The official developer documentation in in :h dev-lua-doc specifies to
use "--@" for special/magic tokens. However, this format is not
consistent with EmmyLua notation (used by some Lua language servers) nor
with the C version of the magic docstring tokens which use three comment
characters.
Further, the code base is currently split between usage of "--@",
"---@", and "--- @". In an effort to remain consistent, change all Lua
magic tokens to use "---@" and update the developer documentation
accordingly.
Add a new function to redraw diagnostics from the current diagnostic
cache, without receiving a "publishDiagnostics" message from the server.
This is already being done in two places in the Lua stdlib, so this
function unifies that functionality in addition to providing it to third
party plugins.
An example use case for this could be a command or key-binding for
toggling diagnostics virtual text. The virtual text configuration option
can be toggled using `vim.lsp.with` followed by
`vim.lsp.diagnostic.redraw()` to immediately redraw the diagnostics
with the updated setting.
Passing `nil` is equivalent to passing 0, i.e. it simply uses the
current buffer number.
This fixes a bug when vim.lsp.diagnostic.disable() is called without
arguments.
Add two new methods to allow diagnostics to be disabled (and re-enabled)
in the current buffer. When diagnostics are disabled they are simply not
displayed to the user, but they are still sent by the server and
processed by the client.
Disabling diagnostics can be helpful in a number of scenarios. For
example, if one is working on a buffer with an overwhelming amount of
diagnostic warnings it can be helpful to simply disable diagnostics
without disabling the LSP client entirely. This also allows users more
flexibility on when and how they may want diagnostic information to be
displayed. For example, some users may not want to display diagnostic
information until after the buffer is first written.
Adds indentation that matches the number prefix to ensure diagnostic
messages spawning multiple lines align.
Before:
Diagnostics:
1. • Variable not in scope: red :: t0 -> t
• Perhaps you meant one of these:
‘rem’ (imported from Prelude), ‘read’ (imported from Prelude),
‘pred’ (imported from Prelude)
2. • Variable not in scope: repeDoubleColon :: [Char] -> t0
• Perhaps you meant ‘replaceDoubleColon’ (line 32)
After:
Diagnostics:
1. • Variable not in scope: red :: t0 -> t
• Perhaps you meant one of these:
‘rem’ (imported from Prelude), ‘read’ (imported from Prelude),
‘pred’ (imported from Prelude)
2. • Variable not in scope: repeDoubleColon :: [Char] -> t0
• Perhaps you meant ‘replaceDoubleColon’ (line 32)
`lsp.diagnostic.get_all()` was returning diagnotics for `:bwipeout`-ed
buffers because the diagnostic cache is not cleared. The first argument
of on_detach callback is the string "detach", not the bufnr.
Currently, for large number of diagnostics, the delay in populating
loclist may be sufficient for a user to switch to another window,
resulting in the loclist being populated on the wrong window.
Allow to sort diagnostics (and thus signs and virtual text) by severity, so that
the most important message is shown first.
vim.lsp.handlers['textDocument/publishDiagnostics'] = vim.lsp.with(
vim.lsp.diagnostic.on_publish_diagnostics, {
severity_sort = true,
}
)
Fixes https://github.com/neovim/neovim/issues/13929
* lsp: client stop cleanups
* Add diagnostic clearing to client.stop() method used by nvim-lspconfig
* Clear diagnostic cache to prevent stale diagnostics on client restart
* lsp: Add test for vim.lsp.diagnostic.reset
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>.
* lsp: Remove duplicate `diagnostics` fallback in diagnostic.display
* lsp: Expose all diagnostics
Before the changes in #12655 it was possible to retrieve all diagnostics
via `vim.lsp.util.diagnostics_by_buf`.
This adds a `diagnostic.get_all()` to enable users to retrieve all
diagnostics.
Use cases for that could include loading all diagnostics into the
quickfix list, or to build an enhanced goto_next that can move across
buffers.
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 :)
