PADL 2014: Call for Papers
by Matthew Flatt 29 Jul '13

29 Jul '13

Call for Papers =============== 16th International Symposium on Practical Aspects of Declarative Languages (PADL 2014) http://www.ist.unomaha.edu/padl2014 San Diego, California, USA, January 20-21, 2014 Co-located with ACM POPL'14 Conference Description ====================== Declarative languages build on sound theoretical bases to provide attractive frameworks for application development. These languages have been successfully applied to many different real-world situations, ranging from data base management to active networks to software engineering to decision support systems. New developments in theory and implementation have opened up new application areas. At the same time, applications of declarative languages to novel problems raise numerous interesting research issues. Well-known questions include designing for scalability, language extensions for application deployment, and programming environments. Thus, applications drive the progress in the theory and implementation of declarative systems, and benefit from this progress as well. PADL is a forum for researchers and practitioners to present original work emphasizing novel applications and implementation techniques for all forms of declarative concepts, including, functional, logic, constraints, etc. Topics of interest include, but are not limited to: * Innovative applications of declarative languages * Declarative domain-specific languages and applications * Practical applications of theoretical results * New language developments and their impact on applications * Declarative languages and Software Engineering * Evaluation of implementation techniques on practical applications * Practical experiences and industrial applications * Novel uses of declarative languages in the classroom * Practical extensions such as constraint-based, probabilistic, and reactive languages. PADL'14 welcomes new ideas and approaches pertaining to applications and implementation of declarative languages. In this occasion PADL is co-located, as traditionally, with ACM POPL, which will be held immediately following PADL. The symposium will be held in San Diego, California, USA. Important Dates and Submission Guidelines ========================================= Abstract Submission: September 6, 2013 Paper Submission: September 13, 2013 Notification: October 21, 2013 Camera-ready: November 10, 2013 Symposium: January 20-21, 2014 Authors should submit an electronic copy of the full paper in PDF using the Springer LNCS format. The submission will be done through EasyChair conference system. If electronic submission is impossible, please contact the program chairs for information on how to submit hard copies. All submissions must be original work written in English. Submissions must be unpublished and not submitted for publication elsewhere. Work that already appeared in unpublished or informally published workshops proceedings may be submitted. PADL'14 will accept both technical and application papers: * Technical papers must describe original, previously unpublished research results. Technical papers must not exceed 16 pages in Springer LNCS format. * Application papers are a mechanism to present important practical applications of declarative languages that occur in industry or in areas of research other than Computer Science. Application papers will be published in the Springer-Verlag conference proceedings, and will be presented in a separate session. Application papers are expected to describe complex and/or real-world applications that rely on an innovative use of declarative languages. Application descriptions, engineering solutions and real-world experiences (both positive and negative) are solicited. The limit for application papers is 6 pages in Springer LNCS format.

New user (& Questions)
by Amirouche Boubekki 24 Jul '13

24 Jul '13

Héllo, A new user here, my name is Amirouche, I go by this name from the beginning of my life which is probably a short period of time but certainly not too much. I define myself has being primarly a Python dev. I do web (or related and sometimes silly) things but that's not what pays the bills. I came to Scheme and Gambit for its simplicity/minimalism, expressiveness, wisdom and also speed. Actually what triggered the need to try a LISP is a problem I encountered. I needed (or wanted) to keep the number of Python objects to a minimum while still maintaining maintainability and readability. But the thing is I'm jailed in the Python class system. I find myself fighting it to have the user API I want while still providing a clear inner architecture. For that matter, I use, so-called, advanced patterns like metaclasses and data descriptors which basically reduce maintainability because Python user seldom use them. Being less maintainable also means it's less pratical. What I believe is that LISP-like languages are easier to build DSL while still keeping the concepts and code pratical. I'm not sure how much this is True. That said, I also believe, the reason why LISP-like languages were forgotten from the industry is because every project is a new language, I don't know how much True this is either. I also assume that LISP coming from academia, is though to not be pragmatic. Python being in-between has a privileged position. Scheme having a small core, makes it I think more practical than LISP, somewhat easy to learn like Python. While still, making it possible to express problems and solutions in a clear, concise and efficient way. That said Scheme and Gambit in particular lakes documentation, except if SFRI are the documentation... Those are all assumptions that I want to check. Anyway, I tried to build Black Hole but it failed, I filled an issue<https://github.com/pereckerdal/blackhole/issues/50> . Is there any procedure reference page I can read ? or is it the R5RS ? See you around, Amirouche

Thanks, Nathan. The install goes just fine. However, when I try the first sample line, I get an error: (scm* [] (load "core")) *** ERROR IN "(no source)"@2.2 -- No such file or directory What advantages do you see using such to develop apps, particularly on the Android platform?

I might be able to help you here. You need Clojure and Leiningen working on your system for the initial bootstrap of clojure-scheme's compiler and standard library. Take a look at the latest git revision: https://github.com/takeoutweight/clojure-scheme ; there's now a README that shows the steps to get the sample Clojure repl working. You should have a "scm" directory with the compiled scheme code if things are working correctly. -Nathan Sorenson _______________________________________________ Gambit-list mailing list Gambit-list(a)iro.umontreal.ca https://webmail.iro.umontreal.ca/mailman/listinfo/gambit-list

Call for Papers PEPM 2014
by publicityifl＠gmail.com 17 Jul '13

17 Jul '13

Hello, Please, find below the first call for papers for PEPM 2014. Please forward these to anyone you think may be interested. Apologies for any duplicates you may receive. best regards, Jurriaan Hage Co-chair of PEPM 2014 ----------------------------- C A L L F O R P A P E R S ----------------------------- ======= PEPM 2014 =========== ACM SIGPLAN 2014 WORKSHOP ON PARTIAL EVALUATION AND PROGRAM MANIPULATION Mon-Tue, January 20-21, 2014 San Diego, California, USA co-located with POPL'14 Sponsored by ACM SIGPLAN http://www.program-transformation.org/PEPM14 SCOPE The PEPM Symposium/Workshop series aims at bringing together researchers and practitioners working in the areas of program manipulation, partial evaluation, and program generation. PEPM focuses on techniques, theory, tools, and applications of analysis and manipulation of programs. The 2014 PEPM workshop will be based on a broad interpretation of semantics-based program manipulation and continue last years' successful effort to expand the scope of PEPM significantly beyond the traditionally covered areas of partial evaluation and specialization and include practical applications of program transformations such as refactoring tools, and practical implementation techniques such as rule-based transformation systems. In addition, the scope of PEPM covers manipulation and transformations of program and system representations such as structural and semantic models that occur in the context of model-driven development. In order to reach out to practitioners, a separate category of tool demonstration papers will be solicited. Topics of interest for PEPM'14 include, but are not limited to: Program and model manipulation techniques such as: supercompilation, partial evaluation, fusion, on-the-fly program adaptation, active libraries, program inversion, slicing, symbolic execution, refactoring, decompilation, and obfuscation. Program analysis techniques that are used to drive program/model manipulation such as: abstract interpretation, termination checking, binding-time analysis, constraint solving, type systems, automated testing and test case generation. Techniques that treat programs/models as data objects including metaprogramming, generative programming, embedded domain-specific languages, program synthesis by sketching and inductive programming, staged computation, and model-driven program generation and transformation. Application of the above techniques including case studies of program manipulation in real-world (industrial, open-source) projects and software development processes, descriptions of robust tools capable of effectively handling realistic applications, benchmarking. Examples of application domains include legacy program understanding and transformation, DSL implementations, visual languages and end-user programming, scientific computing, middleware frameworks and infrastructure needed for distributed and web-based applications, resource-limited computation, and security. To maintain the dynamic and interactive nature of PEPM, we will continue the category of `short papers' for tool demonstrations and for presentations of exciting if not fully polished research, and of interesting academic, industrial and open-source applications that are new or unfamiliar. Student attendants with accepted papers can apply for a SIGPLAN PAC grant to help cover travel expenses and other support. 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 programme, see its web page. All accepted papers, short papers included, will appear in formal proceedings published by ACM Press. In addition to printed proceedings, accepted papers will be included in the ACM Digital Library. A special issue for Science of Computer Programming is planned with recommended papers from PEPM'14. PEPM has also established a Best Paper award. The winner will be announced at the workshop. SUBMISSION CATEGORIES AND GUIDELINES Regular Research Papers must not exceed 12 pages in ACM Proceedings style (including appendix). Tool demonstration papers and short papers must not exceed 6 pages in ACM Proceedings style (including appendix). At least one author of each accepted contribution must attend the workshop and present the work. In the case of tool demonstration papers, a live demonstration of the described tool is expected. Suggested topics, evaluation criteria, and writing guidelines for both research tool demonstration papers will be made available on the PEPM'14 Web-site. Papers should be submitted electronically via the workshop web site. Authors using LaTeX to prepare their submissions should use the new improved SIGPLAN proceedings style (sigplanconf.cls, 9pt template). IMPORTANT DATES Abstract due: Sat, September 28, 2013 Paper submission: Sat, October 5, 2013, 23:59, GMT Author notification: Mon, November 11, 2013 Camera-ready papers due: * to be announced * INVITED SPEAKERS to be announced PROGRAM CHAIRS Wei Ngan Chin (National University of Singapore, Singapore) Jurriaan Hage (Utrecht University, Netherlands) PROGRAM COMMITTEE velyne Contejean (LRI, CNRS, Universit Paris-Sud, France) Cristina David (University of Oxford, UK) Alain Frisch (LexiFi, France) Ronald Garcia (University of British Columbia, Canada) Zhenjiang Hu (National Institute of Informatics, Japan) Paul H J Kelly (Imperial College, UK) Oleg Kiselyov (Monterey, USA) Naoki Kobayashi (University of Tokyo, Japan) Jens Krinke (University College London, UK) Ryan Newton (University of Indiana, USA) Alberto Pardo (Universidad de la Repblica, Uruguay) Sungwoo Park (Pohang University of Science and Technology, South Korea) Tiark Rompf (Oracle Labs & EPFL, Switzerland) Sukyoung Ryu (KAIST, South Korea) Kostis Sagonas (Uppsala University, Sweden) Max Schaefer (Nanyang Technological University, Singapore) Harald S¿ndergaard (The University of Melbourne, Australia) Eijiro Sumii (Tohoku University, Japan) Eric Van Wyk (University of Minnesota, USA) Jeremy Yallop (University of Cambridge, UK)

The symposium is held from 28th to 30th of August 2013. Scope ----- The goal of the IFL symposia is to bring together researchers actively engaged in the implementation and application of functional and function-based programming languages. IFL 2013 will be a venue for researchers to present and discuss new ideas and concepts, work in progress, and publication-ripe results related to the implementation and application of functional languages and function-based programming. Following the IFL tradition, IFL 2013 will use a post-symposium review process to produce the formal proceedings which will be published in the ACM Digital Library. All participants of IFL 2013 are invited to submit either a draft paper or an extended abstract describing work to be presented at the symposium. At no time may work submitted to IFL be simultaneously submitted to other venues; submissions must adhere to ACM SIGPLAN's republication policy: http://www.sigplan.org/Resources/Policies/Republication The submissions will be screened by the program committee chair to make sure they are within the scope of IFL, and will appear in the draft proceedings distributed at the symposium. Submissions appearing in the draft proceedings are not peer-reviewed publications. Hence, publications that appear only in the draft proceedings do not count as publication for the ACM SIGPLAN republication policy. After the symposium, authors will be given the opportunity to incorporate the feedback from discussions at the symposium and will be invited to submit a revised full article for the formal review process. From the revised submissions, the program committee will select papers for the formal proceedings considering their correctness, novelty, originality, relevance, significance, and clarity. Invited Speaker --------------- Lennart Augustsson, currently employed by the Standard Chartered Bank, well-known for his work on Haskell, parallel Haskell, Cayenne, and Bluespec, is the invited speaker of IFL 2013.

Riaxpander on Gambit
by Matt Hastie 08 Jul '13

08 Jul '13

Hello Gambit People, I've been hacking away at riaxpander, and now have it at the point where it runs in native gambit. It can compile Alex Shinn's matchable library and run the matchable unit tests - that's the net testing thus far! Credit here goes to Taylor R. Campbell, for creating such a very nice and powerful expander. My contribution was to: - extract riaxpander-gambit.scm from the tmp directory on Campbell's website, - vandalize the source to support case sensitivity (lower case all macrology patterns), - figure out the problems that prohibit gambit compile-file from working, - add some dark meat from the chicken to support loading of macros in compiled source, and - add a cond-expand classifier that works when syntax-case appears in a non-evaluated feature clause. Line numbers and decent error messages are inoperative at this time. I also haven't examined which scheme flavor the macrologies define. I'm not certain how much gambitism is there. My personal plan is to keep hacking away towards r7rs and/or a module system (r7rs define-library) ... but these are indeed lofty goals. I am already out of my depth, deep in the lambdas. Source code is in: https://github.com/matthastie/riaxpander Kind Regards, Matt Hastie.

Mixing internal defines and expressions
by Nathan Sorenson 07 Jul '13

07 Jul '13

I've noticed that Gambit seems to require all internal definitions to be at the top of a body. It will give "Ill-placed 'define'" otherwise. Other Scheme implementations seem to allow interleaving definitions and expressions as long as the last form of a body is an expression. The reason I care about this is that sometimes test code in Clojure involves wrapping an entire file in a top-level function which is called to run the tests. If there are assert statements between function definitions, I will cause a "Ill-placed 'define'" error. This isn't really common, but it is done in the ClojureScript tests for example. In some cases I imagine I could tree-walk the forms and lift any nested definitions to the top-level to manually forward-declare them, and then replace the internal definitions with set!... but I'd like to avoid such non-local code transformations if possible. Another option would be to unwind all lets and lambdas so each body only can contain one expression, such that (let () 1 (define two 2) two) => (let () 1 (let () (two 2) two)) Not sure off-hand if this approach would have any downsides w.r.t. the compiled code? Are there any other avenues I could explore to allow this interleaving to be expressed in Gambit?
