You probably have to copy the definition of
print-page-number-check-first from
ly/titling-init.ly into your include file. The reason is probably that
it's defined using
(define ...) instead of (define-public ...) and that your function
definition is
outside the "scope" of the definitions in titling-init.ly (I don't know
any details
on how this works, though).
Hm; maybe it simplifies things a bit to get rid of the include file
and do the example in a single file like this?
%%% BEGIN %%%
\version "2.9.27"
boldNumber = \markup { \fill-line { \bold \fontsize #3 \on-the-fly
#print-page-number-check-first \fromproperty #'page:page-number-string
} }
\paper {
oddFooterMarkup = \boldNumber
}
\new Staff {
c'4
}
%%% END %%%
And here the same parser error arises ...
Parsing...ERROR: Unbound variable: print-page-number-check-first
... which makes me think that maybe there's something going on other
than a scoping error.
Come to think of it, is it even possible to define a substitution for
the righthand side of an assignment like this (where the righthand
side isn't actually a (music) expression but is markup instead)?
I'd love something like ...
boldNumber = "\markup { \fill-line { \bold \fontsize #3 \on-the-fly
#print-page-number-check-first \fromproperty #'page:page-number-string
} }"
\paper {
oddFooterMarkup = \eval boldNumber
}
... but this generates a syntax error:
Parsing...
342.ly:7:0: error: syntax error, unexpected '}', expecting '='
}
