CALL FOR PAPERS 7th Workshop on Reactive and Event-based Languages and Systems (REBLS 2020) co-located with the SPLASH Conference Chicago, Illinois, USA Sun 15 - Fri 20 November 2020 Website: https://2020.splashcon.org/home/rebls-2020 IMPORTANT DATES Submission Deadline: 24 Jul 2020 Author Notification: 24 Aug 2020 Final Submission Deadline: 25 Sep 2020 INTRODUCTION Reactive programming and event-based programming are two closely related programming styles that are becoming more important with the ever increasing requirement for applications to run on the web or on mobile devices, and the advent of advanced High-Performance Computing (HPC) technology. A number of publications on middleware and language design -- so-called reactive and event-based languages and systems (REBLS) -- have already seen the light, but the field still raises several questions. For example, the interaction with mainstream language concepts is poorly understood, implementation technology is still lacking, and modularity mechanisms remain largely unexplored. Moreover, large applications are still to be developed, and, consequently, patterns and tools for developing large reactive applications are still in their infancy. This workshop will gather researchers in reactive and event-based languages and systems. The goal of the workshop is to exchange new technical research results and to better define the field by developing taxonomies and discussing overviews of the existing work. We welcome all submissions on reactive programming, functional reactive programming, and event- and aspect- oriented systems, including but not limited to: * Language design, implementation, runtime systems, program analysis, software metrics, patterns and benchmarks. * Formal models for reactive and event-based programming. * Study of the paradigm: interaction of reactive and event-based programming with existing language features such as object-oriented programming, pure functional programming, mutable state, concurrency. * Modularity and abstraction mechanisms in large systems. * Advanced event systems, event quantification, event composition, aspect-oriented programming for reactive applications. * Functional Reactive Programming (FRP), self-adjusting computation and incremental computing. * Synchronous languages, modeling real-time systems, safety-critical reactive and embedded systems. * Applications, case studies that show the efficacy of reactive programming. * Empirical studies that motivate further research in the field. * Patterns and best-practices. * Related fields, such as complex event processing, reactive data structures, view maintenance, constraint-based languages, and their integration with reactive programming. * Implementation technology, language runtimes, virtual machine support, compilers. * IDEs, Tools. The format of the workshop is that of a mini-conference. Participants can present their work in slots of 30 mins with Q&A included. Because of the declarative nature of reactive programs, it is often hard to understand their semantics just by looking at the code. We therefore also encourage authors to use their slots for presenting their work based on live demos. SUBMISSIONS REBLS encourages submissions of two types of papers: * Full papers: papers that describe complete research results. These papers will be published in the ACM digital library. * In-progress papers: papers that have the potential of triggering an interesting discussion at the workshop or present new ideas that require further systematic investigation. These papers will not be published in the ACM digital library. Format: * Submissions should use the ACM SIGPLAN Conference acmart Format with the two-column, sigplan Subformat, 10 point font, using Biolinum as sans-serif font and Libertine as serif font. All submissions should be in PDF format. If you use LaTeX or Word, please use the ACM SIGPLAN acmart Templates. The page http://www.sigplan.org/Resources/Author/#acmart-format contains instructions for authors, and a package that includes an example file acmart-sigplan.tex. * Authors are required to explicitly specify the type of paper in the submission (i.e., full paper, in-progress paper). * Full papers can be *up to* 12 pages in length, excluding references. In-progress papers can be *up to* 6 pages, excluding references. Papers do not need to make use of all pages, but they will be summarily rejected if they exceed the page limits. Instructions for the Authors: * Papers should be submitted through: https://rebls20.hotcrp.com/ * For fairness reasons, all submitted papers should conform to the formatting instructions. Submissions that violate these instructions will be summarily rejected. * Program Committee members are allowed to submit papers, but their papers will be held to a higher standard. * Papers must describe unpublished work that is not currently submitted for publication elsewhere as described by SIGPLAN’s Republication Policy (http://www.sigplan.org/Resources/Policies/Republication). Submitters should also be aware of ACM’s Policy and Procedures on Plagiarism. * All submissions are expected to comply with the ACM Policies for Authorship detailed at https://www.acm.org/publications/authors/information-for-authors.
