Well, _every_ BarLine has some settings in the definition how to
behave mid-line, line-begin, line-end and for the span-bar-type.
\bar "||" doesn't print a bar-line at line-begin (see bar-line.scm)
The \repeat construct uses the value from 'startRepeatType' (see
engraver-init.ly) as starting repeat-sign, default and fall-back is
".|:" (see repeat-acknowledge-engraver.cc and look up how ".|:" is
defined in bar-line.scm)
While inputting
\bar "||" \break \repeat volta ...
you have two _conflicting_ settings at the _same_ musical moment.
One will override the other.
Clean sollution is to define a BarLine which has the settings you
prefer. This is done already with the predefined ".|:-||" (again, see
bar-line-scm).
Only thing I don't fully understand, why does "||" wins?
I'd expect the ".|:" to be printed.
Maybe of the internal representation of the music?
look at the terminal-output of:
\displayMusic
{
R1
\bar "||"
\break
\bar ".|:"
R1
}
\displayMusic
{
R1
\bar "||"
\break
\repeat volta 2 { R1 }
}
Not enough knowledge, though.
Cheers,
Harm
