From the specification:
It is a Syntax Error if StringValue of IdentifierName is the same
String value as the StringValue of any ReservedWord except for yield
or await.
It is a Syntax Error if this phrase is contained in strict mode code
and the StringValue of IdentifierName is: "implements", "interface",
"let", "package", "private", "protected", "public", "static", or
"yield".
It was previously writing directly to the underlying buffer instead of
using these methods. This has a benefit of dealing with BigInt64 and
BigUint64 for us already.
This is to make use of the new Value conversion methods.
This also moves the clamped u8 tag to ArrayBuffer from TypedArray and
the conversion to these methods, as the spec does it here.
js only accepted a single script file to run before this. With this
patch, multiple scripts can be run in the same execution environment,
allowing the user to specify a "preamble script" to be executed before
the main script.
This commit expands on 5eef07d232 by
automatically trying to coerce Type::String PropertyNames into numbers
when a caller checks if the PropertyName is_number/is_string.
This has several benefits:
- We no longer have to duplicate the number coercion code to every
function that accepts a PropertyNumber. (Or more likely, forget to.)
- This keeps the lazy nature of only doing the coercion when and if
there is a semantic difference to the different PropertyName types,
which means this shouldnt cause any performance drop.
- Since this coercion changes the state of the PropertyName itself the
result is essentially cached and can speed up any repeat uses of the
same PropertyName instance.
This now matches the spec's OrdinaryObjectCreate() across the board:
instead of implicitly setting the created object's prototype to
%Object.prototype% and then in many cases setting it to a nullptr right
away, it now has an 'Object* prototype' parameter with _no default
value_. This makes the code easier to compare with the spec, very clear
in terms of what prototype is being used as well as avoiding unnecessary
shape transitions.
Also fixes a couple of cases were we weren't setting the correct
prototype.
There's no reason to assume that the object would not be empty (as in
having own properties), so let's follow our existing pattern of
Type::create(...) and simply call it 'create'.
Using String() like we did before depends on objects having either
toString, valueOf, or @@toPrimitive, which is not the case for objects
with no prototype.
Remove the confusingly-named inflate_for_shadow() function and inline
its logic into render_to_cache(). And remove the m_shadow_offset
member variable since it was only needed locally in one place.
Also improve some variable names to make it more understandable what
is going on.
This way we don't have to allocate this at runtime. I'm intentionally
not using static constexpr here because that would put the variable
into the .rodata segment and would therefore increase the binary by
4kB.
The old code also failed to free() the buffer in the destructor, however
that wasn't much of an issue because the Mixer object exists throughout
the program's entire lifetime.
Previously `open_page` was called multiple times when opening the
application, once for the actual page, but also in
`tree_view.on_selection_change`. At startup there is no valid selection
yet, which caused an empty page to be loaded. Prevent this by early
returning if the `path` is null.
When REGEX_DEBUG is enabled, LibRegex dumps a table of information
regarding the state of the regex bytecode execution. The Compare opcode
manipulates state.string_position directly, so the string_position value
cannot be used to display where the comparison started; therefore, this
patch introduces a new variable to keep track of where we were before
the comparison happened.
This patch adds a GUI::TabWidget to the main UI and allows having
multiple images open at the same time.
Some of the changes here are a bit hackish and mechanical and there's
still code around that needs more work to fit better in the new world.
One nice side-effect of this change is that ImageEditor now always
has one Image associated with it, and it never changes.
