yaml VS dyff

For the last six years I've primarily been coding in Golang. Primarily against k8s. It is painful that the defacto YAML library for Go (https://github.com/go-yaml/yaml) is neither a YAML 1.1 nor a YAML 1.2 encoder/decoder.

Technically that qualifies as yaml, so you could maybe use go-yaml/yaml

Is it possible to replicate this (or something on those lines) in GoLang? I've tried go-yaml 3.0.0 but i've got no luck. I've gotten something with go-gypsy 1.0.0 (as seen below) but i was not able to use it...

Unfortunately, all Go YAML parsers that I know of, including the most commonly used go-yaml (originally created by Canonical), will choke when you try to parse such YAML into interface{}, because they try to force it into a Go map, which has many limitations on keys. And you cannot unmarshal it into ny Go map, either, for the same reason.

I see if you go to the project page with no parameters, Github presents you the v2 branch. Be sure to check out the v3 branch, which I've been using. It allows better access to the parse tree during unmarshaling, and I've used it to good effect. For instance, I have a "notification" unmarshaler that allows you to do either:

I personally used dyff https://github.com/homeport/dyff it helped a lot when seeing exactly what was going to change.

had good results using https://github.com/homeport/dyff

I had the same question some years ago. Since I was also interested in the finer details of possible differences, like order changes or type changes, I decided to write a library and CLI myself: github.com/homeport/dyff.

I use dyff (https://github.com/homeport/dyff) as the output is easy to read.
