Problem: When a folded line has virtual lines attached, the following
problems occur:
- The virtual lines are drawn empty.
- The 'foldtext' line is drawn empty.
- The cursor is drawn incorrectly.
Solution: Check whether virtual lines belong to a folded line.

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Enable and fix bugprone-misplaced-widening-cast warning.
Fix some modernize-macro-to-enum and readability-else-after-return
warnings, but don't enable them. While the warnings can be useful, they
are in general too noisy to enable.
Before only win_line lines were considered. this applies nodelta
to all screen elements. Causes some failures, which might indeed
indicate excessive redraws.
- Added 'spell' option to extmarks:
Extmarks with this set will have the region spellchecked.
- Added 'noplainbuffer' option to 'spelloptions':
This is used to tell Neovim not to spellcheck the buffer. The old
behaviour was to spell check the whole buffer unless :syntax was set.
- Added spelling support to the treesitter highlighter:
@spell captures in highlights.scm are used to define regions which
should be spell checked.
- Added support for navigating spell errors for extmarks:
Works for both ephemeral and static extmarks
- Added '_on_spell_nav' callback for decoration providers:
Since ephemeral callbacks are only drawn for the visible screen,
providers must implement this callback to instruct Neovim which
regions in the buffer need can be spell checked.
The callback takes a start position and an end position.
Note: this callback is subject to change hence the _ prefix.
- Added spell captures for built-in support languages

Problem: The screen.c file is much too big.
Solution: Split it in three parts. (Yegappan Lakshmanan, closesvim/vim#4943)

This is an approximation vim-patch 8.1.2057. Applying the patch directly
isn't feasible since our version of screen.c has diverged too much,
however we still introduce drawscreen.c and drawline.c:
- screen.c is now a much smaller file used for low level screen functions
- drawline.c contains everything needed for win_line()
- drawscreen.c contains everything needed for update_screen()

Add space around arithmetic operators '+' and '-'.
Remove space between back-to-back parentheses, i.e. ')(' vs. ') ('.
Remove space between '((' or '))' of control statements.
Add space between ')' and '{' of control statements.
Remove space between function name and '(' on function declaration.
Collapse empty blocks between '{' and '}'.
Remove newline at the end of the file.
Remove newline between 'enum' and '{'.
Remove newline between '}' and ')' in a function invocation.
Remove newline between '}' and 'while' of 'do' statement.
Problem: Syntax coloring and highlighting is in one big file.
Solution: Move the highlighting to a separate file. (Yegappan Lakshmanan,

Don't add sign extmarks to state->active. Instead when drawing signs,
perform a full line scan for sign marks. This allows decor_redraw_line
to be moved back inside the `!number_only` block in screen.c, which
prevents decor scans when redrawing the number column when
'relativenumber' is set.
Fixes: #17638
Previously b_signcols was invalidated whenever a sign was added/removed
or when a buffer line was added/removed.
This change introduces a sentinel linenr_T into the buffer state which
is a line number used to determine the signcolumn. With this
information, we can invalidate the signcolumn less often. Now the
signcolumn is only invalidated when a sign or line at the sentinel line
number is removed.
Add the following options to extmarks:
- sign_text
- sign_hl_group
- number_hl_group
- line_hl_group
- cursorline_hl_group
Note: ranges are unsupported and decorations are only applied to
start_row
marktree.c was originally constructed as a "generic" datatype,
to make the prototyping of its internal logic as simple as possible
and also as the usecases for various kinds of extmarks/decorations was not yet decided.
As a consequence of this, various extra indirections and allocations was
needed to use marktree to implement extmarks (ns/id pairs) and
decorations of different kinds (some which is just a single highlight
id, other an allocated list of virtual text/lines)
This change removes a lot of indirection, by making Marktree specialized
for the usecase. In particular, the namespace id and mark id is stored
directly, instead of the 64-bit global id particular to the Marktree
struct. This removes the two maps needed to convert between global and
per-ns ids.
Also, "small" decorations are stored inline, i.e. those who
doesn't refer to external heap memory anyway. That is highlights (with
priority+flags) are stored inline, while virtual text, which anyway
occurs a lot of heap allocations, do not. (previously a hack was used
to elide heap allocations for highlights with standard prio+flags)
TODO(bfredl): the functionaltest-lua CI version of gcc is having
severe issues with uint16_t bitfields, so splitting up compound
assignments and redundant casts are needed. Clean this up once we switch
to a working compiler version.
This allows to more quickly skip though regions which has non-decorative
marks when redrawing. This might seem like a gratuitous
micro-optimization in isolation.
But!
Soon decorations are gonna crop into other hot inner-loop paths,
including the plines.c code for calculating the horizontal and
vertical space of text. Then we want to quickly skip over regions with
"only" overlaying decorations (which do not affect text size)
* refactor: format with uncrustify
* fixup(dundar): fix functions comments
* fixup(dundar): remove space between variable and ++/--
* fixup(dundar): better workaround for macro attributes
This is done to be able to better use uncrustify rules for macros
* fixup(justin): make preprocessors follow neovim style guide
Since the providers are ordered by ns_id, inserting a new provider may
require shifting existing providers around to maintain this ordering.
When this happens, we need to allocate a new element at the end of the
vector and then shift the larger elements to the right. Rather than
iterating (incorrectly) with a loop and copying each item, use memmove
to copy the entire block.
