you have ri [1], which is an interactive Reference.
(copied straight from 1:)
$ ri each_with_index
--------------------------------------------------------
enumObj.each_with_index {| obj, i | block } -> nil
--------------------------------------------------------
Calls block with two arguments, the item and its index,
for each item in enumObj.
hash = Hash.new
%w(cat dog wombat).each_with_index {|item, index|
hash[item] = index
}
hash #=> {"dog"=>1, "wombat"=>2, "cat"=>0}
this is a very good reference. it is not good for learning the language, but
there are at least two very good books online.
