[ bsd3, json, library, text, web, yaml ] [ Propose Tags ]

This library exposes functions for encoding any Aeson value as YAML. There is also support for encoding multiple values into YAML "documents".

This library is pure Haskell, and does not depend on C FFI with libyaml. It is also licensed under the BSD3 license.

Readme for aeson-yaml-1.0.3.0

[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.

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.
