Lua 'require' but files are only in memory

Question

Setting: I\'m using Lua from a C/C++ environment.

I have several lua files on disk. Those are read into memory and some more memory-only lua files become available duri

Answer 1

Instead of replacing require, why not add a function to package.loaders? The code is nearly the same.

int my_loader(lua_State* state) {
    // get the module name
    const char* name = lua_tostring(state);
    // find if you have such module loaded
    if (mymodules.find(name) != mymodules.end())
    {
        luaL_loadbuffer(state, buffer, size, name);
        // the chunk is now at the top of the stack
        return 1;
    }

    // didn't find anything
    return 0;
}

// When you load the lua state, insert this into package.loaders
