[Pharo-users] How do I find the RPackageTag of a class?

Actually - I’ve realised that Calypso can give me the tag name from its context - (aToolContext lastSelectedClassGroup).

However it does highlight a very strange package/tag design. Are you not supposed to be easily able to derive RPacakgeTags?

It seems different than Pharo6 at least with Nautilus (vs Calypso) - as previously the Nautilus UI gave me the RPacakgeTag, and I could just work with that. Calypso doesn’t seem to give me the tag object, but if I have a known class and I want to know its RPackageTag I can’t see how you do it? It all seems rather messy….

So am I really supposed to split the category name on “-“ myself, and then select the correct RPackageTag?
