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&
```

The examples mention the [u] flag, so at least the [u] flag should be
introduced before the examples.
Slightly reword the sentence about trailing/leading white space.

Problem: File paths change from symlink to target path after :cd command
when editing files through symbolic links
Solution: Add "~" flag to 'cpoptions' to control symlink resolution.
When not included (default), symlinks are resolved maintaining
backward compatibility. When included, symlinks are preserved
providing the improved behavior. (glepnir)

Problem: String manipulation can be improved in cmdexpand.c
Solution: Refactor cmdexpand.c to remove calls to
STRLEN()/STRMOVE()/STRCAT() (John Marriott)
This commit does the following:
In function nextwild():
- slightly refactor the for loop to remove an array access
- call STRLEN() and store it's result for reuse
- move some variables closer to where they are used, renaming some on
the way
In function ExpandOne():
- move some calculations outside of the for loops
- factor out calls to STRCAT() (which has an inherent STRLEN() call) in
the for loop
- move some variables closer to where they are used
In function expand_files_and_dirs():
- factor out calls to STRMOVE() (which has an inherent STRLEN() call)
In function get_filetypecmd_arg():
- move declarations of the string arrays into the blocks where they are
used
In function get_breakadd_arg():
- move declaration of the string array into the block where it is
used
In function globpath():
- factor out calls to STRLEN() and STRCAT()
- move some variables closer to where they are used
And finally some minor cosmetic style changes

Make `vim.iter():take()` and `vim.iter():skip()`
optionally accept predicates to enable takewhile
and skipwhile patterns used in functional
programming.
I was initially trying to port several cmdline tests from Vim involving
test_override('char_avail') without having to rewrite entire tests in
Lua, but haven't figured out a good way achieve that yet. Nevertheless
emulating test_override('starting') is easier.
Problem:
The previous fix in #34314 relies on copying the tree in `tree_root` to
ensure the `TSNode`'s tree cannot be mutated. But that causes the
problem where two calls to `tree_root` return nodes from different
copies of a tree, which do not compare as equal. This has broken at
least one plugin.
Solution:
Make all `TSTree`s on the Lua side always immutable, avoiding the need
to copy the tree in `tree_root`, and make the only mutation point,
`tree_edit`, copy the tree instead.
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
