Not to be confused with “pickle”, the Python object serialization format…

JSONSchema covers a lot of various schema needs and YAML is something a lot of developers are comfortable with. I know both of those technologies are not popular here in HN but YAML type-checked and editor-autocomplete-enabled using JSONSchema is a solid choice for configurations in my opinion.

So this is like jsonnet, sdlang and cuelang? What does Pkl do different?

it's very brave to release a new configuration language with no Python support today.

I thought it odd that the language bindings didn't include the most popular langage, Python. In fact, Python seems not to be mentioned at all in the linked page. So I'm wondering, is it 1) Because the developers of Pkl are Python haters 2) Because the developers of Pkl are so overawed by Python that they can't imagine Pkl contributing anything useful to the Python ecosystem In either case, having suffered so much usi…

Is it really that deep?

I'm sorry, can someone explain why one would want to translate from one data description language to another (Pkl -> JSON, or whatever)? Why not just write JSON (or whatever) to begin with?

I like it. I wish Helm used objects instead of string templating. Hopefully it becomes a popular alternative.

In what sense is this programmable?

Can I write a loop in this? If? Elvis operator? A simple map lookup?

So like cue [0] but more primitive, less principled and in java?
