How would I use for-each here? I’m not familiar with that.
you use define-scheme-function instead of define-void-function.
Ah, I see. I wouldn’t have thought that a function which basically runs print-book-with-default would classify as a void function.
Thanks for the enlightenment. Yours, Simon _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
