Cling is an interactive C++ interpreter built on top of Clang and LLVM, implementing a read-eval-print loop (REPL) for rapid C++ development. It also serves as the basis for a Jupyter kernel for C++.
Use cases
- run C++ code interactively in a REPL
- prototype C++ snippets without compiling a full program
- use C++ in Jupyter notebooks
- teach and learn C++ with instant feedback
- incrementally evaluate C++ expressions and statements
When to choose
- you want a REPL or interactive session for C++
- you need a C++ kernel for Jupyter
- you want rapid experimentation with C++ code using Clang-quality diagnostics
When to avoid
- you need a production compiler toolchain rather than an interpreter
- you require fully supported prebuilt binaries for all platforms
- you need a lightweight tool without heavy LLVM/Clang dependencies
