15 Aoû '19

------------------------------------------------------------------------- First call for papers 21st Symposium on Trends in Functional Programming tfp2020.org ------------------------------------------------------------------------- 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. * TFP is moving to new winter dates, to provide an FP forum in between the annual ICFP events. * TFP offers a supportive reviewing process designed to help less experienced authors succeed, with two rounds of review, both before and after the symposium itself. Authors have an opportunity to address reviewers' concerns before final decisions on publication in the proceedings. * TFP offers two "best paper" awards, the John McCarthy award for best paper, and the David Turner award for best student paper. * This year we are particularly excited to co-locate with Lambda Days in beautiful Krakow. Lambda Days is a vibrant developer conference with hundreds of attendees and a lively programme of talks on functional programming in practice. TFP will be held in the same venue, and participants will be able to session-hop between the two events. Important Dates --------------- Submission deadline for pre-symposium review: 15th November, 2019 Submission deadline for draft papers: 10th January, 2020 Symposium dates: 13-14th February, 2020 Visit tfp2020.org for more information.

Scheme Coding Competition
by Amirouche Boubekki 07 Aoû '19

07 Aoû '19

I am organizing a Scheme coding competition where you have to build a static blog generator with a mystery feature (that will be revealed little by little in the next few months). We already have sourcehut.org as a sponsor and I am actively looking for other sponsors to reward the participants (goodies, cloud credits, books...). More information after the jump: https://git.sr.ht/~schemers/competition-2019-static-blog-generator#schemers… Ultimately the goal is to contribute a scheme presence at https://www.staticgen.com/ Follow @schemers@mastodon.technology <https://mastodon.technology/@schemers> for more regular updates. Good read and good luck!

Final call for draft papers for IFL 2019 (Implementation and Application of Functional Languages)
by Jurriaan Hage 26 Jul '19

26 Jul '19

Hello, Please, find below the final call for draft papers for IFL 2019. 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 2019 31st Symposium on Implementation and Application of Functional Languages National University of Singapore September 25th-27th, 2019 http://2019.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 2019 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 ### Keynote Speaker * Olivier Danvy, Yale-NUS College ### Submissions and peer-review Differently from previous editions of IFL, IFL 2019 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 2019. 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: June 15, 2019 Submission of draft papers: August 1, 2019 Regular papers notification: August 1, 2019 Regular draft papers notification: August 7, 2019 Deadline for early registration: August 15, 2019 Submission of pre-proceedings version: September 15, 2019 IFL Symposium: September 25-27, 2019 Submission of papers for post-proceedings: November 30, 2019 Notification of acceptance: January 31, 2020 Camera-ready version: February 29, 2020 ### 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=ifl2019 ### 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: Jurrien Stutterheim (Standard Chartered Bank Singapore), Wei Ngan Chin (National University of Singapore) Program Committee: - Olaf Chitil, University of Kent - Clemens Grelck, University of Amsterdam - Daisuke Kimura, Toho University - Pieter Koopman, Radboud University - Tamás Kozsik, Eötvös Loránd University - Roman Leschinskiy, Facebook - Ben Lippmeier, The University of New South Wales - Marco T.

Demo of dynamic libraries?
by mikel evins 20 Jul '19

20 Jul '19

Is there a small example project somewhere that demonstrates building a Gambit program as a dynamic library (ideally on macOS), and then loading and initializing it from C code? I've looked but didn't notice this specific use-case in the distribution. Forgive me if I've overlooked something obvious. --me

Gambit at 30
by Marc Feeley 19 Jul '19

19 Jul '19

This year is the 30th anniversary of Gambit. To mark the occasion I am planning to organize a 1-2 day meeting this fall in Montreal if enough people can attend. The content remains to be determined but I can imagine some more-or-less formal presentations by me and attendants, brainstorming sessions and maybe some hacking on Gambit. To maximize attendance the meeting will be on a weekend, probably in September or October. So please let the list know if you are interested in attending, and if you have preferences for the date. Also please indicate if you are interested in giving a presentation (15-30 minutes or more if you have lots of material) or organize some other activity. Marc

How to monitor arbitrary file descriptors?
by Jörg F. Wittenberger 16 Jul '19

16 Jul '19

Hi, I'm trying to wait for IO on some file descriptor. The case at hand is not really relevant, it's a unix domain socket in this case. But the same issue would easily apply to other libraries too. So far I found the gamsock library as a start. But this ties up the processor in a loop attempting to receive, learn EWOULDBLOCK and retry. As I said, I'm not at all sold to the gamsock library or the API. I just want a thread to block on a raw file descriptor for IO. So maybe there is a way to create a port from a raw file descriptor? Or anything like that? How would it be done? Thank you so much. /Jörg

Compiling to Javascript
by hashavtech＠outlook.com 13 Jul '19

13 Jul '19

There are some messages in 2013 and 2016 that gave me a hint of what needs to be done in order to compile to js. But it seems that some things have changed (for example the gsc with -target js does not seem to produce a .js file, it gave me an .o1 file that contained Javascript). I was able to compile a working example once but the .js file contains the whole _gambit.js library and is 22 MB in size. That isn't really what I was hoping for. I've seen it mentioned that there was some work done on only including the necessary parts of the library, but I was unable to figure out how to do it (I'm new to Gambit although not to Lisp). I'd be glad for some help getting from a Scheme file to a working and reasonably-sized file. My goal is to include scheme-sourced parts in a web app, so there probably will be some interoperability issues, but at the moment I'm stuck at the compilation stage.

SMP build note
by Adam 05 Jul '19

05 Jul '19

Marc says build is ./configure --enable-multiple-threaded-vms --enable-smp make; make bootstrap; make bootclean; make and "the bootstrap step is needed because the Scheme code of the thread scheduler needs to be recompiled". Related gambit/include.h DEFINE:s are ___MAX_PROCESSORS, which is 64, and ___MULTIPLE_THREADED_VMS which is set. thread-send/receive currently crashes, and otherwise looks perfect.
