--- Adds a highlight to buffer.
---
--- Useful for plugins that dynamically generate highlights to a buffer (like
--- a semantic highlighter or linter). The function adds a single highlight to
--- a buffer. Unlike `matchaddpos()` highlights follow changes to line
--- numbering (as lines are inserted/removed above the highlighted line), like
--- signs and marks do.
---
--- Namespaces are used for batch deletion/updating of a set of highlights. To
--- create a namespace, use `nvim_create_namespace()` which returns a
--- namespace id. Pass it in to this function as `ns_id` to add highlights to
--- the namespace. All highlights in the same namespace can then be cleared
--- with single call to `nvim_buf_clear_namespace()`. If the highlight never
--- will be deleted by an API call, pass `ns_id = -1`.
---
--- As a shorthand, `ns_id = 0` can be used to create a new namespace for the
--- highlight, the allocated id is then returned. If `hl_group` is the empty
--- string no highlight is added, but a new `ns_id` is still returned. This is
--- supported for backwards compatibility, new code should use
--- `nvim_create_namespace()` to create a new empty namespace.
---
--- @param buffer integer Buffer handle, or 0 for current buffer
--- @param ns_id integer namespace to use or -1 for ungrouped highlight
--- @param hl_group string Name of the highlight group to use
--- @param line integer Line to highlight (zero-indexed)
--- @param col_start integer Start of (byte-indexed) column range to highlight
--- @param col_end integer End of (byte-indexed) column range to highlight, or -1 to
---                highlight to end of line
--- @return integer
function vim.api.nvim_buf_add_highlight(buffer, ns_id, hl_group, line, col_start, col_end) end

--- Activates buffer-update events on a channel, or as Lua callbacks.

---     vim.api.nvim_buf_attach(0, false, {

--- Gets `extmarks` in "traversal order" from a `charwise` region defined by
--- buffer positions (inclusive, 0-indexed `api-indexing`).
---
--- Region can be given as (row,col) tuples, or valid extmark ids (whose
--- positions define the bounds). 0 and -1 are understood as (0,0) and (-1,-1)
--- respectively, thus the following are equivalent:
---
--- ```lua
---     vim.api.nvim_buf_get_extmarks(0, my_ns, 0, -1, {})
---     vim.api.nvim_buf_get_extmarks(0, my_ns, {0,0}, {-1,-1}, {})
--- ```
---
--- If `end` is less than `start`, traversal works backwards. (Useful with
--- `limit`, to get the first marks prior to a given position.)
---
--- Note: when using extmark ranges (marks with a end_row/end_col position)
--- the `overlap` option might be useful. Otherwise only the start position of
--- an extmark will be considered.
---
--- Note: legacy signs placed through the `:sign` commands are implemented as
--- extmarks and will show up here. Their details array will contain a
--- `sign_name` field.
---
--- Example:
---
--- ```lua
---     local api = vim.api
---     local pos = api.nvim_win_get_cursor(0)
---     local ns  = api.nvim_create_namespace('my-plugin')

--- Creates or updates an `extmark`.

---                 for "inline" virt_text.
---             • virt_lines : virtual lines to add next to this mark This
---               should be an array over lines, where each line in turn is an
---               array over `[text, highlight]` tuples. In general, buffer
---               and window options do not affect the display of the text. In
---               particular 'wrap' and 'linebreak' options do not take
---               effect, so the number of extra screen lines will always
---               match the size of the array. However the 'tabstop' buffer
---               option is still used for hard tabs. By default lines are
---               placed below the buffer line containing the mark.
---             • virt_lines_above: place virtual lines above instead.
---             • virt_lines_leftcol: Place extmarks in the leftmost column of
---               the window, bypassing sign and number columns.
---             • ephemeral : for use with `nvim_set_decoration_provider()`
---               callbacks. The mark will only be used for the current redraw
---               cycle, and not be permantently stored in the buffer.
---             • right_gravity : boolean that indicates the direction the
---               extmark will be shifted in when new text is inserted (true
---               for right, false for left). Defaults to true.
---             • end_right_gravity : boolean that indicates the direction the
---               extmark end position (if it exists) will be shifted in when
---               new text is inserted (true for right, false for left).
---               Defaults to false.
---             • undo_restore : Restore the exact position of the mark if
---               text around the mark was deleted and then restored by undo.
---               Defaults to true.
---             • invalidate : boolean that indicates whether to hide the
---               extmark if the entirety of its range is deleted. For hidden
---               marks, an "invalid" key is added to the "details" array of
---               `nvim_buf_get_extmarks()` and family. If "undo_restore" is
---               false, the extmark is deleted instead.
---             • priority: a priority value for the highlight group, sign
---               attribute or virtual text. For virtual text, item with
---               highest priority is drawn last. For example treesitter
---               highlighting uses a value of 100.
---             • strict: boolean that indicates extmark should not be placed
---               if the line or column value is past the end of the buffer or
---               end of the line respectively. Defaults to true.
---             • sign_text: string of length 1-2 used to display in the sign
---               column.
---             • sign_hl_group: name of the highlight group used to highlight
---               the sign column text.
---             • number_hl_group: name of the highlight group used to
---               highlight the number column.
---             • line_hl_group: name of the highlight group used to highlight
---               the whole line.
---             • cursorline_hl_group: name of the highlight group used to
---               highlight the sign column text when the cursor is on the
---               same line as the mark and 'cursorline' is enabled.
---             • conceal: string which should be either empty or a single
---               character. Enable concealing similar to `:syn-conceal`. When
---               a character is supplied it is used as `:syn-cchar`.
---               "hl_group" is used as highlight for the cchar if provided,
---               otherwise it defaults to `hl-Conceal`.
---             • spell: boolean indicating that spell checking should be
---               performed within this extmark
---             • ui_watched: boolean that indicates the mark should be drawn
---               by a UI. When set, the UI will receive win_extmark events.
---               Note: the mark is positioned by virt_text attributes. Can be
---               used together with virt_text.
---             • url: A URL to associate with this extmark. In the TUI, the
---               OSC 8 control sequence is used to generate a clickable
---               hyperlink to this URL.

--- Executes an Ex command.
---
--- Unlike `nvim_command()` this command takes a structured Dictionary instead
--- of a String. This allows for easier construction and manipulation of an Ex
--- command. This also allows for things such as having spaces inside a

--- expand filenames, etc. Command arguments may also be Number, Boolean or
--- String.
---
--- The first argument may also be used instead of count for commands that
--- support it in order to make their usage simpler with `vim.cmd()`. For
--- example, instead of `vim.cmd.bdelete{ count = 2 }`, you may do
--- `vim.cmd.bdelete(2)`.
---

--- Creates an `autocommand` event handler, defined by `callback` (Lua
--- function or Vimscript function name string) or `command` (Ex command

--- ```lua
---     vim.api.nvim_create_autocmd({"BufEnter", "BufWinEnter"}, {
---       pattern = {"*.c", "*.h"},
---       command = "echo 'Entering a C or C++ file'",

--- Opens a new split window, or a floating window if `relative` is specified,
--- or an external window (managed by the UI) if `external` is specified.
---
--- Floats are windows that are drawn above the split layout, at some anchor
--- position in some other window. Floats can be drawn internally or by
--- external GUI with the `ui-multigrid` extension. External windows are only
--- supported with multigrid GUIs, and are displayed as separate top-level
--- windows.
---
--- For a general overview of floats, see `api-floatwin`.
---
--- The `width` and `height` of the new window must be specified when opening
--- a floating window, but are optional for normal windows.
---
--- If `relative` and `external` are omitted, a normal "split" window is
--- created. The `win` property determines which window will be split. If no
--- `win` is provided or `win == 0`, a window will be created adjacent to the
--- current window. If -1 is provided, a top-level split will be created.
--- `vertical` and `split` are only valid for normal windows, and are used to
--- control split direction. For `vertical`, the exact direction is determined
--- by `'splitright'` and `'splitbelow'`. Split windows cannot have
--- `bufpos`/`row`/`col`/`border`/`title`/`footer` properties.
---
--- With relative=editor (row=0,col=0) refers to the top-left corner of the
--- screen-grid and (row=Lines-1,col=Columns-1) refers to the bottom-right
--- corner. Fractional values are allowed, but the builtin implementation
--- (used by non-multigrid UIs) will always round down to nearest integer.
---
--- Out-of-bounds values, and configurations that make the float not fit
--- inside the main editor, are allowed. The builtin implementation truncates
--- values so floats are fully within the main screen grid. External GUIs
--- could let floats hover outside of the main window like a tooltip, but this
--- should not be used to specify arbitrary WM screen positions.

---
--- ```lua
---     vim.api.nvim_open_win(0, false,

---               • width: Window width (in character cells). Minimum of 1.
---               • height: Window height (in character cells). Minimum of 1.
---               • bufpos: Places float relative to buffer text (only when
---                 relative="win"). Takes a tuple of zero-indexed
---                 `[line, column]`. `row` and `col` if given are applied
---                 relative to this position, else they default to:
---                 • `row=1` and `col=0` if `anchor` is "NW" or "NE"
---                 • `row=0` and `col=0` if `anchor` is "SW" or "SE" (thus
---                   like a tooltip near the buffer text).
---               • row: Row position in units of "screen cell height", may be
---                 fractional.
---               • col: Column position in units of "screen cell width", may
---                 be fractional.
---               • focusable: Enable focus by user actions (wincmds, mouse
---                 events). Defaults to true. Non-focusable windows can be
---                 entered by `nvim_set_current_win()`.
---               • external: GUI should display the window as an external
---                 top-level window. Currently accepts no other positioning
---                 configuration together with this.
---               • zindex: Stacking order. floats with higher `zindex` go on
---                 top on floats with lower indices. Must be larger than
---                 zero. The following screen elements have hard-coded
---                 z-indices:
---                 • 100: insert completion popupmenu
---                 • 200: message scrollback
---                 • 250: cmdline completion popupmenu (when
---                   wildoptions+=pum) The default value for floats are 50.
---                   In general, values below 100 are recommended, unless
---                   there is a good reason to overshadow builtin elements.
---               • style: (optional) Configure the appearance of the window.
---                 Currently only supports one value:
---                 • "minimal" Nvim will display the window with many UI
---                   options disabled. This is useful when displaying a
---                   temporary float where the text should not be edited.
---                   Disables 'number', 'relativenumber', 'cursorline',
---                   'cursorcolumn', 'foldcolumn', 'spell' and 'list'
---                   options. 'signcolumn' is changed to `auto` and
---                   'colorcolumn' is cleared. 'statuscolumn' is changed to
---                   empty. The end-of-buffer region is hidden by setting
---                   `eob` flag of 'fillchars' to a space char, and clearing
---                   the `hl-EndOfBuffer` region in 'winhighlight'.
---               • border: Style of (optional) window border. This can either
---                 be a string or an array. The string values are
---                 • "none": No border (default).
---                 • "single": A single line box.
---                 • "double": A double line box.
---                 • "rounded": Like "single", but with rounded corners
---                   ("╭" etc.).
---                 • "solid": Adds padding by a single whitespace cell.
---                 • "shadow": A drop shadow effect by blending with the
---                   background.
---                 • If it is an array, it should have a length of eight or
---                   any divisor of eight. The array will specify the eight
---                   chars building up the border in a clockwise fashion
---                   starting with the top-left corner. As an example, the
---                   double box style could be specified as:
--- ```
---                   [ "╔", "═" ,"╗", "║", "╝", "═", "╚", "║" ].
--- ```
---
---                   If the number of chars are less than eight, they will be
---                   repeated. Thus an ASCII border could be specified as
--- ```
---                   [ "/", "-", \"\\\\\", "|" ],
--- ```
---
---                   or all chars the same as
--- ```
---                   [ "x" ].
--- ```
---
---                 An empty string can be used to turn off a specific border,
---                 for instance,
--- ```
---                  [ "", "", "", ">", "", "", "", "<" ]
--- ```
---
---                 will only make vertical borders but not horizontal ones.
---                 By default, `FloatBorder` highlight is used, which links
---                 to `WinSeparator` when not defined. It could also be
---                 specified by character:
--- ```
---                  [ ["+", "MyCorner"], ["x", "MyBorder"] ].
--- ```
---
---               • title: Title (optional) in window border, string or list.
---                 List should consist of `[text, highlight]` tuples. If
---                 string, the default highlight group is `FloatTitle`.
---               • title_pos: Title position. Must be set with `title`
---                 option. Value can be one of "left", "center", or "right".
---                 Default is `"left"`.
---               • footer: Footer (optional) in window border, string or
---                 list. List should consist of `[text, highlight]` tuples.
---                 If string, the default highlight group is `FloatFooter`.
---               • footer_pos: Footer position. Must be set with `footer`
---                 option. Value can be one of "left", "center", or "right".
---                 Default is `"left"`.
---               • noautocmd: If true then all autocommands are blocked for
---                 the duration of the call.
---               • fixed: If true when anchor is NW or SW, the float window
---                 would be kept fixed even if the window would be truncated.
---               • hide: If true the floating window will be hidden.
---               • vertical: Split vertically `:vertical`.
---               • split: Split direction: "left", "right", "above", "below".

--- Set or change decoration provider for a `namespace`
---
--- This is a very general purpose interface for having Lua callbacks being
--- triggered during the redraw code.
---
--- The expected usage is to set `extmarks` for the currently redrawn buffer.
--- `nvim_buf_set_extmark()` can be called to add marks on a per-window or
--- per-lines basis. Use the `ephemeral` key to only use the mark for the
--- current screen redraw (the callback will be called again for the next
--- redraw).
---
--- Note: this function should not be called often. Rather, the callbacks
--- themselves can be used to throttle unneeded callbacks. the `on_start`
--- callback can return `false` to disable the provider until the next redraw.
--- Similarly, return `false` in `on_win` will skip the `on_lines` calls for
--- that window (but any extmarks set in `on_win` will still be used). A
--- plugin managing multiple sources of decoration should ideally only set one
--- provider, and merge the sources internally. You can use multiple `ns_id`
--- for the extmarks set/modified inside the callback anyway.
---
--- Note: doing anything other than setting extmarks is considered
--- experimental. Doing things like changing options are not explicitly
--- forbidden, but is likely to have unexpected consequences (such as 100% CPU
--- consumption). doing `vim.rpcnotify` should be OK, but `vim.rpcrequest` is
--- quite dubious for the moment.
---
--- Note: It is not allowed to remove or update extmarks in 'on_line'
--- callbacks.
