YAML hash of array (ruby <-> perl)

Ruby
1

Hi, I am using yaml to pass data between ruby and perl.

Given the data of h={“a”=>[1,2]}, perl’s YAML gives the result of
a:

  • 1
  • 2

while ruby gives the result of, by YAML.dump(h)
a:

  • 1
  • 2

Note there is no space after “a:”, while perl’s have space

Therefore, the data provided by ruby could not be used by perl.
Is this considerd valid YAML?

Thanks!

I get a space after “a:”

irb(main):020:0> YAML.dump(h)
=> “— \na: \n - 1\n - 2”
