Dear All, I have a piece of music with many slurs and sometimes I need to make a system break during a slur. With the current key (f minor) the default results are usually not that pleasing to the eye.
Luckily, I found a Scheme thingy on the mailing list for tweaking the broken slur at the beginning of a system. http://lists.gnu.org/archive/html/lilypond-user/2007-08/msg00539.html There's something odd in that, though. It seems that comments and spacing affects the resulting slur, which sounds weird. %%%% \version "2.11.39" \include "suomi.ly" \paper { indent = 0\mm ragged-right = ##t } #(define (my-callback grob) (let* ( ; have we been split? (orig (ly:grob-original grob)) ; if yes, get the split pieces (our siblings) (siblings (if (ly:grob? orig) (ly:spanner-broken-into orig) '() ))) (if (and (>= (length siblings) 2) (eq? (car (last-pair siblings)) grob)) (ly:grob-set-property! grob 'control-points '((4 . 3) (5 . 4.8) (10 . 5) (11 . 3.5)))))) %((0.3 . 1.8) (-0.3 . 3) (-2 . 3.5) (-3 . 3)) %((4 . 9) (6 . 13) (17 . 14) (21 . 12)) %((4 . 3) (5 . 4.8) (10 . 5) (11 . 3.5)) \relative c'' { \clef treble \time 4/4 \key f \minor %\once \rideover Srul #'sotipions = #'(0 . 1.0) g1 \once \override Slur #'after-line-breaking = #my-callback g2^( g4 g \break g2) g2 g1 % foobar } %%%% The broken slur reverts to default shape if I remove the line break above the % foobar, remove the %\once ... line, remove the \include "suomi.ly" line or remove the commented list of numbers below the Scheme function. The stuff on the %\once line probably doesn't have any effect per se because messing up the syntax didn't change the behaviour. Question one: If the Scheme is the culprit is there a way to fix it? Question two: Can I pass the control points as an argument? Question three: Is there another way to tweak the shape of the broken slur? -Risto
