+---    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
+---
+---</pre>
+
+--- 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|).
+function vim.in_fast_event() end
+
+--- Creates a special empty table (marked with a metatable), which Nvim 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.
+function vim.empty_dict() end

+function vim.stricmp(a, b) end
+
+--- Convert UTF-32 or UTF-16 {index} to byte index. If {use_utf16} is not
+--- supplied, it defaults to false (use UTF-32). Returns the byte index.
+---
+--- Invalid UTF-8 and NUL is treated like by |vim.str_byteindex()|.
+--- An {index} in the middle of a UTF-16 sequence is rounded upwards to
+--- the end of that sequence.

+
+--- Convert byte index to UTF-32 and UTF-16 indices. If {index} is not
+--- supplied, the length of the string is used. All indices are zero-based.
+---
+--- Embedded NUL bytes are treated as terminating the string. 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.

+--- @return integer UTF-32 index
+--- @return integer UTF-16 index
+function vim.str_utfindex(str, index) end
+
+--- 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".
+---
+--- @param str string Text to convert
+--- @param from number Encoding of {str}
+--- @param to number Target encoding
+--- @param opts? table<string, any>
+--- @return string|nil Converted string if conversion succeeds, `nil` otherwise.
+function vim.iconv(str, from, to, opts) end

+--- Schedules {callback} to be invoked soon by the main event-loop. Useful
+--- to avoid |textlock| or other temporary restrictions.
+--- @param callback fun()
+function vim.schedule(callback) end
+
+--- Wait for {time} in milliseconds until {callback} returns `true`.
+---
+--- Executes {callback} immediately and at approximately {interval}
+--- milliseconds (default 200). Nvim still processes other events during
+--- this time.
+---
+--- Examples:
+--- <pre>lua
+---
+--- ---
+--- -- Wait for 100 ms, allowing other events to process
+--- vim.wait(100, function() end)
+---
+--- ---
+--- -- Wait for 100 ms or until global variable set.
+--- vim.wait(100, function() return vim.g.waiting_for_var end)
+---
+--- ---
+--- -- Wait for 1 second or until global variable set, checking every ~500 ms
+--- vim.wait(1000, function() return vim.g.waiting_for_var end, 500)
+---
+--- ---
+--- -- Schedule a function to set a value in 100ms
+--- vim.defer_fn(function() vim.g.timer_result = true end, 100)
+---
+--- -- Would wait ten seconds if results blocked. Actually only waits  100 ms
+--- if vim.wait(10000, function() return vim.g.timer_result end) then
+---   print('Only waiting a little bit of time!')
+--- end
+--- </pre>
+---
+--- @param time integer Number of milliseconds to wait
+--- @param callback? fun(): boolean Optional callback. Waits until {callback} returns true
+--- @param interval? integer (Approximate) number of milliseconds to wait between polls
+--- @param fast_only? boolean If true, only |api-fast| events will be processed.
+---                           If called from while in an |api-fast| event, will
+---                           automatically be set to `true`.
+--- @return boolean, nil|-1|-2
+---     - If {callback} returns `true` during the {time}: `true, nil`
+---     - If {callback} never returns `true` during the {time}: `false, -1`
+---     - If {callback} is interrupted during the {time}: `false, -2`
+---     - If {callback} errors, the error is raised.
+function vim.wait(time, callback, interval, fast_only) end
+
+--- Attach to ui events, similar to |nvim_ui_attach()| but receive events
+--- as Lua callback. Can be used to implement screen elements like
+--- popupmenu or message handling in Lua.
+---
+--- {options} should be a dictionary-like table, where `ext_...` options should
+--- be set to true to receive events for the respective external element.
+---
+--- {callback} receives event name plus additional parameters. See |ui-popupmenu|
+--- and the sections below for event format for respective events.
+---
+--- 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):
+--- <pre>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)
+--- </pre>
+--- @param ns integer
+--- @param options table<string, any>
+--- @param callback fun()
+function vim.ui_attach(ns, options, callback) end
+
+--- Detach a callback previously attached with |vim.ui_attach()| for the
+--- given namespace {ns}.
+--- @param ns integer
+function vim.ui_detach(ns) end
