*news.txt* Nvim NVIM REFERENCE MANUAL Notable changes in Nvim 0.10 from 0.9 *news* For changes in Nvim 0.9, see |news-0.9|. Type |gO| to see the table of contents. ============================================================================== BREAKING CHANGES *news-breaking* The following changes may require adaptations in user config or plugins. • In some cases, the cursor in the Nvim |TUI| used to blink even without configuring 'guicursor' as mentioned in |cursor-blinking|. This was a bug that has now been fixed. If your cursor has stopped blinking, add the following (or similar, adapted to user preference) to your |config| file: >vim set guicursor+=n-v-c:blinkon500-blinkoff500 < • |vim.tbl_islist()| now checks whether a table is actually list-like (i.e., has integer keys without gaps and starting from 1). For the previous behavior (only check for integer keys, allow gaps or not starting with 1), use |vim.tbl_isarray()|. • "#" followed by a digit no longer stands for a function key at the start of the lhs of a mapping. • `:behave` was removed. - If you used `:behave xterm`, the following is equivalent: >vim set mousemodel=extend < - If you used `:behave mswin`, the following is equivalent: >vim set selection=exclusive set selectmode=mouse,key set mousemodel=popup set keymodel=startsel,stopsel < • When switching windows, |CursorMoved| autocommands trigger when Nvim is back in the main loop rather than immediately. This is more compatible with Vim. • |-l| ensures output ends with a newline if the script prints messages and doesn't cause Nvim to exit. • |LspRequest| and LspProgressUpdate (renamed to |LspProgress|) autocmds were promoted from a |User| autocmd to first class citizen. • Renamed `vim.treesitter.playground` to `vim.treesitter.dev`. • Removed functions from the |vim.json| module: • Unnecessary, undocumented functions which caused global side-effects. • `vim.json.null` is redundant with `vim.NIL`. • `vim.json.array_mt` (and related) is redundant with `vim.empty_dict()`. • Removed some Vim 5.0<= option compatibilities: • |'backspace'| no longer supports number values. Instead: • for `backspace=0` set `backspace=` (empty) • for `backspace=1` set `backspace=indent,eol` • for `backspace=2` set `backspace=indent,eol,start` (default behavior in Nvim) • for `backspace=3` set `backspace=indent,eol,nostop` • |'backupdir'| and |'directory'| will no longer remove a `>` at the start of the option. • |LanguageTree:parse()| will no longer parse injections by default and now requires an explicit range argument to be passed. If injections are required, provide an explicit range via `parser:parse({ start_row, end_row })`. • |vim.lsp.util.parse_snippet()| will now strictly follow the snippet grammar defined by LSP, and hence previously parsed snippets might now be considered invalid input. • |OptionSet| autocommand args |v:option_new|, |v:option_old|, |v:option_oldlocal|, |v:option_oldglobal| now have the type of the option instead of always being strings. |v:option_old| is now the old global value for all global-local options, instead of just string global-local options. • Local value for a global-local number/boolean option is now unset when the option is set (e.g. using |:set| or |nvim_set_option_value()|) without a scope, which means they now behave the same way as string options. • Signs placed through the legacy |sign-commands| are now stored and displayed as |extmarks| internally. Along with the following changes: • A sign placed twice in the same group with the same identifier will be moved. • Legacy signs are always deleted along with the line it is placed on. • Legacy and extmark signs will show up in both |:sign-place-list| and |nvim_buf_get_extmarks()|. • Legacy and extmark signs are displayed and listed with the same priority: line number -> priority -> sign id -> recently placed • Default color scheme has been updated to be "Nvim branded" and accessible. Use `:colorscheme vim` to revert to the old legacy color scheme. Here is a list of Nvim specific highlight groups which are now defined in a meaningfully different way and might need an update: • |hl-FloatBorder| is linked to |hl-NormalFloat| instead of |hl-WinSeparator|. • |hl-NormalFloat| is not linked to |hl-Pmenu|. • |hl-WinBar| is linked to |hl-StatusLine|. • |hl-WinBarNC| is linked to |hl-StatusLineNC| instead of |hl-WinBar|. • |hl-WinSeparator| is linked to |hl-Normal| instead of |hl-VertSplit|. This also might result into some color schemes looking differently due to them relying on an implicit assumptions about how highlight groups are defined by default. To account for this, define all attributes of highlight groups explicitly. Alternatively, use `:colorscheme vim` or `:source $VIMRUNTIME/colors/vim.lua` to restore previous definitions. • 'termguicolors' is enabled by default when Nvim is able to determine that the host terminal emulator supports 24-bit color. ============================================================================== BREAKING CHANGES IN HEAD *news-breaking-dev* The following breaking changes were made during the development cycle to unreleased features on Nvim HEAD. • ... • ... ============================================================================== NEW FEATURES *news-features* The following new APIs and features were added. • Performance: • 'diffopt' "linematch" scoring algorithm now favours larger and less groups https://github.com/neovim/neovim/pull/23611 • Treesitter highlighting now parses injections incrementally during screen redraws only for the line range being rendered. This significantly improves performance in large files with many injections. • |vim.iter()| provides a generic iterator interface for tables and Lua iterators |for-in|. • |vim.ringbuf()| creates ring buffers. • |vim.keycode()| translates keycodes in a string. • |'smoothscroll'| option to scroll by screen line rather than by text line when |'wrap'| is set. • |nvim_buf_set_extmark()| supports inline virtual text. • 'foldtext' now supports virtual text format. |fold-foldtext| • The terminal buffer now supports reflow (wrapped lines adapt when the buffer is resized horizontally). Note: Lines that are not visible and kept in |'scrollback'| are not reflown. • |vim.system()| for running system commands. • |vim.lpeg| and |vim.re| expose the bundled Lpeg expression grammar parser and its regex interface. • |nvim_win_text_height()| computes the number of screen lines occupied by a range of text in a given window. • |nvim_set_keymap()| and |nvim_del_keymap()| now support abbreviations. • Better cmdline completion for string option value. |complete-set-option| • Builtin TUI can now recognize "super" (|)`. It considers both the dynamic capabilities and static `server_capabilities`. • `anchor_bias` option to |lsp-handlers| aids in positioning of floating windows. • |vim.lsp.util.locations_to_items()| sets the `user_data` of each item to the original LSP `Location` or `LocationLink`. • Treesitter • Bundled parsers and queries (highlight, folds) for Markdown, Python, and Bash. • |vim.treesitter.query.omnifunc()| for treesitter query files (set by default). • |Query:iter_matches()| now has the ability to set the maximum start depth for matches. • `@injection.language` now has smarter resolution and will fall back to language aliases (e.g., filetype or custom shorthands) registered via |vim.treesitter.language.register()| and/or attempt lower case variants of the text. • The `#set!` directive now supports `injection.self` and `injection.parent` for injecting either the current node's language or the parent |LanguageTree|'s language, respectively. • |vim.treesitter.query.edit()| allows live editing of treesitter queries. • Improved error messages for query parsing. • |vim.treesitter.foldtext()| applies treesitter highlighting to foldtext. • |vim.ui.open()| opens URIs using the system default handler (macOS `open`, Windows `explorer`, Linux `xdg-open`, etc.) • |vim.wo| can now be double indexed for |:setlocal| behaviour. Currently only `0` for the buffer index is currently supported. • Lua type annotations for: • `vim.*` • `vim.fn.*` • `vim.api.*` • `vim.v.*` • Improved messages for type errors in `vim.api.*` calls (including `opts` params) • Functions that take a severity as an optional parameter (e.g. |vim.diagnostic.get()|) now also accept a list of severities |vim.diagnostic.severity| • New RPC client type `msgpack-rpc` is added for |nvim_set_client_info()| to support fully MessagePack-RPC compliant clients. • Floating windows can now show footer with new `footer` and `footer_pos` config fields. Uses |hl-FloatFooter| by default. • Floating windows can now be hidden by setting `hide` in |nvim_open_win()| or |nvim_win_set_config()|. • |:terminal| command now accepts some |:command-modifiers| (specifically |:horizontal| and those that affect splitting a window). • |$NVIM_APPNAME| can be set to a relative path instead of only a name. • |:fclose| command. • |vim.snippet| handles expansion of snippets in LSP format. • 'complete' option supports "f" flag for completing buffer names. • |vim.base64.encode()| and |vim.base64.decode()| encode and decode strings using Base64 encoding. • The |TermResponse| autocommand event can be used with |v:termresponse| to read escape sequence responses from the terminal. • A clipboard provider which uses OSC 52 to copy the selection to the system clipboard is now bundled by default and will be automatically enabled under certain conditions. |clipboard-osc52| • 'termsync' option asks the terminal emulator to buffer screen updates until the redraw cycle is complete. Requires support from the terminal. • |vim.text.hexencode()| and |vim.text.hexdecode()| convert strings to and from byte representations. • 'completeopt' option supports "popup" flag to show extra information in a floating window. • |nvim_input_mouse()| supports mouse buttons "x1" and "x2". • |v_Q-default| and |v_@-default| repeat a register for each line of a visual selection. ============================================================================== CHANGED FEATURES *news-changed* The following changes to existing APIs or features add new behavior. • |vim.tbl_contains()| now works for general tables and allows specifying a predicate function that is checked for each value. (Use |vim.list_contains()| for checking list-like tables (integer keys without gaps) for literal values.) • |vim.region()| can use a string accepted by |getpos()| as position. • |vim.diagnostic.config()| now accepts a function for the virtual_text.prefix option, which allows for rendering e.g., diagnostic severities differently. • Defaults: • On Windows 'isfname' does not include ":". Drive letters are handled correctly without it. (Use |gF| for filepaths suffixed with ":line:col"). • 'comments' includes "fb:•". • 'shortmess' includes the "C" flag. • Automatic linting of treesitter query files (see |ft-query-plugin|). Can be disabled via: >lua vim.g.query_lint_on = {} < • Enabled treesitter highlighting for treesitter query files. • Enabled treesitter highlighting for help files. • The `workspace/didChangeWatchedFiles` LSP client capability is now enabled by default. • |LspRequest| autocmd callbacks now contain additional information about the LSP request status update that occurred. • |:source| without arguments treats a buffer with its 'filetype' set to "lua" as Lua code regardless of its extension. • |:checkhealth| buffer now implements |folding|. The initial folding status is defined by the 'foldenable' option. • |:Man| now respects 'wrapmargin' • |gx| now uses |vim.ui.open()| and not netrw. To customize, you can redefine `vim.ui.open` or remap `gx`. To continue using netrw (deprecated): >vim :call netrw#BrowseX(expand(exists("g:netrw_gx")? g:netrw_gx : ''), netrw#CheckIfRemote()) • |vim.lsp.start()| now maps |K| to use |vim.lsp.buf.hover()| if the server supports it, unless |'keywordprg'| was customized before calling |vim.lsp.start()|. • Terminal buffers started with no arguments (and use 'shell') close automatically if the job exited without error, eliminating the (often unwanted) "[Process exited 0]" message. • |vim.diagnostic.config()| now accepts virtual text relevant options to |nvim_buf_set_extmark()| (e.g. "virt_text_pos" and "hl_mode") in its "virtual_text" table, which gives users more control over how diagnostic virtual text is displayed. • Extmarks now fully support multi-line ranges, and a single extmark can be used to highlight a range of arbitrary length. The |nvim_buf_set_extmark()| API function already allowed you to define such ranges, but highlight regions were not rendered consistently for a range that covers more than one line break. This has now been fixed. Signs defined as part of a multi-line extmark also apply to every line in the range, not just the first. In addition, |nvim_buf_get_extmarks()| has gained an "overlap" option to return such ranges even if they started before the specified position. • The following flags were added to |nvim_buf_set_extmark()|: - "undo_restore": opt-out extmarks of precise undo tracking. - "invalidate": automatically hide or delete extmarks. - "virt_text_repeat_linebreak": repeat virtual text on wrapped lines. • LSP hover and signature help now use Treesitter for highlighting of Markdown content. Note that syntax highlighting of code examples requires a matching parser and may be affected by custom queries. • Support for rendering multibyte characters using composing characters has been enhanced. The maximum limit have been increased from 1+6 codepoints to 31 bytes, which is guaranteed to fit all chars from before but often more. NOTE: the regexp engine still has a hard-coded limit of considering 6 composing chars only. • |vim.wait()| is no longer allowed to be called in |api-fast|. • Vimscript function |exists()| supports checking |v:lua| functions. • Added "force_crlf" option field in |nvim_open_term()|. • Attempting to set an invalid keycode option (e.g. `set t_foo=123`) no longer gives an error. • |:checkhealth| buffer can now be opened in a split window using modifiers like |:vertical|, |:horizontal| and |:botright|. ============================================================================== REMOVED FEATURES *news-removed* The following deprecated functions or APIs were removed. • Vimball support - :Vimuntar command • Support for legacy treesitter injection queries • 'shortmess' flags: - |shm-f|. Always uses "(3 of 5)", never "(file 3 of 5)" - |shm-i|. Always use "[noeol]". - |shm-x|. Always use "[dos]", "[unix]" and "[mac]" - |shm-n|. Always use "[New]". ============================================================================== DEPRECATIONS *news-deprecations* The following functions are now deprecated and will be removed in a future release. • Configuring |diagnostic-signs| using |:sign-define| or |sign_define()|. Use the "signs" key of |vim.diagnostic.config()| instead. • Checkhealth functions: - |health#report_error|, |vim.health.report_error()| Use |vim.health.error()| instead. - |health#report_info|, |vim.health.report_info()| Use |vim.health.info()| instead. - |health#report_ok|, |vim.health.report_ok()| Use |vim.health.ok()| instead. - |health#report_start|, |vim.health.report_start()| Use |vim.health.start()| instead. - |health#report_warn|, |vim.health.report_warn()| Use |vim.health.warn()| instead. • |API| functions: - |nvim_buf_get_option()| Use |nvim_get_option_value()| instead. - |nvim_buf_set_option()| Use |nvim_set_option_value()| instead. - |nvim_get_option()| Use |nvim_get_option_value()| instead. - |nvim_set_option()| Use |nvim_set_option_value()| instead. - |nvim_win_get_option()| Use |nvim_get_option_value()| instead. - |nvim_win_set_option()| Use |nvim_set_option_value()| instead. • vim.lsp functions: - |vim.lsp.util.get_progress_messages()| Use |vim.lsp.status()| instead. - |vim.lsp.get_active_clients()| Use |vim.lsp.get_clients()| instead. - |vim.lsp.for_each_buffer_client()| Use |vim.lsp.get_clients()| instead. - |vim.lsp.util.trim_empty_lines()| Use |vim.split()| with `trimempty` instead. - |vim.lsp.util.try_trim_markdown_code_blocks()| - |vim.lsp.util.set_lines()| - |vim.lsp.util.extract_completion_items()| - |vim.lsp.util.parse_snippet()| - |vim.lsp.util.text_document_completion_list_to_complete_items()| • `vim.loop` has been renamed to |vim.uv|. • vim.treesitter.languagetree functions: - |LanguageTree:for_each_child()| Use |LanguageTree:children()| (non-recursive) instead. • The "term_background" UI option |ui-ext-options| is deprecated and no longer populated. Background color detection is now performed in Lua by the Nvim core, not the TUI. vim:tw=78:ts=8:sw=2:et:ft=help:norl:
