The GHC developers are happy to announce the availability of GHC 9.4.5. Binary distributions, source distributions, and documentation are available at [downloads.haskell.org](https://downloads.haskell.org/ghc/9.4.5). Download Page: https://www.haskell.org/ghc/download_ghc_9.4.5.html Blog Post: https://www.haskell.org/ghc/blog/20230418-ghc-9.4.5-released.html This release is primarily a bugfix release addressing a few issues found in 9.4.4. These include: * Fixes for a number of bug fixes in the simplifier (#22623, #22718, #22913, 22695, #23184, #22998, #22662, #22725). * Many bug fixes to the non-moving and parallel GCs (#22264, #22327, #22926, #22927, #22929, #22930, #17574, #21840, #22528) * A fix a bug with the alignment of RTS data structures that could result in segfaults when compiled with high optimisation settings on certain platforms (#22975 , #22965). * Bumping `gmp-tarballs` to a version which doesn't use the reserved `x18` register on AArch64/Darwin systems, and also has fixes for CVE-2021-43618 (#22497, #22789). * A number of improvements to recompilation avoidance with multiple home units (#22675, #22677, #22669, #22678, #22679, #22680) * Fixes for regressions in the typechecker and constraint solver (#22647, #23134, #22516, #22743) * Easier installation of binary distribution on MacOS platforms by changing the installation Makefile to remove the quarantine attribute when installing. * ... and many more. See the [release notes] for a full accounting. As some of the fixed issues do affect correctness users are encouraged to upgrade promptly. We would like to thank Microsoft Azure, GitHub, IOG, the Zw3rk stake pool, Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, Haskell Foundation, and other anonymous contributors whose on-going financial and in-kind support has facilitated GHC maintenance and release management over the years. Finally, this release would not have been possible without the hundreds of open-source contributors whose work comprise this release. As always, do give this release a try and open a [ticket][] if you see anything amiss.

Pattern Synonym decls only at top level
by Anthony Clayden 18 Apr '23

18 Apr '23

" Pattern synonym declarations can only occur in the top level of a module. In particular, they are not allowed as local definitions. " says the User Guide. And the 2016 paper says likewise. But there's no explanation why. PattSyns are not necessarily declared in the same module as the underlying Datatype, so there can be a region of scope with the data constructor but without the PattSyn. If PattSyns are declared in the same module as their datatype, you can export the PattSyns but not the data constructors -- indeed that's a common way to keep the Datatype implementation abstract. Or (unusually) you can export the data constructors but not PattSyns. So there seems to be no close tie-up of Datatype/constructors and PattSyns. Then why couldn't a PattSyn be declared in local scope only? The builder function behind a PattSyn is just like any other function, so could be local(?) The paper's Implementation section 7 says the matcher also is an "ordinary function". Relatedly, PattSyns can in effect be overloaded: define the PattSyn in terms of a ViewPattern function. That can be a method of some class. Then why not more directly declare PattSyns within a class? [I have a feeling I answered a similar question on some forum, saying the PattSyn has to follow around its data constructors, like a dog on a lead. Can't find that now. If that was me, I apologise and withdraw.] AntC

[ANNOUNCE] GHC 9.6.1 is now available
by Ben Gamari 02 Apr '23

02 Apr '23

The GHC team is very pleased to announce the availability of GHC 9.6.1. As usual, binaries and source distributions are available at downloads.haskell.org: https://downloads.haskell.org/ghc/9.6.1/ Beginning with GHC 9.6.1, GHC can be built as a cross-compiler to WebAssembly and JavaScript. This is an important step towards robust support for compiling Haskell to the Web, but there are a few caveats to be aware of in the 9.6 series: - Both the Javascript and WebAssembly backends are still at an early stage of development and are present in this release as a technology preview - Using GHC as a cross-compiler is not as easy as we would like it to be; in particular, there are challenges related to Template Haskell - GHC is not yet run-time retargetable; a given GHC binary targets exactly one platform, and both WebAssembly and JavaScript are considered platforms for this purpose. Cross-compilers must be built from source by their users We hope to lift all of these limitations in future releases. Additionally, 9.6.1 includes: - Significant latency improvements in the non-moving garbage collector - Efficient runtime support for delimited continuations - Improvements in compiler error messages - Numerous improvements in the compiler's memory usage See the [release notes] for a comprehensive accounting of changes in this release. As always, one can find a migration guide to aid in transitioning from older releases on the [GHC Wiki][migration-guide]. We have also recently started extending our release process to cover a wider set of Linux distributions. In particular, we now offer Rocky 8 and Ubuntu 20.04 binary distributions which cover RedHat-derivative and distributions using older glibc releases (namely 2.27), respectively. Thanks to everyone who has contributed code, documentation, testing, and tickets to this release process. As this release represents upstream GHC's first step towards supporting web targets, we are very excited to have this release out the door! Cheers, - Ben [ticket]: https://gitlab.haskell.org/ghc/ghc/issues/ [migration-guide]: https://gitlab.haskell.org/ghc/ghc/-/wikis/migration/9.6 [release notes]: https://downloads.haskell.org/ghc/9.6.1/docs/users_guide/9.6.1-notes.html

CFP: Haskell Symposium 2023
by Trevor McDonell 24 Mar '23

24 Mar '23

=============================================================================== ACM SIGPLAN CALL FOR SUBMISSIONS Haskell Symposium 2023 Seattle, WA, USA Fri 8 -- Sat 9 September, 2023 http://www.haskell.org/haskell-symposium/2023/ ================================================================================ The ACM SIGPLAN Haskell Symposium 2023 will be co-located with the 2023 International Conference on Functional Programming (ICFP). As with last year, Haskell'23 will use a single-track submission process. That is, we will only have the regular track and no early track. The Haskell Symposium presents original research on Haskell, discusses practical experience and future development of the language, and promotes other forms of declarative programming. Topics of interest include: * Language design, with a focus on possible extensions and modifications of Haskell as well as critical discussions of the status quo; * Theory, such as formal semantics of the present language or future extensions, type systems, effects, metatheory, and foundations for program analysis and transformation; * Implementations, including program analysis and transformation, static and dynamic compilation for sequential, parallel, and distributed architectures, memory management, as well as foreign function and component interfaces; * Libraries, that demonstrate new ideas or techniques for functional programming in Haskell; * Tools, such as profilers, tracers, debuggers, preprocessors, and testing tools; * Applications, to scientific and symbolic computing, databases, multimedia, telecommunication, the web, and so forth; * Functional Pearls, being elegant and instructive programming examples; * Experience Reports, to document general practice and experience in education, industry, or other contexts; * Tutorials, to document how to use a particular language feature, programming technique, tool or library within the Haskell ecosystem; * System Demonstrations, based on running software rather than novel research results. Regular papers should explain their research contributions in both general and technical terms, identifying what has been accomplished, explaining why it is significant, and relating it to previous work, and to other languages where appropriate. Experience reports and functional pearls need not necessarily report original academic research results. For example, they may instead report reusable programming idioms, elegant ways to approach a problem, or practical experience that will be useful to other users, implementers, or researchers. The key criterion for such a paper is that it makes a contribution from which other Haskellers can benefit. It is not enough simply to describe a standard solution to a standard programming problem, or report on experience where you used Haskell in the standard way and achieved the result you were expecting. Like an experience report and a functional pearl, tutorials should make a contribution from which other Haskellers can benefit. What distinguishes a tutorial is that its focus is on explaining an aspect of the Haskell language and/or ecosystem in a way that is generally useful to a Haskell audience. Tutorials for many such topics can be found online; the distinction here is that by writing it up for formal review it will be vetted by experts and formally published. System demonstrations should summarize the system capabilities that would be demonstrated. The proposals will be judged on whether the ensuing session is likely to be important and interesting to the Haskell community at large, whether on grounds academic or industrial, theoretical or practical, technical, social or artistic. Please contact the program chair with any questions about the relevance of a proposal. If your contribution is not a research paper, please mark the title of your experience report, functional pearl, tutorial or system demonstration as such, by supplying a subtitle (Experience Report, Functional Pearl, Tutorial Paper, System Demonstration). Submission Details ================== Formatting ---------- Submitted papers should be in portable document format (PDF), formatted using the ACM SIGPLAN style guidelines. Authors should use the `acmart` format, with the `sigplan` sub-format for ACM proceedings. For details, see: http://www.sigplan.org/Resources/Author/#acmart-format It is recommended to use the `review` option when submitting a paper; this option enables line numbers for easy reference in reviews. Functional pearls, experience reports, tutorials and demo proposals should be labelled clearly as such. Lightweight Double-blind Reviewing ---------------------------------- Haskell Symposium 2023 will use 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 anonymised). 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. A reviewer will learn the identity of the author(s) of a paper after a review is submitted. Page Limits ----------- The length of submissions should not exceed the following limits: Regular paper: 12 pages Functional pearl: 12 pages Tutorial: 12 pages Experience report: 6 pages Demo proposal: 2 pages There is no requirement that all pages are used. For example, a functional pearl may be much shorter than 12 pages. In all cases, the list of references is not counted against these page limits. Deadlines --------- Paper submission: 1 June 2023 (Thu) Notification: 4 July 2023 (Tue) Camera ready: 18 July 2023 (Tue) Deadlines are anywhere on Earth. Submission ---------- Submissions must adhere to SIGPLAN's republication policy (http://sigplan.org/Resources/Policies/Republication/) and authors should be aware of ACM's policies on plagiarism (https://www.acm.org/publications/policies/plagiarism) Program Committee members are allowed to submit papers, but their papers will be held to a higher standard. The paper submission deadline and length limitations are firm. There will be no extensions, and papers violating the length limitations will be summarily rejected. Papers should be submitted through HotCRP at: https://haskell23.hotcrp.com/ Improved versions of a paper may be submitted at any point before the submission deadline using the same web interface. Supplementary material: Authors have the option to attach supplementary material to a submission, on the understanding that reviewers may choose not to look at it. This supplementary material should not be submitted as part of the main document; instead, it should be uploaded as a separate PDF document or tarball. Supplementary material should be uploaded at submission time, not by providing a URL in the paper that points to an external repository. Authors can distinguish between anonymised and non-anonymised supplementary material. Anonymised supplementary material will be visible to reviewers immediately; non-anonymised supplementary material will be revealed to reviewers only after they have submitted their review of the paper and learned the identity of the author(s). 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 conference chair 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. Proceedings =========== Accepted papers will be included in the ACM Digital Library. Their authors will be required to choose one of the following options: - Author retains copyright of the work and grants ACM a non-exclusive permission-to-publish license (and, optionally, licenses the work with a Creative Commons license); - Author retains copyright of the work and grants ACM an exclusive permission-to-publish license; - Author transfers copyright of the work to ACM. For more information, please see ACM Copyright Policy (http://www.acm.org/publications/policies/copyright-policy) and ACM Author Rights (http://authors.acm.org/main.html) Accepted proposals for system demonstrations will be posted on the symposium website but not formally published in the proceedings. Publication date: The official publication date of accepted papers 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. Artefacts ========= Authors are encouraged to make auxiliary material (artefacts like source code, test data, etc.) available with their paper. Authors can opt to have these artefacts published alongside their paper in the ACM Digital Library (copyright of artefacts remains with the authors). Artefacts must be included as part of their submission to HotCRP and should consist of a .zip file containing the artefact materials, a README explaining the contents of the artefact and how it should be used, and a LICENSE file. If an accepted paper's artefacts are made permanently available for retrieval in a publicly accessible archival repository like the ACM Digital Library, that paper qualifies for an Artefact badge (https://www.acm.org/publications/policies/artifact-review-badging) Program Committee ================= Alexander Green Standard Chartered, UK David Thrane Christiansen The Haskell Foundation, Denmark Edsko de Vries Well-Typed LLP, Netherlands Exequiel Rivas Tallinn University of Technology Facundo Domínguez Tweag Florian Zuleger TU Vienna, Austria Graham Hutton University of Nottingham, UK Jasper Van der Jeugt Snyk, Switzerland Jennifer Paykin Intel, USA Jesper Cockx Delft University of Technology, Netherlands Jose Nuno Oliveira University of Minho & INESC TEC, Portugal Michael Sperber Active Group GmbH, Germany Michel Steuwer University of Edinburgh, UK Niki Vazou (chair) IMDEA Software Institute, Spain Rumyana Neykova Brunel University London, UK Trevor L.

Type the following at the command line: xcode-select --install and then try ghci again. I'm not sure what you mean by "the software" in the phrase "Should I delete and reinstall the software you told me to install?" but in any case don't delete anything. Please try to be as specific as possible. When you first encounter a problem you should Google for a solution. If that doesn't work you can send mail to me but also cc ghc-devs(a)haskell.org and glasgow-haskell-users(a)haskell.org Cheers George On Thu, Mar 16, 2023 at 11:09 PM William McEnaney < bill.mcenaney.jr(a)gmail.com> wrote: > Hi, George, > > Sorry to bother you.

Hi Bill I'm cc'ing GHC dev and GHC users as someone else may have a better answer, catch a mistake I made etc. Please don't delete them. I believe you have encountered https://gitlab.haskell.org/ghc/ghc/-/issues/21506#note_447206 I believe the way to fix this is to do the following: rm -fr /usr/local/bin/ghc* rm -fr /usr/local/lib/ghc* ./configure sudo xattr -rc . sudo make install However I am unsure why you are encountering this as the issue is supposed to have been fixed.

Re: Installing GHC on my MacBook Air

Hi Bill, It's easy to forget to do replay all in gmail but it's important to do so in these emails. In your original email you wrote: After installing the compiler, my laptop said its processor was wrong for the binary distribution I chose. If there is a dmg file for *MacOS 12.5.1,* please please link your reply to it. Can you confirm that you no longer have the problem "of processor was wrong for the binary distribution I chose." ? My understanding is that after that you got the error: libHSterminfo-0.4.1.5-ghc9.4.4.dylib” can’t be opened because Apple cannot check it for malicious software. I then suggested you had encountered https://gitlab.haskell.org/ghc/ghc/-/issues/21506#note_447206 and I suggested you do: rm -fr /usr/local/bin/ghc* rm -fr /usr/local/lib/ghc* ./configure sudo xattr -rc . sudo make install You said you did and got a warning "that some program wanted to access my photos when I don't have any." Can you repeat those steps and cut and paste your terminal session into an email? Unfortunately I am too busy to continue replying but with the above I think somebody will be able to help you.

Hi William I think it's best if you submit a bug as described here <https://gitlab.haskell.org/ghc/ghc/-/wikis/report-a-bug> Whether in email or in the bug report it is critical that you describe how the reader can reproduce the bug, i.e. starting from the beginning, describe what you did and what error message(s) you got.

Bill For your latest problem libHSterminfo-0.4.1.5-ghc9.4.4.dylib” can’t be opened because Apple cannot check it for malicious software.
