Is it possible to add to the name of a hash while running through an
iteration? What I'm trying to achieve:

SomeArray.each do |i, name, content|
info[i+1] = { "name" => name, "content" => content }
end

So that I can call, for example info[1] [name] or info[5][content]...

Make info an Array and just use

info << { :name => name, :content => content }

Kind regards

Is this what you want?

SomeArray.each_with_index do |(name,content),i|
...
end

Each with index worked for me - didn't realize each variable in the
array has an index that can be called. Thanks!

Not exactly. The 'each_with_index' method just yields the array index to
the block being called.

Inside it will be implemented something like this:

module Enumerable
def each_with_index
i = 0
each do |elem|
yield elem, i
i += 1
end
end
end

But you could consider it like this:

class Array
def each_with_index
size.times do |i|
yield self[i], i
end
end
end
