The new release of xpressive is available now. It represents a complete rewrite of all of xpressive's meta-programming. This is an important milestone on the way to 1.0. I encourage anybody who has been using xpressive to grab the latest version and let me know of any problems.
Looks nice! Could it be possible to write up a small template framework to create scanners for spirit with xpressive? I could love a syntax like: template<typename IteratorT> struct my_scanner<IteratorT> : public boost::xpressive<my_scanner<IteratorT> > { struct result_type : public boost::xpressive_variant<string, int, pair<IteratorT,IteratorT> > {}; enum token_type { number, literal }; struct scanner_definition { scanner_definition() { //pseudocode: matcher<string,literal> = as_xpr('"') >> _ >> '"'; matcher<int,number> = range('0', '9'); // ... } }; }; Another thing: I always thought one should not use identifier names starting with an underscore like: "_b"?
