I'm working on the "tie problem" in tablatures, that is, tied notes
should become invisible,
or (after a line break) parenthesized. I found
http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Difficult-tweaks#Difficult-tweaks
#(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 'extra-offset '(-2 . 5)))))
\relative c'' {
\override Tie #'after-line-breaking =
#my-callback
c1 ~ \break c2 ~ c
}
and wanted to use it as a starting point, but for my problem I have to
change the property of
another grob, namely NoteHead #'transparent (ok, after a line break
there should be parentheses
and I'm working on a Staff, not a TabStaff, but ...) How can I achieve this?
Is this even the right way to solve this task?
Marc
