String Question

[Maurize]

If i have a string ( for example: "+" ) how can i remove the "string" to get a normal symbol i can work with?

If you want remove '+' from string. You can use string.gsub

local s = '2 + 2' 
local s = s:gsub( '+', '' ) 
print( s ) -- 2 2 
  

You mean this?

he want to make :

from : '2 + 2'

to : 2 + 2

something like un-string

Okay. You can load this via function loadstring.

  
loadstring( 'n = 2 + 2' )( ) 
print( n ) -- 4 
  

You can't get operator '+' from string.
