CALL FOR TUTORIAL PROPOSALS ICFP 2018 23rd ACM SIGPLAN International Conference on Functional Programming September 23-29, 2018 St. Louis, Missouri, United States http://conf.researchr.org/home/icfp-2018 The 23rd ACM SIGPLAN International Conference on Functional Programming will be held in St. Louis, Missouri, United States on September 23-29, 2018. ICFP provides a forum for researchers and developers to hear about the latest work on the design, implementations, principles, and uses of functional programming. Proposals are invited for tutorials to be presented during ICFP and its co-located workshops and other events. These tutorials are the successor to the CUFP tutorials from previous years, but we also welcome tutorials whose primary audience is researchers rather than practitioners. Tutorials may focus either on a concrete technology or on a theoretical or mathematical tool. Ideally, tutorials will have a concrete result, such as "Learn to do X with Y" rather than "Learn language Y". Tutorials may occur in parallel to both ICFP and its co-located workshops, from September 23 through September 29. Additionally, ICFP is co-located with Strange Loop this year, and this will be taken into account when scheduling tutorials. ---------------------------------------------------------------------- Submission details Deadline for submission: April 9, 2018 Notification of acceptance: April 16, 2018 Prospective organizers of tutorials are invited to submit a completed tutorial proposal form in plain text format to the ICFP 2018 workshop co-chairs (Christophe Scholliers and David Christiansen), via email to icfp-workshops-2018(a)googlegroups.com by April 9, 2018. Please note that this is a firm deadline. Organizers will be notified if their event proposal is accepted by April 16, 2018. The proposal form is available at: http://www.icfpconference.org/icfp2018-files/icfp18-tutorials-form.txt ---------------------------------------------------------------------- Selection committee The proposals will be evaluated by a committee comprising the following members of the ICFP 2018 organizing committee.

1st CfP: IFL 2018 (30th Symposium on Implementation and Application of Functional Languages)
by Jurriaan Hage 13 Mar '18

13 Mar '18

Hello, Please, find below the first call for papers for IFL 2018. Please forward these to anyone you think may be interested. Apologies for any duplicates you may receive. best regards, Jurriaan Hage Publicity Chair of IFL --- ================================================================================ IFL 2018 30th Symposium on Implementation and Application of Functional Languages University of Massachusetts Lowell, MA, USA September 5th-7th, 2018 http://iflconference.org ================================================================================ ### 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 2018 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. Topics of interest to IFL include, but are not limited to: - language concepts - type systems, type checking, type inferencing - compilation techniques - staged compilation - run-time function specialization - run-time code generation - partial evaluation - (abstract) interpretation - metaprogramming - generic programming - automatic program generation - array processing - concurrent/parallel programming - concurrent/parallel program execution - embedded systems - web applications - (embedded) domain specific languages - security - novel memory management techniques - run-time profiling performance measurements - debugging and tracing - virtual/abstract machine architectures - validation, verification of functional programs - tools and programming techniques - (industrial) applications ### Submissions and peer-review Differently from previous editions of IFL, IFL 2018 solicits two kinds of submissions: * Regular papers (12 pages including references) * Draft papers for presentations ('weak' limit between 8 and 15 pages) Regular papers will undergo a rigorous review by the program committee, and will be evaluated according to their correctness, novelty, originality, relevance, significance, and clarity. A set of regular papers will be conditionally accepted for publication. Authors of conditionally accepted papers will be provided with committee reviews along with a set of mandatory revisions. Regular papers not accepted for publication will be considered as draft papers, at the request of the author. Draft papers will be screened to make sure that they are within the scope of IFL, and will be accepted for presentation or rejected accordingly. Prior to the symposium: Authors of conditionally accepted papers and accepted presentations will submit a pre-proceedings version of their work that will appear in the draft proceedings distributed at the symposium. The draft proceedings does not constitute a formal publication. We require that at least one of the authors present the work at IFL 2018. After the symposium: Authors of conditionally accepted papers will submit a revised versions of their paper for the formal post-proceedings. The program committee will assess whether the mandatory revisions have been adequately addressed by the authors and thereby determines the final accept/reject status of the paper. Our interest is to ultimately accept all conditionally accepted papers. If you are an author of a conditionally accepted paper, please make sure that you address all the concerns of the reviewers. Authors of accepted presentations 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 post-proceedings. The program committee will evaluate these submissions according to their correctness, novelty, originality, relevance, significance, and clarity, and will thereby determine whether the paper is accepted or rejected. ### Publication The formal proceedings will appear in the International Conference Proceedings Series of the ACM Digital Library. 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 ### Important dates Submission of regular papers: May 25, 2018 Submission of draft papers: July 17, 2018 Regular and draft papers notification: July 20, 2018 Deadline for early registration: August 8, 2018 Submission of pre-proceedings version: August 29, 2018 IFL Symposium: September 5-7, 2018 Submission of papers for post-proceedings: November 7, 2018 Notification of acceptance: December 22, 2018 Camera-ready version: February 10, 2019 ### Submission details All contributions must be written in English. Papers must use the ACM two columns conference format, which can be found at: http://www.acm.org/publications/proceedings-template Authors submit through EasyChair: https://easychair.org/conferences/?conf=ifl2018 ### Peter Landin Prize The Peter Landin Prize is awarded to the best paper presented at the symposium every year. The honored article is selected by the program committee based on the submissions received for the formal review process. The prize carries a cash award equivalent to 150 Euros. ### Organization and Program committee Chairs: Jay McCarthy & Matteo Cimini, University of Massachusetts Lowell, USA Program Committee: * Arthur Chargu√©raud, Inria, FR * Ben Delaware, Purdue University, USA * Christos Dimoulas, Northwestern University, USA * David Darais, University of Vermont, USA * Dominic Orchard, University of Kent, UK * Ekaterina Komendantskaya, Heriot-Watt University, UK * Garrett Morris, University of Kansas, USA * Heather Miller, EPFL & Northeastern University, CH & USA * Jeremy Yallop, University of Cambridge, UK * Keiko Nakata, SAP Innovation Center Potsdam, DE * Laura Castro, University of A Coru√±a, ESP * Magnus Myreen, Chalmers University of Technology, SWE * Natalia Chechina, Bournemouth University, UK * Peter Achten, Radboud Universiteit Nijmegen, NL * Peter-Michael Osera, Grinnell College, USA * Richard Eisenberg, Bryn Mawr College, USA * Trevor McDonell, University of New South Wales, AUS * Yukiyoshi Kameyama, University of Tsukuba, JAP ### Venue The 30th IFL will take place at the UMass Lowell Inn & Conference Center in Lowell (MA), in association with the University of Massachusetts Lowell.

thread-cells?
by Dimitris Vyzovitis 12 Mar '18

12 Mar '18

Marc, Could we add thread-cells? They can be easily implemented with a per-thread hash-table, that only gets initialized if accessed. They are incredibly useful for per thread caches, and probably a lot of other things. For instance, I have this common pattern that i see a lot: (def errptr-cache (make-hash-table-eq weak-keys: #t)) (def errptr-cache-mutex (make-mutex)) (def (get-errptr) (with-lock errptr-cache-mutex (lambda () (cond ((hash-get errptr-cache (current-thread)) => (lambda (errptr) (errptr_clear errptr) errptr)) (else (let (errptr (check-ptr get-errptr (make_errptr))) (hash-put! errptr-cache (current-thread) errptr) errptr)))))) and I would like to eliminate both the lock and the weak table. I can add it and make a pr, but I wanted to consult with you first. -- vyzo

Final Call for Papers: PACMPL issue ICFP 2018
by Lindsey Kuper 08 Mar '18

08 Mar '18

PACMPL Volume 2, Issue ICFP 2018 Call for Papers accepted papers to be invited for presentation at The 23rd ACM SIGPLAN International Conference on Functional Programming St. Louis, Missouri, USA http://icfp18.sigplan.org/ ### Important dates Submissions due: 16 March 2018 (Friday) Anywhere on Earth https://icfp18.hotcrp.com Author response: 2 May (Wednesday) - 4 May (Friday) 14:00 UTC Notification: 18 May (Friday) Final copy due: 22 June (Friday) Conference: 24 September (Monday) - 26 September (Wednesday) ### About PACMPL Proceedings of the ACM on Programming Languages (PACMPL <https://pacmpl.acm.org/>) is a Gold Open Access journal publishing research on all aspects of programming languages, from design to implementation and from mathematical formalisms to empirical studies. Each issue of the journal is devoted to a particular subject area within programming languages and will be announced through publicized Calls for Papers, like this one. ### Scope [PACMPL](https://pacmpl.acm.org/) issue ICFP 2018 seeks original papers on the art and science of functional programming. Submissions are invited on all topics from principles to practice, from foundations to features, and from abstraction to application. The scope includes all languages that encourage functional programming, including both purely applicative and imperative languages, as well as languages with objects, concurrency, or parallelism. Topics of interest include (but are not limited to): * *Language Design*: concurrency, parallelism, and distribution; modules; components and composition; metaprogramming; type systems; interoperability; domain-specific languages; and relations to imperative, object-oriented, or logic programming. * *Implementation*: abstract machines; virtual machines; interpretation; compilation; compile-time and run-time optimization; garbage collection and memory management; multi-threading; exploiting parallel hardware; interfaces to foreign functions, services, components, or low-level machine resources. * *Software-Development Techniques*: algorithms and data structures; design patterns; specification; verification; validation; proof assistants; debugging; testing; tracing; profiling. * *Foundations*: formal semantics; lambda calculus; rewriting; type theory; monads; continuations; control; state; effects; program verification; dependent types. * *Analysis and Transformation*: control-flow; data-flow; abstract interpretation; partial evaluation; program calculation. * *Applications*: symbolic computing; formal-methods tools; artificial intelligence; systems programming; distributed-systems and web programming; hardware design; databases; XML processing; scientific and numerical computing; graphical user interfaces; multimedia and 3D graphics programming; scripting; system administration; security. * *Education*: teaching introductory programming; parallel programming; mathematical proof; algebra. Submissions will be evaluated according to their relevance, correctness, significance, originality, and clarity. Each submission should explain its contributions in both general and technical terms, clearly identifying what has been accomplished, explaining why it is significant, and comparing it with previous work. The technical content should be accessible to a broad audience. PACMPL issue ICFP 2018 also welcomes submissions in two separate categories — Functional Pearls and Experience Reports — that must be marked as such at the time of submission and that need not report original research results. Detailed guidelines on both categories are given at the end of this call. Please contact the principal editor if you have questions or are concerned about the appropriateness of a topic. ### Preparation of submissions **Deadline**: The deadline for submissions is Friday, March 16, 2018, Anywhere on Earth (<https://en.wikipedia.org/wiki/Anywhere_on_Earth>). This deadline will be strictly enforced. **Formatting**: Submissions must be in PDF format, printable in black and white on US Letter sized paper, and interpretable by common PDF tools. All submissions must adhere to the "ACM Small" template that is available (in both LaTeX and Word formats) from <https://www.acm.org/publications/authors/submissions>. For authors using LaTeX, a lighter-weight package, including only the essential files, is available from <http://sigplan.org/Resources/Author/#acmart-format>. There is a limit of 27 pages for a full paper or 14 pages for an Experience Report; in either case, the bibliography will not be counted against these limits. These page limits have been chosen to allow essentially the same amount of content with the new single-column format as was possible with the two-column format used in past ICFP conferences. Submissions that exceed the page limits or, for other reasons, do not meet the requirements for formatting, will be summarily rejected. See also PACMPL's Information and Guidelines for Authors at <https://pacmpl.acm.org/authors.cfm>. **Submission**: Submissions will be accepted at <https://icfp18.hotcrp.com/> Improved versions of a paper may be submitted at any point before the submission deadline using the same web interface. **Author Response Period**: Authors will have a 72-hour period, starting at 14:00 UTC on Wednesday, May 2, 2018, to read reviews and respond to them. **Supplementary Materials**: Authors have the option to attach supplementary material to a submission, on the understanding that reviewers may choose not to look at it. The material should be uploaded at submission time, as a single pdf or a tarball, not via a URL. This supplementary material may or may not be anonymized; if not anonymized, it will only be revealed to reviewers after they have submitted their review of the paper and learned the identity of the author(s). **Authorship Policies**: All submissions are expected to comply with the ACM Policies for Authorship that are detailed at <https://www.acm.org/publications/authors/information-for-authors>. **Republication Policies**: Each submission must adhere to SIGPLAN's republication policy, as explained on the web at <http://www.sigplan.org/Resources/Policies/Republication>. **Resubmitted Papers**: Authors who submit a revised version of a paper that has previously been rejected by another conference have the option to attach an annotated copy of the reviews of their previous submission(s), explaining how they have addressed these previous reviews in the present submission. If a reviewer identifies him/herself as a reviewer of this previous submission and wishes to see how his/her comments have been addressed, the principal editor will communicate to this reviewer the annotated copy of his/her previous review. Otherwise, no reviewer will read the annotated copies of the previous reviews. ### Review Process This section outlines the two-stage process with lightweight double-blind reviewing that will be used to select papers for PACMPL issue ICFP 2018. We anticipate that there will be a need to clarify and expand on this process, and we will maintain a list of frequently asked questions and answers on the conference website to address common concerns. **PACMPL issue ICFP 2018 will employ a two-stage review process.** The first stage in the review process will assess submitted papers using the criteria stated above and will allow for feedback and input on initial reviews through the author response period mentioned previously. At the review meeting, a set of papers will be conditionally accepted and all other papers will be rejected. Authors will be notified of these decisions on May 18, 2018. Authors of conditionally accepted papers will be provided with committee reviews (just as in previous conferences) along with a set of mandatory revisions. After five weeks (June 22, 2018), the authors will provide a second submission. The second and final reviewing phase assesses whether the mandatory revisions have been adequately addressed by the authors and thereby determines the final accept/reject status of the paper. The intent and expectation is that the mandatory revisions can be addressed within five weeks and hence that conditionally accepted papers will in general be accepted in the second phase. The second submission should clearly identify how the mandatory revisions were addressed. To that end, the second submission must be accompanied by a cover letter mapping each mandatory revision request to specific parts of the paper. The cover letter will facilitate a quick second review, allowing for confirmation of final acceptance within two weeks. Conversely, the absence of a cover letter will be grounds for the paper’s rejection. **PACMPL issue ICFP 2018 will employ a lightweight double-blind reviewing process.** To facilitate this, submitted papers must adhere to two rules: 1. **author names and institutions must be omitted**, and 2. **references to authors' own related work should be in the third person** (e.g., not "We build on our previous work ..." but rather "We build on the work of ..."). The purpose of this process is to help the reviewers come to an initial judgement about the paper without bias, not to make it impossible for them to discover the authors if they were to try. Nothing should be done in the name of anonymity that weakens the submission or makes the job of reviewing the paper more difficult (e.g., important background references should not be omitted or anonymized). In addition, authors should feel free to disseminate their ideas or draft versions of their paper as they normally would. For instance, authors may post drafts of their papers on the web or give talks on their research ideas. ### Information for Authors of Accepted Papers * As a condition of acceptance, final versions of all papers must adhere to the new ACM Small format. The page limits for final versions of papers will be increased to ensure that authors have space to respond to reviewer comments and mandatory revisions. * Authors of accepted submissions will be required to agree to one of the three ACM licensing options: open access on payment of a fee (**recommended**, and SIGPLAN can cover the cost as described next); copyright transfer to ACM; or retaining copyright but granting ACM exclusive publication rights. Further information about ACM author rights is available from <http://authors.acm.org>. * PACMPL is a Gold Open Access journal. It will be archived in ACM’s Digital Library, but no membership or fee is required for access. Gold Open Access has been made possible by generous funding through ACM SIGPLAN, which will cover all open access costs in the event authors cannot. Authors who can cover the costs may do so by paying an Article Processing Charge (APC). PACMPL, SIGPLAN, and ACM Headquarters are committed to exploring routes to making Gold Open Access publication both affordable and sustainable. * ACM offers authors a range of copyright options, one of which is Creative Commons CC-BY publication; this is the option recommended by the PACMPL editorial board. A reasoned argument in favour of this option can be found in the article [Why CC-BY?](https://oaspa.org/why-cc-by/) published by OASPA, the Open Access Scholarly Publishers Association. * We intend that the papers will be freely available for download from the ACM Digital Library in perpetuity via the OpenTOC mechanism. * ACM Author-Izer is a unique service that enables ACM authors to generate and post links on either their home page or institutional repository for visitors to download the definitive version of their articles from the ACM Digital Library at no charge. Downloads through Author-Izer links are captured in official ACM statistics, improving the accuracy of usage and impact measurements. Consistently linking to the definitive version of an ACM article should reduce user confusion over article versioning. After an article has been published and assigned to the appropriate ACM Author Profile pages, authors should visit <http://www.acm.org/publications/acm-author-izer-service> to learn how to create links for free downloads from the ACM DL. * At least one author of each accepted submissions will be expected to attend and present their paper at the conference. The schedule for presentations will be determined and shared with authors after the full program has been selected. Presentations will be videotaped and released online if the presenter consents. * The official publication date is the date the papers are made available in the ACM Digital Library. This date may be up to *two weeks prior* to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work. ### Artifact Evaluation Authors of papers that are conditionally accepted in the first phase of the review process will be encouraged (but not required) to submit supporting materials for Artifact Evaluation. These items will then be reviewed by an Artifact Evaluation Committee, separate from the paper Review Committee, whose task is to assess how the artifacts support the work described in the associated paper. Papers that go through the Artifact Evaluation process successfully will receive a seal of approval printed on the papers themselves. Authors of accepted papers will be encouraged to make the supporting materials publicly available upon publication of the papers, for example, by including them as "source materials" in the ACM Digital Library. An additional seal will mark papers whose artifacts are made available, as outlined in the ACM guidelines for artifact badging. Participation in Artifact Evaluation is voluntary and will not influence the final decision regarding paper acceptance. Further information about the motivations and expectations for Artifact Evaluation can be found at <https://icfp18.sigplan.org/track/icfp-2018-Artifacts>. ### Special categories of papers In addition to research papers, PACMPL issue ICFP solicits two kinds of papers that do not require original research contributions: Functional Pearls, which are full papers, and Experience Reports, which are limited to half the length of a full paper. Authors submitting such papers should consider the following guidelines. #### Functional Pearls A Functional Pearl is an elegant essay about something related to functional programming. Examples include, but are not limited to: * a new and thought-provoking way of looking at an old idea * an instructive example of program calculation or proof * a nifty presentation of an old or new data structure * an interesting application of functional programming techniques * a novel use or exposition of functional programming in the classroom While pearls often demonstrate an idea through the development of a short program, there is no requirement or expectation that they do so. Thus, they encompass the notions of theoretical and educational pearls. Functional Pearls are valued as highly and judged as rigorously as ordinary papers, but using somewhat different criteria. In particular, a pearl is not required to report original research, but, it should be concise, instructive, and entertaining. A pearl is likely to be rejected if its readers get bored, if the material gets too complicated, if too much specialized knowledge is needed, or if the writing is inelegant. The key to writing a good pearl is polishing. A submission that is intended to be treated as a pearl must be marked as such on the submission web page, and should contain the words "Functional Pearl" somewhere in its title or subtitle. These steps will alert reviewers to use the appropriate evaluation criteria. Pearls will be combined with ordinary papers, however, for the purpose of computing the conference's acceptance rate. #### Experience Reports The purpose of an Experience Report is to help create a body of published, refereed, citable evidence that functional programming really works — or to describe what obstacles prevent it from working. Possible topics for an Experience Report include, but are not limited to: * insights gained from real-world projects using functional programming * comparison of functional programming with conventional programming in the context of an industrial project or a university curriculum * project-management, business, or legal issues encountered when using functional programming in a real-world project * curricular issues encountered when using functional programming in education * real-world constraints that created special challenges for an implementation of a functional language or for functional programming in general An Experience Report is distinguished from a normal PACMPL issue ICFP paper by its title, by its length, and by the criteria used to evaluate it. * Both in the papers and in any citations, the title of each accepted Experience Report must begin with the words "Experience Report" followed by a colon. The acceptance rate for Experience Reports will be computed and reported separately from the rate for ordinary papers. * Experience Report submissions can be at most 12 pages long, excluding bibliography. * Each accepted Experience Report will be presented at the conference, but depending on the number of Experience Reports and regular papers accepted, authors of Experience reports may be asked to give shorter talks. * Because the purpose of Experience Reports is to enable our community to accumulate a body of evidence about the efficacy of functional programming, an acceptable Experience Report need not add to the body of knowledge of the functional-programming community by presenting novel results or conclusions. It is sufficient if the Report states a clear thesis and provides supporting evidence. The thesis must be relevant to ICFP, but it need not be novel. The review committee will accept or reject Experience Reports based on whether they judge the evidence to be convincing. Anecdotal evidence will be acceptable provided it is well argued and the author explains what efforts were made to gather as much evidence as possible. Typically, more convincing evidence is obtained from papers which show how functional programming was used than from papers which only say that functional programming was used. The most convincing evidence often includes comparisons of situations before and after the introduction or discontinuation of functional programming. Evidence drawn from a single person's experience may be sufficient, but more weight will be given to evidence drawn from the experience of groups of people. An Experience Report should be short and to the point: it should make a claim about how well functional programming worked on a particular project and why, and produce evidence to substantiate this claim. If functional programming worked in this case in the same ways it has worked for others, the paper need only summarize the results — the main part of the paper should discuss how well it worked and in what context. Most readers will not want to know all the details of the project and its implementation, but the paper should characterize the project and its context well enough so that readers can judge to what degree this experience is relevant to their own projects. The paper should take care to highlight any unusual aspects of the project. Specifics about the project are more valuable than generalities about functional programming; for example, it is more valuable to say that the team delivered its software a month ahead of schedule than it is to say that functional programming made the team more productive. If the paper not only describes experience but also presents new technical results, or if the experience refutes cherished beliefs of the functional-programming community, it may be better off submitted it as a full paper, which will be judged by the usual criteria of novelty, originality, and relevance. The principal editor will be happy to advise on any concerns about which category to submit to. ### ICFP Organizers General Chair: Robby Findler (Northwestern University, USA) Artifact Evaluation Co-Chairs: Simon Marlow (Facebook, UK) Ryan R.

1st call for papers: Trends in Functional Programming, 11-13 june 2018, Chalmers Campus Johanneberg, Gothenburg
by Peter Achten 07 Mar '18

07 Mar '18

----------------------------- C A L L F O R P A P E R S ----------------------------- ======== TFP 2018 =========== 19th Symposium on Trends in Functional Programming 11-13 June, 2018 Chalmers Campus Johanneberg, Gothenburg http://www.cse.chalmers.se/~myreen/tfp2018/index.html The symposium on Trends in Functional Programming (TFP) is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area. It aspires to be a lively environment for presenting the latest research results, and other contributions (see below at scope). Please be aware that TFP uses two distinct rounds of submissions (see below at submission details). TFP 2018 will be the main event of a pair of functional programming events. TFP 2018 will be accompanied by the International Workshop on Trends in Functional Programming in Education (TFPIE), which will take place on June 14. == SCOPE == The symposium recognizes that new trends may arise through various routes. As part of the Symposium's focus on trends we therefore identify the following five article categories. High-quality articles are solicited in any of these categories: Research Articles: Leading-edge, previously unpublished research work Position Articles: On what new trends should or should not be Project Articles: Descriptions of recently started new projects Evaluation Articles: What lessons can be drawn from a finished project Overview Articles: Summarizing work with respect to a trendy subject. Articles must be original and not simultaneously submitted for publication to any other forum. They may consider any aspect of functional programming: theoretical, implementation-oriented, or experience-oriented. Applications of functional programming techniques to other languages are also within the scope of the symposium. Topics suitable for the symposium include, but are not limited to: Functional programming and multicore/manycore computing Functional programming in the cloud High performance functional computing Extra-functional (behavioural) properties of functional programs Dependently typed functional programming Validation and verification of functional programs Debugging and profiling for functional languages Functional programming in different application areas: security, mobility, telecommunications applications, embedded systems, global computing, grids, etc. Interoperability with imperative programming languages Novel memory management techniques Program analysis and transformation techniques Empirical performance studies Abstract/virtual machines and compilers for functional languages (Embedded) domain specific languages New implementation strategies Any new emerging trend in the functional programming area If you are in doubt on whether your article is within the scope of TFP, please contact the TFP 2018 program chairs, Michał Pałka and Magnus Myreen. == Best Paper Awards == To reward excellent contributions, TFP awards a prize for the best paper accepted for the formal proceedings. TFP traditionally pays special attention to research students, acknowledging that students are almost by definition part of new subject trends. A student paper is one for which the authors state that the paper is mainly the work of students, the students are listed as first authors, and a student would present the paper. A prize for the best student paper is awarded each year. In both cases, it is the PC of TFP that awards the prize. In case the best paper happens to be a student paper, that paper will then receive both prizes. == Paper Submissions == We use EasyChair for the refereeing process. The link to the submission page is: https://easychair.org/conferences/?conf=tfp2018 Authors of papers have the choice of having their contributions formally reviewed either before or after the Symposium. == Pre-symposium formal review == Papers to be formally reviewed before the symposium should be submitted before an early deadline and receive their reviews and notification of acceptance for both presentation and publication before the symposium. A paper that has been rejected in this process may still be accepted for presentation at the symposium, but will not be considered for the post-symposium formal review. == Post-symposium formal review == Draft papers will receive minimal reviews and notification of acceptance for presentation at the symposium. Authors of draft papers will be invited to submit revised papers based on the feedback receive at the symposium. A post-symposium refereeing process will then select a subset of these articles for formal publication. == Paper categories == Draft papers and papers submitted for formal review are submitted as extended abstracts (4 to 10 pages in length) or full papers (20 pages). The submission must clearly indicate which category it belongs to: research, position, project, evaluation, or overview paper. It should also indicate which authors are research students, and whether the main author(s) are students. A draft paper for which all authors are students will receive additional feedback by one of the PC members shortly after the symposium has taken place. == Format == Papers must be written in English, and written using the LNCS style. For more information about formatting please consult the Springer LNCS web site. == Important Dates == Submission (pre-symposium review): March 26, 2018 Submission (draft, post-symposium review): April 26, 2018 Notification (pre- and post-symposium review): May 3, 2018 Registration: June 3, 2018 TFP Symposium: June 11-13, 2018 TFPIE Workshop: June 14, 2018 Student papers feedback: June 21, 2018 Submission (post-symposium review): August 14, 2018 Notification (post-symposium review): September 20, 2018 Camera-ready paper (pre- and post-symposium review): November 30, 2018 == Program Committee == Program Co-chairs Michał Pałka, Chalmers University of Technology (SE) Magnus Myreen, Chalmers University of Technology (SE) Program Committee Soichiro Hidaka, Hosei University (JP) Meng Wang, University of Bristol (UK) Sam Tobin-Hochstadt, Indiana University Bloomington (US) Tiark Rompf, Purdue University (US) Patricia Johann, Appalachian State University (US) Neil Sculthorpe, Nottingham Trent University (UK) Andres Löh, Well-Typed LLP (UK) Tarmo Uustalu, Tallinn University of Technology (EE) Cosmin E.

full program optimization
by Dimitris Vyzovitis 05 Mar '18

05 Mar '18

Hi Marc, Does gsc perform any full program optimization and cross module inlining when compiling executables? I am particularly interested in the case of linking multiple scheme modules together to compile executables. The Gerbil compiler uses this mode for compiling static executables, which was done with full program optimization in mind. At a very basic level, it allows global prelude declarations like `(not safe)` to be applied to the whole program, but it could do much more. It doesn't have to be too complicated: - the partial evaluator should look across module boundaries - small procedures should be inlined across module boundaries - (block) declarations should be taken into account across modules, so that mutability information can be propagated. Tthis would allow the compiler to elide procedure call checks for procedures defined in another module when the binding is not mutated. -- vyzo

First Call for Papers: 11th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2018)
by Andrei Chis 16 Fév '18

16 Fév '18

------------------------------------------------------------------------ Call for Papers: 11th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2018) co-located with SPLASH 2018 November 5-6, 2018 Boston, Massachusetts, United States https://conf.researchr.org/track/sle-2018/papers ------------------------------------------------------------------------ We are pleased to invite you to submit papers to the 11th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2018), held in conjunction with SPLASH 2018 at Boston, Massachusetts on November 5-6, 2018. --------------------------- Scope --------------------------- With the ubiquity of computers, software has become the dominating intellectual asset of our time. In turn, this software depends on software languages, namely the languages it is written in, the languages used to describe its environment, and the languages driving its development process. Given that everything depends on software and that software depends on software languages, it seems fair to say that for many years to come, everything will depend on software languages. Software language engineering (SLE) is the discipline of engineering languages and their tools required for the creation of software. It abstracts from the differences between programming languages, modelling languages, and other software languages, and emphasizes the engineering facet of the creation of such languages, that is, the establishment of the scientific methods and practices that enable the best results. While SLE is certainly driven by its metacircular character (software languages are engineered using software languages), SLE is not self-satisfying: its scope extends to the engineering of languages for all and everything. Like its predecessors, the 11th edition of the SLE conference, SLE 2018, will bring together researchers from different areas united by their common interest in the creation, capture, and tooling of software languages. It overlaps with traditional conferences on the design and implementation of programming languages, model-driven engineering, and compiler construction, and emphasizes the fusion of their communities. To foster the latter, SLE traditionally fills a two-day program with a single track, with the only temporal overlap occurring between co-located events. --------------------------- Topics of Interest --------------------------- SLE 2018 solicits high-quality contributions in areas ranging from theoretical and conceptual contributions, to tools, techniques, and frameworks in the domain of software language engineering. Topics relevant to SLE cover generic aspects of software languages development rather than aspects of engineering a specific language. In particular, SLE is interested in contributions from the following areas: * Software Language Design and Implementation - Approaches to and methods for language design - Static semantics (e.g., design rules, well-formedness constraints) - Techniques for specifying behavioral / executable semantics - Generative approaches (incl. code synthesis, compilation) - Meta-languages, meta-tools, language workbenches * Software Language Validation - Verification and formal methods for languages - Testing techniques for languages - Simulation techniques for languages * Software Language Integration and Composition - Coordination of heterogeneous languages and tools - Mappings between languages (incl. transformation languages) - Traceability between languages - Deployment of languages to different platforms * Software Language Maintenance - Software language reuse - Language evolution - Language families and variability * Domain-specific approaches for any aspects of SLE (design, implementation, validation, maintenance) * Empirical evaluation and experience reports of language engineering tools - User studies evaluating usability - Performance benchmarks - Industrial applications --------------------------- Important Dates --------------------------- All dates are Anywhere on Earth. * Fri 29 June 2018 - Abstract Submission * Fri 6 July 2018 - Paper Submission * Fri 24 August 2018 - Author Notification * Fri 31 August 2018 - Artifact Submission * Fri 5 October 2018 - Camera Ready Deadline * Wed 10 October 2018 - Artifact Notification * Fri 12 October 2018 - Deadline for Artifact-Related Paper Updates * Sun 4 Nov 2018 - SLE Workshops * Mon 5 Nov - Tue 6 Nov 2018 - SLE Conference --------------------------- Types of Submissions --------------------------- * Research papers These should report a substantial research contribution to SLE or successful application of SLE techniques or both. Full paper submissions must not exceed 12 pages excluding bibliography. * Tool papers Because of SLE’s interest in tools, we seek papers that present software tools related to the field of SLE. Selection criteria include originality of the tool, its innovative aspects, and relevance to SLE. Any of the SLE topics of interest are appropriate areas for tool demonstrations. Submissions must provide a tool description of 4 pages excluding bibliography, and a demonstration outline including screenshots of up to 6 pages. Tool demonstrations must have the keywords “Tool Demo” or “Tool Demonstration” in the title. The 4-page tool description will, if the demonstration is accepted, be published in the proceedings. The 6-page demonstration outline will be used by the program committee only for evaluating the submission. * New ideas / vision papers New ideas papers should describe new, non-conventional SLE research approaches that depart from standard practice. They are intended to describe well-defined research ideas that are at an early stage of investigation. Vision papers are intended to present new unifying theories about existing SLE research that can lead to the development of new technologies or approaches. New ideas / vision papers must not exceed 4 pages excluding bibliography. Workshops: Workshops will be organized by SPLASH. Please inform us and contact the SPLASH organizers if you would like to organize a workshop of interest to the SLE audience. Information on how to submit workshops can be found at the SPLASH 2018 Website: https://conf.researchr.org/track/splash-2018/splash-2018-Workshops. --------------------------- Artifact Evaluation --------------------------- For the third year SLE will use an evaluation process for assessing the quality of the artifacts on which papers are based to foster the culture of experimental reproducibility. Authors of accepted papers are invited to submit artifacts. More information will be announced on the Website. --------------------------- Submission --------------------------- Submissions have to use the ACM SIGPLAN Conference Format "acmart" ( http://sigplan.org/Resources/Author/#acmart-format) please make sure that you always use the latest ACM SIGPLAN acmart LaTeX template ( https://www.acm.org/binaries/content/assets/publications/consolidated-tex-t…) and that the document class definition is \documentclass[sigplan,screen]{acmart}. Do not make any changes to this format! Using the Word template is strongly discouraged. Ensure that your submission is legible when printed on a black and white printer. In particular, please check that colors remain distinct and font sizes in figures and tables are legible. SLE follows a single-blind review process. Thus, you do not have to blind your submission. All submissions must be in PDF format. Concurrent Submissions: 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 ( http://www.acm.org/publications/policies/plagiarism_policy) Submissions that violate these policies will be desk-rejected. Submission Site: Submissions will be accepted at https://sle18.hotcrp.com/. --------------------------- Reviewing Process --------------------------- All submitted papers will be reviewed by at least three members of the program committee. Research papers and tool papers will be evaluated concerning novelty, correctness, significance, readability, and alignment with the conference call. New ideas / vision papers will be evaluated primarily concerning novelty, significance, readability, and alignment with the conference call. For fairness reasons, all submitted papers must conform to the above instructions. Submissions that violate these instructions may be rejected without review, at the discretion of the PC chairs. --------------------------- Awards --------------------------- * Distinguished paper: Award for most notable paper, as determined by the PC chairs based on the recommendations of the programme committee. * Distinguished reviewer: Award for distinguished reviewer, as determined by the PC chairs. * Distinguished artifact: Award for the artifact most significantly exceeding expectations, as determined by the AEC chairs based on the recommendations of the artifact evaluation committee. --------------------------- Publication --------------------------- All accepted papers will be published in the ACM Digital Library. AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work. --------------------------- Program Committee --------------------------- Andrew Black, Portland State University, USA Erwan Bousse, TU Wien, Austria Marco Brambilla, Politecnico di Milano, Italy Ruth Breu, University of Innsbruck, Austria Walter Cazzola, University of Milan, Italy Marsha Chechik, University of Toronto, Canada Tony Clark, Sheffield Hallam University, UK Juan de Lara, Universidad Autonoma de Madrid, Spain Thomas Degueule, CWI Amsterdam, Netherlands Juergen Dingel, Queen's University, Canada Tom Dinkelaker, Ericsson, Germany Sebastian Erdweg, Delft University of Technology, Netherlands Bernd Fischer, Stellenbosch University, South Africa Esther Guerra, Autonomous University of Madrid, Spain Daco Harkes, Delft University of Technology, Netherlands Robert Hirschfeld, University of Potsdam, Germany Michael Homer, Victoria University of Wellington, New Zealand Dimitris Kolovos, University of York, UK Ralf Lämmel, University of Koblenz-Landau, Germany Marjan Mernik, University of Maribor, Slovenia Gunter Mussbacher, McGill University, Canada James Noble, Victoria University of Wellington, New Zealand Bruno Oliveira, University of Hong Kong, China Christoph Reichenbach, Lund University, Sweden Jan Oliver Ringert, University of Leicester, UK Bernhard Rumpe, RWTH Aachen University, Germany Anthony Sloane, Macquarie University, Australia Emma Söderberg, Google, Denmark Mark van den Brand, TU Eindhoven, Netherlands Tijs van der Storm, CWI Amsterdam, Netherlands Eelco Visser, Delft University of Technology, Netherlands Eric Walkingshaw, Oregon State University, USA Andreas Wortmann, RWTH Aachen University, Germany Vadim Zaytsev, Rain Code, Belgium --------------------------- Contact --------------------------- For additional information, clarification, or answers to questions, please contact the organizers by email: sle2018(a)googlegroups.com.
