musicxml2ly makes an apparently defective lilypond file

Patrick Karl Wed, 14 Dec 2016 09:37:53 -0800

So, I have the following lilypond file, named test.ly:

\version "2.19.46"
music = { c'' }
\score {
  \new Staff \music
  \layout { }
  \midi { }
}


I compile it so:  lilypond test.ly

which generates a pdf file and a midi file.

I open the midi file in Musescore 2.0.3.1 and export an xml file, named test_midi_Musescore.xml

I run musicxml2ly test_midi_Musescore.xml, which generates a lilypond file named test_midi_Musescore.ly.



There seem to be two problems with the output of musicxml2ly:

  *  file test_midi_Musescore.ly produces: test_midi_Musescore.ly: data

It should probably produce: test_midi_Musescore.ly: ASCII text. Another indication that something is aglee with test_midi_Musescore.ly is the output of "more test_midi_Musescore.ly", namely: "test_midi_Musescore.ly" may be a binary file. See it anyway?



  *  lilypond is unable to compile test_midi_Musescore.ly.  It fails with


pat$ lilypond test_midi_Musescore.ly
GNU LilyPond 2.19.46
Processing `test_midi_Musescore.ly'
Parsing...
test_midi_Musescore.ly:6:25: error: EOF found inside string
    encodingsoftware =

test_midi_Musescore.ly:6:25: error: syntax error, unexpected end of input, expecting \header

    encodingsoftware =
                        "
fatal error: failed files: "test_midi_Musescore.ly"

I am attaching test.midi, test_midi_Musescore.ly and test_midi_Musescore.xml.



Is there a workaround?  Is this a bug?
