Problem: Unsetting global variables earlier in #28578 to avoid
recursiveness, caused superfluous or even unlimited
showmode().
Solution: Partly revert #28578 so that the globals are unset at the end
of showmode(), and avoid recursiveness for ext UI by adding a
recursive function guard to each generated UI call that may
call a Lua callback.
Problem: Numberwidth may depend on number of signs with text in the
buffer and is not handled correctly for extmark signs.
Solution: Move legacy sign code for changed numberwidth so that it is
handled properly for legacy and extmark signs alike.
Problem: there is missing default title highlight when highlight not defined in title text chunk.
Solution: when attr is not set use default title highlight group.
Experimental and subject to future changes.
Add a way to redraw certain elements that are not redrawn while Nvim is waiting
for input, or currently have no API to do so. This API covers all that can be
done with the :redraw* commands, in addition to the following new features:
- Immediately move the cursor to a (non-current) window.
- Target a specific window or buffer to mark for redraw.
- Mark a buffer range for redraw (replaces nvim__buf_redraw_range()).
- Redraw the 'statuscolumn'.
Problem: Calling :redraw from vim.ui_attach() callback results in
recursive cmdline/message events.
Solution: Avoid recursiveness where possible and replace global "call_buf"
with separate, temporary buffers for each event so that when a Lua
callback for one event fires another event, that does not result
in invalid memory access.
Problem: Calculating line height for unnecessary amount of lines with
half-page scrolling (zhscn, after 9.1.0280)
Solution: Replace "limit_winheight" argument with higher resolution
"max" argument to which to limit the calculated line height

Instead of randomly disappearing because some random event might have
caused mid_start or bot_scroll_start to randomly take a low value, treat
intro message as a _first class stateful_ thing.
This means that intro message will kept being _redrawn_ as long as we
are in the state it should be shown. This also includes screen resizes.
you will not lose the intro message because there was a delay in
detecting terminal features.
A lot of functions in move.c only worked for curwin, alternatively
took a `wp` arg but still only work if that happens to be curwin.
Refactor those that are needed for update_topline(wp) to work
for any window.

Problem: infinite loop in win_update with 'smoothscroll' set when
window width is equal to textoff, or signed integer overflow
if smaller.
Solution: don't revalidate wp->w_skipcol in that case, as no buffer text
is being shown. (Sean Dewar)

Test_window_split_no_room changes were already cherry-picked earlier.
Problem: the amount of available space (v:echospace) on the command
line is not correct when showcmdloc is drawn into the
statusline or tabline.
Solution: only add SHOWCMD_COLS to the shown command column when
'showcmdloc' is set to last (Sam-programs)

vim-patch:9.1.0100: Redrawing can be improved with undo and 'spell'
Problem: When undoing with 'spell', redrawWinline() is called after
changed_lines(), while later win_update() sets redraw type to
UPD_NOT_VALID, even though w_redraw_top and w_redraw_bot are
still valid.
Solution: Only set redraw type to UPD_NOT_VALID when inserting/deleting
lines after parts of window has pending redraw, i.e., when
changed_lines() is called after redrawWinline().

Problem: Mechanism to prevent recursive screen updating is incomplete.
Solution: Add "redraw_not_allowed" and set it in build_stl_str_hl().

When "q" is set in 'shortmess' it now fully hides the "recording @a" message
when you are recording a macro instead of just shortening to "recording". This
removes duplication when using reg_recording() in the statusline.

Problem: Redrawing can be improved when inserting/deleting lines with 'number'.
Solution: Only redraw the number column of lines below changed lines.
Add a test as this wasn't previously tested.

Problem: The call to redraw_for_cursorline() in nv_mousescroll() is
unnecessary because redraw_for_cursorline() only sets redraw
type to UPD_VALID, and all code paths in do_mousescroll()
already set redraw type to at least UPD_VALID.
Solution: Remove call to redraw_for_cursorline() in nv_mousescroll().

Problem: Marks moved by undo may be lost to "b_signcols.count".
Solution: Count signs for each undo object separately instead of
once for the entire undo.
This expands on the global "don't pay for what you don't use" rules for
these special extmark decorations:
- inline virtual text, which needs to be processed in plines.c when we
calculate the size of text on screen
- virtual lines, which are needed when calculating "filler" lines
- signs, with text and/or highlights, both of which needs to be
processed for the entire line already at the beginning of a line.
This adds a count to each node of the marktree, for how many special
marks of each kind can be found in the subtree for this node. This makes
it possible to quickly skip over these extra checks, when working in
regions of the buffer not containing these kind of marks, instead of
before where this could just be skipped if the entire _buffer_
didn't contain such marks.
'foldtext' can be set to an empty string to disable and render the
line with:
- extmark highlight
- syntax highlighting
- search highlighting
- no line wrapping
- spelling
- conceal
- inline virtual text
- respects `fillchars:fold`
Currently normal virtual text is not displayed

Problem: Wrong "clear" argument passed to buf_signcols_count_range
when initializing "b_signcols.count" for the first time.
Solution: Pass kFalse so that the "nested" counter is not incorrectly
decremented.
Problem: The 'statuscolumn' is not redrawn on the wrapped part of a
line when moving the cursor with 'relativenumber' set.
Solution: Redraw the 'statuscolumn' for the entire line height in the
"col_rows" win_line() code path.
Problem: Some edge cases to the old (pre-#26406) and current "b_signcols"
structure result in an incorrectly sized "auto" 'signcolumn'.
Solution: * Implement a simpler 'signcolumn' validation strategy by immediately
counting the number of signs in a range upon sign insertion and
deletion. Decrease in performance here but there is a clear path
forward to decreasing this performance hit by moving signs to a
dedicated marktree, or by adding meta-data to the existing
marktree which may be queried more efficiently?
* Also replace "max_count" and keep track of the number of lines with
a certain number of signs. This makes it so that it is no longer
necessary to scan the entire buffer when the maximum number of signs
decreases. This likely makes the commit a net increase in performance.
* To ensure correctness we also have re-initialize the count for an
edited region that spans multiple lines. Such an edit may move the
signs within it. Thus we count and decrement before splicing the
marktree and count and increment after.
Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
grid_put_linebuf() used grid_clear() internally to handle clearing the
left part of a rightleft line. By reimplementing that internally, we
can instead use grid_put_linebuf() as the implementation of
grid_clear(), which in the end is a net reduction of code as grid_fill()
is used for nothing else.
win_draw_end: Implement "draw_margin" on a per-row basis which closer reflects how
terminals work. Also use the magic mirror for 'rightleft'
A bit big, but practically it was a lot simpler to change over all
fillchars and all listchars at once, to not need to maintain two
parallel implementations.
This is mostly an internal refactor, but it also removes an arbitrary
limitation: that 'fillchars' and 'listchars' values can only be
single-codepoint characters. Now any character which fits into a single
screen cell can be used.
Problem: The entire marktree needs to be traversed each time a sign is
removed from the sentinel line.
Solution: Remove sentinel line and instead keep track of the number of
lines that hold up the 'signcolumn' in "max_count". Adjust this
number for added/removed signs, and set it to 0 when the
maximum number of signs on a line changes. Only when
"max_count" is decremented to 0 due to sign removal do we need
to check the entire buffer.
Also replace "invalid_top" and "invalid_bot" with a map of
invalid ranges, further reducing the number of lines to be
checked.
Also improve tree traversal when counting the number of signs.
Instead of looping over the to be checked range and counting
the overlap for each row, keep track of the overlap in an
array and add this to the count.
Problem: Wrong scrolling in Insert mode with 'smoothscroll' at the
bottom of the window.
Solution: Don't use set_topline() when 'smoothscroll' is set.

This reverts commit fe30d8ccef.
The original commit intends to prevent heap-use-after-free with EXITFREE
caused by changedtick_di, which is no longer a problem.
Freeing buffers after freeing variables will cause heap-use-after-free
with EXITFREE when a partial is used as prompt callback.
FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
