Dart API #

• Breaking change: The first argument to NumberExpression() is now a double rather than a num.

• Add an optional argumentName parameter to SassScriptException() to make it easier to throw exceptions associated with particular argument names.

• Most APIs that previously returned num now return double. All APIs continue to accept num, although in Dart 2.0.0 most of these APIs will be changed to accept only double.

• UnaryOperationExpressions with operator not now include a correct span, covering the expression itself instead of just the operator.

• No user-visible changes.

• No user-visible changes.

• No user-visible chances.

• Breaking change: Convert all visitor superclasses into mixins. This includes RecursiveAstVisitor, RecursiveSelectorVisitor, RecursiveStatementVisitor, and StatementSearchVisitor. This has several effects;

  • You must use with to mix in visitors rather than extends.

  • It's now possible to mix multiple visitors into the same class, which wasn't possible with extends.

  • Because mixins can't be composed, when mixing in RecursiveAstVisitor you must explicitly mix in RecursiveStatementVisitor as well.

• Breaking change: Replace the minSpecificity and maxSpecificity fields on ComplexSelector, CompoundSelector, and SimpleSelector with a single specificity field.

• No user-visible changes.

• Refactor the CssMediaQuery API to support new logical operators:

  • Rename the features field to conditions, to reflect the fact that it can contain more than just the <media-feature> production.

  • Add a conjunction field to track whether conditions are matched conjunctively or disjunctively.

  • Rename the default constructor to CssMediaQuery.type() to reflect the fact that it's no longer by far the most commonly used form of media query.

  • Add a required conjunction argument to CssMediaQuery.condition().

  • Delete the isCondition getter.

• Provide access to Sass's selector AST, including the following classes: Selector, ListSelector, ComplexSelector, ComplexSelectorComponent, Combinator, CompoundSelector, SimpleSelector, AttributeSelector, AttributeOperator, ClassSelector, IdSelector, ParentSelector, PlaceholderSelector, PseudoSelector, TypeSelector, UniversalSelector, and QualifiedName.

• Provide access to the SelectorVisitor and RecursiveSelectorVisitor classes.

• Provide access to the Value.assertSelector(), Value.assertComplexSelector(), Value.assertCompoundSelector(), and Value.assertSimpleSelector() methods.

• First stable release.

• No user-visible changes since 1.0.0-beta.48.

• Add the SassApiColor extension to the "Value" DartDoc category.

• Add SassColor.hasCalculatedRgb and .hasCalculatedHsl extension getters.

• UseRule, ForwardRule, and DynamicImport now share a common Dependency interface that exposes a url getter and a urlSpan getter.

• VariableDeclaration, MixinRule, FunctionRule, Argument, and ConfiguredVariable now share a common SassDeclaration interface that exposes a name getter (with underscores converted to hyphens) and a nameSpan getter.

• Function calls with interpolation have now been split into their own AST node: InterpolatedFunctionExpression. FunctionExpression.name is now always a string (with underscores converted to hyphens). FunctionExpression also now has an originalName getter, which leaves underscores as-is.

• VariableExpression, IncludeRule, and FunctionExpression now share a common SassReference interface that exposes a namespace getter and a name getter (with underscores converted to hyphens), as well as corresponding namespaceSpan and nameSpan getters.
