Hi Zachary,
I have found a way to use a scheme conditional to check if repeatcount
is greater than zero before evaluating repeat. Here's the snippet:
\version "2.20.0"
m = #0
n = #1
o = #2
\new Staff {
\repeat unfold #m dis'1
#(let ((x #{ \repeat unfold #m dis1 #}))
(if (> m 0) x))
#(let ((x #{ \repeat unfold #n d1 #}))
(if (> n 0) x))
#(let ((x #{ \repeat unfold #o des1 #}))
(if (> o 0) x))
}
I'm looking for a more elegant solution that doesn't have me going in
and out of scheme and lilypond. Please offer me some suggestions.
How about:
\version "2.22.0"
m = 0
n = 1
o = 2
empty-music = {}
unfold =
#(define-music-function (n mus) (index? ly:music?)
(if (positive? n)
#{ \repeat unfold #n { #mus } #}
#{ #} ))
\new Staff {
\unfold \m dis1
\unfold \n des1
\unfold \o dis1
}
Lukas
