Answer 1

Guess no regex is perfect for this use. I found a pretty solid one here

/(?:(?:https?|ftp|file):\/\/|www\.|ftp\.)(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[-A-Z0-9+&@#\/%=~_|$?!:,.])*(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[A-Z0-9+&@#\/%=~_|$])/igm

Some differences / advantages compared to the other ones posted here:

• It does not match email addresses
• It does match localhost:12345
• It won't detect something like moo.com without http or www
