Problem: cannot get information about command line completion
Solution: add CmdlineLeavePre autocommand and cmdcomplete_info() Vim
script function (Girish Palya)
This commit introduces two features to improve introspection and control
over command-line completion in Vim:
- Add CmdlineLeavePre autocmd event:
A new event triggered just before leaving the command line and before
CmdlineLeave. It allows capturing completion-related state that is
otherwise cleared by the time CmdlineLeave fires.
- Add cmdcomplete_info() Vim script function:
Returns a Dictionary with details about the current command-line
completion state.
These are similar in spirit to InsertLeavePre and complete_info(),
but focused on command-line mode.
**Use case:**
In [[PR vim/vim#16759](https://github.com/vim/vim/pull/16759)], two examples
demonstrate command-line completion: one for live grep, and another for
fuzzy file finding. However, both examples share two key limitations:
1. **Broken history recall (`<Up>`)**
When selecting a completion item via `<Tab>` or `<C-n>`, the original
pattern used for searching (e.g., a regex or fuzzy string) is
overwritten in the command-line history. This makes it impossible to
recall the original query later.
This is especially problematic for interactive grep workflows, where
it’s useful to recall a previous search and simply select a different
match from the menu.
2. **Lack of default selection on `<CR>`**
Often, it’s helpful to allow `<CR>` (Enter) to accept the first match
in the completion list, even when no item is explicitly selected. This
behavior is particularly useful in fuzzy file finding.
----
Below are the updated examples incorporating these improvements:
**Live grep, fuzzy find file, fuzzy find buffer:**
```vim
command! -nargs=+ -complete=customlist,GrepComplete Grep VisitFile()
def GrepComplete(arglead: string, cmdline: string, cursorpos: number):
list<any>
return arglead->len() > 1 ? systemlist($'grep -REIHns "{arglead}"' ..

enddef
def VisitFile()
if (selected_match != null_string)
var qfitem = getqflist({lines: [selected_match]}).items[0]

var pos = qfitem.vcol > 0 ? 'setcharpos' : 'setpos'
exec $':b +call\ {pos}(".",\ [0,\ {qfitem.lnum},\ {qfitem.col},\ 0]) {qfitem.bufnr}'
setbufvar(qfitem.bufnr, '&buflisted', 1)

def FuzzyBuffer(arglead: string, _: string, _: number): list<string>
var bufs = execute('buffers', 'silent!')->split("\n")
var altbuf = bufs->indexof((_, v) => v =~ '^\s*\d\+\s\+#')
if altbuf != -1
[bufs[0], bufs[altbuf]] = [bufs[altbuf], bufs[0]]
endif
return arglead == '' ? bufs : bufs->matchfuzzy(arglead)
enddef
nnoremap <leader><bs> :Buffer <c-@>
var selected_match = null_string
autocmd CmdlineLeavePre : SelectItem()
def SelectItem()
selected_match = ''
if getcmdline() =~ '^\s*\%(Grep\|Find\|Buffer\)\s'
var info = cmdcomplete_info()
if info != {} && info.pum_visible && !info.matches->empty()
selected_match = info.selected != -1 ? info.matches[info.selected] : info.matches[0]
setcmdline(info.cmdline_orig). # Preserve search pattern in history
endif
endif
enddef
```
**Auto-completion snippet:**
```vim
set wim=noselect:lastused,full wop=pum wcm=<C-@> wmnu
autocmd CmdlineChanged : CmdComplete()
def CmdComplete()
var [cmdline, curpos] = [getcmdline(), getcmdpos()]
if getchar(1, {number: true}) == 0 # Typehead is empty (no more pasted input)
&& !pumvisible() && curpos == cmdline->len() + 1
&& cmdline =~ '\%(\w\|[*/:.-]\)$' && cmdline !~ '^\d\+$' # Reduce noise
feedkeys("\<C-@>", "ti")
SkipCmdlineChanged() # Suppress redundant completion attempts
# Remove <C-@> that get inserted when no items are available
timer_start(0, (_) => getcmdline()->substitute('\%x00', '', 'g')->setcmdline())
endif
enddef
cnoremap <expr> <up> SkipCmdlineChanged("\<up>")
cnoremap <expr> <down> SkipCmdlineChanged("\<down>")
autocmd CmdlineEnter : set bo+=error
autocmd CmdlineLeave : set bo-=error
def SkipCmdlineChanged(key = ''): string
set ei+=CmdlineChanged
timer_start(0, (_) => execute('set ei-=CmdlineChanged'))
return key != '' ? ((pumvisible() ? "\<c-e>" : '') .. key) : ''
enddef
```
These customizable snippets can serve as *lightweight* and *native*
alternatives to picker plugins like **FZF** or **Telescope** for common,
everyday workflows. Also, live grep snippet can replace **cscope**
without the overhead of building its database.

Problem:
'winblend' does not display text behind blank unicode characters other than 0x20 ascii space.
Solution:
In ui_compositor.c -> compose_line() check for either 0x20 or 0x80A0E2 (utf8 \u2800).
Problem:
Cursor is visible in "hidden" floating window.
Solution:
Hide cursor when curwin is a hidden floating window.
Show cursor after returning to a normal (non-hidden) window.
Problem:
Neovim disables a number of terminal modes when it exits, some of which
cause the terminal to send asynchronous events to Neovim. It's possible
that Neovim exits before the terminal has received and processed all of
the sequences to disable these modes, causing the terminal to emit one
of these asynchronous sequences after Neovim has already exited. If this
happens, then the sequence is received by the user's shell (or some
other program that is not Neovim).
Solution:
When Neovim exits, it now emits a Device Attributes request (DA1)
after disabling all of the different modes. When the terminal responds
to this request we know that it has already received all of our other
sequences disabling the other modes. At that point, it should not be
emitting any further asynchronous sequences. This means the process of
exiting Neovim is now asynchronous as well since it depends on receiving
the DA1 response from the terminal.
Problem: When iterating in reverse with {start} > {end} in
`nvim_buf_get_extmarks()`, marks that overlap {start} and are
greater than {end} are included in the return value twice.
Marks that overlap {end} and do not overlap {start} are not
not included in the return value at all. Marks are not
actually returned in a meaningful "traversal order".
Solution: Rather than actually iterating in reverse, (also possible but
requires convoluted conditions and would require fetching
overlapping marks for both the {start} and {end} position,
while still ending up with non-traversal ordered marks),
iterate normally and reverse the return value.
Problem:
Default 'statusline' is implemented in C and not representable as
a statusline expression. This makes it hard for user configs/plugins to
extend it.
Solution:
- Change the default 'statusline' slightly to a statusline expression.
- Remove the C implementation.
Problem: We allow setting 'cmdheight' to 0 with ext_messages enabled
since b72931e7. Enabling ext_messages with vim.ui_attach()
implicitly sets 'cmdheight' to 0 for BWC. When non-zero
'cmdheight' is wanted, this behavior make it unnecessarily
hard to keep track of the user configured value.
Solution: Add set_cmdheight to vim.ui_attach() opts table that can be
set to false to avoid setting 'cmdheight' to 0.
Useful to e.g. limit the height to the window height, avoiding unnecessary
work. Or to find out how many buffer lines beyond "start_row" take up a
certain number of logical lines (returned in "end_row" and "end_vcol").
Problem: too many strlen() calls in indent.c
Solution: refactor indent.c slightly and remove strlen() calls

- Only match valid predefined and option variables.
- Match scope dictionaries.
- Highlight scope prefixed variables as a scope dictionary accessor. The
vimVarScope syntax group can be linked to vimVar to disable this.
- Include support for Neovim-only predefined and option variables.
Temporary collateral damage - scope dictionaries match instead of keys
in dictionary literals.

- Simplify usage:
- Instead of `nvim -l src/gen/gen_lsp.lua gen` now just
run `./src/gen/gen_lsp.lua`
- Removed `--methods` and `--capabilities` options.
- Improved rendering code in various areas.
This change modifies gen_lsp.lua so alias types are generated for
various types of lsp methods to distinguish between notifications
and requests:
- vim.lsp.protocol.Method.ServerToClient.Request
- vim.lsp.protocol.Method.ServerToClient.Notification
- vim.lsp.protocol.Method.ClientToServer.Request
- vim.lsp.protocol.Method.ClientToServer.Notification
These types are then used instead of `string` where appropriate.
Problem: Duplicate check for preinsert effect, particularly for Ctrl_w
and Ctrl_U.
Solution: Remove the specific check for Ctrl_w and Ctrl_U to eliminate
redundancy (glepnir).

Problem:
vim.uv.os_setenv gets "stuck" per-key. #32550
Caused by the internal `envmap` cache. #7920
:echo $FOO <-- prints nothing
:lua vim.uv.os_setenv("FOO", "bar")
:echo $FOO <-- prints bar (as expected)
:lua vim.uv.os_setenv("FOO", "fizz")
:echo $FOO <-- prints bar, still (not expected. Should be "fizz")
:lua vim.uv.os_unsetenv("FOO")
:echo $FOO <-- prints bar, still (not expected. Should be nothing)
:lua vim.uv.os_setenv("FOO", "buzz")
:echo $FOO <-- prints bar, still (not expected. Should be "buzz")
Solution:
- Remove the `envmap` cache.
- Callers to `os_getenv` must free the result.
- Update all call-sites.
- Introduce `os_getenv_noalloc`.
- Extend `os_env_exists()` the `nonempty` parameter.
Problem:
When doing paste operation mouse code tries to figure out it it is
dealing with a multi-line register by calling yank_register_mline(),
which fetches register data and checks its type. Later the code calls
either do_put() or insert_reg() which fetch register data again. This is
unnoticeable when working with internal neovim registers, but starts
hurting when dealing with clipboards, especially remote one (forwarded X
or socket tunnel or similar).
Solution:
Change yank_register_mline() to also return pointer to the
register structure prepared for pasting, and insert_reg() to accept
such register pointer and use it if it is supplied. do_put() already
has support for accepting a register structure to be used for pasting.

Problem: During insert-mode completion, the most relevant match is often
the one closest to the cursor—frequently just above the current line.
However, both `<C-N>` and `<C-P>` tend to rank candidates from the
current buffer that appear above the cursor near the bottom of the
completion menu, rather than near the top. This ordering can feel
unintuitive, especially when `noselect` is active, as it doesn't
prioritize the most contextually relevant suggestions.
Solution: This change introduces a new sub-option value "nearest" for the
'completeopt' setting. When enabled, matches from the current buffer
are prioritized based on their proximity to the cursor position,
improving the relevance of suggestions during completion
(Girish Palya).
Key Details:
- Option: "nearest" added to 'completeopt'
- Applies to: Matches from the current buffer only
- Effect: Sorts completion candidates by their distance from the cursor
- Interaction with other options:
- Has no effect if the `fuzzy` option is also present
This feature is helpful especially when working within large buffers where
multiple similar matches may exist at different locations.
You can test this feature with auto-completion using the snippet below. Try it
in a large file like `vim/src/insexpand.c`, where you'll encounter many
potential matches. You'll notice that the popup menu now typically surfaces the
most relevant matches—those closest to the cursor—at the top. Sorting by
spatial proximity (i.e., contextual relevance) often produces more useful
matches than sorting purely by lexical distance ("fuzzy").
Another way to sort matches is by recency, using an LRU (Least Recently Used)
cache—essentially ranking candidates based on how recently they were used.
However, this is often overkill in practice, as spatial proximity (as provided
by the "nearest" option) is usually sufficient to surface the most relevant
matches.
```vim
set cot=menuone,popup,noselect,nearest inf
def SkipTextChangedIEvent(): string
# Suppress next event caused by <c-e> (or <c-n> when no matches found)
set eventignore+=TextChangedI
timer_start(1, (_) => {
set eventignore-=TextChangedI
})
return ''
enddef
autocmd TextChangedI * InsComplete()
def InsComplete()

SkipTextChangedIEvent()

Problem: When switching to another window or tab page while the
completion menu is active, the menu stays visible, although it
belongs to the previous window/tab page context (Evgeni
Chasnovski).
Solution: Track the window and tab page where completion started. Detect
changes in the main editing loop and cancel completion mode if
the current window or tab page differs from where completion
started.
