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: 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: Crash when using inline diff mode
(Ilya Grigoriev)
Solution: Set tp_diffbuf to NULL when skipping a diff block
(Yee Cheng Chin).
Fix an array out of bounds crash when using diffopt+=inline:char when 4
or more buffers are being diff'ed. This happens when one of the blocks
is empty. The inline highlight logic skips using that buffer's block,
but when another buffer is used later and calls diff_read() to merge the
diff blocks together, it could erroneously consider the empty block's
diff info which has not been initialized, leaving to diff numbers that
are invalid. Later on the diff num is used without bounds checking which
leads to the crash.
Fix this by making sure to unset tp_diffbuf to NULL when we skip a
block, so diff_read() will not consider this buffer to be used within
inline diff. Also, add more bounds checking just to be safe.

Problem: not possible to anchor specific lines in diff mode
Solution: Add support for the anchoring lines in diff mode using the
'diffanchor' option (Yee Cheng Chin).
Adds support for anchoring specific lines to each other while viewing a
diff. While lines are anchored, they are guaranteed to be aligned to
each other in a diff view, allowing the user to control and inform the
diff algorithm what the desired alignment is. Internally, this is done
by splitting up the buffer at each anchor and run the diff algorithm on
each split section separately, and then merge the results back for a
logically consistent diff result.
To do this, add a new "diffanchors" option that takes a list of
`{address}`, and a new "diffopt" option value "anchor". Each address
specified will be an anchor, and the user can choose to use any type of
address, including marks, line numbers, or pattern search. Anchors are
sorted by line number in each file, and it's possible to have multiple
anchors on the same line (this is useful when doing multi-buffer diff).
Update documentation to provide examples.
This is similar to Git diff's `--anchored` flag. Other diff tools like
Meld/Araxis Merge also have similar features (called "synchronization
points" or "synchronization links"). We are not using Git/Xdiff's
`--anchored` implementation here because it has a very limited API
(it requires usage of the Patience algorithm, and can only anchor
unique lines that are the same across both files).
Because the user could anchor anywhere, diff anchors could result in
adjacent diff blocks (one block is directly touching another without a
gap), if there is a change right above the anchor point. We don't want
to merge these diff blocks because we want to line up the change at the
anchor. Adjacent diff blocks were first allowed when linematch was
added, but the existing code had a lot of branched paths where
line-matched diff blocks were handled differently. As a part of this
change, refactor them to have a more unified code path that is
generalized enough to handle adjacent diff blocks correctly and without
needing to carve in exceptions all over the place.

Problem: completion: search completion match may differ in case
(techntools)
Solution: add "exacttext" to 'wildoptions' value (Girish Palya)
This flag does the following:
exacttext
When this flag is present, search pattern completion
(e.g., in |/|, |?|, |:s|, |:g|, |:v|, and |:vim|)
shows exact buffer text as menu items, without
preserving regex artifacts like position
anchors (e.g., |/\<|). This provides more intuitive
menu items that match the actual buffer text. However,
searches may be less accurate since the pattern is not
preserved exactly.
By default, Vim preserves the typed pattern (with
anchors) and appends the matched word. This preserves
search correctness, especially when using regular
expressions or with 'smartcase' enabled. However, the
case of the appended matched word may not exactly
match the case of the word in the buffer.

Problem: completion: can only complete from keyword characters
Solution: remove this restriction, allow completion functions when
called from i_CTRL-N/i_CTRL-P to be triggered from non-keyword
characters (Girish Palya)
Previously, functions specified in the `'complete'` option were
restricted to starting completion only from keyword characters (as
introduced in PR 17065). This change removes that restriction.
With this change, user-defined functions (e.g., `omnifunc`, `userfunc`)
used in `'complete'` can now initiate completion even when triggered
from non-keyword characters. This makes it easier to reuse existing
functions alongside other sources without having to consider whether the
cursor is on a keyword or non-keyword character, or worry about where
the replacement should begin (i.e., the `findstart=1` return value).
The logic for both the “collection” and “filtering” phases now fully
respects each source’s specified start column. This also extends to
fuzzy matching, making completions more predictable.
Internally, this builds on previously merged infrastructure that tracks
per-source metadata. This PR focuses on applying that metadata to
compute the leader string and insertion text appropriately for each
match.
Also, a memory corruption has been fixed in prepare_cpt_compl_funcs().
