Hi list !
I'm training some Scheme stuff, especially by rewriting basic Lily
functions in Scheme. I'm now trying to create a function that increases
by 1 the degree of the note argument. So I have to "catch" the second
figure of the
'pitch
(ly:make-pitch a b c))
to add 1 to it.
The function begins with :
increasedegree= #(define-music-function (parser location note)(ly:music?)
"adds 1 to the second figure of the pitch"
(let ((result-note (ly:music-deep-copy note))) ;local copy
of the note passed as argument
((result-pitch (ly:music-property (first
(ly:music-property result-note 'elements))
'pitch))) ;local copy of the pitch of result-note
How can I call for the second figure of the pitch?
This trick would be usefull for other functions I'm trying to write !
Maybe this trick is treated in the manual, but I haven't seen it...
have a good day !
JMarc
