Problem: When preparing the parameters for a code actions LSP request,
the code set `context.diagnostics` when processing the first LSP client,
and then reused those `context.diagnostics` for subsequent LSP clients.
This meant that the second and next LSP clients got diagnostics that
did not originate from them, and they did not get the diagnostics that
they sent.
Solution: Avoid setting `context.diagnostics` (which is referenced by
all clients). Instead, set `params.context.diagnostics` directly, which
is specific to a single client.
Fixes#30001
Caused by #29501
(cherry picked from commit 7031949be0)
`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:
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.
LspDetach is now triggered by the main on_detach callback that is added
when an LSP client is attached to a buffer. The semantic_tokens module
already includes a LspDetach handler that does the right thing. When the
LspDetach trigger was added to the main LSP on_detach, it created a race
condition in semantic tokens when a buffer was deleted that would
trigger both its own on_detach and the LspDetach handlers. If the former
came last, an error was thrown trying to delete a non-existent augroup
(destroy() was being called twice).

feat(lsp): update LSP healthcheck format (#28980)
This is mostly an aesthetic change, although there are a few new pieces
of information included. Originally I wanted to investigate including
server capabilities in the healthcheck, but until we have the ability to
fold/unfold text in health checks that would be too much information.

Ref: #27807, #28058, #23291, #26520
Rename the field `result` to `params` in the `data` table for
`LspProgress` autocmds. This aligns with LspNotify.
The previous name was chosen because the initial handler implementation
mistakenly had a parameter name `result` instead of `params` for the
`$/progress` LSP "notification" handler. However, `params` would be a
more appropriate name that is more consistent with the underlying LSP
type (`ProgressParams`).

Problem:
inlay_hint `enable(<no args>)` does not activate inlay hints on open
buffers. If a buffer does not have a corresponding `bufstate` in
`bufstates`, then `enable` all buffers will not take effect on it.
Solution:
Make the effective range determined by the loaded buffers.
Fix#28624
reverts e0d92b9cc2#28502
Problem:
`vim.ui.open()` has a `pcall()` like signature, under the assumption
that this is the Lua idiom for returning result-or-error. However, the
`result|nil, errmsg|nil` pattern:
- has precedent in:
- `io.open`
- `vim.uv` (`:help luv-error-handling`)
- has these advantages:
- Can be used with `assert()`:
```
local result, err = assert(foobar())
```
- Allows LuaLS to infer the type of `result`:
```
local result, err = foobar()
if err then
...
elseif result then
...
end
```
Solution:
- Revert to the `result|nil, errmsg|nil` pattern.
- Document the pattern in our guidelines.
Experimental and subject to future changes.
Add a way to redraw certain elements that are not redrawn while Nvim is waiting
for input, or currently have no API to do so. This API covers all that can be
done with the :redraw* commands, in addition to the following new features:
- Immediately move the cursor to a (non-current) window.
- Target a specific window or buffer to mark for redraw.
- Mark a buffer range for redraw (replaces nvim__buf_redraw_range()).
- Redraw the 'statuscolumn'.
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
vim.notify cannot be suppressed and it is not always necessary to
display a visible warning to the user if the RPC process fails to start.
For instance, a user may have the same LSP configuration across systems,
some of which may not have all of the LSP server executables installed.
In that case, the user receives a notification every time a file is
opened that they cannot suppress.
Instead of using vim.notify in vim.lsp.rpc, propagate a normal error up
through the call stack and use vim.notify in vim.lsp.start() only if
the "silent" option is not set.
This also updates lsp.start_client() to return an error message as its
second return value if an error occurred, rather than calling vim.notify
directly. Callers of lsp.start_client() will need to update call sites
appropriately if they wish to report errors to the user (or even better,
switch to vim.lsp.start).
Problem:
`vim.ui.open` unnecessarily invents a different success/failure
convention. Its return type was changed in 57adf8c6e0, so we might as
well change it to have a more conventional form.
Solution:
Change the signature to use the `pcall` convention of `status, result`.
Problem:
Besides being redundant with vim.iter():flatten(), `tbl_flatten` has
these problems:
- Has `tbl_` prefix but only accepts lists.
- Discards some results! Compare the following:
- iter.flatten():
```
vim.iter({1, { { a = 2 } }, { 3 } }):flatten():totable()
```
- tbl_flatten:
```
vim.tbl_flatten({1, { { a = 2 } }, { 3 } })
```
Solution:
Deprecate tbl_flatten.
Note:
iter:flatten() currently fails ("flatten() requires a list-like table")
on this code from gen_lsp.lua:
local anonym = vim.iter({ -- remove nil
anonymous_num > 1 and '' or nil,
'---@class ' .. anonymous_classname,
}):flatten():totable()
Should we enhance :flatten() to work for arrays?
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.
Problem:
vim.ui.open "locks up" Nvim if the spawned process does not terminate. #27986
Solution:
- Change `vim.ui.open()`:
- Do not call `wait()`.
- Return a `SystemObj`. The caller can decide if it wants to `wait()`.
- Change `gx` to `wait()` only a short time.
- Allows `gx` to show a message if the command fails, without the
risk of waiting forever.
To avoid repeatedly requesting a buffer multiple times before a request is completed, the current implementation puts the requested buffer into the active_refreshes table before requesting.
But since we only remove the buffer from active_refreshes in the lsp-handler of textDocument/codeLens, this will cause if the user sends a request that cannot trigger lsp-handler (for example, if there is an LSP server attached to the current buffer, and especially when the user creates an autocmd which performs vim.lsp.codelens.refresh after the BufEnter event is triggered like in the document example), this buffer will be put into active_refreshes, and there is no way to remove it, which will result in all subsequent vim.lsp.codelens.refresh not requesting textDocument/codeLens.
According to the LSP specification, the CodeLens.command is optional but the CodeLens.command.command is not optional, which means the correct representation of a display-only code lens is indeed one with a command with a title to display and an empty string as command.
Problem:
Some servers don't report progress during initialize unless the client
sets the `workDoneToken`
See https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initiatingWorkDoneProgress
In particular:
> There is no specific client capability signaling whether a client will
> send a progress token per request. The reason for this is that this is
> in many clients not a static aspect and might even change for every
> request instance for the same request type. So the capability is signal
> on every request instance by the presence of a workDoneToken property.
And:
> Servers can also initiate progress reporting using the
> window/workDoneProgress/create request. This is useful if the server
> needs to report progress outside of a request (for example the server
> needs to re-index a database). The token can then be used to report
> progress using the same notifications used as for client initiated
> progress.
So far progress report functionality was relying entirely on the latter.
Solution:
Set a `workDoneToken`
