Partial port to guard against v8.2.1326 regression.
Co-authored-by: Bram Moolenaar <Bram@vim.org>
The cursor movement autocommand can not detect when the final tabstop $0
is directly adjacent to another tabstop, which prevents ending the
snippet session. The fix is an early return when jumping.
Problem:
Previously, 'null' value in LSP responses were decoded as 'nil'.
This caused ambiguity for fields typed as '? | null' and led to
loss of explicit 'null' values, particularly in 'data' parameters.
Solution:
Decode all JSON 'null' values as 'vim.NIL' and adjust handling
where needed. This better aligns with the LSP specification,
where 'null' and absent fields are distinct, and 'null' should
not be used to represent missing values.
This also enables proper validation of response messages to
ensure that exactly one of 'result' or 'error' is present, as
required by the JSON-RPC specification.
Problem:
Not easy for a user to tell ":restart" to "run this command(s) after restarting".
Solution:
All ":restart" args following the optional +cmd arg are treated as a big cmdline that is passed as a "-c" CLI arg when restarting nvim.
Problem: cannot perform autocompletion
Solution: Add the 'autocomplete' option value
(Girish Palya)
This change introduces the 'autocomplete' ('ac') boolean option to
enable automatic popup menu completion during insert mode. When enabled,
Vim shows a completion menu as you type, similar to pressing |i\_CTRL-N|
manually. The items are collected from sources defined in the
'complete' option.
To ensure responsiveness, this feature uses a time-sliced strategy:
- Sources earlier in the 'complete' list are given more time.
- If a source exceeds its allocated timeout, it is interrupted.
- The next source is then started with a reduced timeout (exponentially
decayed).
- A small minimum ensures every source still gets a brief chance to
contribute.
The feature is fully compatible with other |i_CTRL-X| completion modes,
which can temporarily suspend automatic completion when triggered.
See :help 'autocomplete' and :help ins-autocompletion for more details.
To try it out, use :set ac
You should see a popup menu appear automatically with suggestions. This
works seamlessly across:
- Large files (multi-gigabyte size)
- Massive codebases (:argadd thousands of .c or .h files)
- Large dictionaries via the `k` option
- Slow or blocking LSP servers or user-defined 'completefunc'
Despite potential slowness in sources, the menu remains fast,
responsive, and useful.
Compatibility: This mode is fully compatible with existing completion
methods. You can still invoke any CTRL-X based completion (e.g.,
CTRL-X CTRL-F for filenames) at any time (CTRL-X temporarily
suspends 'autocomplete'). To specifically use i_CTRL-N, dismiss the
current popup by pressing CTRL-E first.
---
How it works
To keep completion snappy under all conditions, autocompletion uses a
decaying time-sliced algorithm:
- Starts with an initial timeout (80ms).
- If a source does not complete within the timeout, it's interrupted and
the timeout is halved for the next source.
- This continues recursively until a minimum timeout (5ms) is reached.
- All sources are given a chance, but slower ones are de-prioritized
quickly.
Most of the time, matches are computed well within the initial window.
---
Implementation details
- Completion logic is mostly triggered in `edit.c` and handled in
insexpand.c.
- Uses existing inc_compl_check_keys() mechanism, so no new polling
hooks are needed.
- The completion system already checks for user input periodically; it
now also checks for timer expiry.
---
Design notes
- The menu doesn't continuously update after it's shown to prevent
visual distraction (due to resizing) and ensure the internal list
stays synchronized with the displayed menu.
- The 'complete' option determines priority—sources listed earlier get
more time.
- The exponential time-decay mechanism prevents indefinite collection,
contributing to low CPU usage and a minimal memory footprint.
- Timeout values are intentionally not configurable—this system is
optimized to "just work" out of the box. If autocompletion feels slow,
it typically indicates a deeper performance bottleneck (e.g., a slow
custom function not using `complete_check()`) rather than a
configuration issue.
---
Performance
Based on testing, the total roundtrip time for completion is generally
under 200ms. For common usage, it often responds in under 50ms on an
average laptop, which falls within the "feels instantaneous" category
(sub-100ms) for perceived user experience.
| Upper Bound (ms) | Perceived UX
|----------------- |-------------
| <100 ms | Excellent; instantaneous
| <200 ms | Good; snappy
| >300 ms | Noticeable lag
| >500 ms | Sluggish/Broken
---
Why this belongs in core:
- Minimal and focused implementation, tightly integrated with existing
Insert-mode completion logic.
- Zero reliance on autocommands and external scripting.
- Makes full use of Vim’s highly composable 'complete' infrastructure
while avoiding the complexity of plugin-based solutions.
- Gives users C native autocompletion with excellent responsiveness and
no configuration overhead.
- Adds a key UX functionality in a simple, performant, and Vim-like way.

Problem: Using `addr` without `range` in nvim_create_user_command gives
"No range allowed" error, inconsistent with `:command -addr` behavior.
Solution: Set EX_RANGE flag when `addr` option is specified to match
`:command` behavior.
This workarounds a bug likely in nvim__get_runtime, and fixes#35124
Though I'd argue it is more correct anyway as the point of
vim.SUBMODULE lazy loading is "only pay for what you use". If no one
has require'vim.diagnostic' yet in LSP or otherwise, there cannot
be any diagostics available and loading the lua module is wasteful.
Problem: Visual block insert on a single line incorrectly triggers two
on_lines callbacks - one for the correct line (0-indexed) and another
for a non-existent additional line.
Solution: Only call changed_lines() in block_insert() when additional
lines beyond the first were actually modified (start.lnum < end.lnum).
Problem:
It's relatively easy to mispress key `a` to (a)llow arbitrary execution
of 'exrc' files. #35050
Solution:
- For exrc files (not directories), remove "allow" menu item.
Require the user to "view" and then explicitly `:trust` the file.
Problem:
diagnostic extmark used for positioning continues to exist after
deleting a range containing it, so it's possible to jump to a
next/previous diagnositc, which isn't visible in any way, including not
being shown via `open_float`.
Solution:
enable `invalidate` flag when setting an extmark to be able to filter
out diagnostics based on `invalid` flag when looking for next/previous
diagnostic to jump to.
When right_gravity is set to true for deactivating tabstop expansion we
have to set end_right_gravity to false to avoid expanding the tabstop
region on the right side. Vice versa for activating tabstop expansion
again.
Problem:
Diagnostic positions are not being updated after text changes, which
means `vim.diagnostic.open_float` and `vim.diagnostic.jump` will work
with outdated positions when text is changed until diagnostics are
updated again (if ever).
Solution:
Create extmarks in `vim.diagnostic.set` and use their positions for
`vim.diagnostic.open_float` and `next_diagnostic` (used by
`vim.diagnostic.jump`, `vim.diagnostic.get_next` and
`vim.diagnostic.get_prev`).

Solution: Add check for self._head == self._tail and return nil early.
Fix#34696
Problem: cannot easily trigger wildcard expansion
Solution: Introduce wildtrigger() function
(Girish Palya)
This PR introduces a new `wildtrigger()` function.
See `:h wildtrigger()`
`wildtrigger()` behaves like pressing the `wildchar,` but provides a
more refined and controlled completion experience:
- Suppresses beeps when no matches are found.
- Avoids displaying irrelevant completions (like full command lists)
when the prefix is insufficient or doesn't match.
- Skips completion if the typeahead buffer has pending input or if a
wildmenu is already active.
- Does not print "..." before completion.
This is an improvement on the `feedkeys()` based autocompletion script
given in vim/vim#16759.

Problem: Routing based on message kinds can be perceived as unpredictable.
Solution: Implement phase 1 of #34281, always showing the full message
in a window dismissed on any user input when it does not fit
in the 'cmdheight'. Also show spill "[+n]" indicator if needed.
Problem: unlike win_close, win_close_othertab could be used to close the
autocommand window from a different tabpage. This causes aucmd_restbuf to close
the wrong window, potentially causing a crash.
Solution: disallow closing it. Also replace a deprecated use of exc_exec in the
test file.
Fixes#21409.
Problem: no check for nvim_open_win opening a new floating window into a closing
buffer, which can lead to crashes.
Solution: call check_split_disallowed; opening a new float semantically splits
from a window, so the same problems as regular splits apply. Also restore the
error if switch_win_noblock in win_set_buf fails (may not be possible to hit
this, but win_set_buf can silently succeed there since #31595).
As the lock check applies to curbuf (not the target buffer) this may feel a bit
restrictive, though this isn't different to how things like ":split" or
nvim_open_win with "split = true" works when targeting a different buffer. Only
checking the target buffer's lock will cause issues if win_set_buf doesn't end
up in the target buffer for whatever reason.
Maybe we could consider checking the lock of the buffer after win_set_buf and
close the window if it's locked (maybe a bit fiddly, especially as closing a
window can fail...), or make the open + switch operation more atomic, like how
Vim does for its popup windows..?
It also used to be the case that win_set_buf would set an error if autocommands
sent us to a different buffer than what was requested, but #31595 appears to
have also changed that... I haven't touched that here.
Problem: can't accurately know if close_buffer directly (e.g: not via autocmds)
decremented b_nwindows. This can cause crashes if win_close_othertab decides to
keep the window after calling close_buffer (if it did not free the buffer), as
b_nwindows may remain out-of-sync.
Solution: change the return value of close_buffer to accurately depict whether
it decremented b_nwindows. Check it in win_close_othertab to avoid a crash.
Similar issues may exist in other places that call close_buffer, but I've not
addressed those here (not to mention only one other place even checks its return
value...)
Problem: TabClosed is fired after close_buffer is called (after b_nwindows is
decremented) and after the tab page is removed from the list, but before it's
freed. This causes inconsistencies such as the removed tabpage having a valid
handle and functions like nvim_tabpage_get_number returning nonsense.
Solution: fire it after free_tabpage. Try to maintain the Nvim-specific
behaviour of setting `<amatch>` to the old tab page number, and the
(undocumented) behaviour of setting `<abuf>` to the buffer it was showing
(close_buffer sets w_buffer to NULL if it was freed, so it should be OK pass it
to apply_autocmds_group, similar to before).
Problem: No check for closing the only non-floating window in a non-current
tabpage that contains floats. This can lead to a tabpage that contains only
floats, causing crashes.
Solution: Copy the relevant check from win_close to win_close_othertab. Fix some
uncovered issues.
