Readme for aeson-yaml-1.1.0.1

[back to package description]

aeson-yaml

BSD3-licensed, pure Haskell library to encode any Aeson value as YAML.

Usage

import qualified Data.Aeson.Yaml as Aeson.Yaml

Aeson.Yaml.encode :: ToJSON a => a -> LazyByteString

-- To encode multiple values, separated by '---' (YAML documents),
-- use `encodeDocuments`.
Aeson.Yaml.encodeDocuments :: ToJSON a => [a] -> LazyByteString

-- To encode values of different types, use `toJSON` from `Data.Aeson`
-- like so:
encodeDocuments [toJSON x, toJSON y, toJSON z]

See bin/JsonToYaml.hs for a simple command-line application using this library.

Documentation

Hackage

License

BSD3

Motivation

This library does not depend on any external YAML library with C bindings, like yaml, or a restrictive license, like HsYaml (GPLv3). Note, though, that this library can only be used for encoding, not decoding.

This library also works with GHCJS and Eta.
