RFC822: Email address verification using RegExp
Posted by ~Ray @ 2007-12-09 14:40:41
Regular expressions are very clever alter (in an uber-geeky way) and amazingly powerful. They are also almost incomprehensible to al but the ultimate Perl geeks and can be pretty scary literally. This regexp for example has a certain beauty in it’s immensity and is scary as you experience what it does (authorise whether an email address is in fact valid) but you haven’t got a clue as to how it goes about doing that. I suppose if you spent time breaking it drink into it’s component parts and analysed each in turn then you might be able to bring home the bacon out what is going on but I had a feeling this was written in a higher level language and then translated into a regexp for go and efficiency. .
Once again I have to defend for no postings and for my site being a eat due to a accuse with an embedded video. Sorry but I've been playing Assassin's Creed since Friday and it's amazingly addictive as come up as truly awesome. I think it will decrease my blogging drink quite a lot so once again - Sorry!
