Note that js_rope_string() has been folded into this, the old name was
misleading - it would not always create a rope string, only if both
sides are not empty strings. Use a three-argument create() overload
instead.
Gfx::Color is always 4 bytes (it's just a wrapper over u32) it's less
work just to pass the color directly.
This also updates IPCCompiler to prevent from generating
Gfx::Color const &, which makes replacement easier.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This adds support for parsing the ::placeholder pseudo-element and
injecting an anonymous layout node with that element when the input
element's data is empty.
The ::placeholder pseudo element was added in commit 1fbad9c, but the
total number of pseudo elements was not updated. Instead of this manual
bookkeeping, add a dummy value at the end of the enumeration for the
count.
Prevent media query parser from falling back into
MediaQuery::create_not_all() for queries with unknown media type.
With this change following test works correctly:

C++20 can automatically synthesize `operator!=` from `operator==`, so
there is no point in writing such functions by hand if all they do is
call through to `operator==`.
This fixes a compile error with compilers that implement P2468 (Clang
16 currently). This paper restores the C++17 behavior that if both
`T::operator==(U)` and `T::operator!=(U)` exist, `U == T` won't be
rewritten in reverse to call `T::operator==(U)`. Removing `!=` operators
makes the rewriting possible again.

When mixing calc() and var(), we're forced to delay resolving them until
we're in StyleComputer. Previously we'd just skip over them.
This patch handles calc() in the same pass as attr(). We reparse the
calc() value after var() expansion, and then try to resolve it to a
constant value if possible. If it's not possible, we leave the calc()
where it is, and maybe layout can figure it out later.
Note that I've only implemented resolution to integer and percentage in
this commit. There are more things a calc() could resolve to, and we
should implement those as well.
These will be used when resolving calc() values in StyleComputer.
It's indeed strange that calc() resolves to tokens, but it's how the
engine currently handles those things. There is room for improvement.
This parses conic-gradient()s while also attempting to share the bulk
of the parsing code with linear-gradient()s. This is done by extracting
the <color-stop-list> parsing to a "fill in the blacks" generic
function. This is a little awkward but cuts down on a lot of copy
pasting of code.
This parses <position> according to the following grammer:
<position> = [
[ left | center | right ] || [ top | center | bottom ]
|
[ left | center | right | <length-percentage> ]
[ top | center | bottom | <length-percentage> ]?
|
[ [ left | right ] <length-percentage> ] &&
[ [ top | bottom ] <length-percentage> ]
]
The code is a little hairy and simply tries each alternative in turn,
manually checking the possible orders. There may be a better way to
represent this.
This class represents a <position> and handles resolving it to a
Gfx::FloatPoint relative to some rectangle.
It can handle all forms of <position>:
- Two presets:
left center
- A preset + a length percentage:
10% bottom
- Or relative to some edges:
right 20% bottom 30px
This commit adds a simple style value (which is an abstract image)
to represent conic-gradient()s.
This commit also starts to factor out some reusable parts of the
linear-gradient() style value for other gradient types.
