conversion between Boost.Xpressive and Boost.RegEx

I used Boost.Xpressive after 1.3.4, and found it interesting and
helpful, but I suffer from long complie-time. So I wonder there is a
way to write the regular expression in Xpressive and use it in
Boost.RegEx, since there grammer is simmilar to use

If you want to use dynamic regexes with xpressive (the string-based
kind), you can improve compile times by only including all of xpressive
in one file, which has one function in it that accepts a string and
returns a basic_regex<obj ect. Everywhere else, only include the files
that you need for what you're doing, such as basic_regex.hpp ,
match_results.h pp and regex_algorithm .hpp.

HTH,

Hello All, I am a newbie to the Boost library and I have a question about a simple function. All I would like to do is to create a simple function that can test strings using regular expressions. I've written this function which appears to work on the first pass and then fails on the second with the following message.

I hope a Boost question is not too off-topic here. It seems that upgrading to Boost 1.33 broke some old regex code that used to work. I have reduced the problem to this simple example: cout << boost::regex_replace(string("foo"), boost::regex(".*"), string("bar")) << endl; The above code prints "barbar" where I expect "bar". Can anyone shed some light on this? It used to work with 1.30 (though regex_replace

Still learning C++. I'm writing some regex using boost. It works great. Only thing is... this code seems slow to me compared to equivelent Perl and Python. I'm sure I'm doing something incorrect. Any tips? #include <boost/regex.hpp> #include <iostream> // g++ numbers.cpp -o numbers -I/usr/local/include/boost-1_35 /usr/local/lib/libboost_regex-gcc41-mt-s.a // g++ numbers.cpp -o numbers.exe
