VerticalAxisGroup #'next-staff-spacing controls the spacing between two
staves in the same system. For spacing between systems, use the
between-system-spacing variable in the \paper block.

Hi Joe,

What about the NonMusicalPaperColumn alignment-offsets list? I put together NR (2.12) 4.3.3 'Explicit staff and system positioning' some time back, mostly as a way of documenting a type of absolute vertical positioning layout that I've used in all of my scores since then. As of 2.13.ish this seemed to stop working. Quick example:


%%% BEGIN EXPLICIT VERTICAL POSITIONING SNIPPET %%%

\version "2.13.9"
%\version "2.12.2"
\include "english.ly"

\new StaffGroup <<
   \new Staff {
      \overrideProperty #"Score.NonMusicalPaperColumn"
      #'line-break-system-details
      #'((Y-offset . 0) (alignment-offsets . (0, -10)))
      c'1 \break
      \overrideProperty #"Score.NonMusicalPaperColumn"
      #'line-break-system-details
      #'((Y-offset . 40) (alignment-offsets . (0, -15)))
      c'1 \break
      \overrideProperty #"Score.NonMusicalPaperColumn"
      #'line-break-system-details
      #'((Y-offset . 80) (alignment-offsets . (0, -20)))
      c'1 \break
      \overrideProperty #"Score.NonMusicalPaperColumn"
      #'line-break-system-details
      #'((Y-offset . 120) (alignment-offsets . (0, -25)))
      c'1 \break
   }
   \new Staff {
      \clef bass
      c'1 c'1 c'1 c'1
   }
>>

%%% END EXPLICIT VERTICAL POSITIONING SNIPPET %%%



The two PDFs attached here show alignment-offsets doing what I would expect in 2.12.2 but no in 2.13.9.

I'm excited about the array of new paper-block settings in the 2.13.x series. Also it is crucial for me to be able to specify absolute staff positions on the page via some mechanism. Will such a thing continue to be possible? (Or maybe it already is with the correct combination of new settings?)

Thanks!

Trevor (B.)
