Thanks for helping me out. I've attached some examples of what I am
working with so far.
The ANSIAsuccessful files have the code that works correctly (minus
all of the vertical collision, which I can deal with). What it shows
best is that there is one system per page and the systems vertically
fill the pages.
The ANSICunccessful files show that there are multiple systems per
page with and the systems are all bunched together.
The finishedexample pdf shows what I have been able to achieve in the
past using the ANSI A page size. I am moving to ANSI C page size for
better spacing in general.
I hope all of this makes sense.
OK, I've opened a bug report about this:
https://gitlab.com/lilypond/lilypond/-/issues/6407
And I suggest a completely different solution to center the systems,
sidestepping the issue:
\version "2.22.2"
\paper {
ragged-right = ##t
indent = 0
short-indent = 0
}
\layout {
\context {
\Score
%% Can't use a callback for line-break-system-details because it is
sometimes
%% read before line breaking, for alignment-distances. Even
after-line-breaking
%% can be too early for the System's X-extent due to things like
system start
%% delimiters which trigger page layout prematurely.
\override NonMusicalPaperColumn.stencil =
#(lambda (grob)
(let* ((sys (ly:grob-system grob))
(ext (ly:grob-extent sys sys X))
(len (interval-length ext))
(layout (ly:grob-layout grob))
(width (ly:output-def-lookup layout 'paper-width))
(left-margin (ly:output-def-lookup layout 'left-margin))
(off (- (* 1/2 (- width len))
left-margin))
(det (ly:grob-property grob 'line-break-system-details)))
(ly:grob-set-property! grob
'line-break-system-details
(acons 'extra-offset
(cons off 0)
det)))
#f)
}
}
{
#@(map (lambda (i)
#{ \repeat unfold #i { c'1 \noBreak } \break #})
(cdr (iota 15)))
}
I tested it on the score you sent me privately and it seems to work.
Best,
Jean

I did set the paper size in the paper block using
#(set-paper-size "ansi c" 'landscape )
The only difference between previous, successful uses of this script
and now is that I am using the ansi c page size instead of ansi a.
I don't see a problem on this example:
\version "2.23.12"
\paper {
ragged-right = ##t
}
\paper {
#(set-paper-size "ansi c" 'landscape)
}
#(define-markup-list-command (center-column-list-args layout props args)
(markup-list?)
#:properties ((baseline-skip))
(let ((stils (interpret-markup-list layout props args))
(line-width (ly:output-def-lookup layout 'line-width)))
(space-lines baseline-skip
(map
(lambda (arg)
(ly:stencil-translate-axis
arg
(/ (- line-width (interval-length (ly:stencil-extent arg X))) 2)
X))
stils
\markuplist \center-column-list-args \score-lines {
\repeat unfold 100 { c'1 \break }
}
The issue must be somewhere else. Please post a minimal working example
so that we can diagnose the problem. See
https://lilypond.org/tiny-examples.html
about how to create it.
By the way, this snippet can be simplified a lot:
\version "2.22.2"
#(define-markup-command (page-center layout props arg) (markup?)
(interpret-markup layout props #{ \markup \fill-line { #arg } #}))
\markuplist
%\override #'(baseline-skip . 20)
\column-lines \page-center \score-lines {
\repeat unfold 100 { c'1 \break }
\layout { ragged-right = ##t }
}
Best,
Jean
