feat(extmark): support proper multiline ranges The removes the previous restriction that nvim_buf_set_extmark() could not be used to highlight arbitrary multi-line regions The problem can be summarized as follows: let's assume an extmark with a hl_group is placed covering the region (5,0) to (50,0) Now, consider what happens if nvim needs to redraw a window covering the lines 20-30. It needs to be able to ask the marktree what extmarks cover this region, even if they don't begin or end here. Therefore the marktree needs to be augmented with the information covers a point, not just what marks begin or end there. To do this, we augment each node with a field "intersect" which is a set the ids of the marks which overlap this node, but only if it is not part of the set of any parent. This ensures the number of nodes that need to be explicitly marked grows only logarithmically with the total number of explicitly nodes (and thus the number of of overlapping marks). Thus we can quickly iterate all marks which overlaps any query position by looking up what leaf node contains that position. Then we only need to consider all "start" marks within that leaf node, and the "intersect" set of that node and all its parents. Now, and the major source of complexity is that the tree restructuring operations (to ensure that each node has T-1 <= size <= 2*T-1) also need to update these sets. If a full inner node is split in two, one of the new parents might start to completely overlap some ranges and its ids will need to be moved from its children's sets to its own set. Similarly, if two undersized nodes gets joined into one, it might no longer completely overlap some ranges, and now the children which do needs to have the have the ids in its set instead. And then there are the pivots! Yes the pivot operations when a child gets moved from one parent to another.

refactor(grid): change schar_T representation to be more compact Previously, a screen cell would occupy 28+4=32 bytes per cell as we always made space for up to MAX_MCO+1 codepoints in a cell. As an example, even a pretty modest 50*80 screen would consume 50*80*2*32 = 256000, i e a quarter megabyte With the factor of two due to the TUI side buffer, and even more when using msg_grid and/or ext_multigrid. This instead stores a 4-byte union of either: - a valid UTF-8 sequence up to 4 bytes - an escape char which is invalid UTF-8 (0xFF) plus a 24-bit index to a glyph cache This avoids allocating space for huge composed glyphs _upfront_, while still keeping rendering such glyphs reasonably fast (1 hash table lookup + one plain index lookup). If the same large glyphs are using repeatedly on the screen, this is still a net reduction of memory/cache consumption. The only case which really gets worse is if you blast the screen full with crazy emojis and zalgo text and even this case only leads to 4 extra bytes per char. When only <= 4-byte glyphs are used, plus the 4-byte attribute code, i e 8 bytes in total there is a factor of four reduction of memory use. Memory which will be quite hot in cache as the screen buffer is scanned over in win_line() buffer text drawing A slight complication is that the representation depends on host byte order. I've tested this manually by compling and running this in qemu-s390x and it works fine. We might add a qemu based solution to CI at some point.

--- 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.

--- respectively, thus the following are equivalent:

---
--- ```lua
2023-09-14 06:23:01 -07:00
--- vim.api.nvim_buf_get_extmarks(0, my_ns, 0, -1, {})
--- vim.api.nvim_buf_get_extmarks(0, my_ns, {0,0}, {-1,-1}, {})
--- ```
2023-09-14 06:23:01 -07:00
---
--- If `end` is less than `start`, traversal works backwards. (Useful with
--- `limit`, to get the first marks prior to a given position.)

feat(extmark): support proper multiline ranges The removes the previous restriction that nvim_buf_set_extmark() could not be used to highlight arbitrary multi-line regions The problem can be summarized as follows: let's assume an extmark with a hl_group is placed covering the region (5,0) to (50,0) Now, consider what happens if nvim needs to redraw a window covering the lines 20-30. It needs to be able to ask the marktree what extmarks cover this region, even if they don't begin or end here. Therefore the marktree needs to be augmented with the information covers a point, not just what marks begin or end there. To do this, we augment each node with a field "intersect" which is a set the ids of the marks which overlap this node, but only if it is not part of the set of any parent. This ensures the number of nodes that need to be explicitly marked grows only logarithmically with the total number of explicitly nodes (and thus the number of of overlapping marks). Thus we can quickly iterate all marks which overlaps any query position by looking up what leaf node contains that position. Then we only need to consider all "start" marks within that leaf node, and the "intersect" set of that node and all its parents. Now, and the major source of complexity is that the tree restructuring operations (to ensure that each node has T-1 <= size <= 2*T-1) also need to update these sets. If a full inner node is split in two, one of the new parents might start to completely overlap some ranges and its ids will need to be moved from its children's sets to its own set. Similarly, if two undersized nodes gets joined into one, it might no longer completely overlap some ranges, and now the children which do needs to have the have the ids in its set instead. And then there are the pivots! Yes the pivot operations when a child gets moved from one parent to another.

--- If present, the position defined by `end_col` and `end_row` should be
--- after the start position in order for the extmark to cover a range. An
--- earlier end position is not an error, but then it behaves like an empty
--- range (no highlighting).
---
--- @param buffer integer Buffer handle, or 0 for current buffer
--- @param ns_id integer Namespace id from `nvim_create_namespace()`
--- @param line integer Line where to place the mark, 0-based. `api-indexing`
--- @param col integer Column where to place the mark, 0-based. `api-indexing`
--- @param opts vim.api.keyset.set_extmark Optional parameters.
--- • id : id of the extmark to edit.
--- • end_row : ending line of the mark, 0-based inclusive.
--- • 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 be
--- a single highlight group, or an array of multiple highlight
--- groups that will be stacked (highest priority last). A
--- highlight group can be supplied either as a string or as an
--- integer, the latter which can be obtained 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.
--- • virt_text_repeat_linebreak : repeat the virtual text on
--- wrapped lines.
--- • 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
--- 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.
--- • scoped: boolean that indicates that the extmark should only
--- be displayed in the namespace scope. (experimental)

--- 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.

---
---
--- @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.win_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` window to split, or relative window when
--- creating a float (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:
--- • 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.
2023-09-13 22:30:51 -07:00
--- • 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.
---

--- callbacks.

--- • on_win: called when starting to redraw a specific window.
--- ```
--- ["win", winid, bufnr, topline, botline]

---
--- • on_line: called for each buffer line being redrawn. (The
--- interaction with fold lines is subject to change)
--- ```
--- ["line", winid, bufnr, row]

--- • default: Don't override existing definition `:hi-default`
--- • ctermfg: Sets foreground of cterm color `ctermfg`
--- • ctermbg: Sets background of cterm color `ctermbg`
--- • cterm: cterm attribute map, like `highlight-args`. If not
--- set, cterm attributes will match those from the attribute map

--- respectively
--- @param lhs string Left-hand-side `{lhs}` of the mapping.
--- @param rhs string Right-hand-side `{rhs}` of the mapping.
--- @param opts vim.api.keyset.keymap Optional parameters map: Accepts all `:map-arguments` as keys
--- except <buffer>, values are booleans (default false). Also:
--- • "noremap" disables `recursive_mapping`, like `:noremap`
--- • "desc" human-readable description.
--- • "callback" Lua function called in place of {rhs}.
--- • "replace_keycodes" (boolean) When "expr" is true, replace
--- keycodes in the resulting string (see
