Thanks for the tutorial!
But I think you have an error in the fib function! If you really start with
my $last = 0;
and your fib function, you'll get this error, as you've produced a never ending recursion:
Deep recursion on subroutine "IkiWiki::Plugin::fib::fib" at ./fib.pm line 29.
So the fib function should better look like this, which is its true definition (see [[Wikipedia|http://de.wikipedia.org/wiki/Fibonacci-Folge]], for example):
sub fib {
my $num=shift;
return 0 if $num == 0;
return 1 if $num == 1;
return fib($num - 1) + fib($num - 2);
}
Just as a hint for people who run into this error while doing this tutorial.
