the `textDocument/rangeFormatting` nad `textDocument/formatting` did not
pass bufnr to apply_text_edits, meaning edits were applied to
the user's currently active buffer. This could result in text being
applied to the wrong buffer.
`return err_message(tostring(err))` caused errors to be printed as
`table: 0x123456789` instead of showing the error code and error
message.
This also removes some `if err` blocks that never got called because at
the end of `handlers.lua` all the handlers are wrapped with logic that
adds generic error handling.
The `workspace/configuration` handler could fail with the following
error if `config.settings` is nil:
runtime/lua/vim/lsp/util.lua:1432: attempt to index local 'settings' (a nil value)"
This ensures that `config.settings` is always initialized to an empty
table.
Until we support dynamicRegistration, we should handle the client/registerCapability in core. There are still some language servers that send this request despite dynamicRegistration not being registered client-side (we got an upstream fix for the node ones, but this depends on them bumping vscode-languageserver-node).
Change the update of the client.messages.progress table to overwrite only the percentage and message properties on $report, Previously we were overwriting the table which meant client.messages.progress[token].message.title was wiped on report.
When using "au User LspDiagnosticsChanged redrawstatus!", modelines get processed again (see h: doautocmd). Fortunately this can be suppressed using the <nomodeline> flag. this replaces every doautocmd call, that issues a User command, with doautocmd <nomodeline>.
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 :)
