Email regex not valid

[Vadorequest]

Hi! Another regex issue :)

Here is my regex, in the model:

validates :email, format: { with: /\A\s*(([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})[\s\/,;]*)+\Z/i }

Here is the generated data-validate attribute on the view.

data-validate="[{"kind":"presence","options":{},"messages":{"blank":"skal udfyldes"}},{"kind":"format","options":{"with":"(?i-mx:\\A\\s*(([^@\\s]+)@((?:[-a-z0-9]+\\.)+[a-z]{2,})[\\s\\/,;]*)+\\Z)"},"messages":{"invalid":"er ikke gyldig","blank":"skal udfyldes"}}]"

I'm not a pro in regex but it looks like the \ is doubled due to some conversion. And obviously the regex doesn't works with valid emails.

[1] pry(main)> JSON.dump(:with => /abc/)
=> "{\"with\":\"(?-mix:abc)\"}"

Any work around?
Thanks.

The problem was that the email regex was Ruby specific.

/^\s*(([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})[\s\/,;]*)+$/i
