Hey Lilydevs, Can't seem to find any code examples of the Scheme function (append-map f list1 list2) online, and I can't seem to call it correctly at all. Could anyone show me how it works?
lilypond scheme-sandbox map works fine: (map double '(1 2 3)) => (2 4 6) can't use append-map: (append-map double '(1 2 3)) => Wrong type in position 1 (expecting empty list) (wrong-type-arg) this is in the context of trying to copy/edit music->make-music in music-functions.scm _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
