## Project history and usage

jrsonnet is a Rust implementation of Jsonnet, the data-templating language used to generate JSON and configuration data. It packages both a Jsonnet library and a command-line executable, positioning itself as an alternative to the original C++ implementation and the Go and Scala implementations.

### Project history

The public GitHub repository was created in May 2020 under CertainLach's project namespace and later appeared under the deltarocks organization while retaining redirects from the original URL. The README describes the project as an experiment in implementing Jsonnet in Rust, with additional syntax experiments and bindings beyond the CLI.

### Adoption history

Adoption is niche and mostly package-manager driven: the README documents NixOS packaging, Homebrew packaging on macOS, release binaries for Windows and Linux, crates.io publication, and language bindings including Python and WebAssembly/JSR. Homebrew packages the 0.4.2 release from the GitHub tag archive.

### How it is used

Users reach for jrsonnet when they want a Rust-native Jsonnet evaluator, a drop-in-style libjsonnet shared library, or bindings that expose Jsonnet evaluation inside other Rust, Python, JavaScript, or C/C++ environments.

### Why package nerds care

jrsonnet matters to package-tooling people because Jsonnet is common in infrastructure configuration, and alternative implementations change the performance, embedding, and distribution story. A Rust Jsonnet implementation with crates.io, Nix, Homebrew, Python, and WebAssembly surfaces is exactly the sort of cross-ecosystem packaging knot that nerds notice.

### Timeline

- 2020: Public GitHub repository created for the Rust Jsonnet implementation.
- 2022: Pre-release builds in the v0.5.0 series began appearing on GitHub releases.
- 2026: Homebrew packaged jrsonnet 0.4.2 from the GitHub tag archive.

### Related projects

- Related projects include Google's original Jsonnet implementation, go-jsonnet, sjsonnet, rsjsonnet, and rjsonnet-py, the Python bindings built on jrsonnet.
