How to specify ranges in YAML?

I can express

3rd page is the title page

in YAML

title: 3

What about the following?

Pages 10 to 15 contains chapter 1

One way is

chapter 1: [10, 11, 12, 13, 14, 15]

I would prefer a range here. Is there anything like that in YAML?

chapter 1: (10..15)

** Update **

The following would be my alternative if there is no such thing as range in YAML

chapter 1:
   start page: 10
   end page: 15
Solution

  • There is not direct way to specify ranges in YAML, but some YAML can store serialized objects, for example in Ruby:

    ...
normal range: !ruby/range 10..20 
exclusive range: !ruby/range 11...20 
negative range: !ruby/range -1..-5 
...
