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]),
})
Currently this is more or less a straight off reimplementation,
but this allow further optimizations down the line, especially
for avoiding memory allocations of rpc objects.
Current score for "make functionaltest; make oldtest" on a -DEXITFREE build:
is 117 055 352 xfree(ptr != NULL) calls (that's NUMBERWANG!).
Also avoid referring to mappings as "keymaps" in commands and docs.
*map_empty_rhs* *map-empty-rhs*
You can create an empty {rhs} by typing nothing after a single CTRL-V (you
have to type CTRL-V two times). Unfortunately, you cannot do this in a vimrc
file.
- 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.
Problem:
1. The main log routine does not protect itself against recursion.
log_lock() doesn't guard against recursion, it would deadlock...
2. 22b52dd462 (#11501) regressed 6f27f5ef91 (#10172), because
set_init_1..process_spawn tries to log (see backtrace below), but the
mutex isn't initialized yet. Even if the mutex were valid, we don't
want early logging to fallback to stderr because that can break
embedders when stdio is used for RPC.

Solution:
1. Check for recursion, show "internal error" message.
- FUTURE: when "remote TUI" is merged, can we remove log_lock()?
2. Skip logging if log_init wasn't called yet.
Adds an `smods` key to `nvim_create_user_command` Lua command callbacks,
which has command modifiers but in a structured format. This removes the
need to manually parse command modifiers. It also reduces friction in
using `nvim_cmd` inside a Lua command callback.
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.
Previously, there was a bug where setting the local value of 'winbar' to
itself would cause winbar to appear on a floating window, which is
undesirable. This fix makes it so that it's explicitly required for the
window-local value of 'winbar' for a floating window to be set in order
for winbar to be shown on that window.
Problem: The terminal debugger uses various global variables.
Solution: Add a dictionary to hold the terminal debugger preferences.

Omit popup menu.
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`.
Neovim already removed `evim` (or any similar flags). The 'insertmode'
option is a weird remnant, so get rid of it.
The 'insertmode' option is replaced with a script that closely emulates
the option. This script is documented at :help 'insertmode'
Problem: smart/C/lisp indenting is optional, which makes the code more
complex, while it only reduces the executable size a bit.
Solution: Graduate FEAT_CINDENT, FEAT_SMARTINDENT and FEAT_LISP.

The docs for `nvim_buf_set_extmark` mention that you can create a new
extmark when passing in `id=0`, however if you do this you'll get an
error since the code checks that id is positive.
```
id is not a positive integer
```
This change re-words the sentence to make it clearer.
The current approach of using `on_attach` callbacks for configuring
buffers for LSP is suboptimal:
1. It does not use the standard Nvim interface for driving and hooking
into events (i.e. autocommands)
2. There is no way for "third parties" (e.g. plugins) to hook into the
event. This means that *all* buffer configuration must go into the
user-supplied on_attach callback. This also makes it impossible for
these configurations to be modular, since it all must happen in the
same place.
3. There is currently no way to do something when a client detaches from
a buffer (there is no `on_detach` callback).
The solution is to use the traditional method of event handling in Nvim:
autocommands. When a LSP client is attached to a buffer, fire a
`LspAttach`. Likewise, when a client detaches from a buffer fire a
`LspDetach` event.
This enables plugins to easily add LSP-specific configuration to buffers
as well as enabling users to make their own configurations more modular
(e.g. by creating multiple LspAttach autocommands that each do
something unique).
