Howling at the Moon: Lua for C++ Programmers
summary
Lua is an embeddable, tiny scripting language whose full runtime can be as small as 180 KB binary with a short reference manual and only eight basic data types. Functions are true first-class closures and tables are the single complex data structure, with metatables providing operator overloading and encapsulation. Integration with C++ uses a stack-based C API that solves ownership by keeping items on the VM stack; C++17 variants or small binding libraries (Luabind, Sol2) make type crossings ergonomic and you can often roll a custom binding quickly.
