[INFO] exporting and importing code with Tonel

by Davide Varvello

Hi Guys, I've to move my code from Pharo8 to Pharo10, here: https://lists.pharo.org/empathy/thread/BMON6SATURPEHBHCWYOMOXCYMWEK7YE6?has… , Esteban suggests to use Tonel, I've no experience with it and after looking for info on the web, I summarize here these 2 statements To export a package named MyPackage: [ :packageName :directory | Â Â Â TonelWriter fileOut: Â packageName asPackage mcWorkingCopy on: directory. ] value: 'MyPackage' value: '/aSelected/directory' asFileReferenceÂ To import the package into another image: (TonelReader on: '/aSelected/directory' asFileReference Â fileName: 'MyPackage') version load. HTH Cheers Davide

Hi Esteban, I gave Tonel a chance, It worked. The documentation about Tonel is 0, I'm going to write an email to the mlist with a couple of basic tonal commands for future help.

by Esteban Lorenzano

hi, some questions :) 1. why you are importing from cs? In pharo 8 there was already other formats available, including tonel. 1. Are you sure your missing class is not in another .cs you should install before? 2. In that sense, it would help to know which class is missing, we don't know if this is yours, ours or from an imported dependency.

Porting Pharo8 code to Pharo10

by Davide Varvello

Hi Guys,I can't port my Pharo 8 code to Pharo 10.Â I'm filing out my packages to a .cs file, but when I install it on Pharo 10 it shows an error that one of my class is missing, even if it is in the .cs file. Any hints? TIADavide

Pharo needs you! Call to save the Pharo UI

by stephane ducasse

Hello people If you want that Pharo just do not endlessly stay with such a crappy UI we all know, please consider joining the effort. We should make sure that as a general principle, a model MUST not refer to a UI. So that we can change the UI. We are working on it. But we need help. We should (1) Migrate last cool Morphic-based tools such as Finder, Settings to Spec2, FileList to Spec (2) Remove dependencies from Domain objects to Morphic (obviously) - remove to UIManager first from code outside Morphic. As a general principle please watch http://rmod-pharo-mooc.lille.inria.fr/AdvancedDesignMooc/Videos/M03_S5.mp4 http://rmod-pharo-mooc.lille.inria.fr/AdvancedDesignMooc/Videos/M09_S4.mp4 It looks basic but it is so true. Current status (1) Hernan started to work on the Setting Browser I know someone started to work on Finder but I think the effort was stalled. We need help there. (2) We started to clean the refactorings and we are making progress but this is slow. I started to remove references to UIManager because it should go away. In Spec we introduced dialog, check the examples in subclasses of SpDialogPresenter In addition, an application is able to create some default dialog check ui - dialogs in SpApplication I introduced a simple notification center that should play a kind of growl.

Open Call: Object-Centric Breakpoints experiment

by Steven Costiou

Dear Community, 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

Server socket: can not accept if backlog < 2

by Martin Fischer

Hi all, I'm in the process of learning pharo. As an exercise I'm implementing a "Inter-VM Object channel": - objects serialized/deserialized via Fuel - bidi channel connects 2 vm's - sendObject and receiveObject as api - transport configurable as either Socket or SharedMem (as an opportunity to learn the threaded FFI stuff) During the implementation of the server socket side, I stumbled over a strange behavior when the backlog is set to a value less than 2: Here is a simplified version of the server side: listeningSocket := Socket newTCP. listeningSocket listenOn: 19999 backlogSize: 1. "NOTE the 1 here!" clientSocket := listeningSocket waitForAcceptFor: 30. ... When a client connects: echo Hallo | nc -v 127.0.0.1 19999 listeningSocket waitForAcceptFor: is unblocked and signals an error which I think is then masked by another error which is: "SocketError: cannot access socket error code" which is raised from Socket primSocketError: Note that no error is signaled as soon as the backlog size is 2 or more. - Is there a reason for this behavior or is this a bug? - Is my analysis correct that the original error is hidden by another error that is raised during handling of the original error?
