A voicename not is recognised in a music function.
In the example below, I'd expect to get two documents with the same
content. However, in the error document, no lyrics are typeset, and
an error is sent into the logfile. Why?
\score {
\new Voice = melody { \relative c'' { d cis b a } }
\new Lyrics \lyricsto melody \lyricmode { An ex
-- am -- ple. }
}
vs.
MusFunc = #(define-music-function (parser location) ()
#{
\new Voice = melody { \relative c'' { d cis b a } }
\new Lyrics \lyricsto melody \lyricmode { An ex -- am --
ple. }
#} )
\book {
\bookOutputSuffix Error
\score {
\MusFunc
}
Music functions return sequential music by default, not a sequence of
partial music expressions folded into an upper syntactical construct.
So the lower is the equivalent of
\score {
{
\new Voice = melody { \relative c'' { d cis b a } }
\new Lyrics \lyricsto melody \lyricmode { An ex
-- am -- ple. }
}
}
if I am not mistaken.
It is likely that you can return a parallel music expression explicitly
using Scheme.
Perhaps it would be nice to allow # instead of #{ as a shortcut for
creating a music expression returning parallel music.
