in reply to How do I easily turn a year array into a string

Just to be different (and because I don't like two element ranges):
#!/usr/bin/perl my(@yearArray) = (1992, 1994, 1995, 1997, 1998, 1999, 2000, 2002, 2004 +, 2005, 2006, 2007, 2008); my($anchor) = shift(@yearArray); my(@out) = $anchor; while (@yearArray > 1) { my $tmp = shift(@yearArray); push(@out, ($yearArray[0] == $anchor + 2 ? '-' : $tmp)); $anchor = $tmp; } push(@out, @yearArray); my $out = join(', ', @out); $out =~ s/(, -)+, /-/g; print $out, "\n";

This assumes that each element of @yearArray is numeric and that it is sorted in ascending order.
