The current description (especially the "unlimited width" part) is
inaccurate in several ways:
- The size of virtual text can depend on window width. In particular,
the size of "above" virtual text can be equal to window width.
- A double-width character that doesn't fit adds 1 to the virtual column
of the following characters.
- The size of 'showbreak' and 'breakindent' is counted.

Change the second "if" to "because", otherwise it may be misinterpreted
that preinserted() can return non-zero just because these options are

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: 'nowrap' in a modeline may hide malicious code.
Solution: Forcibly use '>' as 'listchars' "extends" if 'nowrap' was set
from a modeline (zeertzjq).
Manual `:setlocal nowrap` disables this behavior. There is a separate
problem with `:set nowrap` that also applies to some other options.

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:
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: 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: 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.

This partially reverts 0b8a72b739,
that is unreverts 15e77a56b7
"priority" is an internal neovim concept which does not occur in shared
queries. Ideally a single priority space should eventually be enough
for our needs. But as we don't want to poke at the usages of
priorities right now in the wider ecosystem,
introduce the "subpriorities" so that treesitter code can distinguish
highlights of the same priorities with different tree nesting depth.
This mainly affects `injection.combined` as parent-tree nodes might appear
in the middle of child-tree nodes which otherwise is not possible.
Continuing the work of #31400
That PR allowed the provider to be invoked multiple times per line.
We want only to do that when there actually is more data later on the
line. Additionally, we want to skip over lines which contain no new
highlight items. The TS query cursor already tells us what the next
position with more data is, so there is no need to reinvoke the range
callback before that.
NB: this removes the double buffering introduced in #32619 which
is funtamentally incompatible with this (nvim core is supposed to keep
track of long ranges by itself, without requiring a callback reinvoke
blitz). Need to adjust the priorities some other way to fix the same issue.
Problem: complete: preinsert does not work well with preinsert
Solution: Make "preinsert" completeopt value work with autocompletion
(Girish Palya)
This change extends Insert mode autocompletion so that 'preinsert' also
works when 'autocomplete' is enabled.
Try: `:set ac cot=preinsert`

Problem:
There is no straightforward way to pretty-print objects as JSON.
The existing `vim.inspect` outputs LON.
Solution:
Introduce an `indent` option for `vim.json.encode()` which enables
human-readable output with configurable indentation.
Adapts PR to upstream: openresty/lua-cjson#114
Problem: The document of nvim_buf_get_extmark currently lacks the
following:
- "details" directory: nvim_buf_get_extmarks() allows an option details
to get a "details" directory in result, but it doesn't mention where
that "details" directory is, what fields does it have.
Solution: Add docs for "details" directory in nvim_buf_get_extmarks()
- Problem: It's not clear for new plugin developers that `:help` uses
a help-tags file for searching the docs, generated by `:helptags`.
- Solution: Hint to the |:helptags| docs for regenerating the tags
file for their freshly written documentation.

Problem:
The callback passed to `vim.wait` cannot return results directly, it
must set upvalues or globals.
local rv1, rv2, rv3
local ok = vim.wait(200, function()
rv1, rv2, rv3 = 'a', 42, { ok = { 'yes' } }
return true
end)
Solution:
Let the callback return values after the first "status" result.
local ok, rv1, rv2, rv3 = vim.wait(200, function()
return true, 'a', 42, { ok = { 'yes' } }
end)
Problem:
Nvim does not have a core concept for indicating "progress" of
long-running tasks. The LspProgress event is specific to LSP.
Solution:
- `nvim_echo` can emit `kind="progress"` messages.
- Emits a `Progress` event.
- Includes new fields (id, status, percent) in the `msg_show` ui-event.
- The UI is expected to overwrite any message having the same id.
- Messages have a globally unique ID.
- `nvim_echo` returns the message ID.
- `nvim_echo(… {id=…})` updates existing messages.
Example:
local grp = vim.api.nvim_create_augroup("Msg", {clear = true})
vim.api.nvim_create_autocmd('Progress', {
pattern={"term"},
group = grp,
callback = function(ev)
print(string.format('event fired: %s', vim.inspect(ev))..'\n')
end
})
-- require('vim._extui').enable({enable=true, msg={target='msg', timeout=1000}})
vim.api.nvim_echo({{'searching'}}, true, {kind='progress', percent=80, status='running', title="terminal(ripgrep)"})
local id = vim.api.nvim_echo({{'searching'}}, true, {kind='progress', status='running', percent=10, title="terminal(ripgrep)"})
vim.api.nvim_echo({}, true, {id = id, kind='progress', percent=20, status = 'running', title='find tests'})
vim.api.nvim_echo({}, true, {id = id, kind='progress', status='running', percent=70})
vim.api.nvim_echo({{'complete'}}, true, {id = id, kind='progress', status='success', percent=100, title="find tests"})
Followups:
- Integrate with 'statusline' by listening to the Progress autocmd event.
- Integrate progress ui-event with `vim._extui`.
Problem: completion: not possible to delay the autcompletion
Solution: add the 'autocompletedelay' option value (Girish Palya).
This patch introduces a new global option 'autocompletedelay'/'acl' that
specifies the delay, in milliseconds, before the autocomplete menu
appears after typing.
When set to a non-zero value, Vim waits for the specified time before
showing the completion popup, allowing users to reduce distraction from
rapid suggestion pop-ups or to fine-tune the responsiveness of
completion.
The default value is 0, which preserves the current immediate-popup
behavior.

Problem: fuzzy-matching can be improved
Solution: Implement a better fuzzy matching algorithm
(Girish Palya)
Replace fuzzy matching algorithm with improved fzy-based implementation
The
[current](https://www.forrestthewoods.com/blog/reverse_engineering_sublime_texts_fuzzy_match/)
fuzzy matching algorithm has several accuracy issues:
* It struggles with CamelCase
* It fails to prioritize matches at the beginning of strings, often
ranking middle matches higher.
After evaluating alternatives (see my comments
[here](https://github.com/vim/vim/issues/17531#issuecomment-3112046897)
and
[here](https://github.com/vim/vim/issues/17531#issuecomment-3121593900)),
I chose to adopt the [fzy](https://github.com/jhawthorn/fzy) algorithm,
which:
* Resolves the aforementioned issues.
* Performs better.
Implementation details
This version is based on the original fzy
[algorithm](https://github.com/jhawthorn/fzy/blob/master/src/match.c),
with one key enhancement: **multibyte character support**.
* The original implementation supports only ASCII.
* This patch replaces ascii lookup tables with function calls, making it
compatible with multibyte character sets.
* Core logic (`match_row()` and `match_positions()`) remains faithful to
the original, but now operates on codepoints rather than single-byte
characters.
Performance
Tested against a dataset of **90,000 Linux kernel filenames**. Results
(in milliseconds) show a **\~2x performance improvement** over the
current fuzzy matching algorithm.

Problem: diff: using diff anchors with hidden buffers fails silently
Solution: Give specific error message for diff anchors when using hidden
buffers (Yee Cheng Chin).
Diff anchors currently will fail to parse if a buffer used for diff'ing
is hidden. Previously it would just fail as the code assumes it would
not happen normally, but this is actually possible to do if `closeoff`
and `hideoff` are not set in diffopt. Git's default diff tool "vimdiff3"
also takes advantage of this.
This fix this properly would require the `{address}` parser to be
smarter about whether a particular address relies on window position or
not (e.g. the `'.` address requires an active window, but `'a` or `1234`
do not). Since hidden diff buffers seem relatively niche, just provide a
better error message / documentation for now. This could be improved
later if there's a demand for it.
