About Augmented Array:

The Ruby Array class is extended with some traversing/iterating methods and you will also be able to get and set the individual array elements with indexes as of the indexes were attributes of an array.

Example:

require 'augmented_array'

[nil,1,2,nil,3].nilitems # => 2

[1,2,3,4,5].sum # => 15

[1,2,3,4,5,6]/1 # => [[1], [2], [3], [4], [5], [6]] [1,2,3,4,5,6]/2 # => [[1, 2], [3, 4], [5, 6]] [1,2,3,4,5,6]/8 # => [[1, 2, 3, 4, 5, 6]] []/2 # => []

[1,2,3,4,5].middle # => 3 [1,2,3,4].middle # => [2, 3] [1].middle # => 1

ary = [1,2,3] ary.first = 20 ary.first # => 20

[1,1.0,"test",{:key => "value"}].describe # => [{1=>"Fixnum"}, {1.0=>"Float"}, {"test"=>"String"}, {{:key=>"value"}=>"Hash"}]

ary = [1,2,3] ary.last = 20 ary.last # => 20

[1,2,3,4,5].second_last # => 4 [1].second_last # => nil

ary = [1,2,3,4,5] ary.alternate # => [[1, 3, 5], [2, 4]] ary # => [1,2,3,4,5]

ary = [1,2,3,4,5] ary.alternate! # => [[1, 3, 5], [2, 4]] ary # => [[1, 3, 5], [2, 4]]

ary = [1,2,3,4,5,6,7] ary.second = 20 ary.third = 30 ary.fourth = 40 ary.fifth = 50 ary # => [1, 20, 30, 40, 50] ary.second # => 20 ary.third # => 30 ary._0 = 25 ary._0 # => 25 # Similar to ary.at(0) or ary.fetch(0) ary._1 = 10 ary._1 # => 10 ary._11 = 11 ary # => [25, 10, 30, 40, 50, nil, nil, nil, nil, nil, nil, 11]

ary.eachindex { |index| eval("p ary.#{index}") }

ary.eachindex { |index| eval("ary.#{index} = 10")
}
