I don't think you can use stdout itself, as LP already uses it. However, you can use a pipe: $ mkfifo foo.svg $ lilypond -dbackend=svg -o foo music.ly which will block until you, say, $ cat foo.svg | some-consumer-of-svg I haven't tested whether LP *insists* on adding an .svg extension. > Some background: I am developing an online course in Open edX [1], and > for that course I am writing an XBlock [2].

Or better alternatives? Cheers, David.
