`client.messages` could grow unbounded because the default handler only
added new messages, never removing them.
A user either had to consume the messages by calling
`vim.lsp.util.get_progress_messages` or by manually removing them from
`client.messages.progress`. If they didn't do that, using LSP
effectively leaked memory.
To fix this, this deprecates the `messages` property and instead adds a
`progress` ring buffer that only keeps at most 50 messages. In addition
it deprecates `vim.lsp.util.get_progress_messages` in favour of a new
`vim.lsp.status()` and also promotes the `LspProgressUpdate` user
autocmd to a regular autocmd to allow users to pattern match on the
progress kind.
Also closes https://github.com/neovim/neovim/pull/20327
BREAKING CHANGE: LspRequest is no longer a User autocmd but is now a
first class citizen.
LspRequest as a User autocmd had limited functionality. Namely, the only
thing you could do was use the notification to do a lookup on all the
clients' requests tables to figure out what changed.
Promoting the autocmd to a full autocmd lets us set the buffer the
request was initiated on (so people can set buffer-local autocmds for
listening to these events).
Additionally, when used from Lua, we can pass additional metadata about
the request along with the notification, including the client ID, the
request ID, and the actual request object stored on the client's
requests table. Users can now listen for these events and act on them
proactively instead of polling all of the requests tables and looking
for changes.
* Also fix newly found type mismatch.
* Note that it generates new warnings about using @private client
methods. A proper fix would be to revamp the lsp client documentation
altogether.
Problem:
Some built-in ftplugins set omnifunc/tagfunc/formatexpr which causes
lsp.lua:set_defaults() to skip setup of defaults for those filetypes.
For example the C++ ftplugin has:
omnifunc=ccomplete#Complete
Last set from /usr/share/nvim/runtime/ftplugin/c.vim line 30
so the changes done in #95c65a6b221fe6e1cf91e8322e7d7571dc511a71
will always be skipped for C++ files.
Solution:
Overwrite omnifunc/tagfunc/formatexpr options that were set by stock
ftplugin.
Fixes#21001
feat(lsp)!: change semantic token highlighting
Change the default highlights used, and add more highlights per token.
Add an LspTokenUpdate event and a highlight_token function.
:Inspect now shows any highlights applied by token highlighting rules,
default or user-defined.
BREAKING CHANGE: change the default highlight groups used by semantic
token highlighting.
This small changes just ensures that if you're using `convert_input_to_markdown_lines`
without `contents` you don't get a warning (when using something like neodev) that
there is an expected second param, since it can be nil.
Small, but I was getting warnings about my usage of
`vim.lsp.buf_notify(bufnr, method, {example = example})` since the docs
say that `params` must be a string, however this can really be anything
when it's passed to `rpc.notify` since we just end up calling
`vim.json.encode(payload)` on it. This fixes the docs in those two
places and regenerates them.
Problem:
No easy way to position a LSP hover window relative to mouse.
Solution:
Introduce another option to the `relative` key in `nvim_open_win()`.
With this PR it should be possible to override the handler and do something
similar to this https://github.com/neovim/neovim/pull/19481#issuecomment-1193248674
to have hover information displayed from the mouse.
Test case:
```lua
local util = require('vim.lsp.util')
local function make_position_param(window, offset_encoding)
window = window or 0
local buf = vim.api.nvim_win_get_buf(window)
local row, col
local mouse = vim.fn.getmousepos()
row = mouse.line
col = mouse.column
offset_encoding = offset_encoding or util._get_offset_encoding(buf)
row = row - 1
local line = vim.api.nvim_buf_get_lines(buf, row, row + 1, true)[1]
if not line then
return { line = 0, character = 0 }
end
if #line < col then
return { line = 0, character = 0 }
end
col = util._str_utfindex_enc(line, col, offset_encoding)
return { line = row, character = col }
end
local make_params = function(window, offset_encoding)
window = window or 0
local buf = vim.api.nvim_win_get_buf(window)
offset_encoding = offset_encoding or util._get_offset_encoding(buf)
return {
textDocument = util.make_text_document_params(buf),
position = make_position_param(window, offset_encoding),
}
end
local hover_timer = nil
vim.o.mousemoveevent = true
vim.keymap.set({ '', 'i' }, '<MouseMove>', function()
if hover_timer then
hover_timer:close()
end
hover_timer = vim.defer_fn(function()
hover_timer = nil
local params = make_params()
vim.lsp.buf_request(
0,
'textDocument/hover',
params,
vim.lsp.with(vim.lsp.handlers.hover, {
silent = true,
focusable = false,
relative = 'mouse',
})
)
end, 500)
return '<MouseMove>'
end, { expr = true })
```
Currently once you retrieve the lenses you're pretty much stuck with
them as saving new lenses is additive.
Adding a dedicated method to reset lenses allows users to toggle lenses
on/off which can be useful for language servers where they are noisy or
expensive and you only want to see them temporary.
Apply semantic token modifiers as separate extmarks with corresponding
highlight groups (e.g., `@readonly`). This is a low-effort PR to enable
the most common use cases (applying, e.g., italics or backgrounds on top
of type highlights; language-specific fallbacks like `@global.lua` are
also available). This can be replaced by more complicated selector-style
themes later on.

Problem:
The {foo} parameters listed in `:help api` and similar generated docs,
are intended to be a "list" but they aren't prefixed with a list symbol.
This prevents parsers from understanding the list, which forces
generators like `gen_help_html.lua` to use hard-wrapped/preformatted
layout instead of a soft-wrapped "flow" layout.
Solution:
Modify gen_vimdoc.py to prefix {foo} parameters with a "•" symbol.
