this triggered overhaul of set_function/pusher<function_t>::push(...) both state and table reflect changes to userdata structure to make it easier to use tests updated to account for overload resolution some function-related traits added to make use easier -- cleaned up archaic typenames in function_types.hpp Account for std::reference_wrapper for objects -- sol now uses copy-by-default (value-semantics) for all functors updated tests to reflect this |

Sol
Sol is a C++ library binding to Lua. It currently supports Lua 5.2. Sol aims to be easy to use and easy to add to a project. At this time, the library is header-only for easy integration with projects.
Sneak Peek
#include <sol.hpp>
#include <cassert>
int main() {
sol::state lua;
int x = 0;
lua.set_function("beep", [&x]{ ++x; });
lua.script("beep()");
assert(x == 1);
}
More examples are given in the examples directory.
Features
- Supports retrieval and setting of multiple types including
std::string. - Lambda, function, and member function bindings are supported.
- Intermediate type for checking if a variable exists.
- Simple API that completely abstracts away the C stack API.
operator[]-style manipulation of tables is provided.- Support for tables.
Supported Compilers
Sol makes use of C++11 features. GCC 4.7 and Clang 3.3 or higher should be able to compile without problems. Visual Studio 2013 with the November CTP should be able to support this as well.
Caveats
Due to how this library is used compared to the C API, the Lua Stack is completely abstracted away. Not only that, but all Lua errors are thrown as exceptions instead. This allows you to handle the errors gracefully without being forced to exit.
It should be noted that the library itself depends on lua.hpp to be found by your compiler. It uses angle brackets, e.g.
#include <lua.hpp>.
License
Sol is distributed with an MIT License. You can see LICENSE.txt for more info.
TODO
- Possibly document functions and classes via doxygen.
- Provide more examples to showcase uses.
