regular expressions (regex)

... if we run out of things to do
wikipedia: regular expression
http://www.regular-expressions.info/
tricky example : http://cs.marlboro.edu/code/perl/prime_regex/primes.pl

 A (fairly) standard way to specify pattern matching in strings.

 For example ".*\.txt" would match anything ending with ".txt" :
    .     any character
    *     0,1,2,... or any number of those
    \.    a period (the slash "escapes" the next char)
    txt   those characters

Java : http://www.regular-expressions.info/java.html
common lisp : There's a list at http://www.cliki.net/regular%20expression
perl : http://www.troubleshooters.com/codecorn/littperl/perlreg.htm and many others...
