Link	Info	Description
Relaxing the One Definition Rule in Interpreted C++	Javier Lopez Gomez et al. 29th International Conference on Compiler Construction 2020	This paper discusses how Cling enables redefinitions of C++ entities at the prompt, and the implications of interpreting C++ and the One Definition Rule (ODR) in C++
Cling – The New Interactive Interpreter for ROOT 6	V Vasilev et al 2012 J. Phys.: Conf. Ser. 396 052071	This paper describes the link between Cling and ROOT. The concepts of REPL and JIT compilation. Cling’s methods for handling errors, expression evaluation, streaming out of execution results, runtime dynamism.
Interactive, Introspected C++ at CERN	V Vasilev, CERN PH-SFT, 2013	Vassil Vasilev (Princeton University) explains how Cling enables interactivity in C++, and illustrates the type introspection mechanism provided by the interpreter.
Introducing Cling, a C++ Interpreter Based on Clang/LLVM	Axel Naumann 2012 Googletechtalks	Axel Naumann (CERN) discusses Cling’s most relevant features: abstract syntax tree (AST) production, wrapped functions, global initialization of a function, delay expression evaluation at runtime, and dynamic scopes.
Creating Cling, an interactive interpreter interface	Axel Naumann 2010 LLVM Developers’ meeting	This presentation introduces Cling, an ahead-of-time compiler that extends C++ for ease of use as an interpreter.
