Hi,
I'd like to understand why the following function has no effect :
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.19.3"
myFunctionFalse = \override Score.BarNumber.break-visibility = ##(#f #f #f)
myFunctionTrue = \override Score.BarNumber.break-visibility = ##(#f #t #t)
myFunction =
#(define-music-function (parser location arg) (boolean?)
#{
\override Score.BarNumber.break-visibility = ##(#f $arg $arg)
#})
{
\myFunctionFalse
\repeat unfold 16 c'1
\myFunctionTrue
\repeat unfold 16 c'1
%%% no/wrong effect here :
\myFunction ##f
\repeat unfold 16 c'1
\myFunction ##t
\repeat unfold 16 c'1
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Cheers,
~Pierre
