REQUEST: #'omit and #'include options for \repeat unfold?
Hello all!
I’m just wondering whether it might be easy — and ultimately desireable — to
have a built-in method of choosing which grobs get repeated and/or omitted
during an unfold \repeat expression.
For example, in a string piece I’m currently writing, I have
\repeat unfold 2 { b8( d') b8( d') b8\downbow d'--(\upbow a--) }
I’d like the bowing to show up only on the first repeat, so it would be great
to have something like
\set repeatOmitInterfaces = #’(text-script-interface)
Another oft-encountered use case would be
\repeat unfold N { a4\pp a a a }
for which one currently must write
a4\pp a a a \repeat unfold N-1 { a4 a a a }
Note that I know of the “create a variable with tagged content” option, and
while it certainly has its place, it’s not nearly as user-friendly as the one
I’m suggesting here.
Cheers,
Kieren.

\repeat unfold N { \atrepeat{{a\pp}{a\ff}} a a a }
I think these should be relatively easy to implement in scheme,
provided you can examine the value of the current repeat counter.

Until somebody implements the requested options, we have to use parallel
music threads, one with repeated stuff, the other with the non-repeated
\new Staff \transpose c c'
\repeat unfold 16 { a4 b f g }
{ s4\pp\ s2 s4 s2\mp }
