This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.
There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.
This patch moves the following things to being GC-allocated:
- Bindings::CallbackType
- HTML::EventHandler
- DOM::IDLEventListener
- DOM::DOMEventListener
- DOM::NodeFilter
Note that we only use PlatformObject for things that might be exposed
to web content. Anything that is only used internally inherits directly
from JS::Cell instead, making them a bit more lightweight.
This will be inherited by "legacy platform objects", i.e objects that
need to hijack indexed and/or named property access as described in the
IDL spec: https://webidl.spec.whatwg.org/#dfn-legacy-platform-object
Instead of overriding JS::Object virtuals, subclasses only need to
implement a very simple interface for property queries.
Note that this code is taken verbatim from code generator output.
I didn't write any of this now, so it's effectively "moved" code.
The UCD only cares about a few locales for special casing rules (az, lt,
and tr). Unfortunately, LibUnicode cannot use LibLocale once the
libraries are separate because LibLocale will need to use LibUnicode for
many more things; thus there would be a circular dependency. Instead,
just generate the small enum needed for this one use case.
This is generated by GenerateLocaleData, which will soon be in the
Locale namespace. Move it out of CurrencyCode.h, as that will continue
to live in the Unicode namespace.
Currently, LibUnicodeData contains the generated UCD and CLDR data. Move
the UCD data to the main LibUnicode library, and rename LibUnicodeData
to LibLocaleData. This is another prepatory change to migrate to
LibLocale.
To prepare for placing all CLDR generated data in a new library,
LibLocale, this moves the code generators for the CLDR data to the
LibLocale subfolder.
The generated locale data contains an enum also named Variant, as
variants are part of locale strings. This hasn't been an issue, but as
includes are reordered, the order in which the enum and AK::Variant are
included may cause an ambiguity error.
This patch adds the ability to select multiple entries in a column using
a rubber band selection. Currently the implementation is lacking support
for expanding a selection using the ctrl modifier.
This patch extracts logic for getting colum at an event position and for
getting an index in a column at an event position from
index_at_event_position into separate functions.
