-- | Extract and apply patches to JSON documents.
--   
--   This is a small library for working with changes to JSON documents. It
--   includes a library and two command-line executables in the style of
--   the diff(1) and patch(1) commands available on many systems.
@package aeson-diff
@version 1.0.0.0


-- | This module implements data types and operations to represent the
--   differences between JSON documents (i.e. a patch), to compare JSON
--   documents and extract such a patch, and to apply such a patch to a
--   JSON document.
module Data.Aeson.Diff

-- | Describes the changes between two JSON documents.
data Patch
Patch :: [Operation] -> Patch
[patchOperations] :: Patch -> [Operation]

-- | Pointer to a location in a JSON document.
--   
--   Defined in RFC 6901 <a>http://tools.ietf.org/html/rfc6901</a>
data Pointer

-- | Traverse a single layer of a JSON document.
data Key

-- | Traverse a <a>Value</a> with an <a>Object</a> constructor.
OKey :: Text -> Key

-- | Traverse a <a>Value</a> with an <a>Array</a> constructor.
AKey :: Int -> Key

-- | An <a>Operation</a> describes an atomic change to a JSON document.
--   
--   See RFC 6902 Section 4
--   <a>http://tools.ietf.org/html/rfc6902#section-4</a>.

[changeValue] :: Operation -> Value

-- | Compare two JSON documents and generate a patch describing the
--   differences.
diff :: Value -> Value -> Patch

-- | Apply a patch to a JSON document.
patch :: Patch -> Value -> Result Value

-- | Apply a patch to a JSON document.
--   
--   If the patch cannot be cleanly applied an <a>error</a> is thrown.
patch' :: Patch -> Value -> Value

-- | Apply an <a>Operation</a> to a <a>Value</a>.
applyOperation :: Operation -> Value -> Result Value

-- | Format a <a>Patch</a> for reading by humans.
--   
--   For storing or exchanging <a>Patch</a>es between systems using the
--   JSON encoding implemented by the <a>FromJSON</a> and <a>ToJSON</a>
