It's all in the manual, which you consistently ignore. Please do have
a look at it.

The [: ... :] character classes only go into the character class brackets
(i.e. [ ... ]). So you need two pairs of brackets, like so: [[:alpha:]].

Yes, it looks strange. But it starts making sense when you want to combine
things (e.g. alpha plus comma or dash: [[:alpha:],-])

Please, look into the manual. It takes some effort, but it's worth it.

Cheers
