Hello list,
in another thread, my problems with command line arguments were
solved (or workarounds provided), but now I am stuck with
another but similar problem:
I want to transpose some music and tell lilypond the 'to' pitch
in the command line:
lilypond -dpitch="e'" myfile.ly
where myfile.ly is
\version "2.15.24"
optionalTranspose = #(define-music-function (parser location music)
(ly:music?)
(let ((mypitch (ly:get-option 'pitch)))
#{ \transpose c $mypitch $music #}))
melody = { c'4 d' e'2 }
\score {
\new Staff {
\new Voice { \optionalTranspose \melody }
}
}
Lilypond refuses to see mypitch as a pitch. I tried to convert it
with (ly:music-property mypitch 'pitch), but lilypond soesn't take
the command line argument as a music expression, too.
Is there any chance to convince lilypond to accept a pitch on
the command line?
Thanks in advance,
Marc
