[help-needed]: Is there a way to parse and dump a yaml file and preserving the format of array/sequence?

See original GitHub issue

I would like to know if it’s possible to pass options to the parser and/or the dump methods to preserve the format of the arrays and sequence as it is originally in the file. Right now , when running the dump, I get the following transformation:

node_version: ["12", "14"]

node_version:
          - "12"
          - "14"

@oscard0m , yes and no.

node_version: ["12", "14"] is parsed into JS object { node_version: [ 12, 14 ] }, which does not have the information about formatting, as you can see yourself.

However, you can override yaml types to make node_version: ["12", "14"] to parse to whatever you like, and store format information somewhere there.

Look at custom types, might find a few ideas here: https://github.com/nodeca/js-yaml/issues/613#issuecomment-814319894
