I'm working a lot in GemStone and differences between the dialects are a real pain if you try to develop in pharo and deploy in GemStone. As we also need to exchange data we ported Sixx to GemStone. I've put Sixx in the configuration to keep the development of XML parser and Sixx close because Sixx relies on the interface of xml parser pretty much. As every module is a symbol there is no problem. And Sixx is not loaded by default. I know what is SIXX but to me you should write a ConfigurationOfSixx, if each package move its clients close to him then we will end up in a mess. > Sixx is a serializer/deserializer for XML and therefor is using streams. Streams are one of those fine examples where platform differences can drive you nuts. I couldn't understand all the fuzz of not using sport and preferring grease for seaside but only for seaside etc. I had a hard time dealing with platform subtleties for character encoding (yes, I care!) and streams when it comes to dialects. So I decided to introduce grease and made the GemStone port of Sixx depend on streams and character encoding behaviour of grease (Please sue me!). Dale was so kind to make even GemStone Core to depend on Grease to make Xml loadable by the core. But put that in ConfigurationOfSixx :) > Later I recognized that in pharo terms this is not possible.

Do not hesitate to ask questions! Smalltalk is different. And Pharo is not as cool as I would love it to be. But this is like that. I would like also it to be better. We are step by step getting there. I would like to have a small kernel that we can embed anywhere and that can talk to anything outside and a powerful set of tools and frameworks to load. We have nearly everything but some more work to do to get the full picture. Stef > Hi Max, > > Okay now I'm busy feeling pretty stupid.
