Problem: Health check floating window gets closed when pressing 'gO' to show TOC because LSP floating preview system auto-closes on BufEnter events triggered by :lopen.
Solution: Temporarily disable BufEnter event for the current window during TOC operations and adjust window layout to prevent overlap.
Problem:
Closes#31453
Solution:
Introduce `vim.lsp.Capability`, which may serve as the base class for
all LSP features that require caching data. it
- was created if there is at least one client that supports the specific method;
- was destroyed if all clients that support the method were detached.
- Apply the refactor for `folding_range.lua` and `semantic_tokens.lua`.
- Show active features in :checkhealth.
Future:
I found that these features that are expected to be refactored by
`vim.lsp.Capability` have one characteristic in common: they all send
LSP requests once the document is modified. The following code is
different, but they are all for this purpose.
- semantic tokens:
fb8dba413f/runtime/lua/vim/lsp/semantic_tokens.lua (L192-L198)
- inlay hints, folding ranges, document color
fb8dba413f/runtime/lua/vim/lsp/inlay_hint.lua (L250-L266)
I think I can sum up this characteristic as the need to keep certain
data synchronized with the latest version computed by the server.
I believe we can handle this at the `vim.lsp.Capability` level, and
I think it will be very useful.
Therefore, my next step is to implement LSP request sending and data
synchronization on `vim.lsp.Capability`, rather than limiting it to the
current create/destroy data approach.
Problem:
Error when adding a plugin will make all following plugins not
`:packadd`ed
Solution:
- add() should handle errors from :packadd with pcall()

Problem: tests: need a test for the new-style tutor.tutor, patch
9.1.1384 broke the expected positions for the signs
Solution: Update all number keys in tutor.tutor.json to match the
correct line numbers in tutor.tutor, replace tabs by spaces,
add a screen-dump test to verify it does not regress

Problem:
In LSP configs, the function form of `cmd()` cannot easily get the
resolved root dir (workspace). One of the main use-cases of a dynamic
`cmd()` is to be able to start a new server whose binary may be located
*in the workspace* ([example](https://github.com/neovim/nvim-lspconfig/pull/3912)).
Compare `reuse_client()`, which also receives the resolved config.
Solution:
Pass the resolved config to `cmd()`.

Problem: A custom property containing a pair of square brackets will be
treated as a section.
Solution: Change the logic parsing a section, remove the first match
regex `%b[]`.

Problem:
Some LSPs cause the following completion error (reformatted slightly):
Error executing vim.schedule lua callback:
.../runtime/lua/vim/lsp/completion.lua:373
attempt to index field 'range' (a nil value)
This is because an internal function assumes edits are either missing
or of type `TextEdit`, but there's a third [possibility][0] that's not
handled: the `InsertReplaceEdit`.
This was previously reported in at least two issues:
- https://github.com/neovim/neovim/issues/33142
- https://github.com/neovim/neovim/issues/33224
Solution:
Don't assume the edit is a `TextEdit`. This implicitly handles
`InsertReplaceEdit`s.
Also, add a test case for this, which previously caused an error.

Problem:
- Lesson 7.3 (Cmdline Completion) teaches an important way to discover
Nvim features. I think users should learn it before they start
configuring Nvim
- Nvim can be configured in Lua as well, but lesson 7.2 (Configuring
Nvim) only mentions init.vim. And I think Nvim is promoting Lua more
Solution:
- Move lesson 7.2 to be after lesson 7.3
- Lesson 7.2 should teach about init.lua

Problem:
Stopping a language server and then calling vim.lsp.start() with the same name/root will return the old language server that's in the middle of shutting down. vim.lsp.start() won't return a new server until the old process has terminated.
Solution:
Introducing a client._is_stopping field that tracks the shutdown phase, preventing the client from being reused.
Problem:
No way to check if a LSP config is enabled without causing it to
resolve. E.g. `vim.lsp.config['…'] ~= nil` will resolve the config,
which could be an unwanted and somewhat expensive side-effect.
Solution:
Introduce `vim.lsp.is_enabled()`.
**Problem:** For multiline diagnostics, the end column was improperly
calculated by checking the byte index of the character position on the
*start* line.
**Solution:** Calculate the byte index for end_col using the *end* line.
NEW BUILD SYSTEM!
This is a MVP implementation which supports building the "nvim" binary,
including cross-compilation for some targets.
As an example, you can build a aarch64-macos binary from
an x86-64-linux-gnu host, or vice versa
Add CI target for build.zig currently for functionaltests on linux
x86_64 only
Follow up items:
- praxis for version and dependency bumping
- windows 💀
- full integration of libintl and gettext (or a desicion not to)
- update help and API metadata files
- installation into a $PREFIX
- more tests and linters
Problem:
enable() could be more flexible, so that it works even if called "late".
Solution:
- enable(true) calls `doautoall nvim.lsp.enable FileType`.
- enable(false) calls `client:stop()` on matching clients.
This will be useful for e.g. :LspStop/:LspStart also.
Problem:
`FileType` event is fired before checkhealth report is finished, so
user can't override report settings or contents.
https://github.com/neovim/neovim/pull/33172#issuecomment-2833513916
Solution:
- Trigger FileType event later.
- Document how to remove emojis.
Problem:
There are some "boilerplate" steps for new users. Although we are
constantly improving defaults and lifting patterns into core, users
eventually want to know how to start their own config, add plugins, etc.
Solution:
Add `runtime/example_init.lua` and refer to it from docs.
Problem:
Tests call `clear()` even though `clear_notrace()` is already called in
a `before_each()` handler, wasting precious milliseconds!
Solution:
Remove redundant `clear()` calls.
Problem:
Users of the Roslyn (C#) LSP have encountered significant delays when
retrieving pull diagnostics in large documents while using Neovim. For
instance, diagnostics in a 2000-line .cs file can take over 20 seconds
to display after edits in Neovim, whereas in VS Code, diagnostics for
the same file are displayed almost instantly.
As [mparq noted](https://github.com/seblj/roslyn.nvim/issues/93#issuecomment-2508940330)
in https://github.com/seblj/roslyn.nvim/issues/93, VS Code leverages
additional parameters specified in the [LSP documentation for
textDocument/diagnostic](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#documentDiagnosticParams),
specifically:
- previousResultId
- identifier
Solution:
When requesting diagnostics, Neovim should include the
`previousResultId` and `identifier` parameters as part of the request.
These parameters enable the server to utilize caching and return
incremental results.
Support for maintaining state is already present in the
[textDocument/semanticTokens implementation](8f84167c30/runtime/lua/vim/lsp/semantic_tokens.lua (L289)).
A similar mechanism can be implemented in `textDocument/diagnostic` handler.
Problem:
In cases when the (in-process) LSP server responds to the request
immediately and calls `notify_reply_callback` the request will still be
marked as pending, because the code assumes that the response will occur
asynchronously. Then the request will be pending forever, because it was
already set as "completed" before we even set it as "pending".
A workaround is to wrap `notify_replay_callback` in `vim.shedule` ([like
so](https://github.com/neovim/neovim/pull/24338#issuecomment-2809568617)]
but that seems counterintuitive.
Solution:
Handle this case in Client:request().
Problem: Transpiled Lua code from vim9script is not amenable to static
analysis, requiring manual cleanup or ignoring parts of our codebase.
Solution: Revert to pre-rewrite version of (low-impact) legacy plugins
and remove the vim9jit shim.
Problem:
Default 'statusline' is implemented in C and not representable as
a statusline expression. This makes it hard for user configs/plugins to
extend it.
Solution:
- Change the default 'statusline' slightly to a statusline expression.
- Remove the C implementation.
Problem:
`vim.lsp.buf.[implementation|definition|...]({ reuse_win = true })` does not
jump cursor to existing window if buffer is already open.
Steps to reproduce:
1. `nvim repro.lua`
2. Insert anything that lsp can read to open the library definition/implementation, e.g., `vim.keymap.set`
3. open `repro.lua` buffer and the library buffer side by side.
4. type `gd` over `set` to jump to the library definition.
The open buffer is scrolled to the target line, but cursor does not jump.
Solution:
Call nvim_set_current_win if necessary.
Problem: When piping raw manpage content into `:Man!`, buf name is
set to 'man://.. ref', but the check only matches the prefix.
Allows duplicate buffers to be created, triggering E95.
Solution: Match full buf name instead of only 'man://' prefix.
If the buffer already exists, generate a unique name with
'man://' .. 'ref' .. '?new=' format.
Refs: #30132
Problem: Some parts of the tutor are outdated.
- For example, pressing `<Tab>` after typing `:e` does not complete the
command `:edit`, but shows a completion menu with the first entry being
`:earlier`.

Problem:
As checkhealth grows, it is increasingly hard to quickly glance through
the information.
Solution:
Show a summary of ok, warn, and error outputs per section.
Problem: When running functional tests locally, test `syntax/shada.vim works`
fails if the local timezone is not a whole number of hours ahead of UTC.
Solution: Use '!%M' for minute format so that UTC is used in the expected
timestamp instead of the local timezone, just like '%H' for hours.
Problem:
If a config name contains "*" it causes rtp discovery of `lsp/` to
consider the `*` as a wildcard and could lead to strange and unintended
behaviour. For example, accessing the `'*'` config from a `lsp/` file
would cause an infinite loop.
Solution:
- Explicitly disallow a config name from containing wildcards, with the
exception of `'*'`.
- When Resolving `'*'` config, skip the rtp step.
