[Moose-dev] Custom primitives wit Meta/Famix?

I am working on the handling of primitives in FM3 and Famix 3, and would like to make a small survey on how primitives had been used in Famix 2 - who used the custom primitives fature in Meta? - who added a custom primitive other than Timestamp/Date/Time? - which primitives are you missing? I saw that dates are used in many projects (Chronia, Dude, etc...) and hence suggest to include them in FM3 as built-in primitives. The list of primitives is thus String Boolean Number Date (new) with MSE format string ::= ( "'" [^']* "'" )+ boolean ::= "true" | "false" date ::= digit{4} "-" digit{2} "-" digit{2} ( ","digit{2} ":" digit {2} ":" digit{2} ) number ::= "-"? digit+ ( "." digit+ )? ( "e" ( "-"? digit+ ))? @toon, can you extend the MSEParser in Smalltalk to recognize this token? I have only poor Store access here. cheers, AA
