## What it is
xeus-cling is a Jupyter kernel for the C++ programming language, built on the Cling C++ interpreter and the native xeus implementation of the Jupyter protocol. It lets users run C++ code interactively in Jupyter Notebook or JupyterLab.

## Use cases
- run c++ interactively in jupyter notebooks
- teach c++ in a notebook environment
- prototype c++ code without compiling full projects
- explore c++ standard library features in a repl
- create executable c++ tutorials and documentation

## When to choose
- you want an interactive C++ REPL inside Jupyter Notebook or JupyterLab
- you are teaching or learning C++ and want immediate feedback
- you need to mix C++ code cells with markdown documentation
- you work on Linux or macOS and use conda/mamba

## When to avoid
- you need Windows support, since no packages are provided
- you need the latest C++ standards beyond what Cling supports
- you want to build production C++ applications rather than experiment
- you cannot use conda/mamba and building from source is impractical

## Facets
- artifact type: plugin
- maturity: active
- function: interpreter, developer-tools, documentation
- domain: developer-tools, education, programming-languages
- platform: python, cpp, cross-platform
- tags: jupyter-kernel, cling, interactive-cpp, notebooks, repl, linux, macos
