## What it is
ChaiScript is a header-only embedded scripting language designed from the ground up for seamless integration with modern C++ applications. It provides type-safe bidirectional calls between C++ and scripts, supporting callbacks, overloaded functions, class methods, and STL containers.

## Use cases
- embed a scripting language in a C++ application
- let users extend my C++ program with scripts
- call C++ functions from a script type-safely
- expose C++ classes and STL containers to scripts
- add a header-only scripting engine without external dependencies

## When to choose
- you need an easy-to-integrate, header-only scripting layer for a C++17 codebase
- type safety between C++ and scripts matters
- you want thread-safe scripting with no preprocessor or external tools

## When to avoid
- you need a general-purpose standalone scripting language like Python or Lua
- your project targets compilers older than C++14/17
- you need a scripting language with a large ecosystem of libraries

## Facets
- artifact type: library
- maturity: maintenance
- function: interpreter, programming-language
- domain: programming-languages, developer-tools
- platform: cpp, cross-platform
- tags: embedded-scripting, header-only, scripting-language, type-safe
