Scalable Metaprogramming in Scala 3

A metaprogrammer should be able to reason about the semantics of the generated code. Multi-stage programming introduced an elegant and powerful solution to this problem. It follows a semantically driven approach to code generation, where semantics are full ...

Virtual ADTs for Portable Metaprogramming

Martin Odersky, Nicolas Alexander Stucki

Scala 3 provides a metaprogramming interface that represents the abstract syntax tree definitions using algebraic data types. To allow the compiler to freely evolve without breaking the metaprogramming interface, we present virtual algebraic data types (or ...

Semantics-preserving inlining for metaprogramming

Martin Odersky, Sébastien Jean R Doeraene, Nicolas Alexander Stucki

Inlining is used in many different ways in programming languages: some languages use it as a compiler-directive solely for optimization, some use it as a metaprogramming feature, and others lay their design in-between. This paper presents inlining through ...

A Practical Unification of Multi-stage Programming and Macros

Martin Odersky, Nicolas Alexander Stucki

Program generation is indispensable. We propose a novel unification of two existing metaprogramming techniques: multi-stage programming and hygienic generative macros. The former supports runtime code generation and execution in a type-safe manner while th ...

Truly abstract interfaces for algebraic data types: the extractor typing problem

Martin Odersky, Nicolas Alexander Stucki, Paolo Giosuè Giarrusso

Pattern matching enables inspecting algebraic data types, but typically prevents hiding the implementation of the matched algebraic data type. In Scala, instead, extractors also allow pattern matching on non-algebraic data types and invoking methods on the ...

Semantics-Driven Interoperability between Scala.js and JavaScript

Tobias Schlatter, Sébastien Jean R Doeraene, Nicolas Alexander Stucki

Hundreds of programming languages compile to JavaScript. Yet, most of them fail, at one level or another, to provide satisfactory interoperability with JavaScript APIs. This is limiting, as interoperability is at least required to manipulate web pages thro ...

RRB Vector: A Practical General Purpose Immutable Sequence

Martin Odersky, Tiark Rompf, Nicolas Alexander Stucki, Vlad Ureche

State-of-the-art immutable collections have wildly differing performance characteristics across their operations, often forcing programmers to choose different collection implementations for each task. Thus, changes to the program can invalidate the choice ...
