[Pharo-project] [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
Hi Jannik, nice work ! When we start Scat, we have the same idea of using it for robotics and integrate alternate version of Scratch. But why fork the Scat effort with another Google project ? Regards, On Sun, Mar 24, 2013 at 8:56 PM, jannik.laval <jannik.laval@gmail.com> wrote:

Interesting ! I will see that. Who is active on this project ? Should it work on Pharo2.0 ? I am interesting if we can merge efforts. Cheers, Jannik On Mar 24, 2013, at 9:09 PM, Serge Stinckwich <serge.stinckwich@gmail.com> wrote:

No I don't think so. Recently someone start to work on a port to Pharo 1.4, but you are the first to start to work on Pharo 2.0.
I am interesting if we can merge efforts.
I guess your work will give a new boost ;-) Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://doesnotunderstand.org/
Hi Jannik and Bernat I was wondering if it is necessary to keep the CCodeGenerator and Primitives-Plugins inside the system. In addition may be this code is really outdated so may be packaging it in a separate package for archival would make sense. I'm surprised that so many classes do not have class comments :). BTW pay attention that - PhratchPreferences has the same disease that the old Preferences class (RIP). - SensorBoardMorph open in the class comment -> DNU - (PaintCanvas new brushCursorSize: 21 color: Color yellow) display -> DNU In fact this code is quite scaryâ¦. :) Jannik what is the different between byob and Scratch.

Yes, I just did it expecting remove it soon.
- SensorBoardMorph open in the class comment -> DNU

Thanks for the report
Jannik what is the different between byob and Scratch.
byob allows one to build its own block (http://byob.berkeley.edu/#download) Go to Variable categorie: there is a "new block" button. It does not work for now: It works only on my machine, I have to commit the code. Jannik

We could merge them. Just I saw that there is no update on the Scat Google code since 2011, so I create one. Then, about the files to download, there are some changes inside the skin folder to integrate BYOB. Cheers, Jannik

Yes we were not really active recently. Bernat Romagosa was the most productive guy until now. Maybe you can join the scat mailing list in order to talk about how to join our efforts: https://groups.google.com/forum/?fromgroups#!forum/scat-project There is some japanese people on the mailing-list, that might be interested by your work on BYOB. I was also interested by using Scat/Phrash with arduino. Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://doesnotunderstand.org/

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.

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.

Cool! Tim Rowledge is hackin on Scratch directly, with the aim of improving its code, particularly performance wise. You might want to drop him an email and see if you can make use of his efforts. frank
