Seminar from Paul Klint

Wednesday 4th May, 2016 – GSSI – Main Room  (9.30 – 12.00)

Title: The Evolving Rascal Ecosystem
Slides: Here 
Abstract:

The Rascal language and ecosystem aim at providing a one-stop shop for metaprogramming:
parsing, analysis, transformation, and code generation are conveniently provided in
a single linguistic framework. In this talk I will first recapitulate the global design
of the Rascal language and some of its applications. Next, I will focus on the Rascal
implementation and will compare the current, interpreted-based, implementation and the
upcoming Rascal compiler that compiles to the JVM, making Rascal a full-blown JVM language.
Two of the more important concepts in the compiler are intermediate languages and coroutines.
Defining and transforming languages is Rascal’s core business, so it is no surprise that introducing
intermediate languages in the compiler is straightforward and helps to reduce complexity.
Asymmetric, stackfull, coroutines form the basis for the compilation of Rascal’s pattern matching.
They will be discussed in some detail. A quick summary of future plans will conclude the presentation.
