YAML no reorder data at loading

Ruby
1

Hi,
I want to load the following yaml content:

Yellow: 1
Blue: 2
Red: 3

And build two arrays: one for keys, that must be in this order:

[‘Yellow’, ‘Blue’, ‘Red’] and another for values:

[1, 2, 3]

How can I do that?

Thanks

As far as I can tell, you can’t. This is because the notation

key: value

in YAML represents a hash, which is sorted in an arbitrary order. If you
want
to keep the order, the simplest way is to replace the YAML hash with a
nested
list:

  • [Yellow, 1]
  • [Blue, 2]
  • [Red, 3]

I hope this helps
