[Testers Required] New FreeType implementation using FFI
by tesonep＠gmail.com March 30, 2018

March 30, 2018

I have implemented the backend of FreeType using only FFI calls. So the whole implementation is in the image side, the current plugin has a lot of problems handling the release of the pointers. The new implementation is using the mechanism that is already present in UFFI to release the Heap pointers, so it should be more stable and easier to modify if there is an issue. The FT2Plugin is not used anymore in this version. I have tested it in the different platforms, but beside OSX I have only made a smoke test. I need some users to try it, so I ask you if you can test in different installations. The image can be downloaded from the CI 32 bits: https://ci.inria.fr/pharo-ci-jenkins2/job/Test%20pending%20pull%20request%2… 64 bits: https://ci.inria.fr/pharo-ci-jenkins2/job/Test%20pending%20pull%20request%2… Thanks to all!! Cheers. -- Pablo Tesone. tesonep(a)gmail.com

Strange deprecation of SystemVersion
by Stephane Ducasse March 30, 2018

March 30, 2018

Hi I do not really understand why fromShortVErsionString: and friends have been deprecated (that part I can understand) but why do they depend on an extension packaged in tests. Stef

Build 739 breaks project load initialization order?
by Martin McClure March 29, 2018

March 29, 2018

I have a project that loads via Metacello in builds up through build 738. In 739 the load fails with DNU. The failure is in a method I have specified via a #postLoadDoIt:. It fails because it sends a message to a pool variable, which is nil. However, it should not be nil because it should have been initialized by a class-side #initialize method in a prerequisite package. Again, this worked up through build 738. Any idea what changed in 739 that would cause this, and is this change intentional? Thanks, -Martin

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
