Which Regex Library is Right for C Development?

Recommending Regex Libraries for C Development

When working with regex in C/C , developers have several options to consider. Here are some recommended libraries:

Boost.Regex

Boost.Regex is widely used and is expected to become part of the C 0x standard. It is a reliable and feature-rich library.

Boost.Xpressive

Boost.Xpressive offers a header-only library that is known for its ease of use, particularly for static regex compilation at compile time.

std::regex (C 11 onwards)

For C 11 compliant compilers, std::regex is the recommended choice. It is a part of the C standard library and provides a comprehensive set of regex functionality.

Additional Considerations

• Licensing: Boost.Regex and Boost.Xpressive are licensed under the Boost Software License, which permits their use in commercial projects.
• Header-only: Boost.Xpressive and other header-only libraries can be easily integrated into projects without the need for additional compilation steps.
• Compiler Support: For full compatibility with std::regex, a C 11 compliant compiler is required. Consider Boost.Regex or Boost.Xpressive for earlier versions of C .
