YAML Spec Versioning

[Blacksmoke16]

Discussion

The YAML is currently all based on YAML 1.1 spec, which debuted in 2005. However, it seems as of 2009, the YAML 1.2 spec was finalized, and most recently in 2021, https://yaml.org/spec/1.2.2/ is now the latest version.

I'd like to start a discussion on what should be done about this. I.e. should we update to support 1.2? Should we also support 1.1 still? Should we do what Go did and do something in-between?

It seems that YAML 1.2 has some of its own problems: https://ruudvanasseldonk.com/2023/01/11/the-yaml-document-from-hell. But 1.1 also has its own as well: Blacksmoke16/oq#129 and #13821.

Out of all of this, adding support for https://yaml.org/spec/1.2.2/#102-json-schema could be quite handy as well, esp for oq.

IIRC LibYAML only supports 1.1, for 1.2 you need something like https://github.com/pantoniou/libfyaml

Found https://github.com/yaml/libyaml/wiki/YAML-1.2, seems like there is some support but not 100%. Was suggested to use that lib if 100% 1.2 support is needed.
