   Hi @ieugen, are you suggesting that we change clj-yaml to build on top of SnakeYAML 2.x?

   Are there any user-visible benefits from that upgrade?

   FWIW, in recent projects at CircleCI, I've taken to using SnakeYAML directly, rather than clj-yaml. I don't expect the folks at CircleCI to put in any major investment in this library at present.

   If I may chime in, as an outsider:

   • the latest snakeyaml-engine release was 2.3 (2021-04-19)
     • it's still active (https://bitbucket.org/snakeyaml/snakeyaml-engine/commits/), though
   • the "original" library (https://bitbucket.org/snakeyaml/snakeyaml/commits/) is still in active development as well.
     • latest version of the original library is 1.30 (2021-12-14)

   So I'm not exactly sure which is the "new" library, and what the difference between the APIs is, and what improvements to switching.

   There is a Google Group (https://groups.google.com/g/snakeyaml-core), is someone is interested in venturing deeper.

   Cheers

   As far as I understand, the biggest difference is that snakeyaml supports YAML 1.1, whereas snakeyaml-engine supports YAML 1.2.

   My usecases of YAML all involve very simple YAML files, so I can't bring to mind a clojure use-case where this would matter.

   Thank you, @wongjoel . I agree that this is the biggest difference between snakeyaml and snakeyaml-engine. Looks like YAML 1.2 is designed to move it closer to a superset of JSON (i.e., explicitly support JSON).

   There's also some internal changes to make smaller modules it looks like. Some references:

   • https://en.wikipedia.org/wiki/YAML#Comparison_with_JSON
   • https://groups.google.com/g/snakeyaml-core/c/L0Tf21ONvaI

   Migration to snakeyaml-engine would be a nice addition, but probably a low priority. We can throw the YAML 1.2 files from the spec at the unit tests and see what happens. If I have the time, I'll take a stab at it. ;)

   Doesn't snakeyaml use snakeyaml-engine internally?

   I don't think so.

   • Separate web pages
     • https://bitbucket.org/snakeyaml/snakeyaml/src/master/

   SnakeYAML is a YAML 1.1 processor for the Java Virtual Machine version 7. For YAML 1.2 (which is a superset of JSON) you may have a look at SnakeYAML Engine

   • https://bitbucket.org/asomov/snakeyaml-engine/wiki/Home
   • separate releases in Maven Central

   Trying snakeyaml engine as the "backend" of this lib would likely solve #35
