Always allow the following four events to be nested, as they may contain
important information, and are triggered on the event loop, which may be
processed by a blocking call inside another autocommand.
- ChanInfo
- ChanOpen
- TermRequest
- TermResponse
There are some other events that are triggered on the event loop, but
they are mostly triggered by user actions in a UI client, and therefore
not very likely to happen during another autocommand, so leave them
unchanged for now.
Problem:
When a function like vim.wait() is used, we continuously drain the main
event queue until it is empty, never stopping for user input. This means
the libuv timer never runs and the terminal never gets refreshed, so
emit_termrequest continously reschedules itself onto the same event
queue, causing an infinite loop.
Solution:
Use a separate "pending" event queue, where events that require a
terminal refresh are temporarily placed. Drain this queue after a
terminal refresh and events are copied back onto the main queue. This
prevents infinite loops since the main event queue will always be able
to properly drain.
Problem: Skipping over a concealed line for which `win_line()`
_should_ be called because it has `virt_lines_above = false`
lines associated with it.
Solution: Don't include such a line in `wl_lastlnum` from the line
above.
Problem: terminal mode cursor refresh logic has too many edge cases where it
fails when events change curbuf.
Solution: change the logic. Introduce cursor_visible to TerminalState to more
reliably track if terminal mode has changed busy. Move visibility handling to
refresh_cursor and move its call in refresh_terminal to terminal_check to avoid
temporarily changed curbufs from influencing cursor state.
This has the effect of "debouncing" shape/visibility updates to once per
terminal state tick (with the final attributes taking effect, as expected). I
think this is OK, but as a result it may also be warranted to update when
redrawing during the same state tick (e.g: from events executing :redraw); this
can be added later, if wanted.
Also move previous tests to a more appropriate place.
Problem: tests: when the file 'TestCommand?Test' exists,
'Test_complete_cmdline()' will fail when writing the file. And
there's no related cleaning operation for this kind of file
before the test run.
Solution: modify `write` to `write!` to override (Jim Zhou).

Problem: heap-buffer-overflow with 'nostartofline' and Ex command in

Solution: Set cursor column when moving cursor to line 1 (zeertzjq).

When a plugin registers a TermRequest handler there is currently no way
for the handler to know where the terminal's cursor position was when
the sequence was received. This is often useful information, e.g. for
OSC 133 sequences which are used to annotate shell prompts.
Modify the event data for the TermRequest autocommand to be a table
instead of just a string. The "sequence" field of the table contains the
sequence string and the "cursor" field contains the cursor
position when the sequence was received.
To maintain consistency between TermRequest and TermResponse (and to
future proof the latter), TermResponse's event data is also updated to
be a table with a "sequence" field.
BREAKING CHANGE: event data for TermRequest and TermResponse is now a
table
Problem: wildmenu highlighting in popup can be improved
Solution: Check if the completion items contain submatches of the
entered text (Girish Palya).
This update enables highlighting in the popup menu even when the matched
fragment or pattern appears within an item (string) rather than only at the
beginning. This is especially useful for custom completion, where menu items
may not always start with the typed pattern.
For specific use cases, refer to the two examples in
https://github.com/vim/vim/pull/16759
A sliding window approach is used with direct string comparison. Performance
is not a concern, as highlighting is applied only to displayed lines, even if
the menu list is arbitrarily long.

Problem: Last line in a window does not store correct `wl_lastlnum` if
lines below it are concealed (resulting in e.g. incorrect
cursor row).
Solution: Increment `wl_lastlnum` while it points to a line above a
concealed line.
Problem: After 47aaddfa the max_height option is no longer respected.
Hover documentation and Signature help windows take up the
entire text height.
Solution: Compare to window's current height and only modify the height
if it would reduce the height, not enlarge it.
When multiple diagnostics appear on a single line, the virtual lines for
all diagnostics except the first were rendered with progressively fewer
columns.
Problem: mark '] wrong after copying text object (ubaldot)
Solution: Adjust position of '] for non-linewise, exclusive motions

Problem: command-line auto-completion hard with wildmenu
Solution: implement "noselect" wildoption value (Girish Palya)
When `noselect` is present in `wildmode` and 'wildmenu' is enabled, the
completion menu appears without pre-selecting the first item.
This change makes it easier to implement command-line auto-completion,
where the menu dynamically appears as characters are typed, and `<Tab>`
can be used to manually select an item. This can be achieved by
leveraging the `CmdlineChanged` event to insert `wildchar(m)`,
triggering completion menu.
Without this change, auto-completion using the 'wildmenu' mechanism is
not feasible, as it automatically inserts the first match, preventing
dynamic selection.
The following Vimscript snippet demonstrates how to configure
auto-completion using `noselect`:
```vim
vim9script
set wim=noselect:lastused,full wop=pum wcm=<C-@> wmnu
autocmd CmdlineChanged : timer_start(0, function(CmdComplete, [getcmdline()]))
def CmdComplete(cur_cmdline: string, timer: number)
var [cmdline, curpos] = [getcmdline(), getcmdpos()]
if cur_cmdline ==# cmdline # Avoid completing each character in keymaps and pasted text
&& !pumvisible() && curpos == cmdline->len() + 1
if cmdline[curpos - 2] =~ '[\w*/:]' # Reduce noise by completing only selected characters
feedkeys("\<C-@>", "ti")
set eventignore+=CmdlineChanged # Suppress redundant completion attempts
timer_start(0, (_) => {
getcmdline()->substitute('\%x00$', '', '')->setcmdline() # Remove <C-@> if no completion items exist
set eventignore-=CmdlineChanged
})
endif
endif
enddef
```

Problem: Cannot use "g<" mapping with ext_messages. Mapping displays
the scrollback buffer since the last command, but the
scrollback buffer is not populated with ext_messages.
Solution: With ext_messages; store messages in the history that otherwise
wouldn't be. Mark them as temporary messages to be deleted when
the scrollback buffer would be cleared. To this end, make the
message history a doubly-linked list such that messages can be
removed from an arbitrary position.
Outlook: Default ext_messages UI might not show the hit-enter prompt
so we want "g<" to work as a recommended way to show messages
for the last command (prompted by an indicator).
Problem: Vim's diff block merging algorithm when doing a multi-file diff
is buggy when two different diff hunks overlap a single
existing diff block (after v9.1.0743)
Solution: fix a couple bugs in this logic:
1. Fix regression from v9.1.0743 where it's not correctly expanding the
2nd overlap correctly, where it always expands without taking into
account that this was always taken care of when the first overlap
happened. Instead, we should only grow the 2nd overlap if it overhangs
outside the existing diff block, and if we encounter a new overlapping
diff block (due to overlap chaining).
2. When we expand a diff block to match the hunk size on the orig side
(when handling the first overlap), we expand the same amount of lines
in the new side. This is not sound if there exists a second overlap
hunk that we haven't processed yet, and that hunk has different
number of lines in orig/new. Fix this by doing the corresponding
counter adjustment when handling 2nd/3rd/etc overlap by calculating
the difference in lines between orig and new side.

**Problem:** Some weird languages have different comment syntax
depending on the location in the code, and we do not have a way to
determine the correct `commentstring` for these special cases.
**Solution:** Allow queries to specify `commentstring` values in
metadata, allowing users/`nvim-treesitter` to provide a better
commenting experience without hugely increasing the scope of the code in
core.

Problem: The 'preinsert' feature requires Ctrl-Y to confirm insertion,
but Ctrl-Y only works when the popup menu (pum) is displayed.
Without enforcing this dependency, it could lead to confusing
behavior or non-functional features.
Solution: Modify ins_compl_has_preinsert() to check for both 'menu' and
'menuone' flags when 'preinsert' is set. Update documentation
to clarify this requirement. This avoids adding complex
conditional behaviors. (glepnir)

Problem: _on_conceal_line callbacks are not invoked if callback has not
let Nvim know it wants to receive them. But this may change on
factors other than what is currently checked (changed buffer).
Solution: Forego this optimization, callback is still guarded behind
'conceallevel'.
Problem: ":so" command may read after end of buffer.
Solution: Compute length of text properly.
