Problem:
`vim.version.intersect()` returns tables with `VersionRange` (method
table) as their metatable. Although the calculated bounds are correct,
the results do not expose `VersionRange` methods.
Solution:
Construct intersection tables with `range_mt`, matching
`vim.version.range()`. Add assertions covering method access and
repeated intersection.
Problem:
`compute_hash()` reconstructs buffer contents with `fileformat` set to
`mac` using CRLF (`dos`) line endings. The resulting hash does not match
the file's bytes.
Solution:
Define the line ending for every supported file format. Use that mapping
when reconstructing buffer contents for hashing.
Problem:
When disabling, the loader list is traversed forwards while entries are
removed. As a result, some entries are skipped and remain active. Thus,
disabling `vim.loader` restores `_G.loadfile`, but does not fully
restore the original package loader chain.
Solution:
Traverse `package.loaders` in reverse when removing cached loaders.
Capture the original `package.loaders` list in the test, and assert that
the list is restored properly.
Problem:
Fallback pynvim version lookup is broken since Vimscript-to-Lua rewrite.
- `vim.fs.basename()` returns the module filename instead of the
directory needed to discover adjacent metadata. This produces an
empty metadata list, hiding the remaining issues.
- `table.sort()` requires a Boolean comparator, while
`vim.version.cmp()` returns a number.
- `table.sort()` sorts in place and returns no value, so assigning its
result discards the metadata list.
Solution:
- Use `vim.fs.dirname()` to discover adjacent package metadata.
- Use `vim.version.gt()` as the descending Boolean comparator.
- Sort the metadata list in place.
This restores fallback version detection when `neovim.VERSION` is
unavailable.
Problem:
Coordinates-to-position conversion for the finish column in
`vim.hl.range()` checks the start column. This results in an incorrect
finish column when only one of the column coordinates is `vim.v.maxcol`.
Solution:
Check the finish column when converting the finish position. Update the
existing screen test so that a `vim.v.maxcol` finish highlights the
end-of-line marker, matching the existing `-1` behavior.
Problem: With 'wildmode' set to list:full the matches are listed but the
wildmenu is not shown, although it is "full" that starts
wildmenu mode (zeertzjq).
Solution: List the matches and show the menu, as the two behaviors in
the same phase ask for. The menu is left to the phases that
ask for it, so that "list" on its own still only lists

Other (squashed) commits:
fix(tui): emit ui_send output atomically with the frame
Problem:
tui_ui_send() writes directly to the TTY, bypassing the output buffer.
Sequences sent via nvim_ui_send() (e.g. kitty multiple-cursors, or
visual-dot-repeat) always arrive in a separate TTY write from the frame
they were computed for. This manifests as "tearing", or e.g. in the case
of multicursor the terminal renders text with stale cursor overlays.
Solution:
- tui_ui_send(): while a frame is being assembled (pending invalid
regions or buffered output), buffer instead of writing directly.
- Out-of-frame sends (tty queries, clear-on-disable) still write
immediately.
- mcursor.lua: emit the terminal-cursor update at the end of the redraw
cycle (`on_end`, when screen positions are final) instead of
vim.schedule().
Problem: options related to ui2 (like `fillchars` with `msgsep`) do not
take effect if set during startup after enabling ui2.
Solution: explicitly check just after startup if relevant options were
changed during startup.
Problem:
Folding range markers are overwritten while ranges are evaluated. A range ending on a row can hide another range starting there, and multiple nested ranges ending together emit only the innermost ending level.
Solution:
Track starts and the number of ends per row before emitting markers. Prefer starts on shared boundary rows and use the outermost level when nested ranges end together.

Problem:
Confirming cmdwin with a UTF-8 character containing 0x80 does not complete the
command.
Solution:
Escape K_SPECIAL bytes while feeding the cmdwin input after confirmation.
Problem:
The cmdline_hide callback causes an unnecessary cursor move to the cmdline,
before the normal redraw updates the cursor back to the current window. This
appears as "flicker" when using plugins such as matchit (legacy ":" mappings
instead of "<cmd>" mappings).
Solution:
Skip the immediate redraw for cmdline_hide events. The normal redraw
still updates the cursor after the cmdline window is hidden.
Problem:
If a snippet does not have a placeholder, we use insert mode instead of
select mode. From here <Esc> leaves the session and highlight active.
Solution:
Cancel the session on <Esc>.
Problem:
When 'cmdheight' is 0, the MsgSeparator can obscure the statusline when
a message is displayed, making its contents disappear until
the next redraw.
Solution:
Skip the separator when 'cmdheight=0' available.
Problem:
A blank line before the Content-Length header makes header parsing
fail with "Content-Length not found in header". An LF in the 'name'
state falls through to the 'invalid' state, which only return to
'name' at the *next* LF. That LF terminates the next line, so the
line with Content-Length is swallowed.
The same issue happens when a junk line is a partial match of the
header name (e.g. "Cont\nContent-Length: ...").
Solution:
When seeing an LF in the 'name' state, reset the cursor and stay in
'name' rather than entering 'invalid'.
Problem:
`nlua_pcall()` references `_G.debug.traceback`. If user code deletes it
or breaks it some other way, various Lua features are broken.
_G.debug = nil
vim.schedule(function() end)
vim.wait(100)
E5113: Lua chunk: attempt to index a nil value
stack traceback:
[C]: in function 'loop_poll'
[string "vim/_core/editor"]:176: in function 'wait'
crash.lua:3: in main chunk
PANIC: unprotected error in call to Lua API (attempt to index a nil value)
Solution:
Check `_G.debug.traceback` before using it as errfunc. If it's broken,
omit the traceback and say so in the error message.
Note: We could cache `_G.debug` in LUA_REGISTRYINDEX on startup, but
that would prevent plugins from providing custom functionality there
(and we happen to do so in `tui_spec.lua` for example).
Problem:
With these two lines (`\b` marking a backspace):
f\bfoo
xb\bb
line 1's bold run ends at byte 1 and line 2's begins at byte 1, so line 1
renders "fo" in bold rather than "f", and line 2's "b" is not bold at all.
Solution:
Only grow a highlight group that is on the current row.
Problem: A function used through 'omnifunc' or 'complete' is called the
same way whether 'autocomplete' started the completion or a
key asked for one, so it cannot answer differently.
Solution: Report which of the two it is in complete_info() as "auto". It
is returned only when asked for in {what}, so what
complete_info() says by itself does not change

Problem:
The vimdoc parser does not treat "\r" as whitespace, so in a CRLF
helpfile the codeblock rule fails and "*" pairs inside examples become
tags. On Windows this generates duplicate "." and "/" tags:
D:/a/neovim/neovim/build/bin/nvim.exe -u NONE -i NONE -e --headless -c "helptags ++t doc" -c "exe 'cquit' !empty(v:errmsg)""
Error in command line:
E154: Duplicate tag "." in gui.txt and repeat.txt
E154: Duplicate tag "/" in pattern.txt and usr_08.txt
E154: Duplicate tag "/" in usr_08.txt and pattern.txt
Note: The old C parser was unaffected because it read helpfiles in text
mode (`os_fopen(…, "r")`).
Solution:
Strip "\r" before parsing.
Problem:
Parent commit regressed some behavior of the old C helptags-gen impl:
- helpfiles in sub-directories are named by basename, so :help fails
- "help-tags" always names "tags", never "tags-nl"
- E150 E151 E152 E153 are never reported
- existing tags file is not overwritten if no tags were found
- a duplicate tag aborts the run, skipping the remaining directories
- `*.TXT` and `*.FRX` (uppercase) are not recognized as helpfiles
- tree-sitter-vimdoc accepts tags that the C parser rejected: `*a|b*`
(breaks |links|) and unterminated `*tag`
- PUC Lua "<" compares with (localized) `strcoll()`, so the tags file is
not sorted by byte value (E432)
- requiring `vim.treesitter` at load time breaks :help itself, not just
:helptags, where the module is unavailable
- `vim.pack` runs :helptags for plugins that have no "doc/" directory,
so every install/update emits E150
Solution:
- Fail the build if generating helptags reports any `v:errmsg`.
- Restore old behavior: tags generated for runtime/doc are now identical
to those from the C implementation. Errors are non-fatal messages
instead of exceptions, so all directories are still processed.
- Load treesitter lazily, report a plain error if parser is missing.
Problem:
Tags are manually parsed in C which is not flexible and prone to errors.
Extending the help system to allow for other formats (e.g. Markdown)
would require a large rewrite in the C core, while with Treesitter it
only needs a query update.
Solution:
Use the power of treesitter to extract the tags from helpfiles.
- build: set `$VIMRUNTIME` when generating helptags, like
`cmake/Util.cmake` already does for other generators.
- fix(help): only accept tags delimited by whitespace. The old C parser
only accepted a `*tag*` preceded by start-of-line or whitespace and
followed by whitespace or end-of-line. The vimdoc parser also captures
tags followed by other text, e.g. `*$XDG_STATE_HOME*/.../logs` in
starting.txt, which caused an E154 duplicate tag error for docs that
were previously fine.
Problem:
In order for ui2 to graduate to the main "messages ui" its configuration
needs to graduate into actual options.
Solution:
Migrate some of its config to 'messagesopt':
- "maxheight" (note: currently this is an integer treated as
a "percentage"; if we want to support a row count we could allow
values with units, like `"42%"`)
- "pager"
- "timeout"
Also improves error messages:
messagesopt=hit-enter,history:500,bogus E474: Unknown item 'bogus'
messagesopt=hit-enter,history:500,progress:x E474: 'progress' must be one of: , c
messagesopt=hit-enter,history:abc E474: 'history' requires a number
Problem:
`pager_char` compares the `keytrans()` result exactly. E.g. `pager_char
= "<cr>"` does not work, it expects `<CR>` (uppercase).
Solution:
Normalize `pager_char` in enable().
Problem:
`Completor:accept()` applies the item against the range the server
answered with. Characters typed after the request but before accepting
lie inside neither that range nor the replacement, so they are left
behind by the insertion: typing `a` after `foob` and accepting `foobar`
within the 200 ms debounce yields `foobara`.
Solution:
Grow the item's range over the characters typed since the request, so
that `accept()` replaces them. Only while the candidate still matches,
decided by the longest common prefix `show()` already computes, so input
that contradicts it is left alone. Snippet items are unaffected, since
`accept()` ignores the range for them.
Problem:
`vim.on_key()` callbacks are invoked for keys that `getchar()` consumes,
which never reach the main loop, and there is no way to tell such a key
apart. With ui2 the `on_key` handler activated after interactive
cmdline, handles it as `pager_char` (thus enters the ui2 pager).
Solution:
Skip `vim.on_key()` callbacks during `getchar()`/`getcharstr()`.
Problem:
`Completor:accept()` hands the item's range straight to
`nvim_buf_set_text()`. That range is resolved when the response arrives,
so text deleted before accepting (backspacing within the 200 ms
debounce) leaves the range end past what is left of the line, and the
accept aborts with `Invalid 'end_col': out of range`.
18d6436 fixed the same staleness in `Completor:show()`, which drops an
item once its range *start* falls outside the buffer. That guard does
not cover the range end, and `accept()` was never given one, so this is
a hole left by that fix rather than a regression of it.
Solution:
Clamp the end of the range to the end of the line before writing. The
start needs no clamp: `show()` dropped the item one event loop tick
earlier if it had gone out of range.
Problem:
One item with an edit range before the word boundary changes the start
column for all items. For tsserver `str.`, completing `str.char` can
become `strcharAt` and break filtering.
Solution:
Prepend the missing text and filter on it.
Problem: complete_info() omits "abbr_hlgroup" and "kind_hlgroup".
Solution: Keep the highlight group ID with the match instead of the
resolved attribute and add both entries to the returned items
(glepnir).

1) The complete example plugin at :h write-plugin the end of the
documentation didn't reflect the snippets provided during the
tutorial. In most of the Add() function, interpolated strings are
used, but the final result used concatenated strings.
2) The example provided in readdir() to get a list of files ending in
".txt" didn't properly escape the dot in the regular expression:
readdir(dirname, {n -> n =~ '.txt$'})
This would match any file ending with "txt" that is at least 4
characters long, instead it should be:
readdir(dirname, {n -> n =~ '\.txt$'})

Problem:
Mapped keys can produce on_key callbacks with an empty `typed` value.
so mapped motions such as `j -> gj` are not recognized as typed input
and do not dismiss messages
Solution:
Track whether an empty `typed` callback follows typed input, allowing
mapped motions to dismiss messages like directly typed motions.
Problem:
CTRL-] via lsp tagfunc passes URI paths through :tag, which expands
\$VAR, so files like people_.\$personId.tsx fail with E429.
Solution:
fnameescape() the filename in tag items so \$ is treated as literal.
Problem:
man -w echoes any existent file back unchanged. :Man rejected all such
paths, so :Man /usr/share/man/man1/bash.1 failed even for real man pages.
Solution:
Accept an echoed path when it looks like a man page (.../man1/foo.1).
Problem:
A mapping that ends mid-operation (`nnoremap ,D d`) emits a content-free
"mapping" atom plus a `pending` field, and the "continuation" motion
arrives as a sibling atom. Consumers must stitch the two together (which
has broken cases, e.g. Insert-opening mappings (",i") lose their session
entirely).
- ",i": the session atom is dropped bc the mapping RHS is consumed
before the session starts (typebuf_maplen()==0), so
atom_is_user_input()=false.
- ":normal"-in-opfunc: the opfunc internal "v..y" session (a) became
kVatomTyped just because the deferred composite was open, masking the
real operator capture via atom_captures, and (b) its nested frames
re-derived the outer redo.
- "Motion" based on `moved=true`, has false negatives.
- `CmdAtom.remap` is unnecessary, and clutters the docs/usage.
Solution:
- Introduce `frame_id` to identify CmdFrames.
- Classify `type=motion` better, via `NV_MOTION` flag on the `nv_cmds` table.
- Drop `CmdAtom.pending`, `CmdAtom.remap`.
- Defer atom_composite_end() at the clock edge while an operator is
pending, Visual is active, or `restart_edit` is set: the composite
keeps collecting, so the continuation is captured in the mapping atom.
- ",i": Now an open composite counts as user input.
- ":normal"-in-opfunc: Now handled correctly.
- `remap` is now decided by `composite.payload || 0 subatoms`.
atom_payload_mark() records the read the resolution never captures.
- `toplevel` is now decided by `CmdFrame.parent == NULL`.

Problem:
On Windows, vim.ui.open() passes URLs to `cmd.exe /c start`. cmd.exe
treats `&` as a command separator, so query strings are truncated.
Solution:
Caret-escape `&|<>^%!` in URIs when the open handler is cmd.exe.
Problem: wrong end_row when copying extmarks to the pager buffer when expanding
a message. Results in incorrect highlights or errors such as "invalid `end_col`
out of range".
Solution: don't forget to offset end_row by srow, as is already done for the
copied lines and extmark rows.
Problem:
Empty string is falsy, so the spec's label fallback applies, but there only checks
for nil. An empty filterText drops the item, an empty sortText sorts it
first, and an empty insertText leaves the word empty.
Solution:
Treat empty string as unset.
Problem:
- `lhs` is not fully realized. E.g. for a "payload" mapping
`lhs` omits the `getchar()` payload during a mapping (vim-surround
`ds'` reports `lhs="ds"`). This means plugins like vim-repeat are
still needed...
- The "delta" fields of a CmdAtom are calculated too late.
- `<abuf>` and `changed` check whatever (wrong) buffer a command
(":bnext") might land in.
- CTRL-W_w between two windows on the same buffer reports type="motion".
Solution:
- `CmdOrigin` samples (buf/win/cursor/changedtick) at each "scope" entry
(CmdFrame, composite, Visual session, insert session).
- `dd<C-w>l` reports `changed=true` for the buffer it edited, regardless
of where the cursor ends up.
- New fields:
- `pos`: cursor position at command start.
- `moved`: indicates whether the cursor moved (in same buffer).
- `undoseq`: undo state at settlement.
- lhs now includes the payload: "ds)" reports lhs="ds)" instead of "ds".
- Easy for users to "replay" any atom.
- Rename: type "command" => "normal", "ex" => "excmd"; `arg` => `cmdarg`
- Drop `cascade` field (no reason to expose it)
Remove the note about "this function is called only once per :find
command invocation".
