Hi all,
(1)
consider the following code (working as expected):
\paper {
#(if #t (set-paper-size "a8" 'landscape) #(set-paper-size "a8"))
}
\score { { R1 } \layout { ragged-right = ##f } }
Switching from #t to #f results in different paper-size, as desired.
(2)
But trying to put it in a procedure, it always returns the true-case:
#(define (proc bool x y)
(if bool x y))
\paper {
#(proc #f (set-paper-size "a8" 'landscape) #(set-paper-size "a8"))
}
\score { { R1 } \layout { ragged-right = ##f } }
Paper-size is always a8-landscape.
(3)
Trying:
#(define (proc bool x y)
(if bool x y))
\paper {
#(apply set-paper-size (proc #t '("a8" 'landscape) '("a8")))
}
\score { { R1 } \layout { ragged-right = ##f } }
Paper-size is always a8
---------
What's happening here and why?
And how to make a procedure accepting set-paper-size work, with
different settings and an if-condition?
Cheers,
Harm
