## Sol
|
|
|
|
[](https://travis-ci.org/Rapptz/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
|
|
|
|
```cpp
|
|
#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);
|
|
}
|
|
```
|
|
|
|
```cpp
|
|
#include <sol.hpp>
|
|
#include <cassert>
|
|
|
|
struct vars {
|
|
int boop = 0;
|
|
};
|
|
|
|
int main() {
|
|
sol::state lua;
|
|
lua.new_userdata<vars>("vars", "boop", &vars::boop);
|
|
lua.script("local beep = vars.new()\n"
|
|
"beep.boop = 1");
|
|
assert(lua.get<vars>("beep").boop == 1);
|
|
}
|
|
```
|
|
|
|

## 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. However, the
|
|
officially supported compilers are:
|
|
|
|
- GCC 4.8.0
|
|
- GCC 4.9.0
|
|
- Clang 3.4
|
|
|
|
Visual Studio 2013 with the November CTP could possibly compile it, despite not being explicitly supported. The last
|
|
version that Visual Studio 2013 was supported was on tag v0.9.0. Anything after that is wishful hope. In order to retrieve
|
|
that tagged version, just do `git checkout v0.9.0`.
|
|
|
|
## 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>`.

## TODO
|
|
|
|
- Possibly document functions and classes via doxygen.
|
|
- Provide more examples to showcase uses.
