Eg. I wish I could use yq to [...]
have custom indent for list/arrays.

related to #194

Note:

• how to questions should be posted in the discussion board and not raised as an issue.
• V3 will no longer have any enhancements.

Describe the solution you'd like
If we have data1.yml like:
(please keep to around 10 lines )

country: Australia
  province: space
citizen:
  - 1
  - 2

And we run a command:

yq --no-list-indent '.' data1.yml

it could output

country: Australia
  province: space
citizen:
- 1
- 2

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

yq --list-indent 0 '.' data1.yml

Additional context

Unfortunately this parameter is not exposed by the underlying yaml parser (go-yaml) - until it is not much can be done.

As a workaround for this issue I pipe the yaml through a yamlfmt command like yamlfmt -in -formatter indentless_arrays=true.

that is a cool tip. Thanks!

The kubernetes team have this problem too. They have forked go-yaml and applied a fix: https://github.com/kubernetes-sigs/yaml/blob/master/goyaml.v3/patch.go
