f517fcd148 perf(lsp): use string.buffer for rpc loop
Avoids some table allocations.
In a quick test over 50000 iterations it reduces the time from 130ms to
74 ms

For the test setup details see:

42657e70b8 perf(lsp): optimize content length extraction from rpc headers
- No redundant `:gsub` to turn `-` in `Content-Length` into `_`
- No table allocations only to add and later get the content-length
  header

e56437cd48 feat(lsp): deprecate vim.lsp.start_client #31341
Problem:
LSP module has multiple "start" interfaces.

Solution:
- Enhance vim.lsp.start
- Deprecate vim.lsp.start_client

385fbfb3e7 docs: improve luacats support #30580
Some composite/compound types even as basic as `(string|number)[]` are
not currently supported by the luacats LPEG grammar used by gen_vimdoc.
It would be parsed & rendered as just `string|number`.

Changeset adds better support for these types.

47e6b2233f fix(vim.fs): dirname() returns "." on mingw/msys2 #30480
Problem:
`vim.fs.dirname([[C:\User\XXX\AppData\Local]])` returns "." on
mingw/msys2.

Solution:
- Check for "mingw" when deciding `iswin`.
- Use `has("win32")` where possible, it works in "fast" contexts since
  b02eeb6a72.

45e76acaa0 feat(lsp): support hostname in rpc.connect #30238
Updated the `rpc.connect` function to support connecting to LSP servers
using hostnames, not just IP addresses. This change includes updates to
the documentation and additional test cases to verify the new
functionality.

- Modified `connect` function to resolve hostnames.
- Updated documentation to reflect the change.
- Added test case for connecting using hostname.

Added a TCP echo server utility function to the LSP test suite. This
server echoes the first message it receives and is used in tests to
verify LSP server connections via both IP address and hostname.
Refactored existing tests to use the new utility function.

bcae8be91f docs: vim.lsp.rpc.connect() TCP requires IP address #30219
"localhost" would work if we used
[tcp_connect](ae0387742b/examples/echo-server-client.lua (L42)),
but that will require changes to
[vim.lsp.rpc.connect](318c0415d5/runtime/lua/vim/lsp/rpc.lua (L638)).

81b372fecd fix(lsp): check for nil response from server (#29196)
this only changes the error message, so that it is clear that
the error is with the LSP server, rather than being a crash inside
nvim runtime scripts. We are already doing a lot of validation,
it's just that nil was being overlooked here.

This fixes issue #27395

37d8e50459 fix(lsp): add "silent" option to vim.lsp.start (#28478)
vim.notify cannot be suppressed and it is not always necessary to
display a visible warning to the user if the RPC process fails to start.
For instance, a user may have the same LSP configuration across systems,
some of which may not have all of the LSP server executables installed.
In that case, the user receives a notification every time a file is
opened that they cannot suppress.

Instead of using vim.notify in vim.lsp.rpc, propagate a normal error up
through the call stack and use vim.notify in vim.lsp.start() only if
the "silent" option is not set.

This also updates lsp.start_client() to return an error message as its
second return value if an error occurred, rather than calling vim.notify
directly. Callers of lsp.start_client() will need to update call sites
appropriately if they wish to report errors to the user (or even better,
switch to vim.lsp.start).

a5fe8f59d9 docs: improve/add documentation of Lua types
- Added `@inlinedoc` so single use Lua types can be inlined into the
  functions docs. E.g.

  ```lua
  --- @class myopts
  --- @inlinedoc
  ---
  --- Documentation for some field
  --- @field somefield integer

  --- @param opts myOpts
  function foo(opts)
  end
  ```

  Will be rendered as

  ```
  foo(opts)

    Parameters:
      - {opts} (table) Object with the fields:
               - somefield (integer) Documentation
                 for some field
  ```

- Marked many classes with with `@nodoc` or `(private)`.
  We can eventually introduce these when we want to.

9beb40a4db feat(docs): replace lua2dox.lua
Problem:

The documentation flow (`gen_vimdoc.py`) has several issues:
- it's not very versatile
- depends on doxygen
- doesn't work well with Lua code as it requires an awkward filter script to convert it into pseudo-C.
- The intermediate XML files and filters makes it too much like a rube goldberg machine.

Solution:

Re-implement the flow using Lua, LPEG and treesitter.

- `gen_vimdoc.py` is now replaced with `gen_vimdoc.lua` and replicates a portion of the logic.
- `lua2dox.lua` is gone!
- No more XML files.
- Doxygen is now longer used and instead we now use:
  - LPEG for comment parsing (see `scripts/luacats_grammar.lua` and `scripts/cdoc_grammar.lua`).
  - LPEG for C parsing (see `scripts/cdoc_parser.lua`)
  - Lua patterns for Lua parsing (see `scripts/luacats_parser.lua`).
  - Treesitter for Markdown parsing (see `scripts/text_utils.lua`).
- The generated `runtime/doc/*.mpack` files have been removed.
   - `scripts/gen_eval_files.lua` now instead uses `scripts/cdoc_parser.lua` directly.
- Text wrapping is implemented in `scripts/text_utils.lua` and appears to produce more consistent results (the main contributer to the diff of this change).

ed1b66bd99 refactor(lsp): move more code to client.lua
The dispatchers used by the RPC client should be defined in the client,
so they have been moved there. Due to this, it also made sense to move
all code related to client configuration and the creation of the RPC
client there too.

Now vim.lsp.start_client is significantly simplified and now mostly
contains logic for tracking open clients.

- Renamed client.new -> client.start

ce4ea638c7 fix(lsp): fix incorrect typing and doc for vim.lsp.rpc
Typings introduced in #26032 and #26552 have a few conflicts, so we
merge and clean them up. We also fix some incorrect type annotation in
the `vim.lsp.rpc` package. See the associated PR for more details.

Summary:

- vim.rpc.Dispatchers -> vim.lsp.rpc.Dispatchers
- vim.lsp.rpc.Error -> lsp.ResponseError
- Revise docs

c0952e62fd feat(lua): add vim.system()
feat(lua): add vim.system()

Problem:

  Handling system commands in Lua is tedious and error-prone:
  - vim.fn.jobstart() is vimscript and comes with all limitations attached to typval.
  - vim.loop.spawn is too low level

Solution:

  Add vim.system().
  Partly inspired by Python's subprocess module
  Does not expose any libuv objects.

a37c686d21 docs(lsp): update buf_notify and rpc.notify params types (#21753)
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.
