YAML: Why --- changes to ...

[maximbaz]

I'm not sure if this is a bug or intended behavior. I noticed that --- changes to ..., and for example kubectl (kubernetes tool) cannot parse my yaml files because of this.

I tried to find what is the difference, found this page, but after reading the description I still have no clue why ... in the example below is better than ---.

Honestly, I have never seen ... being used in YAML files until today. I can easily imagine that it's a problem in kubectl, that it should support ..., but if there is no difference, can we make prettier prefer --- over ...?

--parser yaml

Input:

one:
  key: 1
---
two:
  key: 2

Output:

one:
  key: 1
...
two:
  key: 2

Expected behavior:

one:
  key: 1
---
two:
  key: 2
