Lua Eval

[raytrace]

In javascript there is an eval() function that changes a string to an expression such as eval("alert('hi')") which triggers an alert.

I'm trying to find a way of doing the same in lua. I've tried using _G[x] but this doesn't work for table values (e.g x = "a.b") or functions.

Any suggestions would be much appreciated thanks!

I've managed to find a suitable answer:

Register "raweval" in MMF2

On "raweval" Run string "e = " + MMF2StringParameter(1)

And in lua..

function eval(a)
raweval(a)
return e end

That sounds dangerous.

EDIT: That's a reply to your original post, not your solution, which is innovative, though I still can't see the need for it.

loadstr() in lua does the same as eval() in javascript, php etc.
