A different sort

20 Dec

Turns out it’s basically a ‘sort’ operator, borrowed from Perl:

results.sort! { |a, b| a.lname <=> b.lname }

In this case, from an example I was studying and expanding upon here, ‘results’ is an array of similar Person objects each of which have an ‘fname’ and ‘lname’ attribute for first and last name respectively.  I wanted to sort them by last name before printing to the screen and found the syntax illustrated above as a solution.  Lo and behold, there’s my little UFO, just in time to sort things out before the Christmas rush and that pesky Mayan apocalypse from Planet X.
