error/exception hadling in luabind

Hello,

 

My question is how to handle errors that tells something more than "lua
runtime error". In my code I need multiple scripts for the single lua state
that shouldn't know about each other so I'm using lua code to load the
scripts (the code comes from this list by the way). Below is the example of
the code that I have problem with:

 

// C++

std::string scriptLoaderCode("function scriptloader (scriptTable,
scriptname)\n \

                              local mt = {__index=_G} \

                              setmetatable(scriptTable, mt) \

                              local chunk = loadfile(scriptname) \

                              setfenv(chunk, scriptTable)  \

                              chunk() \

                              end");

 

luaL_dostring(pLua, scriptLoaderCode.c_str());

  {

    luabind::object newtable = luabind::newtable(pLua);

    try

    {

      luabind::call_function<void>(pLua, "scriptloader", newtable,
"test3.lua");

    }    

    catch (luabind::error e)

    {

      std::cout << "exception:" << std::endl;

      std::cout << "\t" << e.what() << std::endl;

    }

  }

 

And the lua code (just a simple test from documentation):

 

// lua

 

class 'lua_testclass'

 

function lua_testclass:__init(name)

    self.name = name

end

 

function lua_testclass:print()

    print(self.name)

end

 

class 'derived' (lua_testclass)

 

function derived:__init() super('derived name')

end

 

function derived:print()

    print('Derived:print() -> ')

    lua_testclass.print(self)

end

 

a = derived()

a:print()

 

This gave me an error "lua runtime error" so basically I still have no idea
what is wrong with the code. My guess it that it might be caused by the fact
that I load scripts via luacode but still if there is a compilation problem
it should give me some hint.

 

Thanks
