Actually it is a little more complicated.
The Repeat_acknowledge_engraver reads "defaultBarType" and takes it
into account.
Therefore the following works, although \bar "|" outputs _no_ barline
at line-begin:
\relative b' {
c1
c
\bar "|"
\break
\repeat volta 2 { d d }
}
Setting a different defaultBarType will work, too:
\relative b' {
\set Score.defaultBarType = #"||"
c1
c
\bar "||"
\break
\repeat volta 2 { d d }
}
In both examples the defaultBarType is recognized and the \repeat
command is not overridden.
And prints his own repeat-sign, taken from:
startRepeatType = #".|:"
which prints a _single_ barline at line end.
To get a double barline at line-end and a repeat-barline at line-start
you can let \bar ".|:-||" override the startRepeatType:
\relative b' {
c1
c
\bar ".|:-||"
\break
\repeat volta 2 { d d }
}
Or you can set this barline-type as the startRepeatType
\relative b' {
c1
c
\once \set Score.startRepeatType = ".|:-||"
\break
\repeat volta 2 { d d }
}
