     If {msg} is empty then it is not used.  Do this to get the
     default message when passing the {lnum} argument.
     					*E1115*
     When {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*
     When {context} is present it is used as a pattern and matched
     against the context (script name or function name) where
     {lnum} is located in.

     Note that beeping is not considered an error, and some failing
     commands only beep.  Use |assert_beeps()| for those.

     The result is a Number, which is the byte index of the column
     position given with {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.

     With the optional {winid} argument the values are obtained for
     that window instead of the current window.

     To get the line number use |line()|.  To get both use
     |getpos()|.

     For the screen column position use |virtcol()|.  For the
     character position use |charcol()|.

     Note that only marks in the current file can be used.

     Examples: >vim
     	echo col(".")			" column of cursor
     	echo col("$")			" length of cursor line plus one
     	echo col("'t")			" column of mark t
     	echo col("'" .. markname)	" column of mark markname
     <
     The first column is 1.  Returns 0 if {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: >vim
     	imap <F2> <Cmd>echo col(".").."\n"<CR>
     <

     Set the matches for Insert mode completion.  Can only be used
     in Insert mode.  Typically invoked from a mapping with
     CTRL-R = (see |i_CTRL-R|), but may also be called from a
     |<Cmd>| mapping.  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: >vim

     confirm() offers the user a dialog, from which a choice can be
     made.  It returns the number of the choice.  For the first
     choice this is 1.

     {msg} is displayed in a dialog with {choices} as the
     alternatives.  When {choices} is missing or empty, "&OK" is
     used (and translated).
     {msg} is a String, use '\n' to include a newline.  Only on
     some systems the string is wrapped when it doesn't fit.

     {choices} is a String, with the individual choices separated
     by '\n', e.g. >vim
     	confirm("Save changes?", "&Yes\n&No\n&Cancel")
     <The letter after the '&' is the shortcut key for that choice.
     Thus you can type 'c' to select "Cancel".  The shortcut does
     not need to be the first letter: >vim
     	confirm("file has been modified", "&Save\nSave &All")
     <For the console, the first letter of each choice is used as
     the default shortcut key.  Case is ignored.

     The optional {type} String argument gives the type of dialog.
     It can be one of these values: "Error", "Question", "Info",
     "Warning" or "Generic".  Only the first character is relevant.
     When {type} is omitted, "Generic" is used.

     The optional {type} argument gives the type of dialog.  This
     is only used for the icon of the Win32 GUI.  It can be one of
     these values: "Error", "Question", "Info", "Warning" or
     "Generic".  Only the first character is relevant.
     When {type} is omitted, "Generic" is used.

     If the user aborts the dialog by pressing <Esc>, CTRL-C,
     or another valid interrupt key, confirm() returns 0.

     An example: >vim
        let choice = confirm("What do you want?",
     			\ "&Apples\n&Oranges\n&Bananas", 2)
        if choice == 0
     	echo "make up your mind!"

 dictwatcheradd = {

     Adds a watcher to a dictionary. A dictionary watcher is
     identified by three components:

     - A dictionary({dict});
     - A key pattern({pattern}).
     - A function({callback}).

     After this is called, every change on {dict} and on keys
     matching {pattern} will result in {callback} being invoked.

     For example, to watch all global variables: >vim
     	silent! call dictwatcherdel(g:, '*', 'OnDictChanged')
     	function! OnDictChanged(d,k,z)
     	  echomsg string(a:k) string(a:z)
     	endfunction
     	call dictwatcheradd(g:, '*', 'OnDictChanged')
     <
     For now {pattern} only accepts very simple patterns that can
     contain a "*" at the end of the string, in which case it will
     match every key that begins with the substring before the "*".
     That means if "*" is not the last character of {pattern}, only
     keys that are exactly equal as {pattern} will be matched.

     The {callback} receives three arguments:

     - The dictionary being watched.
     - The key which changed.
     - A dictionary containing the new and old values for the key.

     The type of change can be determined by examining the keys
     present on the third argument:

     - If contains both `old` and `new`, the key was updated.
     - If it contains only `new`, the key was added.
     - If it contains only `old`, the key was deleted.

     This function can be used by plugins to implement options with
     validation and parsing logic.

     This function checks if an executable with the name {expr}

     arguments.

     executable() uses the value of $PATH and/or the normal
     searchpath for programs.
     					*PATHEXT*
     On MS-Windows the ".exe", ".bat", etc. can optionally be
     included.  Then the extensions in $PATHEXT are tried.  Thus if
     "foo.exe" does not exist, "foo.exe.bat" can be found.  If
     $PATHEXT is not set then ".com;.exe;.bat;.cmd" is used.  A dot
     by itself can be used in $PATHEXT to try using the name
     without an extension.  When 'shell' looks like a Unix shell,
     then the name is also tried without adding an extension.
     On MS-Windows it only checks if the file exists and is not a
     directory, not if it's really executable.

     On MS-Windows an executable in the same directory as the Vim
     executable is always found (it's added to $PATH at |startup|).
     			*$NoDefaultCurrentDirectoryInExePath*
     On MS-Windows when using cmd.exe as 'shell' an executable in
     Vim's current working directory is also normally found, which
     can be disabled by setting the
     `$NoDefaultCurrentDirectoryInExePath` environment variable.
     This variable is always set by Vim when executing external
     commands (e.g., via |:!|, |:make|, or |system()|) for security
     reasons.

     The result is a Number:
     	1	exists

     	echo expand(expand("<cfile>"))
     <
     There cannot be white space between the variables and the
     following modifier.  The |fnamemodify()| function can be used
     to modify normal file names.

     When using '%' or '#', and the current or alternate file name
     is not defined, an empty string is used.  Using "%:p" in a
     buffer with no name, results in the current directory, with a
     '/' added.
     When 'verbose' is set then expanding '%', '#' and <> items
     will result in an error message if the argument cannot be
     expanded.

     When {string} does not start with '%', '#' or '<', it is
     expanded like a file name is expanded on the command line.
     'suffixes' and 'wildignore' are used, unless the optional
     {nosuf} argument is given and it is |TRUE|.
     Names for non-existing files are included.  The "**" item can
     be used to search in a directory tree.  For example, to find
     all "README" files in the current directory and below: >vim
     	echo expand("**/README")
     <
     expand() can also be used to expand variables and environment
     variables that are only known in a shell.  But this can be
     slow, because a shell may be used to do the expansion.  See
     |expr-env-expand|.
     The expanded variable is still handled like a list of file
     names.  When an environment variable cannot be expanded, it is
     left unchanged.  Thus ":echo expand('$FOOBAR')" results in
     "$FOOBAR".

     See |glob()| for finding existing files.  See |system()| for
     getting the raw output of an external command.

     Characters in {string} are queued for processing as if they
     come from a mapping or were typed by the user.

     By default the string is added to the end of the typeahead
     buffer, thus if a mapping is still being executed the
     characters come after them.  Use the 'i' flag to insert before
     other characters, they will be executed next, before any
     characters from a mapping.

     The function does not wait for processing of keys contained in
     {string}.

     To include special keys into {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.

     Return value is always 0.

     {expr2} must be a |string| or |Funcref|.

     If {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: >vim
     	call filter(mylist, 'v:val !~ "OLD"')
     <Removes the items where "OLD" appears. >vim
     	call filter(mydict, 'v:key >= 8')
     <Removes the items with a key below 8. >vim
     	call filter(var, 0)
     <Removes all the items, thus clears the |List| or |Dictionary|.

     Note that {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.

     If {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: >vim
     	func Odd(idx, val)
     	  return a:idx % 2 == 1
     	endfunc
     	call filter(mylist, function('Odd'))
     <It is shorter when using a |lambda|: >vim
     	call filter(myList, {idx, val -> idx * val <= 42})
     <If you do not use "val" you can leave it out: >vim
     	call filter(myList, {idx -> idx % 2 == 1})
     <
     For a |List| and a |Dictionary| the operation is done
     in-place.  If you want it to remain unmodified make a copy
     first: >vim
     	let l = filter(copy(mylist), 'v:val =~ "KEEP"')

     <Returns {expr1}, the |List| or |Dictionary| that was filtered,
     or a new |Blob| or |String|.
     When an error is encountered while evaluating {expr2} no

     {expr2} must be a |string| or |Funcref|.

     If {expr2} is a |string|, inside {expr2} |v:val| has the value
     of the current item.  For a |Dictionary| |v:key| has the key

     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.: >vim
     	let FuncWithArg = function(dict.Func, [arg])
     	let Broken = function(dict.Func, [arg], dict)
     <
     When using the Funcref the function will be found by {name},
     also when it was redefined later. Use |funcref()| to keep the
     same function.

     When {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.

     The arguments are passed to the function in front of other
     arguments, but after any argument from |method|.  Example: >vim

     	"...
     	endfunc
     	let Partial = function('Callback', ['two'])
     	"...
     	eval 'one'->Partial('three')
     <Invokes the function as with: >vim
     	call Callback('one', 'two', 'three')

     <The function() call can be nested to add more arguments to the
     Funcref.  The extra arguments are appended to the list of
     arguments.  Example: >vim
     	func Callback(arg1, arg2, name)
     	"...

     	let Func = function('Callback', ['one'])

     	call Callback('one', 'two', 'name')

     <The Dictionary is only useful when calling a "dict" function.
     In that case the {dict} is passed in as "self".  Example: >vim
     	function Callback() dict
     	   echo "called for " .. self.name
     	endfunction
     	"...
     	let context = {"name": "example"}

     			"keep": keep current cursor unchanged.
     			"msg": move cursor to message area.

     	number		If |TRUE|, return a Number when getting
     			a single character.
     			If |FALSE|, the return value is always
     			converted to a String, and an empty
     			String (instead of 0) is returned when
     			no character is available.

     			character if possible.  E.g., return
     			the same value for CTRL-I and <Tab>.
     			If |FALSE|, don't include modifiers in
     			the character.
     			(default: |TRUE|)

     When the user clicks a mouse button, the mouse event will be
     returned.  The position can then be found in |v:mouse_col|,
     |v:mouse_lnum|, |v:mouse_winid| and |v:mouse_win|.
     |getmousepos()| can also be used.  Mouse move events will be
     ignored.
     This example positions the mouse as it would normally happen: >vim
     	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
     <
     There is no prompt, you will somehow have to make clear to the
     user that a character has to be typed.  The screen is not
     redrawn, e.g. when resizing the window.

     There is no mapping for the character.
     Key codes are replaced, thus when the user presses the <Del>
     key you get the code for the <Del> key, not the raw character
     sequence.  Examples: >vim
     	getchar() == "\<Del>"
     	getchar() == "\<S-Left>"
     <This example redefines "f" to ignore case: >vim
     	nmap f :call FindChar()<CR>
     	function FindChar()
     	  let c = nr2char(getchar())
     	  while col('.') < col('$') - 1
     	    normal l
     	    if getline('.')[col('.') - 1] ==? c
     	      break

     If the optional {filtered} flag is set to 1, then 'wildignore'
     is applied to filter the results.  Otherwise all the matches

     If the 'wildoptions' option contains "fuzzy", then fuzzy
     matching is used to get the completion matches.  Otherwise
     regular expression matching is used.  Thus this function

     The "curswant" number is the preferred column when moving the
     cursor vertically.  After |$| command it will be a very large
     number equal to |v:maxcol|.  Also see |getcursorcharpos()| and

     The first "bufnum" item is always zero.  The byte position of

     Returns a |Dictionary| with the last known position of the

     Gets a position, where {expr} is one of:
         .	    Cursor position.
         $	    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	    End of the current Visual selection (unlike |'<|
     	    |'>| which give the previous, not current, Visual
     	    selection), or the cursor position if not in Visual
     	    mode.

     	    To get the current selected region: >vim
     	      let region = getregionpos(getpos('v'), getpos('.'))
     <
     	    Explanation: in Visual mode "v" and "." complement each
     	    other.  While "." refers to the cursor position, "v"
     	    refers to where |v_o| would move the cursor.  So you can
     	    use "v" and "." together to get the selected region.

     Note that if a mark in another file is used, the line number
     applies to that buffer.

     The result is a |List| with four numbers:
         [bufnum, lnum, col, off]
     "bufnum" is zero, unless a mark like '0 or 'A is used, then it
     is the buffer number of the mark.
     "lnum" and "col" are the position in the buffer.  The first
     column is 1.
     The "off" number is zero, unless 'virtualedit' is used.  Then
     it is the offset in screen columns from the start of the
     character.  E.g., a position within a <Tab> or after the last
     character.

     For getting the cursor position see |getcurpos()|.
     The column number in the returned List is the byte position
     within the line.  To get the character position in the line,
     use |getcharpos()|.

     The visual marks |'<| and |'>| refer to the beginning and end
     of the visual selection relative to the buffer.  Note that
     this differs from |setpos()|, where they are relative to the
     cursor position.

     Note that for '< and '> Visual mode matters: when it is "V"
     (visual line mode) the column of '< is zero and the column of
     '> is a large number equal to |v:maxcol|.
     A very large column number equal to |v:maxcol| can be returned,
     in which case it means "after the end of the line".
     If {expr} is invalid, returns a list with all zeros.

     This can be used to save and restore the position of a mark: >vim
     	let save_a_mark = getpos("'a")
     	" ...
     	call setpos("'a", save_a_mark)
     <

     Returns a |List| with all the current quickfix errors.  Each
     list item is a dictionary with these entries:
     	bufnr	number of buffer that has the file name, use
     		|bufname()| to get the name
     	module	module name
     	lnum	line number in the buffer (first line is 1)
     	end_lnum

     	col	column number (first column is 1)
     	end_col	end of column number if the item has range
     	vcol	|TRUE|: "col" is visual column
     		|FALSE|: "col" is byte index
     	nr	error number
     	pattern	search pattern used to locate the error
     	text	description of the error
     	type	type of the error, 'E', '1', etc.
     	valid	|TRUE|: recognized error message
     	user_data
     		custom data associated with the item, can be
     		any type.

     When there is no error list or it's empty, an empty list is
     returned.  Quickfix list entries with a non-existing buffer
     number are returned with "bufnr" set to zero (Note: some
     functions accept buffer number zero for the alternate buffer,
     you may need to explicitly check for zero).

     		the resulting entries.  Only a |List| type is
     		accepted.  The current quickfix list is not
     		modified.  See |quickfix-parse|.
     	nr	get information for this quickfix list; zero
     		means the current quickfix list and "$" means
     		the last quickfix list
     	qfbufnr number of the buffer displayed in the quickfix
     		window.  Returns 0 if the quickfix buffer is
     		not present.  See |quickfix-buffer|.
     	size	number of entries in the quickfix list
     	title	get the list title |quickfix-title|
     	winid	get the quickfix |window-ID|
     	all	all of the above quickfix properties
     Non-string items in {what} are ignored.  To get the value of a
     particular item, set it to zero.
     If "nr" is not present then the current quickfix list is used.
     If both "nr" and a non-zero "id" are specified, then the list
     specified by "id" is used.
     To get the number of lists in the quickfix stack, set "nr" to
     "$" in {what}.  The "nr" value in the returned dictionary
     contains the quickfix stack size.
     When "lines" is specified, all the other items except "efm"
     are ignored.  The returned dictionary contains the entry
     "items" with the list of entries.

     The returned dictionary contains the following entries:
     	changedtick	total number of changes made to the
     			list |quickfix-changedtick|
     	context	quickfix list context.  See |quickfix-context|
     		If not present, set to "".
     	id	quickfix list ID |quickfix-ID|.  If not

     See |getpos()| for the format of the list.  It's possible
     to specify positions from a different buffer, but please
     note the limitations at |getregion-notes|.

     The optional argument {opts} is a Dict and supports the
     following items:

     	type		Specify the region's selection type.
     			See |getregtype()| for possible values,
     			except that the width can be omitted
     			and an empty string cannot be used.
     			(default: "v")

     	exclusive	If |TRUE|, use exclusive selection
     			for the end position.
     			(default: follow 'selection')

     You can get the last selection type by |visualmode()|.
     If Visual mode is active, use |mode()| to get the Visual mode
     (e.g., in a |:vmap|).
     This function is useful to get text starting and ending in
     different columns, such as a |charwise-visual| selection.

     					*getregion-notes*
     Note that:
     - Order of {pos1} and {pos2} doesn't matter, it will always
       return content from the upper left position to the lower
       right position.
     - If 'virtualedit' is enabled and the region is past the end
       of the lines, resulting lines are padded with spaces.
     - If the region is blockwise and it starts or ends in the
       middle of a multi-cell character, it is not included but
       its selected part is substituted with spaces.
     - If {pos1} and {pos2} are not in the same buffer, an empty
       list is returned.
     - {pos1} and {pos2} must belong to a |bufloaded()| buffer.
     - It is evaluated in current window context, which makes a
       difference if the buffer is displayed in a window with
       different 'virtualedit' or 'list' values.
     - When specifying an exclusive selection and {pos1} and {pos2}
       are equal, the returned list contains a single character as
       if selection is inclusive, to match the behavior of an empty
       exclusive selection in Visual mode.

     receives user input as its only argument and must return
     a list of 3-tuples [hl_start_col, hl_end_col + 1, hl_group]
     where
     	hl_start_col is the first highlighted column,
     	hl_end_col is the last highlighted column (+ 1!),
     	hl_group is |:hi| group used for highlighting.
     			      *E5403* *E5404* *E5405* *E5406*
     Both hl_start_col and hl_end_col + 1 must point to the start
     of the multibyte character (highlighting must not break
     multibyte characters), hl_end_col + 1 may be equal to the
     input length.  Start column must be in range [0, len(input)),
     end column must be in range (hl_start_col, len(input)],
     sections must be ordered so that next hl_start_col is greater
     then or equal to previous hl_end_col.

     Example (try some input with parentheses): >vim

     Highlight function is called at least once for each new
     displayed input string, before command-line is redrawn.  It is
     expected that function is pure for the duration of one input()
     call, i.e. it produces the same output for the same input, so
     output may be memoized.  Function is run like under |:silent|
     modifier. If the function causes any errors, it will be
     skipped for the duration of the current input() call.

     Highlighting is disabled if command-line contains arabic
     characters.

     NOTE: This function must not be used in a startup file, for
     the versions that only run in GUI mode (e.g., the Win32 GUI).
     Note: When input() is called from within a mapping it will
     consume remaining characters from that mapping, because a
     mapping is handled like the characters were typed.
     Use |inputsave()| before input() and |inputrestore()|
     after input() to avoid that.  Another solution is to avoid
     that further characters follow in the mapping, e.g., by using
     |:execute| or |:normal|.

     Example with a mapping: >vim
     	nmap \x :call GetFoo()<CR>:exe "/" .. Foo<CR>
     	function GetFoo()
     	  call inputsave()

       cwd:	      (string, default=|current-directory|) Working
     	      directory of the job.
       detach:     (boolean) Detach the job process: it will not be
     	      killed when Nvim exits. If the process exits
     	      before Nvim, `on_exit` will be invoked.
       env:	      (dict) Map of environment variable name:value
     	      pairs extending (or replace with "clear_env")
     	      the current environment. |jobstart-env|
       height:     (number) Height of the `pty` terminal.
       |on_exit|:    (function) Callback invoked when the job exits.
       |on_stdout|:  (function) Callback invoked when the job emits
     	      stdout data.
       |on_stderr|:  (function) Callback invoked when the job emits
     	      stderr data.
       overlapped: (boolean) Sets FILE_FLAG_OVERLAPPED for the
     	      stdio passed to the child process. Only on
     	      MS-Windows; ignored on other platforms.
       pty:	      (boolean) Connect the job to a new pseudo
     	      terminal, and its streams to the master file
     	      descriptor. `on_stdout` receives all output,
     	      `on_stderr` is ignored. |terminal-start|
       rpc:	      (boolean) Use |msgpack-rpc| to communicate with
     	      the job over stdio. Then `on_stdout` is ignored,
     	      but `on_stderr` can still be used.
       stderr_buffered: (boolean) Collect data until EOF (stream closed)
     	      before invoking `on_stderr`. |channel-buffered|
       stdout_buffered: (boolean) Collect data until EOF (stream
     	      closed) before invoking `on_stdout`. |channel-buffered|
       stdin:      (string) Either "pipe" (default) to connect the
     	      job's stdin to a channel or "null" to disconnect
     	      stdin.
       term:	    (boolean) Spawns {cmd} in a new pseudo-terminal session
               connected to the current (unmodified) buffer. Implies "pty".
               Default "height" and "width" are set to the current window
               dimensions. |jobstart()|. Defaults $TERM to "xterm-256color".
       width:      (number) Width of the `pty` terminal.

     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.

     libcall() allows you to write your own 'plug-in' extensions to
     Vim without having to recompile the program.  It is NOT a
     means to call system functions!  If you try to do so Vim will
     very probably crash.

     For Win32, the functions you write must be placed in a DLL
     and use the normal C calling convention (NOT Pascal which is
     used in Windows System DLLs).  The function must take exactly
     one parameter, either a character pointer or a long integer,
     and must return a character pointer or NULL.  The character
     pointer returned must point to memory that will remain valid
     after the function has returned (e.g. in static data in the
     DLL).  If it points to allocated memory, that memory will
     leak away.  Using a static buffer in the function should work,
     it's then freed when the DLL is unloaded.

     WARNING: If the function returns a non-valid pointer, Vim may
     crash!	This also happens if the function returns a number,
     because Vim thinks it's a pointer.
     For Win32 systems, {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.
     For Unix: When compiling your own plugins, remember that the
     object code must be compiled as position-independent ('PIC').

     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} must be a |String| or |Funcref|.

     If {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: >vim
     	call map(mylist, '"> " .. v:val .. " <"')
     <This puts "> " before and " <" after each item in "mylist".

     Note that {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

     If {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": >vim
     	func KeyValue(key, val)
     	  return a:key .. '-' .. a:val
     	endfunc
     	call map(myDict, function('KeyValue'))

     <If you do not use "val" you can leave it out: >vim
     	call map(myDict, {key -> 'item: ' .. key})
     <If you do not use "key" you can use a short name: >vim
     	call map(myDict, {_, val -> 'item: ' .. val})

       "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.
     	     See |maplist()| for usage examples.  The values
     	     are from src/nvim/state_defs.h and may change in

     String is returned.  If there is one, the RHS of that mapping

     |mapping-dict|'s "mode_bits" can simplify this.  For example,
     the mode_bits for Normal, Insert or Command-line modes are

     can do: >vim

     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*

     In the first form, {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: >vim
     	let save_map = maparg('K', 'n', 0, 1)
     	nnoremap K somethingelse
     	" ...
     	call mapset('n', 0, save_map)
     <Note that if you are going to replace a map in several modes,
     e.g. with `:map!`, you need to save/restore the mapping for
     all of them, when they might differ.

     In the second form, with {dict} as the only argument, mode
     and abbr are taken from the dict.

     				\ {_, m -> m.lhs == 'K'})
     	nnoremap K somethingelse

     When {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.

     Otherwise, {expr} is used as a String.  The result is a
     Number, which gives the index (byte offset) in {expr} where
     {pat} matches.

     A match at the first character or |List| item returns zero.
     If there is no match -1 is returned.

     For getting submatches see |matchlist()|.
     Example: >vim
     	echo match("testing", "ing")	" results in 4
     	echo match([1, 'x'], '\a')	" results in 1
     <See |string-match| for how {pat} is used.
     					*strpbrk()*
     Vim doesn't have a strpbrk() function.  But you can do: >vim
     	let sepidx = match(line, '[.,;: \t]')
     <					*strcasestr()*
     Vim doesn't have a strcasestr() function.  But you can add
     "\c" to the pattern to ignore case: >vim
     	let idx = match(haystack, '\cneedle')
     <
     If {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: >vim
     	echo match("testing", "ing", 2)
     <result is again "4". >vim
     	echo match("testing", "ing", 4)
     <result is again "4". >vim
     	echo match("testing", "t", 2)
     <result is "3".
     For a String, if {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.

     When {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: >vim
     	echo match("testing", "..", 0, 2)
     <In a |List| the search continues in the next item.
     Note that when {count} is added the way {start} works changes,
     see above.

     				*match-pattern*
     See |pattern| for the patterns that are accepted.
     The 'ignorecase' option is used to set the ignore-caseness of
     the pattern.  'smartcase' is NOT used.  The matching is always
     done like 'magic' is set and 'cpoptions' is empty.
     Note that a match at the start is preferred, thus when the
     pattern is using "*" (any number of matches) it tends to find
     zero matches at the start instead of a number of matches
     further down in the text.

     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.

     The optional {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.

     The optional {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.

     The optional {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:

     	conceal	    Special character to show instead of the
     		    match (only for |hl-Conceal| highlighted
     		    matches, see |:syn-cchar|)
     	window	    Instead of the current window use the
     		    window with this number or window ID.

     The number of matches is not limited, as it is the case with
     the |:match| commands.

     Returns -1 on error.

     Example: >vim
     	highlight MyGroup ctermbg=green guibg=green
     	let m = matchadd("MyGroup", "TODO")
     <Deletion of the pattern: >vim

     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:
     - A number.  This whole line will be highlighted.  The first
       line has number 1.
     - A list with one number, e.g., [23].  The whole line with
       this number will be highlighted.
     - A list with two numbers, e.g., [23, 11].  The first number
       is the line number, the second one is the column number
       (first column is 1, the value must correspond to the byte
       index as |col()| would return).  The character at this
       position will be highlighted.
     - A list with three numbers, e.g., [23, 11, 3].  As above, but
       the third number gives the length of the highlight in bytes.

     Entries with zero and negative line numbers are silently
     ignored, as well as entries with negative column numbers and
     lengths.

     Returns -1 on error.

     Example: >vim

     Returns the |List| of matches in lines from {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}.

     The {dict} argument supports following items:
         submatches	include submatch information (|/\(|)

     For each match, a |Dict| with the following items is returned:
         byteidx	starting byte index of the match
         lnum	line number where there is a match
         text	matched string
     Note that there can be multiple matches in a single line.

     This function works only for loaded buffers.  First call
     |bufload()| if needed.

     See |match-pattern| for information about the effect of some
     option settings on the pattern.

     When {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.

     Examples: >vim
         " Assuming line 3 in buffer 5 contains "a"
         echo matchbufline(5, '\<\k\+\>', 3, 3)
     <    `[{'lnum': 3, 'byteidx': 0, 'text': 'a'}]` >vim
         " Assuming line 4 in buffer 10 contains "tik tok"
         echo matchbufline(10, '\<\k\+\>', 1, 4)
     <    `[{'lnum': 4, 'byteidx': 0, 'text': 'tik'}, {'lnum': 4, 'byteidx': 4, 'text': 'tok'}]`

     If {submatch} is present and is v:true, then submatches like
     "\1", "\2", etc. are also returned.  Example: >vim
         " Assuming line 2 in buffer 2 contains "acd"

     The "submatches" List always contains 9 items.  If a submatch
     is not found, then an empty string is returned for that
     submatch.

     If {list} is a list of strings, then returns a |List| with all
     the strings in {list} that fuzzy match {str}.  The strings in
     the returned list are sorted based on the matching score.

     The optional {dict} argument always supports the following
     items:
         matchseq	When this item is present return only matches
     		that contain the characters in {str} in the
     		given sequence.
         limit	Maximum number of matches in {list} to be
     		returned.  Zero means no limit.

     If {list} is a list of dictionaries, then the optional {dict}
     argument supports the following additional items:
         key		Key of the item which is fuzzy matched against
     		{str}.  The value of this item should be a
     		string.
         text_cb	|Funcref| that will be called for every item
     		in {list} to get the text for fuzzy matching.
     		This should accept a dictionary item as the
     		argument and return the text for that item to
     		use for fuzzy matching.

     {str} is treated as a literal string and regular expression
     matching is NOT supported.  The maximum supported {str} length
     is 256.

     When {str} has multiple words each separated by white space,
     then the list of strings that have all the words is returned.

     If there are no matching strings or there is an error, then an
     empty list is returned.  If length of {str} is greater than
     256, then returns an empty list.

     When {limit} is given, matchfuzzy() will find up to this
     number of matches in {list} and return them in sorted order.

     Refer to |fuzzy-matching| for more information about fuzzy
     matching strings.

     Example: >vim

     some directories may already exist.  Only the first one that
     is created and what it contains is scheduled to be deleted.
     E.g. when using: >vim

     scheduled for deletion, like with: >vim

     Limitations:
     1. Mapping ordering is not preserved unless messagepack
        mapping is dumped using generic mapping
        (|msgpack-special-map|).
     2. Since the parser aims to preserve all data untouched
        (except for 1.) some strings are parsed to
        |msgpack-special-dict| format which is not convenient to
        use.
     					*msgpack-special-dict*
     Some messagepack strings may be parsed to special
     dictionaries. Special dictionaries are dictionaries which

     1. Contain exactly two keys: `_TYPE` and `_VAL`.
     2. `_TYPE` key is one of the types found in |v:msgpack_types|
        variable.
     3. Value for `_VAL` has the following format (Key column
        contains name of the key from |v:msgpack_types|):

     Key	Value ~
     nil	Zero, ignored when dumping.  Not returned by
     	|msgpackparse()| since |v:null| was introduced.
     boolean	One or zero.  When dumping it is only checked that
     	value is a |Number|.  Not returned by |msgpackparse()|
     	since |v:true| and |v:false| were introduced.
     integer	|List| with four numbers: sign (-1 or 1), highest two
     	bits, number with bits from 62nd to 31st, lowest 31
     	bits. I.e. to get actual number one will need to use
     	code like >
     		_VAL[0] * ((_VAL[1] << 62)
     		           & (_VAL[2] << 31)
     		           & _VAL[3])
     <	Special dictionary with this type will appear in
     	|msgpackparse()| output under one of the following
     	circumstances:
     	1. |Number| is 32-bit and value is either above
     	   INT32_MAX or below INT32_MIN.
     	2. |Number| is 64-bit and value is above INT64_MAX. It
     	   cannot possibly be below INT64_MIN because msgpack
     	   C parser does not support such values.
     float	|Float|. This value cannot possibly appear in
     	|msgpackparse()| output.
     string	|String|, or |Blob| if binary string contains zero
     	byte. This value cannot appear in |msgpackparse()|
     	output since blobs were introduced.
     array	|List|. This value cannot appear in |msgpackparse()|
     	output.
     					*msgpack-special-map*
     map	|List| of |List|s with two items (key and value) each.
     	This value will appear in |msgpackparse()| output if
     	parsed mapping contains one of the following keys:
     	1. Any key that is not a string (including keys which
     	   are binary strings).
     	2. String with NUL byte inside.
     	3. Duplicate key.

     Conversion specifications start with '%' and end with the

     	% [pos-argument] [flags] [field-width] [.precision] type

     pos-argument
     	At most one positional argument specifier.  These take
     	the form {n$}, where n is >= 1.

     flags
     	Zero or more of the following flags:

         #	      The value should be converted to an "alternate
     	      form".  For c, d, and s conversions, this option
     	      has no effect.  For o conversions, the precision
     	      of the number is increased to force the first
     	      character of the output string to a zero (except
     	      if a zero value is printed with an explicit
     	      precision of zero).
     	      For x and X conversions, a non-zero result has
     	      the string "0x" (or "0X" for X conversions)
     	      prepended to it.

         0 (zero)  Zero padding.  For all conversions the converted
     	      value is padded on the left with zeros rather
     	      than blanks.  If a precision is given with a
     	      numeric conversion (d, o, x, and X), the 0 flag
     	      is ignored.

         -	      A negative field width flag; the converted value
     	      is to be left adjusted on the field boundary.
     	      The converted value is padded on the right with
     	      blanks, rather than on the left with blanks or
     	      zeros.  A - overrides a 0 if both are given.

         ' ' (space)  A blank should be left before a positive
     	      number produced by a signed conversion (d).

         +	      A sign must always be placed before a number
     	      produced by a signed conversion.  A + overrides
     	      a space if both are used.

     field-width
     	An optional decimal digit string specifying a minimum
     	field width.  If the converted value has fewer bytes
     	than the field width, it will be padded with spaces on
     	the left (or right, if the left-adjustment flag has
     	been given) to fill out the field width.  For the S
     	conversion the count is in cells.

     .precision
     	An optional precision, in the form of a period '.'
     	followed by an optional digit string.  If the digit
     	string is omitted, the precision is taken as zero.
     	This gives the minimum number of digits to appear for
     	d, o, x, and X conversions, the maximum number of
     	bytes to be printed from a string for s conversions,
     	or the maximum number of cells to be printed from a
     	string for S conversions.
     	For floating point it is the number of digits after
     	the decimal point.

     type
     	A character that specifies the type of conversion to
     	be applied, see below.

     A field width or precision, or both, may be indicated by an
     asterisk "*" instead of a digit string.  In this case, a
     Number argument supplies the field width or precision.  A
     negative field width is treated as a left adjustment flag
     followed by a positive field width; a negative precision is
     treated as though it were missing.  Example: >vim
     	echo printf("%d: %.*s", nr, width, line)
     <This limits the length of the text used from "line" to
     "width" bytes.

     If the argument to be formatted is specified using a
     positional argument specifier, and a '*' is used to indicate
     that a number argument is to be used to specify the width or
     precision, the argument(s) to be used must also be specified
     using a {n$} positional argument specifier.  See |printf-$|.

     The conversion specifiers and their meanings are:

     		*printf-d* *printf-b* *printf-B* *printf-o* *printf-x* *printf-X*
     dbBoxX	The Number argument is converted to signed decimal (d),
     	unsigned binary (b and B), unsigned octal (o), or
     	unsigned hexadecimal (x and X) notation.  The letters
     	"abcdef" are used for x conversions; the letters
     	"ABCDEF" are used for X conversions.  The precision, if
     	any, gives the minimum number of digits that must
     	appear; if the converted value requires fewer digits, it
     	is padded on the left with zeros.  In no case does a
     	non-existent or small field width cause truncation of a
     	numeric field; if the result of a conversion is wider
     	than the field width, the field is expanded to contain
     	the conversion result.
     	The 'h' modifier indicates the argument is 16 bits.
     	The 'l' modifier indicates the argument is a long
     	integer.  The size will be 32 bits or 64 bits
     	depending on your platform.
     	The "ll" modifier indicates the argument is 64 bits.
     	The b and B conversion specifiers never take a width
     	modifier and always assume their argument is a 64 bit
     	integer.
     	Generally, these modifiers are not useful.  They are
     	ignored when type is known from the argument.

     i	alias for d
     D	alias for ld
     U	alias for lu
     O	alias for lo

     					*printf-c*
     c	The Number argument is converted to a byte, and the
     	resulting character is written.

     					*printf-s*
     s	The text of the String argument is used.  If a
     	precision is specified, no more bytes than the number
     	specified are used.
     	If the argument is not a String type, it is
     	automatically converted to text with the same format
     	as ":echo".
     					*printf-S*
     S	The text of the String argument is used.  If a
     	precision is specified, no more display cells than the
     	number specified are used.

     					*printf-f* *E807*
     f F	The Float argument is converted into a string of the
     	form 123.456.  The precision specifies the number of
     	digits after the decimal point.  When the precision is
     	zero the decimal point is omitted.  When the precision
     	is not specified 6 is used.  A really big number
     	(out of range or dividing by zero) results in "inf"
     	 or "-inf" with %f (INF or -INF with %F).
     	 "0.0 / 0.0" results in "nan" with %f (NAN with %F).
     	Example: >vim
     		echo printf("%.2f", 12.115)
     <		12.12
     	Note that roundoff depends on the system libraries.
     	Use |round()| when in doubt.

     					*printf-e* *printf-E*
     e E	The Float argument is converted into a string of the
     	form 1.234e+03 or 1.234E+03 when using 'E'.  The
     	precision specifies the number of digits after the
     	decimal point, like with 'f'.

     					*printf-g* *printf-G*
     g G	The Float argument is converted like with 'f' if the
     	value is between 0.001 (inclusive) and 10000000.0
     	(exclusive).  Otherwise 'e' is used for 'g' and 'E'
     	for 'G'.  When no precision is specified superfluous
     	zeroes and '+' signs are removed, except for the zero
     	immediately after the decimal point.  Thus 10000000.0
     	results in 1.0e7.

     					*printf-%*
     %	A '%' is written.  No argument is converted.  The
     	complete conversion specification is "%%".

     When a Number argument is expected a String argument is also
     accepted and automatically converted.
     When a Float or String argument is expected a Number argument
     is also accepted and automatically converted.
     Any other argument type results in an error message.

     					*E766* *E767*
     The number of {exprN} arguments must exactly match the number
     of "%" items.  If there are not sufficient or too many
     arguments an error is given.  Up to 18 arguments can be used.

     					*printf-$*
     In certain languages, error and informative messages are
     more readable when the order of words is different from the
     corresponding message in English.  To accommodate translations
     having a different word order, positional arguments may be
     used to indicate this.  For instance: >vim

         #, c-format
         msgid "%s returning %s"
         msgstr "waarde %2$s komt terug van %1$s"
     <
     In this example, the sentence has its 2 string arguments
     reversed in the output. >vim

         echo printf(
     	"In The Netherlands, vim's creator's name is: %1$s %2$s",
     	"Bram", "Moolenaar")
     <    In The Netherlands, vim's creator's name is: Bram Moolenaar >vim

         echo printf(
     	"In Belgium, vim's creator's name is: %2$s %1$s",
     	"Bram", "Moolenaar")
     <    In Belgium, vim's creator's name is: Moolenaar Bram

     Width (and precision) can be specified using the '*'
     specifier.  In this case, you must specify the field width
     position in the argument list. >vim

         echo printf("%1$*2$.*3$d", 1, 2, 3)
     <    001 >vim
         echo printf("%2$*3$.*1$d", 1, 2, 3)
     <      2 >vim
         echo printf("%3$*1$.*2$d", 1, 2, 3)
     <    03 >vim
         echo printf("%1$*2$.*3$g", 1.4142, 2, 3)
     <    1.414

     You can mix specifying the width and/or precision directly
     and via positional arguments: >vim

         echo printf("%1$4.*2$f", 1.4142135, 6)
     <    1.414214 >vim
         echo printf("%1$*2$.4f", 1.4142135, 6)
     <    1.4142 >vim
         echo printf("%1$*2$.*3$f", 1.4142135, 6, 2)
     <      1.41

     You will get an overflow error |E1510|, when the field-width
     or precision will result in a string longer than 1 MB
     (1024*1024 = 1048576) chars.

     					*E1500*
     You cannot mix positional and non-positional arguments: >vim
         echo printf("%s%1$s", "One", "Two")
         " E1500: Cannot mix positional and non-positional arguments:
         " %s%1$s
     <
     					*E1501*
     You cannot skip a positional argument in a format string: >vim
         echo printf("%3$s%1$s", "One", "Two", "Three")
         " E1501: format argument 2 unused in $-style format:
         " %3$s%1$s
     <
     					*E1502*
     You can re-use a [field-width] (or [precision]) argument: >vim
         echo printf("%1$d at width %2$d is: %1$0*2$d", 1, 2)
         " 1 at width 2 is: 01
     <
     However, you can't use it as a different type: >vim
         echo printf("%1$d at width %2$ld is: %1$0*2$d", 1, 2)
         " E1502: Positional argument 2 used as field width reused as
         " different type: long int/int
     <
     					*E1503*
     When a positional argument is used, but not the correct number
     or arguments is given, an error is raised: >vim
         echo printf("%1$d at width %2$d is: %1$0*2$.*3$d", 1, 2)
         " E1503: Positional argument 3 out of bounds: %1$d at width
         " %2$d is: %1$0*2$.*3$d
     <
     Only the first error is reported: >vim
         echo printf("%1$0*2$.*3$d %4$d", 1, 2)
         " E1503: Positional argument 3 out of bounds: %1$0*2$.*3$d
         " %4$d
     <
     					*E1504*
     A positional argument can be used more than once: >vim
         echo printf("%1$s %2$s %1$s", "One", "Two")
         " One Two One
     <
     However, you can't use a different type the second time: >vim
         echo printf("%1$s %2$s %1$d", "One", "Two")
         " E1504: Positional argument 1 type used inconsistently:
         " int/string
     <
     					*E1505*
     Various other errors that lead to a format string being
     wrongly formatted lead to: >vim
         echo printf("%1$d at width %2$d is: %01$*2$.3$d", 1, 2)
         " E1505: Invalid format specifier: %1$d at width %2$d is:
         " %01$*2$.3$d
     <
     					*E1507*
     This internal error indicates that the logic to parse a
     positional format argument ran into a problem that couldn't be
     otherwise reported.  Please file a bug against Vim if you run
     into this, copying the exact format string and parameters that
     were used.

     The callback is invoked when pressing Enter.  The current

     All NUL characters are replaced with a NL character.
     When {type} contains "b" binary mode is used:
     - When the last line ends in a NL an extra empty list item is
       added.
     - No CR characters are removed.

     starts in column zero and then matches before the cursor are
     skipped.  When the 'c' flag is present in 'cpo' the next
     search starts after the match.  Without the 'c' flag the next
     search starts one column after the start of the match.  This
     matters for overlapping matches.  See |cpo-c|.  You can also
     insert "\ze" to change where the match ends, see  |/\ze|.

     When searching backwards and the 'z' flag is given then the
     search starts in column zero, thus no match in the current
     line will be found (unless wrapping around the end of the
     file).

     When the {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: >vim
     	let match = search('(', 'b', line("w0"))
     	let end = search('END', '', line("w$"))
     <When {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.

     When the {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.

     Note: the timeout is only considered when searching, not
     while evaluating the {skip} expression.

     If the {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()-sub-match*
     With the 'p' flag the returned value is one more than the
     first sub-match in \(\).  One if none of them matched but the
     whole pattern did match.
     To get the column number too use |searchpos()|.

     The cursor will be positioned at the match, unless the 'n'
     flag is used.

     Example (goes over all files in the argument list): >vim
         let n = 1
         while n <= argc()	    " loop over all files in arglist
           exe "argument " .. n
           " start at the last char in the file and wrap for the
           " first search to find match at start of file
           normal G$
           let flags = "w"
           while search("foo", flags) > 0
             s/foo/bar/g
             let flags = "W"
           endwhile
           update		    " write the file if modified
           let n = n + 1
         endwhile
     <
     Example for using some flags: >vim
         echo search('\<if\|\(else\)\|\(endif\)', 'ncpe')
     <This will search for the keywords "if", "else", and "endif"
     under or after the cursor.  Because of the 'p' flag, it
     returns 1, 2, or 3 depending on which keyword is found, or 0
     if the search fails.  With the cursor on the first word of the
     line:
         if (foo == 0) | let foo = foo + 1 | endif ~
     the function returns 1.  Without the 'c' flag, the function
     finds the "endif" and returns 3.  The same thing happens
     without the 'e' flag if the cursor is on the "f" of "if".
     The 'n' flag tells the function not to move the cursor.

     To get the last search count when |n| or |N| was pressed, call
     this function with `recompute: 0` .  This sometimes returns
     wrong information because of 'maxsearchcount'.
     If the count exceeded 'maxsearchcount', the result must be
     'maxsearchcount' + 1.  If you want to get correct information,
     specify `recompute: 1`: >vim

     	" result == 'maxsearchcount' + 1 when many matches
     	let result = searchcount(#{recompute: 0})

     	" 'hlsearch' was on
     	" let &statusline ..=
     	" \   '%{v:hlsearch ? LastSearchCount() : ""}'
     <
     You can also update the search count, which can be useful in a
     |CursorMoved| or |CursorMovedI| autocommand: >vim

     	autocmd CursorMoved,CursorMovedI *
     	  \ let s:searchcount_timer = timer_start(

     Search for the declaration of {name}.

     With a non-zero {global} argument it works like |gD|, find
     first match in the file.  Otherwise it works like |gd|, find
     first match in the function.

     With a non-zero {thisblock} argument matches in a {} block
     that ends before the cursor position are ignored.  Avoids
     finding variable declarations only valid in another scope.

     Moves the cursor to the found match.
     Returns zero for success, non-zero for failure.

     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
     direction, but only when not in a nested start-end pair.  A
     typical use is: >vim
     	echo searchpair('\<if\>', '\<else\>', '\<endif\>')
     <By leaving {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.

     When a match for {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
     match is to be skipped.  E.g., because it is inside a comment
     or a string.
     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.
     Anything else makes the function fail.

     For {stopline} and {timeout} see |search()|.

     The value of 'ignorecase' is used.  'magic' is ignored, the
     patterns are used like it's on.

     The search starts exactly at the cursor.  A match with
     {start}, {middle} or {end} at the next character, in the
     direction of searching, is the first one found.  Example: >vim
     	if 1
     	  if 2
     	  endif 2
     	endif 1
     <When starting at the "if 2", with the cursor on the "i", and
     searching forwards, the "endif 2" is found.  When starting on
     the character just before the "if 2", the "endif 1" will be
     found.  That's because the "if 2" will be found first, and
     then this is considered to be a nested if/endif from "if 2" to
     "endif 2".
     When searching backwards and {end} is more than one character,
     it may be useful to put "\zs" at the end of the pattern, so
     that when the cursor is inside a match with the end it finds
     the matching start.

     Example, to find the "endif" command in a Vim script: >vim

     	echo searchpair('\<if\>', '\<el\%[seif]\>', '\<en\%[dif]\>', 'W',
     	\ 'getline(".") =~ "^\\s*\""')

     <The cursor must be at or after the "if" for which a match is
     to be found.  Note that single-quote strings are used to avoid
     having to double the backslashes.  The skip expression only
     catches comments at the start of a line, not after a command.
     Also, a word "en" or "if" halfway through a line is considered
     a match.
     Another example, to search for the matching "{" of a "}": >vim

     	echo searchpair('{', '', '}', 'bW')

     <This works when the cursor is at or before the "}" for which a
     match is to be found.  To reject matches that syntax
     highlighting recognized as strings: >vim

     	echo searchpair('{', '', '}', 'bW',

     {low} and {high} can be the same, in which case this refers to
     one character.  Otherwise it is the range of characters from
     {low} to {high} (inclusive).		*E1111* *E1114*
     Only characters with value 0x80 and higher can be used.

     {width} must be either 1 or 2, indicating the character width
     in screen cells.			*E1112*
     An error is given if the argument is invalid, also when a
     range overlaps with another.		*E1113*

     If the new value causes 'fillchars' or 'listchars' to become
     invalid it is rejected and an error is given.

     To clear the overrides pass an empty {list}: >vim
        call setcellwidths([])

     <You can use the script $VIMRUNTIME/scripts/emoji_list.lua to see
     the effect for known emoji characters.  Move the cursor
     through the text to check if the cell widths of your terminal
     match with what Vim knows about each emoji.  If it doesn't
     look right you need to adjust the {list} argument.

         [bufnum, lnum, col, off]
         [bufnum, lnum, col, off, curswant]

     "bufnum" is the buffer number.	Zero can be used for the
     current buffer.  When setting an uppercase mark "bufnum" is
     used for the mark position.  For other marks it specifies the
     buffer to set the mark in.  You can use the |bufnr()| function
     to turn a file name into a buffer number.
     For setting the cursor and the ' mark "bufnum" is ignored,
     since these are associated with a window, not a buffer.
     Does not change the jumplist.

     "lnum" and "col" are the position in the buffer.  The first
     column is 1.  Use a zero "lnum" to delete a mark.  If "col" is
     smaller than 1 then 1 is used.  To use the character count
     instead of the byte count, use |setcharpos()|.

     The "off" number is only used when 'virtualedit' is set.  Then
     it is the offset in screen columns from the start of the
     character.  E.g., a position within a <Tab> or after the last
     character.

     The "curswant" number is only used when setting the cursor
     position.  It sets the preferred column for when moving the
     cursor vertically.  When the "curswant" number is missing the
     preferred column is not set.  When it is present and setting a
     mark position it is not used.

     Note that for |'<| and |'>| changing the line number may
     result in the marks to be effectively swapped, so that |'<| is
     always before |'>|.

     The visual marks |'<| and |'>| refer to the beginning and end
     of the visual selection relative to the cursor position.
     Note that this differs from |getpos()|, where they are
     relative to the buffer.

     Returns 0 when the position could be set, -1 otherwise.
     An error message is given if {expr} is invalid.

     Also see |setcharpos()|, |getpos()| and |getcurpos()|.

     This does not restore the preferred column for moving
     vertically; if you set the cursor position with this, |j| and
     |k| motions will jump to previous columns!  Use |cursor()| to
     also set the preferred column.  Also see the "curswant" key in
     |winrestview()|.

     					*setqflist-what*
     When {what} is not present, the items in {list} are used.
     Each item must be a dictionary.  Non-dictionary items in
     {list} are ignored.  Each dictionary item can contain the
     following entries:

         bufnr	buffer number; must be the number of a valid
     		buffer
         filename	name of a file; only used when "bufnr" is not
     		present or it is invalid.
         module	name of a module; if given it will be used in
     		quickfix error window instead of the filename.
         lnum	line number in the file
         end_lnum	end of lines, if the item spans multiple lines
         pattern	search pattern used to locate the error
         col		column number
         vcol	when non-zero: "col" is visual column
     		when zero: "col" is byte index
         end_col	end column, if the item spans multiple columns
         nr		error number
         text	description of the error
         type	single-character error type, 'E', 'W', etc.
         valid	recognized error message
         user_data
     		custom data associated with the item, can be
     		any type.

     The "col", "vcol", "nr", "type" and "text" entries are
     optional.  Either "lnum" or "pattern" entry can be used to
     locate a matching error line.
     If the "filename" and "bufnr" entries are not present or
     neither the "lnum" or "pattern" entries are present, then the
     item will not be handled as an error line.
     If both "pattern" and "lnum" are present then "pattern" will
     be used.
     If the "valid" entry is not supplied, then the valid flag is
     set when "bufnr" is a valid buffer or "filename" exists.
     If you supply an empty {list}, the quickfix list will be
     cleared.
     Note that the list is not exactly the same as what
     |getqflist()| returns.

     {action} values:		*setqflist-action* *E927*
     'a'	The items from {list} are added to the existing
     	quickfix list.  If there is no existing list, then a
     	new list is created.

     'r'	The items from the current quickfix list are replaced
     	with the items from {list}.  This can also be used to
     	clear the list: >vim
     		call setqflist([], 'r')
     <
     'u'	Like 'r', but tries to preserve the current selection
     	in the quickfix list.
     'f'	All the quickfix lists in the quickfix stack are
     	freed.

     If {action} is not present or is set to ' ', then a new list
     is created.  The new quickfix list is added after the current
     quickfix list in the stack and all the following lists are
     freed.  To add a new quickfix list at the end of the stack,
     set "nr" in {what} to "$".

     The following items can be specified in dictionary {what}:
         context	quickfix list context.  See |quickfix-context|
         efm		errorformat to use when parsing text from
     		"lines".  If this is not present, then the
     		'errorformat' option value is used.
     		See |quickfix-parse|
         id		quickfix list identifier |quickfix-ID|
         idx		index of the current entry in the quickfix
     		list specified by "id" or "nr".  If set to
     		'$', then the last entry in the list is set as
     		the current entry.  See |quickfix-index|
         items	list of quickfix entries.  Same as the {list}
     		argument.
         lines	use 'errorformat' to parse a list of lines and
     		add the resulting entries to the quickfix list
     		{nr} or {id}.  Only a |List| value is supported.
     		See |quickfix-parse|
         nr		list number in the quickfix stack; zero
     		means the current quickfix list and "$" means
     		the last quickfix list.
         quickfixtextfunc
     		function to get the text to display in the
     		quickfix window.  The value can be the name of
     		a function or a funcref or a lambda.  Refer to
     		|quickfix-window-function| for an explanation
     		of how to write the function and an example.
         title	quickfix list title text.  See |quickfix-title|
     Unsupported keys in {what} are ignored.
     If the "nr" item is not present, then the current quickfix
     list is modified.  When creating a new quickfix list, "nr" can
     be set to a value one greater than the quickfix stack size.
     When modifying a quickfix list, to guarantee that the correct
     list is modified, "id" should be used instead of "nr" to
     specify the list.

     Examples (See also |setqflist-examples|): >vim
        call setqflist([], 'r', {'title': 'My search'})
        call setqflist([], 'r', {'nr': 2, 'title': 'Errors'})
        call setqflist([], 'a', {'id':qfid, 'lines':["F1:10:L10"]})
     <
     Returns zero for success, -1 for failure.

     This function can be used to create a quickfix list
     independent of the 'errorformat' setting.  Use a command like
     `:cc 1` to jump to the first position.

     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}.

     If {options} contains no register settings, then the default

     Modify the tag stack of the window {nr} using {dict}.
     {nr} can be the window number or the |window-ID|.

     For a list of supported items in {dict}, refer to
     |gettagstack()|.  "curidx" takes effect before changing the tag
     stack.
     					*E962*
     How the tag stack is modified depends on the {action}
     argument:
     - If {action} is not present or is set to 'r', then the tag
       stack is replaced.
     - If {action} is set to 'a', then new entries from {dict} are
       pushed (added) onto the tag stack.
     - If {action} is set to 't', then all the entries from the
       current entry in the tag stack or "curidx" in {dict} are
       removed and then new entries are pushed to the stack.

     The current index is set to one after the length of the tag
     stack after the modification.

     Returns zero for success, -1 for failure.

     Examples (for more examples see |tagstack-examples|):
         Empty the tag stack of window 3: >vim
     	call settagstack(3, {'items' : []})

     <    Save and restore the tag stack: >vim

     Escape {string} for use as a shell command argument.

     On Windows when 'shellslash' is not set, encloses {string} in
     double-quotes and doubles all double-quotes within {string}.
     Otherwise encloses {string} in single-quotes and replaces all
     "'" with "'\''".

     The {special} argument adds additional escaping of keywords
     used in Vim commands. If it is a |non-zero-arg|:
     - Special items such as "!", "%", "#" and "<cword>" (as listed
       in |expand()|) will be preceded by a backslash.
       The backslash will be removed again by the |:!| command.
     - The <NL> character is escaped.

     If 'shell' contains "csh" in the tail:
     - The "!" character will be escaped. This is because csh and
       tcsh use "!" for history replacement even in single-quotes.
     - The <NL> character is escaped (twice if {special} is
       a |non-zero-arg|).

     If 'shell' contains "fish" in the tail, the "\" character will
     be escaped because in fish it is used as an escape character
     inside single quotes.

     Example of use with a |:!| command: >vim
         exe '!dir ' .. shellescape(expand('<cfile>'), 1)
     <This results in a directory listing for the file under the
     cursor.  Example of use with |system()|: >vim

     Define a new sign named {name} or modify the attributes of an

     Prefix {name} with a unique text to avoid name collisions.
     There is no {group} like with placing signs.

     The {name} can be a String or a Number.  The optional {dict}
     argument specifies the sign attributes.  The following values
     are supported:
        icon		full path to the bitmap file for the sign.
        linehl	highlight group used for the whole line the
     		sign is placed in.
        priority	default priority value of the sign
        numhl	highlight group used for the line number where
     		the sign is placed.
        text		text that is displayed when there is no icon
     		or the GUI is not being used.
        texthl	highlight group used for the text item
        culhl	highlight group used for the text item when
     		the cursor is on the same line as the sign and
     		'cursorline' is enabled.

     If the sign named {name} already exists, then the attributes
     of the sign are updated.

     The one argument {list} can be used to define a list of signs.
     Each list item is a dictionary with the above items in {dict}
     and a "name" item for the sign name.

     Returns 0 on success and -1 on failure.  When the one argument

     See |sign-group|.

     Each list item in the returned value is a dictionary with the
     following entries:
     	bufnr	number of the buffer with the sign
     	signs	list of signs placed in {bufnr}.  Each list
     		item is a dictionary with the below listed

     The dictionary for each sign contains the following entries:
     	group	 sign group.  Set to '' for the global group.
     	id	 identifier of the sign
     	lnum	 line number where the sign is placed
     	name	 name of the defined sign
     	priority sign priority

     The returned signs in a buffer are ordered by their line
     number and priority.

     Sort the items in {list} in-place.  Returns {list}.

     If you want a list to remain unmodified make a copy first: >vim

     <When {how} is omitted or is a string, then sort() uses the
     string representation of each item to sort on.  Numbers sort
     after Strings, |Lists| after Numbers.  For sorting text in the
     current buffer use |:sort|.

     When {how} is given and it is 'i' then case is ignored.
     For backwards compatibility, the value one can be used to
     ignore case.  Zero means to not ignore case.

     When {how} is given and it is 'l' then the current collation
     locale is used for ordering.  Implementation details:
     strcoll() is used to compare strings.  See |:language| to check
     or set the collation locale.  |v:collate| can also be used to
     check the current locale.  Sorting using the locale typically
     ignores case.  Example: >vim
     	" ö is sorted similarly to o with English locale.
     	language collate en_US.UTF8
     	echo sort(['n', 'o', 'O', 'ö', 'p', 'z'], 'l')
     <	['n', 'o', 'O', 'ö', 'p', 'z'] ~
     >vim
     	" ö is sorted after z with Swedish locale.
     	language collate sv_SE.UTF8
     	echo sort(['n', 'o', 'O', 'ö', 'p', 'z'], 'l')
     <	['n', 'o', 'O', 'p', 'z', 'ö'] ~
     This does not work properly on Mac.

     When {how} is given and it is 'n' then all items will be
     sorted numerical (Implementation detail: this uses the
     strtod() function to parse numbers, Strings, Lists, Dicts and
     Funcrefs will be considered as being 0).

     When {how} is given and it is 'N' then all items will be
     sorted numerical.  This is like 'n' but a string containing
     digits will be used as the number they represent.

     When {how} is given and it is 'f' then all items will be
     sorted numerical.  All values must be a Number or a Float.

     When {how} is a |Funcref| or a function name, this function
     is called to compare items.  The function is invoked with two
     items as argument and must return zero if they are equal, 1 or
     bigger if the first one sorts after the second one, -1 or
     smaller if the first one sorts before the second one.

     {dict} is for functions with the "dict" attribute.  It will be
     used to set the local variable "self". |Dictionary-function|

     The sort is stable, items which compare equal (as number or as
     string) will keep their relative position.  E.g., when sorting
     on numbers, text strings will sort next to each other, in the
     same order as they were originally.


     Example: >vim
     	func MyCompare(i1, i2)
     	   return a:i1 == a:i2 ? 0 : a:i1 > a:i2 ? 1 : -1
     	endfunc

     ignores overflow: >vim
     	func MyCompare(i1, i2)

     {mode} can be "gui" or "cterm", to get the attributes

        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:
     	call			returns ~

     Gets the output of {cmd} as a |string| (|systemlist()| returns

     Result is a String, filtered to avoid platform-specific quirks:
     - <CR><NL> is replaced with <NL>
     - NUL characters are replaced with SOH (0x01)

     Example: >vim
         echo system(['ls', expand('%:h')])

     <If {input} is a string it is written to a pipe and passed as
     stdin to the command.  The string is written as-is, line
     separators are not changed.

     |writefile()| does with {binary} set to "b" (i.e. with
     a newline between each list item, and newlines inside list
     items converted to NULs).
     When {input} is given and is a valid buffer id, the content of
     the buffer is written to the file line by line, each line
     terminated by NL (and NUL where the text has NL).

     Note: system() cannot write to or read from backgrounded ("&")

     If {filename} is passed it is used to prioritize the results

     {filename} should be the full path of the file.

     Each list item is a dictionary with at least the following
     entries:
     	name		Name of the tag.
     	filename	Name of the file where the tag is
     			defined.  It is either relative to the

     			Universal/Exuberant ctags or hdrtag.
     	static		A file specific tag.  Refer to
     			|static-tag| for more information.
     More entries may be present, depending on the content of the
     tags file: access, implementation, inherits and signature.
     Refer to the ctags documentation for information about these
     fields.  For C code the fields "struct", "class" and "enum"
     may appear, they give the name of the entity the tag is
     contained in.

     The ex-command "cmd" can be either an ex search pattern, a
     line number or a line number followed by a byte number.

     If there are no matching tags, then an empty list is returned.

     To get an exact tag match, the anchors '^' and '$' should be
     used in {expr}.  This also make the function work faster.
     Refer to |tag-regexp| for more information about the tag
     search regular expression pattern.

     character index in the String {string} instead of as the byte

     An {idx} in the middle of a UTF-8 sequence is rounded
     downwards to the beginning of that sequence.

     screen cells occupied by the part of the line until the end of
     the character at that position.  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()|.

     For the use of {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.

     When 'virtualedit' is used {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
     'virtualedit'

     If {list} is present and non-zero then virtcol() returns a
     List with the first and last screen position occupied by the
     character.

     With the optional {winid} argument the values are obtained for
     that window instead of the current window.

     Note that only marks in the current file can be used.
     Examples: >vim
     	" With text "foo^Lbar" and cursor on the "^L":

     Temporarily switch to window {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).

     Both {nr} and {target} can be window numbers or |window-ID|s.
     Both must be in the current tab page.

     Returns zero for success, non-zero for failure.

     {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.

     Without {tabnr} use the current tabpage, otherwise the tabpage
     with number {tabnr}.  If the tabpage {tabnr} is not found,

     The result is a Number, which is the number of the current
     window.  The top window has number 1.
     Returns zero for a hidden or non |focusable| window, unless
     it is the current window.

     The optional argument {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

     Returns a sequence of |:resize| commands that should restore

     are opened or closed and the current window and tab page is
     unchanged.

     Uses the |Dictionary| returned by |winsaveview()| to restore
     the view of the current window.
     Note: The {dict} does not have to contain all values, that are
     returned by |winsaveview()|.  If values are missing, those
     settings won't be restored.  So you can use: >vim
         call winrestview({'curswant': 4})
     <
     This will only set the curswant value (the column the cursor
     wants to move on vertical movements) of the cursor to column 5
     (yes, that is 5), while all other settings will remain the
     same.  This is useful, if you set the cursor position
     manually.

     If you have changed the values the result is unpredictable.
     If the window size changed the result won't be the same.

 winsaveview = {
   desc = [=[
     Returns a |Dictionary| that contains information to restore
     the view of the current window.  Use |winrestview()| to
     restore the view.
     This is useful if you have a mapping that jumps around in the
     buffer and you want to go back to the original view.
     This does not save fold information.  Use the 'foldenable'
     option to temporarily switch off folding, so that folds are
     not opened when moving around.  This may have side effects.
     The return value includes:
     	lnum		cursor line number
     	col		cursor column (Note: the first column
     			zero, as opposed to what |getcurpos()|
     			returns)
     	coladd		cursor column offset for 'virtualedit'
     	curswant	column for vertical movement (Note:
     			the first column is zero, as opposed
     			to what |getcurpos()| returns).  After
     			|$| command it will be a very large
     			number equal to |v:maxcol|.
     	topline		first line in the window
     	topfill		filler lines, only in diff mode
     	leftcol		first column displayed; only used when
     			'wrap' is off
     	skipcol		columns skipped

 writefile = {

   base = 1,
   desc = [=[
     When {object} is a |List| write it to file {fname}.  Each list
     item is separated with a NL.  Each list item must be a String
     or Number.
     All NL characters are replaced with a NUL character.
     Inserting CR characters needs to be done before passing {list}
     to writefile().

     When {object} is a |Blob| write the bytes to file {fname}
     unmodified, also when binary mode is not specified.

     {flags} must be a String.  These characters are recognized:

     'b'  Binary mode is used: There will not be a NL after the
          last list item.  An empty item at the end does cause the
          last line in the file to end in a NL.

     'a'  Append mode is used, lines are appended to the file: >vim
     	call writefile(["foo"], "event.log", "a")
     	call writefile(["bar"], "event.log", "a")
     <
     'D'  Delete the file when the current function ends.  This
          works like: >vim
     	defer delete({fname})
     <     Fails when not in a function.  Also see |:defer|.

     's'  fsync() is called after writing the file.  This flushes
          the file to disk, if possible.  This takes more time but
          avoids losing the file if the system crashes.

     'S'  fsync() is not called, even when 'fsync' is set.

          When {flags} does not contain "S" or "s" then fsync() is
          called if the 'fsync' option is set.

     An existing file is overwritten, if possible.

     When the write fails -1 is returned, otherwise 0.  There is an
     error message if the file can't be created or when writing
     fails.

     Also see |readfile()|.
