`buf.code_action` always included diagnostics on a given line from all
clients. Servers should only receive diagnostics they published, and in
the exact same format they sent it.
Should fix https://github.com/neovim/neovim/issues/29500
Problem:
Some language servers (e.g., rust-analyzer, texlab) are desynced when
the user deletes the entire contents of the buffer. This is due to the
discrepancy between how nvim computes diff and how nvim treats empty
buffer.
* diff: If the buffer became empty, then the diff includes the last
line's eol.
* empty buffer: Even if the buffer is empty, nvim regards it as having
a single empty line with eol.
Solution:
Add special case for diff computation when the buffer becomes empty so
that it does not include the eol of the last line.
Problem: CompletionItem in lsp spec mentioned the deprecated attribute
Solution: when item has deprecated attribute set hl_group to DiagnosticDeprecated
in complete function
Problem:
When there are multiple inlay hints present at the same position, they
should be rendered in the order they are received in the response from
LSP as per the LSP spec. Currently, this is not respected.
Solution:
Gather all hints for a given position, and then set it in a single
extmark call instead of multiple set_extmark calls. This leads to fewer
extmark calls and correct inlay hints being rendered.
Although the built-in pum completion mechanism will filter anyway on the
next input it is odd if the initial popup shows entries which don't
match the current prefix.
Using fuzzy match on the label/prefix is compatible with
`completeopt+=fuzzy` and also doesn't seem to break postfix snippet
cases
Closes https://github.com/neovim/neovim/issues/29287
Problem:
For snippets lsp.completion prefers the label if it is shorter than the
insertText or textEdit to support postfix completion cases but clangd
adds decoration characters to labels. E.g.: `•INT16_C(c)`
Solution:
Use parse_snippet on insertText/textEdit before checking if it is
shorter than the label.

This reduces the number of nil checks around buf_versions usage
Test changes were lifted from 5c33815
Co-authored-by: Mathias Fussenegger <f.mathias@zignar.net>
* Revert "fix(lsp): account for changedtick version gap on modified reset (#29170)"
This reverts commit 2e6d295f79.
* Revert "refactor(lsp): replace util.buf_versions with changedtick (#28943)"
This reverts commit 5c33815448.
`lsp.util.buf_versions` was already derived from changedtick (`on_lines`
from `buf_attach` synced the version)
As far as I can tell there is no need to keep track of the state in a
separate table.
The `complete()` mechanism matches completion candidates against
the typed text, so strict pre-filtering isn't necessary.
This is a first step towards supporting postfix snippets (like
`items@insert` in luals)
Problem:
Inlay hints `enable()` does not fully implement the `:help dev-lua` guidelines:
Interface conventions ~
- When accepting a buffer id, etc., 0 means "current buffer", nil means "all
buffers". Likewise for window id, tabpage id, etc.
- Examples: |vim.lsp.codelens.clear()| |vim.diagnostic.enable()|
Solution:
Implement globally enabling inlay hints.
* refactor(lsp): do not rely on `enable` to create autocmds
* refactor(lsp): make `bufstates` a defaulttable
* refactor(lsp): make `bufstate` inherit values from `globalstate`
* feat(lsp): `vim.lsp.inlay_hints` now take effect on all buffers by default
* test(lsp): add basic tests for enable inlay hints for all buffers
* test(lsp): add test cases cover more than one buffer
Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.
Closes https://github.com/neovim/neovim/issues/27004.
Problem:
We need to establish a pattern for `enable()`.
Solution:
- First `enable()` parameter is always `enable:boolean`.
- Update `vim.diagnostic.enable()`
- Update `vim.lsp.inlay_hint.enable()`.
- It was not released yet, so no deprecation is needed. But to help
HEAD users, it will show an informative error.
- vim.deprecate():
- Improve message when the "removal version" is a *current or older* version.
`exec_lua` makes code slighly harder to read, so it's beneficial to
remove it in cases where it's possible or convenient.
Not all `exec_lua` calls should be removed even if the test passes as it
changes the semantics of the test even if it happens to pass.
From https://github.com/neovim/neovim/pull/28155#discussion_r1548185779:
"Note for tests like this, which fundamentally are about conversion, you
end up changing what conversion you are testing. Even if the result
happens to be same (as they often are, as we like the rules to be
consistent if possible), you are now testing the RPC conversion rules
instead of the vim script to in-process lua conversion rules."
From https://github.com/neovim/neovim/pull/28155#discussion_r1548190152:
"A test like this specifies that the cursor is valid immediately and not
after a separate cycle of normal (or an other input-processing) mode."
Problem:
LSP basic_finish test modified in #27899 is flaky again after #28030.
Solution:
Run on_setup() immediately after setup using a before_init callback.
This is the first installment of a multi-PR series significantly
refactoring how highlights are being specified.
The end goal is to have a base set of 20 ish most common highlights,
and then specific files only need to add more groups to that as needed.
As a complicating factor, we also want to migrate to the new default
color scheme eventually. But by sharing a base set, that future PR
will hopefully be a lot smaller since a lot of tests will be migrated
just simply by updating the base set in place.
As a first step, fix the anti-pattern than Screen defaults to ignoring
highlights. Highlights are integral part of the screen state, not
something "extra" which we only test "sometimes". For now, we still
allow opt-out via the intentionally ugly
screen._default_attr_ids = nil
The end goal is to get rid of all of these eventually (which will be
easier as part of the color scheme migration)
Added the following LSP semantic token types to be linked to highlight
groups by default:
* @lsp.type.event
* @lsp.type.keyword
* @lsp.type.modifier
* @lsp.type.number
* @lsp.type.operator
* @lsp.type.regexp
* @lsp.type.string
Problem:
`vim.lsp.diagnostic.on_diagnostic` accepts an undocumented severity_limit
option which is widely used.
Solution:
Deprecate it in favour of `{min = severity}` used in `vim.diagnostic`.
Since this is undocumented, the schedule for removal is accelerated to
0.11.
refactor(lsp): move glob parsing to vim.glob
Moving the logic for using vim.lpeg to create a match pattern from a
glob into `vim.glob`. There are several places in the LSP spec that
use globs, and it's very useful to have glob matching as a
generally-available utility.
This is the command invoked repeatedly to make the changes:
:%s/^\(.*\)|\%(\*\(\d\+\)\)\?$\n\1|\%(\*\(\d\+\)\)\?$/\=submatch(1)..'|*'..(max([str2nr(submatch(2)),1])+max([str2nr(submatch(3)),1]))/g
refactor!: `vim.lsp.inlay_hint()` -> `vim.lsp.inlay_hint.enable()`
Problem:
The LSP specification allows inlay hints to include tooltips, clickable
label parts, and code actions; but Neovim provides no API to query for
these.
Solution:
Add minimal viable extension point from which plugins can query for
inlay hints in a range, in order to build functionality on top of.
Possible Next Steps
---
- Add `virt_text_idx` field to `vim.fn.getmousepos()` return value, for
usage in mappings of `<LeftMouse>`, `<C-LeftMouse>`, etc
Fixes a regression from 5e5f5174e3
Until that commit we had a logic like this:
`local prefix = startbyte and line:sub(startbyte + 1) or line_to_cursor:sub(word_boundary)`
The commit changed the logic and no longer cut off the line at the cursor, resulting in a prefix that included trailing characters
Fixes https://github.com/neovim/neovim/issues/25177
I initially wanted to split this into a refactor commit to make it more
testable, but it appears that already accidentally fixed the issue by
normalizing lnum/col to 0-indexing
This fixes the issue where the LspNotify handlers for inlay_hint /
diagnostics would end up refreshing all attached clients.
The handler would call util._refresh, which called
vim.lsp.buf_request, which calls the method on all attached clients.
Now util._refresh takes an optional client_id parameter, which is used
to specify a specific client to update.
This commit also fixes util._refresh's handling of the `only_visible`
flag. Previously if `only_visible` was false, two requests would be made
to the server: one for the visible region, and one for the entire file.
