How do I match everything after @ until space?

Question

I have this string:

var str = 'این یک @پیا.م تست است';
// I want this     ^^^^^

I can select it like this:

/@(.{5})/

But it isn't what I need, because the length of that word which is after @ and before space isn't always 5. I really don't know why \w doesn't matches Persian characters. Or even [a-zA-Z] doesn't work either.

Well, how can I do that?

Answer 1

As a Unicocde independent approach you can simply use a negated character class :

'@([^ ]+)'

See demo https://regex101.com/r/oD9hV0/1

Answer 2

You could use the follwing regex That will return anything beteen @ and fot . :

@(.*?)[\s]

@ : matches the character @ literally

(.*?) : matches any character (except newline)

\s : match any white space character [\r\n\t\f ]

Hope this helps.
