Using Tuples in Ruby?

Question

Does anyone use tuples in Ruby? If so, how may one implement a tuple? Ruby hashes are nice and work almost as well, but I\'d really like to see something like the Tuple clas

Answer 1

I'm the author of Gem for Ruby tuples.

You are provided with two classes:

• Tuple in general
• Pair in particular

You can initialize them in different ways:

Tuple.new(1, 2)
Tuple.new([1, 2])
Tuple(1, 2)
Tuple([1, 2])
Tuple[1, 2]

Both of the classes have some auxiliary methods:

• length / arity - which returns number of values inside tuple
• first / last / second (only pair) - which returns a corresponding elements
• [] that gives you an access to a particular elements
