Extract the StyleMetrics from the style and pass it to the layout
lowering pass for application.
The tests were adjusted to explicitly specify the padding/spacing to
override the ugly style default.
The all_documents member does not have to be externally provided, as
long as we keep the typeloader in scope instead. Since we'll later pass
it down to the layout lowering pass, that's fine.
This will allow the online editor to load imports from URL asynchroniously later
Since currently the compiler is only working on a single thread, and that we
never await on a future that could block, it is allowed to use the spin_on executor
Given the test case
import { SomeType } from "somewhere.60";
import { Blah } from "foo.60";
and foo.60 trying to use "SomeType":
export Blah := SomeType {}
then the lookup for "SomeType" in foo.60 should fail. Instead it leaked
through the populated type registry when processing the dependencies for
the outer file.
This is fixed by ensuring that the type registry for a file only has the
global type registry as parent. To ensure that the test reliably covers
this, the import dependencies are now processed in declaration order
(hence the switch to IndexMap that preserves insertion order).
We decided that their type mapping is not ready for public API yet. For
example for duration we'd like to replace the opaque i64 with another
opaque type that however has convenient conversions to
std::time::Duration or std::chrono::milliseconds. We can't use either
directly because we need ffi compatibility, in order to create an
instance in C++ and pass it to the Rust run-time.
So this hides such properties and instead produces a warning.
Instead of panicking in later phase.
Use the same function in the syntax_tests that the one we use in the different
compiler frontend so that the problems would also be shown in the tests
The Rectangle element has properties for a border outline. If those are
used, then the generated code should use BorderRectangle. But if they are
not used, then we can fall back to just generating a Rectangle.
This is the counter part of the export statement and right now it's
implemented as a dumb recursive file loader. This can be extended in
thefuture to support cycles between files (but not types), if
theresolution of types is done lazily.
Instead of doing the SyntaxNodeWithSourceFile construction as late as
possible (in Document::from_node), we can do it as early as possible.
That'll reduce the chances of missing out the source file and prepares
for dependency loading just based on a SNWS :)
This also makes the source_file optional in the SNWS, but that's
consistent with what the diagnostics expect.
When going from the plain rowan::SyntaxNode tree to the syntax_nodes::*
elements, attach the source file and keep track of it from that point
on. That'll pave the way for proper multi-file diagnostics generated
later on from the passes, where we store syntax_nodes::* types.
This allows specifying additional component locations. It works for
simple structs, but not yet for more complex types due to a bug yet to
be fixed :-)
