Looking for a regex to match a gmail plus address

Question

Im using this currently :

/^(.*)\\+(.*)@gmail.com/

(I\'m capturing the text before and after the plus sign in a group)

and it works in most

Answer 1

You can use [] with ^ (all the chars but...) e.g.

echo 'aaa++++bbb@gmail.com' | perl -p -e 's/^([^\+]*)\+(.*)@gmail.com/$1/'

Answer 2

(.*?)\++(.*?)@gmail.com should work.

Answer 3

[a-zA-Z0-9]{1,}[\+]{0,}[a-zA-Z0-9]{0,}@gmail.com

Answer 4

If you don't care about validating the first portion of the address (prior to any '+') you could go with /^([^+]+)(:?+[^+]*)*@gmail.com/ to just the first part.

You may want to do better validation on that to ensure that it is a "valid" account format, according to whatever rules are set forth by RFC.

edit -- asterisks were making a bold statement.

Answer 5

you need to escape the + sign : /^(.+?)\++(.+?)@gmail.com/

EDIT : your post was misformatted : your + is already escaped

Answer 6

You are not properly detecting the +. Use something like this: ^([^+]+)[+]+([^+]+)@gmail.com
