A Calculus for Variational Programming

Authors: Sheng Chen, Martin Erwig, and Eric Walkingshaw

Published in: LIPIcs, Volume 56, 30th European Conference on Object-Oriented Programming (ECOOP 2016)

Abstract
Variation is ubiquitous in software. Many applications can benefit from making this variation explicit, then manipulating and computing with it directly---a technique we call "variational programming". This idea has been independently discovered in several application domains, such as efficiently analyzing and verifying software product lines, combining bounded and symbolic model-checking, and computing with alternative privacy profiles. Although these domains share similar core problems, and there are also many similarities in the solutions, there is no dedicated programming language support for variational programming. This makes the various implementations tedious, prone to errors, hard to maintain and reuse, and difficult to compare. In this paper we present a calculus that forms the basis of a programming language with explicit support for representing, manipulating, and computing with variation in programs and data. We illustrate how such a language can simplify the implementation of variational programming tasks. We present the syntax and semantics of the core calculus, a sound type system, and a type inference algorithm that produces principal types.

Domain-Specific Languages (Dagstuhl Seminar 15062)

Authors: Sebastian Erdweg, Martin Erwig, Richard F. Paige, and Eelco Visser

Published in: Dagstuhl Reports, Volume 5, Issue 2 (2015)

Abstract
This report documents the program and outcomes of Dagstuhl Seminar 15062 “Domain-Specific Languages”, which took place February 1-6, 2015. The seminar was motivated on the one hand by the high interest in domain-specific languages in academia and industry and on the other hand by the observation that the community is divided into largely disconnected subdisciplines (e.g., internal, external, visual, model-driven). The seminar included participants across these subdisciplines and included overview talks, technical talks, demos, discussion groups, and an industrial panel. This report collects the abstracts of talks and other activities at the seminar and summarizes the outcomes of the seminar.

Exploiting Domain-Specific Structures For End-User Programming Support Tools

Authors: Robin Abraham and Martin Erwig

Published in: Dagstuhl Seminar Proceedings, Volume 7081, End-User Software Engineering (2007)

Abstract
In previous work we have tried to transfer ideas that have been successful in general-purpose programming languages and mainstream software engineering into the realm of spreadsheets, which is one important example of an end-user programming environment. More specifically, we have addressed the questions of how to employ the concepts of type checking, program generation and maintenance, and testing in spreadsheets. While the primary objective of our work has been to offer improvements for end-user productivity, we have tried to follow two particular principles to guide our research. (1) Keep the number of new concepts to be learned by end users at a minimum. (2) Exploit as much as possible information offered by the internal structure of spreadsheets. In this short paper we will illustrate our research approach with several examples.
