In one case we can replace it with MUST() and accept the crash (we also
VERIFY() that there wasn't an exception); in the other case we don't
need to return after a throw completion.
Currently, we load the generated Unicode symbols with dlopen at runtime.
This is unnecessary as of 565a880ce5.
Applications that want Unicode data now link directly against the shared
library holding that data. So the same functionality can be achieved
with weak symbols.
This requires an implementation of the "text preparation algorithm" as
specified here:
html.spec.whatwg.org/multipage/canvas.html#text-preparation-algorithm
However, we're missing a lot of things such as the
CanvasTextDrawingStyles interface, so most of the algorithm was not
implemented. Additionally, we also are not able to use a LineBox like
the algorithm suggests, because our layouting infra is not up to the
task yet. The prepare_text function does nothing other than figuring out
the width of the given text and return glyphs with offsets at the
moment.
This is a static helper function for asking the user what they want to
do about unsaved changes. It behaves as a standard Yes/No/Cancel box
with text and buttons tailored to the typical unsaved changes use case.
A bloom filter creates fringes around bright areas in the image
mimicking the behavior of real-world cameras.
It gets its own category "Artistic" in the Filter Gallery since its not
one filter per se but a combination of multiple.
The filter works as follows:
- Get only the light areas (above a threshold) of the image
- Blur that image
- Compose onto the original image
With this BitmapMixer one can draw one Bitmap onto another with
different modes.
For now the only supported mixing methods implemented are Add and
Lightest (which is very naive).
The FastBoxBlurFilter has been living in LibGfx for a while and now
it's accessible in PixelPaint. The parameters for the filter are exposed
via the new Filter Gallery.
1268b39ba introduced template specialization when reading/writing
to/from the bitmap that increased the speed of the filter.
To keep that while supporting more than one BitmapFormat, the
appropriate {get,set}_pixel<>() functions are detemined and stored in
Function<>s.
The wrong conception that done() would stop the program flow right there
lead to the lambda not properly aborting when no filter was selected.
The ExecAborted would be processed and then the nullptr that was
m_selected_filter would be happily dereferenced.
This patch fixes that.
Now, the filters can supply the Filter Gallery with a GUI::Widget such
that the user can interact with the filter. The Filter Gallery in turn
only calls apply() on the filter once it should be run.
This decouples the PixelPaint filters a lot from the ones supported by
LibGfx and paves the way to filters with settings.
For now there still are just the plain LibGfx filters so this change
feels like introducing a lot of boilerplate, but in the future there
will be a lot more to see.
As noted in the prototype comments, this implementation becomes less
accurate as the precision approaches the limit of 100. For example:
(3).toPrecision(100)
Should result in "3." followed by 99 "0"s. However, due to the loss of
accuracy in the floating point computations, we currently result in
"2.9999999...".
There's only two places where we're using the C99 feature of array
designated initalizers. This feature seemingly wasn't included with
C++20 designated initalizers for classes and structs. The only two
places we were using this feature are suitably old and isolated that
it makes sense to just suppress the warning at the usage sites while
discouraging future array designated intializers in new code.
Enable the warning project-wide. It catches when a non-virtual method
creates an overload set with a virtual method. This might cause
surprising overload resolution depending on how the method is invoked.
Before this patch, `which ""` or `type ""` would say that the empty
string is `/usr/local/bin/`.
Convert callers to consistently call is_empty() on the returned string
while we're at it, to support eventually removing the is_null() String
state in the future.
Certain C Libraries have (unfortunately) included strings.h as a
part of string.h, which violates the POSIX spec for that specific
header. Some applications rely on this being the case, so let's
include it in our string.h
This allows specifying which directory to extract to or create
from.
I would have used the *at variants of the functions, but some
weren't implemented yet.
This is another major milestone on our journey towards removing global
VM exception state :^)
Does pretty much exactly what it says on the tin: updating
ASTNode::execute() to return a Completion instead of a plain value. This
will *also* allow us to eventually remove the non-standard unwinding
mechanism and purely rely on the various completion types.
In the end this is a nicer API than having separate has_{value,target}()
and having to check those first, and then making another Optional from
the unwrapped value:
completion.has_value() ? completion.value() : Optional<Value> {}
// ^^^^^^^^^^^^^^^^^^
// Implicit creation of non-empty Optional<Value>
This way we need to unwrap the optional ourselves, but can easily pass
it to something else as well.
This is in anticipation of the AST using completions :^)
When selecting a cell in the spreadsheet that was added
automatically as per the InfinitelyScrollableTableView
implementation, the background color is now filled correctly.
Previously, when navigating horizontally in a spreadsheet, after
a certain point the cells would not have the same background fill
color as the user would have experienced in the previous column
ranges (A-Z).
Previously we would create a temporary progress window to show a
progressbar while the coredump is processed. Since we're only waiting
on backtraces and CPU register states, we can move the progressbar
into the main window and show everything else immediately while the
slow parts are generated in a BackgroundAction.
On account of row and column headers, when a user navigates to
a cell (for example in the spreadsheet application) that is
outside of the view, the cell is not properly aligned and so
is partially cut-off. This fix takes into account the row and
column headers when calculating the Rect to pass to the
scroll_into_view function.
ECMA-402 now supports short-offset, long-offset, short-generic, and
long-generic time zone name formatting. For example, in the en-US locale
the America/Eastern time zone would be formatted as:
short-offset: GMT-5
long-offset: GMT-05:00
short-generic: ET
long-generic: Eastern Time
We currently only support the UTC time zone, however. Therefore, this
very minimal implementation does not consider GMT offset or generic
display names. Instead, the CLDR defines specific strings for UTC.
Spider was only updating the new bounding box area after drawing cards
from the deck - leaving behind a sliver of the old deck.
This was a regression, as the game previously used the old bounding
box, introduced by GH-11153.
Previously, SoundPlayer would read and enqueue samples in the GUI loop
(through a Timer). Apart from general problems with doing audio on the
GUI thread, this is particularly bad as the audio would lag or drop out
when the GUI lags (e.g. window resizes and moves, changing the
visualizer). As Piano does, now SoundPlayer enqueues more audio once the
audio server signals that a buffer has finished playing. The GUI-
dependent decoding is still kept as a "backup" and to start the entire
cycle, but it's not solely depended on. A queue of buffer IDs is used to
keep track of playing buffers and how many there are. The buffer
overhead, i.e. how many buffers "too many" currently exist, is currently
set to its absolute minimum of 2.
Previously, FlacLoader would read the data for each frame into a
separate vector, which are then combined via extend() in the end. This
incurs an avoidable copy per frame. By having the next_frame() function
write into a given Span, there's only one vector allocated per call to
get_more_samples().
This increases performance by at least 100% realtime, as measured by
abench, from about 1200%-1300% to (usually) 1400% on complex test files.
