Add ^ as
[^a-zA-Z0-9]
Though there are probably a number of different ways to approach RegEx…

If you add an underscore (the equivalent of \w): [a-zA-Z0-9*_*]
Then \W is the opposite.
If you wanted to not match [a-zA-Z0-9]
You could do
$string !~ m/[a-zA-Z0-9]/

Hello
I know [a-zA-Z0-9] means words and numbers.
But what's the reverse of this regex?
Thank you.
Yes I understand now. For some reason I missed the
missing quotes in the original post and the word token
came to mind.
$ perl -MO=Deparse foo.plx
BEGIN { $^W = 1; }
use diagnostics;
sub abc {
use warnings;
use strict 'refs';
'abc.';
}
sub e {
use warnings;
use strict 'ref

Why is $_=abc.e.i short for
$_ = 'abc' . 'e' . 'i';
Is it b/c each group of characters is a 'token'
including the periods?
abc => token
. =>
I have to say - I am totally enamored with regex. Color me
'goober'. I just think that is a beautiful, concise, elegant way to
make a substitution. All of that capability in one short string of
characters... No if, then, else construct. Just - capture what is
there; if it matches a .\w

This is short for:

Which is the same as saying:

Thanks.I never knew that it can write a string like this way.
You probably shouldn't though. It is a carry over from the earli

I think you will be less confused if you change the
