A Rust implementation of the Jsonnet language. Currently, it targets Jsonnet version 0.20.
This project provides three crates:
- rsjsonnet: a command line program with an interface similar to the official implementation.
- rsjsonnet-lang: a library that provides parsing and evaluation of Jsonnet programs.
- rsjsonnet-front: a library built on top of rsjsonnet-lang and provides easy source loading and error printing.
You can download binaries of the command line for Linux and Windows from the GitHub releases page.
If you have a Rust toolchain installed on your system, you can build the latest version with:
cargo install --locked rsjsonnetrsjsonnet provides a command line interface similar to the one of the official implementation.
Usage: rsjsonnet [OPTIONS] <filename>

-S, --string Expect a string, manifest as plain text
-s, --max-stack <n> Number of allowed stack frames
-t, --max-trace <n> Max length of stack trace before cropping
-V, --ext-str <var[=val]> Provide an external variable as a string
