Through this snippet https://github.com/stevage/Lilypond/blob/master/Documentation/snippets/fret-diagrams-explained-and-developed.ly
and this doc : http://lilypond.org/doc/v2.18/Documentation/notation/instrument-specific-markup I found out the function in the LSR http://lsr.di.unimi.it/LSR/Item?id=790 appends '(place-fret) to the (string fret) pairs and thus does not support the syntax to indicate open strings. "(open 4)" I changed the original function in the LSR to fix that and it works. % Expand the (string fret) pairs to valid lilypond syntax % ORIGINAL #(define (fret-from-list l1 l2 n1) (if (null? l1) l2 (fret-from-list (cdr l1) (append l2 (list (append '(place-fret) (car l1) (inverted (length l2) n1)))) n1))) % MODIFIED % to allow to use other syntax of the fret-diagram syntax. % the function accepts (string fret) pairs and i added a test to check if the first element of a % (string fret) pair is a number append '(place-fret) otherwise just return the list #(define (fret-from-list source target n1) (if (null? source) target (fret-from-list (cdr source) (append target (list (if (integer? (car (car source))) (append '(place-fret) (car source) (inverted (length target) n1)) (car source) ) ); list ) n1))) -- View this message in context: http://lilypond.1069038.n5.nabble.com/how-to-avoid-barre-and-fingerboard-shift-in-fret-diagram-tp167595p167630.html Sent from the User mailing list archive at Nabble.com. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
