A hard-coded value of 50px is too large for text boxes with a size that
is less than 50px. Reduce this to 24px, and further limit it by the size
of the overflown box.
This change should move us forward toward emoji support, as we are no
longer limited by our own OpenType implementation, which was failing
to parse the TrueType Collection format used to store emoji fonts
(at least on macOS).
This is a preparation for upcoming changes where Gfx::Typeface will
depend on `FontDatabase::should_force_fontconfig()`, so we will no
longer be able to construct typefaces from FontDatabase constructor
because of circular dependency.
Currently we rely on parser returning an error if encoded data cannot be
parsed into a valid WOFF or WOFF2 font, which is not going to be true
after switching to Skia that sometimes does not fail even if a data does
not represent a valid font.
When an editable node is focused and one of the arrow/home/end keys are
pressed while shift is held, we will now create or update the document's
selection. There is a bit of nuance to the behavior here, which matches
how the cursor behaves in other engines.
We will of course want to abstract this in the future to extend any non-
editable node text selections. This also does not implement holding ctrl
to jump by word, rather than grapheme.
When performing a hit test of type TextCursor, it would check if the
position is around each fragment and not just inside it. This resulted
in always selecting the first fragment checked.
This commit computes the distance of each hit test result, and picks the
closest one.
When deciding if the grid containers min size should be limited by a
max size. Check for a max height or width depending on the dimension,
instead of just always checking for a max width.
If a key is pressed when the media player is in focus, which causes the
media player to perform some action, that key event is no longer
propagated further.
When we want to inject a CSS counter for a line, we need to be sure to
handle if we had previously opened a styled span for the current source
substring. For example, if we see a new line in the middle of a comment,
we will have previously opened the following tag:
<span class="comment">
So when injecting a new line and the <span class="line"> element (for
CSS counters), we need to close the previous span and insert a newly
opened tag to continue using the style.
If the Downloads directory exists, we will use it (note that this will
respect the XDG_DOWNLOAD_DIR environment variable).
Otherwise, we will ask the UI layer to retrieve a download directory
from the user. This directory is not saved, so it will be re-prompted
every time. Once a proper settings UI is complete, we will of course
integrate with that for persistent settings.
In some cases, we have a timestamp as a double in milliseconds. We then
would convert it to nanoseconds as a BigInt, just to bring it back to a
double for TZDB lookups. Add an overload to avoid this needless round
trip.
Even though the underlying time zone is already cached by LibUnicode, JS
performs additional expensive lookups with that time zone. There's no
need to do those lookups again until the system time zone has changed.
Note that we can currently only use simdutf for Base64 decoding if the
provided stopBeforePartial option is loose, which is the default. There
is an open issue for simdutf to implement strict and stop-before-partial
options. Until then, for those options, we implement a slow decoder that
is written exactly as the spec steps dictate.
See: https://github.com/simdutf/simdutf/issues/440
Choosing options from the `<select>` will load and display that style
sheet's source text, with some checks to make sure that the text that
just loaded is the one we currently want.
The UI is a little goofy when scrolling, as it uses `position: sticky`
which we don't implement yet. But that's just more motivation to
implement it! :^)
This will be used by the inspector, for showing style sheet contents.
Identifying a specific style sheet is a bit tricky. Depending on where
it came from, a style sheet may have a URL, it might be associated with
a DOM element, both, or neither. This varied information is wrapped in
a new StyleSheetIdentifier struct.
This is to enable the inspector to show this source.
There's a fairly hefty FIXME here because duplicating the source text is
a significant waste of memory. But I don't want to get too sidetracked.
This is only used for CSS style sheets. One case wants it as a String,
and the others don't care, but will in future also want to have the
source as a String.
