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/

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.

We could merge them. Just I saw that there is no update on the Scat Google code since 2011, so I create one.

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 ?

[Pharo-project] [ANN] Phratch: Scratch on Pharo2.0

by jannik.laval

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

Normally, the main Seaside developers should have to do this, it is their (communities') code. Yes but we will probably have to do it because we could use Seaside as a nice regression tests for Pharo 30 apha. Stef
