Re: Inter-staff bar line for ChoirStaff?

[Valentin Petzel]

Hello Matthew,

and or can be done by (or ...), like (or somthing1 somthing2) (though you can 
have any amount of arguments).

But at some points you might want to do something like this:

\version "2.22.2"

#(define spanbars
   '("||" "|." ":|." ".|:" ":|.|:"))

\layout {
   \context {
     \ChoirStaff
     \consists Span_bar_engraver
     \override BarLine.allow-span-bar =
     #(lambda (grob)
        (member (ly:grob-property grob 'glyph)
                spanbars))
   }
}

\new ChoirStaff <<
   \new Staff { 1 1 \bar "||" 1 \bar ":|." 1 \bar ".|:" 1 \bar ":|.|:" 1 \bar 
"|." }
   \new Staff { \repeat unfold 6 c'1 }
 >>

or if you want to span anything BUT a normal barline you might want to use

(not (equal? (ly:grob-property grob 'glyph) "|"))

instead.

Cheers,
Valentin
