do not start in Insert mode
'iskeyword' + "@,48-57,_" keywords contain alphanumeric
characters and '_'
'joinspaces' on insert 2 spaces after period
'modeline' + off no modelines
'more' + off no pauses in listings
'revins' off no reverse insert
'ruler' off no ruler
'scrolljump' 1 no jump scroll
'scrolloff' 0 no scroll offset
'shiftround' off indent not rounded to shiftwidth
'showcmd' + off command characters not shown
'showmode' + off current mode not shown
'smartcase' off no automatic ignore case switch
'smartindent' off no smart indentation
'smarttab' off no smart tab size
'softtabstop' 0 tabs are always 'tabstop' positions
'startofline' on goto startofline with some commands
'tagrelative' + off tag file names are not relative
'textauto' + off no automatic textmode detection
'textwidth' 0 no automatic line wrap
'tildeop' off tilde is not an operator
'ttimeout' off no terminal timeout
'whichwrap' + "" left-right movements don't wrap
'wildchar' + CTRL-E only when the current value is <Tab>
use CTRL-E for cmdline completion
*'complete'* *'cpt'*
'complete' 'cpt' string (default: ".,b")
global
{not in Vi}
This option specifies how keyword completion |ins-completion| works
when CTRL-P or CTRL-N are used. It indicates the type of completion
and the places to scan. It is a comma separated list of flags:
. scan the current buffer.
w scan other windows.
b scan other loaded buffers.
u scan the unloaded buffers.
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
i scan current and included files.
] 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
(gziped files for example)
A nice value is:
:set cpt=.,b,u
As U can see, CTRL-N and CTRL-P can be used to do any 'iskeyword'-
based expansion (eg dictionary |i_CTRL-X_CTRL-K|, include
|i_CTRL-X_CTRL-I|, tag |i_CTRL-X_CTRL-]| and normal expansions)
*'cpoptions'* *'cpo'*
'cpoptions' 'cpo' string (Vim default: "aABceFs",
Vi default: all flags)
global
{not in Vi}
A sequence of single character flags. When a character is present
this indicates vi-compatible behaviour. This is used for things where
not being vi-compatible is mostly or sometimes preferred.
'cpoptions' stands for 'compatibleoptions'.
Commas can be added for readability.
contains behaviour
a When included, a ":read" command with a file name
argument will set the alternate file name for the
current window.
A When included, a ":write" command with a file name
argument will set the alternate file name for the
current window.
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|.
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. This flag must be removed to be able to fully
use the <> notation. 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)
< 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 below.
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.
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.
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>.
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.
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.
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.
j When joining lines, only add two spaces after a '.',
not after '!' or '?'. Also see 'joinspaces'.
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 above.
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>
L When the 'list' option is set, 'wrapmargin' and
'textwidth' count a <Tab> as two characters, instead
of the normal behaviour of a <Tab>.
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'|
o Line offset to search command is not remembered for
next search.
r Redo ("." command) uses "/" to repeat a search
command, instead of the actually used search string.
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.
S Set buffer options always when entering a buffer
(except 'readonly' and 'fileformat'). 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.)
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.
u Undo is Vi compatible. See |undo-two-ways|.
w When using "cw" on a blank character, only change one
character and not all blanks until the start of the
next word.
W Don't overwrite a readonly file. When omitted, ":w!"
overwrites a readonly file, if possible.
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>|
y A yank command can be redone with ".".
$ 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.
! When redoing a filter command, use the last used
external command, whatever it was. Otherwise the last
used -filter- command is used.
% 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.
*'define'* *'def'*
'define' 'def' string (default "^#\s*define")
global
{not in Vi}
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 identifier name after the match. 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!
*'dictionary'* *'dict'*
'dictionary' 'dict' string (default "")
global
{not in Vi}
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).
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.
*'digraph'* *'dg'* *'nodigraph'* *'nodg'*
'digraph' 'dg' toggle (default off)
global
{not in Vi}
{not available when compiled without the |+digraphs|
feature}
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,/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.
- 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. That is
why a "tmp" directory in your home directory is used first.
{Vi: directory to put temp file in, defaults to "/tmp"}
*'ed'* *'edcompatible'* *'noed'* *'noedcompatible'*
'edcompatible' 'ed' toggle (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.
*'endofline'* *'eol'* *'noendofline'* *'noeol'*
'endofline' 'eol' toggle (default on)
local to buffer
{not in Vi}
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' toggle (default on)
global
{not in Vi}
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 the the window
above it.
*'equalprg'* *'ep'*
'equalprg' 'ep' string (default "")
global
{not in Vi}
External program to use for "=" command. When this option is empty
the internal formatting functions are used ('lisp' or 'cindent').
Environment variables are expanded |:set_env|. See |option-backslash|
about including spaces and backslashes.
*'errorbells'* *'eb'* *'noerrorbells'* *'noeb'*
'errorbells' 'eb' toggle (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 in Vi}
{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.
*'errorformat'* *'efm'*
'errorformat' 'efm' string (default is very long)
global
{not in Vi}
{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' toggle (Vim default: on, Vi default: off)
global
{not in Vi}
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.
*'eventignore'* *'ei'*
'eventignore' 'ei' string (default "")
global
{not in Vi}
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' toggle (default off)
local to buffer
{not in Vi}
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|.
*'exrc'* *'ex'* *'noexrc'* *'noex'*
'exrc' 'ex' toggle (default off)
global
{not in Vi}
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|.
*'fileformat'* *'ff'*
'fileformat' 'ff' string (DOS, Win32, OS/2 default: "dos",
Unix default: "unix",
Macintosh default: "mac")
local to buffer
{not in Vi}
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|.
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.
For backwards compatibility: When this option is set to "dos",
'textmode' is set, otherwise 'textmode' is reset.
*'fileformats'* *'ffs'*
'fileformats' 'ffs' string (Vim+Vi DOS, Win32, OS/2 default: "dos,unix",
Vim Unix default: "unix,dos",
Vim Mac default: "mac,unix,dos",
Vi others default: "")
global
{not in Vi}
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 prefered over "dos".
3. If 'fileformats' includes "mac", 'fileformat' is set to "mac".
This means that "mac" is only choosen 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.
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.
*'fkmap'* *'fk'* *'nofkmap'* *'nofk'*
'fkmap' 'fk' toggle (default off)
global
{not in Vi}
{only available when compiled with the |+rightleft|
feature}
When on, the keyboard is mapped for the Farsi character set.
Normally you would use CTRL-_ in insert mode to toggle this option.
See |farsi.txt|.
*'formatoptions'* *'fo'*
'formatoptions' 'fo' string (Vim default: "tcq", Vi default: "vt")
local to buffer
{not in Vi}
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.
*'formatprg'* *'fp'*
'formatprg' 'fp' string (default "")
global
{not in Vi}
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.
*'gdefault'* *'gd'* *'nogdefault'* *'nogd'*
'gdefault' 'gd' toggle (default off)
global
{not in Vi}
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
*'guicursor'* *'gcr'*
'guicursor' 'gcr' string (default "n-v-c:block-Cursor,o:hor50-Cursor,
i-ci:ver25-Cursor,r-cr:hor20-Cursor,
sm:block-Cursor-blinkwait175-
blinkoff150-blinkon175")
global
{not in Vi}
{Only available when compiled with GUI enabled}
This option tells Vim what the cursor should look like in different
modes. 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
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
tools/blink.c.
{group-name}
a highlight group name, that sets the color and font
for the cursor
Examples of parts:
n-c-v:block-nCursor in Normal, Command-lne 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 awcommon 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'*
'guifont' 'gfn' string (default "")
global
{not in Vi}
{Only available when compiled with GUI enabled}
This is a list of fonts which should be tried when starting the GUI
version of vim. The fonts are separated with commas. 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.
Win32 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 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
- takes these options in the font name:
hXX - height is XX (points)
wXX - width is XX (points)
b - bold
i - italic
u - underline
s - strikeout
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.
- Example:
:set guifont=courier_new:h12:w5:b
See also |font-sizes|.
*'guioptions'* *'go'*
'guioptions' 'go' string (default "agmr" (Unix) or "gmr")
global
{not in Vi}
{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. Valid letters are as follows:
'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.
'f' Foreground: Don't use fork() to detatch 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). Altenatively you
can use "gvim -f" or ":gui -f" to start the GUI in the
foreground. |gui-fork|
'm' Menu bar is present when 'm' is included.
'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.
'r' Right-hand scrollbar is present when 'r' is included.
'l' Left-hand scrollbar is present when 'l' is included.
'b' Bottom (horizontal) scrollbar is present when 'b' is included.
And yes, you may even have scrollbars on the left AND the right if
you really want to :-). See |gui-scrollbars| for more information.
*'guipty'* *'noguipty'*
'guipty' toggle (default on)
global
{not in Vi}
{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 (Amiga) "vim:doc/help.txt"
(MSDOS) "$VIM\doc\help.txt"
(others) "$VIM/doc/help.txt")
global
{not in Vi}
Name of the help file. All help files should be placed together in
one directory. Environment variables are expanded |:set_env|. For
example: "$VIM/doc/help.txt". If $VIM is not set, $HOME is also
tried. Also see |$VIM|. |option-backslash| about including spaces
and backslashes.
*'helpheight'* *'hh'*
'helpheight' 'hh' number (default 20)
global
{not in Vi}
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' toggle (default off)
global
{not in Vi}
When off the current buffer is unloaded when it is abandoned. When
on the current buffer becomes hidden when starting to edit another
buffer. If the current buffer is also displayed in another window it
does not become hidden, of course. The commands that move through the
buffer list sometimes make the current 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|.
*'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,t:Title,
v:Visual,w:WarningMsg")
global
{not in Vi}
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-return| 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-Visual| v Visual mode
|hl-WarningMsg| w warning messages
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' toggle (default off)
global
{not in Vi}
{not available when compiled without the
|+extra_search| feature}
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'.
When you switch this option on and off very often, it's a good idea to
make a mapping for this. Example:
:map <F7> :set hls!<CR>
Here is a mapping that also echoes the current value:
:map <F7> :set hls!<CR><Bar>:echo "HLSearch: " . strpart("OffOn", 3 * &hlsearch, 3)<CR>
*'history'* *'hi'*
'history' 'hi' number (Vim default: 20, Vi default: 0)
global
{not in Vi}
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|).
*'hkmap'* *'hk'* *'nohkmap'* *'nohk'*
'hkmap' 'hk' toggle (default off)
global
{not in Vi}
{only available when compiled with the |+rightleft|
feature}
When on, the keyboard is mapped for the Hebrew character set.
Normally you would use CTRL-_ in insert mode to toggle this option.
See |rightleft.txt|.
*'hkmapp'* *'hkp'* *'nohkmapp'* *'nohkp'*
'hkmapp' 'hkp' toggle (default off)
global
{not in Vi}
{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 |rightleft.txt|.
*'icon'* *'noicon'*
'icon' toggle (default off, on when title can be restored)
global
{not in Vi}
When on, the icon text of the window will be set 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 Unix xterm and iris-ansi). 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 in Vi}
When this options is not empty, it will be used for the icon of the
window. This happens regardless of the 'icon' option.
Only works if the terminal supports setting window icons (currently
only Unix xterm and iris-ansi). When Vim was compiled with HAVE_X11
defined, the original icon will be restored if possible |X11|.
*'ignorecase'* *'ic'* *'noignorecase'* *'noic'*
'ignorecase' 'ic' toggle (default off)
global
Ignore case in search patterns. Also used when searching in the tags
file.
*'include'* *'inc'*
'include' 'inc' string (default "^#\s*include")
global
{not in Vi}
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.
*'incsearch'* *'is'* *'noincsearch'* *'nois'*
'incsearch' 'is' toggle (default off)
global
{not in Vi}
{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'.
*'infercase'* *'inf'* *'noinfercase'* *'noinf'*
'infercase' 'inf' toggle (default off)
local to buffer
{not in Vi}
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 lower case. If the typed text
has no lower case letters and the match has a lower case letter where
the typed text has an upper case letter, and there is a letter before
it, the completed part is made uppercase.
*'insertmode'* *'im'* *'noinsertmode'* *'noim'*
'insertmode' 'im' toggle (default off)
global
{not in Vi}
Makes Vim work in a way that Insert mode is the default mode. Useful
if you want to use Vim as a modeless editor.
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|).
*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.
WARNING: this means that mappings that rely on the behaviour of
<Esc> will not work!
- 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*
*'isfname'* *'isf'*
'isfname' 'isf' string (default for MS-DOS, Win32 and OS/2:
"@,48-57,/,.,-,_,+,,,$,:,\"
for AMIGA: "@,48-57,/,.,-,_,+,,,$,:"
otherwise: "@,48-57,/,.,-,_,+,,,$,:,~")
global
{not in Vi}
The characters given by this option are included in file names and
path names. Filenames are used for commands like "gf", "[i" and in
the tags file. Besides the characters in this option characters that
are defined by the C function isalpha() are also always included
(this depends on the character set and "locale").
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, command 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
{not in Vi}
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. 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
{not in Vi}
Keywords are used in searching and recognizing with many commands:
"w", "*", "[i", etc. 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 '|'. When the 'lisp' option is on the '-' character is
always included.
*'isprint'* *'isp'*
'isprint' 'isp' string (default for MS-DOS and Win32: "@,~-255"
otherwise: "@,161-255")
global
{not in Vi}
The characters given by this option are displayed directly on the
screen. 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 "~?"
*'joinspaces'* *'js'* *'nojoinspaces'* *'nojs'*
'joinspaces' 'js' toggle (default on)
global
{not in Vi}
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.
*'keywordprg'* *'kp'*
'keywordprg' 'kp' string (default "man", "view /" for OS/2)
global
{not in Vi}
Program to use for the "K" command. Environment variables are
expanded |:set_env|. When empty ":help" is used. See
|option-backslash| about including spaces and backslashes.
*'langmap'* *'lmap'*
'langmap' 'lmap' string (default "")
global
{not in Vi}
{only available when compiled with the |+langmap|
feature}
This option allows support for keyboards that have a mode for a
special language. The idea is that when you are typing text in Insert
mode your keyboard is switched in the special language mode, you get
different key codes for the special characters. 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.
Example (for greek): *greek*
:set langmap=ÁA,ÂB,ØC,ÄD,ÅE,ÖF,ÃG,ÇH,ÉI,ÎJ,ÊK,ËL,ÌM,ÍN,ÏO,ÐP,QQ,ÑR,ÓS,ÔT,ÈU,ÙV,WW,×X,ÕY,ÆZ,áa,âb,øc,äd,åe,öf,ãg,çh,éi,îj,êk,ël,ìm,ín,ïo,ðp,qq,ñr,ós,ôt,èu,ùv,òw,÷x,õy,æz
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!
*'laststatus'* *'ls'*
'laststatus' 'ls' number (default 1)
global
{not in Vi}
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.
*'lazyredraw'* *'lz'*
'lazyredraw' 'lz' toggle (default off)
global
{not in Vi}
When this option is set, the screen will not be redrawn while
executing macros, registers and other commands that have not been
typed.
*'linebreak'* *'lbr'* *'nolinebreak'* *'nolbr'*
'linebreak' 'lbr' toggle (default off)
local to window
{not in Vi}
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. Note that <Tab>
characters after an <EOL> are mostly not displayed correctly.
*'lines'*
'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
you do set this, and Vim is unable to change the physical number of
lines on the display, redisplaying may be wrong.
*'lisp'* *'nolisp'*
'lisp' toggle (default off)
local to buffer
{not available when compiled without the |+lispindent|
feature}
Lisp mode: When a return 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 '-'
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 reset when
'paste' is set. {Vi: Does it a little bit differently}
*'list'* *'nolist'*
'list' toggle (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'.
*'magic'* *'nomagic'*
'magic' toggle (default on)
global
Changes the special characters that can be used in search patterns.
See |pattern|.
*'makeef'* *'mef'*
'makeef' 'mef' string (Amiga default: "t:vim##.Err",
Unix: "/tmp/vim##.err",
others: "vim##.err")
global
{not in Vi}
{not available when compiled without the |+quickfix|
feature}
Name of the errorfile for the ":make" command (see |:make_makeprg|).
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.
*'makeprg'* *'mp'*
'makeprg' 'mp' string (default "make")
global
{not in Vi}
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.
*'matchtime'* *'mat'*
'matchtime' 'mat' number (default 5)
global
{not in Vi}{in Nvi}
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.
*'maxmapdepth'* *'mmd'*
'maxmapdepth' 'mmd' number (default 1000)
global
{not in Vi}
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 512)
global
{not in Vi}
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. See also 'maxmemtot'.
*'maxmemtot'* *'mmt'*
'maxmemtot' 'mmt' number (default 2048, or half the amount of memory
available)
global
{not in Vi}
Maximum amount of memory (in Kbyte) to use for all buffers together.
See also 'maxmem'.
*'modeline'* *'ml'* *'nomodeline'* *'noml'*
'modeline' 'ml' toggle (Vim default: on, Vi default: off)
local to buffer
*'modelines'* *'mls'*
'modelines' 'mls' number (default 5)
global
{not in Vi}
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|. 'modeline' is reset when
'compatible' is set.
*'modified'* *'mod'* *'nomodified'* *'nomod'*
'modified' 'mod' toggle (default off)
local to buffer
{not in Vi}
When on the buffer is considered to be modified. This option is set
by every command that makes a change to the buffer. Only the undo
command may reset it, when all changes have been undone.
*'more'* *'nomore'*
'more' toggle (Vim default: on, Vi default: off)
global
{not in Vi}
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.
When 'compatible' is set this option is reset.
*'mouse'*
'mouse' string (default "", "a" for MS-DOS and Win32)
global
{not in Vi}
Enable the use of the mouse. Only works for certain terminals
(MS-DOS, Win32 |win32-mouse| and xterm). For using the mouse in the
GUI, see |gui-mouse|.
The mouse can be enabled for different modes:
n Normal mode
N Normal mode (see below)
v Visual mode
i Insert mode
I Insert mode (see below)
c Command-line mode
h all previous modes when editing a help file
a all previous modes except 'N' and 'I'
A all previous modes except 'n' and 'i'
r for |hit-return| prompt
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
xterm-like selection. This doesn't move the text cursor.
When 'N' or 'I' is included, the mouse is recognized in Normal or
Insert mode, but it only moves the cursor. It doesn't start Visual
mode. xterm-like selection is used. This mostly works Windows-like.
The normal way to start this is:
:set mouse=A
Note: When enabling the mouse in an xterm, the xterm copy/paste can
still be used by keeping the shift key pressed.
See |mouse-using|.
*'mousehide'* *'mh'* *'nomousehide'* *'nomh'*
'mousehide' 'mh' toggle (default off)
global
{not in Vi}
{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.
*'mousetime'* *'mouset'*
'mousetime' 'mouset' number (default 500)
global
{not in Vi}
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
{not in Vi}
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.
If "octal" is included, numbers that start with a zero will be
considered to be octal. Example: Using CTRL-A on "007" results in
"010".
If "hex" is 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' toggle (default off)
local to window
Print the line number in front of each line. Tip: If you don't like
wrapping lines to mix with the line numbers, set the 'showbreak'
option to eight spaces:
:set showbreak=\ \ \ \ \ \ \ \
*'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' toggle (default off)
global
{not in Vi}
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. When the 'paste' option is switched on (also when
it was already on):
- mapping in Insert mode is disabled
- abbreviations are disabled
- 'textwidth' is set to 0
- 'wrapmargin' is set to 0
- 'autoindent' is reset
- 'smartindent' is reset
- 'cindent' is reset
- 'softtabstop' is set to 0
- 'lisp' is reset
- 'revins' is reset
- 'ruler' is reset
- 'showmatch' is reset
- 'formatoptions' is used like it is empty
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. If
you use this often, you could map a function key to the command ":set
invpaste^V^M".
*'patchmode'* *'pm'*
'patchmode' 'pm' string (default "")
global
{not in Vi}
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 edited 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 succesfully 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.
*'path'* *'pa'*
'path' 'pa' string (default on Unix: ".,/usr/include,,"
on OS/2: ".,/emx/include,,"
other systems: ".,,")
global
{not in Vi}
This is a list of directories which will be searched when using the
gf, [f, ]f, ^Wf 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 where the current file is 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|.
- Use wildcards to specify directories more freely, e.g.,
:set path=/usr/include/*
means all subdirectories below /usr/include (but not /usr/include
itself).
- Use '**' if you want the whole subtree to be searched:
:set path=/home/user_x/src/**
means search in the whole subtree under "/home/usr_x/src". (to avoid
endless recursions, the depth is restricted to 100 levels)
- Give wildcards and recursions in any order:
:set path=/**/include/**
specifies a path with at least one directory /include/ in it.
- The set of allowed wildcards and the possible usage depend on the
operating system, but /etc/*/etc and /etc/**/etc work on any
system. |:_%<|
- 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|.
*'readonly'* *'ro'* *'noreadonly'* *'noro'*
'readonly' 'ro' toggle (default off)
local to buffer
{not in Vi}
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".
{not in Vi:} 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' toggle (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. For the ":substitute" command the number of
substitutions is used instead of the number of lines.
*'restorescreen'* *'rs'* *'norestorescreen'* *'nors'*
'restorescreen' 'rs' toggle (default on)
global
{not in Vi} {Windows 95/NT version only}
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' toggle (default off)
global
{not in Vi}
{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-B
command in Insert mode. This option is reset when 'compatible' or
'paste' is set.
*'rightleft'* *'rl'* *'norightleft'* *'norl'*
'rightleft' 'rl' toggle (default off)
local to window
{not in Vi}
{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 apear 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
sometimes usefull when editing Hebrew TeX--XeT files). See
|rightleft.txt|.
*'ruler'* *'ru'* *'noruler'* *'noru'*
'ruler' 'ru' toggle (default off)
global
{not in Vi}
Show the line and column number of the cursor position, separated by a
comma. 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 there are characters in the line that take two positions on the
screen, both the "real" column 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|.
*'scroll'* *'scr'*
'scroll' 'scr' number (default 'lines' / 2)
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 'lines' / 2 with
":set scroll=0". {difference from vi: 'scroll' gives the number of
screen lines instead of file lines, makes a difference when lines
wrap}
*'scrolljump'* *'sj'*
'scrolljump' 'sj' number (default 1)
global
{not in Vi}
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
{not in Vi}
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).
*'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'*
'secure' toggle (default off)
global
{not in Vi}
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.
*'shell'* *'sh'*
'shell' 'sh' string (default $SHELL or "sh",
MS-DOS and Win32: "command",
OS/2: "cmd")
global
Name of the shell to use for ! and :! commands. When changing the
value also check the 'shelltype', 'shellpipe' and 'shellredir'
options. 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|.
*'shellcmdflag'* *'shcf'*
'shellcmdflag' 'shcf' string (default: "-c", MS-DOS and Win32, when 'shell'
does not contain "sh" somewhere: "/c")
global
{not in Vi}
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|.
*'shellpipe'* *'sp'*
'shellpipe' 'sp' string (default ">", "| tee", "|& tee" or "2>&1| tee")|||
global
{not in Vi}
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.
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).
*'shellquote'* *'shq'*
'shellquote' 'shq' string (default: ""; MS-DOS and Win32, when 'shell'
contains "sh" somewhere: "\"")
global
{not in Vi}
Quoting character(s), put around the command passed to the shell, for
the "!" and ":!" commands. The redirection is kept outside of the
quoting. See 'shellxquoute' 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|.
*'shellredir'* *'srr'*
'shellredir' 'srr' string (default ">", ">&" or ">%s 2>&1")
global
{not in Vi}
String to be used to put the output of a filter 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.
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).
*'shelltype'* *'st'*
'shelltype' 'st' number (default 0)
global
{not in Vi}
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
{not in Vi}
Quoting character(s), put around the command passed to the shell, for
the "!" and ":!" commands. Includes the redirection. See
'shellxquoute' 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|.
*'shiftround'* *'sr'* *'noshiftround'* *'nosr'*
'shiftround' 'sr' toggle (default off)
global
{not in Vi}
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).
*'shiftwidth'* *'sw'*
'shiftwidth' 'sw' number (default 8)
local to buffer
Number of spaces to use for each step of (auto)indent.
*'shortmess'* *'shm'*
'shortmess' 'shm' string (default "")
global
{not in Vi}
This option helps to avoid all the |hit-return| 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.
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)
s don't give "search hit BOTTOM, continuing at TOP" or "search
hit TOP, continuing at BOTTOM" messages
t trunctate file message at the start if it is too long to fit
on the command line, "<" will appear in the left most column.
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 return, 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.
*'shortname'* *'sn'* *'noshortname'* *'nosn'*
'shortname' 'sn' toggle (default off)
local to buffer
{not in Vi, not in MS-DOS versions}
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.
*'showbreak'* *'sbr'*
'showbreak' 'sbr' string (default "")
global
{not in Vi}
String to put at the start of lines that have been wrapped. Useful
values are "> " or "+++ ". Only printable 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'.
*'showcmd'* *'sc'* *'noshowcmd'* *'nosc'*
'showcmd' 'sc' toggle (Vim default: on, off for Unix, Vi default:
off)
global
{not in Vi}
{not available when compiled without the |+showcmd|
feature}
Show (partial) command in status line. Set this option off if your
terminal is slow.
*'showmatch'* *'sm'* *'noshowmatch'* *'nosm'*
'showmatch' 'sm' toggle (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.
*'showmode'* *'smd'* *'noshowmode'* *'nosmd'*
'showmode' 'smd' toggle (Vim default: on, Vi default: off)
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.
*'sidescroll'* *'ss'*
'sidescroll' 'ss' number (default 0)
global
{not in Vi}
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.
When using a slow terminal set it to a large number or 0. When using
a fast terminal use a small number or 1. Not used for "zh" and "zl"
commands.
*'smartcase'* *'scs'* *'nosmartcase'* *'noscs'*
'smartcase' 'scs' toggle (default off)
global
{not in Vi}
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..
*'smartindent'* *'si'* *'nosmartindent'* *'nosi'*
'smartindent' 'si' toggle (default off)
local to buffer
{not in Vi}
{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.
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.
'smartindent' is reset when the 'paste' option is set.
*'smarttab'* *'sta'* *'nosmarttab'* *'nosta'*
'smarttab' 'sta' toggle (default off)
global
{not in Vi}
When on, a <Tab> in front of a line inserts 'shiftwidth' positions,
'tabstop' in other places. When off a <Tab> always inserts 'tabstop'
positions, 'shiftwidth' is only used for ">>" and the like. See also
|ins-expandtab|.
*'softtabstop'* *'sts'*
'softtabstop' 'sts' number (default 0)
local to buffer
{not in Vi}
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|.
*'splitbelow'* *'sb'* *'nosplitbelow'* *'nosb'*
'splitbelow' 'sb' toggle (default off)
global
{not in Vi}
When on, spliting a window will put the new window below the current
one.
*'startofline'* *'sol'* *'nostartofline'* *'nosol'*
'startofline' 'sol' toggle (default on)
global
{not in Vi}
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 and with "%" with a count. This option is
set when the 'compatible' option is set.
*'suffixes'* *'su'*
'suffixes' 'su' string (default ".bak,~,.o,.h,.info,.swp")
global
{not in Vi}
Files with these suffixes are ignored 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 include a dot or comma in a suffix, precede
it with a backslash (see |option-backslash| about including spaces and
backslashes).
*'swapsync'* *'sws'*
'swapsync' 'sws' string (default "fsync")
global
{not in Vi}
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.
*'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.
*'tagbsearch'* *'tbs'* *'notagbsearch'* *'notbs'*
'tagbsearch' 'tbs' toggle (default on)
global
{not in Vi}
Binary searching is first used in the tags files, when searching for a
tag (e.g., for the |:ta| command). This makes searching for a tag a
LOT faster. When no match was found in any of the files listed in
'tags', 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.
When this option is off, only the linear search is done. This makes
tags searching slower when a full match exists, but faster when no
full match exists. The number of tags found doesn't change, only the
order in which they are found.
When the tags file is not sorted, or sorted in a wrong way (not on
ASCII byte value), 'tagbsearch' should be off.
This option doesn't affect the |:tselect| command, and other commands
that find all matching tags (e.g., command line completion).
{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' toggle (Vim default: on, Vi default: off)
global
{not in Vi}
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. When
the 'compatible' option is set, this option is reset.
*'tags'* *'tag'*
'tags' 'tag' string (default "./tags,tags", when compiled with
|+emacs_tags|: "./tags,./TAGS,tags,TAGS")
global
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|.
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". |emacs-tags|
{Vi: default is "tags /usr/lib/tags"}
*'term'*
'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|.
*'terse'* *'noterse'*
'terse' toggle (default off)
global
{not in Vi}
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' toggle (Vim default: on, Vi default: off)
global
{not in Vi}
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.
*'textmode'* *'tx'* *'notextmode'* *'notx'*
'textmode' 'tx' toggle (MS-DOS, Win32 and OS/2: default on,
others: default off)
local to buffer
{not in Vi}
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
{not in Vi}
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|.
*'tildeop'* *'top'* *'notildeop'* *'notop'*
'tildeop' 'top' toggle (default off)
global
{not in Vi}
When on: The tilde command "~" behaves like an operator.
*'timeout'* *'to'* *'notimeout'* *'noto'*
'timeout' 'to' toggle (default on)
global
*'ttimeout'* *'nottimeout'*
'ttimeout' toggle (default off)
global
{not in Vi}
These two options together determine the behaviour when part of a
mapped key sequence or keyboard code has been received:
timeout ttimeout action
off off no time out
on on or off time out on :mappings and key codes
off on time out on key codes
If there is no time out, 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'. With a
time out 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 time 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 time out in 1 second, set the ttimeout option and
reset the timeout option.
*'timeoutlen'* *'tm'*
'timeoutlen' 'tm' number (default 1000)
global
{not in all versions of Vi}
*'ttimeoutlen'* *'ttm'*
'ttimeoutlen' 'ttm' number (default -1)
global
{not in Vi}
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' toggle (default off, on when title can be restored)
global
{not in Vi}
When on the title of the window will be set to "VIM - filename",
where filename is the name of the file currently being edited. Only
works if the terminal supports setting window titles (currently Amiga
console, Unix xterm and iris-ansi). Overridden by the 'titlestring'
option.
*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'|.
If the title cannot be restored, it is set to "Thanks for flying Vim".
You will have 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 $DISPLAY &
then the WINDOWID environment variable should be inherited and the
title of the window should change back to what it should be after
exiting Vim (rather than using the "Thanks..." message).
*'titlelen'*
'titlelen' number (default 85)
global
{not in Vi}
Gives the percentage of 'columns' to use for the length of the window
title. When the title is longer, only the end of the path name is
shown. A '>' character is used to indicate this. Using a percentage
makes this adapt to the width of the window. But it won't work
perfectly, because the actual number of characters available also
depends on the font used and other things in the title bar. When
'titlelen' is zero the full path is used. Otherwise, values from 1 to
30000 can be used. 'titlelen' is not used for the 'titlestring'
option.
*'titlestring'*
'titlestring' string (default "")
global
{not in Vi}
When this options is not empty, it will be used for the title of the
window. This happens regardless of the 'title' or 'titlelen' option.
Only works if the terminal supports setting window titles (currently
only Unix xterm and iris-ansi). When Vim was compiled with HAVE_X11
defined, the original title will be restored if possible |X11|.
Example:
let hostname = expand("`hostname`")
auto BufEnter * let &titlestring = hostname . "/" . expand("%:p")
*'ttybuiltin'* *'tbi'* *'nottybuiltin'* *'notbi'*
'ttybuiltin' 'tbi' toggle (default on)
global
{not in Vi}
When on, the builtin termcaps are searched before the external ones.
When off the builtin termcaps are searched after the external ones.
When this option is changed, you should set the 'term' option next for
the change to take effect, for example:
:set notbi term=$TERM
See also |termcap|.
*'ttyfast'* *'tf'* *'nottyfast'* *'notf'*
'ttyfast' 'tf' toggle (default off, on when 'term' is xterm, hpterm,
sun-cmd, scren, dtterm or iris-ansi)
global
{not in Vi}
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.
*'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 and OS/2)
global
{not in Vi}
Maximum number of changes that can be undone. Set to 0 for Vi
compatibility: one level of undo and "u" undoes itself. 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 (saves memory).
*'updatecount'* *'uc'*
'updatecount' 'uc' number (default: 200)
global
{not in Vi}
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. Also see |'swapsync'|.
*'updatetime'* *'ut'*
'updatetime' 'ut' number (default 4000)
global
{not in Vi}
If this many milliseconds nothing is typed the swap file will be
written to disk (see |crash-recovery|).
*'verbose'* *'vbs'*
'verbose' 'vbs' number (default 0)
global
{not in Vi}
When bigger than zero, Vim will give messages about what it is doing.
Currently, these messages are given:
>= 1 When a file is ":source"'ed.
>= 1 When the viminfo file is read or written.
>= 8 Files for which a group of autocommands is executed.
>= 9 Every executed autocommand.
This option can also be set with the "-V" argument. See |-V|.
*'viminfo'* *'vi'*
'viminfo' 'vi' string (default "")
global
{not in Vi}
{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
'' Maximum number of previously edited files for which the marks
are remembered. This parameter must always be included when
'viminfo' is non-empty.
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").
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.
" 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!
: 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 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.
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.
% 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.
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.
*'visualbell'* *'vb'* *'novisualbell'* *'novb'* *beep*
'visualbell' 'vb' toggle (default off)
global
{not in Vi}
Use visual bell instead of beeping. The terminal code to display the
visual bell is given with 't_vb'. When no beep of flash is wanted,
use ":set vb t_vb=". Does not work on the Amiga, you always get a
screen flash. Also see 'errorbells'.
*'warn'* *'nowarn'*
'warn' toggle (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' toggle (default off)
global
{not in Vi}
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
vise versa. Has no effect when the GUI is running.
*'whichwrap'* *'ww'*
'whichwrap' 'ww' string (Vim default: "b,s", Vi default: "")
global
{not in Vi}
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
[ <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.
When 'compatible' is set, 'whichwrap' is set to "".
*'wildchar'* *'wc'*
'wildchar' 'wc' number (Vim default: <Tab>, Vi default: CTRL-E)
global
{not in Vi}
Character you have to type to start wildcard expansion in the
command line. CTRL-E is used when the 'compatible' option is set.
The character is not recognized when used inside a macro. Although
'wc' is a number option, you can set it to a special key: ":set
wc=<Esc>".
*'winheight'* *'wh'*
'winheight' 'wh' number (default 0)
global
{not in Vi}
Minimal number of lines for the current window. 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. The
height is not adjusted after one of the commands to change the
height of the current window.
*'wrap'* *'nowrap'*
'wrap' toggle (default on)
local to window
{not in Vi}
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
(also see 'sidescroll' option and |wrap-off|). If you want to break
long lines, see 'textwidth'.
*'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 useful}
*'wrapscan'* *'ws'* *'nowrapscan'* *'nows'*
'wrapscan' 'ws' toggle (default on)
global
Searches wrap around the end of the file.
*'writeany'* *'wa'* *'nowriteany'* *'nowa'*
'writeany' 'wa' toggle (default off)
global
Allows writing to any file with no need for "!" override.
*'writebackup'* *'wb'* *'nowritebackup'* *'nowb'*
'writebackup' 'wb' toggle (default on with |+writebackup| feature, off
otherwise)
global
{not in Vi}
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.
*'writedelay'* *'wd'*
'writedelay' 'wd' number (default 0)
global
{not in Vi}
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.
