Lewis Russell ee41153a94 feat(diagnostic): revert default behaviour of goto_next/prev()
Follow-up to #28490

Problem:

The new behaviour of goto_next/prev() of navigating to the next highest
severity doesn't work well when diagnostic providers have different
interpretations of severities. E.g. the user may be blocked from
navigating to a useful LSP warning, due to some linter error.

Solution:

The behaviour of next highest severity is now a hidden option
`_highest = true`. We can revisit how to integrate this behaviour
during the 0.11 cycle.

NVIM REFERENCE MANUAL
Notable changes since Nvim 0.9 *news*
For changes in the previous release, 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.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.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| has different background.
• |hl-WinBarNC| is similar to |hl-WinBar| but not bold.
• |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 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.
• Treesitter highlight groups have been renamed to be more in line with
upstream tree-sitter and Helix to make it easier to share queries. The full
list is documented in |treesitter-highlight-groups|.
• |vim.lsp.codelens.refresh()| now takes an `opts` argument. With this change,
the default behavior of just refreshing the current buffer has been replaced by
refreshing all buffers.
• |shm-q| now fully hides macro recording message instead of only shortening it.
• Returning any truthy value from a callback passed to |nvim_create_autocmd()|
(rather than just `true`) will delete the autocommand.
• |vim.lsp.util.extract_completion_items()| will no longer return reliable
results, since it does not apply `itemDefaults` when its input is a
`CompletionList`.
Moreover, since support for LSP `completionList.itemDefaults` was added,
some third party plugins might be negatively impacted in case the language
servers support the feature but the plugin does not.
If necessary, the respective capability can be
removed when calling |vim.lsp.protocol.make_client_capabilities()|.
• |:TOhtml| has been rewritten in Lua to support Neovim-specific decorations,
and many options have been removed.
• |nvim_open_win()| now blocks all autocommands when `noautocmd` is set,
rather than just those from setting the `buffer` to display in the window.
==============================================================================
BREAKING CHANGES IN HEAD *news-breaking-dev*
====== Remove this section before release. ======
The following changes to UNRELEASED features were made during the development
cycle (Nvim HEAD, the "master" branch).
• Removed `vim.treesitter.foldtext` as transparent foldtext is now supported
https://github.com/neovim/neovim/pull/20750
• Changed the signature of `vim.lsp.inlay_hint.enable()`.
• Changed the signature of `vim.diagnostic.enable()`.
• Removed vim.iter.map(), vim.iter.filter(), vim.iter.totable().
• Renamed vim.tbl_isarray() to vim.isarray().
• Changed |vim.ui.open()| return-signature to match pcall() convention.
• Renamed Iter:nextback() to Iter:pop()
• Renamed Iter:peekback() to Iter:rpeek()
• Renamed Iter:skipback() to Iter:rskip()
• Removed Iter:nthback(), use Iter:nth() with negative index instead.
• Renamed nvim_complete_set to nvim__complete_set and marked it as
experimental.
==============================================================================
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.
• 'breakindent' performance is significantly improved for wrapped lines.
• Cursor movement, insertion with [count] and |screenpos()| are now faster.
• |'winfixbuf'| keeps a window focused onto a specific buffer
• |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|
• |'foldtext'| can be set to an empty string to disable and render the line:
as normal with regular highlighting and no line wrapping.
• |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.
• Mapping APIs now support abbreviations when mode short-name has suffix "a".
• Better cmdline completion for string option value. |complete-set-option|
• Builtin TUI can now recognize "super" (|<D-|) and "meta" (|<T-|) modifiers in a
terminal emulator that supports |tui-csiu|.
• Editor
• By default, the swapfile "ATTENTION" |E325| dialog is skipped if the
swapfile is owned by a running Nvim process, instead of prompting. If you
always want the swapfile dialog, delete the default SwapExists handler:
`autocmd! nvim_swapfile`. |default-autocmds|
• Navigating the |jumplist| with CTRL+O, CTRL+I behaves more intuitively
when deleting buffers, and avoids "invalid buffer" cases. #25461
• LSP
• LSP method names are available in |vim.lsp.protocol.Methods|.
• Implemented LSP inlay hints: |lsp-inlay_hint|
https://microsoft.github.io/language-server-protocol/specification/#textDocument_inlayHint
• Implemented pull diagnostic textDocument/diagnostic: |vim.lsp.diagnostic.on_diagnostic()|
https://microsoft.github.io/language-server-protocol/specification/#textDocument_diagnostic
• Implemented LSP type hierarchy: |vim.lsp.buf.typehierarchy()|
https://microsoft.github.io/language-server-protocol/specification/#textDocument_prepareTypeHierarchy
• |vim.lsp.status()| consumes the last progress messages as a string.
• LSP client now always saves and restores named buffer marks when applying
text edits.
• LSP client now supports the `positionEncoding` server capability. If a server
responds with the `positionEncoding` capability in its initialization
response, Nvim automatically sets the client's `offset_encoding` field.
• Dynamic registration of LSP capabilities. An implication of this change is
that checking a client's `server_capabilities` is no longer a sufficient
indicator to see if a server supports a feature. Instead use
`client.supports_method(<method>)`. 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`.
• Added support for connecting to servers using named pipes (Windows) or
unix domain sockets (Unix) via |vim.lsp.rpc.connect()|.
• Added support for `completionList.itemDefaults`, reducing overhead when
computing completion items where properties often share the same value
(e.g. `commitCharacters`). Note that this might affect plugins and
language servers that don't support the feature, and in such cases the
respective capability can be unset.
• |vim.lsp.start()| accepts a "silent" option for suppressing messages
if an LSP server failed to start.
• 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.
• `@injection.filename` will try to match the node text via
|vim.filetype.match()| and treat the result as a language name in the same
way as `@injection.language`.
• 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.
• |:InspectTree| shows node ranges in 0-based indexing instead of 1-based
indexing.
• |:InspectTree| shows root nodes
• |:InspectTree| now supports |folding|
• The `#set!` directive can set the "url" property of a node to have the
node emit a hyperlink. Hyperlinks are UI specific: in the TUI, the OSC 8
control sequence is used.
• |vim.treesitter.foldexpr()| now recognizes folds captured using a
quantified query pattern.
• |:Man| now supports `:hide` modifier to open page in the current window.
• |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 linewise
visual selection.
• |vim.diagnostic.count()| returns the number of diagnostics for a given
buffer and/or namespace, by severity. This is a faster alternative to
|vim.diagnostic.get()| when only the number of diagnostics is needed, but
not the diagnostics themselves.
• Introduced |vim.diagnostic.is_enabled()|
• |vim.deepcopy()| has a `noref` argument to avoid hashing table values.
• Terminal buffers emit a |TermRequest| autocommand event when the child
process emits an OSC or DCS control sequence.
• Terminal buffers respond to OSC background and foreground requests. |default-autocmds|
• |vim.version.le()| and |vim.version.ge()| are added to |vim.version|.
• |extmarks| can set a "url" highlight attribute, so the text region can
become a clickable hyperlink (assuming UI support). The TUI renders URLs
using the OSC 8 control sequence, enabling clickable text in supporting
terminals.
• Added |nvim_tabpage_set_win()| to set the current window of a tabpage.
• Clicking on a tabpage in the tabline with the middle mouse button closes it.
• |namespace| can now have window scopes. |nvim_win_add_ns()|
• |extmarks| option `scoped`: only show the extmarks in its namespace's scope.
• Added built-in |commenting| support.
• |vim.fs.root()| finds project root directories from a list of "root
markers".
==============================================================================
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.on_key()| callbacks receive a second argument for keys typed before
mappings are applied.
• |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.
• 'grepprg' uses the -H and -I flags for grep by default,
and defaults to using ripgrep if available.
• |crn| in Normal mode maps to |vim.lsp.buf.rename()|.
• |crr| in Normal mode maps to |vim.lsp.buf.code_action()|.
• |v_CTRL-R_CTRL-R| in Visual mode maps to |vim.lsp.buf.code_action()|.
• "gr" in Normal mode maps to |vim.lsp.buf.references()| |gr-default|
• |i_CTRL-S| in Insert mode maps to |vim.lsp.buf.signature_help()|
• "]d" and "[d" in Normal mode map to |vim.diagnostic.goto_next()| and
|vim.diagnostic.goto_prev()|, respectively. |]d-default| |[d-default|
• <C-W>d (and <C-W><C-D>) map to |vim.diagnostic.open_float()|
|CTRL-W_d-default|
• 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.
• Enabled treesitter highlighting for Lua files.
• The `workspace/didChangeWatchedFiles` LSP client capability is now enabled
by default.
• On Mac or Windows, `libuv.fs_watch` is used as the backend.
• On Linux, `fswatch` (recommended) is used as the backend if available,
otherwise `libuv.fs_event` is used on each subdirectory.
• |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.
• |:lua| with a |[range]| executes that range in the current buffer as Lua code
regardless of its extension.
• |: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 : '<cfile>'), netrw#CheckIfRemote())<CR>
• |vim.lsp.start()| now creates the following default keymaps (assuming the
server supports the feature):
- |K| in Normal mode maps to |vim.lsp.buf.hover()|, 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.
• |vim.diagnostic.get()| and |vim.diagnostic.count()| accept multiple
namespaces rather than just a single namespace.
• |vim.diagnostic.enable()| gained new parameters, and the old signature is
deprecated.
• 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.
• Passing 0 to |nvim_get_chan_info()| gets info about the current channel.
• |:checkhealth| buffer can now be opened in a split window using modifiers like
|:vertical|, |:horizontal| and |:botright|.
• |nvim_open_win()| and |nvim_win_set_config()| now support opening normal (split)
windows, moving floating windows into split windows, and opening windows in
non-current tabpages.
• 'errorfile' (|-q|) accepts `-` as an alias for stdin.
• |--startuptime| reports the startup times for both processes (TUI + server) as separate sections.
• |nvim_buf_call()| and |nvim_win_call()| now preserves any return value (NB: not multiple return values)
• Treesitter
• |Query:iter_matches()|, |vim.treesitter.query.add_predicate()|, and
|vim.treesitter.query.add_directive()| accept a new `all` option which
ensures that all matching nodes are returned as a table. The default option
`all=false` returns only a single node, breaking captures with quantifiers
like `(comment)+ @comment; it is only provided for backward compatibility
and will be removed after Nvim 0.10.
• |vim.treesitter.query.add_predicate()| and
|vim.treesitter.query.add_directive()| now accept an options table rather
than a boolean "force" argument. To force a predicate or directive to
override an existing predicate or directive, use `{ force = true }`.
==============================================================================
