Comment #11 on issue 3631 by [email protected]: 2.17 does a worse job with
vertical spacing and/or the page layout than 2.16
http://code.google.com/p/lilypond/issues/detail?id=3631
Sorry, I got confused by the definition of the function I copied: it was
called paper-system-staff-extents and returned a pair with the vertical
reference point of first and last system in relation to the stencil. Or
something like that. At any rate, not overly useful information for the
problem.
When I use
#(use-modules (scm paper-system))
\markup
\on-the-fly #(lambda (layout props arg)
(for-each
(lambda (ps)
(format #t "~S\n" (paper-system-extent ps Y)))
(vector->list (ly:paper-score-paper-systems
(ly:score-embedded-format
#{ \score {
\new Voice \repeat unfold 50
{ c,,,4 \repeat unfold 30 r4 c''''''4 \repeat
unfold 30 r4 }
\layout { }
} #} layout))))
empty-stencil) \null
And 2.16.2 against (for convenience's sake) 2.17.30, I get the attached
diff. The differences are quite minuscule (1e-16 and similar should not
make a difference, really). So the box dimensions of the systems do not
seem to be the cause of the difference in results unless I am overlooking
something here.
