New APIs

• SameTypeRequirementSyntax has a new RightType nested type.

  • Description: The Swift parser can now parse values as types in certain situations, so the new type reflects the possibility of the argument being either an ExprSyntax or a TypeSyntax.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2859

• SameTypeRequirementSyntax has a new LeftType nested type.

  • Description: The Swift parser can now parse values as types in certain situations, so the new type reflects the possibility of the argument being either an ExprSyntax or a TypeSyntax.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2859

• GenericArgumentSynax has a new Argument nested type.

  • Description: The Swift parser can now parse values as types in certain situations, so the new type reflects the possibility of the argument being either an ExprSyntax or a TypeSyntax.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2859

• GenericParameterSyntax now has a new specifier property.

  • Description: With the introduction of value generics, generic parameters can now be optionally preceded by either a let or an each. The specifier property captures the token representing which one was parsed.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2785

• IntegerLiteralExprSyntax and FloatLiteralExprSyntax now have a computed representedLiteralValue property.

  • Description: Allows retrieving the represented literal value when valid.
  • Issue: https://github.com/apple/swift-syntax/issues/405
  • Pull Request: https://github.com/apple/swift-syntax/pull/2605

• SyntaxProtocol now has a method ancestorOrSelf.

  • Description: Returns the node or the first ancestor that satisfies condition.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2696

• Error protocol now has an asDiagnostics(at:) method.

  • Description: This method translates an error into one or more diagnostics, recognizing DiagnosticsError and DiagnosticMessage instances or providing its own Diagnostic as needed.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/1816

• Added a new library SwiftIfConfig.

  • Description: This new library provides facilities for evaluating #if conditions and determining which regions of a syntax tree are active according to a given build configuration.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/1816

• SwiftBasicFormat adds a method indented(by:) to all syntax node types.

  • Description: This method indents a node’s contents using a provided piece of Trivia, optionally including the first line.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2843

• Parser.ExperimentalFeatures has a new init?(name: String) initializer.

  • Description: This initializer returns the Parser.ExperimentalFeatures value that matches the experimental parser feature with the given name. The name must be spelled the same way as it is when passed to the compiler using the -enable-experimental-feature flag.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2895

API Behavior Changes

• SyntaxProtocol.trimmed detaches the node
  • Description: Getting a trimmed version of a node detaches it from its parent. Having the trimmed node be attached to a parent was not intuitive because eg. printing the parent node would have the trimmed trivia missing, most likely forming invalid Swift code.
  • Pull Request: https://github.com/apple/swift-syntax/pull/2689

Deprecations

• GenericParameterSyntax deprecated eachKeyword in favor of specifier

  • Description: specifier is now used to grab either the each keyword for a generic parameter or the let keyword.
  • Pull request: https://github.com/swiftlang/swift-syntax/pull/2785

• IncrementalEdit deprecated in favor of SourceEdit

  • Description: IncrementalEdit is being dropped for SourceEdit. SourceEdit has deprecated compatibility layers to make it API-compatible with IncrementalEdit
  • Issue: https://github.com/apple/swift-syntax/issues/2532
  • Pull request: https://github.com/apple/swift-syntax/pull/2604

• ClosureCaptureSyntax.init(leadingTrivia:specifier:name:equal:expression:trailingComma:trailingTrivia:) deprecated in favor of a new ClosureCaptureSyntax.init(leadingTrivia:_:specifier:_:name:_:initializer:_:trailingComma:_:trailingTrivia:) initializer.

  • Description: ClosureCaptureSyntax now has an initializer property instead of equal and expression. Additionally, the name property is no longer optional.
  • Pull request: https://github.com/swiftlang/swift-syntax/pull/2763

• Indenter in SwiftSyntaxBuilder has been deprecated in favor of the new indented(by:) in SwiftBasicFormat.

  • Description: Indenting is really more of a formatting operation than a syntax-building operation. Additionally, the indented(by:) method is more intuitive to use than a SyntaxRewriter. Aside from BasicFormat, there are no other public SyntaxRewriter classes in the package.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2843

API-Incompatible Changes

• SameTypeRequirementSyntax.rightType has changed types from TypeSyntax to SameTypeRequirementSyntax.RightType

  • Description: The Swift parser can now parse values as types in certain situations, so the new type reflects the possibility of the argument being either an ExprSyntax or a TypeSyntax.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2859

• SameTypeRequirementSyntax.leftType has changed types from TypeSyntax to SameTypeRequirementSyntax.LeftType

  • Description: The Swift parser can now parse values as types in certain situations, so the new type reflects the possibility of the argument being either an ExprSyntax or a TypeSyntax.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2859

• GenericArgumentSyntax.argument has changed types from TypeSyntax to GenericArgumentSyntax.Argument

  • Description: The Swift parser can now parse values as types in certain situations, so the new type reflects the possibility of the argument being either an ExprSyntax or a TypeSyntax.
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2859

• Moved Radix and IntegerLiteralExprSyntax.radix from SwiftRefactor to SwiftSyntax.

  • Description: Allows retrieving the radix value from the literal.text.
  • Issue: https://github.com/apple/swift-syntax/issues/405
  • Pull Request: https://github.com/apple/swift-syntax/pull/2605

• FixIt.Change gained a new case replaceChild(data:).

  • Description: The new case covers the replacement of a child node with another node.
  • Issue: https://github.com/swiftlang/swift-syntax/issues/2205
  • Pull Request: https://github.com/swiftlang/swift-syntax/pull/2758
  • Migration steps: In exhaustive switches over FixIt.Change, cover the new case.

• ClosureCaptureSyntax.name is no longer optional.

  • Description: Due to the new ClosureCaptureSyntax node structure, name property is non-optional.
  • Pull request: https://github.com/swiftlang/swift-syntax/pull/2763
