bcd5995b40 patch 9.1.1341: cannot define completion triggers
Problem:  Cannot define completion triggers and act upon it
Solution: add the new option 'isexpand' and add the complete_match()
          function to return the completion matches according to the
          'isexpand' setting (glepnir)

Currently, completion trigger position is determined solely by the
'iskeyword' pattern (\k\+$), which causes issues when users need
different completion behaviors - such as triggering after '/' for
comments or '.' for methods. Modifying 'iskeyword' to include these
characters has undesirable side effects on other Vim functionality that
relies on keyword definitions.

Introduce a new buffer-local option 'isexpand' that allows specifying
different completion triggers and add the complete_match() function that
finds the appropriate start column for completion based on these
triggers, scanning backwards from cursor position.

This separation of concerns allows customized completion behavior
without affecting iskeyword-dependent features. The option's
buffer-local nature enables per-filetype completion triggers.

031f2273cb patch 9.1.1339: missing out-of-memory checks for enc_to_utf16()/utf16_to_enc()
Problem:  missing out-of-memory checks for enc_to_utf16() and
          utf16_to_enc()
Solution: Add out-of-memory checks and fix a few other minor issues
          (John Marriott)

This change does:
-  add missing out-of-memory checks for enc_to_utf16() and
   utf16_to_enc()
-  add a small optimisation in mch_errmsg_c() and mch_msg_c() (in
   message.c) to only call STRLEN() if needed.
-  fix a memory leak in winpty_term_and_job_init() (in terminal.c).

92f68e26ec patch 9.1.1329: cannot get information about command line completion
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 #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}"' ..
       ' --exclude-dir=.git --exclude=".*" --exclude="tags" --exclude="*.swp"') : []
enddef
def VisitFile()
    if (selected_match != null_string)
        var qfitem = getqflist({lines: [selected_match]}).items[0]
        if qfitem->has_key('bufnr') && qfitem.lnum > 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)
        endif
    endif
enddef

        allfiles = systemlist($'find {get(g:, "fzfind_root", ".")} \! \(

    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.

0ac1eb3555 patch 9.1.1311: completion: not possible to limit number of matches
Problem:  completion: not possible to limit number of matches
Solution: allow to limit the matches for 'complete' sources by using the
          "{flag}^{limit}" notation (Girish Palya)

This change extends the 'complete'  option to support limiting the
number of matches returned from individual completion sources.

**Rationale:** In large files, certain sources (such as the current
buffer) can generate an overwhelming number of matches, which may cause
more relevant results from other sources (e.g., LSP or tags) to be
pushed out of view. By specifying per-source match limits, the
completion menu remains balanced and diverse, improving visibility and
relevance of suggestions.

A caret (`^`) followed by a number can be appended to a source flag to
specify the maximum number of matches for that source. For example:
```
  :set complete=.^9,w,u,t^5
```
In this configuration:
- The current buffer (`.`) will return up to 9 matches.
- The tag completion (`t`) will return up to 5 matches.
- Other sources (`w`, `u`) are not limited.

This feature is fully backward-compatible and does not affect behavior
when the `^count` suffix is not used.

The caret (`^`) was chosen as the delimiter because it is least likely
to appear in file names.

b156588eb7 patch 9.1.1308: completion: cannot order matches by distance to cursor
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()
    if getcharstr(1) == '' && getline('.')->strpart(0, col('.') - 1) =~ '\k$'
        SkipTextChangedIEvent()
        feedkeys("\<c-n>", "n")
    endif
enddef

inoremap <silent> <c-e> <c-r>=<SID>SkipTextChangedIEvent()<cr><c-e>

inoremap <silent><expr> <tab>   pumvisible() ? "\<c-n>" : "\<tab>"

cbe53191d0 patch 9.1.1301: completion: cannot configure completion functions with 'complete'
Problem:  completion: cannot configure completion functions with
          'complete'
Solution: add support for setting completion functions using the f and o
          flag for 'complete' (Girish Palya)

This change adds two new values to the `'complete'` (`'cpt'`) option:
- `f` – invokes the function specified by the `'completefunc'` option
- `f{func}` – invokes a specific function `{func}` (can be a string or `Funcref`)

These new flags extend keyword completion behavior (e.g., via `<C-N>` /
`<C-P>`) by allowing function-based sources to participate in standard keyword
completion.

**Key behaviors:**

- Multiple `f{func}` values can be specified, and all will be called in order.
- Functions should follow the interface defined in `:help complete-functions`.
- When using `f{func}`, escaping is required for spaces (with `\`) and commas
  (with `\\`) in `Funcref` names.
- If a function sets `'refresh'` to `'always'`, it will be re-invoked on every
  change to the input text. Otherwise, Vim will attempt to reuse and filter
  existing matches as the input changes, which matches the default behavior of
  other completion sources.
- Matches are inserted at the keyword boundary for consistency with other completion methods.
- If finding matches is time-consuming, `complete_check()` can be used to
  maintain responsiveness.
- Completion matches are gathered in the sequence defined by the `'cpt'`
  option, preserving source priority.

This feature increases flexibility of standard completion mechanism and may
reduce the need for external completion plugins for many users.

**Examples:**

Complete matches from [LSP](https://github.com/yegappan/lsp) client. Notice the use of `refresh: always` and `function()`.

```vim
set cpt+=ffunction("g:LspCompletor"\\,\ [5]). # maxitems = 5

def! g:LspCompletor(maxitems: number, findstart: number, base: string): any
    if findstart == 1
        return g:LspOmniFunc(findstart, base)
    endif
    return {words: g:LspOmniFunc(findstart, base)->slice(0, maxitems), refresh: 'always'}
enddef
autocmd VimEnter * g:LspOptionsSet({ autoComplete: false, omniComplete: true })
```

Complete matches from `:iabbrev`.

```vim
set cpt+=fAbbrevCompletor

def! g:AbbrevCompletor(findstart: number, base: string): any
    if findstart > 0
        var prefix = getline('.')->strpart(0, col('.') - 1)->matchstr('\S\+$')
        if prefix->empty()
            return -2
        endif
        return col('.') - prefix->len() - 1
    endif
    var lines = execute('ia', 'silent!')
    if lines =~? gettext('No abbreviation found')
        return v:none  # Suppresses warning message
    endif
    var items = []
    for line in lines->split("\n")
        var m = line->matchlist('\v^i\s+\zs(\S+)\s+(.*)$')
        if m->len() > 2 && m[1]->stridx(base) == 0
            items->add({ word: m[1], info: m[2], dup: 1 })
        endif
    endfor
    return items->empty() ? v:none :
        items->sort((v1, v2) => v1.word < v2.word ? -1 : v1.word ==# v2.word ? 0 : 1)
enddef
```

**Auto-completion:**

Vim's standard completion frequently checks for user input while searching for
new matches. It is responsive irrespective of file size. This makes it
well-suited for smooth auto-completion. You can try with above examples:

```vim
set cot=menuone,popup,noselect inf

autocmd TextChangedI * InsComplete()

def InsComplete()
    if getcharstr(1) == '' && getline('.')->strpart(0, col('.') - 1) =~ '\k$'
        SkipTextChangedIEvent()
        feedkeys("\<c-n>", "n")
    endif
enddef

inoremap <silent> <c-e> <c-r>=<SID>SkipTextChangedIEvent()<cr><c-e>

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
```
