Ruby Question

Doesn't Ruby have isalpha?

Like Python? I'm trying to check whether each character in a string is an alphanumeric or not?

Answer

There's a special character class for this:

char.match(/^[[:alpha:]]$/)

That should match a single alphabetic character. It also seems to work for UTF-8.

To test a whole string:

string.match(/^[[:alpha:]]+$/)

Keep in mind this doesn't account for spaces or punctuation.
