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

by Alain Busser

As I have seen, BYOB allows to build objects (hence its name) and program with objets. It is a functional language and allows recursivity. But its creator is porting it to JavaScript, under the name of "snap!" (if it is to find it easier with Google he may have surprises :-D). It is possible to beta-test it online, and I found it veeeeeryyyyyyy slow! So having a Scratch-like which would run on all the platforms and not too slowly, would be great (if only, because a tablet don't have a keyboard and it is easier to program "Ã la Scratch" when you don't have a real keyboard). By the way, Scratch is being ported to flash (instead of Squeak). If anyone understands why I would appreciate to know; I don't understand the logics...

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 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 In addition may be this code is really outdated so may be packaging it in a separate package for archival would make sense.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.

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. Then, about the files to download, there are some changes inside the skin folder to integrate BYOB.
