Previously we would disable console debug messages on all non Serenity
platforms as it caused double printing on lagom `js`. This patch limits
this to the `js` utility, allowing LibWeb to print debug messages
regardless of the operating system :^)
Previously, Playground would always preview the rendered GML in a frame
next to the editor. This can be annoying when trying to work with small
or large widget hierarchies since the size of the preview is tied to the
size of the editor. Now there is a view menu which allows you to toggle
between the frame or a separate window which can be resized independent
of the editor.
When converting to UTC, the UTC AO first tries to disambiguate possible
time zone offsets for the given local time. When doing so, the
GetNamedTimeZoneEpochNanoseconds AO must *subtract* the found time zone
offset from the local time to convert to UTC. The same is performed
later in the UTC AO when returning the final UTC time (step 5).
This is an editorial change in the Temporal spec. See:
https://github.com/tc39/proposal-temporal/commit/1b051cc
Note that since Date's implementation of this AO uses Crypto bigints
rather than allocating JS bigints, this change has the fallout of
removing some unused VM parameters and adding an overload of the
IsValidEpochNanoseconds AO for use without a JS::BigInt.
This is a normative change in the ECMA-262 spec. See:
https://github.com/tc39/ecma262/commit/43fd5f2
For the most part, these AOs are hoisted from Temporal.
Note that despite being a normative change, the expectation is that
this change does not result in any behavior differences.
Add classes ExplicitTrackSizing and MetaGridTrackSize which will allow
for managing properties like auto-fill and minmax.
In the following CSS example there are 3 classes that will be used:
grid-template-column: repeat(auto-fill, minmax(50px, 1fr) 75px);
ExplicitTrackSizing - will contain the entire value. e.g.
repeat(auto-fill, minmax(50px, 1fr) 75px)
With a flag if it's a repeat, as well as references to the
MetaGridTrackSizes which is the next step down.
MetaGridTrackSize:
Contain the individual grid track sizes. Here there are two:
minmax(50px, 1fr) as well as 75px.
This way can keep track if it's a minmax function or not, and the
references to both GridTrackSizes in the case it is, or in just the one
if it is not.
GridTrackSize:
Is the most basic element, in this case there are three in total; two of
which are held by the first MetaGridTrackSize, and the third is held by
the second MetaGridTrackSize.
Examples: 50px, 1fr and 75px.
Replace the manual creation of symlinks with the
`--enable-compat-symlinks` configure option, which automatically creates
the symlinks that we want and more.
As it turns out, we sometimes query the intrinsic height of a box before
having fully resolved and/or constrained its containing block. Because
of this, we may enter intrinsic sizing with different amounts of
available width for the same box.
To accommodate this scenario, we now allow caching of multiple intrinsic
heights, separated by the amount of available width provided as input.
This colors a bit outside the lines of the specification, but the spec
doesn't offer a proper explanation for how descendants of a flex item
are supposed to have access to the flex item's main size for purposes
of percentage resolution.
The approach I came up with here was to take the hypothetical main size
of each flex item, and assign it as a temporary main size. This allows
percentage resolution in descendants to work against the pre-flexing
main size of items. This seems to match how other engines behave,
although it feels somewhat dirty. If/when we learn more about this,
we can come up with something nicer.
