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?

\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)))
\new Staff {
\override Staff.StaffSymbol #'line-positions = #'(-2 0 2 4)
s1 \bar ":|"
}
You are only overriding line-positions. While the bar line printer will
see that this now contains a value and heeds it, this does not magically
affect the (now ignored) line-count property.
Ah, I see, thanks for the explanation.
But why are the dots placed as if there were only four lines?
If the line number is still 5 and the routine in lily/bar-line.cc
works as expected, why are the dots placed correctly?
