Question

I would like to combine arrrays @a, @b, and @c into a single array with multiple data elements, for example OpenStruct:

@a = ["my", "foo", "bar"]
@b = ["yan", "can", "cook"]
@c = ["in", "your", "dreams"]

the output would be like:

[
  { :a => "my",  :b => "yan",  :c => "in" },
  { :a => "foo", :b => "can",  :c => "your" },
  { :a => bar,   :b => "cook", :c => "dreams" }
]

What is the fastest way to do this? Should I consider another class?

Answer 1

Here is one solution, I am not quite convinced it is the neatest though:

@a.zip(@b, @c).map {|t| {:a => t[0], :b => t[1], :c => t[2]}}
