Hi all, The Spirit team proudly announces that we committed Spirit V2.1 (beta) to the Boost SVN (trunk). We will continue the development there, so please don't use the Spirit SVN anymore as it will quickly go out of sync. Spirit V2.1 is a complete rewrite of V2.0, while maintaining most of the V2 interface. We will add a comprehensive document explaining what's changed soon. Here are some of the highlights: - More homogeneous interface (multi-attribute API similar to printf/scanf, but using Qi/Karma format descriptions) - More balanced set of primitives and directives (Qi and Karma now better complement each other) - Reduced compile times! Compilation is up to 50% faster if compared to equivalent code from V2. - Optimized execution times. Spirit is now faster than ever before. - Simplified usage of grammars and token definitions - Fixed a whole bunch of bugs and inconsistencies - etc. Please report any experience you might gain (good and bad)! As a side note: Joel and I will give a talk about Spirit V2.1 at BoostCon in Aspen slightly more than a week from now. You still can register (www.boostcon.com) if you haven't done yet. On behalf of the Spirit team Regards Hartmut PS: We would like to thank all who participated and contributed to this. It really was a major team work!
