Question

I created this regex to match all words that start with “@” in my string, there could be something before the @ tokens as well. it works well but it also catches email addresses and i would like to fix that.

(?<=@)\w+\b

Example string would be:

hello @bob, how are you? @mark, @emma and @chief are with me. email me
at [e-mail]!

Can you help?

You could use the next expression:

\B@\w+

which starts at a non-word boundary (\B). You could also rewrite it using negative lookahead like this:

(?!\b)@\w+
