## Introduction
|
||
|
|
|
||
|
|
This `dhall-yaml` package provides a Dhall to YAML compiler, `dhall-to-yaml-ng`,
|
||
|
|
and a tool for deriving Dhall from YAML code: `yaml-to-dhall`.
|
||
|
|
|
||
|
|
Tutorials for the analogous JSON tools are available in the `dhall-json` package:
|
||
|
|
|
||
|
|
* [`dhall-to-json`](https://hackage.haskell.org/package/dhall-json/docs/Dhall-JSON.html)
|
||
|
|
|
||
|
|
* [`json-to-dhall`](https://hackage.haskell.org/package/dhall-json/docs/Dhall-JSONToDhall.html)

|
|
## Example
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ dhall-to-yaml-ng <<< "{ foo = [1, 2, 3], bar = { baz = True } }" > example.yaml
|
||
|
|
$ cat example.yaml
|
||
|
|
bar:
|
||
|
|
baz: true
|
||
|
|
foo:
|
||
|
|
- 1
|
||
|
|
- 2
|
||
|
|
- 3
|
||
|
|
$ yaml-to-dhall '{ foo : List Natural, bar : { baz : Bool } }' < example.yaml
|
||
|
|
{ bar = { baz = True }, foo = [ 1, 2, 3 ] }
|
||
|
|
```
