Context Extensions¶

Helper methods for CodeFixContext and syntax projections.

CodeFixContext Extensions¶

Helper methods for finding syntax nodes at a diagnostic location:

// Generic find
OptionalSyntax<TSyntax> result = await context.FindDeclaration<TypeDeclarationSyntax>();

// Type-specific helpers
OptionalSyntax<ClassDeclarationSyntax> classDecl = await context.FindClass();
OptionalSyntax<MethodDeclarationSyntax> methodDecl = await context.FindMethod();
OptionalSyntax<PropertyDeclarationSyntax> propDecl = await context.FindProperty();
// Also: FindStruct(), FindInterface(), FindRecord(), FindEnum(),
//       FindField(), FindConstructor(), FindEvent(), FindParameter()

ValidSyntax<T>¶

A wrapper guaranteeing a non-null syntax node:

protected override CodeAction? CreateFix(Document document, ValidSyntax<TypeDeclarationSyntax> syntax)
{
    // syntax.Node is guaranteed non-null
    string name = syntax.Node.Identifier.Text;

    // Access the underlying node
    TypeDeclarationSyntax node = syntax.Node;
}
