I found out the hard way that apparently adding \RemoveEmptyStaffContext globally to a score will erase some previous settings. In particular, if you have:
\layout {
\context { \Staff
ignoreFiguredBassRest = ##f
}
}
\layout {
\context { \RemoveEmptyStaffContext }
}
then the score will still use ignoreFiguredBassRest=##t (which is the
default). If you don't add the RemoveEmptyStaffContext, then ##f is used.
Attached is an example file displaying this behavior.
Is this a bug? In my eyes, it is quite severe, because it means you can't
trust lilypond any more. If you check e.g. the individual parts (which do not
add the RemoveEmptyStaffContext) for errors, you cannot be sure any more that
the full score or e.g. the choral score are correct, too!
Cheers,
Reinhold
PS: What is the reason anyway to have
ignoreFiguredBassRest = ##t
for the Staff context? Bass figures on rests ARE used and have a well-defined
meaning (namely that they take the next bass note as reference, but play the
harmony on the rest already). It seems that Han-Wen added this feature a while
ago and set the default to ##t, but didn't really give any good reason to
silently discart bass figures on rests...
So, are there any reasons against making ##f the default (i.e. NOT silently
discarding vital bass figures)???
