If statement caps sensitive

Does anyone know how to make a if statement not caps sensitive? I am making a login program. Help appreciated! :)/>

You don't. if is just if and not IF. That is how Lua works.

I has hoping if anyone know of any code that could do the comparison or convert all uppercase letters to lowercase or vice versa, but is wont be the end of the world is users need to get the capitals correct.

string.lower(text) will make text lower case.

You can convert a string to lower case ->

input1 = read() -- i.e. "Hello"
input2 = read() -- i.e. "hELLo"

lowercase1 = string.lower(input1) -- will be "hello"
lowercase2 = string.lower(input2) -- will be "hello"

if(lowercase1 == lowercase2) then
  -- there you go. this block will be executed, when your inputs match in non-case-sensitive manner
end

When dealing with passwords and things, you should consider not to do this, since you loose entropy and therefor security.
So there will be much more ways to get into a single account. i mean, in computercraft this has no effect, but sticking to good practices is always a nice thing to do.

I am creating a multi-user login system I am going to make the usernames not case sensitive but the passwords are, as is standard practice. Also, for security the passwords are stored in a hashed format preventing non-caps comparison.
