Hi there, pretty new to boost::regex and though I'm just toying around
with the documentation and some basic test code. The following code
crashes when setting the BOOST_REGEX_MATCH_EXTRA symbol.
#include <iostream>
#include
void print_captures( const std::string& regx
, const std::string& text
)
{
boost::regex e( regx );
boost::smatch what;
std::cout << "Expression: \"" << regx << "\"\n";
std::cout << "Text: \"" << text << "\"\n";
// crash occurs in the next statement
if( boost::regex_match( text, what, e, boost::match_extra ))
{
unsigned int i,j;
std::cout << "**Match found ** \n Sub-Expressions:\n";
for( i = 0; i < what.size(); ++i )
{
std::cout << " $" << i << " = \"" << what[i] << "\"\n";
}
std::cout << " Captures:\n";
for( i = 0; i < what.size(); ++i )
{
std::cout << " $" << i << " = {";
for( j = 0; j < what.captures(i).size(); ++j )
{
}
}
}
}
int _tmain(int argc, _TCHAR* argv[])
{
print_captures( "(.*)bar|(.*)bah", "abcbar" );
return 0;
}
I'm using MSVC10 express. Am I doing something wrong?
Regards,
Christian
