DeprecatedFlyString relies heavily on DeprecatedString's StringImpl, so
let's rename it to A) match the name of DeprecatedString, B) write a new
FlyString class that is tied to String.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Prevent media query parser from falling back into
MediaQuery::create_not_all() for queries with unknown media type.
With this change following test works correctly:
http://wpt.live/css/css-conditional/at-media-001.html
This parses conic-gradient()s while also attempting to share the bulk
of the parsing code with linear-gradient()s. This is done by extracting
the <color-stop-list> parsing to a "fill in the blacks" generic
function. This is a little awkward but cuts down on a lot of copy
pasting of code.
This parses <position> according to the following grammer:
<position> = [
[ left | center | right ] || [ top | center | bottom ]
|
[ left | center | right | <length-percentage> ]
[ top | center | bottom | <length-percentage> ]?
|
[ [ left | right ] <length-percentage> ] &&
[ [ top | bottom ] <length-percentage> ]
]
The code is a little hairy and simply tries each alternative in turn,
manually checking the possible orders. There may be a better way to
represent this.
Refactor various classes in the GridTrackSize file for the incoming
named_tracks feature.
Previously the ExplicitTrackSizing had mixed responsiblities with the
newly-named GridRepeat class. This made it so it was not possible to
have multiple repeats within a single 'GridTrackSizeList' definition.
The MetaGridTrackSize class had both the responsibilities of being a
container for minmax values as well as for simple GridSizes. By uniting
the different possible values (repeat, minmax, default) into the
ExplicitGridTrack class are able to be more expressive as to the
different grid size modalities.
The GridTrackSizeList will be useful as compared to a
Vector<ExplicitGridTrack> since this way can keep track of the declared
line names. These same line names are able to be declared within the
values of a repeat function, hence the presence of a GridTrackSizeList
inside the GridRepeat class.
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.
Add ability to use values passed to grid-template-columns and
grid-template-rows for CSS Grid layout within a repeat() function.
E.g. grid-template-columns: repeat(2, 50px); means to have two columns
of 50px width each.
These changes improve the parsing of the span property, including
handling negative values for the span (defaults to 1), as well as when
no number is passed (also defaults to 1).
Implement span correctly when indicated in the grid-column-start,
grid-row-start, etc. CSS properties. Previously it had been implemented
as if span was something that went alongside the position property, but
actually it seems like if you do 'span 3' in the grid-column-start
property, for example, this means it literally spans 3 blocks, and the
3 has nothing to do with position.
