But unfortunately it doesn’t work properly in 2.19.24 (and 2.18.2)
Yes, I think stems were reworked a lot around 2.16?
Here is that override approach with a duration condition:
%%%%%%%%%%
\version "2.18.0"
#(define (stem-stretch stem-tremolo-grob)
(let ((flag-count (ly:grob-property stem-tremolo-grob 'flag-count)))
(if (> flag-count 2) 1 0)))
#(define (longer-for-tremolo stem-grob)
(let* (
(stem-tremolo-grob (ly:grob-object stem-grob 'tremolo-flag))
(plain-stem? (< (ly:grob-property stem-grob 'duration-log) 8))
)
(+ (ly:stem::calc-length stem-grob)
(if (and (ly:grob? stem-tremolo-grob) plain-stem?)
(stem-stretch stem-tremolo-grob) 0))))
music = \relative {
b'1:32
b2: b4: b8: b:
b4:8 b:16 b:32 b:64
b!2:32 b8:16 b: b: b:
\tweak color #green b2:32 b
}
\markup "original LilyPond behaviour"
{ \music \stemUp \music }
\markup "longer-for-tremolo"
{ \override Stem.length = #longer-for-tremolo \music \stemUp \music }
%%%%%%%%%%
Cheers,
Robin
