Hi folks,
The following code demonstrates the problem I'm having. I'm using Boost 1.33.1 (Debian), but IIRC this worked last year with the same version because I tested it; possibly a Debian-specific regression?
I expect both regular expressions here to match with the value string. They certainly to with egrep. However, I only get the second to match:
% g++ -c regex.cc -o regex.o && g++ -o regex regex.o -lboost_regex % ./regex It didn't match the first It matched the second
Am I correct in my expectation that expression1 will match? If not, what should I be doing to make it match?
Use regex_search. regex_match will only succeed if the expression matches *all* of the string, regex_search will *find* a sub-string that matches. John.
