Running lua code from a string

Is there any simple way to run lua code from a variable without creating a new file and running it?
Like, for example: an ssh server/client?

Thanks in advance and tell me if I need to include any more information as I've never posted on a forum before.

Please someone move this thread to the right place…
To run a function from a string, (that is called 'evaluating') you use loadstring(string) in lua 5.1- (computercaft) or load(string) in 5.2+
What it will do is compile the string to an anonymous function which can be run.

eg:

--Defining a string to use as function later
funcStr = "print('test')"
--Running it directly
loadstring(funcStr)()
--Defining a function from the string and running it
func = loadstring(funcStr)
func()

Correct me if i'm wrong, but I believe i'm not ^_^/>

You have two hands and a mouse, use them. There is a report button at the bottom of each post. Report the main post.

It only returns the function but doesn't actually run it. Didn't see the last part of the code ill try that. I used to play roblox and used that all the time and I hate to see it go. Any other ideas?

That last part worked thanks.


Umm… How do I close a thread?

You don't. We do, if we feel it's necessary. I will move this to Ask a Pro, but I'd also like to point out nsh, my remote shell program. Just in case you're looking for a complete ssh-type solution at some point.

Thank you but I'd like to have the thrill of writing my own. ;)/>
