Info required for bootstrapping pharo on GNU Guix
by Nicolas Graves May 21, 2024

May 21, 2024

Hi Pharo community, I'm trying to package pharo in the GNU Guix linux distribution. Since the distribution is focused on reproducibility and avoids using binary code when possible, for that I need to reproduce the bootstrapping steps that are embedded in Pharo. I understand from some developper online comment that this is possible. I've started to work on this and it seems feasible, at least I get the dependency loop, what I've some difficulty is to get precisely when it's possible to get started. ------------------- | v pharo VM pharo â§ | ------------------- If I'm correct, - bootstrapping is very clear after version ~7.0.0, and with a proper build, just follow the distribution numbers in wget's with a cmake build-system. - for earlier versions, there's the repository https://github.com/pharo-project/PharoBootstrap that seems (git history) to be able to go back to Pharo 30. - I understand that at some point, Squeak and Pharo used to have the same VM. I have access to a squeak-vm 4.10.2.2614 in Guix, and I've seen this is in Pharo's ftp files, so I guess I can start there. What I need: - Some indication about the first version of Pharo that I'm able to build purely from squeak-vm, and where to find its source code (git+version or commit if possible, I seem to only be able to find its binaries currently in phero's ftp files). - Any useful information for early bootstrap steps. Some useful information on my side: - During the build process in Guix, we can't download data, so the entire bootstrap chain has to be explicited at once, hence the need to go back to the beginning in this case. Thanks in advance! -- Best regards, Nicolas Graves

IWST Deadline Extension
by Guille Polito May 17, 2024

May 17, 2024

Dear Community, Please let us inform you that the submission deadline for the full/short papers has been extended until May 31st, 2024 AoE. Let us remind you of the submission details: - Short position papers (5 to 10 pages) describing fresh ideas and early results. - Full papers (more than 10 pages) with deeper descriptions of experiments and research results. Please also consider that you may submit another work other than your original abstract. 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 using the template in single-column style, although you may use two columns. CEUR proceedings accept papers in both 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

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 ð 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 ð 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
