Re: Vertical positioning of rests

[Leo Correia de Verdier]

I’m unsure if the following can count as an MWE, but here it goes:

%%%%%%%%%%%%%%%%%%%%%%
\version "2.22.1"

 #(define (move-rest-after-line-breaking grob)
                                   (let ((stil (ly:grob-property grob 'stencil))
                                         (y-offs (ly:grob-property grob 
'Y-offset))
                                         (staff-pos (ly:grob-property grob 
'staff-position)))
                                     
                                     ;here I would probably do a call to 
ly:stencil-translate-axis
                                     ;or possibly change the grob's values and 
re-calculate the 
                                     ;stencil, but i'm unsure if the latter is 
possible
                                     
                                     (pretty-print y-offs) 
                                     (pretty-print staff-pos)
                                     ))

{ \override Staff.Rest.after-line-breaking = #move-rest-after-line-breaking r2 
  << { r4 f''4}
     \\
     { e'4 r4 } >> 
}
