Hi,
I'm the one who asked this question at first on -users-fr. Thank you very much
for this nice tweaking!
As bar numbers appearing at the end of a line should also be centered, I
ultimately settled on this code :
\version "2.21.0"
\layout {
\context {
\Score
\override BarNumber.break-visibility = ##(#t #t #t)
%% barNumberVisibility = #(every-nth-bar-number-visible 3) % for purpose of
demonstration -- uncomment if desired
\override BarNumber.stencil = #(make-stencil-circler 0.1 0.25
ly:text-interface::print)
\override BarNumber.self-alignment-X =
#(lambda (grob)
(define bd (ly:item-break-dir grob))
(cond
( (= bd 1) 0.8)
( (= bd 0) 0)
( (= bd -1) 0) ))
}
}
% now bar numbers are nicely aligned
\new StaffGroup <<
{ \repeat unfold 50 c'1 }
{ \repeat unfold 50 c'1 }
>>
Many thanks for your help.
Best regards,
Jean Abou Samra.
