Currently I'm testing LSR-upgrade to current master, anticipating the
next stable. In the past doing so served me well as soon as the next
stable is actually out and updating LSR is really a TODO-NOW.
I stumbled upon a handful snippets (I may post about them, if I don't
find my way), one of them is incipit.ly,
https://lsr.di.unimi.it/LSR/Item?id=582
It works fine with 2.22. and before, I wonder why #4084 raises its
head now and not before.
Wouldn't it be a possibility to just change our `incipit':
$ git diff
diff --git a/ly/property-init.ly b/ly/property-init.ly
index f8e6ee37be..c0605757be 100644
--- a/ly/property-init.ly
+++ b/ly/property-init.ly
@@ -323,6 +323,7 @@ incipit =
\override InstrumentName.self-alignment-X = #align-x
\override InstrumentName.self-alignment-Y = #align-y
instrumentName = #instrument-name
+ measureBarType = ##f
}
{
$incipit-music
At least it fixes the here reported bug.
Thanks,
Harm
