Hey all,
Just wondering, what is the equivalent of python's exec() function in lua?
Here's an example of the syntax-

Code:

a="pri"
b="nt 12345"
exec(a+b)

and the output-

Code:

I've googled this, but to no avail...

anyway, thanks for any help.

Not 100% sure is one exists but what you can do as a work around is write the string to a file and use Lua's dofile( "filename" ) to execute it.

A little googling on "lua dofile" turns up this page, which does a decent job of explaining 'loadstring', which may well be what you're looking for.

Code:

a = "prin"
b = "t(1234)"
loadstring(a..b)
