Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *

LibHTML: Add HTMLHeadingElement for <h1> through <h6>

#pragma once
LibWeb: Move ARIA-related code into the Web::ARIA namespace ARIA has its own spec and is not part of the DOM spec, which is what the Web::DOM namespace is for (https://www.w3.org/TR/wai-aria-1.2/). This allows us to stay closer to the spec with function names and don't have to add the word "ARIA" to identifiers constantly - the namespace now provides that clarity.

LibWeb: Move HTML object model stuff into LibWeb/HTML/ Take a hint from SVG and more all the HTML classes into HTML instead of mixing them with the DOM classes.

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated 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.

WEB_PLATFORM_OBJECT(HTMLHeadingElement, HTMLElement);
LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

virtual ~HTMLHeadingElement() override;
LibWeb: Add a whole bunch of HTML DOM bindings Note that these aren't full implementations of the bindings. This mostly implements the low hanging fruit (namely, basic reflections) There are some attributes that should be USVString instead of DOMString. However, USVString is a slightly different definition of DOMString, so it should suffice for now.
2020-07-27 05:04:26 +01:00
LibWeb: Support more presentational hints from the HTML spec Specifically, this adds support for the align attribute when applied to heading, paragraph and caption elements.

virtual Optional<ARIA::Role> default_role() const override { return ARIA::Role::heading; }
LibWeb: Replace ARIA role static FlyStrings with an enum This replaces the FlyStrings for ARIA roles that were constructed in a [[gnu::constructor]] with a single enum. I came across this as the DOM inspector was crashing due to a null FlyString for an ARIA role. After fixing that, I was confused as to why these roles were not an enum. Looking at the spec there's a fixed list of roles and switching from references to static strings to an enum was pretty much an exercise in find and replace :). No functional changes (outside of fixing the mentioned crash).

LibWeb: Port Element interface from DeprecatedString This is the last IDL interface which was using DeprecatedString! :^)

// TODO: aria-level = the number in the element's tag name
LibWeb: Use FlyString where possible in NamedNodeMap We cannot port over Optional<FlyString> until the IDL generator supports passing that through as an argument (as opposed to an Optional<String>). Change to FlyString where possible, and resolve any fallout as a result.

LibWeb: Move setting of Web object prototypes to initialize() This needs to happen before prototype/constructor intitialization can be made lazy. Otherwise, GC could run during the C++ constructor and try to collect the object currently being created.
