CLua

A little library and program which compiles lua code a direct machine code. Made specifically for functions. This can export lua functions to executable CPP/C functions. To: casted_lua_func(RDI(uint64_t), RSI(uint64_t), uint64_t*); from: lua_func(string1, string2, bool1, bool2, integer1, integer2) This is on a developing state, so expect bugs or crashes in final functions nor unions.

API

This is like the PUC Lua api, with some adds of LuaJIT. Helpers: CLUA::makeV(uint64_t, CLUA::TYPE) -> CLUA::VALUE CLUA::makeV_D(double) -> CLUA::VALUE CLUA::getVtype(CLUA::VALUE) -> CLUA::TYPE CLUA::getVdata(CLUA::VALUE) -> uint64_t CLUA::isVdouble(CLUA::VALUE) -> bool getLuaTypeString(LuaType) -> std::string

Basic example for CLua JIT

-- Let's suppose this is on luatest.lua
function _sayHelloWorld()
	print("Hello World!");
end

// clua_runtest.cpp
#include <clua.hpp> // Only one library...
int main() {
	// Initialize essential
	lua_ErrHandler *LEH = new lua_ErrHandler();
	Lua *m_lua = CLUA::create(LEH);
	// Get file "luatest.lua"
	std::ifstream inputFile("luatest.lua");
	std::string content((std::istreambuf_iterator<char>(inputFile)), std::istreambuf_iterator<char>());
	// Generate
	CLUA::function script = CLUA::gen(content);
	// Run the lua script
	script(0, 0, nullptr);
	// Now, search for _sayHelloWorld and run it.
	const char *name = "_sayHelloWorld"; // Name
	CLUA::STRING *tname = CLUA::doString(name, strlen(name));
	// Get it..
	CLUA::VALUE val = CLUA::table::getData_String(CLUA::world::m_general, tname, 0);
	if (!val) {
		// Failed somehow..
		return 1;
	} else {
		// Run it.
		CLUA::function fun = (CLUA::function)CLUA::getVdata(val);
		fun(0, 0, nullptr); // There's Hello World
	}
}
