Hi Janek,
I don't think it's a bug, but the default behaviour.
It's possible to change with:
\version "2.14.2"
#(define my-bar-glyph-alist
'(("|s" . ("|" . "|"))))
#(define (my-bar-line::calc-glyph-name grob)
(let* ((index-cell (lambda (cell dir)
(if (equal? dir 1)
(cdr cell)
(car cell))))
(glyph (ly:grob-property grob 'glyph))
(dir (ly:item-break-dir grob))
(result (assoc glyph my-bar-glyph-alist))
(glyph-name (if (= dir CENTER)
glyph
(if (and result (string? (index-cell (cdr result)
dir)))
(index-cell (cdr result) dir)
#f)))
)
glyph-name))
bars = {
\once \override Staff.BarLine #'glyph-name =
#my-bar-line::calc-glyph-name
\bar "|s"
}
{
\override Staff.Clef #'stencil = ##f
\override Staff.TimeSignature #'stencil = ##f
\bars a1 \break
\bars a1 \break
\bars a1
}
%{
{
\bar "|s" a1 \break
\bar "|s" a1 \break
\bar "|s" a1
}
%}
Cheers,
Harm
