This creates WebView::ConsoleClient to handle functionality that will be
common to the JS consoles of all Ladybird chromes. This will let each
chrome focus on just the UI.
Note that this includes the `console.group` functionality that only the
Serenity chrome previously had. This was a FIXME in the Qt chrome, and
it is implemented such that all chromes will receive this functionality
for free.
This is not we're supposed to do according to https://tc39.es/ecma262/#sec-runtime-semantics-propertydefinitionevaluation
Furthermore, this was observable by ToPrimitive looking up toString and
valueOf and potentially calling them if they exist. The big ticket
issue however is that for objects without toString and valueOf, such as
null-proto objects, this would unexpectedly throw.
When text paintables shift around in the tree due to line wrapping,
we may end up in a situation where some text node does not generate
a paintable (due to being all whitespace, for example), even though
in the previous layout pass, it *did* generate a paintable.
To prevent holding on to old paintables in such cases, we now do a
pass in LayoutState::commit() where we explicitly detach all old
paintables from the layout tree.
This tokenizes a page's source to produce HTML with syntax highlighting.
The first implementation here is rather simple; we do not yet implement
code folding, line numbers, etc.
The goal is for this to be used as the View Source implementation for
all Ladybird chromes.
We currently track the [line, column] position of every HTMLToken, as
this is what is needed for LibGUI's syntax highlighting. Some non-LibGUI
purposes (e.g. highlighting HTML with HTML) require a byte offset. Track
both during tokenization.
This moves some stuff around to make LibGUI depend on LibSyntax instead
of the other way around, as not every application that wishes to do
syntax highlighting is necessarily a LibGUI (or even a GUI) application.
We need to start looking from the beginning of current row if adding
new implicit column track made enough space to accomodate spanning item
This fixes placement for spanning grid items when `grid-auto-flow` is
specified to `column`.
The `Loader` uses a `Vector<Sample>` to store any samples that the
actual audio decoder returned that the loader client did not request
yet. However, it did not take that buffer into account when those
clients asked for the number of samples loaded. The buffer is an
internal implementation detail, and should not be reflected on the
external API.
This allows LibWeb to keep better track of audio position without any
desync caused by the buffer. When using the Serenity `PlaybackStream`
implementation as the back end for an `HTMLAudioElement`, this allows
us to perfectly stop on the exact last sample of the audio file, so it
will not stop before the media element can see that it has finished
playback.
Note that `Loader::get_more_samples()` also calls `loaded_samples()` to
determine how many samples are remaining to load into the output
buffer. However, this change appears to be correct even there, given
that the samples copied from the internal sample buffer are included in
that count.
The previous update time of 10 ms was set completely arbitrarily, but
puts an unnecessary load on the CPU. This reduces the rate, and it can
be adjusted in future depending on what web pages expect.
This implementation is very naive compared to the PulseAudio one.
Instead of using a callback implemented by the audio server connection
to push audio to the buffer, we have to poll on a timer to check when
we need to push the audio buffers. Implementing cross-process condition
variables into the audio queue class could allow us to avoid polling,
which may prove beneficial to CPU usage.
Audio timestamps will be accurate to the number of samples available,
but will count in increments of about 100ms and run ahead of the actual
audio being pushed to the device by the server.
Buffer underruns are completely ignored for now as well, since the
`AudioServer` has no way to know how many samples are actually written
in a single audio buffer.
Since `gethostbyname()` can't fail because of memory-related issues, it
has no way of representing a memory-related failure. We therefor use
`NO_RECOVERY` to represent a memory-related failure as well
as its normal name server related failures.
When a substitution refers to a 2-digit capture group that doesn't exist
we need to check if the first digit refers to an existing capture group.
In other words, '$10' should be treated as capture group #1, followed by
the literal '0' if 1 is a valid capture group but 10 is not.
This makes the Dromaeo "dom-query" subtest run to completion.
While we're here, assert that we're not doing this conversion when the
NavigationHistoryBehavior is still "auto", as the
HistoryHandlingBehavior enum is supposed to represent a "resolved"
behavior.
Instead of having a nested enum within a struct, use the macro
AK_ENUM_BITWISE_OPERATORS to add all the convienent has_flag free
functions and such for ease of use.
If the table used width has to be adjusted because of a cell with
percentage width, add back the undistributable space due to border
spacing. This is consistent with the width distribution algorithm, which
sets aside the undistributable space and the behavior of other browsers.
This is a normative change in the array from async proposal, see:
49cfde2
It fixes a double construction when Array.fromAsync is given an array
like object.
