**Problem(?):** Buffers that (for whatever reason) aren't meant to have
a final newline are still parsed with a final newline in `treesitter.c`.
**Solution:** Don't add the newline to the last buffer line if it
shouldn't be there. (This more closely matches the approach of
`read_buffer_into()`.)
This allows us to, say, use a scratch buffer with `noeol` and `nofixeol`
behind the scenes in `get_string_parser()`.
...which would allow us to track injection trees with extmarks in that
case.
...which would allow us to not drop previous trees after reparsing a
different range with `get_parser():parse()`.
...which would prevent flickering when editing a buffer that has 2+
windows to it in view at a time.
...which would allow us to keep our sanity!!!
(one step at a time...)
Problem: Marks are lost after `:bdelete` because `ignore_buf()` filters
out unlisted buffers during shada mark processing.
Solution: Revert to original buffer checks for mark operations, avoiding
`!buf->b_p_bl` condition that incorrectly ignores deleted buffers.
Problem: completion: autocompletion can be improved
Solution: Add support for "longest" and "preinsert" in 'autocomplete';
add preinserted() (Girish Palya)
* Add support for "longest" in 'completeopt' when 'autocomplete'
is enabled. (Note: the cursor position does not change automatically
when 'autocomplete' is enabled.)
* Add support for "preinsert" when 'autocomplete' is enabled. Ensure
"preinsert" works the same with and without 'autocomplete'
* introduce the preinserted() Vim script function, useful for defining
custom key mappings.

Problem: :update should write new file buffers, but previous fix
affected special buffer types (acwrite, nofile, etc.).
Solution: Add bt_nofilename() check to only write new files for
buffers representing real filesystem paths.
Problem: update command does not write new buffers that have
filenames but no corresponding file on disk, even when using ++p flag.
Solution: allow update to write when buffer has filename but file
doesn't exist.
Problem: Wrong display with 'smoothscroll' and long wrapped virtual
text at EOL.
Solution: Handle w_skipcol inside long wrapped virtual text at EOL
(zeertzjq).

Before functional/testnvim.lua was moved from functional/testutil.lua in
052498ed42, it was explicitly preloaded,
but now it is preloaded implicitly via functional/ui/screen.lua.
Also fix warnings about unused variables in other preload.lua files.
- Remove "state" directory after each test, so that a failure in one
test won't interfere with later tests.
- Still make sure the trust file is empty at the end of each test.
Use only a single clear() call in some test/functional/vimscript/ test
files whose test cases have very little side effect.
A downside of using a single clear() is that if a crash happens in one
test case, all following test cases in the same file will also fail, but
these functionalities and tests don't change very often.
Problem: completion: 'autocomplete' cannot be enabled per buffer

Problem: complete: some redraw issues with 'autocomplete'
Solution: Fix the issues (Girish Palya)
This commit contains the following changes:
* Fix that wildtrigger() might leave opened popupmenu around vim/vim#18298
* Remove blinking message on the command line when a menu item from a loaded
buffer is selected during 'autocomplete'
* Add a test for PR vim/vim#18265 to demonstrate why the PR is required for correct
'autocomplete' behavior

Problem: When the popup menu (PUM) occupies more than half the screen
height, it flickers whenever a character is typed or erased.
This happens because the PUM is cleared and the screen is
redrawn before a new PUM is rendered. The extra redraw between
menu updates causes visible flicker.
Solution: A complete, non-hacky fix would require removing the
CmdlineChanged event from the loop and letting autocompletion
manage the process end-to-end. This is because screen redraws
after any cmdline change are necessary for other features to
work.
This change modifies wildtrigger() so that the next typed
character defers the screen update instead of redrawing
immediately. This removes the intermediate redraw, eliminating
flicker and making cmdline autocompletion feel smooth
(Girish Palya).
Trade-offs:
This behavior change in wildtrigger() is tailored specifically for
:h cmdline-autocompletion. wildtrigger() now has no general-purpose use
outside this scenario.

The vim._extui.messages module uses multiple timers that last 2 or 4
seconds. If these timers aren't finished when a test ends, there will
be a 2-second delay on exit with ASAN or TSAN.
Problem:
If there are 2 language servers with different trigger chars (`-` and
`>`), and a keymap inputs both simultaneously (`->`), then `>` doesn't
trigger. We get completion items from server1 only.
This happens because the `completion_timer` for the `-` trigger is still
pending.
Solution:
If the next character arrived enough quickly (< 25 ms), replace the
existing deferred autotrigger with a new one that matches this later
character.
Overriding vim.lsp.handlers['textDocument/formatting'] doesn't work here
because fake_lsp_server_setup() uses a table with __index to specify
client handlers, which takes priority over vim.lsp.handlers[], and as a
result the overridden handler is never called, and the test ends before
the vim.wait() even finishes.
Instead, set a global variable from the handler that is actually reached
(by vim.rpcrequest() from client handler), and avoid stopping the event
loop too early.
Problem:
`gx` does not work on tags in help buffers to open the documentation of that tag in the browser.
Solution:
Get the `optionlink`, `taglink` and `tag` TS nodes and set extmark "url" property.
`gx` then discovers the extmark "url" and opens it.
- Bump zig version to 0.15.1 and workaround zig fetch hang (ziglang/zig#24916)
- add mac os zig build (currently without luajit, linker failure)
- Add windows zig build, currently with very limited testing
This also fixes the following warning in tests with ASAN or TSAN:
-------- Running tests from test/functional/plugin/lsp/inline_completion_spec.lua
RUN T4604 vim.lsp.inline_completion enable() requests or abort when entered/left insert mode: 225.00 ms OK
RUN T4605 vim.lsp.inline_completion get() applies the current candidate: 212.00 ms OK
nvim took 2013 milliseconds to exit after last test
This indicates a likely problem with the test even if it passed!
RUN T4606 vim.lsp.inline_completion get() accepts on_accept callback: 212.00 ms OK
RUN T4607 vim.lsp.inline_completion select() selects the next candidate: 220.00 ms OK
-------- 4 tests from test/functional/plugin/lsp/inline_completion_spec.lua (3437.00 ms total)
-------- Running tests from test/functional/plugin/lsp/linked_editing_range_spec.lua
nvim took 2011 milliseconds to exit after last test
This indicates a likely problem with the test even if it passed!
This fixes the following warning in tests with ASAN or TSAN:
-------- Running tests from test/functional/lua/watch_spec.lua
RUN T4253 vim._watch watch() ignores nonexistent paths: 29.00 ms OK
nvim took 2006 milliseconds to exit after last test
This indicates a likely problem with the test even if it passed!
Problem: There is no way to ensure a stable key order when encoding a JSON string,
which can be useful for comparisons and producing cleaner diffs.
Solution: Introduce a `sort_keys` option for `vim.json.encode()`,which
is disabled by default. When enabled, object keys are sorted in
alphabetical order.
Problem:
LSP logs show misleading "cannot start" messages when editing a filetype
NOT listed in the `config.filetypes` field.
[ERROR][2025-09-13 18:55:56] …/runtime//lua/vim/lsp/log.lua:151
"cannot start cssls due to config error: …/runtime//lua/vim/lsp.lua:423:
cmd: expected expected function or table with executable command,
got table: 0x0104701b18. Info: vscode-css-language-server is not executable"
Solution:
- `can_start`: check `config.filetypes` before checking the rest of the
config.
Problem:
Multigrid UIs have to find out which window to send the input by using
the Nvim focus rules, which are not fully documented.
Furthermore,`getmousepos()` has several problems when multigrid is
enabled, with the main one being that screenrow and screencol are window
relative instead of screen relative, due to the fact that the UI don't
send any absolute coordinates.
Solution:
Allow passing 0 as grid to `nvim_input_mouse`, with absolute
coordinates, which lets nvim determine the actual window to send the
mouse input to. This works as long as nvim is in charge of the window
positioning. If the UI repositions or resizes the windows, it can still
pass the grid it determines like before.
Problem: A 'rulerformat' not part of the statusline is not emitted through
msg_ruler events.
Solution: Build the message chunks to emit as a msg_ruler event.
Problem: First clean start with config containing multiple
`vim.pack.add()` calls requires to explicitly confirm each one.
Although usually a rare occurrence, it still might be tedious.
Solution: Add a third choice during installation confirmation that
approves current and all next installs within current session. It is
reset after session restart.
Problem: defaults: 'diffopt' option value can be improved
Solution: Update diffopt defaults to include "indent-heuristic" and
"inline:char" (Yee Cheng Chin)
The default diff options have not been updated much despite new
functionality having been added to Vim.
- indent-heurstic: This has been enabled by default in Git since
33de716387 in 2017. Given that Vim uses xdiff from Git, it makes sense
to track the default configuration from Git.
- inline:char: This turns on character-wise inline highlighting which is
generally much better than the default inline:simple. It has been
implemented since vim/vim#16881 and we have not seen reports of any issues
with it, and it has received good feedbacks.

Problem:
Crash on startup in some situations due to call to `set_curbuf`
with the current value of `cur_buf`.
Solution:
Switch buffers before doing the wipeout of the stdin buffer.
Use cmdline cmds instead of raw buffer pointers to avoid lifetime issues.
Problem: completion: preinserted text highlighed using ComplMatchIns
Solution: Use highlighting group PreInsert and update the documentation
(Girish Palya).
When "preinsert" is included in 'completeopt', only the PreInsert
highlight group should be applied, whether autocompletion is active or not.
Previously, ComplMatchIns was used when autocompletion was not enabled.

Problem: nvim_win_set_config may crash when attempting to move curwin to a
different tabpage if there is no other non-float available to switch to.
Solution: fix the crash. Fix ONE_WINDOW checks in winframe_find_altwin and
win_altframe to consider floating windows by instead using one_window. Allow
one_window to consider non-current tabpages. We can use one_window in
win_close_othertab now to also better reflect its use in win_close.

Problem:
Currently, prompt_buffer manages `:` mark by itself and exposes it
read-only mark. However when it fails there can be no mitigation made
by plugins. The `:` mark should act like a regular marks and be
modifiable.
Solution:
Allow plugins to set `:` mark.
