Pkl was one of the best internal tools at Apple, and it’s so good to see it finally getting open sourced.

My team migrated several kloc k8s configuration to pkl with great success. Internally we used to write alert definitions in pkl and it would generate configuration for 2 different monitoring tools, a pretty static documentation site and link it all together nicely.

Would gladly recommend this to anyone and I’m excited to be able to use this again.

Was about to ask if you had k8s api models available internally, and that someone should create some tool to generate that from the spec. But turns out it already exists in the open!

Why yes, I would like to see more of those in my k8s, so glad we finally have the technology

Coming from yaml+kustomize, all those curly braces are a tough sell. It looks like they roughly double the number of lines in the file.

While I learned to accept YAML it messes up editor usage.

It is so sensitive that basic text editing like copy and paste, tab, in/decreasing indent never quite do what I expect in IntelliJ.

I paste parts of yaml into another yaml and it ends up somewhere unpredictable.

Curly braces are great at ensuring correctness though, as goto fail; has shown.
