Comparing Static Semantics Specifications for the IceDust DSL: A Case Study of Statix

Reusable tools for engineering software languages can bridge the gap between formal specification and implementation, lowering the bar for engineers to design and implement programming languages. Among such tools belong NaBL2 and its successor Statix, which are meta-languages for declaratively specifying the static semantics of programming...

Modernizing the WebDSL Front-End: A Case Study in SDF3 and Statix

The front-end of a compiler reads the source program and performs analyses such as type checking. The goal of the front-end is to check for the presence of syntactic and semantic errors before the program is passed to the back-end of the compiler for tasks such as optimization and code generation.<br/><br/>WebDSL is a domain-specific language...

Function Inlining as a Language Parametric Refactoring

Refactorings are program transformations that preserve the observable behavior of the program. The refactoring function inlining replaces a function call with the contents of the referenced function definition. To preserve the behavior, properties such as reference relations must be retained and language constructs like 'return' statements must...

Composable Type System Specification using Heterogeneous Scope Graphs

Static Analysis is of indispensable value for the robustness of software systems and the efficiency of developers. Moreover, many modern-day software systems are composed of interacting subsystems written in different programming languages. However, in most cases no static validation of these interactions is applied. In this thesis, we identify...
