Friends, there have been some efforts in the past to convert LilyPond music to XML. One of the approaches would be to convert the LilyPond music tree to XML and be able to process it with other tools, which could read the XML and convert it to MusicXML or other XML music formats.
I have now written a script that can be included in a LilyPond file and has functions that can map LilyPond score, music and markup objects etc. to XML, which is written to the current output port (standard output). The script is here[1] and there is some documentation included and also visible here[2]. [1] https://github.com/wbsoft/python-ly/blob/master/ly/xml/xml-export.ily [2] http://python-ly.readthedocs.org/en/latest/ly.xml.html#the-xml-export-ily-file Usage example: \include "/path/to/xml-export.ily" \displayLilyXML { c d e f } The XML closely mimics the LilyPond music structure. Markup objects are also properly converted, as are pitches, durations, moments, stencils, generic scheme lists, strings, numbers, pairs, symbols etc. If you are interested in output the LilyPond music structure in XML format, please test and experiment with this. Note that it is not MusicXML or another XML format, but just the LilyPond music in XML notation. This could be further processed or analyzed with other tools. I am planning to make the XML output as complete and well-structured as possible. In the documentation I describe how the XML is structured. It currently supports \score (and all the music and markup, (even scores inside markup!), but I want to add \book and \bookpart support, and support for \layout, \paper etc. (Reason for writing this was that I am trying to design an intermediate tree-structured storage for parsed LilyPond code in python-ly/Frescobaldi. I decided to look at how LilyPond itself stores the music and to possibly mimic that in the python-ly/Frescobaldi parser.) best wishes, Wilbert Berendsen Frescobaldi and python-ly developer -- Wilbert Berendsen (http://www.wilbertberendsen.nl) _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
