Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Apple releases Pkl – onfiguration as code language
My employer uses a combination of Protocol Buffers (for the config schema definition) and Bazel/Starlark (for concrete instantiations). Configs are validated at build time and runtime using CEL (https://github.com/google/cel-spec).

CEL for admission controller with ValidatingAdmissionPolicy in K8s 1.26
The Common Expression Language (CEL) implements common semantics for expression evaluation, enabling different applications to more easily interoperate. https://github.com/google/cel-spec

Pure Ruby implementation of Google Common Expression Language
Looks like Google invented a specification for a simple "expression language." -> https://github.com/google/cel-spec/blob/master/doc/langdef.md. Writing the expressions feels like writing Java, C++, Go, or TypeScript code. Google then released C++ and Go versions of this langauge as a library.

A library for evaluating expressions like Google Common Expression Language but for Java
https://github.com/google/cel-spec unfortunately, it's in Go or C++. Of course I can write a binding to them. But is there any other similar that you would know of for Java? My other course of action would be to offload computation to another service using this library in Go, or Jsonnet or Open Policy Agent/Rego based evaluation, which I'd prefer not to. Executing JS in Java via Nashorn also an option but it'd be heavy weight.

JsonLogic
Having a standard way to share expressions does seem quite useful, especially when it's multilingual.

Question about setting up multiple applications using nginx.
Especially when dealing with more complex match rules, I personally much prefer Caddy's matchers over building some weird-ass if constructs in Nginx. It also supports CEL for request matching, giving you access to extremely powerful logic, if you need it.

JsonLogic
We built a rust version of this that provides a Python package via CFFI and a node package via WASM, because we found that the different implementations for different languages were pretty buggy and would sometimes resolve expressions differently. Also the original project in JS seems to be largely unmaintained. The rust version goes to great lengths to reimplement weird JS typecasting so as to be fully compatible with the original.
https://github.com/Bestowinc/json-logic-rs
I am currently working on an extension to add functions and more strongly typed operators to avoid the hassle of JS’ type conversion.
What are some alternatives?
When comparing cel-spec and json-logic-rs you can also consider the following projects:
jsonlogic - Go Lang implementation of JsonLogic
json-logic-js - Build complex rules, serialize them as JSON, and execute them in JavaScript
jaspr - Modern web framework for building websites in Dart. Supports SPAs and SSR.
secure-json-logic - Use logic-objects from uncertain sources and run them locally without breaking the own system
sci - Configurable Clojure/Script interpreter suitable for scripting and Clojure DSLs
jsedn - javascript implementation of edn
dhall-lang - Maintainable configuration files
policy_sentry - IAM Least Privilege Policy Generator
