In yum this would be a simple searchProvides(), which in theory is
mapped to PK's "what_provides" API. However PK explicitly disallows '*'
among other characters (via. pk_transaction_search_check()).
I assume this is intended, as other backends might not be able to
provide this functionality easily.
I'd say that probably your best bet would be to "de facto standardize"
something like the fonts or mime-type provides. So anything providing an
Anjuta plugin file would provide something like (just making something
really simple up):
...then you could do a search on the bare provides name. A hackier way
(which might have easier to use APIs) would be to (ab)use the mime-types
