An engraver is not a list, just like it isn't a string like "Note_engraver". That's just how you _specify_ an engraver. If it's a list, the Scheme_engraver type will be used for actually instantiating an engraver (which is bound to a particular context), initialized using the list contents. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
