LILYPOND->MUSICXML GSOC 2015 PROJECT Written by David Garfinkle HOWTO: Run lilypond scheme-sandbox Load lily-env.scm from gsoc/ directory Call (music->xml mus) from gsoc/ directory on a music expression mus Currently limited to single-voice SequentialMusic contexts of notes, chords, articulations (not all are supported, such as early-music or instrument-specific examples), key signatures, time signatures, and clefs INCLUDED EXAMPLES: samples/lilysamples.scm has lazy examples of music expressions. 3 good examples are "hw" , "chords" , "articulations" ; here is how to run them: lilypond scheme-sandbox (load "lily-env.scm") (define hello-world (force hw)) (music->xml hello-world) Result will be stored in musicxml.xml WHAT'S GOING ON UNDER THE HOOD 1. (run-translator) ; lily/lily-time.scm ; pre-procecesses music expression mus, inserting measure information as a guile object 2. (music->sxml) ; lily/make-sxml.scm ; transforms music expression mus into its SXML equivalent. It's modelled after music->make-music in lily function \displayMusic 3. The output from (music->sxml) is written to sxml-transfer.scm so it can be transfered into a guile2.0 script 4. (lily-sxml->music-sxml) ; guile2.0/sxml_conversion/sxml-conversion.scm ; takes the lily-sxml written in sxml-transfer.scm and translates it to a music-SXML representation 5. (sxml->xml) ; uses (sxml simple) guile module to convert the music-SXML to an XML equivalent TODO LIST guile2.0/sxml_conversion/data-types.scm: --the way measures are stored is a huge mess. i should make it explicit tree structures or a-lists --insert measures according to increasing order, so as to keep the list of measures sorted guile2.0/sxml_conversion/sxml-conversion.scm: lily-sxml->music-sxml --edit the matching functions so that they match list permutations (not sure if this is possible) or at least find an alternative to listing each list permutation as a new match. ex: [(list (val ,val) (symbol ,symbol)) (action-expression)] but also requires [(list (symbol ,symbol) (val ,val)) (action-expression)] since the music expressions aren't consistent one way or another lily/make-sxml.scm: (make-sxml.scm) --Remove the unncessary list containers, then edit sxml-conversion.scm so it doesn't have to match lists of lists --format the output so it's indented and looks pretty for better testing lily/lily-time.scm: (run-translator) Include moment information so that we can process SimultaneousMusic. The problem is trying to read the moment information back into Guile2.0... #<Mom 0> throws an error?! lily-env.scm: (music->xml)) --Provide a switch to choose output file-name, or to define a new object with the xml rather than output --delete sxml_transfer.scm when you're done with it? --somehow pass the scheme object from the lily script to the guile2.0 script without having to write a new file? guile2.0/sxml-to-xml.guile --remove the backslash in \" , and remove \n and \t when printing the XML header, also remove the wrapping quotes in the XML header.
