LuaD: How to load modules

[Chris via Digitalmars-d-learn]

I'm using / testing LuaD atm. It works very well, however, I've 
encountered a problem. When I load the module lualsp (for lua 
server pages) the app crashes. If I run the lua script on its own


$ lua5.1 test.lua

it works perfectly fine. The lua server page is executed 
correctly. If I run the same script from within LuaD, the app 
crashes, same goes for


lua.doString(require \lualsp\);

I haven't been able to figure out how to load the module into lua 
correctly, obviously there is something going wrong. I hope there 
is a way.


The script test.lua:

-- test.lua
require lualsp

-- function from lualsp module written in C++
dofile_lsp(../examples/example1.html)
-- end test.lua

The lsp file:

html
  body

? name = Chris?

? print(name) ?

  /body
/html

What works is when I compile lualsp into a static library and 
then link my program against it. Then I can do:


lua_State* L = luaL_newstate();
auto lua = new LuaState(L);
lua.openLibs();
int lib = luaopen_lualsp(L);  // defined in llsplib.cpp (i.e. the 
module)


if (lib == 0) {
  auto lsp = lua.get!LuaFunction(dofile_lsp);
  lua.doString(dofile_lsp('path/to/example1.html'));
}

But I want to be able to load an external library dynamically.
