Looking for Metacello beta testers
by stephane ducasse Jan. 4, 2026

Jan. 4, 2026

Hello Under the radar, we are actively continiously cleaning Pharo deep core so that we can work on new features. For metacello, in Pharo 13 we introduced a strict mode (so that we can detect hidden dependencies), and other loading features to support module experimentations. It will make Pharo code more robust in the long term. Since a couple of months we are actively simplifying/cleaning Metacello (as the version available in Pharo) because we want to introduce new features such as the possibility to force the reload of baselines and others. Now the unit test coverage of metacello is quite low and we do not use/know all the features that are available and that you may rely on. So we would love to have beta testers that can just try to load their code in Pharo 14 alpha and report potential bugs or features drop we would have introduced. So do not hesitate and this is a nice way to help pharo S.

[DEBT 2026] Future Debugging Techniques Call for Papers, submission 7th of March 2026
by Steven Costiou Dec. 27, 2025

Dec. 27, 2025

DEBT 2026: Call for Papers ================================================================================ DEBT 2026, Workshop co-located with ECOOP 2026, Brussels, Belgium Fourth Workshop on Future Debugging Techniques (https://2026.ecoop.org/home/debt-2026#Call-for-Papers) ================================================================================ Important Dates ----------------------- * Abstract submission deadline: Sat 28 Feb 2026 * Paper submission deadline: Sat 7 Mar 2026 * Author notification: Wed 15 Apr 2026 * Workshop: Monday 29 June 2026 ================================================================================ DEBTâ26 is looking to advance state-of-the-art to debug modern software. We welcome researchers from all related areas aimed at helping with the hard task of diagnosing the root cause of bugs, including dynamic and static debugging techniques, online and postmortem debuggers, delta debugging, automatic bug finding, novel visualization techniques for debugging programs, etc. The workshop aims to gather the community and foster discussion from different perspectives. That is why we seek submissions in the form of papers as well as talks and tool demonstrations. The workshop is a venue for all approaches to debugging. A non-exclusive list of topics of interest is: * Debugging techniques, from static to dynamic techniques. * Innovative visualisation techniques. * Techniques targeted specific programming models and execution models (e.g., concurrent and parallel programming, microservices, distributed ledgers, web, etc. ) or hardware (e.g., debugging micro-controllers, mobile devices, Big Data applications, etc.). * Case studies and evaluation of such techniques, e.g., user studies on visualisation tools, debuggers, etc. * Surveys, taxonomies of bugs and bug patterns, and current practices/uses of debugging approaches. Papers must be formatted according to the guidelines for ACM sigplanpapers (\documentclass[sigplan,screen]{acmart}), seehttps://www.sigplan.org/Resources/Author/ <https://www.sigplan.org/Resources/Author/>for details. Submissions should be made via Easychair using the following link:https://easychair.org/conferences/?conf=debt2026 <https://easychair.org/conferences/?conf=debt2026> The accepted papers will be published in the ACM Digital Library, though authors will be able to opt out of this publication, if desired. At least one author of an accepted paper must register for the workshop and attend the event to present the work, and participate in the discussions. 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 your conference. The official publication date affects the deadline for any patent filings related to published work. Workshop Organizers --------------------------- * Burcu Kulahcioglu Ozkan, Delft University of Technology, Netherlands * Steven Costiou, Centre Inria de lâUniversitÃ© de Lille, France For more information see: https://2026.ecoop.org/home/debt-2026

Fw: Pharo CIG Crash Issue
by MORGAN LEE GUAN HAN Dec. 5, 2025

Dec. 5, 2025

Forwarding the original email. ________________________________ From: MORGAN LEE GUAN HAN <1211107272(a)student.mmu.edu.my> Sent: Saturday, November 29, 2025 12:08 AM To: Aik-Siong Koh <askoh(a)askoh.com> Subject: Pharo CIG Crash Issue Dear Pharo Team, I am currently attempting to replicate what Esteban Lorenzano did for this Youtube Video<https://www.youtube.com/watch?v=U9fpvZJaFx4> (Esteban Lorenzano - Pharo-CIG: C++ Interface Generator - 23 April 2025), which is to generate C Bindings for Pharo uFFI to call, in Windows 11. Unfortunately, I am unable to replicate the results of the video. The results of my attempts leads to Pharo's Virtual Machine crashing and exiting abruptly to the launcher. I am unable to find any logs for this, and would appreciate your support for this matter. OS: Windows 11 Clang: https://github.com/llvm/llvm-project/releases/tag/llvmorg-18.1.8 (LLVM-18.1.8-win64.exe) Pharo Template: Pharo 14.0 - 64bit (development version, latest) Pharo CIG Github: https://github.com/pharo-cig/pharo-cig Raylib: https://github.com/raysan5/raylib Steps to Reproduce Step 1: Create Image [cid:1a4a23bb-52e6-47a5-b0a7-b251d6ddc8ea] Step 2: Installing Pharo CIG Open Playground wtih 'Ctrl + O + P' (or 'Cmd + O + P'). Copy and paste the Installation Code from the Pharo CIG Github<https://github.com/pharo-cig/pharo-cig>. Click the "Do it All" green triangle button on the top left of the Playground Window. [cid:2a667f99-b808-4950-a40a-798054e502e4] Step 3: Installing Clang Download and run the Pre-built binaries from this Github page<https://github.com/llvm/llvm-project/releases/tag/llvmorg-18.1.8> according to your platform. The folder named LLVM should be in your "C:\Program Files" directory after installation for Windows 11. Other installation methods may be used according to your preference. Step 4: Installing raylib Download or clone the raylib Github repository<https://github.com/raysan5/raylib>. Extract the folder ('raylib-master') if you are downloading the repository. Place the folder in a directory of your preference. E.g "C:\Users\morgan\raylib-master" Step 5: Setting Pharo CIG Requirements CIG needs to be able to find the clang library. If it cannot find it automatically, set the location in LibClang>>unix64LibraryName, e.g. - Pharo CIG Github<https://github.com/pharo-cig/pharo-cig> Open System Browser with 'Ctrl + O + B' (or 'Cmd + O + B'). Create a "win32LibraryName" method in the LibClang class under the CIG-LibClang package to set your "libclang.dll" location. This method is missing from the default installation. Paste in this code (There may be whitespace character issues): win32LibraryName ^ FFIWindowsLibraryFinder new userPaths: #('C:\Program Files\LLVM\bin'); findAnyLibrary: #('libclang.dll') [cid:3241b208-b515-4b7b-98fc-45312ec65c82] Save and create the method with 'Ctrl + S' (or 'Cmd + S'). [cid:7d0e72f0-4086-411a-8e27-c2b11c4df817] Step 6: The Example Recipe from Github Open Playground wtih 'Ctrl + O + P' (or 'Cmd + O + P'). Copy and paste the example recipe from Github <https://github.com/pharo-cig/pharo-cig?tab=readme-ov-file> into the Playground. Configure the example recipe from Github<https://github.com/pharo-cig/pharo-cig?tab=readme-ov-file>. Change "import:" and "cIncludedPath:" directories according to your file structure. E.g '/home/esteban/dev/vm/raylib/src/raylib.h' â 'C:\Users\morgan\raylib-master\src\raylib.h' Click the "Do it All" green triangle button on the top left of the Playground Window. This should cause the Virtual Machine to abruptly exit or crash. Code Snippet (There may be whitespace character issues): (lib := CigCLibraryGenerator new) "Prefix to be added to the generated classes (structures, enums, etc.)" prefix: 'Ray'; "name of the generated package (by default, is the same as the libraryName, capitalized)" packageName: 'Raylib'; "Library name. If not unixLibraryName, macLibraryName and winLibraryName are specified, it will be taken as base name for the existing libraries (e.g. in this case raylib.so, raylib.dylib and raylib.dll)" libraryName: 'raylib'; "headers to import (there can be as many of them as is needed)." import: 'C:\Users\morgan\raylib-master\src\raylib.h'; import: 'C:\Users\morgan\raylib-master\src\rcamera.h'; "include path (-I of c compiler), to allow libclang to find other included headers." cIncludePath: 'C:\Users\morgan\raylib-master\src'; "Since this is a graphical library, instruct the library to run in mainthread (otherwise, default is 'same thread' which is the same thread the pharo is running)" useMainThread. "generate the library" lib generate. [cid:55b4605c-3b19-45f0-8ed8-ef9093b6fa89] End of email.
