IWST Paper Submission Deadline is Approaching!
by Guillermo Polito May 13, 2024

May 13, 2024

Dear community, IWST invites everybody to submit full/short papers to be considered to be plublished in the IWST 2024 Proceedings. Papers can both be presented in the conference's IWST track and appear in proceedings independently of the initially submitted abstracts. Full/short paper submission deadline: May 19th, 2024 We are looking for papers of two kinds: - Short position papers (5 to 10 pages) describing fresh ideas and early results. - Full papers (more than 10 pages) with deeper description of experiments and of research results. Paper accepted for publishing will be published within a *CEUR-WS Proceedings>https://ceur-ws.org/*. Hence, both submissions and final papers must be prepared using the *CEUR ART style>https://ceur-ws.org/Vol-XXX/CEURART.zip*. We recommend to use the template in single column style, although you may use two colums. CEUR proceedings accepts papers in boths styles as soon as they follow the template and have 5 or more pages. The IWST team, Gordana, Guille and Steven https://esug.org/2024-Conference/IWST2024.html

[ANN] Pharo 12 Release !
by Esteban Lorenzano May 8, 2024

May 8, 2024

Dear Pharo users and dynamic language lovers: We have released Pharo <https://pharo.org/> version 12! What is Pharo? Pharo is a pure object-oriented programming language and a powerful environment focused on simplicity and immediate feedback. * Simple & powerful language: No constructors, no types declaration, no interfaces, no primitive types. Yet a powerful and elegant language with a full syntax fitting in one postcard! Pharo is objects and messages all the way down. * Live, immersive environment: Immediate feedback at any moment of your development: Developing, testing, debugging. Even in production environments, you will never be stuck in compiling and deploying steps again! * Amazing debugging experience: Pharo environment includes a debugger unlike anything you've seen before. It allows you to step through code, restart the execution of methods, create methods on the fly, and much more! * Pharo is yours: Pharo is made by an incredible community, with more than 100 contributors for the last revision of the platform and hundreds of people constantly contributing with frameworks and libraries. * Fully open-source: Pharo full stack is released under MIT <https://opensource.org/licenses/MIT> License and available on GitHub <https://github.com/pharo-project/pharo> ... more on the Pharo Features page <http://www.pharo.org/features>. In this iteration of Pharo, we continue working on our objectives of improvement, clean-up and modularization. Also, we included a number of usability and speed improvements. A complete list of changes and improvements is available in our Changelog <https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo120Chang…> Some highlights of this amazing version: Highlights New breakpoint system The debug point system is a breakpoint model that supersedes the previous implementation of breakpoints and watchpoints. They are configurable, composable, and extensible. The traditional breakpoints remain available, including conditional breakpoints, one-time breakpoints, and object-centric breakpoints. Additionally, there are new types of breakpoints, such as chained-breakpoints, which condition the activation of certain breakpoints on the triggering of others (e.g., breakpoint B only activates if breakpoint A is hit first). Debug points also feature a dedicated browser and integration options. Tools * Scalable fluid class syntax is now the default one * Preparing the introduction of the Bloc graphic system by migrating more tools to Spec2 widgets * Spec2 UI framework enhancements to support GTK 4 * Leaner version of the Metacello package manager * More robust and strict mode for FFI System * New architecture for refactorings and domain specific transformations * Code loading speed improvement * Fast browsing via fully optimized package tags * Optmized memory usage via optimized method protocols * Compiler simplifications and improvements Virtual machine * Massive image support with permanent space * String/ByteArray comparison speed up Development Effort This new version is the result of 1895 Pull Requests integrated just in the Pharo repository. We have closed 865 issues and received contributions from more than 70 different contributors. We have also a lot of work in the separate projects that are included in each Pharo release: * http://github.com/pharo-spec/NewTools <https://github.com/pharo-spec/NewTools> * http://github.com/pharo-spec/NewTools-DocumentBrowser <https://github.com/pharo-spec/NewTools-DocumentBrowser> * http://github.com/pharo-spec/Spec <https://github.com/pharo-spec/Spec> * http://github.com/pharo-vcs/Iceberg <https://github.com/pharo-vcs/Iceberg> * http://github.com/ObjectProfile/Roassal3 <https://github.com/ObjectProfile/Roassal3> * http://github.com/pillar-markup/Microdown <https://github.com/pillar-markup/Microdown> * http://github.com/pillar-markup/BeautifulComments <https://github.com/pillar-markup/BeautifulComments> * http://github.com/pharo-project/pharo-vm <https://github.com/pharo-project/pharo-vm> Contributors We always say Pharo is yours. It is yours because we made it for you, but most importantly because it is made by the invaluable contributions of our great community (yourself). A large community of people from all around the world contributed to Pharo 12.0 by making pull requests, reporting bugs, participating in discussion threads, providing feedback, and a lot of helpful tasks in all our community channels. Thank you all for your contributions.

"Atlas is a Spec application" â New blog post on all: objects all: theTime
by Koen De Hondt May 5, 2024

May 5, 2024

Dear Pharo users and developers, I added the next blog post <https://all-objects-all-the-time.st/#/blog/posts/8> to the series on Atlas, a new browser for Pharo. It describes the relationship between Atlas and Spec, the UI framework of Pharo. The blog post introduces the basic building blocks of the Atlas UI. It also explains the struggle with some aspects of Spec and the Morphic backend. Happy reading! Ciao, Koen

[Success Story] Support Wizard by Thales
by Marcus Denker April 30, 2024

April 30, 2024

Support Wizard by Thales =================== Support Wizard is an application developped by Pierre Laborde and Eric Le Pors, Global Design and Innovation Leaders at Thales. It is using the latest technological innovations from Pharo to create native and high-performance desktop human-machine interfaces (Bloc graphics engine, Toplo libraries and OS tools). The application is structured with the open-source component architecture framework Molecule. The simplicity and speed of production offered by Pharo and the power of its language allows Thales to focus our efforts on ergonomics and graphic design of the application to offer the best possible user experience.
