Problem:
virtual_text diagnostics are great when skimming a file, and
virtual_lines are great when "zooming in" on a particular problem.
Having both enabled results in duplicate diagnostics on-screen.
Solution:
This PR expands the behavior of `current_line` for virtual_text and
virtual_lines by making `virtual_text.current_line = false` distinct
from `nil`. If you set:
vim.diagnostic.config({
virtual_text = { current_line = false },
virtual_lines = { current_line = true },
})
With this configuration, virtual_text will be used to display
diagnostics until the cursor reaches the same line, at which point they
will be hidden and virtual_lines will take its place.
Problem:
enable() could be more flexible, so that it works even if called "late".
Solution:
- enable(true) calls `doautoall nvim.lsp.enable FileType`.
- enable(false) calls `client:stop()` on matching clients.
This will be useful for e.g. :LspStop/:LspStart also.
Problem:
Directories that are "trusted" by `vim.secure.read()`, are not detectable later
(they will prompt again). https://github.com/neovim/neovim/discussions/33587#discussioncomment-12925887
Solution:
`vim.secure.read()` returns `true` if the user trusts a directory.
Also fix other bugs:
- If `f:read('*a')` returns `nil`, we treat that as a successful read of
the file, and hash it. `f:read` returns `nil` for directories, but
it's also documented as returning `nil` "if it cannot read data with the
specified format". I reworked the implementation so we explicitly
treat directories differently. Rather than hashing `nil` to put in the
trust database, we now put "directory" in there explicitly*.
- `vim.secure.trust` (used by `:trust`) didn't actually work for
directories, as it would blindly read the contents of a netrw buffer
and hash it. Now it uses the same codepath as `vim.secure.read`, and
as a result, works correctly for directories.
Problem: UIs implementing ext_cmdline/message must also implement
ext_popupmenu in order to get cmdline completion with
wildoptions+=pum.
Solution: Allow marking a window as the ext_cmdline window through
nvim_open_win(), including prompt offset. Anchor the cmdline-
completion popupmenu to this window.

Problem:
`FileType` event is fired before checkhealth report is finished, so
user can't override report settings or contents.

Solution:
- Trigger FileType event later.
- Document how to remove emojis.
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:
Users of the Roslyn (C#) LSP have encountered significant delays when
retrieving pull diagnostics in large documents while using Neovim. For
instance, diagnostics in a 2000-line .cs file can take over 20 seconds
to display after edits in Neovim, whereas in VS Code, diagnostics for
the same file are displayed almost instantly.
As [mparq noted](https://github.com/seblj/roslyn.nvim/issues/93#issuecomment-2508940330)
in https://github.com/seblj/roslyn.nvim/issues/93, VS Code leverages
additional parameters specified in the [LSP documentation for
textDocument/diagnostic](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#documentDiagnosticParams),
specifically:
- previousResultId
- identifier
Solution:
When requesting diagnostics, Neovim should include the
`previousResultId` and `identifier` parameters as part of the request.
These parameters enable the server to utilize caching and return
incremental results.
Support for maintaining state is already present in the
[textDocument/semanticTokens implementation](8f84167c30/runtime/lua/vim/lsp/semantic_tokens.lua (L289)).
A similar mechanism can be implemented in `textDocument/diagnostic` handler.
Problem:
In cases when the (in-process) LSP server responds to the request
immediately and calls `notify_reply_callback` the request will still be
marked as pending, because the code assumes that the response will occur
asynchronously. Then the request will be pending forever, because it was
already set as "completed" before we even set it as "pending".
A workaround is to wrap `notify_replay_callback` in `vim.shedule` ([like
so](https://github.com/neovim/neovim/pull/24338#issuecomment-2809568617)]
but that seems counterintuitive.
Solution:
Handle this case in Client:request().
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):

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

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

endif
return arglead == '' ? allfiles : allfiles->matchfuzzy(arglead)

command! -nargs=* -complete=customlist,FuzzyBuffer Buffer execute('b '
.. selected_match->matchstr('\d\+'))
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:
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: Change applied in d3e495ce uses a byte-offset where a virtual
column is expected.
Solution: Set the cursor directly through a <Cmd> mapping, while making
sure the commands are ordered correctly by adding them to the
type-ahead buffer.
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: filetype: nroff detection can be improved
Solution: improve nroff detection (Eisuke Kawashima)

- do not try to detect alphabetically-sectioned files, except for n, as
nroff
- l: > 'l' happens to be a section for historical reasons

- n: e.g. /usr/share/man/mann/Tcl.n.gz
