can't get keyboard shortcuts to work on Mac
by Gregg Williams June 3, 2018

June 3, 2018

I just can't get keyboard shortcuts to work on Mac. Iâve tried a lot of stuff, more than I can list here. Here are some things Iâve tried: * searching the Pharo by Example book * turning off all Mac keyboard-macro programs * switching from extended to standard US keyboard * looking at options in System Preferences > Keyboard I found some âunmapping option-key-plus-letterâ solutions at https://stackoverflow.com/questions/11876485/how-to-disable-typing-special-… â¦but yikes, that seems extreme! If youâre on the Mac, do you have this problem? If so, whatâs your solution? Thanks!

Problem with PharoLauncher on Ubuntu 18.04 (64 bit)
by Francisco Lizarralde May 31, 2018

May 31, 2018

Hi all, I was using the PharoLauncher (32 bits) version on Ubuntu 14.04 (32 bits) without problem. But two days ago I installed Ubuntu 18.04 (64 bits) and tried to run PharoLauncher-linux-1.1-x64 and when I tried to run a 6.1 image I got this message. Try this on a terminal: cd "/home/francisco/Pharo/vms/private/6521" && export SQUEAK_PLUGINS="" && "/home/francisco/Pharo/vms/private/6521/pharo" --nodisplay "/home/francisco/Pharo/images/Pharo 6.1 (stable)_1/Pharo 6.1 (stable)_1.image" eval "(Smalltalk imagePath asFileReference parent) / 'pharo.version' writeStreamDo: [ :stream | |major minor|major := SystemVersion current major.minor := SystemVersion current minor.(major = 6 and: [ SystemVersion current highestUpdate >= 60509 ])ifTrue: [ minor := 1 ].stream << major asString;<< minor asString ]" And got this: Error. Could not determine platform's libc path for VM. Try forcing $PLATFORMLIBDIR in /home/francisco/Pharo/vms/private/6521/pharo, based on LIBC_SO. Please report what works to pharo [vm-dev] mail list.

Is there a compatibility package for migrating Spec application from Pharo 6.1 to Pharo 7 ?
by Julien May 31, 2018

May 31, 2018

Hello, In Pharo 7, Specâs *Model classes were renamed following the pattern *Presenter, which is better. The original classes names (*Model) are still usable but their usage is deprecated in Pharo 7. I wonder if someone did a package for Pharo 6.1 that does the opposite: provide *Presenter classes in Pharo 6.1 to allow to prepare applications for the migration to Pharo 7 *but* allowing to keep them compatible with Pharo 6.1 until Pharo 7 is released (and eventually after...)? The implementation would be quite easy : create an empty subclass using the pattern *Presenter for the name for each *Model class of spec.

If a model has a list of things.. such as a user that can/may have lots of pets, are there any real benefits to initializing the list of pets lazily? like: self pets := OrderedCollection new. vs. pets Â pets ifNil: [self pets: OrderedCollection new] Â ^ pets thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Second Call for Papers: 11th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2018)
by Andrei Chis May 29, 2018

May 29, 2018

------------------------------------------------------------------------ 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 14 September 2018 - Artifact Kick-the-Tires Evaluation Author Response * 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 SLEâs 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 âTool Demoâ or âTool Demonstrationâ 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. --------------------------- 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 is provided on the conference 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 SIGPLANâs Republication Policy ( http://www.sigplan.org/Resources/Policies/Republication) Submitters should also be aware of ACMâs 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. --------------------------- Keynote --------------------------- We are very proud to announce that this yearâs SLE keynote will be given by Martin Rinard from the Massachusetts Institute of Technology. Martin Rinard is professor in the Department of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology, and a member of the Computer Science and Artificial Intelligence Laboratory. His research focuses on software systems and related topics. The broad goal of his research is to obtain better software - making software more robust, resilient, and secure, improving the performance, verifying that the software satisfies important correctness, acceptability, reliability, or accuracy properties, or making systems (both software and hardware) easier to specify, build, maintain, or improve. More information on his research can be found at http://people.csail.mit.edu/rinard/. Details about his keynote at SLE will be announced soon on the conference Website. --------------------------- Program Committee --------------------------- Andrew Black, Portland State University, USA Anya Helene Bagge, University of Bergen, Norway 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, Aston 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 LÃ¤mmel, 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 Markus Schordan, Lawrence Livermore National Laboratory, USA Anthony Sloane, Macquarie University, Australia Emma SÃ¶derberg, 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 --------------------------- Artifact Evaluation Committee (tentative) --------------------------- Arvid Butting, RWTH Aachen University, Germany LuÃs Eduardo de Souza Amorim, Delft University of Technology, Netherlands Anna Maria Eilertsen, University of Bergen, Norway Abel GÃ³mez, Open University Catalonia, Spain Marcel Heinz, University of Koblenz-Landau, Germany Ludovico Iovino, GSSI, Italy Jesper Ãqvist, Lund University, Sweden --------------------------- Contact --------------------------- For additional information, clarification, or answers to questions, please contact the organizers by email: sle2018(a)googlegroups.com.

Set Rounding mode for IEEE floating point operations
by Steffen MÃ¤rcker May 29, 2018

May 29, 2018

Hi, is there any way to set the rounding mode for IEEE floating point operations? Maybe something like > Double roundToMinusInfWhile: [... code goes here ...]Double > roundToZeroWhile: [... more code here ...] If not, is it possible to add this behavior, e.g., via a custom primitive? Best, Steffen
