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.
#include <elba.hpp>
#include <iostream>
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;
}#include <elba.hpp>
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<Counter>(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;
}operator[]-style table manipulation- primitive type and std::string assignment/retrieval
- binding functions
- retrieval of functions from the Lua state
- class binding
- class properties
- table iterators
- write documentation
