Hi Olivier,
why not use RehearsalMark?
\version "2.17.5"
barMark = { \bar "||" \mark \default }
\relative c' {
\set Score.markFormatter = #format-mark-circle-numbers
c1
\barMark
e
f
\barMark
\break
g
}
A function is possible, too:
\version "2.17.5"
doubleBarMark =
#(define-music-function (parser location music) (ly:music?)
(music-map (lambda (m)
(if (eq? 'ContextSpeccedMusic (ly:music-property m 'name))
(let* ((elt (ly:music-property m 'element))
(prop-set (ly:music-property elt 'name))
(value (ly:music-property elt 'value))
(symbol (ly:music-property elt 'symbol)))
(if (and (eq? prop-set 'PropertySet) ;; needed?
(equal? value "||")
(eq? symbol 'whichBar)) ;; needed?
(set! m (make-sequential-music
(list (make-music
'SequentialMusic
'elements
(list
m
(make-music
'MarkEvent
'label '() )))))))))
m)
music))
%------- test
mus =
\relative c' {
\doubleBarMark {
c1
\bar "||"
e
f
\bar "||"
\break
g
}
}
musII =
\relative d' {
\key d \minor
\clef bass
\time 3/8
\bar "||"
a16-.-\upbow b (c) d(c) b (
a) b (c) d(c) b-\laissezVibrer \bar "||"
a16 (b) c(d) c(b)
a (b c d c) b-. \bar "||"
a b c d c b
a (b c d) c (b) \bar "||"
a (b) c-. d-. c b
a16 (b) c(d) c(b)
a (b c d c) b-. \bar "||"
a b c d c b
a (b c d) c (b) \bar "||"
a (b) c-. d-. c b
}
\score {
\new StaffGroup <<
\new Staff \doubleBarMark \musII
\new Staff \doubleBarMark \musII
>>
\layout {
\context {
\Score
markFormatter = #format-mark-circle-numbers
\override BarNumber #'stencil = #point-stencil
%\override RehearsalMark #'X-extent = #'(0 . 0)
\override RehearsalMark #'break-align-symbols =
#'(staff-bar time-signature key-signature clef left-edge)
}
\context {
\Staff
\remove "Time_signature_engraver"
\remove "Clef_engraver"
\remove "Key_engraver"
}
}
}
