Boost C++ Libraries: Ticket #6213: Escaping close parentheses doesn't work in boost::regex

Steven Watanabe — Mon, 05 Dec 2011 17:11:39 GMT

It seems to work with MSVC 10 with the trunk:

#include <string>
#include <boost/regex.hpp>
void f(const std::string& val)
{
    boost::regex expr1("(.*)\\((.*)\\)");
    boost::cmatch matches;
    if(boost::regex_match(val.c_str(), matches, expr1))
    {
        std::cout << "matched" << std::endl;
    }
}
int main () {
    f("test(test)");
}

I don't see any obvious recent changes that would affect this. Do you have an example string that fails to match?

As Steven says, we need to see the string that failed to match to tell you what's going on. My suspicion is that the string has content after the closing ")" in which case regex_match will fail (remember regex match only succeeds if the whole of the text was matched).
