INTRODUCTION                                                       *lua-intro*

The Lua 5.1 script engine is builtin and always available. Try this command to
get an idea of what lurks beneath: >vim

   :lua vim.print(package.loaded)

Nvim includes a "standard library" |lua-stdlib| for Lua.  It complements the
"editor stdlib" (|vimscript-functions| + |Ex-commands|) and the |API|, all of
which can be used from Lua code (|lua-vimscript| |vim.api|). These three
namespaces form the Nvim programming interface.

Lua plugins and user config are automatically discovered and loaded, just like
Vimscript. See |lua-guide| for practical guidance.

You can also run Lua scripts from your shell using the |-l| argument: >
   nvim -l foo.lua [args...]
<
                                                                 *lua-compat*
Lua 5.1 is the permanent interface for Nvim Lua. Plugins should target Lua 5.1
as specified in |luaref|; later versions (which are essentially different,
incompatible, dialects) are not supported. This includes extensions such as
`goto` that some Lua 5.1 interpreters like LuaJIT may support.

                                                                 *lua-luajit*
While Nvim officially only requires Lua 5.1 support, it should be built with
LuaJIT or a compatible fork on supported platforms for performance reasons.
LuaJIT also comes with useful extensions such as `ffi`, |lua-profile|, and
enhanced standard library functions; these cannot be assumed to be available,
and Lua code in |init.lua| or plugins should check the `jit` global variable
before using them: >lua
 if jit then
   -- code for luajit
 else
   -- code for plain lua 5.1
 end
<
One exception is the LuaJIT `bit` extension, which is always available: when
built with PUC Lua, Nvim includes a fallback implementation which provides
`require("bit")`. See |lua-bit|.

                                                                 *lua-profile*
If Nvim is built with LuaJIT, Lua code can be profiled via >lua
   -- Start a profiling session:
   require('jit.p').start('ri1', '/tmp/profile')

   -- Perform arbitrary tasks (use plugins, scripts, etc.) ...

   -- Stop the session. Profile is written to /tmp/profile.
   require('jit.p').stop()

See https://luajit.org/ext_profiler.html or the `p.lua` source for details: >
   :lua vim.cmd.edit(package.searchpath('jit.p', package.path))

==============================================================================
LUA CONCEPTS AND IDIOMS                                         *lua-concepts*

Lua is very simple, and _consistent_: while there are some quirks, once you
internalize those quirks, everything works the same everywhere. Scopes
(closures) in particular are very consistent, unlike JavaScript or most other
languages.

Lua has three fundamental mechanisms—one for "each major aspect of
programming": tables, closures, and coroutines.
https://www.lua.org/doc/cacm2018.pdf
- Tables are the "object" or container datastructure: they represent both
 lists and maps, you can extend them to represent your own datatypes and
 change their behavior using |metatable|s (like Python's "datamodel").
- EVERY scope in Lua is a closure: a function is a closure, a module is
 a closure, a `do` block (|lua-do|) is a closure--and they all work the same.
 A Lua module is literally just a big closure discovered on the "path"
 (where your modules are found: |package.cpath|).
- Stackful coroutines enable cooperative multithreading, generators, and
 versatile control for both Lua and its host (Nvim).

                                                         *lua-error-handling*
Lua functions may throw |lua-errors| for exceptional (unexpected) failures,
which you can handle with |pcall()|.
                                                      *lua-result-or-message*
When failure is normal and expected, it's idiomatic to return `nil` which
signals to the caller that failure is not "exceptional" and must be handled.
This "result-or-message" pattern is expressed as the multi-value return type
`any|nil,nil|string`, or in LuaLS notation: >

   ---@return any|nil    # result on success, nil on failure.
   ---@return nil|string # nil on success, error message on failure.
<
Examples of the "result-or-message" pattern:
- |vim.ui.open()|
- |io.open()|
- |luv-error-handling|

When a caller can't proceed on failure, it's idiomatic to `assert()` the
"result-or-message" result: >lua

   local value = assert(fn())

Guidance: use the "result-or-message" pattern for...
- Functions where failure is expected, especially when communicating with the
 external world. E.g. HTTP requests or LSP requests often fail because of
 server problems, even if the caller did everything right.
- Functions that return a value, e.g. Foo:new().
- When there is a list of known error codes which can be returned as a third
 value (like |luv-error-handling|).
<
                                                                   *iterator*
An iterator is just a function that can be called repeatedly to get the "next"
value of a collection (or any other |iterable|). This interface is expected by
|for-in| loops, produced by |pairs()|, supported by |vim.iter|, etc.
https://www.lua.org/pil/7.1.html

                                                                   *iterable*
An "iterable" is anything that |vim.iter()| can consume: tables, dicts, lists,
iterator functions, tables implementing the |__call()| metamethod, and
|vim.iter()| objects.

                                                              *list-iterator*
Iterators on |lua-list| tables have a "middle" and "end", whereas iterators in
general may be logically infinite. Therefore some |vim.iter| operations (e.g.
|Iter:rev()|) make sense only on list-like tables (which are finite by
definition).

                                                          *lua-function-call*
Lua functions can be called in multiple ways. Consider the function: >lua
   local foo = function(a, b)
       print("A: ", a)
       print("B: ", b)
   end

The first way to call this function is: >lua
   foo(1, 2)
   -- ==== Result ====
   -- A: 1
   -- B: 2

This way of calling a function is familiar from most scripting languages. In
Lua, any missing arguments are passed as `nil`, and extra parameters are
silently discarded. Example: >lua
   foo(1)
   -- ==== Result ====
   -- A: 1
   -- B: nil
<
                                                                     *kwargs*
When calling a function, you can omit the parentheses if the function takes
exactly one string literal (`"foo"`) or table literal (`{1,2,3}`). The latter
is often used to mimic "named parameters" ("kwargs" or "keyword args") as in
languages like Python and C#. Example: >lua
   local func_with_opts = function(opts)
       local will_do_foo = opts.foo
       local filename = opts.filename
       -- ...
   end

   func_with_opts { foo = true, filename = "hello.world" }
<
There's nothing special going on here except that parentheses are implicitly
added. But visually, this small bit of sugar gets reasonably close to a
"keyword args" interface.

                                                                  *lua-regex*
Lua intentionally does not support regular expressions, instead it has limited
|lua-pattern|s which avoid the performance pitfalls of extended regex. Lua
scripts can also use Vim regex via |vim.regex()|.

Examples: >lua

   print(string.match("foo123bar123", "%d+"))
   -- 123
   print(string.match("foo123bar123", "[^%d]+"))
   -- foo
   print(string.match("foo123bar123", "[abc]+"))
   -- ba
   print(string.match("foo.bar", "%.bar"))
   -- .bar
<
                                                                 *lua-truthy*
Only `false` and `nil` evaluate to "false" in Lua. All other values are "true".


==============================================================================
IMPORTING LUA MODULES                                        *lua-module-load*

Modules are searched for under the directories specified in 'runtimepath' and
|packages-runtimepath|, in the order they appear in the output of this command
>vim
   :echo nvim_list_runtime_paths()
<
Any "." in the module name is treated as a directory separator when searching.
For a module `foo.bar`, each directory is searched for `lua/foo/bar.lua`, then
`lua/foo/bar/init.lua`.  If no files are found, the directories are searched
again for a shared library with a name matching `lua/foo/bar.?`, where `?` is
a list of suffixes (such as `so` or `dll`) derived from the initial value of
|package.cpath|. If still no files are found, Nvim falls back to Lua's default
search mechanism. The first script found is run and `require()` returns the
value returned by the script if any, else `true`.

The return value is cached after the first call to `require()` for each module,
with subsequent calls returning the cached value without searching for, or
executing any script. For further details see |require()|.

For example, if 'runtimepath' is `foo,bar` and |package.cpath| was
`./?.so;./?.dll` at startup, `require('mod')` searches these paths in order
and loads the first module found ("first wins"): >
   foo/lua/mod.lua
   foo/lua/mod/init.lua
   bar/lua/mod.lua
   bar/lua/mod/init.lua
   foo/lua/mod.so
   foo/lua/mod.dll
   bar/lua/mod.so
   bar/lua/mod.dll
<
Note:

- Although 'runtimepath' is tracked, Nvim does not track current
 values of |package.path| or |package.cpath|. If you happen to delete some
 paths from there you can set 'runtimepath' to trigger an update: >vim
     let &runtimepath = &runtimepath

- Skipping paths from 'runtimepath' which contain semicolons applies both to
 |package.path| and |package.cpath|. Given that there are some badly written
 plugins using shell, which will not work with paths containing semicolons,
 it is better to not have them in 'runtimepath' at all.

                                                        *lua-script-location*
To get its own location, Lua scripts/modules can use |debug.getinfo()|: >
   debug.getinfo(1, 'S').source:gsub('^@', '')
<

==============================================================================
COMMANDS                                                        *lua-commands*

These commands execute a Lua chunk from either the command line (:lua, :luado)
or a file (:luafile) on the given line [range]. As always in Lua, each chunk
has its own scope (closure), so only global variables are shared between
command calls. The |lua-stdlib| modules, user modules, and anything else on
|package.path| are available.

The Lua print() function redirects its output to the Nvim message area, with
arguments separated by " " (space) instead of "\t" (tab).

                                                                 *:lua=* *:lua*
:lua {chunk}
   Executes Lua chunk {chunk}. If {chunk} starts with "=" the rest of the
   chunk is evaluated as an expression and printed. `:lua =expr` and `:=expr`
   are equivalent to `:lua print(vim.inspect(expr))`. |E5107| |E5108|

   Examples: >vim
       :lua vim.api.nvim_command('echo "Hello, Nvim!"')
<    To see the Lua version: >vim
       :lua print(_VERSION)
<    To see the LuaJIT version: >vim
       :lua =jit.version
<
:{range}lua
   Executes buffer lines in {range} as Lua code. Unlike |:source|, this
   always treats the lines as Lua code.

   Example: select the following code and type ":lua<Enter>" to execute it: >lua
       print(string.format(
           'unix time: %s', os.time()))
<
                                                               *:lua-heredoc*
:lua << [trim] [{endmarker}]
{script}
{endmarker}
   Executes Lua script {script} from within Vimscript. You can omit
   [endmarker] after the "<<" and use a dot "." after {script} (similar to
   |:append|, |:insert|). Refer to |:let-heredoc| for more information.

   Example: >vim
       function! CurrentLineInfo()
       lua << EOF
       local linenr = vim.api.nvim_win_get_cursor(0)[1]
       local curline = vim.api.nvim_buf_get_lines(0, linenr - 1, linenr, false)[1]
       print(string.format('Line [%d] has %d bytes', linenr, #curline))
       EOF
       endfunction
<
   Note that the `local` variables will disappear when the block finishes.
   But not globals.

                                                                     *:luado*
:[range]luado {body}
   Executes Lua chunk "function(line, linenr) {body} end" for each buffer
   line in [range], where `line` is the current line text (without <EOL>),
   and `linenr` is the current line number. If the function returns a string
   that becomes the text of the corresponding buffer line. Default [range] is
   the whole file: "1,$". |E5109| |E5110| |E5111|

   Examples: >vim
       :luado return string.format("%s\t%d", line:reverse(), #line)

       :lua require"lpeg"
       :lua -- balanced parenthesis grammar:
       :lua bp = lpeg.P{ "(" * ((1 - lpeg.S"()") + lpeg.V(1))^0 * ")" }
       :luado if bp:match(line) then return "=>\t" .. line end
<
                                                                   *:luafile*
:luafile {file}
   Execute Lua script in {file}.
   The whole argument is used as the filename (like |:edit|), spaces do not
   need to be escaped. Alternatively you can |:source| Lua files.
   |E5111| |E5112| |E5113|

   Examples: >vim
       :luafile script.lua
       :luafile %
<

==============================================================================
luaeval()                                                 *lua-eval*

The (dual) equivalent of "vim.eval" for passing Lua values to Nvim is
"luaeval". "luaeval" takes an expression string and an optional argument used
for _A inside expression and returns the result of the expression. It is
semantically equivalent in Lua to: >lua

   local chunkheader = "local _A = select(1, ...) return "
   function luaeval (expstr, arg)
       local chunk = assert(loadstring(chunkheader .. expstr, "luaeval"))
       return chunk(arg) -- return typval
   end
<
Lua nils, numbers, strings, tables and booleans are converted to their
respective Vimscript types. If a Lua string contains a NUL byte, it will be
converted to a |Blob|. Conversion of other Lua types is an error.

The magic global "_A" contains the second argument to luaeval().

Example: >vim
   :echo luaeval('_A[1] + _A[2]', [40, 2])
   " 42
   :echo luaeval('string.match(_A, "[a-z]+")', 'XYXfoo123')
   " foo
<
                                                        *lua-table-ambiguous*
Lua tables are used as both dictionaries and lists, so it is impossible to
decide whether empty table is a list or a dict. Also Lua does not have integer
numbers. To disambiguate these cases, we define:
                                                                   *lua-list*
0. Empty table is a list. Use |vim.empty_dict()| to represent empty dict.
1. Table with N consecutive (no `nil` values, aka "holes") integer keys 1…N is
  a list. See also |list-iterator|.
                                                                   *lua-dict*
2. Table with string keys, none of which contains NUL byte, is a dict.
3. Table with string keys, at least one of which contains NUL byte, is also
  considered to be a dictionary, but this time it is converted to
  a |msgpack-special-map|.
                                                            *lua-special-tbl*
4. Table with `vim.type_idx` key may be a dictionary, a list or floating-point
  value:
  - `{[vim.type_idx]=vim.types.float, [vim.val_idx]=1}` is converted to
    a floating-point 1.0. Note that by default integral Lua numbers are
    converted to |Number|s, non-integral are converted to |Float|s. This
    variant allows integral |Float|s.
  - `{[vim.type_idx]=vim.types.dictionary}` is converted to an empty
    dictionary, `{[vim.type_idx]=vim.types.dictionary, [42]=1, a=2}` is
    converted to a dictionary `{'a': 42}`: non-string keys are ignored.
    Without `vim.type_idx` key tables with keys not fitting in 1., 2. or 3.
    are errors.
  - `{[vim.type_idx]=vim.types.array}` is converted to an empty list. As well
    as `{[vim.type_idx]=vim.types.array, [42]=1}`: integral keys that do not
    form a 1-step sequence from 1 to N are ignored, as well as all
    non-integral keys.

Examples: >vim

   :echo luaeval('math.pi')
   :function Rand(x,y) " random uniform between x and y
   :  return luaeval('(_A.y-_A.x)*math.random()+_A.x', {'x':a:x,'y':a:y})
   :  endfunction
   :echo Rand(1,10)
<
Note: Second argument to `luaeval` is converted ("marshalled") from Vimscript
to Lua, so changes to Lua containers do not affect values in Vimscript. Return
value is also always converted. When converting, |msgpack-special-dict|s are
treated specially.

==============================================================================
Vimscript v:lua interface                                         *v:lua-call*

From Vimscript the special `v:lua` prefix can be used to call Lua functions
which are global or accessible from global tables. The expression >vim
   call v:lua.func(arg1, arg2)
is equivalent to the Lua chunk >lua
   return func(...)
where the args are converted to Lua values. The expression >vim
   call v:lua.somemod.func(args)
is equivalent to the Lua chunk >lua
   return somemod.func(...)

Lua module functions can be accessed like: >vim
   call v:lua.require'mypack'.func(arg1, arg2)
   call v:lua.require'mypack.submod'.func(arg1, arg2)
Note: Only single quote form without parens is allowed. Using
`require"mypack"` or `require('mypack')` as a prefix does NOT work.

You can use `v:lua` in "func" options like 'tagfunc', 'omnifunc', etc.
For example consider the following Lua omnifunc handler: >lua

   function mymod.omnifunc(findstart, base)
     if findstart == 1 then
       return 0
     else
       return {'stuff', 'steam', 'strange things'}
     end
   end
   -- Note: The module ("mymod") must be a Lua global, or use require() as
   -- shown above to access it from a package.
   vim.bo[buf].omnifunc = 'v:lua.mymod.omnifunc'

You can also use `v:lua` to call Lua functions as Vimscript |method|s: >vim
   :eval arg1->v:lua.somemod.func(arg2)
<
Note: `v:lua` without a call is not allowed in a Vimscript expression:
|Funcref|s cannot represent Lua functions. The following are errors: >vim

   let g:Myvar = v:lua.myfunc        " Error
   call SomeFunc(v:lua.mycallback)   " Error
   let g:foo = v:lua                 " Error
   let g:foo = v:['lua']             " Error
<
==============================================================================
Lua standard modules                                              *lua-stdlib*

The Nvim Lua "standard library" (stdlib) is the `vim` module, which exposes
various functions and sub-modules. It is always loaded, thus `require("vim")`
is unnecessary.

You can peek at the module properties: >vim

   :lua vim.print(vim)

Result is something like this: >

   {
     _os_proc_children = <function 1>,
     _os_proc_info = <function 2>,
     ...
     api = {
       nvim__id = <function 5>,
       nvim__id_array = <function 6>,
       ...
     },
     deepcopy = <function 106>,
     gsplit = <function 107>,
     ...
   }

To find documentation on e.g. the "deepcopy" function: >vim

   :help vim.deepcopy()

Note that underscore-prefixed functions (e.g. "_os_proc_children") are
internal/private and must not be used by plugins.

------------------------------------------------------------------------------
VIM.UV                                                   *lua-loop* *vim.uv*

`vim.uv` exposes the "luv" Lua bindings for the libUV library that Nvim uses
for networking, filesystem, and process management, see |luvref.txt|.
In particular, it allows interacting with the main Nvim |luv-event-loop|.

                                                   *E5560* *lua-loop-callbacks*
It is an error to directly invoke `vim.api` functions (except |api-fast|) in
`vim.uv` callbacks. For example, this is an error: >lua

   local timer = vim.uv.new_timer()
   timer:start(1000, 0, function()
     vim.api.nvim_command('echomsg "test"')
   end)
<
To avoid the error use |vim.schedule_wrap()| to defer the callback: >lua

   local timer = vim.uv.new_timer()
   timer:start(1000, 0, vim.schedule_wrap(function()
     vim.api.nvim_command('echomsg "test"')
   end))
<
(For one-shot timers, see |vim.defer_fn()|, which automatically adds the
wrapping.)

Example: repeating timer
   1. Save this code to a file.
   2. Execute it with ":luafile %". >lua

   -- Create a timer handle (implementation detail: uv_timer_t).

Example: File-change detection                                    *watch-file*
   1. Save this code to a file.
   2. Execute it with ":luafile %".
   3. Use ":Watch %" to watch any file.
   4. Try editing the file from another text editor.
   5. Observe that the file reloads in Nvim (because on_change() calls
      |:checktime|). >lua

   local w = vim.uv.new_fs_event()
   local function on_change(err, fname, status)
     -- Do work...
     vim.api.nvim_command('checktime')
     -- Debounce: stop/start.
     w:stop()
     watch_file(fname)
   end
   function watch_file(fname)
     local fullpath = vim.api.nvim_call_function(
       'fnamemodify', {fname, ':p'})
     w:start(fullpath, {}, vim.schedule_wrap(function(...)
       on_change(...) end))
   end
   vim.api.nvim_command(
     "command! -nargs=1 Watch call luaeval('watch_file(_A)', expand('<args>'))")

                                                        *inotify-limitations*
When on Linux you may need to increase the maximum number of `inotify` watches
and queued events as the default limit can be too low. To increase the limit,
run: >bash
   sysctl fs.inotify.max_user_watches=494462
<
This will increase the limit to 494462 watches and queued events. These lines
can be added to `/etc/sysctl.conf` to make the changes persistent.

Note that each watch is a structure in the Kernel, thus available memory is
also a bottleneck for using inotify. In fact, a watch can take up to 1KB of
space. This means a million watches could result in 1GB of extra RAM usage.

Example: TCP echo-server                                          *tcp-server*
   1. Save this code to a file.
   2. Execute it with ":luafile %".
   3. Note the port number.
   4. Connect from any TCP client (e.g. "nc 0.0.0.0 36795"): >lua

   local function create_server(host, port, on_connect)
     local server = vim.uv.new_tcp()
     server:bind(host, port)
     server:listen(128, function(err)
       assert(not err, err)  -- Check for errors.
       local sock = vim.uv.new_tcp()
       server:accept(sock)  -- Accept client connection.
       on_connect(sock)  -- Start reading messages.
     end)
     return server
   end
   local server = create_server('0.0.0.0', 0, function(sock)
     sock:read_start(function(err, chunk)
       assert(not err, err)  -- Check for errors.
       if chunk then
         sock:write(chunk)  -- Echo received messages to the channel.
       else  -- EOF (stream closed).
         sock:close()  -- Always close handles to avoid leaks.
       end
     end)
   end)
   print('TCP echo-server listening on port: '..server:getsockname().port)

Multithreading                                            *lua-loop-threading*

Plugins can perform work in separate (os-level) threads using the threading
APIs in luv, for instance `vim.uv.new_thread`. Each thread has its own
separate Lua interpreter state, with no access to Lua globals on the main
thread. Neither can the editor state (buffers, windows, etc) be directly
accessed from threads.

A subset of the `vim.*` stdlib is available in threads, including:

- `vim.uv` with a separate event loop per thread.
- `vim.mpack` and `vim.json` (useful for serializing messages between threads)
- `require` in threads can use Lua packages from the global |package.path|
- `print()` and `vim.inspect`
- `vim.text.diff`
- Most utility functions in `vim.*` that work with pure Lua values, like
 `vim.split`, `vim.tbl_*`, `vim.list_*`, etc.
- `vim.is_thread()` returns true from a non-main thread.

VIM                                                              *vim.builtin*


vim.api.{func}({...})                                                *vim.api*
   Invokes Nvim |API| function {func} with arguments {...}.
   Example: call the "nvim_get_current_line()" API function: >lua
       print(tostring(vim.api.nvim_get_current_line()))

vim.NIL                                                              *vim.NIL*
   Special value representing NIL in |RPC| and |v:null| in Vimscript
   conversion, and similar cases. Lua `nil` cannot be used as part of a Lua
   table representing a Dictionary or Array, because it is treated as
   missing: `{"foo", nil}` is the same as `{"foo"}`.

vim.type_idx                                                    *vim.type_idx*
   Type index for use in |lua-special-tbl|. Specifying one of the values from
   |vim.types| allows typing the empty table (it is unclear whether empty Lua
   table represents empty list or empty array) and forcing integral numbers
   to be |Float|. See |lua-special-tbl| for more details.

vim.val_idx                                                      *vim.val_idx*
   Value index for tables representing |Float|s. A table representing
   floating-point value 1.0 looks like this: >lua
       {
         [vim.type_idx] = vim.types.float,
         [vim.val_idx] = 1.0,
       }
<    See also |vim.type_idx| and |lua-special-tbl|.

vim.types                                                          *vim.types*
   Table with possible values for |vim.type_idx|. Contains two sets of
   key-value pairs: first maps possible values for |vim.type_idx| to
   human-readable strings, second maps human-readable type names to values
   for |vim.type_idx|. Currently contains pairs for `float`, `array` and
       `dictionary` types.

   Note: One must expect that values corresponding to `vim.types.float`,
   `vim.types.array` and `vim.types.dictionary` fall under only two following
   assumptions:
   1. Value may serve both as a key and as a value in a table. Given the
      properties of Lua tables this basically means “value is not `nil`”.
   2. For each value in `vim.types` table `vim.types[vim.types[value]]` is the
      same as `value`.
   No other restrictions are put on types, and it is not guaranteed that
   values corresponding to `vim.types.float`, `vim.types.array` and
   `vim.types.dictionary` will not change or that `vim.types` table will only
   contain values for these three types.

                                                  *log_levels* *vim.log.levels*
Log levels are one of the values defined in `vim.log.levels`:

   vim.log.levels.DEBUG
   vim.log.levels.ERROR
   vim.log.levels.INFO
   vim.log.levels.TRACE
   vim.log.levels.WARN
   vim.log.levels.OFF



vim.empty_dict()                                            *vim.empty_dict()*
   Creates a special empty table (marked with a metatable), which Nvim
   converts to an empty dictionary when translating Lua values to Vimscript
   or API types. Nvim by default converts an empty table `{}` without this
   metatable to an list/array.

   Note: If numeric keys are present in the table, Nvim ignores the metatable
   marker and converts the dict to a list/array anyway.

   Return: ~
       (`table`)

vim.iconv({str}, {from}, {to})                                   *vim.iconv()*
   The result is a String, which is the text {str} converted from encoding
   {from} to encoding {to}. When the conversion fails `nil` is returned. When
   some characters could not be converted they are replaced with "?". The
   encoding names are whatever the iconv() library function can accept, see
   ":Man 3 iconv".

   Parameters: ~
     • {str}   (`string`) Text to convert
     • {from}  (`string`) Encoding of {str}
     • {to}    (`string`) Target encoding

   Return: ~
       (`string?`) Converted string if conversion succeeds, `nil` otherwise.

vim.in_fast_event()                                      *vim.in_fast_event()*
   Returns true if the code is executing as part of a "fast" event handler,
   where most of the API is disabled. These are low-level events (e.g.
   |lua-loop-callbacks|) which can be invoked whenever Nvim polls for input.
   When this is `false` most API functions are callable (but may be subject
   to other restrictions such as |textlock|).

vim.rpcnotify({channel}, {method}, {...})                    *vim.rpcnotify()*
   Sends {event} to {channel} via |RPC| and returns immediately. If {channel}
   is 0, the event is broadcast to all channels.

   This function also works in a fast callback |lua-loop-callbacks|.

   Parameters: ~
     • {channel}  (`integer`)
     • {method}   (`string`)
     • {...}      (`any?`)

vim.rpcrequest({channel}, {method}, {...})                  *vim.rpcrequest()*
   Invokes |RPC| `method` on `channel` and blocks until a response is
   received.

   Note: Msgpack NIL values in the response are represented as |vim.NIL|.

   Example: see |nvim_exec_lua()|

   Parameters: ~
     • {channel}  (`integer`)
     • {method}   (`string`)
     • {...}      (`any?`)

vim.schedule({fn})                                            *vim.schedule()*
   Schedules {fn} to be invoked soon by the main event-loop. Useful to avoid
   |textlock| or other temporary restrictions.

   Parameters: ~
     • {fn}  (`fun()`)

   Return (multiple): ~
       (`nil`) result
       (`string?`) err Error message if scheduling failed, `nil` otherwise.

vim.str_utf_end({str}, {index})                            *vim.str_utf_end()*
   Gets the distance (in bytes) from the last byte of the codepoint
   (character) that {index} points to.

   Examples: >lua
       -- The character 'æ' is stored as the bytes '\xc3\xa6' (using UTF-8)

       -- Returns 0 because the index is pointing at the last byte of a character
       vim.str_utf_end('æ', 2)

       -- Returns 1 because the index is pointing at the penultimate byte of a character
       vim.str_utf_end('æ', 1)
<

   Parameters: ~
     • {str}    (`string`)
     • {index}  (`integer`)

   Return: ~
       (`integer`)

vim.str_utf_pos({str})                                     *vim.str_utf_pos()*
   Gets a list of the starting byte positions of each UTF-8 codepoint in the
   given string.

   Embedded NUL bytes are treated as terminating the string.

   Parameters: ~
     • {str}  (`string`)

   Return: ~
       (`integer[]`)

vim.str_utf_start({str}, {index})                        *vim.str_utf_start()*
   Gets the distance (in bytes) from the starting byte of the codepoint
   (character) that {index} points to.

   The result can be added to {index} to get the starting byte of a
   character.

   Examples: >lua
       -- The character 'æ' is stored as the bytes '\xc3\xa6' (using UTF-8)

       -- Returns 0 because the index is pointing at the first byte of a character
       vim.str_utf_start('æ', 1)

       -- Returns -1 because the index is pointing at the second byte of a character
       vim.str_utf_start('æ', 2)
<

   Parameters: ~
     • {str}    (`string`)
     • {index}  (`integer`)

   Return: ~
       (`integer`)

vim.stricmp({a}, {b})                                          *vim.stricmp()*
   Compares strings case-insensitively.

   Parameters: ~
     • {a}  (`string`)
     • {b}  (`string`)

   Return: ~
       (`0|1|-1`) if strings are equal, {a} is greater than {b} or {a} is
       lesser than {b}, respectively.

vim.ui_attach({ns}, {opts}, {callback})                      *vim.ui_attach()*
   WARNING: This feature is experimental/unstable.

   Subscribe to |ui-events|, similar to |nvim_ui_attach()| but receive events
   in a Lua callback. Used to implement screen elements like popupmenu or
   message handling in Lua.

   {callback} receives event name plus additional parameters. See
   |ui-popupmenu| and the sections below for event format for respective
   events.

   Callbacks for `msg_show` events originating from internal messages (as
   opposed to events from commands or API calls) are executed in |api-fast|
   context; showing the message needs to be scheduled.

   Excessive errors inside the callback will result in forced detachment.

   WARNING: This api is considered experimental. Usability will vary for
   different screen elements. In particular `ext_messages` behavior is
   subject to further changes and usability improvements. This is expected to
   be used to handle messages when setting 'cmdheight' to zero (which is
   likewise experimental).

   Example (stub for a |ui-popupmenu| implementation): >lua
       ns = vim.api.nvim_create_namespace('my_fancy_pum')

       vim.ui_attach(ns, {ext_popupmenu=true}, function(event, ...)
         if event == 'popupmenu_show' then
           local items, selected, row, col, grid = ...
           print('display pum ', #items)
         elseif event == 'popupmenu_select' then
           local selected = ...
           print('selected', selected)
         elseif event == 'popupmenu_hide' then
           print('FIN')
         end
       end)
<

   Parameters: ~
     • {ns}        (`integer`) Namespace ID
     • {opts}      (`table<string, any>`) Optional parameters.
                   • {ext_…}? (`boolean`) Any of |ui-ext-options|, if true
                     enable events for the respective UI element.
                   • {set_cmdheight}? (`boolean`) If false, avoid setting
                     'cmdheight' to 0 when `ext_messages` is enabled.
     • {callback}  (`fun(event: string, ...): any`) Function called for each
                   UI event. A truthy return value signals to Nvim that the
                   event is handled, in which case it is not propagated to
                   remote UIs.

vim.ui_detach({ns})                                          *vim.ui_detach()*
   Detach a callback previously attached with |vim.ui_attach()| for the given
   namespace {ns}.

   Parameters: ~
     • {ns}  (`integer`) Namespace ID

vim.wait({time}, {callback}, {interval}, {fast_only})             *vim.wait()*
   Waits up to `time` milliseconds, until `callback` returns `true`
   (success). Executes `callback` immediately, then on user events, internal
   events, and approximately every `interval` milliseconds (default 200).
   Returns all `callback` results on success.

   Nvim processes other events while waiting. Cannot be called during an
   |api-fast| event.

   Examples: >lua
       -- Wait for 100 ms, allowing other events to process.
       vim.wait(100)

       -- Wait up to 1000 ms or until `vim.g.foo` is true, at intervals of ~500 ms.
       vim.wait(1000, function() return vim.g.foo end, 500)

       -- Wait indefinitely until `vim.g.foo` is true, and get the callback results.
       local ok, rv1, rv2, rv3 = vim.wait(math.huge, function()
         return vim.g.foo, 'a', 42, { ok = { 'yes' } }
       end)

       -- Schedule a function to set a value in 100ms. This would wait 10s if blocked, but actually
       -- only waits 100ms because `vim.wait` processes other events while waiting.
       vim.defer_fn(function() vim.g.timer_result = true end, 100)
       if vim.wait(10000, function() return vim.g.timer_result end) then
         print('Only waiting a little bit of time!')
       end
<

   Parameters: ~
     • {time}       (`number`) Number of milliseconds to wait. Must be
                    non-negative number, any fractional part is truncated.
     • {callback}   (`fun(): boolean, ...?`) Optional callback. Waits until
                    {callback} returns true
     • {interval}   (`integer?`) (Approximate) number of milliseconds to wait
                    between polls
     • {fast_only}  (`boolean?`) If true, only |api-fast| events will be
                    processed.

   Return (multiple): ~
       (`boolean`)
       (`-1|-2?`)
       • If callback returns `true` before timeout: `true, nil, ...`
       • On timeout: `false, -1`
       • On interrupt: `false, -2`
       • On error: the error is raised.


==============================================================================
LUA-VIMSCRIPT BRIDGE                                           *lua-vimscript*

Nvim Lua provides an interface or "bridge" to Vimscript variables and
functions, and editor commands and options.

Objects passed over this bridge are COPIED (marshalled): there are no
"references". |lua-guide-variables| For example, using `vim.fn.remove()` on a
Lua list copies the list object to Vimscript and does NOT modify the Lua list: >lua
   local list = { 1, 2, 3 }
   vim.fn.remove(list, 0)
   vim.print(list)  --> "{ 1, 2, 3 }"
<


vim.call({func}, {...})                                           *vim.call()*
   Invokes |vim-function| or |user-function| {func} with arguments {...}.
   See also |vim.fn|.
   Equivalent to: >lua
       vim.fn[func]({...})
<
vim.cmd({command})
   See |vim.cmd()|.

vim.fn.{func}({...})                                                  *vim.fn*
   Invokes |vim-function| or |user-function| {func} with arguments {...}.
   To call autoload functions, use the syntax: >lua
       vim.fn['some#function']({...})
<
   Unlike vim.api.|nvim_call_function()| this converts directly between Vim
   objects and Lua objects. If the Vim function returns a float, it will be
   represented directly as a Lua number. Empty lists and dictionaries both
   are represented by an empty table.

   Note: |v:null| values as part of the return value is represented as
   |vim.NIL| special value

   Note: vim.fn keys are generated lazily, thus `pairs(vim.fn)` only
   enumerates functions that were called at least once.

   Note: The majority of functions cannot run in |api-fast| callbacks with some
   undocumented exceptions which are allowed.

                                                          *lua-vim-variables*
The Vim editor global dictionaries |g:| |w:| |b:| |t:| |v:| can be accessed
from Lua conveniently and idiomatically by referencing the `vim.*` Lua tables
described below. In this way you can easily read and modify global Vimscript
variables from Lua.

Example: >lua

   vim.g.foo = 5     -- Set the g:foo Vimscript variable.
   print(vim.g.foo)  -- Get and print the g:foo Vimscript variable.
   vim.g.foo = nil   -- Delete (:unlet) the Vimscript variable.
   vim.b[2].foo = 6  -- Set b:foo for buffer 2
<

Note that setting dictionary fields directly will not write them back into
Nvim. This is because the index into the namespace simply returns a copy.
Instead the whole dictionary must be written as one. This can be achieved by
creating a short-lived temporary.

Example: >lua

   vim.g.my_dict.field1 = 'value'  -- Does not work

   local my_dict = vim.g.my_dict   --
   my_dict.field1 = 'value'        -- Instead do
   vim.g.my_dict = my_dict         --

vim.g                                                                  *vim.g*
   Global (|g:|) editor variables.
   Key with no value returns `nil`.

vim.b                                                                  *vim.b*
   Buffer-scoped (|b:|) variables for the current buffer.
   Invalid or unset key returns `nil`. Can be indexed with
   an integer to access variables for a specific buffer.

vim.w                                                                  *vim.w*
   Window-scoped (|w:|) variables for the current window.
   Invalid or unset key returns `nil`. Can be indexed with
   an integer to access variables for a specific window.

vim.t                                                                  *vim.t*
   Tabpage-scoped (|t:|) variables for the current tabpage.
   Invalid or unset key returns `nil`. Can be indexed with
   an integer to access variables for a specific tabpage.

vim.v                                                                  *vim.v*
   |v:| variables.
   Invalid or unset key returns `nil`.


                                                                *lua-options*
                                                            *lua-vim-options*
                                                                *lua-vim-set*
                                                           *lua-vim-setlocal*

Vim options can be accessed through |vim.o|, which behaves like Vimscript
|:set|.

   Examples: ~

   To set a boolean toggle:
       Vimscript: `set number`
       Lua:       `vim.o.number = true`

   To set a string value:
       Vimscript: `set wildignore=*.o,*.a,__pycache__`
       Lua:       `vim.o.wildignore = '*.o,*.a,__pycache__'`

Similarly, there is |vim.bo| and |vim.wo| for setting buffer-scoped and
window-scoped options. Note that this must NOT be confused with
|local-options| and |:setlocal|. There is also |vim.go| that only accesses the
global value of a |global-local| option, see |:setglobal|.


                                                              *vim.opt_local*
                                                             *vim.opt_global*
                                                                    *vim.opt*


A special interface |vim.opt| exists for conveniently interacting with list-
and map-style options from Lua: It allows accessing them as Lua tables and
offers object-oriented method for adding and removing entries.

   Examples: ~

   The following methods of setting a list-style option are equivalent:
       In Vimscript: >vim
           set wildignore=*.o,*.a,__pycache__
<
       In Lua using `vim.o`: >lua
           vim.o.wildignore = '*.o,*.a,__pycache__'
<
       In Lua using `vim.opt`: >lua
           vim.opt.wildignore = { '*.o', '*.a', '__pycache__' }
<
   To replicate the behavior of |:set+=|, use: >lua

       vim.opt.wildignore:append { "*.pyc", "node_modules" }
<
   To replicate the behavior of |:set^=|, use: >lua

       vim.opt.wildignore:prepend { "new_first_value" }
<
   To replicate the behavior of |:set-=|, use: >lua

       vim.opt.wildignore:remove { "node_modules" }
<
   The following methods of setting a map-style option are equivalent:
       In Vimscript: >vim
           set listchars=space:_,tab:>~
<
       In Lua using `vim.o`: >lua
           vim.o.listchars = 'space:_,tab:>~'
<
       In Lua using `vim.opt`: >lua
           vim.opt.listchars = { space = '_', tab = '>~' }
<

Note that |vim.opt| returns an `Option` object, not the value of the option,
which is accessed through |vim.opt:get()|:

   Examples: ~

   The following methods of getting a list-style option are equivalent:
       In Vimscript: >vim
           echo wildignore
<
       In Lua using `vim.o`: >lua
           print(vim.o.wildignore)
<
       In Lua using `vim.opt`: >lua
           vim.print(vim.opt.wildignore:get())
<

In any of the above examples, to replicate the behavior |:setlocal|, use
`vim.opt_local`. Additionally, to replicate the behavior of |:setglobal|, use
`vim.opt_global`.


Option:append({value})                                      *vim.opt:append()*
   Append a value to string-style options. See |:set+=|

   These are equivalent: >lua
       vim.opt.formatoptions:append('j')
       vim.opt.formatoptions = vim.opt.formatoptions + 'j'
<

   Parameters: ~
     • {value}  (`string`) Value to append

Option:get()                                                   *vim.opt:get()*
   Returns a Lua-representation of the option. Boolean, number and string
   values will be returned in exactly the same fashion.

   For values that are comma-separated lists, an array will be returned with
   the values as entries in the array: >lua
       vim.cmd [[set wildignore=*.pyc,*.o]]

       vim.print(vim.opt.wildignore:get())
       -- { "*.pyc", "*.o", }

       for _, ignore_pattern in ipairs(vim.opt.wildignore:get()) do
           print("Will ignore:", ignore_pattern)
       end
       -- Will ignore: *.pyc
       -- Will ignore: *.o
<

   For values that are comma-separated maps, a table will be returned with
   the names as keys and the values as entries: >lua
       vim.cmd [[set listchars=space:_,tab:>~]]

       vim.print(vim.opt.listchars:get())
       --  { space = "_", tab = ">~", }

       for char, representation in pairs(vim.opt.listchars:get()) do
           print(char, "=>", representation)
       end
<

   For values that are lists of flags, a set will be returned with the flags
   as keys and `true` as entries. >lua
       vim.cmd [[set formatoptions=njtcroql]]

       vim.print(vim.opt.formatoptions:get())
       -- { n = true, j = true, c = true, ... }

       local format_opts = vim.opt.formatoptions:get()
       if format_opts.j then
           print("J is enabled!")
       end
<

   Return: ~
       (`string|integer|boolean?`) value of option

Option:prepend({value})                                    *vim.opt:prepend()*
   Prepend a value to string-style options. See |:set^=|

   These are equivalent: >lua
       vim.opt.wildignore:prepend('*.o')
       vim.opt.wildignore = vim.opt.wildignore ^ '*.o'
<

   Parameters: ~
     • {value}  (`string`) Value to prepend

Option:remove({value})                                      *vim.opt:remove()*
   Remove a value from string-style options. See |:set-=|

   These are equivalent: >lua
       vim.opt.wildignore:remove('*.pyc')
       vim.opt.wildignore = vim.opt.wildignore - '*.pyc'
<

   Parameters: ~
     • {value}  (`string`) Value to remove

vim.bo[{bufnr}]                                                       *vim.bo*
   Get or set buffer-scoped |options| for the buffer with number {bufnr}.
   Like `:setlocal`. If {bufnr} is omitted then the current buffer is used.
   Invalid {bufnr} or key is an error.

   Example: >lua
       local bufnr = vim.api.nvim_get_current_buf()
       vim.bo[bufnr].buflisted = true    -- same as vim.bo.buflisted = true
       print(vim.bo.comments)
       print(vim.bo.baz)                 -- error: invalid key
<

vim.env                                                              *vim.env*
   Environment variables defined in the editor session. See |expand-env| and
   |:let-environment| for the Vimscript behavior. Invalid or unset key
   returns `nil`.

   Example: >lua
       vim.env.FOO = 'bar'
       print(vim.env.TERM)
<

vim.go                                                                *vim.go*
   Get or set global |options|. Like `:setglobal`. Invalid key is an error.

   Note: this is different from |vim.o| because this accesses the global
   option value and thus is mostly useful for use with |global-local|
   options.

   Example: >lua
       vim.go.cmdheight = 4
       print(vim.go.columns)
       print(vim.go.bar)     -- error: invalid key
<

vim.o                                                                  *vim.o*
   Get or set |options|. Works like `:set`, so buffer/window-scoped options
   target the current buffer/window. Invalid key is an error.

   Example: >lua
       vim.o.cmdheight = 4
       print(vim.o.columns)
       print(vim.o.foo)     -- error: invalid key
<

vim.wo[{winid}][{bufnr}]                                              *vim.wo*
   Get or set window-scoped |options| for the window with handle {winid} and
   buffer with number {bufnr}. Like `:setlocal` if setting a |global-local|
   option or if {bufnr} is provided, like `:set` otherwise. If {winid} is
   omitted then the current window is used. Invalid {winid}, {bufnr} or key
   is an error.

   Note: only {bufnr} with value `0` (the current buffer in the window) is
   supported.

   Example: >lua
       local winid = vim.api.nvim_get_current_win()
       vim.wo[winid].number = true    -- same as vim.wo.number = true
       print(vim.wo.foldmarker)
       print(vim.wo.quux)             -- error: invalid key
       vim.wo[winid][0].spell = false -- like ':setlocal nospell'

   Executes Vimscript (|Ex-commands|).

   Can be indexed with a command name to get a function, thus you can write
   `vim.cmd.echo(…)` instead of `vim.cmd{cmd='echo',…}`.

   Examples: >lua
       -- Single command:
       vim.cmd('echo 42')
       -- Multiline script:
       vim.cmd([[
         augroup my.group
           autocmd!
           autocmd FileType c setlocal cindent
         augroup END
       ]])

       -- Ex command :echo "foo". Note: string literals must be double-quoted.
       vim.cmd('echo "foo"')
       vim.cmd { cmd = 'echo', args = { '"foo"' } }
       vim.cmd.echo({ args = { '"foo"' } })
       vim.cmd.echo('"foo"')

       -- Ex command :write! myfile.txt
       vim.cmd('write! myfile.txt')
       vim.cmd { cmd = 'write', args = { 'myfile.txt' }, bang = true }
       vim.cmd.write { args = { 'myfile.txt' }, bang = true }
       vim.cmd.write { 'myfile.txt', bang = true }

       -- Ex command :vertical resize +2
       vim.cmd.resize({ '+2', mods = { vertical = true } })
<

   Parameters: ~
     • {command}  (`string|table`) Command(s) to execute.
                  • The string form supports multiline Vimscript (alias to
                    |nvim_exec2()|, behaves like |:source|).
                  • The table form executes a single command (alias to
                    |nvim_cmd()|).

   See also: ~
     • |ex-cmd-index|

vim.defer_fn({fn}, {timeout})                                 *vim.defer_fn()*
   Defers calling {fn} until {timeout} ms passes.

   Use to do a one-shot timer that calls {fn} Note: The {fn} is
   |vim.schedule()|d automatically, so API functions are safe to call.

   Parameters: ~
     • {fn}       (`function`) Callback to call once `timeout` expires
     • {timeout}  (`integer`) Number of milliseconds to wait before calling
                  `fn`

   Return: ~
       (`uv.uv_timer_t`) timer luv timer object

                                                            *vim.deprecate()*
vim.deprecate({name}, {alternative}, {version}, {plugin}, {backtrace})
   Shows a deprecation message to the user.

   Parameters: ~
     • {name}         (`string`) Deprecated feature (function, API, etc.).
     • {alternative}  (`string?`) Suggested alternative feature.
     • {version}      (`string`) Version when the deprecated function will be
                      removed.
     • {plugin}       (`string?`) Name of the plugin that owns the deprecated
                      feature. Defaults to "Nvim".
     • {backtrace}    (`boolean?`) Prints backtrace. Defaults to true.

   Return: ~
       (`string?`) Deprecated message, or nil if no message was shown.

vim.inspect()                                                  *vim.inspect()*
   Gets a human-readable representation of the given object.

vim.lua_omnifunc({find_start})                            *vim.lua_omnifunc()*
   Omnifunc for completing Lua values from the runtime Lua interpreter,
   similar to the builtin completion for the `:lua` command.

   Activate using `set omnifunc=v:lua.vim.lua_omnifunc` in a Lua buffer.

   Parameters: ~
     • {find_start}  (`1|0`)

vim.notify({msg}, {level}, {opts})                              *vim.notify()*
   Displays a notification to the user.

   This function can be overridden by plugins to display notifications using
   a custom provider (such as the system notification provider). By default,
   writes to |:messages|.

   Parameters: ~
     • {msg}    (`string`) Content of the notification to show to the user.
     • {level}  (`integer?`) One of the values from |vim.log.levels|.

vim.on_key({fn}, {ns_id}, {opts})                               *vim.on_key()*
   Adds Lua function {fn} with namespace id {ns_id} as a listener to every,
   yes every, input key.

   The Nvim command-line option |-w| is related but does not support
   callbacks and cannot be toggled dynamically.

   Note: ~
     • {fn} will be removed on error.
     • {fn} won't be invoked recursively, i.e. if {fn} itself consumes input,
       it won't be invoked for those keys.
     • {fn} will not be cleared by |nvim_buf_clear_namespace()|

   Parameters: ~
     • {fn}     (`fun(key: string, typed: string): string??`) Function
                invoked for every input key, after mappings have been applied
                but before further processing. Arguments {key} and {typed}
                are raw keycodes, where {key} is the key after mappings are
                applied, and {typed} is the key(s) before mappings are
                applied. {typed} may be empty if {key} is produced by
                non-typed key(s) or by the same typed key(s) that produced a
                previous {key}. If {fn} returns an empty string, {key} is
                discarded/ignored, and if {key} is <Cmd> then the
                "<Cmd>…<CR>" sequence is discarded as a whole. When {fn} is
                `nil`, the callback associated with namespace {ns_id} is
                removed.
     • {ns_id}  (`integer?`) Namespace ID. If nil or 0, generates and returns
                a new |nvim_create_namespace()| id.
     • {opts}   (`table?`) Optional parameters

   Return: ~
       (`integer`) Namespace id associated with {fn}. Or count of all
       callbacks if on_key() is called without arguments.

     • |keytrans()|

vim.paste({lines}, {phase})                                      *vim.paste()*
   Paste handler, invoked by |nvim_paste()|.

   Note: This is provided only as a "hook", don't call it directly; call
   |nvim_paste()| instead, which arranges redo (dot-repeat) and invokes
   `vim.paste`.

   Example: To remove ANSI color codes when pasting: >lua
       vim.paste = (function(overridden)
         return function(lines, phase)
           for i,line in ipairs(lines) do
             -- Scrub ANSI color codes from paste input.
             lines[i] = line:gsub('\27%[[0-9;mK]+', '')
           end
           return overridden(lines, phase)
         end
       end)(vim.paste)
<

   Parameters: ~
     • {lines}  (`string[]`) |readfile()|-style list of lines to paste.
                |channel-lines|
     • {phase}  (`-1|1|2|3`) -1: "non-streaming" paste: the call contains all
                lines. If paste is "streamed", `phase` indicates the stream
                state:
                • 1: starts the paste (exactly once)
                • 2: continues the paste (zero or more times)
                • 3: ends the paste (exactly once)

   Return: ~
       (`boolean`) result false if client should cancel the paste.

     • |paste|

vim.print({...})                                                 *vim.print()*
   "Pretty prints" the given arguments and returns them unmodified.

   Example: >lua
       local hl_normal = vim.print(vim.api.nvim_get_hl(0, { name = 'Normal' }))
<

   Parameters: ~
     • {...}  (`any`)

   Return: ~
       (`any`) given arguments.

     • |:=|

vim.schedule_wrap({fn})                                  *vim.schedule_wrap()*
   Returns a function which calls {fn} via |vim.schedule()|.

   The returned function passes all arguments to {fn}.

   Example: >lua
       function notify_readable(_err, readable)
         vim.notify("readable? " .. tostring(readable))
       end
       vim.uv.fs_access(vim.fn.stdpath("config"), "R", vim.schedule_wrap(notify_readable))
<

   Parameters: ~
     • {fn}  (`function`)

   Return: ~
       (`function`)

   See also: ~
     • |lua-loop-callbacks|
     • |vim.schedule()|
     • |vim.in_fast_event()|

                                                        *vim.str_byteindex()*
vim.str_byteindex({s}, {encoding}, {index}, {strict_indexing})
   Convert UTF-32, UTF-16 or UTF-8 {index} to byte index. If
   {strict_indexing} is false then an out of range index will return byte
   length instead of throwing an error.

   Invalid UTF-8 and NUL is treated like in |vim.str_utfindex()|. An {index}
   in the middle of a UTF-16 sequence is rounded upwards to the end of that
   sequence.

   Parameters: ~
     • {s}                (`string`)
     • {encoding}         (`"utf-8"|"utf-16"|"utf-32"`)
     • {index}            (`integer`)
     • {strict_indexing}  (`boolean?`) default: true

   Return: ~
       (`integer`)

                                                         *vim.str_utfindex()*
vim.str_utfindex({s}, {encoding}, {index}, {strict_indexing})
   Convert byte index to UTF-32, UTF-16 or UTF-8 indices. If {index} is not
   supplied, the length of the string is used. All indices are zero-based.

   If {strict_indexing} is false then an out of range index will return
   string length instead of throwing an error. Invalid UTF-8 bytes, and
   embedded surrogates are counted as one code point each. An {index} in the
   middle of a UTF-8 sequence is rounded upwards to the end of that sequence.

   Parameters: ~
     • {s}                (`string`)
     • {encoding}         (`"utf-8"|"utf-16"|"utf-32"`)
     • {index}            (`integer?`)
     • {strict_indexing}  (`boolean?`) default: true

   Return: ~
       (`integer`)

*vim.Ringbuf*

   Fields: ~
     • {clear}  (`fun()`) See |Ringbuf:clear()|.
     • {push}   (`fun(item: T)`) See |Ringbuf:push()|.
     • {pop}    (`fun(): T?`) See |Ringbuf:pop()|.
     • {peek}   (`fun(): T?`) See |Ringbuf:peek()|.


Ringbuf:clear()                                              *Ringbuf:clear()*
   Clear all items

Ringbuf:peek()                                                *Ringbuf:peek()*
   Returns the first unread item without removing it

   Return: ~
       (`any?`)

Ringbuf:pop()                                                  *Ringbuf:pop()*
   Removes and returns the first unread item

   Return: ~
       (`any?`)

Ringbuf:push({item})                                          *Ringbuf:push()*
   Adds an item, overriding the oldest item if the buffer is full.

   Parameters: ~
     • {item}  (`any`)

vim.deep_equal({a}, {b})                                    *vim.deep_equal()*
   Deep compare values for equality

   Tables are compared recursively unless they both provide the `eq`
   metamethod. All other types are compared using the equality `==` operator.

   Parameters: ~
     • {a}  (`any`) First value
     • {b}  (`any`) Second value

   Return: ~
       (`boolean`) `true` if values are equals, else `false`

vim.deepcopy({orig}, {noref})                                 *vim.deepcopy()*
   Returns a deep copy of the given object. Non-table objects are copied as
   in a typical Lua assignment, whereas table objects are copied recursively.
   Functions are naively copied, so functions in the copied table point to
   the same functions as those in the input table. Userdata and threads are
   not copied and will throw an error.

   Note: `noref=true` is much more performant on tables with unique table
   fields, while `noref=false` is more performant on tables that reuse table
   fields.

   Parameters: ~
     • {orig}   (`table`) Table to copy
     • {noref}  (`boolean?`) When `false` (default) a contained table is only
                copied once and all references point to this single copy.
                When `true` every occurrence of a table results in a new
                copy. This also means that a cyclic reference can cause
                `deepcopy()` to fail.

   Return: ~
       (`table`) Table of copied keys and (nested) values.

vim.defaulttable({createfn})                              *vim.defaulttable()*
   Creates a table whose missing keys are provided by {createfn} (like
   Python's "defaultdict").

   If {createfn} is `nil` it defaults to defaulttable() itself, so accessing
   nested keys creates nested tables: >lua
       local a = vim.defaulttable()
       a.b.c = 1
<

   Parameters: ~
     • {createfn}  (`fun(key:any):any?`) Provides the value for a missing
                   `key`.

   Return: ~
       (`table`) Empty table with `__index` metamethod.

vim.endswith({s}, {suffix})                                   *vim.endswith()*
   Tests if `s` ends with `suffix`.

   Parameters: ~
     • {s}       (`string`) String
     • {suffix}  (`string`) Suffix to match

   Return: ~
       (`boolean`) `true` if `suffix` is a suffix of `s`

vim.gsplit({s}, {sep}, {opts})                                  *vim.gsplit()*
   Gets an |iterator| that splits a string at each instance of a separator,
   in "lazy" fashion (as opposed to |vim.split()| which is "eager").

   Example: >lua
       for s in vim.gsplit(':aa::b:', ':', {plain=true}) do
         print(s)
       end
<

   If you want to also inspect the separator itself (instead of discarding
   it), use |string.gmatch()|. Example: >lua
       for word, num in ('foo111bar222'):gmatch('([^0-9]*)(%d*)') do
         print(('word: %s num: %s'):format(word, num))
       end
<

   Parameters: ~
     • {s}     (`string`) String to split
     • {sep}   (`string`) Separator or pattern
     • {opts}  (`table?`) Keyword arguments |kwargs|:
               • {plain}? (`boolean`) Use `sep` literally (as in
                 string.find).
               • {trimempty}? (`boolean`) Discard empty segments at start and
                 end of the sequence.

   Return: ~
       (`fun():string?`) Iterator over the split components

vim.is_callable({f})                                       *vim.is_callable()*
   Returns true if object `f` can be called as a function.

   Parameters: ~
     • {f}  (`any?`) Any object

   Return: ~
       (`boolean`) `true` if `f` is callable, else `false`

vim.isarray({t})                                               *vim.isarray()*
   Tests if `t` is an "array": a table indexed only by integers (potentially
   non-contiguous).

   If the indexes start from 1 and are contiguous then the array is also a
   list. |vim.islist()|

   Empty table `{}` is an array, unless it was created by |vim.empty_dict()|
   or returned as a dict-like |API| or Vimscript result, for example from
   |rpcrequest()| or |vim.fn|.

   Parameters: ~
     • {t}  (`any?`)

   Return: ~
       (`boolean`) `true` if array-like table, else `false`.

vim.islist({t})                                                 *vim.islist()*
   Tests if `t` is a "list": a table indexed only by contiguous integers
   starting from 1 (what |lua-length| calls a "regular array").

   Empty table `{}` is a list, unless it was created by |vim.empty_dict()| or
   returned as a dict-like |API| or Vimscript result, for example from
   |rpcrequest()| or |vim.fn|.

   Parameters: ~
     • {t}  (`any?`)

   Return: ~
       (`boolean`) `true` if list-like table, else `false`.

     • |vim.isarray()|

vim.list.bisect({t}, {val}, {opts})                        *vim.list.bisect()*
   Search for a position in a sorted list {t} where {val} can be inserted
   while keeping the list sorted.

   Use {bound} to determine whether to return the first or the last position,
   defaults to "lower", i.e., the first position.

   NOTE: Behavior is undefined on unsorted lists!

   Example: >lua

       local t = { 1, 2, 2, 3, 3, 3 }
       local first = vim.list.bisect(t, 3)
       -- `first` is `val`'s first index if found,
       -- useful for existence checks.
       print(t[first]) -- 3

       local last = vim.list.bisect(t, 3, { bound = 'upper' })
       -- Note that `last` is 7, not 6,
       -- this is suitable for insertion.

       table.insert(t, last, 4)
       -- t is now { 1, 2, 2, 3, 3, 3, 4 }

       -- You can use lower bound and upper bound together
       -- to obtain the range of occurrences of `val`.

       -- 3 is in [first, last)
       for i = first, last - 1 do
         print(t[i]) -- { 3, 3, 3 }
       end
<

   Parameters: ~
     • {t}     (`any[]`) A comparable list.
     • {val}   (`any`) The value to search.
     • {opts}  (`table?`) A table with the following fields:
               • {lo}? (`integer`, default: `1`) Start index of the list.
               • {hi}? (`integer`, default: `#t + 1`) End index of the list,
                 exclusive.
               • {key}? (`fun(val: any): any`) Optional, compare the return
                 value instead of the {val} itself if provided.
               • {bound}? (`'lower'|'upper'`, default: `'lower'`) Specifies
                 the search variant.
                 • "lower": returns the first position where inserting {val}
                   keeps the list sorted.
                 • "upper": returns the last position where inserting {val}
                   keeps the list sorted..

   Return: ~
       (`integer`) index serves as either the lower bound or the upper bound
       position.

vim.list.unique({t}, {key})                                *vim.list.unique()*
   Removes duplicate values from a list-like table in-place.

   Only the first occurrence of each value is kept. The operation is
   performed in-place and the input table is modified.

   Accepts an optional `key` argument, which if provided is called for each
   value in the list to compute a hash key for uniqueness comparison. This is
   useful for deduplicating table values or complex objects. If `key` returns
   `nil` for a value, that value will be considered unique, even if multiple
   values return `nil`.

   Example: >lua

       local t = {1, 2, 2, 3, 1}
       vim.list.unique(t)
       -- t is now {1, 2, 3}

       local t = { {id=1}, {id=2}, {id=1} }
       vim.list.unique(t, function(x) return x.id end)
       -- t is now { {id=1}, {id=2} }
<

vim.tbl_deep_extend({behavior}, {...})                 *vim.tbl_deep_extend()*
   Merges recursively two or more tables.

   Only values that are empty tables or tables that are not |lua-list|s
   (indexed by consecutive integers starting from 1) are merged recursively.
   This is useful for merging nested tables like default and user
   configurations where lists should be treated as literals (i.e., are
   overwritten instead of merged).

   Parameters: ~
     • {behavior}  (`'error'|'keep'|'force'|fun(key:any, prev_value:any?, value:any): any`)
                   Decides what to do if a key is found in more than one map:
                   • "error": raise an error
                   • "keep": use value from the leftmost map
                   • "force": use value from the rightmost map
                   • If a function, it receives the current key, the previous
                     value in the currently merged table (if present), the
                     current value and should return the value for the given
                     key in the merged table.
     • {...}       (`table`) Two or more tables

   Return: ~
       (`table`) Merged table

                                                             *vim.validate()*
vim.validate({name}, {value}, {validator}, {optional}, {message})
   Validate function arguments.

   This function has two valid forms:
   1. `vim.validate(name, value, validator[, optional][, message])`
      Validates that argument {name} with value {value} satisfies
      {validator}. If {optional} is given and is `true`, then {value} may be
      `nil`. If {message} is given, then it is used as the expected type in
      the error message.
      Example: >lua
        function vim.startswith(s, prefix)
         vim.validate('s', s, 'string')
         vim.validate('prefix', prefix, 'string')
         -- ...
       end
<

   2. `vim.validate(spec)` (deprecated) where `spec` is of type
      `table<string,[value:any, validator: vim.validate.Validator, optional_or_msg? : boolean|string]>)`
      Validates a argument specification. Specs are evaluated in alphanumeric
      order, until the first failure.
      Example: >lua
        function user.new(name, age, hobbies)
         vim.validate{
           name={name, 'string'},
           age={age, 'number'},
           hobbies={hobbies, 'table'},
         }
         -- ...
       end
<

   Examples with explicit argument values (can be run directly): >lua
       vim.validate('arg1', {'foo'}, 'table')
          --> NOP (success)
       vim.validate('arg2', 'foo', 'string')
          --> NOP (success)

       vim.validate('arg1', 1, 'table')
          --> error('arg1: expected table, got number')

       vim.validate('arg1', 3, function(a) return (a % 2) == 0 end, 'even number')
          --> error('arg1: expected even number, got 3')
<

   If multiple types are valid they can be given as a list. >lua
       vim.validate('arg1', {'foo'}, {'table', 'string'})
       vim.validate('arg2', 'foo', {'table', 'string'})
       -- NOP (success)

       vim.validate('arg1', 1, {'string', 'table'})
       -- error('arg1: expected string|table, got number')
<

   Note: ~
     • `validator` set to a value returned by |lua-type()| provides the best
       performance.

   Parameters: ~
     • {name}       (`string`) Argument name
     • {value}      (`any`) Argument value
     • {validator}  (`vim.validate.Validator`)
                    • (`string|string[]`): Any value that can be returned
                      from |lua-type()| in addition to `'callable'`:
                      `'boolean'`, `'callable'`, `'function'`, `'nil'`,
                      `'number'`, `'string'`, `'table'`, `'thread'`,
                      `'userdata'`.
                    • (`fun(val:any): boolean, string?`) A function that
                      returns a boolean and an optional string message.
     • {optional}   (`boolean?`) Argument is optional (may be omitted)
     • {message}    (`string?`) message when validation fails

   Overloads: ~
     • `fun(name: string, val: any, validator: vim.validate.Validator, message: string)`
     • `fun(spec: table<string,[any, vim.validate.Validator, boolean|string]>)`

Lua module: vim.filetype                                        *vim.filetype*

vim.filetype.add({filetypes})                             *vim.filetype.add()*
   Add new filetype mappings.

   Filetype mappings can be added either by extension or by filename (either
   the "tail" or the full file path). The full file path is checked first,
   followed by the file name. If a match is not found using the filename,
   then the filename is matched against the list of |lua-pattern|s (sorted by
   priority) until a match is found. Lastly, if pattern matching does not
   find a filetype, then the file extension is used.

   The filetype can be either a string (in which case it is used as the
   filetype directly) or a function. If a function, it takes the full path
   and buffer number of the file as arguments (along with captures from the
   matched pattern, if any) and should return a string that will be used as
   the buffer's filetype. Optionally, the function can return a second
   function value which, when called, modifies the state of the buffer. This
   can be used to, for example, set filetype-specific buffer variables. This
   function will be called by Nvim before setting the buffer's filetype.

   Filename patterns can specify an optional priority to resolve cases when a
   file path matches multiple patterns. Higher priorities are matched first.
   When omitted, the priority defaults to 0. A pattern can contain
   environment variables of the form "${SOME_VAR}" that will be automatically
   expanded. If the environment variable is not set, the pattern won't be
   matched.

   See $VIMRUNTIME/lua/vim/filetype.lua for more examples.

   Example: >lua
       vim.filetype.add({
         extension = {
           foo = 'fooscript',
           bar = function(path, bufnr)
             if some_condition() then
               return 'barscript', function(bufnr)
                 -- Set a buffer variable
                 vim.b[bufnr].barscript_version = 2
               end
             end
             return 'bar'
           end,
         },
         filename = {
           ['.foorc'] = 'toml',
           ['/etc/foo/config'] = 'toml',
         },
         pattern = {
           ['.*/etc/foo/.*'] = 'fooscript',
           -- Using an optional priority
           ['.*/etc/foo/.*%.conf'] = { 'dosini', { priority = 10 } },
           -- A pattern containing an environment variable
           ['${XDG_CONFIG_HOME}/foo/git'] = 'git',
           ['.*README.(%a+)'] = function(path, bufnr, ext)
             if ext == 'md' then
               return 'markdown'
             elseif ext == 'rst' then
               return 'rst'
             end
           end,
         },
       })
<

   To add a fallback match on contents, use >lua
       vim.filetype.add {
         pattern = {
           ['.*'] = {
             function(path, bufnr)
               local content = vim.api.nvim_buf_get_lines(bufnr, 0, 1, false)[1] or ''
               if vim.regex([[^#!.*\\<mine\\>]]):match_str(content) ~= nil then
                 return 'mine'
               elseif vim.regex([[\\<drawing\\>]]):match_str(content) ~= nil then
                 return 'drawing'
               end
             end,
             { priority = -math.huge },
           },
         },
       }
<

   Parameters: ~
     • {filetypes}  (`table`) A table containing new filetype maps (see
                    example).
                    • {pattern}? (`vim.filetype.mapping`)
                    • {extension}? (`vim.filetype.mapping`)
                    • {filename}? (`vim.filetype.mapping`)

                                                  *vim.filetype.get_option()*
vim.filetype.get_option({filetype}, {option})
   Get the default option value for a {filetype}.

   The returned value is what would be set in a new buffer after 'filetype'
   is set, meaning it should respect all FileType autocmds and ftplugin
   files.

   Example: >lua
       vim.filetype.get_option('vim', 'commentstring')
<

   Note: this uses |nvim_get_option_value()| but caches the result. This
   means |ftplugin| and |FileType| autocommands are only triggered once and
   may not reflect later changes.

   Attributes: ~
       Since: 0.9.0

   Parameters: ~
     • {filetype}  (`string`) Filetype
     • {option}    (`string`) Option name

   Return: ~
       (`string|boolean|integer`) Option value

vim.filetype.match({args})                              *vim.filetype.match()*
   Perform filetype detection.

   The filetype can be detected using one of three methods:
   1. Using an existing buffer

   2. Using only a file name

   3. Using only file contents

   Of these, option 1 provides the most accurate result as it uses both the
   buffer's filename and (optionally) the buffer contents. Options 2 and 3
   can be used without an existing buffer, but may not always provide a match
   in cases where the filename (or contents) cannot unambiguously determine
   the filetype.

   Each of the three options is specified using a key to the single argument
   of this function. Example: >lua
       -- Using a buffer number
       vim.filetype.match({ buf = 42 })

       -- Override the filename of the given buffer
       vim.filetype.match({ buf = 42, filename = 'foo.c' })

       -- Using a filename without a buffer
       vim.filetype.match({ filename = 'main.lua' })

       -- Using file contents
       vim.filetype.match({ contents = {'#!/usr/bin/env bash'} })
<

   Parameters: ~
     • {args}  (`table`) Table specifying which matching strategy to use.
               Accepted keys are:
               • {buf}? (`integer`) Buffer number to use for matching.
                 Mutually exclusive with {contents}
               • {filename}? (`string`) Filename to use for matching. When
                 {buf} is given, defaults to the filename of the given buffer
                 number. The file need not actually exist in the filesystem.
                 When used without {buf} only the name of the file is used
                 for filetype matching. This may result in failure to detect
                 the filetype in cases where the filename alone is not enough
                 to disambiguate the filetype.
               • {contents}? (`string[]`) An array of lines representing file
                 contents to use for matching. Can be used with {filename}.
                 Mutually exclusive with {buf}.

   Return (multiple): ~
       (`string?`) The matched filetype, if any.
       (`function?`) A function `fun(buf: integer)` that modifies buffer
       state when called (for example, to set some filetype specific buffer
       variables).
       (`boolean?`) true if a match was found by falling back to a generic
       filetype (i.e., ".conf"), which indicates the filetype should be set
       with `:setf FALLBACK conf`. See |:setfiletype|.

   then the search traverses upward through parent directories; otherwise,
   the search traverses downward. Note that downward searches are recursive
   and may search through many directories! If {stop} is non-nil, then the
   search stops when the directory given in {stop} is reached. The search
   terminates when {limit} (default 1) matches are found. You can set {type}
   to "file", "directory", "link", "socket", "char", "block", or "fifo" to
   narrow the search to find only that type.

   Examples: >lua
       -- List all test directories under the runtime directory.
       local dirs = vim.fs.find(
         { 'test', 'tst', 'testdir' },
         { limit = math.huge, type = 'directory', path = './runtime/' }
       )

       -- Get all "lib/*.cpp" and "lib/*.hpp" files, using Lua patterns.
       -- Or use `vim.glob.to_lpeg(…):match(…)` for glob/wildcard matching.
       local files = vim.fs.find(function(name, path)
         return name:match('.*%.[ch]pp$') and path:match('[/\\]lib$')
       end, { limit = math.huge, type = 'file' })

   Parameters: ~
     • {names}  (`string|string[]|fun(name: string, path: string): boolean`)
                Names of the items to find. Must be base names, paths and
                globs are not supported when {names} is a string or a table.
                If {names} is a function, it is called for each traversed
                item with args:
                • name: base name of the current item
                • path: full path of the current item

                The function should return `true` if the given item is
                considered a match.
     • {opts}   (`table?`) Optional keyword arguments:
                • {path}? (`string`) Path to begin searching from, defaults
                  to |current-directory|. Not expanded.
                • {upward}? (`boolean`, default: `false`) Search upward
                  through parent directories. Otherwise, search child
                  directories (recursively).
                • {stop}? (`string`) Stop searching when this directory is
                  reached. The directory itself is not searched.
                • {type}? (`string`) Find only items of the given type. If
                  omitted, all items that match {names} are included.
                • {limit}? (`number`, default: `1`) Stop searching after this
                  many matches. Use `math.huge` for "unlimited".
                • {follow}? (`boolean`, default: `false`) Follow symbolic
                  links.

   Return: ~
       (`string[]`) Normalized paths |vim.fs.normalize()| of all matching
       items

vim.fs.joinpath({...})                                     *vim.fs.joinpath()*
   Concatenates partial paths (one absolute or relative path followed by zero
   or more relative paths). Slashes are normalized: redundant slashes are
   removed, and (on Windows) backslashes are replaced with forward-slashes.
   Empty segments are removed. Paths are not expanded/resolved.

   Examples:
   • "foo/", "/bar" => "foo/bar"
   • "", "after/plugin" => "after/plugin"
   • Windows: "a\foo\", "\bar" => "a/foo/bar"

   Parameters: ~
     • {...}  (`string`)

   Return: ~
       (`string`)

vim.fs.normalize({path}, {opts})                          *vim.fs.normalize()*
   Normalize a path to a standard format. A tilde (~) character at the
   beginning of the path is expanded to the user's home directory and
   environment variables are also expanded. "." and ".." components are also
   resolved, except when the path is relative and trying to resolve it would
   result in an absolute path.
   • "." as the only part in a relative path:
     • "." => "."
     • "././" => "."
   • ".." when it leads outside the current directory
     • "foo/../../bar" => "../bar"
     • "../../foo" => "../../foo"
   • ".." in the root directory returns the root directory.
     • "/../../" => "/"

   On Windows, backslash (\) characters are converted to forward slashes (/).

   Examples: >lua
       [[C:\Users\jdoe]]                         => "C:/Users/jdoe"
       "~/src/neovim"                            => "/home/jdoe/src/neovim"
       "$XDG_CONFIG_HOME/nvim/init.vim"          => "/Users/jdoe/.config/nvim/init.vim"
       "~/src/nvim/api/../tui/./tui.c"           => "/home/jdoe/src/nvim/tui/tui.c"
       "./foo/bar"                               => "foo/bar"
       "foo/../../../bar"                        => "../../bar"
       "/home/jdoe/../../../bar"                 => "/bar"
       "C:foo/../../baz"                         => "C:../baz"
       "C:/foo/../../baz"                        => "C:/baz"

vim.fs.parents({start})                                     *vim.fs.parents()*
   Iterate over all the parents of the given path (not expanded/resolved, the
   caller must do that).

   Example: >lua
       local root_dir

vim.fs.root({source}, {marker})                                *vim.fs.root()*
   Find the first parent directory containing a specific "marker", relative
   to a file path or buffer.

   If the buffer is unnamed (has no backing file) or has a non-empty
   'buftype' then the search begins from Nvim's |current-directory|.

   Examples: >lua
       -- Find the root of a Python project, starting from file 'main.py'
       vim.fs.root(vim.fs.joinpath(vim.env.PWD, 'main.py'), {'pyproject.toml', 'setup.py' })

       -- Find the root of a git repository
       vim.fs.root(0, '.git')

       -- Find the parent directory containing any file with a .csproj extension
       vim.fs.root(0, function(name, path)
         return name:match('%.csproj$') ~= nil
       end)

       -- Find the first ancestor directory containing EITHER "stylua.toml" or ".luarc.json"; if
       -- not found, find the first ancestor containing ".git":

                 to begin the search from.
     • {marker}  (`(string|string[]|fun(name: string, path: string): boolean)[]|string|fun(name: string, path: string): boolean`)
                 Filename, function, or list thereof, that decides how to
                 find the root. To indicate "equal priority", specify items
                 in a nested list `{ { 'a.txt', 'b.lua' }, … }`. A function
                 item must return true if `name` and `path` are a match. Each
                 item (which may itself be a nested list) is evaluated
                 in-order against all ancestors, until a match is found.

   Return: ~
       (`string?`) Directory path containing one of the given markers, or nil
       if no directory was found.

Lua module: vim.glob                                                *vim.glob*

Glob-to-LPeg Converter (Peglob) This module converts glob patterns to LPeg
patterns according to the LSP 3.17 specification:
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#pattern

Glob grammar overview:
• `*` to match zero or more characters in a path segment
• `?` to match on one character in a path segment
• `**` to match any number of path segments, including none
• `{}` to group conditions (e.g. `*.{ts,js}` matches TypeScript and JavaScript
 files)
• `[]` to declare a range of characters to match in a path segment (e.g.,
 `example.[0-9]` to match on `example.0`, `example.1`, …)
• `[!...]` to negate a range of characters to match in a path segment (e.g.,
 `example.[!0-9]` to match on `example.a`, `example.b`, but not `example.0`)

Additional constraints:
• A Glob pattern must match an entire path, with partial matches considered
 failures.
• The pattern only determines success or failure, without specifying which
 parts correspond to which characters.
• A path segment is the portion of a path between two adjacent path separators
 (`/`), or between the start/end of the path and the nearest separator.
• The `**` (globstar) pattern matches zero or more path segments, including
 intervening separators (`/`). Within pattern strings, `**` must be delimited
 by path separators (`/`) or pattern boundaries and cannot be adjacent to any
 characters other than `/`. If `**` is not the final element, it must be
 followed by `/`.
• `{}` (braced conditions) contains valid Glob patterns as branches, separated
 by commas. Commas are exclusively used for separating branches and cannot
 appear within a branch for any other purpose. Nested `{}` structures are
 allowed, but `{}` must contain at least two branches—zero or one branch is
 not permitted.
• In `[]` or `[!...]`, a character range consists of character intervals
 (e.g., `a-z`) or individual characters (e.g., `w`). A range including `/`
 won’t match that character.


vim.glob.to_lpeg({pattern})                               *vim.glob.to_lpeg()*

Lua module: vim.iter                                                *vim.iter*

*vim.iter()* is an interface for |iterable|s: it wraps a table or function
argument into an *Iter* object with methods (such as |Iter:filter()| and
|Iter:map()|) that transform the underlying source data. These methods can be
chained to create iterator "pipelines": the output of each pipeline stage is
input to the next stage. The first stage depends on the type passed to
`vim.iter()`:
• Lists or arrays (|lua-list|) yield only the value of each element.
 • Holes (nil values) are allowed (but discarded).
 • Use pairs() to treat array/list tables as dicts (preserve holes and
   non-contiguous integer keys): `vim.iter(pairs(…))`.
 • Use |Iter:enumerate()| to also pass the index to the next stage.
   • Or initialize with ipairs(): `vim.iter(ipairs(…))`.
• Non-list tables (|lua-dict|) yield both the key and value of each element.
• Function |iterator|s yield all values returned by the underlying function.
• Tables with a |__call()| metamethod are treated as function iterators.

The iterator pipeline terminates when the underlying |iterable| is exhausted
(for function iterators this means it returned nil).

Note: `vim.iter()` scans table input to decide if it is a list or a dict; to
avoid this cost you can wrap the table with an iterator e.g.
`vim.iter(ipairs({…}))`, but that precludes the use of |list-iterator|
operations such as |Iter:rev()|).

Examples: >lua
   local it = vim.iter({ 1, 2, 3, 4, 5 })
   it:map(function(v)
     return v * 3
   end)
   it:rev()
   it:skip(2)
   it:totable()
   -- { 9, 6, 3 }

   -- ipairs() is a function iterator which returns both the index (i) and the value (v)
   vim.iter(ipairs({ 1, 2, 3, 4, 5 })):map(function(i, v)
     if i > 2 then return v end
   end):totable()
   -- { 3, 4, 5 }

   local it = vim.iter(vim.gsplit('1,2,3,4,5', ','))
   it:map(function(s) return tonumber(s) end)
   for i, d in it:enumerate() do
     print(string.format("Column %d is %d", i, d))
   end
   -- Column 1 is 1
   -- Column 2 is 2
   -- Column 3 is 3
   -- Column 4 is 4
   -- Column 5 is 5

   vim.iter({ a = 1, b = 2, c = 3, z = 26 }):any(function(k, v)
     return k == 'z'
   end)
   -- true

   local rb = vim.ringbuf(3)
   rb:push("a")
   rb:push("b")
   vim.iter(rb):totable()
   -- { "a", "b" }

Iter:all({pred})                                                  *Iter:all()*
   Returns true if all items in the iterator match the given predicate.

   Parameters: ~
     • {pred}  (`fun(...):boolean`) Predicate function. Takes all values
               returned from the previous stage in the pipeline as arguments
               and returns true if the predicate matches.

Iter:any({pred})                                                  *Iter:any()*
   Returns true if any of the items in the iterator match the given
   predicate.

   Parameters: ~
     • {pred}  (`fun(...):boolean`) Predicate function. Takes all values
               returned from the previous stage in the pipeline as arguments
               and returns true if the predicate matches.

Iter:each({f})                                                   *Iter:each()*
   Calls a function once for each item in the pipeline, draining the
   iterator.

   For functions with side effects. To modify the values in the iterator, use
   |Iter:map()|.

   Parameters: ~
     • {f}  (`fun(...)`) Function to execute for each item in the pipeline.
            Takes all of the values returned by the previous stage in the
            pipeline as arguments.

Iter:enumerate()                                            *Iter:enumerate()*
   Yields the item index (count) and value for each item of an iterator
   pipeline.

   For list tables, this is more efficient: >lua
       vim.iter(ipairs(t))
<

   instead of: >lua
       vim.iter(t):enumerate()
<

   Example: >lua

       local it = vim.iter(vim.gsplit('abc', '')):enumerate()
       it:next()
       -- 1	'a'
       it:next()
       -- 2	'b'
       it:next()
       -- 3	'c'
<

   Return: ~
       (`Iter`)

Iter:filter({f})                                               *Iter:filter()*
   Filters an iterator pipeline.

   Example: >lua
       local bufs = vim.iter(vim.api.nvim_list_bufs()):filter(vim.api.nvim_buf_is_loaded)
<

   Parameters: ~
     • {f}  (`fun(...):boolean`) Takes all values returned from the previous
            stage in the pipeline and returns false or nil if the current
            iterator element should be removed.

   Return: ~
       (`Iter`)

Iter:find({f})                                                   *Iter:find()*
   Find the first value in the iterator that satisfies the given predicate.

   Advances the iterator. Returns nil and drains the iterator if no value is
   found.

   Examples: >lua

       local it = vim.iter({ 3, 6, 9, 12 })
       it:find(12)
       -- 12

       local it = vim.iter({ 3, 6, 9, 12 })

         if v % 2 == 0 then
           return v * 3
         end

Iter:skip({n})                                                   *Iter:skip()*
   Skips `n` values of an iterator pipeline, or skips values while a
   predicate returns |lua-truthy|.

   When a predicate is used, skipping stops at the first value for which the
   predicate returns non-truthy. That value is not consumed and will be
   returned by the next call to |Iter:next()|

Iter:take({n})                                                   *Iter:take()*
   Transforms an iterator to yield only the first n values, or all values
   satisfying a predicate.

   Example: >lua
       local it = vim.iter({ 1, 2, 3, 4 }):take(2)
       it:next()
       -- 1
       it:next()
       -- 2
       it:next()
       -- nil

       local function pred(x) return x < 2 end
       local it2 = vim.iter({ 1, 2, 3, 4 }):take(pred)

   Parameters: ~
     • {n}  (`integer|fun(...):boolean`) Number of values to take or a
            predicate.

   Return: ~
       (`Iter`)

Iter:totable()                                                *Iter:totable()*
   Collect the iterator into a table.

   The resulting table depends on the initial source in the iterator
   pipeline. Array-like tables and function iterators will be collected into
   an array-like table. If multiple values are returned from the final stage
   in the iterator pipeline, each value will be included in a table.

   Examples: >lua
       vim.iter(string.gmatch('100 20 50', '%d+')):map(tonumber):totable()
       -- { 100, 20, 50 }

       vim.iter({ 1, 2, 3 }):map(function(v) return v, 2 * v end):totable()
       -- { { 1, 2 }, { 2, 4 }, { 3, 6 } }

       vim.iter({ a = 1, b = 2, c = 3 }):filter(function(k, v) return v % 2 ~= 0 end):totable()
       -- { { 'a', 1 }, { 'c', 3 } }
<

   The generated table is an array-like table with consecutive, numeric
   indices. To create a map-like table with arbitrary keys, use
   |Iter:fold()|.

   Return: ~
       (`table`)

Iter:unique({key})                                             *Iter:unique()*
   Removes duplicate values from an iterator pipeline.

   Only the first occurrence of each value is kept.

   Accepts an optional `key` argument, which if provided is called for each
   value in the iterator to compute a hash key for uniqueness comparison.
   This is useful for deduplicating table values or complex objects. If `key`
   returns `nil` for a value, that value will be considered unique, even if
   multiple values return `nil`.

   If a function-based iterator returns multiple arguments, uniqueness is
   checked based on the first return value. To change this behavior, specify
   `key`.

   Examples: >lua
       vim.iter({ 1, 2, 2, 3, 2 }):unique():totable()
       -- { 1, 2, 3 }

       vim.iter({ {id=1}, {id=2}, {id=1} })
         :unique(function(x)
           return x.id
         end)
         :totable()
       -- { {id=1}, {id=2} }
<

   Parameters: ~
     • {key}  (`fun(...):any?`) Optional hash function to determine
              uniqueness of values.

   Return: ~
       (`Iter`)

                 `nil` instead of |vim.NIL|.
               • {skip_comments}? (`boolean`, default: `false`) Allows
                 JavaScript-style comments within JSON data. Comments are
                 treated as whitespace and may appear anywhere whitespace is
                 valid in JSON. Supports single-line comments beginning with
                 '//' and block comments enclosed with '/' and '/'.

   object.) >lua
       function _G.fmt_json()
         local indent = vim.bo.expandtab and (' '):rep(vim.o.shiftwidth) or '\t'
         local lines = vim.api.nvim_buf_get_lines(0, vim.v.lnum - 1, vim.v.lnum + vim.v.count - 1, true)

         local stringified = vim.json.encode(o, { indent = indent, sort_keys = true })
         lines = vim.split(stringified, '\n')
         vim.api.nvim_buf_set_lines(0, vim.v.lnum - 1, vim.v.count, true, lines)

                 characters "/" in string values.
               • {indent}? (`string`, default: `""`) If non-empty, the
                 returned JSON is formatted with newlines and whitespace,
                 where `indent` defines the whitespace at each nesting level.
               • {sort_keys}? (`boolean`, default: `false`) Sort object keys
                 in alphabetical order.

Lua module: vim.lpeg                                                *vim.lpeg*


LPeg is a pattern-matching library for Lua, based on Parsing Expression
Grammars (PEGs). https://bford.info/packrat/

                                                  *lua-lpeg* *vim.lpeg.Pattern*
The LPeg library for parsing expression grammars is included as `vim.lpeg`
(https://www.inf.puc-rio.br/~roberto/lpeg/).

In addition, its regex-like interface is available as |vim.re|
(https://www.inf.puc-rio.br/~roberto/lpeg/re.html).



Pattern:match({subject}, {init}, {...})                      *Pattern:match()*
   Matches the given `pattern` against the `subject` string. If the match
   succeeds, returns the index in the subject of the first character after
   the match, or the captured values (if the pattern captured any value). An
   optional numeric argument `init` makes the match start at that position in
   the subject string. As usual in Lua libraries, a negative value counts
   from the end. Unlike typical pattern-matching functions, `match` works
   only in anchored mode; that is, it tries to match the pattern with a
   prefix of the given subject string (at position `init`), not with an
   arbitrary substring of the subject. So, if we want to find a pattern
   anywhere in a string, we must either write a loop in Lua or write a
   pattern that matches anywhere.

   Example: >lua
       local pattern = lpeg.R('az') ^ 1 * -1
       assert(pattern:match('hello') == 6)
       assert(lpeg.match(pattern, 'hello') == 6)
       assert(pattern:match('1 hello') == nil)
<

   Parameters: ~
     • {subject}  (`string`)
     • {init}     (`integer?`)
     • {...}      (`any`)

   Return: ~
       (`any`) ...

vim.lpeg.B({pattern})                                           *vim.lpeg.B()*
   Returns a pattern that matches only if the input string at the current
   position is preceded by `patt`. Pattern `patt` must match only strings
   with some fixed length, and it cannot contain captures. Like the `and`
   predicate, this pattern never consumes any input, independently of success
   or failure.

   Parameters: ~
     • {pattern}  (`vim.lpeg.Pattern|string|integer|boolean|table`)

   Return: ~
       (`vim.lpeg.Pattern`)

vim.lpeg.C({patt})                                              *vim.lpeg.C()*
   Creates a simple capture, which captures the substring of the subject that
   matches `patt`. The captured value is a string. If `patt` has other
   captures, their values are returned after this one.

   Example: >lua
       local function split (s, sep)
         sep = lpeg.P(sep)
         local elem = lpeg.C((1 - sep) ^ 0)
         local p = elem * (sep * elem) ^ 0
         return lpeg.match(p, s)
       end
       local a, b, c = split('a,b,c', ',')
       assert(a == 'a')
       assert(b == 'b')
       assert(c == 'c')
<

   Parameters: ~
     • {patt}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Carg({n})                                           *vim.lpeg.Carg()*
   Creates an argument capture. This pattern matches the empty string and
   produces the value given as the nth extra argument given in the call to
   `lpeg.match`.

   Parameters: ~
     • {n}  (`integer`)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Cb({name})                                            *vim.lpeg.Cb()*
   Creates a back capture. This pattern matches the empty string and produces
   the values produced by the most recent group capture named `name` (where
   `name` can be any Lua value). Most recent means the last complete
   outermost group capture with the given name. A Complete capture means that
   the entire pattern corresponding to the capture has matched. An Outermost
   capture means that the capture is not inside another complete capture. In
   the same way that LPeg does not specify when it evaluates captures, it
   does not specify whether it reuses values previously produced by the group
   or re-evaluates them.

   Parameters: ~
     • {name}  (`any`)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Cc({...})                                             *vim.lpeg.Cc()*
   Creates a constant capture. This pattern matches the empty string and
   produces all given values as its captured values.

   Parameters: ~
     • {...}  (`any`)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Cf({patt}, {func})                                    *vim.lpeg.Cf()*
   Creates a fold capture. If `patt` produces a list of captures C1 C2 ...
   Cn, this capture will produce the value
   `func(...func(func(C1, C2), C3)...,Cn)`, that is, it will fold (or
   accumulate, or reduce) the captures from `patt` using function `func`.
   This capture assumes that `patt` should produce at least one capture with
   at least one value (of any type), which becomes the initial value of an
   accumulator. (If you need a specific initial value, you may prefix a
   constant capture to `patt`.) For each subsequent capture, LPeg calls
   `func` with this accumulator as the first argument and all values produced
   by the capture as extra arguments; the first result from this call becomes
   the new value for the accumulator. The final value of the accumulator
   becomes the captured value.

   Example: >lua
       local number = lpeg.R('09') ^ 1 / tonumber
       local list = number * (',' * number) ^ 0
       local function add(acc, newvalue) return acc + newvalue end
       local sum = lpeg.Cf(list, add)
       assert(sum:match('10,30,43') == 83)
<

   Parameters: ~
     • {patt}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)
     • {func}  (`fun(acc, newvalue)`)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Cg({patt}, {name})                                    *vim.lpeg.Cg()*
   Creates a group capture. It groups all values returned by `patt` into a
   single capture. The group may be anonymous (if no name is given) or named
   with the given name (which can be any non-nil Lua value).

   Parameters: ~
     • {patt}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)
     • {name}  (`string?`)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Cmt({patt}, {fn})                                    *vim.lpeg.Cmt()*
   Creates a match-time capture. Unlike all other captures, this one is
   evaluated immediately when a match occurs (even if it is part of a larger
   pattern that fails later). It forces the immediate evaluation of all its
   nested captures and then calls `function`. The given function gets as
   arguments the entire subject, the current position (after the match of
   `patt`), plus any capture values produced by `patt`. The first value
   returned by `function` defines how the match happens. If the call returns
   a number, the match succeeds and the returned number becomes the new
   current position. (Assuming a subject sand current position `i`, the
   returned number must be in the range `[i, len(s) + 1]`.) If the call
   returns `true`, the match succeeds without consuming any input (so, to
   return true is equivalent to return `i`). If the call returns `false`,
   `nil`, or no value, the match fails. Any extra values returned by the
   function become the values produced by the capture.

   Parameters: ~
     • {patt}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)
     • {fn}    (`fun(s: string, i: integer, ...: any)`) (position:
               boolean|integer, ...: any)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Cp()                                                  *vim.lpeg.Cp()*
   Creates a position capture. It matches the empty string and captures the
   position in the subject where the match occurs. The captured value is a
   number.

   Example: >lua
       local I = lpeg.Cp()
       local function anywhere(p) return lpeg.P({I * p * I + 1 * lpeg.V(1)}) end
       local match_start, match_end = anywhere('world'):match('hello world!')
       assert(match_start == 7)
       assert(match_end == 12)
<

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Cs({patt})                                            *vim.lpeg.Cs()*
   Creates a substitution capture. This function creates a substitution
   capture, which captures the substring of the subject that matches `patt`,
   with substitutions. For any capture inside `patt` with a value, the
   substring that matched the capture is replaced by the capture value (which
   should be a string). The final captured value is the string resulting from
   all replacements.

   Example: >lua
       local function gsub (s, patt, repl)
         patt = lpeg.P(patt)
         patt = lpeg.Cs((patt / repl + 1) ^ 0)
         return lpeg.match(patt, s)
       end
       assert(gsub('Hello, xxx!', 'xxx', 'World') == 'Hello, World!')
<

   Parameters: ~
     • {patt}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.Ct({patt})                                            *vim.lpeg.Ct()*
   Creates a table capture. This capture returns a table with all values from
   all anonymous captures made by `patt` inside this table in successive
   integer keys, starting at 1. Moreover, for each named capture group
   created by `patt`, the first value of the group is put into the table with
   the group name as its key. The captured value is only the table.

   Parameters: ~
     • {patt}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)

   Return: ~
       (`vim.lpeg.Capture`)

vim.lpeg.locale({tab})                                     *vim.lpeg.locale()*
   Returns a table with patterns for matching some character classes
   according to the current locale. The table has fields named `alnum`,
   `alpha`, `cntrl`, `digit`, `graph`, `lower`, `print`, `punct`, `space`,
   `upper`, and `xdigit`, each one containing a correspondent pattern. Each
   pattern matches any single character that belongs to its class. If called
   with an argument `table`, then it creates those fields inside the given
   table and returns that table.

   Example: >lua
       lpeg.locale(lpeg)
       local space = lpeg.space ^ 0
       local name = lpeg.C(lpeg.alpha ^ 1) * space
       local sep = lpeg.S(',;') * space
       local pair = lpeg.Cg(name * '=' * space * name) * sep ^ -1
       local list = lpeg.Cf(lpeg.Ct('') * pair ^ 0, rawset)
       local t = list:match('a=b, c = hi; next = pi')
       assert(t.a == 'b')
       assert(t.c == 'hi')
       assert(t.next == 'pi')
       local locale = lpeg.locale()
       assert(type(locale.digit) == 'userdata')
<

   Parameters: ~
     • {tab}  (`table?`)

   Return: ~
       (`vim.lpeg.Locale`)

vim.lpeg.match({pattern}, {subject}, {init}, {...})         *vim.lpeg.match()*
   Matches the given `pattern` against the `subject` string. If the match
   succeeds, returns the index in the subject of the first character after
   the match, or the captured values (if the pattern captured any value). An
   optional numeric argument `init` makes the match start at that position in
   the subject string. As usual in Lua libraries, a negative value counts
   from the end. Unlike typical pattern-matching functions, `match` works
   only in anchored mode; that is, it tries to match the pattern with a
   prefix of the given subject string (at position `init`), not with an
   arbitrary substring of the subject. So, if we want to find a pattern
   anywhere in a string, we must either write a loop in Lua or write a
   pattern that matches anywhere.

   Example: >lua
       local pattern = lpeg.R('az') ^ 1 * -1
       assert(pattern:match('hello') == 6)
       assert(lpeg.match(pattern, 'hello') == 6)
       assert(pattern:match('1 hello') == nil)
<

   Parameters: ~
     • {pattern}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)
     • {subject}  (`string`)
     • {init}     (`integer?`)
     • {...}      (`any`)

   Return: ~
       (`any`) ...

vim.lpeg.P({value})                                             *vim.lpeg.P()*
   Converts the given value into a proper pattern. The following rules are
   applied:
   • If the argument is a pattern, it is returned unmodified.
   • If the argument is a string, it is translated to a pattern that matches
     the string literally.
   • If the argument is a non-negative number `n`, the result is a pattern
     that matches exactly `n` characters.
   • If the argument is a negative number `-n`, the result is a pattern that
     succeeds only if the input string has less than `n` characters left:
     `lpeg.P(-n)` is equivalent to `-lpeg.P(n)` (see the unary minus
     operation).
   • If the argument is a boolean, the result is a pattern that always
     succeeds or always fails (according to the boolean value), without
     consuming any input.
   • If the argument is a table, it is interpreted as a grammar (see
     Grammars).
   • If the argument is a function, returns a pattern equivalent to a
     match-time capture over the empty string.

   Parameters: ~
     • {value}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)

   Return: ~
       (`vim.lpeg.Pattern`)

vim.lpeg.R({...})                                               *vim.lpeg.R()*
   Returns a pattern that matches any single character belonging to one of
   the given ranges. Each `range` is a string `xy` of length 2, representing
   all characters with code between the codes of `x` and `y` (both
   inclusive). As an example, the pattern `lpeg.R('09')` matches any digit,
   and `lpeg.R('az', 'AZ')` matches any ASCII letter.

   Example: >lua
       local pattern = lpeg.R('az') ^ 1 * -1
       assert(pattern:match('hello') == 6)
<

   Parameters: ~
     • {...}  (`string`)

   Return: ~
       (`vim.lpeg.Pattern`)

vim.lpeg.S({string})                                            *vim.lpeg.S()*
   Returns a pattern that matches any single character that appears in the
   given string (the `S` stands for Set). As an example, the pattern
   `lpeg.S('+-*/')` matches any arithmetic operator. Note that, if `s` is a
   character (that is, a string of length 1), then `lpeg.P(s)` is equivalent
   to `lpeg.S(s)` which is equivalent to `lpeg.R(s..s)`. Note also that both
   `lpeg.S('')` and `lpeg.R()` are patterns that always fail.

   Parameters: ~
     • {string}  (`string`)

   Return: ~
       (`vim.lpeg.Pattern`)

vim.lpeg.setmaxstack({max})                           *vim.lpeg.setmaxstack()*
   Sets a limit for the size of the backtrack stack used by LPeg to track
   calls and choices. The default limit is `400`. Most well-written patterns
   need little backtrack levels and therefore you seldom need to change this
   limit; before changing it you should try to rewrite your pattern to avoid
   the need for extra space. Nevertheless, a few useful patterns may
   overflow. Also, with recursive grammars, subjects with deep recursion may
   also need larger limits.

   Parameters: ~
     • {max}  (`integer`)

vim.lpeg.type({value})                                       *vim.lpeg.type()*
   Returns the string `"pattern"` if the given value is a pattern, otherwise
   `nil`.

   Parameters: ~
     • {value}  (`vim.lpeg.Pattern|string|integer|boolean|table|function`)

   Return: ~
       (`"pattern"?`)

vim.lpeg.V({v})                                                 *vim.lpeg.V()*
   Creates a non-terminal (a variable) for a grammar. This operation creates
   a non-terminal (a variable) for a grammar. The created non-terminal refers
   to the rule indexed by `v` in the enclosing grammar.

   Example: >lua
       local b = lpeg.P({'(' * ((1 - lpeg.S '()') + lpeg.V(1)) ^ 0 * ')'})
       assert(b:match('((string))') == 11)
       assert(b:match('(') == nil)
<

   Parameters: ~
     • {v}  (`boolean|string|number|function|table|thread|userdata|lightuserdata`)

   Return: ~
       (`vim.lpeg.Pattern`)

vim.lpeg.version()                                        *vim.lpeg.version()*
   Returns a string with the running version of LPeg.

   Return: ~
       (`string`)

Lua module: vim.net                                                  *vim.net*

vim.net.request({url}, {opts}, {on_response})              *vim.net.request()*
   Makes an HTTP GET request to the given URL (asynchronous).

   This function operates in one mode:
   • Asynchronous (non-blocking): Returns immediately and passes the response
     object to the provided `on_response` handler on completion.

   Parameters: ~
     • {url}          (`string`) The URL for the request.
     • {opts}         (`table?`) Optional parameters:
                      • `verbose` (boolean|nil): Enables verbose output.
                      • `retry` (integer|nil): Number of retries on transient
                        failures (default: 3).

                        response body to. If set, the `body` value in the
                        Response Object will be `true` instead of the
                        response body.
     • {on_response}  (`fun(err?: string, response?: { body: string|boolean })`)
                      Callback invoked on request completion. The `body`
                      field in the response object contains the raw response
                      data (text or binary). Called with (err, nil) on
                      failure, or (nil, { body = string|boolean }) on
                      success.

EXPERIMENTAL: This API may change in the future. Its semantics are not yet
finalized. Subscribe to https://github.com/neovim/neovim/issues/25509 to stay
updated or contribute to its development.

Provides operations to compare, calculate, and convert positions represented
by |vim.Pos| objects.


*vim.Pos*
   Represents a well-defined position.

   A |vim.Pos| object contains the {row} and {col} coordinates of a position.
   To create a new |vim.Pos| object, call `vim.pos()`.

   Example: >lua
       local pos1 = vim.pos(3, 5)
       local pos2 = vim.pos(4, 0)

       -- Operators are overloaded for comparing two `vim.Pos` objects.
       if pos1 < pos2 then
         print("pos1 comes before pos2")
       end

       if pos1 ~= pos2 then
         print("pos1 and pos2 are different positions")
       end
<

   It may include optional fields that enable additional capabilities, such
   as format conversions.

   Fields: ~
     • {row}         (`integer`) 0-based byte index.
     • {col}         (`integer`) 0-based byte index.
     • {buf}?        (`integer`) Optional buffer handle.

                     When specified, it indicates that this position belongs
                     to a specific buffer. This field is required when
                     performing position conversions.

Lua module: vim.range                                              *vim.range*

EXPERIMENTAL: This API may change in the future. Its semantics are not yet
finalized. Subscribe to https://github.com/neovim/neovim/issues/25509 to stay
updated or contribute to its development.

Provides operations to compare, calculate, and convert ranges represented by
|vim.Range| objects.


*vim.Range*
   Represents a well-defined range.

   A |vim.Range| object contains a {start} and a {end_} position(see
   |vim.Pos|). Note that the {end_} position is exclusive. To create a new
   |vim.Range| object, call `vim.range()`.

   Example: >lua
       local pos1 = vim.pos(3, 5)
       local pos2 = vim.pos(4, 0)

       -- Create a range from two positions.
       local range1 = vim.range(pos1, pos2)
       -- Or create a range from four integers representing start and end positions.
       local range2 = vim.range(3, 5, 4, 0)

       -- Because `vim.Range` is end exclusive, `range1` and `range2` both represent
       -- a range starting at the row 3, column 5 and ending at where the row 3 ends.

       -- Operators are overloaded for comparing two `vim.Pos` objects.
       if range1 == range2 then
         print("range1 and range2 are the same range")
       end
<

   It may include optional fields that enable additional capabilities, such
   as format conversions. Note that the {start} and {end_} positions need to
   have the same optional fields.

   Fields: ~
     • {start}      (`vim.Pos`) Start position.
     • {end_}       (`vim.Pos`) End position, exclusive.

Lua module: vim.re                                                    *vim.re*

The `vim.re` module provides a conventional regex-like syntax for pattern
usage within LPeg |vim.lpeg|. (Unrelated to |vim.regex| which provides Vim
|regexp| from Lua.)

See https://www.inf.puc-rio.br/~roberto/lpeg/re.html for the original
documentation including regex syntax and examples.


vim.re.compile({string}, {defs})                            *vim.re.compile()*
   Compiles the given {string} and returns an equivalent LPeg pattern. The
   given string may define either an expression or a grammar. The optional
   {defs} table provides extra Lua values to be used by the pattern.

   Parameters: ~
     • {string}  (`string`)
     • {defs}    (`table?`)

   Return: ~
       (`vim.lpeg.Pattern`)

vim.re.find({subject}, {pattern}, {init})                      *vim.re.find()*
   Searches the given {pattern} in the given {subject}. If it finds a match,
   returns the index where this occurrence starts and the index where it
   ends. Otherwise, returns nil.

   An optional numeric argument {init} makes the search starts at that
   position in the subject string. As usual in Lua libraries, a negative
   value counts from the end.

   Parameters: ~
     • {subject}  (`string`)
     • {pattern}  (`vim.lpeg.Pattern|string`)
     • {init}     (`integer?`)

   Return (multiple): ~
       (`integer?`) the index where the occurrence starts, nil if no match
       (`integer?`) the index where the occurrence ends, nil if no match

vim.re.gsub({subject}, {pattern}, {replacement})               *vim.re.gsub()*
   Does a global substitution, replacing all occurrences of {pattern} in the
   given {subject} by {replacement}.

   Parameters: ~
     • {subject}      (`string`)
     • {pattern}      (`vim.lpeg.Pattern|string`)
     • {replacement}  (`string`)

   Return: ~
       (`string`)

vim.re.match({subject}, {pattern}, {init})                    *vim.re.match()*
   Matches the given {pattern} against the given {subject}, returning all
   captures.

   Parameters: ~
     • {subject}  (`string`)
     • {pattern}  (`vim.lpeg.Pattern|string`)
     • {init}     (`integer?`)

   Return: ~
       (`integer|vim.lpeg.Capture?`)

   See also: ~
     • vim.lpeg.match()

vim.re.updatelocale()                                  *vim.re.updatelocale()*
   Updates the pre-defined character classes to the current locale.


==============================================================================
Lua module: vim.regex                                              *vim.regex*

Vim regexes can be used directly from Lua. Currently they only allow matching
within a single line.


                                                         *regex:match_line()*
regex:match_line({bufnr}, {line_idx}, {start}, {end_})
   Matches line at `line_idx` (zero-based) in buffer `bufnr`. Match is
   restricted to byte index range `start` and `end_` if given, otherwise see
   |regex:match_str()|. Returned byte indices are relative to `start` if
   given.

   Parameters: ~
     • {bufnr}     (`integer`)
     • {line_idx}  (`integer`)
     • {start}     (`integer?`)
     • {end_}      (`integer?`)

   Return (multiple): ~
       (`integer?`) match start (byte index) relative to `start`, or `nil` if
       no match
       (`integer?`) match end (byte index) relative to `start`, or `nil` if
       no match

regex:match_str({str})                                     *regex:match_str()*
   Matches string `str` against this regex. To match the string precisely,
   surround the regex with "^" and "$". Returns the byte indices for the
   start and end of the match, or `nil` if there is no match. Because any
   integer is "truthy", `regex:match_str()` can be directly used as a
   condition in an if-statement.

   Parameters: ~
     • {str}  (`string`)

   Return (multiple): ~
       (`integer?`) match start (byte index), or `nil` if no match
       (`integer?`) match end (byte index), or `nil` if no match

vim.regex({re})                                                  *vim.regex()*
   Parses the Vim regex `re` and returns a regex object. Regexes are "magic"
   and case-sensitive by default, regardless of 'magic' and 'ignorecase'.
   They can be controlled with flags, see |/magic| and |/ignorecase|.

   Parameters: ~
     • {re}  (`string`)

   Return: ~
       (`vim.regex`)

   If {path} is a file: attempt to read the file, prompting the user if the
   file should be trusted.

   If {path} is a directory: return true if the directory is trusted
   (non-recursive), prompting the user as necessary.

   The user's choice is persisted in a trust database at
   $XDG_STATE_HOME/nvim/trust.

   Attributes: ~
       Since: 0.9.0

   Parameters: ~
     • {path}  (`string`) Path to a file or directory to read.

   Return: ~
       (`boolean|string?`) If {path} is not trusted or does not exist,

                     |SystemObj:write()|.

SystemObj:is_closing()                                *SystemObj:is_closing()*
   Checks if the process handle is closing or already closed.

   This method returns `true` if the underlying process handle is either
   `nil` or is in the process of closing. It is useful for determining
   whether it is safe to perform operations on the process handle.

   Return: ~
       (`boolean`)

SystemObj:kill({signal})                                    *SystemObj:kill()*
   Sends a signal to the process.

   The signal can be specified as an integer or as a string.

   Example: >lua
       local obj = vim.system({'sleep', '10'})
       obj:kill('sigterm') -- sends SIGTERM to the process
<

   Parameters: ~
     • {signal}  (`integer|string`) Signal to send to the process. See
                 |luv-constants|.

SystemObj:wait({timeout})                                   *SystemObj:wait()*
   Waits for the process to complete or until the specified timeout elapses.

   This method blocks execution until the associated process has exited or
   the optional `timeout` (in milliseconds) has been reached. If the process
   does not exit before the timeout, it is forcefully terminated with SIGKILL
   (signal 9), and the exit code is set to 124.

   If no `timeout` is provided, the method will wait indefinitely (or use the
   timeout specified in the options when the process was started).

   Example: >lua
       local obj = vim.system({'echo', 'hello'}, { text = true })
       local result = obj:wait(1000) -- waits up to 1000ms
       print(result.code, result.signal, result.stdout, result.stderr)
<

   Parameters: ~
     • {timeout}  (`integer?`)

   Return: ~
       (`vim.SystemCompleted`) See |vim.SystemCompleted|.

SystemObj:write({data})                                    *SystemObj:write()*
   Writes data to the stdin of the process or closes stdin.

   If `data` is a list of strings, each string is written followed by a
   newline.

   If `data` is a string, it is written as-is.

   If `data` is `nil`, the write side of the stream is shut down and the pipe
   is closed.

   Example: >lua
       local obj = vim.system({'cat'}, { stdin = true })
       obj:write({'hello', 'world'}) -- writes 'hello\nworld\n' to stdin
       obj:write(nil) -- closes stdin
<

   Parameters: ~
     • {data}  (`string[]|string?`)

vim.system({cmd}, {opts}, {on_exit})                            *vim.system()*
   Runs a system command or throws an error if {cmd} cannot be run.

   The command runs directly (not in 'shell') so shell builtins such as
   "echo" in cmd.exe, cmdlets in powershell, or "help" in bash, will not work
   unless you actually invoke a shell: `vim.system({'bash', '-c', 'help'})`.

   Examples: >lua
       local on_exit = function(obj)
         print(obj.code)
         print(obj.signal)
         print(obj.stdout)
         print(obj.stderr)
       end

       -- Runs asynchronously:
       vim.system({'echo', 'hello'}, { text = true }, on_exit)

       -- Runs synchronously:
       local obj = vim.system({'echo', 'hello'}, { text = true }):wait()
       -- { code = 0, signal = 0, stdout = 'hello\n', stderr = '' }
<

   See |uv.spawn()| for more details. Note: unlike |uv.spawn()|, vim.system
   throws an error if {cmd} cannot be run.

   Parameters: ~
     • {cmd}      (`string[]`) Command to execute
     • {opts}     (`table?`) A table with the following fields:
                  • {cwd}? (`string`) Set the current working directory for
                    the sub-process.
                  • {env}? (`table<string,string|number>`) Set environment
                    variables for the new process. Inherits the current
                    environment with `NVIM` set to |v:servername|.
                  • {clear_env}? (`boolean`) `env` defines the job
                    environment exactly, instead of merging current
                    environment. Note: if `env` is `nil`, the current
                    environment is used but without `NVIM` set.
                  • {stdin}? (`string|string[]|true`) If `true`, then a pipe
                    to stdin is opened and can be written to via the
                    `write()` method to SystemObj. If `string` or `string[]`
                    then will be written to stdin and closed.
                  • {stdout}? (`fun(err:string?, data: string?)|boolean`,
                    default: `true`) Handle output from stdout.
                  • {stderr}? (`fun(err:string?, data: string?)|boolean`,
                    default: `true`) Handle output from stderr.
                  • {text}? (`boolean`) Handle stdout and stderr as text.
                    Normalizes line endings by replacing `\r\n` with `\n`.
                  • {timeout}? (`integer`) Run the command with a time limit
                    in ms. Upon timeout the process is sent the TERM signal
                    (15) and the exit code is set to 124.
                  • {detach}? (`boolean`) Spawn the child process in a
                    detached state - this will make it a process group
                    leader, and will effectively enable the child to keep
                    running after the parent exits. Note that the child
                    process will still keep the parent's event loop alive
                    unless the parent process calls |uv.unref()| on the
                    child's process handle.
     • {on_exit}  (`fun(out: vim.SystemCompleted)?`) Called when subprocess
                  exits. When provided, the command runs asynchronously. See
                  return of SystemObj:wait().

   Overloads: ~
     • `fun(cmd: string[], on_exit: fun(out: vim.SystemCompleted)): vim.SystemObj`

   Return: ~
       (`vim.SystemObj`) See |vim.SystemObj|.

vim.text.hexdecode({enc})                               *vim.text.hexdecode()*
   Hex decode a string.

   Parameters: ~
     • {enc}  (`string`) String to decode

   Return (multiple): ~
       (`string?`) Decoded string
       (`string?`) Error message, if any

vim.text.hexencode({str})                               *vim.text.hexencode()*
   Hex encode a string.

   Parameters: ~

   Return: ~
       (`string`) Hex encoded string

vim.text.indent({size}, {text}, {opts})                    *vim.text.indent()*
   Sets the indent (i.e. the common leading whitespace) of non-empty lines in
   `text` to `size` spaces/tabs.

   Indent is calculated by number of consecutive indent chars.
   • The first indented, non-empty line decides the indent char (space/tab):
     • `SPC SPC TAB …` = two-space indent.
     • `TAB SPC …` = one-tab indent.
   • Set `opts.expandtab` to treat tabs as spaces.

   To "dedent" (remove the common indent), pass `size=0`: >lua
       vim.print(vim.text.indent(0, ' a\n  b\n'))
<

   To adjust relative-to an existing indent, call indent() twice: >lua
       local indented, old_indent = vim.text.indent(0, ' a\n b\n')
       indented = vim.text.indent(old_indent + 2, indented)
       vim.print(indented)
<

   To ignore the final, blank line when calculating the indent, use gsub()
   before calling indent(): >lua
       local text = '  a\n  b\n '
       vim.print(vim.text.indent(0, (text:gsub('\n[\t ]+\n?$', '\n'))))
<

   Parameters: ~
     • {size}  (`integer`) Number of spaces.
     • {text}  (`string`) Text to indent.
     • {opts}  (`{ expandtab?: integer }?`)

   Return (multiple): ~
       (`string`) Indented text.
       (`integer`) Indent size before modification.

       -- Asynchronous.
       vim.ui.open("https://neovim.io/")
       vim.ui.open("~/path/to/file")
       -- Use the "osurl" command to handle the path or URL.
       vim.ui.open("gh#neovim/neovim!29490", { cmd = { 'osurl' } })
       -- Synchronous (wait until the process exits).
       local cmd, err = vim.ui.open("$VIMRUNTIME")
       if cmd then
         cmd:wait()
       end

     • |vim.system()|

vim.ui.select({items}, {opts}, {on_choice})                  *vim.ui.select()*
   Prompts the user to pick from a list of items, allowing arbitrary
   (potentially asynchronous) work until `on_choice`.

   Example: >lua
       vim.ui.select({ 'tabs', 'spaces' }, {
           prompt = 'Select tabs or spaces:',
           format_item = function(item)
               return "I'd like to choose " .. item
           end,
       }, function(choice)
           if choice == 'spaces' then
               vim.o.expandtab = true
           else
               vim.o.expandtab = false
           end
       end)
<

   Parameters: ~
     • {items}      (`any[]`) Arbitrary items
     • {opts}       (`table`) Additional options
                    • {prompt}? (`string`) Text of the prompt. Defaults to

                    • {format_item}? (`fun(item: any):string`) Function to
                      format an individual item from `items`. Defaults to
                      `tostring`.
                    • {kind}? (`string`) Arbitrary hint string indicating the
                      item shape. Plugins reimplementing `vim.ui.select` may
                      wish to use this to infer the structure or semantics of
                      `items`, or the context in which select() was called.
     • {on_choice}  (`fun(item: T?, idx: integer?)`) Called once the user
                    made a choice. `idx` is the 1-based index of `item`
                    within `items`. `nil` if the user aborted the dialog.

==============================================================================
Lua module: vim.version                                          *vim.version*

The `vim.version` module provides functions for comparing versions and ranges
conforming to the https://semver.org spec. Plugins, and plugin managers, can
use this to check available tools and dependencies on the current system.

Example: >lua
   local v = vim.version.parse(vim.system({'tmux', '-V'}):wait().stdout, {strict=false})
   if vim.version.gt(v, {3, 2, 0}) then
     -- ...
   end
<

*vim.version()* returns the version of the current Nvim process.

VERSION RANGE SPEC                                             *version-range*

A version "range spec" defines a semantic version range which can be tested
against a version, using |vim.version.range()|.

Supported range specs are shown in the following table. Note: suffixed
versions (1.2.3-rc1) are not matched. >
   1.2.3             is 1.2.3
   =1.2.3            is 1.2.3
   >1.2.3            greater than 1.2.3
   <1.2.3            before 1.2.3
   >=1.2.3           at least 1.2.3

*vim.VersionRange*

   Fields: ~
     • {from}  (`vim.Version`)
     • {to}?   (`vim.Version`)
     • {has}   (`fun(self: vim.VersionRange, version: string|vim.Version): boolean`)
               See |VersionRange:has()|.


VersionRange:has({version})                               *VersionRange:has()*
   Check if a version is in the range (inclusive `from`, exclusive `to`).

   Example: >lua
       local r = vim.version.range('1.0.0 - 2.0.0')
       print(r:has('1.9.9'))       -- true
       print(r:has('2.0.0'))       -- false
       print(r:has(vim.version())) -- check against current Nvim version
<

   Or use cmp(), le(), lt(), ge(), gt(), and/or eq() to compare a version
   against `.to` and `.from` directly: >lua
       local r = vim.version.range('1.0.0 - 2.0.0') -- >=1.0, <2.0
       print(vim.version.ge({1,0,3}, r.from) and vim.version.lt({1,0,3}, r.to))

vim.version.cmp({v1}, {v2})                                *vim.version.cmp()*
   Parses and compares two version objects (the result of
   |vim.version.parse()|, or specified literally as a `{major, minor, patch}`
   tuple, e.g. `{1, 0, 3}`).

   Example: >lua
       if vim.version.cmp({1,0,3}, {0,2,1}) == 0 then
         -- ...
       end
       local v1 = vim.version.parse('1.0.3-pre')
       local v2 = vim.version.parse('0.2.1')
       if vim.version.cmp(v1, v2) == 0 then
         -- ...
       end

UI2                                                                      *ui2*

WARNING: This is an experimental interface intended to replace the message
grid in the TUI.

To enable the experimental UI (default opts shown): >lua
   require('vim._core.ui2').enable({
    enable = true, -- Whether to enable or disable the UI.
    msg = { -- Options related to the message module.
      ---@type 'cmd'|'msg' Default message target, either in the
      ---cmdline or in a separate ephemeral message window.
      ---@type string|table<string, 'cmd'|'msg'|'pager'> Default message target
      or table mapping |ui-messages| kinds to a target.
      targets = 'cmd',
      timeout = 4000, -- Time a message is visible in the message window.
    },
   })
<

There are four separate window types used by this interface:
• "cmd": The cmdline window; also used for 'showcmd', 'showmode', 'ruler', and
 messages if 'cmdheight' > 0.
• "msg": The message window; used for messages when 'cmdheight' == 0.
• "pager": The pager window; used for |:messages| and certain messages that
 should be shown in full.
• "dialog": The dialog window; used for prompt messages that expect user
 input.

These four windows are assigned the "cmd", "msg", "pager" and "dialog"
'filetype' respectively. Use a |FileType| autocommand to configure any local
options for these windows and their respective buffers.

Rather than a |hit-enter-prompt|, messages shown in the cmdline area that do
not fit are appended with a `[+x]` "spill" indicator, where `x` indicates the
spilled lines. To see the full message, the |g<| command can be used.
