Hello all,

I'm trying to create a regex to match Twitter usenames (@username): I
also need this regex to exclude e-mail addresses.

I'm using this regex currently:

{@([A-Za-z0-9_]+)}

which matches the following:

@foo

@foo: LOL u r gr8

bar(a)foo.com

I want to match the first two, but not the third. Any advice?

--Kevin

use: {^@([A-Za-z0-9_]+)}

I'd not use regex but rather: string match -nocase {@*} $testCase

I think it is much more readable.
