Problem: tests: Test_xxd_color2() test failure dump diff is misleading
Solution: Ensure the reference dump and the test dump are both processed the
same (Drew Vogel).
Background:
Commit b6dc76b6fd23e571d309064b795847ee9ffc7689 sought to make the xxd
screendump tests compatible with non-standard `XXD` overrides. It provides a
vim script that matches a very general `xxd` command pattern but then also
removed the matching line from the reference dump. This second step was
unnecessary because `VerifyScreenDump()` runs the associated vim script against
both the reference dump and the test dump.
Problem Details:
As part of some unrelated work, the GUI tests were failing with a window size 1
column too narrow. The screendumps in `Test_xxd_color2` were failing as a
result. When I loaded the diff using `term_dumpdiff()` the associated vim
scripts are not run. As a result, the test dump contained the `xxd` invocation
on line 1 while reference dump did not. This throws the diff off, obscuring the
true issue of the GUI window being too narrow.
Verification:
In addition to the test suite, locally I've tried to recreate the issue being
fixed in b6dc76b6fd23e571d309064b795847ee9ffc7689. Setting a very non-standard
`XXD` path, this test still passes:
```
XXD=/home/dvogel/opt/vim/bin/xxd TEST_FILTER=Test_xxd_color2 TERM=xterm-color make test_xxd
rm -f test_xxd.res test.log messages starttime
if test -n "${ASAN_OPTIONS}"; then \
XXD=../xxd/xxd; export XXD; ASAN_OPTIONS="${ASAN_OPTIONS}_test_xxd" \
UBSAN_OPTIONS="${UBSAN_OPTIONS}_test_xxd" VIMRUNTIME=../../runtime ../vim -f \
-u unix.vim --gui-dialog-file guidialog -U NONE --noplugin --not-a-term -S \
runtest.vim test_xxd.vim ; \
fi

Problem: Shebang filetype detection can be improved
Solution: Improve detection logic (Eisuke Kawashima)
Vim does not correctly detect filetype from
- `#!/usr/bin/env --split-string=awk -f`
- `#!/usr/bin/env -S -i awk -f`
- `#!/usr/bin/env -S VAR= awk -f`
So update the current detection logic to detect those cases.

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.

Problem: missing out-of-memory checks for enc_to_utf16() and

This change does:
- add missing out-of-memory checks for enc_to_utf16() and

- 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).

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):

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)

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)

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.

E749 is given when :print (with any range) is issued on an empty buffer,
like the one you get with :new or :enew. Furthermore, due to Vi
compatibility :| is a synonym.
As a result, mappings intended to include a <bar> separator (esp. in the
case of boolean or "||") between commands can generate E749 on startup
when placed in a vimrc if the bars are not properly encoded or escaped.
[1]. Document this failure mode and synonym near the generated error,
and cross link with :help :bar. Note that one must read or scroll quite
a bit to find the mention of :| behaving like :print!
