EmailTypo
EmailTypo is a Ruby gem that gives you an easy, tested method that fixes email typos.
As an example: A user with the email "[email protected]" accidentally enters in "[email protected]", EmailTypo will fix it automatically.
EmailTypo is concerned with incorrectly-entered data (email provider names, TLDs), not with evaluating whether a particular domain is valid, or whether a particular email address is legitimate. (That is, it's focused on fixing the part that comes after the "@" in the email address.) It works really well for helping you — and your users — when they accidentally type something in wrong.
NOTE: This is based on https://github.com/charliepark/fat_fingers, but without polluting the String
class and with easier extension support.
Installation
Add this line to your application's Gemfile:
gem "email_typo"
And then execute:
$ bundle
Or install it yourself as:
$ gem install email_typo
Usage
To fix any typos, just use EmailTypo.fix(email)
.
EmailTypo.fix("[email protected]")
#=> "[email protected]"
To add/change the processors, add any object that responds to #call(email)
to EmailTypo.default_processors
. The following example adds a processor for .uol.com.br
, a Brazilian email provider:
EmailTypo.default_processors << lambda do |email|
email.gsub(/@uol\.com(\..*?)?/, "@uol.com.br")
end
