Having two ways that `<position>` is represented is awkward and
unnecessary. So, let's combine the two paths together. This first step
copies and modifies the `parse_position()` code to produce a
`PositionStyleValue`.
Apart from returning a StyleValue, this also makes use of automatic enum
parsing instead of manually comparing identifier strings.
Display a warning when some images are missing, instead of crashing.
Also, don't keep old images around when loading a new set, and make use
of get_piece_graphic() more often.
Previously we would give up on loading the piece images if one fails.
That was awkward because 2 out of 3 places where `set_piece_set_name()`
is called can't propagate errors, so we'd just crash.
Instead, let's skip any images that fail to load, and then when painting
the preview, skip any missing bitmaps and show a warning message that
some are missing.
This will be required for propagating the current animation time to all
relevant timelines, which each propagate that time to all of their
relevant animations.
This does _NOT_ correspond to anything in the IDL or ECMAScript spec,
but is a custom extended attribute.
We use it to define the "enumerated" values of an attribute
Instead of a StringView. This allows us to preserve the nice O(1) string
compare property of FlyString, and not needing to allocate when one is
needed.
Ideally all other places in Token should have similar changes done, but
to prevent a huge amount of churn, just change ident for now.

Notable changes that affect us include:
* The Islamic Calendar is now localized as the Hijri Calender (in en-US)
but has not been updated for all locales. So this patch updates tests
where possible and removes a few test cases that currently cannot be
localized.
* The und locale has received more likely subtag data (the und locale is
basically a pseudo-locale meaning "undetermined").
* The exponential symbol in the Arabic number system was changed from
U+0627 to U+0623.
It's a little awkward that one caller of this is passing through an
Optional<String> and another an Optional<DeprecatedString>, but that
should be fixed some point in the future with further DeprecatedString
porting.
No IDL file pulls in these requiring DeprecatedString support, so we
are now able to remove these functions! :^)
Also leave a FIXME while we are at it, as ideally this function would
take an Optional<FlyString> - but the IDL generator does not currently
support this.
These were DeprecatedFlyStrings, but had no reason to be. We were not
making use of the O(1) lookup, so instead of porting it over to a
FlyString, just make it a StringView.
This is the API for NamedNodeMap which we are wanting to eventually use
instead of taking a StringView. Currently we just end up deferring to
the StringView versions of these functions, but at some stage in the
future, this will allow us to have O(1) comparison when making attribute
lookups.
In the meantime, the advantage of this API is that it makes it much less
awkward to use than the StringView variant when you have an
Optional<FlyString> namespace to pass through.
The original value 15 was too little: it made our
`weighted_boolean_fair_false` test fail every now and then.
This is because a fair coin (P(false) = 0.5) will hit the same value 15
times in a row with a probability (1/2)^15: around once in a 32k tries.
With the bumped up value, this is now once in 1 billion tries. Should
lower the test flakiness enough (if our random number generator is
truly uniform), while 30 tries is still an OK amount of computation for
randomized tests to do, compared to 15.
Now that x86-specific Assembler will be compiled on every architecture
we can't rely on void* being the right width.
It also fixes compilation on targets which have void*
be different length from u64 (WASM in particular).
This is in preparation for making LibJIT support multiple architectures.
Assembler will now be typedefed to the specific assembler
for a particular architecture.
Additionally, there's now JIT_ARCH_SUPPORTED which is defined on
architectures which LibJIT supports.
This makes JS::JIT::Compiler less architecture-specific
and unifies aligning the stack into a single operation,
where previously we were doing it separately for preserved registers
and for stack arguments.
* Compare array size to 3 and 4, not 4 and 5
* Fix literal typo in error message

Representing a text run panting command as a vector of glyphs, rather
than as a string simplifies collecting of unique glyphs which is a
prerequisite for `prepare_glyphs_texture()` call.
Text painting operates in two steps:
1. Preparation of a texture that contains all the glyphs required for
text painting, along with metadata that describes the locations of
those glyphs within texture beforehand.
2. Blitting glyphs from the prepared texture onto corresponding glyph
quads.
Users of LibAccelGfx will need to call `prepare_glyphs_texture()`,
passing a set of all unique (font, code_paint) pairs, before painting
any text.
This change separates a part of the `draw_text_run()` function, which
is responsible for calculating the positions for glyphs that need to be
painted, into a separate function called `get_glyph_run()`.
It is a part of the preparation for text run painting using OpenGL,
where we can't immediately blit glyph bitmaps but instead need to
prepare a sequence of quads for them in advance.
Since 2023-09-08, Clang trunk has had a bug which causes a segfault when
evaluating certain `requires` expressions inside templated lambdas.
There isn't an imminent fix on the horizon, so let's work around the
issue by specifying the type of the offending lambda arguments
explicitly.
See https://github.com/llvm/llvm-project/issues/67260
Using ErrorType::ReferencePrimitiveSetProperty the errors for primitives
now look like "Cannot set property 'foo' of number '123'".
The strict-mode-errors test has been adjusted and re-enabled.
In case of {get func() {}, set func() {}} we were wrongly setting the
function name to 'func' and then later trying to replace an empty name
with 'get func'/'set func' which failed.
Instead, set the name to 'get func'/'set func' right away.
The code in put_by_property_key is kept, for when that is called
by put_by_value.
Previously these were DeprecatedStrings that contained a null state.
After the null state was removed, the nullability of these members was
broken. This doesn't seem to cause any problems currently as the HTML
parser is not inserting attributes with their full qualified name, but
after we fix that problem, this bug surfaces.
The first thing that `set_selection` does is return early if the DOM-
loaded flag is false. Set it to true so it can actually do something.
This fixes inspecting a DOM node from the context menu.
We currently have StylePropertiesModel and AriaPropertiesStateModel in
LibWebView. These depend on GUI::Model and GUI::ModelIndex, which is the
only reason that the non-Serenity Ladybird chromes require LibGUI.
Further, these classes are very nearly idenitical.
This creates a PropertyTableModel to provide the base functionality for
all table-based model types used by all Ladybird chromes. It contains
code common to the style / ARIA table models, and handles the slight
differences between the two (namely, just the manner in which the values
are flattened into a list during construction).
The Qt and Serenity chromes can create thin wrappers around this class
to adapt its interface to their chrome-specific model classes (i.e.
QAbstractItemModel and GUI::Model).
We currently have DOMTreeModel and AccessibilityTreeModel in LibWebView.
These depend on GUI::Model and GUI::ModelIndex, which is the only reason
that the non-Serenity Ladybird chromes require LibGUI. Further, these
classes are very nearly idenitical.
This creates a TreeModel class to provide the base functionality for all
tree-based model types used by all Ladybird chromes. It contains code
common to the DOM / accessibility tree models, and handles the slight
differences between the two (namely, just the formatting of each node's
text for display).
The Qt and Serenity chromes can create thin wrappers around this class
to adapt its interface to their chrome-specific model classes (i.e.
