ECMAscript?? Ewww... Go Perl :-)

Yeah, Perl would be a better example, but IIRC the regex syntax is
different, and I only know ECMAScript regex syntax.

All regex is based on grep somewhat. They are all very similar.
Though... if ECMAscript has grouping and all that, they must
be virtually identical.

I have no clue about ECMA, but I'm almost certain that Perl can
make any challenge you throw at it. Especially with its massive
library.

Perl + ImageMagick API and ~50 lines of code can do things that
whole applications cannot do to pictures without significant
effort/plugins for example.

if(string =~ m/\(?\d{3}\)?\s*\d{3}(-|.)?\d{4}/ )

There, and no nasty || statements making the example
excessivly long.

The reason for the || is to break it up so that you don't have lots of |
in the expression. Your version wouldn't work since it would also
match:

(202 555.1212

And doesn't match:

202/555-1212

Toche. For the latter example, I shall do d{3}[\)\/]? and that fixes
it :-)

For the earlier example, meh, I give up. Use your stupid ||
statements. :-p

Took about 1 minute but no test yet; cause I suck with Perl
and don't feel like compile-checking :-p

Does ECMAscript have grouping? In Perl you can just
do \d{3}(-|.)?\d{3} and that will match each of the following:

Yes, I used it in the other example.... :)

You did? Where? :-p
