I am not sure if the MusicXML effort such as implemented by Python-ly (and used in Frescobaldi) really can compete with an in-LilyPond solution. Frescobaldi (and also the ly command provided by the python-ly[1] package), currently understands LilyPond music (i.e. music written in LilyPond syntax, not built by Scheme functions) and is able to export that to MusicXML. [1] https://github.com/wbsoft/python-ly We do this by having our own LilyPond parser (that also powers the syntax highlighting in Frescobaldi) and building a tree-structured music expression from it and Peter Bjuhr added code to build a MusicXML document from that music structure, which works quite well. We are extending this to a route where LilyPond itself parses the file and builds the score, music expressions etc, and converts this to a "LilyXML" document[2]. We can then read the XML in a python module and convert it to MusicXML. But we still only use the music input expression, not any output of the layout and engraving process. This is in development. [2] https://github.com/wbsoft/python-ly/blob/master/ly/xml/xml-export.ily see also http://python-ly.readthedocs.org/en/latest/ly.xml.html#the-xml-export-ily-file However, the effort described on the LilyPond Google Summer of Code page goes much further: it not only builds the basic XML document but also adds the layout information created by the engraving process, which is much more advanced, as it takes advantage of LilyPond's excellent layout. So I think people should not hesitate to build an excellent MusicXML exporting function in Lilypond, as the python-ly/Frescobaldi effort will not be able to use the layout information from LilyPond, but just the music (like the Midi output, but in a more advanced way of course) Wilbert -- Wilbert Berendsen (http://www.wilbertberendsen.nl) _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
