Abstract Language workbenches are tools that provide high-level mechanisms for the
implementation of (domain-specific) languages. Language workbenches are an active area …

The theory of context-free languages is well-understood and context-free parsers can be
used as off-the-shelf tools in practice. In particular, to use a context-free parser framework, a …

Extensible programming languages such as SugarJ or Racket enable programmers to
introduce customary language features as extensions of the base language. Traditionally …

Most programming languages are designed for general-purpose software development in a
one-size-fits-all fashion: They provide the same set of language features and constructs for …

Language extensions introduce high-level programming constructs that protect
programmers from low-level details and repetitive tasks. For such an abstraction barrier to …

General-purpose programming languages typically define literal notation for only a small
number of common data structures, like lists. This is unsatisfying because there are many …

When writing transformation systems, a significant amount of engineering effort goes into
setting up the infrastructure needed to direct individual transformations to specific targets in …

We present λ L, a statically typed lambda-calculus with languages as first-class citizens. In λ
L, languages can be defined and used to execute programs and, furthermore, they also can …

A key problem in metaprogramming and specifically in generative programming is to
guarantee that generated code is well-formed with respect to the context-free and context …

Abstract Implementing Programming Languages (PLs) has always been a challenge for
various reasons. One reason is the excess of routine tasks to be redone on every …
