Re: [Pharo-project] Spaktacualr Class Forest of Pharo

by HwaJong Oh

Actually, the cow will vary in size. Packages with classes those don't share superclass will be represented with big big big cow. That cow will be hiding most of other 3d objects with its huge back. And some cows will be small like an ant. Besides, cow will genreate lots of polygons. I have no idea presenting both hierarchy and package membership in one 3d space. All I can think of is filtering in classes with user selected package.

Re: [Pharo-project] [COTDC] 70 - DeflateStream

by laurent laffont

I'm the base class for "stream compressor". For example, my subclass GZipWriteStream can compress a stream contents using gzip algorithm. Try: gzData := String streamContents: [:aStream| (GZipWriteStream on: aStream) nextPutAll: 'Some data to be gzipped'; close. ]. Transcript show: gzData; cr; show: (GZipReadStream on: gzData) upToEnd; cr.

Re: [Pharo-project] support for flattening-out traits for export?

by Mariano Martinez Peck

Ok....since Martin is a shy guy I will speak in his name ;) Not sure if it is worth it for the thread, but just want to make clear why we used Traits. A couple of reasons: 1) Martin didn't have time to play with Traits before, and since he is a hacky guy he wanted to learn and try. Fuel has a particular problem, and he tried with Traits 2) In a couple of places we found Traits were easier than subclassifaction. So, we went ahead. 3) We were not aware of some problems of traits, and we discover them after. I cannot really reproduce or numerate them but some tools like OB, RB and Monticello are not fully working with them. 4) Martin was taught (mostly by Hernan Wilkinson I guess jajajaja) not to duplicate code at all. Maybe even too much ;) 5) I also liked when Martin put traits. 90% are used in tests. The little part of the core can be easily removed as Eliot suggested. Now, I am not saying whether Traits are useful or not. I just want to say why we used them. Now, if we re-think about them, as said, we may be able to refactor them and not used them and avoid code duplication.
