About:
CTRE (Compile-Time Regular Expressions) is a header-only C++20 library that enables pattern matching using PCRE-like syntax directly within the code. It performs all regex parsing and optimization during compilation, eliminating runtime overhead and catching syntax errors early. This results in significantly faster execution compared to traditional regex libraries.
Key Features:
  • Compile-time parsing and optimization
  • Zero runtime dependencies
  • PCRE-compatible syntax
  • Exception-safe by design
Use Cases:
  • High-performance string parsing in C++ applications
  • Embedded systems requiring minimal runtime overhead
  • Protocol parsing and validation
Alternatives:
  • std::regex – Standard library solution but slower runtime performance
  • Boost.Regex – Mature alternative with runtime overhead but broader feature set
