This patch makes both of these classes inherit from RefCounted and
Bindings::Wrappable, plus some minimal rejigging to allow us to keep
using them internally while also exposing them to web content.
This adds support for the [Unscopable] extended attribute to attributes
and functions.
I believe it should be applicable to all interface members, but I
haven't done that here.
This currently only supports pair iterables (i.e. iterable<key, value>)
support for value iterables (i.e. iterable<value>) is left as TODO().
Since currently our cmake setup calls the WrapperGenerator separately
and unconditionally for each (hard-coded) output file iterable wrappers
have to be explicitly marked so in the CMakeLists.txt declaration, we
could likely improve this in the future by querying WrapperGenerator
for the outputs based on the IDL.
This patch essentially just splits the non return-specific logic from
generate_return_statement (i.e. the wrapping of the cpp value into
a javascript one) into a separate function generate_wrap_statement that
can be used to wrap any cpp value during wrapper generation.
This custom attribute will be used for objects that hold onto arbitrary
JS::Value's. This is needed as JS::Handle can only be constructed for
objects that implement JS::Cell, which JS::Value doesn't.
This works by overriding the `visit_edges` function in the wrapper.
This overridden function calls the base `visit_edges` and then forwards
it to the underlying implementation.
This will be used for CustomEvent, which must hold onto an arbitrary
JS::Value for it's entire lifespan.
A legacy platform object is a non-global platform object that
implements a special operation. A special operation is a getter, setter
and/or deleter. This is particularly used for old collection types,
such as HTMLCollection, NodeList, etc.
This will be used to make these spec-compliant and remove their custom
wrappers. Additionally, it will be used to implement collections that
we don't have yet, such as DOMStringMap.
This does a few things, that are hard to separate. For a while now, it's
been confuzing what `StyleValue::is_foo()` actually means. It sometimes
was used to check the type, and sometimes to see if it could return a
certain value type. The new naming scheme is:
- `is_length()` - is it a LengthStyleValue?
- `as_length()` - casts it to LengthStyleValue
- `has_length()` - can it return a Length?
- `to_length()` - gets the internal value out (eg, Length)
This also means, no more `static_cast<LengthStyleValue const&>(*this)`
stuff when dealing with StyleValues. :^)
Hopefully this will be a bit clearer going forward. There are lots of
places using the original methods, so I'll be going through them to
hopefully catch any issues.
These now crash as VM::call() uses ThrowExceptionOr<T>, which refuses to
hold an empty JS::Value as its non-exception result.
We only need to return an empty value when should_return_empty() says
so for the return value of throw_dom_exception_if_needed().

For `number` and `integer` types, you can add a range afterwards to add
a range check, using similar syntax to that used in the CSS specs. For
example:
```json
"font-weight": {
...
"valid-types": [
"number [1,1000]"
],
...
}
```
This limits any numbers to the range `1 <= n <= 1000`.
Previously, we have not been validating the values for CSS declarations
inside the Parser. This causes issues, since we should be discarding
invalid style declarations, so that previous ones are used instead. For
example, in this code:
```css
.foo {
width: 2em;
width: orange;
}
```
... the `width: orange` declaration overwrites the `width: 2em` one,
even though it is invalid. According to the spec, `width: orange` should
be rejected at parse time, and discarded, leaving `width: 2em` as the
resulting value.
Many properties (mostly shorthands) are parsed specially, and so they
are already rejected if they are invalid. But for simple properties, we
currently accept any value. With `property_accepts_value()`, we can
check if the value is valid in `parse_css_value()`, and reject it if it
is not.
We already expand shorthands in the cascade, so there's no need to
preserve them in the output.
This patch reorganizes the CSS::PropertyID enum values so that we can
easily iterate over all shorthand or longhand properties.
This patch adds a basic initial implementation of these API's.
Since LibWeb currently doesn't support workers, this implementation of
messaging doesn't bother with serializing and deserializing messages.
When parsing shorthand values, we'd like to use
`property_initial_value()` to get their longhand property values,
instead of hard-coding them as we currently do. That involves
recursively calling that function while the `initial_values` map is
being initialized, which causes problems because the shorthands appear
alphabetically before their longhand components, so the longhands aren't
initialized yet!
The solution here is to perform 2 passes when generating the code,
outputting properties without "longhands" first, and the rest after.
This could potentially cause issues when shorthands have multiple
levels, in particular `border` -> `border-color` -> `border-left-color`.
But, we do not currently define a default value for `border`, and
`border-color` takes only a single value, so it's fine for now. :^)
We'll use this to prevent repeating common tool dependencies. They all
depend on LibCore and AK only. We also want to encapsulate common
install rules for them.
This namespace will be used for all interfaces defined in the URL
specification, like URL and URLSearchParams.
This has the unfortunate side-effect of requiring us to use the fully
qualified AK::URL name whenever we want to refer to the AK class, so
this commit also fixes all such references.
This lets you query if a given Quirk applies to a given PropertyID.
Currently this applies only to the "Hashless hex color" and "Unitless
length" quirks.
This removes the awkward String::replace API which was the only String
API which mutated the String and replaces it with a new immutable
version that returns a new String with the replacements applied. This
also fixes a couple of UAFs that were caused by the use of this API.
As an optimization an equivalent StringView::replace API was also added
to remove an unnecessary String allocations in the format of:
`String { view }.replace(...);`
