I am one of the main authors and administrators, working on the python
script used to parse the GTK .h header files and generate the Fortran
interfaces.
Have you considered using the GObject introspection data that GTK itself generates, instead of your custom parsing code?
Concerning the "new discourse forum", I am not sure of what you mean. I do
not see such a forum on this page:
http://gtk.10911.n7.nabble.com/
If the "Gtk+ - General" forum is not the good place to post my message, I
apologize. It just seemed the less bad place for a Fortran thing...
Nabble is a web bridge to various mailing list; the "General" forum maps to
gtk-list gnome org, which is going to be de-activated on May 1st, 2019.
It seems Nabble does not respect cross-posting, so you probably haven't seen the announcement:
The tl;dr of it is: discussions about GTK (and language bindings) have been moved to Discourse:
and the existing mailing lists will be archived next Wednesday.
Ciao,
Emmanuele.
