About:
Cling is an interactive C++ interpreter built on the LLVM compiler infrastructure. It enables immediate feedback for C++ code execution without a separate compilation step. This makes it ideal for rapid prototyping, educational purposes, and exploring complex libraries interactively.
Key Features:
  • Interactive C++ REPL (Read-Eval-Print Loop)
  • Just-In-Time (JIT) compilation
  • Seamless interoperability with native C++
  • Built on industry-standard LLVM/Clang
Use Cases:
  • Learning and teaching C++ syntax and features
  • Data analysis and visualization using C++
  • Prototyping algorithms without build overhead
Alternatives:
  • CERN ROOT – Cling is actually a core component of the ROOT framework, but can be used standalone for general C++ interpretation.
  • Ch – A commercial C interpreter, whereas Cling is open-source and maintains full C++ standard compliance.
