This is necessary in cases where filetype detection acts recursively.
For example, when matching files that end with .bak, the "root" of
the filename is matched again against the same buffer (e.g. a buffer
named "foo.c.bak" will be matched again with the filename "foo.c", using
the same underlying buffer).
This enables vim.filetype.match to match based on a buffer (most
accurate) or simply a filename or file contents, which are less accurate
but may still be useful for some scenarios.
When matching based on a buffer, the buffer's name and contents are both
used to do full filetype matching. When using a filename, if the file
exists the file is loaded into a buffer and full filetype detection is
performed. If the file does not exist then filetype matching is only
performed against the filename itself. Content-based matching does the
equivalent of scripts.vim, and matches solely based on file contents
without any information from the name of the file itself (e.g. for
shebangs).
BREAKING CHANGE: use `vim.filetype.match({buf = bufnr})` instead
of `vim.filetype.match(name, bufnr)`
This re-introduces the fix that the filetype.lua refactor inadvertently reverted.
The fix ensures that in the case when end_lnum is omitted, a string is always returned.
`nvim_get_option_value` and `nvim_set_option_value` better handle
unsetting local options. For instance, this is currently not possible:
vim.bo.tagfunc = nil
This does not work because 'tagfunc' is marked as "local to buffer" and
does not have a fallback global option. However, using :setlocal *does*
work as expected
:setlocal tagfunc=
`nvim_set_option_value` behaves more like :set and :setlocal (by
design), so using these as the underlying API functions beneath vim.bo
and vim.wo makes those two tables act more like :setlocal. Note that
vim.o *already* uses `nvim_set_option_value` under the hood, so that
vim.o behaves like :set.
Steps to reproduce:
1. setting `vim.highlight.on_yank`
```
vim.api.nvim_create_autocmd({ "TextYankPost" }, {
pattern = { "*" },
callback = function()
vim.highlight.on_yank({ timeout = 200 })
end,
})
```
2. repeat typing `yeye` ...
3. causes the following error.
```

Many filetypes from filetype.vim set buffer-local variables, meaning
vim.filetype.match cannot be used without side effects. Instead of
setting these buffer-local variables in the filetype detection functions
themselves, have vim.filetype.match return an optional function value
that, when called, sets these variables. This allows vim.filetype.match
to work without side effects.
Most LSP servers require the notification to correctly load the
settings and for those who don't it doesn't cause any harm.
So far this is done in lspconfig, but with the addition of vim.lsp.start
it should be part of core.
A alternative/subset of https://github.com/neovim/neovim/pull/18506 that should be forward compatible with a potential project system.
Configuration of LSP clients (without lspconfig) now looks like this:
vim.lsp.start({
name = 'my-server-name',
cmd = {'name-of-language-server-executable'},
root_dir = vim.fs.dirname(vim.fs.find({'setup.py', 'pyproject.toml'}, { upward = true })[1]),
})
When yanking another range while previous yank is still highlighted, the
pending timer could clear the highlight almost immediately (especially
when using larger `timeout`, i.e. 2000)
Fix a bug in lsp.buf.rename() where the range returned by the server in
textDocument/prepareRename was interpreted as a byte range directly,
instead of taking the negotiated offset encoding into account. This
caused the placeholder value in vim.ui.input to be incorrect in some
cases, for example when non-ascii characters are used earlier on the
same line.

The vim.health module is detected as a healthcheck, which produces spurious errors:
vim: require("vim.health").check()
========================================================================
- ERROR: Failed to run healthcheck for "vim" plugin. Exception:
function health#check, line 20
Vim(eval):E5108: Error executing lua [string "luaeval()"]:1: attempt to call field 'check' (a nil value)
stack traceback:
[string "luaeval()"]:1: in main chunk
Solution:
Skip vim.health when discovering healthchecks.
- Complete function:
There was lots of unnecessary C code for the complete function, therefore
moving it to Lua and use all the plumbing we have in place to retrieve the
results.
- Moving the module:
It's important we keep nvim lua modules name spaced, avoids conflict with
plugins, luarocks, etc.
Currently the `title`, `message` and `percentage` is stored for a
progress, but there is also an optional `cancellable` that comes in with
both the `WorkDoneProgressBegin` and also `WorkDoneProgressReport`. This
change also stores that value so that a plugin can access it when they
do a lookup in `client.messages`.
Previously the `offset!` directive populated the metadata in such a way
that the new range could be attributed to a specific capture. #14046
made it so the directive simply stored just the new range in the
metadata and information about what capture the range is based from is
lost.
This change reverts that whilst also correcting the docs.
The client state is cleaned up both in client.stop() as well as in the
client.on_exit() handler. Technically, the client has not actually
stopped until the on_exit handler is called, so we should just do this
cleanup there and remove it from client.stop().
This makes the common use case easier.
If one really needs access to all clients, they can create a filter
function which manually calls `get_active_clients`.
