We're calling this in a way that is incorrect, and so the algorithm's
assumption that the next token is an `<ident-token>` is wrong, and we
have to handle that failing. Ideally we would just stop calling this
incorrectly, but until then, let's actually document what is happening.
The code had to change a bit to match. Previously, we appended an empty
sub-list immediately, but now we append it at the end. The difference
is that if there are no tokens, we now correctly return an empty
list-of-lists, instead of a list containing an empty list.
We now correctly call convert_to_rule() outside of this function.
As before, I've renamed `parse_as_rule()` -> `parse_as_css_rule()` to
match the free function that calls it.
This is not actually used by anything currently, but it should be used
for `@media` and other at-rules.
Removed the public parse_as_list_of_rules() because public functions
should be things that outside classes actually need to use.
`parse_a_stylesheet()` should not do any conversion on its rules. This
change corrects that. There are other places where we get this wrong,
but one thing at a time. :^)
This is an editorial change in the Intl spec. See:
https://github.com/tc39/ecma402/commit/087995chttps://github.com/tc39/ecma402/commit/233d29c
This also adds a missing spec link for the sanctioned units and fixes a
broken spec link for IsSanctionedSingleUnitIdentifier. In LibUnicode,
the NumberFormat generator is updated to use the constexpr helper to
retrieve sanctioned units.
CSS Values and Units Module Level 5 defines attr as:
`attr(<q-name> <attr-type>?, <declaration-value>?)`
This implementation does not contain support for the type argument,
effectively supporting `attr(<q-name>, <declaration-value>?)`
We now position inline-level boxes based on ascent and descent metrics
from the font in use. This makes our basic text layouts look a lot more
like those produced by other browsers. :^)
I've tried to match the terminology used by the CSS Inline Layout spec.
This will regress Acid2 a little bit, and probably various other sites,
but on the whole it's the direction we should be heading, so let's go.
This avoids a bunch of unnecessary work in Painter which not only took
time, but sometimes also led to alignment issues. draw_text_run() will
draw the text where we tell it, and that's it.
This API does:
- Take a Utf8View
- Take the starting point on the baseline as its input coordinate
This API does not:
- Align the text
- Wrap the text
- Elide too-long text into "..."
Show "domain" and "path" as the first two columns. Since we're showing
all cookies for all domains and all paths, you will probably want to
see the domain and path before the actual cookie name and value.
This commit upstreams most of the C++ bits of the LibJS test262 runner
at https://github.com/linusg/libjs-test262/, specifically everything but
the main.cpp file serving as the actual executable.
Since all of these are just regular JS objects, I opted to put them in
LibJS itself, in a new Contrib/ directory like many other projects have
one. Other code that can end up there in the future is the runtime for
esvu, which might even share some functionality with test262's $262
object.
The code has been copied verbatim, and only a small number of changes
have been made:
- Putting everything into the JS::Test262 namespace
- Removing now redundant JS namespace prefixes
- Updating includes to use absolute <LibJS/...> paths
- Updating the SPDX-License-Identifier comments from MIT to BSD-2-Clause
I gained permission to change the license and upstream these changes
from all the major contributors to this code: Ali, Andrew, David, Idan.
The removal of the code from the source repository is here:
https://github.com/linusg/libjs-test262/pull/54
This is only the first step, the goal is to eventually upstream the
actual libjs-test262-runner executable and supporting Python scripts
into SerenityOS as well.
Unlike BFC root blocks with height:auto, when the block *isn't* a BFC
root, we don't have to look for the "bottommost" block-level child and
determine the width from that.
Instead, we should just look at the last in-flow block-level child.
This was already indicated in the spec comment next to the code, but
the code itself was wrong.
This makes the body element on Acid3 have the correct height. It also
introduces a small regression on Acid2 that we'll have to track down.
Preserve floating point precision and delay rounding until the last
moment when figuring out where to paint background layers. This fixes an
issue on Acid3 where a thin sliver of red was visible because the
background X position was incorrectly rounded by 1px.
The find widget appears on Ctrl+F.
It uses the GUI::TextEditor search API to search for text, which also
takes care of highlighting the search results.
This adds a search API to TextEditor.
The API that is similar to "find_text" of TextDocument (which is used
internally to do the search).
All search results (as well as the current one) are highlighted with
a "span collection", which is pretty neat :^)
TextDocument::set_spans() now also takes a "span collection index"
argument.
TextDocument keeps a map between a span collection index and its spans.
It merges the spans from all collections into a single set of spans
whenever set_spans() is called.
This allows us to style a document with multiple layers of spans, where
as previously we only supported a single layer of spans that was set
from the SyntaxHighlighter.
When parsing the "style" attribute on elements, we'd previously ask the
CSS parser for a PropertyOwningCSSStyleDeclaration. Then we'd create a
new ElementCSSInlineStyleDeclaration and transfer the properties from
the first object to the second object.
This patch teaches the parser to make ElementCSSInlineStyleDeclaration
objects directly.
By using enclosing_int_rect(), borders and backgrounds of boxes were
sometimes 1 pixel off, making things slightly larger than they should
be. Fix this by using to_rounded() instead of enclosing_int_rect().
There's definitely more of these type of issues lurking in the code,
and we'll get to them in time.
This feature needs a bit more work, so let's disable it by default.
Note that the shell will still use _complete_foo if it is defined
regardless of this setting.
POSIX describes WCHAR_MIN and WCHAR_MAX in stdint.h(0P), while
wchar.h(0P) only says "as described in stdint.h".
As there isn't a trivial path of "may make visible", just move it to a
shared header and include it from both files.
This fixes 2 bugs in our current implementation:
* Properties deleted during iteration were still being iterated
* Properties with the same name in both the object and it's prototype
were iterated twice
Previously, we only allowed floats to take up its own border box's worth
of horizontal space when laid out inside an IFC.
We should instead consume the full margin box horizonally. This fixes an
issue where a floated box on Acid3 had {width:20px; margin-right:-20px;}
but still consumed 20px of the previously available space, despite being
moved out of the way by its own negative margin.
When doing max-content layout, we were not committing newlines even
though we were supposed to due to white-space:pre*.
This broke the WPT harness due to a VERIFY() in ChunkIterator where we
were assuming the commit would always succeed.
Thanks to Orphis for reporting this! :^)
When the spec tells us to measure from the top content edge of a block,
that just means we should measure from Y=0. We don't need to go looking
for a child box with a negative top offset and measure from there.
