# Elba

[![Build Status](https://secure.travis-ci.org/Muon/elba.png)](http://travis-ci.org/Muon/elba)

Elba is a simple-to-use library designed to enable the easy bridging of the
chasm between the worlds of C++ and Lua 5.1. At the moment, Elba is incomplete
and lacks documentation, so it is not recommended for production usage.

## Example

### Simple `elba::reference`-based manipulation

```c++
#include 
#include 

void report(const char* str)
{
	std::cout << str << std::endl;
}

int main()
{
	elba::state L;
	L.open_libs();

	elba::reference print = L.globals()["print"];
	print("C++ to Lua, C++ to Lua, over *kzzzht*");

	L.globals()["report"] = report;
	L.do_string("report('Lua to C++, report! *kzzzht*')");

	return 0;
}
```

### Binding classes

```c++
#include 

class Counter
{
public:
	Counter() : counter(0) {}

	void increment() { ++counter; }
	void decrement() { --counter; }
	int count() const { return counter; }

private:
	int counter;
};

int main()
{
	elba::state L;
	L.open_libs();

	elba::class_binder(L, "Counter")
		.constructor()
		.set("increment", &Counter::increment)
		.set("decrement", &Counter::decrement)
		.set("count", &Counter::count)
		.set("primary_counter", Counter());

	L.do_string(
		"a = Counter.new() \
		print(a:count()) \
		a:increment() \
		print(a:count()) \
		print(Counter.primary_counter:count())"
	);

	return 0;
}
```
