Hello again,
I have a situation where I need to adjust the padding of an ottava
bracket after a line break. That is, I want to affect the bracket on
the second line, but not the first.
I know you can do something like this with the \shape function, but
what about brackets?
I tried this solution -- blatantly stolen from the Difficult Tweaking
section in the manual -- but it doesn't work.
%%%
\version "2.22.1"
#(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 'padding 4))))
\relative {
\override OttavaBracket.after-line-breaking = #my-callback
\ottava 1 c''''1 \break
c2 2
}
%%%
Anything easier than this? Some other solution?
It should be Staff.OttavaBracket because the
Ottava_spanner_engraver is in Staff context
(http://lilypond.org/doc/v2.22/Documentation/internals/ottava_005fspanner_005fengraver).
As Kieren showed, this is much easier done using
\alterBroken. The documentation was outdated, see
