Cling - The Interactive C++ Interpreter
Overview
Cling is an interactive C++ interpreter, built on top of Clang and LLVM compiler infrastructure. Cling realizes the read-eval-print loop (REPL) concept, in order to leverage rapid application development. Implemented as a small extension to LLVM and Clang, the interpreter reuses their strengths such as the praised concise and expressive compiler diagnostics.
See also cling's web page.
Please note that some of the resources are rather old and most of the stated limitations are outdated.

Installation
Release Notes
See our release notes to find what's new.
Binaries
Our nightly binary snapshots can be found [here](for download at https://root.cern.ch/download/cling/)
Building from Source with Cling Packaging Tool
Cling's tree has a user-friendly, command-line utility written in Python called Cling Packaging Tool (CPT) which can build Cling from source and generate installer bundles for a wide range of platforms. CPT requires Python 2.7 or later.
If you have Cling's source cloned locally, you can find the tool in
tools/packaging directory. Alternatively, you can download the script
manually, or by using wget:
wget https://raw.githubusercontent.com/root-mirror/cling/master/tools/packaging/cpt.py
chmod +x cpt.py
./cpt.py --check-requirements && ./cpt.py --create-dev-env Debug --with-workdir=./cling-build/
Usage
Full documentation of CPT can be found in tools/packaging.
/some/install/dir/bin/cling '#include <stdio.h>' 'printf("Hello World!\n")'`
To get started run:
/some/install/dir/bin/cling --help`
or type
/some/install/dir/bin/cling
[cling]$ .help`
Jupyter
Cling comes with a Jupyter kernel. After building cling,
install Jupyter and run jupyter kernelspec install cling. It requires a fairly
new Jupyter. Make sure cling is in your PATH when you start jupyter!
See also the tools/Jupyter subdirectory for more information.
