Problem: Hardcoded highlight IDs for ext_messages/cmdline output need
to be adjusted everytime a builtin highlight group is added.
Solution: Store a global map of default highlights through nvim_get_hl()
and fetch missing (custom) highlight groups through synIDattr().
Use more compact formatting for screen:expect().
Problem: Unable to tell whether msg_history_show event is emitted for a
:messages or g< command.
Solution: Add "prev_cmd" argument that is set to true for g<.
Problem: ext_messages cannot tell when the screen was cleared, which is
needed to clear visible messages. An empty message is also
never emitted, but clears messages from the message grid.
Solution: Repurpose the "msg_clear" event to be emitted when the screen
was cleared. Emit an empty message with the `empty` kind to
hint to a UI to clear the cmdline area.
Problem: ext_messages is implemented to mimic the message grid
implementation w.r.t. scrolling messages, clearing scrolled
messages, hit-enter-prompts and replacing a previous message.
Meanwhile, an ext_messages UI may not be implemented in a way
where these events are wanted. Moreover, correctness of these
events even assuming a "scrolled message" implementation
depends on fragile "currently visible messages" global state,
which already isn't correct after a previous message was
supposed to have been overwritten (because that should not only
happen when `msg_scroll == false`).
Solution: - No longer attempt to keep track of the currently visible
messages: remove the `msg_ext(_history)_visible` variables.
UIs may remove messages pre-emptively (timer based), or never
show messages that don't fit a certain area in the first place.
- No longer emit the `msg(_history)_clear` events to clear
"scrolled" messages. This opens up the `msg_clear` event to
be emitted when messages should actually be cleared (e.g.
when the screen is cleared). May also be useful to emit before
the first message in an event loop cycle as a hint to the UI
that it is a new batch of messages (vim._extui currently
schedules an event to determine that).
- Set `replace_last` explicitly at the few callsites that want
this to be set to true to replace an incomplete status message.
- Don't store a "keep" message to be re-emitted.
Problem: No ext_messages kind for the :command, :version commands.
:version is emitted as multiple events.
Solution: Assign them the "list_cmd" kind. Use `msg_put*` to properly
format the message as a single event.
Problem: The "append" parameter added in abb40ece is missing from
history entries, resulting in different message formatting
for "g<".
Solution: Add "append" field to message history entries.

Problem: When using 'winblend', transparent backgrounds (-1) are forced
to default colors (usually black) during attribute blending, breaking
the transparency effect.
Solution: Check original background colors before blending in
hl_blend_attrs(). If both background and foreground originally had
transparent backgrounds, preserve transparency instead of forcing
default colors.
Problem: "msg_history_show" event is emitted when `msg_silent > 0`.
E.g. when capturing its output with `execute()`, which also
doesn't work with ext_messages.
Solution: Don't emit the "msg_history_show" event when `msg_silent > 0`.
Call regular messaging functions when `redirecting()`, to
execute `redir_write()` while ensuring the message itself
is not emitted.
Problem: not easily possible to complete from register content
Solution: add register-completion submode using i_CTRL-X_CTRL-R
(glepnir)

Problem: Unable to emit a message with arbitrary kind.
Solution: Add a "kind" opts field to nvim_echo().
Use it to set the "list_cmd" kind for vim.show_pos().
Problem: "99 searchcount ought to be enough for anyone."
Solution: Increase `SEARCH_STAT_DEF_MAX_COUNT` to 999, which I'm sure
will suffice for the next twenty years.

Problem: Consecutive "msg_show" events stemming from an `:echon`
command are supposed to be appended without a newline, this
information is not encoded in the "msg_show" event.
Solution: Add an "append" parameter to the "msg_show" event that is set
to true to indicate the message should not start on a new line.
Considered alternative: Emit a newline for the common case instead at the
start of a new message. That way UIs can more closely follow the logic
as it is implemented for the message grid currently. This would be a
breaking change. The "append" parameter seems OK.
Problem: Extui does not route messages emitted as a result of a typed
command to the "more" window.
Command message leading shell messages is missing a kind.
Messages not routed to 'cmdheight' area after it was 0.
Solution: Route messages that were emitted in the same event loop as an
entered command to the "more" window. Also append multiple
messages in an already open more-window.
Assign it the `shell_cmd` kind.
Change message position when 'cmdheight' changes from 0.
Problem: Messages that are already added to the history are not emitted
as part of the "g<" msg_history_show event.
Solution: Move clearing the history for temporary messages to before
adding a message to the history, rather than after emitting
a message.
Problem: Missing kind and separate event for each line for message
containing buffer lines for e.g. `:print`.
Solution: Set the `list_cmd` kind and only `msg_start()` for the first
message, print a newline instead.
Problem: Ruler is not cleared from the screen/ext_messages state when
it is no longer drawn after e.g. `set noruler` or when moving
from a floating to a regular window.
Solution: Remember if ruler was drawn and clear it.
Problem:
stderr messages from executing ":!cmd" show up with
highlight hl-ErrorMsg. But some shell utilites use stderr for debug
logging, progress updates, etc.
Solution:
Highlight shell command outputs hl-StderrMsg and hl-StdoutMsg.
Problem: 'showmode' ext_messages state is not cleared after insert_expand mode.
Solution: Replace empty message with more idiomatic way to clear the showmode.
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: Diff mode's inline highlighting is lackluster. It only
performs a line-by-line comparison, and calculates a single
shortest range within a line that could encompass all the
changes. In lines with multiple changes, or those that span
multiple lines, this approach tends to end up highlighting
much more than necessary.
Solution: Implement new inline highlighting modes by doing per-character
or per-word diff within the diff block, and highlight only the
relevant parts, add "inline:simple" to the defaults (which is
the old behaviour)
This change introduces a new diffopt option "inline:<type>". Setting to
"none" will disable all inline highlighting, "simple" (the default) will
use the old behavior, "char" / "word" will perform a character/word-wise
diff of the texts within each diff block and only highlight the
differences.
The new char/word inline diff only use the internal xdiff, and will
respect diff options such as algorithm choice, icase, and misc iwhite
options. indent-heuristics is always on to perform better sliding.
For character highlight, a post-process of the diff results is first
applied before we show the highlight. This is because a naive diff will
create a result with a lot of small diff chunks and gaps, due to the
repetitive nature of individual characters. The post-process is a
heuristic-based refinement that attempts to merge adjacent diff blocks
if they are separated by a short gap (1-3 characters), and can be
further tuned in the future for better results. This process results in
more characters than necessary being highlighted but overall less visual
noise.
For word highlight, always use first buffer's iskeyword definition.
Otherwise if each buffer has different iskeyword settings we would not
be able to group words properly.
The char/word diffing is always per-diff block, not per line, meaning
that changes that span multiple lines will show up correctly.
Added/removed newlines are not shown by default, but if the user has
'list' set (with "eol" listchar defined), the eol character will be be
highlighted correctly for the specific newline characters.
Also, add a new "DiffTextAdd" highlight group linked to "DiffText" by
default. It allows color schemes to use different colors for texts that
have been added within a line versus modified.
This doesn't interact with linematch perfectly currently. The linematch
feature splits up diff blocks into multiple smaller blocks for better
visual matching, which makes inline highlight less useful especially for
multi-line change (e.g. a line is broken into two lines). This could be
addressed in the future.
As a side change, this also removes the bounds checking introduced to
diff_read() as they were added to mask existing logic bugs that were
properly fixed in vim/vim#16768.

Problem: Message kind logic for emitting an error message is convoluted
and still results in emitting an unfinished message earlier than
wanted.
Solution: Ensure emsg_multiline() always sets the kind wanted by the caller
and doesn't isn't unset to logic for emitting the source message.
Caller is responsible for making sure multiple message chunks are
not emitted as multiple events by setting `msg_ext_skip_flush`...
Problem: Various list commands end in a newline to go to a new line on
the message grid for the prompt message, which is unwanted
with ext_messages.
Solution: Don't emit a trailing newline with ext_messages for
inputlist(), :tselect and z=.

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: 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: 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...
Problem: We want to deprecate `nvim_err_write(ln)()` but there is no
obvious replacement (from Lua). Meanwhile we already have
`nvim_echo()` with an `opts` argument.
Solution: Add `err` argument to `nvim_echo()` that directly maps to
`:echoerr`.
Problem: Message grid newline formatting based on `msg_col` is not
utilized with ext_messages.
Solution: Increment `msg_col` with the cell width of the chunk. Allowing
message code that uses `msg_col` to determine when to place a
newline to do so. E.g. when the message goes beyond `Columns`;
this is not necessarily where the ext_messages implementation
would want to place a newline, but it is a best guess. Message
parsing and manipulation is still possible.
Problem: Prompts are emitted as messages events, where cmdline events
are more appropriate. The user input is also emitted as
message events in fast context, so cannot be displayed with
vim.ui_attach().
Solution: Prompt for user input through cmdline prompts.
Problem: Unable to tell what highlight the prompt part of a
cmdline_show event should have, and whether cmdline_hide was
emitted after aborting.
Solution: Add additional arguments hl_id to cmdline_show, and abort to
cmdline_hide.
Problem:
`termopen` has long been a superficial wrapper around `jobstart`, and
has no real purpose. Also, `vim.system` and `nvim_open_term` presumably
will replace all features of `jobstart` and `termopen`, so centralizing
the logic will help with that.
Solution:
- Introduce `eval/deprecated.c`, where all deprecated eval funcs will live.
- Introduce "term" flag of `jobstart`.
- Deprecate `termopen`.
Also avoid going down message callstack with empty message, and remove expected grid for some tests where it did not change, and we are just testing for expected messages.
When a terminal application running inside the terminal emulator sets
the cursor shape or blink status of the cursor, update the cursor in the
parent terminal to match.
This removes the "virtual cursor" that has been in use by the terminal
emulator since the beginning. The original rationale for using the
virtual cursor was to avoid having to support additional UI methods to
change the cursor color for other (non-TUI) UIs, instead relying on the
TermCursor and TermCursorNC highlight groups.
The TermCursor highlight group is now used in the default 'guicursor'
value, which has a new entry for Terminal mode. However, the
TermCursorNC highlight group is no longer supported: since terminal
windows now use the real cursor, when the window is not focused there is
no cursor displayed in the window at all, so there is nothing to
highlight. Users can still use the StatusLineTermNC highlight group to
differentiate non-focused terminal windows.
BREAKING CHANGE: The TermCursorNC highlight group is no longer supported.
