Which Regular Expression Library is Right for Your C Project?

Regular Expression Libraries for C

When incorporating regex capabilities into C code, it's crucial to select an appropriate library. Here are some popular options commonly recommended by experienced programmers:

Boost.Regex

Boost.Regex is a highly regarded library that adheres to the proposed C 0x standard and is now included in TR1. It offers a comprehensive set of features and is often the preferred choice.

Boost.Xpressive

For those seeking a more user-friendly experience, Boost.Xpressive is an excellent header-only library that introduces a novel aspect: static regexes, which enable compilation of regexes during the compilation process.

std::regex (C 11)

For users employing a C 11 compliant compiler, such as the latest version of GCC, std::regex offers a powerful native solution that simplifies regular expression handling.

Additional Considerations:

When making your selection, consider factors such as the licensing terms (e.g., the GPL license of http://freshmeat.net/projects/cpp_regex/ may not be suitable for commercial projects). Additionally, evaluate the specific features and ease of use that best align with your project's requirements.
