Hi everybody!
I think it would be useful to add a repeat-type "none" to the
repeat-types-alist in unfold-repeats (music-functions.scm), e.g.
(define-public (unfold-repeats types music)
"Replace repeats of the types given by @var{types} with unfolded repeats.
If @var{types} is an empty list, @code{repeated-music} is taken, unfolding
all."
(let* ((types-list
(if (or (null? types) (not (list? types)))
(list types)
types))
(repeat-types-alist
'((volta . volta-repeated-music)
(percent . percent-repeated-music)
(tremolo . tremolo-repeated-music)
+ *(none . music)*
(() . repeated-music)))
An example that demonstrates the reason for my request is attached. Any
objections?

\version "2.21.0"
% Define all the music first
start = \relative { \repeat volta 10 { c'4 d e f } }
endA = \relative { g'2 a4 b c1 }
endB = \relative { g'2 f4 d c1 }
music = #(define-music-function () () #{ \start \end \bar "|." #})
% book template
mybookdef = "
\book{
\bookOutputSuffix \bookName
\paper{
system-count = \mysyscount
}
\score {
\unfoldRepeats \repList { \music }
\layout{ }
}
}
"
mybook = #(define-scheme-function () ()
(ly:parser-include-string #{ \mybookdef #}))
% "none" is not a valid 1st argument to \unfoldRepeats,
% but the default action (ignore \unfoldRepeats) is what we want ;-)
repList = none
bookName = "A" end = \endA mysyscount = 1 \mybook
bookName = "B" end = \endB mysyscount = 1 \mybook
repList = volta
bookName = "C" end = \endA mysyscount = 2 \mybook
bookName = "D" end = \endB mysyscount = 3 \mybook
