Re: [boost] Boost::regex match prefix problem

Typically I would use the following regex - (?<!\\);

Where in c++ it would be something like std::string s("(?<!\\\\);")

Compiles ok but I will get an exception when I try to use it as a parameter to the regex - boost::regex(s)

Lookbehind assertions aren't supported in Boost-1.32, but will be in 1.33. Boost-1.33 should be released soon, but in the mean time, I would suggest you grab a copy of the current Boost-cvs and use that. John.
