A JastAdd implementation of Oberon-0

The JastAdd system—combining declarative and imperative compiler implementation

We describe JastAdd, a Java-based system for compiler implementation. JastAdd is centered around an object-oriented representation of the abstract syntax tree where reference variables can be used to link together different parts of the tree. JastAdd supports the combination of declarative techniques (using Reference Attributed Grammars) and imperative techniques (using ordinary Java code) in i...

Development of a Modelica Compiler Using JastAdd

This paper describes experiences from implementing key parts of a compiler for Modelica, an object-oriented language supporting declarative modeling and simulation of complex physical systems. Our implementation uses the attribute-grammar based tool JastAdd. In particular, we discuss the implementation of Modelica name analysis which is highly context-dependent, type analysis which is based on ...

Oberon as an Implementation Language for COM Objects

This is a short report on a short project, carried out during a 3-month sabbatical stay at Microsoft Research in the fall of 1998. The motivation for this endeavor was doublefold: (a) verify the degree of language independence of the COM component technology and (b) explore COM as a potential commercial environment and framework for Oberon applications. The project finally converged towards a s...

Differences between Oberon and Oberon-2

Oberon–2 is a true extension of Oberon [1]. This paper summarizes the extensions and tries to shed some light on the motivations behind them. By that we hope to make it easier for the reader to classify Oberon–2. For details the reader is referred to the language report. One important goal for Oberon–2 was to make object–oriented programming easier without sacrificing the conceptual simplicity ...
