[ANN] Phratch: Scratch on Pharo2.0
Hi Pharoers, I am porting Scratch and BYOB on Pharo 2.0. The name of the project is Phratch. To begin, I took Scat (a port of Scratch on Pharo1.3) and modify it to make it work on Pharo 2.0. For that I integrated FileSystem. Then, I took BYOB and port it in the project. I have some bugs, but the main features are working. The main issue is that it is slow. I will investigate that too. The goal for me is to use it for teaching software engineering and robotics. I hope to use Phratch and Pharo 2.0 to create new features. The project is on SmalltalkHub, and a google code page is available, mainly for reporting issues: https://code.google.com/p/phratch/ To download Phratch, just run this code: Gofer it url: 'http://smalltalkhub.com/mc/JLaval/Phratch/main'; package: 'ConfigurationOfPhratch'; load. (Smalltalk at: #ConfigurationOfPhratch) loadBleedingEdge. Cheers, Jannik

I loaded it using the pharo20 one click. But it does not work. Apparently got blocked in WeakSet something. Loading NScratchâ¦. I reloaded. And it seems ok. How do we open Scratch?

This code should be something like this: packageName := aString. packages := RPackageOrganizer default packages select: [ :each | each name = packageName or: [ each name beginsWith: packageName, '-' ] ] sadly, that's incredible slow, so, we changed.

Strange, it works for me...
I reloaded. And it seems ok.
How do we open Scratch?
When the load is finished, a workspace is opened with this line: ScratchFrameMorph open Cheers, Jannik

Jannik, you should write to the Scat list. Joan and I kind of gave up about two years ago but there has been some new people (Irfan khan, Dave Mason, ...) contributing a bit to the project. These were our last news right before giving up: https://code.google.com/p/scat/wiki/PublicRelease By the way, the source code was also moved to stHub: http://smalltalkhub.com/#!/~bromagosa/Scat, I've just added you as a contributor. Cheers, Bernat. 2013/3/24 jannik.laval <jannik.laval@gmail.com>

Hi, I just merge your last changes with Phratch source-code. I think you shoud try Phratch and see the bug tracker of Phratch, because I added some. What I did in Phratch, is that it does not break the Pharo image. There is no other modifications than in the package of Phratch. I saw that Scat modify Morphic and Graphics to add some instance variables, that I don't have in Phratch. I saw also your bug-tracker and I resolved some issues: PNG transparency, Camera images, and a part of GIF import. What is the Scat mailing list ? Like that I can communicate directly with the team.

;-) Great!
Hi Jannik, Great! Thanks for taking this project further on, maybe someday we'll finally have a working Scratch on Pharo... :) The mail list is scat-project@googlegroups.com. Cheers! Bernat. 2013/3/25 jannik laval <jannik.laval@gmail.com>
