直接上代码：
1：c++代码
#include <lua.hpp>
#include <LuaBridge/LuaBridge.h> #include <iostream>
#include <string> class A
{
public:
void action()
{
std::cout<<"Hello I am A\n";
} virtual void doPrint(int a,int b)
{
std::cout<<"in A a:"<<a<<"b:"<<b<<std::endl;
} std::string goodMan() const
{
return "goodman";
}
}; class B : public A
{
public:
void hello(const std::string& info) const
{
std::cout<<"hello:"<<info<<std::endl;
} virtual void doPrint(int a, int b) override
{
std::cout<<"in B just"<<(a + b) <<std::endl;
}
}; void globalFunction()
{
std::cout<<"hello this is a global func\n";
} bool reloadLuaScript(lua_State* L, const std::string& luafile)
{
int state = luaL_dofile(L, luafile.c_str());
if(state != LUA_OK)
{
return false;
}
return true;
} void registerClassAndFunctions(lua_State* L)
{
using namespace luabridge;
//注册全局函数和类函数
getGlobalNamespace(L).addFunction("gloabalFunction",globalFunction);
getGlobalNamespace(L)
.beginClass<A>("A")
.addFunction("action",&A::action)
.addFunction("doPrint", &A::doPrint)
.addFunction("goodMan", &A::goodMan)
.endClass()
.deriveClass<B,A>("B")
.addFunction("hello", &B::hello)
.endClass();
} void testCallLua(lua_State* L)
{
A a;
lua_getglobal(L,"testA");
luabridge::push(L, &a);
lua_pcall(L,1,0,0);
} int main(int argc, char** argv)
{
lua_State* L = luaL_newstate(); luaL_openlibs(L);
std::cout<<"try load file "<<argv[1]<<std::endl; auto ok = reloadLuaScript(L, argv[1]);
if(!ok)
{
std::cout<<"load lua file failed\n";
}
else
{
registerClassAndFunctions(L);
testCallLua(L);
}
lua_close(L);
L = nullptr;
}
2：Lua代码
--print("hello");
--[[
this is note
这个是多行注释
--]]
print("This is myWorld!\n");
function testA(a)
a:action();
a:doPrint(1,2);
end

3：编译运行

[root@10-120-10-106 NewChart]# g++ -std=c++11 -o testlua testLua.cpp -llua -ldl
[root@10-120-10-106 NewChart]# ./testlua abc.lua
try load file abc.lua
This is myWorld! Hello I am A
