I need a free/GPL stuff. The two main options that come to mind are: boost::regex: http://www.boost.org/libs/regex/doc/index.html pcre: http://www.pcre.org/ Libraries such as Qt or (the dev version of) wxWindows also include a regular expressions engine.

I need a free/GPL stuff. Certainly. Check out these: Boost.Regex http://boost.org/libs/regex Widely used, well tested, efficient, good STL integration. Forms the basis for the current proposal to add regular expressions to the Standard Library. Totally free. GRETA http://research.microsoft.com/projects/greta Fast, highly perl compliant, good STL integration. Free for commercial use (if you get it via the PowerTools download at http://www.gotdotnet.com/team/cplusplus/) PCRE (Perl Compatible Regular Expressions) http://www.pcre.org/ Excellent perl compliance. No STL integration. Free for commercial use. And if you're feeling adventurous... xpressive Available via CVS in the boost-sandbox (http://sourceforge.net/projects/boost-sandbox/) Similar to Boost.Regex, except that regular expressions can be written either as strings or as expression templates (for improved performance and syntax-checking at compile time). Currently in beta. Totally free. (Full disclosure: I wrote GRETA and am actively developing xpressive.) -- Eric Niebler Boost Consulting www.boost-consulting.com [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

(it's funny, I've seen acknowledgment in Max Payne 2 that they used boost::regex). thanks to everyone for all the links! It looks like boost::regex is one of your favourites I'll also give a look at GNU regex (the last release is date 1993!) actually I need a library to implement a sort of scanner on the fly, i.e., read a configuration file and scan a file according to regular expressions specified in the configuration file. Do you think using a regular expression library is the right solution? thanks in advance again for any suggestions Lorenzo -- +-----------------------------------------------------+ Quote: Lorenzo Bettini ICQ# lbetto, 16080134 | PhD in Computer Science | Dip.

You definitely need to look at Spirit: spirit.sourceforge.net. interesting tool! but probably that's even too much for what I need to do. I'm the maintainer of GNU source-highlight, http://www.gnu.org/software/src-highlite, that only performs lexical analysis and not parsing. So I need to manipulate regular expressions, more than grammars. At the moment, if you want to add a new language to source-highlight you have to write a flex scanner... now I'd like to provide an easier syntax to define a new language (tokens, operators and so on) and let source-highlight use regular expressions according to the tokens specified.
