Hi
I am a Lua beginner, and I have a problem.
I want to let my users (designers) create some Lua functions, but I want to keep track of the function they create

So for example, I dont want them to give me this:

"function SayHello() print('hello') end"

I want them to give me these
- name: SayHello
- body: function () print('hello') end

And do along the lines like

luaL_loadstring(body);
lua_setglobal(L, name);

But this won't work because the function's body does not compile on its own.

Is there another way for me to do that, besides manually formatting the script like

sprintf(buffer, "%s =%s", name, body)

Thank you for your help

I did know that, I think I just didn't explain myself well.

Anyway I found this: http://stackoverflow...ion-in-lua?rq=1
And the poster had about the same question as me.

It turns out that returning the function chunk does the trick.

My data therefore is like this

• body = "return function (msg) print(msg) end"
  
• name = "print_message"
  

And my (pseudocode) is like this


void CreateFunc(char* name, char* body)
{
// verify if the function already exists
assert(!funcs.contains(name));

luaL_loadstring(L, body);
lua_pcall( L, 0, 1, 0 );
lua_setglobal(L, name);

funcs.insert(name)
}


I'm open to other suggestion or remarks of course
