Any help is greatly appreciated here. There's another approach to the SVG output problem: You can take PDF or EPS output from lilypond, and try to turn it into SVG files. The postscript backend of lilypond is obviously more mature, and there exist converters from pdf/ps to svg. Free converters are a bit shaky, but for some lily versions I managed to convert .ly files into valid SVG via a chain of converters. Usually, you need to first expand fonts to curves using some ps2ps-like script, and then use pstoedit to convert to something that can be converted to svg. Unfortunately, most conversion tools are rather immature, so you will need some experimenting to make it work. IIRC, I managed to generate valid svg with this method for my master's thesis, using a lilypond version around 2.6. I don't remember the exact combination of commands that worked though. (I have vague memories that it may be good to start with pdf output and convert it back to eps) Here's a script that works for some subsets of ps (not lily's though), you can look at it for ideas: http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Electronics/Ps2svg.sh If you manage to find a fairly reliable path to convert the output of a recent lily version into wikipedia-usable SVGs, I'd be happy to know.

Re: Fonts in SVG output
Hi, I thought I ought to follow up what Nick has said with a little explanation of what I have done. (This is probably more appropriate to the lilypond-devel list but, since the discussion was started on *-user, I am following up here). I should also point out that I am not a C/Guile/Scheme expert so there may be a much easier way to do the following. I have a database with music and performance data in it. I need to create a score and display performance data above each note in the score. I have written a Python script which creates a *.ly file from a query to the database. Each line in the file contains just 1 note with a comment at the end which contains the note ID number (which is unique to each note in the database). The file is processed by a slightly hacked version of lilypond to produce an *.svg file. I changed the interpret_stencil_expression function, in the ./lily/stencil-interpret.cc C file, after the head == ly_symbol2scm (grob-cause) line. (If I understand correctly, the grob-cause function is called once to create the links to source file lines in the pdf output). It now calls grob-cause with an extra begin parameter, followed by calling itself, followed by grob-cause with an end parameter. I changed the grob-cause function in the ./scm/output-svg.scm scheme file to create a link to the originating line in the *.ly file on each notehead. It creates an opening tag the first time it is called and a closing tag the second time. I then process the *.svg file to follow each link to the *.ly file and read the originating note ID number from the comment at the end of the line. I can then use the ID to access relevant data in the database and display it above the notehead. There are several problems with this approach: The hacks break support for any other output other than SVG. - Solution: I keep the hacked version in its own source tree and link to it using the --relocate option. The output could be made more informative by adding more/different data to the svg output. For example, so that an SVG line says I am a ledger line or I am a note stem. I hope to implement this in the not too distant future. I'll keep the list posted. No SVG viewers that I am aware of support multiple pages. - Solution: An XSL transform or simple Python script could extract the pages from the SVG output. I just haven't got around to this yet. No SVG viewers that I am aware of actually use the font descriptions in the lilypond SVG output - they rely on the correct font being available in the system font directory. Inkscape and rsvg-view (part of librsvg on most GNU-Linux distros) seem to be the most reliable for displaying lilypond SVG output. I have had some problems with SVGs and fonts. It seems to work OK if I use the same version of lilypond for hacking and normal use and have copies of the fonts in my ~/.fonts directory (GNU-Linux). If anyone is interested in my hacks I would be happy to provide code/patches. Stuart ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user

Cheers, - Graham We are very interested in SVG output, and we're working on it, but with only very limited resources I'm afraid. The reason we're interested is that we see it as an excellent vehicle for enabling Lilypond to be used as a typesetting engine in database queries. We're wanting to produce excellent quality scores automatically and typeset additional information which arises as the result of, for example, performance information stored in a database. Stuart Pullinger made a quick hack of the scheme and there's a brief demo of what might be done here: http://markov.music.gla.ac.uk/Click-Chopin Not much yet, but much much better than nothing. We also had font issues, so the SVG gets converted to PNG server-side. Stuart's wiki page: http://markov.music.gla.ac.uk/cmt-wiki/StuartPullinger I can't offer a bounty per se, but if any UK national with a 1st class or upper second in a numerate discipline seriously wants to work on this for three or four years, we might be able to fund a PhD studentship (£12600p.a. tax free if memory serves, no council tax to pay). email me.

Re: Fonts in SVG output
It is little difficult for me. I have in directory ~/.fonts no fonts. There is only any file named fonts.dir. Is it necessary copy fonts into this directory from other one? Will Inscape prefer fonts from this directory? Sorry, I don't use linux (yet ;-). I guess ~/fonts is where linux stores the font files, but I don't know exactly what it is. In windows this is a folder named c:\windows\fonts. I have all the lilypond otf font files here and inkscape just finds them there. I don't know how inkscape finds the fonts under linux, or how to configure it. Perhaps some linux user can tell you more about that.

Re: Fonts in SVG output
Make sure the fonts you have in ~/.fonts are exactly the same employed by the lilypond version you are using to the generate the svg file. I've had the same problem before and I've found that the fonts vary quite often from one version to the next (at least in the development brach). I replace the fonts each time I upgrade the lilypond version and then I recreate the svg file again. This works for me (except the aybabtu font). For the time signature and bar numbers, lilypond seems to insist in using the feta font when it renders the svg file, but (I guess) it should use Emmentaler. Because the feta font doesn't exist for Inkscape, it uses the default font.
