With clj-yaml is there anyway to retain comments that exist in the file? I am trying to work with a helm chart values file that has loads of useful comments that I want to retain.

a quick google on snakeyaml + comments leads us here: https://github.com/oyse/yedit/issues/15#issuecomment-224613193 so probably no, in the same manner that an EDN or Clojure s-expression parser does not preserve comments

mmer09:08:50

Thanks. This is where the tension between files being for human and computers is an issue. The comments are really useful to explain to auser what they should be doing.

borkdude09:08:37

Maybe you can just use string fields as comments then

This question seems to point at some option in snakeyaml: https://stackoverflow.com/questions/76781250/how-to-use-snakeyaml-setprocesscomments-on-loaderoptions-and-dumperoptions

mmer10:08:56

Is there any chance of exposing those options?

borkdude10:08:22

you can just use snakeyaml directly, right

mmer10:08:35

In bb?

borkdude10:08:08

I guess we could expose some options here: https://github.com/clj-commons/clj-yaml/blob/ab980163accdaf679090dc5ee93e7858e18768f0/src/clojure/clj_yaml/core.clj#L106 Feel free to file an issue + a PR which includes tests.
