The conclusion of [1], on how to put nicely cropped png or svg images
into individual files with specified file names, was to wrap each score
in a \book block with an individual \bookOutputName, as shown in that
message.
Since I have 1000+ such scores, each conveniently created by a scheme
function, it should be easy to just add the book wrapper inside that
function. The first step was beginning like this MWE:
\version "2.24.1"
scr =
#(define-scheme-function (mus) (ly:music?)
#{
%\book {
\score { #mus }
%}
#} )
\scr { c'' }
But un-commenting the two lines above generates "error: bad expression
type".
Adding -lDEBUG didn't explain more. Does that error mean \book is
forbidden here?
How can I include a \book wrapper (and \bookOutputName) in my score
function?
Yeah... there are known syntax quirks in that area. This works though:
|\version "2.24.1" scr = #(define-void-function (mus) (ly:music?)
(print-book-with-defaults #{ \book { \score { #mus } } #})) \scr { c'' }|
Thanks, Jean! I never would have guessed. I'll give it a try.
