Hello,
is it possible to have a Scheme function output a bookpart? In the
attached
example and my real-world setup, I get ‘error: bad expression type’.
TIA, Simon
Hi Simon,
this may give you a starting point:
\version "2.19.27"
test =
#(define-scheme-function (mus) (ly:music?)
(ly:book-process
(ly:make-book-part (list (ly:make-score mus)))
$defaultpaper
$defaultlayout
(ly:parser-output-name)))
m = { c'4 }
\test \m
Shoot, I did find a flaw: I need a \bookpart {}, not a \book, but it
needs to contain a \paper block. How can I do that?
What a joy: by accident I found in scm/lily-library.scm that for which I
was looking. It’s the scheme procedure collect-bookpart-for-book, with
which I could compile the following function to complete my framework
for a project:
%%%%%%%%%%%%
bookpartBox =
#(define-scheme-function (parser location roman) (symbol?)
(collect-bookpart-for-book
#{
\bookpart {
\paper {
system-count = $(assoc-get roman system-count-alist)
systems-per-page = 4
}
\scoreBox
}
#}))
%%%%%%%%%%%%
Yours, Simon
