This paper presents K-Java, a complete executable formal semantics of Java 1.4. K-Java
was extensively tested with a test suite developed alongside the project, following the Test …

Delta-oriented programming is a compositional approach to flexibly implementing software
product lines. A product line is represented by a code base and a product line declaration …

The term traits is overloaded in the literature. In this work we refer to traits as the stateless
model and implementation described in Schaerli et al. articles. Traits provide a flexible way …

Many dynamically-typed languages (including JavaScript, Ruby, Python or Racket) support
first-class classes, or related concepts such as first-class traits and/or mixins. In those …

We present a new variation of object-oriented programming built around three simple and
orthogonal constructs: classes for storing object state, interfaces for expressing object types …

This paper presents a unified model for two complementary approaches of code reuse:
Traits and Delta-Oriented Programming (DOP). Traits are used to modularly construct …

We demonstrate that traits are a natural way to support correctness-by-construction (CbC) in
an existing programming language in the presence of traditional post-hoc verification (PhV) …

In this paper we present Xsemantics, a DSL for writing type systems, reduction rules and in
general relation rules for languages implemented in Xtext. Xsemantics aims at minimizing …

Traits have been proposed as a more flexible mechanism than class inheritance for
structuring code in object-oriented programming, to achieve fine-grained code reuse. A trait …

Correctness-by-Construction (CbC) is an incremental program construction process to
construct functionally correct programs. The programs are constructed stepwise along with a …
