In the old scanner, the initialization of the type table just sets " binary token" as the default for all characters and changes some of them explicit to for example ($0 asciiValue to: $9 asciiValue) -> digit tokens #(9 10 12 13 32 ) -> delimiter token ... But RBScanner on the other hand explicitly sets some non-ascii characters to be used as "binary tokens" classificationTable at: 177 put: #binary. "plus-or-minus" classificationTable at: 183 put: #binary. "centered dot" classificationTable at: 215 put: #binary. "times" classificationTable at: 247 put: #binary. "divide" It looks like someone ( or somewhere ) it should be allowed to use these characters as a binary selector "#($Â± $Â· $Ã $Ã·)" Although later at the parsing step, using this tokens for binary message selectors isn't allowed. I think I will exclude these characters as binary selector tokens.

Re: [Pharo-dev] IceBerg and push for projects vs packages

by Nicolas Passerini

Well, I am not sure if this has to do with Iceberg itself, because Iceberg does nothing with dependencies. But I am not sure that a ConfigurationOfXXX really has information of only one package. Normally you will have only one configuration for each project, am I wrong? Then the configuration specifies (among other stuff) dependencies between the parts (packages) of your project... I think this is right. If you depend in another project, then you should not depend in specific packages but in another configuration. The problem here is that we are (at least Iceberg is) assuming a correlation between project and repository, because in fact Iceberg handles repositories. If a project would be spawn in several repositories, at least now Iceberg can't do anything about it, it will treat them as independent "projects". I am not sure about changing this logic in the near future, and also we should think if that is not a Cargo/Metacello feature.

Re: [Pharo-dev] Binary selector and special characters

by stepharo

This is a really nice and important question. I would really have a clear answer because it will make the system more stable. If you can build an analysis and let us know it would be really great. Something related but not on the same topic is that I would love to have a syntax for nested comments. This is really annoying to have to uncomment parts when we have to comment a large part. We discussed this back in 2007-2009 but we never did it.

Hi Glenn, Thanks a lot for this experiment. Could you send us the code snippet so people can play with it?
