Scala 3 syntax rewriting

Mark Tropin

We present syntax rewriting rules that translate Scala 2 code into Scala 3. Two major syntactic changes are introduced: new control structure syntax and significant indentation. We describe the design and the implementation of these rules and evaluate thei ...

Immediate Tracing

Valentin Aebi

This semester project report describes a prototype tracing tool that records the behavior of a Java program during its execution. It explains the two methods that were attempted to implement the tool, one using the Java debug interface, which gave poor res ...

Optimizing Java on Truffle

Ekaterina Goltsova

Java on Truffle is an early-stage implementation of a Java Virtual Machine in Java. So far its development has focused on compatibility and functionality, not addressing performance in a systematic way. This thesis presents a series of experiments on Java ...

Just-in-time performance without warm-up

Denys Shabalin

Scala has been developed as a language that deeply integrates with the Java ecosystem. It offers seamless interoperability with existing Java libraries. Since the Scala compiler targets Java bytecode, Scala programs have access to high-performance runtimes ...

Safe initialization of objects

Fengyun Liu

The inception of object-oriented programming introduces a category of bugs related to object construction: initialization errors. Every newly created object goes through several initialization states: starting from a state where all fields are uninitialize ...

EPFL2020

Programming languages are increasingly compiled to multiple runtimes, each featuring their own rich structures such as their object model. Furthermore, they need to interact with other languages targeting said runtimes. A language targeting only one runtim ...

Cross-Platform Language Design in Scala.js (Keynote)

Sébastien Jean R Doeraene

Have you ever wondered what is the secret sauce of Scala.js? What defines Scala.js, above all else, is the overarching will to make it cross-platform. A cross-platform language is both portable-most source code cross-compiles and behaves the same way on mu ...

Correct Transformation of High-Level Models into Time-Triggered Implementations

Simon Bliudze

A number of component-based frameworks have been proposed to tackle the complexity of the design of concurrent software and systems and, in particular, to allow modelling and simulation of critical embedded applications. Such design frameworks usually prov ...

Java and Scala's Type Systems are Unsound The Existential Crisis of Null Pointers

Nada Amin

We present short programs that demonstrate the unsoundness of Java and Scala's current type systems. In particular, these programs provide parametrically polymorphic functions that can turn any type into any type without (down) casting. Fortunately, parame ...
