Introduction

This dhall-json package provides a Dhall to JSON compiler, and a Dhall to YAML compiler based on that. The dhall-to-yaml executable is a "basic" version of the dhall-to-yaml-ng executable in the dhall-yaml package.

Example

$ dhall-to-json <<< "{ foo = 1, bar = True }"
{"foo":1,"bar":true}
$ dhall-to-json <<< "List/head Natural ([] : List Natural)"
null
$ dhall-to-yaml <<< "{ foo = [1, 2, 3], bar = { baz = True } }"
foo:
- 1
- 2
- 3
bar:
  baz: true

Development

This package's dhall-to-yaml and dhall-yaml's dhall-to-yaml-ng should be kept as closely in sync as possible. Common code for these executables lives in this package, tests live in dhall-yaml.
