Jean, thank you for this code producing line for me - only a change -
the arches up, not down - may you send me adjusted code please ?
Here you go:
\version "2.20.0"
#(define-markup-command (draw-horizontal-arches layout props len) (number?)
#:properties ((thickness 0.1)
(arch-length 5)
(arch-height 1.5)
(angularity 0.2)
path-markup)
(interpret-markup
layout
props
(make-path-markup
thickness
(let loop ((x-pos 0.0)
(path-acc '()))
(if (> x-pos len)
(reverse! path-acc)
(loop (+ x-pos arch-length)
(cons
`(rcurveto ,(* 1/2 angularity arch-length)
,arch-height
,(- arch-length (* 1/2 angularity
arch-length))
,arch-height
,arch-length
0)
path-acc)))))))
\markup \draw-horizontal-arches #20
\markup
\override #'(thickness . 0.2)
\override #'(arch-length . 10)
\override #'(arch-height . 3)
\override #'(angularity . 0.8)
\draw-horizontal-arches #20
Best,
Jean
