Hi Joel,
Several of the scores used poly-mark-engraver from
<https://lsr.di.unimi.it/LSR/Item?id=976> (see also
<https://lists.gnu.org/archive/html/lilypond-user/2011-08/msg00157.html>),
and this now fails with
fatal error: cannot find music object: MarkEvent
(Minimal example below signature; the demonstration included in
<https://lsr.di.unimi.it/LSR/Snippet?id=976> also fails the same way.)
This is both a bug-report if anyone’s maintaining the snippet, and a
question whether there’s now a better way to write da capo, al segno,
and other coda-like repeats.
Indeed there is. There's heavy ongoing (or by now maybe even finished?)
work by Dan Eble on precisely this group of features. I write this here
because (if I'm not mistaken) Dan is one of the few developers who do
not follow the lilypond-user list.
