Feature request for the 6 version: add YAML format support

[aborruso]

Hi @johnkerl , YAML is now a very popular file format. Miller already support JSON and I think that in GO there are a lot of YAML libraries.

It would be very convenient to be able to use a yaml file, as today it is already possible with a json file (I mean with the same limitations).

Thank you

[johnkerl]

@aborruso thanks!

Support for a subset of YAML, is doable. Full YAML I don't want to deal with -- including possible cyclic references.

[JensRoland]

I think a subset of YAML is really all that is needed, since complex/ridiculous self-referential YAMLs are likely not tabular in nature anyway, and I suspect almost all Miller users are using it to wrangle tabular-like data.

@aborruso @JensRoland thanks for the bar-lowering reassurances!! ;)

Does either of you have some examples of some YAML data you'd like to be able to process using Miller?
