utf8.match

if not utf8.match(edit,"^%u") then
-- the first letter not capitalized
end

How to make a check that all letters are small?

I have some code that checks if the first letter is capitalized. But I still don't understand how to use it back. At least some examples are needed. Where can I read more about this?

Hey,

Well you can use string.match and check whether there are any uppercase letters.
If it returns nill then all the letters are lowercase and everything is good.

if string.match(text, '%u') == nil then
	-- all chars are lowercase
else
	-- an uppercase letter is found
end

I hope I understood correct what you want to do.

This is what I need, thanks for the help.
