Re: Lilypond's SVG output
Hello, 2011/8/18 Sandor Spruit a.g.l.spr...@uu.nl Hello, I recently had an informal discussion with some collegues on the use of SVG, in general. They are in music research, I am a developer working on a completely unrelated topic - so please forgive me my ignorance w.r.t. music-related terminology. We discussed the possibilities to use music scores on web pages, and they immediately referred to Lilypond because of its quality output. While browsing this list's archives, and other on-line discussions for that matter, two questions came up: - In what version, exactly, did Lilypond drop the use of groups (svg:g) in its output? I read a debate on this issue, where the key argument against groups was the trouble people have in editing grouped SVG elements in Inkscape. I can, however, imagine all sorts of situations in which group elements could be very useful - from a developer's point of view at least. This leads to the second question: - For what purpose are people putting music up on the web; what's the typical use case? Just publishing it for others to read? Hyperlinking to it, from it? Annotations? Keeping bits and pieces of music for later reference? Learning? Studying? Comparing versions? I may, at some point, be in the position to do some work on this. But I'm hesitant to dive in at the deep end - meaning Lilypond tens of thousands of lines of code ... A bit of guidance might help though :) cheers, Sandor Spruit Information and Computing Sciences, Utrecht University __**_ lilypond-user mailing list lilypond-u...@gnu.org https://lists.gnu.org/mailman/**listinfo/lilypond-userhttps://lists.gnu.org/mailman/listinfo/lilypond-user I can not answer your questions, but maybe developers list is better place to ask... forwarding.

LilyPond still uses groups. grep g in scm/output-svg.scm. OK, thanks. I stand corrected. Let me rephase my comment. When looking at the very nice example Tim Sawyer (percussion360.com) posted on the user list this afternoon, I think the use of svg:g needs a bit of work to enable that sort of app. I read a debate on this issue, where the key argument against groups was the trouble people have in editing grouped SVG elements in Inkscape. I can, however, imagine all sorts of situations in which group elements could be very useful - from a developer's point of view at least. This leads to the second question: - For what purpose are people putting music up on the web; what's the typical use case? Check the list archives for an e-mail from Michael Geary. He's working on this. I do it too for my musical compositions (http://www.apollinemike.com/norman1). OK. I think I've found the mail you're referring too. Just publishing it for others to read? Hyperlinking to it, from it? Annotations? Keeping bits and pieces of music for later reference? Learning? Studying? Comparing versions? There is no formal hub that groups these efforts together, but as the SVG standard becomes better supported by more and more browsers, I'm sure it'll get picked up by more and mor epeople. There's a number of additional comments on the list that I missed the first time round. I may, at some point, be in the position to do some work on this. But I'm hesitant to dive in at the deep end - meaning Lilypond tens of thousands of lines of code ... You don't need to jump into tens and thousands of lines of LilyPond code - all of the svg backend is present in output-svg.scm. Michael Geary is likely to be sponsoring some work on this too - I'll keep you posted if/when this happens. Well, I do feel I need to have some insight into the inner workings of Lilypond before I can do anything meaningfull here, i.e. more than just the backend. A solution enabling a more general use of the features Tim demonstrates may be use in research too, so maybe I can work on this during office hours... cheers, Sandor ___ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
