Breaking Changes:
- Deprecated all `vim.lsp.util.{*diagnostics*}()` functions.
- Instead, all functions must be found in vim.lsp.diagnostic
- For now, they issue a warning ONCE per neovim session. In a
"little while" we will remove them completely.
- `vim.lsp.callbacks` has moved to `vim.lsp.handlers`.
- For a "little while" we will just redirect `vim.lsp.callbacks` to
`vim.lsp.handlers`. However, we will remove this at some point, so
it is recommended that you change all of your references to
`callbacks` into `handlers`.
- This also means that for functions like |vim.lsp.start_client()|
and similar, keyword style arguments have moved from "callbacks"
to "handlers". Once again, these are currently being forward, but
will cease to be forwarded in a "little while".
- Changed the highlight groups for LspDiagnostic highlight as they were
inconsistently named.
- For more information, see |lsp-highlight-diagnostics|
- Changed the sign group names as well, to be consistent with
|lsp-highlight-diagnostics|
General Enhancements:
- Rewrote much of the getting started help document for lsp. It also
provides a much nicer configuration strategy, so as to not recommend
globally overwriting builtin neovim mappings.
LSP Enhancements:
- Introduced the concept of |lsp-handlers| which will allow much better
customization for users without having to copy & paste entire files /
functions / etc.
Diagnostic Enhancements:
- "goto next diagnostic" |vim.lsp.diagnostic.goto_next()|
- "goto prev diagnostic" |vim.lsp.diagnostic.goto_prev()|
- For each of the gotos, auto open diagnostics is available as a
configuration option
- Configurable diagnostic handling:
- See |vim.lsp.diagnostic.on_publish_diagnostics()|
- Delay display until after insert mode
- Configure signs
- Configure virtual text
- Configure underline
- Set the location list with the buffers diagnostics.
- See |vim.lsp.diagnostic.set_loclist()|
- Better performance for getting counts and line diagnostics
- They are now cached on save, to enhance lookups.
- Particularly useful for checking in statusline, etc.
- Actual testing :)
- See ./test/functional/plugin/lsp/diagnostic_spec.lua
- Added `guisp` for underline highlighting
NOTE: "a little while" means enough time to feel like most plugins and
plugin authors have had a chance to refactor their code to use the
updated calls. Then we will remove them completely. There is no need to
keep them, because we don't have any released version of neovim that
exposes these APIs. I'm trying to be nice to people following HEAD :)

To avoid loading buffers https://github.com/neovim/neovim/pull/12440
changed the logic to not process diagnostics for unloaded buffers.
This is problematic for language servers where compile errors or build
errors are reported via diagnostics. These errors may prevent the
language server from providing all functions and it is difficult for
users to debug it without having access to the errors.
For example, with eclipse.jdt.ls there may be a problem with gradle (the
build tool for java), it results in a diagnostics like this:
org.gradle.toolingapi/build.gradle|1 col 1| Could not run build action using Gradle distribution 'https://services.gradle.org/distributions/gradle-4.8.1-bin.zip'.
This would be invisible to users unless the user happens to open the
right file. In this case the user would actually never see the error,
because the language server isn't attached to the build configuration
files.
This changes the behaviour to at least store the diagnostics. The other
operations which are more expensive are still skipped.
* lsp: remove popup No signature available.
If no signatures. we shouldn't popup No signature available ..It will make noise when use
` api.nvim_command("autocmd CompleteDone <buffer> lua vim.lsp.buf.signature_help()")`
* fix ci test failed remove whitespace
* print message when no signature help
* Add comment
* LSP: Add support for call hierarchies
* LSP: Add support for call hierarchies
* LSP: Add support for call hierarchies
* LSP: Jump to call location
Jump to the call site instead of jumping to the definition of the
caller/callee.
* LSP: add tests for the call hierarchy callbacks
* Fix linting error

The callbacks for `textDocument/documentSymbol` and `workspace/symbol`
never received the `bufnr` argument because the logic that adds error
validation and logging swallowed the argument.
At least the `gopls` language server seems to return nil/null if no code
actions are available. Currently this results in an error:
> Error executing vim.schedule lua callback: shared.lua:199: Expected table, got nil
* Add textDocument/codeAction
* Add callback for workspace/executeCommand
* Escape newlines in codeAction titles
* Return empty list in get_line_diagnostics if no buffer diagnostics
* Add stub documentation
* Validate context parameter in code_action
* Add support for edit in CodeAction responses
* Group diagnostics by line in vim.lsp.util.get_line_diagnostics()
* Advertise code action literal support
* lsp: add workspace/symbol
* refactor symbol callback
* set hierarchical symbol support to true
* add documentation and default mapping

The method with the name 'textDocument/peekDefinition' is not part of
the official language server protocol specification. Therefore no
language server can/will support this. Thereby all related code and
documentation as been removed.
In contrast to other callbacks for LSP requests like
`textDocument/documentSymbols`, does the one for references not open the
quickfix window after the quickfix list was filled. This left the user
in a situation he don't know what or if something had happen.

Before this commit, the LSP client would throw errors when messages
without severity would be sent by the server. We make severity default
to `Error` as a kludge before proper heuristics to discover the severity
of a message are found.
According to the LSP specification, showMessage is what is displayed and logMessage is what is stored.
Since these are different things, I devide the callback into those that match.
fix: #11826
Some lanuguage servers return complementary candidates whose prefixes do not match are also returned.
So we exclude completion candidates whose prefix does not match.
ex) Microsoft python-language-server, rust-analyzer
- In the process, refactored focusable_preview to a util function.
- Add text for locations_to_items of the current line.
- Improve location callback to handle multiple return values by using
set_qflist.
- Remove update_tagstack and leave note for future travelers.
