|
|
|
Sol is a C++ library binding to Lua. It currently supports all Lua versions 5.1+ (LuaJIT 2.x included). Sol aims to be easy to use and easy to add to a project.
|
|
The library is header-only for easy integration with projects.
|
|

|
## Documentation
|
|
|
|
Find it [here](http://sol2.rtfd.io/). A run-through kind of tutorial is [here](http://sol2.readthedocs.io/en/latest/tutorial/all-the-things.html)! The API documentation goes over most cases (particularly, the "api/usertype" and "api/proxy" and "api/function" sections) that should still get you off your feet and going, and there's an examples directory [here](https://github.com/ThePhD/sol2/tree/develop/examples) as well.
|
|
|
|
## 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_usertype<vars>("vars", "boop", &vars::boop);
|
|
lua.script("beep = vars.new()\n"
|
|
"beep.boop = 1");
|
|
assert(lua.get<vars>("beep").boop == 1);
|
|
}
|
|
```
|
|
|
|
More examples are given in the examples directory.

## Creating a single header
|
|
|
|
You can grab a single header out of the library [here](https://github.com/ThePhD/sol2/tree/develop/single/sol). For stable version, check the releases tab on github for a provided single header file for maximum ease of use. A script called `single.py` is provided in the repository if there's some bleeding edge change that hasn't been published on the releases page. You can run this script to create a single file version of the library so you can only include that part of it. Check `single.py --help` for more info.

## Features
|
|
|
|
- [Fastest in the land](http://sol2.readthedocs.io/en/latest/benchmarks.html) (see: sol bar in graph).
|
|
- Supports retrieval and setting of multiple types including `std::string` and `std::map/unordered_map`.
|
|
- 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, including `protected_function` with the ability to use an error-handling function.
|
|
- `operator[]`-style manipulation of tables
|
|
- C++ type representations in lua userdata as `usertype`s with guaranteed cleanup.
|
|
- Customization points to allow your C++ objects to be pushed and retrieved from Lua as multiple consecutive objects, or anything else you desire!
|
|
- Overloaded function calls: `my_function(1); my_function("Hello")` in the same lua script route to different function calls based on parameters
|
|
- Support for tables, nested tables, table iteration with `table.for_each` / `begin()` and `end()` iterators.
|
|
|
|
## Supported Compilers
|
|
|
|
Sol makes use of C++11/14 features. GCC 4.9 and Clang 3.4 (with std=c++1z and appropriate standard library) or higher should be able to compile without problems. However, the
|
|
officially supported and CI-tested compilers are:
|
|
|
|
- GCC 4.9.0+
|
|
- Clang 3.5+
|
|
- Visual Studio 2015 Community (Visual C++ 14.0)+
