Hi, I'm having a lot of trouble with boost::regexp and locales, even trying to change it makes the program fail.
Can anybody help?
#include <iostream>
#include <string>
#include <cstdlib>
#include <cassert>
#include <vector>
#include <stdexcept>
#include <locale>
#include
using namespace std;
using namespace boost;
int main(int argc, char *argv[]) {
string regexp, text;
if( argc != 3 ) {
exit(EXIT_FAILURE);
} else {
regexp = argv[1];
text = argv[2];
}
cout << "regexp: " << regexp << endl;
cout << "text: " << text << endl;
regex re(regexp,regex_constants::perl);
re.imbue(locale("es_ES.UTF-8"));
smatch match;
if(regex_match(text, match, re)) {
cout << "MATCH" << endl;
for(smatch::const_iterator i = match.begin(); i != match.end(); ++i) {
cout << i->str() << endl;
}
} else {
cout << "NO match" << endl;
}
}
./testre '\w' "é"
