How about
convert::to<wstring> convert::to<int, rounding::down> convert::to<wstring, native_mbcs>
I am serious. I actually like it. I understand you do not like my to/from but you are almost there. By eliminating the repetition (as for _string<wstring) we get a laconic and expressive (IMHO of course) interface. No need for various to_string, to_integral, transcode_string, etc. We get rid of the string namespace as well (it should be a plus isn't it?). So, it'd be
int i = boost::convert::to<int>(str); // explicit 'int' type int i = boost::convert::to(str, -1); // deduced 'int' string s = boost::convert::to<string>(-1); // explicit std::string type string s = boost::convert::to(-1, "failed to convert"); // deduced std::string wstring s = boost::convert::to<wstring>(-1); // explicit std::wstring type wstring s = boost::convert::to(-1, L"failed to convert"); // deduced std::wstring
This looks pretty nice to me at first glance. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
