On macOS, it's a bit trickier to not install them, as we're using the
MACOSX_PACKAGE_LOCATION file property to get them into the build
directory and install tree in the same way.
This has been implemented in Qt for quite some time. This patch adds the
same feature to AppKit. This is needed to run many WPT subtests with the
AppKit chrome. This is also needed to handle window.open, target=_blank
link clicks, etc.
This is overriding the URL passed to e.g. window.open and link clicks on
an <a target=_blank> element.
Note: This alone is not enough to support such use cases. We will also
need to actually implement opening child web views. But getting this fix
out of the way first makes that patch a bit simpler.
It's getting a bit unwieldy to maintain as an inlined string. Move it to
its own file so it can be edited with syntax highlighting and other IDE
features.
The main motivator here was noticing that --disable-sql-database did not
work with AppKit. Rather than re-implementing this there, move ownership
of these classes to WebView::Application, so that each UI does not need
to individually worry about it.
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.
AppKit uses Private Use Area code points for a large collection of
functional keys (arrows, home/end, etc.). Re-assign them to 0 to avoid
tripping up WebContent's key handler.
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! :^)
On Android there's really no real way to provide command line flags.
We are using a dummy Main::Argument that only contains "ladybird"
as a name of the program.
The strings of Main::Argument cannot be empty, otherwise the program
throws an error. However the argc and argv can be set to 0 and nullptr
For some reason, IOSurface results in a completely blank render on Intel
machines. It's not clear why, so do not use IOSurface for now in order
to allow Intel users to run the browser.
Before this change, we were passing CGColorSpaceCreateDeviceRGB() to
CGImageCreate(), causing the system to assume that the image data is
in a device-specific RGB space without any color profile adjustments.
If your monitor is more vibrant than the assumed profile (for example,
a wide-gamut display), colors may appear over-saturated as there's no
correction applied for how the display actually renders those colors.
We now pass CGColorSpaceCreateWithName(kCGColorSpaceSRGB) instead,
which makes colors look the same in Ladybird as in other browsers. :^)
This allows us to get identical metrics on macOS and Linux. Without
this, Skia will use CoreText on macOS and give us slightly different
text metrics. That causes layout tests to be slightly different on
different platforms, which is a huge headache. So let's not do that.
You can now launch Ladybird and headless-browser with --force-fontconfig
to load fonts through fontconfig. Tests run in this mode by default.
The AppKit Application class is responsible for launching all helper
processes. This had to be moved to a .cpp file because we were unable to
include headers with the Protocol namespace in .mm files, as they would
conflict with the Protocol interface defined by Apple.
Now that this namespace has been renamed to Requests, we can remove this
workaround.
When working on the Inspector's HTML, it's often kind of tricky to debug
when an element is styled / positioned incorrectly. We don't have a way
to inspect the Inspector itself.
This adds a button to the Inspector to export its HTML/CSS/JS contents
to the downloads directory. This allows for more easily testing changes,
especially by opening the exported HTML in another browser's dev tools.
We will ultimately likely remove this button (or make it hidden) by the
time we are production-ready. But it's quite useful for now.
This forwards all drag-and-drop events from the UI to the WebContent
process. If the page accepts the events, the UI does not handle them.
Otherwise, we will open the dropped files as file:// URLs.

The identifier "Protocol" is claimed by Objective-C and Swift for use
by the language's built-in protocol conformance feature, which is
similar to Rust traits or Java interfaces.
Rename LibProtocol -> LibRequests, and its namespace from Protocol to
Requests to accomodate this.
We use instances of `Gfx::Bitmap` to move pixel data all the way from
raw image bytes up to the Skia renderer. A vital piece of information
for correct blending of bitmaps is the alpha type, i.e. are we dealing
with premultiplied or unpremultiplied color values?
Premultiplied means that the RGB colors have been multiplied with the
associated alpha value, i.e. RGB(255, 255, 255) with an alpha of 2% is
stored as RGBA(5, 5, 5, 2%).
Unpremultiplied means that the original RGB colors are stored,
regardless of the alpha value. I.e. RGB(255, 255, 255) with an alpha of
2% is stored as RGBA(255, 255, 255, 2%).
It is important to know how the color data is stored in a
`Gfx::Bitmap`, because correct blending depends on knowing the alpha
type: premultiplied blending uses `S + (1 - A) * D`, while
unpremultiplied blending uses `A * S + (1 - A) * D`.
This adds the alpha type information to `Gfx::Bitmap` across the board.
It isn't used anywhere yet.
This removes the --enable-callgrind-profiling flag, and replaces it with
a --profile-process=<process-name> flag. For example:
ladybird --profile-process=WebContent
ladybird --profile-process=RequestServer
This allows profiling any helper process with callgrind.
This removes the --debug-web-content flag, and replaces it with a
--debug-process=<process-name> flag. For example:
ladybird --debug-process=WebContent
ladybird --debug-process=RequestServer
This allows attaching gdb to any helper process.
Currently, if we want to add a new e.g. WebContent command line option,
we have to add it to all of Qt, AppKit, and headless-browser. (Or worse,
we only add it to one of these, and we have feature disparity).
To prevent this, this moves command line flags to WebView::Application.
The flags are assigned to ChromeOptions and WebContentOptions structs.
Each chrome can still add its platform-specific options; for example,
the Qt chrome has a flag to enable Qt networking.
There should be no behavior change here, other than that AppKit will now
support command line flags that were previously only supported by Qt.
The TabBar itself does not stretch the entire width of the TabWidget,
because it leaves space for the width of the new-tab button. So, we
manually tell Qt to paint the TabBar's background into the gap.
Fixes#768.
Makes use of the fact that QTabWidget automatically reserves space
for "corner widgets", and gives us the ability to override their
location with a custom style.
Also, determine the height of the new-tab button using the height of the
tab bar, instead of a hard-coded 32px which was too tall on MacOS.
The default limit (at least on Linux) causes us to run out of file
descriptors at around 15 tabs. Increase this limit to 8k. This is a
rather arbitrary number, but matches the limit set by Chrome.
Skia painter is visibly faster than LibGfx painter and has more complete
CSS transforms support. With this change:
- On Linux, it will try to use Vulkan-backend with fallback to
CPU-backend
- On macOS it will try to use Metal-backend with fallback to
CPU-backend
- headless-browser always runs with CPU-backend in layout mode
If no header includes the prototype of a function, then it cannot be
used from outside the translation unit it was defined in. In that case,
it should be marked as `static`, in order to avoid possible ODR
problems, unnecessary exported symbols, and allow the compiler to better
optimize those.
If this warning triggers in a function defined in a header, `inline`
needs to be added, otherwise if the header is included in more than one
TU, it will fail to link with a duplicate definition error.
The reason this diff got so big is that Lagom-only code wasn't built
with this flag even in Serenity times.
Enforce the use of the CPU backend in test mode to ensure that ref-tests
produce consistent results across different computers, as this
consistency cannot be achieved with the GPU backend.
This resolves a bug where if you opened a link in a new tab and quickly
went back to the original, the navigation buttons would update for the
new page shortly after.
