Re: bar number alignment

[Jean ABOU SAMRA]

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.

Close! Thank you Aaron.

I'd change the sign though : \override Score.BarNumber.self-alignment-X = #(lambda (grob) (+ (ly:item-break-dir grob)))

Cheers,

Pierre

Would something like this help?

%%%%
   \override Score.BarNumber.self-alignment-X =
     #(lambda (grob) (- (ly:item-break-dir grob)))
%%%%
