here is a simplified version of the problem and the lilypond error:
hpRot = #(define-music-function (parser location rot) (list?)
#{
\once \override Hairpin #'rotation = $rot
#})
fooBar = #(define-music-function (parser location zabadoo) (number?)
#{
{ a b c d \hpRot #'($zabadoo 0 1) s2^\< s s s \! }
#})
\fooBar #3
Drawing systems.../usr/share/lilypond/2.12.2/scm/layout-page-layout.scm:53:9:
In
procedure ly:system-print in expression (ly:system-print sys):
/usr/share/lilypond/2.12.2/scm/layout-page-layout.scm:53:9: Wrong type
(expecting real number): lilyvartmpc
from what i can guess the variable is not being evaluated but instead being
passed as lilyvartmpc ...
thanks
