Open Call: Object-Centric Breakpoints experiment
by Steven Costiou May 14, 2024

May 14, 2024

Dear Community, as part of a research project in the EVREF team, we are looking for people to participate to an empirical experiment on object-centric breakpoints - a debugging tool present in Pharo 9. Many people from the community already participated, and we thank them very much :) We are still looking for participants, we need 40 people to do the experiment! Please help us, in return it helps us understand better our tools and their impact and therefore build better tools for the Pharo community! For those who want to know a bit more, see my original email below. For those who just want to jump at the experiment, you can go there https://github.com/Pharo-XP-Tools/XPImageGeneration/tree/exp-ocd Thanks in advance :) Steven. --- We would like to invite you to participate to our experimental study on Object-Centric Breakpoints. This study aims to evaluate and to understand how Object-Centric Breakpoints impacts the debugging activity. This experiment takes place in **Pharo 9**. In this experiment, we ask you to solve 2 debugging tasks, one with standard Pharo tools and one other with Object-Centric Breakpoints. Between the two tasks, you will have to follow a tutorialand warmup tasks to learn how to use the tool. **How to Participate:** All instructions are here, please read them carefully: https://github.com/Pharo-XP-Tools/XPImageGeneration/tree/exp-ocd **About the Experiment:** The experiment last between 40 minutes and 2 hours. Participants should have experience with Pharo development and debugging. We recommend having more than 6 months experience in Pharo and debugging in general. You will gain insights into the Object-Centric Breakpoints approach and contribute to advancements in debugging research. Help us to build better debugging tools that help you debug! **Some constraints:** - You are not allowed to load external tools and baselines, but you can use anything that is in the base image - Please do the experiment in one shot if possible without interruptions - The experiment sends anonymous data to our inria server, please make sure that you have a valid internet connection - Please try to use the object-centric breakpoints when the experimental framework asks you to **Notes:** Participation is voluntary, and everything is anonymous. You can abandon the experiment at any point (and your data will be discarded). For any question, you can contact us: steven.costiou(a)inria.fr and valentin.bourcier(a)inria.fr Thank you for considering participating in our study. Your contribution will be valuable in advancing the field of debugging and helping us understand what tools we need to build for Pharo. Sincerely, Steven and Valentin, EVREF team, Inria

[ANN] Soil release v1
by Norbert Hartl May 8, 2024

May 8, 2024

...we said at last ESUG that there will be a release soonish but as usual it doesn't go that fast. But now we are very happy to announce that Soil has a first public release v1. So what is soil? Soil is an object oriented database in pharo <http://pharo.org/>. It is transaction based having ACID transactions. It has binary search capabilities with SkipList and BTree+ indexes. It aims to be a simple yet powerful database making it easy to develop with, easy to debug with, easy to inspect, ... More details at https://github.com/ApptiveGrid/Soil This release is still considered early stage because although in ApptiveGrid there are over 4000 instances of it and there are other users there isn't a wider range of use cases, yet. So it is not fully battle tested. This just as reminder when you start compaining I need somewhere to point my finger to and say "I told you!" ;) there are few things missing that you might expect like garbage collection, etc. So but it is definetely usable and awaiting the brave ones of you to try. Hopy you enjoy it! Norbert & Marcus

[ANN] Pharo 12 released !
by Esteban Lorenzano April 26, 2024

April 26, 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.

UKSTUG meeting - Tudor Gîrba: What exactly is Glamorous Toolkit? - 24 April 2024
by UK Smalltalk April 22, 2024

April 22, 2024

To some people Glamorous Toolkit is a Pharo environment. To others it’s a knowledge management system. Others might see a code analysis platform, a data visualization or an API browsing tool. Yet others see the graphical stack with its interactive editors. Glamorous Toolkit is all of these. But it’s really also none of these. These are merely examples of the many forms the environment can be molded to. And there can be many more. Glamorous Toolkit is primarily an environment that makes it possible to create many experiences seamlessly and contextually. This then leads to a new way of programming that we call Moldable Development. Tudor Gîrba is a software environmentalist and the CEO of feenk.com ( http://feenk.com/ ) where he works with an amazing team to make the inside of systems explainable. Much of the work is embodied in Glamorous Toolkit ( gtoolkit.com) a novel environment that enables moldable development. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/300575234/ ) to receive the meeting details. Don’t forget to bring your laptop and drinks!
