Linter friendly YAML output

[abitrolly]

YAML files produced by dump are not linter friendly.
Example dumped.yaml is attached.

require 'psych'

loaded = Psych.load_file('feature_flags.yaml')
#puts loaded

#puts Psych.methods
File.write 'dumped.yaml', Psych.dump(loaded)

$ yamllint dumped.yaml
feature_flags.yaml
  4:3       error    wrong indentation: expected 4 but found 2  (indentation)
  5:81      error    line too long (82 > 80 characters)  (line-length)
  12:81     error    line too long (82 > 80 characters)  (line-length)
  19:81     error    line too long (82 > 80 characters)  (line-length)
  26:81     error    line too long (82 > 80 characters)  (line-length)
  33:81     error    line too long (82 > 80 characters)  (line-length)
  34:23     error    trailing spaces  (trailing-spaces)
  40:81     error    line too long (82 > 80 characters)  (line-length)
  47:81     error    line too long (82 > 80 characters)  (line-length)
  54:81     error    line too long (87 > 80 characters)  (line-length)
...

So how to produce linter friendly YAML with Psych?

The problems occurs when building GitLab Docs https://gitlab.com/gitlab-org/gitlab-docs/-/merge_requests/3160

I don't have a plan to support the linter tool like yamllint.

If you reconsider to make YAML in Ruby stdlib more flexible, here is link of what is possible https://yamllint.readthedocs.io/en/latest/configuration.html#default-configuration
