Question

I need to find strings like “@something” beginning with “@” with RegexKitLite. I’ve used regex “@[a-z]+”, and it works ok. But I need “@” only at the begin of words, so I’ve tried “\b@[a-z]+” and this time it doesn’t work. Any ideas how to make proper regex?

Answer 1

Try this here

(?<=\W|^)@[a-z]+

You can see it online here on Regexr

(?<=\W|^) is a lookbehind assertion that says, ensure that there is a non word character \W or the beginning of the string ^ before the @
