About:
Sfsexp is a lightweight C library designed for parsing and manipulating S-expressions with high performance and minimal memory overhead. It provides a simple API for reading, writing, and traversing nested data structures commonly used in configuration and data serialization. Its main value proposition is delivering a small footprint and fast execution speed suitable for embedded systems and performance-critical applications.
Key Features:
  • Small memory footprint and lightweight design
  • Fast parsing and processing capabilities
  • Simple C API for easy integration
  • No external dependencies
Use Cases:
  • Parsing configuration files in embedded systems
  • Data serialization/deserialization in C applications
  • Implementing Lisp-like language interpreters
Alternatives:
  • libsexp – Similar functionality but Sfsexp is optimized for speed and minimal resource usage
  • Boehm GC S-Expressions – More heavyweight with garbage collection dependency, while Sfsexp is dependency-free
