Read YAML and output TOML

[Karmaki]

I was wondering if there is a way to take a YAML file as input, and output a TOML file? Since you are handling both formats, I thought it should be possible, but if it is, I do not find how.

Thanks in advance for your answer, and thanks for your nice tool.

Try this:

cat pyproject.toml | tomlq --yaml-output . > pyproject.yaml

cat pyproject.yaml | yq --toml-output . > pyproject.toml

Thank you very much for your answer.

I missed --toml-output option because it is not listed in my yq --help, and indeed, cat pyproject.yaml | yq . is OK, but with --toml-output, I get:

yq: Error running jq: _ConvertError: Invalid type <class 'NoneType'>.

My version is:

$ yq --version
yq 3.2.3

Maybe this is a new option?

The option is undocumented on purpose. It has been there for as long as TOML support has been there.

Can you paste the contents of your pyproject.toml?

[kislyuk]

Ah, I think I know what's happening there. You are trying to convert a YAML file with null values into TOML, which does not support them.

Filed #183

I'm going to close this issue since there is no bug that I can identify aside from that.

Sorry for the delay of my answer. Indeed, this was the problem. Thank you very much for your answer and for the new ticket.
