When I use the parenthesizeMusic function or the snippet in LSR-902 with a
winged repeat bar, the parenthesis collides with the bar. I have not been
able to find a way to pad the bar or the parentheses in a way that avoids
this.
[in this code I could simply reduce the font size, but that does not fix
the issue in my score]
\relative c''
{
\override ParenthesesItem.font-size = 7
\override ParenthesesItem.extra-offset =
#(lambda (grob) (cons 0 (* -1/2 (ly:grob-staff-position grob))))
g2 r4
\parenthesizeMusic {
d'8 bes8
}
\bar":|]"
}
