Question

I have std strings like these:

UserName: Message

At first look it seems like an easy problem, but this issue is in that the name’s last character could be a ‘:’ and the first letter of the message part of the string could be a ‘:’ too. The user could also have spaces in their name.

So A user might be names ‘some name: ‘
and might type a message ‘ : Hello’

Which would look like:
‘some name: : : Hello’

I do have the list (vector) of usernames though.

Given this, is there a way I could extract the username from this sort of string? (Ideally without having to iterate through the list of users)

Thanks

Try a regex like (\w+?):\ \w+.
