edge case handling about stringex HOT 2 CLOSED

What type of behaviour would you want in this case? I think an empty string is a good return value in this case which would then leave you to check if the return is empty (which you probably should be checking anyway). The alternative would be to return nil if the string is empty but I think a contract of String in String out for #to_url is a better pattern.

nope, absolutely fine. I'll just add a custom validation to check whether the generated permalink is not valid and add an error to the 'name' (since the user will never directly enter a permalink and might need a useful description why his 'name' isn't valid)
