Technical, practice, and application papers related to Erlang, BEAM, Elixir, Scala/Akka, CloudHaskell, Lisp Flavoured Erlang, OCaml, and functional programming are welcome and encouraged. *LAST CALL FOR PAPERS* Eighteenth ACM SIGPLAN Erlang Workshop https://icfp19.sigplan.org/home/erlang-2019 Berlin, Germany, 18 August 2019 Satellite event of the 24th ACM SIGPLAN International Conference on Functional Programming (ICFP 2019) 18 - 23 August, 2019 The Erlang Workshop aims to bring together the open source, academic, and industrial communities of Erlang, to discuss technologies and languages related to Erlang. The Erlang model of concurrent programming has been widely emulated, for example by Akka in Scala, and even new programming languages were designed atop of the Erlang VM, such as Elixir. Therefore we would like to broaden the scope of the workshop to include systems like those mentioned above. The workshop will enable participants to familiarize themselves with recent developments on new techniques and tools, novel applications, draw lessons from users' experiences and identify research problems and common areas relevant to the practice of Erlang, Erlang-like languages, functional programming, distribution, concurrency etc. We invite two types of submissions. 1. Technical papers describing language extensions, critical discussions of the status quo, formal semantics of language constructs, program analysis and transformation, virtual machine extensions and compilation techniques, implementations and interfaces of Erlang in/with other languages, and new tools (profilers, tracers, debuggers, testing frameworks, etc.). Submission related to Erlang, Elixir, Scala/Akka, CloudHaskell, Lisp Flavoured Erlang, OCaml, and functional programming are welcome and encouraged. The maximum length for technical papers is restricted to 12 pages, but short papers (max. 6 pages) are welcomed as well. 2. Practice and application papers describing uses of Erlang in the "real-world", Erlang libraries for specific tasks, experiences from using Erlang in specific application domains, reusable programming idioms and elegant new ways of using Erlang to approach or solve a particular problem. The maximum length for the practice and application papers is restricted to 12 pages, but short papers (max. 6 pages) are welcomed as well. *Workshop Co-Chairs* Adrian Francalanza, University of Malta, Malta Viktória Fördős, Cisco Systems, Sweden *Program Committee* (Note: the Workshop Co-Chairs are also committee members) Annette Bieniusa, University of Kaiserslautern, Germany Christopher S.

The submission page is https://erlang19.hotcrp.com Submitted papers should be in portable document format (PDF), formatted using the ACM SIGPLAN style guidelines. Each submission must adhere to SIGPLAN's republication policy. Violation risks summary rejection of the offending submission. Accepted papers will be published by the ACM and will appear in the ACM Digital Library. The proceedings will be freely available for download from the ACM Digital Library from one week before the start of the conference until two weeks after the conference. Paper submissions will be considered for poster submission in the case they are not accepted as full papers. *Venue & Registration Details* For registration, please see the ICFP 2019 web site at: http://icfp19.sigplan.org/ *Related Links* ICFP 2019 web site: http://icfp19.sigplan.org/ Past ACM SIGPLAN Erlang workshops: http://www.erlang.org/workshop/ Open Source Erlang: http://www.erlang.org/ HotCRP submission site: https://erlang19.hotcrp.com Author Information for SIGPLAN Conferences: http://www.sigplan.org/authorInformation.htm Attendee Information for SIGPLAN Events: http://www.sigplan.org/Resources/Policies/CodeOfConduct/
