{expr}) abs(){expr}. When {expr} evaluates to
a Float abs() returns a Float. When {expr} can be
converted to a Number abs() returns a Number. Otherwise
abs() gives an error message and returns -1.
Examples:echo abs(1.456)echo abs(-5.456)echo abs(-4){expr} (number)
number){expr}) acos(){expr} measured in radians, as a
Float in the range of [0, pi].
{expr} must evaluate to a Float or a Number in the range
[-1, 1].
Returns NaN if {expr} is outside the range [-1, 1]. Returns
0.0 if {expr} is not a Float or a Number.
Examples:echo acos(0)echo acos(-0.5){expr} (number)
number){object}, {expr}) add(){expr} to List or Blob {object}. Returns
the resulting List or Blob. Examples:let alist = add([1, 2, 3], item)
call add(mylist, "woodstock"){expr} is a List it is appended as a single
item. Use extend() to concatenate Lists.
When {object} is a Blob then {expr} must be a number.
Use insert() to add an item at another position.
Returns 1 if {object} is not a List or a Blob.{object} (any)

integer)lua vim.print(vim.fn.api_info())table){lnum}, {text}) append(){text} is a List: Append each item of the List as a
text line below line {lnum} in the current buffer.
Otherwise append {text} as one text line below line {lnum} in
the current buffer.
Any type of item is accepted and converted to a String.
{lnum} can be zero to insert a line before the first one.
{lnum} is used like with getline().
Returns 1 for failure ({lnum} out of range or out of memory),
0 for success. When {text} is an empty list zero is returned,
no matter the value of {lnum}. Example:let failed = append(line('$'), "# THE END")
let failed = append(0, ["Chapter 1", "the beginning"]){lnum} (integer)
{text} (string|string[])
0|1){buf}, {lnum}, {text}) appendbufline(){expr}.{buf}, see bufname().{lnum} is the line number to append below. Note that using
line() would use the current buffer, not the one appending
to. Use "$" to append at the end of the buffer. Other string
values are not supported.{buf} is not a valid buffer or {lnum} is not valid, an
error message is given. Example:let failed = appendbufline(13, 0, "# THE START"){text} is an empty list then no error is given
for an invalid {lnum}, since {lnum} isn't actually used.{buf} (integer|string)

0|1){winid}]) argc(){winid} is not supplied, the argument list of the current
window is used.
If {winid} is -1, the global argument list is used.
Otherwise {winid} specifies the window of which the argument
list is used: either the window number or the window ID.
Returns -1 if the {winid} argument is invalid.{winid} (integer?)
integer)integer){winnr} [, {tabnr}]]) arglistid(){winnr} only use this window in the current tab page.
With {winnr} and {tabnr} use the window in the specified tab
page.
{winnr} can be the window number or the window-ID.{winnr} (integer?)
{tabnr} (integer?)
integer){nr} [, {winid}]]) argv(){nr}th file in the argument list. See
arglist. "argv(0)" is the first one. Example:let i = 0
while i < argc()
let f = escape(fnameescape(argv(i)), '.')
exe 'amenu Arg.' .. f .. ' :e ' .. f .. '<CR>'
let i = i + 1
endwhile{winid} argument specifies the window ID, see argc().
For the Vim command line arguments see v:argv.{nr}th argument is not present in
the argument list. Returns an empty List if the {winid}
argument is invalid.{nr} (integer?)

string|string[]){expr}) asin(){expr} measured in radians, as a Float
in the range of [-pi/2, pi/2].
{expr} must evaluate to a Float or a Number in the range
[-1, 1].
Returns NaN if {expr} is outside the range [-1, 1]. Returns
0.0 if {expr} is not a Float or a Number.
Examples:echo asin(0.8)echo asin(-0.5){expr} (any)

0|1){expected}, {actual} [, {msg}]) assert_equal(){expected} and {actual} are not equal an error message is
added to v:errors and 1 is returned. Otherwise zero is
returned. assert-return
The error is in the form "Expected {expected} but got
{actual}". When {msg} is present it is prefixed to that,
along with the location of the assert when run from a script.call assert_equal('foo', 'bar', 'baz'){expected} (any)

0|1){fname_one}, {fname_two}) assert_equalfile(){fname_one} and {fname_two} do not contain
exactly the same text an error message is added to v:errors.
Also see assert-return.
When {fname_one} or {fname_two} does not exist the error will
mention that.{fname_one} (string)
{fname_two} (string)
0|1){error} [, {msg}]) assert_exception(){error} an error
message is added to v:errors. Also see assert-return.
This can be used to assert that a command throws an exception.
Using the error number, followed by a colon, avoids problems
with translations:try
commandthatfails
call assert_false(1, 'command should have failed')
catch
call assert_exception('E492:')
endtry{error} (any)
{msg} (any?)
0|1){cmd} [, {error} [, {msg} [, {lnum} [, {context}]]]])
Run {cmd} and add an error message to v:errors if it does
NOT produce an error or when {error} is not found in the
error message. Also see assert-return.{error} is a string it must be found literally in the
first reported error. Most often this will be the error code,
including the colon, e.g. "E123:".call assert_fails('bad cmd', 'E987:'){error} is a List with one or two strings, these are
used as patterns. The first pattern is matched against the
first reported error:call assert_fails('cmd', ['E987:.*expected bool'])call assert_fails('cmd', ['', 'E987:']){msg} is empty then it is not used. Do this to get the
default message when passing the {lnum} argument.
E1115 {lnum} is present and not negative, and the {error}
argument is present and matches, then this is compared with
the line number at which the error was reported. That can be
the line number in a function or in a script.
E1116 {context} is present it is used as a pattern and matched
against the context (script name or function name) where
{lnum} is located in.{cmd} (string)

0|1){actual} [, {msg}]) assert_false(){actual} is not false an error message is added to
v:errors, like with assert_equal().
The error is in the form "Expected False but got {actual}".
When {msg} is present it is prefixed to that, along with the
location of the assert when run from a script.
Also see assert-return.{actual} is not a
number the assert fails.{actual} (any)

0|1){pattern}, {actual} [, {msg}]) assert_match(){pattern} does not match {actual} an error message is
added to v:errors. Also see assert-return.
The error is in the form "Pattern {pattern} does not match
{actual}". When {msg} is present it is prefixed to that,
along with the location of the assert when run from a script.{pattern} is used as with expr-=~: The matching is always done
like 'magic' was set and 'cpoptions' is empty, no matter what
the actual value of 'magic' or 'cpoptions' is.{actual} is used as a string, automatic conversion applies.
Use "^" and "$" to match with the start and end of the text.
Use both to match the whole text.call assert_match('^f.*o$', 'foobar'){pattern} (string)
{actual} (string)
{msg} (string?)
0|1){cmd}) assert_nobeep(){cmd} and add an error message to v:errors if it
produces a beep or visual bell.
Also see assert_beeps().{cmd} (string)

v:errors, like with assert_equal().
Also see assert-return.
A value is TRUE when it is a non-zero number or v:true.
When {actual} is not a number or v:true the assert fails.
When {msg} is given it is prefixed to the default message,
along with the location of the assert when run from a script.{actual} (any)

0|1){expr}) atan(){expr}, in
the range [-pi/2, +pi/2] radians, as a Float.
{expr} must evaluate to a Float or a Number.
Returns 0.0 if {expr} is not a Float or a Number.
Examples:echo atan(100)echo atan(-4.01){expr} (number)
number){expr1}, {expr2}) atan2(){expr1} / {expr2}, measured in
radians, as a Float in the range [-pi, pi].
{expr1} and {expr2} must evaluate to a Float or a Number.
Returns 0.0 if {expr1} or {expr2} is not a Float or a
Number.

0|1){name}) bufadd(){name} (must be a
String).
If a buffer for file {name} already exists, return that buffer
number. Otherwise return the buffer number of the newly
created buffer. When {name} is an empty string then a new
buffer is always created.
The buffer will not have 'buflisted' set and not be loaded
yet. To add some text to the buffer use this:let bufnr = bufadd('someName')
call bufload(bufnr)
call setbufline(bufnr, 1, ['some', 'text']){name} (string)
integer){buf}) bufexists(){buf} exists.
If the {buf} argument is a number, buffer numbers are used.
Number zero is the alternate buffer for the current window.{buf} argument is a string it must match a buffer name
exactly. The name can be:
{buf} (any)
0|1){buf}) buflisted(){buf} exists and is listed (has the 'buflisted' option set).
The {buf} argument is used like with bufexists().{buf} (any)
0|1){buf}) bufload(){buf} is loaded. When the buffer name
refers to an existing file then the file is read. Otherwise
the buffer will be empty. If the buffer was already loaded
then there is no change. If the buffer is not related to a
file then no file is read (e.g., when 'buftype' is "nofile").
If there is an existing swap file for the file of the buffer,
there will be no dialog, the buffer will be loaded anyway.
The {buf} argument is used like with bufexists().{buf} (any)
{buf}) bufloaded(){buf} exists and is loaded (shown in a window or hidden).
The {buf} argument is used like with bufexists().{buf} (any)
0|1){buf}]) bufname():ls command, but not using special names such as
"[No Name]".
If {buf} is omitted the current buffer is used.
If {buf} is a Number, that buffer number's name is given.
Number zero is the alternate buffer for the current window.
If {buf} is a String, it is used as a file-pattern to match
with the buffer names. This is always done like 'magic' is
set and 'cpoptions' is empty. When there is more than one
match an empty string is returned.
"" or "%" can be used for the current buffer, "#" for the
alternate buffer.
A full match is preferred, otherwise a match at the start, end
or middle of the buffer name is accepted. If you only want a
full match then put "^" at the start and "$" at the end of the
pattern.
Listed buffers are found first. If there is a single match
with a listed buffer, that one is returned. Next unlisted
buffers are searched for.
If the {buf} is a String, but you want to use it as a buffer
number, force it to be a Number by adding zero to it:echo bufname("3" + 0)echo bufname("#") " alternate buffer name
echo bufname(3) " name of buffer 3
echo bufname("%") " name of current buffer
echo bufname("file2") " name of buffer where "file2" matches.{buf} (integer|string?)
string){buf} [, {create}]]) bufnr():ls command. For the use of {buf}, see bufname()
above.
If the buffer doesn't exist, -1 is returned. Or, if the
{create} argument is present and TRUE, a new, unlisted,
buffer is created and its number is returned.
bufnr("$") is the last buffer:let last_buffer = bufnr("$"){buf} (integer|string?)
{create} (any?)
integer){buf}) bufwinid(){buf}. For the use of {buf},
see bufname() above. If buffer {buf} doesn't exist or
there is no such window, -1 is returned. Example:echo "A window containing buffer 1 is " .. (bufwinid(1)){buf} (any)
integer){buf}) bufwinnr(){buf} doesn't exist or there is no such window, -1
is returned. Example:echo "A window containing buffer 1 is " .. (bufwinnr(1)){buf} (any)
integer){byte}) byte2line(){byte} in the current buffer. This includes the
end-of-line character, depending on the 'fileformat' option
for the current buffer. The first character has byte count
one.
Also see line2byte(), go and :goto.{byte} value is invalid.{byte} (any)
integer){expr}, {nr} [, {utf16}]) byteidx(){nr}th character in the String
{expr}. Use zero for the first character, it then returns
zero.
If there are no multibyte characters the returned value is
equal to {nr}.
Composing characters are not counted separately, their byte
length is added to the preceding base character. See
byteidxcomp() below for counting composing characters
separately.
When {utf16} is present and TRUE, {nr} is used as the UTF-16
index in the String {expr} instead of as the character index.
The UTF-16 index is the index in the string when it is encoded
with 16-bit words. If the specified UTF-16 index is in the
middle of a character (e.g. in a 4-byte character), then the
byte index of the first byte in the character is returned.
Refer to string-offset-encoding for more information.
Example :echo matchstr(str, ".", byteidx(str, 3))let s = strpart(str, byteidx(str, 3))
echo strpart(s, 0, byteidx(s, 1)){nr} characters -1 is returned.
If there are exactly {nr} characters the length of the string
in bytes is returned.
See charidx() and utf16idx() for getting the character and
UTF-16 index respectively from the byte index.
Examples:echo byteidx('a😊😊', 2) " returns 5
echo byteidx('a😊😊', 2, 1) " returns 1
echo byteidx('a😊😊', 3, 1) " returns 5{expr} (any)

number){id} [, {stream}]) chanclose(){stream} can be one of "stdin", "stdout",
"stderr" or "rpc" (closes stdin/stdout for a job started
with "rpc":v:true) If {stream} is omitted, all streams
are closed. If the channel is a pty, this will then close the
pty master, sending SIGHUP to the job process.
For a socket, there is only one stream, and {stream} should be
omitted.{id} (integer)

0|1)integer){id}, {data}) chansend(){id}. For a job, it writes it to the
stdin of the process. For the stdio channel channel-stdio,
it writes to Nvim's stdout. Returns the number of bytes
written if the write succeeded, 0 otherwise.
See channel-bytes for more information.{data} may be a string, string convertible, Blob, or a list.
If {data} is a list, the items will be joined by newlines; any
newlines in an item will be sent as NUL. To send a final
newline, include a final empty string. Example:call chansend(id, ["abc", "123\n456", ""])"rpc":v:true then the channel expects RPC
messages, use rpcnotify() and rpcrequest() instead.{id} (number)

echo char2nr("á"[0]) " returns 195
echo char2nr("\<M-x>") " returns 128{utf8} is ignored, it exists only for backwards-compatibility.

The index of the first character is zero.
If there are no multibyte characters the returned value is
equal to {idx}.{countcc} is omitted or FALSE, then composing characters
are not counted separately, their byte length is added to the
preceding base character.
When {countcc} is TRUE, then composing characters are
counted as separate characters.{utf16} is present and TRUE, {idx} is used as the UTF-16
index in the String {expr} instead of as the byte index.{idx} bytes. If there are exactly {idx} bytes the length
of the string in characters is returned.echo charidx('áb́ć', 3) " returns 1

{expr} [, {winid}]) col(){expr}.
For accepted positions see getpos().
When {expr} is "$", it means the end of the cursor line, so
the result is the number of bytes in the cursor line plus one.
Additionally {expr} can be [lnum, col]: a List with the line
and column number. Most useful when the column is "$", to get
the last column of a specific line. When "lnum" or "col" is
out of range then col() returns zero.{winid} argument the values are obtained for
that window instead of the current window.echo col(".") " column of cursor

echo col("'t") " column of mark t
echo col("'" .. markname) " column of mark markname{expr} is invalid or when
the window with ID {winid} is not found.
For an uppercase mark the column may actually be in another
buffer.
For the cursor position, when 'virtualedit' is active, the
column is one higher if the cursor is after the end of the
line. Also, when using a <Cmd> mapping the cursor isn't
moved, this can be used to obtain the column in Insert mode:imap <F2> <Cmd>echo col(".").."\n"<CR>{expr} (string|any[])

integer){startcol}, {matches}) complete() E785
Set the matches for Insert mode completion.
Can only be used in Insert mode. You need to use a mapping
with CTRL-R = (see i_CTRL-R). It does not work after CTRL-O
or with an expression mapping.
{startcol} is the byte offset in the line where the completed
text start. The text up to the cursor is the original text
that will be replaced by the matches. Use col('.') for an
empty string. "col('.') - 1" will replace one character by a
match.
{matches} must be a List. Each List item is one match.
See complete-items for the kind of items that are possible.
"longest" in 'completeopt' is ignored.
Note that the after calling this function you need to avoid
inserting anything that would cause completion to stop.
The match can be selected with CTRL-N and CTRL-P as usual with
Insert mode completion. The popup menu will appear if
specified, see ins-completion-menu.
Example:inoremap <F5> <C-R>=ListMonths()<CR>

integer){expr}) copy(){expr}. For Numbers and Strings this isn't
different from using {expr} directly.
When {expr} is a List a shallow copy is created. This means
that the original List can be changed without changing the
copy, and vice versa. But the items are identical, thus
changing an item changes the contents of both Lists.
A Dictionary is copied in a similar way as a List.
Also see deepcopy().{expr} (T)

Positions the cursor at the column (byte count) {col} in the
line {lnum}. The first column is one.{list} this is used as a List
with two, three or four item:
[{lnum}, {col}]
[{lnum}, {col}, {off}]
[{lnum}, {col}, {off}, {curswant}]
This is like the return value of getpos() or getcurpos(),
but without the first item.{col} as the character count, use
setcursorcharpos().{lnum} is used like with getline(), except that if {lnum} is
zero, the cursor will stay in the current line.
If {lnum} is greater than the number of lines in the buffer,
the cursor will be positioned at the last line in the buffer.
If {col} is greater than the number of bytes in the line,
the cursor will be positioned at the last character in the
line.
If {col} is zero, the cursor will stay in the current column.
If {curswant} is given it is used to set the preferred column
for vertical movement. Otherwise {col} is used.{off} specifies the offset in
screen columns from the start of the character. E.g., a
position within a <Tab> or after the last character.
Returns 0 when the position could be set, -1 otherwise.{list} (integer[])

any){expr} [, {noref}]) deepcopy() E698
Make a copy of {expr}. For Numbers and Strings this isn't
different from using {expr} directly.
When {expr} is a List a full copy is created. This means
that the original List can be changed without changing the
copy, and vice versa. When an item is a List, a copy for it
is made, recursively. Thus changing an item in the copy does
not change the contents of the original List.{noref} is omitted or zero a contained List or
Dictionary is only copied once. All references point to
this single copy. With {noref} set to 1 every occurrence of a
List or Dictionary results in a new copy. This also means
that a cyclic reference causes deepcopy() to fail.
E724 {noref} set to 1 will fail.
Also see copy().{expr} (T)

Returns empty string otherwise.
If {expr} starts with "./" the current-directory is used.{expr} (string)
string){expr} argument is a string, which contains one of these:
varname internal variable (see
dict.key internal-variables). Also works
list[i] for curly-braces-names, Dictionary

Beware that evaluating an index may
cause an error message for an invalid
expression. E.g.:let l = [1, 2, 3]
echo exists("l[5]")echo exists("l[xx]")*funcname built-in function (see functions)
or user defined function (see

Otherwise the result is a String and when there are several

any){expr1}, {expr2} [, {expr3}]) extend(){expr1} and {expr2} must be both Lists or both
Dictionaries.{expr2} to {expr1}.
If {expr3} is given insert the items of {expr2} before the
item with index {expr3} in {expr1}. When {expr3} is zero
insert before the first item. When {expr3} is equal to
len({expr1}) then {expr2} is appended.
Examples:echo sort(extend(mylist, [7, 5]))
call extend(mylist, [2, 3], 1){expr1} is the same List as {expr2} then the number of
items copied is equal to the original length of the List.
E.g., when {expr3} is 1 you get N new copies of the first item
(where N is the original length of the List).
Use add() to concatenate one item to a list. To concatenate
two lists into a new list use the + operator:let newlist = [1, 2, 3] + [4, 5]{expr2} to {expr1}.
If a key exists in both {expr1} and {expr2} then {expr3} is
used to decide what to do:
{expr3} = "keep": keep the value of {expr1}
{expr3} = "force": use the value of {expr2}
{expr3} = "error": give an error message E737 {expr3} is omitted then "force" is assumed.{expr1} is changed when {expr2} is not empty. If necessary
make a copy of {expr1} first.
{expr2} remains unchanged.
When {expr1} is locked and {expr2} is not empty the operation
fails.
Returns {expr1}. Returns 0 on error.{expr1} (table)

any){string} [, {mode}]) feedkeys(){string} are queued for processing as if they
come from a mapping or were typed by the user.{string}.{string}, use double-quotes
and "\..." notation expr-quote. For example,
feedkeys("\<CR>") simulates pressing of the <Enter> key. But
feedkeys('\<CR>') pushes 5 characters.
The <Ignore> keycode may be used to exit the
wait-for-character without doing anything.{mode} is a String, which can contain these character flags:
'm' Remap keys. This is default. If {mode} is absent,
keys are remapped.
'n' Do not remap keys.
't' Handle keys as if typed; otherwise they are handled as
if coming from a mapping. This matters for undo,
opening folds, etc.
'L' Lowlevel input. Other flags are not used.
'i' Insert the string instead of appending (see above).
'x' Execute commands until typeahead is empty. This is
similar to using ":normal!". You can call feedkeys()
several times without 'x' and then one time with 'x'
(possibly with an empty {string}) to execute all the
typeahead. Note that when Vim ends in Insert mode it
will behave as if <Esc> is typed, to avoid getting
stuck, waiting for a character to be typed before the
script continues.
Note that if you manage to call feedkeys() while
executing commands, thus calling it recursively, then
all typeahead will be consumed by the last call.
'!' When used with 'x' will not end Insert mode. Can be
used in a test when a timer is set to exit Insert mode
a little later. Useful for testing CursorHoldI.{string} (string)

any){from}, {to}) filecopy(){from} to {to}. The

0|1){file}) filereadable(){file} exists, and can be read. If {file} doesn't exist,
or is a directory, the result is FALSE. {file} is any

If you don't care about the file being readable you can use
glob().
{file} is used as-is, you may want to expand wildcards first:echo filereadable('~/.vimrc')0
echo filereadable(expand('~/.vimrc'))1
{file} (string)
0|1){file}) filewritable(){file} exists, and can be written. If {file} doesn't
exist, or is not writable, the result is 0. If {file} is a
directory, and we can write to it, the result is 2.{file} (string)
0|1){expr1}, {expr2}) filter(){expr1} must be a List, String, Blob or Dictionary.
For each item in {expr1} evaluate {expr2} and when the result
is zero or false remove the item from the List or
Dictionary. Similarly for each byte in a Blob and each
character in a String.{expr2} is a string, inside {expr2} v:val has the value
of the current item. For a Dictionary v:key has the key
of the current item and for a List v:key has the index of
the current item. For a Blob v:key has the index of the
current byte. For a String v:key has the index of the
current character.
Examples:call filter(mylist, 'v:val !~ "OLD"')call filter(mydict, 'v:key >= 8')call filter(var, 0){expr2} is the result of expression and is then
used as an expression again. Often it is good to use a
literal-string to avoid having to double backslashes.{expr2} is a Funcref it must take two arguments:
1. the key or the index of the current item.
2. the value of the current item.
The function must return TRUE if the item should be kept.
Example that keeps the odd items of a list:func Odd(idx, val)
return a:idx % 2 == 1
endfunc
call filter(mylist, function('Odd'))call filter(myList, {idx, val -> idx * val <= 42})call filter(myList, {idx -> idx % 2 == 1})let l = filter(copy(mylist), 'v:val =~ "KEEP"'){expr1}, the List or Dictionary that was filtered,
or a new Blob or String.
When an error is encountered while evaluating {expr2} no
further items in {expr1} are processed.
When {expr2} is a Funcref errors inside a function are ignored,
unless it was defined with the "abort" flag.{expr1} (string|table)

any){list} [, {maxdepth}]) flatten(){list} up to {maxdepth} levels. Without {maxdepth}
the result is a List without nesting, as if {maxdepth} is
a very large number.
The {list} is changed in place, use flattennew() if you do
not want that.
E900 {maxdepth} means how deep in nested lists changes are made.
{list} is not modified when {maxdepth} is 0.
{maxdepth} must be positive number.echo flatten([1, [2, [3, 4]], 5])echo flatten([1, [2, [3, 4]], 5], 1){list} (any[])

any[]|0){expr}) float2nr(){expr} to a Number by omitting the part after the
decimal point.
{expr} must evaluate to a Float or a Number.
Returns 0 if {expr} is not a Float or a Number.
When the value of {expr} is out of range for a Number the
result is truncated to 0x7fffffff or -0x7fffffff (or when
64-bit Number support is enabled, 0x7fffffffffffffff or
-0x7fffffffffffffff). NaN results in -0x80000000 (or when
64-bit Number support is enabled, -0x8000000000000000).
Examples:echo float2nr(3.95)echo float2nr(-23.45)echo float2nr(1.0e100)echo float2nr(-1.0e150)echo float2nr(1.0e-100){expr} (number)

any){expr1}, {expr2}) fmod(){expr1} / {expr2}, even if the
division is not representable. Returns {expr1} - i * {expr2}
for some integer i such that if {expr2} is non-zero, the
result has the same sign as {expr1} and magnitude less than
the magnitude of {expr2}. If {expr2} is zero, the value
returned is zero. The value returned is a Float.
{expr1} and {expr2} must evaluate to a Float or a Number.
Returns 0.0 if {expr1} or {expr2} is not a Float or a
Number.
Examples:echo fmod(12.33, 1.22)echo fmod(-12.33, 1.22){expr1} (number)
{expr2} (number)
any){string}) fnameescape(){string} for use as file name command argument. All
characters that have a special meaning, such as '%' and '|'
are escaped with a backslash.
For most systems the characters escaped are
" \t\n*?[{`$\\%#'\"|!<".} For systems where a backslash
appears in a filename, it depends on the value of 'isfname'.
A leading '+' and '>' is also escaped (special after :edit
and :write). And a "-" by itself (special after :cd).
Returns an empty string on error.
Example:let fname = '+some str%nge|name'
exe "edit " .. fnameescape(fname)edit \+some\ str\%nge\|name{string} (string)
string){fname}, {mods}) fnamemodify(){fname} according to {mods}. {mods} is a
string of characters like it is used for file names on the
command line. See filename-modifiers.
Example:echo fnamemodify("main.c", ":p:h")/home/user/vim/vim/src
{mods} is empty or an unsupported modifier is used then
{fname} is returned.
When {fname} is empty then with {mods} ":h" returns ".", so
that :cd can be used with it. This is different from
expand('%:h') without a buffer name, which returns an empty
string.
Note: Environment variables don't work in {fname}, use
expand() first then.{fname} (string)

string){lnum}) foldclosed(){lnum} is in a closed
fold, the result is the number of the first line in that fold.
If the line {lnum} is not in a closed fold, -1 is returned.

line, "'m" mark m, etc.{lnum} (integer)
integer){lnum}) foldclosedend(){lnum} is in a closed
fold, the result is the number of the last line in that fold.

returned. If there is no fold at line {lnum}, zero is
returned. It doesn't matter if the folds are open or closed.
When used while updating folds (from 'foldexpr') -1 is
returned for lines where folds are still to be updated and the
foldlevel is unknown. As a special case the level of the
previous line is usually available.
{lnum} is used like with getline(). Thus "." is the current
line, "'m" mark m, etc.{lnum} (integer)

line, "'m" mark m, etc.
Useful when exporting folded text, e.g., to HTML.{lnum} (integer)
string){expr1}, {expr2}) foreach(){expr1} must be a List, String, Blob or Dictionary.
For each item in {expr1} execute {expr2}. {expr1} is not
modified; its values may be, as with :lockvar 1. E741
See map() and filter() to modify {expr1}.{expr2} is a string, inside {expr2} v:val has the value
of the current item. For a Dictionary v:key has the key
of the current item and for a List v:key has the index of
the current item. For a Blob v:key has the index of the
current byte. For a String v:key has the index of the
current character.
Examples:call foreach(mylist, 'let used[v:val] = v:true'){expr1} list.{expr2} is the result of expression and is then used
as a command. Often it is good to use a literal-string to
avoid having to double backslashes.{expr2} is a Funcref it must take two arguments:
1. the key or the index of the current item.
2. the value of the current item.
With a lambda you don't get an error if it only accepts one
argument.
If the function returns a value, it is ignored.{expr1} in all cases.
When an error is encountered while executing {expr2} no
further items in {expr1} are processed.

It only works for an autoloaded function if it has already

Return a Funcref variable that refers to function {name}.
{name} can be the name of a user defined function or an
internal function.{name} can also be a Funcref or a partial. When it is a
partial the dict stored in it will be used and the {dict}
argument is not allowed. E.g.:let FuncWithArg = function(dict.Func, [arg])
let Broken = function(dict.Func, [arg], dict){name},
also when it was redefined later. Use funcref() to keep the
same function.{arglist} or {dict} is present this creates a partial.
That means the argument list and/or the dictionary is stored in
the Funcref and will be used when the Funcref is called.func Callback(arg1, arg2, name)

Get information about buffers as a List of Dictionaries.{dict}:
buflisted include only listed buffers.
bufloaded include only loaded buffers.
bufmodified include only modified buffers.{buf} specifies a particular buffer to return
information for. For the use of {buf}, see bufname()

buffer. Otherwise a number must be used.{lnum} is smaller than 1 or bigger than the number of
lines in the buffer, an empty List is returned.{end} is greater than the number of lines in the buffer,
it is treated as {end} is set to the number of lines in the

string){buf}, {varname} [, {def}]) getbufvar(){varname} in buffer {buf}. Note that the name without "b:"
must be used.
The {varname} argument is a string.
When {varname} is empty returns a Dictionary with all the
buffer-local variables.
When {varname} is equal to "&" returns a Dictionary with all
the buffer-local options.
Otherwise, when {varname} starts with "&" returns the value of
a buffer-local option.
This also works for a global or buffer-local option, but it
doesn't work for a global variable, window-local variable or
window-local option.
For the use of {buf}, see bufname() above.
When the buffer or variable doesn't exist {def} or an empty
string is returned, there is no error message.
Examples: let bufmodified = getbufvar(1, "&mod")
echo "todo myvar = " .. getbufvar("todo", "myvar")
Parameters: ~
• {buf} (`integer|string`)
• {varname} (`string`)
• {def} (`any?`)
Return: ~

of {buf}, see bufname() above. If buffer {buf} doesn't
exist, an empty list is returned.{buf} is the current buffer, then the current
position refers to the position in the list. For other
buffers, it is set to the length of the list.{buf} (integer|string?)
table[]){expr}]) getchar(){expr} is omitted, wait until a character is available.
If {expr} is 0, only get a character when one is available.
Return zero otherwise.
If {expr} is 1, only check if a character is available, it is
not consumed. Return zero if no character available.
If you prefer always getting a string use getcharstr().{expr} and when {expr} is 0 a whole character or
special key is returned. If it is a single character, the
result is a Number. Use nr2char() to convert it to a String.
Otherwise a String is returned with the encoded character.
For a special key it's a String with a sequence of bytes
starting with 0x80 (decimal: 128). This is the same value as
the String "\<Key>", e.g., "\<Left>". The returned value is
also a String when a modifier (shift, control, alt) was used
that is not included in the character.{expr} is 0 and Esc is typed, there will be a short delay
while Vim waits to see if this is the start of an escape
sequence.{expr} is 1 only the first byte is returned. For a
one-byte character it is the character itself as a number.
Use nr2char() to convert it to a String.let c = getchar()
if c == "\<LeftMouse>" && v:mouse_win > 0
exe v:mouse_win .. "wincmd w"
exe v:mouse_lnum
exe "normal " .. v:mouse_col .. "|"
endif<Del>
key you get the code for the <Del> key, not the raw character
sequence. Examples:getchar() == "\<Del>"
getchar() == "\<S-Left>"nmap f :call FindChar()<CR>

column number in the returned List is a character index
instead of a byte index.
If getpos() returns a very large column number, equal to

of the last character.getcharpos('.') returns [0, 5, 3, 0]
getpos('.') returns [0, 5, 7, 0]{expr} (string)

string[]){winid}]) getcurpos(){winid} argument can specify the window. It can
be the window number or the window-ID. The last known
cursor position is returned, this may be invalid for the
current value of the buffer if it is not the current window.
If {winid} is invalid a list with zeroes is returned.let save_cursor = getcurpos()
MoveTheCursorAround
call setpos('.', save_cursor){winid} (integer?)

any){winnr} [, {tabnr}]]) getcwd(){winnr} or {tabnr} the working
directory of that scope is returned, and 'autochdir' is
ignored.
Tabs and windows are identified by their respective numbers,
0 means current tab or window. Missing tab number implies 0.
Thus the following are equivalent:getcwd(0)
getcwd(0, 0){winnr} is -1 it is ignored, only the tab is resolved.
{winnr} can be the window number or the window-ID.
If both {winnr} and {tabnr} are -1 the global working
directory is returned.
Throw error if the arguments are invalid. E5000 E5001 E5002{winnr} (integer?)

string){name}) getenv(){name}. The {name}
argument is a string, without a leading '$'. Example:myHome = getenv('HOME'){name} (string)
string){name}]) getfontname(){name} is a
valid font name. If not then an empty string is returned.
Otherwise the actual font name is returned, or {name} if the
GUI does not support obtaining the real name.
Only works when the GUI is running, thus not in your vimrc or
gvimrc file. Use the GUIEnter autocommand to use this
function just after the GUI has started.{name} (string?)
string){fname}) getfperm(){fname}.
If {fname} does not exist or its directory cannot be read, an
empty string is returned.
The result is of the form "rwxrwxrwx", where each group of
"rwx" flags represent, in turn, the permissions of the owner
of the file, the group the file belongs to, and other users.
If a user does not have a given permission the flag for this
is replaced with the string "-". Examples:echo getfperm("/etc/passwd")
echo getfperm(expand("~/.config/nvim/init.vim")){fname} (string)
string){fname}) getfsize(){fname}.
If {fname} is a directory, 0 is returned.
If the file {fname} can't be found, -1 is returned.
If the size of {fname} is too big to fit in a Number then -2
is returned.{fname} (string)
integer){fname}) getftime(){fname}. The value is measured as seconds
since 1st Jan 1970, and may be passed to strftime(). See also
localtime() and strftime().
If the file {fname} can't be found -1 is returned.{fname} (string)
integer){fname}) getftype(){fname}.
If {fname} does not exist an empty string is returned.
Here is a table over different kinds of files and their
results:
Normal file "file"
Directory "dir"
Symbolic link "link"
Block device "bdev"
Character device "cdev"
Socket "socket"
FIFO "fifo"
All other "other"
Example:getftype("/home"){fname} (string)
'file'|'dir'|'link'|'bdev'|'cdev'|'socket'|'fifo'|'other'){winnr} only use this window in the current tab page.
{winnr} can also be a window-ID.
With {winnr} and {tabnr} use the window in the specified tab
page. If {winnr} or {tabnr} is invalid, an empty list is
returned.{winnr} (integer?)
{tabnr} (integer?)
vim.fn.getjumplist.ret){lnum} [, {end}]) getline(){end} the result is a String, which is line {lnum}
from the current buffer. Example:getline(1){lnum} is a String that doesn't start with a
digit, line() is called to translate the String into a Number.
To get the line under the cursor:getline("."){lnum} is a number smaller than 1 or bigger than the
number of lines in the buffer, an empty string is returned.{end} is given the result is a List where each item is
a line from the current buffer in the range {lnum} to {end},
including line {end}.
{end} is used in the same way as {lnum}.
Non-existing lines are silently omitted.
When {end} is before {lnum} an empty List is returned.
Example:let start = line('.')
let end = search("^$") - 1
let lines = getline(start, end){lnum} (integer|string)
{end} (nil|false?)
string){nr} [, {what}]) getloclist(){nr}. {nr} can be the window number or the window-ID.
When {nr} is zero the current window is used.{nr}, an empty list is
returned. Otherwise, same as getqflist().{what} dictionary argument is supplied, then
returns the items listed in {what} as a dictionary. Refer to
getqflist() for the supported items in {what}.{what},
the following item is supported by getloclist():{nr}.
Returns an empty Dictionary if window {nr} does not exist.echo getloclist(3, {'all': 0})
echo getloclist(5, {'filewinid': 0}){nr} (integer)
{what} (table?)
any){buf}]) getmarklist(){buf} argument returns a List with information
about all the global marks. mark{buf} argument is specified, returns the
local marks defined in buffer {buf}. For the use of {buf},
see bufname(). If {buf} is invalid, an empty list is
returned.{buf} (integer??)
vim.fn.getmarklist.ret.item[]){win}]) getmatches(){win} is specified, use the window with this number or
window ID instead of the current window. If {win} is invalid,
an empty list is returned.
Example:echo getmatches()[{"group": "MyGroup1", "pattern": "TODO",
"priority": 10, "id": 1}, {"group": "MyGroup2",
"pattern": "FIXME", "priority": 10, "id": 2}]let m = getmatches()

any)vim.fn.getmousepos.ret)integer){expr}) getpos(){expr}.
The accepted values for {expr} are:
. The cursor position.
$ The last line in the current buffer.
'x Position of mark x (if the mark is not set, 0 is
returned for all values).
w0 First line visible in current window (one if the
display isn't updated, e.g. in silent Ex mode).
w$ Last line visible in current window (this is one
less than "w0" if no lines are visible).
v When not in Visual mode, returns the cursor
position. In Visual mode, returns the other end
of the Visual area. A good way to think about
this is that in Visual mode "v" and "." complement
each other. While "." refers to the cursor
position, "v" refers to where v_o would move the
cursor. As a result, you can use "v" and "."
together to work on all of a selection in
characterwise Visual mode. If the cursor is at
the end of a characterwise Visual area, "v" refers
to the start of the same Visual area. And if the
cursor is at the start of a characterwise Visual
area, "v" refers to the end of the same Visual
area. "v" differs from '< and '> in that it's
updated right away.
Note that a mark in another file can be used. The line number
then applies to another buffer.<Tab> or after the last
character.{expr} is invalid, returns a list with all zeros.let save_a_mark = getpos("'a")

If "nr" is not present then the current quickfix list is used.
If both "nr" and a non-zero "id" are specified, then the list
specified by "id" is used.
To get the number of lists in the quickfix stack, set "nr" to
"$" in {what}. The "nr" value in the returned dictionary
contains the quickfix stack size.

to specify positions from a different buffer, but please
note the limitations at getregion-notes.{opts} is a Dict and supports the
following items:{pos1} and {pos2} doesn't matter, it will always
return content from the upper left position to the lower

When {varname} is equal to "&" get the values of all
window-local options in a Dictionary.
Otherwise, when {varname} starts with "&" get the value of a

Note that {varname} must be the name without "w:".
Tabs are numbered starting with one. For the current tabpage
use getwinvar().
{winnr} can be the window number or the window-ID.
When {winnr} is zero the current window is used.
This also works for a global option, buffer-local option and

This is mainly for use in the distributed Vim scripts. When
generating message translations the {text} is extracted by

called.
For {text} double quoted strings are preferred, because
xgettext does not understand escaping in single quoted

Make sure {textlist} has less than 'lines' entries, otherwise
it won't work. It's a good idea to put the entry number at
the start of the string. And put a prompt in the first item.

Call function {funcname} in the run-time library {libname}
with single argument {argument}.
This is useful to call functions in a library that you
especially made to be used with Vim. Since only one argument
is possible, calling standard library functions is rather
limited.
The result is the String returned by the function. If the
function returns NULL, this will appear as an empty string ""
to Vim.
If the function returns a number, use libcallnr()!
If {argument} is a number, it is passed to the function as an
int; if {argument} is a string, it is passed as a
null-terminated string.{libname} should be the filename of the DLL
without the ".DLL" suffix. A full path is only required if
the DLL is not in the usual places.

Returns 0.0 if {expr} is not a Float or a Number.
Examples:echo log(10)echo log(exp(5)){expr} (number)
number){expr}) log10(){expr} to base 10 as a Float.
{expr} must evaluate to a Float or a Number.
Returns 0.0 if {expr} is not a Float or a Number.

to Vim data structures. See lua-eval for more details.{expr} (string)
{expr1} (any[]?)
any){expr1}, {expr2}) map(){expr1} must be a List, String, Blob or Dictionary.
When {expr1} is a List or Dictionary, replace each
item in {expr1} with the result of evaluating {expr2}.
For a Blob each byte is replaced.
For a String, each character, including composing
characters, is replaced.
If the item type changes you may want to use mapnew() to
create a new List or Dictionary.{expr2} is a String, inside {expr2} v:val has the value
of the current item. For a Dictionary v:key has the key
of the current item and for a List v:key has the index of
the current item. For a Blob v:key has the index of the
current byte. For a String v:key has the index of the
current character.
Example:call map(mylist, '"> " .. v:val .. " <"'){expr2} is the result of an expression and is then
used as an expression again. Often it is good to use a
literal-string to avoid having to double backslashes. You
still have to double ' quotes{expr2} is a Funcref it is called with two arguments:
1. The key or the index of the current item.
2. the value of the current item.
The function must return the new value of the item. Example
that changes each value by "key-value":func KeyValue(key, val)
return a:key .. '-' .. a:val
endfunc
call map(myDict, function('KeyValue'))call map(myDict, {key, val -> key .. '-' .. val})call map(myDict, {key -> 'item: ' .. key})call map(myDict, {_, val -> 'item: ' .. val})let tlist = map(copy(mylist), ' v:val .. "\t"'){expr1}, the List or Dictionary that was filtered,
or a new Blob or String.
When an error is encountered while evaluating {expr2} no
further items in {expr1} are processed.
When {expr2} is a Funcref errors inside a function are ignored,
unless it was defined with the "abort" flag.{expr1} (string|table|any[])

any){name} [, {mode} [, {abbr} [, {dict}]]]) maparg(){dict} is omitted or zero: Return the rhs of mapping
{name} in mode {mode}. The returned String has special
characters translated like in the output of the ":map" command
listing. When {dict} is TRUE a dictionary is returned, see
below. To get a list of all mappings see maplist().{name}, an empty String is
returned if {dict} is FALSE, otherwise returns an empty Dict.
When the mapping for {name} is empty, then "<Nop>" is
returned.{name} can have special key names, like in the ":map"
command.{mode} can be one of these strings:
"n" Normal
"v" Visual (including Select)
"o" Operator-pending
"i" Insert
"c" Cmd-line
"s" Select
"x" Visual
"l" langmap language-mapping
"t" Terminal
"" Normal, Visual and Operator-pending
When {mode} is omitted, the modes for "" are used.{abbr} is there and it is TRUE use abbreviations
instead of mappings.{dict} is there and it is TRUE return a dictionary
containing all the information of the mapping with the
following items: mapping-dict {lhs} of the mapping as it would be typed
"lhsraw" The {lhs} of the mapping as raw bytes
"lhsrawalt" The {lhs} of the mapping as raw bytes, alternate
form, only present when it differs from "lhsraw"
"rhs" The {rhs} of the mapping as typed.
"callback" Lua function, if RHS was defined as such.
"silent" 1 for a :map-silent mapping, else 0.
"noremap" 1 if the {rhs} of the mapping is not remappable.
"script" 1 if mapping was defined with <script>.
"expr" 1 for an expression mapping (:map-<expr>).
"buffer" 1 for a buffer local mapping (:map-local).
"mode" Modes for which the mapping is defined. In
addition to the modes mentioned above, these
characters will be used:
" " Normal, Visual and Operator-pending
"!" Insert and Commandline mode
(mapmode-ic)
"sid" The script local ID, used for <sid> mappings
(<SID>). Negative for special contexts.
"scriptversion" The version of the script, always 1.
"lnum" The line number in "sid", zero if unknown.
"nowait" Do not wait for other, longer mappings.
(:map-<nowait>).
"abbr" True if this is an abbreviation.
"mode_bits" Nvim's internal binary representation of "mode".
mapset() ignores this; only "mode" is used.

are from src/nvim/state_defs.h and may change in
the future.exe 'nnoremap <Tab> ==' .. maparg('<Tab>', 'n'){name} (string)

{mode}. See maparg() for {mode} and special names in
{name}.
When {abbr} is there and it is non-zero use abbreviations
instead of mappings.
A match happens with a mapping that starts with {name} and
with a mapping which is equal to the start of {name}.{name}, while maparg() only finds a
mapping for {name} exactly.
When there is no mapping that starts with {name}, an empty
String is returned. If there is one, the RHS of that mapping
is returned. If there are several mappings that start with
{name}, the RHS of one of them is returned. This will be
"<Nop>" if the RHS is empty.
The mappings local to the current buffer are checked first,
then the global mappings.
This function can be used to check if a mapping can be added
without being ambiguous. Example:if mapcheck("_vv") == ""
map _vv :set guifont=7x13<CR>

any){mode}, {abbr}, {dict}) mapset(){dict})
Restore a mapping from a dictionary, possibly returned by
maparg() or maplist(). A buffer mapping, when dict.buffer
is true, is set on the current buffer; it is up to the caller
to ensure that the intended buffer is the current buffer. This
feature allows copying mappings from one buffer to another.
The dict.mode value may restore a single mapping that covers
more than one mode, like with mode values of '!', ' ', "nox",
or 'v'. E1276{mode} and {abbr} should be the same as
for the call to maparg(). E460
{mode} is used to define the mode in which the mapping is set,
not the "mode" entry in {dict}.
Example for saving and restoring a mapping:let save_map = maparg('K', 'n', 0, 1)
nnoremap K somethingelse
" ...
call mapset('n', 0, save_map):map!, you need to save/restore the mapping for
all of them, when they might differ.{dict} as the only argument, mode
and abbr are taken from the dict.
Example:let save_maps = maplist()->filter(
\ {_, m -> m.lhs == 'K'})
nnoremap K somethingelse
cnoremap K somethingelse2
" ...
unmap K
for d in save_maps
call mapset(d)

any){expr}, {pat} [, {start} [, {count}]]) match(){expr} is a List then this returns the index of the
first item where {pat} matches. Each item is used as a
String, Lists and Dictionaries are used as echoed.{expr} is used as a String. The result is a
Number, which gives the index (byte offset) in {expr} where
{pat} matches.echo match("testing", "ing") " results in 4
echo match([1, 'x'], '\a') " results in 1{pat} is used.
strpbrk() let sepidx = match(line, '[.,;: \t]')let idx = match(haystack, '\cneedle'){start} is given, the search starts from byte index
{start} in a String or item {start} in a List.
The result, however, is still the index counted from the
first character/item. Example:echo match("testing", "ing", 2)echo match("testing", "ing", 4)echo match("testing", "t", 2){start} > 0 then it is like the string starts
{start} bytes later, thus "^" will match at {start}. Except
when {count} is given, then it's like matches before the
{start} byte are ignored (this is a bit complicated to keep it
backwards compatible).
For a String, if {start} < 0, it will be set to 0. For a list
the index is counted from the end.
If {start} is out of range ({start} > strlen({expr}) for a
String or {start} > len({expr}) for a List) -1 is returned.{count} is given use the {count}th match. When a match
is found in a String the search for the next one starts one
character further. Thus this example results in 1:echo match("testing", "..", 0, 2){count} is added the way {start} works changes,
see above.{expr} (string|any[])

any){group}, {pattern} [, {priority} [, {id} [, {dict}]]])
Defines a pattern to be highlighted in the current window (a
"match"). It will be highlighted with {group}. Returns an
identification number (ID), which can be used to delete the
match using matchdelete(). The ID is bound to the window.
Matching is case sensitive and magic, unless case sensitivity
or magicness are explicitly overridden in {pattern}. The
'magic', 'smartcase' and 'ignorecase' options are not used.
The "Conceal" value is special, it causes the match to be
concealed.{priority} argument assigns a priority to the
match. A match with a high priority will have its
highlighting overrule that of a match with a lower priority.
A priority is specified as an integer (negative numbers are no
exception). If the {priority} argument is not specified, the
default priority is 10. The priority of 'hlsearch' is zero,
hence all matches with a priority greater than zero will
overrule it. Syntax highlighting (see 'syntax') is a separate
mechanism, and regardless of the chosen priority a match will
always overrule syntax highlighting.{id} argument allows the request for a specific
match ID. If a specified ID is already taken, an error
message will appear and the match will not be added. An ID
is specified as a positive integer (zero excluded). IDs 1, 2
and 3 are reserved for :match, :2match and :3match,
respectively. 3 is reserved for use by the matchparen
plugin.
If the {id} argument is not specified or -1, matchadd()
automatically chooses a free ID, which is at least 1000.{dict} argument allows for further custom
values. Currently this is used to specify a match specific
conceal character that will be shown for hl-Conceal
highlighted matches. The dict can have the following members:highlight MyGroup ctermbg=green guibg=green
let m = matchadd("MyGroup", "TODO")call matchdelete(m){group} (integer|string)
{pattern} (string)
{priority} (integer?)
{id} (integer?)
{dict} (string?)
any){group}, {pos} [, {priority} [, {id} [, {dict}]]]) matchaddpos()
Same as matchadd(), but requires a list of positions {pos}
instead of a pattern. This command is faster than matchadd()
because it does not handle regular expressions and it sets
buffer line boundaries to redraw screen. It is supposed to be
used when fast match additions and deletions are required, for
example to highlight matching parentheses.
E5030 E5031
{pos} is a list of positions. Each position can be one of
these:
highlight MyGroup ctermbg=green guibg=green
let m = matchaddpos("MyGroup", [[23, 24], 34])call matchdelete(m){group} (integer|string)
{pos} (any[])
{priority} (integer?)
{id} (integer?)
{dict} (string?)
any){nr}) matcharg(){nr} match item, as set with a :match,
:2match or :3match command.
Return a List with two elements:
The name of the highlight group used
The pattern used.
When {nr} is not 1, 2 or 3 returns an empty List.
When there is no match item set returns ['', ''].
This is useful to save and restore a :match.
Highlighting matches using the :match commands are limited
to three matches. matchadd() does not have this limitation.{nr} (integer)
any){buf}, {pat}, {lnum}, {end}, [, {dict}]) matchbufline(){lnum} to {end} in
buffer {buf} where {pat} matches.{lnum} and {end} can either be a line number or the string "$"
to refer to the last line in {buf}.{dict} argument supports following items:
submatches include submatch information (/\(){buf} is not a valid buffer, the buffer is not loaded or
{lnum} or {end} is not valid then an error is given and an
empty List is returned." Assuming line 3 in buffer 5 contains "a"
echo matchbufline(5, '\<\k\+\>', 3, 3)[{'lnum': 3, 'byteidx': 0, 'text': 'a'}]" Assuming line 4 in buffer 10 contains "tik tok"

Call nvim api functions. The type checking of arguments will
be stricter than for most other builtins. For instance,
if Integer is expected, a Number must be passed in, a
String will not be autoconverted.
Buffer numbers, as returned by bufnr() could be used as
first argument to nvim_buf_... functions. All functions
expecting an object (buffer, window or tabpage) can
also take the numerical value 0 to indicate the current

result. The tail, the file name, is kept as-is. The other
components in the path are reduced to {len} letters in length.
If {len} is omitted or smaller than 1 then 1 is used (single
letters). Leading '~' and '.' characters are kept. Examples:echo pathshorten('~/.config/nvim/autoload/file1.vim')echo pathshorten('~/.config/nvim/autoload/file2.vim', 2){path} (string)

also on 64 bits systems, for consistency.
{expr} can be initialized by srand() and will be updated by
rand(). If {expr} is omitted, an internal seed value is used
and updated.
Returns -1 if {expr} is invalid.echo rand()

any){expr} [, {max} [, {stride}]]) range() E726 E727
Returns a List with Numbers:
{expr} is specified: [0, 1, ..., {expr} - 1]
{max} is specified: [{expr}, {expr} + 1, ..., {max}]
{stride} is specified: [{expr}, {expr} + {stride}, ...,
{max}] (increasing {expr} with {stride} each time, not
producing a value past {max}).
When the maximum is one before the start the result is an
empty list. When the maximum is more than one before the
start this is an error.
Examples:echo range(4) " [0, 1, 2, 3]
echo range(2, 4) " [2, 3, 4]
echo range(2, 9, 3) " [2, 5, 8]

any){fname} [, {offset} [, {size}]]) readblob(){fname} in binary mode and return a Blob.
If {offset} is specified, read the file from the specified
offset. If it is a negative value, it is used as an offset
from the end of the file. E.g., to read the last 12 bytes:echo readblob('file.bin', -12){size} is specified, only the specified size will be read.
E.g. to read the first 100 bytes of a file:echo readblob('file.bin', 0, 100){size} is -1 or omitted, the whole data starting from
{offset} will be read.
This can be also used to read the data from a character device
on Unix when {size} is explicitly set. Only if the device
supports seeking {offset} can be used. Otherwise it should be
zero. E.g. to read 10 bytes from a serial console:echo readblob('/dev/ttyS0', 0, 10){fname} (string)

{size} (integer?)
any){directory} [, {expr}]) readdir(){directory}.
You can also use glob() if you don't need to do complicated
things, such as limiting the number of matches.{expr} is omitted all entries are included.
When {expr} is given, it is evaluated to check what to do:
If {expr} results in -1 then no further entries will
be handled.
If {expr} results in 0 then this entry will not be
added to the list.
If {expr} results in 1 then this entry will be added
to the list.
Each time {expr} is evaluated v:val is set to the entry name.
When {expr} is a function the name is passed as the argument.
For example, to get a list of files ending in ".txt":echo readdir(dirname, {n -> n =~ '.txt$'})echo readdir(dirname, {n -> n !~ '^\.\|\~$'})function! s:tree(dir)
return {a:dir : map(readdir(a:dir),

endfunction
echo s:tree("."){directory} (string)
{expr} (integer?)
any){fname} [, {type} [, {max}]]) readfile(){fname} and return a List, each line of the file
as an item. Lines are broken at NL characters. Macintosh
files separated with CR will result in a single long line
(unless a NL appears somewhere).
All NUL characters are replaced with a NL character.
When {type} contains "b" binary mode is used:
{max} is given this specifies the maximum number of lines
to be read. Useful if you only want to check the first ten
lines of a file:for line in readfile(fname, '', 10)
if line =~ 'Date' | echo line | endif
endfor{max} is negative -{max} lines from the end of the file
are returned, or as many as there are.
When {max} is zero the result is an empty list.
Note that without {max} the whole file is read into memory.
Also note that there is no recognition of encoding. Read a
file into a buffer if you need to.
Deprecated (use readblob() instead): When {type} contains
"B" a Blob is returned with the binary data of the file
unmodified.
When the file can't be opened an error message is given and
the result is an empty list.

any){object}, {func} [, {initial}]) reduce() E998
{func} is called for every item in {object}, which can be a
String, List or a Blob. {func} is called with two
arguments: the result so far and current item. After
processing all items the result is returned.{initial} is the initial result. When omitted, the first item
in {object} is used and {func} is first called for the second
item. If {initial} is not given and {object} is empty no
result can be computed, an E998 error is given.echo reduce([1, 3, 5], { acc, val -> acc + val })

reltime({start}, {end})
Return an item that represents a time value. The item is a
list with items that depend on the system.
The item can be passed to reltimestr() to convert it to a
string or reltimefloat() to convert to a Float.{start}
and {end}.{start} and {end} arguments must be values returned by
reltime(). Returns zero on error.{start} (any?)
{end} (any?)
any){time}) reltimefloat(){time}.
Unit of time is seconds.
Example:
let start = reltime()
call MyFunction()
let seconds = reltimefloat(reltime(start))
See the note of reltimestr() about overhead.
Also see profiling.
If there is an error an empty string is returned{time} (any)
any){time}) reltimestr(){time}.
This is the number of seconds, a dot and the number of
microseconds. Example:let start = reltime()
call MyFunction()
echo reltimestr(reltime(start))echo split(reltimestr(reltime(start)))[0]{time} (any)
any){list}, {idx}) remove(){list}, {idx}, {end})
Without {end}: Remove the item at {idx} from List {list} and
return the item.
With {end}: Remove items from {idx} to {end} (inclusive) and
return a List with these items. When {idx} points to the same
item as {end} a list with one item is returned. When {end}
points to an item before {idx} this is an error.
See list-index for possible values of {idx} and {end}.
Returns zero on error.
Example:echo "last item: " .. remove(mylist, -1)
call remove(mylist, 0, 9){list} (any[])
{idx} (integer)
{end} (integer?)
any){blob}, {idx})
remove({blob}, {idx}, {end})
Without {end}: Remove the byte at {idx} from Blob {blob} and
return the byte.
With {end}: Remove bytes from {idx} to {end} (inclusive) and
return a Blob with these bytes. When {idx} points to the same
byte as {end} a Blob with one byte is returned. When {end}
points to a byte before {idx} this is an error.
Returns zero on error.
Example:echo "last byte: " .. remove(myblob, -1)
call remove(mylist, 0, 9){blob} (any)
{idx} (integer)
{end} (integer?)
any){dict}, {key})
Remove the entry from {dict} with key {key} and return it.
Example:echo "removed " .. remove(dict, "one"){key} in {dict} this is an error.
Returns zero on error.{dict} (any)
{key} (string)
any){from}, {to}) rename(){from} to the name {to}. This
should also work to move files across file systems. The
result is a Number, which is 0 if the file was renamed
successfully, and non-zero when the renaming failed.
NOTE: If {to} exists it is overwritten without warning.
This function is not available in the sandbox.{from} (string)
{to} (string)
integer){expr}, {count}) repeat(){expr} {count} times and return the concatenated
result. Example:let separator = repeat('-', 80){count} is zero or negative the result is empty.
When {expr} is a List or a Blob the result is {expr}
concatenated {count} times. Example:let longlist = repeat(['a', 'b'], 3){expr} (any)
{count} (integer)
any){filename}) resolve() E655
On MS-Windows, when {filename} is a shortcut (a .lnk file),
returns the path the shortcut points to in a simplified form.
On Unix, repeat resolving symbolic links in all path
components of {filename} and return the simplified result.
To cope with link cycles, resolving of symbolic links is
stopped after 100 iterations.
On other systems, return the simplified {filename}.
The simplification step is done as by simplify().
resolve() keeps a leading path component specifying the
current directory (provided the result is still a relative
path name) and also keeps a trailing path separator.{filename} (string)
string){object}) reverse(){object}. {object} can be a
List, a Blob or a String. For a List and a Blob the
items are reversed in-place and {object} is returned.
For a String a new String is returned.
Returns zero if {object} is not a List, Blob or a String.
If you want a List or Blob to remain unmodified make a copy
first:let revlist = reverse(copy(mylist)){object} (T[])
T[]){expr}) round(){expr} to the nearest integral value and return it
as a Float. If {expr} lies halfway between two integral
values, then use the larger one (away from zero).
{expr} must evaluate to a Float or a Number.
Returns 0.0 if {expr} is not a Float or a Number.
Examples:echo round(0.456)echo round(4.5)echo round(-4.5){expr} (number)
number){channel}, {event} [, {args}...]) rpcnotify(){event} to {channel} via RPC and returns immediately.

{col}. {col} is a one-based byte index.
The Dict has these members:
row screen row
col first screen column
endcol last screen column
curscol cursor screen column
If the specified position is not visible, all values are zero.
The "endcol" value differs from "col" when the character
occupies more than one screen cell. E.g. for a Tab "col" can
be 1 and "endcol" can be 8.
The "curscol" value is where the cursor would be placed. For
a Tab it would be the same as "endcol", while for a double
width character it would be the same as "col".
The conceal feature is ignored here, the column numbers are
as if 'conceallevel' is zero. You can set the cursor to the
right position and use screencol() to get the value with
conceal taken into account.
If the position is in a closed fold the screen position of the
first character is returned, {col} is not used.

string){pattern} [, {flags} [, {stopline} [, {timeout} [, {skip}]]]]) search()
Search for regexp pattern {pattern}. The search starts at the
cursor position (you can use cursor() to set it).{flags} is a String, which can contain these character flags:
'b' search Backward instead of forward
'c' accept a match at the Cursor position
'e' move to the End of the match
'n' do Not move the cursor
'p' return number of matching sub-Pattern (see below)
's' Set the ' mark at the previous location of the cursor
'w' Wrap around the end of the file
'W' don't Wrap around the end of the file
'z' start searching at the cursor column instead of Zero
If neither 'w' or 'W' is given, the 'wrapscan' option applies.{stopline} argument is given then the search stops
after searching this line. This is useful to restrict the
search to a range of lines. Examples:let match = search('(', 'b', line("w0"))
let end = search('END', '', line("w$")){stopline} is used and it is not zero this also implies
that the search does not wrap around the end of the file.
A zero value is equal to not giving the argument.{timeout} argument is given the search stops when
more than this many milliseconds have passed. Thus when
{timeout} is 500 the search stops after half a second.
The value must not be negative. A zero value is like not
giving the argument.{skip} expression.{skip} expression is given it is evaluated with the
cursor positioned on the start of a match. If it evaluates to
non-zero this match is skipped. This can be used, for
example, to skip a match in a comment or a string.
{skip} can be a string, which is evaluated as an expression, a
function reference or a lambda.
When {skip} is omitted or empty, every match is accepted.
When evaluating {skip} causes an error the search is aborted
and -1 returned.

Search for the match of a nested start-end pair. This can be
used to find the "endif" that matches an "if", while other
if/endif pairs in between are ignored.
The search starts at the cursor. The default is to search
forward, include 'b' in {flags} to search backward.
If a match is found, the cursor is positioned at it and the
line number is returned. If no match is found 0 or -1 is
returned and the cursor doesn't move. No error message is
given.{start}, {middle} and {end} are patterns, see pattern. They
must not contain \( \) pairs. Use of \%( \) is allowed. When
{middle} is not empty, it is found when searching from either

typical use is:echo searchpair('\<if\>', '\<else\>', '\<endif\>'){middle} empty the "else" is skipped.{flags} 'b', 'c', 'n', 's', 'w' and 'W' are used like with
search(). Additionally:
'r' Repeat until no more matches found; will find the
outer pair. Implies the 'W' flag.
'm' Return number of matches instead of line number with
the match; will be > 1 when 'r' is used.
Note: it's nearly always a good idea to use the 'W' flag, to
avoid wrapping around the end of the file.{start}, {middle} or {end} is found, the
{skip} expression is evaluated with the cursor positioned on
the start of the match. It should return non-zero if this

When {skip} is omitted or empty, every match is accepted.
When evaluating {skip} causes an error the search is aborted
and -1 returned.
{skip} can be a string, a lambda, a funcref or a partial.

direction of searching, is the first one found. Example:if 1

"l" or "V" linewise mode
"b" or "<CTRL-V>" blockwise-visual mode
If a number immediately follows "b" or "<CTRL-V>" then this is
used as the width of the selection - if it is not specified
then the width of the block is set to the number of characters
in the longest line (counting a <Tab> as 1 character).
If {options} contains "u" or '"', then the unnamed register is
set to point to register {regname}.{options} contains no register settings, then the default
is to use character mode unless {value} ends in a <NL> for
string {value} and linewise mode for list {value}. Blockwise

language in 'spelllang' for the current window that supports
soundfolding. 'spell' must be set. When no sound folding is
possible the {word} is returned unmodified.
This can be used for making spelling suggestions. Note that
the method can be quite slow.{word} (string)

When {max} is given up to this number of suggestions are
returned. Otherwise up to 25 suggestions are returned.{capital} argument is given and it's non-zero only
suggestions with a leading capital will be given. Use this
after a match with 'spellcapcheck'.{word} can be a badly spelled word followed by other text.
This allows for joining two words that were split. The
suggestions also include the following text, thus you can
replace a line.{word} may also be a good word. Similar words will then be
returned. {word} itself is not included in the suggestions,
although it may appear capitalized.{word} (string)

string[]){string} [, {pattern} [, {keepempty}]]) split(){string}. When {pattern} is omitted or
empty each white space separated sequence of characters
becomes an item.
Otherwise the string is split where {pattern} matches,
removing the matched characters. 'ignorecase' is not used
here, add \c to ignore case. /\c
When the first or last item is empty it is omitted, unless the
{keepempty} argument is given and it's non-zero.
Other empty items are kept when {pattern} matches at least one
character or when {keepempty} is non-zero.
Example:let words = split(getline('.'), '\W\+')for c in split(mystring, '\zs') | endforecho split('abc:def:ghi', ':\zs')['abc:', 'def:', 'ghi']

string[]){expr}) sqrt(){expr} as a
Float.
{expr} must evaluate to a Float or a Number. When {expr}
is negative the result is NaN (Not a Number). Returns 0.0 if
{expr} is not a Float or a Number.
Examples:echo sqrt(100)echo sqrt(-4.01){expr} (number)
any){expr}]) srand(){expr} is not given, seed values are initialized by
reading from /dev/urandom, if possible, or using time(NULL)

string|string[]){string} [, {quoted}]) str2float(){string} to a Float. This mostly works the
same as when using a floating point number in an expression,
see floating-point-format. But it's a bit more permissive.
E.g., "1e40" is accepted, while in an expression you need to
write "1.0e40". The hexadecimal form "0x123" is also
accepted, but not others, like binary or octal.
When {quoted} is present and non-zero then embedded single
quotes before the dot are ignored, thus "1'000.0" is a
thousand.
Text after the number is silently ignored.
The decimal point is always '.', no matter what the locale is
set to. A comma ends the number: "12,345.67" is converted to
12.0. You can strip out thousands separators with
substitute():let f = str2float(substitute(text, ',', '', 'g')){string} (string)

{base} is the conversion base, it can be 2, 8, 10 or 16.
When {quoted} is present and non-zero then embedded single
quotes are ignored, thus "1'000'000" is a million.{base} is omitted base 10 is used. This also means that
a leading zero doesn't cause octal conversion to be used, as
with the default String to Number conversion. Example:let nr = str2nr('0123'){base} is 16 a leading "0x" or "0X" is ignored. With a
different base the result will be zero. Similarly, when
{base} is 8 a leading "0", "0o" or "0O" is ignored, and when
{base} is 2 a leading "0b" or "0B" is ignored.
Text after the number is silently ignored.{string} is empty or on error.{string} (string)

composing characters separately.{string} is empty or on error.{string} (string)
any){src}, {start} [, {len} [, {skipcc}]]) strcharpart(){skipcc} is omitted or zero, composing characters are
counted separately.
When {skipcc} set to 1, composing characters are treated as a
part of the preceding base character, similar to slice().
When a character index is used where a character does not
exist it is omitted and counted as one character. For
example:echo strcharpart('abc', -1, 2){src} (string)
{start} (integer)
{len} (integer?)
{skipcc} (boolean?)
any){string} [, {skipcc}]) strchars(){string}.
When {skipcc} is omitted or zero, composing characters are
counted separately.
When {skipcc} set to 1, composing characters are ignored.
strcharlen() always does this.{skipcc} is only available after 7.4.755. For backward
compatibility, you can define a wrapper function:if has("patch-7.4.755")

(first column is zero). When {col} is omitted zero is used.
Otherwise it is the screen column where to start. This
matters for Tab characters.
The option settings of the current window are used. This
matters for anything that's displayed differently, such as
'tabstop' and 'display'.

integer){format} [, {time}]) strftime(){format} string. The given {time} is used,
or the current time if no time is given. The accepted
{format} depends on your system, thus this is not portable!
See the manual page of the C function strftime() for the
format. The maximum length of the result is 80 characters.
See also localtime(), getftime() and strptime().
The language can be changed with the :language command.
Examples: echo strftime("%c") " Sun Apr 27 11:49:23 1997
echo strftime("%Y %b %d %X") " 1997 Apr 27 11:53:25
echo strftime("%y%m%d %T") " 970427 11:53:55

Note that in String values the ' character is doubled.
Also see strtrans().
Note 2: Output format is mostly compatible with YAML, except
for infinite and NaN floating-point values representations
which use str2float(). Strings are also dumped literally,
only single quote is escaped, which does not allow using YAML
for parsing back binary strings. eval() should always work
for strings and floats though, and this is the only official
method. Use msgpackdump() or json_encode() if you need to

If the argument is a Number it is first converted to a String.
For other types an error is given and zero is returned.

integer){src}, {start} [, {len} [, {chars}]]) strpart(){src}, starting from
byte {start}, with the byte length {len}.
When {chars} is present and TRUE then {len} is the number of
characters positions (composing characters are not counted
separately, thus "1" means one base character and any
following composing characters).
To count {start} as characters instead of bytes use
strcharpart().{len} is missing, the copy continues from {start} till the
end of the {src}.echo strpart("abcdefg", 3, 2) " returns 'de'
echo strpart("abcdefg", -2, 4) " returns 'ab'

for the format. Especially avoid "%c". The value of $TZ also
matters.{timestring} cannot be parsed with {format} zero is
returned. If you do not know the format of {timestring} you
can try different {format} values until you get a non-zero

Only for an expression in a :substitute command or

Note that a NL in the string can stand for a line break of a
multi-line match or a NUL character in the text.
Also see sub-replace-expression.{list} is present and non-zero then submatch() returns
a list of strings, similar to getline() with two arguments.
NL characters in the text represent NUL characters in the

option is set and 'cpoptions' is empty (to make scripts
portable). 'ignorecase' is still relevant, use /\c or /\C
if you want to ignore or match case and ignore 'ignorecase'.
'smartcase' is not used. See string-match for how {pat} is
used.{sub} is not replaced with the previous {sub}.
Note that some codes in {sub} have a special meaning
sub-replace-special. For example, to replace something with
"\n" (two characters), use "\\\\n" or '\\n'.{pat} does not match in {string}, {string} is returned
unmodified.let &path = substitute(&path, ",\\=[^,]*$", "", "")echo substitute("testing", ".*", "\\U\\0", ""){sub} starts with "\=", the remainder is interpreted as

The syntax ID can be used with synIDattr() and
synIDtrans() to obtain syntax information about text.{col} is 1 for the leftmost column, {lnum} is 1 for the first
line. 'synmaxcol' applies, in a longer line zero is returned.
Note that when the position is after the last character,
that's where the cursor can be in Insert mode, synID() returns
zero. {lnum} is used like with getline().{trans} is TRUE, transparent items are reduced to the
item that they reveal. This is useful when wanting to know
the effective color. When {trans} is FALSE, the transparent
item is returned. This is useful when wanting to know which
syntax item is effective (e.g. inside parens).

region, 1 if it is. {lnum} is used like with getline().
2. The second item in the list is a string. If the first item
is 1, the second item contains the text which will be
displayed in place of the concealed text, depending on the
current setting of 'conceallevel' and 'listchars'.
3. The third and final item in the list is a number
representing the specific syntax region matched in the
line. When the character is not concealed the value is
zero. This allows detection of the beginning of a new
concealable region if there are two consecutive regions
with the same replacement character. For an example, if
the text is "123456" and both "23" and "45" are concealed
and replaced by the character "X", then:

like what synID() returns.
The first item in the List is the outer region, following are
items contained in that one. The last one is what synID()
returns, unless not the whole item is highlighted or it is a
transparent item.
This function is useful for debugging a syntax file.

-1 means forever. Default is 1.
If the timer causes an error three times in a
row the repeat is cancelled.func MyHandler(timer)
echo 'Handler called'
endfunc
let timer = timer_start(500, 'MyHandler',
\ {'repeat': 3}){time} (number)
{callback} (string|function)
{options} (table?)
any){timer}) timer_stop(){timer} is an ID returned by timer_start(), thus it must be a
Number. If {timer} does not exist there is no error.{timer} (integer)
any)any){expr}) tolower(){expr} (string)
string){expr}) toupper(){expr} (string)
string){src}, {fromstr}, {tostr}) tr(){src} string with all characters
which appear in {fromstr} replaced by the character in that
position in the {tostr} string. Thus the first character in
{fromstr} is translated into the first character in {tostr}
and so on. Exactly like the unix "tr" command.
This code also deals with multibyte characters properly.echo tr("hello there", "ht", "HT")echo tr("<blob>", "<>", "{}"){src} (string)
{fromstr} (string)
{tostr} (string)
string){text} [, {mask} [, {dir}]]) trim(){text} as a String where any character in {mask} is
removed from the beginning and/or end of {text}.{mask} is not given, or is an empty string, {mask} is all
characters up to 0x20, which includes Tab, space, NL and CR,
plus the non-breaking space character 0xa0.{dir} argument specifies where to remove the
characters:
0 remove from the beginning and end of {text}
1 remove only at the beginning of {text}
2 remove only at the end of {text}
When omitted both ends are trimmed.echo trim(" some text ")echo trim(" \r\t\t\r RESERVE \t\n\x0B\xA0") .. "_TAIL"echo trim("rm<Xrm<>X>rrm", "rm<>")echo trim(" vim ", " ", 2){text} (string)
{mask} (string?)
{dir} (0|1|2?)
string){expr}) trunc(){expr} as a Float (truncate towards zero).
{expr} must evaluate to a Float or a Number.
Returns 0.0 if {expr} is not a Float or a Number.
Examples:echo trunc(1.456)echo trunc(-5.456)echo trunc(4.0){expr} (number)
integer){expr}) type(){expr}.
Instead of using the number directly, it is better to use the
v:t_ variable that has the value:
Number: 0 v:t_number
String: 1 v:t_string
Funcref: 2 v:t_func
List: 3 v:t_list
Dictionary: 4 v:t_dict
Float: 5 v:t_float
Boolean: 6 v:t_bool (v:false and v:true)
Null: 7 (v:null)
Blob: 10 v:t_blob
For backward compatibility, this method can be used:if type(myvar) == type(0) | endif
if type(myvar) == type("") | endif
if type(myvar) == type(function("tr")) | endif
if type(myvar) == type([]) | endif
if type(myvar) == type({}) | endif
if type(myvar) == type(0.0) | endif
if type(myvar) == type(v:true) | endifif myvar is v:null | endifif exists('v:t_number') | endif{expr} (any)
integer){name}) undofile(){name} when writing. This uses the 'undodir'
option, finding directories that exist. It does not check if
the undo file exists.
{name} is always expanded to the full path, since that is what
is used internally.
If {name} is empty undofile() returns an empty string, since a
buffer without a file name will not write an undo file.
Useful in combination with :wundo and :rundo.{name} (string)
string){buf}]) undotree(){buf} is given. The
result is a dictionary with the following items:
"seq_last" The highest undo sequence number used.
"seq_cur" The sequence number of the current position in
the undo tree. This differs from "seq_last"
when some changes were undone.
"time_cur" Time last used for :earlier and related
commands. Use strftime() to convert to
something readable.
"save_last" Number of the last file write. Zero when no
write yet.
"save_cur" Number of the current position in the undo
tree.
"synced" Non-zero when the last undo block was synced.
This happens when waiting from input from the
user. See undo-blocks.
"entries" A list of dictionaries with information about
undo blocks.{buf} (integer|string?)
vim.fn.undotree.ret){list} [, {func} [, {dict}]]) uniq() E882
Remove second and succeeding copies of repeated adjacent

An {idx} in the middle of a UTF-8 sequence is rounded
downwards to the beginning of that sequence.{idx} bytes in {string}. If there are exactly {idx} bytes
the length of the string in UTF-16 code units is returned.echo utf16idx('a😊😊', 3) " returns 2

any){expr} [, {list} [, {winid}]]) virtcol(){expr}. That is, the last screen position
occupied by the character at that position, when the screen
would be of unlimited width. When there is a <Tab> at the
position, the returned Number will be the column at the end of
the <Tab>. For example, for a <Tab> in column 1, with 'ts'
set to 8, it returns 8. conceal is ignored.
For the byte position use col().{expr} see getpos() and col().
When {expr} is "$", it means the end of the cursor line, so
the result is the number of cells in the cursor line plus one.{expr} can be [lnum, col, off],
where "off" is the offset in screen columns from the start of
the character. E.g., a position within a <Tab> or after the
last character. When "off" is omitted zero is used. When
Virtual editing is active in the current mode, a position
beyond the end of the line can be returned. Also see

integer){expr}]) visualmode()CTRL-V character) for
character-wise, line-wise, or block-wise Visual mode
respectively.
Example:exe "normal " .. visualmode(){expr} is supplied and it evaluates to a non-zero Number or
a non-empty String, then the Visual mode will be cleared and
the old value is returned. See non-zero-arg.{expr} (boolean?)
string){timeout}, {condition} [, {interval}]) wait(){condition} evaluates to TRUE, where {condition}
is a Funcref or string containing an expression.{timeout} is the maximum waiting time in milliseconds, -1
means forever.{interval} milliseconds (default: 200).{timeout} (integer)

The window will temporarily be made the current window,
without triggering autocommands or changing directory. When
executing {command} autocommands will be triggered, this may
have unexpected side effects. Use :noautocmd if needed.
Example:call win_execute(winid, 'syntax enable')setwinvar() would not trigger
autocommands and not actually show syntax highlighting.{id} does not exist then no error is given and
an empty string is returned.{id} (integer)

With {win} this is the window number. The top window has
number 1.
Without {tab} use the current tab, otherwise the tab with
number {tab}. The first tab has number one.
Return zero if the window cannot be found.{win} (integer?)

integer){nr}, {offset}) win_move_separator(){nr}'s vertical separator (i.e., the right border)
by {offset} columns, as if being dragged by the mouse. {nr}
can be a window number or window-ID. A positive {offset}
moves right and a negative {offset} moves left. Moving a
window's vertical separator will change the width of the
window and the width of other windows adjacent to the vertical
separator. The magnitude of movement may be smaller than
specified (e.g., as a consequence of maintaining
'winminwidth'). Returns TRUE if the window can be found and
FALSE otherwise.
This will fail for the rightmost window and a full-width
window, since it has no separator on the right.
Only works for the current tab page. E1308{nr} (integer)
{offset} (integer)
any){nr}, {offset}) win_move_statusline(){nr}'s status line (i.e., the bottom border) by
{offset} rows, as if being dragged by the mouse. {nr} can be a
window number or window-ID. A positive {offset} moves down
and a negative {offset} moves up. Moving a window's status
line will change the height of the window and the height of
other windows adjacent to the status line. The magnitude of
movement may be smaller than specified (e.g., as a consequence
of maintaining 'winminheight'). Returns TRUE if the window can
be found and FALSE otherwise.
Only works for the current tab page.{nr} (integer)
{offset} (integer)
any){nr}) win_screenpos(){nr} as a list with two
numbers: [row, col]. The first window always has position
[1, 1], unless there is a tabline, then it is [2, 1].
{nr} can be the window number or the window-ID. Use zero
for the current window.
Returns [0, 0] if the window cannot be found.{nr} (integer)
any){nr}, {target} [, {options}]) win_splitmove(){target}, then move window {nr}
to a new split adjacent to {target}.
Unlike commands such as :split, no new windows are created
(the window-ID of window {nr} is unchanged after the move).{options} is a Dictionary with the following optional entries:
"vertical" When TRUE, the split is created vertically,
like with :vsplit.
"rightbelow" When TRUE, the split is made below or to the
right (if vertical). When FALSE, it is done
above or to the left (if vertical). When not
present, the values of 'splitbelow' and
'splitright' are used.{nr} (integer)
{target} (integer)
{options} (table?)
any){nr}) winbufnr(){nr}. {nr} can be the window number or
the window-ID.
When {nr} is zero, the number of the buffer in the current
window is returned.
When window {nr} doesn't exist, -1 is returned.
Example:echo "The file in the current window is " .. bufname(winbufnr(0)){nr} (integer)
integer)integer)string){nr}) winheight(){nr}.
{nr} can be the window number or the window-ID.
When {nr} is zero, the height of the current window is
returned. When window {nr} doesn't exist, -1 is returned.
An existing window always has a height of zero or more.
This excludes any window toolbar line.
Examples:echo "The current window has " .. winheight(0) .. " lines."{nr} (integer)
integer){tabnr}]) winlayout(){tabnr} use the current tabpage, otherwise the tabpage
with number {tabnr}. If the tabpage {tabnr} is not found,

any[])integer){arg}]) winnr(){arg} supports the following values:
$ the number of the last window (the window
count).
# the number of the last accessed window (where
CTRL-W_p goes to). If there is no previous
window or it is in another tab page 0 is
returned. May refer to the current window in
some cases (e.g. when evaluating 'statusline'
expressions).
{N}j the number of the Nth window below the
current window (where CTRL-W_j goes to).
{N}k the number of the Nth window above the current
window (where CTRL-W_k goes to).
{N}h the number of the Nth window left of the
current window (where CTRL-W_h goes to).
{N}l the number of the Nth window right of the
current window (where CTRL-W_l goes to).
The number can be used with CTRL-W_w and ":wincmd w"
:wincmd.
When {arg} is invalid an error is given and zero is returned.

{nr} can be the window number or the window-ID.
When {nr} is zero, the width of the current window is
returned. When window {nr} doesn't exist, -1 is returned.
