Pharo application packager for OS X
by Christophe Demarey March 29, 2018

March 29, 2018

Hi, At this time, we do not have a utility to easily create an OS X application (dmg or pkg) from a Pharo image. It would be nice to have a tool like javapackager[1] but for Pharo. What does javapackager? It creates a pkg installer for OS X. At the end of the installation, you get an OS X application (you can specify the name, the icon, the version) that embed the JRE, the application jar file, the plist file, the resources, and a binary that I guess is small wrapper used to run the jre with adequate parameters. You can see at [2] how it is esay to build an app (even possible to sign it). I would like to have the same utility for a Pharo app. Instead of shipping a jar + the JRE, we ship Pharo VM + the image file. Nevertheless, I do not know a lot on OS X and I do not know what to do to create a wrapper for Pharo like the one of pkg installer. Does anyone have an interest to create it or can give information to build it? Regards, Christophe [1] https://docs.oracle.com/javase/8/docs/technotes/tools/unix/javapackager.html [2] http://centerkey.com/mac/java/

[Reflectivity] change regarding announcement in Pharo7
by Marcus Denker March 29, 2018

March 29, 2018

Hi, One questionable (but practical) thing that MetaLinks have is that they announce (MetalinkChanged) when they are installed or uninstalled. This is nice for being able to show them in the UI (and e.g. the Watcher implemented with them). But it is very very slowâ¦ so I now made it an option: https://github.com/pharo-project/pharo/pull/1160 <https://github.com/pharo-project/pharo/pull/1160> it is by default off, but can be turned on reflectively at any point. e.g. the link of the execution counter now looks like this: link := MetaLink new metaObject: self; selector: #increase; optionAnnounce: true. It has announcing enable so that the browser refreshes when it gets added or removed. Marcus

Some segfault crashes and freezes when trying to re-run saved pharo 7 images
by Thomas Dupriez March 28, 2018

March 28, 2018

Hello, I've had a few issues with Pharo 7 lately. After downloading pharo 7 images, doing some work in them and saving them, the images either instantly crashe or freeze when I try to re-run them. If that helps, I was working with and on the calypso browser. Attached are the crash dump files from some of these faulty images. vm version: 201708271955 image version: 6521 OS: Ubuntu 16.04 LTS Cheers, Thomas

Bloc: Simulating "Worlds"
by Sean P. DeNigris March 27, 2018

March 27, 2018

Posted to Discord, but the ML is probably a better venue for discussionâ¦ Looks like it's time for my annual Bloc Dream check in ha ha! Are we any closer to World simulation, meaning controlling all the dependencies (e.g. by a test harness)? We discussed this last year (http://forum.world.st/Bloc-Space-within-a-Space-tp4877474.html & http://forum.world.st/bloc-status-update-june-2016-tp4901988p4902319.html) and touched on it the year before (http://forum.world.st/Bloc-Roadmap-tp4816171p4816769.html) It's essential for the world to be built up from building blocks which make few assumptions other than their communication protocol and can be easily plugged in and out by a courageous user. A test case for this, which opens up many exciting possibilities (imagine I want to control time in my space e.g. run a simulation at 10x speed...), would be to have a world within a world. I dabbled with this idea a bit in Morphic, but quickly became frustrated because Morphic makes too many assumptions e.g. relying on globals and hardcoded classes. Smalltalk is at heart a simulation bench and the inability to simulate the IDE itself has felt like heavy shackles when I tried to implement several possible-blue-plane ideas in the past. Thanks for all the hard work pushing forward. I am persistent with this particular request especially because this use case forces a design that is very modular and testable, and is not something that could easily be "tacked on" late in development, but rather something that rightly should be baked in via TDD! ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
