I found a way that makes the ly a little cleaner. acceptWithTag = #(define-music-function (parser location tag music) (symbol? ly:music?) (music-map (lambda (m) (let* ((tags (ly:music-property m 'tags)) (res (memq tag tags))) (if res (let ((void-music (ly:music-property m 'void))) (if (ly:music? void-music) void-music m) ) m))) music)) void = #(define-music-function (parser location music) (ly:music?) (make-music 'SequentialMusic 'void music)) sampleNotes = \relative c' { \partial 2 e e | c c c c | e2 \tag #'unfolded \void \bar "||" \repeat volta 2 { e4 e | e e e e | } \alternative { { d2 \tag #'unfolded \void \bar "" } { c2 \bar "|." } } } \book { \score { \unfoldRepeats \acceptWithTag #'unfolded \sampleNotes } \score { \sampleNotes } } _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
