Javascript Regexp to match a string which isn't

Question

Given this regexp:

@([a-z0-9_-]{3,})

I don't want it to match if the pattern is "SpecialUsername".

@Tom = match
@SpecialUsername = no match
@Another = match
etc

How do I modify it for this special case?

If your blacklist is only the one name, I wouldn't modify the regex. Just do a separate check, if possible. — aebabis

so it should probably be something like @(?!SpecialUsername)([a-zA-Z0-9_-]{3,}) ?
