This has been possible in the "backend" for a while but
API was missing.
Followup: we will need a `details2=true` mode for `nvim_get_hl_id_by_name`
to return information in a way forward compatible with even further
enhancements.
Problem:
Incremental preview is not allowed on 'nomodifiable' buffers.
Solution:
- Allow preview on 'nomodifiable' buffers.
- Restore the 'modifiable' option in case the preview function changes it.
Problem: We want to keep track of the current message column, which is
done very rudimentary for ext_messages; only checking if the
message ends in a newline to reset the column, while computing
the entire cellwidth of the message, which may contain
(multiple) newlines not necessarily at the end (since 21718c6).
This introduced a noticeable delay for large messages (e.g. :=vim).
Solution: Calculate the cellwidth of the message after the last newline.
Use it to keep track of the current message column. This might
not be a functional change currently, since it only affects
messages with (multiple) newlines not at the end of a message,
which I don't think we emit internally, and msg_col is reset for
a new kind. It does fix the performance problem.
This was kept for a while as it was a useful short hand and initially
matched what highlights what actually properly implemented. But now
|vim.hl.range()| is a better high-level shorthand with full support for
native multi-line ranges.
Problem:
Calling `xstrdup` with a NULL pointer causes a SIGSEGV if `lua_tostring` returns
NULL in `nlua_luv_thread_common_cfpcall`.
Crash stack trace:
- `_platform_strlen` → `xstrdup` (memory.c:469)
- `nlua_luv_thread_common_cfpcall` (executor.c:281)
Solution:
Check if `lua_tostring` returns NULL and pass NULL to `event_create` to avoid the crash.
Problem: too many strlen() calls in screen.c
Solution: refactor screen.c and remove calls to strlen(),
verify that leadmultispace != NULL (John Marriott)

This commit adds basic support for the kitty keyboard protocol to
Neovim's builtin terminal. For now only the first mode ("Disambiguate
escape codes") is supported.
* refactor(options): generic expand and did_set callbacks
Problem:
Many options have similar callbacks to check the values are valid.
Solution:
Generalize these callbacks into a single function that reads the option
table.
* refactor: gen_options.lua
refactor: gen_options.lua - inline get_cond
* refactor(options): use a simpler format for the common default

Problem: If a (vim.ui_attach) cmdline_hide callback triggers a redraw,
it may cause cmdline_show events for an already exited cmdline.
Solution: Avoid emitting cmdline_show event when ccline.cmdbuff is
already NULL. Unset ccline.cmdbuff before emitting cmdline_hide.
Problem: Coverity complains about dereferencing NULL value
Solution: Check that cms2 is not null

On master (and also before #31539) closing a window could cause the
used wininfo for a buffer to change. This is due to always removing the
previous NULL wininfo when deleting a window, even if that wininfo had
higher priority than the the deleted window's own wininfo.
Instead delete the wininfo with lowest priority. This retains the memory
saving efect while not affecting the effective value of window options
and so on.
Problem: Anchoring a floating window to the tabline and laststatus is
cumbersome; requiring autocommands and looping over all
windows/tabpages.
Solution: Add new "tabline" and "laststatus" options to the `relative`
field of nvim_open_win() to place a window relative to.
Problem: It was decided on Matrix chat that multitype options won't be necessary for Neovim options, and that options should only have a single canonical type. Therefore the code for supporting multitype options is unnecessary.
Solution: Remove the additional code that's used to provide multitype option support.
Problem:
Whether an option is allowed to be empty isn't well defined and
isn't properly checked.
Solution:
- For non-list string options, explicitly check the option value
if it is empty.
- Annotate non-list string options that can accept an empty value.
- Adjust command completion to ignore the empty value.
- Render values in Lua meta files
The code represents a useful pattern in normal mode where remapping
`<tab>` will implicitly also remap `<c-i>` unless you remap that
explicitly. This relies on the _unmapped_ behavior being identical which
is not true in terminal mode, as vterm can distinguish these keys.
Vim seems to entangle this with kitty keyboard mode detection which
is irrelevant for us. Conditional fallbacks depending on
keyboard mode could be done completely inside `vterm/` without getchar.c
getting involved, I would think.
Problem: Popup menu internal error with some abbr in completion item.
Solution: Don't compute attributes when there is no corresponding text.
Reduce indent in pum_redraw() while at it (zeertzjq).

**Problem:** Parsing can be slow for large files, and it is a blocking
operation which can be disruptive and annoying.
**Solution:** Provide a function for asynchronous parsing, which accepts
a callback to be run after parsing completes.

Problem: Assert hit related to message kind, which is reset after a
ext_messages UI is forcibly detached, so the assertion is
expectedly false. Assert hit related to message grid variables
after an ext_messages UI attaches while message grid is scrolled.
Solution: Don't check message kind assertion if no ext_messages UI is
attached. Flush message grid when first/last ext_messages UI
attaches/detaches.
Problem:
The `nvim_notify` API (note: unrelated to `vim.notify()` Lua API) was
not given any real motivation in https://github.com/neovim/neovim/pull/13843
There are, and were, idiomatic and ergonomic alternatives already.
Solution:
Deprecate `nvim_notify`.
