How to combine two lists in one list? using notepad++ regex?

Question

I have a list of textfile such as below example:

username1
username2
username3

I want a regex that can make it like following example:

username1:username1
username2:username2
username3:username3

etc..

I've tried many regex with failed attempts.

What is the rule here? Just duplicate the whole line after a `:`? — Wiktor Stribiżew, Nov 15 '16 at 16:43
Just replace `.+` with `$0:$0` - my guess is you haven't tried hard enough. — Lucas Trzesniewski, Nov 15 '16 at 16:43
