AnnouncementSubscription and Ephemerons
by Torsten Bergmann April 2, 2018

April 2, 2018

Hi, by accident I stumbled upon the following code in AnnouncementSubscription: makeWeak action isBlock ifTrue: [ self error: 'Not currently available due to missing ephemerons support']. ... My understanding is that we have Ephemeron support in Pharo now working. Right? Anyone with more insights who knows how to fix/complete this? Should we at least open an issue? Thx T.

Roadmap to Pharo 7 Release
by Sean P. DeNigris April 1, 2018

April 1, 2018

Does a high level overview exist of what still has to be done? Do we expect any more potentially-disruptive changes or are we in/near the stabilization phase? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

Calypso: how to see two different methods (without diff) side by side?

Hi denis I do not really use a method diff but I would love to be able to see two methods side by side. Stef

Why calypso inverse the hierarchy?
by Stephane Ducasse March 31, 2018

March 31, 2018

Hi denis Calypso asked me where I want to install a method. And I do not really appreciate that I get the inheritance tree reserved. To me it will destroy students. On my own code which is super stupid I had to think twice. I cannot image students. Then when working on code that is not ours it is be super difficult to understand anything. How can I set that superclass should be higher than subclasses? Stef

Pavel's ChangeLog week of 2018-03-19
by Pavel Krivanek March 31, 2018

March 31, 2018

Hi, I did some serious Ring 2 refactorings that I wanted to have finished before the integration into Pharo. Because Pharo now starts to support the stateful traits, it needs to be supported by the metamodel too. However, we need to be able to model the images with the old traits as well and from the internal point of view, they are quite different. Moreover, if you load a code into the Ring model, you sometimes do not know if the behavior, where you load a method, is a class or you later will realize that it is a trait. The Ring 2 used for this a complex machinery that was able to switch the behavior kind using the #becomeForward: message. Some time ago I decided to solve both problems by introducing of the behavior strategies. That means that every behavior is a composition of an instance of the RGBehavior class and a behavior strategy (e.g. RGClassStrategy). Then changing of the behavior kind is then only a matter of swapping of the strategy (which has a state so it not so straightforward but still easy). The classes like RGClass or RGTrait are still present but now they are only the factories that produce the behaviors and they have no real instances. The next big thing I decided to do in Ring is renaming of the entities. From the beginning, I used the prefix "RG2" to avoid the collisions with the old Ring implementation but I supposed that before the final release it will be renamed because, from the user perspective, the Ring 2 should be a replacement for the old Ring and not completely separate project. The attempts to replace the old Ring with the new one showed me, that it is possible, but the old Ring is so deeply used in the system that it leads to a huge amount of instabilities. So I decided to rename the Ring 2 classes and some methods to do not make collisions with the old implementation. While the old Ring class was named RGClassDefinition and in Ring 2 it was RG2ClassDefinition, now it is renamed simply to RGClass. RG2Definition was renamed to RGObject. The only ugly exception is RG2Package which is now named RGPackageDefinition because the old Ring does not follow the naming convention and uses the name "RGPackage". The old Ring packages will get suffix "Deprecated" into their names. The old Ring and the Ring2 can coexist in one image and it is still possible to load the new Ring into the Pharo 6. Then I started to work on the changes metamodel for Ring with the goal to be able to record, reproduce and revert (almost) all changes that the user does in the model. The main goal of it is to be able to get comparisons of two models and compute loading order of the changes so it will be more easy to replace the Monticello metamodel and the metamodel for code differences with a single solid solution based on Ring. Cheers, -- Pavel

Why is FileSystem's Path class private ?
by Damien Pollet March 31, 2018

March 31, 2018

The class Path from FileSystem is documented as privateâ¦ but it should be public, shouldn't it? First hint is that it's named with a public name: (Path not FileSystemPath). Then, consider the following use-case : if you have a file name in some config file (.ini, .tomlâ¦) then that's really a Path, not a resolved FileReference. I'm not talking about RelativePath and AbsolutePath, those can be hidden away since Path provides the factory and DSL methods. IMHO they should still be renamed to a more private name. -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet

Migrator: to help you migrating to latest version of Pharo :)
by Stephane Ducasse March 31, 2018

March 31, 2018

Hi Today during the Pharo sprint I went over all the deprecated methods in Pharo 70 and Pharo 60 and I checked if I could convert the deprecated ones into deprecated:transformWith: so that the conversion is done automatically to help people migrating from one version to the other. I also collected all the deprecated methods as well as the new deprecated:transformWith: methods into a Package called Migrator (should still merge the Pharo 60 and Pharo 70 version). I plan to do the same for Pharo 50, 40, 30, 20. If you want to help feel free. At the end we will have one package containing all the deprecated methods of all the past versions. The way we will be able to support a smoother conversion to more recent version. Stef
