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.
