Hello!

I have (again) some ruby code to beautifulize 🙂

I have 2 Range {1…x} and {1…y} and a name  
My goal is to have formatted names like : name + y + x

For example:  
rack11 rack12 rack13  
rack21 rack22 rack23

Can I do nicer than:

{1…y}.each do |y|  
{1…x}.each do |x|  
the\_name = name + y.to\_s + x.to\_s  
end  
end

???

Arnaud.

If you want something one liner,

([‘rake’]_(x_y)).zip((1…x).to\_a_y,(1…y).to\_a_x).each{|z|puts “#{z}”}

Or

((1…x).to\_a_y).zip((1…y).to\_a_x).each{|z|puts “rake#{z}”}

Regards,

Park H.

and another one liner:

puts (0…x\*y).map{|i| “#{name}#{i%x+1}#{i/x+1}”}

cheers

The cartesian\_product method doesn’t exist, you would have to write it.  
It’s trivial

(1…y).cartesian\_product((1…x)).map { |x| name + x.join("") }

Here’s a one-liner for ya:

(1…x).map{|x| (1…y).map{|y| “rack#{x}#{y}”}}.flatten
