About:
SWIG (Simplified Wrapper and Interface Generator) is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. It works by parsing C/C++ header files and automatically generating wrapper code to enable cross-language integration. This allows developers to reuse existing C/C++ libraries while scripting in languages like Python, Ruby, or JavaScript.
Key Features:
  • Automatic wrapper generation from C/C++ headers
  • Supports multiple target languages including Python, Java, and Go
  • Handles complex C++ features like classes, templates, and overloading
  • Extensible via typemaps for custom data type conversions
Use Cases:
  • Creating Python bindings for existing C++ libraries
  • Exposing C functions to scripting languages for automation
  • Integrating legacy C code into modern web applications
Alternatives:
  • Cython – Python-specific, better for Python-C integration but less language-agnostic
  • pybind11 – Modern C++11 focus, seamless Python interoperability but C++ only
  • cffi – Python-focused, simpler for C but lacks C++ support
