And if so, where should I define that?
I have now managed to handle what I need by adding a Scheme predicate and a C++ enum. However, I am quite sure that they are not implemented at appropriate locations: The Scheme predicate at the top of define-context-properties.scm The C++ enum directly in the .hh file where it is used. Where should I put them? Best Urs _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
