Hi Lilypond Gurus! I need help, when you can spare the time, to get an already- working Lilypond music function to call my just-added Scheme routine.
This Scheme procedure works when called directly from Guile: entering "(colorNote -1)" get output "red". -------------------------------- (define (colorNote n) (cond ((eq? (- n) 1) 'red ) ((eq? (- n) 2) 'blue))) -------------------------------- But in trying to evoke the procedure, the following Lilypond function hits two snags: it apparently doesn't see colorNote at all, and even if it did, it still would not convert the returned "red" to "#red". (I've omitted irrelevant lines.) ---------------------------------------------------------------- FS = #(define-music-function (parser location offset) (number?) #{ \override NoteHead.font-size = #offset % This line works. %\override NoteHead.color = #red % This line worked. \override NoteHead.color = #(colorNote #offset) % *ERRORS*. #}) ---------------------------------------------------------------- I suspect that a fix here is easy. But it's beyond my naive struggles. I'd appreciate any suggestions.
