ri--Ruby Interactive reference ri displays descriptions of Ruby's built-in methods, classes, and modules. Run "ri each_with_index" and you get: -------------------------------------------------------- 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} Emacs interface by David Alan Black <dblack@candle.superlink.net> is also bundled.
