Description
Gets the chunk from the given string.
(function) = loadstring(string,chunkname)
Loadstring is used mainly by some scripts and by the majority of exploiting scripts. It runs the string given inside its brackets as code. To load and run a given string, use the idiom:
assert(loadstring(s))()
Chunkname is used as the chunk name for error messages and debug information. When absent, chunkname defaults to the given string.
Parameters
string: (string) string to load and compile
chunkname: (string) is used as the chunk name for error messages and debug information optional
Return values
Returns (function) compiled chunk as a function, otherwise returns nil
Examples
local test = loadstring("print('Hello world!')")
test() --> Hello world!
-- same as above
local test = loadstring("print('Hello world!')")()
-- a calculator
local mathStuff = "5+5*3"
local resultOfMath = loadstring("return "..mathStuff)()
print(resultOfMath)
-- run string as code
local Code = "print('I love loadstrings!')"
loadstring(Code)()
