Ok, I was too optimistic. Could anyone help me out here, I do not
understand what's wrong here:
\version "2.17.14"
% this is intended to return an alist with the given values:
make-spacing = #(define-scheme-function
(parser location bdist mdist padd stret)
(number? number? number? number?)
'((basic-distance . bdist)
(minimum-distance . mdist)
(padding . padd)
(stretchability . stret))
)
\paper {
#(display (make-spacing 60 2 3 4))
system-system-spacing = #(make-spacing 60 2 3 4)
#(display system-system-spacing)
}
% error message: Wrong type to apply: #<Music function #<procedure #f
(parser location bdist mdist padd stret)>>
Cheers,
Joram
