Questions tagged [chaiscript]

ChaiScript is an embeddable scripting language inspired by JavaScript. It is designed as header-only library that is directly targeted at C++.

ChaiScript describes itself as an easy to use embedded scripting language for C++. Some key features:

  • Header only; no external library is necessary, just a C++11 compiler.
  • Thread safe by default
  • Portable; tested on 32 and 64 bit Windows, clang++ and g++
  • BSD licensed

More info:

A tiny example:

#include <chaiscript/chaiscript.hpp>

std::string helloWorld(const std::string &t_name)
{
  return "Hello " + t_name + "!";
}

int main()
{
  chaiscript::ChaiScript chai;
  chai.add(chaiscript::fun(&helloWorld), 
           "helloWorld");

  chai.eval("puts(helloWorld(\"Bob\"));");
}
