Below I code for every "special" BarLine.
The LSR-snippet identifies whether an item is end-of-line, mid-line or
begin-of-line and modifies a grob-property relying on the result.
On a second look, this is possible here as well. Though, it's easier
to rely on the actual 'glyph-name as condition for the color.
Makes for:
\version "2.24.0"
#(define (color-certain-bar-lines color . barlines)
(lambda (grob)
(let ((glyph-name (ly:grob-property grob 'glyph-name)))
(if (member glyph-name barlines)
(ly:grob-set-property! grob 'color color)))))
colorRepeatBegSpecialBar = \once \set Score.startRepeatBarType = "[|:"
colorRepeatEndSpecialBar = \once \set Score.endRepeatBarType = ":|]"
music = {
b'1
\break % to show colored bar line
\colorRepeatBegSpecialBar
\repeat volta 2 {
c''1 |
\alternative {
{ d''1 | \colorRepeatEndSpecialBar }
{ e''1 | }
}
}
}
\score {
\new Staff \music
\layout {
\context {
\Staff
\override BarLine.after-line-breaking =
#(color-certain-bar-lines (x11-color 'orange) "[|:" ":|]")
}
}
}
HTH,
Harm
