SRFI 14 and data structures in gambit/lib/gambit/char/char#.scm
by Bradley Lucier 23 Mai '23

23 Mai '23

Marc: I'd like to have an implementation of SRFI 14 (character sets) that works with the entire unicode character set rather than just the 256-character Latin1 subset I think one needs a data structure that allows compact encoding of relatively large (about $2^{21}$ elements) sets of positive integers that have lots of contiguous subsets. At any rate, I thought you may have solved this problem in gambit/lib/gambit/char/char#.scm, but for the life of me I can't figure out what you're doing there. Can your data sets for encoding Unicode properties be used for an efficient SRFI 14 implementation? Brad

A Lisp that runs on Wasm?
by Winston W 20 Mar '23

20 Mar '23

Hi Gambit List— I'm searching for a way to write Lisp and have it run on a web browser as WASM, i.e. avoiding JS. I was hoping Gambit Scheme might be the key, by compiling Lisp —> (Gambit compiler) —> C —> (Clang) —> wasm. But I'm encountering problems. My current issue is the 'gambit.h' file checks for lots of things including `setjmp` which doesn't exist in WASM. Below is my test situation. Does anybody think this endeavor of compiling Gambit -> wasm can work? Or are there any other ways to write Lisp and execute it as Wasm? --- ``` ;; fib.scm (define (square x) (expt x 2)) ``` ``` % gsc -c fib ``` produces a fib.c file. Then: ``` % clang --target=wasm32 -O1 -Wno-deprecated-declarations -Wno-unused -Wno-write-strings -Wdisabled-optimization -fwrapv -fno-strict-aliasing -fno-math-errno -fomit-frame-pointer -fPIC -fno-common -D___SINGLE_HOST -D___DONT_HAVE_MATH_H -D___DONT_HAVE_SETJMP_H -D___DONT_HAVE_SIGNAL_H -D___DONT_HAVE_WCHAR_H -I"/opt/homebrew/Cellar/gambit-scheme/4.9.3_2/v4.9.3/include" fib.c ``` Gives this error: ``` In file included from fib.c:36: /opt/homebrew/Cellar/gambit-scheme/4.9.3_2/v4.9.3/include/gambit.h:8012:5: error: unknown type name 'jmp_buf' jmp_buf buf; ^ 1 error generated. make: *** [fib.o] Error 1 ```

by Andrei Chis 06 Mar '23

06 Mar '23

------------------------------------------------------------------------ 16th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2023) October 22-27, 2023 Cascais, Lisbon, Portugal http://www.sleconf.org/2023/ Follow us on Twitter: https://twitter.com/sleconf ------------------------------------------------------------------------ We are pleased to invite you to submit papers to the 16th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2023), held in conjunction with SPLASH 2023. The conference will be hosted in Cascais, Lisbon, Portugal on October 22-27, 2023. --------------------------- Topics of Interest --------------------------- SLE covers software language engineering rather than engineering a specific software language. Topics of interest include, but are not limited to: * 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, language and software product lines * 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 * Synergies between Language Engineering and emerging/promising research areas - AI and ML language engineering (e.g., ML compiler testing, code classification) Quantum language engineering (e.g., language design for quantum machines) - Language engineering for physical systems (e.g., CPS, IoT, digital twins) - Socio-technical systems and language engineering (e.g., language evolution to adapt to social requirements) - Etc. --------------------------- Types of Submissions --------------------------- SLE accepts the following types of papers: * Research papers: These are “traditional” papers detailing research contributions to SLE. Papers may range from 6 to 12 pages in length and may optionally include 2 further pages of bibliography/appendices. Papers will be reviewed with an understanding that some results do not need 12 full pages and may be fully described in fewer pages. * New ideas/vision papers: These papers may describe new, unconventional software language engineering research positions or approaches that depart from standard practice. They can describe well-defined research ideas that are at an early stage of investigation. They could also provide new evidence to challenge common wisdom, present new unifying theories about existing SLE research that provides novel insight or that can lead to the development of new technologies or approaches, or apply SLE technology to radically new application areas. New ideas/vision papers must not exceed 5 pages and may optionally include 1 further page of bibliography/appendices. * SLE Body of Knowledge: The SLE Body of Knowledge (SLEBoK) is a community-wide effort to provide a unique and comprehensive description of the concepts, best practices, tools, and methods developed by the SLE community. In this respect, the SLE conference will accept surveys, essays, open challenges, empirical observations, and case study papers on the SLE topics. These can focus on, but are not limited to, methods, techniques, best practices, and teaching approaches. Papers in this category can have up to 20 pages, including bibliography/appendices. * Tool papers: These papers focus on the tooling aspects often forgotten or neglected in research papers. A good tool paper focuses on practical insights that will likely be useful to other implementers or users in the future. Any of the SLE topics of interest are appropriate areas for tool demonstrations. Submissions must not exceed 5 pages and may optionally include 1 further page of bibliography/appendices. They may optionally include an appendix with a demo outline/screenshots and/or a short video/screencast illustrating the tool. **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 on the SPLASH 2023 Website. --------------------------- Important Dates --------------------------- All dates are Anywhere on Earth. * 1st round submissions - Abstract submissions: March 31, 2023 - Paper submissions: April 7, 2023 - Notification: May 5, 2023 * 2nd round submissions - Abstract submissions: June 26, 2023 - Paper submissions: June 30, 2023 - Review notification: August 11, 2023 (starting of the rebuttal) - Author response period: August 18, 2023 (end of the rebuttal) - Notification: August 25, 2023 * Artifact submissions: August 30, 2023 * Artifact kick-the-tires Author response: September 15, 2023 * Artifact notification: September 29, 2023 * Conference: October 22-27, 2023 (co-located with SPLASH, precise dates to be announced) --------------------------- Format --------------------------- 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/consolida…, and that the document class definition is `\documentclass[sigplan,anonymous,review]{acmart}`.

CfP: Journal of Systems and Software - Special Issue on Software Language Engineering
by Andrei Chis 13 Jan '23

13 Jan '23

Dear Colleagues, We invite submissions for the Journal of Systems and Software Special Issue on «Software Language Engineering». This special issue is related to the 2022 edition of the Software Language Engineering Conference (https://2022.splashcon.org/home/sle-2022?) but **it is open to all authors.** Details follow. -------------------------------------------------------------------------------------- Journal of Systems and Software Software Language Engineering Special Issue Guest Editors ● Lola Burgueño, University of Malaga, Spain ● Walter Cazzola, Professor, Università degli Studi di Milano, Italy ● Dimitris Kolovos, Professor, University of York, United Kingdom Special issue information: 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, modeling 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 meta-circular 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. This special issue will represent a further step in identification, definition and tooling of software languages. Topics of interest related to the special issue, but are not limited to: ● 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, language and software product lines ○ 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 ● Synergies between Language Engineering and emerging/promising research areas ○ AI and ML language engineering (e.g., ML compiler testing, code classification) ○ Quantum language engineering (e.g., language design for quantum machines) ● Language engineering for physical systems (e.g., CPS, IoT, digital twins) ○ Socio-technical systems and language engineering (e.g., language evolution to adapt to social requirements) Manuscript submission information: Proposed Dates and Outcomes ● Submission: 15 February 2023 ● Notification to authors (first round): 15 April 2023 ● Submission of revised papers (second round): 15 June 2023 ● Notification to authors (second round): 15 August 2023 ● Submission after second review: 15 October 2023 ● Final acceptance: 15 November 2023 ● Date of publication: 15 December 2023 Submission Guidelines The call for this special issue is an open call. We invite innovative research with a sound scientific or technological basis and validation. We accept submissions of original and previously unpublished manuscripts and we especially encourage the submission of revised and extended papers from the 15th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2022). If a previous version of the manuscript has been published in a conference or journal, then authors must explicitly explain the novelty of this new submission and provide at least 30% new material. Surveys, literature reviews and mapping studies would not be considered as part of this special issue. All manuscripts and any supplementary material should be submitted through the Elsevier Editorial System at https://www.editorialmanager.com/jssoftware/default1.aspx. Follow the submission instructions given on this site. During the submission process, select the article type "VSI:SLE" from the "Choose Article Type" pull-down menu. All submissions must adhere to the general principles of the Journal of Systems and Software articles. Submissions have to be prepared according to the Guide for Authors, available on the journal website, and must follow the format specified in the JSS Guide for Authors https://www.elsevier.com/journals/journal-of-systems-and-software/0164-1212…. For more information about the special issue, please contact the guest editors.

[TFP 2023 Call For Participation] 24th International Symposium on Trends in Functional Programming
by Peter Achten 02 Jan '23

02 Jan '23

# TFP 2023 -- Call For Participation (trendsfp.github.io) ## Dates Registration: Friday 6th January, 2023 TFPIE Workshop: Thursday 12th January, 2023 TFP Symposium: Friday 13th - Sunday 15th January, 2023 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. This year, TFP will take place in-person at UMass Boston, Massachusetts in the United States. It is co-located with the Trends in Functional Programming in Education (TFPIE) workshop, which will take on the day before the main symposium. ## 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 2023 program chair, Stephen Chang. ## Best Paper Awards TFP awards two prizes for the best papers each year. First, to reward excellent contributions, TFP awards a prize for the best overall paper accepted for the post-conference formal proceedings. Second, a prize for the best student paper is awarded each year. 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. In both cases, it is the PC of TFP that awards the prize. In case the best paper happens to be a student paper, then that paper will receive both prizes. ## Instructions to Authors Papers must be submitted at: <https://easychair.org/conferences/?conf=tfp23> Authors of papers have the choice of having their contributions formally reviewed either before or after the Symposium. Further, pre-symposium submissions may either be full (earlier deadline) or draft papers (later deadline). ## Pre-symposium formal review Papers to be formally reviewed before the symposium should be submitted before the early deadline and will receive their reviews and notification of acceptance for both presentation and publication before the symposium. A paper that has been rejected for publication but accepted for presentation may be resubmitted 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. ## Program Committee Peter Achten, Radboud University Nijmegen, Netherlands Nada Amin, Harvard University, USA Ambrose Bonnaire-Sergeant, Untypable LLC, USA Laura M.

I intend to remove SRFI 179 support (use SRFI 231 instead)
by Bradley Lucier 30 Sep '22

30 Sep '22

I've added SRFI 231, Intervals and Generalized Arrays, to the Gambit source tree: https://srfi.schemers.org/srfi-231/ SRFI 231 is an updated and improved version of SRFI 179. There are a few incompatible changes between the two SRFIs, see https://srfi.schemers.org/srfi-231/srfi-231.html#Rationale As SRFI 231 improves SRFI 179 in almost every way, I intend to remove SRFI 179 support from the GitHub repository soon.

[TFP 2023 Call for Papers] 24th International Symposium on Trends in Functional Programming
by Peter Achten 19 Sep '22

19 Sep '22

# TFP 2023 -- Call for Papers (trendsfp.github.io) ## Important Dates Submission deadline: pre-symposium, full papers, Wednesday 23rd November, 2022 Submission deadline: pre-symposium, draft papers, Friday 16th December, 2022 Notification: pre-symposium submissions, Friday 23rd December, 2022 Registration: Friday 6th January, 2023 TFPIE Workshop: Thursday 12th January, 2023 TFP Symposium: Friday 13th - Sunday 15th January, 2023 Submission deadline: post-symposium review, Friday 17th February, 2023 Notification: post-symposium submissions, Friday 31st March, 2023 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. This year, TFP will take place in-person at UMass Boston, Massachusetts in the United States. It is co-located with the Trends in Functional Programming in Education (TFPIE) workshop, which will take on the day before the main symposium. Please be aware that TFP has several submission deadlines. The first, November 23, is for authors that wish to have their full paper reviewed prior to the symposium. Papers that are accepted in this way must also be presented at the symposium. The second, December 16, is for authors that wish to present their work or work-in progress at the symposium first without submitting to the full review process for publication. These authors can then take into account feedback received at the symposium and submit a full article for review by the third deadline, February 17. ## 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 2023 program chair, Stephen Chang. ## Best Paper Awards TFP awards two prizes for the best papers each year. First, to reward excellent contributions, TFP awards a prize for the best overall paper accepted for the post-conference formal proceedings. Second, a prize for the best student paper is awarded each year. 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. In both cases, it is the PC of TFP that awards the prize. In case the best paper happens to be a student paper, then that paper will receive both prizes. ## Instructions to Authors Papers must be submitted at: <https://easychair.org/conferences/?conf=tfp23> Authors of papers have the choice of having their contributions formally reviewed either before or after the Symposium. Further, pre-symposium submissions may either be full (earlier deadline) or draft papers (later deadline). ## Pre-symposium formal review Papers to be formally reviewed before the symposium should be submitted before the early deadline and will receive their reviews and notification of acceptance for both presentation and publication before the symposium. A paper that has been rejected for publication but accepted for presentation may be resubmitted 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. ## Program Committee Peter Achten, Radboud University Nijmegen, Netherlands Nada Amin, Harvard University, USA Ambrose Bonnaire-Sergeant, Untypable LLC, USA Laura M.
