Problem: Unable to tell whether msg_history_show event is emitted for a
:messages or g< command.
Solution: Add "prev_cmd" argument that is set to true for g<.
Problems:
- Miss some entries in `vim_diff.txt` and `index.txt`.
- I want to learn about Vim register, but when I type `:h register`, it
shows sponsor information instead. Note that unlike Nvim, Vim has a
separate session for `*register*`
Solution:
- Add missing commands to `index.txt`, `vim_diff.txt`
- Remove tag `register` from `index.txt`
Problem: When using `/` or `?` in command-line mode with 'ignorecase' and
'smartcase' enabled, the completion menu could show items that
don't actually match any text in the buffer due to case mismatches
Solution: Instead of validating menu items only against the user-typed
pattern, the new logic also checks whether the completed item
matches actual buffer content. If needed, it retries the match
using a lowercased version of the candidate, respecting
smartcase semantics.

Problem: Test_termdebug_decimal_breakpoints() fails with List index out
of range, because when adding the second breakpoint, the
cursor is still on the very first line (a header include line)
and therefore gdb refuses to set the breakpoint with:
`msg="No compiled code for line 1 in file XTD_decimal.c"`
Solution: Run the program, so that it will break at the very first
defined breakpoint and then once we are in the program,
set further breakpoints

Problem:
The `nvim_get_keymap()` function is missing the `lhsrawalt` field in its response for mappings with an alternate key representation. This makes its return value inconsistent with its documented `maparg()`-like structure and its formal type definition.
Solution:
Corrects the `keymap_array` function to pass the alternate mapping keys (`current_maphash->m_alt->m_keys`) to `mapblock_fill_dict`. The argument responsible for this was previously hardcoded to `NULL`.
For example, for a mapping of `<C-x>`, the API will now correctly return both `lhsraw` (`<80><fc>^DX`) and `lhsrawalt` (the alternate form, e.g., `^X`).
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:
Coverity reports string null termination issue:
*** CID 569464: Memory - string handling (STRING_NULL)
/src/nvim/runtime.c: 1374 in ExpandRTDir_int()
1372 if (flags & DIP_START) {
1373 memcpy(tail - 15, "pack/*/start/*/", 15); // NOLINT
>>> CID 569464: Memory - string handling (STRING_NULL)
>>> Passing unterminated string "tail - 15" to "globpath", which expects a null-terminated string.
1374 globpath(p_pp, tail - 15, gap, glob_flags, expand_dirs);
Similar issues occur at lines 1376, 1381, and 1383 where memcpy()
constructs strings passed to globpath() without null termination.
Solution:
Replace dangerous pointer arithmetic and memcpy() with direct snprintf()
construction of complete search paths. This eliminates the need for
buffer reuse through pointer offsets and ensures all strings passed to
globpath() are properly null-terminated.

Problem: completion: can only complete from keyword characters
Solution: remove this restriction, allow completion functions when
called from i_CTRL-N/i_CTRL-P to be triggered from non-keyword
characters (Girish Palya)
Previously, functions specified in the `'complete'` option were
restricted to starting completion only from keyword characters (as
introduced in PR 17065). This change removes that restriction.
With this change, user-defined functions (e.g., `omnifunc`, `userfunc`)
used in `'complete'` can now initiate completion even when triggered
from non-keyword characters. This makes it easier to reuse existing
functions alongside other sources without having to consider whether the
cursor is on a keyword or non-keyword character, or worry about where
the replacement should begin (i.e., the `findstart=1` return value).
The logic for both the “collection” and “filtering” phases now fully
respects each source’s specified start column. This also extends to
fuzzy matching, making completions more predictable.
Internally, this builds on previously merged infrastructure that tracks
per-source metadata. This PR focuses on applying that metadata to
compute the leader string and insertion text appropriately for each
match.
Also, a memory corruption has been fixed in prepare_cpt_compl_funcs().

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&
