RE: Octave checks, relative, and spurious warnings ...

[Anthony Youngman]

Sounds good.

I'm trying to test it to see if it works for me, but (running in mingw,
W2K) when I add it into my files lily just seems to crash - I don't get
the cmd.exe window appear, or I get loads of complaints in the log file.

I guess I'm doing something silly, but I'd say this is a worthwhile
addition if it does what I think it does.

Cheers,
Wol

does this help?

I wrote it for Darius a while back, but maybe we should add it to the 
standard .ly include ?


resetOctave  =
#(def-music-function
    (parser location reference-note)
    (ly:music?)

   (let*
    ((notes (ly:music-property reference-note 'elements))
     (pitch (ly:music-property (car notes) 'pitch))

   )

    (set! (ly:music-property reference-note 'elements) '())
    (set! (ly:music-property reference-note
       'to-relative-callback)
       (lambda (music last-pitch)
        pitch))

    reference-note
    ))


\relative c' {
   c d e
   \resetOctave c''
   b
}
