-- Posted by h a t t at 8:07 am on July 14, 2008 If anyone knows regex please message me.  (I know this will probably be fruitless but whatever.) -- Posted by marshmellowman at 8:10 am on July 14, 2008 Obligatory XKCD comic: But sadly I don't know regex. -- Posted by h a t t at 8:24 am on July 14, 2008 I guess being entertained is better than nothing. -- Posted by Blue Baby at 6:38 pm on July 25, 2008 I know a little about automata theory and formal languages but if you're taking about how to use regex in programming languages (such as Regex class in Java), I don't know how to use it. But if you're taking about this, for example: L = {w element of sigma star | length of w is even} in regex is: L(((a+b)(a+b))*) then I might be able to help.
