Hi list,
I am working on a little piece that's played as written;
after that, the musician has to turn the page upside down and play the
resulting notes.
I managed to get the clef displayed at the beginning and the end of each
line, and I can flip the clef ;-)
Unfortunately, overriding the Clef.stencil at the end of the line
changes the apperance for the clef in the next line, too.

\once\override Staff.Clef.stencil = #(lambda (grob)

#"clefs.G" #}))
\break
}
}
melody = {
\repeat unfold 16 { c'4 4 4 4 }
}
\layout {
\context {
\Staff
explicitKeySignatureVisibility = ##(#t #f #t)
explicitClefVisibility = ##(#t #f #t)

Is there an easy way to detect whether the clef is actually at the end
of a line, so that I can write (in pseudo-code)
if (at-end-of-line)
rotate the clef
else
print the clef
fi
Thanks in advance,
Marc
