I consider it much nicer to make "strg" of type fraction?, and then num
can be (car strg) and denom can be (cdr strg).
and
can just be \spreadTimeSignature #8 2/4 ... which is nicer on the eyes.
I was intrigued and tried to modify the code as you suggested as a learning
exercise. But I ran into a problem I do not understand. I assumed that fraction
is a pair of two numbers, so num and denom are of type number. "column" needs
strings so the numbers have to be converted. However, I get the following
error:
test12.ly:18:25: error: syntax error, unexpected NUMBER_IDENTIFIER
(number->string
$num)
/usr/local/lilypond/usr/share/lilypond/current/ly/init.ly:61:0: error: error in
#{ ... #}
I think I'm close but missing some subtle issue about the types.
