Hi Dean, I know I struggled with this when I did it with Spirit + Phoenix, I don't know how Spirit 2 is different. The only way I could find was to keep a buffer variable containing the possible user info, and then commit to it once an @ was found.
See my confusion in action here: http://cpp-netlib.svn.sourceforge.net/viewvc/cpp-netlib/branches/uri/boost/network/uri.hpp?revision=143&view=markup I don't know if that helps at all, but maybe you can find inspiration somehow... It looks like the Spirit 2 grammar has an entirely different form, so I don't really see how it ties into the Spirit 1 model.
