This project is a part of the Xcode-shipped toolchain on macOS, but
needs built from source on other platforms. However, using the Xcode
version of the framework leads to a bunch of rpath confusion when
trying to link it the expected way. I suspect that there will be a
more intuitive way to link this library from the toolchain when it
stabilizes. So we'll build it everywhere :)
Instead of using a global setting, let's set this per-target. This
prevents conflicts when importing third-party dependencies that do
not tolerate the mode being "default".
At the same time, simplify CMakeLists magic for libraries that want to
include Swift code in the library. The Lib-less name of the library is
now always the module name for the library with any Swift additions,
extensions, etc. All vfs overlays now live in a common location to make
finding them easier from CMake functions. A new pattern is needed for
the Lib-less modules to re-export their Cxx counterparts.
We don't actually generate any such events ourselves. But Google Lens
will create one with the DataTransfer attribute set to that of any drop
event we send it.
Instead of CSSColorValue holding a Gfx::Color, make it an abstract class
with subclasses for each different color function, to match the Typed-OM
spec. This means moving the color calculations from the parsing code to
the `to_color()` method on the style value.
This lets us have calc() inside a color function, instead of having to
fully resolve the color at parse time. The canvas fillStyle tests have
been updated to reflect this.
The other test change is Screenshot/css-color-functions.html: previously
we produced slightly different colors for an alpha of 0.5 and one of
50%, and this incorrect behavior was baked into the test. So now it's
more correct. :^)
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.
USVString attributes Now replace any surrogates with the replacement
character U+FFFD and resolve any relative URLs to an absolute URL. This
brings our implementation in line with the specification.
The Web Platform Tests runner requires that some hostnames point to
localhost when running the tests locally. We now append these hostnames
to `/etc/hosts` if they aren't already present.
For a long time, we've used two terms, inconsistently:
- "Identifier" is a spec term, but refers to a sequence of alphanumeric
characters, which may or may not be a keyword. (Keywords are a
subset of all identifiers.)
- "ValueID" is entirely non-spec, and is directly called a "keyword" in
the CSS specs.
So to avoid confusion as much as possible, let's align with the spec
terminology. I've attempted to change variable names as well, but
obviously we use Keywords in a lot of places in LibWeb and so I may
have missed some.
One exception is that I've not renamed "valid-identifiers" in
Properties.json... I'd like to combine that and the "valid-types" array
together eventually, so there's no benefit to doing an extra rename
now.
Commit 35392d4d28 moved the
target_*_directories() calls (or rather their include()) before the
target declaration, so they fail because of the undefined target.
We can fix the problem by using global *_directories() instead.
Implements the corresponding encoders, selects the appropriate one when
encoding URL search params. If an encoder for the given encoding could
not be found, fallback to utf-8.
USVString is defined in the IDL spec as:
> The USVString type corresponds to scalar value strings. Depending on
> the context, these can be treated as sequences of either 16-bit
> unsigned integer code units or scalar values.
This means we need to account for surrogate code points by using the
replacement character.
This fixes the last test in https://wpt.live/url/url-constructor.any.html
In theory the clang module map should not have absolute paths for the
headers. Other Swift projects seem to use the -ivfsoverlay feature of
clang to work around this, but it seems difficult to get to work.
And modernize the cmake_parse_arguments() call at the top.
Ideally, we would pull these flags from the target we're generating
for, but the current CMake setup makes that prohibitively infeasible.
This ensures that we can get all the proper warnings on/off to get the
same diagnostics and other options when loading C++ headers into the
Swift frontend.
Add a simple shell script to update the local clangd configuration
according to the type of build selected by the user. Include
documentation on where the script might be useful when building
under different configurations.
For the SVG <use> element, we want to support loading HTML documents
that have a SVG element inside of it pointed to by the URL fragment.
In this situation we would need to fetch and parse the entire document
in SharedImageRequest (so that we can still cache the SVGs). Rename
SharedImageRequest to SharedResourceRequest to make the class a little
more generic for future usecases.
