Bill,

Not quite. I want 3 arrays total, not n number of 3 element arrays.

>> ("a".."z").to_a / 3
=>
[["a", "b", "c", "d", "e", "f", "g", "h", "i"],
 ["j", "k", "l", "m", "n", "o", "p", "q", "r"],
 ["s", "t", "u", "v", "w", "x", "y", "z"]]

Brandon: Andrew’s is almost right, isn’t he? Just skip the transpose (which I didn’t know about incidentally) and it works…

(“A”..”Z”).to_a.in_groups_of(3) [“D”, “E”, “F”], [“G”, “H”, “I”], [“J”, “K”, “L”], [“M”, “N”, “O”], [“P”, “Q”, “R”], [“S”, “T”, “U”], [“V”, “W”, “X”], [“Y”, “Z”, nil]]

Andrew,

Except that I want them group as A-I, J-R, and S-Z, not every 3rd letter.

(“A”..”Z”).to_a.in_groups_of(3).transpose

Facets has something like this. Uncovered this with Eli back when we reworking some Rake tasks: http://facets.rubyforge.org/doc/api/core/index.html

That was way after I created a Multiterator to do the same thing. IT went something like: Multiterator(array, 3).each { |a, b, c| puts a + b + c }

+1 for Ruby 1.9 having something that does this.

Something similar was actually talked about here: http://blog.jayfields.com/2007/09/ruby-arraychunk.html
