Educational Programming Languages and Systems (Dagstuhl Seminar 22302)

Authors: Neil Brown, Mark J. Guzdial, Shriram Krishnamurthi, and Jens Mönig

Published in: Dagstuhl Reports, Volume 12, Issue 7 (2023)

Abstract
Programming languages and environments designed for educating beginners should be very different from those designed for professionals. Languages and environments for professionals are usually packed with complex powerful features, with a focus on productivity and flexibility. In contrast, those designed for beginners have quite different aims: to reduce complexity, surprise, and frustration. Designing such languages and environments requires a mix of skills. Obviously, some knowledge of programming language issues (semantics and implementation) is essential. But the designer must also take into account human-factors aspects (in the syntax, development environment, error messages, and more), cognitive aspects (in picking features, reducing cognitive load, and staging learning), and educational aspects (making the language match the pedagogy). In short, the design process is a broad and interdisciplinary problem. In this Dagstuhl Seminar we aimed to bring together attendees with a wide variety of expertise in computer education, programming language design and human-computer interaction. Because of the diverse skills and experiences needed to create effective solutions, we learned from each other about the challenges - and some of the solutions - that each discipline can provide. Our goal was that attendees could come and tell others about their work and the interesting challenges that they face - and solutions that they have come up with. We aimed to distill lessons from the differing experiences of the attendees, and record the challenges that we jointly face. The seminar allowed attendees to share details of their work with each other, followed by discussions, and finally some plenary sessions to summarize and record this shared knowledge.

Notional Machines and Programming Language Semantics in Education (Dagstuhl Seminar 19281)

Authors: Mark Guzdial, Shriram Krishnamurthi, Juha Sorva, and Jan Vahrenhold

Published in: Dagstuhl Reports, Volume 9, Issue 7 (2020)

Abstract
A formal semantics of a language serves many purposes. It can help debug the language's design, be used to prove type soundness, and guide optimizers to confirm that their work is correctness-preserving. Formal semantics are evaluated by several criteria: full abstraction, adequacy, soundness and completeness, faithfulness to an underlying implementation, and so on. Unfortunately, we know relatively little about how non-experts, such as students, actually employ a semantics. Which models are they able to grasp? How useful are these as they explain or debug programs? How does their use of models evolve with the kinds of programs they write? And does studying these kinds of questions yield any new insights into forms of semantics? This Dagstuhl Seminar intended to bridge this gap. It brought together representatives of the two communities-who usually travel in non-intersecting circles-to enable mutual understanding and cross-pollination. The Programming Languages community uses mathematics and focuses on formal results; the Computing Education Research community uses social science methods and focuses on the impact on humans. Neither is superior: both are needed to arrive at a comprehensive solution to creating tools for learning.

From Macros to DSLs: The Evolution of Racket

Authors: Ryan Culpepper, Matthias Felleisen, Matthew Flatt, and Shriram Krishnamurthi

Published in: LIPIcs, Volume 136, 3rd Summit on Advances in Programming Languages (SNAPL 2019)

Abstract
The Racket language promotes a language-oriented style of programming. Developers create many domain-specific languages, write programs in them, and compose these programs via Racket code. This style of programming can work only if creating and composing little languages is simple and effective. While Racket’s Lisp heritage might suggest that macros suffice, its design team discovered significant shortcomings and had to improve them in many ways. This paper presents the evolution of Racket’s macro system, including a false start, and assesses its current state.

The Next 700 Semantics: A Research Challenge

Authors: Shriram Krishnamurthi, Benjamin S. Lerner, and Liam Elberty

Published in: LIPIcs, Volume 136, 3rd Summit on Advances in Programming Languages (SNAPL 2019)

Abstract
Modern systems consist of large numbers of languages, frameworks, libraries, APIs, and more. Each has characteristic behavior and data. Capturing these in semantics is valuable not only for understanding them but also essential for formal treatment (such as proofs). Unfortunately, most of these systems are defined primarily through implementations, which means the semantics needs to be learned. We describe the problem of learning a semantics, provide a structuring process that is of potential value, and also outline our failed attempts at achieving this so far.

Teaching Programming Languages by Experimental and Adversarial Thinking

Authors: Justin Pombrio, Shriram Krishnamurthi, and Kathi Fisler

Published in: LIPIcs, Volume 71, 2nd Summit on Advances in Programming Languages (SNAPL 2017)

Abstract
We present a new approach to teaching programming language courses. Its essence is to view programming language learning as a natural science activity, where students probe languages experimentally to understand both the normal and extreme behaviors of their features. This has natural parallels to the "security mindset" of computer security, with languages taking the place of servers and other systems. The approach is modular (with minimal dependencies), incremental (it can be introduced slowly into existing classes), interoperable (it does not need to push out other, existing methods), and complementary (since it introduces a new mode of thinking).

Programming Language Techniques for Incremental and Reactive Computing (Dagstuhl Seminar 16402)

Authors: Camil Demetrescu, Sebastian Erdweg, Matthew A. Hammer, and Shriram Krishnamurthi

Published in: Dagstuhl Reports, Volume 6, Issue 10 (2017)

Abstract
Incremental computations are those that process input changes faster than naive computation that runs from scratch, and reactive computations consist of interactive behavior that varies over time. Due to the importance and prevalence of incremental, reactive systems, ad hoc variants of incremental and reactive computation are ubiquitous in modern software systems. In response to this reality, the PL research community has worked for several decades to advance new languages for systems that interface with a dynamically-changing environment. In this space, researchers propose new general-purpose languages and algorithms to express and implement efficient, dynamic behavior, in the form of incremental and reactive language systems. While these research lines continue to develop successfully, this work lacks a shared community that synthesizes a collective discussion about common motivations, alternative techniques, current results and future challenges. To overcome this lack of community, this seminar will work towards building one, by strengthening existing research connections and by forging new ones. Developing a shared culture is critical to the future advancement of incremental and reactive computing in modern PL research, and in turn, this PL research is critical to developing the efficient, understandable interactive systems of the future.

Human-Centric Development of Software Tools (Dagstuhl Seminar 15222)

Authors: Andrew J. Ko, Shriram Krishnamurthi, Gail C. Murphy, and Janet Siegmund

Published in: Dagstuhl Reports, Volume 5, Issue 5 (2016)

Abstract
Over two and half days, over 30 participants engaged in inventing and evaluating programming and software engineering tools from a human rather than tool perspective. We discussed methods, theories, recruitment, research questions, and community issues such as methods training and reviewing. This report is a summary of the key insights generated in the workshop.

The Racket Manifesto

Authors: Matthias Felleisen, Robert Bruce Findler, Matthew Flatt, Shriram Krishnamurthi, Eli Barzilay, Jay McCarthy, and Sam Tobin-Hochstadt

Published in: LIPIcs, Volume 32, 1st Summit on Advances in Programming Languages (SNAPL 2015)

Abstract
The creation of a programming language calls for guiding principles that point the developers to goals. This article spells out the three basic principles behind the 20-year development of Racket. First, programming is about stating and solving problems, and this activity normally takes place in a context with its own language of discourse; good programmers ought to formulate this language as a programming language. Hence, Racket is a programming language for creating new programming languages. Second, by following this language-oriented approach to programming, systems become multi-lingual collections of interconnected components. Each language and component must be able to protect its specific invariants. In support, Racket offers protection mechanisms to implement a full language spectrum, from C-level bit manipulation to soundly typed extensions. Third, because Racket considers programming as problem solving in the correct language, Racket also turns extra-linguistic mechanisms into linguistic constructs, especially mechanisms for managing resources and projects. The paper explains these principles and how Racket lives up to them, presents the evaluation framework behind the design process, and concludes with a sketch of Racket's imperfections and opportunities for future improvements.

Scripting Languages and Frameworks: Analysis and Verification (Dagstuhl Seminar 14271)

Authors: Fritz Henglein, Ranjit Jhala, Shriram Krishnamurthi, and Peter Thiemann

Published in: Dagstuhl Reports, Volume 4, Issue 6 (2015)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 14271 "Scripting Languages and Frameworks: Analysis and Verification". The seminar brought together a broad spectrum of researchers working on the semantics, analysis and verification of scripting languages. In addition to talks describing the latest problems and research on the key issues, split roughly into four overarching themes: semantics, types, analysis, contracts, languages, and security, the seminar had breakout sessions devoted to crosscutting topics that were of broad interest across the community, including, how to create shared analysis infrastructure, how to think about the semantics of contracts and blame, and the role of soundness in analyzing real world languages, as well as several "tutorial" sessions explaining various new tools and techniques.

Foundations for Scripting Languages (Dagstuhl Seminar 12011)

Authors: Robert Hirschfeld, Shriram Krishnamurthi, and Jan Vitek

Published in: Dagstuhl Reports, Volume 2, Issue 1 (2012)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 12011 on the ``Foundations for Scripting Languages''. The choice of ``for'' rather than ``of'' is intentional: it is our thesis that scripting languages are in need of foundations to support their extensive use but lack them, and we hope this event consolidated and advanced the state of the art in this direction.
