`visitCalculationExpression` is now properly implemented.
This also adds concrete test classes that extend `RecursiveAstVisitor`
and `RecursiveStatementVisitor` to ensure similar issues are avoided in
the future whenever new AST nodes are added.
This check was previously checking whether *any* variables were left
in this configuration, which could include variables that were adopted
from outer configurations. This threw invalid errors when that outer
configuration would have been satisfied by another variable (or
forward) later in the file.

`@at-root` should now work properly in a nested import as long as the
only `@use` or `@forward` rules present are for built-in modules.
This is a partial but not complete fix for #1347. It's a bit hacky to
special case built-in modules here, but since they represent the only
real legitimate case for using this combination of features, it lets us
fix the bug for this case and avoid the bordering-on-infeasible work of
fixing this for user-defined modules.
These getters are only available through the sass_api package. This
will allow the Sass embedded compiler to more explicitly send the
color information it has on hand.
Fixes#1401 and #1414.
Adds `Dependency`, `SassDeclaration`, and `SassReference` interfaces,
which expose some getters that multiple AST nodes have in common with a
single type.
These also add getters for common subspans (URL, name, and namespace) to
the interfaces.
We weren't properly merging multiple @extend rules that were added to
an upstream module at the same time, so some of them weren't being
marked as satisfied.
Closes#1393
When an error occurred in a stylesheet loaded by a custom importer
with a custom URL scheme, the Node error wrapper tried to convert that
URL into a path and ended up crashing.
Closes#1138
When a path was returned at the same time as a file's contents, it was
interpreted as a URL without first being translated to one. This
crashed for absolute Windows paths.
Closes#1410
Rather than constructing this explicitly to match Node Sass's API, we
construct it with canonical URLs and convert it into the format
expected by the Node Sass API (a mix of paths and URLs) in the
compatibility layer.
We weren't properly awaiting a call to CssStylesheet.accept(), which
meant that it could try to continue doing work asynchronously in the
wrong context.
Closes#1318
To support this, we now run Node-Sass-style relative loads outside of
the Node importer. This allows the evaluator to check whether a
relative load succeeded and use that to determine whether the
stylesheet counts as a dependency.
