-
- Vim has a number of internal variables and switches which can be set to
- achieve special effects. These options come in three forms:
- boolean can only be on or off *boolean* *toggle*
- number has a numeric value
- string has a string value
-
- ==============================================================================
- 1. Setting options *set-option*
-
- *:se* *:set*
- :se[t] Show all options that differ from their default value.
-
- :se[t] all Show all but terminal options.
-
- :se[t] termcap Show all terminal options. Note that in the GUI the
- key codes are not shown, because they are generated
- internally and can't be changed. Changing the terminal
- codes in the GUI is not useful either...
-
- :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}
-
- *:set-default* *:set-&* *:set-&vi* *:set-&vim*
- :se[t] {option}& Reset option to its default value. May Depend on the
- current value of 'compatible'. {not in Vi}
- :se[t] {option}&vi Reset option to its Vi default value. {not in Vi}
- :se[t] {option}&vim Reset option to its Vim 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}.
- *:set-args*
- For numeric options the value can be given in decimal,
- hex (preceded with 0x) or octal (preceded with '0')
- (hex and octal are only available for machines which
- have the strtol() function).
- The old value can be inserted by typing 'wildchar' (by
- default this is a <Tab> or CTRL-E if 'compatible' is
- set). See |cmdline-completion|.
- White space between {option} and '=' is allowed and
- will be ignored. White space between '=' and {value}
- is not allowed.
- See |option-backslash| for using white space and
- backslashes in {value}.
-
- :se[t] {option}+={value} *:set+=*
- Add the {value} to a number option, or append the
- {value} to a string option. When the option is a
- comma separated list, a comma is added, unless the
- value was empty.
- If the option is a list of flags, superfluous flags
- are removed. Otherwise there is no check for doubled
- values. You can avoid this by removing a value first.
- Example: >
- :set guioptions-=T guioptions+=T
- < Also see |:set-args| above.
- {not in Vi}
-
- :se[t] {option}^={value} *:set^=*
- Multiply the {value} to a number option, or prepend
- the {value} to a string option. When the option is a
- comma separated list, a comma is added, unless the
- value was empty.
- Also see |:set-args| above.
- {not in Vi}
-
- :se[t] {option}-={value} *:set-=*
- Subtract the {value} from a number option, or remove
- the {value} from a string option, if it is there.
- If the {value} is not found in a string option, there
- is no error or warning. When the option is a comma
- separated list, a comma is deleted, unless the option
- becomes empty.
- When the option is a list of flags, {value} must be
- exactly as they appear in the option. Remove flags
- one by one to avoid problems.
- Also see |:set-args| above.
- {not in Vi}
-
- The {option} arguments to ":set" may be repeated. For example: >
- :set ai nosi sw=3 ts=3
- If you make an error in one of the arguments, an error message will be given
- and the following arguments will be ignored.
-
- *:set-verbose*
- When 'verbose' is non-zero, displaying an option value will also tell where it
- was last set. Example: >
- :verbose set shiftwidth cindent?
- shiftwidth=4
- Last set from modeline
- cindent
- Last set from /usr/local/share/vim/vim60/ftplugin/c.vim
- This is only done when specific option values are requested, not for ":set
- all" or ":set" without an argument.
- When the option was set by hand there is no "Last set" message. There is only
- one value for all local options with the same name. Thus the message applies
- to the option name, not necessarily its value.
- When the option was set while executing a function, user command or
- autocommand, the script in which it was defined is reported.
- {not available when compiled without the +eval feature}
-
- *:set-termcap*
- For {option} the form "t_xx" may be used to set a termcap option. This will
- override the value from the termcap. You can then use it in a mapping. If
- the "xx" part contains special characters, use the <t_xx> form: >
- :set <t_#4>=^[Ot
- This can also be used to translate a special code for a normal key. For
- example, if Alt-b produces <Esc>b, use this: >
- :set <M-b>=^[b
- (the ^[ is a real <Esc> here, use CTRL-V <Esc> to enter it)
- The advantage over a mapping is that it works in all situations.
-
- The listing from ":set" looks different from Vi. Long string options are put
- at the end of the list. The number of options is quite large. The output of
- "set all" probably does not fit on the screen, causing Vim to give the
- |more-prompt|.
-
- *option-backslash*
- To include white space in a string option value it has to be preceded with a
- backslash. To include a backslash you have to use two. Effectively this
- means that the number of backslashes in an option value is halved (rounded
- down).
- A few examples: >
- :set tags=tags\ /usr/tags results in "tags /usr/tags"
- :set tags=tags\\,file results in "tags\,file"
- :set tags=tags\\\ file results in "tags\ file"
-
- The "|" character separates a ":set" command from a following command. To
- include the "|" in the option value, use "\|" instead. This example sets the
- 'titlestring' option to "hi|there": >
- :set titlestring=hi\|there
- This sets the 'titlestring' option to "hi" and 'iconstring' to "there": >
- :set titlestring=hi|set iconstring=there
-
- For MS-DOS and WIN32 backslashes in file names are mostly not removed. More
- precise: For options that expect a file name (those where environment
- variables are expanded) a backslash before a normal file name character is not
- removed. But a backslash before a special character (space, backslash, comma,
- etc.) is used like explained above.
- There is one special situation, when the value starts with "\\": >
- :set dir=\\machine\path results in "\\machine\path"
- :set dir=\\\\machine\\path results in "\\machine\path"
- :set dir=\\path\\file results in "\\path\file" (wrong!)
- For the first one the start is kept, but for the second one the backslashes
- are halved. This makes sure it works both when you expect backslashes to be
- halved and when you expect the backslashes to be kept. The third gives a
- result which is probably not what you want. Avoid it.
-
- *add-option-flags* *remove-option-flags*
- Some options are a list of flags. When you want to add a flag to such an
- option, without changing the existing ones, you can do it like this: >
- :set guioptions+=a
- Remove a flag from an option like this: >
- :set guioptions-=a
- This removes the 'a' flag from 'guioptions'.
- Note that you should add or remove one flag at a time. If 'guioptions' has
- the value "ab", using "set guioptions-=ba" won't work, because the string "ba"
- doesn't appear.
-
- *:set_env* *expand-env* *expand-environment-var*
- Environment variables in most string options will be expanded. If the
- environment variable exists the '$' and the following environment variable
- name is replaced with its value. If it does not exist the '$' and the name
- are not modified. Any non-id character (not a letter, digit or '_') may
- follow the environment variable name. That character and what follows is
- appended to the value of the environment variable. Examples: >
- :set term=$TERM.new
- :set path=/usr/$INCLUDE,$HOME/include,.
- When adding or removing a string from an option with ":set opt-=val" or ":set
- opt+=val" the expansion is done before the adding or removing.
-
-
- Handling of local options *local-options*
-
- Some of the options only apply to a window or buffer. Each window or buffer
- has its own copy of this option, thus can each have their own value. This
- allows you to set 'list' in one window but not in another. And set
- 'shiftwidth' to 3 in one buffer and 4 in another.
-
- The following explains what happens to these local options in specific
- situations. You don't really need to know all of this, since Vim mostly uses
- the option values you would expect. Unfortunately, doing what the user
- expects is a bit complicated...
-
- When splitting a window, the local options are copied to the new window. Thus
- right after the split the contents of the two windows look the same.
-
- When editing a new buffer, its local option values must be initialized. Since
- the local options of the current buffer might be specifically for that buffer,
- these are not used. Instead, for each buffer-local option there also is a
- global value, which is used for new buffers. With ":set" both the local and
- global value is changed. With "setlocal" only the local value is changed,
- thus this value is not used when editing a new buffer.
-
- When editing a buffer that has been edited before, the last used window
- options are used again. If this buffer has been edited in this window, the
- values from back then are used. Otherwise the values from the window where
- the buffer was edited last are used.
-
- It's possible to set a local window option specifically for a type of buffer.
- When you edit another buffer in the same window, you don't want to keep
- using these local window options. Therefore Vim keeps a global value of the
- local window options, which is used when editing another buffer. Each window
- has its own copy of these values. Thus these are local to the window, but
- global to all buffers in the window. With this you can do: >
- :e one
- :set list
- :e two
- Now the 'list' option will also be set in "two", since with the ":set list"
- command you have also set the global value. >
- :set nolist
- :e one
- :setlocal list
- :e two
- Now the 'list' option is not set, because ":set nolist" resets the global
- value, ":setlocal list" only changes the local value and ":e two" gets the
- global value. Note that if you do this next: >
- :e one
- You will not get back the 'list' value as it was the last time you edited
- "one". The options local to a window are not remembered for each buffer.
-
- *:setl* *:setlocal*
- :setl[ocal] ... Like ":set" but set only the value local to the
- current buffer or window (if there is one).
- With the "all" argument: display all local option's
- local values.
- Without argument: Display all local option's local
- values which are different from the default.
- When displaying a specific local option, show the
- local value. For a global option the global value is
- shown (but that might change in the future).
- {not in Vi}
-
- :setl[ocal] {option}< Set the local value of {option} to its global value.
- {not in Vi}
-
- *:setg* *:setglobal*
- :setg[lobal] ... Like ":set" but set only the global value for a local
- option without changing the local value.
- When displaying an option, the global value is shown.
- With the "all" argument: display all local option's
- global values.
- Without argument: display all local option's global
- values which are different from the default.
- {not in Vi}
-
- For buffer-local and window-local options:
- Command global value local value ~
- :set option=value set set
- :setlocal option=value - set
- :setglobal option=value set -
- :set option - display
- :setlocal option - display
- :setglobal option display -
-
-
- Global options with a local value *global-local*
-
- Options are global when you mostly use one value for all buffers. For some
- global options it's useful to sometimes have a different local value. You can
- set the local value with ":setlocal". That buffer will then use the local
- value, while other buffers continue using the global value.
-
- For example, you have two windows, both on C source code. They use the global
- 'makeprg' option. If you do this in one of the two windows: >
- :set makeprg=gmake
- then the other window will switch to the same value. There is no need to set
- the 'makeprg' option in the other C source window too.
- However, if you start editing a Perl file in a new window, you want to use
- another 'makeprog' for it, without changing the value used for the C source
- files. You use this command: >
- :setlocal makeprg=perlmake
- You can switch back to using the global value by making the local value empty: >
- :setlocal makeprg=
- This only works for a string option. For a boolean option you need to use the
- "<" flag, like this: >
- :setlocal autoread<
- Note that for non-boolean options using "<" copies the global value to the
- local value, it doesn't switch back to using the global value (that matters
- when changing the global value later).
- Note: In the future more global options can be made global-local. Using
- ":setlocal" on a global option might work differently then.
-
-
- Setting the filetype
-
- :setf[iletype] {filetype} *:setf* *:setfiletype*
- Set the 'filetype' option to {filetype}, but only if
- not done yet in a sequence of (nested) autocommands.
- This is short for: >
- :if !did_filetype()
- : setlocal filetype={filetype}
- :endif
- < This command is used in a filetype.vim file to avoid
- setting the 'filetype' option twice, causing different
- settings and syntax files to be loaded.
- {not in Vi}
-
- :bro[wse] se[t] *:set-browse* *:browse-set* *:opt* *:options*
- :opt[ions] Open a window for viewing and setting all options.
- Options are grouped by function.
- Offers short help for each option. Hit <CR> on the
- short help to open a help window with more help for
- the option.
- Modify the value of the option and hit <CR> on the
- "set" line to set the new value. For window and
- buffer specific options, the last accessed window is
- used to set the option value in, unless this is a help
- window, in which case the window below help window is
- used (skipping the option-window).
- {not available when compiled without the |+eval| or
- |+autocmd| features}
-
- *$HOME*
- Using "~" is like using "$HOME", but it is only recognized at the start of an
- option and after a space or comma.
-
- On Unix systems "~user" can be used too. It is replaced by the home directory
- of user "user". Example: >
- :set path=~mool/include,/usr/include,.
-
- On Unix systems the form "${HOME}" can be used too. The name between {} can
- contain non-id characters then. Note that if you want to use this for the
- "gf" command, you need to add the '{' and '}' characters to 'isfname'.
-
-
- Note the maximum length of an expanded option is limited. How much depends on
- the system, mostly it is something like 256 or 1024 characters.
-
- *:fix* *:fixdel*
- :fix[del] Set the value of 't_kD':
- 't_kb' is 't_kD' becomes ~
- CTRL-? CTRL-H
- not CTRL-? CTRL-?
-
- (CTRL-? is 0177 octal, 0x7f hex) {not in Vi}
-
- If your delete key terminal code is wrong, but the
- code for backspace is alright, you can put this in
- your .vimrc: >
- :fixdel
- < This works no matter what the actual code for
- backspace is.
-
- If the backspace key terminal code is wrong you can
- use this: >
- :if &term == "termname"
- : set t_kb=^V<BS>
- : fixdel
- :endif
- < Where "^V" is CTRL-V and "<BS>" is the backspace key
- (don't type four characters!). Replace "termname"
- with your terminal name.
-
- If your <Delete> key sends a strange key sequence (not
- CTRL-? or CTRL-H) you cannot use ":fixdel". Then use: >
- :if &term == "termname"
- : set t_kD=^V<Delete>
- :endif
- < Where "^V" is CTRL-V and "<Delete>" is the delete key
- (don't type eight characters!). Replace "termname"
- with your terminal name.
-
- *Linux-backspace*
- Note about Linux: By default the backspace key
- produces CTRL-?, which is wrong. You can fix it by
- putting this line in your rc.local: >
- echo "keycode 14 = BackSpace" | loadkeys
- <
- *NetBSD-backspace*
- Note about NetBSD: If your backspace doesn't produce
- the right code, try this this: >
- xmodmap -e "keycode 22 = BackSpace"
- < If this works, add this in your .Xmodmap file: >
- keysym 22 = BackSpace
- < You need to restart for this to take effect.
-
- ==============================================================================
- 2. Automatically setting options *auto-setting*
-
- Besides changing options with the ":set" command, there are three alternatives
- to set options automatically for one or more files:
-
- 1. When starting Vim initializations are read from various places. See
- |initialization|. Most of them are performed for all editing sessions,
- and some of them depend on the directory where Vim is started.
- You can create an initialization file with |:mkvimrc|, |:mkview| and
- |:mksession|.
- 2. If you start editing a new file, the automatic commands are executed.
- This can be used to set options for files matching a particular pattern and
- many other things. See |autocommand|.
- 3. If you start editing a new file, and the 'modeline' option is on, a
- number of lines at the beginning and end of the file are checked for
- modelines. This is explained here.
-
- *modeline* *vim:* *vi:* *ex:*
- 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:").
-
- *modeline-local*
- The options are set like with ":setlocal": The new value only applies to the
- buffer that contains the window. Although it's possible to set global options
- from a modeline, this is unusual. If you have two windows open and the files
- in it set the same global option to a different value, the result depends on
- which one was opened last.
-
- *modeline-version*
- If the modeline is only to be used for some versions of Vim, the version
- number can be specified where "vim:" is used:
- vim{vers}: version {vers} or later
- vim<{vers}: version before {vers}
- vim={vers}: version {vers}
- vim>{vers}: version after {vers}
- {vers} is 600 for Vim 6.0 (hundred times the major version plus minor).
- For example, to use a modeline only for Vim 6.0 and later: >
- /* vim600: set foldmethod=marker: */
- To use a modeline for Vim before version 5.7: >
- /* vim<570: set sw=4: */
- There can be no blanks between "vim" and the ":".
-
-
- The number of lines that are checked can be set with the 'modelines' option.
- If 'modeline' is off or 'modelines' is 0 no lines are checked.
-
- Note that for the first form all of the rest of the line is used, thus a line
- like: >
- /* vi:ts=4: */
- will give an error message for the trailing "*/". This line is OK: >
- /* vi:set ts=4: */
-
- If an error is detected the rest of the line is skipped.
-
- If you want to include a ':' in a set command precede it with a '\'. The
- backslash in front of the ':' will be removed. Example: >
- /* vi:set dir=c\:\tmp: */
- This sets the 'dir' option to "c:\tmp". Only a single backslash before the
- ':' is removed. Thus to include "\:" you have to specify "\\:".
-
- No other commands than "set" are supported, for security reasons (somebody
- might create a Trojan horse text file with modelines).
-
- Hint: If you would like to do something else than setting an option, you could
- define an autocommand that checks the file for a specific string. For
- example: >
- au BufReadPost * if getline(1) =~ "VAR" | call SetVar() | endif
- And define a function SetVar() that does something with the line containing
- "VAR".
-
- ==============================================================================
- 3. Options summary *option-summary*
-
- In the list below all the options are mentioned with their full name and with
- an abbreviation if there is one. Both forms may be used.
-
- In this document when a boolean option is "set" that means that ":set option"
- is entered. When an option is "reset", ":set nooption" is used.
-
- For some options there are two default values: The "Vim default", which is
- used when 'compatible' is not set, and the "Vi default", which is used when
- 'compatible' is set.
-
- Most options are the same in all windows and buffers. There are a few that
- are specific to how the text is presented in a window. These can be set to a
- different value in each window. For example the 'list' option can be set in
- one window and reset in another for the same text, giving both types of view
- at the same time. There are a few options that are specific to a certain
- file. These can have a different value for each file or buffer. For example
- the 'textwidth' option can be 78 for a normal text file and 0 for a C
- program.
-
- global one option for all buffers and windows
- local to window each window has its own copy of this option
- local to buffer each buffer has its own copy of this option
-
- When creating a new window the option values from the currently active window
- are used as a default value for the window-specific options. For the
- buffer-specific options this depends on the 's' and 'S' flags in the
- 'cpoptions' option. If 's' 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.
-
- *E355*
- A jump table for the options with a short description can be found at |Q_op|.
-
- *'aleph'* *'al'* *aleph* *Aleph*
- 'aleph' 'al' number (default 128 for MS-DOS, 224 otherwise)
- global
- {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 |rileft.txt|.
-
- *'allowrevins'* *'ari'* *'noallowrevins'* *'noari'*
- 'allowrevins' 'ari' boolean (default off)
- global
- {not in Vi}
- {only available when compiled with the |+rightleft|
- feature}
- Allow CTRL-_ in Insert and Command-line mode. This is default off, to
- avoid that users that accidentally type CTRL-_ instead of SHIFT-_ get
- into reverse Insert mode, and don't know how to get out. See
- 'revins'.
- NOTE: This option is reset when 'compatible' is set.
-
- *'altkeymap'* *'akm'* *'noaltkeymap'* *'noakm'*
- 'altkeymap' 'akm' boolean (default off)
- global
- {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 'allowrevins' set.
-
- When off, the keyboard map toggles between Hebrew and English. This
- is useful to start the vim in native mode i.e. English (left-to-right
- mode) and have default second language Farsi or Hebrew (right-to-left
- mode). See |farsi.txt|.
-
- *'autoindent'* *'ai'* *'noautoindent'* *'noai'*
- 'autoindent' 'ai' boolean (default off)
- local to buffer
- Copy indent from current line when starting a new line (typing <CR>
- in Insert mode or when using the "o" or "O" command). If you do not
- type anything on the new line except <BS> or CTRL-D and then type
- <Esc> or <CR>, the indent is deleted again. When autoindent is on,
- formatting (with the "gq" command or when you reach 'textwidth' in
- Insert mode) uses the indentation of the first line.
- When 'smartindent' or 'cindent' is on the indent is changed in
- a different way.
- The 'autoindent' option is reset when the 'paste' option is set.
- {small difference from Vi: After the indent is deleted when typing
- <Esc> or <CR>, the cursor position when moving up or down is after the
- deleted indent; Vi puts the cursor somewhere in the deleted indent}.
-
- *'autoread'* *'ar'* *'noautoread'* *'noar'*
- 'autoread' 'ar' boolean (default off)
- global or local to buffer |global-local|
- {not in Vi}
- When a file has been detected to have been changed outside of Vim and
- it has not been changed inside of Vim, automatically read it again.
- When the file has been deleted this is not done. |timestamp|
- If this option has a local value, use this command to switch back to
- using the global value: >
- :set autoread<
- <
- *'autowrite'* *'aw'* *'noautowrite'* *'noaw'*
- 'autowrite' 'aw' boolean (default off)
- global
- Write the contents of the file, if it has been modified, on each
- :next, :rewind, :last, :first, :previous, :stop, :suspend, :tag, :!,
- :make, CTRL-] and CTRL-^ command; and when a CTRL-O, CTRL-I,
- '{A-Z0-9}, or `{A-Z0-9} command takes one to another file.
- Note that for some commands the 'autowrite' option is not used, see
- 'autowriteall' for that.
-
- *'autowriteall'* *'awa'* *'noautowriteall'* *'noawa'*
- 'autowriteall' 'awa' boolean (default off)
- global
- {not in Vi}
- Like 'autowrite', but also used for commands ":edit", ":quit",
- ":qall", ":exit", ":xit", ":recover" and closing the Vim window.
- Setting this option also implies that Vim behaves like 'autowrite' has
- been set.
-
- *'background'* *'bg'*
- 'background' 'bg' string (default "dark" or "light")
- global
- {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.
- Setting this option does not change the background color, it tells Vim
- what the background color looks like. For changing the background
- color, see |:hi-normal|.
-
- When 'background' is set Vim will adjust the default color groups for
- the new value. But the colors used for syntax highlighting will not
- change.
- When a color scheme is loaded (the "colors_name" variable is set)
- setting 'background' will cause the color scheme to be reloaded. If
- the color scheme adjusts to the value of 'background' this will work.
- However, if the color scheme sets 'background' itself the effect may
- be undone. First delete the "colors_name" variable when needed.
-
- When setting 'background' to the default value with: >
- :set background&
- < Vim will guess the value. In the GUI this should work correctly,
- in other cases Vim might not be able to guess the right value.
-
- When starting the GUI, the default value for 'background' will be
- "light". When the value is not set in the .gvimrc, and Vim detects
- that the background is actually quite dark, 'background' is set to
- "dark". But this happens only AFTER the .gvimrc file has been read
- (because the window needs to be opened to find the actual background
- color). To get around this, force the GUI window to be opened by
- putting a ":gui" command in the .gvimrc file, before where the value
- of 'background' is used (e.g., before ":syntax on").
- 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 "$VIMRUNTIME/syntax/syntax.vim" file
- to select the colors for syntax highlighting. After changing this
- option, you must load syntax.vim again to see the result. This can be
- done with ":syntax on".
-
- *'backspace'* *'bs'*
- 'backspace' 'bs' string (default "")
- global
- {not in Vi}
- Influences the working of <BS>, <Del>, CTRL-W and CTRL-U in Insert
- mode. This is a list of items, separated by commas. Each item allows
- a way to backspace over something:
- value effect ~
- indent allow backspacing over autoindent
- eol allow backspacing over line breaks (join lines)
- start allow backspacing over the start of insert; CTRL-W and CTRL-U
- stop once at the start of insert.
-
- When the value is empty, Vi compatible backspacing is used.
-
- For backwards compatibility with version 5.4 and earlier:
- value effect ~
- 0 same as "" (Vi compatible)
- 1 same as "indent,eol"
- 2 same as "indent,eol,start"
-
- See |:fixdel| if your <BS> or <Del> key does not do what you want.
- NOTE: This option is set to "" when 'compatible' is set.
-
- *'backup'* *'bk'* *'nobackup'* *'nobk'*
- 'backup' 'bk' boolean (default off)
- global
- {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.
- When the 'backupskip' pattern matches, a backup is not made anyway.
- When 'patchmode' is set, the backup may be renamed to become the
- oldest version of a file.
- NOTE: This option is reset when 'compatible' is set.
-
- *'backupcopy'* *'bkc'*
- 'backupcopy' 'bkc' string (Vi default for Unix: "yes", otherwise: "auto")
- global
- {not in Vi}
- When writing a file and a backup is made, this option tells how it's
- done:
- "yes" make a copy of the file and overwrite the original one
- "no" rename the file and write a new one
- "auto" one of the previous, what works best
-
- Making a copy and overwriting the original file:
- - Takes extra time to copy the file.
- + When the file has special attributes, is a (hard/symbolic) link or
- has a resource fork, all this is preserved.
- - When the file is a link the backup will have the name of the link,
- not of the real file.
-
- Renaming the file and writing a new one:
- + It's fast.
- - Sometimes not all attributes of the file can be copied to the new
- file.
- - When the file is a link the new file will not be a link.
-
- The "auto" value is the middle way: When Vim sees that renaming file
- is possible without side effects (the attributes can be passed on and
- and the file is not a link) that is used. When problems are expected,
- a copy will be made.
-
- One situation where "no" and "auto" will cause problems: A program
- that opens a file, invokes Vim to edit that file, and then tests if
- the open file was changed (through the file descriptor) will check the
- backup file instead of the newly created file. "crontab -e" is an
- example.
-
- When a copy is made, the original file is truncated and then filled
- with the new text. This means that protection bits, owner and
- symbolic links of the original file are unmodified. The backup file
- however, is a new file, owned by the user who edited the file. The
- group of the backup is set to the group of the original file. If this
- fails, the protection bits for the group are made the same as for
- others.
-
- When the file is renamed this is the other way around: The backup has
- the same attributes of the original file, and the newly written file
- is owned by the current user. When the file was a (hard/symbolic)
- link, the new file will not! That's why the "auto" value doesn't
- rename when the file is a link. The owner and group of the newly
- written file will be set to the same ones as the original file, but
- the system may refuse to do this. In that case the "auto" value will
- again not rename the file.
-
- *'backupdir'* *'bdir'*
- 'backupdir' 'bdir' string (default for Amiga: ".,t:",
- for MS-DOS and Win32: ".,c:/tmp,c:/temp"
- for Unix: ".,~/tmp,~/")
- global
- {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.
- ("." inside a directory name has no special meaning).
- - Spaces after the comma are ignored, other spaces are considered part
- of the directory name. To have a space at the start of a directory
- name, precede it with a backslash.
- - To include a comma in a directory name precede it with a backslash.
- - A directory name may end in an '/'.
- - Environment variables are expanded |:set_env|.
- - Careful with '\' characters, type one before a space, type two to
- get one in the option (see |option-backslash|), for example: >
- :set bdir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
- < - For backwards compatibility with Vim version 3.0 a '>' at the start
- of the option is removed.
- See also 'backup' and 'writebackup' options.
- If you want to hide your backup files on Unix, consider this value: >
- :set backupdir=./.backup,~/.backup,.,/tmp
- < You must create a ".backup" directory in each directory and in your
- home directory for this to work properly.
- The use of |:set+=| and |:set-=| is preferred when adding or removing
- directories from the list. This avoids problems when a future version
- uses another default.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'backupext'* *'bex'*
- 'backupext' 'bex' string (default "~", for VMS: "_")
- 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
- accidentally overwriting existing files with a backup file. You might
- prefer using ".bak", but make sure that you don't have files with
- ".bak" that you want to keep.
-
- *'backupskip'* *'bsk'*
- 'backupskip' 'bsk' string (default: "/tmp/*,$TMPDIR/*,$TMP/*,$TEMP/*")
- global
- {not in Vi}
- {not available when compiled without the |+wildignore|
- feature}
- A list of file patterns. When one of the patterns matches with the
- name of the file which is written, no backup file is created. Both
- the specified file name and the full path name of the file are used.
- The pattern is used like with |:autocmd|, see |autocmd-patterns|.
- Watch out for special characters, see |option-backslash|.
- When $TMPDIR, $TMP or $TEMP is not defined, it is not used for the
- default value. "/tmp/*" is only used for Unix.
-
- *'balloondelay'* *'bdlay'*
- 'balloondelay' 'bdlay' number (default: 600)
- global
- {not in Vi}
- {only available when compiled with the |+balloon_eval|
- feature}
- Delay in milliseconds before a balloon may pop up. See |balloon-eval|.
-
- *'ballooneval'* *'beval'* *'noballooneval'* *'nobeval'*
- 'ballooneval' 'beval' boolean (default off)
- global
- {not in Vi}
- {only available when compiled with the |+balloon_eval|
- and |+sun_workshop| features}
- Switch on the |balloon-eval| functionality.
-
- *'binary'* *'bin'* *'nobinary'* *'nobin'*
- 'binary' 'bin' boolean (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).
- The 'fileencoding' and 'fileencodings' options will not be used, the
- file is read without conversion.
- NOTE: When you start editing a(nother) file while the 'bin' option is
- on, settings from autocommands may change the settings again (e.g.,
- 'textwidth'), causing trouble when editing. You might want to set
- 'bin' again when the file has been loaded.
- The previous values of these options are remembered and restored when
- 'bin' is switched from on to off. Each buffer has its own set of
- saved option values.
- When writing a file the <EOL> for the last line is only written if
- there was one in the original file (normally Vim appends an <EOL> to
- the last line if there is none; this would make the file longer). See
- the 'endofline' option.
-
- *'bioskey'* *'biosk'* *'nobioskey'* *'nobiosk'*
- 'bioskey' 'biosk' boolean (default on)
- global
- {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.
- Also see |'conskey'|.
-
- *'bomb'* *'nobomb'*
- 'bomb' boolean (default off)
- local to buffer
- {not in Vi}
- {only available when compiled with the |+multi_byte|
- feature}
- When writing a file and the following conditions are met, a BOM (Byte
- Order Mark) is prepended to the file:
- - this option is on
- - the 'binary' option is off
- - 'fileencoding' is "utf-8", "ucs-2", "ucs-4" or one of the little/big
- endian variants.
- Some applications use the BOM to recognize the encoding of the file.
- Often used for UCS-2 files on MS-Windows. For other applications it
- causes trouble, for example: "cat file1 file2" makes the BOM of file2
- appear halfway the file.
- When Vim reads a file and 'fileencodings' starts with "ucs-bom", a
- check for the presence of the BOM is done and 'bomb' set accordingly.
- Unless 'binary' is set, it is removed from the first line, so that you
- don't see it when editing. When you don't change the options, the BOM
- will be restored when writing the file.
-
- *'breakat'* *'brk'*
- 'breakat' 'brk' string (default " ^I!@*-+;:,./?")
- global
- {not in Vi}
- {not available when compiled without the |+linebreak|
- feature}
- This option lets you choose which characters might cause a line
- break if 'linebreak' is on.
-
- *'browsedir'* *'bsdir'*
- 'browsedir' 'bsdir' string (default for "last")
- global
- {not in Vi} {only for Motif and Win32 GUI}
- Which directory to use for the file browser:
- last Use same directory as with last file browser.
- buffer Use the directory of the related buffer.
- current Use the current directory.
- {path} Use the specified directory
-
- *'bufhidden'* *'bh'*
- 'bufhidden' 'bh' string (default: "")
- local to buffer
- {not in Vi}
- {not available when compiled without the |+quickfix|
- feature}
- This option specifies what happens when a buffer is no longer
- displayed in a window:
- <empty> follow the global 'hidden' option
- hide hide the buffer (don't unload it), also when 'hidden'
- is not set
- unload unload the buffer, also when 'hidden' is set or using
- |:hide|
- delete delete the buffer from the buffer list, also when
- 'hidden' is set or using |:hide|, like using
- |:bdelete|
-
- This option is used together with 'buftype' and 'swapfile' to specify
- special kinds of buffers. See |special-buffers|.
-
- *'buflisted'* *'bl'* *E85*
- 'buflisted' 'bl' boolean (default: on)
- local to buffer
- {not in Vi}
- When this option is set, the buffer shows up in the buffer list. If
- it is reset it is not used for ":bnext", "ls", the Buffers menu, etc.
- This option is reset by Vim for buffers that are only used to remember
- a file name or marks. Vim sets it when starting to edit a buffer.
- But not when moving to a buffer with ":buffer".
-
- *'buftype'* *'bt'* *E382*
- 'buftype' 'bt' string (default: "")
- local to buffer
- {not in Vi}
- {not available when compiled without the |+quickfix|
- feature}
- The value of this option specifies the type of a buffer:
- <empty> normal buffer
- nofile buffer which is not related to a file and will not be
- written
- nowrite buffer which will not be written
- quickfix quickfix buffer, contains list of errors |:cwindow|
- help help buffer (you are not supposed to set this
- manually)
-
- This option is used together with 'bufhidden' and 'swapfile' to
- specify special kinds of buffers. See |special-buffers|.
-
- Be careful with changing this option, it can have many side effects!
-
- A "quickfix" buffer is only used for the error list. This value is
- set by the |:cwindow| command and you are not supposed to change it.
-
- "nofile" and "nowrite" buffers are similar:
- both: The buffer is not to be written to disk, ":w" doesn't
- work (":w filename" does work though).
- both: The buffer is never considered to be |'modified'|.
- There is no warning when the changes will be lost, for
- example when you quit Vim.
- both: A swap file is only created when using too much memory
- (when 'swapfile' has been reset there is never a swap
- file).
- nofile only: The buffer name is fixed, it is not handled like a
- file name. It is not modified in response to a |:cd|
- command.
-
- *'cdpath'* *'cd'* *E344* *E346*
- 'cdpath' 'cd' string (default: equivalent to $CDPATH or ",,")
- global
- {not in Vi}
- {not available when compiled without the
- |+file_in_path| feature}
- This is a list of directories which will be searched when using the
- |:cd| and |:lcd| commands, provided that the directory being searched
- for has a relative path (not starting with "/", "./" or "../").
- The 'cdpath' option's value has the same form and semantics as
- |'path'|. Also see |file-searching|.
- The default value is taken from $CDPATH, with a "," prepended to look
- in the current directory first.
- If the default value taken from $CDPATH is not what you want, include
- a modified version of the following command in your vimrc file to
- override it: >
- :let &cdpath = ',' . substitute(substitute($CDPATH, '[, ]', '\\\0', 'g'), ':', ',', 'g')
- < This option cannot be set from a |modeline|, for security reasons
- (parts of 'cdpath' can be passed to the shell to expand file names).
-
- *'cedit'*
- 'cedit' string (Vi default: "", Vim default: CTRL-F)
- global
- {not in Vi}
- {not available when compiled without the |+vertsplit|
- feature}
- The key used in Command-line Mode to open the command-line window.
- The default is CTRL-F when 'compatible' is off.
- Only non-printable keys are allowed.
- The key can be specified as a single character, but it is difficult to
- type. The preferred way is to use the <> notation. Examples: >
- :set cedit=<C-Y>
- :set cedit=<Esc>
- < |Nvi| also has this option, but it only uses the first character.
- See |cmdwin|.
-
- *'charconvert'* *'ccv'* *E202* *E214*
- 'charconvert' 'ccv' string (default "")
- global
- {only available when compiled with the |+multi_byte|
- feature and the |+eval| feature}
- {not in Vi}
- An expression that is used for character encoding conversion. It is
- evaluated when a file that is to be read or has been written has a
- different encoding from what is desired.
- 'charconvert' is not used when the internal iconv() function is
- supported and is able to do the conversion. Using iconv() is
- preferred, because it is much faster.
- 'charconvert' is not used when reading stdin |--|, because there is no
- file to convert from. You will have to save the text in a file first.
- The expression must return zero or an empty string for success,
- non-zero for failure.
- The possible encoding names encountered are in 'encoding'.
- Additionally, names given in 'fileencodings' and 'fileencoding' are
- used.
- Conversion between "latin1", "unicode", "ucs-2", "ucs-4" and "utf-8"
- is done internally by Vim, 'charconvert' is not used for this.
- 'charconvert' is also used to convert the viminfo file, if the 'c'
- flag is present in 'viminfo'. Also used for Unicode conversion.
- Example: >
- set charconvert=CharConvert()
- fun CharConvert()
- system("recode "
- \ . v:charconvert_from . ".." . v:charconvert_to
- \ . " <" . v:fname_in . " >" v:fname_out)
- return v:shell_error
- endfun
- < The related Vim variables are:
- v:charconvert_from name of the current encoding
- v:charconvert_to name of the desired encoding
- v:fname_in name of the input file
- v:fname_out name of the output file
- Note that v:fname_in and v:fname_out will never be the same.
- Note that v:charconvert_from and v:charconvert_to may be different
- from 'encoding'. Vim internally uses UTF-8 instead of UCS-2 or UCS-4.
- Encryption is not done by Vim when using 'charconvert'. If you want
- to encrypt the file after conversion, 'charconvert' should take care
- of this.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'cindent'* *'cin'* *'nocindent'* *'nocin'*
- 'cindent' 'cin' boolean (default off)
- local to buffer
- {not 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 'indentexpr' is not empty, it overrules 'cindent'.
- If 'lisp' is not on and both 'indentexpr' and 'equalprg' are empty,
- the "=" operator indents using this algorithm rather than calling an
- external program.
- See |C-indenting|.
- When you don't like the way 'cindent' works, try the 'smartindent'
- option or 'indentexpr'.
- This option is not used when 'paste' is set.
- NOTE: This option is reset when 'compatible' is set.
-
- *'cinkeys'* *'cink'*
- 'cinkeys' 'cink' string (default "0{,0},0),:,0#,!^F,o,O,e")
- local to buffer
- {not 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 used if 'cindent' is on and 'indentexpr' is
- empty.
- For the format of this option see |cinkeys-format|.
- See |C-indenting|.
-
- *'cinoptions'* *'cino'*
- 'cinoptions' 'cino' string (default "")
- local to buffer
- {not in Vi}
- {not available when compiled without the |+cindent|
- feature}
- The 'cinoptions' affect the way 'cindent' reindents lines in a C
- program. See |cinoptions-values| for the values of this option, and
- |C-indenting| for info on C indenting in general.
-
-
- *'cinwords'* *'cinw'*
- 'cinwords' 'cinw' string (default "if,else,while,do,for,switch")
- local to buffer
- {not 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 {}).
- Note that 'ignorecase' isn't used for 'cinwords'. If case doesn't
- matter, include the keyword both the uppercase and lowercase:
- "if,If,IF".
-
- *'clipboard'* *'cb'*
- 'clipboard' 'cb' string (default "autoselect,exclude:cons\|linux"
- for X-windows, "" otherwise)
- global
- {not in Vi}
- {only in GUI versions or when the |+xterm_clipboard|
- feature is included}
- This option is a list of comma separated names.
- These names are recognized:
-
- unnamed When included, Vim will use the clipboard register '*'
- for all yank, delete, change and put operations which
- would normally go to the unnamed register. When a
- register is explicitly specified, it will always be
- used regardless of whether "unnamed" is in 'clipboard'
- or not. The clipboard register can always be
- explicitly accessed using the "* notation. Also see
- |gui-clipboard|.
-
- autoselect Works like the 'a' flag in 'guioptions': If present,
- then whenever Visual mode is started, or the Visual
- area extended, Vim tries to become the owner of the
- windowing system's global selection or put the
- selected text on the clipboard used by the selection
- register "*. See |guioptions_a| and |quotestar| for
- details. When the GUI is active, the 'a' flag in
- 'guioptions' is used, when the GUI is not active, this
- "autoselect" flag is used.
- Also applies to the modeless selection.
-
- autoselectml Like "autoselect", but for the modeless selection
- only. Compare to the 'A' flag in 'guioptions'.
-
- exclude:{pattern}
- Defines a pattern that is matched against the name of
- the terminal 'term'. If there is a match, no
- connection will be made to the X server. This is
- useful in this situation:
- - Running Vim in a console.
- - $DISPLAY is set to start applications on another
- display.
- - The X server might be terminated while Vim in the
- console is still running, killing Vim.
- To never connect to the X server use: >
- exclude:.*
- < This has the same effect as using the |-X| argument.
- Note that the window title won't be restored as a side
- effect.
- The value of 'magic' is ignored, {pattern} is
- interpreted as if 'magic' was on.
- The rest of the option value will be used for
- {pattern}, this must be the last entry.
-
- *'cmdheight'* *'ch'*
- 'cmdheight' 'ch' number (default 1)
- global
- {not in Vi}
- Number of screen lines to use for the command-line. Helps avoiding
- |hit-enter| prompts.
-
- *'cmdwinheight'* *'cwh'*
- 'cmdwinheight' 'cwh' number (default 7)
- global
- {not in Vi}
- {not available when compiled without the |+vertsplit|
- feature}
- Number of screen lines to use for the command-line window. |cmdwin|
-
- *'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.
- When Vim is running in the GUI or in a resizable window, setting this
- option may cause the window size to be changed.
- When you set this option and Vim is unable to change the physical
- number of columns of the display, the display may be messed up.
-
- *'comments'* *'com'*
- 'comments' 'com' string (default
- "s1:/*,mb:*,ex:*/,://,b:#,:%,:XCOMM,n:>,fb:-")
- local to buffer
- {not in Vi}
- {not available when compiled without the |+comments|
- feature}
- A comma separated list of strings that can start a comment line. See
- |format-comments|. See |option-backslash| about using backslashes to
- insert a space.
-
- *'commentstring'* *'cms'* *E221*
- 'commentstring' 'cms' string (default "/*%s*/")
- local to buffer
- {not in Vi}
- {not available when compiled without the |+folding|

- A template for a comment. The "%s" in the value is replaced with the
- comment text. Currently only used to add markers for folding, see
- |fold-marker|.
-
- *'compatible'* *'cp'* *'nocompatible'* *'nocp'*
- 'compatible' 'cp' boolean (default on, off when a .vimrc file is found)
- global
- {not in Vi}
- This option has the effect of making Vim either more Vi-compatible, or
- make Vim behave in a more useful way.
- This is a special kind of option, because when it's set or reset,
- other options are also changed as a side effect. CAREFUL: Setting or
- resetting this option can have a lot of unexpected effects: Mappings
- are interpreted in another way, undo behaves differently, etc. If you
- set this option in your vimrc file, you should probably put it at the
- very start.
- By default this option is on and the Vi defaults are used for the
- options. This default was chosen for those people who want to use Vim
- just like Vi, and don't even (want to) know about the 'compatible'
- option.
- When a ".vimrc" file is found while Vim is starting up, this option is
- switched off, and all options that have not been modified will be set
- to the Vim defaults. Effectively, this means that when a ".vimrc"
- file exists, Vim will use the Vim defaults, otherwise it will use the
- Vi defaults. (Note: This doesn't happen for the system-wide vimrc
- file). Also see |compatible-default|.
- You can also set this option with the "-C" argument, and reset it with
- "-N". See |-C| and |-N|.
- Switching this option off makes the Vim defaults be used for options
- that have a different Vi and Vim default value. See the options
- marked with a '+' below. Other options are not modified.
- At the moment this option is set, several other options will be set
- or reset to make Vim as Vi-compatible as possible. See the table
- below. This can be used if you want to revert to Vi compatible
- editing.
- See also 'cpoptions'.

-
- *'complete'* *'cpt'*
- 'complete' 'cpt' string (default: ".,w,b,u,t,i")
- local to buffer
- {not in Vi}
- This option specifies how keyword completion |ins-completion| works
- when CTRL-P or CTRL-N are used. It is also used for whole-line
- completion |i_CTRL-X_CTRL-L|. It indicates the type of completion
- and the places to scan. It is a comma separated list of flags:
- . scan the current buffer ('wrapscan' is ignored)
- w scan buffers from other windows
- b scan other loaded buffers that are in the buffer list
- u scan the unloaded buffers that are in the buffer list
- U scan the buffers that are not in the buffer list
- k scan the files given with the 'dictionary' option
- k{dict} scan the file {dict}. Several "k" flags can be given,
- patterns are valid too. For example: >
- :set cpt=k/usr/dict/*,k~/spanish
- < s scan the files given with the 'thesaurus' option
- s{tsr} scan the file {tsr}. Several "s" flags can be given, patterns
- are valid too.
- i scan current and included files
- d scan current and included files for defined name or macro
- |i_CTRL-X_CTRL-D|
- ] tag completion
- t same as "]"
-
- Unloaded buffers are not loaded, thus their autocmds |:autocmd| are
- not executed, this may lead to unexpected completions from some files
- (gzipped files for example). Unloaded buffers are not scanned for
- whole-line completion.
-
- The default is ".,w,b,u,t,i", which means to scan:
- 1. the current buffer
- 2. buffers in other windows
- 3. other loaded buffers
- 4. unloaded buffers
- 5. tags
- 6. included files
-
- As you can see, CTRL-N and CTRL-P can be used to do any 'iskeyword'-
- based expansion (eg dictionary |i_CTRL-X_CTRL-K|, included patterns
- |i_CTRL-X_CTRL-I|, tags |i_CTRL-X_CTRL-]| and normal expansions)
-
- *'confirm'* *'cf'* *'noconfirm'* *'nocf'*
- 'confirm' 'cf' boolean (default off)
- global
- {not in Vi}
- When 'confirm' is on, certain operations that would normally
- fail because of unsaved changes to a buffer, e.g. ":q" and ":e",
- instead raise a |dialog| asking if you wish to save the current
- file(s). You can still use a ! to unconditionally |abandon| a buffer.
- If 'confirm' is off you can still activate confirmation for one
- command only (this is most useful in mappings) with the |:confirm|
- command.
- Also see the |confirm()| function and the 'v' flag in 'guioptions'.
-
- *'conskey'* *'consk'* *'noconskey'* *'noconsk'*
- 'conskey' 'consk' boolean (default off)
- global
- {not in Vi} {only for MS-DOS}
- When on direct console I/O is used to obtain a keyboard character.
- This should work in most cases. Also see |'bioskey'|. Together,
- three methods of console input are available:
- 'conskey' 'bioskey' action ~
- on on or off direct console input
- off on BIOS
- off off STDIN
-
- *'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 behavior. This is used for things where
- not being vi-compatible is mostly or sometimes preferred.
- 'cpoptions' stands for "compatible-options".
- Commas can be added for readability.
- To avoid problems with flags that are added in the future, use the
- "+=" and "-=" feature of ":set" |add-option-flags|.
- NOTE: This option is set to the Vi default value when 'compatible' is
- set and to the Vim default value when 'compatible' is reset.
-
- contains behavior ~
- 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. 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)
- C Do not concatenate sourced lines that start with a
- backslash. See |line-continuation|.
- 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.
- D Can't use CTRL-K to enter a digraph after Normal mode
- commands with a character argument, like |r|, |f| and
- |t|.
- 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.
- i When included, interrupting the reading of a file will
- leave it modified.
- j When joining lines, only add two spaces after a '.',
- not after '!' or '?'. Also see 'joinspaces'.
- J A |sentence| has to be followed by two spaces after
- the '.', '!' or '?'. A <Tab> is not recognized as
- white space.
- k Disable the recognition of raw key codes in
- mappings, abbreviations, and the "to" part of menu
- commands. For example, if <Key> sends ^[OA (where ^[
- is <Esc>), the command ":map X ^[OA" results in X
- being mapped to:
- 'k' included: "^[OA" (3 characters)
- 'k' excluded: "<Key>" (one key code)
- Also see the '<' flag below.
- K Don't wait for a key code to complete when it is
- halfway a mapping. This breaks mapping <F1><F1> when
- only part of the second <F1> has been read. It
- enables cancelling the mapping by typing <F1><Esc>.
- 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',
- 'textwidth' and Virtual replace mode (see |gR|) count
- a <Tab> as two characters, instead of the normal
- behavior 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'|
- n When included, the column used for 'number' will also
- be used for text of wrapped lines.
- o Line offset to search command is not remembered for
- next search.
- O Don't complain if a file is being overwritten, even
- when it didn't exist when editing it. This is a
- protection against a file unexpectedly created by
- someone else. Vi didn't complain about this.
- p Vi compatible Lisp indenting. When not present, a
- slightly better algorithm is used.
- 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', 'fileformat', 'filetype' and
- 'syntax'). This is the (most) Vi compatible setting.
- The options are set to the values in the current
- buffer. When you change an option and go to another
- buffer, the value is copied. Effectively makes the
- buffer options global to all buffers.
-
- 's' 'S' copy buffer options
- no no when buffer created
- yes no when buffer first entered (default)
- X yes each time when buffer entered (vi comp.)
-
- 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 redoing a filter command, use the last used
- external command, whatever it was. Otherwise the last
- used -filter- command is used.
- $ 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.
- % 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.
- * Use ":*" in the same way as ":@". When not included,
- ":*" is an alias for ":'<,'>", select the Visual area.
- < Disable the recognition of special key codes in |<>|
- form in mappings, abbreviations, and the "to" part of
- menu commands. For example, the command
- ":map X <Tab>" results in X being mapped to:
- '<' included: "<Tab>" (5 characters)
- '<' excluded: "^I" (^I is a real <Tab>)
- Also see the 'k' flag above.
-
- *'cscopepathcomp'* *'cspc'*
- 'cscopepathcomp' 'cspc' number (default 0)
- global
- {not available when compiled without the |+cscope|
- feature}
- {not in Vi}
- Determines how many components of the path to show in a list of tags.
- See |cscopepathcomp|.
-
- *'cscopeprg'* *'csprg'*
- 'cscopeprg' 'csprg' string (default "cscope")
- global
- {not available when compiled without the |+cscope|
- feature}
- {not in Vi}
- Specifies the command to execute cscope. See |cscopeprg|.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'cscopetag'* *'cst'* *'nocscopetag'* *'nocst'*
- 'cscopetag' 'cst' boolean (default off)
- global
- {not available when compiled without the |+cscope|
- feature}
- {not in Vi}
- Use cscope for tag commands. See |cscope-options|.
- NOTE: This option is reset when 'compatible' is set.
-
- *'cscopetagorder'* *'csto'*
- 'cscopetagorder' 'csto' number (default 0)
- global
- {not available when compiled without the |+cscope|
- feature}
- {not in Vi}
- Determines the order in which ":cstag" performs a search. See
- |cscopetagorder|.
- NOTE: This option is set to 0 when 'compatible' is set.
-
- *'cscopeverbose'* *'csverb'*
- *'nocscopeverbose'* *'nocsverb'*
- 'cscopeverbose' 'csverb' boolean (default off)
- global
- {not available when compiled without the |+cscope|
- feature}
- {not in Vi}
- Give messages when adding a cscope database. See |cscopeverbose|.
- NOTE: This option is reset when 'compatible' is set.
-
- *'debug'*
- 'debug' string (default "")
- global
- {not in Vi}
- When set to "msg", error messages that would otherwise be omitted will
- be given anyway. This is useful when debugging 'foldexpr' or
- 'indentexpr'.
-
- *'define'* *'def'*
- 'define' 'def' string (default "^#\s*define")
- global or local to buffer |global-local|
- {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 defined name after the match:
- {match with 'define'}{non-ID chars}{defined name}{non-ID char}
- See |option-backslash| about inserting backslashes to include a space
- or backslash.
- The default value is for C programs. For C++ this value would be
- useful, to include const type declarations: >
- ^\(#\s*define\|[a-z]*\s*const\s*[a-z]*\)
- < When using the ":set" command, you need to double the backslashes!
-
- *'delcombine'* *'deco'*
- 'delcombine' 'deco' boolean (default off)
- global
- {not in Vi}
- {only available when compiled with the |+multi_byte|
- feature}
- If editing Unicode and this option is set, backspace and Normal mode
- "x" delete each combining character on its own. When it is off (the
- default) the character along with its combining characters are
- deleted.
-
- This is useful for Hebrew or other languages where one may have
- combining characters overtop of base characters, and want to remove
- only the combining ones.
-
- *'dictionary'* *'dict'*
- 'dictionary' 'dict' string (default "")
- global or local to buffer |global-local|
- {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). Maximum line length is 510 bytes.
- To include a comma in a file name precede it with a backslash. Spaces
- after a comma are ignored, otherwise spaces are included in the file
- name. See |option-backslash| about using backslashes.
- Where to find a list of words?
- - On FreeBSD, there is the file "/usr/share/dict/words".
- - In the Simtel archive, look in the "msdos/linguist" directory.
- - In "miscfiles" of the GNU collection.
- The use of |:set+=| and |:set-=| is preferred when adding or removing
- directories from the list. This avoids problems when a future version
- uses another default.
- Backticks cannot be used in this option for security reasons.
-
- *'diff'* *'nodiff'*
- 'diff' boolean (default off)
- local to window
- {not in Vi}
- {not available when compiled without the |+diff|
- feature}
- Join the current window in the group of windows that shows differences
- between files. See |vimdiff|.
-
- *'dex'* *'diffexpr'*
- 'diffexpr' 'dex' string (default "")
- global
- {not in Vi}
- {not available when compiled without the |+diff|
- feature}
- Expression which is evaluated to obtain an ed-style diff file from two
- versions of a file. See |diff-diffexpr|.
-
- *'dip'* *'diffopt'*
- 'diffopt' 'dip' string (default "filler")
- global
- {not in Vi}
- {not available when compiled without the |+diff|
- feature}
- Option settings for diff mode. It can consist of the following items.
- All are optional. Items must be separated by a comma.
-
- filler Show filler lines, to keep the text
- synchronized with a window that has inserted
- lines at the same position. Mostly useful
- when windows are side-by-side and 'scrollbind'
- is set.
-
- context:{n} Use a context of {n} lines between a change
- and a fold that contains unchanged lines.
- When omitted a context of six lines is used.
- See |fold-diff|.
-
- icase Ignore changes in case of text. "a" and "A"
- are considered the same. Adds the "-i" flag
- to the "diff" command if 'diffexpr' is empty.
-
- iwhite Ignore changes in amount of white space. Adds
- the "-b" flag to the "diff" command if
- 'diffexpr' is empty. Check the documentation
- of the "diff" command for what this does
- exactly. It should ignore adding trailing
- white space, but not leading white space.
-
- Examples: >
-
- :set diffopt=filler,context:4
- :set diffopt=
- :set diffopt=filler
- <
- *'digraph'* *'dg'* *'nodigraph'* *'nodg'*
- 'digraph' 'dg' boolean (default off)
- global
- {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|.
- NOTE: This option is reset when 'compatible' is set.
-
- *'directory'* *'dir'*
- 'directory' 'dir' string (default for Amiga: ".,t:",
- for MS-DOS and Win32: ".,c:\tmp,c:\temp"
- for Unix: ".,~/tmp,/var/tmp,/tmp")
- global
- List of directory names for the swap file, separated with commas.
- - The swap file will be created in the first directory where this is
- possible.
- - Empty means that no swap file will be used (recovery is
- impossible!).
- - A directory "." means to put the swap file in the same directory as
- the edited file. On Unix, a dot is prepended to the file name, so
- it doesn't show in a directory listing.
- - A directory starting with "./" (or ".\" for MS-DOS et.al.) means to
- put the swap file relative to where the edited file is. The leading
- "." is replaced with the path name of the edited file.
- - For Unix and Win32, if a directory ends in two path separators, the
- swap file name will be built from the complete path to the file
- with all path separators substituted to percent '%' signs. This will
- ensure file name uniqueness in the preserve directory.
- - Spaces after the comma are ignored, other spaces are considered part
- of the directory name. To have a space at the start of a directory
- name, precede it with a backslash.
- - To include a comma in a directory name precede it with a backslash.
- - A directory name may end in an ':' or '/'.
- - Environment variables are expanded |:set_env|.
- - Careful with '\' characters, type one before a space, type two to
- get one in the option (see |option-backslash|), for example: >
- :set dir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
- < - For backwards compatibility with Vim version 3.0 a '>' at the start
- of the option is removed.
- Using "." first in the list is recommended. This means that editing
- the same file twice will result in a warning. Using "/tmp" on Unix is
- discouraged: When the system crashes you lose the swap file.
- "/var/tmp" is often not cleared when rebooting, thus is a better
- choice than "/tmp". But it can contain a lot of files, your swap
- files get lost in the crowd. That is why a "tmp" directory in your
- home directory is tried first.
- The use of |:set+=| and |:set-=| is preferred when adding or removing
- directories from the list. This avoids problems when a future version
- uses another default.
- This option cannot be set from a |modeline|, for security reasons.
- {Vi: directory to put temp file in, defaults to "/tmp"}
-
- *'display'* *'dy'*
- 'display' 'dy' string (default "")
- global
- {not in Vi}
- Change the way text is displayed. This is comma separated list of
- flags:
- lastline When included, as much as possible of the last line
- in a window will be displayed. When not included, a
- last line that doesn't fit is replaced with "@" lines.
- uhex Show unprintable characters hexadecimal as <xx>
- instead of using ^C and ~C.
-
- *'eadirection'* *'ead'*
- 'eadirection' 'ead' string (default "both")
- global
- {not in Vi}
- {not available when compiled without the +vertsplit
- feature}
- Tells when the 'equalalways' option applies:
- ver vertically, width of windows is not affected
- hor horizontally, height of windows is not affected
- both width and height of windows is affected
-
- *'ed'* *'edcompatible'* *'noed'* *'noedcompatible'*
- 'edcompatible' 'ed' boolean (default off)
- global
- Makes the 'g' and 'c' flags of the ":substitute" command to be
- toggled each time the flag is given. See |complex-change|. See
- also 'gdefault' option.
- Switching this option on is discouraged!
-
- *'encoding'* *'enc'*
- 'encoding' 'enc' string (default: "latin1" or value from $LANG)
- global
- {only available when compiled with the |+multi_byte|
- feature}
- {not in Vi}
- Sets the character encoding used inside Vim. It applies to text in
- the buffers, registers, Strings in expressions, text stored in the
- viminfo file, etc. It sets the kind of characters which Vim can work
- with. See |encoding-names| for the possible values.
-
- NOTE: Changing this option will not change the encoding of the
- existing text in Vim. It may cause multi-byte text to become invalid.
- It should normally be kept at its default value, or set when Vim
- starts up. See |multibyte|.
-
- The character encoding of files can be different from 'encoding'.
- This is specified with 'fileencoding'. The conversion is done with
- iconv() or as specified with 'charconvert'.
-
- Normally 'encoding' will be equal to your current locale. This will
- be the default if Vim recognizes your environment settings. If
- 'encoding' is not set to the current locale, 'termencoding' must be
- set to convert typed and displayed text. See |encoding-table|.
-
- When you set this option, it fires the |EncodingChanged| autocommand
- event so that you can set up fonts if necessary.
-
- When the option is set, the value is converted to lowercase. Thus
- you can set it with uppercase values too. Underscores are translated
- to '-' signs.
- When the encoding is recognized, it is changed to the standard name.
- For example "Latin-1" becomes "latin1", "ISO_88592" becomes
- "iso-8859-2" and "utf8" becomes "utf-8".
-
- Note: "latin1" is also used when the encoding could not be detected.
- This only works when editing files in the same encoding! When the
- actual characterset is not latin1, make sure 'fileencoding' and
- 'fileencodings' are empty. When conversion is needed, switch to using
- utf-8.
-
- When "unicode", "ucs-2" or "ucs-4" is used, Vim internally uses utf-8.
- You don't notice this while editing, but it does matter for the
- |viminfo-file|. And Vim expects the terminal to use utf-8 too. Thus
- setting 'encoding' to one of these values instead of utf-8 only has
- effect for encoding used for files when 'fileencoding' is empty.
-
- When 'encoding' is set to a Unicode encoding, and 'fileencodings' was
- not set yet, the default for 'fileencodings' is changed.
-
- *'endofline'* *'eol'* *'noendofline'* *'noeol'*
- 'endofline' 'eol' boolean (default on)
- local to buffer
- {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' boolean (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 to the window
- next to it (depending on 'splitbelow' and 'splitright').
- When mixing vertically and horizontally split windows, a minimal size
- is computed and some windows may be larger if there is room. The
- 'eadirection' option tells in which direction the size is affected.
-
- *'equalprg'* *'ep'*
- 'equalprg' 'ep' string (default "")
- global or local to buffer |global-local|
- {not in Vi}
- External program to use for "=" command. When this option is empty
- the internal formatting functions are used ('lisp', 'cindent' or
- 'indentexpr').
- Environment variables are expanded |:set_env|. See |option-backslash|
- about including spaces and backslashes.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'errorbells'* *'eb'* *'noerrorbells'* *'noeb'*
- 'errorbells' 'eb' boolean (default off)
- global
- Ring the bell (beep or screen flash) for error messages. This only
- makes a difference for error messages, the bell will be used always
- for a lot of errors without a message (e.g., hitting <Esc> in Normal
- mode). See 'visualbell' on how to make the bell behave like a beep,
- screen flash or do nothing.
-
- *'errorfile'* *'ef'*
- 'errorfile' 'ef' string (Amiga default: "AztecC.Err",
- others: "errors.err")
- global
- {not 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.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'errorformat'* *'efm'*
- 'errorformat' 'efm' string (default is very long)
- global or local to buffer |global-local|
- {not 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' boolean (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.
- NOTE: This option is set to the Vi default value when 'compatible' is
- set and to the Vim default value when 'compatible' is reset.
-
- *'eventignore'* *'ei'*
- 'eventignore' 'ei' string (default "")
- global
- {not in Vi}
- {not available when compiled without the |+autocmd|
- feature}
- A list of autocommand event names, which are to be ignored.
- When set to "all", all autocommand events are ignored, autocommands
- will not be executed.
- Otherwise this is a comma separated list of event names. Example: >
- :set ei=WinEnter,WinLeave
- <
- *'expandtab'* *'et'* *'noexpandtab'* *'noet'*
- 'expandtab' 'et' boolean (default off)
- local to buffer
- {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|.
- NOTE: This option is reset when 'compatible' is set.
-
- *'exrc'* *'ex'* *'noexrc'* *'noex'*
- 'exrc' 'ex' boolean (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|.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'fileencoding'* *'fenc'* *E213*
- 'fileencoding' 'fenc' string (default: "")
- local to buffer
- {only available when compiled with the |+multi_byte|
- feature}
- {not in Vi}
- Sets the character encoding for the file of this buffer.
- When 'fileencoding' is different from 'encoding', conversion will be
- done when reading and writing the file.
- When 'fileencoding' is empty, the same value as 'encoding' will be
- used (no conversion when reading or writing a file).
- WARNING: Conversion can cause loss of information! When
- 'encoding' is "utf-8" conversion is most likely done in a way
- that the reverse conversion results in the same text. When
- 'encoding' is not "utf-8" some characters may be lost!
- See 'encoding' for the possible values. Additionally, values may be
- specified that can be handled by the converter (either iconv() or
- specified with 'charconvert').
- When reading a file 'fileencoding' will be set from 'fileencodings'.
- To read a file in a certain encoding it won't work by setting
- 'fileencoding', use the |++enc| argument.
- Prepending "8bit-" and "2byte-" has no meaning here, they are ignored.
- When the option is set, the value is converted to lowercase. Thus
- you can set it with uppercase values too. '_' characters are
- replaced with '-'. If a name is recognized from the list for
- 'encoding', it is replaced by the standard name. For example
- "ISO8859-2" becomes "iso-8859-2".
- When this option is set, after starting to edit a file, the 'modified'
- option is set, because the file would be different when written.
- This option can not be changed when 'modifiable' is off.
-
- *'fe'*
- NOTE: Before version 6.0 this option specified the encoding for the
- whole of Vim, this was a mistake. Now use 'encoding' instead. The
- old short name was 'fe', which is no longer used.
-
- *'fileencodings'* *'fencs'*
- 'fileencodings' 'fencs' string (default: "ucs-bom", "ucs-bom,utf-8,latin1"
- when 'encoding' is set to a Unicode value)
- global
- {only available when compiled with the |+multi_byte|
- feature}
- {not in Vi}
- This is a list of character encodings considered when editing a file.
- When a file is read, Vim tries to use the first mentioned character
- encoding. If an error is detected, the next one in the list is tried.
- When an encoding is found that works, 'fileencoding' is set to it.
- If all fail, 'fileencoding' is set to an empty string, which means
- the value of 'encoding' is used.
- WARNING: Conversion can cause loss of information! When
- 'encoding' is "utf-8" (or one of the other Unicode variants)
- conversion is most likely done in a way that the reverse
- conversion results in the same text. When 'encoding' is not
- "utf-8" special characters may be lost!
- The special value "ucs-bom" can be used to check for a Unicode BOM
- (Byte Order Mark) at the start of the file. It must not be preceded
- by "utf-8" or another Unicode encoding for this to work properly.
- If 'fileencodings' is empty, 'fileencoding' is not modified.
- See 'encoding' for the possible values. Additionally, values may be
- specified that can be handled by the converter (either iconv() or
- specified with 'charconvert').
- Old versions of GNU iconv() may cause the conversion to fail (they
- request a very large buffer, more than Vim is willing to provide).
- Try getting another iconv() implementation.
- Unlike 'filecharcode' there is no conversion when the option is set.
-
- *'fileformat'* *'ff'*
- 'fileformat' 'ff' string (MS-DOS, MS-Windows, 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|.
- For the character encoding of the file see 'fileencoding'.
- When 'binary' is set, the value of 'fileformat' is ignored, file I/O
- works like it was set to "unix'.
- This option is set automatically when starting to edit a file and
- 'fileformats' is not empty and 'binary' is off.
- When this option is set, after starting to edit a file, the 'modified'
- option is set, because the file would be different when written.
- This option can not be changed when 'modifiable' is off.
- For backwards compatibility: When this option is set to "dos",
- 'textmode' is set, otherwise 'textmode' is reset.
-
- *'fileformats'* *'ffs'*
- 'fileformats' 'ffs' string (default:
- Vim+Vi MS-DOS, MS-Windows OS/2: "dos,unix",
- Vim Unix: "unix,dos",
- Vim Mac: "mac,unix,dos",
- Vi others: "")
- 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 preferred over "dos".
- 3. If 'fileformats' includes "mac", 'fileformat' is set to "mac".
- This means that "mac" is only chosen when "unix" is not present,
- or when no <NL> is found in the file, and when "dos" is not
- present, or no <CR><NL> is present in the file.
- Also if "unix" was first chosen, but the first <CR> is before
- the first <NL> and there appears to be more <CR>'s than <NL>'s in
- the file, then 'fileformat' is set to "mac".
- 4. If 'fileformat' is still not set, the first name from
- 'fileformats' is used.
- When reading a file into an existing buffer, the same is done, but
- this happens like 'fileformat' has been set appropriately for that
- file only, the option is not changed.
- When 'binary' is set, the value of 'fileformats' is not used.
-
- For systems with a Dos-like <EOL> (<CR><NL>), when reading files that
- are ":source"ed and for vimrc files, automatic <EOL> detection may be
- done:
- - When 'fileformats' is empty, there is no automatic detection. Dos
- format will be used.
- - When 'fileformats' is set to one or more names, automatic detection
- is done. This is based on the first <NL> in the file: If there is a
- <CR> in front of it, Dos format is used, otherwise Unix format is
- used.
- Also see |file-formats|.
- For backwards compatibility: When this option is set to an empty
- string or one format (no comma is included), 'textauto' is reset,
- otherwise 'textauto' is set.
- NOTE: This option is set to the Vi default value when 'compatible' is
- set and to the Vim default value when 'compatible' is reset.
-
- *'filetype'* *'ft'*
- 'filetype' 'ft' string (default: "")
- local to buffer
- {not in Vi}
- {not available when compiled without the |+autocmd|
- feature}
- When this option is set, the FileType autocommand event is triggered.
- All autocommands that match with the value of this option will be
- executed. Thus the value of 'filetype' is used in place of the file
- name.
- Otherwise this option does not always reflect the current file type.
- This option is normally set when the file type is detected. To enable
- this use the ":filetype on" command. |:filetype|
- Setting this option to a different value is most useful in a modeline,
- for a file for which the file type is not automatically recognized.
- Example, for in an IDL file: >
- /* vim: set filetype=idl : */
- < |FileType| |filetypes|
- Do not confuse this option with 'osfiletype', which is for the file
- type that is actually stored with the file.
- This option is not copied to another buffer, independent of the 's' or
- 'S' flag in 'cpoptions'.
-
- *'fillchars'* *'fcs'*
- 'fillchars' 'fcs' string (default "vert:|,fold:-")
- global
- {not in Vi}
- {not available when compiled without the |+windows|
- and |+folding| features}
- Characters to fill the statuslines and vertical separators.
- It is a comma separated list of items:
-
- item default Used for ~
- stl:c ' ' or '^' statusline of the current window
- stlnc:c ' ' or '-' statusline of the non-current windows
- vert:c '|' vertical separators |:vsplit|
- fold:c '-' filling 'foldtext'
- diff:c '-' deleted lines of the 'diff' option
-
- Any one that is omitted will fall back to the default. For "stl" and
- "stlnc" the space will be used when there is highlighting, '^' or '-'
- otherwise.
-
- Example: >
- :set fillchars=stl:^,stlnc:-,vert:\|,fold:-,diff:-
- < This is similar to the default, except that these characters will also
- be used when there is highlighting.
-
- The highlighting used for these items:
- item highlight group ~
- stl:c StatusLine |hl-StatusLine|
- stlnc:c StatusLineNC |hl-StatusLineNC|
- vert:c VertSplit |hl-VertSplit|
- fold:c Folded |hl-Folded|
- diff:c DiffDelete |hl-DiffDelete|
-
- *'fkmap'* *'fk'* *'nofkmap'* *'nofk'*
- 'fkmap' 'fk' boolean (default off) *E198*
- global
- {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 set 'allowrevins' and use CTRL-_ in insert mode to
- toggle this option |i_CTRL-_|. See |farsi.txt|.
-
- *'foldclose'* *'fcl'*
- 'foldclose' 'fcl' string (default "")
- global
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- When set to "all", a fold is closed when the cursor isn't in it and
- its level is higher than 'foldlevel'. Useful if you wants folds to
- automatically close when moving out of them.
-
- *'foldcolumn'* *'fdc'*
- 'foldcolumn' 'fdc' number (default 0)
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- When non-zero, a column with the specified width is shown at the side
- of the window which indicates open and closed folds. The maximum
- value is 12.
- See |folding|.
-
- *'foldenable'* *'fen'* *'nofoldenable'* *'nofen'*
- 'foldenable' 'fen' boolean (default off)
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- When off, all folds are open. This option can be used to quickly
- switch between showing all text unfolded and viewing the text with
- folds (including manually opened or closed folds). It can be toggled
- with the |zi| command. The 'foldcolumn' will remain blank when
- 'foldenable' is off.
- This option is set by commands that create a new fold or close a fold.
- See |folding|.
-
- *'foldexpr'* *'fde'*
- 'foldexpr' 'fde' string (default: "0")
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- or |+eval| feature}
- The expression used for when 'foldmethod' is "expr". It is evaluated
- for each line to obtain its fold level. See |fold-expr|. Also see
- |eval-sandbox|.
-
- *'foldignore'* *'fdi'*
- 'foldignore' 'fdi' string (default: "#")
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- Used only when 'foldmethod' is "indent". Lines starting with
- characters in 'foldignore' will get their fold level from surrounding
- lines. White space is skipped before checking for this character.
- The default "#" works well for C programs. See |fold-indent|.
-
- *'foldlevel'* *'fdl'*
- 'foldlevel' 'fdl' number (default: 0)
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- Sets the fold level: Folds with a higher level will be closed.
- Setting this option to zero will close all folds. Higher numbers will
- close less folds.
- This option is set by commands like |zm|, |zM| and |zR|.
- See |fold-foldlevel|.
-
- *'foldlevelstart'* *'fdls'*
- 'foldlevelstart' 'fdls' number (default: -1)
- global
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- Sets 'foldlevel' when starting to edit another buffer in a window.
- Useful to always start editing with all folds closed (value zero),
- some folds closed (one) or no folds closed (99).
- This is done before reading any modeline, thus a setting in a modeline
- overrules this option. Starting to edit a file for |diff-mode| also
- ignores this option and closes all folds.
- It is also done before BufReadPre autocommands, to allow an autocmd to
- overrule the 'foldlevel' value for specific files.
- When the value is negative, it is not used.
-
- *'foldmarker'* *'fmr'*
- 'foldmarker' 'fmr' string (default: "{{{,}}}")
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- The start and end marker used when 'foldmethod' is "marker". There
- must be one comma, which separates the start and end marker. The
- marker is a literal string (a regular expression would be too slow).
- See |fold-marker|.
-
- *'foldmethod'* *'fdm'*
- 'foldmethod' 'fdm' string (default: "manual")
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- The kind of folding used for the current window. Possible values:
- |fold-manual| manual Folds are created manually.
- |fold-indent| indent Lines with equal indent form a fold.
- |fold-expr| expr 'foldexpr' gives the fold level of a line.
- |fold-marker| marker Markers are used to specify folds.
- |fold-syntax| syntax Syntax highlighting items specify folds.
- |fold-diff| diff Fold text that is not changed.
-
- *'foldminlines'* *'fml'*
- 'foldminlines' 'fml' number (default: 1)
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- Sets the minimum number of screen lines for a fold to be displayed
- closed. Also for manually closed folds.
-
- *'foldnestmax'* *'fdn'*
- 'foldnestmax' 'fdn' number (default: 20)
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- Sets the maximum nesting of folds for the "indent" and "syntax"
- methods. This avoids that too many folds will be created. Using more
- than 20 doesn't work, because the internal limit is 20.
-
- *'foldopen'* *'fdo'*
- 'foldopen' 'fdo' string (default: "block,hor,mark,percent,quickfix,
- search,tag,undo")
- global
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- Specifies for which type of commands folds will be opened, if the
- command moves the cursor into a closed fold. It is a comma separated
- list of items.
- item commands ~
- all any
- block "(", "{", "[[", "[{", etc.
- hor horizontal movements: "l", "w", "fx", etc.
- insert any command in Insert mode
- jump far jumps: "G", "gg", etc.
- mark jumping to a mark: "'m", CTRL-O, etc.
- percent "%"
- quickfix ":cn", ":crew", ":make", etc.
- search search for a pattern: "/", "n", "*", "gd", etc.
- tag jumping to a tag: ":ta", CTRL-T, etc.
- undo undo or redo: "u" and CTRL-R
- When the command is part of a mapping this option is not used. Add
- the |zv| command to the mapping to get the same effect.
- When a movement command is used for an operator (e.g., "dl" or "y%")
- this option is not used. This means the operator will include the
- whole closed fold.
- Note that vertical movements are not here, because it would make it
- very difficult to move onto a closed fold.
- In insert mode the folds containing the cursor will always be open
- when text is inserted.
- To close folds you can re-apply 'foldlevel' with the |zx| command or
- set the 'foldclose' option to "all".
-
- *'foldtext'* *'fdt'*
- 'foldtext' 'fdt' string (default: "foldtext()")
- local to window
- {not in Vi}
- {not available when compiled without the |+folding|
- feature}
- An expression which is used to specify the text displayed for a closed
- fold. See |fold-foldtext|.
-
- *'formatoptions'* *'fo'*
- 'formatoptions' 'fo' string (Vim default: "tcq", Vi default: "vt")
- local to buffer
- {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.
- To avoid problems with flags that are added in the future, use the
- "+=" and "-=" feature of ":set" |add-option-flags|.
- NOTE: This option is set to the Vi default value when 'compatible' is
- set and to the Vim default value when 'compatible' is reset.
-
- *'formatprg'* *'fp'*
- 'formatprg' 'fp' string (default "")
- global
- {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.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'gdefault'* *'gd'* *'nogdefault'* *'nogd'*
- 'gdefault' 'gd' boolean (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
-
- NOTE: This option is reset when 'compatible' is set.
-
- *'grepformat'* *'gfm'*
- 'grepformat' 'gfm' string (default "%f:%l%m,%f %l%m")
- global
- {not in Vi}
- Format to recognize for the ":grep" command output.
- This is a scanf-like string that uses the same format as the
- 'errorformat' option: see |errorformat|.
-
- *'grepprg'* *'gp'*
- 'grepprg' 'gp' string (default "grep -n ",
- Unix: "grep -n $* /dev/null",
- Win32: "findstr /n" or "grep -n",
- VMS: "SEARCH/NUMBERS ")
- global or local to buffer |global-local|
- {not in Vi}
- Program to use for the ":grep" command. This option may contain '%'
- and '#' characters, which are expanded like when used in a command-
- line. The placeholder "$*" is allowed to specify where the arguments
- will be included. Environment variables are expanded |:set_env|. See
- |option-backslash| about including spaces and backslashes.
- When your "grep" accepts the "-H" argument, use this to make ":grep"
- also work well with a single file: >
- :set grepprg=grep\ -nH
- < See also the section |:make_makeprg|, since most of the comments there
- apply equally to 'grepprg'.
- For Win32, the default is "findstr /n" if "findstr.exe" can be found,
- otherwise it's "grep -n".
- This option cannot be set from a |modeline|, for security reasons.
-
- *'guicursor'* *'gcr'*
- 'guicursor' 'gcr' string (default "n-v-c:block-Cursor/lCursor,
- ve:ver35-Cursor,
- o:hor50-Cursor,
- i-ci:ver25-Cursor/lCursor,
- r-cr:hor20-Cursor/lCursor,
- sm:block-Cursor
- -blinkwait175-blinkoff150-blinkon175")
- global
- {not in Vi}
- {only available when compiled with GUI enabled, and
- for MSDOS and Win32 console}
- 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
- ve Visual mode with 'selection' "exclusive" (same as 'v',
- if not specified)
- o Operator-pending mode
- i Insert mode
- r Replace mode
- c Command-line Normal (append) mode
- ci Command-line Insert mode
- cr Command-line Replace mode
- sm showmatch in Insert mode
- a all modes
- The argument-list is a dash separated list of these arguments:
- hor{N} horizontal bar, {N} percent of the character height
- ver{N} vertical bar, {N} percent of the character width
- block block cursor, fills the whole character
- [only one of the above three should be present]
- blinkwait{N} *cursor-blinking*
- blinkon{N}
- blinkoff{N}
- blink times for cursor: blinkwait is the delay before
- the cursor starts blinking, blinkon is the time that
- the cursor is shown and blinkoff is the time that the
- cursor is not shown. The times are in msec. When one
- of the numbers is zero, there is no blinking. The
- default is: "blinkwait700-blinkon400-blinkoff250".
- These numbers are used for a missing entry. This
- means that blinking is enabled by default. To switch
- blinking off you can use "blinkon0". The cursor only
- blinks when Vim is waiting for input, not while
- executing a command.
- To make the cursor blink in an xterm, see
- |xterm-blink|.
- {group-name}
- a highlight group name, that sets the color and font
- for the cursor
- {group-name}/{group-name}
- Two highlight group names, the first is used when
- no language mappings are used, the other when they
- are. |language-mapping|
-
- Examples of parts:
- n-c-v:block-nCursor in Normal, Command-line and Visual mode, use a
- block cursor with colors from the "nCursor"
- highlight group
- i-ci:ver30-iCursor-blinkwait300-blinkon200-blinkoff150
- In Insert and Command-line Insert mode, use a
- 30% vertical bar cursor with colors from the
- "iCursor" highlight group. Blink a bit
- faster.
-
- The 'a' mode is different. It will set the given argument-list for
- all modes. It does not reset anything to defaults. This can be used
- to do a common setting for all modes. For example, to switch off
- blinking: "a:blinkon0"
-
- Examples of cursor highlighting: >
- :highlight Cursor gui=reverse guifg=NONE guibg=NONE
- :highlight Cursor gui=NONE guifg=bg guibg=fg
- <
- In an MSDOS or Win32 console, only the height of the cursor can be
- changed. This can be done by specifying a block cursor, or a
- percentage for a vertical or horizontal cursor.
-
- *'guifont'* *'gfn'* *E235*
- 'guifont' 'gfn' string (default "")
- global
- {not in Vi}
- {only available when compiled with GUI enabled}
- This is a list of fonts which will be used for the GUI version of Vim.
- In its simplest form the value is just one font name. When
- the font cannot be found you will get an error message. To try other
- font names a list can be specified, font names separated with commas.
- The first valid font is used.
- When 'guifontset' is not empty, 'guifont' is not used.
- Spaces after a comma are ignored. To include a comma in a font name
- precede it with a backslash. Setting an option requires an extra
- backslash before a space and a backslash. See also
- |option-backslash|. For example: >
- :set guifont=Screen15,\ 7x13,font\\,with\\,commas
- < will make vim try to use the font "Screen15" first, and if it fails it
- will try to use "7x13" and then "font,with,commas" instead.
- *E236*
- Note that the fonts must be mono-spaced (all characters have the same
- width).
- To preview a font on X11, you might be able to use the "xfontsel"
- program. The "xlsfonts" program gives a list of all available fonts.
- For Win32, GTK and Photon only: >
- :set guifont=*
- < will bring up a font requester, where you can pick the font you want.
- If none of the fonts can be loaded, vim will keep the current setting.
- If an empty font list is given, vim will try using other resource
- settings (for X, it will use the Vim.font resource), and finally it
- will try some builtin default which should always be there ("7x13" in
- the case of X). The font names given should be "normal" fonts. Vim
- will try to find the related bold and italic fonts.
- For the Win32 GUI *E244* *E245*
- - takes these options in the font name:
- hXX - height is XX (points)
- wXX - width is XX (points)
- b - bold
- i - italic
- u - underline
- s - strikeout
- cXX - character set XX. valid charsets are: ANSI, ARABIC,
- BALTIC, CHINESEBIG5, DEFAULT, EASTEUROPE, GB2312, GREEK,
- HANGEUL, HEBREW, JOHAB, MAC, OEM, RUSSIAN, SHIFTJIS,
- SYMBOL, THAI, TURKISH, VIETNAMESE ANSI and BALTIC.
-
- Use a ':' to separate the options.
- - A '_' can be used in the place of a space, so you don't need to use
- backslashes to escape the spaces.
- - Example: >
- :set guifont=courier_new:h12:w5:b:cRUSSIAN
- < Have a look at <http://nova.bsuvc.bsu.edu/prn/monofont/> for
- mono-spaced fonts and comments on them.
- See also |font-sizes|.
-
- *'guifontset'* *'gfs'* *E250* *E252* *E234*
- 'guifontset' 'gfs' string (default "")
- global
- {not in Vi}
- {only available when compiled with GUI enabled and
- with the |+xfontset| feature}
- When not empty, specifies two (or more) fonts to be used. The first
- one for normal English, the second one for your special language. See
- |xfontset|.
- Setting this option also means that all font names will be handled as
- a fontset name. Also the ones used for the "font" argument of the
- |:highlight| command.
- The fonts must match with the current locale. If fonts for the
- character sets that the current locale uses are not included, setting
- 'guifontset' will fail.
- Note the difference between 'guifont' and 'guifontset': In 'guifont'
- the comma-separated names are alternative names, one of which will be
- used. In 'guifontset' the whole string is one fontset name,
- including the commas. It is not possible to specify alternative
- fontset names.
- This example works on many X11 systems: >
- :set guifontset=-*-*-medium-r-normal--16-*-*-*-c-*-*-*
- <
- *'guifontwide'* *'gfw'* *E231*
- 'guifontwide' 'gfw' string (default "")
- global
- {not in Vi}
- {only available when compiled with GUI enabled}
- When not empty, specifies a comma-separated list of fonts to be used
- for double-width characters. The first font that can be loaded is
- used.
- Note: The size of these fonts must be exactly twice as wide as the one
- specified with 'guifont' and the same height.
- Only used when 'encoding' is set to "utf-8" and 'guifontset' is empty
- or invalid.
- When 'guifont' is set and a valid font is found in it and
- 'guifontwide' is empty Vim will attempt to find a matching
- double-width font and set 'guifontwide' to it.
-
- *'guiheadroom'* *'ghr'*
- 'guiheadroom' 'ghr' number (default 50)
- global
- {not in Vi} {only for GTK and X11 GUI}
- The number of pixels subtracted from the screen height when fitting
- the GUI window on the screen. Set this before the GUI is started,
- e.g., in your |gvimrc| file. When zero, the whole screen height will
- be used by the window. When positive, the specified number of pixel
- lines will be left for window decorations and other items on the
- screen. Set it to a negative value to allow windows taller than the
- screen.
-
- *'guioptions'* *'go'*
- 'guioptions' 'go' string (default "gmrLtT" (MS-Windows),
- "agimrLtT" (GTK, Motif and Athena)
- global
- {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.
- To avoid problems with flags that are added in the future, use the
- "+=" and "-=" feature of ":set" |add-option-flags|.
-
- Valid letters are as follows:
- *guioptions_a*
- 'a' Autoselect: If present, then whenever VISUAL mode is started,
- or the Visual area extended, Vim tries to become the owner of
- the windowing system's global selection. This means that the
- Visually highlighted text is available for pasting into other
- applications as well as into Vim itself. When the Visual mode
- ends, possibly due to an operation on the text, or when an
- application wants to paste the selection, the highlighted text
- is automatically yanked into the "* selection register.
- Thus the selection is still available for pasting into other
- applications after the VISUAL mode has ended.
- If not present, then Vim won't become the owner of the
- windowing system's global selection unless explicitly told to
- by a yank or delete operation for the "* register.
- The same applies to the modeless selection.
-
- 'A' Autoselect for the modeless selection. Like 'a', but only
- applies to the modeless selection.
-
- 'guioptions' autoselect Visual autoselect modeless ~
- "" - -
- "a" yes yes
- "A" - yes
- "aA" yes yes
-
- 'f' Foreground: Don't use fork() to detach the GUI from the shell
- where it was started. Use this for programs that wait for the
- editor to finish (e.g., an e-mail program). Alternatively you
- can use "gvim -f" or ":gui -f" to start the GUI in the
- foreground. |gui-fork|
- Note: Set this option in the vimrc file. The forking may have
- happened already when the gvimrc file is read.
-
- 'i' Use a Vim icon. For GTK with KDE it is used in the left-upper
- corner of the window. It's black&white on non-GTK, because of
- limitations of X11. For a color icon, see |X11-icon|.
-
- 'm' Menu bar is present.
- 'M' The system menu "$VIMRUNTIME/menu.vim" is not sourced. Note
- that this flag must be added in the .vimrc file, before
- switching on syntax or filetype recognition (when the .gvimrc
- file is sourced the system menu has already been loaded; the
- ":syntax on" and ":filetype on" commands load the menu too).
- 'g' Grey menu items: Make menu items that are not active grey. If
- 'g' is not included inactive menu items are not shown at all.
- Exception: Athena will always use grey menu items.
-
- 't' Include tearoff menu items. Currently only works for Win32,
- GTK+, and Motif 1.2 GUI.
- 'T' Include Toolbar. Currently only in Win32, GTK+, Motif, and
- Athena GUIs.
-
- 'r' Right-hand scrollbar is always present.
- 'R' Right-hand scrollbar is present when there is a vertically
- split window.
- 'l' Left-hand scrollbar is always present.
- 'L' Left-hand scrollbar is present when there is a vertically
- split window.
- 'b' Bottom (horizontal) scrollbar is present.
-
- And yes, you may even have scrollbars on the left AND the right if
- you really want to :-). See |gui-scrollbars| for more information.
-
- 'v' Use a vertical button layout for dialogs. When not included,
- a horizontal layout is preferred, but when it doesn't fit a
- vertical layout is used anyway.
- 'p' Use Pointer callbacks for X11 GUI. This is required for some
- window managers. If the cursor is not blinking or hollow at
- the right moment, try adding this flag. This must be done
- before starting the GUI. Set it in your gvimrc. Adding or
- removing it after the GUI has started has no effect.
- 'F' Add a footer. Only for Motif. See |gui-footer|.
-
- *'guipty'* *'noguipty'*
- 'guipty' boolean (default on)
- global
- {not in Vi}
- {only available when compiled with GUI enabled}
- Only in the GUI: If on, an attempt is made to open a pseudo-tty for
- I/O to/from shell commands. See |gui-pty|.
-
- *'helpfile'* *'hf'*
- 'helpfile' 'hf' string (default (MSDOS) "$VIMRUNTIME\doc\help.txt"
- (others) "$VIMRUNTIME/doc/help.txt")
- global
- {not in Vi}
- Name of the help file. All help files should be placed together in
- one directory. Environment variables are expanded |:set_env|. For
- example: "$VIMRUNTIME/doc/help.txt". If $VIMRUNTIME is not set, $VIM
- is also tried. Also see |$VIMRUNTIME| and |option-backslash|
- about including spaces and backslashes.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'helpheight'* *'hh'*
- 'helpheight' 'hh' number (default 20)
- global
- {not in Vi}
- {not available when compiled without the +windows
- feature}
- Minimal initial height of the help window when it is opened with the
- ":help" command. The initial height of the help window is half of the
- current window, or (when the 'ea' option is on) the same as other
- windows. When the height is less than 'helpheight', the height is
- set to 'helpheight'. Set to zero to disable.
-
- *'hidden'* *'hid'* *'nohidden'* *'nohid'*
- 'hidden' 'hid' boolean (default off)
- global
- {not in Vi}
- When off a buffer is unloaded when it is |abandon|ed. When on a
- buffer becomes hidden when it is |abandon|ed. If the buffer is still
- displayed in another window, it does not become hidden, of course.
- The commands that move through the buffer list sometimes make a buffer
- hidden although the 'hidden' option is off: When the buffer is
- modified, 'autowrite' is off or writing is not possible, and the '!'
- flag was used. See also |windows.txt|.
- This option is set for one command with ":hide {command}" |:hide|.
- WARNING: It's easy to forget that you have changes in hidden buffers.
- Think twice when using ":q!" or ":qa!".
-
- *'highlight'* *'hl'*
- 'highlight' 'hl' string (default (as a single string):
- "8:SpecialKey,@:NonText,d:Directory,
- e:ErrorMsg,i:IncSearch,l:Search,m:MoreMsg,
- M:ModeMsg,n:LineNr,r:Question,
- s:StatusLine,S:StatusLineNC,c:VertSplit
- t:Title,v:Visual,w:WarningMsg,W:WildMenu,
- f:Folded,F:FoldColumn")
- global
- {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-WildMenu| W wildcard matches displayed for 'wildmenu'
- |hl-Folded| f line used for closed folds
- |hl-FoldColumn| F 'foldcolumn'
-
- The display modes are:
- r reverse (termcap entry "mr" and "me")
- i italic (termcap entry "ZH" and "ZR")
- b bold (termcap entry "md" and "me")
- s standout (termcap entry "so" and "se")
- u underline (termcap entry "us" and "ue")
- n no highlighting
- - no highlighting
- : use a highlight group
- The default is used for occasions that are not included.
- If you want to change what the display modes do, see |dos-colors|
- for an example.
- When using the ':' display mode, this must be followed by the name of
- a highlight group. A highlight group can be used to define any type
- of highlighting, including using color. See |:highlight| on how to
- define one. The default uses a different group for each occasion.
- See |highlight-default| for the default highlight groups.
-
- *'hlsearch'* *'hls'* *'nohlsearch'* *'nohls'*
- 'hlsearch' 'hls' boolean (default off)
- global
- {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' and |:match|.
- When you get bored looking at the highlighted matches, you can turn it
- off with |:nohlsearch|. As soon as you use a search command, the
- highlighting comes back.
- When the search pattern can match an end-of-line, Vim will try to
- highlight all of the matched text. However, this depends on where the
- search starts. This will be the first line in the window or the first
- line below a closed fold. A match in a previous line which is not
- drawn may not continue in an newly drawn line.
- NOTE: This option is reset when 'compatible' is set.
-
- *'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|).
- NOTE: This option is set to the Vi default value when 'compatible' is
- set and to the Vim default value when 'compatible' is reset.
-
- *'hkmap'* *'hk'* *'nohkmap'* *'nohk'*
- 'hkmap' 'hk' boolean (default off)
- global
- {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 set 'allowrevins' and use CTRL-_ in insert mode to
- toggle this option. See |rileft.txt|.
- NOTE: This option is reset when 'compatible' is set.
-
- *'hkmapp'* *'hkp'* *'nohkmapp'* *'nohkp'*
- 'hkmapp' 'hkp' boolean (default off)
- global
- {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 |rileft.txt|.
- NOTE: This option is reset when 'compatible' is set.
-
- *'icon'* *'noicon'*
- 'icon' boolean (default off, on when title can be restored)
- global
- {not in Vi}
- {not available when compiled without the |+title|
- feature}
- When on, the icon text of the window will be set to the value of
- 'iconstring' (if it is not empty), or to the name of the file
- currently being edited. Only the last part of the name is used.
- Overridden by the 'iconstring' option.
- Only works if the terminal supports setting window icons (currently
- only X11 GUI and terminals with a non-empty 't_IS' option - these are
- Unix xterm and iris-ansi by default, where 't_IS' is taken from the
- builtin termcap).
- When Vim was compiled with HAVE_X11 defined, the original icon will be
- restored if possible |X11|. See |X11-icon| for changing the icon on
- X11.
-
- *'iconstring'*
- 'iconstring' string (default "")
- global
- {not in Vi}
- {not available when compiled without the |+title|
- feature}
- When this option is not empty, it will be used for the icon text of
- the window. This happens only when the 'icon' option is on.
- Only works if the terminal supports setting window icon text
- (currently only X11 GUI and terminals with a non-empty 't_IS' option).
- Does not work for MS Windows.
- When Vim was compiled with HAVE_X11 defined, the original icon will be
- restored if possible |X11|.
- When this option contains printf-style '%' items, they will be
- expanded according to the rules used for 'statusline'. See
- 'titlestring' for example settings.
- {not available when compiled without the |+statusline| feature}
-
- *'ignorecase'* *'ic'* *'noignorecase'* *'noic'*
- 'ignorecase' 'ic' boolean (default off)
- global
- Ignore case in search patterns. Also used when searching in the tags
- file.
- Also see 'smartcase'.
- Can be overruled by using "\c" or "\C" in the pattern, see
- |/ignorecase|.
-
- *'imactivatekey'* *'imak'*
- 'imactivatekey' 'imak' string (default "")
- global
- {not in Vi}
- {only available when compiled with |+xim| and
- |+GUI_GTK|}
- Specifies the key that your Input Method in X-Windows uses for
- activation. When this is specified correctly, vim can fully control
- IM with 'imcmdline', 'iminsert' and 'imsearch'.
- You can't use this option to change the activation key, the option
- tells Vim what the key is.
- Format:
- [MODIFIER_FLAG-]KEY_STRING
-
- These characters can be used for MODIFIER_FLAG (case is ignored):
- S Shift key
- L Lock key
- C Control key
- 1 Mod1 key
- 2 Mod2 key
- 3 Mod3 key
- 4 Mod4 key
- 5 Mod5 key
- Combinations are allowed, for example "S-C-space" or "SC-space" are
- both shift+ctrl+space.
- See <X11/keysymdef.h> and XStringToKeysym for KEY_STRING.
-
- Example: >
- :set imactivatekey=S-space
- < "S-space" means shift+space. This is the activation key for kinput2 +
- canna (Japanese), and ami (Korean).
-
- *'imcmdline'* *'imc'* *'noimcmdline'* *'noimc'*
- 'imcmdline' 'imc' boolean (default off)
- global
- {not in Vi}
- {only available when compiled with the |+xim|
- |+multi_byte_ime| or |global-ime| feature}
- When set the Input Method is always on when starting to edit a command
- line, unless entering a search pattern (see 'imsearch' for that).
- Setting this option is useful when your input method allows entering
- English characters directly, e.g., when it's used to type accented
- characters with dead keys.
-
- *'imdisable'* *'imd'* *'nodisable'* *'noimd'*
- 'imdisable' 'imd' boolean (default off, on for some systems (SGI))
- global
- {not in Vi}
- {only available when compiled with the |+xim|
- |+multi_byte_ime| or |global-ime| feature}
- When set the Input Method is never used. This is useful to disable
- the IM when it doesn't work properly.
- Currently this option is on by default for SGI/IRIX machines. This
- may change in later releases.
-
- *'iminsert'* *'imi'*
- 'iminsert' 'imi' number (default 0, 2 when an input method is supported)
- local to buffer
- {not in Vi}
- Specifies whether :lmap or an Input Method (IM) is to be used in
- Insert mode. Valid values:
- 0 :lmap is off and IM is off
- 1 :lmap is ON and IM is off
- 2 :lmap is off and IM is ON
- 2 is available only when compiled with the |+multi_byte_ime|, |+xim|
- or |global-ime|.
- To always reset the option to zero when leaving Insert mode with <Esc>
- this can be used: >
- :inoremap <ESC> <ESC>:set iminsert=0<CR>
- < This makes :lmap and IM turn off automatically when leaving Insert
- mode.
- Note that this option changes when using CTRL-^ in Insert mode
- |i_CTRL-^|.
- The value is set to 1 when defining a new |:lmap| mapping.
- It is also used for the argument of commands like "r" and "f".
- The value 0 may not work correctly with Athena and Motif with some XIM
- methods. Use 'imdisable' to disable XIM then.
-
- *'imsearch'* *'ims'*
- 'imsearch' 'ims' number (default 0, 2 when an input method is supported)
- local to buffer
- {not in Vi}
- Specifies whether :lmap or an Input Method (IM) is to be used when
- entering a search pattern. Valid values:
- -1 the value of 'iminsert' is used, makes it look like
- 'iminsert' is also used when typing a search pattern
- 0 :lmap is off and IM is off
- 1 :lmap is ON and IM is off
- 2 :lmap is off and IM is ON
- Note that this option changes when using CTRL-^ in Insert mode
- |c_CTRL-^|.
- The value is set to 1 when defining a new |:lmap| mapping.
- The value 0 may not work correctly with Athena and Motif with some XIM
- methods. Use 'imdisable' to disable XIM then.
-
- *'include'* *'inc'*
- 'include' 'inc' string (default "^#\s*include")
- global or local to buffer |global-local|
- {not in Vi}
- {not available when compiled without the
- |+find_in_path| feature}
- Pattern to be used to find an include command. It is a search
- pattern, just like for the "/" command (See |pattern|). The default
- value is for C programs. This option is used for the commands "[i",
- "]I", "[d", etc.. The 'isfname' option is used to recognize the file
- name that comes after the matched pattern. See |option-backslash|
- about including spaces and backslashes.
-
- *'includeexpr'* *'inex'*
- 'includeexpr' 'inex' string (default "")
- local to buffer
- {not in Vi}
- {not available when compiled without the
- |+find_in_path| or |+eval| feature}
- Expression to be used to transform the string found with the 'include'
- option to a file name. Mostly useful to change "." to "/" for Java: >
- :set includeexpr=substitute(v:fname,'\\.','/','g')
- < The "v:fname" variable will be set to the file name that was detected.
- Evaluated in the |sandbox|.
- Also used for the |gf| command if an unmodified file name can't be
- found. Allows doing "gf" on the name after an 'include' statement.
- Also used for |<cfile>|.
-
- *'incsearch'* *'is'* *'noincsearch'* *'nois'*
- 'incsearch' 'is' boolean (default off)
- global
- {not 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'.
- NOTE: This option is reset when 'compatible' is set.
-
- *'indentexpr'* *'inde'*
- 'indentexpr' 'inde' string (default "")
- local to buffer
- {not in Vi}
- {not available when compiled without the |+cindent|
- or |+eval| features}
- Expression which is evaluated to obtain the proper indent for a line.
- It is used when a new line is created, for the |=| operator and
- in Insert mode as specified with the 'indentkeys' option.
- When this option is not empty, it overrules the 'cindent' and
- 'smartindent' indenting.
- When 'paste' is set this option is not used for indenting.
- The expression is evaluated with |v:lnum| set to the line number for
- which the indent is to be computed.
- The expression must return the number of spaces worth of indent. It
- can return "-1" to keep the current indent (this means 'autoindent' is
- used for the indent).
- Functions useful for computing the indent are |indent()|, |cindent()|
- and |lispindent()|.
- The evaluation of the expression must not have side effects! It must
- not change the text, jump to another window, etc. Afterwards the
- cursor position is always restored, thus the cursor may be moved.
- Normally this option would be set to call a function: >
- :set indentexpr=GetMyIndent()
- < Error messages will be surpressed, unless the 'debug' option contains
- "msg".
- See |indent-expression|. Also see |eval-sandbox|.
- NOTE: This option is made empty when 'compatible' is set.
-
- *'indentkeys'* *'indk'*
- 'indentkeys' 'indk' string (default "0{,0},:,0#,!^F,o,O,e")
- local to buffer
- {not 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 'indentexpr' isn't empty.
- The format is identical to 'cinkeys', see |indentkeys-format|.
- See |C-indenting| and |indent-expression|.
-
- *'infercase'* *'inf'* *'noinfercase'* *'noinf'*
- 'infercase' 'inf' boolean (default off)
- local to buffer
- {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 lowercase. If the typed text
- has no lowercase letters and the match has a lowercase letter where
- the typed text has an uppercase letter, and there is a letter before
- it, the completed part is made uppercase.
-
- *'insertmode'* *'im'* *'noinsertmode'* *'noim'*
- 'insertmode' 'im' boolean (default off)
- global
- {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. Used for |evim|.
- These Insert mode commands will be useful:
- - Use the cursor keys to move around.
- - Use CTRL-O to execute one Normal mode command |i_CTRL-O|). When
- this is a mapping, it is executed as if 'insertmode' was off.
- Normal mode remains active until the mapping is finished.
- *i_CTRL-L*
- - Use CTRL-L to execute a number of Normal mode commands, then use
- <Esc> to get back to Insert mode.
-
- These items change when 'insertmode' is set:
- - when starting to edit of a file, Vim goes to Insert mode.
- - <Esc> in Insert mode is a no-op and beeps.
- - <Esc> in Normal mode makes Vim go to Insert mode.
- - CTRL-L in Insert mode is a command, it is not inserted.
- - CTRL-Z in Insert mode suspends Vim, see |CTRL-Z|. *i_CTRL-Z*
- However, when <Esc> is used inside a mapping, it behaves like
- 'insertmode' was not set. This was done to be able to use the same
- mappings with 'insertmode' set or not set.
- When executing commands with |:normal| 'insertmode' is not used.
-
- NOTE: This option is reset when 'compatible' is set.
-
- *'isfname'* *'isf'*
- 'isfname' 'isf' string (default for MS-DOS, Win32 and OS/2:
- "@,48-57,/,\,.,-,_,+,,,#,$,%,{,},[,],:,@-@,!,~,="
- for AMIGA: "@,48-57,/,.,-,_,+,,,$,:"
- for VMS: "@,48-57,/,.,-,_,+,,,#,$,%,<,>,[,],:,;,~"
- for OS/390: "@,240-249,/,.,-,_,+,,,#,$,%,~,="
- otherwise: "@,48-57,/,.,-,_,+,,,#,$,%,~,=")
- global
- {not in Vi}
- The characters specified by this option are included in file names and
- path names. Filenames are used for commands like "gf", "[i" and in
- the tags file. It is also used for "\f" in a |pattern|.
- Characters that are defined by the C function isalpha() are also
- always included (this depends on the character set and "locale").
- Multi-byte characters 256 and above are always included, only the
- characters up to 255 are specified with this option.
- For UTF-8 the characters 0xa0 to 0xff are included as well.
-
- Note that on systems using a backslash as path separator, Vim tries to
- do its best to make it work as you would expect. That is a bit
- tricky, since Vi originally used the backslash to escape special
- characters. Vim on will not remove a backslash in front of a normal
- file name character on these systems, but it will on Unix and alikes.
- The '&' and '^' are not included by default, because these are special
- for cmd.exe.
-
- The format of this option is a list of parts, separated with commas.
- Each part can be a single character number or a range. A range is two
- character numbers with '-' in between. A character number can be a
- decimal number between 0 and 255 or the ASCII character itself (does
- not work for digits). Example:
- "_,-,128-140,#-43" (include '_' and '-' and the range
- 128 to 140 and '#' to 43)
- If a part starts with '^', the following character number or range
- will be excluded from the option. The option is interpreted from left
- to right. Put the excluded character after the range where it is
- included. To include '^' itself use it as the last character of the
- option or the end of a range. Example:
- "^a-z,#,^" (exclude 'a' to 'z', include '#' and '^')
- If the character is '@', all characters where isalpha() returns TRUE
- are included. Normally these are the characters a to z and A to Z,
- plus accented characters. To include '@' itself use "@-@". Examples:
- "@,^a-z" All alphabetic characters, excluding lower
- case letters.
- "a-z,A-Z,@-@" All letters plus the '@' character.
- A comma can be included by using it where a character number is
- expected. Example:
- "48-57,,,_" Digits, 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. It is also used for "\i" in a
- |pattern|. See 'isfname' for a description of the format of this
- option.
- Careful: If you change this option, it might break expanding
- environment variables. E.g., when '/' is included and Vim tries to
- expand "$HOME/.viminfo". Maybe you should change 'iskeyword' instead.
-
- *'iskeyword'* *'isk'*
- 'iskeyword' 'isk' string (Vim default for MS-DOS and Win32:
- "@,48-57,_,128-167,224-235"
- otherwise: "@,48-57,_,192-255"
- Vi default: "@,48-57,_")
- local to buffer
- {not in Vi}
- Keywords are used in searching and recognizing with many commands:
- "w", "*", "[i", etc. It is also used for "\k" in a |pattern|. See
- 'isfname' for a description of the format of this option. For C
- programs you could use "a-z,A-Z,48-57,_,.,-,>".
- For a help file it is set to all non-blank printable characters except
- '*', '"' and '|' (so that CTRL-] on a command finds the help for that
- command).
- When the 'lisp' option is on the '-' character is always included.
- NOTE: This option is set to the Vi default value when 'compatible' is
- set and to the Vim default value when 'compatible' is reset.
-
- *'isprint'* *'isp'*
- 'isprint' 'isp' string (default for MS-DOS, Win32, OS/2 and Macintosh:
- "@,~-255"; otherwise: "@,161-255")
- global
- {not in Vi}
- The characters given by this option are displayed directly on the
- screen. It is also used for "\p" in a |pattern|. The characters from
- space (ascii 32) to '~' (ascii 126) are always displayed directly,
- even when they are not included in 'isprint' or excluded. See
- 'isfname' for a description of the format of this option.
-
- Non-printable characters are displayed with two characters:
- 0 - 31 "^@" - "^_"
- 32 - 126 always single characters
- 127 "^?"
- 128 - 159 "~@" - "~_"
- 160 - 254 "| " - "|~"
- 255 "~?"
- When 'encoding' is a Unicode one, illegal bytes from 128 to 255 are
- displayed as <xx>, with the hexadecimal value of the byte.
- When 'display' contains "uhex" all unprintable characters are
- displayed as <xx>.
- The NonText highlighting will be used for unprintable characters.
- |hl-NonText|
-
- Multi-byte characters 256 and above are always included, only the
- characters up to 255 are specified with this option. When a character
- is printable but it is not available in the current font, a
- replacement character will be shown.
- Unprintable and zero-width Unicode characters are displayed as <xxxx>.
- There is no option to specify these characters.
-
- *'joinspaces'* *'js'* *'nojoinspaces'* *'nojs'*
- 'joinspaces' 'js' boolean (default on)
- global
- {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.
- NOTE: This option is set when 'compatible' is set.
-
- *'key'*
- 'key' string (default "")
- local to buffer
- {not in Vi}
- The key that is used for encrypting and decrypting the current buffer.
- See |encryption|.
- Careful: Do not set the key value by hand, someone might see the typed
- key. Use the |:X| command. But you can make 'key' empty: >
- :set key=
- < It is not possible to get the value of this option with ":set key" or
- "echo &key". This is to avoid showing it to someone who shouldn't
- know. It also means you cannot see it yourself once you have set it,
- be careful not to make a typing error!
-
- *'keymap'* *'kmp'*
- 'keymap' 'kmp' string (default "")
- local to buffer
- {not in Vi}
- {only available when compiled with the |+keymap|
- feature}
- Name of a keyboard mapping. See |mbyte-keymap|.
-
- *'keymodel'* *'km'*
- 'keymodel' 'km' string (default "")
- global
- {not in Vi}
- List of comma separated words, which enable special things that keys
- can do. These values can be used:
- startsel Using a shifted special key starts selection (either
- Select mode or Visual mode, depending on "key" being
- present in 'selectmode').
- stopsel Using a not-shifted special key stops selection.
- Special keys in this context are the cursor keys, <End>, <Home>,
- <PageUp> and <PageDown>.
- The 'keymodel' option is set by the |:behave| command.
-
- *'keywordprg'* *'kp'*
- 'keywordprg' 'kp' string (default "man" or "man -s", DOS: "",
- OS/2: "view /", VMS: "help")
- global
- {not in Vi}
- Program to use for the |K| command. Environment variables are
- expanded |:set_env|. When empty ":help" is used.
- When "man" is used, Vim will automatically translate a count for the
- "K" command to a section number. Also for "man -s", in which case the
- "-s" is removed when there is no count.
- See |option-backslash| about including spaces and backslashes.
- Example: >
- :set keywordprg=man\ -s
- < This option cannot be set from a |modeline|, for security reasons.
-
- *'langmap'* *'lmap'* *E357* *E358*
- 'langmap' 'lmap' string (default "")
- global
- {not in Vi}
- {only available when compiled with the |+langmap|
- feature}
- This option allows switching your keyboard into a special language
- mode. When you are typing text in Insert mode the characters are
- inserted directly. When in command mode the 'langmap' option takes
- care of translating these special characters to the original meaning
- of the key. This means you don't have to change the keyboard mode to
- be able to execute Normal mode commands.
- This is the opposite of the 'keymap' option, where characters are
- mapped in Insert mode.
- This only works for 8-bit characters. The value of 'langmap' may be
- specified with multi-byte characters (e.g., UTF-8), but only the lower
- 8 bits of each character will be used.
-
- Example (for Greek): *greek* >
- :set langmap=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!
-
- *'langmenu'* *'lm'*
- 'langmenu' 'lm' string (default "")
- global
- {not in Vi}
- {only available when compiled with the |+menu| and
- |+multi_lang| features}
- Language to use for menu translation. Tells which file is loaded
- from the "lang" directory in 'runtimepath': >
- "lang/menu_" . &langmenu . ".vim"
- < (without the spaces). For example, to always use the Dutch menus, no
- matter what $LANG is set to: >
- :set langmenu=nl_NL.ISO_8859-1
- < When 'langmenu' is empty, |v:lang| is used.
- If your $LANG is set to a non-English language but you do want to use
- the English menus: >
- :set langmenu=none
- < This option must be set before loading menus, switching on filetype
- detection or syntax highlighting. Once the menus are defined setting
- this option has no effect. But you could do this: >
- :source $VIMRUNTIME/delmenu.vim
- :set langmenu=de_DE.ISO_8859-1
- :source $VIMRUNTIME/menu.vim
- < Warning: This deletes all menus that you defined yourself!
-
- *'laststatus'* *'ls'*
- 'laststatus' 'ls' number (default 1)
- global
- {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. |status-line|
-
- *'lazyredraw'* *'lz'* *'nolazyredraw'* *'nolz'*
- 'lazyredraw' 'lz' boolean (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. To force an update use |:redraw|.
-
- *'linebreak'* *'lbr'* *'nolinebreak'* *'nolbr'*
- 'linebreak' 'lbr' boolean (default off)
- local to window
- {not in Vi}
- {not available when compiled without the |+linebreak|
- feature}
- If on Vim will wrap long lines at a character in 'breakat' rather
- than at the last character that fits on the screen. Unlike
- 'wrapmargin' and 'textwidth', this does not insert <EOL>s in the file,
- it only affects the way the file is displayed, not its contents. The
- value of 'showbreak' is used to put in front of wrapped lines. This
- option is not used when the 'wrap' option is off or 'list' is on.
- Note that <Tab> characters after an <EOL> are mostly not displayed
- with the right amount of white space.
-
- *'lines'*
- 'lines' number (default 24 or terminal height)
- global
- Number of lines in the display. Normally you don't need to set this.
- That is done automatically by the terminal initialization code.
- When Vim is running in the GUI or in a resizable window, setting this
- option may cause the window size to be changed.
- When you set this option and Vim is unable to change the physical
- number of lines of the display, the display may be messed up.
-
- *'linespace'* *'lsp'*
- 'linespace' 'lsp' number (default 0, 1 for Win32 GUI)
- global
- {not in Vi}
- {only in the GUI}
- Number of pixel lines inserted between characters. Useful if the font
- uses the full character cell height, making lines touch each other.
- When non-zero there is room for underlining.
-
- *'lisp'* *'nolisp'*
- 'lisp' boolean (default off)
- local to buffer
- {not available when compiled without the |+lispindent|
- feature}
- Lisp mode: When <Enter> is typed in insert mode set the indent for
- the next line to Lisp standards (well, sort of). Also happens with
- "cc" or "S". 'autoindent' must also be on for this to work. The 'p'
- flag in 'cpoptions' changes the method of indenting: Vi compatible or
- better. Also see 'lispwords'.
- The '-' character is included in keyword characters. Redefines the
- "=" operator to use this same indentation algorithm rather than
- calling an external program if 'equalprg' is empty.
- This option is not used when 'paste' is set.
- {Vi: Does it a little bit differently}
-
- *'lispwords'* *'lw'*
- 'lispwords' 'lw' string (default is very long)
- global
- {not in Vi}
- {not available when compiled without the |+lispindent|
- feature}
- Comma separated list of words that influence the Lisp indenting.
-
- *'list'* *'nolist'*
- 'list' boolean (default off)
- local to window
- List mode: Show tabs as CTRL-I, show end of line with $. Useful to
- see the difference between tabs and spaces and for trailing blanks.
- Note that this will also affect formatting (set with 'textwidth' or
- 'wrapmargin') when 'cpoptions' includes 'L'. See 'listchars' for
- changing the way tabs are displayed.
-
- *'listchars'* *'lcs'*
- 'listchars' 'lcs' string (default "eol:$")
- global
- {not in Vi}
- Strings to use in 'list' mode. It is a comma separated list of string
- settings.
- eol:c Character to show at the end of each line. When
- omitted, there is no extra character at the end of the
- line.
- tab:xy Two characters to be used to show a Tab. The first
- char is used once. The second char is repeated to
- fill the space that the Tab normally occupies.
- "tab:>-" will show a Tab that takes four spaces as
- ">---". When omitted, a Tab is show as ^I.
- trail:c Character to show for trailing spaces. When omitted,
- trailing spaces are blank.
- extends:c Character to show in the last column, when 'wrap' is
- off and the line continues beyond the right of the
- screen.
- precedes:c Character to show in the first column, when 'wrap'
- is off and there is text preceeding the character
- visible in the first column.
-
- The characters ':' and ',' cannot be used.
- Examples: >
- :set lcs=tab:>-,trail:-
- :set lcs=tab:>-,eol:<
- :set lcs=extends:>,precedes:<
- < The "NonText" highlighting will be used for "eol", "extends" and
- "precedes". "SpecialKey" for "tab" and "trail".
-
- *'lpl'* *'nolpl'* *'loadplugins'* *'noloadplugins'*
- 'loadplugins' 'lpl' boolean (default on)
- global
- {not in Vi}
- When on the plugin scripts are loaded when starting up |load-plugins|.
- This option can be reset in your |vimrc| file to disable the loading
- of plugins.
- Note that using the "-u NONE" and "--noplugin" command line arguments
- reset this option. |-u| |--noplugin|
-
- *'magic'* *'nomagic'*
- 'magic' boolean (default on)
- global
- Changes the special characters that can be used in search patterns.
- See |pattern|.
- NOTE: To avoid portability problems with using patterns, always keep
- this option at the default "on". Only switch it off when working with
- old Vi scripts. In any other situation write patterns that work when
- 'magic' is on.
-
- *'makeef'* *'mef'*
- 'makeef' 'mef' string (default: "")
- global
- {not in Vi}
- {not available when compiled without the |+quickfix|
- feature}
- Name of the errorfile for the |:make| command (see |:make_makeprg|)
- and the |:grep| command.
- When it is empty, an internally generated temp file will be used.
- When "##" is included, it is replaced by a number to make the name
- unique. This makes sure that the ":make" command doesn't overwrite an
- existing file.
- NOT used for the ":cf" command. See 'errorfile' for that.
- Environment variables are expanded |:set_env|.
- See |option-backslash| about including spaces and backslashes.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'makeprg'* *'mp'*
- 'makeprg' 'mp' string (default "make", VMS: "MMS")
- global or local to buffer |global-local|
- {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. Note that a '|' must be escaped twice: once for ":set"
- and once for the interpretation of a command. When you use a filter
- called "myfilter" do it like this: >
- :set makeprg=gmake\ \\\|\ myfilter
- < The placeholder "$*" can be given (even multiple times) to specify
- where the arguments will be included, for example: >
- :set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*}
- < This option cannot be set from a |modeline|, for security reasons.
-
- *'matchpairs'* *'mps'*
- 'matchpairs' 'mps' string (default "(:),{:},[:]")
- local to buffer
- {not in Vi}
- Characters that form pairs. The |%| command jumps from one to the
- other. Currently only single character pairs are allowed, and they
- must be different. The characters must be separated by a colon. The
- pairs must be separated by a comma. Example for including '<' and '>'
- (HTML): >
- :set mps+=<:>
-
- < A more exotic example, to jump between the '=' and ';' in an
- assignment, useful for languages like C and Java: >
- :au FileType c,cpp,java set mps+==:;
-
- < For a more advanced way of using "%", see the matchit.vim plugin in
- the $VIMRUNTIME/macros directory. |add-local-help|
-
- *'matchtime'* *'mat'*
- 'matchtime' 'mat' number (default 5)
- global
- {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.
-
- *'maxfuncdepth'* *'mfd'*
- 'maxfuncdepth' 'mfd' number (default 100)
- global
- {not in Vi}
- Maximum depth of function calls for user functions. This normally
- catches endless recursion. When using a recursive function with
- more depth, set 'maxfuncdepth' to a bigger number. But this will use
- more memory, there is the danger of failing when memory is exhausted.
- See also |:function|.
-
- *'maxmapdepth'* *'mmd'* *E223*
- 'maxmapdepth' 'mmd' number (default 1000)
- global
- {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 between 256 to 5120 (system
- dependent) or half the amount of memory
- available)
- 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. Maximum value 2000000. Use this to work
- without a limit. Also see 'maxmemtot'.
-
- *'maxmemtot'* *'mmt'*
- 'maxmemtot' 'mmt' number (default between 2048 and 10240 (system
- dependent) or half the amount of memory
- available)
- global
- {not in Vi}
- Maximum amount of memory (in Kbyte) to use for all buffers together.
- Maximum value 2000000. Use this to work without a limit. Also see
- 'maxmem'.
-
- *'menuitems'* *'mis'*
- 'menuitems' 'mis' number (default 25)
- global
- {not in Vi}
- {not available when compiled without the |+menu|
- feature}
- Maximum number of items to use in a menu. Used for menus that are
- generated from a list of items, e.g., the Buffers menu. Changing this
- option has no direct effect, the menu must be refreshed first.
-
- *'modeline'* *'ml'* *'nomodeline'* *'noml'*
- 'modeline' 'ml' boolean (Vim default: on, Vi default: off)
- local to buffer
- *'modelines'* *'mls'*
- 'modelines' 'mls' number (default 5)
- global
- {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|.
- NOTE: 'modeline' is set to the Vi default value when 'compatible' is
- set and to the Vim default value when 'compatible' is reset.
-
- *'modifiable'* *'ma'* *'nomodifiable'* *'noma'*
- 'modifiable' 'ma' boolean (default on)
- local to buffer
- {not in Vi} *E21*
- When off the buffer contents cannot be changed. The 'fileformat' and
- 'fileencoding' options also can't be changed.
- Can be reset with the |-M| command line argument.
-
- *'modified'* *'mod'* *'nomodified'* *'nomod'*
- 'modified' 'mod' boolean (default off)
- local to buffer
- {not in Vi}
- When on, the buffer is considered to be modified. This option is set
- when:
- 1. A change was made to the text since it was last written. Using the
- |undo| command to go back to the original text will reset the
- option. But undoing changes that were made before writing the
- buffer will set the option again, since the text is different from
- when it was written.
- 2. 'fileformat' or 'fileencoding' is different from its original
- value. The original value is set when the buffer is read or
- written. A ":set nomodified" command also resets the original
- values to the current values and the 'modified' option will be
- reset.
- When 'buftype' is "nowrite" or "nofile" this option may be set, but
- will be ignored.
-
- *'more'* *'nomore'*
- 'more' boolean (Vim default: on, Vi default: off)
- global
- {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.
- NOTE: This option is set to the Vi default value when 'compatible' is
- set and to the Vim default value when 'compatible' is reset.
-
- *'mouse'*
- 'mouse' string (default "", "a" for GUI, MS-DOS and Win32)
- global
- {not in Vi}
- Enable the use of the mouse. Only works for certain terminals
- (xterm, MS-DOS, Win32 |win32-mouse|, qnx pterm, and Linux console
- with gpm). For using the mouse in the GUI, see |gui-mouse|.
- The mouse can be enabled for different modes:
- n Normal mode
- v Visual mode
- i Insert mode
- c Command-line mode
- h all previous modes when editing a help file
- a all previous modes
- r for |hit-enter| and |more-prompt| prompt
- Normally you would enable the mouse in all four modes with: >
- :set mouse=a
- < When the mouse is not enabled, the GUI will still use the mouse for
- modeless selection. This doesn't move the text cursor.
-
- See |mouse-using|. Also see |'clipboard'|.
-
- Note: When enabling the mouse in a terminal, copy/paste will use the
- "* register if there is access to an X-server. The xterm handling of
- the mouse buttons can still be used by keeping the shift key pressed.
- Also see the 'clipboard' option.
-
- *'mousefocus'* *'mousef'* *'nomousefocus'* *'nomousef'*
- 'mousefocus' 'mousef' boolean (default off)
- global
- {not in Vi}
- {only works in the GUI}
- The window that the mouse pointer is on is automatically activated.
- When changing the window layout or window focus in another way, the
- mouse pointer is moved to the window with keyboard focus. Off is the
- default because it makes using the pull down menus a little goofy, as
- a pointer transit may activate a window unintentionally.
-
- *'mousehide'* *'mh'* *'nomousehide'* *'nomh'*
- 'mousehide' 'mh' boolean (default on
- global
- {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.
-
- *'mousemodel'* *'mousem'*
- 'mousemodel' 'mousem' string (default "extend", "popup" for MS-DOS and Win32)
- global
- {not in Vi}
- Sets the model to use for the mouse. The name mostly specifies what
- the right mouse button is used for:
- extend Right mouse button extends a selection. This works
- like in an xterm.
- popup Right mouse button pops up a menu. The shifted left
- mouse button extends a selection. This works like
- with Microsoft Windows
- popup_setpos Like "popup", but the cursor will be moved to the
- position where the mouse was clicked, and thus the
- selected operation will act upon the clicked object.
- If clicking inside a selection, that selection will
- be acted upon, ie. no cursor move. This implies of
- course, that right clicking outside a selection will
- end Visual mode.
- Overview of what button does what for each model:
- mouse extend popup(_setpos) ~
- left click place cursor place cursor
- left drag start selection start selection
- shift-left search word extend selection
- right click extend selection popup menu (place cursor)
- right drag extend selection -
- middle click paste paste
-
- In the "popup" model the right mouse button produces a pop-up menu.
- You need to define this first, see |popup-menu|.
-
- Note that you can further refine the meaning of buttons with mappings.
- See |gui-mouse-mapping|. But mappings are NOT used for modeless
- selection (because that's handled in the GUI code directly).
-
- The 'mousemodel' option is set by the |:behave| command.
-
- *'mouseshape'* *'mouses'*
- 'mouseshape' 'mouses' string (default "i:beam,r:beam,s:updown,sd:cross,
- m:no,v:rightup-arrow"
- global
- {not in Vi}
- {only available when compiled with the |+mouseshape|
- feature}
- This option tells Vim what the mouse pointer should look like in
- different modes. The option is a comma separated list of parts, much
- like used for 'guicursor'. Each part consist of a mode/location-list
- and an argument-list:
- mode-list:shape,mode-list:shape,..
- The mode-list is a dash separated list of these modes/locations:
- In a normal window: ~
- n Normal mode
- v Visual mode
- ve Visual mode with 'selection' "exclusive" (same as 'v',
- if not specified)
- o Operator-pending mode
- i Insert mode
- r Replace mode
-
- Others: ~
- c appending to the command-line
- ci inserting in the command-line
- cr replacing in the command-line
- m At the 'Hit ENTER' or 'More' prompts
- e any mode, pointer below last window
- s any mode, pointer on a status line
- sd any mode, while dragging a status line
- vs any mode, pointer on a vertical separator line
- vd any mode, while dragging a vertical separator line
- a everywhere
-
- The shape is one of the following:
- avail name looks like ~
- w x arrow Normal mouse pointer
- w x blank no pointer at all (use with care!)
- w x beam I-beam
- w x updown up-down sizing arrows
- w x leftright left-right sizing arrows
- w x busy The system's usual busy pointer
- w x no The system's usual 'no input' pointer
- x udsizing indicates up-down resizing
- x lrsizing indicates left-right resizing
- x crosshair like a big thin +
- x hand1 white hand
- x hand2 black hand
- x pencil what you write with
- x question big ?
- x rightup-arrow arrow pointing right-up
- w x up-arrow arrow pointing up
- x <number> any X11 pointer number (see X11/cursorfont.h)
-
- The "avail" column contains a 'w' if the shape is available for Win32,
- x for X11.
- Any modes not specifed or shapes not available use the normal mouse
- pointer.
-
- Example: >
- :set mouseshape=s:size,m:no
- < will make the mouse turn to a sizing arrow over the status lines and
- indicate no input when the hit-enter prompt is displayed (since
- clicking the mouse has no effect in this state.)
-
- *'mousetime'* *'mouset'*
- 'mousetime' 'mouset' number (default 500)
- global
- {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.
- alpha if included, single alphabetical characters will be
- incremented or decremented. This is useful for a list with a
- letter index a), b), etc.
- octal if included, numbers that start with a zero will be considered
- to be octal. Example: Using CTRL-A on "007" results in "010".
- hex if included, numbers starting with "0x" or "0X" will be
- considered to be hexadecimal. Example: Using CTRL-X on
- "0x100" results in "0x0ff".
- Numbers which simply begin with a digit in the range 1-9 are always
- considered decimal. This also happens for numbers that are not
- recognized as octal or hex.
-
- *'number'* *'nu'* *'nonumber'* *'nonu'*
- 'number' 'nu' boolean (default off)
- local to window
- Print the line number in front of each line. When the 'n' option is
- excluded from 'cpoptions' a wrapped line will not use the column of
- line numbers (this is the default when 'compatible' isn't set).
- When a long, wrapped line doesn't start with the first character, '-'
- characters are put before the number.
- See |hl-LineNr| for the highlighting used for the number.
-
- *'osfiletype'* *'oft'* *E366*
- 'osfiletype' 'oft' string (RISC-OS default: "Text",
- others default: "")
- local to buffer
- {not in Vi}
- {only available when compiled with the |+osfiletype|
- feature}
- Some operating systems store extra information about files besides
- name, datestamp and permissions. This option contains the extra
- information, the nature of which will vary between systems.
- The value of this option is usually set when the file is loaded, and
- use to set the file type when file is written.
- It can affect the pattern matching of the automatic commands.
- |autocmd-osfiletypes|
-
- *'paragraphs'* *'para'*
- 'paragraphs' 'para' string (default "IPLPPPQPP LIpplpipbp")
- global
- Specifies the nroff macros that separate paragraphs. These are pairs
- of two letters (see |object-motions|).
-
- *'paste'* *'nopaste'*
- 'paste' boolean (default off)
- global
- {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.
- Setting this option is useful when using Vim in a terminal, where Vim
- cannot distinguish between typed text and pasted text. In the GUI, Vim
- knows about pasting and will mostly do the right thing without 'paste'
- being set. The same is true for a terminal where Vim handles the
- mouse clicks itself.
- When the 'paste' option is switched on (also when it was already on):
- - mapping in Insert mode and Command-line mode is disabled
- - abbreviations are disabled
- - 'textwidth' is set to 0
- - 'wrapmargin' is set to 0
- - 'autoindent' is reset
- - 'smartindent' is reset
- - 'softtabstop' is set to 0
- - 'revins' is reset
- - 'ruler' is reset
- - 'showmatch' is reset
- - 'formatoptions' is used like it is empty
- These options keep their value, but their effect is disabled:
- - 'lisp'
- - 'indentexpr'
- - 'cindent'
- NOTE: When you start editing another file while the 'paste' option is
- on, settings from the modelines or autocommands may change the
- settings again, causing trouble when pasting text. You might want to
- set the 'paste' option again.
- When the 'paste' option is reset the mentioned options are restored to
- the value before the moment 'paste' was switched from off to on.
- Resetting 'paste' before ever setting it does not have any effect.
- Since mapping doesn't work while 'paste' is active, you need to use
- the 'pastetoggle' option to toggle the 'paste' option with some key.
-
- *'pastetoggle'* *'pt'*
- 'pastetoggle' 'pt' string (default "")
- global
- {not in Vi}
- When non-empty, specifies the key sequence that toggles the 'paste'
- option. This is like specifying a mapping: >
- :map {keys} :set invpaste<CR>
- < Where {keys} is the value of 'pastetoggle'.
- The difference is that it will work even when 'paste' is set.
- 'pastetoggle' works in Insert mode and Normal mode, but not in
- Command-line mode.
- Mappings are checked first, thus overrule 'pastetoggle'. However,
- when 'paste' is on mappings are ignored in Insert mode, thus you can do
- this: >
- :map <F10> :set paste<CR>
- :map <F11> :set nopaste<CR>
- :imap <F10> <C-O>:set paste<CR>
- :imap <F11> <nop>
- :set pastetoggle=<F11>
- < This will make <F10> start paste mode and <F11> stop paste mode.
- Note that typing <F10> in paste mode inserts "<F10>", since in paste
- mode everything is inserted literally, except the 'pastetoggle' key
- sequence.
-
- *'pex'* *'patchexpr'*
- 'patchexpr' 'pex' string (default "")
- global
- {not in Vi}
- {not available when compiled without the |+diff|
- feature}
- Expression which is evaluated to apply a patch to a file and generate
- the resulting new version of the file. See |diff-patchexpr|.
-
- *'patchmode'* *'pm'* *E206*
- 'patchmode' 'pm' string (default "")
- global
- {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 written a
- copy of the original file will be kept. The name of the copy is the
- name of the original file with the string in the 'patchmode' option
- appended. This option should start with a dot. Use a string like
- ".org". 'backupdir' must not be empty for this to work (Detail: The
- backup file is renamed to the patchmode file after the new file has
- been successfully written, that's why it must be possible to write a
- backup file). If there was no file to be backed up, an empty file is
- created.
- When the 'backupskip' pattern matches, a patchmode file is not made.
- Using 'patchmode' for compressed files appends the extension at the
- end (e.g., "file.gz.orig"), thus the resulting name isn't always
- recognized as a compressed file.
-
- *'path'* *'pa'* *E343* *E345* *E347*
- 'path' 'pa' string (default on Unix: ".,/usr/include,,"
- on OS/2: ".,/emx/include,,"
- other systems: ".,,")
- global or local to buffer |global-local|
- {not in Vi}
- This is a list of directories which will be searched when using the
- |gf|, [f, ]f, ^Wf, |:find| and other commands, provided that the file
- being searched for has a relative path (not starting with '/'). The
- directories in the 'path' option may be relative or absolute.
- - Use commas to separate directory names: >
- :set path=.,/usr/local/include,/usr/include
- < - Spaces can also be used to separate directory names (for backwards
- compatibility with version 3.0). To have a space in a directory
- name, precede it with an extra backslash, and escape the space: >
- :set path=.,/dir/with\\\ space
- < - To include a comma in a directory name precede it with an extra
- backslash: >
- :set path=.,/dir/with\\,comma
- < - To search relative to the directory of the current file, use: >
- :set path=.
- < - To search in the current directory use an empty string between two
- commas: >
- :set path=,,
- < - A directory name may end in a ':' or '/'.
- - Environment variables are expanded |:set_env|.
- - When using |netrw.vim| URLs can be used. For example, adding
- "http://www.vim.org" will make ":find index.html" work.
- - Search upwards and downwards in a directory tree:
- 1) "*" matches a sequence of characters, e.g.: >
- :set path=/usr/include/*
- < means all subdirectories in /usr/include (but not /usr/include
- itself). >
- :set path=/usr/*c
- < matches /usr/doc and /usr/src.
- 2) "**" matches a subtree, up to 100 directories deep. Example: >
- :set path=/home/user_x/src/**
- < means search in the whole subtree under "/home/usr_x/src".
- 3) If the path ends with a ';', this path is the startpoint
- for upward search.
- See |file-searching| for more info and exact syntax.
- {not available when compiled without the |+path_extra| feature}
- - Careful with '\' characters, type two to get one in the option: >
- :set path=.,c:\\include
- < Or just use '/' instead: >
- :set path=.,c:/include
- < Don't forget "." or files won't even be found in the same directory as
- the file!
- The maximum length is limited. How much depends on the system, mostly
- it is something like 256 or 1024 characters.
- You can check if all the include files are found, using the value of
- 'path', see |:checkpath|.
- The use of |:set+=| and |:set-=| is preferred when adding or removing
- directories from the list. This avoids problems when a future version
- uses another default. To remove the current directory use: >
- :set path-=
- < To add the current directory use: >
- :set path+=
- < To use an environment variable, you probably need to replace the
- separator. Here is an example to append $INCL, in which directory
- names are separated with a semi-colon: >
- :let &path = &path . "," . substitute($INCL, ';', ',', 'g')
- < Replace the ';' with a ':' or whatever separator is used. Note that
- this doesn't work when $INCL contains a comma or white space.
-
- *'previewheight'* *'pvh'*
- 'previewheight' 'pvh' number (default 12)
- global
- {not in Vi}
- {not available when compiled without the |+windows| or
- |+quickfix| feature}
- Default height for a preview window. Used for |:ptag| and associated
- commands. Used for |CTRL-W_}| when no count is given.
-
- *'previewwindow'* *'nopreviewwindow'* *'pvw'* *'nopvw'*
- 'previewwindow' 'pvw' boolean (default off)
- local to window
- {not in Vi}
- {not available when compiled without the |+windows| or
- |+quickfix| feature}
- Identifies the preview window. Only one window can have this option
- set. It's normally not set directly, but by using one of the commands
- |:ptag|, |:pedit|, etc.
-
- *'printdevice'* *'pdev'*
- 'printdevice' 'pdev' string (default empty)
- global
- {not in Vi}
- {only available when compiled with the |+printer|
- feature}
- This defines the name of the printer to be used when the |:hardcopy|
- command is issued with a bang (!) to skip the printer selection
- dialog. On Win32, it should be the printer name exactly as it appears
- in the standard printer dialog.
- If the option is empty, then vim will use the system default printer
- for ":hardcopy!"
-
- *'printexpr'* *'pexpr'*
- 'printexpr' 'pexpr' String (default: see below)
- global
- {not in Vi}
- {only available when compiled with the |+printer|
- and |+postscript| features}
- Expression that is evaluated to print the PostScript produced with
- ":hardcopy".
- The file name to be printed is in |v:fname_in|.
- The arguments to the ":hardcopy" command are in |v:cmdarg|.
- The expression must take care of deleting the file after printing it.
- When there is an error, the expression must return a non-zero number.
- If there is no error, return zero or an empty string.
- The default for non MS-Windows or VMS systems is to simply use "lpr"
- to print the file: >
-
- system('lpr' . (&printdevice == '' ? '' : ' -P' . &printdevice)
- . ' ' . v:fname_in) . delete(v:fname_in) + v:shell_error
- <
- On MS-Windows machines the default is to copy the file to the
- currently specified printdevice: >
-
- system('copy' . ' ' . v:fname_in . ' ' &printdevice)
- . delete(v:fname_in)
- <
- On VMS machines the default is to send the file to either the default
- or currently specified printdevice: >
-
- system('print' . (&printdevice == '' ? '' : ' /queue=' .
- &printdevice) . ' ' . v:fname_in) . delete(v:fname_in)
- <
- If you change this option, using a function is an easy way to avoid
- having to escape all the spaces. Example: >
-
- :set printexpr=PrintFile(v:fname_in)
- :function PrintFile(fname)
- : call system("ghostview " . a:fname)
- : call delete(a:fname)
- : return v:shell_error
- :endfunc
-
- < Be aware that some print programs return control before they have read
- the file. If you delete the file too soon it will not be printed.
- These programs usually offer an option to have them remove the file
- when printing is done.
- *E365*
- If evaluating the expression fails or it results in a non-zero number,
- you get an error message. In that case Vim will delete the
- file. In the default value for non-MS-Windows a trick is used: Adding
- "v:shell_error" will result in a non-zero number when the system()
- call fails.
- This option cannot be set from a |modeline|, for security reasons.
-
- *'printfont'* *'pfn'*
- 'printfont' 'pfn' string (default "courier")
- global
- {not in Vi}
- {only available when compiled with the |+printer|
- feature}
- This is the name of the font that will be used for the |:hardcopy|
- command's output. It has the same format as the 'guifont' option,
- except that only one font may be named, and the special "guifont=*"
- syntax is not available.
- In the Win32 GUI version this specifies a font name with its extra
- attributes, as with the 'guifont' option.
- For other systems, only ":h11" is recognized, where "11" is the point
- size of the font. When omitted, the points size is 10.
-
- *'printheader'* *'pheader'*
- 'printheader' 'pheader' string (default "%<%f%h%m%=Page %N")
- global
- {not in Vi}
- {only available when compiled with the |+printer|
- feature}
- This defines the format of the header produced in |:hardcopy| output.
- The option is defined in the same way as the 'statusline' option.
- If Vim has not been compiled with the |+statusline| feature, this
- option has no effect and a simple default header is used, which shows
- the page number.
-
- *'printoptions'* *'popt'*
- 'printoptions' 'popt' string (default "")
- global
- {not in Vi}
- {only available when compiled with |+printer| feature}
- This is a comma-separated list of items that control the format of
- the output of |:hardcopy|:
-
- left:{spec} left margin (default: 10pc)
- right:{spec} right margin (default: 5pc)
- top:{spec} top margin (default: 5pc)
- bottom:{spec} bottom margin (default: 5pc)
- {spec} is a number followed by "in" for
- inches, "pt" for points (1 point is 1/72 of an
- inch), "mm" for millimetres or "pc" for a
- percentage of the media size.
- Weird example:
- left:2in,top:30pt,right:16mm,bottom:3pc
- If the unit is not recognized there is no
- error and the default value is used.
-
- header:{nr} Number of lines to reserve for the header.
- Only the first line is actually filled, thus
- when {nr} is 2 there is one empty line. The
- header is formatted according to
- 'printheader'.
- header:0 Do not print a header.
- header:2 (default) Use two lines for the header
-
- syntax:n Do not use syntax highlighting. This is
- faster and thus useful when printing large
- files.
- syntax:y Do syntax highlighting.
- syntax:a (default) Use syntax highlighting if the printer appears
- to be able to print color or grey.
-
- number:y Include line numbers in the printed output.
- number:n (default) No line numbers.
-
- wrap:y (default) Wrap long lines.
- wrap:n Truncate long lines.
-
- duplex:off Print on one side.
- duplex:long (default) Print on both sides (when possible), bind on
- long side.
- duplex:short Print on both sides (when possible), bind on
- short side.
-
- collate:y (default) Collating: 1 2 3, 1 2 3, 1 2 3
- collate:n No collating: 1 1 1, 2 2 2, 3 3 3
-
- jobsplit:n (default) Do all copies in one print job
- jobsplit:y Do each copy as a separate print job. Useful
- when doing N-up postprocessing.
-
- portrait:y (default) Orientation is portrait.
- portrait:n Orientation is landscape.
-
-
- paper:A4 (default) Paper size: A4
- paper:{name} Paper size from this table:
- {name} size in inch ~
- 10x14 10 x 14
- A3 11.69 x 16.54
- A4 8.27 x 11.69
- A5 5.83 x 8.27
- B4 10.12 x 14.33
- B5 7.17 x 10.12
- executive 7.25 x 10.5
- folio 8.27 x 13
- ledger 17 x 11
- legal 8.5 x 14
- letter 8.5 x 11
- quarto 8.5 x 10.83
- statement 5.5 x 8.5
- tabloid 11 x 17
-
- The item indicated with (default) is used when the item is not
- present. The values are not always used, especially when using a
- dialog to select the printer and options.
- Example: >
- :set printoptions=paper:letter,duplex:off
- <
- *'readonly'* *'ro'* *'noreadonly'* *'noro'*
- 'readonly' 'ro' boolean (default off)
- local to buffer
- {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' boolean (default on)
- global
- Allows for mappings to work recursively. If you do not want this for
- a single entry, use the :noremap[!] command.
-
- *'report'*
- 'report' number (default 2)
- global
- Threshold for reporting number of lines changed. When the number of
- changed lines is more than 'report' a message will be given for most
- ":" commands. If you want it always, set 'report' to 0.
- For the ":substitute" command the number of substitutions is used
- instead of the number of lines.
-
- *'restorescreen'* *'rs'* *'norestorescreen'* *'nors'*
- 'restorescreen' 'rs' boolean (default on)
- global
- {not in Vi} {Windows 95/NT console 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' boolean (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-_
- command in Insert mode, when 'allowrevins' is set.
- NOTE: This option is reset when 'compatible' or 'paste' is set.
-
- *'rightleft'* *'rl'* *'norightleft'* *'norl'*
- 'rightleft' 'rl' boolean (default off)
- local to window
- {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 appear from the right to the left. Using
- this option, it is possible to edit files for languages that are
- written from the right to the left such as Hebrew and Arabic. This
- option is per window, so it is possible to edit mixed files
- simultaneously, or to view the same file in both ways (this is
- sometimes useful when editing Hebrew TeX--XeT files). See
- |rileft.txt|.
-
- *'ruler'* *'ru'* *'noruler'* *'noru'*
- 'ruler' 'ru' boolean (default off)
- global
- {not in Vi}
- {not available when compiled without the
- |+cmdline_info| feature}
- Show the line and column number of the cursor position, separated by a
- comma. When there is room, the relative position of the displayed
- text in the file is shown on the far right:
- Top first line is visible
- Bot last line is visible
- All first and last line are visible
- 45% relative position in the file
- If 'rulerformat' is set, it will determine the contents of the ruler.
- Each window has its own ruler. If a window has a status line, the
- ruler is shown there. Otherwise it is shown in the last line of the
- screen. If the statusline is given by 'statusline' (ie. not empty),
- this option takes precedence over 'ruler' and 'rulerformat'
- If the number of characters displayed is different from the number of
- bytes in the text (e.g., for a TAB or a multi-byte character), both
- the text column (byte number) and the screen column are shown,
- separated with a dash.
- For an empty line "0-1" is shown.
- For an empty buffer the line number will also be zero: "0,0-1".
- This option is reset when the 'paste' option is set.
- If you don't want to see the ruler all the time but want to know where
- you are, use "g CTRL-G" |g_CTRL-G|.
- NOTE: This option is reset when 'compatible' is set.
-
- *'rulerformat'* *'ruf'*
- 'rulerformat' 'ruf' string (default empty)
- global
- {not in Vi}
- {not available when compiled without the |+statusline|
- feature}
- When this option is not empty, it determines the content of the ruler
- string, as displayed for the 'ruler' option.
- The format of this option, is like that of 'statusline'.
- The default ruler width is 17 characters. To make the ruler 15
- characters wide, put "%15(" at the start and "%)" at the end.
- Example: >
- :set rulerformat=%15(%c%V\ %p%%%)
- <
- *'runtimepath'* *'rtp'*
- 'runtimepath' 'rtp' string (default:
- Unix: "$HOME/.vim,
- $VIM/vimfiles,

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