# nu-json [![crate](https://img.shields.io/crates/v/nu-json.svg?style=flat-square)](https://crates.io/crates/nu-json) > a fork of [serde_hjson](https://crates.io/crates/serde-hjson). > The changes made to this crate are kept in [CHANGELOG](/crates/nu-json/CHANGELOG.md). The Rust implementation of Hjson is based on the [Serde JSON Serialization Library](https://github.com/serde-rs/json). This crate is a Rust library for parsing and generating Human JSON [Hjson](https://hjson.github.io). It is built upon [Serde](https://github.com/serde-rs/serde), a high performance generic serialization framework. # Install This crate works with Cargo and can be found on [crates.io](https://crates.io/crates/nu-json) with a `Cargo.toml` like: ```toml [dependencies] serde = "1" nu-json = "0.76" ``` ## From the Commandline Add with: ``` cargo add serde cargo add nu-json ``` # Usage ```rust extern crate serde; extern crate nu_json; use nu_json::{Map,Value}; fn main() { // Now let's look at decoding Hjson data let sample_text=r#" { # specify rate in requests/second rate: 1000 array: [ foo bar ] }"#; // Decode and unwrap. let mut sample: Map = nu_json::from_str(&sample_text).unwrap(); // scope to control lifetime of borrow { // Extract the rate let rate = sample.get("rate").unwrap().as_f64().unwrap(); println!("rate: {}", rate); // Extract the array let array : &mut Vec = sample.get_mut("array").unwrap().as_array_mut().unwrap(); println!("first: {}", array.first().unwrap()); // Add a value array.push(Value::String("baz".to_string())); } // Encode to Hjson let sample2 = nu_json::to_string(&sample).unwrap(); println!("Hjson:\n{}", sample2); } ``` # DOCS At the moment, the documentation on [serde_hjson](https://docs.rs/serde-hjson/0.9.1/serde_hjson/) / [serde_json](https://docs.rs/serde_json/1.0.93/serde_json/) is also relevant for nu-json.
