I've got a array that I need sorted in a certain way and I'm struggling to figure out how to make it happen the way I want.
Basically the array needs to be sorted like this:
[A, B, C, AA, AB, AF ]
that is, a single alpha character before it sorts the next character. However, what I end up with when I sort is:
[A, AA, AB, AF, B, C]
How would I sort A to Z then AA-ZZ?

array.sort_by {|s| [s.size, s]}

arr.sort do |x,y|
if x.length < y.length
return 1
elsif x.length > y.length
return -1
else
x <=> y
end
end

You should probably try the code you're providing as a solution. That
cuts down on the stuff that a) raises exceptions, and b) doesn't solve
the problem even when the exceptions are gone.

array.sort_by {|s| [s.size, s]}
That's an incredibly elegant solution, thanks for sharing!

In case you find the temporary structure created for sorting inelegant
you can do this:
irb(main):006:0* a = %w{A AA AB AF B C}
=> ["A", "AA", "AB", "AF", "B", "C"]
irb(main):007:0> a.sort {|x,y| (x.length <=> y.length).nonzero? or x <=> y}
=> ["A", "B", "C", "AA", "AB", "AF"]
Kind regards
