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.
