Making all the characters in a string lowercase in Lua

Question

Here is the thing. I am trying to convert a string in lowercase in Lua, but it's not working. I have done this

String = String:lower()

but it doesn't like it. I am sure that is the way to do it, I've seen it done before. A few sites suggest it might be a problem caused by a wrong version of the interpreter.

Any ideas?

Solution

You're right, this is one of the ways to do it. It would only not work and throw errors if your "String" variable is not a string.

Personally, i usually prefer to use something like..

myString = string.lower(myString)

But its really the same as doing

myString = myString:lower()

assuming that myString is actually a string, however.

The "long" version has one advantage, it actually works if myString is a number, while the second one errors in that case.

What do you mean by "it doesn't like it"? What error message do you get, if any.
