Subject: Error in resolving number of staff lines
Hello list,
the following snippet prints a value of 5 in both cases,
whereas the second system has
only four staff lines. What's wrong here?
Regards,
Marc
\version "2.15.41"
#(define (test-bar-print grob)
(let* ((staff-symbol (ly:grob-object grob 'staff-symbol))
(line-count (if (ly:grob? staff-symbol)
(ly:grob-property staff-symbol 'line-count)
0)))
(display "\nNumber of staff lines: ")
(display line-count)
(ly:bar-line::print grob)))
\layout {
\context {
\Staff
\override BarLine #'stencil = #test-bar-print
}
}
\new Staff {
s1 \bar ":|"
}
\new Staff {
\override Staff.StaffSymbol #'line-positions = #'(-2 0 2 4)
s1 \bar ":|"
}
You don't appear to have explicitly changed the number of lines. Use
\override Staff.StaffSymbol #'line-count = #4
and the result is correct.
