UNIX Style "Regular Expressions"

[MikeLacey]

Hello all,

At the moment I'm involved in choosing the programming language for a project.

We're choosing between various things, C, C++, Perl, Python, Ruby.

One of the advantages of using something like Perl or Python is the string pattern matching capabilities available in those languages.

So -- My question, after all that waffle:

Is there a C++ library or class that would let us use UNIX Style "Regular Expressions" in a C++ program?

Hello Mike, it may be easier to embed some Perl in your C/C++ project. There is a class available for download from

http://www.codeproject.com

that will enable you to do this. You'll need to have Perl 5.6 or later installed on the machine when compiling (the end user doesn't need to have Perl installed!).

http://www.boost.org

has a good regex library.

I might add that it claims to be faster than grep and supports nearly every type of regex matching you'll find in UNIX (including sed and awk).

Seriously, no C++ programmer should ignore Boost. They're associated with stuff currently in the C++ Standard. Stuff they're doing right now has a high chance of being in the next C++ Standard. Plus they have really awesome stuff. Any serious C++ programmer reading this who hasn't seen Boost: do yourself a favor and go there now.

Thanks for pointing that out chipper! I've just visited boost for the first time and I'll be sure to use a lot of the stuff there.
