Hi Aaron,
What if I want to change this for each different length? Really long
ones and medium long ones, for example. Ideally I'd just like to be
able to specify a percentage or absolute offset where the flare
starts, for each different hairpin. That would be the simplest.
Something like:
\flare 0.05 % percent of length start
elbowed-hairpin is already relative (i.e. percentage-based) to the width
and height of the hairpin.
If you need absolute, you could do a little math based on the estimated
width of the normal hairpin stencil:
%%%%
\version "2.19.83"
abs-hairpin = #(define-scheme-function (elx ely) (number? number?)
(lambda (grob)
(let* ((sten (ly:hairpin::print grob))
(xex (ly:stencil-extent sten X))
(yex (ly:stencil-extent sten Y))
(width (interval-length xex))
(height (/ (interval-length yex) 2))
(x (- 1 (/ elx width)))
(y (- 1 (/ ely height))))
(elbowed-hairpin `((0 . 0) (,x . ,y) (1 . 1)) #t))))
{
\override Hairpin.height = 2
\override Hairpin.stencil = \abs-hairpin 1.5 1

c''4^\< \repeat unfold 4 { c'' } c''\!
c''4^\> \repeat unfold 6 { c'' } c''\!
c''4^\< \repeat unfold 8 { c'' } c''\!
}
%%%%
Haven't tested this much with broken spanners, so there may need to be
additional work.
