Generic programs often embody non-traditional kinds of polymorphism; ordinary programs are obtained from them by suitably instantiating their parameters. In contrast with normal programs, the parameters of a generic program are often quite rich in structure; for example they may be other programs, types or type constructors, class hierarchies, or even programming paradigms. Generic programming techniques have always been of interest, both to practitioners and to theoreticians, and, for at least 20 years, generic programming techniques have been a specific focus of research in the functional and object-oriented programming communities. Generic programming has gradually spread to more and more mainstream languages, and today is widely used in industry. This workshop brings together leading researchers and practitioners in generic programming from around the world, and features papers capturing the state of the art in this important area. We welcome contributions on all aspects, theoretical as well as practical, of * generic programming, * programming with (C++) concepts, * meta-programming, * programming with type classes, * programming with modules, * programming with dependent types, * type systems for generic programming, * polytypic programming, * adaptive object-oriented programming, * component-based programming, * strategic programming, * aspect-oriented programming, * family polymorphism, * object-oriented generic programming, * implementation of generic programming languages, * static and dynamic analyses of generic programs, * and so on. Program Committee ----------------- * Patrick Bahr (co-chair), University of Copenhagen * Sebastian Erdweg (co-chair), Technical University of Darmstadt * Edwin Brady, University of St Andrews * Edsko de Vries, Well-Typed LLP * Mauro Jaskelioff, National University of Rosario * Johan Jeuring, Utrecht University * Pieter Koopman, Radboud University Nijmegen * Bruno C. d. S. Oliveira, University of Hong Kong * Nicolas Pouillard, IT University of Copenhagen * Sukyoung Ryu, Korea Advanced Institute of Science and Technology * Sibylle Schupp, Hamburg University of Technology * Sam Tobin-Hochstadt, Indiana University Proceedings and Copyright ------------------------- We plan to have formal proceedings, published by the ACM. Accepted papers will be included in the ACM Digital Library. Authors must grant ACM publication rights upon acceptance (<a href="http://authors.acm.org/main.html" target="_blank">http://authors.acm.org/main.html</a>), but may retain copyright if they wish. Authors are encouraged to publish auxiliary material with their paper (source code, test data, and so forth). 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. Submission details ------------------ * Submission deadline: Fri, 15th May 2015 * Author notification: Fri, 26th June 2015 * Final version due: Sun, 19th July 2015 * Workshop: Sun, 30th August 2015 Submitted papers should fall into one of two categories: * Regular research papers (12 pages) * Short papers: case studies, tool demos, generic pearls (6 pages) Regular research papers are expected to present novel and interesting research results. Short papers need not present novel or fully polished results. Good candidates for short papers are those that report on interesting case studies of generic programming in open source or industry, present demos of generic programming tools or libraries, or discuss elegant and illustrative uses of generic programming ('pearls'). All submissions should be in portable document format (PDF), formatted using the ACM SIGPLAN style guidelines (two-column, 9pt). Regular research papers must not exceed 12 pages. Short papers must not exceed 6 pages. If applicable, papers should be marked with one of the labels 'case study, 'tool demo' or 'generic pearl' in the title at the time of submission. Papers should be submitted via HotCRP at <a href="https://icfp-wgp15.hotcrp.com/" target="_blank">https://icfp-wgp15.hotcrp.com/</a> Travel Support -------------- Student attendees with accepted papers can apply for a SIGPLAN PAC grant to help cover travel expenses. PAC also offers other support, such as for child-care expenses during the meeting or for travel costs for companions of SIGPLAN members with physical disabilities, as well as for travel from locations outside of North America and Europe. For details on the PAC program, see its web page (<a href="http://www.sigplan.org/PAC.htm" target="_blank">http://www.sigplan.org/PAC.htm</a>). History of the Workshop on Generic Programming ---------------------------------------------- Earlier Workshops on Generic Programming have been held in * Gothenburg, Sweden 2014 (affiliated with ICFP), * Boston, Massachusetts, US 2013 (affiliated with ICFP), * Copenhagen, Denmark 2012 (affiliated with ICFP), * Tokyo, Japan 2011 (affiliated with ICFP), * Baltimore, Maryland, US 2010 (affiliated with ICFP), * Edinburgh, UK 2009 (affiliated with ICFP), * Victoria, BC, Canada 2008 (affiliated with ICFP), * Portland 2006 (affiliated with ICFP), * Ponte de Lima 2000 (affiliated with MPC), * Marstrand 1998 (affiliated with MPC). Furthermore, there were a few informal workshops * Utrecht 2005 (informal workshop), * Dagstuhl 2002 (IFIP WG2.1 Working Conference), * Nottingham 2001 (informal workshop). There were also (closely related) DGP workshops in Oxford (June 3-4 2004), and a Spring School on DGP in Nottingham (April 24-27 2006, which had a half-day workshop attached).
