New Mars examples: Package Browser and Test Runner
by Carla F. Griggio Sept. 24, 2013

Sept. 24, 2013

Hi everyone! I want to let you know that I've just posted a screencast in my blog about the new Mars Package Browser and Test Runner<http://marsonpharo.wordpress.com/2013/09/24/marspackagebrowser-and-marstest…> . These examples are not really intended as being the definitive package browser or test runner, but to start experiencing how is it to build a real application using Mars and to showcase some widgets. Anyway, it's cool :) The Package browser is not so different to the system browser example I showed before, but the Test Runner is definitely my favorite example so far. I give more details in the screencast<http://www.youtube.com/watch?v=RlBr42uaqxE>and the blog post<http://marsonpharo.wordpress.com/2013/09/24/marspackagebrowser-and-marstest…>. Any feedback is appreciated! Cheers, Carla.

Encoding issues with DBXTalk
by Esteban A. Maringolo Sept. 24, 2013

Sept. 24, 2013

I'm trying to search for an object in the database by means of the following query: session readOneOf: User where: [:one | one name = 'MartÃn']. There is no matching row in the database. But I get the following error: DBXRecoverableError: RECOVERABLE OpenDBX: ERROR: invalid byte sequence for encoding "UTF8": 0xed 0x6e 0x27 On the other hand, if I insert a row manually, when I get the name back (read from the database) I get 'MartÃÂn' instead of the original 'MartÃn'. Should I define the encoding I want to use somewhere else? Regards, Esteban A. Maringolo

[ANN] Launching Pharo on Ubuntu
by Damien Cassou Sept. 23, 2013

Sept. 23, 2013

For Ubuntu users who are using my PPA (https://launchpad.net/~pharo/+archive/stable/) you can now launch Pharo from either the Ubuntu Dashboard or the terminal (just type 'pharo'). In both cases, you will see the Pharo Launcher from which you can create new images from templates on the web and launch existing images. http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher No need for manual download of zip files, unpacking, and directory management. The launcher does everything for you. Have fun -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Problems with Categories, PackageInfo and RPackage
by MartinW Sept. 22, 2013

Sept. 22, 2013

Hi, i am using the Spy framework in Pharo 2.0 which makes use of PackageInfo. It seems PackageInfo is not updated properly: Try this: PackageInfo allPackages size. 562 RPackageOrganizer default packages size. 540 SystemOrganization categories size. 476 Object subclass: #MyClass instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'MyNewCategory' PackageInfo allPackages size. 562 RPackageOrganizer default packages size. 541 SystemOrganization categories size. 477 And why are the numbers of PackageInfo packages, RPackage packages and categories so different in the first place? (I did file a bug for this: https://pharo.fogbugz.com/f/cases/11653) Now the question is, what can i do? 1) Hope someone fixes the PackageInfo updating? 2) Is there a guide for how to move something from using PackageInfo to RPackage? So i could try to change the relevant pieces in Spy?

[Voyage] Saving *ToMany references and dirty flag
by Esteban A. Maringolo Sept. 21, 2013

Sept. 21, 2013

How do you deal with the saving (and thus deleting/update) of dependant collections of a root (#isVoyageRoot) object? Could it be done as a two pass save? It is... to save first the object (like basicSave:id: now) and then walk through all its VOMongoToManyDescription's to save them (#basicSaveDependants). Which leads to another issue, how do you know when an object is dirty and needs to be saved? Because if we do what I proposed above it doesn't seem to be a good decision to save all referenced items everytime the root is saved. I have a strong ORM-shaped mind, and it's hard to break that, but is hard for me to have everything as part of a big document (BSON document), particularly almost all my objects are roots. Regards!
