**Problem:** Currently, parsing is asynchronous, but it involves a
(sometimes lengthy) step which finds all injection ranges for a tree by
iterating over that language's injection queries. This causes edits in
large files to be extremely slow, and also causes a long stutter during
the initial parse of a large file.
**Solution:** Break up the injection query iteration over multiple event
loop iterations.
The new native commenting functionality is currently not used when
editing mail. One could reasonably expect it to change the "quote" state
of any given line in the mail (i.e. the preceding ">"), which would be
very handy and feel natural when editing mail. Especially since the
current file already uses "setlocal comments+=n:>".
Solution: Add commentstring to `> %s` to be used in files of type mail.

Problem: No kind for `:registers/autocmd/augroup` messages. `:registers`
chunks are emitted as separate `msg_show` events.
Solution: Add the `list_cmd` kind to the message. Introduce a new
`msg_ext_skip_flush` variable to set to true around a
group of to be paired message chunks.
Problem: No test for 'listchars' "precedes" with double-width char.
Solution: Add a test and fix a typo in code (zeertzjq).

Cherry-pick test_listchars.vim changes from patch 9.0.0625.
Fix a regression from #30014 by moving the mb_schar assignment after the
double-width check.
Problem: Messages preceding a `cmdline_show->prompt` event can not be
distinguished as such when receiving the event. (But since
`msg_show` handlers should be scheduled, one can already check
whether a prompt is active when displaying the message.)
Solution: Rather than add a new kind again, use the `confirm` kind.
Could be seen as slightly misleading where it is more of
a choice rather than a confirmation, but that already applies
to `confirm()` as well...
PuTTY sets TERM=xterm, but sends ESC[1~ and ESC[4~ for Home/End keys,
which does not match what the 'xterm' terminfo has for khome/kend, so
libtermkeys instead reports them as the original DEC VT220 names.
The VT220 came with a DEC LK201 keyboard which had the following keys in
the area above arrow keys (where PCs now have Ins/Del/Home/End/etc):
┌────────┬────────┬────────┐
│ Find │ Insert │ Re- │
│ │ Here │ move │
├────────┼────────┼────────┤
│ Select │ Prev │ Next │
│ │ Screen │ Screen │
└────────┴────────┴────────┘
These would send ESC[x~ sequences in the expected order:
┌────────┬────────┬────────┐
│ ESC[1~ │ ESC[2~ │ ESC[3~ │
├────────┼────────┼────────┤
│ ESC[4~ │ ESC[5~ │ ESC[6~ │
└────────┴────────┴────────┘
Modern terminals continue to use the same sequences for Ins/Del as well
as PageUp/PageDn. But the VT220 keyboard apparently had no Home/End, and
PuTTY apparently chose to re-purpose the Find/Select key sequences for
Home/End (even though it claims to emulate Xterm and this doesn't match
what actual Xterm does).
So when Home/End are used in Neovim through PuTTY with TERM=xterm (the
default setting), libtermkey finds no match for the received sequences
in the terminfo database and defaults to reporting them as <Find> and
<Select> respectively.
PuTTY is not unique here -- tmux *also* sends ESC[1~ and ESC[4~ after
its internal translation -- but the difference is that 'tmux' terminfo
correctly maps them to Home/End so Neovim recognizes them as such, while
PuTTY defaults to using 'xterm' which uses a different mapping.
This initial patch only allows Neovim to recognize <Find> and <Select>
key codes as themselves, so that the user could manually map them e.g.
using ":imap <Find> <Home>".
Alternatives:
- Using TERM=putty(-256color) would of course be the most correct
solution, but in practice it leads to other minor issues, e.g. the
need to have different PuTTY config profiles for older or non-Linux
systems that lack that terminfo, or tmux's insistence on rendering
italics as reverse.
- Using Neovim through tmux avoids the problem (as tmux recognizes
ESC[1~ on input), but is something that needs to be manually run
every time.
The keycodes.h constants are slightly misnamed because K_SELECT was
already taken for a different purpose.
**Problem:** An erroneous query in the treesitter highlighter gives a
deluge of errors that makes the editor almost unusable.
**Solution:** Detach the highlighter after an error is detected, so that
it only gets displayed once (per highlighter instance).
Problem: Computing fold levels for an empty buffer (somehow) breaks the
parser state, resulting in a broken highlighter and foldexpr.
Cached foldexpr parser is invalid after filetype has changed.
Solution: Avoid computing fold levels for empty buffer.
Clear cached foldinfos upon `FileType`.
Problem: `vim.treesitter._create_parser()` silently loads the buffer,
bypassing the swapfile prompt.
Solution: Error for an unloaded buffer, ensure buffer is loaded in
`vim.treesitter.start()` instead.
Problem: after #32458, it may still be possible for `busy_start` UI events to be
emitted without matching `busy_stop`s in the terminal.
Solution: do `terminal_enter`'s cursor visibility check immediately after
setting/restoring State so it occurs before events. This ensures that if pending
escape sequences are processed while in `terminal_enter`, the cursor's initial
visibility is set before `is_focused` is checked by `term_settermprop`.
As a result, we can move the call to `showmode` back to where it was originally.
Problem: This keyword is used by GCC and Clang to prevent -Wpedantic
(and other options) from emitting warnings for many GNU C extensions.
This is used heavily in Alpine Linux through musl libc and
foritfy-headers. Without filtering the __extension__ keyword some type
definitions are duplicated. For example, timeval is defined once as
struct timeval { time_t tv_sec; suseconds_t tv_usec; };
and once as:
__extension__ struct timeval { time_t tv_sec; suseconds_t tv_usec; };
Without this patch, the LuaJIT C parser doesn't recognize that these
definitions are equivalent, causing unit test to fail on Alpine Linux.
Solution: Filter out the keyword in filter_complex_blocks.
We need to add a separate variable to keep track of this information,
since we cannot read the length of the valid regions table itself, since
it has holes.
Problem:
on_proc_exit() has a special-case that assumes that the UI client will
never spawn more than 1 child process.
Solution:
If the Nvim server exits, the stream EOF will trigger `rpc_close()` in
the UI client, so we don't need the special case in `on_proc_exit`.
Pass `Channel.exit_status` from `rpc_close()` so that the correct exit
code is reflected.
Problem: `showmode` in `terminal_enter` may cause `vpeekc` to process events,
which may handle pending escape sequences. If `CSI ? 25 l` is handled to hide
the cursor, it may remain hidden even after leaving terminal mode if both
`terminal_enter` and (indirectly) `showmode` call `ui_busy_start`, as there is
only one matching call to `ui_busy_stop` after leaving terminal mode.
Solution: let `terminal_enter` handle setting the initial visibility of the
cursor before calling `showmode`.
Closes#32456.
This simple solution assumes it isn't possible for e.g. `os_breakcheck` to be
called indirectly by something else before `terminal_enter` initially handles
cursor visibility and after it restores it, which I think is true.
