Previously any children would be layout using a BlockFormattingContext.
Now we at least differentiate between IFC and BFC if the sizes in
question are not constrained by other things.
Calling `is_identifier()` here was wrong, since it just means you can
get an Identifier from it. This meant that an `auto` LengthStyleValue
would return true, then it would get `static_cast` to the wrong class,
and return a garbage value.
Basically, I really need to tidy up the API for StyleValue, so it's
clear whether `is_foo()` means the object is a `FooStyleValue`, or it
can just return a `foo` value.
For `number` and `integer` types, you can add a range afterwards to add
a range check, using similar syntax to that used in the CSS specs. For
example:
```json
"font-weight": {
...
"valid-types": [
"number [1,1000]"
],
...
}
```
This limits any numbers to the range `1 <= n <= 1000`.
This brings us a few nice benefits:
- We only generate a `StyleValueList` for properties that accept
multiple values.
- We reject declarations that have too many values.
- We check the type of each value that is parsed, to make sure it's
acceptable to the property.
Probably there are some regressions here, since this is
Later, we can also replace many of the `is_foo()` functions and lambas
inside the Parser with more calls to `property_accepts_value()`. Also we
can remove some checks when resolving styles, since only valid types of
values will get to that point. But one step at a time. :^)
Previously, we have not been validating the values for CSS declarations
inside the Parser. This causes issues, since we should be discarding
invalid style declarations, so that previous ones are used instead. For
example, in this code:
```css
.foo {
width: 2em;
width: orange;
}
```
... the `width: orange` declaration overwrites the `width: 2em` one,
even though it is invalid. According to the spec, `width: orange` should
be rejected at parse time, and discarded, leaving `width: 2em` as the
resulting value.
Many properties (mostly shorthands) are parsed specially, and so they
are already rejected if they are invalid. But for simple properties, we
currently accept any value. With `property_accepts_value()`, we can
check if the value is valid in `parse_css_value()`, and reject it if it
is not.
We don't want a property like `background` to fall back to parsing as a
single value or StyleValueList if `parse_background_style_value()`
fails. We just want it to fail.
We need to exclude this file from analysis for now, as there is a bug in
the sonar-runner tool where it crashes when trying to understand the use
of AK::Variant in LibWasm/Parser/Parser.cpp
See #10122 for details + link to the bug report to Sonar Cloud.
I was experimenting with using caching while doing the initial prototype
of the Sonar Cloud workflow. However the cache size for the static
analysis data ended up being large enough that it would put us over the
git hub actions limit. Given that we currently only run this pipeline
once a day, it seems reasonable to just remove caching.
If in the future we decide to run the pipeline on every PR, caching
would become crucial as the current un-cached analysis time is around
1 hour and 50 minutes. If we did this we would need to move the pipeline
to Azure DevOps where we have effectively infinite cache available.
Prior this commit we were always dereferencing the image bitmap pointer,
even if it was null, which resulted in a crash when trying to open
the context menu when an image wasn't loaded.
Closes: #10178
Negative margins are a headache anyways, and allowing them to be
negative lead to weird behavior.
This patch avoids vasty wrong height-calculations by limiting the
allowed margins to positive numbers when evaluating the height of a
block.
Large enough content ranges produced unclamped scrubbers sized zero,
effectively clamped by their integer type. This led to zero sized
page_increments and scrubbers which didn't budge on gutter events.
This fixes broken gutters in FontEditor and TextEditor for large
files.
This is a helpful option to prevent unwanted side effects, distinguish
between user and programmatic input, etc. Sliders and SpinBoxes were
implementing it idiosyncratically, so let's generalize the API and
give Buttons and TextEditors the same ability.
This also moves getElementsByTagName to ParentNode to remove the code
duplication between Document and Element. This additionally fixes a bug
where getElementsByTagName did not check if the element was a
descendant, meaning it would also include the context element if the
condition matched.
In StyleResolver, we were rejecting single values for properties that
take 1-4: `border-color`, `border-style`, and `border-width`. Now, we
handle them correctly. I also added support for `calc()` and `var()` to
`padding` and `margin`.
This fixes the orange border on Acid2, which now correctly appears
black. :^)
