I ask it that way because there are a couple of Kernel classes where I’ve seen this to not be the case. It would be nice that they get symmetric. because the goal of storeOn: is to recreate the same object. So if you have a fix please - sign the license agreement - open a bug entry - publish the fix.

Re: [Pharo-users] Initializing a class with a Dictionary
Hi sergio what do you want to do? Object subclass: #MyClass instanceVarNames: 'dict' MyClass>>initialize [ super initialize. dict := Dictionary new. ] MyClass>>atKey: aKey put: aVal [ dict at: aKey put: aVal ] MyClass>>atKey: aKey [ ^ dict at: aKey ] let you manage the key/val that you want? Let me know if this answers your question. Stef On 22/5/14 19:37, sergio_101 wrote: is it possible to initialize a class with a dictionary? my first thought would be to create a method like: intializeWithDictionary: aDictionary then, loop through the elements and do something like: instVarNamed: key put: value but the book says: Caveat: Although these methods are useful for building development tools, using them to develop conventional applications is a bad idea: these reflective methods break the encapsulation boundary of your objects and can there- fore make your code much harder to understand and maintain.-- should i avoid this? peace, sergio photographer, journalist, visionary #BitMessage BM-2D8VWUJSS41RFKh1ec83preVabHrnniExa http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Hello Arturo nice to see you more and more on this list :). Where is the code?

Please report problems by email to me directly. An advantage of this new packaging is that it should become much easier to create Ubuntu packages for your own Pharo projects. I will talk about that later as I try these new packaging mechanism on the Launcher, Pillar and Phratch projects. Its great that you are pushing all these installation and launcher methods. Thanks Damien. cheers -ben

Re: [Pharo-users] Versionner: Specifying un-configured packages as dependencies
+ 100 The reason is that any package* should be self described. Your configuration describes your project. If you use another piece of software, it should also be self-described. Let's take the following example: * for now, it's easy for you to add a direct dependency to Roassal2Spec, just as if it was a part of your project ... => no problem * ... but it is not. Maybe tomorrow, Alex will need to add a dependency to one or more packages for Roassal2Spec => you will have problems because you will not get these dependencies. Of course, you can still add them to your configuration but you can easily see that you will end with a configuration including all flatten dependencies, and with a lot of dependencies not directly related to your project (transitive dependencies). Flatten dependencies is really something that we should avoid, else maintenance of dependencies will be a hell. That's why I'm really in favor of having configurations, even for one single MC package inside the configuration. * I mean, not a Monticello package but a piece of software that you want to deliver independently. It may be a whole project or part of it. It may also refers to one or many Monticello packages

Re: [Pharo-users] 3D with Pharo and OpenGL ?
there are also my crappy tools that I develop to understand the wavefront format: http://smalltalkhub.com/#!/~jeanbaptistearnaud/ObjModel/source It is able to load .obj file generated from blender and integrate some material.
