I am once more experimenting with ly:book-process. The background is
that I have managed to generate my complete score within a Scheme
function, but now I need the function to produce more than just one
\score (namely an alternation between multiple scores and top-level
markups).
But it seems somewhat unpredictable how the \paper and \layout blocks
behave.
In the following example the \paper block is not respected while the
\layout block is:
\version "2.19.45"
engrave =
#(define-void-function ()()
(let*
((book
#{
\book {
\markup "Movement title (to be generated)"
\score {
\new Staff { c' d' }
}
}
#}))
(ly:book-process
book
#{
\paper {
indent = 0\cm
}
#}
#{
\layout {
\context {
\Score {
\override NoteHead.color = #blue
}
}
}
#}
(ly:parser-output-name (*parser*)))))
\engrave
However, in my actual file the \layout block isn't respected either.
I can't give more details about the latter issue right now, but if I get
the first issue sorted out (which works with the MWE) I might get an
idea to get a step further with that.
Thanks for any hints
Urs
