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 is developed primarily under the root-project organization and leverages Clang's compiler diagnostics for an interactive experience.

Use cases

• run C++ code interactively in a REPL
• experiment with C++ snippets without writing a full program
• rapid prototyping of C++ algorithms
• teach and learn C++ interactively
• incrementally load and test C++ libraries
• embed a C++ interpreter in an application

When to choose

• you want a REPL for C++ similar to Python's interactive shell
• you need on-the-fly C++ interpretation for teaching or prototyping
• you want to script C++ without a compile-link-run cycle
• you work with ROOT or scientific computing workflows that use Cling

When to avoid

• you need a production compiler rather than an interpreter
• you require a lightweight tool without heavy LLVM/Clang dependencies
• you need a stable binary release and cannot build from source
• your project targets only the latest C++ standards beyond what Cling supports
