Hi,
trying to override Beam-stencil I need to read out the number of beams, the
space between the beams and the thickness of the whole beam (shown by the
red bracket). Of course I need only two of this values to detemine the
third, but I only managed to get the thickness of a single Beam.

In the little test-function below I have to put in the beam-count manually.
And the value of the between-beam-space is a guess.
\version "2.14.2"
#(define ((stencil-plus-bracket beam-count between-beam-space) grob)
(let* ((beam (ly:beam::print grob))
(beam-positions (ly:grob-property grob 'positions))
(single-beam-thickness (ly:grob-property grob 'beam-thickness))
(whole-beam-thickness (+ (* beam-count single-beam-thickness) (* (-
beam-count 1) between-beam-space)))
(bracket (ly:bracket Y (cons (* -0.5 whole-beam-thickness) (* 0.5
whole-beam-thickness)) 0.05 0.4)))
(ly:stencil-add
beam
(ly:stencil-in-color
(ly:stencil-translate
bracket
(cons -1 (- (car beam-positions) (* 0.38 whole-beam-thickness))))
1 0 0))
))
\relative c' {
\stemUp
\once\override Beam #'stencil = #(stencil-plus-bracket 3 0.35)
f'32 [f f f]
\once\override Beam #'stencil = #(stencil-plus-bracket 2 0.35)
f16 [f f f]
\once\override Beam #'stencil = #(stencil-plus-bracket 4 0.35)
f64 [f f f]
}
Any hint to improve?
Thanks,
Harm
