Notable changes since Nvim 0.10 news-0.11

vim.rpcnotify(0) and rpcnotify(0) broadcast to ALL channels. Previously they would "multicast" only to subscribed channels (controlled by nvim_subscribe()). Plugins and clients that want "multicast" behavior must now maintain their own list of channels.

In the future, vim.rpcnotify() may accept a list of channels, if there is demand for this use-case.

"Dictionary" was renamed to "Dict" internally and in the RPC api-metadata. This is not expected to break clients because there are no known clients that actually use the return_type field or the parameter type names reported by --api-info or nvim_get_api_info().

Renamed nvim__id_dictionary (unsupported/experimental API) to nvim__id_dict.

On Windows, only building with the UCRT runtime is supported.

Translations are turned off by default. Enable by building Nvim with the CMake flag ENABLE_TRANSLATIONS=ON.

The "underline" diagnostics handler sorts diagnostics by severity when using the "severity_sort" option.

Diagnostics are filtered by severity before being passed to a diagnostic handler diagnostic-handlers.

The "virtual_text" handler is disabled by default. Enable with

vim.diagnostic.config({ virtual_text = true })

The order in which signs are placed was changed. Higher priority signs will now appear left of lower priority signs.

hl-CurSearch now behaves the same as Vim and no longer updates on every cursor movement.

Moving in the buffer list using :bnext and similar commands behaves as documented and skips help buffers if run from a non-help buffer, otherwise it moves to another help buffer.

Bells from a terminal buffer are now silent by default, unless 'belloff' option doesn't contain "term" or "all".

Renamed autocmd group nvim_swapfile to nvim.swapfile. default-autocmds If you always want the swapfile dialog, delete the nvim.swapfile group: autocmd! nvim.swapfile.

vim.ui_attach() callbacks for ui-messages msg_show events are executed in api-fast context.

New/enhanced arguments in these existing UI events:

cmdline_hide: Includes level and abort arguments, abort argument indicating if the cmdline was aborted.

cmdline_show:

Prompts that were previously emitted as msg_show events, are now routed through cmdline_show.

hl_id argument to highlight the prompt text.

msg_show:

history argument indicating if the message was added to the history.

new message kinds: "bufwrite", "completion", "list_cmd", "lua_print", "search_cmd", "shell_out/err/ret", "undo", "verbose", wildlist".

TermRequest and TermResponse event-data is now a table. The "sequence" field contains the received sequence. TermRequest also contains a "cursor" field indicating the cursor's position when the sequence was received.

TermCursorNC is removed and no longer supported. Unfocused terminals no longer have a cursor.

vim.lsp.buf.references(), vim.lsp.buf.declaration(), vim.lsp.buf.definition(), vim.lsp.buf.type_definition(), vim.lsp.buf.implementation() and vim.lsp.buf.hover() now support merging the results of multiple clients but no longer trigger the global handlers from vim.lsp.handlers

vim.lsp.buf.typehierarchy() now passes the correct params for each client request.

vim.lsp.handlers.signature_help() is no longer used.

vim.lsp.diagnostic.on_publish_diagnostics() and vim.lsp.diagnostic.on_diagnostic() no longer accept a config parameter and can no longer be configured with vim.lsp.with(). Instead use:

vim.diagnostic.config(config, vim.lsp.diagnostic.get_namespace(client_id))

vim.lsp.util.make_position_params(), vim.lsp.util.make_range_params() and vim.lsp.util.make_given_range_params() now require the position_encoding parameter.

vim.lsp.util.symbols_to_items() now requires the position_encoding parameter.

API functions now consistently return an empty dictionary as vim.empty_dict(). Earlier, a lua-special-tbl was sometimes used.

vim.json.encode() no longer escapes forward slashes "/" by default

The 'statuscolumn' %l item can now be used as a number column segment that changes according to related options. It takes care of alignment, 'number', 'relativenumber' and 'signcolumn' set to "number". The now redundant %r item is no longer treated specially for 'statuscolumn'.

:set {option}< removes the local value for all global-local options instead of just string global-local options.

:setlocal {option}< copies the global value to the local value for number and boolean global-local options instead of removing the local value.

Setting hidden-options now gives an error. In particular, setting 'noshellslash' is now only allowed on Windows.

Query:iter_matches() correctly returns all matching nodes in a match instead of only the last node. This means that the returned table maps capture IDs to a list of nodes that need to be iterated over. For backwards compatibility, an option all=false (only return the last matching node) is provided that will be removed in a future release.

vim.treesitter.language.get_filetypes() always includes the {language} argument in addition to explicitly registered filetypes.

vim.treesitter.language.get_lang() falls back to the {filetype} argument if no languages are explicitly registered.

vim.treesitter.language.add() returns true if a parser was loaded successfully and nil,errmsg otherwise instead of throwing an error.

vim.treesitter.get_parser() and vim.treesitter.start() no longer parse the tree before returning. Scripts must call LanguageTree:parse() explicitly.

local p = vim.treesitter.get_parser(0, 'c')
p:parse()

vim.treesitter.get_parser() expects its buffer to be loaded.

OSC 52 is used as a fallback clipboard provider when no other clipboard-tool is found, even when not using SSH clipboard-osc52. To disable OSC 52 queries, set the "osc52" key of g:termfeatures to false.

v:msgpack_types has the type "binary" removed. msgpackparse() no longer treats BIN, STR and FIXSTR as separate types. Any of these is returned as a string if possible, or a blob if the value contained embedded NUL:s.

Improved API "meta" docstrings and :help documentation.

nvim__ns_set() can set properties for a namespace

nvim_echo() err field to print error messages and chunks accepts highlight group IDs.

nvim_open_win() supports a mouse field that allows configuring mouse interaction with the window separately from focusable field.

nvim_open_win() relative field can be set to "laststatus" and "tabline".

Additions to nvim_buf_set_extmark():

conceal_lines field to conceal an entire line.

hl_group field can be an array of layered groups.

virt_text_pos field accepts value eol_right_align to allow for right aligned text that truncates before covering up buffer text.

virt_lines_overflow field accepts value scroll to enable horizontal scrolling for virtual lines with 'nowrap'.

Highlighting:

Improved styling of :checkhealth and :help buffers.

<S-Tab> in Insert and Select mode maps to vim.snippet.jump({ direction = -1 }) when a snippet is active and jumpable backwards.

vim.diagnostic.config() accepts a "jump" table to specify defaults for vim.diagnostic.jump().

A "virtual_lines" diagnostic handler was added to render diagnostics using virtual lines below the respective code.

The "virtual_text" diagnostic handler accepts a current_line option to only show virtual text at the cursor's line.

Improved paste handling for redo (dot-repeat) and macros (recording):

Redoing a large paste is significantly faster and ignores 'autoindent'.

Replaying a macro with @ also replays pasted text.

On Windows, filename arguments on the command-line prefixed with "~\" or "~/" are now expanded to the user's profile directory, not a relative path to a literal "~" directory.

hl-ComplMatchIns shows matched text of the currently inserted completion.

hl-PmenuMatch and hl-PmenuMatchSel show matched text in completion popup.

gO now works in help, checkhealth, and markdown buffers.

Jump between sections in help and checkhealth buffers with [[ and ]].

CompleteDone now sets the reason key in v:event which specifies the reason for completion being done.

vim.on_key() callbacks can consume the key by returning an empty string.

Improved rendering of LSP hover docs. K-lsp-default

vim.lsp.completion.enable() gained the convert callback which enables customizing the transformation of an LSP CompletionItem to complete-items.

vim.lsp.diagnostic.from() can be used to convert a list of vim.Diagnostic objects into their LSP diagnostic representation.

:checkhealth vim.lsp displays the server version (if available).

Completion side effects (including snippet expansion, execution of commands and application of additional text edits) is now built-in.

vim.lsp.util.locations_to_items() and vim.lsp.util.symbols_to_items() now sets end_col and end_lnum fields.

vim.lsp.buf.format() now supports passing a list of ranges via the range parameter (this requires support for the textDocument/rangesFormatting request).

vim.lsp.buf.signature_help() can now cycle through different signatures using <C-s> and also support multiple clients.

The client now supports 'utf-8' and 'utf-32' position encodings.

vim.lsp.buf.hover() now highlights hover ranges using the hl-LspReferenceTarget highlight group.

Functions in vim.lsp.Client can now be called as methods.

Implemented LSP folding: vim.lsp.foldexpr() https://microsoft.github.io/language-server-protocol/specification/#textDocument_foldingRange

vim.lsp.config() has been added to define default configurations for servers. In addition, configurations can be specified in lsp/<name>.lua.

vim.lsp.enable() has been added to enable servers.

vim.lsp.buf.code_action() resolves the command property during the codeAction/resolve request.

The textDocument/completion request now includes the completion context in its parameters.

Command-line completions for: vim.g, vim.t, vim.w, vim.b, vim.v, vim.o, vim.wo, vim.bo, vim.opt, vim.opt_local, vim.opt_global, vim.env and vim.fn.

Documentation for lua-bit.

gf in Lua buffers can go to module in same repo, runtime-search-path and package.path.

vim.fs.rm() can delete files and directories.

vim.validate() now has a new signature which uses less tables, is more performant and easier to read.

vim.str_byteindex() and vim.str_utfindex() gained overload signatures supporting two new parameters, encoding and strict_indexing.

vim.json.encode() has an option to enable forward slash escaping

vim.fs.abspath() converts paths to absolute paths.

vim.fs.relpath() gets relative path compared to base path.

vim.fs.dir() and vim.fs.find() can now follow symbolic links, the behavior can be turn on using the new follow option.

vim.hl.range() now has a optional timeout field which allows for a timed highlight.

vim.text.indent() indents/dedents text.

'completeopt' flag "fuzzy" enables fuzzy-matching during ins-completion.

'completeopt' flag "preinsert" highlights text to be inserted.

'messagesopt' configures :messages and hit-enter prompt.

'tabclose' controls which tabpage to focus when closing a tabpage.

'eventignorewin' to persistently ignore events in a window.

'winborder' sets the default border for floating-windows.

Significantly reduced redraw time for long lines with treesitter highlighting.

LSP diagnostics and inlay hints are de-duplicated (new requests cancel inflight requests). This greatly improves performance with slow LSP servers.

10x speedup for vim.treesitter.foldexpr() (when no parser exists for the buffer).

Strong treesitter-query caching makes repeat vim.treesitter.query.get() and vim.treesitter.query.parse() calls significantly faster for large queries.

Treesitter highlighting is now asynchronous. To force synchronous parsing, use vim.g._ts_force_sync_parsing = true.

Treesitter folding is now calculated asynchronously.

LanguageTree:parse() now only runs the injection query on the provided range (as long as the language does not have a combined injection), significantly improving treesitter-highlight performance.

Treesitter injection query iteration is now asynchronous, making edits in large buffers with combined injections much quicker.

10x reduction in blocking time when attaching an LSP to a large buffer.

EditorConfig

spelling_language property is now supported.

'inccommand' incremental preview can run on 'nomodifiable' buffers and restores their 'modifiable' state

Commenting

'commentstring' values can now be specified in a Treesitter capture's bo.commentstring metadata field, providing finer grained support for languages like JSX.

-es ("script mode") disables shada by default.

Nvim will fail if the --listen or $NVIM_LISTEN_ADDRESS address is invalid, instead of silently skipping an invalid address.

The terminal now understands the OSC 52 escape sequence to write to the system clipboard (copy). Querying with OSC 52 (paste) is not supported.

hl-StatusLineTerm and hl-StatusLineTermNC define highlights for the status line in terminal windows.

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.

The terminal now supports OSC 8 escape sequences and will display hyperlinks in supporting host terminals.

The terminal now uses the actual cursor, rather than a "virtual" cursor. This means that escape codes sent by applications running in a terminal buffer can change the cursor shape and visibility. However, it also means that the TermCursorNC highlight group is no longer supported: an unfocused terminal window will have no cursor at all (so there is nothing to highlight).

jobstart() gained the "term" flag.

The terminal will send theme update notifications when 'background' is changed and DEC mode 2031 is enabled.

The terminal has experimental support for the Kitty keyboard protocol (sometimes called "CSI u" key encoding). Only the "Disambiguate escape codes" mode is currently supported.

The terminal emits a TermRequest autocommand event when the child process emits an APC control sequence.

TermRequest has a "cursor" field in its event-data indicating the cursor position when the sequence was received.

LanguageTree:node_for_range() gets anonymous and named nodes for a range

vim.treesitter.get_node() now takes an option include_anonymous, default false, which allows it to return anonymous nodes as well as named nodes.

treesitter-directive-trim! can trim all whitespace (not just empty lines) from both sides of a node.

vim.treesitter.get_captures_at_pos() now returns the id of each capture

New TSNode:child_with_descendant(), which efficiently gets the node's child that contains a given node as descendant.

LanguageTree:parse() optionally supports asynchronous invocation, which is activated by passing the on_parse callback parameter.

vim.treesitter.query.set() can now inherit and/or extend runtime file queries in addition to overriding.

LanguageTree:is_valid() now accepts a range parameter to narrow the scope of the validity check.

:InspectTree now shows which nodes are missing.

Bundled markdown highlight queries use conceal_lines metadata to conceal code block fence lines vertically.

vim.treesitter.language.inspect() shows additional information, including parser version for ABI 15 parsers.

TSQuery:disable_pattern() and TSQuery:disable_capture() to turn off a specific pattern or capture in a query.

vim.treesitter.get_captures_at_pos() returns the pattern_id of the pattern used to match each capture.

Query:iter_captures() now accepts an opts parameter, similar to Query:iter_matches().

The builtin UI declares info nvim_set_client_info() on its channel. See startup-tui. To see the current UI info, try this:

:lua =vim.api.nvim_get_chan_info(vim.api.nvim_list_uis()[1].chan)

log messages written by the builtin UI client (TUI, --remote-ui) are now prefixed with "ui" instead of "?".

The TUI will re-query the terminal's background color when a theme update notification is received and Nvim will update 'background' accordingly.

:detach the current UI, let the Nvim server continue running as a background process. Works with the builtin TUI, and all GUIs.

vim.ui.open() (by default bound to gx) accepts an opt.cmd parameter which controls the tool used to open the given path or URL. If you want to globally set this, you can override vim.ui.open using the same approach described at vim.paste().

vim.ui.open() now supports [lemonade](https://github.com/lemonade-command/lemonade) as an option for opening urls/files. This is handy if you are in an ssh connection and use lemonade.

The ins-completion-menu now supports cascading highlight styles. hl-PmenuSel and hl-PmenuMatch both inherit from hl-Pmenu, and hl-PmenuMatchSel inherits highlights from both hl-PmenuSel and hl-PmenuMatch.

vim.diagnostic.setqflist() updates an existing quickfix list with the given title if found

ui-messages content chunks now also contain the highlight group ID.

:checkhealth can display in a floating window, controlled by the g:health variable.

getchar() and getcharstr() have optional {opts} Dict argument to control: cursor behavior, return type, and whether to simplify the returned key.

'scrollbind' now works properly with buffers that contain virtual lines.

The implementation of grapheme clusters (or combining chars mbyte-combining) was upgraded to closely follow extended grapheme clusters as defined by UAX#29 in the unicode standard. Noteworthily, this enables proper display of many more emoji characters than before, including those encoded with multiple emoji codepoints combined with ZWJ (zero width joiner) codepoints.

Custom highlights in 'rulerformat', 'statuscolumn', 'statusline', 'tabline', 'winbar', and the sign/number column are stacked with their respective highlight groups, as opposed to hl-Normal. This is also reflected in the highlights from nvim_eval_statusline(), with a new groups field containing an array of stacked highlight groups.

vim.on_key() callbacks won't be invoked recursively when a callback itself consumes input.

"q" in man pages now uses CTRL-W_q instead of CTRL-W_c to close the current window, and it no longer throws E444 when there is only one window on the screen. Global variable vim.g.pager is removed.

Default 'titlestring' is now implemented with 'statusline' "%" format items. This means the default, empty value is essentially an alias to: %t%(\ %M%)%(\ \(%{expand(\"%:~:h\")}\)%)%a\ -\ Nvim. This is only an implementation simplification, not a behavior change.

option severity_limit for vim.lsp.diagnostic (use min=severity instead vim.diagnostic.severity).
