  3. kcl

    KCL Programming Language (CNCF Sandbox Project). https://kcl-lang.io

  4. rcl

    A reasonable configuration language

    Project mention: A Common Lisp jq replacement | news.ycombinator.com | 2025-05-02

    If like me you can do basic queries in jq, but as soon as it gets slightly more complex (e.g. filter objects where some nested property that may not exist has a particular value), you wish you could do it with familiar Python/Rust/Javascript-like expressions and map/filter, try https://rcl-lang.org/#intuitive-json-queries.

  5. serde-gura

    Strongly typed Gura library for Rust
