This will simplify upcoming Label porting in ThemeEditor.
|
|
|
|
This can be used to convert a profile-dependent color to the L*a*b*
color space.
(I'd like to use this to implement the DeltaE (CIE 2000) algorithm,
which is a metric for how similar two colors are perceived.
(And I'd like to use that to evaluate color conversion roundtrip
quality, once I've implemented full conversions.)
|
|
|
|
This means we now actually respect @media (prefers-color-scheme: dark)
by default when in dark mode. :^)
|
|
This makes it easier to see what the result will be when using two
solid colors.
|
|
Previously, clicking outside the bounds of the board when the window
was resized, could cause a crash.
|
|
The asynchronous DNS requests library c-ares was ported to serenity
|
|
To be able to port c-ares the IN6_IS_ADDR_V4COMPAT and
various macros of the form IN6_IS_ADDR_MC_XX_LOCAL were added
as well as the IN_CLASS{A,B} macros

Since multiboot_modules_count is set to 0, we can safely set the
multiboot_modules pointer to 0 (null pointer), as we don't use multiboot
on aarch64 anyway.

Length units are either relative to the font, or to the viewport, but
never both. So we can save some work by not gathering font metrics for
a viewport unit, and not retrieving the viewport for a font unit.
Currently this is only helpful when the `to_px(Layout::Node)` method is
called, but since that is 208 places according to CLion, (plus 33
indirect uses via `Length::resolved()`) it still seems worthwhile. :^)
|
|
`*vi` and `*vb` vary on which direction they check depending on whether
the writing mode is horizontal or vertical, so they will need some
modification once we support that.
|
|
`sfoo` `lfoo` and `dfoo` are, for our purposes, identical to `foo`,
because we don't have dynamic GUI elements that cover the page content.
|
|
Using the rough heuristic instead of the actual spec measurement. It's
allowed by the spec, but not ideal:
> In the cases where it is impossible or impractical to determine the
ideographic advance measure, it must be assumed to be 1em.
|
|
As noted, the ascent of the font is not the best heuristic for this, but
it is one that's listed as OK to use by the spec:
> In the cases where it is impossible or impractical to determine the
cap-height, the fontโs ascent must be used.
|
|
These are the same as `ex` and `ch`, but using the root element's
metrics. We now have this information available, so let's use it. :^)
|
|
This saves us from doing a lot of the same work multiple times, when we
want both the root font size and its line height.
|
|
Rather than passing an increasingly-unwieldy number of font parameters
individually to every function that resolves lengths, let's wrap them
up.
This is frustratingly close to being `Gfx::FontPixelMetrics`, but bitmap
fonts cause issues: We choose the closest font to what the CSS
requests, but that might have a wildly different size than what the
page expects, so we have to fudge the numbers.
No behaviour changes.

I missed this when removing calc() from Length. Oops!
|
|
They previously weren't sorted at all. Alphabetical would be nice, but
then things like `em` and `rem` would be separated. So, let's copy the
spec's order. That way it's easier to keep track of which units we have
or haven't implemented. (Since there are so many...)

Fix table box width calculation to minus horizonal borders from space
available for columns.

If you launch the Spreadsheet app by clicking on a CSV
(or other supported formats) the import dialog is immediately
launched. If you cancel out of the import the application ends
up in an empty state where there are no sheets added. When you
launch the app normally it defaults to having a blank sheet, so
we should have the same behaviour in this scenario to prevent users
from having to manually add the new/blank sheet before being able to
use the app
|
|
Cells can be updated with new background/foreground colors and then this
action can be undone/redone.
|
|
Enables the ability to undo changes in metadata without undoing chages
in data. Previously there was only CellUndoData which cannot undo things
such as changes in cell background color.
|
|
Allows the creation of CellChanges where the change is in the type
metadata instead of in data.
|
|
This patch adds radial gradients to the gradients tool.

This reuses the existing `RPi::Mailbox` interface to read the command
line via a VideoCore-specific mailbox message. This will have to be
replaced if that interface starts being smarter, as this is needed very
early, and nothing guarantees that a smarter Mailbox interface wouldn't
need to allocate or log, which is a no-no during early boot.
As the response string can be arbitrarily long, it's the caller's job to
provide a long enough buffer for `Mailbox::query_kernel_command_line`.
This commit chose 512 bytes, as it provides a large enough headroom over
the 150-200 characters implicitly added by the VC firmware.
The portable way would be to parse the `/chosen/bootargs` property of
the device tree, but we currently lack the scaffolding for doing that.
Support for this in QEMU relies on a patch that has not yet been
accepted upstream, but is available via our `Toolchain/BuildQEMU.sh`
script. It should, however, work on bare metal.

This commit backports my upstream QEMU patch to implement this
functionality, which is currently waiting for review.
It was submitted here:
https://lists.nongnu.org/archive/html/qemu-arm/2023-04/msg00549

|
If the SDL libraries are present on the system, QEMU will attempt to use
that for rendering the UI. This causes a crash when the AArch64 port
starts up with the following message:
> NSWindow drag regions should only be invalidated on the Main Thread!
Fix this by explicitly disabling SDL support.

The Raspberry Pi's mailbox interface does not guarantee that the
returned command line is null-terminated. This commit removes that
assumption from the current code, allowing the next commit to add
support for reading it on the Pi.
This also lets us eliminate a few manual `strlen()` calls :^)
|
|
This method returns a sub-span whose data pointer and size is aligned to
a specified alignment.
|
|
|
|
Given that XYZ and xyz are distinct things, let's use the correct
case for these member variables.
No behavior change.
|
|
|
|
|
|
Only implemented for matrix profiles so far.
This API won't be fast enough to color manage images, but let's
get something working before getting something fast.
|
|
...and make its return type unsigned.
|
|
Should be good enough.

A dialog is now displayed when an engine move results in a checkmate
or a draw. In the case of threefold repetition or the fifty move rule,
the engine will always accept a draw. A human player is asked if they
would like to accept a draw.

This commit implements following missing steps in table layout:
- Calculate final table height
- Resolve percentage height of cells and rows using final table height
- Distribute avilable height to table rows
|
|
If total max columns width (grid_max) is zero then available width
should be divided equally between columns. Previously there was
division by zero: `column.max_width / grid_max`.

This device was removed in b596af363c30de5323641fab69ad50c712f526e2, so
we can't really create anything related to it, therefore this piece of
code should be removed too.
|

Some hardware/software configurations crash KVM as soon as we try to
start Serenity. The exact cause is currently unknown, so just fully
revert it for now.
This reverts commit 897c4e5145474d55b247a4a3b5e6bf5420279e2f.
