Hi all
Im writing a small sceme function to be able to create examples of
guitar fingerings
for various scales.
basically i create a music function "fretsc" to be called for example as
\fretsc "(6 1) (6 3) (5 0)" to indicate the position and sequence of
notes in a scale.
However I get an "unknown escape string" for \fret while compiling.
Anyone have an idea what Im doing wrong?
Here is the example code if you comment out the last line you can see
the kind of fret diagram I am
working on.
Best regards
Morten Jagd Christensen
\version "2.14.0"
fretsc = #(define-music-function (parser location s1 )
(string?)
#{
\markup{\override #'(fret-diagram-details . (
(finger-code . in-dot)
(number-type . arabic)
(label-dir . -1)
(orientation . landscape)
(dot-radius . 0.5)
(fret-count . 5)
(top-fret-thickness . 5)
(barre-type . straight)
(xo-padding . 0.3) )) {
\fret-diagram-verbose #'(
$s1
)
}
}
#})
ddd = \markup{\override #'(fret-diagram-details . (
(finger-code . in-dot)
(number-type . arabic)
(label-dir . -1)
(orientation . landscape)
(dot-radius . 0.5)
(fret-count . 5)
(top-fret-thickness . 5)
(barre-type . straight)
(xo-padding . 0.3) )) {
\fret-diagram-verbose #'(
(place-fret 5 3 1)
(place-fret 4 5 2)
(place-fret 3 5 3)
(place-fret 2 5 4)
(place-fret 1 3 5)
(place-fret 1 4 6)
)
}
}
\score {
\new Staff {\relative c' { a'^\ddd b c d }}
}
\fretsc "(6 3 1) (5 3 2)"
... and here are the errors:
