When I enter the following reg-ex: "^.*ab+c+d+" for the following text: "aaaabbbcccdddee" the text found is:"aaaabbbcccd". The text found should be: "aaaabbbcccddd". Digging deeper, its seems that the reg-ex function ignores the last character if it is a "+".

This is just using boost::regex_search with the flags = boost::match_any and boost::match_not_null

Am I missing something here?

Yep, match_any says to the regex engine "I don't care what the match is, only if there is one", so it makes certain optimizations that result in the shorter string being found. Stop using the match_any flag and you'll get regular Perl-like behavior. HTH, John.

Hello, I am trying to create a boost::variant from a joint_view sequence of two mpl sequences. Can someone tell me what's wrong in the following example. I can't get this to compile using MSVC 2005. Thanks, Naveen #include <iostream> #include <string> #include <boost/mpl/vector.hpp> #include <boost/mpl/joint_view.hpp> #include <boost/mpl/transform.hpp> #include <boost/variant.hpp> using namespace boost; typedef boost::mpl::vector<int, std::string> t1; typedef boost::mpl::vector<double, char> t2; typedef boost::mpl::joint_view< t1, t2 > mixed; typedef boost::make_variant_over< mixed >::type myTypeTest; void main() { try { myTypeTest t("name"); } catch( std::exception& e) { std::cerr << "Exception caught : " << e.what(); } }
