Skype's Crazy Regex Easter Egg
I find it highly annoying that this, as far as I understand, really doesn't use regular expressions.<p>The s/that/this/ syntax is <i>not</i>, of course, a regular expression. The regular expression is the thing that <i>might</i> go into the "that" part, an expression that can match against several different inputs. If all it supports is literals, it's not really worth calling it a regular expression, in my opinion.<p>The article expresses this like so:<p><i>Some experimentation shows that it isn't a full regular expression engine, it will only do straight word substitution.</i><p>I think this is stretching it; sure all literal strings are regular expressions, but if that's all there is (i.e. no alteration, repeat etc), then why call it an RE at all?<p>Am I just being grumpy?
