Problem: When 'wildmode' is set to include "noselect", the popup menu (pum)
incorrectly retained its scroll position when reopened. This
meant that after scrolling down through the menu with `<C-n>`,
reopening the menu (e.g., by retyping the command and
triggering completion again) would show the menu starting from
the previously scrolled position, rather than from the top.
This could confuse users, as the first visible item would not
be the first actual match in the list.
Solution: Ensure that the popup menu resets its scroll position to the
top when reopened (Girish Palya).

Problem:
Closes#31453
Solution:
Introduce `vim.lsp.Capability`, which may serve as the base class for
all LSP features that require caching data. it
- was created if there is at least one client that supports the specific method;
- was destroyed if all clients that support the method were detached.
- Apply the refactor for `folding_range.lua` and `semantic_tokens.lua`.
- Show active features in :checkhealth.
Future:
I found that these features that are expected to be refactored by
`vim.lsp.Capability` have one characteristic in common: they all send
LSP requests once the document is modified. The following code is
different, but they are all for this purpose.
- semantic tokens:
fb8dba413f/runtime/lua/vim/lsp/semantic_tokens.lua (L192-L198)
- inlay hints, folding ranges, document color
fb8dba413f/runtime/lua/vim/lsp/inlay_hint.lua (L250-L266)
I think I can sum up this characteristic as the need to keep certain
data synchronized with the latest version computed by the server.
I believe we can handle this at the `vim.lsp.Capability` level, and
I think it will be very useful.
Therefore, my next step is to implement LSP request sending and data
synchronization on `vim.lsp.Capability`, rather than limiting it to the
current create/destroy data approach.
Problem:
Error when adding a plugin will make all following plugins not
`:packadd`ed
Solution:
- add() should handle errors from :packadd with pcall()

Problem: tests: no test that 'incsearch' is updated after accepting
search completion.
Solution: Add a test case (zeertzjq).
closes: vim/vim#1768208e5b128b8
Problem: 'wildchar' does not work in search contexts
Solution: implement search completion when 'wildchar' is typed
(Girish Palya).
This change enhances Vim's command-line completion by extending
'wildmode' behavior to search pattern contexts, including:
- '/' and '?' search commands
- ':s', ':g', ':v', and ':vim' commands
Completions preserve the exact regex pattern typed by the user,
appending the completed word directly to the original input. This
ensures that all regex elements — such as '<', '^', grouping brackets
'()', wildcards '\*', '.', and other special characters — remain intact
and in their original positions.
---
**Use Case**
While searching (using `/` or `?`) for lines containing a pattern like
`"foobar"`, you can now type a partial pattern (e.g., `/f`) followed by
a trigger key (`wildchar`) to open a **popup completion menu** showing
all matching words.
This offers two key benefits:
1. **Precision**: Select the exact word you're looking for without
typing it fully.
2. **Memory aid**: When you can’t recall a full function or variable
name, typing a few letters helps you visually identify and complete the
correct symbol.
---
**What’s New**
Completion is now supported in the following contexts:
- `/` and `?` search commands
- `:s`, `:g`, `:v`, and `:vimgrep` ex-commands
---
**Design Notes**
- While `'wildchar'` (usually `<Tab>`) triggers completion, you'll have
to use `<CTRL-V><Tab>` or "\t" to search for a literal tab.
- **Responsiveness**: Search remains responsive because it checks for
user input frequently.
---
**Try It Out**
Basic setup using the default `<Tab>` as the completion trigger:
```vim
set wim=noselect,full wop=pum wmnu
```
Now type:
```
/foo<Tab>
```
This opens a completion popup for matches containing "foo".
For matches beginning with "foo" type `/\<foo<Tab>`.
---
**Optional: Autocompletion**
For automatic popup menu completion as you type in search or `:`
commands, include this in your `.vimrc`:
```vim
vim9script
set wim=noselect:lastused,full wop=pum wcm=<C-@> wmnu
autocmd CmdlineChanged [:/?] CmdComplete()
def CmdComplete()
var [cmdline, curpos, cmdmode] = [getcmdline(), getcmdpos(),
expand('<afile>') == ':']
var trigger_char = '\%(\w\|[*/:.-]\)$'
var not_trigger_char = '^\%(\d\|,\|+\|-\)\+$' # Exclude numeric range
if getchar(1, {number: true}) == 0 # Typehead is empty, no more
pasted input
&& !wildmenumode() && curpos == cmdline->len() + 1
&& (!cmdmode || (cmdline =~ trigger_char && cmdline !~
not_trigger_char))
SkipCmdlineChanged()
feedkeys("\<C-@>", "t")
timer_start(0, (_) => getcmdline()->substitute('\%x00', '',
'ge')->setcmdline()) # Remove <C-@>
endif
enddef
def SkipCmdlineChanged(key = ''): string
set ei+=CmdlineChanged
timer_start(0, (_) => execute('set ei-=CmdlineChanged'))
return key == '' ? '' : ((wildmenumode() ? "\<C-E>" : '') .. key)
enddef
**Optional: Preserve history recall behavior**
cnoremap <expr> <Up> SkipCmdlineChanged("\<Up>")
cnoremap <expr> <Down> SkipCmdlineChanged("\<Down>")
**Optional: Customize popup height**
autocmd CmdlineEnter : set bo+=error | exec $'set ph={max([10,
winheight(0) - 4])}'
autocmd CmdlineEnter [/?] set bo+=error | set ph=8
autocmd CmdlineLeave [:/?] set bo-=error ph&
```

Make `vim.iter():take()` and `vim.iter():skip()`
optionally accept predicates to enable takewhile
and skipwhile patterns used in functional
programming.
731e616a79 made it so passing `{env = nil, clear_env = true }` would
pass `{env = {}}` to `vim.uv.spawn`.
However this is not what `clear_env` is (arguably) supposed to do.
If `env=nil` then that implies the uses wants `vim.uv.spawn()` to use
the default environment. Adding `clear_env = true` simply prevents
`NVIM` (the base environment) from being added.
Fixes#34730
Problem: No way to compute intersection of two version ranges, which is
useful when computing version range that fits inside several reference
ranges.
Solution: Add `vim.version.intersect()`.
Problem: `vim.version.range('<=a.b.c')` is not precise when it comes to
its right hand side. This is due to version ranges using exclusive right
hand side. While `vim.version.range('>a.b.c')` is not precise when it
comes to its left hand side because left hand sides are inclusive.
Solution: For '>=a.b.c' increase `to` from 'a.b.c' to the smallest
reasonable version that is bigger than 'a.b.c'. For '<a.b.c' do the same
for `from`.
More proper solution is an explicit control over inclusivity of version
range sides, but it has more side effects and requires design decisions.
Problem: Currently terminal highlight attribute buffers are statically allocated
be the size of `TERM_ATTRS_MAX`. This unique case isn't respected in
some places in the ui_compositor. Due to this, when a terminal window
has lines longer them `TERM_ATTRS_MAX`, the compositor will go past the
end of the buffer causing a crash due to out of bounds access.
Solution: Add check to ensure we don't query terminal highlight attrs
past `TERM_ATTRS_MAX` in `win_line()`.
Fixes#30374
Problem: `tostring()` applied to version range doesn't return
human-readable text with information about the range.
Solution: Add `__tostring()` method.
Problem: tests: need a test for the new-style tutor.tutor, patch
9.1.1384 broke the expected positions for the signs
Solution: Update all number keys in tutor.tutor.json to match the
correct line numbers in tutor.tutor, replace tabs by spaces,
add a screen-dump test to verify it does not regress

Problem: Messages routed to the pager to be shown in full, enter the
pager automatically, yielding another "press-q-prompt".
Solution: Only enter the pager when requested explicitly. Otherwise,
close the pager on the next typed mapping, unless that mapping
entered the pager.
Problem: vim._extui unconditionally creates windows, buffers and the
Vimscript cmdline highlighter when it is first loaded.
Solution: Schedule first creation of the window so that first redraw
happens sooner (still need to create at least the cmdline
window asap as it can have a different highlight through
hl-MsgArea; thus further delaying until the first event that
needs a particular target seems redundant). Load the cmdline
highlighter on the first cmdline_show event.
Problem: When a floating window with high winblend uses a highlight group
with underline (but without guisp), the underline appears red.
Solution: Only blend the special color (for underline/undercurl) if the
foreground highlight actually has underline or undercurl set.
Otherwise, ignore the special color.
Problem: Topline is preemptively updated by line() in WinResized
autocmd with 'splitkeep' != "cursor".
Solution: Set `skip_update_topline` when 'splitkeep' != "cursor".

Problem: ext_messages cannot tell when the screen was cleared, which is
needed to clear visible messages. An empty message is also
never emitted, but clears messages from the message grid.
Solution: Repurpose the "msg_clear" event to be emitted when the screen
was cleared. Emit an empty message with the `empty` kind to
hint to a UI to clear the cmdline area.
- Render Lua types in api.txt.
- Added `DictAs(name)` API type which acts the same as `Dict` (no parens)
when generating the dispatchers, but acts the same as `Dict(name)`
when generating docs.
- Added `Tuple(...)` API type which is the treated the as `Array` for
generating the dispatchers, but is used to document richer types.
- Added `Enum(...)` API type to better document enums
- Improve typing of some API functions.
- Improve c_grammar to properly parse API types and replace string pattern
logic in the parsers.
- Removed all the hardcoded type overrides in gen_eval_files.lua
Problem:
In setup_env, some needed logic is bypassed when clear_env=true.
Solution:
Drop the early return in setup_env().

Problem: ext_messages is implemented to mimic the message grid
implementation w.r.t. scrolling messages, clearing scrolled
messages, hit-enter-prompts and replacing a previous message.
Meanwhile, an ext_messages UI may not be implemented in a way
where these events are wanted. Moreover, correctness of these
events even assuming a "scrolled message" implementation
depends on fragile "currently visible messages" global state,
which already isn't correct after a previous message was
supposed to have been overwritten (because that should not only
happen when `msg_scroll == false`).
Solution: - No longer attempt to keep track of the currently visible
messages: remove the `msg_ext(_history)_visible` variables.
UIs may remove messages pre-emptively (timer based), or never
show messages that don't fit a certain area in the first place.
- No longer emit the `msg(_history)_clear` events to clear
"scrolled" messages. This opens up the `msg_clear` event to
be emitted when messages should actually be cleared (e.g.
when the screen is cleared). May also be useful to emit before
the first message in an event loop cycle as a hint to the UI
that it is a new batch of messages (vim._extui currently
schedules an event to determine that).
- Set `replace_last` explicitly at the few callsites that want
this to be set to true to replace an incomplete status message.
- Don't store a "keep" message to be re-emitted.
Problem:
Not easy to get user-input in prompt-buffer before the user submits the
input. Under the current system user/plugin needs to read the buffer
contents, figure out where the prompt is, then extract the text.
Solution:
- Add prompt_getinput().
- Extract prompt text extraction logic to a separate function
Problem: "cmdline_show" event may be emitted with an invalid cursor
position, causing a redraw that will clear the match highlight.
Solution: Mark the cursor position as valid so that a "cmdline_show"
callback that updates the screen does not clear the match highlight.
Problem:
With `formatoptions+=r`, the prompt prefix "%" is treated as
comment-start (because of global default 'comments' option contains
"%"), so it gets added to the start of the line when a new line
is input in a prompt.
Solution:
Unset the 'comments' option in prompt buffers by default.
Problem: OptionSet autocmd emitted with invalid grids after entering
tabpage with different 'cmdheight'.
Solution: First call `tabpage_check_windows()` before changing 'cmdheight'.
Add a test that exercises the `vim._extui` cmdline.
Problem: ml_get error when updating quickfix buffer with nvim_buf_attach
Solution: use correct lnume parameter in changed_lines for append mode
Fix#34610
Problem: UI buffers may be 'unmodifiable' and use a 'swapfile'.

Problem:
In LSP configs, the function form of `cmd()` cannot easily get the
resolved root dir (workspace). One of the main use-cases of a dynamic
`cmd()` is to be able to start a new server whose binary may be located
*in the workspace* ([example](https://github.com/neovim/nvim-lspconfig/pull/3912)).
Compare `reuse_client()`, which also receives the resolved config.
Solution:
Pass the resolved config to `cmd()`.

Problem: No ext_messages kind for the :command, :version commands.
:version is emitted as multiple events.
Solution: Assign them the "list_cmd" kind. Use `msg_put*` to properly
format the message as a single event.
