I had some deprecation errors (which I fixed) and a single failing test (which I didn't fix), so I pushed a new version that you can get using Gofer new url: 'http://ss3.gemstone.com/ss/SDL'; package: 'Pastell'; load.

Actually, it seems I cannot. Or at least I do not know how. The problem is that Pastell is not mentioned in any group, and the 'default' group only points to Core. So, how do people load this?

Re: [Pharo-project] About ConfigurationOfXMLSupport

So it combines xml support technologies (otherwise it should be named ConfigurationOfXMLParsersAndDOM). I think Michael just dropped the name in and nobody changed it. The presence of Sixx and the dependency of Grease is my duty (I'm intentionally not writing 'my faul't). 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. 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. Later I recognized that in pharo terms this is not possible. I had a discussion with Sven because I wanted to have a zinc port for gemstone. But he was more interested to get zinc close to pharo. So the grease way was not an option and the result is the port to gemstone is still incomplete and hard to maintain. Sorry for the long answer but this is just another story of how hard it is to have modular systems where all of the mentioned issues wouldn't be that much of a problem. I would wish that we find a good solution to make sources more interchangable between platforms. I don't mean get rid of the dialect differences (because I don't think it will happen) but to design code in a way that platform subtleties can be compensated in an object oriented way. Norbert

But jaayer is the developer of the XML package. He picked up Michaels implementation and extended it. So there is only one guy that can give an elaborate answer. Hernan, I don't really understand your problem. It sounds like you need to mess with the method checkEOD in order to get your use case done. While the real problem is that SAX is about to read the whole file at once. And while this is inappropriate for a lot of cases StAX/pull parsers have been implemented. So the real issue is that there is no StAX/pull parser in smalltalk (or at least in pharo). Norbert

We remove the menu item because since full image contain packages that we do not know we could load updates that break them. Stef

We can ask giovanni because he wrote it. Doru you can use the ConfigurationOfXMLSupport to load it.

Hi Alain, By mistake I somehow did not see this mail. Thanks for the pointer. I did not know about it. Looking at the repository, there is no license. Of course, this can be just a mistake, but as it stands, it mean it is not open source.
