I'm not sure yet how to improve support for libtool convenience libraries, as they are used in different ways in different projects (regarding function exporting and API merging). I think that we can build functionality for convenience libraries on top of the current proposal, so I'll postpone thinking about this in detail. There should be no regression compared to the current implementation in that regard. I'm not opposed to, for example, adding --header-internal and --vapi-internal options to allow the generation of .h and .vapi files for the internal API. This should be quite easy to add later on. Not so sure about merging .vapi (and .h?) files. Jürg _______________________________________________ Vala-list mailing list Vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
