Unlike syntax conceal, change highlight of concealed char
Can be used in tree-sitter using "conceal" metadata.

Problem: Syntax coloring and highlighting is in one big file.
Solution: Move the highlighting to a separate file. (Yegappan Lakshmanan,
closes vim/vim#4674)
https://github.com/vim/vim/commit/f9cc9f209ede9f15959e4c2351e970477c139614
Name the new file highlight_group.c instead.

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)

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.

position of extmark
|
| | |
|
| |
|
|
|
| |
Base priority is 0x1000, in order to stay kinda backward compatible.
Also set tree-sitter default highlight to 100 (middle-ish value)
|
| | |
|
| | |
|
|
|
Decorations will only grow more complex. move the to a separate
file, so that extmark.c remains about extmarks.
