Output formats

[tonyfosterdev]

It would be cool to enable various format options for output. We could call the current format "human", but json would be cool too.

Kubectl supports this with the -o flag.

The main use case here would be to allow for scripting support in conjunction with tools like jq.

Great idea!

@tonyfosterdev at least for the describe command as a workaround you can use yq to convert to json - as the format you call "human" is actually yaml.

There is one caveat though. The yaml has color codes in some places which yq chokes on. To get past that we need another workaround and use sed to strip that out. The end result:

kcctl describe connector http3 | sed 's/\x1b\[[0-9;]*m//g' | yq eval -o json

Update: https://picocli.info/#_heuristics_for_enabling_ansi (in particular point 7.) looks helpful if we want to get rid of the sed workaround.

That's an interesting observation, @jornh. Note that the YAML output for describe is mostly incidental though, it was not a conscious decision and we may derive from this being YAML in some cases.

I am lacking this issue exactly. I've tried with the workaround using yq but it's not working for me. Thanks anyway for the wonderful tool Gunnar!
