# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.

nu-json

crate

a fork of serde_hjson.

The changes made to this crate are kept in CHANGELOG.

The Rust implementation of Hjson is based on the Serde JSON Serialization Library.

This crate is a Rust library for parsing and generating Human JSON Hjson. It is built upon Serde, a high performance generic serialization framework.

Install

This crate works with Cargo and can be found on crates.io with a Cargo.toml like:

[dependencies]
serde = "1"
nu-json = "0.76"

From the Commandline

Add with:

 cargo add serde
 cargo add nu-json

Usage

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<String, Value> = 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<Value> = sample.get_mut("array").unwrap().as_array_mut().unwrap();
        println!("first: {}", array.get(0).unwrap());

        // Add a value
        array.push(Value::String("tak".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 / serde_json is also relevant for nu-json.
