# Description
playing with the NUON format in Rust code in some plugins, we agreed
with the team it was a great time to create a standalone NUON format to
allow Rust devs to use this Nushell file format.
> **Note**
> this PR almost copy-pastes the code from
`nu_commands/src/formats/from/nuon.rs` and
`nu_commands/src/formats/to/nuon.rs` to `nuon/src/from.rs` and
`nuon/src/to.rs`, with minor tweaks to make then standalone functions,
e.g. remove the rest of the command implementations
### TODO
- [x] add tests
- [x] add documentation
# User-Facing Changes
devs will have access to a new crate, `nuon`, and two functions,
`from_nuon` and `to_nuon`
```rust
from_nuon(
input: &str,
span: Option<Span>,
) -> Result<Value, ShellError>
```
```rust
to_nuon(
input: &Value,
raw: bool,
tabs: Option<usize>,
indent: Option<usize>,
span: Option<Span>,
) -> Result<String, ShellError>
```
# Tests + Formatting
i've basically taken all the tests from
`crates/nu-command/tests/format_conversions/nuon.rs` and converted them
to use `from_nuon` and `to_nuon` instead of Nushell commands
- i've created a `nuon_end_to_end` to run both conversions with an
optional middle value to check that all is fine
> **Note**
> the `nuon::tests::read_code_should_fail_rather_than_panic` test does
give different results locally and in the CI...
> i've left it ignored with comments to help future us :)
# After Submitting
mention that in the release notes for sure!!
