--- 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

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.

--- 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.)
--- Example:
--- ```lua
---   local api = vim.api
---   local pos = api.nvim_win_get_cursor(0)
---   local ns  = api.nvim_create_namespace('my-plugin')
---   -- Create new extmark at line 1, column 1.

--- Creates or updates an `extmark`.

---               • end_col : ending col of the mark, 0-based exclusive.
---               • hl_group : name of the highlight group used to highlight
---                 this mark.
---               • hl_eol : when true, for a multiline highlight covering the
---                 EOL of a line, continue the highlight for the rest of the
---                 screen line (just like for diff and cursorline highlight).
---               • virt_text : virtual text to link to this mark. A list of
---                 [text, highlight] tuples, each representing a text chunk
---                 with specified highlight. `highlight` element can either

---                 highlight groups that will be stacked (highest priority

---                 using `nvim_get_hl_id_by_name()`.
---               • virt_text_pos : position of virtual text. Possible values:
---                 • "eol": right after eol character (default).
---                 • "overlay": display over the specified column, without
---                   shifting the underlying text.
---                 • "right_align": display right aligned in the window.
---                 • "inline": display at the specified column, and shift the
---                   buffer text to the right as needed.
---
---               • virt_text_win_col : position the virtual text at a fixed
---                 window column (starting from the first text column of the
---                 screen line) instead of "virt_text_pos".
---               • virt_text_hide : hide the virtual text when the background
---                 text is selected or hidden because of scrolling with
---                 'nowrap' or 'smoothscroll'. Currently only affects
---                 "overlay" virt_text.
---               • hl_mode : control how highlights are combined with the
---                 highlights of the text. Currently only affects virt_text
---                 highlights, but might affect `hl_group` in later versions.
---                 • "replace": only show the virt_text color. This is the
---                   default.
---                 • "combine": combine with background text color.
---                 • "blend": blend with background text color. Not supported
---                   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

---                 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.
---               • priority: a priority value for the highlight group or sign
---                 attribute. 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. Note: ranges are unsupported and decorations
---                 are only applied to start_row
---               • sign_hl_group: name of the highlight group used to
---                 highlight the sign column text. Note: ranges are
---                 unsupported and decorations are only applied to start_row
---               • number_hl_group: name of the highlight group used to
---                 highlight the number column. Note: ranges are unsupported
---                 and decorations are only applied to start_row
---               • line_hl_group: name of the highlight group used to
---                 highlight the whole line. Note: ranges are unsupported and
---                 decorations are only applied to start_row
---               • cursorline_hl_group: name of the highlight group used to
---                 highlight the line when the cursor is on the same line as
---                 the mark and 'cursorline' is enabled. Note: ranges are
---                 unsupported and decorations are only applied to start_row
---               • 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.

---    without interleaving redraws, RPC requests from other clients, or user
---    interactions (however API methods may trigger autocommands or event
---    processing which have such side effects, e.g. `:sleep` may wake

--- 2. To minimize RPC overhead (roundtrips) of a sequence of many requests.
---
---

---               • pattern or patterns to match exactly.
---                 • For example, if you have `*.py` as that pattern for the

---                   `test.py` will not match the pattern.
---
---               • defaults to clearing all patterns.
---               • NOTE: Cannot be used with {buffer}
---
---             • buffer: (bufnr)
---               • clear only `autocmd-buflocal` autocommands.
---               • NOTE: Cannot be used with {pattern}
---
---             • group: (string|int) The augroup name or id.
---               • NOTE: If not passed, will only delete autocmds not in any group.

--- 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
--- command argument, expanding filenames in a command that otherwise doesn't
--- 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)`.
--- On execution error: fails with Vimscript error, updates v:errmsg.
---
--- @param cmd vim.api.keyset.cmd Command to execute. Must be a Dictionary that can contain the

--- Executes an Ex command.
--- On execution error: fails with Vimscript error, updates v:errmsg.
--- Prefer using `nvim_cmd()` or `nvim_exec2()` over this. To evaluate
--- multiple lines of Vim script or an Ex command directly, use

--- Creates an `autocommand` event handler, defined by `callback` (Lua function or Vimscript function name string) or `command` (Ex command string).
--- Example using Lua callback:
--- ```lua
---     vim.api.nvim_create_autocmd({"BufEnter", "BufWinEnter"}, {

---       pattern = {"*.c", "*.h"},
---       command = "echo 'Entering a C or C++ file'",
---     })

--- ```lua
---   pattern = vim.fn.expand("~") .. "/some/path/*.py"
--- ```

---                literally `autocmd-pattern`.
---              • buffer (integer) optional: buffer number for buffer-local
---                autocommands `autocmd-buflocal`. Cannot be used with

--- Open a new window.
--- Currently this is used to open floating and external windows. 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`.
--- Exactly one of `external` and `relative` must be specified. The `width`
--- and `height` of the new window must be specified.
--- 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.
--- Example (Lua): window-relative float
--- ```lua
---     vim.api.nvim_open_win(0, false,
---       {relative='win', row=3, col=3, width=12, height=3})
--- ```
--- Example (Lua): buffer-relative float (travels as buffer is scrolled)
--- ```lua
---     vim.api.nvim_open_win(0, false,
---       {relative='win', width=12, height=3, bufpos={100,10}})
--- ```
---
--- @param buffer integer Buffer to display, or 0 for current buffer
--- @param enter boolean Enter the window (make it the current window)
--- @param config vim.api.keyset.float_config Map defining the window configuration. Keys:
---               • relative: Sets the window layout to "floating", placed at
---                 (row,col) coordinates relative to:
---                 • "editor" The global editor grid
---                 • "win" Window given by the `win` field, or current
---                   window.
---                 • "cursor" Cursor position in current window.
---                 • "mouse" Mouse position
---
---               • win: `window-ID` for relative="win".
---               • anchor: Decides which corner of the float to place at
---                 (row,col):
---                 • "NW" northwest (default)
---                 • "NE" northeast
---                 • "SW" southwest
---                 • "SE" southeast
---
---               • 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:

---                   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 specifify 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 no buffer-related autocommand
---                 events such as `BufEnter`, `BufLeave` or `BufWinEnter` may
---                 fire from calling this function.

--- 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.
