hello boosters,

An old boost library that i was using, provided a validator function (in the value_sematic.hpp file) that could be used for creating user defined parsers and it was handy

The signature was something like : void validator::operator() (any& v, const std::vectorstd::string& xs);

I had a working code that used it and when i tried to recompile my old code with a new boost release it did not compile. I then realized that the validator function is no longer there. Can someone please let me know if this has been substituted by something else (what?) or what i would have to use now in such cases.

It's still there, but in different syntactic form: void validate(boost::any& v, const std::vectorstd::string& xs, YOUR_TYPE_HERE* dummy_parameter, int dummy_parameter2) { // YOUR CODE HERE } The change, as well as dummy parameters, were necessary to handle some broken compilers, notably borland. - Volodya
