Dear fellow developers,

I am looking for a good regular expressions handling library. Am
developing an application under Fedora Linux and putting "include
<regex.h>" in my code does not make my compiler complain. I assume
this is the library documented in http://www.opengroup.org/onlinepubs/...s/regex.h.html
document. However I am wondering whether regex.h library is okay, or
would you guys recommend me to use something else (Boost RegEx
libraries for example?)?

Cheers,
Alex

The next version of the C++ standard will include a regex library, and
while I have not checked I am quite sure that it will be based on Boost
RegEx, so going that way will probably ensure forward compatibility.

Don't reinvent the wheel. Linux has powerful methods to allow
processes to communicate effectively. Start a perl program that will
parse text with perl's regular expressions, and then read its output
from your C++ program. With a little effort you get your solution and
bonus of parallelized and syncronized processes of parsing text (perl
program) and handling parsing results (C++ program).

There are two good open source regex libraries. For C++
the boost regex library is probably as good as it gets.

If you want an older UNIX C-style regex Henry Spencer
wrote one decades ago at University of Toronto that's
still making the rounds (and a lot of other regex stuff
is lifted straight from it).

I don't see how using an existing library is reinventing the wheel.
