Hello list,
I tried to simplify the make-...-bar-line functions
recently defined in scm/bar-line.scm.
However, if I replace the definition
(define (make-simple-bar-line grob extent thickness)
(let ((blot (if rounded
(layout-blot-diameter grob)
0)))
(ly:round-filled-box (cons 0 thickness)
extent
blot)))
with
(define (make-simple-bar-line grob extent thickness)
(let* ((extent (ly:grob-property grob 'bar-extent))
(blot (if rounded
(layout-blot-diameter grob)
0)))
(ly:round-filled-box (cons 0 thickness)
extent
blot)))
(I know that the argument 'extent' is redundant; I'll try to
reduce all arguments to 'grob' and calculate the rest from
inside the rooutine to make extensions easier...)
then I get:
Programmierfehler: vertical alignment called before line breaking
Fortsetzung, die Daumen drücken
when I try to compile a score with a span bar:
\score {
\new StaffGroup <<
\new Staff {
\new Voice {
c c c c
}
}
\new Staff {
\new Voice {
c c c c
}
}
>>
}
Can someone explain to me why this happens?
TIA,
Marc
