Apologies for any duplicates! CALL FOR PAPERS 4th International Workshop on Real World Domain Specific Languages https://sites.google.com/site/realworlddsl In conjunction with The International Symposium on Code Generation and Optimisation 2019. http://cgo.org/cgo2019/ Washington DC, USA, 16th February, 2019 As the use of computers proliferates, the complexity and variety of systems continues to grow. As a result, it is becoming increasingly inflexible to "hard wire” behaviours into software. Software developers can enable more control over their software configurations by exploiting Domain Specific Languages (DSLs). Such DSLs provide a systematic way to structure the underlying computational components: to coin a phrase, a DSL is a library with syntax. There is an enormous variety of DSLs for a very wide range of domains. Most DSLs are highly idiosyncratic, reflecting both the specific natures of their application domains and their designers’ own preferences. This workshop will bring together constructors of DSLs for “real world” domains; that is, DSLs intended primarily to aid in building software to solve real world problems rather than to explore the more theoretical aspects of language design and implementation. We are looking for submissions that present the motivation, design, implementation, use and evaluation of such DSLs. Previous workshops were RWSDL’16 (Barcelona), RWDSL’17 (Austin) and RWDSL’18 (Vienna), all collocated with CGO and published in the ACM Digital Library. Key Dates: Paper submission deadline: 9th November 2018 Author notification: 7th December 2018 Final manuscript due: 11th January 2019 Workshop: 16th February 2019 Submission Instructions: The EasyChair submission page for this workshop is: https://easychair.org/conferences/?conf=rwdsl19 Accepted submissions will be published in the ACM Digital Library within its International Conference Proceedings Series. Submissions should be 8-10 pages in ACM double-column format. Authors should follow the information for formatting ACM SIGPLAN conference papers, which can be found at http://www.acm.org/publications/proceedings-template. Full submission details are on the workshop web page.
