rcl VS pkl-go

Cue and RCL are both json supersets, though in very different ways. Cue is based on graph unification, while RCL is a more traditional functional language. Both are typed, though the type systems are very different. Like RCL, Cue can be used to query json documents, but in RCL this is a first-class feature with similar ergonomics to jq.

Jsonnet is quite similar to RCL: both are json supersets that add variables and functions in similar ways. Jsonnet is dynamically typed, while RCL features an optional gradual type system. Where Jsonnet draws inspiration from Go, RCL draws inspiration from Python and Rust.

Like Nickel, RCL is a gradually typed functional configuration language. Where Nickel has Haskell-like syntax, RCL has C/Rust/Javascript-like syntax with inspiration from Python.

RCL can query json documents on the command line, with a more intuitive language than jq. See https://rcl-lang.org/#intuitive-json-queries and https://docs.ruuda.nl/rcl/rcl_query/.

I'm working on adding floats to the RCL configuration language (https://rcl-lang.org/) to finally deliver on the json superset promise. Blog post coming soon!

If you're looking for a human-friendly json superset (comments, non-quoted keys) that can also abstract away repetitive configuration with variables and list comprehensions, check out https://rcl-lang.org/.

This has been a good driver for me to add features to https://rcl-lang.org/. I just added List.sort for today’s problem.

The RCL configuration language, https://rcl-lang.org / https://github.com/ruuda/rcl. Lately I'm working on support for floats to complete the json superset promise. Also I added a shorthand for "query --format=raw" to make it more useful as a jq replacement.

I don't believe that's true, they have pkl in other languages, too, and I double checked it doesn't require the jre https://news.ycombinator.com/item?id=40146077 (tl;dr = https://github.com/apple/pkl-go/blob/v0.6.0/.circleci/config... which shows both pkl-go as well as how they, themselves, use a single-binary in a circleci setup)

I haven't tried to integrate pkl-go into something like glasskube so I am open to that part being painful because software gonna software, but I believe the general statement of pkl being Java-only is incorrect

https://github.com/apple/pkl-go/blob/v0.6.0/.circleci/config... seems to imply it's "curl && chmod" so maybe you're thinking of developing pkl itself?

I happened to have a container that I am certain contains no Java and it fired right up

  $ docker run -it --rm --entrypoint=/usr/bin/env public.ecr.aws/aws-cli/aws-cli:2.15.38 bash -c 'curl -fsSLO https://github.com/apple/pkl/releases/download/0.25.3/pkl-linux-aarch64; chmod a+x pkl-linux-aarch64; ./pkl-linux-aarch64 --help'

sadly the Go implementation is bloated as hell:

no thank you.
