Dear developer,
With examples and tutorials found around the web i am managing to get some
programming done in scheme for lilypond with one exception: I can't get the
properties function to work and i can't see why. All scheme programming seems
to
work fine, as long as i'm not using properties. So this example works fine:
-- begin file --
#(define-markup-command (double-box layout props text) (markup?)
"Draw a double box around text."
(interpret-markup layout props
(markup #:override '(box-padding . 0.4) #:box
#:override '(box-padding . 0.6) #:box text)))
\markup \double-box A
-- end file --
But this example generates an error:
-- begin file --
#(define-markup-command (double-box layout props text) (markup?)
#:properties ((inter-box-padding 0.4)
(box-padding 0.6))
"Draw a double box around text."
(interpret-markup layout props
(markup #:override `(box-padding . ,inter-box-padding) #:box
#:override `(box-padding . ,box-padding) #:box text)))
\markup \double-box A
\markup \override #'(inter-box-padding . 0.8) \double-box A
\markup \override #'(box-padding . 1.0) \double-box A
-- end file --
The error reported is: "Unbound variable: inter-box-padding"
I'm using windows 7 64 bit, lilypond 2.12.3
I hope you can tell me what i'm doing wrong
Best Regard, Tim
