alignment-offsets has been replaced with alignment-distances and the
semantics have changed too: alignment-distances gives the distances
between staves (but not Lyrics or other loosely spaced lines) so its
length should be one less than the number of staves. Also, you can set a
forced distance of 23 for any of the xxx-spacing variables with

xxx-spacing = #'((space . 23)  (minimum-distance . 23) (stretchability .
0))

Let me know if there is functionality that you can't achieve with these
settings.

Excellent.

So the 2.13.x version of the snippet included earlier in the thread looks like this:


%%% BEGIN STRICT STAFF POSITIONING 2.13.x %%%

\version "2.13.9"

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

%%% END STRICT STAFF POSITIONING 2.13 %%%


(Resulting PDF attached.)

Thanks very much for this. And FWIW I find distances considerably better than offsets. It takes concentration to remember that the values of the (old) alignment-offsets alist need to be *negative* numbers. Much better that the (new) alignment-distances alist values are absolute.

And, as of now, I'm unaware of any spacing functionality that's gone missing in recent dev releases.

Thanks again.

Trevor.
